How to prevent fogging of glass doors(supermarket display fridges)?

For supermarkets and convenience stores, the fog on the glass of supermarket display fridges can prevent customers from viewing their products and may reduce impulsive purchases.

Why does the glass door condense fog?
Compared with cold air, hotter air can hold more moisture. "Dew point" is the temperature at which the air cools to saturation when the water vapor content in the air is constant and the air pressure is kept constant. A glass of ice water will begin to sweat in a warm room because the air in contact with the glass is cooled to the dew point. The same thing happens when the colder surface of the glass door comes into contact with the hotter air in the building.

How to solve this problem?
Replace damaged components
A damaged door gasket may allow humid air to enter the walk-in room. This air will cool to the dew point and lose excess moisture, which will produce mist. If you have a heated door, the foggy door may indicate that you need to replace the heater wire. Some heated glass doors have anti-sweat controls and may not work properly.

Adjust thermostat
Try to raise the temperature in the walk-in cooler slightly, or raise the surface temperature of the door to a temperature that does not cause water to condense on the door. It can also be cooled by setting an air conditioner, which helps absorb more moisture from the air near the walk-in radiator. You can try using a dehumidifier to help remove excess moisture from the air.

Buy new glass door
If you are in the new glass door market, please consider buying models with heated glass or anti-fog coating. Under high humidity conditions, these coatings cause condensation to form a transparent layer instead of forming misty droplets. APEX provides a glass door model that does not sweat. Newer doors usually have better thermal insulation, which will result in a lower surface temperature and less condensate.

Selection of liquid packaging machine

Whether you are building a new plant or automating an existing plant, considering a separate machine or investing in a complete production line, buying modern equipment is a difficult task. In addition to improving operational efficiency, it should also not affect product quality and hygiene.

There are many aspects and standards to consider when choosing the best liquid packaging machine for your business.
Product details
Define your product viscosity. Is it fluid or watery or semi-viscous? Still sticky? This will help you determine the type of packing that is right for you. The piston filling machine works well for thick and viscous products, while the gravity filling machine works better for thinner fluid products.

Biotechnology or medical products require aseptic filling in a sterile environment; chemical products require fire and explosion-proof systems. Before deciding to use a liquid packaging machine, such details must be listed.

Container
When considering using a liquid packaging machine, be sure to specify the type of container to be filled. Do you want to fill soft bags, four packs or bottles? If it is a bottle, what is the size, shape and material? Glass or plastic? What type of cover do I need? Crimp cap, fill cap, gland cap, tighten, spray – there may be countless options.

Level of automation
Even if it is the first attempt to perform automatic liquid filling, the daily or annual output should be determined. Defining production levels makes it easier to calculate the speed or capacity of the machine to be considered per minute / hour. The selected machine should have the ability to grow as the operation grows.

The number of bottles per minute required to meet production needs will help you determine a manual, semi-automatic or fully automatic packaging system. For small batch production, semi-automatic or even manual liquid packaging machines are meaningful. When the production volume increases or new products are introduced, you can upgrade to a fully automatic product, which can greatly increase the filling speed.

Integration
Whether the new liquid packaging machine you intend to purchase can be integrated with existing equipment, or even with equipment purchased in the future. This is critical to the overall efficiency of the packaging production line and to avoid future jamming by outdated machinery.

Accuracy
Filling accuracy is the main advantage of automatic packaging systems. Insufficient filling of the container will cause customer complaints, while overfilling is a waste that you cannot afford.
Automation can ensure accurate filling. The automatic filling machine is equipped with PLC, which can control the filling parameters to ensure consistent and accurate filling of product flow. Eliminate product overflow, which not only saves money by saving products, but also reduces the time and expense spent cleaning the machine and surrounding area.

HOSNG provides food packaging system, medicine packaging system and customized packaging system. Through the integration of packaging system, they can be smoothly integrated into your operation.

What is the cause of the collision of the CNC lathe machine?

In the field of machine tool processing, the problem of knife collision is a major headache. It may seem trivial to hit the device with a knife, but it is very harmful. As a high-speed and high-precision automatic precision equipment, the machining center will affect the machining efficiency once the collision of the knife is light, and the precision will be reduced due to the heavy impact. Therefore, we must pay attention to the problem of knife collision in our daily processing.

