Description

Technical Field

[0001] The utility model relates to the field of packaging devices, in particular to a negative pressure lifting conveyor belt device for producing PVA films for electronic products. Background Art

[0002] In the process of electronic product packaging, food film bags are needed. Film bags are small bulk packaging containers with good moisture-proof performance, beautiful and generous. They are one of the more popular packaging materials in China. Film bags are based on paper-plastic composite bags or kraft paper bags. The specifications and sizes are based on customer requirements. After curling and laminating processes, a layer of waterproof glossy film is applied on the surface of the bag, and then it is heat-sealed through sewing processes;

[0003] A Chinese patent discloses an easily adjustable transmission device for electronic production (authorization announcement number CN 108529134A). The patented technology can better adjust the conveying angle of the device, improving the adjustability and stability of the device. However, in the existing electronic product packaging process, the lifting mode of the electronic product film bag is relatively old, and the effect of coordination with the transmission during processing is poor. Manual bag separation is required, and there is no effective negative pressure lifting effect, which leads to an increase in work intensity in the early stage of filling the food film bag.

[0004] Therefore, those skilled in the art provide a negative pressure lifting conveyor belt device for producing PVA films for electronic products to solve the problems raised in the above background technology. Utility Model Content

Through the four triangular tables at the bottom of the workbench, the user can support the entire device to improve the convenience of use. The user can control the start and stop and forward and reverse rotation of the motor through the controller. The above is an existing known technology and will not be described in detail. A movable plate is fixed at the upper end of the spring, and a storage slot is opened inside the movable plate. The storage slot is used to place the film. Several conveying rollers are arranged on the upper part of the workbench.

[0008] A fixing frame is arranged on the air pipe, and the other end of the fixing frame is arranged on the plate body for fixed connection.

[0009] Technical effects and advantages of the utility model:

[0010] The utility model arranges an air pump, an air pipe and a suction cup. When the air pump is turned off, the suction cup loses its adsorption force, and the film bag previously adsorbed by the suction cup will fall onto the conveying roller, thereby completing the purpose of negative pressure lifting. Finally, as the food film bag in the movable plate is gradually lifted by the negative pressure, the load-bearing capacity of the movable plate is reduced, and the spring will carry the movable plate to gradually move upward, thereby improving the fit.
