Description

Technical Field

[0002] Hot melt welding devices are mainly used for welding plastic pipes and fittings. This type of device is particularly suitable for the production and welding of PE, PP, and PVDF plastic pipes and fittings. The fittings are mainly elbows, equal-diameter tees, equal-diameter crosses, Y-type tees, ball valves, and extended injection-molded short pipe fittings, which can realize hot melt welding operations.

[0003] In the existing public documents, the Chinese patent announcement number CN214164083U discloses a multi-angle plastic pipe hot melt welding machine, which is mainly provided with a sliding column on the inner side of a sliding column support plate, a translation pile on the outer side of the sliding column, a hot melt clamp device is provided between each two relative translation piles, an electric hot melt device driving motor is provided at the front end of the chassis shell, a hot melt support rod is provided at the output end of the electric hot melt device driving motor, and a hot melt device is provided at one end of the hot melt support rod. However, the hot melt welding machine still has the following defects when in use.

[0004] When a hot melt welding machine is performing hot melt welding, it is necessary to dock the pipe and the pipe fitting. For a three-way pipe, the angles of its two ends are different.

After confirming the angle position, hot melt welding can be performed on the other end of the three-way pipe again. It is difficult to quickly adjust the hot melt positions of the two ends of the three-way pipe simultaneously, so the hot melt adjustment efficiency is low, resulting in low hot melt welding efficiency.

[0043] The working principle of the hot melt welding device for multi-angle welding of the present invention is as follows:

[0044] Step 1: When the present invention is locked, the support frame 15 is fixed to the ground position by the expansion bolts, and the guide plate 1 can be supported by the support frame 15, and then the controller 23 is started, and the controller 23 starts the clamping electric cylinder 21. At the same time, the sleeve frame 20 supports the clamping electric cylinder 21, and the clamping electric cylinder 21 pushes the pressing plate 22 to move downward, and the pressing plate 22 is pressed on the upper surface of the hot-melt part 19, wherein the hot-melt part 19 is a three-way pipe fitting, and at the same time, the positioning frame 18 can provide vertical support operation for the hot-melt part 19, so that the hot-melt part 19 can be firmly squeezed and locked.

[0045] Then, the two locking electric cylinders 42 are started through the controller 23, and at the same time, the socket plate 41 supports the locking electric cylinder 42, and the locking electric cylinder 42 pushes the extrusion plate 43 to move downward. The extrusion plate 43 can move downward and be extruded on the upper surface of the outer wall of the docking part 45, wherein the docking part 45 is mainly a docking pipe, and the other extrusion plate 43 can be extruded on the upper surface of the outer wall of the other docking part 45, and the positioning plate 44 can support the bottom end position of the outer wall of the docking part 45, so that the two docking parts 45 can be firmly locked.

[0046] Step 2: When the present invention performs angle linkage adjustment, the electric cylinder 3 is supported by the guide plate 1, and the controller 23 can start the electric cylinder 3, the electric cylinder 3 drives the push block 4 to move right, the push block 4 drives the L-shaped block 5 to move right, and the L-shaped block 5 drives the connecting shaft 6 to move right. At the same time, the connecting shaft 6 can synchronously drive one end of the two articulated sleeve rods 7 to move right, and the two articulated sleeve rods 7 respectively drive the two sleeve slide rods 8 to slide right, so that the sleeve slide rods 8 slide on the inner wall of the annular groove 11, so that the two sleeve slide rods 8 can move close to each other along the inner wall of the annular groove 11. At the same time, the bracket 17 can firmly connect the guide plate 1 and the guide ring 2, and the sleeve slide bar 8 drives the two limit rings 9 to slide right, and the two limit rings 9 slide right on the guide ring 2, and at the same time, the limit ring 9 drives the sleeve ring 10 to slide right, and the sleeve slide bar 8 can synchronously drive the slide bar 14 to move right, and the slide bar 14 also drives the slide column 28 to move right, and the slide column 28 slides right along the guide groove 27 on the inner wall of the arc track 26, so that the slide bar 14 carries the support frame 30 to move right, and the support frame 30 drives the screw 33 to move right, and the screw 33 can make the sleeve block 31 move right, and the sleeve block 31 drives the hot melt heater 32 to move right, and the hot melt heater 32 can be located between the docking part 45 and one end of the hot melt part 19, and the other hot melt heater 32 can be located in the gap between the other docking part 45 and the hot melt part 19.

