When the worker rotates the extrusion welder around the pipe body, the worker needs to move the body, bend over, etc., which makes it easy for the hands to shake, affecting the quality of the welding work and increasing the difficulty of the welding work. Therefore, a plastic granule extrusion welder is urgently needed to solve the above problems. Summary of the invention

[0030] When the present invention is in use, the lifting frame moves, driving the first mounting frame, the second mounting frame and the extrusion barrel to move. After the plurality of clamping rollers contact the tube body, the lifting frame continues to move so that the clamping rollers squeeze and clamp the tube body. The plurality of clamping rollers move oppositely when squeezing and clamping the tube body. The plurality of clamping rollers move oppositely, driving the plurality of rotating rollers and the U-shaped frame to move oppositely. The U-shaped frame stretches the elastic member 1 when moving oppositely on the limit rod, thereby enhancing the stability of the tube body during welding.

[0031] The present invention, when in use, when the rotating roller encounters resistance from the external tube body and the lifting frame continues to move downward, the U-shaped frame will move within the mounting frame three, and the movement of the U-shaped frame will drive the rotating roller and the clamping roller to move, so that the distance between the clamping rollers changes, which is conducive to adapting to tubes of different widths and improving the application scope of the present invention. In the absence of external force, the U-shaped frame, the rotating roller and the clamping roller are restored to their original positions by using the elastic member one, so as to be convenient for the next use.

When the connecting piece 403 moves, the elastic piece 2 402 is deformed, so that the elastic piece 2 402 is used to pull the auxiliary wheel 1 404, so as to maintain the tightness between the synchronous belt 809 and the synchronous wheels 1 808 and 810, and avoid the synchronous belt 809 being too loose on the synchronous wheels 1 808 and 810, which is beneficial to enhance the stability of the rotating roller 109 when rotating. The auxiliary wheel 2 405 in the mounting frame 5 4 is convenient for limiting the synchronous belt 809 near the synchronous wheel 1 808, and avoids the situation that the angle between the synchronous belt 809 and the synchronous wheel 1 808 is too small. The staff adds plastic particles into the feed box 5 through the feed hole 6, and the plastic particles in the feed box 5 are filled into the extrusion barrel 801 under the action of the guide surface 7.

[0055] Working principle: turn on the external power supply, the staff puts the two external tubes on the clamping roller 10, and then the working servo motor 103 drives one of the threaded rods 101 to rotate in the fixed frame 1 when it rotates in the positive direction. The transmission structure 102 includes sprocket 1, sprocket 2 and chain. When the threaded rod 101 rotates, it drives the sprocket 1 in the transmission structure 102 to rotate. When the sprocket 1 in the transmission structure 102 rotates, it drives the chain and sprocket 2 to rotate. When the sprocket 2 in the transmission structure 102 rotates, it drives the other threaded rod 101 to rotate. When the two threaded rods 101 rotate, they drive the lifting frame 104 and two of the mounting frames 105 to move toward the tube body. When the two mounting frames 105 move, they drive the limit rods 107 in the inner wall thereof. , U-shaped frame 108, rotating roller 109 and elastic member 110 move, and when the lifting frame 104 moves, it drives the mounting frame 12, mounting frame 28 and extrusion barrel 801 to move. After the multiple clamping rollers 10 contact the tube body, the clamping rollers 10 include but are not limited to rubber rollers. The lifting frame 104 continues to move so that the clamping rollers 10 squeeze and clamp the tube body. When the multiple clamping rollers 10 squeeze and clamp the tube body, they will move in the opposite direction. When the multiple clamping rollers 10 move in the opposite direction, they drive the multiple rotating rollers 109 and U-shaped frame 108 to move in the opposite direction. When the U-shaped frame 108 moves in the opposite direction on the limit rod 107, it stretches the elastic member 110, so as to enhance the stability of the tube body during welding. At the same time, the elastic member 110 is used to 0 The U-shaped frame 108, the rotating roller 109 and the clamping roller 10 are restored to their original positions. The elastic member 110 includes but is not limited to a spiral spring, which is suitable for tubes of different widths and improves the scope of application of the present invention. The through hole 106 is provided to facilitate the chain in the transmission structure 102 to pass through the two mounting frames 3 105. When in use, the extrusion barrel 801 drives the extrusion hole 803 to move toward the gap between the two tubes when moving. When the distance between the extrusion hole 803 and the two tubes reaches the welding requirement, the staff controls the servo motor 103 to stop working, and then controls the electromagnetic coil heater 3 on the mounting frame 49 to work, and uses the electromagnetic coil heater 3 to preheat the extrusion barrel 801 and the extrusion auger 802. The staff adds plastic particles into the feed box 5 through the feed hole 6. The plastic particles in the feed box 5 are filled into the extrusion barrel 801 under the action of the guide surface 7. The staff controls the double-axis motor 804 to drive the extrusion auger 802 to rotate. When the extrusion auger 802 rotates, the plastic particles in the extrusion barrel 801 are transported to the extrusion hole 803. When the plastic particles pass through the electromagnetic coil heater 3, they are melted into liquid by the preheated extrusion barrel 801 and the extrusion auger 802. The liquid is extruded from the extrusion hole 803 to the gap between the two tubes. When the double-axis motor 804 rotates, it drives the bevel gear 1 805, the bevel gear 2 806, the rotating shaft 807, the synchronous wheel 1 808, the synchronous belt 809 and the synchronous wheel 2 810 to rotate.When the synchronous wheel 810 rotates, it drives the rotating roller 109 of its inner ring to rotate, and when the rotating roller 109 rotates, it drives the clamping roller 10 to rotate, and when the clamping roller 10 rotates, it drives the two tubes to rotate. When the two tubes rotate below the extrusion hole 803, it is convenient to change the welding position so that the gap between the two tubes is covered by the liquid squeezed out of the extrusion hole 803, which is conducive to reducing the difficulty of welding the two tubes, improving the quality of welding and the work efficiency of welding. When in use, when the rotating roller 109 fixed to the synchronous wheel 810 moves, it will drive the synchronous wheel 810 to move, and when the synchronous wheel 810 moves, it drives the synchronous belt 809 to move, and when the synchronous belt 809 moves, it drives the auxiliary wheel 1 404 to move, and the auxiliary wheel 1 404 moves. When the auxiliary wheel 1 404 moves, it drives the connecting member 403 to move. When the connecting member 403 moves, it drives the rectangular rod 401 to move in the mounting frame 5 4. When the connecting member 403 moves, it deforms the elastic member 2 402, so that the elastic member 2 402 can be used to pull the auxiliary wheel 1 404, so as to maintain the tightness between the synchronous belt 809 and the synchronous wheel 1 808 and the synchronous wheel 2 810, and avoid the synchronous belt 809 being too loose on the synchronous wheel 1 808 and the synchronous wheel 2 810, which is conducive to enhancing the stability of the rotating roller 109 when rotating. The auxiliary wheel 2 405 in the mounting frame 5 4 is convenient for limiting the synchronous belt 809 near the synchronous wheel 1 808, so as to avoid the situation where the angle between the synchronous belt 809 and the synchronous wheel 1 808 is too small.
