Description

Technical Field

[0001] This utility model relates to the field of sock machine technology, specifically to a sewing toe transfer device for open-end sock machines. Background Technology

[0002] A sock knitting machine is a machine used to knit socks.

[0003] The latest sock knitting machines have a sewing mechanism that sews the toe of the sock directly after knitting, completing the sock's shape. However, a large number of open-end sock knitting machines are still available on the market. After knitting, the operator removes the sock from the machine and then sews the toe of the sock manually to complete the shape.

[0004] The inventors of this application have discovered that socks produced by existing open-end sock machines have low sewing efficiency and are not suitable for automated production. Utility Model Content

[0005] The purpose of this invention is to provide a sewing toe transfer device for an open-face sock machine to solve the problems mentioned in the background art.

[0006] This utility model provides a sewing toe transfer device for an open-face sock machine, comprising: a frame, a transfer flip plate, a hook needle, a presser needle, a hook needle drive mechanism, a presser needle drive mechanism, and a drive motor;

[0056] As described in the background section of this application, there are still a large number of open-end sock machines on the market. After the socks are knitted, the operator removes them from the open-end sock machine and then sews the toes together using a manual sewing machine to complete the sock shaping.

[0057] The inventors of this application have discovered that socks produced by existing open-end sock machines have low sewing efficiency and are not suitable for automated production.

Figure 14 This is a schematic diagram of the fourth usage state of the seam head transfer device in this embodiment of the present utility model.

[0060] like Figures 1 to 14 As shown, the sewing toe transfer device for an open-face sock machine in this embodiment includes: a frame 1, a transfer flipping plate 2, a hook needle 3, a presser needle 4, a hook needle drive mechanism 5, a presser needle drive mechanism 6, and a drive motor.

[0061] One side of the frame 1 is mounted on the support shaft 11. The frame 1 can rotate around the support shaft 11 and can move up and down along the support shaft 11.

[0062] The drive motor (not shown in the figure) is mounted on the frame 1. The transfer and flipping disk 2 is circular and rotatably mounted on the frame 1. The transfer and flipping disk 2 is connected to the drive motor through a transmission mechanism. The drive motor is used to drive the transfer and flipping disk 2 to rotate.

[0063] Multiple first receiving slots are evenly distributed on the circumferential sidewall of the transfer and reversing disk 2. These first receiving slots are arranged along the axial direction of the transfer and reversing disk 2. Each first receiving slot of the transfer and reversing disk 2 contains a hook 3 and a pressure needle 4, with the hook 3 and pressure needle 4 fitting snugly together. The number of hooks 3 and pressure needles 4 on the transfer and reversing disk 2 is less than the number of sock needles 820 in the sock machine; preferably, the number of hooks 3 and pressure needles 4 corresponds to the number of sock needles 820 in the sock machine. The hook 3 is rotatably disposed within the first receiving slot of the transfer and reversing disk 2, with one end of the hook 3 protruding from the first receiving slot. The pressure needle 4 is vertically movable within the first receiving slot of the transfer and reversing disk 2.

[0064] The hook drive mechanism 5 and the presser needle drive mechanism 6 are respectively mounted on the frame 1.

[0065] The hook drive mechanism 5 is used to push the hook 3, causing the hook 3 to rotate. When the hook 3 rotates, it hooks the sock 810 on the sock machine. The presser needle drive mechanism 6 is used to drive the presser needle 4 to move up and down. When the presser needle 4 moves downward, it fixes the sock on the hook 3, locking the sock 810 between the hook 3 and the presser needle 4. Thus, the sock is controlled by the hook 3 and the presser needle 4, thereby transferring the sock from the sock needle of the sock machine to the transfer turntable 2. When the presser needle 4 moves upward, it releases the sock, and then the hook 3 rotates in the opposite direction to release the hooked sock.

[0066] The transfer and flipping disk 2 includes: transfer disk 21 and flipping disk 22.

[0067] Both the transfer plate 21 and the flip plate 22 are semi-circular. The transfer plate 21 is fixedly mounted on the frame 1, and the flip plate 22 is rotatably mounted on the frame 1.

