Tension adjusting device of automatic paper splicing machine

Abstract

The invention discloses a tension adjusting device of an automatic paper splicing machine. The tension adjusting device comprises a rack, guide rollers, a floating roller, a position detector, a terminal controller, a proportional flow valve, a solenoid directional valve and band-type brake control air valves. The floating roller is formed by two oppositely-placed guide rails fixed to the position, between the first guide roller and the second guide roller, on the rack in the vertical direction, sliding blocks which are mounted on the guide rails and can move back and forth along the guide rails and a third guide roller with the two ends mounted on the sliding blocks of the two guide rails correspondingly. A laser distance measuring sensor serves as the position detector. Universal components in the automatic paper splicing machine are fully utilized, and the mechanical structure is optimized; the tension adjusting device is simple in structure and low in manufacturing cost; the problems that a tension adjusting device in the prior art is complex in structure and high in cost are solved; the use effect is good, and extremely short response time and extremely high work sensitivity are achieved; and the tension of paper keeps constant all the time, and tension control is accurate.

Description

technical field [0001] The invention relates to corrugated paper production equipment, in particular to a tension regulating device of an automatic splicer. Background technique [0002] Automatic paper splicing machine is widely used in corrugated paper production line. The so-called automatic paper splicing is to automatically complete the paper splicing process of two rolls of base paper under the condition of high-speed motion of the paper tape. When the used paper roll reaches the specified diameter (usually called When the old paper rolls are used up), the paper tapes of the new and old paper rolls will be automatically and accurately pasted together, and the old paper rolls will be cut off in time, and the paper tapes of the new paper rolls will be supplied in time for subsequent production and continuous use. The paper belt does not stop moving during the papering process, and can continue to supply paper for subsequent processing, ensuring continuous and normal oper...
