Description

Technical Field

[0001] The utility model relates to the field of film changing machines, and particularly relates to an automatic film changing machine for producing plastic bags. Background Technique

[0002] Plastic bags are generally formed by hot melting and pressing two upper and lower films. The inner side of each film is usually a PE material surface, and the outer side is a PA material surface. Utilizing the hot melt welding property of PE is convenient for hot melting and pressing the upper and lower films. After the film production and winding are completed, it is generally necessary to stop the machine. After manually replacing the new film winding shaft at the working position, the machine can be restarted for production. Therefore, it is necessary to stop and wait, resulting in low production efficiency.

The driving assembly is fixedly connected to the feeder body 1.

[0021] In this embodiment, a moving groove 12 is opened at the lower end of the feeder body 1. Two guide rods 11 are fixedly connected to the inside of the moving groove 12. Two sliders are fixedly connected to the lower end of the moving plate 2. The guide rods 11 are slidably connected to the moving plate 2 through the sliders. A lead screw 10 is rotatably connected to the inside of the moving groove 12. The lead screw 10 is threadedly connected to the moving plate 2. A knob 9 is fixedly connected to the rear end of the lead screw 10.

[0022] Specifically, through the cooperation of the guide rod 11 and the lead screw 10, the moving of the moving plate 2 can be facilitated.

[0023] In this embodiment, the clamping mechanism 8 includes a pull rod 81. The pull rod 81 is slidably connected to the clamping mechanism 8. A fixed plate 82 is fixedly connected to the outside of the pull rod 81. A spring 83 is fixedly connected to the lower end of the fixed plate 82. The lower end of the spring 83 is fixedly connected to the first turntable 7. The spring 83 is sleeved on the outside of the pull rod 81. A limiting hole is opened on the outside of the connecting rod 6. The pull rod 81 is adapted to the limiting hole.

[0024] Specifically, through the cooperation of the spring 83 and the fixed plate 82, the pull rod 81 can conveniently limit the connecting rod 6.

[0025] In this embodiment, the driving assembly includes a driving motor 13 and an electric telescopic rod 16. The output end of the driving motor 13 is fixedly connected to a rotating shaft 18. The rear end of the rotating shaft 18 is fixedly connected to a plug pin 19. The plug pin 19 is adapted to the winding shaft 61. The lower end of the driving motor 13 is fixedly connected to a bracket 14. Two sets of sliding grooves are provided at the lower end of the bracket 14.

[0030] Specifically, through the limitation of the limiting roller 4, it can ensure that the thickness of the film wound by the winding roller 5 is consistent. When the film touches the sensing mechanism on the limiting roller 4, the sensing mechanism will control the driving motor 13 to stop working and start the electric telescopic rod 16 to contract. At this time, the film wound on the winding shaft 61 will rotate downward under the action of gravity. At this time, the spare winding shaft 61 on the second turntable 71 will rotate to the position driven by the driving motor 13 for winding. At this time, the electric telescopic rod 16 will drive the driving motor 13 to move and connect with the winding shaft 61, thus realizing automatic material change of the winding shaft 61, reducing the waiting time required for manual material change and improving production efficiency.

[0031] It should be noted that the present utility model is an automatic film feeding machine for producing plastic bags. The user installs the winding roller 5 on the first turntable 7. At this time, rotate the knob 9. The rotation of the knob 9 will drive the lead screw 10 to rotate. Through the cooperation of the guide rod 11, the moving plate 2 can be moved. The movement of the moving plate 2 will drive the first turntable 7 to move so as to adapt to the size of the winding roller 5, thus realizing that a feeding rack can be applicable to the use of winding rollers 5 of various sizes at the same time, improving the practicability. At this time, start the driving motor 13. The rotation of the driving motor 13 will drive the winding shaft 61 to rotate. The rotation of the winding shaft 61 will drive the winding roller 5 to rotate so as to realize the winding of the film. When the film touches the sensing mechanism on the limiting roller 4, the sensing mechanism will control the driving motor 13 to stop working and start the electric telescopic rod 16 to contract. The contraction of the electric telescopic rod 16 will drive the connecting block 17 to move. The movement of the connecting block 17 will drive the bracket 14 to move, thus realizing that the driving motor 13 drives the rotating shaft 18 and the plug 19 to be separated from the winding shaft 61. At this time, the film wound on the winding roller 5 will rotate downward under the action of gravity. At this time, the spare winding shaft 61 on the second turntable 71 will rotate to the position driven by the driving motor 13. At this time, the electric telescopic rod 16 will drive the driving motor 13 to move and be connected with the winding shaft 61, thus realizing the automatic feeding of the winding shaft 61, reducing the waiting time required for manual feeding and thus improving the production efficiency, which is relatively practical.
