Technical Field
[0001] The utility model relates to the technical field of sewing equipment, in particular to an adjustable anti-cloth jamming device for a sewing needle plate. Background Art
[0002] With the development of the economy, people's demands for clothing are becoming more and more diverse, and the textile industry is developing rapidly. According to the styles and fabrics of clothing, various different sewing equipment is required.
[0003] In clothing production, a herringbone sewing machine is often used to sew decorative stitches to improve the overall image and high-grade quality of clothing. It can be used for processes such as herringbone stitch splicing, pressing lines, and hemming. Since the herringbone sewing machine needle plate is in the shape of a long groove, when sewing net fabric or very thin fabrics, the fabric is often jammed (the needle plate holes are very long and do not match the stitch span, resulting in the fabric being brought under the needle plate), which causes the clothes to be damaged and even damages the machine. Therefore, when operating, the operator must hold both sides of the fabric with both hands and feed the fabric forward at the same time. It can only be said that the frequency of cloth jamming is slightly reduced, but it still causes damage to the fabric and the equipment. Moreover, the uneven feeding of the fabric will also result in uneven stitches, the quality cannot be guaranteed, and the process requirements of customers cannot be met. Therefore, there is a need for improvement. Summary of the Utility Model
[0004] The utility model provides an adjustable anti-cloth jamming device for a sewing needle plate, which can adaptively adjust the length of the needle plate holes according to the stitch span, effectively avoid the situation of cloth jamming, and greatly improve the work efficiency and the quality of finished products; it solves the technical problem in the prior art that the needle holes of the current herringbone sewing machine needle plate do not match the stitch span, cannot be adapted or adjusted according to the requirements, and are prone to the situation of fabric jamming, affecting the quality of finished products.
[0005] The above technical problem of the utility model is solved by the following technical solution: An adjustable anti-cloth jamming device for a sewing needle plate includes a workbench, a sewing device is arranged above the workbench, the surface of the workbench is embedded with a needle plate, a feeding groove is opened on the surface of the needle plate, a feeding protrusion is arranged in the feeding groove, a needle groove is opened in the middle of the needle plate, an adjusting plate is slidably arranged on the needle plate, a groove is opened on the adjusting plate, and the width of the exposed part of the needle groove is adjusted by the sliding of the adjusting plate and the groove. Before sewing, move the adjusting plate back and forth according to the span of the needle thread stitch to adjust the width of the exposed part of the needle groove. The groove on the adjusting plate fits well with the needle groove and the span height of the needle thread stitch, which can effectively prevent the fabric from being caught under the needle plate and ensure the work efficiency and the quality of finished products; the utility model can adapt to herringbone sewing with different spans, can adaptively adjust the length of the needle plate holes according to the stitch span, and can prevent cloth jamming at the same time.
[0006] Preferably, the groove is a V-shaped groove. The V-shaped grooves are symmetrically arranged in the middle of the adjusting plate. As the adjusting plate moves back and forth, the width of the exposed part of the needle groove can be adjusted according to the required span of the needle thread trace.
[0007] Preferably, the needle groove is a horizontal groove and the feeding groove is a vertical groove.
[0008] Preferably, the adjusting plate is a Y-shaped plate and slides in the gap between the feeding grooves. The shape of the adjusting plate of the present utility model is set according to the position of the feeding grooves. The Y-shaped adjusting plate can move back and forth in the gap between the feeding grooves without affecting the up-and-down feeding of the feeding protrusions.
[0009] Preferably, the adjusting plate and the feeding protrusions do not contact each other. The length of the feeding protrusions is adaptively shortened according to the forward and backward movement positions of the adjusting plate to avoid contact and collision between the feeding protrusions and the adjusting plate during feeding.
[0010] Preferably, a fixing groove is provided at the tail of the adjusting plate, and a fixing bolt is provided in the fixing groove. The fixing bolt can move in the fixing groove and be fixed and locked on the workbench.
[0011] Preferably, an adjusting sliding groove is provided on the surface of the workbench, and the adjusting plate slides along the adjusting sliding groove. The adjusting sliding groove can play a guiding role for the sliding of the adjusting plate to ensure the vertical movement of the adjusting plate.
[0012] Preferably, scales are provided in the adjusting sliding groove. Before sewing, adjust by moving the adjusting plate back and forth according to the span of the needle thread trace. Adjust the adjusting plate to the corresponding scale position in the adjusting sliding groove according to the needle span to ensure that the exposed width of the needle groove is consistent with the required needle span.
[0013] Preferably, the surface of the feeding protrusions is provided with patterns. The patterns on the surface of the feeding protrusions are used to increase the friction with the fabric to achieve feeding, and the pattern style can be adjusted according to actual needs.
[0014] Preferably, the size of the feeding protrusions is smaller than the size of the feeding grooves. The feeding protrusions will reciprocate obliquely forward during feeding, and the fact that the size of the feeding protrusions is smaller than the size of the feeding grooves can prevent the feeding protrusions from colliding with the adjusting plate and ensure the normal feeding of the feeding protrusions.
[0015] Therefore, an adjustable anti-cloth jamming device for a sewing needle plate of the present utility model has the following advantages: it can adaptively adjust the length of the needle plate holes according to the thread trace span, effectively avoid the situation of cloth jamming, greatly improve the working efficiency and enhance the finished product quality.
