Description

Technical Field

[0001] This utility model relates to the field of sock machine equipment technology, and more specifically, to a height adjustment device for a cap and a sock machine. Background Technology

[0002] Whether for warmth, fashion, or foot protection, socks are indispensable. Sock knitting machines, the machines that produce socks, are becoming increasingly common. However, in the sock knitting process, the cap is a crucial component for closing the toe box, and the precision of its connection to the cylinder directly affects the sock yield. In existing technology, the cap is typically fixed directly above the cylinder, and its parallelism depends on machining and assembly precision. However, errors in parallelism during processing and assembly can occur. For example, the mounting surface of the cap and the top plane of the cylinder may have micron-level dimensional and positional tolerances (such as flatness and perpendicularity errors). These, combined with assembly gaps, can easily lead to the cap and cylinder working surface not being parallel, causing uneven pressure on the fabric and thus increasing the product defect rate.

[0003] Prior art, disclosed in CN 220550304U, is a cap cover assembly, including a cap cover, a main shuttle assembly, an auxiliary shuttle assembly, a sliding door assembly, and an upper steel ring assembly. The main shuttle assembly, auxiliary shuttle assembly, sliding door assembly, and upper steel ring assembly are all mounted on the cap cover, with the upper steel ring assembly located inside the cap cover. The upper steel ring assembly is connected to both the main shuttle assembly and the sliding door assembly. The main shuttle assembly includes a main shuttle body, which has nine or ten shuttles, used to grade and improve the thread cutting rate of the sock machine. However, in existing cap covers, any error in parallelism during processing and assembly can easily lead to an increase in product defect rates. Utility Model Content

[0004] In view of this, the present invention aims to provide a height adjustment device for a hat cap and a sock machine. This addresses the problem in the prior art where errors in the parallelism of the hat cap during processing and assembly easily lead to an increased product defect rate.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A hat cover height adjustment device is characterized in that it includes an upper column, a lower column, and a fixing component. The upper column is connected to the hat cover and is located above the lower column. The fixing component is disposed on the upper column and the lower column. The upper end of the lower column is provided with a second inclined surface. The upper column moves a certain displacement along the second inclined surface and is then fixed by the fixing component to realize the height adjustment of the hat cover.

[0007] This design allows for convenient adjustment of the cap height by moving the upper column a certain distance along the second inclined plane at the upper end of the lower column and fixing it with a fixing component. This meets the diverse height requirements of different usage scenarios or users. Furthermore, it effectively solves the problem of parallelism errors in the processing and assembly of caps in existing technologies. Because this adjustment device allows the upper column to move relative to the lower column, even if there is a certain parallelism deviation in the initial processing and assembly, the cap can be adjusted to a suitable state, reducing product defects caused by parallelism errors, thereby lowering the product defect rate and improving product quality and production efficiency. The entire device consists only of the upper column, lower column, and fixing component, with a relatively simple structure that facilitates manufacturing, installation, and use, reducing production costs and operational complexity.

[0008] Furthermore, the fixing component includes a support part and a tightening part. The support part is connected to the tightening part. The support part limits and supports the upper column, and the tightening part fixes the upper column.

[0009] This feature improves the stability of the entire height adjustment device while allowing for fine-tuning of the hat cover's parallelism, thereby increasing the product's pass rate.

[0010] Furthermore, two support parts and two tightening parts are provided, and the two support parts and two tightening parts are connected alternately.

[0011] Furthermore, the support portion includes a first support plate, one end of which is movably connected to the upper column, and the other end of which is fixedly connected to the lower column.

[0012] Furthermore, the first support plate is provided with at least a first through hole, a second through hole, a first fastener, and a second fastener. The first through hole is an inclined track hole, and the inclination of the first through hole is consistent with the inclination of the second inclined surface. The first fastener is inserted into the first through hole and connected to the upper end post, and the second fastener is inserted into the second through hole and connected to the lower end post.

[0013] This design enables precise height adjustment of the hat flap, ensures the stability and parallelism of the hat flap height, and features a simple structure with low operating costs.

[0014] Furthermore, the tightening part includes a second support plate, which is fixedly connected to the first support plate and movably connected to the upper end column.

[0015] Furthermore, the second support plate is provided with a fourth through hole and a fourth fastener, the fourth fastener being inserted into the fourth through hole and contacting the upper end post.

[0016] Furthermore, a fifth hole is provided on the second support plate, which is connected to the fourth through hole. After the sixth fastener is inserted into the fifth hole, the sixth fastener tightens the fourth fastener.

[0017] This setting can improve the stability of the upper column fixing, thereby improving the parallelism after the height of the cap is adjusted.

[0018] Furthermore, the fourth fastener is a screw, and the sixth fastener is a set screw.

[0019] A sock-making machine includes the height adjustment device described above.

[0020] Compared with existing technologies, the hat cover height adjustment device and sock machine described in this utility model have the following advantages:

[0021] 1) This utility model allows for convenient adjustment of the hat cap height by moving the upper column a certain distance along the second inclined surface at the upper end of the lower column and fixing it with a fixing component. This meets the diverse needs of different usage scenarios or users for hat cap height. Moreover, it effectively solves the problem of parallelism error in the processing and assembly of hat caps in the prior art. Since this adjustment device allows the upper column to move and adjust relative to the lower column, even if there is a certain parallelism deviation in the initial processing and assembly, the hat cap can be adjusted to a suitable state, reducing product defects caused by parallelism errors, thereby reducing the product defect rate and improving product quality and production efficiency. The overall device only includes the upper column, the lower column, and the fixing component, with a relatively simple structure, which is convenient for manufacturing, installation, and use, reducing production costs and operational difficulty.

