Description

Automatic production line for conveying rollers of drying machine

Technical Field

The utility model belongs to the technical field of mechatronic device, concretely relates to automatic production line for desiccator conveying roller. The automatic part feeding and positioning in the whole manufacturing process of the conveying roller of the drying machine, the automatic assembly of the conveying roller parts, the automatic feeding and discharging of different stations, the automatic welding between the parts after the assembly of the conveying roller and the automatic straightening of the welded conveying roller are realized, and the whole manufacturing process of the conveying roller is automatically completed.

Background

The dryer is a mechanical device for reducing moisture of materials by using heat energy and is used for drying objects. The purpose of drying is for material use or further processing requirements. For example, the wood can be dried before making wood mould and woodware to prevent the product from deforming, and the ceramic blank can be dried before calcining to prevent the cracking of the finished product. In addition, the dried material is convenient to transport and store, for example, the harvested grains can be prevented from mildewing after being dried to be below a certain humidity. Since natural drying is far from meeting the requirement of production development, dryers are increasingly widely used in recent years, and a large number of conveying rollers are required to be used in the dryers to convey materials. Therefore, the improvement of the automation degree of the conveying roller production line is of great significance to the improvement of the yield of the dryer.

In order to reduce cost and weight, conveying rollers are generally assembled by adopting hollow pipes and two end spindle heads at present. However, the existing shaft head pressing process, the welding process of the shaft head and the steel pipe and the straightening process are all completed manually, and need to be completed on a plurality of devices, so that the automation degree is extremely low, and more labor force is needed. Particularly, in the aspect of alignment, most of the current enterprise production is completed manually, alignment is performed by means of experience of workers, and therefore the alignment device is low in efficiency, high in labor intensity, low in alignment precision and unstable in quality, and becomes a bottleneck problem of improving product quality and production efficiency of enterprises at present, and needs to be solved urgently. The conveying roller is used as an important basic link in a dryer production line, and the quality of the conveying roller has a crucial influence on the quality of a final product. For example, the cylindricity of a roller is an important indicator of the performance of the roller, and the quality of the performance directly influences the stability and reliability of goods conveying. If the cylindricity is too large, the jolt of the conveyed object can be caused, the normal conveying direction is deviated, the accuracy of the conveying action is influenced, the noise becomes large, and even the damage of part of the conveyed object and the service life of the whole conveying equipment are shortened.

The utility model relates to a conveying roller automatic production line equipment can realize the continuous automatic production of conveying roller to solve present conveying roller production efficiency low, intensity of labour is big, and the precision is low, the problem that the recruitment number is many.
