Braking device with transparent paper brake disc of cigarette packing machine

Abstract

The invention discloses a braking device with a transparent paper brake disc of a cigarette packing machine. The braking device comprises a bracket, a brake rack, the brake disc coaxially and fixedly connected with a transparent paper roll, and a brake band wound on the brake disc, wherein one end of the brake band is fixedly connected to the brake rack, and the other end of the brake band is fixedly connected to the bracket; the middle part of the bracket is rotatably arranged on a rotating shaft; one end of the bracket is also connected with a spring; the other end of the spring is connected with an adjusting bolt; and the connection points of the brake band and the spring on the bracket are respectively positioned on two sides of the rotating shaft. According to the invention, an original brake block is replaced by the soft brake band, so that a large package angle is realized, the frictional area is increased, the damping force for the swinging of the bracket is more uniform, and the dynamic stable swinging of a swinging arm is realized; and the braking device disclosed by the invention can be used for providing brake resistance for the spreading and transportation of transparent paper and the quality stability of related products, so that the equipment outage rate is reduced, the transparent paper consumption is reduced and the product cost is lowered.

Description

technical field [0001] The invention relates to cigarette machinery, in particular to a brake device for a transparent paper brake disc of a cigarette packaging machine. Background technique [0002] In the cigarette packaging machine, the transparent paper roll is coaxially fixedly connected to the brake disc, and the friction force is applied to the brake disc through the friction plate to ensure that the transparent paper rolls out at a relatively stable speed. During the conveying process, the transparent paper will generate tension on the swing arm, causing the swing arm to swing, and the bearing on the swing arm drives the adjustment plate to swing, and the brake frame, the friction plate and the adjustment plate are fixedly connected together, so that the friction plate and the brake disc As the gap becomes larger, the friction force decreases, and the speed of the transparent paper roll increases; as the speed of the transparent paper increases, the pulling force of ...

AI Technical Summary

Problems solved by technology

Due to its structural limitations, the transparent paper roll holder, adjustment and brake need to be disassembled during replacement, which is time-consuming and laborious to replace

[0006] (3) Uneven wear affects the braking effect of the transparent paper roll, making the speed of the transparent paper roll unstable after unrolling, causing the packaging and sealing positions of the transparent paper to remain relatively fixed, which has a negative impact on the packaging quality of the transparent paper. certain influence
