Abstract
The present invention relates to a glass fibre reinforced plastic roller which is composed of a drum 1, a bearing box 2, a bearing 3, an oil sealing 4, a cover plate 5 and a shaft 6, wherein both ends of the roller are thin, the roller middle is thick, and unsaturated resin glass fibre reinforced plastic is used as raw materials which are moulded in a horizontal mode and are pressed and shaped at a time on a press machine. The shaped drum and the bearing box can be directly assembled into the glass fibre reinforced plastic roller without reprocessing. The roller has the advantages of good concentricity and proper alignment, stable operation, wear resistance without belt scratch, light weight, low noise and long service life, and price is lower than the price of a steel roller of the same specification.
Description
The present invention relates to the belt conveyer glass-reinforced plastic idler and the method field of manufacturing of nonmetallic materials.
Existing belt conveyer carrying roller is generally the steel carrying roller, and its structure and manufacture craft are: steel pipe is processed into roller on request through lathe, and steel plate strikes out the shape for hat bearing housing, and the two is connected to roll body with spot welding, refills axle, bearing, oil sealing etc. and becomes carrying roller.But there is following shortcoming and defect in the steel carrying roller:
1, the roller of steel wears no resistance, and steel disc was very sharp after especially mill leaked, and easily scratched, scratches belt, caused heavy economic losses.
Reasons such as 2, sum of errors bearing housing and the roller owing to machining welds, and be fixing have influenced the concentric co-axial degree of carrying roller, so have caused poor work stability, and noise is big, directly influences bearing life.
3, the steel carrying roller is perishable, and under high corrosive environment, the life-span is short when using in the saltern.
In order to overcome the shortcoming and defect of steel carrying roller, it is primary raw material that purpose of the present invention adopts the unsaturated resin glass fibre reinforced plastics (SMC) with the high strength high-mechanical property, adopts horizontal mold pressing one-step moulding method to produce glass-reinforced plastic idler and replaces the steel carrying roller.
The structure of glass-reinforced plastic idler of the present invention as shown in Figure 1.This carrying roller is made up of roller 1, bearing housing 2, bearing 3, oil sealing 4, cover plate 5 and 6 on axle, and wherein roller 1 is the thin thick middle in two ends, intermediate portion length l
1And the ratio of roller length overall l is between 1: 3～1: 6; Roller end overall diameter d
1With l in the middle of the roller
1The interior diameter d of section
2Ratio, i.e. d
1: d
2=(1.5～2.0): 1, the thickness of roller 1 end e should be between 10～20mm.It is raw material that carrying roller of the present invention adopts unsaturated resin glass fibre reinforced plastics (hereinafter to be referred as SMC), and adopts disposable horizontal compression-moulding methods manufacturing.The technology of compression molding is according to accompanying drawing 1 structure, according to the carrying roller specifications design and produce the mold pressing horizontal die, SMC is pressed into sheet, be placed in the mould on the forcing press, energising is heated and is kept a period of time, SMC is pressed into roller 1 and bearing housing 2 respectively, after the outage it is taken out from mould, roller after the moulding and bearing housing do not need any processing, then bearing housing 2 is embedded in the roller 1, be respectively charged into bearing 3, axle 6, oil sealing 4 and cover plate 5 again, finished the manufacturing process of carrying roller; Molding temperature is controlled at 100～150 ℃, and molding pressure is controlled at 15～25MPa, and the mold pressing heat-insulation pressure keeping time is 10～17 minutes.
Glass-reinforced plastic idler of the present invention has following advantage and effect:
1, wearability is good, and does not scratch belt.SMC is the pulverize powder after rubbing, and is less to the travelling belt infringement.
2, because the concentric co-axial degree height of carrying roller of the present invention, good dynamic balance, stable, noise is little.
3, carrying roller of the present invention is in light weight.Glass-reinforced plastic idler only is 50～60% of a same specification steel carrying roller weight.Since in light weight, be easy to roll change, labor strength is little, and the gross weight of belt feeder also reduces thereupon.
4, price is than steel carrying roller low 10%.Improve service life more than 1 times.
Be embodiments of the invention below.SMC is pressed into thin slice, it is placed in respectively in the roller and bearing housing mould on the forcing press, energising is warmed to 125 ℃, and is incubated 10 minutes, and pressure is controlled at 20MPa.After the outage, take out roller and bearing housing, the length overall l of roller is 530mm, middle long l
1Be 150mm, roller end diameter d
1Be 159mm, middle l
1The diameter d of part
2Be 99mm, the thickness of cylinder end e is 12mm, then bearing housing is packed in the roller, bearing, oil sealing, cover plate and axle are installed again, and this is a collection of makes 10 altogether, and this batch glass-reinforced plastic idler is on probation on the heavy belt of Anshan iron and steel plant Dagushan Iron Ore Mine, used in nearly ten months, do not take place that belt scratches wearing and tearing, noise is significantly less than the steel carrying roller, surpass the steel carrying roller service life, welcome by operating personnel.
