A cutting device for plastic packaging bag production is a device used to cut the plastic film for plastic packaging bag production to specified dimensions.
[0003] Most existing processing and cutting devices transport plastic films via conveyor rollers. However, after prolonged friction between the conveyor rollers and the plastic film, static electricity can easily be generated, causing the film to adhere and affecting the transport. In addition, the film is not pressed and limited during cutting, which can easily lead to film displacement and affect the quality of the final product. In order to address this technical problem, this application proposes a cutting device for processing plastic packaging bags. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cutting device for processing plastic packaging bags. During the conveying process, since both the conveying roller and the card holder are made of metal, when the conveying roller rotates in the card holder inside the protective shell, the wire at the bottom of the card holder can conduct the static electricity generated by long-term friction on the outer wall of the conveying roller to the ground, thus preventing the static electricity from adsorbing the plastic film and affecting the conveying.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A cutting device for processing plastic packaging bags includes an operating table. Multiple fixing blocks are fixedly connected to the top left side of the operating table.

A cutting groove is provided on the top right side of the operating table. A slider is connected to the top right side of the operating table via a drive assembly. A cutting blade is installed at the bottom end of the slider. A material feeding trough is provided on the top right side of the operating table.
[0007] Furthermore, a drive motor is fixedly connected to the front end of the fixed block on the left, and the front end of the conveying roller on the lower side is fixedly connected to the drive end of the drive motor.
[0008] Furthermore, pulleys are fixedly connected to the front side of the outer wall of the upper conveyor roller, and the two pulleys are connected by the inner side of the belt.
[0009] Furthermore, each of the conveying rollers has a transmission gear fixedly connected to its rear side, and adjacent transmission gears are meshed together.
[0010] Furthermore, the rear ends of the conveying rollers are rotatably connected to the inner wall of the card holder, and the outer walls of the wires all penetrate the bottom of the protective shell.
[0011] Furthermore, the drive assembly includes a fixed frame fixedly connected to the right side of the top of the operating table, electric push rods fixedly connected to both the front and rear sides of the bottom end of the fixed frame, an upper frame fixedly connected to the drive end of the electric push rod, an electric slide rail fixedly connected to the inner wall of the bottom end of the upper frame, and the top of the slider is disposed on the outer wall of the electric slide rail.
[0012] Furthermore, a lower frame is fixedly connected to the bottom of the upper frame, and a through groove is provided at the top of the lower frame.
[0013] Beneficial effects:
[0014] 1. In this utility model, during the conveying process, since both the conveying roller and the card holder are made of metal, when the conveying roller rotates in the card holder inside the protective shell, the wire at the bottom of the card holder can conduct the static electricity generated by the long-term friction of the outer wall of the conveying roller to the ground, thus preventing the static electricity from adsorbing the plastic film and affecting the conveying.
[0015] 2. In this utility model, the electric push rod drive end pushes the lower frame to move downward, thereby clamping and limiting the plastic film to prevent deviation during cutting. Then, the electric slide rail can be activated to drive the slider to move, which in turn drives the cutting blade to move inside the lower cutting groove to cut the plastic film.

