[0022] like Figure 1 As shown, the utility model proposes a pipe joint rotary melting support device, including a horizontal rotary melting machine 1. The horizontal rotary melting machine 1 is a purchased part. Its principle is that the output end rotates at a high speed, so that the plastic parts in contact with it are heated due to the high-speed rotation, so that the plastic parts are melted and connected to the joint, and the connection is achieved after cooling. Its specific structure will not be repeated in this application.

[0023] like Figure 2 As shown, a stand 2 is provided at the output end of the horizontal rotary melting machine 1, a support plate 3 is provided on the stand 2, a pipe clamping and positioning device is provided on the stand 2, and the pipe clamping and positioning device includes at least two groups of fixed blocks 4 fixed to one side of the support plate 3, a movable block 5 is provided on the opposite side of the fixed block 4, a slide rail is provided between the lower part of the movable block 5 and the support plate 3, so that the movable block 5 is more stable when it is close to the fixed block 4, and a push-pull cylinder 19 is connected to the movable block 5, and the push-pull cylinder 19 pushes the movable block 5 Approaching or moving away from the fixed block 4, the movable block 5 and the fixed block 4 position the pipe to be welded, and the pipe to be welded extends out of one side of the support plate 3; when the pipe is placed between the movable block 5 and the fixed block 4, the output end of the push-pull cylinder 19 extends out to drive the movable block 5 to move toward the fixed block 4 to clamp the pipe between the two. An arc structure is provided on the opposite surfaces of the movable block 5 and the fixed block 4 to facilitate better clamping. When pipes of different diameters need to be clamped, the movable block 5 and the fixed block 4 are replaced to adjust different arc radii.

[0024] like Figure 3As shown, before the pipe is fixed, in order to determine the extended length of the pipe, a lifting cylinder 8 is provided between the output end of the horizontal rotary melting machine 1 and the support plate 3, and a limit plate 9 is provided at the output end of the lifting cylinder 8. The lifting cylinder 8 pushes the limit plate 9 to extend to the end of the pipe to be welded. After the pipe is placed, the pipe is pushed until the end of the pipe points to one end of the horizontal rotary melting machine 1 and extends a certain length from the support plate 3. The lifting cylinder 8 lifts the limit plate 9, and the end of the pipe is pressed against the limit plate 9 to limit the extended length of the pipe. A CCD camera 10 and a light source 11 are respectively provided on both sides of the welding end of the pipe to be welded. In the figure, the light source 11 is arranged on the opposite side of the CCD camera 10 and fixed on the plate body (the light source is blocked by the plate body and not drawn). The position of the light source 11 can be adjusted by the cylinder, and the CCD camera 10 is used to shoot to determine whether the pipe is extended, and then the pipe is positioned by the movable block 5 and the fixed block 4.

[0025] The joint is positioned by a joint positioning fixture 7 provided at the output end of the horizontal rotary melting machine 1, and is directed to the end of the pipe to be welded extending out of the support plate 3. The joint positioning fixture includes an annular sleeve 27, and the mouth of the annular sleeve 27 is evenly arranged with limiting notches 28. The protrusions around the joint are pressed into the limiting notches 28 to facilitate the positioning of the joint. When in use, the output end of the horizontal rotary melting machine 1 positions the joint, extends out and presses on the end of the pipe, and rotates at high speed, so that the end of the pipe melts at high temperature, and is connected with the joint after cooling.

[0026] In order to reduce the gas generated by plastic melting, a movable protective mechanism 12 is provided on the side of the support platform, and the movable protective mechanism 12 includes a support frame 13, and a linkage rod 15 is connected to the support frame 13 through a rotating shaft 14.

The push-pull cylinder 19 is horizontally arranged on the support frame 13. When working, the push-pull cylinder 19 extends out to push the linkage rod 15 to rotate, thereby driving the protective cover 16 to press down the upper part of the pipe fitting rotation melting position.

After welding is completed, it can be recovered by the push-pull cylinder 19, and the linkage rod 15 is pulled to rotate, and the protective cover 16 is flipped upward.

[0027] It should be noted that the device is suitable for pipe fittings of different sizes. When processing pipe fittings of smaller lengths, after the joint is welded at one end of the pipe fitting, the pipe fitting is turned over. In order to ensure that the pipe fitting can be better stabilized, a short slide rail 20 is provided on the support plate 3. The short slide rail 20 is parallel to the extension direction of the horizontal rotary melting machine 1, and a first sliding block 21 is clamped on the short slide rail 20. A clamping block 22 is provided on the first sliding block 21, and a clamping groove 23 is fixed on the clamping block 22. The clamping groove 23 is used to clamp on the joint at the end of the pipe fitting to be welded, so as to realize the positioning of the end joint and ensure the stability of the entire pipe fitting during welding.
