Toward the equipment of pipe fitting surface coating tackiness agent
Technical field
The utility model relates to a kind of equipment toward pipe fitting surface coating tackiness agent.
Background technology
The interior outer surface of steel pipe has tackiness agent not only to make it have the performances such as anticorrosion and shock resistance, but also the liquid in it can be prevented contaminated, and for this reason, the interior outer surface tackiness agent of steel pipe is widely used. In the prior art, coating steel pipe utilizes intermediate frequency furnace that steel pipe is heated to 180-200 DEG C, then the glue of extruding sheet and polyethylene are wrapped in the interior outside surface of steel pipe respectively to utilize forcing machine after being taken out by the steel pipe heated, cool when putting it in water after winding completes, namely make, after cooling, the steel pipe being coated with tackiness agent. Although the mode of this kind of coating steel pipe can also make it have the performances such as anticorrosion and shock resistance, but because of the time not only adopted in the process of the glue and polyethylene that are wound around sheet relatively long, and cost of manufacture is relatively high; In addition, because the weld seam on steel pipe protrudes from its outside surface substantially, if adopting the glue of sheet and polyethylene to make steel pipe tackiness agent, the tackiness agent at steel pipe seam position is very easily made not reach predetermined thickness, and seam between adjacent sheet glue, can be produced, so, the mode of this kind of coating tackiness agent makes steel pipe not have the performances such as ideal anticorrosion and shock resistance.
The name of No. 204278351U, Chinese patent bulletin is called that " a kind of heavy caliber anti-corrosion pipe is coated with molding machine automatically " proposes a solution. this kind of heavy caliber anti-corrosion pipe is automatically coated with molding machine and is made up of support roller device, vulcanizing plant, lifting device. support roller device wherein is made up of carrying roller base, idler machining, and carrying roller base is symmetricly set in vulcanizing plant two ends, and idler machining is installed on carrying roller base, vulcanizing plant is made up of storage powder groove, high pressure air chamber, support frame, and support frame is movably set on lifting device, and storage powder groove and high pressure air chamber are installed on support frame successively, and lifting device is made up of lifting base, lifting speed reduction motor, spiral lift, connection axle, spiral lift is rectangular is distributed in lifting base both sides, connecting axle divides left and right to be installed in lifting base both sides and be connected between spiral lift, and lifting speed reduction motor is connected with connection shaft drive. although this kind is automatically coated with molding machine and can automatically change and large-diameter steel pipe is carried out painting mould, it is fast that speed is moulded in its proposition painting, production efficiency height, there is higher innovation, but because the storage powder groove in vulcanizing plant is arranged on by the lower section of plastic-coated steel, and by high pressure air chamber, the powder in storage powder groove is sprayed onto the steel tube surface heated, the process of high pressure air chamber dusty spray must adopt very big air pressure, otherwise powder is not with good adherence of the outside surface of steel pipe, and on the one hand can increase cost of manufacture with normal atmosphere end of dusting, on the other hand because powder can not be sprayed onto the surface of steel pipe by air pressure very evenly, so, utilize this kind of tackiness agent being automatically coated with on molding machine coating steel pipe not bery even, and the uneven quality that can affect multiple-unit tube of tackiness agent, simultaneously because gas can directly contact with steel pipe in the process at end of dusting, thus the temperature of steel pipe can be reduced in a large number, and want again dusty spray after the decrease in temperature of steel pipe and can affect its quality, and the gas temperature at end of dusting can not raise, can by powder-stuck if improving gas temperature, so, utilize gas dust end also can reduce coating steel pipe quality, in addition, because storage powder groove is arranged on by the lower section of plastic-coated steel, and by high pressure air chamber, steel pipe is carried out dusty spray, so, this kind is coated with molding machine and can only be sprayed by the outside surface of steel pipe, and can not be sprayed by the inwall of steel pipe, even if utilizing spray gun to be entered in pipe by electrical control to be sprayed by pipe inwall, and the efficiency of its spraying is very low, and it is uneven also to there is spraying, affects the problems such as tube quality.
In addition, the name of No. 103920620A, Chinese patent bulletin is called that " heavy caliber plastic coated composite steel pipe is coated with and moulds, heating unit " adopt a process furnace, it is coated with molding machine structure, the conduction parts such as frame and secondary heating furnace, painting molding machine structure wherein is by feeding box, first spray unit, 2nd spray unit and powder recovery bin are formed, first spray unit and the reverse parallel setting mutually of the 2nd spray unit, first spray unit and the 2nd spray unit are made up of malleation Chui Fen mechanism and the negative pressure powder-suction structure that arranges corresponding thereto respectively, left end in malleation Chui Fen mechanism is provided with the feeding box that feeding tube is connected, right-hand member at negative pressure powder-suction structure is provided with the powder recovery bin that powder conveying pipe is connected. in the process of spraying binder, the steel pipe of process furnace heating is led down to drop on carry out two-way absorption spraying in spray body section by being conducted frame, it is directed at rotary spraying head respectively by the mouth of pipe two ends of pipe body and rotates sucker, when the first spray unit sprays, powder in feeding box is accommodated in powder tank by the whirlwind withdrawer of malleation Chui Fen mechanism, then Open valve pneumatic actuator, powder in powder tank sprays to the direction of rotary spraying head under the effect of air compressor, and the rotation sucker of negative pressure powder-suction structure is under the effect of suction fan, powder is attracted, carry out one end material spray one end suction, add pipe body along with rotary spraying head and the rotation rotating sucker, the work in-process sprayed this one end again send into the 2nd spray unit, same principle carries out the spraying of the pipe body the other end. mould although the interior outside surface of steel pipe can be carried out painting by the mode of one end material spray one end suction by this device, but the material sprayed can't spread all areas after spraying from rotary spraying head outward extending process very evenly, and gas also can reduce the temperature of steel pipe, so, adopt the coating layer degree of uniformity on this kind of device sprayed coating steel pipe also relatively poor relatively high with cost of manufacture.
