Filter stick forming machine

Abstract

The invention relates to a filter stick forming machine which comprises a speed sensor and a glue supply device, wherein the speed sensor is used for detecting conveying speed of forming paper for cigarettes, the glue supply device comprises a first glue supply branch circuit and a second glue supply branch circuit which are arranged in parallel, the first glue supply branch circuit is provided with a switching valve in series, the second glue supply branch circuit is provided with a glue supply pump in series, the glue supply device further comprises a controller and a motor, the controller is connected with a speed sensor in a sampling way, and connected with a motor in a controlling manner, and the motor is in mechanical driving connection with the glue supply pump. According to the filter stick forming machine, firstly, the controller controls the rotation speed of the glue supply pump correspondingly according to the collected conveying speed of the forming paper, and then controls the flow ratio of the glue, so that the glue can be conveyed out practically according to requirements, the glue accumulation phenomenon caused by overlarge flow ratio of the glue is prevented, and the problem of low quality of filter sticks caused by too low flow ratio of the glue is also solved; in addition, when the glue supply pump or the motor has faults, the first glue supply branch circuit can be used for carrying out glue conveying operation continuously, so that great influences caused by machine halt to the production is avoided.

Description

technical field [0001] The invention relates to a filter rod forming machine. Background technique [0002] The production of cigarette filter rods is to use tow as a filler, spray a certain proportion of plasticizer, and then wrap it with filter rod forming paper to obtain a filter rod. In the filter rod production process, a filter rod forming machine is required. The filter rod forming machine includes a tow conveying device, a forming paper conveying device and a forming paper gluing device. The forming paper needs to be coated with glue on its surface before wrapping the tow. Liquid, forming paper gluing device is exactly in order to realize the equipment that glue is coated on forming paper, and the glue in the existing forming paper gluing device utilizes self gravity to flow out on the forming paper. The problem with the existing forming paper gluing device is that the glue liquid uses gravity to flow by itself, resulting in a fixed flow rate of the glue liquid. Whe...
