Technical Field

[0001] This utility model relates to the field of thin film processing technology, and in particular to a thin film waste edge removal device. Background Technology

[0002] In the film production process, it is often necessary to trim the edges of the film to ensure its quality and appearance. Traditional methods of trimming film waste edges are often manual, which is not only inefficient but also poses safety hazards. In recent years, although some automated trimming devices have emerged, these devices tend to generate fumes during the cutting process, affecting the operator's vision and also being detrimental to the environment. Therefore, it is necessary to design a device that can efficiently, safely, and environmentally friendly trim film waste edges. Utility Model Content

[0003] The purpose of this invention is to provide a film waste edge removal device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a film waste edge trimming device, comprising a base, a lower blade holder, and an upper blade holder. The lower blade holder is disposed on the top of the base, and a lower cutting blade is disposed on the top of the lower blade holder. A bracket is disposed on one side of the top of the base, and a negative pressure fan is disposed on one side of the bracket. A hydraulic lifting device is installed on the top of the bracket, and an upper blade holder is installed at the output end of the hydraulic lifting device. An upper cutting blade is installed at the bottom of the upper blade holder. The upper and lower cutting blades are heated by electric heating technology.

[0005] Furthermore, one end of the upper and lower tool holders is provided with a cable, and the cable is connected to an external power source to provide power support for the device.

[0006] Furthermore, a tooling frame is provided on the top of the base for fixing the film, which facilitates the cutting operation.

[0007] Furthermore, the negative pressure fan is connected to an external power source, and a protective net is installed on the front of the negative pressure fan to prevent foreign objects from entering the fan while ensuring the normal operation of the fan.

[0008] In summary, this application includes the following beneficial technical effects:

[0009] This utility model's film waste edge trimming device has a high degree of automation, which can greatly improve trimming efficiency and reduce labor costs. In particular, the device has a reasonable structural design, which can heat the upper and lower cutting blades during the cutting process, thereby improving efficiency and ensuring cutting quality. Through the design of negative pressure fans and external pipelines, the problem of smoke and dust is effectively solved, ensuring a clean operating environment and the health of operators.

[0014] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0015] A film waste edge removal device, wherein a base 1 serves as the support structure for the entire device, and a lower blade holder 2 is provided on its top.

[0016] The lower cutter 201 is mounted on the top of the lower cutter holder 2, which is used to cooperate with the upper cutter 401 to complete the cutting operation.

[0017] A bracket 3 is provided on one side of the top of the base 1 to support the negative pressure fan 301 and the hydraulic lifting device 302.

[0018] A negative pressure fan 301 is installed on one side of the bracket 3, and a protective net is provided on the front of the negative pressure fan 301.

[0019] A hydraulic lifting device 302 is installed on the top of the bracket 3, and an upper tool holder 4 is installed at the output end of the hydraulic lifting device 302.

[0020] The upper cutter 401 is installed at the bottom of the upper cutter holder 4, which is used to cooperate with the lower cutter 201 to complete the cutting operation.

[0021] Cables 5 are provided at one end of the upper cutter holder 4 and the lower cutter holder 2. The cables 5 are connected to an external power source to provide power support for the device and to heat the lower cutter 201 and the upper cutter 401.

[0022] The top of the base 1 is equipped with a tooling frame for fixing the film, which facilitates the cutting operation.

[0023] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0024] The implementation principle of the film waste edge trimming device in this application embodiment is as follows: During the cutting process, the hydraulic lifting device 302 drives the upper blade holder 4 and the lower blade holder 2 to cooperate in completing the cutting operation. Simultaneously, the blade is heated during cutting, and the generated fumes can be sucked out by the negative pressure fan 301 to avoid obstructing the view. In actual operation, an external pipe (not shown in the figure) can be connected to the negative pressure fan 301 to discharge fumes outside the device, ensuring a clean operating environment and protecting the health of the operators.

[0025] The foregoing description of an exemplary embodiment of a film waste edge removal device provided by this disclosure refers to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
