[0002] PP packaging film (Packaging Film) mainly refers to the film used for packaging articles, usually including polyethylene film, biaxially oriented polyester (BOPET), BOPP film and CPP film, etc. It is used for wrapping packaging to make the packaging more stable and neat. It is used in foreign trade export, papermaking, hardware, plastic chemicals, building materials, food and medicine industries. The advantage of packaging film is that it is mainly made of a mixture of several different brands of polyethylene resins and has puncture resistance, super strength and high performance. It can wrap the goods stacked on the pallet to make the packaging more stable. It can fit closely to the goods and is suitable for packaging goods of various shapes, making the packaging appearance beautiful. Moreover, it guarantees the hygiene and safety of the goods, with transparency, sealing, fixity (small parts will not fall over during transportation), dust and moisture resistance and other functions. It also has good shock and impact resistance, as well as good protective performance.

[0022] The following are combined to limit the scope of this application: The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in routine experiments.

[0023] Example: A shearing device for packaging film, such as Figures 1-6As shown, it includes a working frame 1, a placement seat 2, a fixed frame 4, a roller 5, a gear 6, a servo motor 7, a limit plate 8, a protective block 9, a first cylinder 10, a cutting block 11, an electric slide 12, a grab frame 13, a second cylinder 14, a clamping block 15 and a support column 20. A placement seat 2 is welded on the inner left side of the working frame 1. A length scale is marked on the right side of the working frame 1. The packaging film size can be cut with reference to the length table. A fixed frame 4 is welded in the middle of the working frame 1. The fixed frame 4 is located on the right side of the placement seat 2. Two rollers 5 are rotatably connected to the fixed frame 4. The front sides of the two rollers 5 are fixedly connected to gears 6. The two gears 6 are meshed with each other. The front side of the fixed frame 4 is fixedly connected to a servo motor 7. The output shaft of the servo motor 7 is fixedly connected to the upper roller 5. The servo motor 7 can drive the upper gear 6 to rotate counterclockwise, so that the upper roller 5 rotates counterclockwise and the lower roller 5 rotates clockwise. The right side of the fixed frame 4 is fixedly connected to a limit plate 8. The limit plate 8 is located on the right side between the two rollers 5, and a protective block 9 is fixedly connected to the top of the working frame 1. Two first cylinders 10 are fixedly connected to the inside of the protective block 9. A cutting block 11 is fixedly connected between the bottoms of the piston rods of the two first cylinders 10. Electric slide rails 12 are fixedly connected to the front and rear sides of the right side of the working frame 1. Grabs 13 are slidably connected to the two electric slide rails 12. Two second cylinders 14 are fixedly connected in the middle of the two grabbers 13. A clamping block 15 is fixedly connected to the piston rod of each second cylinder 14. The clamping block 15 is installed in a shape of left low and right high, which can make the packaging film slide more naturally and prevent wrinkles from occurring. A certain gap is left between the two clamping blocks 15 in front and behind. A groove is provided on the limit plate 8, and the groove is located directly below the cutting block 11, which can better cut the packaging film. Two notches are opened on the right side of the limit plate 8, and the notches correspond to the size of the clamping block 15 on the right side. Support columns 20 are welded around the bottom of the working frame 1.

[0024] like Figure 1 and Figure 2 As shown, it also includes a first transparent cover 3 and a second transparent cover 16. The first transparent cover 3 is rotatably connected to the left side of the upper part of the working frame 1, and the second transparent cover 16 is rotatably connected to the right side of the upper part of the working frame 1. Because the first transparent cover 3 and the second transparent cover 16 are made of transparent materials, the internal situation can be checked, and the first transparent cover 3 and the second transparent cover 16 are both provided with handles 19.

[0025] like Figure 1 、 Figure 2 and Figure 6 As shown, it also includes a placement frame 17, a blocking cover 18 and a handle 19. The placement frame 17 is fixedly connected to the bottom right side of the working frame 1, and the blocking cover 18 is rotatably connected to the front side of the placement frame 17. The handle 19 is fixedly connected to the blocking cover 18.

[0026] When people need to cut the packaging film, they first open the first transparent cover 3, insert the packaging film roll from the rear of the placement seat 2, and then close the first transparent cover 3, and then start the servo motor 7. The servo motor 7 drives the gear 6 to rotate. Through the cooperation of the two gears 6, the roller 5 rotates, the upper roller 5 rotates counterclockwise, and the lower roller 5 rotates clockwise. Then, the packaging film is pulled out from the packaging film roll to between the two rollers 5. The two rollers 5 drive the packaging film to the right, and then start the second cylinder 14. The two second cylinders 14 on the front and rear sides respectively drive the two clamping blocks 15 on the front and rear sides to clamp the packaging film, and then start the electric slide 12 Drive the grab frame 13 to slide to the right, and at the same time pull the packaging film to a certain position, start the first cylinder 10, and the two first cylinders 10 drive the cutter 11 to move downward to cut the packaging film. Then the cylinder is reset, and the cutter 11 is reset at the same time, and the electric slide rail 12 is reset. The groove on the limit plate 8 makes it difficult for the limit plate 8 to rub against the cutter 11, and makes cutting more natural. There is a length table on the right edge of the working frame 1, and the packaging film size can be cut according to the length table. Then the roller 5 continues to drive the packaging film to the right. Because the clamping block 15 is designed to be low on the left and high on the right, the packaging film slides naturally and enters the placement frame 17, making it difficult for the packaging film to wrinkle.

[0027] If you need to continue cutting, operate the first cylinder 10 and the second cylinder 14 again. After cutting the desired amount, turn off the servo motor 7, then open the cover 18 to the right through the handle 19, then take out the cut packaging film, and then close the first transparent cover 3 and the cover 18.

Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
