AI Technical Summary

Technical Problem

When the existing transmission roller structure transmits materials, due to the abnormal tangential force at the casing connection notch, the connection notch cracks or expands, thereby damaging the roller.

Method used

Using a transmission roller structure assembled in series, the fitting connection between the wheels is achieved by providing a recessed groove and protruding teeth with symmetrical inclination at the end of the main body tube, and the fitting connection is covered by a restraining member to ensure synchronous rotation and reduce the effect of tangential force.

Benefits of technology

It effectively extends the service life of the wheel, prevents the expansion and deformation of the depression grooves and protruding teeth, and enhances the structural strength of the restraining parts, and prevents the restraining parts from cracking.

Abstract

The invention relates to a material conveying device, and provides a driving roller structure assembled in series, which comprises wheels which are in direct contact with materials during working, and the wheels comprise outer contact wheels, a supporting framework and a main body pipe; the middle shaft penetrates through the main body pipe; sunken grooves with symmetrical inclination angles are uniformly formed in the end parts of the two ends of the main body pipes at intervals, the edges, close to the sunken grooves, of the end parts of the main body pipes are provided with protruding teeth which have the same protruding length and are matched with the sunken grooves, and the end parts of the plurality of main body pipes are embedded into the sunken grooves through the protruding teeth to be connected in an end-to-end embedding manner; and the restraining part is in a circular ring shape and is arranged at the embedded connection position of the concave groove and the protruding teeth in a wrapping mode. The embedded connection between the ends of the wheels is realized by arranging the concave grooves and the protruding teeth at the end parts of the main body pipe, so that the concave grooves and the protruding teeth are not easy to expand and deform, and meanwhile, the service life of the wheels can be effectively prolonged under the constraint of the constraint part.
