Automatic compression joint material breaking and material changing mechanism for hygienic product coiled material and material breakage method

Abstract

The invention relates to an automatic compression joint material breaking and material changing mechanism for a hygienic product coiled material. The mechanism comprises a left unwinding mechanism, a right unwinding mechanism, a compression joint material breakage mechanism, a tension control mechanism, a deviation correcting mechanism and a programmable logic controller (PLC); positive rotation or negative rotation of left and right motor shafts is controlled by the PLC; the compression joint surfaces of compression joint plates in a compression assembly are opposite, and the compression joint plates are connected with pistons of two compression joint cylinders respectively; two sets of cutting assemblies have the same structure and are distributed opposite, transition wheels in the cutting assemblies are connected with the upper parts of an inner swing arm and an outer swing arm through transition wheel axles, and the lower ends of the inner swing arm and the outer swing arm are connected with a main shaft through a bearing respectively and can be outwards turned, opened and reset; two ends of a serrated cutter are positioned on the shaft seats of the inner swing arm and the outer swing arm and positioned below the transition wheels; one end of a cutting cylinder is sleeved on a positioning rod, and the other end of the cutting cylinder is hinged with a cutter shaft through a connector and drives the serrated cutter to extend or reset; a compression plate is positioned above the transition wheels and connected with the piston of a compression cylinder through a top plate; and the compression cylinder drives the compression plate to extend or reset.

Description

technical field [0001] The invention relates to a mechanism capable of effectively and reliably bonding the running sanitary product roll material to the spare sanitary product roll material, and automatically crimping the sanitary product roll material of any thickness and fastness. , which belongs to the field of automatic refueling equipment manufacturing of raw materials for sanitary products. Background technique [0002] CN101973143A, the name "automatic material changing device and pre-compression air circuit", it includes a cylinder, the piston rod of the cylinder is connected to a slider, the two sliders are symmetrical to each other, and a cutting mechanism and a material receiving mechanism are installed on the slider. The cutting mechanism is composed of a cutting knife, a buffer device and a bottom knife, the cutting knife is installed above the slider and is symmetrical left and right, and the bottom knife is fixedly installed on the overall production equipmen...

AI Technical Summary

Problems solved by technology

[0006] The disadvantages of the above-mentioned background technology: one is that the cutting knife in the cutting mechanism is restricted by its structure, so it is easy to cut continuously, and its cutting knife needs to be replaced frequently; the other is that it is restricted by the splicing mechanism. The splicing reliability of materials is poor, and it is easy to cause bonding and falling off; the third is that it is not easy to cut off the raw materials with thick thickness and good fastness