[0068] The transfer plate 21 is designed as a 180-degree sock machine cylinder 830 structure, with half the number of hooks 3 and presser needles 4 on it. The flip plate 22 is also designed as a 180-degree sock machine cylinder structure, with half the number of hooks 3 and presser needles 4 on it as well. The transfer plate 21 and the flip plate 22 are joined together to form a circular transfer flip plate 2. After the sock is transferred to the transfer flip plate 2, the flip plate 22 is rotated 180 degrees along the axis of rotation. Because the sock is firmly controlled by the hooks 3 and presser needles 4, when the flip plate 22 is rotated, the bottom half of the sock loop will move closer to the top half of the sock loop as the flip plate 22 rotates, until it reaches the 180-degree position, where the bottom half of the sock loop and the top half of the sock loop are in contact. Then the frame 1 drives the transfer flip plate 2 to rotate, moving the transfer flip plate 2 to the position of the sewing machine 840, so that the sock 810 can be sewn by the sewing machine 840.

[0069] As can be seen from the above, the toe-sewing transfer device for the open-face sock machine in this embodiment includes a frame, a transfer and reversing plate, a hook needle, a presser needle, a hook needle drive mechanism, a presser needle drive mechanism, and a drive motor. The drive motor and the transfer and reversing plate are mounted on the frame. The transfer and reversing plate is evenly distributed with multiple first receiving slots, each containing a hook needle and a presser needle. The hook needle drive mechanism and the presser needle drive mechanism are respectively mounted on the frame. The hook needle drive mechanism is used to rotate the hook needle, and the presser needle drive mechanism is used to move the presser needle up and down to fix the sock to the hook needle. The transfer and reversing plate includes a transfer plate and a reversing plate. After being rotated 180 degrees, the reversing plate overlaps directly below the transfer plate to allow the toe-sewing machine to sew the sock toe. In this embodiment, the seam transfer device for an open-face sock machine operates as follows: After the sock is knitted, the machine frame moves the transfer turntable to a position directly above the sock machine cylinder. Then, the hook drive mechanism pushes the hook to rotate, hooking the sock on the machine. The presser needle drive mechanism moves the presser needle downwards, and the presser needle and hook cooperate to control the sock, thereby transferring it onto the transfer turntable. The turntable then rotates 180 degrees along its axis of rotation. During this rotation, the bottom half of the sock's loop moves closer to the top half of the loop until they are in contact. The machine frame then moves the transfer turntable to the seam sewing machine, which sews the sock to the top, completing the sock forming process. This method allows for fast sock forming and is suitable for automated production.

[0070] Optional, such as Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 10As shown, the sewing toe transfer device for the open-end sock machine in this embodiment further includes: a wire ring 7.

[0071] Both the transfer plate 21 and the tilting plate 22 have a second receiving groove on their circumferential sidewalls, which are arranged along the circumferential direction. The wire ring 7 is semi-circular, and two wire rings 7 are respectively embedded in the second receiving grooves of the transfer plate 21 and the tilting plate 22.

[0072] The hook 3 has a first slot 31 at its middle position and an opening slot 32 at its bottom position. The hook 3 is placed in the first receiving slot of the transfer and flipping disc 2, and the wire ring 7 is embedded in the first slot 31 of the hook 3. The hook 3 can rotate around the wire ring 7. When the bottom end of the hook 3 rotates inward, the opening slot 32 of the hook 3 allows a sock to be inserted to hook onto the sock on the sock machine.

[0073] The presser needle 4 has a guide groove 41, which is vertically arranged. The presser needle 4 is positioned within the first receiving groove of the transfer flip plate 2, and the wire ring 7 is embedded in the guide groove 41 of the presser needle 4. The presser needle 4 can move up and down along the wire ring 7. When the presser needle 4 moves downward, it closes the opening groove 32 of the hook needle 3, thereby controlling the sock. When the presser needle 4 moves upward, the opening groove 32 of the hook needle 3 opens, and when the bottom end of the hook needle 3 rotates outward, the sock is released.

[0074] Furthermore, in this embodiment, the sewing head transfer device for the open-end sock machine has a locking protrusion 42 at the bottom of the pressure needle 4.

[0075] The bottom end of the hook 3 is provided with a locking groove 33, and the top end of the hook 3 is provided with an arc-shaped protrusion 34.

