Problems solved by technology

[0004] However, the hob on the driven shaft of the above-mentioned hob is easily affected by the prepreg. When the moving direction of the prepreg deviates, the hob on the driven shaft and the hob on the driving shaft will be relatively deviated. Shift, and the blade will also be subject to a certain degree of wear

Abstract

The invention relates to the technical field of prepreg slitting processing, in particular to a prepreg slitting mechanism. The prepreg slitting mechanism comprises a support, a driving rotating shaft, a rotating driving piece for driving the driving rotating shaft to rotate, a sliding block arranged on the support in a sliding mode and a first linear driving piece for driving the sliding block tomove, wherein the driving rotating shaft is provided with a first annular cutter, a driven rotating shaft is provided with a second annular cutter arranged opposite to the first annular cutter, the driving rotating shaft is further provided with a first gear, and the driven rotating shaft is provided with a second gear meshing with the first gear when the first annular cutter and the second annular cutter get close to a cutting material piece. According to the prepreg slitting mechanism, the first gear and the second gear which mesh with each other are arranged on the driving rotating shaft and the driven rotating shaft, so that the driven rotating shaft can be driven to rotate through meshing of the gears when the driving rotating shaft rotates, in this way, compared with the prior art,the friction force between prepreg and blades in the conveying process is greatly reduced, and the influence of friction force on a hob on a rolling shaft is reduced.

Description

technical field [0001] The invention relates to the technical field of prepreg cutting and processing, in particular to a prepreg cutting mechanism. Background technique [0002] Prepreg slitting refers to pulling the front end of the prepreg through the friction roller when handling the thin prepreg board, and then in order to better meet the requirements of various widths of the automatic wire laying machine, it is necessary to cut the width The web prepreg is cut into several strips of narrow strip prepreg according to a certain size, and then coated with a film layer and rolled up for use. [0003] In related technologies, hob cutting is often used for prepreg cutting, that is, two parallel rollers are used, and several hobs are arranged on the rollers, and the prepreg passes through the middle of the two rollers. One of the rollers is the driving shaft, and the other is the driven shaft. The driving shaft actively rotates with the speed of the prepreg, and the driven s...
