Description
Technical field
It relates to the plant equipment of roadway support the present invention, particularly, relates to the production line of glass fibre reinforced plastics rockbolts.
Background technology
Anchor pole is the element of colliery tunnel support, mainly there are two large defects in the anchor pole that conventional steel material is made, be that skill is corroded and lost efficacy and produced spark because coal-cutting machinery cuts anchor pole or anchor pole and the collision of other equipment, cause local gas blast and dust spontaneous combustion, there is potential safety hazard, therefore be eliminated gradually.Glass fibre reinforced plastics rockbolts has the plurality of advantages such as light weight, corrosion resistant, fire-retardant, antistatic, high strength, and glass fibre reinforced plastics rockbolts is widely used by each large colliery at present.In addition glass fibre reinforced plastics rockbolts is also widely used in subway tunnel, engineering bank protection, highway, bridge supporting, the fields such as municipal works.
Glass fibre reinforced plastics rockbolts is comprised of under the effect of curing agent many wire long fibres and resin.Its moulding is in hauling machine directed traction, separately with a flexible wire, carries out screw thread and is wrapped in heating cure and forms.Thread forming in glass fibre reinforced plastics rockbolts process and curing efficiency are determining the working (machining) efficiency of whole production line.The one start screw that current process equipment uses individual wire circulation to be wound around when thread forming, in the situation that the rotating speed of hauling speed and Wiring apparatus coordinates bad steel wire very easily to pull apart, causes and shuts down or produce waste product in production process.Speed of wrap is too fast or cross and can affect slowly thread pitch and change, the cooperation of impact and nut.
Also the heater that solidifies use after having people to glass fibre reinforced plastics rockbolts moulding improves, to enhancing productivity, as Chinese patent ZL201020188456.2 discloses the heater that a kind of glass fiber reinforced plastic anchor rod molding machine is used, by cartridge heater, heat and establish heat-insulation layer between cartridge heater and outer cover, improving heating effect.But because the heating system of current glass fibre reinforced plastics rockbolts equipment is electrical heating (far infrared), there is self unvanquishable defect:
1, before production, preheating time is long, at least 40 minutes;
2, because existing equipment is to put far-infrared heating tube in baking oven, and more than large (more than the needed electric power 40KW of whole production line) cost-per-meter 1 degree electricity of electric thermal power;
3, thermal loss is large, and due to the problem of baking oven heat insulation effect, the heat that electrical heating discharges is not absorbed completely by anchor pole, so the thermal efficiency is low, about 70% left and right;
4, in unexpected power failure, or mechanical disorder be when need to shut down, and the anchor pole in baking oven can and burnt because oven temperature can not be lowered the temperature rapidly, causes waste.
So only improve the efficiency that is heating and curing after fiberglass moulding and there is limitation by improving electric heater unit structure.
Summary of the invention
For above problem, the invention provides a kind of production line of glass fibre reinforced plastics rockbolts, this production line overall structure configuration is reasonable, working (machining) efficiency is high.
Technical scheme of the present invention is that a kind of production line of glass fibre reinforced plastics rockbolts, comprising: creel, storage glasses silvalin on it; Glue groove, deposits for the resin batching compound with glass fiber yarn; Screw thread wrapping machine, is molded into shaft-like glass fibre reinforced plastics rockbolts by the organdy that is compounded with resin batching; Heating system, is cured processing to the resin batching in glass fibre reinforced plastics rockbolts; Trailer system is that processed anchor pole goods are moved with the speed of subscribing; Cutting machine, cuts into processed glass fibre reinforced plastics rockbolts in the glass fibre reinforced plastics rockbolts goods with predetermined length; Also comprise the line machine that moves back, the anchor pole cotton rope good to wound and solidified carries out unwinding; And coil winding machine, the cotton rope that unwinding is got off carries out neatly playing dish, keeps constant-tension while being convenient to thread forming.
Wherein said screw thread wrapping machine comprises frame, drum, rotary body, automatically controlled part, and wrapping machine is carried out double end and is wound with a rotary body drive system and two drum drive systems, and two drum symmetries are contained on rotary body, and along with rotary body rotates.
Described heating system comprises microwave transmission system, micro-wave screening case, gel resin system, electric-control system, and microwave transmission system is comprised of a plurality of microwave emitters, and the microwave that microwave emitter is launched is over against goods; Gel resin system runs through the operation capable of circulation of micro-wave screening case.For example gel resin system is comprised of scrap belt and scrap belt carrying roller, and scrap belt is placed on scrap belt carrying roller, is provided with scrap belt carrying roller inside and outside micro-wave screening case, and scrap belt carrying roller drives scrap belt that the glue dropping on scrap belt is transported to outside micro-wave screening case.
The casing of described micro-wave screening case is individual layer stainless steel, which is provided with cover plate.
Described scrap belt is Teflon tap.
Described electric-control system is controlled with PLC, can preset the multiple method of operation.
The invention has the beneficial effects as follows; the wrapping machine of thread forming system adopts double end winding method; its speed of wrap is fast; but cotton rope speed can keep relative low speed; thereby while having solved single head winding, screw thread is wound around high-speed; when high-speed with cotton rope, cotton rope is easily broken, causes shutdown, waste product, affects the problem of output and yield rate.Simultaneously, after thread forming, adopt heating using microwave to solidify, the penetrability of microwave is good, warming and cooling rate is fast, easy-to-use, in the process of heating, can make goods heat from outside to inside simultaneously, thereby cause resin solidification rapidly, according to on-the-spot test, the anchor pole of diameter 18mm, after microwave hyperthermia, the curing molding speed of goods can reach 5-6 m/min.And traditional infrared heating, heat conduction is outside in, the thermal conductivity factor of resin is very low, absorb external heat and reach solidification temperature length consuming time, curing rate is very slow, thereby affects the shaping speed of goods, and the anchor pole curing molding speed of diameter 18mm is 1.2 meters-1.5 ms/min.Adopt production line of the present invention can improve the working (machining) efficiency of glass fibre reinforced plastics rockbolts, shaping speed is no less than 3000mm/min, reach as high as 5000mm/min, be the 4-5 of same kind of domestic equipment shaping speed doubly, save material cost (can reduce 10-30%), save process costs (2-5 unit/rice), automaticity height (3 people/2 production line) easy to operate; Environment-friendly type low energy consumption.In addition, microwave heating system is processed without insulation, there is no connector lug and any electro-heat equipment in casing, uses safer.
