Description

A device for accurately adjusting the position of a tipping paper washboard

Technical field

The invention relates to the technical field of loading and unloading machines in tobacco enterprises, and in particular to a device for accurately adjusting the position of a tipping paper washboard.

Background technique

The tipping paper pick-up and loading machines used by tobacco companies, especially the YJ27 pick-up and loading machine, have tipping paper washboards located under the claw wheel and tobacco rubbing drum of the pick-up and loading machine. When the equipment is running, the cigarette rubbing drum uses negative pressure to adsorb the tipping paper and the cigarette tip stick (two cigarettes with a length of 59mm and a double long tip stick with a length of 50mm) on its surface and rotate in a clockwise direction. When the tipping paper board 1 rubs and joins the surface, the cigarette and the tip stick rotate counterclockwise under the friction of the surface of the washboard. The cigarette and the tip stick begin to combine with the tipping paper sheet coated with glue on the surface. As the cigarette is rubbed, As the drum continues to rotate clockwise, the cigarette, tip rod 7, and tipping paper 8 are combined together, and the tipping paper is attached to the surface of the cigarette and tip stick. The tipping paper rubbing process is completed. The spliced double-length cigarettes are adsorbed on the surface of the splicing drum and continue to be transported downwards. During the tipping paper rubbing and splicing process, the working principle of the tipping paper rubbing board is shown in Figure 1.

When the equipment is shut down, the washboard should be kept away from the smoke drum. When production resumes, the washboard should be close to the smoke drum. The existing adjustment device can adjust the positions of the tipping paper washboard and the smoke rubbing drum, but it cannot accurately adjust the positions of the tipping paper washing board and the smoke rubbing drum, which affects the tipping paper splicing quality of the splicing machine.