[0047] At the same time, the sleeve ring 10 can drive the slide frame 12 to slide rightward, and the slide frame 12 carries the guide column 40 to move rightward, the guide column 40 drives the sliding sleeve block 39 to make the socket plate 41 move rightward, the socket plate 41 drives the positioning plate 44 to move rightward, the positioning plate 44 drives the docking part 45 to move rightward, and the docking part 45 can be docked with one end of the hot melt part 19 at multiple angles. Then the slide frame 12 carries the slider 16 to slide rightward, and the slider 16 can slide rightward along the upper surface of the guide plate 1, so that the slide frame 12 drives the distance sensor 13 to slide rightward. The distance sensor 13 can sense the distance value between the distance sensor 13 and the bottom of the outer wall of the hot melt part 19. When the value sensed by the distance sensor 13 is the same as the distance value set by the controller 23, the electric cylinder 3 is turned off by the controller 23, and the angles of the two hot melt heaters 32 can be adjusted synchronously, so that the two hot melt heaters 32 can be located at the two ends of the hot melt part 19 to achieve hot melt welding operation.

[0048] Step three, when the present invention performs linked hot melting, the two reduction motors 34 are started through the controller 23, and the two reduction motors 34 respectively drive the screw 33 to rotate in the positive direction, and the screw 33 drives the sleeve block 31 to move under the action of the thread transmission force, and the sleeve block 31 can approach the hot melt part 19. At the same time, the sleeve block 31 drives the hot melt heater 32 to approach the hot melt part 19, and the two hot melt heaters 32 are respectively inserted into the outer wall positions of the two ends of the hot melt part 19, so that the outer walls of the two ends of the hot melt part 19 can be hot-melted.

[0049] Then the controller 23 starts the two reduction motors 34 to rotate in the opposite direction, and the reduction motor 34 drives the screw 33 to reverse, and the screw 33 drives the sleeve block 31 to move away from the hot-melt part 19 under the action of the thread transmission force. The sleeve block 31 drives the hot-melt heater 32 away from the hot-melt part 19, so that the two hot-melt heaters 32 are respectively inserted into the inner walls of the two docking parts 45, and the inner walls of the two docking parts 45 can be hot-melted. After hot-melting, the reduction motor 34 continues to rotate forward, so that the screw 33 drives the sleeve block 31 to move closer to the hot-melt part 19 under the action of the thread transmission force. When the hot-melt heater 32 is located between the hot-melt part 19 and the docking part 45, the controller 23 starts the lowering electric cylinder 24.

[0050] The downward electric cylinder 24 can push the downward block 25 downward, and the downward block 25 drives the arc track 26 to move downward synchronously, and the arc track 26 drives the two slip rings 29 to move downward, and the slip rings 29 drive the slide column 28 to move downward, and the slide column 28 can make the slide bar 14 move downward, and the slide bar 14 slides down along the inner wall of the sleeve slide bar 8. At the same time, the sleeve slide bar 8 drives the support frame 30 downward, and the support frame 30 drives the screw rod 33 downward, and the screw rod 33 can drive the sleeve block 31 downward, wherein the sleeve block 31 drives the hot melt heater 32 to move downward, and the hot melt heater 32 moves downward from the gap between the docking part 45 and the hot melt part 19, and the other hot melt heater 32 also moves downward synchronously.

[0051] Step 4. When the present invention performs synchronous docking, the two slide bars 14 respectively drive the two hinge blocks 35 to move downward, the hinge blocks 35 drive the hinge shaft 36 to move downward, and the hinge shaft 36 carries the bottom end of the sleeve pull rod 37 to move downward synchronously, and the sleeve pull rod 37 can make the linkage rod 38 approach the center point of the guide disk 1, the linkage rod 38 drives the sliding sleeve block 39 to approach the center point of the guide disk 1, and the other linkage rod 38 also begins to approach the center point of the guide disk 1, and the sliding sleeve block 39 slides along the outer wall of the guide column 40, and the sliding sleeve block 39 slides along the inner wall of the slide frame 12, so that the sliding sleeve block 39 drives the sleeve plate 41 to approach the center point of the guide disk 1.

[0052] The socket plate 41 makes the locking cylinder 42 approach the center point of the guide disk 1, and the socket plate 41 carries the positioning plate 44 to approach the center point of the guide disk 1. The positioning plate 44 drives the docking part 45 to be inserted into the outer wall of one end of the hot-melt part 19. At the same time, another docking part 45 is also inserted into the outer wall of the other end of the hot-melt part 19, so that the two docking parts 45 and the hot-melt part 19 can be hot-melt welded synchronously.
