DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 6 , a PET protective film processing equipment, including a workbench 1, a plurality of supporting legs 2 are fixedly connected to the lower end of the workbench 1, a collecting hole 3 is opened at the upper end of the workbench 1, and the plurality of supporting legs 2 are fixedly connected by connecting rods, and a collecting box 4 is placed on the plurality of connecting rods. After the punching is completed, the waste on the workbench 1 can be dropped into the collecting box 4 through the collecting hole 3, so as to facilitate the collection of the waste for processing. A U-shaped plate 5 is fixedly connected to the upper end of the workbench 1, an electric push rod 6 is installed at the lower end of the U-shaped plate 5, and a lifting plate 7 is fixedly connected to the telescopic end of the electric push rod 6. A rectangular groove 8 is opened at the lower end of the lifting plate 7, and a tool 9 is arranged below the rectangular groove 8. A mounting block 10 is fixedly connected to the upper end of the tool 9. By inserting the mounting block 10 into the rectangular groove 8, the initial fixation of the tool 9 is realized. The mounting block 10 is opened with a mounting groove 11, and a limiting mechanism for limiting the tool 9 is arranged in the mounting groove 11;

[0024] The limiting mechanism includes two strip plates 12 slidably connected to the inside of the mounting groove 11, the opposite sides of the two strip plates 12 are elastically connected by a first spring 13, the opposite sides of the two strip plates 12 are fixedly connected to the limiting blocks 14, the opposite ends of the two limiting blocks 14 pass through the mounting block 10, and the inner walls on both sides of the rectangular groove 8 are provided with limiting grooves 15 that cooperate with the corresponding limiting blocks 14. By inserting the limiting blocks 14 into the limiting grooves 15, the final limiting fixation of the tool 9 is achieved, and the opposite sides of the two strip plates 12 are fixedly connected with rectangular blocks 16, and the opposite ends of the two rectangular blocks 16 The back ends all penetrate the mounting block 10 and extend to the outside. Through the cooperation of the strip plate 12, the first spring 13 and the limit block 14 and other structures, the removal and installation of the tool 9 are convenient and simple, so that the appropriate tool 9 can be quickly replaced according to the size of the opening. A slide groove 17 is provided in the lifting plate 7. The slide groove 17 is a U-shaped groove. A two-way threaded rod 18 is rotatably connected between the inner walls on both sides of the slide groove 17. A motor 19 is installed on the outer wall of the lifting plate 7. The motor 19 is a servo motor. The end of the output shaft of the motor 19 extends to the inside of the slide groove 17 and is fixedly connected to one end of the two-way threaded rod 18.

[0025] Among them, the two threaded ends of the bidirectional threaded rod 18 are threadedly connected with a movable plate 20, and the two movable plates 20 are slidably connected to the inner wall of the slide groove 17. The lower ends of the two movable plates 20 extend to the outside and are fixedly connected to a connecting plate 21. The lower ends of the two movable plates 20 are fixedly connected to the connecting plate 21. A pressing plate 22 is arranged below the two movable plates 20, and a rubber layer is arranged at the lower ends of the two pressing plates 22. The PET protective film is fixed by the two pressing plates 22 to avoid the displacement of the PET protective film during punching and causing the failure of hole opening. The upper ends of the two pressing plates 22 are provided with a movable groove 23, and the inner bottoms of the two movable grooves 23 are fixedly connected with a second spring 24. The other ends of the two second springs 24 are fixedly connected to the corresponding connecting plate 21. When the tool 9 continues to move downward to open a hole, the elastic action of multiple second springs 24 reduces the pressure of the two pressing plates 22 on the PET protective film to avoid damaging the PET protective film.

[0026] In the utility model, when in use, the motor 19 is first started to rotate the bidirectional threaded rod 18, thereby causing the two moving plates 20 to move with the two pressing plates 22. The spacing between the two moving plates 20 is adjusted to adjust the spacing between the two pressing plates 22, thereby being able to fix PET protective films of different specifications. After the spacing between the two pressing plates 22 is adjusted, the electric push rod 6 is started to move the lifting plate 7 downward until the lower ends of the two pressing plates 22 are in contact with the upper end surface of the PET protective film to fix the PET protective film, thereby avoiding the displacement of the PET protective film during hole opening, resulting in hole opening failure.

[0027] Then, the electric push rod 6 can be started to make the lifting plate 7 continue to move downward, and then the tool 9 moves downward to make a hole in the PET protective film. In this process, the two moving plates 20 move downward with the corresponding connecting plates 21, and the elastic action of the multiple second springs 24 reduces the pressure of the two pressing plates 22 on the PET protective film to avoid damaging the PET protective film. After the hole is made, the waste above the workbench 1 can be dropped into the collection box 4 below through the collection hole 3 for collection and processing;

[0028] When it is necessary to adjust the aperture of the PET protective film, press the two rectangular blocks 16 to make the two rectangular blocks 16 move relative to each other, and move the two strip plates 12 relative to each other, so that the two limit blocks 14 leave the corresponding limit grooves 15. At this time, the tool 9 can be taken out, and then a new tool 9 can be installed. Similarly, press the two rectangular blocks 16 to make them move relative to each other, so that the two rectangular blocks 16 move relative to each other with the corresponding strip plates 12, and then insert the mounting block 10 into the corresponding rectangular groove 8 to achieve the preliminary installation of the new tool 9. Then the two rectangular blocks 16 can be loosened. Under the elastic action of the first spring 13, the two strip plates 12 move back to back, so that the two limit blocks 14 are stuck in the corresponding limit grooves 15, thus completing the installation of the new tool 9. In this way, the removal and installation of the tool 9 are convenient and simple, and it is convenient to quickly replace the appropriate tool according to the size of the opening.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
