[0029] Among them, the fusion mechanism 100 is used for hot melt work on the pipe, and the positioning mechanism 200 can more accurately position and fix the pipe in the horizontal direction, effectively preventing the pipe from deviating in this direction.

[0030] Specifically, the fusion mechanism 100 further comprises an anti-scald handle 104 fixedly installed outside the machine body 101, a heating head 105 fixedly installed on the side of the machine body 101 away from the anti-scald handle 104, and a plurality of mold heads 106 fixedly installed outside the heating head 105 and arranged from left to right in order to decrease.

[0031] Among them, the anti-scald handle 104 fixedly installed outside the machine body 101 can prevent the operator from directly contacting the high-temperature machine body during the movement and operation of the welding machine, ensuring the safety of the operation.

[0033] The limiting groove 204, the limiting plate 205, the clamping plate 206, the fastening screw 207, the adjusting groove 208 and the nut 209 in the positioning mechanism 200 jointly act, the limiting plate 205 moves in the limiting groove 204, the position of the clamping plate 206 can be preliminarily limited, the position of the clamping plate 206 can be further finely adjusted through the cooperation of the fastening screw 207 and the nut 209, so that the pipe is more accurately positioned and fixed in the horizontal direction, and the deviation of the pipe in the direction is effectively prevented.

[0034] Preferably, the adjusting assembly 202 comprises a damping bearing seat 202a fixedly installed outside the clamping plate 201, an arm rod 202b fixedly installed outside the damping bearing seat 202a, a damping telescopic rod 202c rotatably installed in the inner cavity of the arm rod 202b, and a rack groove rod 202d rotatably installed at the end of the damping telescopic rod 202c, and the adjusting assembly 202 further comprises a rolling tooth block 202e engaged in the groove of the rack groove rod 202d, a connecting rod 202f fixedly installed outside the rolling tooth block 202e, and a fixed block 202g fixedly installed at the bottom of the connecting rod 202f.

This kind of adjusting mode of multiple components can flexibly adjust the position and angle of positioning according to the pipe diameter, shape and welding requirements of different pipes, provide accurate pre-positioning for the pipes, and reduce the possibility of positioning deviation.

[0036] Further, the anti-deviation assembly 203 comprises a limiting ring 203a fixedly installed at the bottom of the fixed block 202g, a cavity 203b opened in the inner cavity of the limiting ring 203a, a plurality of clamping springs 203c fixedly installed in the inner cavity of the cavity 203b, a positioning bent plate 203d fixedly installed at the end of the clamping spring 203c, a limiting groove 203e fixedly installed outside the limiting ring 203a, and a limiting protrusion 203f fixedly installed outside the limiting groove 203e.

[0037] The limiting ring 203a in the anti-deviation assembly 203 provides a mounting base for the entire assembly, the clamping spring 203c in the cavity 203b has elasticity, can provide buffering when the pipe is placed, and the positioning bending plate 203d can preliminarily clamp and position the pipe, the cooperation of the limiting slot 203e and the limiting protrusion 203f limits the movement range of the positioning bending plate 203d, and ensures that the positioning bending plate 203d can stably constrain the pipe during the welding process to prevent the pipe from deviating due to factors such as heat melting pressure and vibration.

[0038] In use, first, the welding machine is placed in the working position, the height and angle of the welding machine are adjusted to a stable state by stepping on the foot pedal 103b in the supporting assembly 103, using the movable characteristics of the clamping sleeve 103a at the bottom of the supporting leg 102. The operator holds the anti-scald handle 104 to move and operate the welding machine, and places the pipe at the positioning mechanism 200;

Then, the adjusting assembly 202 starts to work, the damping telescopic rod 202c rotates and telescopes in the inner cavity of the arm lever 202b, drives the rack slot lever 202d to move, the rolling tooth block 202e engaged with the rack slot lever 202d drives the anti-deviation assembly 203 to move through the connecting rod 202f and the fixed block 202g, and according to the requirements of the pipe diameter and shape, the position and angle of the precise positioning are flexibly adjusted to complete the precise positioning;

[0040] Finally, the pipe is placed in the anti-deviation assembly 203, the clamping spring 203c provides buffering and preliminarily clamps the pipe through the positioning bending plate 203d, the limiting slot 203e cooperates with the limiting protrusion 203f to limit the movement range of the positioning bending plate 203d, and ensures that the pipe is stable and does not deviate during the welding process, and then the heating head 105 and the corresponding mold head 106 are started to perform the heat melting welding work.

[0041] In summary, the positioning mechanism 200 can accurately position and fix the pipe in the horizontal direction; in the adjusting assembly 202, the damping bearing seat 202a, the arm lever 202b, the damping telescopic rod 202c, the rack slot lever 202d, the rolling tooth block 202e, the connecting rod 202f and the fixed block 202g work cooperatively, so that the positioning operation is flexible and can accurately position according to different pipe requirements; the anti-deviation assembly 203 effectively prevents the pipe from deviating due to various factors during welding, and improves the positioning accuracy and stability of the pipe heat melting welding, and ensures the welding quality.

[0042] Example 2

[0045] In the support assembly 103, the anti-skid pad 103c at the bottom of the foot pedal 103b increases the friction with the ground, effectively prevents the welding machine from shaking due to ground sliding during the working process, and provides a stable basis for pipe positioning.

[0046] In use, when the hot melting welding machine is needed, the operator first observes the ground condition of the welding machine placement position, and if the ground is uneven, the operator stands on the foot pedal 103b, steps on the foot pedal 103b, and uses the clamping sleeve 103a to move up and down at the bottom of the support leg 102, so that the foot pedal 103b drives the clamping sleeve 103a to move up and down, and the height and angle of the welding machine are adjusted, until the welding machine reaches a stable state.

[0047] In summary, the clamping sleeve 103a is movably sleeved at the bottom of the support leg 102, so that the height of the foot pedal 103b can be flexibly adjusted to adapt to different working scenes and ground conditions, ensuring that the hot melting welding machine is placed stably.
