Description

Technical Field

[0001] This utility model belongs to the field of sock knitting machine technology, and in particular relates to a jumper device for sock knitting machines. Background Technology

[0002] A sock knitting machine is an industrial piece of equipment that uses computer numerical control technology to knit and manufacture cotton socks. It can produce socks with a variety of styles and meticulous details. The skipping device is a mechanical device in a sock knitting machine used to control the jumping motion of the needles during the knitting process, and it plays a vital role in the sock knitting machine.

[0003] However, in actual applications, when the jumper needle moves within the groove on the adjustment plate, it is easy for it to come into contact with the inner wall of the groove. Since the adjustment plate is stationary, the contact between the jumper needle and the adjustment plate can easily generate dry friction, which can cause wear on the jumper needle and affect its service life. There is a technical problem that it is not possible to provide anti-friction pads to ensure the normal jumping and resetting motion of the jumper needle, thereby ensuring its service life and reducing the cost of using the device. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a jumper device for a sock knitting machine, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a skipping needle device for a sock knitting machine, comprising a frame, and further comprising: a main shaft passing through one side between the two ends inside the frame, a rotating seat being provided outside the main shaft, an adjusting plate being provided on one side of the top of the frame, a limiting groove being provided on the top of the adjusting plate, a skipping needle being provided on one side of the rotating seat, a fixing frame being provided outside the limiting groove on one side of the adjusting plate, a bottom stabilizing shaft being rotatably connected to the bottom between the two ends inside the fixing frame, a side stabilizing shaft being rotatably connected to the two ends of the top inside the fixing frame, a first rubber sleeve being provided outside the side stabilizing shaft, a second rubber sleeve being provided outside the bottom stabilizing shaft, and limit components being provided outside the main shaft at both ends of the rotating seat.

[0007] Furthermore, the fixing frames are arranged at equal intervals on one side of the adjusting plate, and the side stabilizing shafts are symmetrically arranged at the top inside the fixing frames, with the side stabilizing shafts perpendicular to the bottom stabilizing shafts.

[0008] Furthermore, a cylinder is installed on the top of one side of the frame, and multiple sets of cylinders, jumper needles, tension springs, rotating seats, and adjusting seats are provided. A metal plate is installed on the top of one side of the inside of the frame, a wire break contact is installed on the top of the rotating seat, a tension spring is hung on the bottom of one side of the rotating seat, an adjusting seat is installed on one side of the bottom of the inside of the frame, a wire inlet frame is installed on one side of the bottom of the frame, and a lead wire is installed on one side of the jumper needle.

[0009] Furthermore, one side of the tension spring is hooked to the top of the adjusting seat, and multiple sets of limiting grooves are provided. The limiting grooves are arranged at equal intervals on the top of the adjusting plate, and the jumper needle passes through the interior of the limiting groove.

[0010] Furthermore, the limiting component includes a stabilizing seat, which is disposed outside the main shaft at both ends of the rotating seat. The stabilizing seat has a groove inside, and a limiting ball is embedded inside the groove. The limiting ball is coated with a wear-resistant coating.

[0011] Furthermore, the stabilizing seat is annular, multiple sets of the limiting balls are arranged in the groove, and the wear-resistant coating is uniformly distributed on the outside of the limiting balls.

[0012] This utility model has the following beneficial effects:

[0013] This invention features a protective component on the outer side of the limiting groove on one side of the adjusting plate. When the jumper needle reciprocates and resets under the action of the tension spring and cylinder, it moves within the limiting groove. The bottom stabilizing shaft and the side stabilizing shaft rotate accordingly, preventing dry friction between the jumper needle and the inner wall of the limiting groove, thus avoiding wear. Furthermore, when the jumper needle contacts the outer side of the bottom stabilizing shaft and the side stabilizing shaft, the first and second rubber sleeves protect the contact surface, thereby preventing wear on the jumper needle by the bottom stabilizing shaft and the side stabilizing shaft. This effectively protects the jumper needle in the device, extends its service life, and reduces the cost of using the device.

