The back of the transmission member 1 51 is rotatably connected to the connecting plate 2, one end of the folding plate 57 is connected to the connecting plate 2, the back of the triangular support member 52 is rotatably connected to one end of the reciprocating threaded rod 54, the inner wall of the circular ring 53 is threadedly connected to the outer wall of the reciprocating threaded rod 54, the top of the circular ring 53 is connected to the support rod 55, the top of the support rod 55 is installed with a heating element 56, and the support rod 55 passes through the interior of the long slot 3.

[0032] Preferably, the transmission mechanism 6 includes a second transmission member 61, two side gears 62 are arranged on the back of the second transmission member 61, a central gear 63 is meshed and connected between the two side gears 62, a disc 64 is fixedly connected to the back of the side gear 62, and a transmission rod 65 is fixedly connected to the front of the disc 64. A connecting ring 66 is fixedly connected to the middle of the second transmission member 61, the middle of the connecting ring 66 movably passes through the connecting plate 2 and is fixedly connected to the side gear 62, the middle of the connecting ring 66 is rotatably connected to the connecting plate 2, and the transmission rod 65 passes through the second transmission member 61 and the side gear 62. The pushing mechanism 7 includes a bevel gear 1 71, the front of the bevel gear 1 71 is meshedly connected with a bevel gear 2 72, the middle of the bevel gear 2 72 is connected with an internal thread ring 73, the middle of the internal thread ring 73 is threadedly connected with a reciprocating threaded long rod 74, a through slot 75 is provided at the top of the reciprocating threaded long rod 74, both sides of the inner wall of the through slot 75 are provided with a slide slot 76, a slide bar 77 is slidably connected inside the slide slot 76, and a connecting frame 78 is connected to one side of the slide bar 77. The back of the bevel gear 1 71 is connected to one end of the transmission rod 65, one end of the connecting frame 78 is rotatably connected to the bevel gear 2 72, the other end of the connecting frame 78 is connected to the connecting plate 2, one end of the reciprocating threaded long rod 74 is connected with an L-shaped frame 79, and the middle of the L-shaped frame 79 is slidably connected to the inner wall of the movable groove 9. The heat capacity mechanism is also equipped with a controller, and after being started by the controller, the driving component driving member 45 drives the rotating disk 41 to rotate. When the rotating disk 41 rotates, the rotating rod 43 connected to the front of the rotating disk 41 will be accurately inserted into the gap of the transmission member 1 51. The single rotating rod 43 rotates counterclockwise by 90 degrees, which can push the transmission member 1 51 to rotate counterclockwise by 90 degrees synchronously, and this action in turn triggers the rotation of the reciprocating threaded rod 54. As the ring 53 moves toward the front of the device in the middle of the triangular support member 52, it will push the support rod 55 and the heating member 56 to move toward the front of the device until the heating member 56 moves between the two clamping mechanisms 8.

[0033] When the first rotating rod 43 completes a counterclockwise rotation of 90 degrees and pushes the transmission member 1 51, the round rod 44 connected to its back side will be inserted into the interior of the transmission member 2 61, thereby pushing the transmission member 2 61 to rotate 90 degrees clockwise. This rotation action will drive the corresponding side gear 62 to rotate 90 degrees counterclockwise, and realize the synchronous clockwise rotation of the other side gear 62 by 90 degrees through the central gear 63 set in the middle, thereby driving the two transmission rods 65 to rotate synchronously. This series of actions will cause the two bevel gears 1 71 to rotate 90 degrees towards each other at the same time, thereby driving the two bevel gears 2 72 to rotate, so that the two reciprocating threaded long rods 74 approach each other, and finally drive the two clamping mechanism 8-shaped parts set on the top to approach each other. At this time, the PA connecting ring 66 composite material assembled inside the two clamping mechanism 8-shaped parts will fit on both sides of the heating element of the heating member 56 to heat the ends.

[0034] Subsequently, the rotating disk 41 continues to rotate clockwise, and the rotating rod 43 connected to the other side thereof will be inserted into the groove position corresponding to the transmission member 1 51, pushing the transmission member 1 51 to rotate again, and driving the reciprocating threaded rod 54 to rotate. At this time, the support rod 55 will move to the back of the device, driving the heating element 56 to return to its original position. After the rotating rod 43 rotates ninety degrees, the round rod 44 arranged on the back thereof will be inserted into the groove corresponding to the transmission member 2 61, driving the transmission member 2 61 to rotate ninety degrees again, and then driving the side gear 62 and the transmission rod 65 to move through the transmission member 2 61, so that the two reciprocating threaded long rods 74 continue to approach, and finally the PA connecting ring 66 composite materials assembled inside the two clamping mechanisms 8 are fitted together for connection.

[0035] After the connection is completed, the staff can take out the assembled PA connection ring 66 composite material. At this time, the rotating disk 41 is allowed to rotate idly for one circle, so that the clamping mechanism 8-shaped component can be restored to its original position, ready for the next hot melt connection operation. It is worth noting that the heating element 56, as a heating element, plays a key role in the whole process, and the driving element 45 rotates in a regular intermittent manner to ensure the smooth progress of the whole hot melt connection process.

[0036] Preferably, the clamping mechanism 8 comprises a bottom plate 81, a housing 82 is mounted on the top of the bottom plate 81, a fixing frame 83 is arranged at the bottom of the bottom plate 81, a telescopic rod 84 is arranged on one side of the fixing frame 83, a moving rod 85 is penetrated inside the housing 82, a rotating wheel 86 is meshedly connected to the middle of the moving rod 85, a rotating rod 87 is connected to one end of the rotating wheel 86, a spring 88 is sleeved on the top of the moving rod 85, and a fixing piece 89 is arranged on one side of the rotating rod 87. The bottom of the bottom plate 81 is connected to the L-shaped frame 79, the bottom of the fixing frame 83 is connected to the top of the L-shaped frame 79, one side of the telescopic rod 84 is connected to one side of the L-shaped frame 79, the rotating wheel 86 is installed inside the housing 82, the bottom end of the spring 88 is fitted with the top of the housing 82, and one end of the fixing piece 89 is connected to the outer wall of the housing 82. The PA connecting ring 66 composite material is properly placed inside the fixing frame 83 to ensure that one end thereof is tightly fitted to the telescopic rod 84. Then, the rotating rod 87 is rotated downward to bypass the fixing member 89 and move to the bottom thereof. It is worth noting that grooves are provided on the corresponding surfaces of the moving rod 85 and the rotating wheel 86 to engage with the teeth of the moving rod 85. Therefore, when the rotating rod 87 is rotated downward, the rotating wheel 86 is driven to rotate synchronously, thereby pushing the moving rod 85 to move downward until it is engaged with the top of the composite material of the PA connecting ring 66, thereby achieving a stable fixing effect.

[0037] Once the controller is started and the rotating disk 41 starts to rotate, the telescopic rod 84 will automatically retract downward and no longer block the end of the PA connection ring 66 composite material, making room for the hot-melt connection process. After the hot-melt connection of the PA connection ring 66 composite material is successfully completed, the operation becomes extremely simple: just gently move the rotating rod 87 away from one side of the fixing member 89, and the spring 88 will quickly bounce upward, using its elastic force to push the moving rod 85 and the rotating rod 87 back to their original positions automatically, fully preparing for the next operation.

[0038] This design not only ensures the stability and accuracy of the PA connecting ring 66 composite material during the hot melt connection process, but also greatly improves the convenience and efficiency of operation.
