Description

Technical Field

[0001] The utility model belongs to the technical field of tightening equipment, and specifically refers to a winding tension control device for bag-making processing. Background Technique

[0002] Packaging bags are manufactured by a bag-making machine. A bag-making machine is a machine for making various plastic packaging bags or packaging bags made of other materials. Its processing range includes plastic or other material packaging bags of various sizes, thicknesses, and specifications, generally with plastic packaging bags as the main product.

[0003] When the bag-making machine is in production, generally a roll of film for making packaging bags is placed on the unwinding roller. The film passes through the guiding device and enters the heat-sealing and cutting area for processing and forming. Since it takes a certain amount of time for heat-sealing and cutting, the film advances intermittently during operation. When heat-sealing and cutting are in progress, the film stops being transported, but the unwinding roller will continue to rotate for a certain period due to inertia, which will cause the film to become loose, thereby affecting the production and processing efficiency of packaging bags. Content of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a winding tension control device for bag-making processing, which is used to solve the problem that the film becomes loose due to the inertial rotation of the unwinding roller in the prior art.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0026] As Figures 1-4 shown, a winding tension control device for bag making processing of the present utility model includes a frame 1, a feeding roller 2 and a winding roller 3. The feeding roller 2 and the winding roller 3 are respectively rotatably arranged on both sides of the frame 1.

[0027] This embodiment further includes a driving shaft 4 and a tension adjusting device 5. The driving shaft 4 is rotatably arranged between the two sides of the frame 1. The tension adjusting device 5 is arranged between the frames 1. The tension adjusting device 5 is arranged below the driving shaft 4. A driving motor 534 is arranged on one side of the frame 1 outside the driving shaft 4. The output shaft of the driving motor 534 is connected to the driving shaft 4. The output shaft of the driving motor 534 drives the driving shaft 4 to rotate, thereby realizing the driving of the bag film.

[0028] Referring to Figure 1 and Figure 4 shown, the tension adjusting device 5 includes an adjusting shaft 51, an adjusting seat 52 and an adjusting component 53. The adjusting shaft 51 is rotatably arranged between the two sides of the frame 1, and the adjusting shaft 51 is arranged below the driving shaft 4. The adjusting seat 52 is arranged on one side of the frame 1. A thread adjustment hole 531 is opened on the adjusting seat 52. Adjusting accessories 532 are arranged on both sides of the adjusting shaft 51. The adjusting component 53 passes through the thread adjustment hole 531 of the adjusting seat 52 and is fixed to the adjusting accessory 532, thereby adjusting the horizontal position of the adjusting shaft 51. And among them, the horizontal position of the adjusting shaft 51 is set higher than that of the feeding roller 2.

[0029] Referring to the drawings, the frame 1 is arranged in a triangular shape. The feeding roller 2 and the winding roller are horizontally arranged on both sides of the bottom of the frame 1. The driving shaft 4 is arranged on one side of the top of the frame 1. And the driving shaft 4, the feeding roller 2 and the winding roller form an isosceles triangle. The film passes above the winding roller 3, below the adjusting shaft 51, winds around the outer top of the driving shaft 4, and then passes through the outer circumference of the unwinding roller, forming a Z-shaped transfer during the film transmission.

[0030] Among them, the adjusting component is a threaded rod, which meshes with the threaded adjusting hole 531. A fixing hole 533 is provided on the adjusting accessory 532, and the other end of the threaded rod is inserted into the fixing hole 533. The adjusting accessory 532 is rotatably connected to the adjusting shaft 51 through a bearing.

[0031] In a further embodiment, printing protrusions with printing and anti-slip functions can be provided on the unwinding roller 2 and the winding roller 3 as required.

[0032] Before using the present utility model, since a fixing member 535 is provided at the side end of the frame 1, and a support shaft is provided on the inner wall of the fixing member 535 with respect to the frame 1, the fixing member 535 is used to fix the frame 1 on the associated processing equipment.

[0033] When using the present utility model, through the setting of the tension adjusting device 5, a zigzag transfer is formed during the film transmission. By using the adjusting shaft 51 whose height can be adjusted, the size of the tension is adjusted. The threaded rod with a handle at the top meshes with and penetrates through the threaded adjusting hole 531 of the adjusting seat 52 and is fixed to the adjusting accessory 532, thereby adjusting the horizontal position of the adjusting shaft 51, and the tension of the film can be increased as required, which is used to solve the situation that the film is slack caused by the inertial rotation of the unwinding roller in the prior art.

[0034] As another embodiment, adjusting accessories 532 and adjusting components can also be provided outside the unwinding roller 2 and the winding roller 3. Different from the adjusting shaft 51, the side end of the adjusting accessory 532 of the adjusting shaft 51 is open, while the adjusting accessories 532 of the unwinding roller 2 and the winding roller 3 are open at the top, converting the change in the horizontal position into the adjustment of the height position, and further enhancing the tensioning force.

[0035] It should be noted that although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
