A kind of vibrating knife leather cutting equipment with non-damaging leather presser foot

Abstract

The invention discloses vibration cutter leather cutting equipment with a pressing foot incapable of damaging leathers. The equipment comprises a breathable absorbing felt, a movable cutter frame beam, a movable cutter base, the leather leveling and cutting assisting pressing foot, a cutting platform, a maintenance door and a base table; the breathable absorbing felt is fixedly embedded above thecutting platform to maintain on the same horizontal plane with the surface; compared with the prior art, the edges of leathers are pressed down through a leather pressing ring plate; through a slope surface, pressing the bottom, of a slow slope, an anti-friction universal rotating device reduces the friction and presses the leathers into a leather contact bottom surface to level the leathers to prevent arching; when a vibration cutter moves, an anti-friction roller is suffered from direction change force, so that a roller fixing column drives a horizontal rotating roller to rotate on the innerwall of a device outer shell to change the roller rolling direction; and all rollers on the leather contact bottom surface are in the same direction, so that the friction force can be reduced duringmoving, and the leather leveling and cutting assisting pressing foot is prevented from leaving obvious marks or damage on the surfaces of the leathers to cause the quality reduction of the leathers.

Description

technical field [0001] The invention belongs to the technical field of leather goods production equipment, and in particular relates to a leather cutting equipment with a vibrating knife that does not damage the leather presser foot. Background technique [0002] Leather is animal skin that has been tanned and tanned through various complicated and cumbersome processes. Leather from different sources and treated by different methods has its own special characteristics, and at the same time has properties such as resistance to corruption, waterproof and breathable, and is made of leather. Clothes and articles are divided into A, B, and C categories according to different sources of materials and processing techniques, which are accepted and respected by a wide range of people, and most of the products are medium and high-end products. [0003] Leather needs not only to be tanned, but also to be cut and then sewn. The cutting equipment is classified by knife cutting, generally...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a vibrating knife leather cutting device with no damage to the leather presser foot to solve the problem of leather like cowhide and goatskin. The leather is relatively hard, and the fan generates negative pressure through the air felt. When absorbing the leather, the entire surface of the leather cannot be completely absorbed. The leather does not have the entire surface attached to the surface of the air felt, and it will tend to arch according to the original shape of the leather. Due to the toughness of the leather, when the vibrating knife vibrates up and down to cut, the peaks of the arch will appear. Moving left and right under the action of pressure makes it easy for the blade to avoid the wave crest, and the leather is difficult to cut. It needs to be cut artificially. While increasing the workload, multiple cutting will lead to the waste of leather.
