On-line automatic photographic film storage speed setting device, system and method

Abstract

The invention discloses an on-line automatic photographic film storage speed setting device, system and method. The on-line automatic photographic film storage speed setting device comprises a photographic film winding roller set which is arranged between a front-end conveying line and a rear-end conveying line. The photographic film winding roller set comprises a floating dual pressure roller assembly and a fixed roller assembly. The floating dual pressure roller assembly comprises floating dual pressure rollers which are mounted in the front-back direction through a movable roller bracket. Vertical guide rails are mounted on the movable roller bracket in a sliding manner through a left sliding seat and a right sliding seat. The guide rails are mounted on a left vertical rack and a right vertical rack. A floating mechanism for ascending and descending the floating dual pressure rollers is arranged on the racks. The fixed roller assembly comprises a fixed roller mounted through a fixed roller bracket. The fixed roller is arranged on the ascending and descending path of the floating dual pressure rollers with the position corresponding to the position between the floating dual pressure rollers. The fixed roller bracket is provided with an ultrasonic detection assembly, wherein by detecting the heights of the floating dual pressure rollers, the ultrasonic detection assembly adjusts conveying speeds of a front-end photographic film and a rear-end photographic film so that the conveying speed of the front photographic film can be matched with the conveying speed of the rear photographic film. The on-line automatic photographic film storage speed setting device, system and method are applied to the industry of wide strong conveying belts, and automatic storage, speed setting and continuous and ceaseless conveying of the photographic films are achieved.

Description

technical field [0001] The invention relates to film production technology, in particular to a film online automatic storage speed setting device and its system and setting method. The device is mainly used in film extrusion and / or calendering production lines, and involves film storage and speed setting of conveyor belts. And other related technologies, can realize the continuous and uninterrupted conveying of the film online. Background technique [0002] The film extrusion and calendering production line must ensure continuous and uninterrupted work of the film online during the production process. According to the requirements of different coiling lengths of the film, it is necessary to stop conveying and cut the film on the cutting conveyor belt, while the conveyor belt production line at the front end of the cutting conveyor belt is The work cannot be stopped. Therefore, a storage device capable of storing a certain amount of film should be provided between the cutting...

AI Technical Summary

Problems solved by technology

[0004] 1. The storage pit of the conventional storage device is not enough for the film storage capacity, and cannot meet the time required for wide-width film cutting, and cannot meet the requirements of wide-width film extrusion production line for winding and cutting.

[0005] 2. The conventional speed setting device is a swing arm structure. Due to the limitation of the length of the swing arm, it cannot effectively contact the film during storage, and the film will be deformed during transportation, making the film transportation unstable and poor in reliability.

[0006] Therefore, the conventional storage device and speed setting device mode cannot meet the continuous and uninterrupted production requirements of the wide-width film extrusion and calendering production line
