Description

Technical Field

[0001] The utility model relates to the technical field of composite ceramics, in particular to a dovetail embedded ceramic composite roller. Background Art

[0002] Traditional rubber-coated rollers use a hot vulcanization process to wrap rubber around the roller, which has defects such as poor wear resistance, easy slippage, and short life. Compared with traditional rubber-coated rollers, ceramic rubber-coated rollers have improved wear resistance and extended life. They have certain advantages such as anti-skid, anti-deviation, and no material accumulation on the surface. They can be used to transport wet and sticky materials under harsh conditions with high water content.

[0003] At present, the existing ceramic rubber-coated pulleys are mostly composed of three structures: the pulley base, the rubber layer, and the ceramic sheet. Since the ceramic sheet is in direct contact with the conveyor belt, its quality directly affects the overall service life of the ceramic rubber-coated pulley. The existing ceramic sheets are mostly square or tile structures, which are inconvenient to maintain, rubber aging, poor anti-skid performance, and embedded in the rubber. There are also problems such as low friction and easy falling off. Utility Model Content

[0004] In view of this, the purpose of the utility model is to propose a dovetail embedded ceramic composite roller to solve the problems of inconvenient maintenance, rubber aging, poor anti-slip performance of ceramic sheets in existing ceramic rubber-coated rollers, and low friction and easy falling off when embedded in rubber.

[0005] Based on the above-mentioned purpose, the utility model provides a dovetail embedded ceramic composite roller, which is applied to a belt conveyor, including a roller body, connecting shafts are provided at both ends of the roller body, and the outer surface of the roller body is provided with a plurality of evenly distributed dovetail grooves, and the interior of each dovetail groove is adapted to be embedded with a dovetail ceramic sheet, and each dovetail ceramic sheet is firmly bonded to the dovetail groove, and the outer surface of each dovetail ceramic sheet is higher than the outer surface of the roller body, and the outer surface of each dovetail ceramic sheet is fixed with a plurality of evenly distributed conical protrusions, and all the dovetail ceramic sheets are distributed in an array on the outer surface of the roller body to form a variety of striped patterns.

[0006] Preferably, the width of the dovetail groove is 10-15 mm.

[0007] Preferably, the thickness of the dovetail-shaped ceramic sheet is 4-10 mm.

[0008] Preferably, the conical protrusion is 0.5-1.5 mm higher than the outer surface of the dovetail-shaped ceramic sheet.

[0009] Preferably, the dovetail-shaped ceramic sheet is made of one of 95 alumina ceramic, ZTA ceramic or silicon carbide ceramic.

[0010] Preferably, the stripe pattern includes one of a stripe, a herringbone and a prism.

[0011] The beneficial effects of the utility model are as follows: the dovetail-shaped ceramic piece is embedded in the dovetail-shaped groove on the outer surface of the drum and firmly bonded, so that the ceramic is not easy to fall off; the upper surface of the dovetail-shaped ceramic piece is higher than the outer surface of the drum, and a conical protrusion is provided to contact the belt of the belt conveyor, which improves the wear resistance and anti-skid performance of the drum and extends the service life of the drum; the array of dovetail-shaped ceramic pieces is composed of one of strips, herringbone and diamond, which improves the anti-deviation performance of the belt conveyor; since rubber is not used, there is no rubber aging, and the problem of sharp materials damaging the rubber is avoided. The utility model not only has high wear resistance, long service life, anti-skid and anti-deviation, but also is very convenient to use and maintain, and has great application value.
