[0034] In this embodiment, in order to achieve the effect of pre-pressing and pushing the flame retardant board outward, a pre-pressing conveying assembly 4 is designed. Two groups of pressing conveying rollers 4-1 are arranged on the main frame 1, each group consists of two rollers, which are driven to rotate by a motor to convey and pre-press the flame retardant board. Two laminating plates 4-2 with heating tubes 4-3 are arranged in the main frame 1, which can be heated during the conveying and pre-pressing process to improve the pressing effect. A bottom opening 4-4 ​​is provided at the bottom of the main frame 1, and a telescopic cylinder 4-5 is installed at the bottom. The output end of the telescopic cylinder 4-5 is connected to a connecting block 4-6 and is provided with a groove 4-7. A pusher 4-7 is rotatably connected in the groove 4-7.

The flame retardant plate can push against the pushing plate 4-8 during movement, and the pushing plate 4-8 is rotated downward through the rotating connection and retracted into the bottom opening 4-4. After the bottom of the flame retardant plate is separated from the pushing plate 4-8, the reset spring 4-10 can pull the pushing plate 4-8 to return to a vertical state, and then the flame retardant plate can be pushed by the control of the telescopic cylinder 4-5.

[0035] Furthermore, connecting sleeves 5 are provided on both side surfaces of the pressing box 3 - 6 , and the cross section of the connecting sleeves 5 is a rectangular structure.

[0036] In this embodiment, rectangular connecting sleeves 5 are provided on both sides of the pressing box 3-6 for inserting into the front fork of a forklift. After the insertion, the pressing box 3-6 can be lifted for loading and unloading.

[0037] Furthermore, a pair of pulleys 6 are provided on the side end surfaces of the movable seat 3 - 4 , and the pulleys 6 are attached to the surface of the sub-frame 2 .

[0038] In this embodiment, two pulleys 6 are installed on one side of the moving seat 3 - 4 so that the moving seat 3 - 4 can be supported on the surface of the sub-frame 2 when moving, thereby achieving the effect of supporting the movement.

[0039] Furthermore, a scraper groove 7 is provided on the surface of the main frame 1, and the inner surface of the scraper groove 7 is an inclined structure.

[0040] In this embodiment, by providing the scraping glue groove 7, the glue overflowing from the bottom can be scraped off during the conveying process of the flame retardant board to avoid remaining on the surface of the main frame 1 and affecting the subsequent movement of the flame retardant board.

[0041] Furthermore, the opening size of the bottom opening 4-4 ​​is smaller than the thickness of the flame retardant board, and the inner surface of the main frame 1 and the inner bottom surface of the pressing box 3-6 are located at the same plane height.

[0042] In this embodiment, the bottom opening 4-4 ​​is smaller than the thickness of the flame retardant board, so that the flame retardant board will not fall into the bottom opening 4-4 ​​when moving. The same plane height is used to ensure that the flame retardant board can stably slide into the pressing box 3-6.

[0043] When it is necessary to press the flame retardant board, the laminated flame retardant board enters between the pressing and conveying rollers 4-1 in the main frame 1, and the pressing and conveying rollers 4-1 and the heating tube 4-3 are started to convey, press and heat at the same time. During the movement of the flame retardant board, the push plate 4-8 is rotated downward and retracted into the bottom mouth 4-4. After the bottom of the flame retardant board is separated from the push plate 4-8, the telescopic cylinder 4-5 is started to make the push plate 4-8 push the flame retardant board into the pressing box 3-6, and then the driving screw 3-2 is started to move the pressing box 3-6 one position. After it is fully filled, the hydraulic cylinder 3-13 is started to press the pressing plate 3-14 against the splint 3-9, and the support spring 3-10 cooperates to shrink. After it is fully pressed, use a forklift to insert it into the connecting sleeve 5, and then remove the pressing box 3-6 and replace it with an empty one.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
