Description

Technical Field

[0001] The invention relates to the technical field of sock production equipment, and in particular to a clamping claw assembly and a sock turning device for turning socks. Background Art

[0002] Sock turning is to turn the outside and inside of the socks over and off, turn the outside of the socks to the inside, and turn the inside to the outside, so as to further process the socks. The sock turning tube is an auxiliary equipment used in sock production, which is mainly used to remove the socks from the sock knitting machine and turn them inside out. The sock turning tube includes a sleeve, and the working principle is: the socks are inserted from one end of the sleeve, and the sleeve is fixed on the workbench through an axial seat and can move axially freely. The first cylinder pushes the push sleeve upward to open the socks outside the sleeve; the fan generates suction to suck the socks into the sleeve. After the shearing is completed, the third cylinder returns to its position and the shearing device returns to its position at the same time, and the first cylinder and the second cylinder cooperate to suck the socks out of the sleeve and complete the turning. After the sock turning operation is completed, each component is reset and waits for the next sock operation.

[0003] The clamp on the sock turning tube (sleeve) is an important component on sock turning machines and other equipment. The clamp can clamp the sleeve and can move relative to the sleeve along its axial direction, playing the role of sock positioning, auxiliary turning, and stable support. When the socks are conveyed to the sock turning tube, the clamp will first position the socks. Through driving methods such as mechanical transmission devices or pneumatic devices, the clamp will approach the socks and gradually clamp the socks on the sock turning tube. As the sock turning tube rotates or moves, the clamp will maintain the clamping force on the socks, so that the socks can smoothly turn over following the movement of the sock turning tube. The presence of the clamp can prevent the socks from slipping or deforming during the turning process, ensuring the quality and efficiency of sock turning.

[0031] Combine the following Figure 1-Figure 5 The technical solution provided by the present invention is described in more detail.

[0032] Embodiment 1:

[0033] The present invention provides a clamping claw assembly for turning socks, comprising a mounting seat 1, a claw portion 3, a driving mechanism and a shifting block 4, wherein: the mounting seat 1 is sleeved outside the sleeve 10, the claw portion 3 is rotatably connected to the mounting seat 1 through a shaft body 33, the number of the claw portions 3 is at least three, and all the claw portions 3 are arranged at intervals around the axis of the sleeve 10; the claw portion 3 comprises a clamping end 32 and a prying end 31, the shaft body 33 is located between the clamping end 32 and the prying end 31, and the three form a lever structure; the driving mechanism can push the corresponding prying end 31 to move, so that the clamping end 32 rotates toward the axis direction of the mounting seat 1 with the shaft body 33 as the axis, so that all the clamping ends 32 cooperate to clamp and fix the sleeve 10; and when the driving mechanism removes the thrust, the claw portion 3 can rotate and reset.

[0034] The shaft body 33 is located between the clamping end 32 and the prying end 31 , and the three are an integrally formed lever structure, which has rapid linkage, timely response and stable structure.

[0035] In the clamping claw assembly for turning socks of the present embodiment, all the claws 3 are arranged at intervals around the axis of the sleeve 10, which can clamp the sleeve 10 or move the socks more stably, and the shaft 33, the clamping end 32 and the prying end 31 of the claw 3 form a lever structure, and the driving mechanism can push the corresponding prying end 31 to move, so that the clamping end 32 rotates toward the axis direction of the mounting seat 1 with the shaft 33 as the axis center, and all the clamping ends 32 cooperate to clamp and fix the sleeve 10, and the claw 3 can be rotated to reset. The structure of the clamping claw assembly is more stable, which is convenient for moving or clamping socks, easy to use, and improves the working efficiency of turning socks.

[0036] As an optional embodiment, the mounting seat 1 and the sleeve 10 are coaxially arranged, and the claws 3 are evenly spaced around the axis of the mounting seat 1. When there are three claws 3, the three claws 3 are respectively located at three equally divided points of the circumference of the mounting seat 1.