[0024] Please see Figures 1-3 The present invention provides an embodiment of a cutting device for processing plastic packaging bags, comprising an operating table 1, a plurality of fixed blocks 2 fixedly connected to the left side of the top of the operating table 1, two conveying rollers 4 rotatably connected to the inner walls of two adjacent fixed blocks 2, a drive motor 3 fixedly connected to the front end of the left fixed block 2, the front end of the lower conveying roller 4 fixedly connected to the drive end of the drive motor 3, pulleys 5 fixedly connected to the front side of the outer wall of the upper conveying roller 4, the two pulleys 5 being connected to each other through the inner side of the belt, transmission gears 17 fixedly connected to the rear side of the outer wall of the conveying roller 4, the two adjacent transmission gears 17 being meshed, a protective shell 6 fixedly connected to the rear end of the rear fixed block 2, a card seat 18 fixedly connected to the inner wall of the protective shell 6, a wire 19 fixedly connected to the bottom end of the card seat 18, the rear end of the conveying roller 4 being rotatably connected to the inner wall of the card seat 18, and the outer wall of the wire 19 penetrating the bottom end of the protective shell 6;
[0025] Specifically, by starting the drive motor 3, the upper conveyor roller 4 is driven to rotate. With the cooperation of the two transmission gears 17, the lower conveyor roller 4 can rotate synchronously with the upper conveyor roller 4, thereby conveying the plastic film. The pulley 5 and belt can drive the two conveyor rollers 4 on the right side to rotate together when the two conveyor rollers 4 on the left side rotate, stretching and flattening the film. During the conveying process, since both the conveyor roller 4 and the holder 18 are made of metal, when the conveyor roller 4 rotates in the holder 18 inside the protective shell 6, the wire 19 at the bottom of the holder 18 can conduct the static electricity generated by the long-term friction of the outer wall of the conveyor roller 4 to the ground, avoiding the static electricity from adsorbing the plastic film and affecting the conveying.
[0026] A lower cutting groove 12 is provided on the right side of the top of the operating table 1. A slider 14 is connected to the right side of the top of the operating table 1 via a drive assembly. The drive assembly includes a fixed frame 7 fixedly connected to the right side of the top of the operating table 1. Electric push rods 8 are fixedly connected to the front and rear sides of the bottom of the fixed frame 7. An upper frame 9 is fixedly connected to the drive end of the electric push rod 8. An electric slide rail 13 is fixedly connected to the inner wall of the bottom of the upper frame 9. The top of the slider 14 is located on the outer wall of the electric slide rail 13. A lower frame 10 is fixedly connected to the bottom of the upper frame 9. A through groove 16 is provided on the top of the lower frame 10. A cutting blade 15 is installed at the bottom of the slider 14. A material feeding groove 11 is provided on the right side of the top of the operating table 1.
[0027] Specifically, when the plastic film is conveyed to the cutting position, the electric push rod 8 is activated. The drive end of the electric push rod 8 pushes the lower frame 10 downward to clamp and limit the plastic film to prevent deviation during cutting. Then, the electric slide rail 13 can be activated to drive the slider 14 to move, which in turn drives the cutting blade 15 to move inside the lower cutting groove 12 to cut the plastic film. The cut plastic film will be directly discharged through the feeding chute 11 for collection. The lower cutting groove 12 directly penetrates the top of the operating table 1, which makes it convenient for the operator to regularly clean the dust and other impurities accumulated inside with a brush.
[0028] Working principle: In use, the plastic film is first passed between the two conveyor rollers 4. The drive motor 3 is started, and the drive end of the drive motor 3 drives the upper conveyor roller 4 to rotate. With the cooperation of the two transmission gears 17, the lower conveyor roller 4 can rotate synchronously with the upper conveyor roller 4, thereby conveying the plastic film. The pulley 5 and belt enable the two conveyor rollers 4 on the left to rotate synchronously with the two conveyor rollers 4 on the right, stretching and flattening the film. During the conveying process, the conveyor rollers 4 will rotate in the holder 18 inside the protective shell 6, locking... The wire 19 at the bottom of the seat 18 can conduct the static electricity generated by the long-term friction of the outer wall of the conveying roller 4 into the ground, so as to avoid the static electricity adsorbing the plastic film and affecting the conveying. When the plastic film is conveyed to the cutting position, the electric push rod 8 is activated. The drive end of the electric push rod 8 pushes the lower frame 10 to move downward, thereby clamping and limiting the plastic film to prevent deviation during cutting. Then, the electric slide rail 13 can be activated to drive the slider 14 to move, which drives the cutting blade 15 to move inside the lower cutting groove 12 to cut the plastic film. The cut plastic film will be directly discharged through the feeding groove 11 for collection.
