Cutting device of tape handler

Abstract

The invention relates to a cutting device of a tape handler. The cutting device comprises a wall plate, an upper cutter assembly, a lower cutter assembly and a motor assembly, wherein the upper cutter assembly, the lower cutter assembly and the motor assembly are connected to the wall plate; the motor assembly comprises a servo motor and a motor base; the upper cutter assembly is connected with an upper cutter gear; the position, corresponding to the upper cutter gear, of the lower cutter assembly is connected with a lower cutter gear; one end of the lower cutter assembly is connected with a synchronous wheel; the motor assembly is connected with the synchronous wheel through a transmission part and can drive the synchronous wheel to rotate so as to drive the lower cutter assembly to rotate, so that the lower cutter assembly and the upper cutter assembly rotate relatively; the upper cutter assembly comprises an upper cutter shaft, a cutter and a cutter pressing plate; the cutter is connected to the upper cutter shaft through the cutter pressing plate; and the lower cutter assembly comprises a lower cutter shaft and a cutter seat arranged in the lower cutter shaft. The cutting device of the tape handler is high in response speed, high in production efficiency and simple in structure.

Description

Technical field: [0001] The invention relates to the technical field of packaging bag processing equipment, in particular to a cutting device for a paper tape machine. Background technique: [0002] The cutting part cover is an extremely important mechanism in the paper tape machine production line. It is the cutting part cover of the paper bag machine. Its main function is to cut off the paper that has been folded into a barrel, and then proceed to the next step. During the cutting process, the cutter The line speed must be faster than the machine line speed, otherwise there will be paper piles, which will cause problems such as paper bag wrinkling. [0003] The cutting part sleeve in the prior art mainly realizes the acceleration and deceleration function through a purely mechanical structure. Specifically, by designing an elliptical gear, the acceleration and deceleration of the cutter at a specific position is realized by using the difference in curvature radius between ...

[0003] The cutting part sleeve in the prior art mainly realizes the acceleration and deceleration function through a purely mechanical structure. Specifically, by designing an elliptical gear, the acceleration and deceleration of the cutter at a specific position is realized by using the difference in curvature radius between the two elliptical gears meshed. The cut-off part of the structure has slower response and production speed
