Abstract
Description
Technical Field
[0001] This utility model relates to the field of film slitting machine technology, and in particular to a packaging bag film slitting machine that eliminates static electricity and prevents adhesion. Background Technology
[0002] A film slitting machine is a mechanical device used to cut wide film materials into multiple narrow strips. It is widely used in packaging, lamination and other industries and can process various types of film materials.
[0003] When a film slitting machine is slitting, the cutter will stick to the slitting film due to electrostatic adsorption. The lack of an effective electrostatic elimination structure and limiting and coordinating structure will cause the film to shift due to electrostatic adsorption, and there will be gaps at the bottom of the film. When the cutter descends, it may cause the cutting position to shift, resulting in a decrease in slitting accuracy and affecting subsequent production operations and product quality. Utility Model Content
[0004] This utility model discloses a packaging bag film slitting machine that eliminates static electricity and prevents adhesion, aiming to solve the technical problem that if the cutter and film are not effectively eliminated and limited, the film will shift due to static adsorption, and the cutting position will shift due to the film not adhering properly, resulting in a decrease in slitting accuracy.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A packaging bag film slitting machine for eliminating static electricity and preventing adhesion includes a support frame. Two mounting frames are fixedly connected to the top of the support frame. A common mounting frame is fixedly connected to the top of the two mounting frames. Two hydraulic rods are fixedly connected to the mounting frame, and a common mounting base is fixedly connected to the drive ends of the two hydraulic rods. A cutter is fixedly connected to the bottom of the mounting base. A working module is provided on the mounting base, and the working module includes two symmetrically arranged pressing seats. A common auxiliary module is provided on the two pressing seats. The working module also includes two symmetrically arranged movable plates. The two pressing seats are fixedly connected to corresponding movable plates. The two movable plates slide on opposite sides of the mounting base, and are equidistantly connected for rotation. The mounting base is equipped with rotating frames, each containing an ion gun. A connecting frame is fixedly connected to one side of each rotating frame, and toothed rings are fixedly connected to the outside of each connecting frame. Multiple racks are fixedly connected at equal intervals to the opposite outer walls of the mounting base, and each rack meshes with a corresponding toothed ring. Fixed plates are fixedly connected to the opposite outer walls of the mounting base. Each fixed plate has two circular holes, and two limiting rods are fixedly connected to the top of each movable plate. These limiting rods slide within their respective circular holes. Springs are fixedly connected to the outside of each limiting rod, with one end of each spring fixedly connected to a fixed plate and the other end fixedly connected to a movable plate.
[0007] With an operational module, when the mounting base descends, the two pressure seats first press down on the film on both sides of the slitting section, activating the ion gun to eliminate static electricity at the cutter. As the mounting base continues to descend, the pressure seats push the movable frame to compress the springs and slide outside the mounting base. The cutter continues to descend with the mounting base to complete the slitting. Simultaneously, through the meshing of the rack and toothed ring, the rack meshes with and rotates the rotating seat as the mounting base moves down, so that the output angle of the ion gun roughly follows the position of the cutter until the slitting is complete. When the mounting base rises, the pressure seats continue to press down on the film under the elastic action of the springs until the mounting base rises to a certain height. The output angle of the ion gun follows the cutter, which can continuously neutralize static electricity on the cutter and the slitting section, effectively suppressing the phenomenon of static adsorption of the film. At the same time, the pressure seats can position and press the film to keep it in place, avoiding gaps at the bottom of the film that would affect the slitting accuracy. When the cutting is completed, the pressure seats are lifted after a delay, further ensuring the smooth separation of the film from the cutter section after slitting.
[0008] In a preferred embodiment, the auxiliary module includes two air pumps, both of which are fixedly connected to the outside of their respective lower pressure seats. A diverter pipe is fixedly connected to the outside of each of the two lower pressure seats. The output ends of both air pumps are connected to their respective diverter pipes. Multiple nozzles are equidistantly opened on both lower pressure seats. Multiple connecting pipes are fixedly connected to both diverter pipes, with the ends of the connecting pipes furthest from the diverter pipes connected to their respective nozzles. Multiple mounting holes are equidistantly opened on both mounting frames. A common drive roller is rotatably connected to each of the corresponding two mounting holes. A common conveyor belt is connected to the outside of the multiple drive rollers. Drive wheels are fixedly connected to the outside of the multiple drive rollers. A common drive belt is connected to the outside of the multiple drive wheels. A drive motor is fixedly connected to one side of one of the mounting frames, and the output end of the drive motor is fixedly connected to the corresponding drive roller.
