[0002] Polyester release film, as a high-performance functional film material, is widely used in electronic component bonding, optical film lamination, food packaging, and industrial tapes due to its excellent heat resistance, chemical stability, and release properties. Different application scenarios have specific requirements for the length, width, and other dimensional parameters of polyester release film. For example, in the precision assembly process of electronic products, polyester release film of specific lengths and widths may be needed to accurately bond electronic components; in the packaging industry, release films of various sizes are also needed as label backings to accommodate packaging boxes of different shapes and sizes. Therefore, efficiently and accurately cutting long rolls of polyester release film into segments of the required size has become a key step in the production and use of polyester release film. Although current cutting equipment for polyester release film preparation has improved cutting efficiency to some extent, it still has some problems. On the one hand, the cutting size of mechanical cutting equipment is relatively fixed, and its adjustment of cutting size is not flexible enough; on the other hand, the function of this type of equipment is relatively simple, and it can only perform simple straight-line cutting.

[0016] 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.

[0017] This specific embodiment is a cutting device for preparing polyester release film, and its structural schematic diagram is shown below. Figure 1 As shown, the device includes a cutting table 1, a cutting mechanism 5, and a mounting column 6. The mounting column 6 is horizontally mounted on the upper surface of the cutting table 1. One end of the mounting column 6 is rotatably connected to the side wall of the cutting table 1. A drive motor 8 connected to the mounting column 6 is provided on the outer wall of the cutting table 1. The end of the mounting column 6 away from the drive motor 8 is provided with the cutting mechanism 5 on the cutting table 1. A receiving box 2 is provided below the cutting mechanism 5 on the front end face of the cutting table 1.

[0018] Reference Figure 2 The mounting column 6 has a horizontally formed inner groove 9 inside, and an inner screw rod 10 is embedded in the inner groove 9.

[0019] A push ring 12 is slidably sleeved on the outside of the mounting post 6. A connecting rod 11 is fixed to the inner side of the push ring 12, passing through an inner groove 9. A threaded hole is formed on the connecting rod 11, through which an inner screw 10 is threaded. An adjusting head 7 is rotatably inserted into the outer wall of the mounting post 6. The adjusting head 7 is perpendicular to the inner screw 10, and a first bevel tooth and a second bevel tooth, respectively, are installed on the adjusting head 7 and the inner screw 10, which mesh with each other.

[0020] Reference Figure 3The cutting mechanism 5 includes a fixed frame 13, a cutting blade 17, and a lifting plate 15. The fixed frame 13 is vertically fixedly installed on the upper surface of the cutting table 1. A lifting groove 16 is vertically formed on the inner side of the fixed frame 13, and the lifting plate 15 slides along the lifting groove 16. A lifting cylinder 14 is vertically installed on the upper surface of the fixed frame 13, and the telescopic end of the lifting cylinder 14 is fixedly connected to the upper surface of the lifting plate 15. A rotary motor 18 is rotatably installed at the end of the lifting plate 15 away from the fixed frame 13, and the rotary motor 18 drives the cutting blade 17 to rotate.

[0021] Reference Figure 4 The mounting column 6 is symmetrically provided with clamping rods 3 on both sides. The two ends of the clamping rods 3 are respectively connected to mounting brackets 19. The mounting brackets 19 have a U-shaped structure and are slidably embedded in the cutting table 1. The cutting table 1 is equipped with a telescopic cylinder 4 connected to the mounting brackets 19.

[0022] Working principle: Fixing the polyester release film: The polyester release film roll to be cut is placed on the mounting column 6. The telescopic cylinder 4 is started, pushing the mounting frame 19 to slide inside the cutting table 1. Since the two ends of the clamping rod 3 are respectively connected to the mounting frame 19, the clamping rod 3 is moved. The clamping rods 3 on both sides move closer to each other, clamping and fixing the polyester release film.

[0023] When the cutting size needs to be adjusted, the adjusting head 7 is rotated. The first bevel tooth on the adjusting head 7 drives the second bevel tooth on the inner screw 10, which meshes with it, to rotate, thereby causing the inner screw 10 to rotate in the inner groove 9. Because the connecting rod 11 inside the push ring 12 passes through the inner groove 9 and the thread of the inner screw 10 passes through the threaded hole on the connecting rod 11, the rotation of the inner screw 10 will drive the connecting rod 11 and the push ring 12 to move horizontally along the mounting post 6, thereby adjusting the horizontal cutting position of the cutting mechanism 5 relative to the polyester release film. The moving distance of the push ring 12 is the cutting size of the polyester release film roll. After clamping and fixing, the drive motor 8 drives the mounting post 6 to rotate, and then the lifting cylinder 14 is activated. Its telescopic end pushes the lifting plate 15 to slide downward along the lifting groove 16 inside the fixing frame 13, driving the rotary motor 18 and the cutting blade 17 to descend. The rotary motor 18 is activated, driving the cutting blade 17 to rotate at high speed. When the cutting blade 17 descends to contact the polyester release film, it can be cut. The cut polyester release film strips are placed into the receiving box 2 below the cutting mechanism 5 at the front end of the cutting table 1, and then the position is adjusted according to the cutting size requirements of the polyester release film roll.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
