Description

Technical Field

[0001] This utility model relates to the field of woven bag sling technology, specifically a tension adjustment structure for a woven bag sling machine. Background Technology

[0002] Woven bags, also known as snake-skin bags, are a type of plastic bag used for packaging. Their raw materials are generally various chemical plastic materials such as polyethylene and polypropylene. The weaving density refers to the number of warp and weft yarns in a 100mm×100mm woven fabric. In the production process, in order to extend the service life of woven bags and for ease of use, slings are often inserted into the opening of the woven bag. The slings make it easy to tighten the woven bag, greatly increasing its practicality.

[0003] Existing tension machines for woven bag strapping typically pre-wrap the woven bag strapping material onto traction rollers for clamping. The traction rollers continuously pull the woven bag strapping material from the unwinding rollers and convey it forward. Most of these adjustment machines are quite large in size and usually use floating rollers suspended between the traction rollers, relying on the gravity of the floating rollers to generate tension on the strapping material. This method is inconvenient for different users to adjust and use, making the device rather cumbersome. In addition, since the woven bag strapping rolls are relatively loose, the woven bag strapping material on the take-up rollers is prone to loosening due to the rotational inertia of the unwinding rollers and uneven traction force, causing the woven bag to shift during conveying and affecting product quality. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a tension adjustment structure for a woven bag sling machine to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tension adjustment structure for a woven bag sling machine, comprising a fixed platform and a drive motor. Pneumatic rods are fixedly installed at both ends of the fixed platform. A connecting plate is movably installed at one end of each pneumatic rod. A guide rod is fixedly installed at one end of the fixed platform, and push plates are movably installed at both ends of the guide rod. A limit block is fixedly installed at one end of each push plate. Guide grooves that cooperate with the limit blocks are opened at both ends of the connecting plate. Limit plates are movably installed at both ends of the guide rod, and a spring is installed between the limit plates and the push plates.

[0006] By adopting the above technical solution, the limiting block installed at one end of the push plate will be limited by the guide groove, thereby causing the push plates at both ends of the guide rod to move in opposite directions along the guide rod. The push plate pushes the limiting plate through the spring, and under the action of the spring, the limiting plate limits the sling material wrapped on the floating roller and the take-up roller. This solves the problem that the sling material of the woven bag on the unwinding roller is prone to loosening due to the rotational inertia of the unwinding roller and uneven traction force, and the woven bag will deviate during the conveying process.

[0007] The present invention is further configured such that a connecting shaft is movably mounted at the output end of the drive motor, a second bevel gear is fixedly mounted at one end of the connecting shaft, a third bevel gear is movably mounted at the other end of the connecting shaft, and a guide block is fixedly mounted at one end of the connecting shaft.

[0008] By adopting the above technical solution, and by installing guide blocks, the connecting shaft limits the third bevel gear through the guide blocks, so that the rotation speed of the first traction roller and the second traction roller is synchronized during the movement of the winding roller, so that the force on the sling material is uniform and gentle during the transmission process, which is conducive to improving the product production quality.

[0009] The present invention is further configured such that a first traction roller is movably mounted on one end of the fixed platform, and a second traction roller is movably mounted on the other end of the fixed platform. A spur gear is fixedly mounted on one end of both the first and second traction rollers, and the two sets of spur gears are meshed together. A first bevel gear is fixedly mounted on one end of the second traction roller, and the first bevel gear and the second bevel gear are meshed together.

[0010] By adopting the above technical solution and installing spur gears, the first and second traction rollers can rotate synchronously, making the transportation of sling materials more stable and preventing uneven stress and damage during the transportation of sling materials.

[0011] The present invention is further configured such that a take-up roller is movably mounted on one end of the connecting plate, and a first bevel gear is also mounted on one end of the take-up roller. The first bevel gear and the third bevel gear at one end of the take-up roller are meshed together, and guide rails that cooperate with the take-up roller are provided at both ends of the fixed platform.

[0012] By adopting the above technical solution, the transmission method is made more stable by the meshing connection of the first bevel gear and the third bevel gear at one end of the winding roller, the device structure is made more perfect, and the operation is made more stable.

[0013] The present invention is further configured such that a guide plate that cooperates with the connecting plate is fixedly installed at one end of the fixed platform, and a floating roller is movably installed at one end of the fixed platform, wherein two sets of floating rollers are provided, and a sleeve shaft that cooperates with the connecting shaft is movably installed at one end of the connecting plate.

[0014] By adopting the above technical solution and installing guide plates, the connecting plates can be guided and positioned, while also providing better support for the connecting plates, thereby making the structure more stable and the linkage between structures more reasonable.

[0015] In summary, the present invention has the following main advantages:

[0016] 1. This utility model is equipped with a pneumatic rod, guide rail, guide plate, guide block, etc. The pneumatic rod extends and retracts to drive the connecting plate, so that the connecting plate moves under the limitation of the guide plate. At the same time, the connecting plate drives the winding roller to move along the guide rail, so that the third bevel gear moves synchronously with the winding roller along the connecting shaft. Meanwhile, the connecting shaft limits the third bevel gear through the guide block, so that the winding roller moves synchronously with the rotation speed of the first traction roller and the second traction roller during the movement. It also allows the operator to adjust the tension required for the production of the sling, thereby simplifying the operation steps and making it convenient for workers to use.

