[0022] Embodiment 1:

[0023] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a reflective film cutting device, including a workbench 1, a feeding roller 4 is arranged on the top of the workbench 1, a rotating roller 5 is arranged on the top of the workbench 1, a cutting box body 6 is fixedly installed on the top of the workbench 1, a cylinder 7 is fixedly installed inside the cutting box body 6, a cutting knife body 8 is arranged at the output end of the cylinder 7, a positioning mechanism 2 is arranged on the top of the workbench 1, and a cleaning mechanism 3 is arranged inside the cutting box body 6.

[0024] Furthermore, the positioning mechanism 2 includes a motor 21 fixedly installed on the front surface of the workbench 1. A bidirectional threaded rod 22 is fixedly installed at the output end of the motor 21. A limit block 23 is threadedly installed on the outer side of the bidirectional threaded rod 22. A fixed box 24 is fixedly installed on the top of the workbench 1. A first spring 25 is fixedly installed inside the fixed box 24. One end of the first spring 25 away from the fixed box 24 is fixedly installed with a lifting block 26. A top roller 27 is rotatably installed on the top of the lifting block 26, so that the limit block 23 is always on the side of the reflective film roll to limit it, effectively avoiding the phenomenon of deviation when it is conveyed to the bottom of the cutting box body 6, thereby improving the cutting effect of the reflective film.

[0025] Furthermore, the limit block 23 is slidably installed on the outer sides of the feeding roller 4 and the rotating roller 5. There are two groups of limit blocks 23, which are symmetrically distributed with respect to the center line on the left side of the workbench 1, and are respectively threadedly installed on the outer parts of the two ends with opposite thread directions of the bidirectional threaded rod 22, so that the limit block 23 is always on the side of the reflective film roll to limit it.

[0026] Furthermore, the lifting block 26 is slidably installed inside the fixed box 24. The top roller 27 is in contact with the bottom of the rotating roller 5 under the action of the first spring 25, so that the reflective film is continuously in contact with the rotating roller 5 during the conveying process, effectively avoiding it being more smooth during the conveying process.

[0027] Embodiment 2:

[0028] Please refer to Figure 4 , and in combination with Embodiment 1, it is further obtained that the cleaning mechanism 3 includes a mounting frame 31. The mounting frame 31 is arranged at the bottom of the cutting box body 6. A second spring 32 is fixedly installed inside the mounting frame 31. One end of the second spring 32 away from the mounting frame 31 is fixedly installed with a sliding frame 33. A cleaning brush 34 is rotatably installed inside the sliding frame 33. A third spring 35 is fixedly installed inside the cutting box body 6. One end of the third spring 35 away from the cutting box body 6 is fixedly installed with a plug 36. A pull rod 37 is fixedly installed at the end of the plug 36 close to the third spring 35, cleaning the debris adhered to the surface of the cutting knife body 8 due to cutting, and preventing the debris from affecting subsequent cutting operations.

[0029] Furthermore, there are two groups of cleaning mechanisms 3, which are symmetrically distributed with respect to the center line on the front surface of the cutting box body 6. The sliding frame 33 is slidably installed inside the mounting frame 31. Slots are opened at the corresponding positions of the mounting frame 31 and the plug 36, and the plug 36 is inserted into the slots to clean the cutting debris on the surface of the cleaning brush 34 and ensure the subsequent cleaning effect.

[0030] During the actual operation process, when this device is in use, the reflective film to be cut is passed through between the feeding rollers 4, and then through between the rotating roller 5 and the top roller 27. The motor 21 is started, and the output end of the motor 21 drives the bidirectional threaded rod 22 to rotate. The rotation of the bidirectional threaded rod 22 causes the two limit blocks 23 to move towards each other, thereby performing a limiting and positioning operation on the reflective film. Moreover, the top roller 27 is always in contact with the reflective film under the action of the first spring 25, so that the limit blocks 23 are always on the side of the reflective film roll to limit it, effectively avoiding the phenomenon of deviation when it is conveyed to the bottom of the cutting box body 6, thereby improving the cutting effect of the reflective film and being beneficial to the improvement of the product qualification rate. The top roller 27 is elastically held against the bottom of the reflective film roll through the first spring 25, so that the reflective film continuously contacts the rotating roller 5 during the conveying process, effectively avoiding it being more smooth during the conveying process. The cylinder 7 is started, and the output end of the cylinder 7 pushes the cutting knife body 8 to cut the reflective film. After the cutting knife body 8 moves upward, the cleaning brush 34 continuously contacts the cutting knife body 8 under the action of the second spring 32, thereby cleaning the debris adhered to the surface of the cutting knife body 8 due to cutting, preventing the debris from affecting the subsequent cutting operation. When the cutting operation is completed, the pull rod 37 is pulled outward. After the insertion block 36 is pulled out by the pull rod 37 and disengaged from the limit of the mounting frame 31, the mounting frame 31 is removed, and the cutting debris on the surface of the cleaning brush 34 is cleaned to ensure the subsequent cleaning effect.

[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
