Cutting device for cutting waterproof coiled material from middle

Abstract

The invention relates to a cutting device for cutting a waterproof coiled material from middle. The cutting device for cutting the waterproof coiled material from the middle comprises an installation rack, a guide rod which extends leftwards and rightwards along a horizontal direction and the two ends of which are fixedly arranged on the installation rack, a transverse rod which is arranged in parallel with the guide rod and is movably arranged on the installation rack, an installation plate which is fixedly arranged in the middle of the transverse rod and is slidably erected on the guide rod, a cutter which is fixedly installed on the installation plate, connecting sleeves which sleeve the two ends of the transverse rod and can rotate around the direction of the axis of the transverse rod, and limiting rollers which respectively rotate around the direction of the axis perpendicular to the extension direction of the transverse rod and are arranged on the connecting sleeves, wherein the two limiting rollers are symmetrically arranged about the cutter, and when the waterproof coiled material is cut from the middle, the two limiting rollers respectively resist against the left and right sides of the waterproof coiled material. When the waterproof coiled material skews, the cutter can move with the waterproof coiled material, the cutter is always guaranteed to be located in the middle of the waterproof coiled material and the cutting accuracy is improved.

Description

technical field [0001] The invention relates to a cutting device for cutting a waterproof coiled material from the middle. Background technique [0002] At present, waterproof membranes (with a thickness of more than 3mm) are generally packaged in rolls and bundles. When cutting from the middle is required, under the action of the unwinding machine and the cutting device, the unwinding and cutting can be realized. [0003] However, in the process of unwinding, it is inevitable that the waterproof membrane will shake from side to side, causing the cutting track to reversely change, resulting in uneven cutting, which cannot meet the requirements of the standard size, and requires further processing, which not only causes the membrane waste, and bring great inconvenience to follow-up work. Contents of the invention [0004] In order to overcome the defects of the prior art, the object of the present invention is to provide a cutting device for cutting waterproof roll materia...