In addition, a brief explanation of the orientations involved in the following specific embodiments is provided: the directions or positional relationships indicated by "up," "down," "left," "right," "front," and "back" mentioned in the embodiments refer to the orientations or positional relationships shown in the accompanying drawings.

[0032] like Figures 1-7 As shown, this utility model relates to a height adjustment device for a hat cover, including an upper column 1, a lower column 2, and a fixing component 3. The upper column 1 is connected to the hat cover (not shown in the figure) and is located above the lower column 2. The lower column 2 is set on a platform (not shown in the figure) for installing various angular components. The fixing component 3 is set on the upper column 1 and the lower column 2. The upper end of the lower column 2 is provided with a second inclined surface 23. The upper column 1 moves a certain displacement along the second inclined surface 23, such as... Figure 3 As shown by the arrow (front and back), the height of the cap can be adjusted by fixing it with a fixing component, thereby reducing the product defect rate.

[0033] Preferably, the lower end of the upper post 1 is provided with a first inclined surface 13, and the first inclined surface and the second inclined surface are parallel. This arrangement increases the contact area between the first inclined surface and the second inclined surface, and improves the stability of the hat cover height adjustment. Specifically, the first inclined surface moves on the second inclined surface, thereby changing the height of the upper post and adjusting the height of the hat cover that connects to the upper post.

[0034] Preferably, the angle between the first inclined plane and the second inclined plane and the horizontal plane is 30~60°.

[0035] More specifically, the upper column 1 is provided with a first hole 11, which is close to the first inclined surface 13, and the fixing component 3 is connected to the upper column through the first hole 11.

[0036] More specifically, the upper end of the upper post 1 is provided with a groove 12, which facilitates connection with the cap.

[0037] More specifically, the lower end post 2 is provided with a second hole 21 and a third hole 22. The second hole 21 is located above the third hole 22 and is close to the second inclined surface 23.

[0038] Preferably, the lower end post 2 has an L-shaped structure, which not only facilitates the fixing of the lower end post, but also improves the stability of the lower end post connection.

[0039] Specifically, the fixing component 3 includes a support part 31 and a tightening part 32. The support part 31 is connected to the tightening part 32. The support part 31 limits and supports the upper column 1, specifically limiting the movement of the first inclined plane on the second inclined plane. The tightening part 32 fixes the upper column.

[0040] Preferably, two support parts 31 and two tightening parts 32 are provided, and the two support parts and two tightening parts are alternately connected to form a frame structure. This arrangement not only improves the stability of the lower column, but also effectively limits the movement of the upper column.

[0041] More specifically, one end of the support part 31 is movably connected to the lower column 2, and the other end of the support part 31 is fixedly connected to the upper column 1. This arrangement allows the lower column to move relative to the support part when the support part is stable.

[0042] More specifically, the lower end of the support part 31 is fixed to the lower end column, and the upper end of the support part 31 is movably connected to the upper end column.

[0043] Specifically, the support part 31 includes a first support plate 311, which is located on the left and right sides of the first inclined surface. The lower end of the first support plate 311 is fixed to the lower end column, and the upper end of the first support plate 311 is movably connected to the upper end column 1.

[0044] More specifically, the first support plate 311 is provided with a first through hole 312, a second through hole 313, a third through hole 314, a fourth hole 315, a first fastener 316, a second fastener 317, and a third fastener 318. The first through hole 312 is an inclined track hole, and the inclination of the first through hole is consistent with the inclination of the first inclined surface / second inclined surface. The third through hole 314 is located between the first through hole 312 and the second through hole 313, and the third through hole is close to the first inclined surface. The first fastener 316 is inserted into the first through hole 312 and connected to the upper end post 1. The second fastener 317 is inserted into the second through hole 313 and connected to the lower end post 2. The fourth hole 315 is a bolt hole located on the front and rear sides of the upper end of the first support plate, and is used to fix the support part and the tightening part.

[0045] More specifically, the first fastener 316 is inserted into the first through hole and the first hole 11 in sequence to connect the first support plate and the upper column. The first through hole limits the first fastener, thereby allowing the upper column to move within a certain range. The second fastener 317 is inserted into the second through hole and the third hole 22 in sequence to connect the first support plate and the lower column. The third fastener 318 is inserted into the third through hole and the second hole in sequence to connect the first support plate and the lower column, thereby improving the connection firmness.

[0046] Preferably, the first fastener, the second fastener, and the third fastener are all screws.

[0047] Specifically, the tightening part 32 includes a second support plate 321, which is a cuboid structure. The second support plate 321 is located on the front and rear sides of the first inclined surface. The second support plate 321 is fixedly connected to the first support plate 311 and movably connected to the upper column 1.

[0048] More specifically, the second support plate 321 is provided with a fourth through hole 322, a fifth through hole 323, a fifth hole 324, a fourth fastener 325, a fifth fastener 326, and a sixth fastener (not shown in the figure). The fourth fastener 325 is inserted into the fourth through hole 322 and contacts the upper end post 1. The fifth fastener 326 is inserted into the fifth through hole 323 and the fourth hole 315 in sequence to realize the fixed connection between the first support plate and the second support plate. The fifth hole 324 is located on the left and right sides of the second support plate, and the fifth hole 324 communicates with the fourth through hole 322 and their circular axes are perpendicular. After the sixth fastener is inserted into the fifth hole, the fourth fastener is tightened.

[0049] Preferably, there are two fourth fasteners and two sixth fasteners, and four fifth fasteners, located around the second support plate.

[0050] Specifically, the fourth and fifth fasteners are screws, and the sixth fastener is a set screw. When the first inclined surface of the upper post moves along the second inclined surface and is simultaneously limited by the first through hole, it is moved to the appropriate position, and then the upper post is fixed with screws and tightened with set screws.

[0051] This utility model also relates to a sock machine, including the height adjustment device described above.
