Knife holder and cutting device

Abstract

The invention discloses a knife rest and a cutting device, and belongs to the technical field of product cutting. The knife rest comprises a knife rest body and at least two knife wheel installing parts arranged on the knife rest body, the knife rest body is provided with a rotating shaft, and the at least two knife wheel installing parts are arranged in the circumferential direction of a rotationshaft at intervals. When the knife rest and the cutting device are used, one knife wheel can be installed on each knife wheel installing part, when the knife wheels need to be replaced, the knife rest is rotated, the knife wheel to be used is switched to the needed position, the knife wheels do not need to be demounted or reinstalled, time is saved, and the production efficiency is improved; meanwhile, the knife wheel within the service life does not need to be demounted from the knife rest, when the knife wheel needs to be reused, only the knife rest needs to be rotated again to enable the knife wheel to align at a to-be-cut product for reusing, each knife wheel can be sufficiently used, and cost is saved. In addition, the knife wheels are not demounted from the knife rest, and thereforethe problem of the high reject ratio caused by reinstalling after demounting of the knife wheels can be solved.

Description

technical field [0001] The invention relates to the technical field of product cutting, in particular to a knife holder and a cutting device. Background technique [0002] In the manufacturing process of some plate products, such as glass plates or liquid crystal panels, etc., it is necessary to use a cutting device to cut them, and plate products of different thicknesses or sizes need to use different types of cutter wheels. Different types of cutter wheels have different parameters such as diameter, cutter wheel angle, and number of teeth. The current cutting device usually includes a knife holder and a cutter wheel installed on the knife holder. In actual production, when plate products of different thicknesses or sizes need to be produced on the same production line, the cutter wheel needs to be disassembled from the knife holder. Then reinstall the desired type of cutter wheel. [0003] However, frequent disassembly and assembly of the cutter wheel will reduce the uti...
