Embodiment Construction

[0009] Firstly, the raw materials are screened and weighed. They are mixed with unsaturated polyester resin and aluminum hydroxide at room temperature for ten minutes, and then mixed with steel fiber, glass fiber, nylon fiber, graphite, calcium carbonate, and quartz sand to form an agglomerate. , And then measure the material according to the size of the piece. The upper mold of the bulk material is at 150 degrees Celsius, and the mold is cured for five minutes (long rollers above 500 mm need to be lined with thin-walled steel pipes), and then the semi-finished parts are arranged and bonded, and assembled to the finished product After quality inspection, packaging and leaving the factory.

Abstract

The present invention discloses one kind of roller of composite polymer material and used widely in belt conveyer of mine, dock, warehouse, chemical plant, etc. The roller is produced with unsaturated polyester resin 30 wt%, steel fiber 10 wt%, glass fiber 10 wt%, nylon fiber10 wt%, graphite 10 wt%, calcium carbonate 10 wt%, aluminum hydroxide 10 wt% and quartzite 10 wt%, and through sieving, weighing, mixing, molding at 150 deg.c, finishing, assembling and inspection. The roller is durable, high in strength, light, anticorrosive and convenient in maintenance.

Description

Technical field [0001] The invention relates to an idler roller on a belt conveyor, in particular an idler roller molded from a new polymer composite material. technical background [0002] At present, steel rollers are commonly used on belt conveyors in well-known mines, wharfs, grain depots, cement plants, power plants, chemicals, saltworks, and other enterprises. Plastic rollers are used in a small amount. The biggest disadvantage of steel rollers is that they are easy to use. Corrosion, heavy weight, low friction coefficient, high noise, easy to be sold by thieves, many consumables, and plastic rollers have low strength, low friction coefficient and short service life. Summary of the invention [0003] In order to overcome the technical deficiencies of the existing steel and plastic rollers of belt conveyors such as easy corrosion, heavy weight, low friction coefficient, high noise, and low strength, the present invention provides a new polymer composite roller. The new poly...
