Then, the glass fiber mat to be heated and shaped is placed on the conveyor belt 6, and the electric telescopic rod 13 is started to drive the shaping roller pressing assembly to press down, thereby realizing the roller pressing operation of the glass fiber mat. At the same time, the design of the movable component and the movable seat 12 facilitates the reciprocating movement of the shaping roller pressing assembly, effectively realizing the heating and shaping of the glass fiber mat and improving the shaping efficiency of the glass fiber mat. At the same time, the design of the shielding door 3, the sliding door 14, the spring 15 and the slider 24 effectively shields the inlet and outlet 2, which can reduce the opening area of ​​the inlet and outlet 2 and thus reduce the heat loss rate.

[0022] A slider 24 is fixedly connected to the inner wall of the shielding door 3 near the housing 1. A sliding opening 14 is provided on the outer wall of the housing 1. The slider 24 slides inside the sliding opening 14. Both the slider 24 and the sliding opening 14 are T-shaped structures.

The movable shielding door 3 facilitates the movement of the slider 24 inside the sliding opening 14, effectively adjusting the position of the shielding door 3 and providing convenience for opening and blocking the inlet and outlet 2. During the heating and shaping process of the glass fiber mat, the opening area of ​​the inlet and outlet 2 can be reduced, thereby reducing the rate of heat loss.

[0023] The shaping roller pressing assembly includes a rotating shaft 18 rotatably mounted on the bottom end of the output shaft of the electric telescopic rod 13. A rotating cylinder 19 is elastically sleeved on the outer wall of the rotating shaft 18. The inner wall of the rotating cylinder 19 has symmetrically formed limit grooves.

The shaping roller 25 and the connecting plate 26 are rotatably mounted on opposite sides and fixed to the inner wall of the through groove 23. A rod 30, inserted into a slot 29, is fixedly connected to one side of the column 27 and the connecting plate 26. Both the slot 29 and the rod 30 are rectangular structures. Heating plates 31 are installed at equal intervals on the inner wall of the receiving cavity 28. Through holes 32 are opened at equal intervals on the outer wall of the shaping roller 25. A gear 20 and a fan blade 21 are fixedly sleeved on the outer wall of the rotating cylinder 19. The fan blade 21 is located between the gear 20 and the shaping pressure plate 22. A toothed plate 16 located on one side of the gear 20 is fixedly connected to the inner wall of the housing 1. The gear 20 and the toothed plate... 16. Engaging connection; By placing the shaping roller 25 equipped with heating plate 31 at the bottom of the through groove 23, the heating plate 31 is activated during shaping. The shaping roller 25 heats up through heat transfer, which facilitates the shaping pressure plate 22 to drive the shaping roller 25 to move synchronously during the movement, so that the shaping roller 25 can perform hot rolling pressing on the glass fiber mat. At the same time, the fan blade 21 will also rotate during the hot rolling pressing process, further accelerating the heat flow inside the box 1 and improving the heating and shaping efficiency of the glass fiber mat.

[0024] The moving component includes a motor 17 installed on the inner wall of the housing 1. The output shaft of the motor 17 is connected to a lead screw, which passes through the interior of the moving seat 12. The lead screw is threadedly connected to the moving seat 12, and the top of the moving seat 12 slides in contact with the inner wall of the top of the housing 1. Through the design of the moving component, it is easy to realize that the moving seat 12 drives the electric telescopic rod 13 and multiple hot press rollers to move back and forth, so as to realize the hot roll forming operation of the glass fiber mat, which effectively improves the forming quality of the glass fiber mat.

[0025] The implementation principle of the glass fiber mat heating and shaping device in this embodiment is as follows: The operator pulls the shielding door 3 upwards, opening the inlet and outlet 2 to facilitate placing the glass fiber mat to be heated and shaped at the top of the conveyor belt 6. Then, the shielding door 3 is released, and under the elastic force of the spring 15, it moves downwards to block the inlet and outlet 2, effectively reducing the opening area of ​​the inlet and outlet 2. Next, heating plates 8, 10, and 31 are activated. Through heat transfer, the support box 7 and the shaping roller 25 heat up, generating heat inside the housing 1. To avoid uneven heat distribution, the fan 11 is activated to accelerate heat flow inside the housing 1. Then, the electric telescopic rod 13 is activated, which drives the rotating shaft 18 and the rotating cylinder 19 to move downwards synchronously, causing the shaping pressure plate 22 to drive the shaping roller 25 to contact the top surface of the glass fiber mat. Simultaneously, the gear 20 moves to one side of the toothed plate 16 and engages. Finally, the motor 17 is activated. Motor 17 drives the lead screw to rotate. Through the threaded connection between the lead screw and the moving seat 12, and the sliding of the moving seat 12 against the top wall of the housing 1, the moving seat 12 drives the electric telescopic rod 13 and the shaping pressure plate 22 to move. This facilitates the shaping pressure plate 22 to drive the shaping roller 25 to roll and press the glass fiber felt on the top surface, realizing the hot rolling operation of the glass fiber felt. During the reciprocating movement of the shaping pressure plate 22, the rotating cylinder 19 and the rotating shaft 18 move synchronously. The rotating cylinder 19 drives the gear 20 to move on one side of the fan 11. Through the meshing of the gear 20 and the toothed plate 16, the gear 20 rotates. The gear 20 drives the rotating cylinder 19 to rotate. Through the limiting block and the limiting groove, the rotating shaft 18 rotates synchronously. The rotating cylinder 19 also drives the fan blade 21 to rotate. The fan blade 21 can accelerate the heat flow inside the housing 1, making the heat distribution inside the housing 1 more uniform and effectively improving the efficiency of heating and shaping the glass fiber felt.
