[0020] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Refer to the instruction manual Figures 1 to 5 A cutting device for the production of privacy film includes a cutting table 1, a mounting frame 2 is provided on the surface of the cutting table 1, a hydraulic cylinder 3 is installed on the mounting frame 2, the output end of the hydraulic cylinder 3 is connected to a tool holder 31, a cutter is installed at the bottom of the tool holder 31, and a positioning cylinder 32 is provided on the outer sliding sleeve of the tool holder 31. The cutter is located in the inner cavity of the positioning cylinder 32, and an opening is provided at the bottom of the positioning cylinder 32. Scrapers 9 are symmetrically provided between the openings, and a slot 10 is provided on the surface of the opening relative to the scraper 9. One end of the scraper 9 is slidably inserted into the inner cavity of the slot 10. When the cutter moves up and down, the scraper 9 contacts the side of the cutter.

[0022] It should be noted that when cutting the privacy film, the privacy film is located at the bottom of the positioning cylinder 32, the tool holder 31 is used to install the cutter, and the hydraulic cylinder 3 is used to drive the cutter to move continuously downward. The cutter passes through the opening to cut the privacy film, so that after the cutting is completed, the cutter first retracts into the inner cavity of the positioning cylinder 32, and the scraper 9 automatically scrapes and cleans the debris on the surface of the cutter, and then the bottom of the positioning cylinder 32 is separated from the privacy film.

[0023] Furthermore, a second spring 11 is connected to the side of the scraper 9 facing away from the cutter, and the outer end of the second spring 11 is connected to the inner wall of the slot 10 .

[0024] In the above embodiment, when the cutter is inserted into the middle of the scraper 9 by the second spring 11, the scraper 9 can automatically reset and fit the cutter, so that the surface of the cutter always remains clean when cutting the privacy film.

[0025] Furthermore, first transverse plates 6 are symmetrically installed on both sides of the tool holder 31 , the bottom of each first transverse plate 6 is connected to a first spring 8 , the bottom end of the first spring 8 is connected to a second transverse plate 7 , and both ends of the second transverse plate 7 are connected to the positioning cylinder 32 .

[0026] In the above embodiment, the first spring 8 is supported between the first cross plate 6 and the second cross plate 7, so that the cutter is in the inner cavity of the positioning cylinder 32 in a natural state, and in the process of cutting the privacy film, the positioning cylinder 32 can first contact the privacy film and preliminarily position the privacy film. After the cutting is completed, the elasticity of the first spring 8 itself will automatically reset the positioning cylinder 32, so that when the cutter moves upward, the cutter first retracts to the inner cavity of the positioning cylinder 32, so that the scraper 9 can clean the cutter surface in time.

[0027] Furthermore, positioning components are provided at both ends of the second cross plate 7, and the positioning components include slide grooves 33, which are symmetrically opened at both ends of the positioning cylinder 32, and a positioning block 35 is slidably provided in the inner cavity of the slide groove 33, and a through groove is opened in the inner cavity of the positioning block 35, and a baffle 36 is fixedly installed in the middle of the through groove, and coil springs are connected on both sides of the baffle 36, and a shift block 37 is connected to the outer end of the coil spring, and the shift block 37 is slidably inserted into the positioning block 35, and a latch 38 is connected to one side of the shift block 37, and one end of the latch 38 is slidably inserted into the inside of the through groove, and multiple fixed plates 34 are evenly installed on both sides of the slide groove 33, and the other end of the latch 38 is located in the middle of two of the fixed plates 34, and the positioning block 35 is fixedly connected to the second cross plate 7.

[0028] In the above embodiment, by pressing the shift blocks 37 together so that the latch 38 is located between the two fixed plates 34 at an appropriate height and then releasing the shift blocks 37, the distance between the second horizontal plate 7 and the first horizontal plate 6 can be adjusted, thereby adjusting the telescopic distance of the first spring 8 itself, thereby adjusting the pressure of the positioning cylinder 32 when initially positioning the anti-peep film, thereby reducing product damage caused by pressing.

[0029] Furthermore, guide rods 4 are installed on both sides of the inner cavity of the cutting table 1, one of the guide rods 4 is provided with a thread on its surface, and a handle is installed on the guide rod 4 passing through the cutting table 1. Slide rails 5 are symmetrically installed on the cutting table 1, and the slide rails 5 are located on the top of the guide rods 4. The bottom end of the mounting frame 2 is sleeved on the guide rods 4 and the slide rails 5. When the handle is rotated, the mounting frame 2 slides on the surface of the cutting table 1.

[0030] In the above embodiment, the guide rod 4 with threads on its surface can be rotated by rotating the handle, thereby achieving the effect of adjusting the movement of the mounting frame 2 to facilitate adjustment of the cutting position.

[0031] Furthermore, rubber pads 39 are symmetrically installed on the bottom of the positioning cylinder 32 , and the rubber pads 39 are fixedly connected to the positioning cylinder 32 .

[0032] In the above embodiment, the rubber pad 39 contacts the privacy film to provide additional protection for the bottom of the positioning tube 32 , effectively preventing the positioning tube 32 from scratching the surface of the privacy film when positioning the privacy film.

[0033] Working principle: When the device is in use, the cutter is first installed at the bottom of the tool holder 31, and the privacy film is placed at the bottom of the positioning cylinder 32. Then, the cutter is driven downward by the hydraulic cylinder 3. When the rubber pad 39 contacts the privacy film, the bottom of the positioning cylinder 32 initially positions the privacy film through the rubber pad 39. At the same time, the cutter continues to move downward. After contacting the privacy film, the hydraulic cylinder 3 pushes and applies pressure to cut it; after cutting is completed, the cutter is driven upward by the hydraulic cylinder 3. Since the first spring 8 is supported between the first cross plate 6 and the second cross plate 7, the cutter will first move upward after separating from the privacy film and retract into the inner cavity of the positioning cylinder 32. In the process of the cutter passing through the opening, the second spring 11 enables the scraper 9 to always fit the cutter surface, so that the cutter surface is scraped by the scraper 9 during the upward movement of the cutter, so that it is always kept clean and the cutter surface can be cleaned in time.

[0034] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
