Description

Technical Field

[0001] This invention relates to the field of sock production equipment technology, specifically a sock turning and sewing machine. Background Technology

[0002] Socks are a type of clothing worn on the feet. With increasing market demand, socks come in a wide variety of types.

[0003] During the production of socks, the foot end needs to be sewn closed. Since the front and back of the knitted tubular sock are the same as the finished product when worn, the sock body must be turned from right to wrong before sewing. Then, the foot end of the sock body is sewn closed. After sewing, the sock is turned from wrong to right, thus completing the seam of the end.

[0004] Currently, the turning of socks is done manually, with the ends then neatly arranged before sewing, and then the socks are turned over again. This manual turning and sewing process is inefficient, and usually requires multiple people to work on this process, which increases production costs and makes it difficult to improve the production efficiency of finished socks.

[0005] A prior art document titled "An Automatic Sock Turning Device for a Sock Knitting Machine" (CN201520151099.5) is published on the China Patent Network. This prior art document includes an inlet sock tube, an outlet sock tube, a vertically arranged sleeve, and a central tube. The inlet sock tube connects to the material feeding port of the sock knitting machine. The key feature is that the lower end of the inlet sock tube is connected to the sleeve. The central tube is fixed inside the sleeve via a lower base plate and an air suction plate. The lower base plate is a solid, annular plate. The air suction plate is annular and has several ventilation holes. An annular tube with several air suction holes is provided between the lower base plate and the air suction plate. A circular hole is provided on the side wall of the sleeve for an external air suction pipe to pass through. One end of the external air suction pipe connects to the annular tube inside the sleeve, and the other end connects to a fan. The outlet sock tube is connected to the lower end of the sleeve, and a second fan is connected to the outer end of the outlet sock tube.

[0006] However, the comparative document describes a method for turning socks inside out using wind power, but this method has the following problems: First, if the socks are long or thick, insufficient wind power will prevent them from being turned inside out. Second, wind-powered turning has certain limitations; longer socks are prone to incomplete turning, causing them to bunch up and require manual turning later, making it inconvenient to use. Summary of the Invention

[0033] This invention provides a sock turning sewing machine, such as... Figure 1-9 As shown, the sock body (18) is turned inside out, including a processing cylinder 1. A connecting seat 4 is provided above the processing cylinder 1, and a hollow sleeve 5 is provided below the connecting seat 4. A connecting rod 6 is welded between the connecting seat 4 and the hollow sleeve 5. The connecting rod 6 is distributed at equal angles around the center. The connecting rod 6 overlaps at the upper opening of the processing cylinder 1, and the hollow sleeve 5 can extend into the processing cylinder 1. The sock body 18 is covered by the hollow sleeve 5.

[0034] Large electric actuators 7 are symmetrically fixed on the left and right sides of the machining cylinder 1. The large electric actuators 7 extend into the machining cylinder 1 and are welded with clamping plates 8.

[0035] The clamping plate 8 is aligned with the lower end of the sock body 18. A sewing module 10 is fixedly installed on the clamping plate 8. The sewing module 10 is used to sew the opening at the lower end of the sock body 18 closed. A clamping plate 12 is fixedly installed inside the processing cylinder 1. The clamping plate 12 is threadedly connected to a base 13. The base 13 is located directly below the hollow sleeve 5, and the base 13 and the hollow sleeve 5 are arranged in concentric circles.

[0036] Multiple rubber gaskets 14 are stacked from bottom to top on the upper end of the base 13. Moving the base 13 upwards allows the rubber gaskets 14 to be pushed into the hollow sleeve 5. An air extraction pipe 19 is connected to the upper end of the hollow sleeve 5, and the air extraction pipe 19 is connected to an air extraction device. The sewing module 10 and the air extraction device are conventional technical means, and this solution does not modify them; therefore, their specific structure and connection methods are not described in detail.

[0037] The diameter of the rubber washer 14 is the same as the inner diameter of the hollow sleeve 5. When the rubber washer 14 is pushed into the hollow sleeve 5, the edge of the rubber washer 14 abuts against the inner wall of the hollow sleeve 5. The inner diameter of the hollow sleeve 5 is the same as the inner diameter of the suction pipe 19.

[0038] Working process: The sock body 18 is placed over the hollow sleeve 5 and lowered to its lowest point along with the hollow sleeve 5. At this time, the lower end of the sock body 18 is located between the two clamping plates 8. The large electric push rod 7 extends, causing the two clamping plates 8 to clamp the sock body 18. Then, the sewing module 10 is activated to sew the lower end of the sock body 18 closed.

[0039] Next, the large electric actuator 8 is retracted, causing the clamps 8 to move away from each other. This drives the base 13 to move upward, pushing the uppermost rubber gasket 14 into the hollow sleeve 5. Since the lower end of the sock body 18 is already sewn, the rubber gasket 14 connects to the seam of the sock and is pushed into the hollow sleeve 5. Because the diameter of the rubber gasket 14 is the same as the inner diameter of the hollow sleeve 5, a negative pressure is generated inside the hollow sleeve 5 when the air extraction device extracts air, drawing the sock into the hollow sleeve 5. At this time, when the sock is drawn into the hollow sleeve 5, the sock, which was originally facing outwards, turns inwards and is eventually conveyed out along the air extraction pipe 19. This achieves the effect of turning the sock inside out.

