Abstract

The utility model discloses a device for manufacturing flame-retarded transport belt which is used for conveying minerals on mine exploitation face, comprising a braiding baseband bracket, a drying baker, an impregnating smearing apparatus, a gelator, a plasticator, a cooler, a fixing scoring roller, a driving motor and a finished product bracket. The impregnating smearing apparatus comprises a metal slot which is filled with polyvinyl chloride resin and various additive pastes and a pair of smearing roller whose spacing can be adjusted. A core belt is semi-plasticizd by the gelator after the braiding baseband is impregnated and smeared. Upper glue pastes are also smeared and completely plasticizd in the plasticator. The gelator and the plasticator are respectively provided with far infrared heaters to control heating temperature. Compared with common hot press platen method manufacturing devices and squeezing and smearing method manufacturing devices, the device has the advantages of less investment, simple operation, strong adhesive force of the surface glue of the finished product conveying belt, etc.

Description

Device for manufacturing flame-retarded transport belt

Fire retarding conveying band is the conveyer belt that is composited at the belt carcass surface applying one aspect glue with certain intensity and bearing property.Be used for growing apart from conveying mineral on the mining face, because the condition of work restriction, conveyer belt also should have wearability and anti-flammability more.The production method of present domestic fire retarding conveying band has two kinds: (one), the hot pressing flat band method, promptly will weave good whole core earlier, in the polyvinyl resin paste material that configures through agitation grinding, flood, heating plasticizing becomes the whole belt core that solidifies, face glue is the thin slice that rolls into 1～1.5mm after plasticating with Corvic and various additive on calender, last belt carcass and last, following sticker lumps together, put into vulcanizing press heating pressurization, a section applying forms, this discontinuous production method efficient is not high, and the adhesive force of big glue of equipment investment and belt carcass is relatively poor.(2), squeeze embrocation, in advance with the Corvic plasticizer, fire retardant, antistatic agent, various raw and auxiliary materials are through mediating, granulating working procedure is made the garden cylindrical particle and is made face glue usefulness fully, finished product production is worked continuously on a streamline, the whole core of the chemical fibre that promptly weaves dries by the fire the part of anhydrating through super-dry, enter to be full of in the pasty slurry groove that Corvic and various auxiliary agent make and flood, plastify fully by the plasticizing machine that far-infrared heating tube is housed then, after also uncooled belt carcass comes out, respectively there is a plastic extruder on the two sides, preprepared unit cylindrical particle material enters extruder, under electrical heating and mechanical presses effect, become the melt and dissolved pasty state of plasticizing, the outlet of extruder is the width mould consistent with belt body, the thickener that dissolves of plasticizing is wiped belt carcass two surfaces that hang in advancing through mold formation ground, and calendering cooling forming at last pressurizes.This method is compared with the hot pressing flat band method has the production efficiency height, the reasonable advantage of the adhesive force of face glue on belt carcass, but the big power consumption of equipment investment is big, especially outage suddenly in production process, and thickener melt and dissolved in the extruder will solidify.Stop up mould and cause product rejection.External more advanced inhibiting tape production technology is to be coated with to scrape working system, because many aspects adopt computer control, equipment investment is bigger.

The design's purpose is after the pluses and minuses of analyzing hot pressing flat band method and crowded embrocation, with reference to external advanced technologies and production equipment, in conjunction with domestic actual conditions, concentrate to solve problems such as continuous production face glue and belt carcass adhesive force, and a kind of small investment that proposes and the fire retarding conveying band process units of practicality.

This device mainly comprises following a few part.Base band support: by roller of two A-frame supportings, the base band that rolling is woven into chemical fibre on the roller.Drying baker: similar with common drying plant.In establish resistance type heater or far-infrared heater, when base band can be dried by the fire except that moisture content by drying baker.Dipping is coated with curette: dipping tank 18 is metal rectangular grooves, be full of the thickener that emulsion pvc resin and various assistant agent are made in the groove, base band is coated with by dipping tank and hangs up thickener and scrape roller by a pair of being coated with, it is adjustable being coated with the distance of scraping roller and base band two sides, thickness and uniformity in order to the thickener coating of control base band two sides, its concrete structure Fig. 2 shows, two axles 19 are arranged in the groove of bearing 21,22 1 of adjusting screw(rod)s are that screw rod one end has handwheel, one rectangle fixed block is arranged between screw rod and the handwheel, the fixed block of adjusting screw(rod) embeds in the groove of bearing 4, the screw rod of other end is threaded the two ends of two axles 19 to 4 adjusting screw(rod)s should be arranged with axle 19 radial hole, rotate the then level interval of regulating shaft in the bearing groove of handwheel, be coated with scrape the roller 20 usefulness bearings be fitted in the axle 19 on, can sway, axle 19 can also replace by being coated with scraper plate, the shape that is coated with scraper plate can be made the rectangular or edge of a knife shape of three rhombohedreon rectangles, and last gland 23 is pressed in the fixed block of adjusting screw(rod) in the bearing groove.Gelator and plasticiser: be welded into the rectangle siphunculus with metallic plate, some far-infrared heaters are set in the pipe.When being coated with, base band hangs up thickener when slowly passing through siphunculus, the control heating-up temperature, make belt carcass half plasticizing in gelator, plasticiser then makes the belt carcass of half plasticizing be coated with the plasticizing fully later on of shaving adhesive paste material, therefore the control heating-up temperature of plasticiser is higher than gelator, and the length of siphunculus was determined by the time of passing through speed and thickener plasticizing needs of belt carcass.Cooler: profile is identical with gelator.In heater is not set, the band of moulding that comes out in gelator or the plasticiser is forced to or naturally cools to normal temperature by cooler rectangle siphunculus.Typing scoring roller: be that figuratum rigid roller is scribed on a pair of surface, mould band and compress by rigid roller, the rolling finished product band that is shaped as from the centre.To the finished product belt supporting frame, work continuously by whole production line the rolling of finished product band for Motor Drive rolling live roll.

This process units, the thickener that adopts emulsion pvc resin and various auxiliary agent to prepare floods to be coated with to the braiding base band to be scraped. Carry out in the environment that is configured in vacuum outgas of thickener being half plastifying state after the heating of base band dipping. Be coated with to scrape with belt carcass through twice glue again and plastify fully, so face glue and belt carcass one integrated mass, compare with crowded embrocation, flat band method production line and have small investment, technology is simple, easy to operate, the advantages such as face glue strong adhesion.
