Oil-applying and scrap-removing device for circular cutter

Abstract

The invention discloses an oil-applying and scrap-removing device for a circular cutter, comprising an oil inlet tube. A sucking pump is arranged at the oil outlet end of the oil inlet tube; the oil outlet of the oil inlet tube is inserted into a sponge; the sponge is arranged at the cutting edge of the circular cutter; a semicircular retaining plate is arranged at the clockwise lower part of the sponge; the section of the retaining plate is U-shaped; the horizontal section of the U shape is a flange covering the upper side of the cutting edge of the circular cutter and the upper end of the vertical section of the U shape is fixed at the circular cutter central shaft; the cutting edge extends into the sponge; and the sucking pump is equipped with a flow control valve. The device is economical, easy to use, simple in structure and low in manufacturing cost. The device can take good effect of protecting the cutting edge.

Description

technical field [0001] The invention relates to a circular knife oiling and dedusting device, which is a device installed on the edge of a circular knife for cutting paper tubes, used for oiling the edge and removing paper scraps on the edge, and belongs to the field of machinery. Background technique [0002] During the production and processing of paper tubes, cutting paper tubes is a common process. In order to improve the quality of the cutting surface and avoid the deformation of the paper tubes during the cutting process, the current factories usually use round knives for cutting. During the cutting process, the round knives Rotating at high speed, the paper tube rotates one circle on the rotating knife edge to complete the cutting. There will be some paper scraps on the edge of the knife, which will affect the quality of the cutting surface, make the cutting surface rough, and also have a wear effect on the edge of the knife, which will accelerate the bluntness of the...

AI Technical Summary

Problems solved by technology

The traditional method is to install an electric fan next to the device where the circular knife cuts the paper tube, and use the wind to blow away the paper scraps. However, the paper scraps are difficult to collect and scattered in the workshop, which deteriorates the working environment of the workshop. The wind also has a cooling effect on the knife edge. However, the knife edge is too dry, and it is easy to chip the teeth, causing the round knife to be scrapped.
