[0024] The side walls of the two vertical plates 1 on the opposite sides are fixedly connected to two bearings 9 through two brackets, and the inner circles of the two bearings 9 on the same side are commonly fixedly inserted with a driving shaft 10, and the front and rear ends of each driving shaft 10 are respectively fixedly connected with a short conveying roller 11 and a long conveying roller 12, and the outer walls of the short conveying rollers 11 and the long conveying rollers 12 on the same side of the front and rear are commonly sleeved with a conveyor belt 13, and the surface of each conveyor belt 13 is provided with a plurality of storage grooves 14 arranged at equal intervals, and the inner tops of the two conveyor belts 13 are movably fitted on the surfaces of the support plate 1 2 and the support plate 2 3 respectively. When in use, each sealing cover and the heating rod can be placed in each storage groove 14 on the conveyor belt 13 on each short conveying roller 11 and the long conveying roller 12 respectively.

[0025] An intermittent feeding mechanism and a discharge buffer mechanism are respectively provided on the side walls on the opposite sides of the two vertical plates 1. The intermittent feeding mechanism includes a gear 15 fixedly connected to the outer wall of the left driving shaft 10. A motor 16 fixedly connected to the side wall of the vertical plate 1 through a support rod is provided below the gear 15. The end of the output shaft of the motor 16 is fixedly connected to a half gear 17 meshing with the gear 15. After each sealing cover and heating rod is placed, the motor 16 is started to drive the half gear 17 to rotate, and then the intermittent meshing of the half gear 17 and the gear 15 can be used to realize the intermittent rotation of each short conveying roller 11 and the long conveying roller 12, thereby achieving intermittent conveying of each sealing cover and heating rod.

[0026] A connecting plate 8 is fixedly connected between the support plate 1 2 and the support plate 2 3, and an automatic rotary welding device is provided on the connecting plate 8. The automatic rotary welding device includes two bearings 2 19 fixedly connected to the upper side wall of the connecting plate 8, and the inner rings of the two bearings 2 19 are fixedly inserted with a welding tube 20, and the inner bottom wall of the welding tube 20 is installed with a sensor 23. When the sensor 23 senses that the heating rod and the sealing cover are aligned with the welding tube 20, the two electric telescopic rods 1 5, the electric telescopic rod 21 and the motor 25 will all start automatically, and after the motor 25 drives the welding tube 20 to rotate one circle through the gear 2 26, the driving ends of the two electric telescopic rods 1 5 and the electric telescopic rod 21 will all reset automatically, and the pneumatic clamp 7 will automatically release the already welded heating tube after resetting, and the motor 2 25 will automatically close, so that the conveyor belt 13 on the long conveying roller 12 continues to convey the assembled and welded heating tube.

[0027] The upper side wall of the welding tube 20 is penetrated by an electric telescopic rod 21, the driving end of the electric telescopic rod 21 is fixedly connected with a welder 22, the outer wall of the welder 22 is provided with a tooth groove 24, the lower side wall of the connecting plate 8 is fixedly connected with a motor 25, and the end of the output shaft of the motor 25 is fixedly connected with a gear 26 that movably penetrates the lower side wall of the connecting plate 8 and meshes with the tooth groove 24.

A spring 18 is commonly connected between the buffer plate 27 and the vertical plate 1. When the conveyor belt 13 continues to transport the welded heating tube to the right end, the heating tube can fall directly onto the buffer plate 27 under the action of its own gravity, and under the action of the spring 18, it can achieve a buffering effect on the heating tube, effectively playing a protective effect on the heating tube.
