Cutoff knife mechanism of cutting machine and cutting machine

Abstract

The invention relates to a cutoff knife mechanism of a cutting machine and a cutting machine with the cutoff knife mechanism. The cutoff knife mechanism comprises a knife handle, a cutoff knife body and a floating rod assembly, wherein the floating rod assembly is arranged in the knife handle and is used for connecting the cutoff knife body; the floating rod assembly comprises a floating part; an accommodating cavity for accommodating the floating part is arranged in the knife handle; the floating part of the floating rod assembly is arranged in the accommodating cavity in a sliding manner and is used for driving the cutoff knife body to carry out reciprocating motion on the table vertical to the cutting machine; a first gas path and a second gas path communicated with the accommodating cavity are also arranged in the knife handle; and the cutoff knife mechanism of the cutting machine also comprises an air supply device for supplying the first gas path or the second gas path with air and a valve element arranged in the knife handle for opening the first gas path or the second gas path. Compared with the prior art, the cutoff knife mechanism has the advantages that high-frequency oscillatory motion of the cutoff knife body is directly achieved through a pneumatic mode, so that a drive device adopting a motor transmission device as the cutoff knife mechanism is omitted and the production cost of the whole cutoff knife mechanism and the whole cutting machine is greatly reduced.

Description

technical field [0001] The invention relates to a cutting machine, in particular to a cutting machine knife mechanism and a cutting machine with the cutting knife mechanism. Background technique [0002] At present, in some leather cutting, cloth cutting and other industries, materials are often cut according to the needs of production, and modern people have higher and higher requirements for cutting technology, and high-speed efficiency is also required while pursuing high-quality cutting. For example, cutting out different shapes, different angles, and different lengths of cloth or leather requires manual cutting by workers in many cases. It is difficult to guarantee the quality of cutting, and the efficiency is relatively low. Therefore, in order to overcome this defect, the cutting machine was born And born. [0003] As a precision instrument for cutting materials such as cloth and leather, the cutting machine has been widely used in some leather and cloth industries d...

Problems solved by technology

Among them, the working method of the vibrating knife is to drive the knife to reciprocate continuously up and down through a transmission mechanism such as a motor, so as to realize the high-frequency oscillation of the knife on the material, thereby completing the cutting of the material, but because the overall structure of the vibrating knife is very complicated, As a result, its production and assembly costs are too expensive, especially in order to realize the high-frequency reciprocating motion of the cutter head, the cost of its motor drive device and transmission mechanism is even higher

In addition, in order to realize the control of the motor speed, it is necessary to add an additional set of main control system for controlling the motor speed, which further increases the production cost of the cutting machine.
