Description

Technical Field

[0001] The utility model relates to the field of TPU processing equipment, in particular to a processing device which is convenient for cutting a protective film TPU. Background Art

[0002] The new reinforced plastic elastomer (TPU) protective film, a new environmentally friendly material, is safe, non-toxic, harmless, and recyclable, with a wide range of applications. Its performance features high tension, high pulling force, and high load-bearing capacity. Its tensile strength is rated at no less than 550 kg / cm² in both the longitudinal and transverse directions. The TPU film is cut and laminated to the inside of a cardboard box. When in use, electronic products are placed between the protective film and the box, and the box is folded into a square box for effective protection.

[0003] This protective film is generally sliced ​​in the form of a roll film and cut into appropriate lengths to fit on the paper box. Due to the high elasticity of the protective film itself, during the cutting process, the film is easily stretched, resulting in the length of the sheet being lower than the set standard. On the other hand, the film's strong and tough characteristics make it difficult to cut the film, and the cutter surface will produce jagged edges.

[0004] To solve this problem, the protective film production equipment was modified to add a set of unwinding and laminating equipment during the production of protective film. After the protective film is extruded and cooled, the unwinding equipment draws out a PET release film with a thickness of no less than 0.05mm. The laminating equipment then smoothly bonds the protective film and PET film. The film is then reeled and slit to form a protective film roll with a PET liner. This effectively solves the problems of scale mismatch and jagged edges that occur when cutting the film roll into slices. Therefore, based on the above description, this application proposes a processing device that facilitates the cutting of TPU protective films. Utility Model Content

Multiple winding rollers 8 can simultaneously wind up multiple film bodies 1, and the conveying roller 3 is used to convey the film body 1. The driving roller 15 and the conveying roller 3 cooperate to achieve mutual adhesion between the PET release film and the film body 1, thereby enhancing the performance of the TPU film body 1. In this way, through the combination of the driving roller 15, the feeding roller 6, the first motor 5, the first pulley 13, the second pulley 14 and the belt 7, when the TPU film body 1 is wound, it is protected by the PET release film, and the force is evenly distributed during the subsequent winding to prevent it from stretching. At the same time, when it is subsequently attached to the surface of the packaging material and cut, it avoids burrs due to cutting or deformation caused by stretching during application, thereby ensuring that the TPU film body 1 has good packaging material performance.

[0029] The winding roller 8 is provided with retaining rings 9 on both sides of the middle part, which are used to keep the winding roller 8 from tilting when winding. One end of the winding roller 8 passes through the winding frame 2, and one end of the winding roller 8 that passes through the winding frame 2 is engaged with a second motor 17 through a clamping groove 16. The second motor 17 is the driving source of the winding roller 8. The clamping groove 16 is provided on the driving end of the winding roller 8 and the second motor 17, so that the driving ends of the winding roller 8 and the second motor 17 can be directly engaged or directly removed. The second motor 17 is fixed inside the winding frame 2, and a fixing block 10 is hinged on the winding frame 2 at both ends of each winding roller 8.

The second pulley 14 and the first pulley 13 are connected by a belt 7. The first motor 5 is used to provide drive to the feed roller 6 and the driving roller 15 so that they can rotate at the same linear speed.

[0030] Working principle: When in use, the TPU film 1 passes through the conveyor roller 3 in turn and reaches between the conveyor roller 3 and the driving roller 15, and then is wound on the winding roller 8. When passing through the driving roller 15, the film 1 on the feed roller 6 will adhere to the PET release film. In this way, the TPU film 1 will have a layer of protective film. When it is unfolded and attached to the surface of the carton or packaging material in the next step, it will not be deformed due to the tension on the surface, nor will it cause burrs due to cutting, thereby improving the performance and effect of TPU use.
