Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a feeding device for a sock sewing machine. Background Technology

[0002] Sock sewing machines are textile equipment primarily used for sewing the toe area of ​​socks. Since socks are produced in a long, cylindrical shape, one end of the sock needs to be sewn together, creating an open end and a closed end to form the sock. It is one of the most important pieces of equipment in sock production, as it can improve production efficiency, and the quality of the sewing directly affects the comfort of the sock.

[0003] When operating a sock toe-sewing machine, the socks are fed through a feeding device. This device uses multiple sets of rollers to transport the socks to the desired position for sewing. However, because socks vary in length—some are knee-high socks that reach the calf, while others are ankle socks (such as boat socks)—the rollers may not reach long enough to contact the knee-high socks during feeding. This causes one end of the sock to droop and pull on the sock at the roller's position, resulting in the toe of the sock tilting and affecting the quality of the toe-sewing.

[0004] Therefore, how to provide a feeding device for a sock sewing machine is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a feeding device for a sock sewing machine. This invention solves the problem in the prior art where the roller length of the feeding device is insufficient, causing one end of the sock to droop and pull on the roller during the feeding of long socks, resulting in the sock toe tilting and affecting the quality of the sock sewing.

[0006] A feeding device for a sock sewing machine according to an embodiment of the present utility model includes a feeding platform and a feeding roller assembly, wherein the feeding roller assembly is disposed on the feeding platform;

[0007] The feeding platform is equipped with a guide assembly located on the feeding roller assembly, and the guide assembly is equipped with a movable roller unit.

The feeding roller assembly 2 is set on the feeding platform 1. The feeding roller assembly 2 is an existing stationary feeding roller assembly 2, which is fixed to the feeding platform 1 by a connecting frame.

[0026] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The feeding platform 1 is equipped with a guide assembly 3 located on the feeding roller assembly 2. The guide assembly 3 guides the movable roller unit 4. The two sets of guide rods 5 and one adjusting screw 6 are designed to be parallel to each other. The guide assembly 3 includes two sets of guide rods 5 and one adjusting screw 6. The adjusting screw 6 is set on the axis of symmetry of the feeding roller assembly 2. In this way, the movable platform 7 is subjected to balanced force during guidance. The two sets of guide rods 5 are axially symmetrical about the adjusting screw 6 as the axis of symmetry on the feeding platform 1. The guide assembly 3 also includes a movable platform 7, which is movably sleeved on the surfaces of the guide rods 5 and the adjusting screw 6. When the adjusting screw 6 is rotated, it will drive the movable platform 7 to move along the adjusting screw 6 and the guide rods 5. During operation, the adjusting screw 6 needs to be rotated first. The rotation of the adjusting screw 6 will drive the movable platform 7 to move, thereby adjusting the movable platform 7 and changing the distance between the adjusting platform and the feeding roller assembly 2.

[0027] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The guide assembly 3 is provided with a movable roller unit 4, which includes a positioning frame 8, a positioning shaft 9, and a first movable roller 10. The positioning frame 8 is fixed on the movable table 7 and moves with the movable table 7. The positioning shaft 9 is fixed on the positioning frame 8 and is used to stabilize the first movable roller 10. The diameter of the first movable roller 10 is the same as the diameter of the rollers in the feed roller group 2. The first movable roller 10 is rotatably sleeved on the surface of the positioning shaft 9 near the feed roller group 2 through a first bearing. During operation, the movement of the movable table 7 will drive the positioning frame 8 to move, the movement of the positioning frame 8 will drive the positioning shaft 9 to move, and the movement of the positioning shaft 9 will drive the first movable roller 10 to move. The movement of the first movable roller 10 realizes the adjustment of the distance between it and the feed roller group 2.

