Description

Technical Field

[0001] This utility model relates to the field of bag cutting technology in the production of FIBCs (Flexible Intermediate Bulk Containers), specifically to a special-shaped bag cutting machine for the production of FIBCs. Background Technology

[0002] FIBCs, also known as bulk packaging bags, ton bags, flexible container bags, space bags, etc., are large bags used for storing and transporting dry bulk goods such as sand, fertilizer, grain, etc.

[0003] The current announcement number CN216267868U discloses a special-shaped bag cutting machine for the production of FIBCs (Flexible Intermediate Bulk Containers), including a base, a placement frame, and a fixing frame. The placement frame is fixedly connected to the upper right side of the base, and a clamp is attached to the upper side of the placement frame. The bottom left side of the clamp is rotatably connected to the upper left side of the placement frame via a hinge. The placement frame is set at both ends of the take-up roller. Rotating sleeves are sleeved at both ends of the take-up roller. The rotating sleeves are rotatably connected to the take-up roller. The take-up roller is slidably connected to the upper end of the placement frame and to the bottom end of the clamp. This utility model can fix the rotating sleeves through the placement frame and the clamp, thereby facilitating the quick replacement of the take-up roller. In addition, with the second spring and the push block, the extrusion roller can squeeze the take-up roller, increasing the stability of the take-up roller during rotation and preventing material protrusion on the take-up roller.

[0004] To address the issues in FIBC production, existing technologies employ placement racks and clamps to fix the rotating sleeve. However, this method still fails to limit the movement of materials on both sides, leading to material deviation during transport and reduced cutting accuracy. Utility Model Content

[0030] The present invention will be further described in detail below with reference to embodiments: Example

[0031] like Figure 1-5 As shown, this utility model provides a special-shaped bag cutting machine for the production of container bags, including a mounting frame 1, a placement unit 2 and a tensioning unit 3 on the inner side of the mounting frame 1, a limiting unit 4 inside the mounting frame 1, and a dust removal unit 5 on the outer side of the mounting frame 1. The limiting unit 4 includes a rotating roller 41, which is rotatably connected to the inside of the mounting frame 1. A motor 42 is fixedly connected to one side of the rotating roller 41. A bidirectional threaded rod 43 is fixedly sleeved at the output end of the motor 42. A limiting block 44 is threadedly connected to the inner side of the bidirectional threaded rod 43. The inner side of the limiting block 44 is slidably connected to the inner side of the rotating roller 41. A rotating wheel 45 is rotatably connected to one side of the limiting block 44. The motor 42 is controlled to rotate, which in turn drives the limiting block 44 inside the bidirectional threaded rod 43 to move inside the rotating roller 41. At the same time, the rotating wheel 45 is used to fit against both sides of the material, thereby limiting the material and fixing one end of the material inside the winding assembly. Example

[0032] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the placement unit 2 includes a fixing frame 21, which is fixedly connected to the inner side of the mounting frame 1. A limiting roller 22 is rotatably connected inside the fixing frame 21. A fixing frame 23 is provided on one side of the fixing frame 21. A clamping frame 24 is rotatably connected inside the fixing frame 23. A supporting telescopic rod 25 is rotatably connected to one side of the clamping frame 24. A spring 26 is fixedly connected to one side of the supporting telescopic rod 25. One end of the spring 26 is fixedly connected to one side of the clamping frame 24. A fixing frame 27 is rotatably connected to one side of the supporting telescopic rod 25. A supporting roller 28 is rotatably connected inside the clamping frame 24. By placing the material roll for the production of the container bag on the top surface of the limiting roller 22 and adhering it to both sides of the roll through the supporting roller 28, the clamping frame 24 on one side of the supporting roller 28 moves due to its own gravity. At the same time, through the cooperation of the supporting telescopic rod 25 and the spring 26, the supporting roller 28 supports both sides of the roll. Example

[0033] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the tensioning unit 3 includes an electric telescopic rod 31, which is fixedly connected to the top surface of the mounting frame 1. A movable frame 32 is fixedly connected to the telescopic end of the electric telescopic rod 31. A guide frame 33 is rotatably connected to one side of the movable frame 32. A spring 34 is rotatably connected to the inner side of the guide frame 33. A tensioning roller 35 is fixedly connected inside the guide frame 33. The dust removal unit 5 includes a dust removal box 51, which is fixedly connected to one side of the mounting frame 1. A fan 52 is sleeved inside the dust removal box 51. A filter screen 53 is provided inside the dust removal box 51. A suction pipe 54 is sleeved inside the dust removal box 51. A movable plate 55 is fixedly connected to the inner side of one end of the suction pipe 54. A filter screen 53 is provided inside the movable plate 55. The cutting assembly 56 has one end of the moving plate 55 slidably connected to the inside of the mounting frame 1. The cutting assembly 56 has a threaded rod 57 threadedly connected inside. One end of the threaded rod 57 is fixedly connected to a motor 58. Simultaneously, the electric telescopic rod 31 is controlled to drive the moving frame 32 to move downward, thereby causing the spring 34 to contact one side of the material roll. The spring 34 contacts one side of the material, and the elastic action of the tension roller 35 keeps the material in a tensioned state. At the same time, the motor 58 is controlled to drive the threaded rod 57 to move, adjusting the cutting position, thereby controlling the cutting assembly 56 to cut the material. Simultaneously, the fan 52 is controlled to transport the debris generated during cutting through the dust suction pipe 54 to the inside of the dust collection box 51, where it is filtered and collected by the filter screen 53.

[0034] The working principle of this irregular bag cutting machine used for the production of FIBCs will be explained in detail below.

[0035] like Figure 1-5 As shown, the material roll for bulk bag production is placed on the top surface of the limiting roller 22 and then bonded to both sides of the roll by the support roller 28. The material roll's own weight causes the clamping frame 24 on one side of the support roller 28 to move. Simultaneously, the support roller 28 supports both sides of the roll through the cooperation of the support telescopic rod 25 and spring 26. At the same time, the motor 42 rotates, causing the limiting block 44 inside the bidirectional threaded rod 43 to move inside the rotating roller 41. Simultaneously, the rotating wheel 45 bonds to both sides of the material, thus limiting the material's position and setting one end of the material... Fixed inside the winding assembly, the electric telescopic rod 31 is controlled to drive the moving frame 32 downward, thereby causing the second spring 34 to contact one side of the material roll. The second spring 34 contacts one side of the material, and the elastic action of the tension roller 35 keeps the material in a tensioned state. At the same time, the second motor 58 is controlled to drive the threaded rod 57 to move, adjusting the cutting position. Then, the cutting assembly 56 is controlled to cut the material. At the same time, the fan 52 is controlled to transport the debris generated by cutting through the dust suction pipe 54 to the inside of the dust collection box 51, where it is filtered and collected by the filter screen 53.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
