Description

Technical Field

[0001] The utility model relates to the technical field of cutting processing, in particular to an automatic cutting mechanism for shoulder strap fabric. Background Art

[0002] Shoulder straps are an important structure in supporting underwear. Whether the underwear worn daily is comfortable often depends on the shoulder straps. During the processing, the shoulder straps of the underwear need to be cut to the specified length.

[0003] After searching, the existing Chinese patent with publication number CN202221777704.6 discloses a shoulder strap cutting device for underwear processing. By setting multiple shoulder strap rolls in the transmission component for simultaneous transmission and setting the cutting component, multiple shoulder strap rolls can be cut simultaneously to solve the problem that the shoulder straps are long and manual cutting is laborious, and the existing shoulder strap cutting is all single-strand cutting, which is not convenient for cutting multiple shoulder straps at the same time. The cutting knife can be raised and lowered, so that after the cutting is completed, the shoulder strap roll moves a certain length during the time the cutting knife is raised and lowered in mid-air, which is conducive to the cutting of the shoulder strap roll.

[0004] The above technical solution has the following defects: although such a shoulder strap fabric cutting mechanism is provided with multiple sets of automatic feeding structures, so that multiple shoulder strap rolls can be loaded and cut synchronously, in actual use, the shoulder strap fabric has a certain elasticity and is easy to deform during the cutting process. In order to ensure the flatness of the cutting incision and further improve the applicability, the equipment is suitable for shoulder strap fabrics of different widths. Now, an automatic shoulder strap fabric cutting mechanism is proposed, which can set multiple sets of limiting grooves according to the width of the shoulder strap fabric during cutting and transportation, so that multiple groups of shoulder strap fabrics of different widths can be loaded and cut synchronously, which has better applicability, and a limiting plate is provided to limit the cutting part of the shoulder strap fabric when the cutting machine is automatically cutting, thereby preventing the shoulder strap from deforming and improving the flatness of the incision.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and combines theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.
