Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, and in particular to a packaging bag slitting machine. Background Technology

[0002] Packaging bags are bags used to package various products. The production process of packaging bags includes the process of cutting a large packaging film into multiple smaller packaging films of specified sizes. This process is carried out by a slitting machine. After slitting, the smaller packaging films need to be neatly packed into multiple rolls.

[0003] For example, Chinese Patent Publication No. (CN219971384U) discloses a packaging bag slitting machine, which describes: "It includes a frame, an unwinding roller, a slitting mechanism, and a winding mechanism; the unwinding roller is rotatably mounted on the frame; the winding mechanism includes two sets of winding assemblies and a drive mechanism for driving the two sets of winding assemblies to rotate synchronously in opposite directions, the winding assembly includes a winding roller, a rotating shaft, and a driven gear, the winding roller and the driven gear are coaxially mounted on the rotating shaft, the rotating shaft is mounted on the frame, and the two driven gears in the two sets of winding assemblies are meshed together; the slitting mechanism is mounted on the frame and is located between the unwinding roller and the winding mechanism. This utility model can synchronously drive two winding rollers to wind up, and only uses one motor, reducing costs."

[0004] In summary, the device also has the following technical problems: The device effectively reduces costs by synchronously driving two winding rollers to wind up the packaging bag film. However, the winding rod is fixedly set in the middle of the machine body. Since the main function of the slitting machine is to cut the entire film and transfer it to a smaller storage component, the wound film needs to be unloaded frequently. If the traditional fixing method is used, the unloading process will be cumbersome, which will reduce the overall cutting efficiency of the device. Therefore, it is necessary to propose a packaging bag slitting machine to provide a new technical solution to solve the technical problems mentioned in the above patent. Utility Model Content

[0027] As described in the background art, the winding rod in this device is fixedly set in the middle of the machine body. Since the main function of the slitting machine is to cut the entire film and transfer it to a smaller storage component, the film that has been wound up will be unloaded frequently.

[0030] The winding mechanism 3 includes a motor bracket 5 fixedly connected to the side of the support frame 1. A geared motor 6 is fixedly connected to the surface of the motor bracket 5, and a transmission gear 7 is rotatably connected to the transmission end of the geared motor 6.

[0031] The packaging bag slitting machine provided by this utility model has a winding mechanism 3 and an arc-shaped fixed support 11 that works with an arc-shaped sliding support 13 to lock the snap-fit ​​seat 16, which can fix the central mounting shaft 15. When disassembling, the central mounting shaft 15 can be quickly disassembled by pushing the arc-shaped sliding support 13 on both sides, thereby effectively improving the efficiency of the installation and disassembly of the central mounting shaft 15.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] Example 1:

[0034] Please refer to Figures 2-5 A packaging bag slitting machine includes a support frame 1, an installation roller 2 is provided in the middle of the support frame 1, a winding mechanism 3 is provided in the middle of the support frame 1, and a tensioning and cutting mechanism 4 is provided below the winding mechanism 3.

[0035] The winding mechanism 3 includes a motor bracket 5 fixedly connected to the side of the support frame 1. A geared motor 6 is fixedly connected to the surface of the motor bracket 5, and a transmission gear 7 is rotatably connected to the transmission end of the geared motor 6.

[0036] Specifically, a drive shaft 8 is symmetrically rotatably connected to the middle of the supporting frame 1, and a driven gear 9 is fixedly connected to the surface of the drive shaft 8 near the geared motor 6. The driven gear 9 meshes with the drive gear 7.

[0037] Specifically, a side plate 10 is fixedly connected to one end of the drive shaft 8 near the inside of the support frame 1, and an arc-shaped fixed support seat 11 is fixedly connected to the side of the side plate 10 away from the drive shaft 8. A guide groove 12 is provided inside the arc-shaped fixed support seat 11.

[0038] Specifically, the side plate 10 is slidably connected to an arc-shaped sliding support 13, and the bottom surface of the arc-shaped sliding support 13 is fixedly connected to a guide block 14. The guide block 14 is slidably disposed inside the guide groove 12, and a return spring 19 is disposed inside the guide groove 12.

[0039] Specifically, a central mounting shaft 15 is provided in the middle of the supporting frame 1, and two ends of the central mounting shaft 15 are respectively fixedly connected to snap-fit ​​seats 16. The surface of the snap-fit ​​seat 16 is provided with snap-fit ​​grooves 18. A snap-fit ​​block 17 is fixedly connected in the middle of the arc-shaped fixed support seat 11. The snap-fit ​​block 17 snaps into the middle of the snap-fit ​​groove 18.

[0040] Specifically, a tension rod 22 is provided in the middle of the support frame 1, and a cutting disc is connected to the surface of the tension rod 22.

[0041] With the above structural design, when using the device, first pass the film through the bottom of the tension rod 22 and install the film onto the corresponding storage component on the surface of the central mounting shaft 15. After completion, turn on the reduction motor 6. The reduction motor 6 drives the driven gear 9 to rotate through the transmission gear 7. At the same time, the driven gear 9 rotates through the transmission shaft 8 to drive the central mounting shaft 15 in the middle to rotate, thereby realizing the winding of the cut film. After winding, turn off the reduction motor 6. At this time, push the arc-shaped sliding support seats 13 on both sides outward in sync. While the arc-shaped sliding support seats 13 move, drive the bottom guide block 14 to slide inside the guide groove 12. While the guide block 14 slides, it squeezes and contracts the reset spring 19. After the arc-shaped sliding support seats 13 are removed from the top of the snap-fit ​​seat 16, the snap-fit ​​seat 16 can be removed from the middle of the arc-shaped fixed support seat 11 in conjunction with the central mounting shaft 15.

[0042] During installation, simply push the arc-shaped sliding support 13 to both sides. After that, align the snap-fit ​​groove 18 on the surface of the snap-fit ​​seat 16 with the snap-fit ​​block 17 and snap it into the middle of the snap-fit ​​groove 18. After that, release the arc-shaped sliding support 13. At this time, the return spring 19 pushes the guide block 14 to cause the arc-shaped sliding support 13 to press and fix the snap-fit ​​seat 16, thereby realizing the quick installation of the center mounting shaft 15.
