Storage shelf structure

Abstract

The invention relates to a storage shelf structure which comprises a rack. A guide roller fixing frame is arranged on the rack and provided with multiple fixed guide roller sets. Each fixed guide roller set comprises multiple fixed guide rollers. A movable frame is arranged on the rack, moves relative to the guide roller fixing frame and is provided with multiple movable guide roller sets opposite to the fixed guide roller sets. Movable guide rollers are arranged on the movable guide roller sets. Traction devices driving the movable frame to horizontally move back and forth are arranged between the guide roller fixing frame and the movable frame. According to the storage shelf structure, a three-layer guide roller structure is adopted, the number of layers of punctured films is larger, the structure is more compact, the storage length is increased, and more materials can be stored; a double-floating-roller structure is adopted, tension change can be better buffered in the material receiving process, and the out of register influences caused by sudden change of tension in the material receiving process on printing are reduced.

Description

【Technical field】 [0001] The invention relates to equipment for a printing machine, in particular to a material storage rack structure for a printing machine. 【Background technique】 [0002] The material storage rack is an important part of the printing machine for changing rolls and docking materials. The material storage rack is used at the front end or rear end of the equipment. Specifically, the material storage rack is set at the rear end of the unwinding unit or the receiving The front-end station of the winding unit, the material storage rack is used to store a certain length of material tape. During the continuous connection process of the material tape, the material storage rack will output the material tape stored in the material storage rack, so that the subsequent lamination, bronzing , embossing, coating and other processing equipment can work without interruption. After completing the continuation of the tape, the storage rack will store a certain length of tap...

AI Technical Summary

Problems solved by technology

For occasions that require storage racks to store more tapes, only larger volume or length storage racks can be used to meet the process requirements. The cost of the storage rack is high, and the storage rack occupies a large space, resulting in waste of resources.

[0004] In addition, during the process of conveying the material belt by the material storage rack, the subsequent processing equipment of the material belt is pulled and moved, and the material belt drives the rotating shaft on the material storage rack to rotate accordingly during the process of conveying the material belt to the subsequent processing equipment, and the material belt on the material storage rack rotates accordingly. The rotating shafts are all passive rotating shafts. The material belt drives each rotating shaft on the material storage rack during the process of conveying the material belt to the subsequent processing equipment. During the process of conveying the material belt, the material storage rack has a very large frictional resistance to the material belt. The resistance is also the tension and stretching force of the storage rack on the material belt. The material belt is stretched after being subjected to tension and tension, causing the material belt to deform. Once the material belt is deformed, it will bring great trouble to the subsequent processing. , also affects the quality of subsequent processing
