[0003] In industry, packaging bags are used to protect manufactured parts. In the actual packaging process, the packaging bags need to be cut. However, because some parts are large, it is inconvenient for manual workers to cut the packaging bags quickly, which leads to a decrease in the packaging efficiency of the parts. Utility Model Content
[0004] To address the problem of inconvenient and slow cutting of existing packaging bags, this application provides a packaging bag cutting device.
[0005] The packaging bag cutting device provided in this application adopts the following technical solution:
[0006] A packaging bag cutting device includes a gantry and a winding assembly mounted on the gantry, and a cutting assembly connected to the winding assembly. The winding assembly includes two T-shaped sliding seats, and the same winding roller is rotatably connected between the two sliding seats. A limit component is installed on one side outer wall of one of the sliding seats. The cutting assembly is mounted on the two sliding seats and includes two connecting seats fixedly connected to the sliding seats. Multiple connecting shafts are fixedly connected to the opposite side outer walls of the two connecting seats.
[0007] By adopting the above technical solution, the winding assembly facilitates the placement of the packaging bag roll. When using the bag, the packaging bag can be pulled out directly. When the appropriate packaging bag is pulled out, it can be cut by the cutting assembly. The winding roller on the sliding seat facilitates the installation of the packaging bag roll. The setting of the limiting assembly facilitates the restriction of the rotation of the winding roller. The multiple connecting shafts on the connecting seat facilitate the guidance of the packaging bag.

[0014] The limiting assembly includes a limiting box fixedly connected to the sliding block, and a gear is rotatably connected to one inner wall of the limiting box, with one end of the gear transmission shaft fixedly connected to the take-up roller.
[0015] By adopting the above technical solution, the gear in the limit box and the take-up roller rotate coaxially, thereby facilitating the stability of the take-up roller by limiting the rotation of the gear.
[0016] A drive tube is fixedly connected to one inner wall of the limiting box, and two symmetrically arranged mounting rods are fixedly connected to the inner wall of the drive tube. Springs are sleeved on the outer walls of the two mounting rods. Two drive seats are slidably connected to the outer walls of the two mounting rods. A limiting rack that meshes with a gear is fixedly connected to one end of the drive seat. An electromagnet is fixedly connected to one inner wall of the drive tube, and an armature is fixedly connected to one outer wall of the drive seat.
[0017] By adopting the above technical solution, the electromagnet in the drive tube is energized and de-energized, and the limiting rack is adjusted by the spring to move closer to or away from the gear. The armature moves toward the electromagnet when the electromagnet is energized.
[0018] The gantry has grooves on its opposite outer walls, and electric slide rails are fixedly connected to the inner walls of the two grooves. Sliding blocks are slidably connected to the two electric slide rails, and two mounting shafts are fixedly connected to the opposite outer walls of the two sliding blocks. The two sliding seats are slidably connected to the outer walls of the two mounting rods.
[0019] By adopting the above technical solution, the height of the cutting component can be easily adjusted by the electric slide rail on the gantry, which facilitates packaging of items of different sizes. The setting of the mounting shaft facilitates the lateral adjustment of the cutting component.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. This application facilitates the cutting of packaging bags by cooperating between the winding assembly and the cutting assembly. The cooperation between the square tube and the sliding sleeve in the cutting assembly facilitates the direct cutting of the packaging bag by the cutter. Furthermore, the cooperation between the electric slide rail and the mounting shaft facilitates the adjustment of the position of the packaging bag, thereby improving the cutting efficiency of the packaging bag.
[0022] 2. This application provides a winding roller on a sliding seat, which facilitates the placement of the packaging bag roll. A limiting component is also provided on the sliding seat to limit the rotation of the winding roller and prevent the packaging bag from loosening when the winding roller shakes.

[0033] Reference Figure 2-3The winding assembly 4 includes two T-shaped sliding seats 6, and the same winding roller 7 is rotatably connected between the two sliding seats 6. A limiting component 8 is installed on one side of the outer wall of one of the sliding seats 6. The setting of the sliding seat 6 facilitates the installation of the winding roller 7, the setting of the winding roller 7 facilitates the installation of the packaging bag roll, and the setting of the limiting component 8 facilitates the limiting of the rotation of the winding roller 7.
