Description

Technical Field

[0001] The invention relates to the field of textile equipment, and in particular to a pushing device for a sock machine and the sock machine. Background Art

[0002] With the development of textile machinery, fully automatic integrated sock machines have gradually occupied a dominant position in the sock machine market. The sock machine includes a sock knitting grabbing device and a sewing head device. After the socks are knitted on one side of the sock knitting device, the picking device transfers the knitted socks with both ends open to the sewing head device, and the sewing head device completes the flipping and stitching. However, when the sewing head device is flipped and stitched, the lower part of the socks needs to be stored in the lower sock tube first, especially for long socks. For example, the patent with publication number CN208201288U in the prior art moves the sock tube in an inclined direction to store the lower end of the long sock into the sock tube, so as to perform subsequent flipping and stitching operations. However, in the process of storing the end of the long socks, the socks may be too long and the socks are relatively soft, resulting in the end of the socks being piled up or congested in the sock tube after being stored in the sock tube, which affects the subsequent flipping and sewing operations. Summary of the invention

[0003] In view of this, the present invention aims to provide a pushing device for a sock machine and a sock machine, so as to solve the problem in the prior art that the inside of the sock tube is uneven when the stockings are sucked into the sock tube, thus affecting the subsequent operation of the sock machine.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] A pushing device for a sock machine comprises a driving assembly and a pushing assembly, wherein one end of the pushing assembly is connected to the driving assembly, and the driving assembly drives the pushing assembly to retract and rotate. The driving assembly comprises a vertical driving part and a rotating driving part, one end of the pushing assembly is coaxially connected to the vertical driving part, and one end of the pushing assembly is telescopically installed inside the vertical driving part, and the pushing assembly is driven by the vertical driving part to rise and open or descend and retract, and the rotating driving part is connected to one end of the pushing assembly close to the vertical driving part, and the pushing assembly is driven by the rotating driving part to rotate.

[0006] Furthermore, the pushing assembly includes a telescopic rod, a connecting rod and a pushing rod, the telescopic rod is connected to the vertical driving part and the rotating driving part, the top end of the telescopic rod is connected to the connecting rod, the other end of the connecting rod is connected to the pushing rod, and the pushing rod extends downward.

[0007] Furthermore, the pushing rod is arranged in parallel with the telescopic rod, and the connecting rod is perpendicular to the telescopic rod and the pushing rod.

[0008] Furthermore, the vertical driving unit includes a first driving element, the interior of the first driving element is configured as a hollow structure, the telescopic rod is connected to the first driving element, and the telescopic rod is coaxially arranged with the first driving element, and the telescopic rod can move telescopically within the first driving element.

[0009] Furthermore, the rotary drive unit includes a second drive element, a first drive disk and a second drive disk, the first drive disk and the second drive disk are both arranged on the upper part of the second drive element, the first drive disk and the second drive disk are connected by belts, and the telescopic rod of the pushing assembly is connected to the second drive disk.

[0010] Furthermore, the second driving disk is coaxially arranged with the vertical driving part.

[0011] Furthermore, the rotary drive unit also includes a rotary base, which is arranged on the upper part of the second drive element and the lower part of the first drive disk and the second drive disk, and is used to support and fix the first drive disk and the second drive disk.

[0012] Furthermore, a concave cavity is provided on the rotating base, and the first driving disk and the second driving disk are both located in the concave cavity.

[0013] Compared with the prior art, the pushing device for a sock machine described in the present invention has the following advantages:

[0014] By adding a pushing device to the sock machine, the socks on the sock machine's sewing head device can be more stably sucked into the sock tube. When the pushing device is not needed, the vertical driving unit drives the pushing assembly to be in a retracted state, and the rotary driving unit controls the pushing assembly to be in an initial state, which is that the pushing assembly is away from the sock tube of the sock machine's sewing head device; when the pushing device is needed, the vertical driving unit drives the pushing assembly to rise and open, and the rotary driving unit drives the pushing assembly to rotate above the sock tube, and then the vertical driving unit drives the pushing assembly to move downward until the pushing assembly at least partially extends into the sock tube, so as to achieve stable suction and sorting of the sock tube. After the pushing operation is completed on the socks, the vertical driving unit drives the pushing assembly to rise again until the end of the pushing assembly is separated from the sock tube, and the rotary driving unit drives the pushing assembly to rotate and recover to be away from the sock tube, and finally the vertical driving unit drives the pushing assembly to retract downward to the initial state again, so as to avoid interference with the movement of other parts, thereby avoiding affecting subsequent operations. In addition, the present application sets the rotary driving unit and the vertical driving unit together to save space.

