[0002] Plastic films are made of polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS) and other resins, and are widely used in packaging and lamination layers. In the process of cotton bailing, the use of high-performance plastic films is crucial. Such films usually need to have excellent strength, tear resistance and moisture-proof performance to ensure the safety and quality of cotton during transportation and storage. In order to produce high-performance plastic films, a composite film blowing machine is an essential device. This device can compound different types of resins through multi-layer co-extrusion technology to form films with multiple functions, meeting the increasing performance requirements of the market for packaging materials.

[0003] In the prior art, most film blowing machines usually adopt the method of production while collecting, but many devices lack effective tension control in the collection stage, which may cause wrinkles or slack on the film surface, affecting product quality, and may further cause the film to tear or damage during the cotton bailing process, thus affecting the overall product quality and subsequent use.

[0004] Therefore, those skilled in the art provide a composite film blowing machine to solve the problems raised in the above background art. Content of the Utility Model

[0037] When the blowing machine is in use, the first servo motor 202 drives the threaded rod 203 to rotate, so that the push rod 205 can drive the frame 206 and the driven roller 207 inside to move, thereby adjusting the gap between the driving roller 208 and the driven roller 207, and providing a certain tension to the plastic film during the conveying process, effectively preventing problems such as film wrinkles, slack or stretching caused by uneven tension, significantly improving the product quality, and effectively ensuring the reliability and durability in subsequent use.

[0038] Referring to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6, the dust removal structure 3 includes a second support 301.

After more dust is adsorbed by the electrostatic dust removal plate 308 on one side, the second servo motor 302 provided can drive the rotating roller 306 to rotate, so that the electrostatic dust removal plate 308 on the other side can quickly move to the dust-adsorbing place for dust suction. At the same time, the electrostatic dust removal plate 308 that adsorbs dust can rotate to the other side for convenient disassembly and replacement, ensuring that the blown film machine can complete dust removal and replacement without stopping during the production process, significantly improving the production efficiency;

[0040] The collection structure 4 includes a third support 401. On one side of the third support 401, a third servo motor 402 is provided.

On one end face of each of the multiple springs 309, a clamping block 310 is fixedly connected. The outside of each of the multiple clamping blocks 310 is snap-fitted with an electrostatic dust removal plate 308.

The first support 201, the second support 301, and the third support 401 are all fixedly connected to the base 1. The design of the fixed connection increases the structural stability and overall durability of the device, ensuring the reliability of the device during operation.

[0043] Working principle: When using this film blowing machine, the plastic film is first produced by the machine body 6 and conveyed to the upper end of the collecting roller 406 for collection. During the collection process, the first servo motor 202 drives the threaded rod 203 to rotate, thereby driving the push rod 205, the frame 206, and the driven roller 207 inside to move, adjusting the gap between the driving roller 208 and the driven roller 207. This adjustment can provide an appropriate tension force during the conveyance of the plastic film, preventing problems such as film wrinkles, slackness, or stretching caused by uneven tension force, thus significantly improving the product quality. At the same time, the electrostatic dust removal plate 308 is used to adsorb dust after the plastic film is produced. When one side of the electrostatic dust removal plate 308 adsorbs more dust, the second servo motor 302 drives the rotating roller 306 to quickly move the electrostatic dust removal plate 308 on the other side to the dust adsorption position for dust removal. In addition, the electrostatic dust removal plate 308 that has adsorbed dust can be rotated to the other side for convenient disassembly and replacement, so that dust removal and replacement can be completed without stopping the machine during the production process, improving the production efficiency.

[0044] Finally, it should be noted that the above are only the preferred specific embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing specific embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
