Technical Field
[0001] This utility model relates to the field of garment manufacturing equipment technology, and in particular to an intelligent tube-type cover-up sewing machine. Background Technology
[0002] In the current stage of garment manufacturing, when traditional tubular coverstitch machines are used to sew elastic bands onto trousers, operators need to use a regular sewing machine to initially fix the elastic band along the waistband of the trousers to create a positioning stitch. The trousers with the elastic band fixed are then transferred to the tubular coverstitch machine for secondary sewing reinforcement. This process relies on manual positioning and multiple clamping and transfer operations. With the increasing demand for automation and high-efficiency production in the garment manufacturing industry, more optimized technical solutions are needed to upgrade the sewing process. Existing tubular coverstitch machines rely on manual labor to initially attach elastic bands to trousers using a regular sewing machine. This process is not only labor-intensive and time-consuming, but also inefficient. Furthermore, the lack of tension control devices leads to uneven tension in the elastic band during sewing, resulting in inconsistent elastic band tightness and surface wrinkles. Due to the absence of an effective limiting structure, operators must pause after sewing a quarter turn to manually straighten the elastic band and trousers, further reducing production efficiency and compromising the consistency of sewing quality. Therefore, we propose an intelligent tubular coverstitch machine to address these problems. Utility Model Content

[0017] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.
[0018] Example 1, refer to Figure 1-4 In this embodiment, to address the problem that existing tubular coverstitch machines rely on manual labor to initially fix the elastic band to the trousers using a regular sewing machine, a process that is not only labor-intensive and time-consuming but also inefficient, the lack of a tension control device leads to uneven tension in the elastic band during sewing, resulting in inconsistent elastic band tightness and surface wrinkles. Furthermore, due to the absence of an effective limiting structure, operators must pause after sewing a quarter turn to manually straighten the elastic band and trousers, further reducing production efficiency and compromising the stability of sewing quality.

[0019] The tension adjustment mechanism 5 includes a limiting guide roller 51 and a second adjustment device 52. The rear end of the bearing plate 3 is bent downward. The second adjustment device 52 is fastened to the back of the mounting part of the bearing plate 3 by a bolt group. A second limiting roller 53 is provided on the left side of the second adjustment device 52. The limiting guide roller 51 is installed on the mounting part of the bearing plate 3 by fastening bolts and can rotate around the axial direction.

The first return spring 45 provides elastic force to the first sliding support 411, thereby achieving the purpose of adjusting the pressure of the first limiting roller 41 on the fabric.
[0021] The first adjusting slider 43 is fastened to the first limiting seat 42 by the first adjusting bolt 44. The first sliding support 411 is movably installed in the first limiting seat 42. The first limiting roller 41 is axially connected to the left side of the first sliding support 411. The first sliding support 411 is located at the lowest position of the first limiting seat 42.

The second adjusting slider 522 is fastened to the second limiting seat 521 by the second adjusting bolt 523, and the second return spring 524 is fastened to the top of the second adjusting slider 522. Between the second sliding support 531 and the second sliding support 531, a second adjusting device 52 is installed. This device consists of the second sliding support 531, the second limiting seat 521, the second adjusting slider 522, the second adjusting bolt 523, and the second return spring 524. By utilizing the sliding fit between the second guide groove 5211 inside the second limiting seat 521 and the second adjusting slider 522, and by coordinating the second adjusting bolt 523 to adjust the vertical position of the second adjusting slider 522, and by using the elastic force applied to the second sliding support 531 by the second return spring 524, the tension of the fabric by the second limiting roller 53 is adjusted, thus achieving real-time adjustment of the fabric tension.
[0023] The limiting guide roller 51 is axially movably installed directly above the mounting part of the bearing plate 3. The limiting guide roller 51 is in tangential contact with the outer circumferential surface of the second limiting shaft roller 53. The surface of the friction-reducing guide slider 21 is coated with a low friction coefficient coating to reduce the sliding resistance of the sewing material. By axially movably installing the limiting guide roller 51 on the mounting part of the bearing plate 3 and making it tangentially contact the outer circumferential surface of the second limiting shaft roller 53, a stable tension control node can be formed during the fabric conveying process, realizing the coordinated adjustment of the fabric tension. The low friction coefficient coating on the surface of the friction-reducing guide slider 21 effectively reduces the resistance when the sewing material slides, reducing the jamming phenomenon during the fabric conveying process.
[0024] A fastening wing 31 is integrally formed on the right side of the support plate 3. The fastening wing 31 is fastened to the head of the sewing main body 2 by bolts. The vertical position of the first adjusting slider 43 in the first limiting seat 42 is controlled by adjusting the tightness of the first adjusting bolt 44, thereby adjusting the elastic pressure of the first return spring 45, and thus adjusting the pressure applied to the surface of the sewing material by the first limiting roller 41. The vertical position of the second adjusting slider 522 in the second limiting seat 521 is controlled by adjusting the tightness of the second adjusting bolt 523, thereby adjusting the elastic pressure of the second return spring 524, and thus... The pressure applied to the sewing material surface by the second limiting roller 53 is adjusted by fastening the fastening wing 31 integrally formed on the right side of the bearing plate 3 to the head bolt of the sewing main body 2, thus achieving a stable assembly of the device and the main body. The vertical position of the first adjusting slider 43 in the first limiting seat 42 is precisely controlled by the first adjusting bolt 44. With the adjustment of the elastic pressure of the first return spring 45, the pressure applied to the first limiting roller 41 can be flexibly adjusted. The pressure of the second limiting roller 53 on the sewing material is precisely adjusted by the control of the second adjusting slider 522 by the second adjusting bolt 523 and the synergistic effect of the second return spring 524.
[0025] The dual-stage tension equalization control mechanism assisted by the guide plate 6: In the actual sewing process, the sewing material and elastic webbing are first flipped at a small angle by the guide plate 6 to change their initial conveying direction and position, so that the two are more closely attached. Then, with the cooperation of the limiting guide roller 51 and the second limiting shaft roller 53, a rear tension control node is formed, while the front first limiting shaft roller 41 and the friction-reducing guide slider 21 constitute the front tension control combination. The two sets of components work together to apply a balanced and stable force to the sewing material and elastic webbing. When the sewing material and elastic webbing pass through the above area, by accurately setting the pressure and position of each component, problems such as wrinkles and uneven tightness caused by uneven tension are avoided.
[0026] The specific working principle is as follows: By installing a multi-level tension control system consisting of a first adjusting device 4, a second adjusting device 52, and a limiting guide roller 51, and in conjunction with the flexibly adjustable first limiting roller 41 and second limiting roller 53, dynamic adjustment of the elastic band and fabric tension during sewing is achieved. The low-friction coefficient coating on the surface of the friction-reducing guide slider 21 reduces the sliding resistance of the material, thereby achieving the purpose of controlling sewing tension and reducing manual intervention. The fastening wing 31, which is integrally formed by the bearing plate 3, is bolted to the sewing main body 2 to build a stable assembly structure, ensuring the stability of equipment operation. The first adjusting bolt 44 and the second adjusting bolt 523 are used to control the vertical position of the corresponding adjusting slider, and the pressure applied to the limiting roller is flexibly adjusted in conjunction with the return spring to meet the needs of different sewing materials and processes, thereby improving the versatility of the equipment and simplifying the installation and maintenance process.
[0027] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
