[0024] Such as Figure 1 , Figure 2 And Figure 3As shown in the figure, a thread take-up spring stroke adjustment device for an embroidery machine adjustment table includes an adjustment table 1 and a plurality of thread take-up spring stroke adjustment components 2. An installation seat 11 corresponding to the thread take-up spring stroke adjustment component 2 one by one is provided on the adjustment table 1. An installation hole 111 is provided on the installation seat 11, and a first tooth-shaped structure 112 is provided at a preset position around the installation hole 111;

[0025] The thread take-up spring stroke adjustment component 2 includes a support column 21, a thread take-up spring adjuster 22, a thread take-up spring 23, a pressing member 24, a spring 25, a mounting cap 26, and a mounting cap mounting member 27. The support column 21 is inserted into the installation hole 111 and fixedly connected to the bottom of the adjustment table 1. A second tooth-shaped structure 221 is provided at the bottom of the thread take-up spring adjuster 22. The thread take-up spring adjuster 22 is sleeved on the support column 21 and meshed and connected with the first tooth-shaped structure 112 through the second tooth-shaped structure 221. The thread take-up spring 23 is sleeved on the support column 21, and the thread take-up end of the thread take-up spring 23 passes through the thread take-up spring adjuster 22. The pressing member 24 is sleeved on the support column 21, and one side of the pressing member 24 abuts against the side of the thread take-up spring adjuster 22 away from the first tooth-shaped structure 112. The mounting cap mounting member 27 is sleeved on the support column 21. The spring 25 is sleeved on the support column 21, and both ends of the spring 25 abut against the pressing member 24 and the mounting cap mounting member 27 respectively. The mounting cap 26 is mounted on the mounting cap mounting member 27, and the spring 25 is always in a compressed deformation state.

[0026] The thread take-up spring adjuster 22 is made of plastic material. The thread take-up end 231 of the thread take-up spring 23 passes through the thread take-up spring adjuster 22. The thread take-up spring adjuster 22 can drive the thread take-up spring 23 to move, so that the thread take-up end 231 of the thread take-up spring 23 is in a preset position. The thread take-up spring adjuster 22 in the prior art is usually made of metal material, and it is easy to damage the thread take-up spring 23 when contacting the thread take-up spring 23 for a long time. The thread take-up spring adjuster 22 of the present application is made of plastic material, which can effectively avoid damaging the thread take-up spring 23 during long-term contact. The spring 25 is always in a compressed deformation state, so the spring 25 always presses the pressing member 24, so that the pressing member 24 elastically presses the thread take-up spring adjuster 22 on the installation seat 11, so that the first tooth-shaped structure 112 and the second tooth-shaped structure 221 are always in a meshed state.

[0027] When it is necessary to adjust the stroke of the wire take-up spring 23, rotate the wire take-up spring adjusting member 22 to a preset position, and the position and stroke of the wire take-up spring 23 can be adjusted. Since the spring 25 is always in a compressed deformation state, the spring 25 always elastically presses the wire take-up spring adjusting member 22 against the mounting seat 11 through the pressing member 24, so that the wire take-up spring adjusting member 22 and the mounting seat 11 will not separate, and the first tooth-shaped structure 112 and the second tooth-shaped structure 221 are always in a meshed state, so that the wire take-up spring adjusting member 22 and the mounting seat 11 will not move easily without external force rotation, making it easier to adjust the position and stroke of the wire take-up end 231 of the wire take-up spring 23.

[0028] In this way, in an embroidery machine adjustment table wire take-up spring stroke adjustment device, through the cooperative setting of the adjustment table 1 and a plurality of wire take-up spring stroke adjustment components 2, the wire take-up spring stroke adjustment component 2 includes a support column 21, a wire take-up spring adjusting member 22, a wire take-up spring 23, a pressing member 24, a spring 25, a mounting cap 26 and a mounting cap mounting member 27. Under the action of the spring 25, the mounting seat 11 and the wire take-up spring adjusting member 22 are meshed and connected through the first tooth-shaped structure 112 and the second tooth-shaped structure 221. When it is necessary to adjust the stroke of the wire take-up spring 22, manually rotate the wire take-up spring adjusting member 22, and then drive the wire take-up end 231 of the wire take-up spring 23 to move to a preset position, and the stroke adjustment of the wire take-up spring 23 can be completed, which is simple and convenient, and effectively reduces the workload.

[0029] In one of the embodiments, the wire take-up spring stroke adjustment component 2 further includes a wave washer 28. The wire take-up spring adjusting member 22 has a receiving groove 222, and the wave washer 28 is sleeved on the support column 21 and received in the receiving groove 222.

[0030] In this way, the receiving groove 222 is a "U"-shaped groove. When it is necessary to adjust the stroke of the wire take-up spring 23, because the first tooth-shaped structure 112 and the second tooth-shaped structure 221 are always in a meshed state, during the process of rotating the wire take-up spring adjusting member 22, the wire take-up spring adjusting member 22 will generate a certain amplitude of displacement in the axial direction of the support column 21. At this time, the wave washer 28 is provided, which can play a certain elastic buffering role.

[0031] In one of the embodiments, the wire take-up spring stroke adjustment component 2 further includes a snap ring 29. The support column 21 has an annular snap ring receiving groove 211, and the snap ring 29 is sleeved on the annular snap ring receiving groove 211 and its two ends are respectively abutted against the wave washer 28 and the pressing member 24.

[0032] In this way, the edge of the extruded part 24 elastically extrudes the wire take-up spring adjusting part 22, and the snap ring 29 is sleeved in the annular snap ring accommodating groove 211, which can play a role in limiting the extruded part 24 and prevent the extruded part 24 from further moving towards the wire take-up spring adjusting part 22.

[0033] As Figure 4 and Figure 5 shown, in one of the embodiments, a limiting groove 113 is provided at a preset position of the first tooth-shaped structure 112, and a limiting part 223 is provided at the bottom of the wire take-up spring adjusting part 22. The wire take-up spring adjusting part 22 drives the limiting part 223 to move in the limiting groove 113 during rotation.

[0034] In this way, the wire take-up spring adjusting part 22 drives the limiting part 223 to move in the limiting groove 113 during rotation. When the limiting part 223 abuts against the inner edge of the limiting groove 113, the wire take-up spring adjusting part 22 cannot rotate, which plays a certain role in limiting the wire take-up spring adjusting part 22.

[0035] In one of the embodiments, a plurality of first notches 224 are provided on the wire take-up spring adjusting part 22.

[0036] In this way, when rotating the wire take-up spring adjusting part 22, fingers can be placed in the first notches 224, which is convenient for rotating the wire take-up spring adjusting part 22.

[0037] As Figure 6 shown, in one of the embodiments, a second notch 212 is provided on the support column 21, and stoppers 271 are symmetrically arranged on the mounting cap mounting part 27. The stoppers 271 are accommodated in the second notch 212.

[0038] In this way, by accommodating the stoppers 271 in the second notch 212, the mounting cap mounting part 27 is prevented from rotating on the support column 21.

[0039] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0040] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