[0014] This invention provides limiting components on the outside of the main shaft at both ends of the rotary seat. When the rotary seat rotates outside the main shaft, it is fixed in a fixed position outside the main shaft by the stabilizing seat, which prevents the rotary seat from moving axially outside the main shaft and causing the device to malfunction. At the same time, the limiting ball can roll in the groove as the rotary seat rotates, which achieves the purpose of stabilizing the rotary seat while avoiding friction between its side and the inside of the stabilizing seat. In addition, the wear-resistant coating makes the contact surface between the limiting ball and the rotary seat more wear-resistant. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4As shown, this utility model is a skipping needle device for a sock knitting machine, including a frame 1, and further including: a main shaft 8 passing through one side between the two ends inside the frame 1, a rotating seat 4 being provided outside the main shaft 8, an adjusting plate 10 being provided on one side of the top of the frame 1, a limiting groove 13 being provided on the top of the adjusting plate 10, multiple sets of limiting grooves 13 being provided, and the limiting grooves 13 being arranged at equal intervals on the top of the adjusting plate 10, a skipping needle 2 being provided on one side of the rotating seat 4, the skipping needle 2 passing through the interior of the limiting groove 13, a cylinder 5 passing through the top of one side of the frame 1, multiple sets of cylinder 5, skipping needle 2, tension spring 3, rotating seat 4 and adjusting seat 9 being provided, a metal plate 6 being provided on the top of one side of the inside of the frame 1, a thread break contact being provided on the top of the rotating seat 4, a tension spring 3 being hung on the bottom of one side of the rotating seat 4, an adjusting seat 9 being provided on one side of the bottom of the inside of the frame 1, and a thread feeder 1 being provided on one side of the bottom of the frame 1. 1. A lead coil 12 is provided on one side of the skip needle 2, and the tension spring 3 is attached to the top of the adjusting seat 9. When the device is in its original state, the cylinder 5 presses against the tail of the rotating seat 4, so that the skip needle 2 is in a horizontal state. After the yarn passes through the lead coil 12, the cylinder 5 retracts. At this time, the rotating seat 4 rotates counterclockwise under the action of the tension spring 3, causing the skip needle 2 to jump up. The skip needle 2 jumps to a certain height under the action of the tension spring 3 and the tension of the yarn. Then, the cylinder 5 pushes the rotating seat 4 back to its original position. In this way, the skip needle 2 can perform the reciprocating motion of jumping up and falling back, so that the yarn is in an alternating state of being taut and relaxed. When the yarn is broken, the tension of the yarn disappears, and the tension of the tension spring 3 pulls the rotating seat 4 to rotate counterclockwise, so that the skip needle 2 jumps up to the limit position. At this time, the broken wire contact point at the top of the rotating seat 4 contacts the metal piece 6, forming an electrical circuit, and the alarm works and sounds an alarm.

[0024] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, a fixing frame 14 is provided on the outer side of the limiting groove 13 on one side of the adjusting plate 10. The fixing frames 14 are arranged at equal intervals on one side of the adjusting plate 10. The bottom of the two ends of the fixing frame 14 is rotatably connected to the bottom. The two ends of the top of the inner side of the fixing frame 14 are rotatably connected to the side stabilizing shaft 18. The side stabilizing shaft 18 is symmetrically arranged at the top of the inner side of the fixing frame 14. The side stabilizing shaft 18 is perpendicular to the bottom stabilizing shaft 16. When the jumper needle 2 is driven to reciprocate and moves in the limiting groove 13, the bottom stabilizing shaft 16 and the side stabilizing shaft 18 rotate in opposite directions to avoid dry friction between the jumper needle 2 and the inner side wall of the limiting groove 13, which would cause wear to the jumper needle 2. The side stabilizing shaft 18 is provided with a first rubber sleeve 15, and the bottom stabilizing shaft 16 is provided with a second rubber sleeve 17. The first rubber sleeve 15 and the second rubber sleeve 17 protect the contact surface, further preventing the bottom stabilizing shaft 16 and the side stabilizing shaft 18 from causing wear to the jumper needle 2.