[0034] Reference Figure 2-3 The limiting assembly 8 includes a limiting box 16 fixedly connected to the sliding block 2, and a gear 20 is rotatably connected to one inner wall of the limiting box 16. One end of the transmission shaft of the gear 20 is fixedly connected to the take-up roller 7. A drive tube 17 is fixedly connected to one inner wall of the limiting box 16, and two symmetrically arranged mounting rods 22 are fixedly connected to the inner wall of the drive tube 17. Springs 23 are sleeved on the outer walls of the two mounting rods 22. Two drive seats 18 are slidably connected to the outer walls of the two mounting rods 22. A limiting rack 19 that meshes with the gear 20 is fixedly connected to one end of the drive seat 18. An electromagnet 21 is fixedly connected to one inner wall of the drive tube 17, and an armature 24 is fixedly connected to one outer wall of the drive seat 18.
[0035] In use, the gear 20 in the limit box 16 and the take-up roller 7 rotate coaxially, thereby facilitating the stability of the take-up roller 7 by limiting the rotation of the gear 20. The on and off of the electromagnet 21 in the drive tube 17, together with the spring 23, adjusts the limit rack 19 to move closer to or away from the gear 20. The armature 24 moves toward the electromagnet 21 when the electromagnet 21 is energized.
[0036] Reference Figure 3-4 The cutting assembly 5 is mounted on two sliding seats 6, and includes two connecting seats 10 fixedly connected to the sliding seats 6. Multiple connecting shafts 11 are fixedly connected to the outer walls of opposite sides of the two connecting seats 10. A square tube 12 is fixedly connected between the two connecting seats 10, and a sliding sleeve 13 is slidably connected to the outer wall of the square tube 12. An opening is provided on one side of the outer wall of the sliding sleeve 13, and a screw hole is provided on the top outer wall of the opening. A locking bolt 15 is screwed into the inner wall of the screw hole, and a cutter 14 is engaged with the inner wall of the opening. One end of the locking bolt 15 is pressed against the cutter 14.
[0037] In use, the two connecting seats 10 facilitate the installation of the square tube 12, the square tube 12 facilitates the sliding installation of the sliding sleeve 13, and the locking bolt 15 facilitates the locking of the cutter 14, thereby facilitating the disassembly and assembly of the cutter 14.
[0038] Reference Figure 1-2The gantry 1 has sliding grooves on its opposite outer walls, and electric slide rails are fixedly connected to the inner walls of the two sliding grooves. Sliding blocks 2 are slidably connected to the two electric slide rails, and two mounting shafts 3 are fixedly connected to the opposite outer walls of the two sliding blocks 2. The two sliding seats 6 are slidably connected to the outer walls of the two mounting rods 22. The height of the cutting component 5 can be easily adjusted by the electric slide rails on the gantry 1, which facilitates the packaging of items of different sizes. The mounting shafts 3 facilitate the lateral adjustment of the cutting component 5.
[0039] The implementation principle of the packaging bag cutting device in this application embodiment is as follows: When in use, the packaging bag roll is first attached to the take-up roller 7, and then the packaging bag is passed through the connecting shaft 11 in the cutting assembly 5. When the packaging bag is needed, it is first adjusted to a suitable height by the electric slide rail, and then the sliding seat 6 is adjusted to slide on the mounting shaft 3. When it slides to the designated position, the packaging bag needs to be manually pulled to cover the item to be packaged. When the packaging bag is pulled, the electromagnet 21 in the limit box 16 is energized. When the electromagnet 21 is energized, it generates magnetism that directly attracts the armature 24 to drive the drive seat 18 to move. When the drive seat 18 moves, it directly drives the limit rack 19 away from the gear 20. At this time, the take-up roller 7 can be directly pulled to rotate. When the packaging bag is finished, the sliding sleeve 13 is slid. When the sliding sleeve 13 slides, it directly drives the cutter 14 to cut the packaging bag. During the cutting process, the electromagnet 21 is de-energized, and the limit rack 19 meshes with the gear 20 under the action of the spring 23.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
