Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Such as Fig. 1, Fig. 1 is the aramid fiber conveying belt and PVG conveyer belt bridging method flow charts of the present invention, this bridging method bag
Include following steps：
S101:The aramid fiber of reserved aramid fiber conveying belt joint；Divest the first core rubber at PVG conveying band joints and
One rubber cover, PVG belt carcass is formed, and jack hole is made on PVG belt carcass.
This step is the preprocessing process before actual overlap joint is carried out.In practical application, the aramid fiber of aramid fiber conveying belt
Layer (the namely sandwich layer of aramid fiber conveying belt) is very thin, and joint is obtained by way of divesting the first core rubber and the first rubber cover
Aramid fiber is simultaneously inconvenient, therefore can directly order joint and have the aramid fiber conveying belt of reserved setting length aramid fiber.Should
Pay attention to, the aramid fiber of described end should be the virtue along warp direction sub-wire thread and in weft direction without connection herein
Synthetic fibre fiber..
Because PVG conveyer belts are the conveyer belt sections that are used on belt conveyor, and have between its rubber cover and PVG belt carcass
More clearly border, therefore can be by way of external force is pullled by the first rubber cover and first of PVG conveyer belt end regions
Core rubber directly removes, and obtains the PVG belt carcass of setting length.
S102:Aramid fiber passes through jack hole, the aramid fiber conveying belt seam is woven on the PVG belt carcass；
In this step, aramid fiber through the jack hole on PVG belt carcass to stitch by being woven on PVG belt carcass.Due to
After there is more jack hole, every aramid fiber to pass through multiple jack holes on PVG belt carcass, when tensing aramid fiber again, virtue
Synthetic fibre fiber is locked on PVG belt carcass in multiple S types, can bear a certain degree of tightening force.
During actual seam is knitted, aramid fiber can sequentially pass through corresponding jack hole along the warp direction of whole conveyer belt
(also just every aramid fiber is woven on PVG belt carcass along warp direction seam, occurs without cross one another situation), so makes processing
After the completion of whole conveyer belt simply in warp direction stress, reduce weft direction stress, prevent conveyer belt along weft direction
The problem of contraction distortion.Certainly, in other embodiments, as weaving method is relatively reasonable, conveyer belt can be prevented in broadwise
Direction distortion, it can also be changed to other weaving methods.In addition, it is also noted that when aramid fiber is woven on PVG belt carcass, should protect
The inboard outside uniform force of card is consistent.
S103:Lay the second core rubber and the second rubber cover successively respectively on the two sides of PVG belt carcass, vulcanize the second core rubber and the
Two rubber covers.
Aramid fiber seam is woven in after PVG belt carcass, it is necessary to cover corresponding second core rubber improve whole aramid fiber and
The bonding strength of PVG belt carcass while improve impact resistance；It is then to improve the resistance to of whole conveyer belt to lay the second rubber cover
Intensity is ground, and then improves the service life of conveyer belt.Above-mentioned the second core rubber being laid on PVG belt carcass and the second rubber cover are
Rubber, i.e., crosslinking curing is not carried out；By above rubber lay after the completion of, for realize the bonding of the second core rubber and PVG belt carcass,
Improve the second core rubber and the structural strength of the second rubber cover, it is also necessary to use and vulcanized.Due to the field erected limit of conveyer belt
Make, it is more in sulfidation directly to be vulcanized using equipment such as vulcanizing boards.
In the present invention is embodied, in addition to using above step, to improve the latitudinal strength of lap-joint in actual production,
Weft direction deformation of the conveyer belt on ribbon conveyer is prevented, can also be before the second core rubber and the second rubber cover is laid
The two sides broadwise laying nylon cord fabrics of PVG belt carcass, lap-joint's latitudinal strength is supported by nylon cord fabrics.Certainly, it is specific at other
In implementation, even if being not provided with nylon cord, the joint of aramid fiber conveying belt and PVG conveyer belts can also be knitted viscous with core rubber by seam
Connect and be preferably fixed together.
In addition, further to improve the bonding strength of aramid fiber, prevent from causing aramid fiber because moment pulling force is excessive
The problem of departing from jack hole, the free end of aramid fiber can also be fixed by knotting.Wherein knotting fixed form can be adjacent
Knot and link together between aramid fiber, the free end system of aramid fiber can be also connected on itself.
As existing PVG conveyer belts subregion heavy wear, need removable parts PVG conveyer belts when, directly using upper
State method and correspondent section is replaced with into aramid fiber conveying belt, realize the progressively replacement of existing PVG conveyer belts, avoid changing all
The great amount of cost that conveyer belt is formed.A batch connected mode is connect relative to existing, can preferably be improved using above-mentioned connection method
Aramid fiber conveying belt and the bonding strength of PVG conveyer belts lap-joint, avoid because the two thickness difference it is larger caused by connection it is insecure
Problem.Through actual test, the strength of joint that this method is formed reaches the 85% of PVG belt intensions.It is contemplated that due to using
Aramid fiber conveying belt itself is lighter, can reduce ribbon conveyer and start load and performance load, improve the service life of conveyer belt.
In actual production, to ensure that conveyer belt can seamlessly transit, surface is prevented to be partially formed boss, in vulcanization second
After core rubber and the second rubber cover, it is also necessary to foregoing second rubber cover of correction of the flank shape of polishing.
The aramid fiber conveying belt to the specific embodiment of the invention and PVG conveyer belt bridging methods explain above, can make ability
Domain professional and technical personnel can realize or using the present invention.For those skilled in the art, to these embodiments
A variety of modifications will be apparent, and generic principles defined herein can not depart from the spirit or scope of the present invention
In the case of, realize in other embodiments.Therefore, the present invention is not intended to be limited to the embodiments shown herein, but
