Description
Technical field
The invention belongs to the technical field of rubber conveyor belt product, be specifically related to a kind of straight conveyor belt finger-model connector and preparation method thereof.
Background technology
The enterprises such as current increasing harbour, coal, iron and steel, cement, for enhancing productivity, increase the use to load-transfer device, and meanwhile client requires also more and more higher to the strength specification of load-transfer device.Common plain weave canvas bends up and down due to warp, and when vertical equity is stressed, a part of application force is broken down into vertical direction and goes, intensity is higher, the degree of crook of warp is larger, and loss of strength is also larger, and current individual layer plain weave canvas strength is generally at below 630N/mm.
Client needs the band period of the day from 11 p.m. to 1 a.m of more high strength, and the method for lamination can only be adopted to improve intensity, and multilayer skeleton is through head roll, because rate in the wrong half is through difference, stressed not identical between every layer, so the number of plies is more, flex life is poorer, more easily occurs delamination problems.Intensity will improve, and the number of plies will reduce, and this is the development tendency of current layering load-transfer device product structure.Common plain weave structure limits the raising of intensity, and higher straight of rate of utilization of strength must be adopted to be used as framework material through structure.
Directly form primarily of stressed warp, connection warp, parallel three part through canvas, it is upper and lower that its parallel is positioned at warp, fixes mutual alignment by connecting warp top-bottom cross.Stressed warp is in straightened condition all the time.Compared with plain weave structure, the rate of utilization of strength directly through structure is higher, increasing substantially of monolayer strengths, and framework material can be made to reduce to one deck.The straight warp conveyor belt be made up of it has the advantage that elongation is little, thickness is thin, intensity is high, and its single layer cloth intensity is up to 4000N/mm, is highly suitable for the condition occasion of long haul distance, large conveying quantity.
But straight warp conveyor belt strength of joint problem is difficult to solve always.The straight warp conveyor belt number of plies is generally no more than 2 layers, if use traditional step-lap heat cure mode, the loss of strength of joint will be very large; Again because straight warp conveyor belt parallel intensity is low, adopt mechanical splice also inapplicable, then finger-type joint can only be selected to connect straight warp conveyor belt.But show through the test of strength of joint test, the fracture position of finger-type joint is general all follows at finger, because the effective stressed warp in this position is minimum, rupture time refer to both sides have an appointment 20% warp be drawn out of, when reaching the maximum holding capacity limit of straight warp conveyor belt, the warp be really pulled off only has about 80%.This means under such ideal conditions, and the intensity of existing straight conveyor belt finger-model connector is maximum also can only reach 80% of straight warp conveyor belt self-strength.
Summary of the invention
The object of the invention is to the defect for above-mentioned existence and a kind of straight conveyor belt finger-model connector and preparation method thereof is provided, this kind of straight conveyor belt finger-model connector improves strength of joint, by increasing tissue layer with the warp-wise intensity of covering the loss, strength of joint is made to be equal to the self-strength of straight warp conveyor belt, and make other part thickness of joint area and straight warp conveyor belt equal, joint uniform force, softness, anti-fatigue performance are good, and the preparation method of this kind of straight conveyor belt finger-model connector is simple, be easy to operation.
Technical scheme of the present invention is: a kind of straight conveyor belt finger-model connector, comprises straight through finger-model skeleton structure, this straight warp
Finger-model skeleton structure comprises straight through canvas layer; On the surface of finger-model skeleton structure, sticking adhesive layer is had straight; Sticking adhesive layer has had the tissue layer of booster action; Tissue layer there is covering glue layer.
Its material of tissue layer is steel curtain net or aramid fiber eyelet fabric.
The intensity of tissue layer is 10% ~ 20% of straight warp conveyor belt intensity.
The length of tissue layer is 1000mm ~ 3000mm.
Tissue layer warp-wise is parallel with straight warp conveyor belt warp-wise.
The thickness of sticking adhesive layer is 1 ~ 2mm.
The preparation method of described straight conveyor belt finger-model connector, comprises the following steps:
(1) stripping of rubber cover: the rubber cover up and down peelling off straight warp conveyor belt joint area;
(2) cleaning of residual gum: first glue more than straight warp conveyor belt framework material surface is pruned, then by crude for the rubber polishing around the surface of straight warp conveyor belt framework material and groove, clean with hairbrush cleaning, remove trickle particle with air blower again, and drying is carried out to straight warp conveyor belt framework material surface;
(3) cutting of finger-type: will the tip side of two straight warp conveyor belts of joint be needed to align, then does finger-type mark on two straight warp conveyor belts, finally cuts according to done finger-type mark, is removed by the redundance under cutting, obtain finger-type tip side;
(4) brushing of rubber cement: with the surface of 120# gasoline cleaning finger-type tip side, brushing rubber cement after gasoline dries;
(5) splicing of finger-type: alignd along midperpendicalar by the finger-type tip side of two brushing rubber cements respectively, intersects docking, and the gap place of intersection reserves 2mm space, and gap adhesive tape is filled, and obtains straight through finger-model skeleton structure;
(6) finger-type joint is shaping: use the thick rubberizing of 1 ~ 2mm to be covered in directly through two surfaces up and down of finger-model skeleton structure, spread tissue layer after compacting, tissue layer is longitudinally parallel longitudinal with straight warp conveyor belt, is finally covered with rubber cover, obtains finger-type joint;
(7) sulfuration of finger-type joint: with two surfaces up and down of silicone oil paper protection finger-type joint, finger-type joint is put into vulcanizer Pressurized-heated and carries out sulfuration, wherein vulcanization process condition is: straight warp conveyor belt surface pressure is 2.0Mpa, curing temperature is 140 ~ 147 DEG C, time of cure is 20 ~ 40min, and compression ratio is 90%; After time of cure to be achieved, stop heating, pressure releasing die sinking again when allowing below finger-type joint Temperature fall to 70 DEG C, obtains straight conveyor belt finger-model connector.
Beneficial effect of the present invention is: the present invention is by increasing tissue layer to make up the warp loss of strength caused because making joint in the straight upper and lower surface through finger-model skeleton structure, enhance strength of joint, make strength of joint be equal to the self-strength of straight warp conveyor belt, joint efficiency reaches 100%.Tissue layer selects steel curtain net or aramid fiber eyelet fabric, and during pressurization, pressure transmission is more even, the sizing materials such as adhesive tape can fully fill joint respectively refer between gap, after sulfuration, each point is stressed more even.The tissue layer selected is high through line strength, and thickness is thin, and laying rear joint area thickness still can be identical with straight warp conveyor belt its thickness, be conducive to the operation of delivery system clearing apparatus, and joint flexible is good, and when crossing roller, anti-fatigue performance is good.
Tissue layer can protect joint respectively to refer to not be subjected to displacement in sizing material flow process, plays a part permanent joint and respectively refers to relative position.
Strength of joint improves the use safety coefficient that can improve load-transfer device, reduces load-transfer device user to the fund input of delivery system.The raising of joint quality, extends the service life of load-transfer device, decreases the maintenance of load-transfer device, changes the frequency, reduce use cost.
