[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-2 The present invention provides the following embodiments:
[0021] An antistatic PET protective film cutting fixture includes a bracket assembly 110 and a guide assembly. The bracket assembly 110 is used to hold the antistatic PET protective film roll 220. The bracket assembly 110 is provided with a mounting slot 111. The two ends of the insertion shaft 210 that passes through the antistatic PET protective film roll 220 are located in the mounting slot 111. The insertion shaft 210 is adapted to the slot in the middle of the antistatic PET protective film roll 220. The height of the insertion shaft 210 is greater than the height of the antistatic PET protective film roll 220. The two ends of the insertion shaft 210 are round and can be directly placed in the mounting slot 111.
[0022] A guide assembly is located in the bracket assembly 110. The guide assembly is used to separate the antistatic PET protective film roll 220. After separation and guidance by the guide assembly, the antistatic PET protective film roll 220 is peeled off and pulled out along the bottom of the bracket assembly 110, facilitating subsequent cutting operations. This allows the rolled antistatic PET protective film roll 220 to be disassembled into strips or blocks of film products. The overall structure of this utility model is simple, making the installation of the antistatic PET protective film roll 220 more convenient; its modular design also facilitates later inspection and maintenance.
[0023] As a preferred embodiment of this utility model, the bracket assembly 110 includes a base plate and two vertical upright plates, with an antistatic PET protective film roll 220 located between the two upright plates. Specifically, referring to the accompanying drawings, the upright plates are located at the rear end of the base plate and are vertically designed. An installation structure can be provided on the base plate to connect the fixture to the cutting device.
[0024] As a preferred embodiment of this utility model, the mounting slot 111 is located at the upper corner of the upright plate, and the mounting slot 111 is designed at an angle. The bottom of the mounting slot 111 is semi-circular, and the outer wall of the insert shaft 210 fits against the bottom of the mounting slot 111, thus combining... Figure 1 Specifically, the angled design allows for loading and unloading from above the fixture. The weight of the antistatic PET protective film roll 220 ensures that it is in the correct position. The angled design also provides space for maneuvering when installing or removing the antistatic PET protective film roll 220.
[0025] In another preferred embodiment of this utility model, the guiding assembly includes a first guide roller 310, a second guide roller 320, and a third guide roller 330. The first guide roller 310 is used to peel off the antistatic PET protective film roll 220. The second guide roller 320 is located above and between the first guide roller 310 and the third guide roller 330, and the third guide roller 330 allows the peeled antistatic PET protective film roll 220 to pass between it and the base plate. The first guide roller 310 mainly serves a separating function, the second guide roller 320 is used for guiding and reversing, and the third guide roller 330 is used for limiting movement. This design is reasonable, and after cutting, the separated end of the antistatic PET protective film roll 220 is not easily retracted. The ends of the first guide roller 310, the second guide roller 320, and the third guide roller 330 rotate between themselves and the upright plate.
[0026] As another preferred embodiment of this utility model, a cutting groove is provided on the bottom plate in front of the No. 3 guide roller 330. According to the attached figure, there is a distance between the cutting groove and the No. 3 guide roller 330. After the cutting is completed, the remaining end extending from the bottom of the No. 3 guide roller 330 can be clamped or adsorbed to achieve continuous automated cutting.
[0027] Insert the insert shaft 210 into the antistatic PET protective film roll 220, keeping the exposed portions of the insert shaft 210 roughly the same. Then, place the antistatic PET protective film roll 220 with the insert shaft 210 between the upright plates at the rear end of the bracket assembly 110, with both ends of the insert shaft 210 located in the mounting slot 111. Manually peel off the front part of the antistatic PET protective film roll 220, pass it around the bottom of the first guide roller 310, then around the top of the second guide roller 320, and finally through the bottom of the third guide roller 330. The operation is simple and convenient.
[0028] The antistatic PET protective film cutting device includes the aforementioned cutting fixture, as well as an automatic cutting mechanism and a pulling mechanism. The automatic cutting mechanism is a cutting blade that can automatically rise and fall. After the cutting blade descends, it falls into the cutting groove to achieve cutting. The pulling mechanism is used to pull the antistatic PET protective film roll 220 that passes through the bottom of the third guide roller 330. The pulling mechanism can be length-set to ensure accurate cutting length.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