[0009] With the auxiliary module in place, when the lower pressure seat is raised, the air pump is activated to pump air into the nozzle through the split pipe and connecting pipe. The airflow assists in separation, avoiding the adsorption force between the lower pressure seat and the diaphragm due to local vacuum, and preventing the diaphragm from being lifted by the lower pressure seat.
[0010] As can be seen from the above, the packaging bag film slitting machine provided by this utility model has an ion air gun output angle and a follow-up cutter, which continuously neutralizes static electricity on the cutter and the slitting part, effectively suppressing the phenomenon of static adsorption of film. At the same time, the lower pressure seat can position and press the film to keep the film adhered, avoiding gaps at the bottom of the film that affect the slitting accuracy. When the cutting is completed, the lower pressure seat is lifted after a delay, further ensuring the smooth separation of the film from the cutter part after slitting. Attached Figure Description

The working module 5 also includes two symmetrically arranged movable plate frames 502. The two pressing seats 510 are fixedly connected to the corresponding movable plate frames 502. The two movable plate frames 502 slide on opposite sides of the mounting seat 7, and rotating frames 506 are rotatably connected to each movable plate frame 502 at equal distances. Each rotating frame 506 has an ion gun 507 fixedly connected inside. Each rotating frame 506 has a connecting frame 508 fixedly connected to one side. Each connecting frame 508 has a toothed ring 509 fixedly connected to its exterior. Each of the opposite outer walls of the mounting base 7 has a toothed rack 505 fixedly connected at equal intervals, and each toothed rack 505 meshes with its corresponding toothed ring 509. Each of the opposite outer walls of the mounting base 7 has a fixed plate frame 501 fixedly connected to its exterior. Each fixed plate frame 501 has two round holes.

[0019] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the auxiliary module 6 includes two air pumps 602, both of which are fixedly connected to the outside of a corresponding lower pressure seat 510. A diverter pipe 603 is fixedly connected to the outside of each of the two lower pressure seats 510. The output ends of both air pumps 602 are connected to the corresponding diverter pipes 603. Multiple nozzles 601 are equally spaced on each of the two lower pressure seats 510, and multiple connecting pipes 604 are fixedly connected to each of the two diverter pipes 603. The ends of the multiple connecting pipes 604 furthest from the diverter pipes 603 are... The two mounting frames 2 are connected to the corresponding ejection holes 601. Multiple mounting holes are equally spaced on both mounting frames 2. The same transmission roller 9 is rotatably connected in each of the two corresponding mounting holes. The external transmission rollers 9 are connected to the same conveyor belt 13. The external transmission rollers 9 are fixedly connected to the transmission wheels 10. The external transmission wheels 10 are connected to the same transmission belt 11. A drive motor 12 is fixedly connected to one side of one of the mounting frames 2. The output end of the drive motor 12 is fixedly connected to the corresponding transmission roller 9.
[0020] Working principle: The drive motor 12 is started, causing the transmission roller 9 connected to its output end to rotate. This transmission roller 9 then drives the transmission wheel 10 to rotate, which in turn drives the remaining transmission rollers 9 to rotate via the transmission belt 11. The synchronous rotation of multiple transmission rollers 9 drives the conveyor belt 13 to move, transporting the film. Once the film reaches the designated position, it stops. The hydraulic rod 4 extends, pushing the mounting base 7 downwards. The lower pressure seat 510 first contacts the film, using two lower pressure seats 510 to press down the film on both sides of the slitting section. The ion gun 507 is activated to eliminate static electricity at the cutter 8. As the mounting base 7 continues to descend, the lower pressure seat 510 pushes the movable plate frame 502 to compress the spring 504, causing it to slide outside the mounting base 7. The cutter 8 continues to descend with the mounting base 7, completing the slitting process. Simultaneously, through the meshing of the rack 505 and the toothed ring 509, the rack 505 meshes with the rotating seat as the mounting base 7 moves downward, so that the output angle of the ion air gun 507 roughly follows the position of the cutter 8 until the cutting is completed, effectively overcoming the electrostatic adsorption effect between the film and the blade; the retraction of the hydraulic rod 4 first drives the mounting base 7 and the cutter 8 to rise, and the lower pressure seat 510 continues to press down on the film under the elastic action of the spring 504 until the mounting base 7 rises to a certain height. At the same time, the air pump 602 is started to pump air into the spray hole 601 through the split pipe 603 and the connecting pipe 604. Through airflow-assisted separation, the adsorption force generated between the lower pressure seat 510 and the film due to local vacuum is avoided, preventing the film from being lifted by the lower pressure seat 510.
