[0061] Referring to Figures 1 to 7 The embodiment provides a gypsum board waste crushing and separating device, which comprises a rack 10, a separating roller 20, two crushing rollers 30, a plurality of feeding plates 40 and a driving mechanism 50.

[0062] The separation drum 20 is obliquely arranged on the frame 10 and can rotate on the frame 10. A plurality of separation holes 21 are uniformly arranged on the side wall of the separation drum 20. The higher end of the separation drum 20 is the feeding end, and the lower end of the separation drum 20 is the separation discharging end. The two crushing rollers 30 are arranged in parallel on the frame 10 and pass through the separation drum 20. The crushing area is between the two crushing rollers 30. The two crushing rollers 30 crush and transport the gypsum board waste falling into the crushing area.

[0063] The plurality of feeding plates 40 are connected to the inner wall of the separation drum 20 and extend along the axial direction of the separation drum 20. The driving mechanism 50 is used to drive the rotation of the separation drum 20 and is also used to drive the rotation of the two crushing rollers 30 in opposite directions. Specifically, from one direction, one of the two crushing rollers 30 rotates clockwise, and the other rotates counterclockwise.

[0064] When the device works, under the driving of the driving mechanism 50, the inclined separation drum 20 rotates on the frame 10. The gypsum board waste enters the separation drum 20 from the feeding end of the separation drum 20. As the separation drum 20 rotates, small pieces of gypsum board waste are lifted by the feeding plates 40 on the inner wall of the separation drum 20. The lifted gypsum board waste then falls in a parabolic motion into the crushing area between the two crushing rollers 30. The two crushing rollers 30 rotate under the driving of the driving mechanism 50. The two crushing rollers 30 drive the gypsum board waste to pass through the small size area (crushing area) between the two crushing rollers 30. The gypsum board waste is crushed by the two crushing rollers 30, so that the gypsum board in the surface paper is crushed to form gypsum particles. The small size gypsum particles falling from the crushing area fall from the separation holes 21 to the outside of the separation drum 20 and are transported away. The large size gypsum particles are driven by the feeding plates 40 back to the crushing area and continue to be crushed, so that the gypsum board waste is crushed into small particles and falls from the separation holes 21. The surface paper of the gypsum board waste is gradually transported from the feeding end to the separation discharging end by the rotating separation drum 20 and is separately collected and processed.

[0065] In the device, the crushing and separation of the gypsum board waste are carried out simultaneously, and the material does not need to be transported, which is more convenient. In addition, since the gypsum board waste continuously falls from a high place in the separation drum 20, the separation drum 20 is impacted and vibrated, so that the gypsum particles falling from the separation holes 21 fall more smoothly, and the probability of the separation holes 21 being blocked is reduced. Moreover, since the separation drum 20 rotates, the position of the separation holes 21 is always changing. When the blocked separation holes 21 move from the lower part to the upper part, they can be unblocked by the impact of the gypsum board waste falling on the separation drum 20 and the gravity.

[0066] In one embodiment, the feeding plate 40 is arranged obliquely. Specifically, one end of the feeding plate 40 is connected to the inner wall of the separation cylinder 20, and the end of the feeding plate 40 away from the separation sleeve is offset relative to the axis of the separation sleeve, which allows the two crushing rollers 30 to be arranged at a higher position, and the gypsum board waste block driven by the feeding plate 40 can be lifted to a higher height, so that the gypsum board waste block can fall smoothly into the crushing area between the two crushing rollers 30. In addition, the height of the gypsum board waste block is increased, so that the gypsum board particles or fragments falling have a higher kinetic energy, which can impact the separation cylinder 20 and make the separation cylinder 20 vibrate.

[0067] In one embodiment, the gypsum board waste crushing and separating device further comprises a plurality of first strips 60.

[0068] The plurality of first strips 60 are respectively and uniformly arranged on the outer walls of the two crushing rollers 30. Each first strip 60 extends on the corresponding crushing roller 30 in the axial direction of the crushing roller 30. The number of first strips 60 on the two crushing rollers 30 is the same. The first strips 60 on each crushing roller 30 correspond to the first strips 60 on the other crushing roller 30. When the two crushing rollers 30 rotate, a first extrusion gap 61 is formed between two first strips 60 on the two crushing rollers 30 that are close to each other. Specifically, the first strips 60 on the two crushing rollers 30 correspond one by one. When the gypsum board waste block falls into the space above the two crushing rollers 30, the first strips 60 on the two crushing rollers 30 drive the gypsum board waste block between the two crushing rollers 30 from both sides when they rotate, and then the first strips 60 on both sides form the first extrusion gap 61 to preliminarily extrude the gypsum board waste, so that the gypsum in the gypsum board waste block is preliminarily crushed. The outer part of the first strip 60 has an edge, which cooperates with the rotation of the crushing roller 30 to extrude the gypsum board waste block by the edge of the first strip 60, and drive the gypsum board waste block to move downward.