[0028] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The movable roller unit 4 further includes a secondary adjustment roller assembly 11, which includes a limiting movable hole 12, a movable tube 13, a guide shaft 14, a second movable roller 15, a drive plate 16, and a secondary adjustment component 17. The limiting movable hole 12 is located at the other end of the positioning shaft 9 away from the feeding roller assembly 2. The limiting movable hole 12 is used to limit the movable tube 13, allowing the movable tube 13 to move along the limiting movable hole 12 inside the limiting movable hole 12. Inside the hole 12, the guide shaft 14 is fixed inside the limiting movable hole 12, and the movable tube 13 is movably sleeved on the surface of the guide shaft 14. The driving plate 16 is set at a position away from the guide shaft 14 on the movable tube 13. The second movable roller 15 is fixedly sleeved on the movable tube 13. The secondary adjustment assembly 17 is set on the driving plate 16. The second adjustment assembly includes a fixed seat 18 and a secondary adjustment screw 19. The fixed seat 18 is fixed on the feed table 1, and the secondary adjustment screw 19 is rotatably connected to the fixed seat 18. The moving plate 16 is threaded onto the surface of the secondary adjusting screw 19. Here, the secondary adjusting screw 19 is located on the vertical symmetrical axis of the driving plate 16, so that the forces at both ends are balanced when the driving plate 16 moves. After the first moving roller 10 is adjusted, the secondary adjusting roller group 11 is operated. First, the secondary adjusting screw 19 is rotated, which drives the driving plate 16 to move. The movement of the driving plate 16 drives the moving tube 13 to move. The moving tube 13 moves inside the limiting moving hole 12. The movement of the moving tube 13 drives the second moving roller 15 on the moving tube 13 to move. The second moving roller 15 moves through the moving tube 13 in the limiting moving hole 12 on the guide shaft 14. In this way, the distance between the second moving roller 15 and the first moving roller 10 can be adjusted, thereby increasing the feeding width between the second moving roller 15 and the first moving roller 10. When used in conjunction with the feeding roller group 2, it can effectively feed socks of different lengths, avoiding the drooping of long socks from affecting the feeding position.

[0029] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The secondary adjustment assembly 17 also includes a transmission assembly 20, which includes a fixed bevel gear 21, a transmission bevel gear set 22, a mounting bracket 23, a guide groove 24, a guide block 25, a movable bevel gear 26, and a positioning nut 27. The fixed bevel gear 21 is fixedly sleeved on the surface of the second secondary adjustment screw 19. The guide groove 24 is formed on the surface of the adjustment screw 6. The guide block 25 is movable inside the guide groove 24. The movable bevel gear 26 is movably sleeved on the surface of the secondary adjustment screw 19 and is fixed on the surface of the guide block 25. The positioning nut 27 is movably sleeved on the side of the movable bevel gear 26 away from the feed table 1. The mounting bracket 23 is fixed on the side of the feed table 1 and the adjustment screw 6 and secondary adjustment screw 19. The lead screw 19 is offset, and the transmission bevel gear set 22 is rotatably connected to the mounting bracket 23. Both ends of the transmission bevel gear set 22 are respectively meshed with the fixed bevel gear 21 and the movable bevel gear 26. The transmission bevel gear set 22 includes two sets of identical bevel gear components 28 and a connecting rod 29. The connecting rod 29 is rotatably connected to the mounting bracket 23. The two sets of identical bevel gear components 28 are respectively fixed to both ends of the connecting rod 29, and respectively mesh with the fixed bevel gear 21 and the movable bevel gear 26. During operation, when it is necessary to move the first movable roller 10 independently, the positioning nut 27 needs to be rotated to move the positioning nut 27 away from the transmission bevel gear set 22. The movement of the adjusting screw 6 will cause the movable bevel gear 26 to move, and then move the movable bevel gear 26 away from the transmission bevel gear set 22. In this way, the rotation of the adjusting screw 6 will not drive the transmission bevel gear set 22 through the movable bevel gear 26. The rotation of the adjusting screw 6 will then drive the movable table 7 independently. This operation moves the movable bevel gear 26 independently through the movable table 7. When it is necessary to move both the first movable roller 10 and the second movable roller 15, the positioning nut 27 is rotated in the opposite direction to bring it closer to the transmission bevel gear set 22. This will engage the movable bevel gear 26 with the transmission bevel gear set 22. Then, the adjusting screw 6 is rotated again, and the rotation of the adjusting screw 6 will drive the transmission bevel gear set 22 through the movable bevel gear 26. The rotation of the transmission bevel gear set 22 will drive the rotation of the fixed bevel gear 21, which in turn will drive the rotation of the secondary adjustment screw 19. The secondary adjustment screw 19 will then drive the second movable roller 15 to move. When the second movable roller 15 needs to be moved separately, the secondary adjustment screw 19 can be rotated separately, thus realizing three sets of adjustment operations. In this way, the feeding roller set 2, the first movable roller 10, and the second movable roller 15 form a three-roller structure. The first movable roller 10 in the middle is mainly to prevent the gap between the feeding roller set 2 and the second movable roller 15 from being too large, which would cause the long stockings to droop in the middle. The movement of the first movable roller 10 and the second movable roller 15 can effectively feed stockings of different lengths.

[0030] It should be noted that the feeding platform 1, the feeding roller assembly 2, the guide assembly 3, and the movable roller unit 4 are two sets, and the two sets of feeding platform 1, feeding roller assembly 2, guide assembly 3, and movable roller unit 4 constitute a complete feeding system.
