Description

Expansion device for strip uncoiling production Technical Field The utility model relates to the field of strip uncoiling production, in particular to a telescopic device for uncoiling production of a strip, which is mainly used for guiding the strip to smoothly enter a slitting machine for slitting operation. Background In the nonferrous metal processing industry, strip uncoiling production is a key starting link of longitudinal shearing processing. With the vigorous development of the industry, the market has put more stringent demands on the precision, production efficiency and product quality of strip processing. In the current production process, the expansion device bears the core task of guiding the strip when the strip is uncoiled, and the performance quality of the expansion device is directly related to smooth production. However, the conventional telescopic device has problems in that, on one hand, the telescopic device is easy to work and is blocked during long-term use due to limitations of structural design and material selection. For example, the precision of the connecting parts of some telescopic guide plates is not high, and in frequent telescopic actions, dislocation and clamping stagnation are easy to occur, so that the telescopic guide plates cannot be smoothly stretched and retracted. This not only prolongs the unwinding time, but also may cause deviations in the position of the strip at the initial stage of unwinding, affecting the accuracy of the subsequent cuts. On the other hand, the friction force between the telescopic guide plate and the belt material and between the moving parts of the telescopic guide plate and the belt material is too large, because the traditional telescopic device is mainly made of common materials, has large surface roughness, and generates large friction resistance when contacting with the belt material and moving relatively to the belt material. The excessive friction force can not only lead the telescopic guide plate to operate unsmoothly, but also lead the material head and the material tail of the strip to be scratched. These scratches reduce the surface quality of the strip, and for some nonferrous metal products with extremely high surface quality requirements, such as high-precision copper strips, aluminum strips and the like, the presence of the scratches may lead to direct scrapping of the product, which seriously affects the product quality and the economic benefits of enterprises. In addition, with the continuous expansion of the production scale of the large slitter and the improvement of the production speed, the traditional telescopic device cannot meet the increasing production demands. The method has the characteristics of poor stability and high failure rate, so that frequent shutdown maintenance is required in the production process, the production efficiency is further reduced, and the production cost is increased. For the above reasons, it is an urgent necessity to develop a new, efficient and stable telescopic device. Disclosure of utility model In order to solve the defects in the prior art, the utility model provides a telescopic device for strip uncoiling production, which aims to solve the problems that the traditional telescopic guide plate device is blocked in work, large in friction force and unsmooth in operation, so that the production efficiency and the product quality are affected. In order to achieve the above purpose, the utility model adopts the following specific scheme: The telescopic device for the strip uncoiling production is arranged on one side of the uncoiler and comprises a guide roller and two fixing plates arranged at two ends of the guide roller, wherein the extending direction of the fixing plates is perpendicular to the extending direction of the guide roller, a telescopic assembly is clamped between the two fixing plates, the bottoms of the two fixing plates are connected with a supporting frame, an oil cylinder is arranged on the supporting frame and can drive the telescopic assembly to reciprocate and stretch along the extending direction of the fixing plates, and then the strip is transported to the guide roller from one end of the telescopic assembly and is fed into a slitting machine for slitting by the guide roller; The upper and lower surfaces of two fixed plates are all equipped with the helping slide, helping slide and flexible subassembly contact for reduce the frictional force when flexible subassembly moves. Further, grooves matched with the fixing plates are formed in the two ends of the telescopic assembly. Further, the telescopic component comprises a telescopic guide plate which is arranged on the two fixed plates, and a sliding plate which is arranged below the fixed plates and is connected with the telescopic guide plate through a guide bolt, and a groove is formed between the telescopic guide plate and the sliding plate. Further, a positioning sleeve is sleeved on the guide bolt to ensur
