[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0025] Combination Figure 1 The utility model discloses a paving and forming machine for fiberboard production, comprising a paving and forming machine body 1, a mixing box 2 is installed on the top of the paving and forming machine body 1, and the mixing box 2 is connected to the inside of the paving and forming machine body 1. A feeding port is provided on the upper surface of the mixing box 2, and a top cover 3 is provided on the upper side of the mixing box 2 to seal the feeding port. Therefore, when in use, the fiberboard raw material is fed into the mixing box 2 through the feeding head by opening the top cover 3.

[0026] Combination Figure 2 and Figure 3 A motor 4 is fixedly mounted on the upper surface of the mixing box 2. In this embodiment, the motor 4 is a low-speed motor. The lower end of the output shaft of the motor 4 rotates and penetrates into the mixing box 2. The lower end of the output shaft of the motor 4 is fixedly connected to a rotating shaft 5. The outer surface of the rotating shaft 5 is provided with a plurality of movable stirring groups. The plurality of movable stirring groups are arranged in a circular array on the outer surface of the rotating shaft 5. The movable stirring group includes two hinged seats 15. The two hinged seats 15 are vertically parallel and fixedly mounted on the outer surface of the rotating shaft 5. Two rotating levers 6 are rotatably connected to the two hinged seats 15. Two vertical connecting rods 7 are arranged between the two rotating levers 6. A plurality of horizontal connecting rods 16 are arranged between the two vertical connecting rods 7.

[0027] When in use, the motor 4 is started, and the output shaft of the motor 4 synchronously drives the rotating shaft 5 to rotate, so the vertical connecting rod 7, the horizontal connecting rod 16 and the rotating lever 6 rotate with the rotating shaft 5. Therefore, when the fiberboard raw materials are put into the mixing box 1, the raw materials can be mixed, further ensuring the quality of the fiberboard after passing through the paving molding machine;

[0028] Specifically, the top wall of the mixing box 2 is fixedly connected with a ring body 8, the rotating shaft 5 is arranged at the center of the ring body 8, a sleeve ring 9 is slidably sleeved on the top rotating lever 6, a control rod 10 is hinged on the top of the sleeve ring 9, the top of the control rod 10 extends to the inner side of the ring body 8, and an annular chute 12 is provided on the inner side of the ring body 8. The vertical section of the annular chute 12 is an arc shape, and the unfolded view of the annular chute 12 is wavy (see the attached manual). Figure 3 ), a limiting sliding ball 11 is fixedly connected to one side of the control rod 10 facing the annular sliding groove 12, and the limiting sliding ball 11 extends into the annular sliding groove 12 and slides in the annular sliding groove 12;

[0029] Therefore, when the rotating shaft 5 rotates, the rotating lever 6 rotates synchronously with the rotating shaft 5, and at the same time, the control pull rod 10 drives the limiting sliding ball 11 to slide in the annular sliding groove 12. Since the unfolded view of the annular sliding groove 12 is wavy, the annular sliding ball 11 can drive the rotating lever 6 to rotate clockwise and counterclockwise when sliding along the arc surface of the annular sliding groove 12. At the same time, the sleeve ring 9 slides on the outer surface of the rotating lever 6. The above-mentioned method can make the movable stirring group deform up and down synchronously when the rotating shaft 5 rotates, so as to achieve the effect of stirring the raw materials inside the mixing box 2 up and down, further improving the mixing efficiency of the raw materials in the mixing box 2, and reducing the mixing time of the fiberboard raw materials;

[0030] Combination Figure 4A movable groove 13 is provided on one side of the rotating lever 6 close to the vertical connecting rod 7. The vertical cross section of the movable groove 13 is also arc-shaped. An movable ball 14 is fixedly connected to one end of the vertical connecting rod 7 close to the rotating lever 6. The other side of the movable ball 14 extends into the movable groove 13 and moves in the movable groove 13. Therefore, when the rotating lever 6 is tilted, the movable ball 14 moves in the movable groove 13.

[0031] Specifically, a movable ball 14 and a movable groove 13 are also provided between the transverse connecting rod 16 and the vertical connecting rod 7. This method can avoid the problem of jamming between the transverse connecting rod 16 and the vertical connecting rod 7 when the connecting rod 7 is deformed.

[0032] Working principle: the motor 4 is started, and the output shaft of the motor 4 synchronously drives the rotating shaft 5 to rotate, so the vertical connecting rod 7, the horizontal connecting rod 16 and the rotating lever 6 rotate with the rotating shaft 5, and the rotating lever 6 rotates synchronously with the rotating shaft 5. At the same time, the control pull rod 10 drives the limiting sliding ball 11 to slide in the annular groove 12. Since the unfolded diagram of the annular groove 12 is wavy, when the annular sliding ball 11 slides along the arc surface of the annular groove 12, it can drive the rotating lever 6 to rotate clockwise and counterclockwise, and at the same time, the ring 9 slides on the outer surface of the rotating lever 6.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. 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.