[0076] When the pressure needle 4 moves downward, the locking protrusion 42 of the pressure needle 4 is inserted into the locking groove 33 of the hook needle 3. The arc-shaped protrusion 34 of the hook needle 3 cooperates with the locking protrusion 42 of the pressure needle 4. The arc-shaped protrusion 34 locks the locking protrusion 42 of the pressure needle 4, preventing the pressure needle 4 from moving upward.

[0077] Optional, such as Figure 4 and Figure 8 As shown, the stitch transfer device for the open-end sock machine in this embodiment includes a hook drive mechanism 5 comprising a first cylinder 51 and a hook pusher block 52.

[0078] The first cylinder 51 is mounted on the frame 1, and the hook pusher block 52 is mounted on the first cylinder 51. The hook pusher block 52 is connected to the movable rod of the first cylinder 51.

[0079] There are two hook push blocks 52: an upper push block 521 and a lower push block 522. The upper push block 521 and the lower push block 522 are respectively mounted on the first cylinder 51 and connected to the movable rod of the first cylinder 51. They are located outside the hook 3 (transfer and flip plate) and are located below and below the wire ring 7, respectively.

[0080] The hook 3 is set in the first receiving groove of the transfer flip disk 2, and one end of the hook 3 protrudes from the side wall of the transfer flip disk 2. The movable rod of the first cylinder 51 drives the upper push block 521 and the lower push block 522 to extend and retract alternately. When the upper push block 521 and / or the lower push block 522 extend, they push the part of the hook 3 that protrudes from the transfer flip disk 2, so that the hook 3 rotates around the wire ring 7.

[0081] In this embodiment, the drive motor drives the transfer and flipping disk 2 to rotate. When the first cylinder 51 drives the lower push block 522 to extend (at this time, the upper push block retracts), the hooks 3 on the transfer and flipping disk 2 pass through the lower push block 522 in sequence. The lower push block 522 pushes the bottom end of the hooks 3, and the hooks 3 rotate around the wire ring 7, so that the bottom opening groove 32 of the hooks 3 moves closer to the sock until the sock on the sock machine is hooked. When the first cylinder 51 drives the upper push block 521 to extend (at this time, the lower push block retracts), the hooks 3 on the transfer and flipping disk 2 pass through the upper push block 521 in sequence. The upper push block 521 pushes the top end of the hooks 3, so that the hooks 3 rotate in the opposite direction around the wire ring 7, so that the bottom opening groove 32 of the hooks 3 moves outward, the hooks 3 reset, and the sock is released.

[0082] Furthermore, in this embodiment, the sewing toe transfer device for the open-end sock machine has the same structure for the upper push block 521 and the lower push block 522, both of which are right-angled L-shaped. Both the upper push block 521 and the lower push block 522 include a connecting rod 5201 and a push rod 5202.

[0083] The connecting rod 5201 is connected to the movable rod of the first cylinder 51. The side of the push rod 5202 includes an inclined section 52021 and a flat section 52022, which are connected to each other.

[0084] In this embodiment, when the hook pusher block 52 extends, the hook 3 abuts against the inclined section 52021 of the push rod 5202. The hook 3 slides along the inclined section 52021 to the flat section 52022 of the push rod 5202, thereby pushing the hook 3 and causing the hook 3 to rotate around the wire ring 7.

[0085] Furthermore, in this embodiment, the sewing head transfer device for the open sock machine has two first sliding grooves 511 in the first cylinder 51. The connecting rods 5201 of the upper push block 521 and the lower push block 522 are slidably disposed in the two first sliding grooves 511 of the first cylinder 51 and are connected to the movable rod of the first cylinder 51 through the connecting column 5203.

[0086] Optional, such as Figure 2 and Figure 9 As shown, the sewing head transfer device for the open-end sock machine in this embodiment includes a pressure needle drive mechanism 6 comprising a second cylinder 61 and a pressure needle pusher block 62.

[0087] The second cylinder 61 is mounted on the frame 1, and the pressure needle pusher 62 is mounted on the second cylinder 61 and connected to the movable rod of the second cylinder 61. The second cylinder 61 is used to drive the pressure needle pusher 62 to move up and down.

