[0024] See also Figures 1-2 In the embodiment of the utility model, a high-density fiberboard paving device includes a workbench 1, a transmission belt 2 is provided on the upper end surface of the workbench 1, a plurality of paving grooves 3 are sequentially opened on the outer wall surface of the transmission belt 2, a crushing and feeding device 4 is provided on one side of the upper end surface of the workbench 1, and an extrusion molding device 5 is provided on the other side of the upper end surface of the workbench 1. The paving groove 3 is convenient for placing fiberboard raw materials, and the transmission belt 2 plays a role in transporting the fiberboard raw materials in the paving groove 3.

[0025] like Figure 3 and Figure 4As shown, the crushing and feeding device 4 includes a first C-shaped frame 401, which is fixedly connected to the upper end surface of the workbench 1, and the upper end surface of the first C-shaped frame 401 is provided with a crushing box 402 fixedly connected. Two crushing wheels 403 are rotatably installed in the crushing box 402, and the positions of the two crushing wheels 403 correspond to each other. Two transmission gears 4030 are sequentially provided on one side wall of the crushing box 402, and the two transmission gears 4030 are respectively connected to the two crushing wheels 403, and the two transmission gears 4030 are meshed with each other. A driving motor 404 is fixedly connected to one side wall of the crushing box 402, and the output end of the driving motor 404 is connected to a crushing wheel 403. A feeding hopper 405 is fixedly connected to the upper end surface of the crushing box 402, and a discharge pipe 406 is fixedly connected to the inner top of the first C-shaped frame 401, and the discharge pipe 406 is communicated with the crushing box 402. First, the driving motor 404 is started, and the start of the driving motor 404 drives the crushing wheel 403 connected thereto to rotate. Since the two transmission gears 4030 are respectively connected to the two crushing wheels 403 and the two transmission gears 4030 are meshed with each other, the rotation of the crushing wheel 403 drives the transmission gear 4030 connected thereto to rotate, and the rotation of the transmission gear 4030 drives the other transmission gear 4030 to rotate, and the rotation of the other transmission gear 4030 drives the crushing wheel 403 connected thereto to rotate, and then the fiberboard raw material is put into the crushing box 402 through the feed hopper 405, and the raw material put into the crushing box 402 will be crushed under the rotation of the two rotating crushing wheels 403, and the crushed raw material will fall into the paving groove 3 on the upper end surface of the transmission belt 2 through the discharge pipe 406. The setting of the crushing feed device 4 facilitates the crushing of the raw material put into the paving groove 3, so that the raw materials put into the paving groove 3 can be of the same size, thereby avoiding the problem of large raw material accumulation in the inner side of the paving groove 3 affecting the production strength and quality of the fiberboard.

The lower end surface of the workbench 1 is fixedly connected with support legs 7, and four support legs 7 are provided. The four support legs 7 are respectively located at the four corners of the lower end surface of the workbench 1. The setting of the curtain 6 reduces the powder mixed in the raw materials of the discharge pipe 406 during the discharge process, thereby causing certain health problems to nearby workers, and the support legs 7 play a role in supporting the workbench 1.

[0028] The working principle of the utility model is:

[0029] First, start the driving motor 404. The starting of the driving motor 404 drives the connected crushing wheel 403 to rotate. Since the two transmission gears 4030 are respectively connected to the two crushing wheels 403 and the two transmission gears 4030 are meshed with each other, the rotation of the crushing wheel 403 drives the connected transmission gear 4030 to rotate. The rotation of the transmission gear 4030 drives the other transmission gear 4030 to rotate. The rotation of the other transmission gear 4030 drives the connected crushing wheel 403 to rotate. Then, the fiberboard raw material is put into the crushing box 402 through the feed hopper 405. The raw material put into the crushing box 402 will be crushed under the rotation of the two rotating crushing wheels 403, and the crushed raw material will fall into the paving groove 3 on the upper end face of the transmission belt 2 through the discharge pipe 406. When the raw material in the paving groove 3 on the upper end surface of the transmission belt 2 passes through the extrusion molding device 5, the hydraulic telescopic device 502 is started. The start of the hydraulic telescopic device 502 drives the extrusion molding plate 503 to move downward. The movement of the extrusion molding plate 503 will extrude the raw material in the paving groove 3.
