Abstract
The present invention provides a new method for connecting the joints of a conveyer belt. In the method, a bicomponent polyurethane elastomer solidified at room temperature is used as joint binding and filling material, and operating requirements can be achieved by heating, pressurizing and solidifying a joint body at a temperature of 60 to 70 DEG C and a pressure of 0.01 to 1.0Mpa for 15 minutes. The present invention provides the concrete forms of three heating and pressurizing devices. Compared with a traditional rubber vulcanizating method, the method has the advantages of low cost, light weight, short joint connecting time, simple technology and approximate joint quality, and is suitable for various joints of conveyer rubber belts.
Description
Technical field the present invention relates to joint (interface) technology of the conveyer belt on the rubber conveyer.
The transportation of background technology adhesive tape is widely used in the industry-by-industry of national economy, as thermoelectricity, metallurgy, mine, building materials, chemical industry, storing, harbour handling etc. as the principal mode that transports continuously.When installing and change conveyor belt, must be connected into closed to the adhesive tape of lopping at the scene.Here it is conveyer belt joint.Require joint and adhesive tape other parts uniform thickness, tensile strength reaches instructions for use, and the joint life-span is long.Owing to normally finish at the scene, also require the operating time short, equipment is light, and labour intensity is low, and technology is simple.
The conveyer belt jointing method that has been widely used at present has the mechanical type connection, the bonding and rubber heat curing system based on the normal temperature of neoprene adhesive.The advantage that mechanical type connects is that the activity duration is short, but strength of joint is low, has only the 30-40% of tape tensile strength usually, and the life-span is short.The rubber heat curing system has the strength of joint height, the advantage that the life-span is long, but need sulfurator, technical matters requirement height, the joint of special use, heaviness consuming time many.Normal temperature is gluing to be connect between between the two.For the steel wire rope rubber strip, can only use heat curing system at present.
The invention provides a kind of new conveyer belt jointing method, with the strength of joint height of the method, the joint time is short, equipment manufacturing cost is low, in light weight, labor strength is little.Be applicable to conveyer belt, steel-cord conveyor belt and other special adhesive tape of various band casing plies.
Summary of the invention feature of the present invention comprises: 1. use the bonding and packing material of bi-component normal-temperature solidification polyurethane elastomer as tape splice; 2. butt joint partly applies certain temperature, quickens its solidification process; 3. butt joint partly applies certain pressure, makes it closely knit and smooth.
Normal-temperature solidification polyurethane elastomer is a bi-component.Making the glue body by polyethers or the pure and mild polyisocyanates of polyester polyols through the reaction under uniform temperature and time is a component, and forming curing agent with vulcanizer, composite catalyst is another component.The two can at room temperature react curing after mixing stirring.Colloid after the curing, tensile strength is greater than 20Mpa; Hardness is between Shao A65-90; Elongation rate of tensile failure is greater than 300%.
By research, find solidification temperature having the greatest impact to hardening time to bi-component normal-temperature solidification polyurethane elastomer curing environment and process.When temperature during, only need 15 minutes hardening time at 60-70 ℃.It is decided to be the best curing temperature of fittings body at this.
The thickness of conveyor belt is below 20mm; The width of blank area is the width (being generally 600mm-2000mm) of adhesive tape, and length is then decided with load, but is generally less than 1200mm.Heating apparatus is two parts up and down, and for flat planar, length and width equal or be slightly larger than the length and width of blank area.Can use methods such as electric boiling plate, Electric radiant Heating Film, medium heating.Corresponding temperature control equipment is arranged, and its temperature-control range is at 40-80 ℃.
Butt joint part applied pressure, its scope is between 0.01-1.0Mpa.For reaching the purpose of pressurization, once workbench and top board are arranged.Both are by mechanical locking device, and butt joint is partly exerted pressure.In order to guarantee the even of each point pressure of blank area, between top board and following workbench, add the water of a sealing or the mould device of oil or other medium in case of necessity.
Following workbench is formed with engineering materials such as iron and steel, aluminium, timber, plastics.Have enough strength and stiffness.The length and width of working face (upper surface) is big than the tape splice part.Support should be arranged at the bottom, on the support fixture should be arranged, and workbench can be fixed on the longitudinal carrier of rubber conveyer.The total height of workbench should satisfy: after it was fixing, working face was higher than the upper limb of the middle holder of belt rod.
Heater, mould device and workbench, top board can independently exist up and down, can also make up.
Beneficial effect has the mechanical property approximate with rubber with bi-component normal-temperature solidification polyurethane elastomer sticky object and the filler as fittings body after it solidifies, so the intensity of joint is approximate when adopting heat curing system.Solidification temperature only needs 15 minutes hardening time in the time of 60-70 ℃.This temperature is decided to be the joint solidification temperature, and the solidification process of joint can be finished (comprise and heating up and cooling) in 30-40 minute.This temperature reduces more than one times than the curing temperature (140 ℃) of rubber, helps reducing heating required power and heating and cooling time.
Butt joint body applied pressure only needs about 0.01-1.0Mpa.This pressure is also much smaller than the sulfide stress (1.4Mpa) of rubber, and also not high at the coherence request of each point to pressure, helps the simplification of pressure apparatus.
Compare with existing vulcanizing equipment, the weight of this device can reduce more than 2/3, and cost can reduce more than 4/5, and the joint required time then can reduce over half.
Description of drawings Fig. 1 is a kind of pressue device of heating.
Fig. 2 is the another kind pressue device of heating.
Fig. 3 is the pressue device of heating that has the mould device.
Fig. 4 is the rope belt fittings body.
The specific embodiment is in the pressue device of heating shown in Figure 1, and support 101 is arranged at following workbench 10 bottoms, and fixture 102 is arranged on the support, and workbench can be fixed on the longitudinal carrier of rubber conveyer; The bolt that some is arranged all around.Be followed successively by down heating plate 11, tape splice part 12 above it, go up heating plate 13 and top board 14.Around the top board 14 with following workbench bolt corresponding portion grooved hole, bolt can slip in it, finishes butt joint and partly pressurize under nut fastening.Heating plate is with same temperature controller 15 up and down.