[0025] When the jumper needle 2 reciprocates and resets under the action of the tension spring 3 and the cylinder 5 and moves within the limiting groove 13, the bottom stabilizing shaft 16, which is rotatably connected between the two sides inside the fixed frame 14, and the side stabilizing shaft 18, which is rotatably connected to both ends of the inner top, rotate in both directions. This prevents the jumper needle 2 from generating dry friction with the inner wall of the limiting groove 13 on the adjusting plate 10, which would cause wear on the jumper needle 2 and reduce its service life. In addition, the first rubber sleeve 15 and the second rubber sleeve 17, which are provided on the outside of the bottom stabilizing shaft 16 and the side stabilizing shaft 18, isolate and protect the contact surface.

[0026] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, a limiting component is provided on the outside of the main shaft 8 at both ends of the rotating seat 4. The limiting component includes a ring-shaped stabilizing seat 7. The stabilizing seat 7 is provided on the outside of the main shaft 8 at both ends of the rotating seat 4. The stabilizing seat 7 limits the rotating seat 4 to a fixed position outside the main shaft 8, so as to prevent the rotating seat 4 from axially moving outside the main shaft 8, which would cause the skipped needle 2 to swing back and forth, affecting the normal delivery of the yarn and causing the device to malfunction. The inside of the stabilizing seat 7 is provided with a groove 20. The groove 20 is embedded with a limiting ball 21. There are multiple sets of limiting balls 21 in the groove 20. When the rotating seat 4 rotates, the limiting balls 21 rotate with it and roll in the groove 20 to avoid friction between the side of the rotating seat 4 and the inside of the stabilizing seat 7. The outside of the limiting balls 21 is provided with a wear-resistant coating 19. The wear-resistant coating 19 is evenly distributed on the outside of the limiting balls 21. The wear-resistant coating 19 makes the outside of the limiting balls 21 more wear-resistant.

[0027] When the rotating seat 4 is rotated outside the main shaft 8 by the action of the cylinder 5 and the tension spring 3, the stabilizing seat 7, which is fixedly connected to the outside of the main shaft 8 and located at both ends of the rotating seat 4, limits the rotating seat 4 to a fixed position outside the main shaft 8, preventing the rotating seat 4 from moving axially outside the main shaft 8. The limiting ball 21 set in the groove 20 can roll in the groove 20 set inside the stabilizing seat 7 when the rotating seat 4 rotates, avoiding friction between the side of the rotating seat 4 and the inside of the stabilizing seat 7, which would prevent it from rotating normally or even jamming and affect the normal operation of the device.

[0028] Working principle: When using the jumper device, in its initial state, cylinder 5 presses against the tail of the rotating seat 4, keeping the jumper needle 2 horizontal. After the yarn passes through the lead loop 12, cylinder 5 retracts. At this time, the rotating seat 4 rotates counterclockwise under the action of tension spring 3, causing the jumper needle 2 to jump up. Under the tension of tension spring 3 and yarn tension, the jumper needle 2 jumps to a certain height, and then cylinder 5 pushes the rotating seat 4 back to its original position. At the same time, the stabilizing seat 7 limits and stabilizes the rotating seat 4 outside the main shaft 8, preventing the rotating seat 4 from moving axially outside the main shaft 8. Simultaneously, the limiting ball 21 rolls in the groove 20 to prevent friction between the side of the rotating seat 4 and the inside of the stabilizing seat 7, which could cause it to malfunction or even jam, affecting the normal operation of the device. This process repeats continuously. Needle 2 can perform a reciprocating motion of jumping up and falling back, keeping the yarn in an alternating state of tension and relaxation. When the skipped needle 2 jumps up and resets under the action of tension spring 3 and cylinder 5, it moves within the limiting groove 13. The bottom stabilizing shaft 16 and the side stabilizing shaft 18 rotate accordingly, thereby preventing the skipped needle 2 from dry friction with the inner wall of the limiting groove 13 set on the adjusting plate 10, which would cause wear on the skipped needle 2. The first rubber sleeve 15 and the second rubber sleeve 17 isolate and protect the contact surface. When the yarn is broken, the tension of the yarn disappears, and the tension of tension spring 3 pulls the rotating seat 4 to rotate counterclockwise, causing the skipped needle 2 to jump to the limit position. At this time, the broken contact point at the top of the rotating seat 4 contacts the metal piece 6, forming an electrical circuit, and the alarm works and sounds an alarm.

[0029] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
