What aspects of rapid cnc prototyping need attention?

In the rapid cnc prototyping process of injection molded parts, the injection molding machine works fast under high pressure, high speed and high temperature. The injection mechanism is a high pressure, high speed and local high temperature machine. , I need to remind colleagues to pay attention to the following dangerous areas:

In the feeding area, the high temperature screw is rotating, so do not put iron rods or other foreign objects in it. Material tube area, this area is the raw material heating area, high temperature is easy to burn. In the nozzle area, where the rubber is sprayed under high pressure, there is a danger of splashing or scalding.
The mold area, which is a high-speed and high-voltage switch action area, is quite dangerous. Raw materials may also be sprayed from the mold clamping surface, so special care must be taken. The mold support area has strong mechanical movements and requires special care. The clamping mechanism ---- with high-speed and strong mechanical movements, is a precaution for the rapid molding of injection molded parts.

Common types of uhf rfid readers

uhf rfid readers wireless radio frequency identification, through the radio frequency identification signal to automatically identify the target object and obtain related data, without human intervention, can identify high-speed moving objects and can simultaneously identify multiple RFID tags, the operation is fast and convenient.

The more common ones in the market are: desktop card issuers, split fixed readers, integrated fixed readers, mobile handhelds, portable readers, and industrial embedded readers.

Desktop card issuer. This type of reader is generally used to initialize the RFID tag data of the card issuer. It can read, write, authorize, format and other operations on the tag. Use. Its characteristics: small size, low cost, short reading distance.

     Split-type fixed reader, RFID read-write module and read-write antenna are separated. Different reader modules and antennas can be configured according to different application scenarios. Common antennas are 6DB, 8DB, 12DB, etc., near-field antennas and Far-field antennas are available. In addition, the reader also has single-channel, dual-channel, four-channel and eight-channel, and a maximum of 32-channel antenna interfaces. It can be widely used in intelligent manufacturing and supply chain, digital warehouse management, commercial retail, assets. Management and other fields.

Integrated fixed reader. The biggest feature of this type of reader is that the uhf rfid readers module and antenna are assembled into an integrated machine. It has strong anti-interference ability, excellent protection performance, convenient installation and use, and high cost performance. It is mainly used for license plate anti-counterfeit identification management. , Intelligent parking lot management, warehouse material access control and identification management, airport luggage and parcel identification management, intelligent manufacturing and other fields.

      Mobile handheld, handheld reader's biggest feature is mobility and portability. The operating system mainly has two operating systems: Android and win CE. The interface design is friendly. The RFID reading distance is from 0-8 meters. The quality is directly related to the RFID read-write chip module and the built-in antenna.

Purchase and correct maintenance of solid wood tv cabinet furniture

The tv cabinet furniture can not only place the TV, but also a decorative cabinet. A beautiful TV cabinet can effectively improve the overall visual effect of the living room space. The solid wood TV cabinet is made of wood, which has more perfect plasticity and health and environmental protection. The solid wood TV cabinet is divided into ordinary TV cabinet and combined TV cabinet. Let's take a look at the purchase and correct maintenance of solid wood TV cabinets together.

Because there are too many electrical appliances in the TV cabinet, you must fully consider the heat dissipation performance of the TV cabinet when purchasing to ensure the normal use of various electrical appliances. In order to place new appliances in the future, it is better to reserve some space. Whether the wiring of the TV cabinet is convenient and feasible, and whether it can give full play to the functions of electrical appliances.

According to the family's usual habit of watching TV, pay attention to the height of the TV cabinet when choosing 30-40 cm is more reasonable when buying, but also fully consider its bearing capacity. The style, color, and material of the TV cabinet must be coordinated with the decoration style of the living room, so that it can better create some highlights visually.

In daily life, always use a clean soft cloth to wipe the dust on the surface of the TV cabinet. Try to avoid the gravity switch of the TV cabinet door and push-pull drawers, especially for TV cabinets with glass inlaid on the door panel.

Many TV cabinets are connected by hardware. After a long time of use, there will be some noises and unsmooth push-pull. Pay attention to clean up the dust and debris, and add some lubricants regularly. The TV cabinet has dirt. You can choose to dilute the olive oil with water and wipe it with a soft cloth to ensure that the wooden door cabinet is more bright and bright.

Adjustment method of vibratory polishing machine

Vibratory polishing machine workpiece processing, the first is to put the workpiece into the container barrel, the container is vibrated up and down and left and right through special devices, so that the parts and the grinding medium friction with each other. The quality of the finishing process often depends on the vibration frequency and amplitude. The processing can be adjusted by the following methods:

The vibration source is generated by a vibration motor. Two ends of the vibration motor main shaft are equipped with two eccentric blocks. By adjusting the relative position and weight of the eccentric block, the turning speed and vibration force can be adjusted. If the turning speed of the vibrator is slow, you can adjust the upper eccentric block to the 12 o'clock position of the clock and attach an iron plate to the upper eccentric block to increase the weight of the upper eccentric block; if the vibration force is weak, you can set the upper eccentric block Adjust the eccentric block to the 12 o'clock position and the lower eccentric block to the 7-9 o'clock position. It should be noted that if it is necessary to frequently adjust the turning speed of the vibration grinder, it is more convenient and accurate to connect an external frequency converter. After the adjustment is completed, the machine gate must be closed in time to avoid danger.

 

What is the size of the Self Service Food Ordering System?

See the difference between the width of the Self Service Food Ordering System equipment. Rotary hot pot equipment and rotary sushi equipment are very simple. The width of the rotary hot pot equipment is 55cm, and the equipment for rotary sushi is 45cm. Just take a ruler to measure the width, or you can look at the crescent sheet. The rotating leaves of the hot pot equipment are 18-20, which is very easy to identify.

After checking the motor, it is clear whether the merchant wants to sell you a rotary hot pot device or a rotary sushi device. Then you can look at the core part of the rotary hot pot device-the motor. Because regular business of rotary hot pot equipment will be maintained for life, they will choose purely imported motors. Check the nameplate of the motor to know whether it is domestic or imported. Be sure to identify the pure imported brand, otherwise the operation may be unstable in the later stage.