Operator error
According to the statistics of the production line, most of the causes of tool collisions in machining centers are caused by operator errors. For example, during the tool setting process, the speed of the machine tool's drive shaft was too fast, which caused tool collisions. The other is that the coordinate values ​​of the machine tool axes are entered incorrectly, which leads to tool collision during spindle machining. This is the reason for the largest number of tool collisions in the machining center. Therefore, improving the professionalism and responsibility of the machining center operator is the best way to prevent the machining center from hitting the knife, especially the responsibility of the machining center operator.

In fact, the damage to the machine tool caused by the collision of the machining center is very serious, especially the damage to the machining accuracy of the machine tool is irreversible. Especially for high-precision machine tools, it is easy to lose accuracy after a few hits, and the surface does not seem to change much. In fact, the accuracy of the machine tool is no longer.

Workpiece clamping failure
The reason for the second machine tool collision is the failure of the clamping of the machining workpiece. The machining workpiece is loose during the machining process, and the parts will be moved by the cutting force of the tool. At this time, it is easy to cause the collision of the cutter, and it is also easy to cause the workpiece to throw out the fixture, and even break the door and window glass of the machine. accident.

For many automatic processing production lines, there may be clamping errors caused by inaccurate positioning of parts. For example, when a robot places a part on a jig, the placement position is deviated, which causes the part to be clamped in place. If there is no corresponding workpiece in-position detection switch, the tool may collide with the tool during the feeding process. And because the automatic production line is a fully automated process, during the process, the operator does not intervene in the machining of the machine tool, it is difficult to artificially find the problems caused by the clamping, which further increases the probability of knife collision.

Machine tool motion failure
The so-called machine tool failure means that the operating system of the machine tool is out of control. For example, when the machine tool executes a machining program, its machining trajectory does not follow the trajectory of the machining program, but a large deviation occurs. At this time, the machine tool will collide with the tool.

Therefore, the orderly, timely, and professional operation and maintenance of processing CNC lathe machine is very important. Do not use processing CNC lathe machine overload, otherwise it will be worth the money.

The difference between Digital night vision goggles and infrared thermal imager camera

working principle

1. Working principle of infrared night vision

The principle of infrared night vision is generally to collect and enhance the existing light through the eyepiece to focus the light on the image intensifier, and then inside the intensifier, a photocathode will be activated by light, so that the photon energy can be converted These electrons are accelerated through an electrostatic area located inside the booster, and then hit the phosphor surface screen, and then form an image visible to the human eye. To put it simply, the principle of night vision is actually to convert the signal from the target invisible light, low light or infrared light into an electrical signal, and then amplify the electrical signal to convert it into an optical signal visible to the human eye. .

2. Working principle of Digital Night Vision

Digital Night Vision generally processes and converts this low-illumination light into a digital electrical signal through a high-sensitivity image sensor, and then transmits it to a miniature liquid crystal display inside the night vision device.

So from the description of the working principle above, it can be seen that the core components of infrared night vision and digital night vision are different. The former generally uses an image intensifier, while the latter uses an image sensor, which is the main difference between the two. .

The application environment of the two is different

Infrared night vision can only be used in low light or full black conditions. In the presence of strong light and during the day, it will be limited by the imaging principle, so it cannot be used normally. If it is activated, it needs to be covered with the objective lens cover from the light inlet Viewing in the middle, but even the use of infrared night vision during the day is still not significant, which is not as clear as the naked eye.

Digital night vision goggles is completely independent of the ambient light. The use mode can be adjusted to day or night mode. It is a day and night all-weather photoelectric instrument. It is color imaging during the day, black and white or green imaging at night.

Will the thickness of aluminum alloy doors and windows affect performance?

Since the development of the construction industry, as people's needs have changed, many aspects of their concepts have changed. For example, the doors and windows have now been changed to aluminum alloy doors and windows made of aluminum alloy. Now consumers' requirements for doors and windows are not only beautiful, but also important. Regarding safety, it is widely believed that the thicker the doors and windows, the better, so is the thicker the better? Let's analyze it for everyone

Is the thicker the better?

First of all, the thickness of aluminum alloy doors and windows is not as thick as possible. The choice of thickness is based on the use of the environment and other factors according to the principle of mechanics. If the material used is small, there will be hidden dangers. If it is used too much, it will cause unnecessary waste and the cost of consumers will also To improve, in general, the thickness of doors and windows can be divided into 1.4, 1.6, 1.8, and more than 2.0, not the thicker the material, the better, but to choose the appropriate.

Generally speaking, the force thickness of the window should not be 1.4 mm, the main force part of the door should not be less than 2 mm, the thickness of the force part of the window should not be less than 1.4 mm, and the main force part of the door should not be less than 2 mm.
