Description

Technical Field

[0001] The utility model relates to the field of fabric laying machine manufacturing, and particularly relates to an automatic edge trimming device for an automatic fabric laying machine. Background Art

[0002] In the production process of fabrics, in order to cut the fabrics, an automatic fabric laying machine is often used to change the rolled fabrics into multi-layer flat fabrics. The automatic fabric laying machine can automatically complete the fabric laying work and can cut the laid fabrics. In the actual fabric laying process, due to the elastic characteristics of the fabrics, the phenomenon that the two sides of the fabrics are prone to curling occurs. When the curled fabrics are transported to the laying platform, manual flattening is still required on both sides before cutting, resulting in low work efficiency. To solve this problem, an automatic edge trimming device can be set on the fabric laying machine to flatten the curled fabrics. The automatic edge trimming device usually includes an edge trimming belt and a pulley for driving the belt to rotate, and a motor for driving the pulley to rotate needs to be additionally installed. This not only has a complex structure but also increases the manufacturing cost. Summary of the Invention

[0003] In order to solve certain or some technical problems existing in the prior art, the purpose of this application is to provide an automatic edge trimming device for an automatic fabric laying machine, which can automatically perform edge trimming operations on the curled fabrics, has a simple structure, does not require an additional driving motor, and has a low manufacturing cost.

[0004] To solve the above-mentioned existing technical problems, the purpose of this application is achieved by adopting the following technical solutions: An automatic edge trimming device for an automatic fabric laying machine includes a fabric feeding shaft, a slide rail provided on the fabric feeding shaft, a sliding piece provided on the slide rail, and a driving device provided at the end of the fabric feeding shaft to drive the sliding piece to slide. The driving device includes a driving member provided at the end of the fabric feeding shaft and a pulley provided at the end of the sliding piece and cooperating with the driving member. A sliding groove cooperating with the pulley is provided around the driving member. The sliding groove includes a V-shaped groove and a vertical groove connected end to end. The pulley slides along the V-shaped groove to drive the sliding piece to slide outwards for edge trimming operations. The fabric feeding shaft drives the sliding piece to rotate together. By using the cooperation between the pulley and the V-shaped groove, the rotation of the sliding piece is converted into a horizontal displacement relative to the fabric feeding shaft along the slide rail, so as to realize the automatic edge trimming operation of the sliding piece on the curled fabrics. The structure is simple, no additional driving motor is required, and the manufacturing cost is low.

[0005] Preferably, the slide rail includes an upper slide rail connected to the sliding piece and a lower slide rail connected to the fabric feeding shaft. The upper slide rail slides inside the lower slide rail. Upper retaining pieces are provided on both sides of the upper slide rail, and lower retaining pieces are provided on both sides of the lower slide rail. The upper retaining pieces slide inside the lower retaining pieces. The structure is simple and the manufacturing cost is low. By using the cooperation and sliding connection between the upper retaining pieces and the lower retaining pieces, the displacement direction of the sliding piece is limited.

[0006] Preferably, a flexible layer is provided on the outer wall of the sliding piece. The structure of the flexible layer is the same as that of the sliding piece and covers the outer wall of the sliding piece. This avoids direct contact between the sliding piece and the fabric, preventing the fabric from being scratched and playing a role in protecting the fabric.

[0007] Preferably, an end cover is provided at the outer end of the driving member. Through holes for passing through the transmission shaft are provided in the centers of the end cover, the driving member, and the cloth feeding shaft. The end cover and the driving member are fixed, and after the transmission shaft passes through the through holes, it is connected to the cloth feeding shaft to drive the cloth feeding shaft to rotate. The end cover protects the driving member and prevents foreign objects and fabric from entering the gap between the driving member and the cloth feeding shaft, which may cause the automatic cloth laying machine to stop working.

[0008] Preferably, isolation pieces are provided on both sides of the sliding piece. The sliding piece and the isolation pieces are of an integrally formed structure. The isolation pieces play a role in supporting the sliding piece, reducing the pressure of the sliding piece on the slide rail, and ensuring the normal operation of the edge turning; the integrally formed structure can increase the overall strength and is convenient for manufacturing.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] For the automatic edge turning device for an automatic cloth laying machine adopting the above technical solution, the cloth feeding shaft drives the sliding piece to rotate together. By using the cooperation of the pulley and the V-shaped groove, the rotation of the sliding piece is converted into a horizontal displacement relative to the cloth feeding shaft along the slide rail, thereby realizing the automatic edge turning operation of the sliding piece on the fabric hem. The structure is simple, there is no need to additionally install a driving motor, and the manufacturing cost is low. BRIEF DESCRIPTION OF THE DRAWINGS
