Dynamic device is fixing to be connected, and the right side of roller is fixing with the baffle plate being arranged on roller supporting seat right-hand member to be connected；So arrange is main
Purpose be in order to, rotated by the driving effect driving rolls of driving means, drive in the mobile offer being wound around on guide rail for bend pipe
Power, primarily serves driving bend pipe and moves back and forth on driving guide rail.
Described clamping brace seat is arranged on the limit that roller supporting seat is shorter, and pinch wheels is vertically arranged in clamping brace seat
Middle position, pinch wheels is freely rotatable；The main purpose so arranged is to be positioned the position of bend pipe by pinch wheels, because
The when that bend pipe outwards expanding in moving process, if the position not to bend pipe carries out location arises that bend pipe can not be according to
Predetermined winding guide rail moves left and right, it is impossible to ensure that bend pipe and wind are in concentric state, easily makes bend pipe sliding simultaneously
Go out to the outside driving guide rail.
Described driver element is uniformly arranged around fan-shaped base plate, and driver element presents, on winding guide rail, the inclination that relative superiority or inferiority is low
Arrange；So arrange main purpose be bend pipe during movement, due to the action of gravity of bend pipe self, make bend pipe automatic
Move to the direction of the Inner arc being wound around guide rail, play the effect utilizing gravity automatic fastening to position.
Flame envelope heater is provided with two, and one is fixedly installed on the left end driving guide rail, and another is arranged on driving
The right-hand member of guide rail；The main purpose so arranged is the temperature in order to promote anticorrosive heat-shrinkable tape surface further, improves anticorrosion
The adhesive property of pyrocondensation adhesive tape and bend pipe, makes anticorrosive heat-shrinkable adhesive tape not have alice, there are shirt rim in surface irregularity, lap-joint
Phenomenon；It is arranged on the flame envelope heater of left end, mainly bend pipe is preheated, improve the temperature of bend pipe itself；Arrange
Flame envelope heater main purpose at right-hand member is, the anticorrosive heat-shrinkable adhesive tape after winding carries out intensification heating again, carries
The secondary adhesive property of high anticorrosive heat-shrinkable adhesive tape, anticorrosive heat-shrinkable adhesive tape forms the anticorrosive coat of entirety.
Described flame envelope heater includes heating collar and shower nozzle, and heating collar is circular, and shower nozzle is arranged on the inner circle of heating collar
Zhou Shang；Flame envelope heater uses natural gas or liquefied gas to be source of the gas, is lighted a fire by hose connection, rotate and make heating on shower nozzle
Circle forms pyrosphere and bend pipe body and the anticorrosive heat-shrinkable adhesive tape after winding is carried out post bake intensification, improves and is wound around anticorrosive heat-shrinkable
The winding mass of adhesive tape.
Beneficial effects of the present invention: the technical program provides a kind of bend pipe wind with three sections of heating functions, its
Design science is reasonable, simple in construction, and winding precision is high, and using effect is good；Can solve the problem that temperature in bend pipe heating process without
Method controls, and temperature is too high makes anticorrosive heat-shrinkable adhesive tape situation about being charred occur, the too low problem that melten gel can not be made to overflow of temperature；Simultaneously
Also solving manual method heating work inefficiency, labor intensity is high, easily occurs that anticorrosive heat-shrinkable adhesive tape twines partially, is wound around not consolidation
Problem, the surface irregularity of anticorrosive heat-shrinkable adhesive tape, the problem affecting the service life of bend pipe；Substantially increase anticorrosive heat-shrinkable glue
The winding mass of band, improves work efficiency, reduces labor intensity, extend the service life of bend pipe.
