Description

Technical Field

[0001] The utility model relates to the technical field of leather shoe fabric cutting mechanisms, and more particularly to a leather shoe fabric cutting mechanism. Background Art

[0002] In the existing leather shoe fabric cutting technology, there are some limitations and inconveniences in the design and operation of the cutting mechanism. First, the traditional cutting mechanism usually relies on fixed blades when cutting leather shoe fabrics. The angles and positions of these blades are often preset and cannot be adjusted according to different cutting requirements or fabric characteristics. This fixed setting limits the flexibility and adaptability of cutting, which may lead to poor cutting effects or inefficiency.

[0003] Secondly, some existing cutting mechanisms use single-sided conveying rollers when conveying leather shoe fabrics. This simple conveying structure may cause wrinkles or deformation of the fabric during the conveying process. Wrinkles not only affect the accuracy of cutting, but may also cause damage to the fabric, affecting the quality and appearance of the final product.

[0004] In addition, the existing cutting mechanism also has inconveniences in replacing blades. Since the blades cannot be flexibly disassembled and assembled, the process of replacing blades may be time-consuming and laborious, which not only increases the time for maintenance and repairs, but may also affect the normal operation of the production line. Especially when the blades are worn or damaged, the inability to replace them quickly will cause production interruptions, affecting production efficiency and output. Utility Model Content

After the replacement is completed, push the matching sleeve 8 so that the matching The matching sleeve 8 drives the matching rod 12 and the matching plate 14 to slide along the guide rail 25 and the guide groove 26. At the same time, the matching sleeve 8 cooperates with the adapter sleeve 13 to squeeze the second push spring 32. When the second push spring 32 is squeezed to the limit, the matching plate 14 just passes through the circular groove 16 and moves to the other side of the adapter sleeve 13. Then the adapter sleeve 13 is released, and the spring 6 pushes the return block 7 to reset. Then the return block 7 will drive the adapter sleeve 13 to reset. Then the adapter sleeve 13 will drive the arc groove 15 and the circular groove 16 to reset. Then the matching rod 12 will enter the arc groove 15.