[0015] The present invention also provides a sock machine, comprising the above-mentioned pushing device for the sock machine.

When the pushing device is not needed, the vertical driving unit 11 drives the pushing assembly to be in a retracted state, and the rotary driving unit 12 controls the pushing assembly 2 to be in an initial state, which is the pushing assembly away from the sock tube 102 of the sock machine sewing device; when the pushing device is needed, the vertical driving unit 11 drives the pushing assembly to rise and open, and the rotary driving unit 12 drives the pushing assembly to rotate to the top of the sock tube, and then the vertical driving unit 11 drives the pushing assembly to move downward until the pushing assembly at least partially extends into the sock tube to achieve stable suction and sorting of the sock tube. After the pushing operation is completed on the socks, the vertical driving unit 11 drives the pushing assembly to rise again until the end of the pushing assembly is separated from the sock tube, and the rotary driving unit 12 drives the pushing assembly to rotate and return to the sock tube. Finally, the vertical driving unit 11 drives the pushing assembly to shrink downward to the initial state again to avoid interference with the movement of other parts, thereby avoiding affecting subsequent operations. In addition, the solution of the present application sets the rotary driving unit and the vertical driving unit together to save space.

[0029] The pushing assembly 2 includes a telescopic rod 21, a connecting rod 22 and a pushing rod 23, wherein the telescopic rod 21 is connected to the vertical driving part 11 and the rotating driving part 12, the top end of the telescopic rod 21 is connected to the connecting rod 22, the other end of the connecting rod 22 is connected to the pushing rod 23, and the pushing rod 23 extends downward. The telescopic rod 21 drives the connecting rod 22 and the pushing rod 23 to rise and fall and rotate. Furthermore, the pushing rod 23 is arranged in parallel with the telescopic rod 21, and the connecting rod 22 is perpendicular to the telescopic rod 21 and the pushing rod 23, thereby ensuring the accuracy of the up and down movement and rotation of the pushing rod.

[0030] Furthermore, the vertical driving unit 11 includes a housing and a first driving element 110. The first driving element 110 is provided with a hollow structure inside. The telescopic rod 21 is connected to the first driving element 110, and the telescopic rod 21 is provided coaxially with the first driving element 110.

[0031] In this embodiment, the rotation drive unit 12 includes a second drive element 120, a first drive disk 121, and a second drive disk 122, wherein the first drive disk 121 and the second drive disk 122 are both arranged on the upper part of the second drive element 120, the first drive disk 121 and the second drive disk 122 are connected by a belt, the telescopic rod 21 is connected to the second drive disk 122, the first drive disk 121 is driven to rotate by the second drive element 120, the first drive disk 121 drives the second drive disk 122 to rotate by the belt, and then the telescopic rod 21 is driven to rotate by the second drive disk 122. Preferably, the second drive element 120 described in this embodiment can be set as a motor, and the motor shaft is connected to the first drive disk 121.

[0032] Furthermore, the second driving disk 122 of the rotary driving unit 12 is coaxially arranged with the telescopic rod 21 and the vertical driving unit 11, so as to accurately drive the telescopic rod to rotate.

[0033] Furthermore, the rotary drive unit 12 further includes a rotary base 123, which is arranged on the upper part of the second drive element 120 and the lower part of the first drive disk 121 and the second drive disk 122, and the rotary base 123 is used to support and fix the first drive disk 121 and the second drive disk 122. A concave cavity is arranged on the rotary base 123, and the first drive disk 121 and the second drive disk 122 are both located in the concave cavity, so that the upper surface of the first drive disk 121 and the second drive disk 122 is basically flush with the upper surface of the rotary base 123, so that the upper surface of the pushing assembly 2 is basically flat when it is in the initial state, preventing the accumulation of textile fiber scraps or fabric waste on the surface of the pushing assembly, thereby ensuring the working stability of the pushing device.