[0037] In this embodiment, the three claws 3 cooperate with the sleeve 10 to provide a more stable force, and the central angle between two adjacent claws 3 and the center of the mounting seat 1 is 120°.

[0038] As an alternative embodiment, see Figure 2 and Figure 3 As shown, a limiting groove 101 is provided on the outer wall of the mounting seat 1 of this embodiment, and the limiting groove 101 passes through the upper and lower sides of the mounting seat 1. The shaft 33 is rotatably connected to the opposite sides of the limiting groove 101, and the claw portion 3 is rotatably arranged in the limiting groove 101.

[0039] The limiting groove 101 can limit the rotation of the claw 3 in the vertical direction, prevent the claw 3 from shifting left and right, and ensure the stability of the structure.

[0040] As an alternative embodiment, see Figure 2 and Figure 3 As shown, the clamping end 32 and the prying end 31 are an integrally formed bent rod or bent plate structure, and the clamping end 32 has an arc-shaped clamping surface 321 for matching with the outer wall of the sleeve 10 .

[0041] The arc-shaped clamping surface 321 can fit closely with the outer wall of the sleeve 10, improve the clamping force of the claw 3 on the sleeve 10, and enable the sleeve 10 and the claw 3 to move axially synchronously or asynchronously. Of course, the sleeve 10 and the claw 3 can move relative to each other along their axial directions, which can be achieved through the structure of the motor and the screw nut pair. As an existing mature technology, it will not be described in detail here.

[0042] As an alternative embodiment, see Figure 2 and Figure 3 As shown, the prying end 31 and the clamping end 32 are located on opposite sides of the mounting base 1 , and the driving mechanism and the prying end 31 are located on the same side of the mounting base 1 .

[0043] When the driving mechanism pushes the prying end 31 , the claw portion 3 rotates around the shaft 33 , and the prying end 31 moves in a direction away from the axis of the mounting seat 1 . At the same time, the clamping end 32 moves in a direction close to the axis of the mounting seat 1 , thereby cooperating with the other clamping ends 32 to clamp the sleeve 10 .

[0044] As an alternative embodiment, see Figure 1 As shown, each clamping jaw assembly is in transmission connection with the corresponding driving mechanism. The driving mechanism of this embodiment includes a driving device and a shifting block 4, wherein: a mounting block 6 is fixed on the mounting seat 1, and the shifting block 4 is rotatably connected to the mounting block 6 through a pin shaft 43, and the shifting block 4 includes a driving portion 42 and a shifting portion 41, wherein the driving portion 42 is used to contact the driving device, and the prying end 31 is located on the rotation path of the shifting portion 41, and the driving device can push the driving portion 42 to rotate with the pin shaft 43 as the axis, so that the shifting portion 41 pushes the prying end 31 to move. The driving device includes a driving push rod 5, and the driving push rod 5 is telescopically arranged, and the driving portion 42 is located on the moving path of the driving push rod 5.

[0045] The driving push rod 5 can be an electric push rod or a pneumatic push rod. The driving push rod 5 in this embodiment is a pneumatic push rod, and the air source enters the pneumatic push rod from the air inlet head 7.

[0046] For details, see Figure 1 As shown, when the driving push rod 5 is extended, it can push the driving part 42 of the shift block 4, so that the entire shift block 4 rotates with the pin shaft 43 as the axis, and the shifting part 41 of the shift block 4 rotates, and the shifting part 41 pushes the prying end 31 of the claw part 3, combined with Figure 2 and Figure 3 As shown, the claw portion 3 rotates around the shaft body 33 , and the clamping end 32 clamps the sleeve 10 .

[0047] As an alternative embodiment, see Figure 1 As shown, a limit adjustment member 8 is fixed on the outer ring of the mounting seat 1 , and the limit adjustment member 8 is used to abut against the shifting portion 41 , thereby limiting the rotation angle of the shifting block 4 .