[0069] In one embodiment, the gypsum board waste crushing and separating device further comprises a plurality of second strips 62.

[0070] The plurality of second strips 62 are respectively and uniformly arranged on the outer walls of the two crushing rollers 30. Each second strip 62 extends on the corresponding crushing roller 30 in the axial direction of the crushing roller 30. Each second strip 62 is connected to the end of the corresponding first strip 60. When the two crushing rollers 30 rotate, a second extrusion gap 63 is formed between two second strips 62 on the two crushing rollers 30 that are close to each other. The width of the second extrusion gap 63 is smaller than the width of the first extrusion gap.

[0071] In the embodiment, the second strip-shaped block 62 can be regarded as extending the first strip-shaped block 60 in the axial direction of the crushing roller 30. The difference is that the thickness of the second strip-shaped block 62 is greater than that of the first strip-shaped block 60, so that the width of the second extrusion gap 63 is smaller than that of the first extrusion gap 61. The second extrusion gap 63 can further crush the gypsum board waste block, so that the gypsum board waste block is crushed into smaller pieces.

[0072] In an embodiment, the gypsum board waste crushing and separating device further comprises a third strip-shaped block 64.

[0073] A plurality of third strip-shaped blocks 64 are uniformly arranged on the outer walls of the two crushing rollers 30. Each third strip-shaped block 64 extends in the axial direction of the corresponding crushing roller 30. An extrusion groove 65 is formed between two adjacent third strip-shaped blocks 64 on the crushing roller 30. The third strip-shaped block 64 on the crushing roller 30 can be inserted into the extrusion groove 65 on the other crushing roller 30.

[0074] In the embodiment, the plurality of third strip-shaped blocks 64 and the crushing rollers 30 form gears, and the two gears mesh with each other. After the gypsum board waste block is crushed in two steps, the gypsum board waste block is further crushed by the third strip-shaped block 64, so that the gypsum board waste block is crushed into small particles, which can pass through the separating hole 21.

[0075] In an embodiment, the gypsum board waste crushing and separating device further comprises a plurality of annular baffles 70.

[0076] The plurality of annular baffles 70 are uniformly arranged along the axial direction of the separating drum 20. The outer ring of each annular baffle 70 is connected to the inner wall of the separating drum 20.

[0077] In the embodiment, the annular baffle 70 can limit the speed of the gypsum board waste moving in the axial direction of the separating drum 20 in the separating drum 20, so that the gypsum board waste can stay in the separating drum 20 for a sufficient time to be crushed and separated.

[0078] In an embodiment, a first rack 22 is arranged on the outer wall of each end of the separating drum 20.

[0079] The driving mechanism 50 comprises a motor 51, a first gear 52, a linkage rod 53, two second gears 54, and two third gears 55.

[0080] The motor 51 is arranged on the frame 10. The first gear 52 is coaxially connected to the output end of the motor 51. The linkage rod 53 is rotatably arranged on the frame 10. The two second gears 54 are coaxially connected to the two ends of the linkage rod 53, respectively. One of the second gears 54 is engaged with the first gear 52. The two third gears 55 are rotatably arranged on the frame 10. The third gear 55 is engaged with the second gear 54 and the first rack 22 on the same side.

[0081] In this embodiment, the motor 51 drives the separating roller 20 to rotate through the first gear 52, the second gear 54, the third gear 55 and the first rack 22 in sequence.

[0082] In one embodiment, a second rack 23 is arranged on the inner ring of the end of the separating roller 20.

[0083] The driving mechanism 50 further comprises four connecting rods 56, two fourth gears 57 and a fifth gear 58.

[0084] The four connecting rods 56 are coaxially connected to the two ends of the two crushing rollers 30 respectively, and the ends of the four connecting rods 56 away from the crushing rollers 30 are rotatably connected to the frame 10. Specifically, each end of each crushing roller 30 is connected to a connecting rod 56.

[0085] The two fourth gears 57 are sleeved on the two connecting rods 56 respectively, and the two fourth gears 57 are engaged with each other. The fifth gear 58 is rotatably arranged on the frame 10, and the fifth gear 58 is engaged with the second rack 23 and the fourth gear 57 of one of the two connecting rods 56.

[0086] In this embodiment, in the process of the motor 51 driving the separating sleeve to rotate, the separating sleeve drives the two crushing rollers 30 to rotate through the second rack 23 and the fifth gear 58.
