Description

A production apparatus for a paper bag moisture-proof film made entirely of plant-based composition Technical Field

[0001] This utility model relates to the field of moisture barrier film production technology, and in particular to a production apparatus for a paper bag moisture barrier film made of all-plant composition. Background Technology

[0002] Paper bags typically have a moisture-proof film inside to improve their durability. In current technology, the production of this moisture-proof film requires winding equipment. This type of winding equipment generally uses a motor-driven air shaft to wind the moisture-proof film, while pressure rollers apply pressure to ensure the wound film does not loosen. However, existing winding equipment has the following drawbacks in actual use: 1. The air shaft relies on air bladders to push the expansion blocks to work, which requires a stable air source for power. Once the air source experiences air pressure fluctuations or interruptions, the air shaft cannot operate normally, which will seriously affect the production progress. Moreover, the existing air shaft has a complex structure and high manufacturing cost. Furthermore, the rubber parts such as the air bladders used are prone to aging, resulting in a short service life. Also, because they are not easy to disassemble and assemble, maintenance is difficult. 2. Existing pressure rollers, such as the wrapping machine for film winding proposed in Chinese utility model patent CN221821458U, adopt a fixed design. The film is pressed by the elastic force provided by the spring. As the amount of film wound increases, the pressure of the pressure roller on the film also increases continuously, which makes the subsequent unloading operation extremely inconvenient.

[0019] Working principle: When using this utility model, the take-up drum is placed on the housing 23. The first electric telescopic rod 211 is activated.

The second telescopic rod 32 drives the moving frame 33 to reset, and then the first electric telescopic rod 211 retracts, driving the push block 213 to reset. Under the action of the first spring 210, the expansion block 27 resets, causing the winding drum to lose its lock, at which point unloading can be performed. The first screw 25 is used to fix the second fixed seat 26 to the housing 23. The second fixed seat 26 is used to install the second screw 29. The fixing block 31 is used to install the second telescopic rod 32. The slide 36 is used to install the pressure roller 37. The guide rod 38 is used to guide the slide 36.
