Cutting device for processing flexible materials

Abstract

The invention relates to a cutting device for processing flexible materials. The cutting device comprises a supporting body (8) which is fixedly provided with a shell cover (9), wherein a cutting knife rod (7) is mounted at the supporting body (8) in a sliding manner and comprises a cutting knife head (72), a dent (71), a right side convex part (76), a left side convex part (75) and an engaging end part (77); the cutting knife head (72) is arranged at the left end and is used for cutting, the dent (71) is formed in the upper side surface of the cutting knife rod (7), the right side convex part (76) and the left side convex part (75) are located on the lower side surface of the cutting knife rod (7), and the engaging end part (77) is located at the right end, and is engaged with the shell cover (9); the engaging end part (77) is further engaged with an up-pressing elastic component (770) so as to prop the engaging end part (77) of the cutting knife rod (7) against the shell cover (9); a wedge-shaped board (73) which can slide up and down and is upwards pressed to press the cutting knife rod (7) by an elastic up-pressing spring (74) is arranged corresponding to the dent (71) in the supporting body (8).

Description

technical field [0001] The invention relates to a material processing device, in particular to a cutting device, such as a cutting device for soft materials. Background technique [0002] Cutting devices are widely used in the field of material processing. The cutting device often adopts the reciprocating motion of the blade to complete the cutting of the material. [0003] However, during the cutting process, the cut material often leaves weak residual connection parts after the cutting is completed. This has a detrimental effect on the processing quality as well as on subsequent processing steps. Especially for cutting soft materials with a certain degree of elasticity, it is not easy to completely cut off the material due to the slow movement of the blade at a small position, resulting in material residues. [0004] However, if simply adding equipment performance to the cutting device, such as increasing the running speed and cutting force of the blade, this will signi...

[0003] However, during the cutting process, the cut material often leaves a weak residual connection after the cutting is completed.

This adversely affects the processing quality as well as subsequent processing steps

Especially for cutting soft materials with a certain degree of elasticity, it is not easy to completely cut off the material due to the slow movement of the blade at a small position, resulting in residual material

[0004] However, if the equipment performance is simply increased to the cutting device, such as increasing the operating speed and cutting force of the blade, this will significantly increase the cost and increase the complexity of the equipment, which is not conducive to maintenance
