Description
Technical field
The present invention relates to industrial load-transfer device field, particularly relate to a kind of seamless conveying belt and manufacture method thereof.
Background technology
In the commercial production field, need a kind of high strength seamless conveying belt that specific (special) requirements is arranged, as lining surface treatment or compound with band, require this seamless conveying belt can be high temperature resistant, intensity is high, flexible little, the load-transfer device overall leveling, thickness is even, particularly requires its outside face smooth, not sticking transported material.The load-transfer device of prior art is the out of reach above-mentioned requirements also, has joint on described load-transfer device, its joint unfairness, and belt intension is not high, easy breach, also there is the phenomenon of clinging transported material in zone face, can't satisfy some specific (special) requirements in the commercial production.Therefore, people wish that urgently a kind of load-transfer device that can satisfy above-mentioned specific (special) requirements comes out.
The manufacture method of the load-transfer device of prior art for canvas core rubber conveyer belt, generally adopts the overplate mounting method; For the resin transfer band, adopt infusion process, cladding process, rolling process.Mounting method: comprise the sandwich layer moulding, at the covering glue layer of fitting on the flattening mill, operation such as on vulcanizer, vulcanize.Infusion process: belt carcass repeatedly immerses soaker, imports the plasticizing of plasticizing chamber behind the dipping PVC thickener, or pastes rubber cover, vulcanizes on vulcanizer.Cladding process: comprise paste producing, blade coating, fusion, cool off and batch; Equipment is coating machine and fusion drying room.Rolling process: PVC rolls with flattening mill with suspension method.Also having a kind of nylon base load-transfer device, is after nylon base is extruded, coating adhesive, applying overplate, cutting.Deficiency in order to top manufactured load-transfer device is: efficient is lower, and the coating degree of uniformity is poor, the difficult control of thickness, and operation is complicated.
Summary of the invention
Technical matters to be solved by this invention is, overcome above-mentioned the deficiencies in the prior art, satisfy people's the hope and the demand in load-transfer device market, a kind of seamless conveying belt is provided, this load-transfer device does not have joint, integral seamless is smooth, thickness is even, and the intensity height is flexible little, can be high temperature resistant, the not sticking transported material of outside face.
Another technical matters to be solved by this invention is, overcome said method and make the deficiency of load-transfer device, a kind of manufacture method of seamless conveying belt is provided, make load-transfer device with this method, its production efficiency is higher, waters the load-transfer device degree of uniformity unanimity of scraping, operation is simpler, equipment investment is few, can carry out super wide and/or overlength according to user's demand and make load-transfer device, satisfies the requirement of user to the super wide and/or overlength of load-transfer device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of seamless conveying belt, comprise a closed base band, this seamless conveying belt constitutes a closed intermixed layer by jointless closed base band and rubber, in closed intermixed layer outside face design one outer rubber layer is arranged, in the design of outer rubber layer outside face layer of silica gel outside is arranged, closed intermixed layer and outer rubber layer can be overall shaped into one by the mode of scraping liquid rubber at jointless closed base band top-pour, and outer layer of silica gel and outer rubber layer can closely link together by the mode of spraying liquid-state silicon gel on outer rubber layer.
In technique scheme, making the material that described jointless closed base band selects for use can be braided fabric, PVC band or other material; Described braided fabric can be woollen blanket, polyester webs, canvas or other fabric.
The present invention solves the technical scheme that another technical matters adopts: a kind of manufacture method of seamless conveying belt may further comprise the steps:
(1), select the woollen blanket of plane ring-type as jointless closed base band;
(2), two roll shaft one ends before and after the spreading machine are opened, an end of opening is inclined upwardly around the other end, jointless closed base band is enclosed within on two roll shafts, make acclivitous two roll shaft returns, and make two roll shafts position that relatively moves, with jointless closed base band tension; Design has heating apparatus and corresponding warm area on spreading machine;
(3), open spreading machine, liquid rubber is watered on the jointless closed base band, the scraper on the spreading machine is wipeed liquid rubber off, the outer rubber layer that forms a closed intermixed layer and be connected as a single entity with it;
(4), in outer rubber layer outside face spraying liquid-state silicon gel, formation one outer layer of silica gel;
(5), treat that outer layer of silica gel is solidified after, with the external layer of silica gel outside face polishing of sander machine;
(6), will be through machine under the seamless conveying belt of polishing, product warehousing.
In technique scheme, in step (2), the range of temperatures of described warm area is 100～160 ℃.
In step (3), described liquid rubber can be liquid PVC rubber.
The invention has the beneficial effects as follows: because the present invention constitutes a closed intermixed layer by jointless closed base band and rubber, in closed intermixed layer outside face design one outer rubber layer is arranged, in the design of outer rubber layer outside face layer of silica gel outside is arranged, closed intermixed layer and outer rubber layer can be overall shaped into one by the mode of scraping liquid rubber at jointless closed base band top-pour, outer layer of silica gel and outer rubber layer can closely link together by the mode of spraying liquid-state silicon gel on outer rubber layer, and the silica gel very high linear macromolecule elastomeric material that contains silicon oxygen bond that is a kind of heat stability, it has excellent anti-ozone aging, oxygen aging, the performance of light aging and Weather, thereby this load-transfer device has following advantage: 1, because closed base band non junction, so, this load-transfer device does not have joint yet, integral seamless is smooth, thickness is even, load-transfer device steadily, the phenomenon of jolting can not occur in operational process; 2, because belt outer surface is smooth smooth, so the phenomenon of transported material can not appear clinging in load-transfer device in operational process; 3, because silica gel has excellent performance, thus this belt intension height, flexible little, can be high temperature resistant, be difficult for breach; 4, this load-transfer device can carry out super wide and/or overlength customization according to user's demand, satisfies the requirement of user to the super wide and/or overlength of load-transfer device; 5, this load-transfer device is stressed evenly.Utilize method of the present invention to make seamless conveying belt, its production efficiency is higher, waters the load-transfer device degree of uniformity unanimity of scraping, operation is simpler, equipment investment is few, can carry out super wide and/or overlength according to user's demand and make load-transfer device, satisfies the requirement of user to the super wide and/or overlength of load-transfer device.
