Band knife structure of nap cutting machine

Abstract

The invention relates to the technical field of nap cutting machines, in particular to a band knife structure of a nap cutting machine. The structure comprises a rack, wherein a sliding frame is glidingly connected to one side of the rack, a band knife is arranged on the sliding frame, an ejection device used for ejecting the band knife is arranged on the sliding frame and comprises a propping block glidingly connected to the sliding frame and propped against the band knife and a first driving assembly arranged on the sliding frame and used for driving the propping block to move, and a bearingframe is arranged on the lower side of the sliding frame and located below the band knife. The band knife structure has the effects as follows: the first driving assembly drives the propping block tomove toward one side of the band knife, after the propping block is contacted with the band knife, the band knife can be ejected out of the sliding frame and can be collected by the bearing frame after falling, and later, an operator takes down the bearing frame and then replaces the band knife for treatment. In the dismounting process, the operator almost does not need to make contact with the band knife and can take down the band knife, the probability of cut injury of the operator is reduced, and the potential safety hazard is reduced.

Description

technical field [0001] The present invention relates to the technical field of the velvet machine, in particular to a belt knife structure of the velvet machine. Background technique [0002] The velvet cutting machine is a device used to cut the velvet layer connected in the middle of the double-layer velvet fabric. Two layers of fabric are formed, each with a uniform pile. [0003] The middle part of the double-layer fleece fabric moves on the frame and passes through the belt knife. The belt knife will cut the connecting pile layer between the fabrics on both sides. Generally, for the convenience of cutting, a driving motor will be set so that the belt knife is In a circular motion, the fabric is slit as it passes through the upper belt knife. [0004] After using for a long time, when the blade of the belt knife is worn and cannot meet the cutting requirements, the belt knife needs to be replaced, but even if the worn belt knife is still very sharp, the operator needs ...

Problems solved by technology

[0004] After using for a long time, when the blade of the belt knife is worn out and cannot meet the cutting requirements, the belt knife needs to be replaced, but even the worn belt knife is still very sharp. When disassembling, the operator needs to remove the belt knife from the transmission mechanism When removing the belt knife, the operator is easily cut, which poses a safety hazard
