The inner door seal strip of an automobile is usually made of rubber material. This material has excellent elasticity and sealing performance. The cross-section of the seal strip is in a hollow shape. This design enables it to adapt to gaps of different sizes. No matter how the gap size changes, it can maintain a good sealing effect. At the same time, the softness of the rubber material also enables the seal strip to maintain a certain flexibility during installation and use, and is not easily damaged. It is widely used on the doors of various automobiles and is an important part of the automobile sealing system.

[0037] As shown in the attached Figure 2 figures, an installation groove 16 is formed inside the mounting frame 1 for installing a motor 17.

[0038] As shown in the attached Figure 7 figures, a motor 17 is fixedly installed inside the installation groove 16, the output end of the motor 17 is fixedly connected to a fixing shell 18, and a rotating plate 19 is fixedly connected to the upper surface of the fixing shell 18. The rotating plate 19 is convenient for driving the sealing strip to turn.

[0039] As shown in the attached Figure 5As shown in the figure, a gear 20 is rotatably connected to the middle of the rotating plate 19. Two stabilizing grooves 23 and two connecting grooves 21 are formed on the upper surface of the rotating plate 19. The two connecting grooves 21 are arranged between the two stabilizing grooves 23. A rack 22 is slidably connected inside the connecting groove 21. The two racks 22 are meshed with the gear 20. A clamping plate 24 is fixedly connected to the upper surface of the rack 22.

[0041] Working principle: During use, first place the sealing strip skeleton on the rotating plate 19 manually, and insert the sealing strip into the skeleton to facilitate the shaping of the sealing strip. Then, start the hydraulic cylinder 26. The output end of the hydraulic cylinder 26 retracts to drive the connecting block 27 to slide inside one of the connecting grooves 21, which is convenient for the connecting block 27 to drive the rack 22 to move.

Under the action of the skeleton, the sealing strip is heated and shaped.

[0043] When the heating is completed, first fill the inside of the cooling water tank 9 with coolant through the liquid inlet pipe 10, and then start the motor 17, so that the motor 17 drives the rotating plate 19 to turn again, so that the heated sealing strip rotates into the inside of the fixing frame 12 and is above the cooling water tank 9. Then, start the cooling fan 14. It is convenient for the cooling fan 14 to also suck air through the dust-proof plate 15 and blow it to the lower part of the fixing frame 12 to blow the sealing strip, and with the auxiliary effect of the cooling water tank 9, it is convenient to accelerate the dissipation of the heat on the sealing strip, so as to accelerate the cooling speed.