[0048] The limit adjustment member 8 can limit the rotation angle of the rotating block of the toggle portion 41, thereby limiting the rotation angle of the claw portion 3. The limit adjustment member 8 can adjust its own length, such as by adjusting in the form of screws, bolts, etc.

[0049] As an alternative embodiment, see Figure 1 As shown, the clamping jaw assembly also includes a reset spring 2, one end of the reset spring 2 is fixedly connected to the inner ring of the mounting seat 1, and the other end of the reset spring 2 is fixedly connected to the prying end 31 for driving the prying end 31 to reset.

[0050] When the driving push rod 5 retracts, the driving push rod 5 no longer pushes the shifting block 4. The claw portion 3 is reset under the deformation restoring force of the reset spring 2. Figure 2 As shown, the return spring 2 pulls the prying end 31 of the claw 3, and the clamping end 32 opens.

[0051] See also Figure 1-Figure 3 As shown, the working process of the clamping claw assembly for turning over socks in this embodiment is as follows:

[0052] See also Figure 2 As shown, when the clamping jaw assembly is in the initial position, the clamping end 32 of the claw portion 3 is open, see Figure 1 and Figure 3 As shown, the driving push rod 5 extends out to push the shift block 4 to rotate around the pin shaft 43. Specifically, the shifting portion 41 of the shifting block 4 pushes the prying end 31 of the claw portion 3, as shown in FIG. Figure 3 As shown, the claw 3 rotates in the limit groove 101 with the shaft 33 as the axis, and the clamping end 32 moves toward the axis direction of the mounting seat 1 to clamp the sleeve 10. When the driving push rod 5 retracts, the shift block 4 loses its driving force, and the return spring 2 pulls the prying end 31 of the claw 3 to move toward the axis direction of the mounting seat 1, and the clamping end 32 of the claw 3 opens and returns to its original position.

[0053] Example 2

[0054] See also Figure 4 and Figure 5 As shown, this embodiment provides a sock turning device, including a sleeve 10 and the above-mentioned clamping claw assembly for turning socks.

[0055] See also Figure 1 As shown, the mounting base 1 is connected to the support arm 9, and the sleeve 10 is movably arranged on the machine base 11.

[0056] The sleeve 10 and the claw portion 3 can respectively move relative to each other along their axial directions. Specifically, this can be achieved through the structure of a motor and a lead screw nut pair. As this is an existing mature technology, it will not be elaborated here.

[0057] Among them, the sock turning operation is consistent with the method in the prior art. The sock turning tube includes a sleeve, and the working principle is: the sock is inserted from one end of the sleeve, the sleeve is fixed on the workbench through a bearing seat, and can rotate freely, the first cylinder pushes the push sleeve to move upward, so that the sock is opened in the sleeve; the fan generates suction to suck the sock into the sleeve. After the shearing is completed (depending on whether the socks need to be sheared), the third cylinder returns to its position and the shearing device returns to its position at the same time, and the first cylinder and the second cylinder cooperate to move the sock out of the sleeve and complete the turning. After completing the sock turning operation, each component is reset and waits for the next sock operation.

[0058] The clamping claw assembly on the sock turning tube (sleeve) can clamp the sleeve and can move relative to the sleeve along its axial direction, thereby playing the role of sock positioning, auxiliary turning, and stable support. When the socks are conveyed to the sock turning tube, the clamping claw assembly will first position the socks. Through driving methods such as mechanical transmission devices or pneumatic devices, the clamping claw assembly will approach the socks and gradually clamp the socks on the sock turning tube. As the sock turning tube rotates or moves, the clamping claw assembly will maintain the clamping force on the socks, so that the socks can smoothly follow the movement of the sock turning tube to turn over. The presence of the clamping claw assembly can prevent the socks from slipping or deforming during the turning process, thereby ensuring the quality and efficiency of the sock turning.

[0059] The sock turning device of this embodiment has a clamping claw assembly, and the structure of the clamping claw assembly is more stable, which is convenient for moving or clamping socks, easy to use, and improves the working efficiency of sock turning.
