Ventilation carrier roller device of tipping paper laser perforating machine

Abstract

The invention discloses a ventilation carrier roller device of a tipping paper laser perforating machine. The ventilation carrier roller device of the tipping paper laser perforating machine comprisesa ceramic carrier roller with a shaft center through hole, a ventilation shaft with a shaft center through hole, a sealing bolt, an APBT-type threaded tee joint, two high-speed bearings, elastic retaining rings for shafts, two sealing glands, O-shaped rings and elastic retaining rings for holes; the ventilation shaft is arranged in the shaft center through hole of the ceramic carrier roller in asleeved mode; ventilation holes are formed in the ventilation shaft; the sealing bolt is arranged in one end of the ventilation shaft; the APBT-type threaded tee joint is arranged on the other end ofthe ventilation shaft; the two high-speed bearings are arranged between the inner wall of the ceramic carrier roller and the outer wall of the ventilation shaft; each elastic retaining ring for shaftsis arranged between the corresponding high-speed bearing and the ventilation shaft and can be used for fixing the high-speed bearing to be connected with and position the ventilation shaft; the two sealing glands are arranged on the two sides of the inner wall of the ceramic carrier roller and at the outer side of the high-speed bearings; each O-shaped ring is arranged between the corresponding sealing gland and the ceramic carrier roller; and the elastic retaining rings for holes are arranged on the inner wall of the ceramic carrier roller and are used for fixing the sealing glands. The ventilation carrier roller device of the tipping paper laser perforating machine has the advantages that dust adsorption on the surface of the carrier roller is effectively reduced, dust is effectively prevented from entering the inner structure of the carrier roller, the mechanical rotation stability of the carrier roller is ensured, and the service life of the machine is prolonged.

Description

technical field [0001] The invention relates to an idler device in the manufacture of auxiliary materials in the cigarette industry, in particular to a ventilation idler device for a laser punching machine for tipping paper. Background technique [0002] In the process of laser punching the tipping paper of cigarette auxiliary materials with the existing roller device, when the tipping paper tape passes through the lower roller of the laser head of the laser punching machine, the laser emitted by the laser head is on the tipping paper tape Drilling holes will generate dust at the same time. The dust will be adsorbed on the surface of the idler roller and the end faces on both sides of the idler roller, so that the dust will enter the inner hole of the idler roller and the bearing of the idler roller, which will reduce the service life of the machine and affect the roughness of the idler roller surface and the rotation speed of the idler roller. Furthermore, the friction for...

Problems solved by technology

The dust will be adsorbed on the surface of the roller and the end faces on both sides of the roller, so that the dust will enter the inner hole of the roller and the bearing of the roller, which will reduce the service life of the machine and affect the roughness of the surface of the roller and the rotation speed of the roller. Furthermore, the friction force of the tipping paper tape relative to the roller is changed during operation, which seriously affects the hole shape of the tipping paper after laser drilling and various technical indicators (air permeability and variation coefficient) of the paper tape, resulting in poor product quality. Instability of mechanical rotation