[0034] As part of an embodiment of the present invention, the pushing rod 23 is configured as a detachable structure, and the length of the pushing rod 23 can be replaced according to the length of the socks, thereby achieving the pushing and sorting of socks of different lengths, so that stockings of different lengths can be stably sucked into the sock tube, and the applicability is strong.

[0035] Furthermore, the pushing rod 23 can be set to a structure that is thick at the top and thin at the bottom, or thin at the top and thick at the bottom, or uniform at the top and bottom, and the outer diameter of the pushing rod 23 is smaller than the inner diameter of the sock tube, so that the pushing rod can smoothly move up and down in the sock tube.

At least part of the connector 3 is located below the lower cover 103.

[0038] Specifically, the connecting member 3 includes a first connecting part 31, a second connecting part 32 and a third connecting part 33, the top of the first connecting part 31 is connected to the second connecting part 32, the end of the second connecting part 32 away from the first connecting part 31 is connected to the third connecting part 33, and the third connecting part 33 extends upward, wherein the first connecting part 31 is connected to the lower component 101, and the third connecting part 33 is connected to the pushing device, thereby fixing the pushing device on the seam head device 100.

[0039] Furthermore, the first connection part 31, the second connection part 32 and the third connection part 33 form a Z-shaped structure, the first connection part 31 and the second connection part 32 are both located at the lower part of the lower top cover 103, and the third connection part 33 is located at the side of the lower top cover 103, thereby making the upper surface of the pushing device flush with or slightly higher than the lower top cover 103 when it is in the initial state, reducing the up and down movement path of the pushing component, thereby shortening the pushing time.

[0040] As part of the embodiment of the present invention, in order to fully illustrate the working process of the pushing device, the working process of each component in each state is described as follows:

[0041] In the initial storage state, if Figure 6 As shown, the pushing assembly 2 is away from the sock tube 102, and the telescopic rod 21 of the pushing assembly 2 is in a retracted state;

[0042] When the socks in the sock tube 102 need to be arranged and pushed, the vertical driving unit 11 controls the telescopic rod 21 of the pushing assembly 2 to move upward, thereby driving the connecting rod 22 and the pushing rod 23 to move upward until the pushing assembly is in the initial lifting state;

[0043] Then the rotary drive unit 12 drives the telescopic rod 21 of the pushing assembly to rotate, thereby driving the connecting rod 22 and the pushing rod 23 to rotate until the pushing rod 23 is located directly above the sock tube 102, forming a rotating lifting state;

[0044] The vertical driving part 11 controls the telescopic rod 21 of the pushing assembly 2 to move downward, thereby driving the connecting rod 22 and the pushing rod 23 to move downward until the pushing rod 23 extends into the inside of the sock tube 102, forming a pushing state, and performing a pushing and sorting operation on the socks.

[0045] After the pushing and pressing is completed, the vertical driving part 11 controls the telescopic rod 21 of the pushing assembly 2 to move upward, thereby driving the connecting rod 22 and the pushing rod 23 to move upward until the pushing assembly is in a rotating lifting state;

[0046] The rotation driving part 12 drives the telescopic rod 21 of the pushing assembly to rotate, thereby driving the connecting rod 22 and the pushing rod 23 to rotate until the pushing rod 23 is away from the sock tube 102, forming an initial lifting state;

[0047] The vertical driving part 11 controls the telescopic rod 21 of the pushing assembly 2 to move downward, thereby driving the connecting rod 22 and the pushing rod 23 to move downward until the telescopic rod 21 is stored inside the vertical driving part 11, forming a retracted state. The entire cyclic operation of the complete pushing device, one cycle is: retracted state → initial lifting state → rotation lifting state → pushing state → rotation lifting state → initial lifting state → retracted state, and then the next cycle starts from the retracted state.

[0048] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
