Double-layer synchronous unwinding equipment

Abstract

The invention relates to the technical field of textiles, and aims to provide double-layer synchronous unwinding equipment. The double-layer synchronous unwinding equipment is simple in structure andcapable of improving unwinding synchronous precision and comprises a base, wherein a cloth roll bearing mechanism and a conveying mechanism are sequentially arranged on the base in the cloth conveyingdirection, an impurity cleaning mechanism is further arranged on the position, between the cloth roll bearing mechanism and the conveying mechanism, of the base, the cloth roll bearing mechanism comprises a pair of mounting side plates arranged on the two sides of the front end of the base, two unwinding barrels are arranged between the mounting side plates, the two unwinding barrels are each provided with a cloth roll, and the conveying mechanism comprises a pair of stand columns arranged on the two sides of the rear end of the base, two sets of clamping assemblies arranged between the upperends of the stand columns, and a clamping driving assembly used for driving the two sets of clamping assemblies to act synchronously. According to the double-layer synchronous unwinding equipment, synchronous unwinding of double-layer cloth can be effectively met, unwinding synchronism and stability are guaranteed, and the double-layer cloth unwinding equipment is simple in structure.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a double-layer synchronous unwinding device. Background technique [0002] Textile unwinding equipment is a kind of equipment widely used in the textile flat processing production process. Its function is to unwind the rolled cloth according to the standard feed speed of subsequent printing and dyeing equipment, composite equipment, bronzing equipment and other processing equipment, and then It is then transported to subsequent processing equipment for further processing. At present, the traditional unwinding equipment mainly includes an unwinding chute and an unwinding roller. The unwinding roller is generally composed of two upper and lower actively rotating nip rollers, and the unwinding chute is composed of a plurality of arc-shaped supporting rollers; The cloth roll is prevented from being in the unwinding groove and in contact with the idler roller, and is kept in a state...

AI Technical Summary

Problems solved by technology

However, this method is not only complicated in control logic, but also often needs to be equipped with several sensors to collect real-time working conditions

This not only increases the risk of circuit failure, but also requires a large investment in equipment costs

[0004] 2. During the pre-processing and storage and transportation of the cloth, there are often certain impurities on the surface, such as: cotton balls, thread ends, dust, etc. If these impurities are not removed, it will affect the subsequent gluing and hot pressing , printing and dyeing processes

This method has little effect on the unwinding of the cloth roll at low speed, but for the high-speed unwinding cloth roll, due to the lack of effective restrictions on the middle and upper parts of the cloth, the cloth roll jumps greatly, which easily affects the overall stability of the equipment.

For this reason, one idea in the prior art is to set a pressure roller above the cloth roll, and limit the cloth roll by pressing the top of the cloth roll through the pressure roller. This method can improve the stability of the cloth at first glance. However, the diameter of the cloth roll will become smaller and smaller during the continuous unwinding process, and the contact angle between it and the pressure roller or the idler roller is constantly changing, so simply limit the top of the cloth roll cannot solve the problem of the stability of the cloth roll

Further, affected by the unwinding speed of the cloth roll, the efficiency of the subsequent process of the cloth is also restricted
