TECHNICAL FIELD

[0001] The utility model relates to embroidery positioning field, concretely is a kind of embroidery positioning device of embroidery machine. BACKGROUND

[0002] In the textile embroidery industry, embroidery quality and efficiency have been the core of enterprise attention. With the growing demand for diversification and refinement of embroidered products, the performance of embroidery machines and the precision of supporting devices become increasingly critical. As an important part of embroidery machine, the performance of embroidery positioning device directly affects the accuracy and consistency of embroidery pattern.

[0003] Traditional embroidery machine has many deficiencies in cloth positioning. Some early positioning devices use simple mechanical clamps, which are fixed by manual tightening. This method is not only cumbersome to operate, but also consumes a lot of manpower and time. Due to the difference of manual operation, it is difficult to ensure the consistency of the tightness of the cloth fixed each time, which leads to problems such as displacement and wrinkles of the cloth during the embroidery process, seriously affecting the quality of the embroidered pattern and increasing the rate of defective products. Therefore, we propose a kind of embroidery positioning device of embroidery machine. SUMMARY

[0011] Preferably, when the tension spring is not subjected to tension, the lower end of the pressing plate is inserted into the inside of the arc-shaped groove.

[0012] Compared with the prior art, the embroidery positioning device of the embroidery machine has the following beneficial effects:

[0013] 1. The embroidery positioning device of the embroidery machine, by cooperation of the top pressing frame and the bottom bearing frame, utilizes the spring assembly to pull the top pressing frame to move downward, so that the pressing plate presses the cloth into the arc-shaped groove, and the cloth can be effectively fixed straight. This fixing mode can ensure that the cloth always maintains a flat and tight state during the embroidery process, avoids wrinkles caused by loose cloth, and further improves the clarity and accuracy of the embroidered pattern, and reduces the rate of defective products.

[0014] 2.

This shape can better fit the cloth and adapt to the fixing needs of cloths of different materials and thicknesses. Whether it is light silk or thick denim, the device can realize stable fixing, widening the range of applicable cloths of the embroidery machine.

[0015] 3. The embroidery positioning device of the embroidery machine, the device has a double sliding rail structure in the longitudinal and transverse directions. The cooperation of the connection of the sliding table one and the sliding block one on the longitudinal sliding rail and the connection of the sliding table two and the sliding block two on the transverse sliding rail realizes flexible sliding of the bottom bearing frame in the longitudinal and transverse directions. The operator can accurately control the movement in the two directions to accurately position the cloth in the two-dimensional plane, meet the accurate requirements of complex embroidery patterns on the position of the cloth, and make each part of the embroidery pattern accurately embroidered on the specified position of the cloth.

The spring assembly can automatically fix the cloth, the operation is simple and fast, and there is no need for complex fastening steps, which greatly saves the time for clamping the cloth and improves the production efficiency. Compared with the traditional manual fastening mode, the manual operation time and labor intensity are greatly reduced.

[0017] 5、The embroidery positioning device of the embroidery machine, the precise design and cooperation of the sliding rail and the sliding block ensure the stability and smoothness when adjusting the position of the cloth. The guiding effect of the sliding groove on the sliding block, as well as the firm connection of the connecting sliding table and the sliding rail, and the bearing frame, reduces the shaking and deviation during movement, further improving the accuracy of positioning. Even in the process of high-speed embroidery, the cloth can maintain a fixed position, ensuring the consistency of the embroidery quality. BRIEF DESCRIPTION OF DRAWINGS
