Continuous cutting process for cylinders

Abstract

The invention discloses a continuous cutting process for cylinders. The process comprises the steps of unwinding, pre-forming, sewing, saving cloth, measuring range, cutting and conveying, wherein an unwinding frame is a passive dual-station; a compression roller is automatically lifted after roll materials are used up; a pre-rolling device is arranged in front of a sewn cylinder; a groove facilitating winding and guiding of the cylinder materials is arranged at the rubber covered roll which is spliced, sewn and contacted with the cylinder materials; a cloth storage carriage of a cloth storage machine is combined with a linear bearing by adopting two optical axes, and the speed of a range roller is automatically adjusted according to the cloth storage capacity; power of the range roller comes from a servo speed-reducing motor, and is fed back to a programmable logic controller (PLC) by an encoder to measure length; a bidirectional cutting and pressing mechanism is adopted, a high-speed circular cutter can cut bag materials back and forward without resetting; and an independent variable-frequency speed-reducing motor is adopted as a transmission belt, is linked with a range servo speed-reducing motor by the PLC, and is automatically matched with the speed of the last step so as to complete continuous cutting of cylinder. The continuous cylinder cutting process adopts bidirectional cut, and has high work efficiency, safety and reliability.

Description

technical field [0001] The invention relates to a production process for tube making and cutting, in particular to a continuous tube cutting and cutting process. Background technique [0002] The working purpose of the continuous sewing cutting machine is to cut and count the mats made of sewing tubular materials, such as polyester, polypropylene, PPS, PTFE and other fibers, according to different specified length requirements. The disadvantages of the existing continuous tube cutting process are: 1. There is no unwinder with automatic tension control, resulting in uneven bag making line speed. 2. When the roll material is used up, the pressure roller cannot be lifted up automatically. During production, the folded edge of the roll material is often wound around the roll, causing accidents. 3. The cutting process is one-way, and the round knife must be cut from top to bottom. Therefore, the cutter motor needs to be reset every time after cutting, and the efficiency is low. ...

AI Technical Summary

Problems solved by technology

The disadvantages of the existing continuous tube cutting process are: 1. There is no unwinder with automatic tension control, resulting in uneven bag making line speed

2. When the coil material is used up, the pressure roller cannot be lifted automatically, and the phenomenon of coil material folding and winding around the roller often occurs during production, causing accidents

3. The cutting process is one-way, and the rotation of the round knife must be cut from top to bottom, so the cutter motor needs to be reset every time after cutting, and the efficiency is low

4. A variable frequency deceleration motor controls the bag feeding roller and conveyor belt, and the transmission speed cannot be adjusted

5. Use a group of cylinders to push the connecting rod or a combination of rack and pinion, which takes up a lot of space and has the potential of hurting people