[0088] The top of the pressure needle 4 has a protrusion 401.

[0089] The pressure needle pusher 62 is provided with a limiting groove 621. The limiting groove 621 of the pressure needle pusher 62 is used for the protrusion 401 of the pressure needle 4 to be inserted, so that the pressure needle pusher 62 drives the pressure needle 4 to move up and down when it moves up and down.

[0090] In this embodiment, the drive motor drives the transfer and flipping disk to rotate, causing the protruding parts of the presser needles to pass sequentially through the limiting grooves of the presser needle pusher block. After the second cylinder drives the presser needle pusher block to rise and fall, when the presser needles on the transfer and flipping disk pass through the limiting grooves of the presser needle pusher block, the presser needle pusher block drives the presser needles to rise and fall sequentially. When the presser needles descend, they press the sock against the hook needle; when the presser needles rise, they release the sock needles that are pressing against the hook needle.

[0091] Furthermore, in this embodiment, the sewing toe transfer device for the open-end sock machine, the needle drive mechanism 6, also includes a slider 63.

[0092] The side wall of the second cylinder 61 is provided with a second sliding groove 611. The slider 63 is slidably disposed in the second sliding groove 611 of the second cylinder 61 and connected to the movable rod of the second cylinder 61. The pressure needle push block 62 is disposed on the slider 63 and moves up and down together with the slider 63.

[0093] Furthermore, in this embodiment, the sewing toe transfer device for the open-end sock machine has a limiting groove 621 of the pressure needle push block 62 in the shape of an arc-shaped trumpet.

[0094] The large end of the limiting groove 621 is located on both sides of the pressure needle push block 62. The limiting groove 621 forms a large opening on the end face of the pressure needle push block 62. The small end of the limiting groove 621 is located in the middle of the pressure needle push block 62.

[0095] In this embodiment, after the second cylinder drives the pressure needle pusher block to move up and down, the pressure needles on the transfer flip plate sequentially enter the limiting groove from the end face opening of the pressure needle pusher block and slide along the arc-shaped limiting groove, thereby driving the pressure needles to move up and down.

[0096] The sewing toe transfer device for open-face sock machines of this utility model operates as follows:

[0097] After the socks 810 are knitted on the sock knitting machine, the frame 1 drives the transfer turntable 2 to rotate, moving the transfer turntable, which is equipped with the same number of hooks and presser needles as the sock needles, to directly above the sock knitting machine cylinder 830 and concentric with it. Then, all the sock needles 820 on the sock knitting machine, carrying the socks 810, are raised to a certain height, so that each hook 3 is inserted between two adjacent sock needles 820, resulting in... Figure 11 The state shown.

[0098] When the hook 3 and the sock needle 820 reach a suitable height difference, the first cylinder drives the push block to extend. The push block pushes the bottom end of the hook to rotate towards the center, that is, the opening groove of the hook moves closer to the seam loop of the sock until it completely hooks the sock. After the hook has completely hooked the sock, the second cylinder drives the pressure needle push block to move downward. The pressure needle push block drives the pressure needle 4 to move downward to seal the opening groove of the hook, so that the sock 810 is controlled by each hook 3 and pressure needle 4. The sock machine cylinder and the transfer and reversing plate rotate synchronously. The sock loop is detached from the sock needle by the uncoiling knife and the pressure needle knife and transferred to the transfer and reversing plate, realizing the transfer of the sock from the sock machine cylinder to the transfer and reversing plate, resulting in... Figure 12 The state shown.

[0099] Then, the rotating disc 22 rotates 180 degrees along the axis of rotation. Because the crochet hook 3 and presser needle 4 firmly hold the sock in place, as the rotating disc 22 rotates, the bottom half of the sock's loops move closer to the top half of the loops, until they reach the 180-degree position, where the bottom half of the sock's loops and the top half of the loops are perfectly aligned, resulting in... Figure 13 The state shown.

[0100] Then, the frame drives the transfer turntable to rotate, moving the transfer turntable containing the socks to the sewing machine 840, resulting in... Figure 14 The state shown.

[0101] Finally, the sewing machine 840 moves forward to the intersection of the upper and lower hooks, and the instep loop and the sole loop are woven together by the sewing needle to complete the sewing of the sock.
