The utility model content
For the problems referred to above, the problem that the utility model is determined with regard to quasi-solution provides the support roller that the PE tubing heat-melting butt-joint that a kind of position of roller can regulate is used, to eliminate in the bigbore tubing butt-fusion process, the different height in welding bead both sides, interface inconsistent phenomenon, guarantee the butt fusion welding quality, same footpath, coaxial, the parallel prescribed limit that reaches of tubing when making docking.
For achieving the above object, the utility model has adopted following technical scheme: a kind of PE tubing heat-melting butt-joint support roller, it comprises bearing, be fixed on two parallel bracing frames on the bearing, positioning core axle and roller, described positioning core axle and two bracing frames are rotatably connected, described roller housing is on positioning core axle, described roller has the structure that enlarges gradually to two side diameters from the centre along axis, be to have depression in the middle of on the side face of described roller, support frame as described above comprises support fixed head and movable support plate, described support fixed head is vertical with bearing fixing, described movable support plate is provided with the mandrel installing hole, and two ends of described positioning core axle are rotatably connected with the movable support plate of two bracing frames respectively; Described support fixed head can be regulated with the movable support plate and be connected.
Described support fixed head with the structure that the movable support plate can be regulated connection can be: described support fixed head and movable support plate are respectively equipped with screw corresponding more than two, screw corresponding on described support fixed head and the movable support plate wherein is provided with set bolt and hold-down nut, and the screw that wherein supports on the fixed head is the waist type.Also can be: described support fixed head and movable support plate be respectively equipped with screw corresponding more than two, and screw corresponding on described support fixed head and the movable support plate wherein is provided with bolt and hold-down nut, and wherein the screw on the movable support plate is the waist type.
Adopt said structure, PE tubing heat-melting butt-joint support roller of the present utility model, because described support fixed head can be regulated with the movable support plate and be connected, and it is vertical with bearing fixing to support fixed head, two ends of positioning core axle are rotatably connected with the movable support plate of two bracing frames respectively, by regulating the movable support plate with respect to the height that supports fixed head, can adjust the height of positioning core axle, namely the height of capable of regulating roller like this.Like this, when PE tubing heat-melting butt-joint, can regulate each support roller to unified height, to eliminate in the bigbore PE tubing butt-fusion process, the different height in welding bead both sides, interface inconsistent phenomenon, guarantee the butt fusion welding quality, same footpath, coaxial, the parallel prescribed limit that reaches of tubing when making docking.
