[0002] In the field of garment manufacturing, a template machine usually refers to a sewing equipment, which combines garment template technology for practical application. This template sewing machine can sew automatically according to a preset template, improving sewing efficiency and product quality.

[0003] Currently, the shrinkage rate of the fabric after sewing by the template machines on the market is poor, and obvious fold marks can be visually felt. To address this situation, garment manufacturers mostly adopt the method of laying horsehair interlining during sewing to solve the problem. Horsehair interlining has horsehair arranged in a horse-tail shape. When sewing, the horsehair is sewn into the fabric. The horsehair occupies a certain space and bears the tension of the sewing thread. After sewing is completed, the whole horsehair interlining is pulled out, which can prevent the fabric from wrinkling. This practice improves the sewing effect while reducing the production efficiency of workers and causing a large amount of material loss.

[0004] For those skilled in the art, how to improve the efficiency of sewing horsehair interlining and reduce material loss is a technical problem that needs to be solved currently. Summary of the Utility Model

Detailed implementation mode

[0036] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the automatic laying device and sewing equipment of horsehair interlining materials of the present utility model will be introduced and described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0037] The present utility model provides an automatic laying device for horsehair interlining materials, in combination with Figure 1 , Figure 2 , Figure 3 As shown, the automatic laying device for horsehair interlining materials includes a horsehair interlining disk 1 and a drive assembly 2, and the drive assembly 2 is used to drive the horsehair interlining disk 1 to rotate.

[0038] The horsehair interlining disk 1 includes a support body 11 and horsehair 12. The support body 11 is a rigid support structure that plays a bearing role. One end of the horsehair 12 is fixed to the support body 11 and the other end is suspended. The horsehair 12 forms a cantilever structure. The horsehair 12 has a certain toughness and can maintain its suspended state.

[0039] The support body 11 is installed on the rotating part of the drive assembly 2. The drive assembly 2 is used to drive the support body 11 to rotate, thereby driving all the horsehair 12 to rotate circularly around the axis. Whether the horsehair 12 rotates around a vertical rotating shaft or a horizontal rotating shaft, the moving direction of the horsehair 12 at a certain moment is the same as the moving direction of the fabric, that is, the moving direction of the horsehair 12 facing the sewing needle is the same as the moving direction of the fabric, and the moving direction of the horsehair 12 facing the sewing needle is perpendicular to the moving direction of the sewing needle.

[0040] The horsehair 12 is located between the fabric and the sewing thread. The horsehair 12 is used to be sewn by the sewing thread when sewing the fabric. The horsehair 12 is clamped between the fabric surface by the sewing thread. The horsehair 12 occupies a part of the space and is pulled out from the sewing thread after sewing is completed. The space originally occupied by the horsehair 12 is released, which can avoid wrinkles caused by the pulling of the sewing thread on the fabric.

[0041] In combination with Figure 12As shown, fabric A advances linearly in the direction of the arrow. When passing through sewing needle B, sewing thread C is sewn onto fabric A, forming segments of sewing thread on the fabric. The sewing thread includes upper thread C1 above the fabric and bobbin thread C2 below the fabric. During sewing, horsehair 12 is located below the fabric. Horsehair 12 rotates around axis D, and horsehair 12 is densely distributed in the circumferential direction. When horsehair 12 reaches directly below sewing needle B, it is in the same direction as the movement of fabric A. The sewing needle sews and presses a part of horsehair 12 onto the lower surface of the fabric, and the horsehair 12 sewn into the sewing thread occupies a part of the space of the lower sewing thread, allowing more thread to remain on the fabric. The fabric continues to translate, and horsehair 12 continues to rotate. The movement directions of both change, and the horsehair 12 originally sewn into the sewing thread is pulled out. Compared with the method of directly sewing without using horsehair, the method of using horsehair for sewing reduces the pulling effect of the sewing thread remaining on the fabric on the fabric, preventing the fabric from wrinkling and improving the sewing effect.

[0042] Since horsehair 12 is distributed in a circle, horsehair 12 is continuously and repeatedly applied to the fabric sewing process. Horsehair 12 is automatically sewn by the sewing needle while rotating and automatically pulled out from the sewing thread, achieving the effect of automatic laying of horsehair interlining material without manual intervention, improving the efficiency of horsehair interlining sewing; due to the periodic circular rotation of horsehair 12, horsehair 12 can be continuously recycled, reducing material loss.

[0043] Based on the above solution, the present utility model provides three specific setting forms of horsehair interlining disc 1 here:

[0044] The first type: As shown in combination Figure 8 As shown, horsehair 12 is fixedly installed radially on the outer edge of support body 11.

In this embodiment, the outer edge of support body 11 is set to be circular. The inner ends of horsehair 12 are fixed on the side wall of support body 11, and horsehair 12 radially extends around support body 11. The outer ends of horsehair 12 are cantilever ends for cooperating with the sewing thread.

[0045] The second type: As shown in the line Figure 9 As shown, support body 11 is provided with a hollow annular disc. Horsehair 12 is fixedly installed radially on the inner edge of support body 11. Horsehair 12 is arranged in a plane, and all horsehair 12 are located in the same horizontal plane; support body 11 rotates around a vertical rotating shaft, and horsehair 12 is perpendicular to the rotating shaft. In this embodiment, the inner edge of support body 11 is set to be circular. The outer ends of horsehair 12 are fixed on the side wall of support body 11, and horsehair 12 converges towards the center of the rotating shaft. The inner ends of horsehair 12 are cantilever ends for cooperating with the sewing thread.

[0046] The third type: combination Figure 10 As shown, the support body 11 is provided with a cylinder. One end of the support body 11 is fixedly installed with horsehair 12. The horsehair 12 is arranged in a cylindrical space. All the horsehair 12 is arranged horizontally and encloses a cylinder. The support body 11 rotates around a horizontal rotating shaft, and the horsehair 12 is parallel to the rotating shaft.

The second synchronous pulley 24 is used to drive the synchronous pulley shaft 25 to rotate. The horsehair lining plate 1 is fixedly installed on the synchronous pulley shaft 25, and the synchronous pulley shaft 25 drives the horsehair lining plate 1 to rotate around the rotating shaft.

[0048] The driving assembly 2 of the present utility model includes a mounting seat 26 and a fixing seat 27. The first synchronous pulley 23 and the second synchronous pulley 24 are rotationally assembled on the mounting seat 26. The synchronous pulley shaft 25 is rotationally assembled on the mounting seat 26. The second synchronous pulley 24 is installed on the synchronous pulley shaft 25. The mounting seat 26 is used to provide installation support for other components of the driving assembly 2.
