The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0028] Embodiment 1

[0029] A medium density fiberboard paving and pre-pressing device, as Figures 1-4As shown in the figure, it includes a chassis 1. To solve the problem of automatic feeding and discharging, a pre-pressing box 4 is installed between the two chassis 1. A telescopic cylinder 16 is installed inside the pre-pressing box 4. The output end of the telescopic cylinder 16 is installed with a second bracket 17. A number of small wheels 18 are installed on the second bracket 17 in a gradient manner. A pre-pressing platform is arranged above the second bracket 17 inside the pre-pressing box 4. Through holes are provided on the pre-pressing platform. A first motor 5 is installed on the right chassis 1, and a second motor 6 is installed on the left chassis 1. A number of driving wheels 15 are rotatably installed on both chassis 1. A first conveyor belt 7 is arranged on the surfaces of the number of driving wheels 15 installed on the right chassis 1, and a second conveyor belt 8 is arranged on the surfaces of the number of driving wheels 15 installed on the left chassis 1.

[0030] Through the above solution, the first conveyor belt can send the fiberboard into the pre-pressing box to complete automatic feeding. After pre-pressing, the telescopic cylinder moves to drive the small wheels to lift the fiberboard through the through holes. Due to the gradient arrangement of the small wheels, the fiberboard slides down from the small wheels to the second conveyor belt to complete automatic discharging.

[0031] This device is further set as follows. First brackets 2 are installed on both sides of the pre-pressing box 4. A number of hydraulic cylinders 10 are installed at the lower part of the top of the first brackets 2. A pressing plate 14 is jointly installed at the output ends of the number of hydraulic cylinders 10. A control console 11 is installed beside the chassis 1. The first motor 5, the second motor 6, the hydraulic cylinders 10 and the telescopic cylinder 16 are all electrically connected to the control console 11.

[0032] Through the above solution, the hydraulic cylinders work to drive the pressing plate to press down, so as to pre-press the fiberboard on the pre-pressing platform.

[0033] This device is further set as follows. Retaining bars 9 are installed on both sides of the first conveyor belt 7 and the second conveyor belt 8.

[0034] By setting the retaining bars, it effectively avoids the fiberboard falling out of the conveyor belt when transporting the fiberboard, affecting the working efficiency of the device.

[0035] This device is further set as follows, as Figure 4 shown in the figure. Guide plates 19 are installed at the places where the first conveyor belt 7 and the second conveyor belt 8 are respectively connected to the pre-pressing box 4.

[0036] By setting the guide plates, it effectively avoids the corners of the fiberboard being stuck in the gap between the conveyor belt and the pre-pressing box.

[0037] This device is further set as follows. Second baffle plates 12 are arranged on both sides of the pre-pressing box 4, and a first baffle plate 13 is arranged at the right end of the pre-pressing box 4.

[0038] Through the above solution, the second baffle effectively prevents the fiberboard from falling out of the pre-pressing box when being conveyed between the conveyor belt and the pre-pressing box. The first baffle effectively blocks the fiberboard during feeding, preventing the fiberboard from entering the second conveyor belt without pre-pressing.

[0039] The device is further configured as follows. As Figure 4 shown, rubber strips 20 are installed on both the left and right sides of the pre-pressing box 4.

[0040] By setting the rubber strips, it effectively prevents the fiberboard from being scratched at the corners during feeding and discharging.

[0041] The device is further configured such that a maintenance door 3 is provided in front of the pre-pressing box 4.

[0042] By providing the maintenance door, the operator can conveniently maintain the internal mechanism of the device.

[0043] Working principle: The first motor 5 drives the first conveyor belt 7 to convey the fiberboard to be pre-pressed forward. At this time, the telescopic cylinder 16 is in a contracted state, and several small wheels 18 are located below the pre-pressing platform. At this time, the first conveyor belt 7 feeds the fiberboard to be pre-pressed into the pre-pressing box 4, and the first baffle 13 blocks the fiberboard; the control console 11 controls several hydraulic cylinders 10 to apply pressure to the fiberboard as required to complete pre-pressing; after pre-pressing is completed, the telescopic cylinder 16 rises. At this time, several small wheels 18 pass through the through holes and rise to lift the fiberboard. Since several small wheels 18 are arranged in a gradient manner, the fiberboard slides down from the small wheels 18 to the second conveyor belt 8 to complete automatic discharging. The telescopic cylinder 16 contracts, and the small wheels 18 retract to start the next working cycle.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
