[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] As shown in the figure, an automatic cold rolling forming equipment for polyester fiber decorative panels includes a frame and a support frame mounted on the frame. Below the support frame is a concave bottom mold 2 connected to the frame via multiple corresponding fixing blocks 1 mounted on the frame. Above the bottom mold 2 is an upper mold 3 adapted to fit the bottom mold 2. A drive device for driving the upper mold 3 to move up and down is mounted on the support frame. The frame consists of corresponding support legs 4 and square frames 5 mounted on the support legs 4. A first reinforcing rod 6 is provided between each support leg 4, a second reinforcing rod 7 is provided between the first reinforcing rod 6 and the square frame 5, and a third reinforcing rod 8 is provided inside the square frame 5. The connection strength of the frame is improved by providing the first reinforcing rod 6, the second reinforcing rod 7, and the third reinforcing rod 8.

[0023] The driving device includes a driving cylinder 9 mounted on a support frame, and a driving plate 10 mounted on the driving cylinder 9 and fixedly connected to the upper mold 3.

[0024] It also includes a pressure sensor for monitoring the pressure of the drive cylinder 9, and a controller. The controller is a PLC. By setting up a pressure sensor for monitoring the pressure of the drive cylinder and a controller, the pressure sensor is connected to the controller via a signal connection. The controller controls the extension and retraction of the drive cylinder 9 based on the monitoring signal from the pressure sensor, thereby controlling the pressure of the drive cylinder 9. This avoids insufficient or excessive pressure in the drive cylinder, which could affect the molding quality of the finished product.

[0025] The support frame consists of two longitudinal plates 22 corresponding to each other on both sides of the frame, and a transverse plate 23 on the top of the two longitudinal plates 22.

[0026] The method of use in this embodiment is as follows: In the fully automatic production line for one-time molding of polyester fiber flame-retardant sound-absorbing board disclosed in the prior art CN206722118U, when producing polyester fiber flame-retardant sound-absorbing board, the polyester fiber board heated by the heating mechanism in the production line is transferred to the bottom mold 2. Then, the drive device is started to move the upper mold 3 downward, which cooperates with the bottom mold 2 to form a concave polyester fiber decorative board after heating. Then, the perimeter is manually cut to make it into a polyester fiber decorative board that is circular in shape and concave from the perimeter to the center, thus meeting the demand for interior decoration in the market.

[0027] Example 2

[0028] The similarities between this embodiment and Embodiment 1 will not be repeated here. The difference is that the above-mentioned automatic cold rolling forming equipment for polyester fiber decorative panels also includes a cutting device for cutting the polyester fiber decorative panels into finished products 11 after the upper mold 3 and the bottom mold 2 cooperate to cold roll the polyester fiber decorative panels.

[0029] The cutting device includes a ring 12 mounted on a frame and a bearing 13 mounted on the outer surface of the ring 12. A rotating cylinder 14 is mounted on the outer ring of the bearing 13. A driven gear 15 is mounted on the outer surface of the rotating cylinder 14. A drive motor 16 is mounted on one side of the bearing 13. A drive gear 17 is mounted on the drive motor 16 to drive the driven gear 15 to rotate. A horizontal tube 18 is mounted below the driven gear 15. A vertical tube 19 is mounted at one end of the horizontal tube 18. A cutting cylinder (not shown in the figure) connected to the controller signal is mounted inside the vertical tube 19. A telescopic rod 20 is mounted on the cutting cylinder and slidably connected to the inner wall of the vertical tube 19. A cutting blade 21 is mounted at the bottom of the telescopic rod 20.

[0030] The drive plate 10, ring 12, bearing 13, and rotating cylinder 14 described in this application are all concentric with the upper mold 3 and the bottom mold 2, and the output shaft of the drive cylinder 9 is connected to the center of the upper mold 3.

[0031] The usage method of this embodiment is the same as that of Embodiment 1, and will not be repeated here. The difference is that when the upper mold 3 descends and cooperates with the bottom mold 2 to form a concave polyester fiber decorative panel from the heated polyester fiber sheet, the controller sends a signal to the cutting cylinder in the longitudinal tube 19, driving the telescopic rod 20 to move the cutting blade 21 down to a position below the polyester fiber decorative panel. The controller then stops the cutting cylinder and sends a start signal to the drive motor 16, causing the rotating drum 14 to rotate, which in turn drives the cutting blade 21 to rotate, cutting the polyester fiber decorative panel. After the cutting blade 21 finishes cutting the polyester fiber decorative panel, the controller stops the drive motor 16 and sends a reset signal to the cutting cylinder. By setting up a cutting device, the perimeter of the polyester fiber decorative panel is automatically cut after cold rolling, eliminating the need for manual trimming, reducing labor and improving processing efficiency.

[0032] Example 3

[0033] The similarities between this embodiment and Embodiment 1 will not be repeated here. The difference lies in that the above-mentioned automatic cold rolling forming equipment for polyester fiber decorative panels further includes conveying devices for conveying polyester fiber panels, respectively arranged on both sides of the frame. Each conveying device includes a conveyor frame 24 and a conveyor belt 25 mounted on the conveyor frame 24. A rotating roller for supporting the conveyor belt 25 and a conveyor motor 26 for driving the rotating roller are correspondingly arranged on the conveyor frame 24. The conveyor motor 26 is signal-connected to a controller. When the upper mold 3 descends and cooperates with the bottom mold 2 to form a concave polyester fiber decorative panel from the heated polyester fiber panel, and when the polyester fiber decorative panel is cut, the controller sends a stop signal to the conveyor motor 26. By setting conveyor frames 24 on both sides of the frame and conveyor belts 25 on the conveyor frames, the automation of the polyester fiber decorative panel is further improved, and the labor intensity of workers is reduced. The conveyor motor driving the rotating roller is existing technology and will not be described further here. Of course, other existing conveyor belt devices can also be used, and will not be described in detail here.

[0034] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