[0040] The rubber gasket 14 acts as a piston, blocking the flow. If the rubber gasket 14 is removed, airflow can pass through the gaps in the fabric fibers, thus affecting the adsorption effect.

[0041] Support plates 15 are symmetrically welded to the left and right sides of the machining cylinder 1. The support plates 15 are located above the large electric actuator 7. A small electric actuator 16 is fixedly installed at the lower end of the support plate 15. An aluminum sheet 17 is welded to the movable end of the small electric actuator 16. The lower end of the aluminum sheet 17 extends into the machining cylinder 1. The machining cylinder 1 has holes that are adapted to the orientation of the aluminum sheet 17.

[0042] The hollow sleeve 5 has a recess 51, and an elastic sponge ring 53 is fixedly bonded to the hollow sleeve 5 within the recess 51. A rubber layer 52 is fixedly installed on the hollow sleeve 5 relative to the recess 51.

[0043] Combined with appendix Figure 3 Working process: During the sock turning process, the small electric actuator 16 is extended to bring the aluminum sheet 17 into contact with the hollow sleeve 5. At the same time, the hollow sleeve 5 is slowly pulled upward, causing the lower end of the aluminum sheet 17 to squeeze the elastic sponge ring 53, and the lower end of the aluminum sheet 17 sinks into the recess. There is a gap between the sock and the hollow sleeve 5 to facilitate the insertion of the aluminum sheet 17.

[0044] The lower end of the aluminum sheet 17 extends between the hollow sleeve 5 and the sock. As the hollow sleeve 5 continues to move, the aluminum sheet 17 acts as a barrier, promoting the sock to slowly come off.

[0045] The reason for this arrangement is that if the longer end of the sock goes into the hollow sleeve 5 and the other end goes into the hollow sleeve 5, the middle part will be stretched due to friction and suction, which will affect the turning of the sock.

[0046] The above components work together to prevent socks from being too long and thus hindering the turning of the socks inside out.

[0047] Combined with appendix Figure 4 The upper edge of the sock body 18 contacts the recess 51. A sewing area is reserved at the lower end of the sock body 18. The sewing area extends beyond the lower end of the hollow sleeve 5 and extends between the two clamps 8. When the sewing area is finished, the base 13 rises and pushes the rubber gasket 14 along with the sewn part into the hollow sleeve 5.

[0048] The clamping plate 8 has a sliding groove 81, within which a slider 9 slides. A motor 82 is fixedly mounted at the end of the clamping plate 8, and a steel wire 83 is welded to the drive shaft of the motor 82. The end of the steel wire 83 away from the motor 82 is connected to the slider 9, which is fixedly mounted to the sewing module 10. The motor 82 drives the slider 9 to move back and forth by winding the steel wire 83.

[0049] Two sliders 9 have grooves 91 on opposite sides, and buttons 92 are fixedly installed in the grooves 91. A microcontroller 93 is fixedly installed on the side of the sliders 9. Buttons 92 and microcontroller 93 are electrically connected to the sewing module 10.

[0050] During operation, the clamping plates 8 are brought together and the two sliders 9 are in contact. At this time, the buttons 92 of the sliders 9 are pressed and closed. After receiving the signal, the microcontroller 93 controls the sewing module 10 to work.

[0051] The processing cylinder 1 has a clamping hole 11, and the end of the clamping plate 12 can be clamped into the clamping hole 11. The base 13 has an external thread 131 on the outside. Two columns 121 are welded to the top of the clamping plate 12. The two columns 121 are arranged symmetrically front and back. The upper ends of the two columns 121 are symmetrically connected with welded stirrups 122. The two stirrups 122 are located on both sides of the rubber gasket 14.

[0052] The stirrups 122 provide a clamping and stabilizing effect, preventing the stacked rubber washers 14 from collapsing. When the base 13 is rotated to rise, the uppermost rubber washer 14 disengages from the stirrups 122 and is pushed into the hollow sleeve 5.

[0053] The connecting rod 6 has a hook 61 welded to its body, which engages with the upper end of the processing cylinder 1.

[0054] It also includes a frame 2, on the top of which a cylinder 3 is fixedly mounted, and the lower end of the cylinder 3 is welded to the connecting seat 4. This controls the lifting and lowering of the hollow sleeve 5.

[0055] In summary, this sock-turning sewing machine, through the cooperation of the large electric push rod 7, clamping block 8, and sewing module 10, sews the bottom of the sock closed. The base 13 rises, pushing the rubber gasket 14, along with the sock's sewn area, into the hollow sleeve 5. The sock is then sucked into the hollow sleeve 5 using a suction method, thus achieving the effect of turning the sock inside out. The aluminum sheet 17, recess 51, and rubber layer 52 work together to insert the aluminum sheet 17 between the sock and the hollow sleeve 5, assisting in separation and preventing difficulties caused by excessively long socks. This combination of components replaces the traditional wind-powered turning method, improving the success rate of sock turning, avoiding the impact of weak wind on the turning effect, and making it more convenient to use.
