Description

Technical Field

[0001] This utility model relates to the field of setting machine technology, specifically a multi-functional adjustable needle plate setting machine for knitted fabrics. Background Technology

[0002] In the production and processing of knitted fabrics, the setting process is one of the most important steps. Its core purpose is to eliminate the internal stress generated during the fabric weaving process through heating, stretching and other methods, stabilize the fabric size, improve the appearance and physical properties of the fabric, and provide semi-finished or finished products that meet quality standards for subsequent cutting, sewing and other processes.

[0003] Currently, the industry generally uses needle plate setting machines to complete the setting process of knitted fabrics. Traditional needle plate setting machines are mainly composed of core components such as a fixed frame, rotating shaft, sprocket, chain and needle plate. Its working principle is to drive the needle plate to circulate through the chain, use the needle teeth on the needle plate to grab the edge of the fabric and drive the fabric to be conveyed at a uniform speed, and at the same time cooperate with the heating device in the setting box to achieve fabric setting.

[0004] In traditional needle plate setting machines, the needle plates are mostly fixed directly to the chain. The spacing between the needle plates or the overall installation position of the needle plates is fixed and cannot be adjusted, or can only be adjusted to a limited extent by disassembling and replacing needle plate components of different specifications. This results in the equipment only being able to adapt to knitted fabrics with a single width or a very narrow range of width. When it is necessary to process fabrics with large differences, it is necessary to stop the machine to disassemble the old needle plates and install new needle plates. This is not only cumbersome to operate and has a long changeover time, but also greatly reduces production efficiency. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] In view of the above-mentioned background technology, the existing technology has shortcomings and defects such as the spacing between needle plates or the overall installation position of the needle plate being fixed and not adjustable.

[0006] This utility model discloses a multifunctional adjustable needle plate setting machine for knitted fabrics, including a fixed frame. Rotating shafts are rotatably mounted at both ends of the fixed frame. A sprocket is mounted at both ends of each of the two rotating shafts. A chain is fitted onto the two sprockets on the same side. Needle plates are evenly mounted on the outer ring of the chain. A second sprocket is located on one side of each sprocket. A pushing component is provided between the second sprocket and the fixed frame. A second chain is fitted onto the two second sprockets on the same side. Needle plates are evenly mounted on the outer ring of the second chain. A guide is provided between the second needle plate and the first chain.

[0007] Furthermore, the guide component includes a guide plate, one end of which is mounted on the first chain, and the other end of which is disposed between the second needle plate and the second chain. The guide plate is provided with a sliding groove, and one end of the second needle plate passes through the sliding groove and is fixedly connected to the second chain. The second needle plate and the guide plate are slidably disposed.

[0008] Furthermore, the pushing component includes a sleeve and a protruding plate. The protruding plate is fixedly mounted on the rotating shaft, and the sleeve is sleeved on the rotating shaft. The sleeve is slidably disposed with respect to the rotating shaft and the protruding plate.

[0009] Furthermore, the pushing assembly also includes a connecting plate and a bidirectional ball screw. The two ends of the connecting plate are rotatably connected to the two sleeves on the same side, and the two ends of the bidirectional ball screw are rotatably mounted on the fixed frame. The bidirectional ball screw is threadedly connected to the connecting plate.

[0010] Furthermore, two bidirectional ball screws are provided, symmetrically arranged at both ends of the connecting plate. A worm gear is installed at the same end of each of the two bidirectional ball screws, and a worm is meshed on the same side of each of the two worm gears. The two worms are fixedly connected by a connecting rod, which is rotatably mounted on the fixed frame. A drive source is provided between the middle of the connecting rod and the fixed frame.

[0011] Furthermore, both the second needle plate and the guide plate are configured as "T" shapes, with one end of the second needle plate positioned between the first chain and the second chain.

[0012] Furthermore, chain tension adjustment components are provided on both sides of the fixing frame corresponding to the outer sides of chain one and chain two. Each tension adjustment component includes an adjustment bolt and a tension wheel. The tension wheel fits against the outer ring of chain one and chain two. One end of the adjustment bolt is rotatably connected to the tension wheel, and the other end is threadedly connected to the fixing frame. By turning the adjustment bolt, the tension wheel can be moved to achieve dynamic adjustment of the chain tension, thus avoiding transmission slippage or pin plate misalignment caused by wear and elongation of the chain during long-term operation.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model can drive the chain two and the needle plate two to move flexibly by pushing the component. The needle plate two can be pushed in and aligned with the needle plate one to expand the shaping width. The needle plate two can also be pulled out to allow the needle plate one to work independently. It can quickly adapt to knitted fabrics of different widths without disassembling and replacing the needle plate, shorten the production changeover time, and effectively improve the equipment's adaptability to processing fabrics of multiple specifications and overall production efficiency.

[0014] 2. Through the limiting effect of the guide component, the needle plate two can maintain smooth sliding when moving with the chain two, ensuring the alignment accuracy when it is connected with the needle plate one, and avoiding the problem of unstable fabric gripping due to misalignment of the needle plate; the tension adjustment components set on both sides of the fixed frame for the chain one and the chain two can dynamically adjust the chain tension, effectively avoiding the transmission slippage problem caused by wear and elongation of the chain during long-term operation.

[0017] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0018] Please see Figure 1 , Figure 2 The present invention relates to a multifunctional adjustable needle plate shaping machine for knitted fabrics, comprising a fixed frame 1, with rotating shafts 2 rotatably mounted at both ends of the fixed frame 1, a drive motor 19 at the power end of the rotating shaft 2, the drive motor 19 being mounted on the fixed frame 1, sprockets 3 being mounted at both ends of the two rotating shafts 2, and chains 4 being fitted onto the two sprockets 3 on the same side, with needle plates 7 evenly mounted on the outer ring of the chains 4.

