The speed regulating plate 76 has a fan-shaped structure, which changes the gap between itself and the inner wall of the drive duct 72 by rotating the drive shaft 74, thereby adjusting the cross-sectional area of ​​the airflow channel. The pressure regulating valve 77 is an electromagnetic pressure regulating valve, which receives pressure feedback signals through the controller 3 and automatically adjusts the valve opening. It works in conjunction with the airflow channel of the heating tube 73 to ensure stable hot air pressure output from the nozzle 81. The heating tube 73 is equipped with a heating wire 78, which serves as a heat source to heat the air to the set temperature. The discharge pipe 79 connects the heating tube 73 and the mounting block 8, delivering hot air to the nozzle 81. The nozzles 81 in the mounting block 8 are evenly distributed to ensure that the hot air covers the heat-contact area of ​​the sheath tube 52.

It is electrically connected to the lead screw slide module 41 and the synchronous belt module 43 to realize the automatic and precise adjustment of the relative position between the hot contact mechanism 7 and the sheath tube 52. It is electrically connected to the regulating motor 5 and the rotary cylinder chuck 51 to control the rotation angle and clamping state of the sheath tube 52. It is electrically connected to the drive motor, speed regulating plate 76, pressure regulating valve 77, and heating wire 78 to regulate the flow rate, pressure, and temperature of the hot air in real time. The controller 3 realizes closed-loop control through sensor feedback data.

[0025] As a technical optimization of this utility model, the adjusting motor 5 drives the sheath tube 52 to rotate through the rotating cylinder chuck 51, and drives the heat-sealing mechanism 7 through the synchronous belt module 43 to adjust the spray height of the nozzle 81 to match the heat-sealing position of the sheath tube 52.

[0026] In practice, the adjusting motor 5 rotates the sheath tube 52 at a constant speed through the rotating cylinder chuck 51 to ensure uniform heating of the hot air; the synchronous belt module 43 drives the heat-sealing mechanism 7 to move up and down, adjusting the height of the nozzle 81 so that it is aligned with the heat-sealing point of the sheath tube 52, thereby improving the heat-sealing accuracy and efficiency.

[0027] Working principle: First, the sheath tube 52 to be heat-welded is clamped and fixed by the rotary cylinder chuck 51. The motor 5 is started and driven by the rotary cylinder chuck 51 to rotate the sheath tube 52 to the preset heat-welding angle. The controller 3 sets the heat-welding parameters such as hot air temperature, pressure, wind speed and stroke path. The controller 3 sends signals to the screw slide module 41 and the synchronous belt module 43 respectively. The screw slide module 41 drives the lifting slider 4 to move the mounting frame 42 and the sheath tube 52 in the vertical direction. The synchronous belt module 43 drives the mounting plate 6 to move the heat-welding mechanism 7 synchronously until the nozzle 81 is aligned with the heat-welding position of the sheath tube 52, completing the positioning preparation before heat-welding. Secondly, the controller 3 activates the heat-sealing mechanism 7, the retainer 75 inside the drive duct 72 supports the drive shaft 74, the drive motor on the left side of the heat-sealing mounting base 71 drives the drive shaft 74 to rotate, and the speed regulating plate 76 on the drive shaft 74 rotates synchronously. By changing the gap with the inner wall of the drive duct 72, the cross-sectional area of ​​the airflow channel is adjusted, thereby controlling the hot air flow rate. At the same time, the pressure regulating valve 77 adjusts the valve opening according to the set pressure value, and the heating wire 78 in the heating tube 73 is energized to heat the airflow, forming a hot air flow that meets the parameter requirements. The hot air is delivered to the heating tube 73 through the drive duct 72, and then precisely introduced into the inner side of the mounting block 8 through several discharge pipes 79. Finally, it is evenly sprayed from the nozzle 81 to the heat-sealing area of ​​the sheath tube 52 to achieve rheological heating pretreatment. Finally, during the continuous hot air jetting process, the controller 3, in real time, links the lead screw slide module 41 and the synchronous belt module 43 to drive the sheath tube 52 to move relative to the heat-sealing mechanism 7 according to the preset travel path, ensuring full coverage of the heat-sealing area; the regulating motor 5 continuously drives the sheath tube 52 to rotate slowly, ensuring uniform heating of the heat-sealing surface. When the heat-sealing reaches the set time, the controller 3 sequentially shuts off the heating wire 78, the drive motor, and the pressure regulating valve 77, stopping the hot air output; then the lead screw slide module 41 and the synchronous belt module 43 drive each component to reset, the rotary cylinder chuck 51 is released, and the heat-sealed sheath tube 52 is taken out, completing one automatic heat-sealing cycle.