[0017] 2. This utility model, by setting up a connecting plate, a push plate, a limiting plate, and a spring, uses a pneumatic rod to drive the connecting plate to move. During the tension adjustment of the sling material by the movement of the connecting plate, the limiting block installed at one end of the push plate is limited by the guide groove. This causes the push plates at both ends of the guide rod to move in opposite directions along the guide rod. The push plate pushes the limiting plate through the spring, and under the action of the spring, the limiting plate limits the sling material wrapped around the floating roller and the take-up roller. This solves the problem that the woven bag sling material on the unwinding roller is prone to loosening due to the rotational inertia of the unwinding roller and uneven traction, causing the woven bag to deviate during the conveying process.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] A tension adjustment structure for a woven bag sling machine, such as Figure 1-5 As shown, the device includes a fixed platform 1 and a drive motor 5. Pneumatic rods 12 are fixedly mounted at both ends of the fixed platform 1. A connecting plate 17 is movably mounted at one end of each pneumatic rod 12. A guide rod 10 is fixedly mounted at one end of the fixed platform 1, and push plates 19 are movably mounted at both ends of the guide rod 10. A limit block 22 is fixedly mounted at one end of each push plate 19. Guide grooves 18 that cooperate with the limit blocks 22 are formed at both ends of the connecting plate 17. Limit plates 21 are movably mounted at both ends of the guide rod 10, and a spring is installed between the limit plates 21 and the push plates 19. Spring 20, through the extension and retraction of pneumatic rod 12, drives connecting plate 17, so that connecting plate 17 is limited by guide plate 14 and moves. At the same time, connecting plate 17 drives take-up roller 9 to move along guide rail 13, so that third bevel gear 16 moves synchronously with take-up roller 9 along connecting shaft 7. Meanwhile, connecting shaft 7 limits third bevel gear 16 through guide block 8, so that take-up roller 9 moves synchronously with the rotation speed of first traction roller 2 and second traction roller 3, and allows the operator to adjust the tension required for sling production.

[0027] Please see Figure 1 A connecting shaft 7 is movably mounted on the output end of the drive motor 5. A second bevel gear 15 is fixedly mounted on one end of the connecting shaft 7, and a third bevel gear 16 is movably mounted on the other end of the connecting shaft 7. A guide block 8 is fixedly mounted on one end of the connecting shaft 7. By installing the guide block 8, the connecting shaft 7 limits the third bevel gear 16 through the guide block 8, so that the rotation speed of the winding roller 9 is synchronized with that of the first traction roller 2 and the second traction roller 3 during the movement process. This makes the force on the sling material uniform and smooth during the transmission process, which is conducive to improving the product production quality.

[0028] Please see Figure 1 A first traction roller 2 is movably installed at one end of a fixed platform 1, and a second traction roller 3 is movably installed at the other end of the fixed platform 1. A spur gear 4 is fixedly installed at one end of both the first traction roller 2 and the second traction roller 3, and the two sets of spur gears 4 are meshed together. A first bevel gear 11 is fixedly installed at one end of the second traction roller 3, and the first bevel gear 11 and the second bevel gear 15 are meshed together. By installing the spur gear 4, the first traction roller 2 and the second traction roller 3 can rotate synchronously, thereby making the transportation of sling materials more stable and preventing the problem of uneven force and damage during the transportation of sling materials.

[0029] Please see Figure 3 A take-up roller 9 is movably mounted on one end of the connecting plate 17, and a first bevel gear 11 is also mounted on one end of the take-up roller 9. The first bevel gear 11 and the third bevel gear 16 at one end of the take-up roller 9 are meshed. Guide rails 13 that cooperate with the take-up roller 9 are provided at both ends of the fixed platform 1. The first bevel gear 11 and the third bevel gear 16 at one end of the take-up roller 9 are meshed, thereby making the transmission method more stable, the device structure more perfect, and the operation more stable.

[0030] Please see Figure 2 One end of the fixed platform 1 is fixedly installed with a guide plate 14 that cooperates with the connecting plate 17, and a floating roller 6 is movably installed at one end of the fixed platform 1. There are two sets of floating rollers 6. One end of the connecting plate 17 is movably installed with a sleeve shaft 23 that cooperates with the connecting shaft 7. By installing the guide plate 14, the connecting plate 17 can be guided and positioned, and at the same time, it can provide better support for the connecting plate 17, thereby making the structure more stable and the linkage between the structures more reasonable.

[0031] The working principle of this utility model is as follows: In use, the woven bag strap material is first pre-wound and clamped between the first traction roller 2 and the second traction roller 3. The strap material is then wound around the floating roller 6 and the take-up roller 9. At this time, the drive motor 5 is started, causing the drive motor 5 to drive the connecting shaft 7 to rotate. The two sets of first bevel gears 11 are driven by the meshing of the second bevel gear 15 and the third bevel gear 16. Simultaneously, the second traction roller 3 is driven by the meshing of the spur gear 4 to move the first traction roller 2 in opposite directions, and the take-up roller 9 synchronously conveys the strap material forward. Then, the pneumatic rod 12 extends and retracts to drive the connecting plate 17, causing the connecting plate 17 to move under the limitation of the guide plate 14. Simultaneously, the connecting plate 17 drives the take-up roller 9 to move along the guide rail 13, thereby causing the third bevel gear 16 to move along the connecting shaft. 7. The synchronous take-up roller 9 moves, and the connecting shaft 7 limits the third bevel gear 16 through the guide block 8, so that the take-up roller 9 moves synchronously with the rotation speed of the first traction roller 2 and the second traction roller 3, and the operator can adjust the tension required for the production of the sling. At the same time, the pneumatic rod 12 drives the connecting plate 17 to move, so that during the tension adjustment of the sling material by the movement of the connecting plate 17, the limiting block 22 installed at one end of the push plate 19 will be limited by the guide groove 18, so that the push plates 19 at both ends of the guide rod 10 move in opposite directions along the guide rod 10, so that the push plates 19 push the limiting plate 21 through the spring 20, and under the action of the spring 20, the limiting plate 21 limits the sling material wrapped on the floating roller 6 and the take-up roller 9.