[0019] See Figure 2 , Figure 3 As shown, a second sprocket 5 is provided on one side of the first sprocket 3. A pushing assembly is provided between the second sprocket 5 and the fixed frame 1. The pushing assembly includes a sleeve 11 and a convex plate 12. The convex plate 12 is fixedly installed on the rotating shaft 2. The sleeve 11 is sleeved on the rotating shaft 2, and the sleeve 11 is slidably arranged with the rotating shaft 2 and the convex plate 12. The pushing assembly also includes a connecting plate 13 and a bidirectional ball screw 14. The two ends of the connecting plate 13 are rotatably connected to the two sleeves 11 on the same side, and the two ends of the bidirectional ball screw 14 are rotatably installed on the fixed frame 1.

[0020] In this embodiment, the bidirectional ball screw 14 is made of SUJ2 high carbon chromium bearing steel and its surface is nitrided. The bidirectional ball screw 14 is threadedly connected to the connecting plate 13. There are two bidirectional ball screws 14, which are symmetrically arranged at both ends of the connecting plate 13. A worm gear 15 is installed at the same end of both bidirectional ball screws 14, and a worm 16 is meshed on the same side of both worm gears 15. The two worms 16 are fixedly connected by a connecting rod 17.

[0021] See Figure 1 , Figure 2 As shown, the connecting rod 17 is rotatably mounted on the fixed frame 1. A drive source 18 is provided between the middle of the connecting rod 17 and the fixed frame 1. The drive source 18 is a servo motor, and a planetary reducer needs to be installed at the output end. Chains 6 are fitted on the two sprockets 5 on the same side. Chain tension adjustment components are provided on both sides of the fixed frame 1 corresponding to the outer sides of chains 4 and 6. The tension adjustment components include adjustment bolts and tension wheels. The tension wheels are in contact with the outer rings of chains 4 and 6.

[0022] See Figure 2 , Figure 3 , Figure 4 As shown, one end of the adjusting bolt is rotatably connected to the tension wheel, and the other end is threadedly connected to the fixed frame 1. By turning the adjusting bolt, the tension wheel can be moved to achieve dynamic adjustment of the chain tension, thus avoiding transmission slippage or pin plate misalignment caused by wear and elongation of the chain during long-term operation. Pin plates 8 are evenly installed on the outer ring of chain 2 6. A guide is provided between pin plates 2 8 and chain 1 4. The guide includes a guide plate 9, one end of which is installed on chain 1 4.

[0023] In this embodiment, the other end of the guide plate 9 is located between the second needle plate 8 and the second chain 6. The guide plate 9 is provided with a slide groove 10, and polyurethane buffer blocks are installed at both ends of the slide groove 10. One end of the second needle plate 8 passes through the slide groove 10 and is fixedly connected to the second chain 6. The second needle plate 8 and the guide plate 9 are slidably arranged. Both the second needle plate 8 and the guide plate 9 are set in a "T" shape. One end of the second needle plate 8 is located between the first chain 4 and the second chain 6. The equipment components are cleaned regularly to avoid jamming.

[0024] The implementation principle is as follows: When needle plate 7 and needle plate 8 need to be used together, the drive source 18 is started, and the drive source 18 drives the connecting rod 17 to rotate; the connecting rod 17 drives the worm gears 16 at both ends to rotate synchronously, and the worm gears 16 mesh with the worm wheel 15 to drive the bidirectional ball screw 14 to rotate on the fixed frame 1. When the screw rotates, it drives the connecting plate 13 to move along the screw axis; the connecting plate 13 drives the sleeve 11 to slide on the rotating shaft 2, and the sleeve 11 drives the sprocket 5 sleeved on it to move synchronously. The two sprockets 5 on the same side drive the outer chain 6 to move, and at the same time the connecting plate 13 pushes the middle chain 6 to move, and the chain 6 then drives the needle plate 8 to move. As it moves, needle plate 2 8 slides smoothly along the slide groove 10, ensuring that it is eventually aligned with needle plate 2 8 and needle plate 1 7. After the width adjustment is completed, the drive motor 19 is started to drive the rotating shaft 2 to rotate. The rotating shaft 2 drives sprocket 1 3 and sprocket 2 5 to move synchronously. Sprocket 1 3 and sprocket 2 5 drive the corresponding chain 1 4 and chain 2 6 to move in a cycle. At the same time, chain 1 4 and chain 2 6 drive needle plate 1 7 and needle plate 2 8 to move. The needle teeth on needle plate 1 7 and needle plate 2 8 jointly grip the edge of the knitted fabric, driving the fabric to be conveyed at a uniform speed into the shaping box. Through heating and stretching, the internal stress of the fabric is eliminated, the fabric size is stabilized, the appearance and physical properties are improved, and the shaping process is completed.

[0025] When needle plate 7 needs to work alone, the drive source 18 of the reverse start-up component causes the connecting rod 17, worm gear 16, worm wheel 15, and bidirectional ball screw 14 to reverse the transmission, driving the connecting plate 13, sleeve 11, and sprocket 2 5 to move away from needle plate 7; chain 2 6 drives needle plate 2 8 to slide in the reverse direction along the slide groove 10 of guide plate 9, and finally pulls needle plate 2 8 out from between needle plates 7, which is suitable for processing narrow fabrics, without the need to disassemble and replace needle plates, shortening the changeover time.

[0026] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
