[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. Cut the rock wool board into small pieces for easy crushing. The protrusion on the first cam pushes the follower plate to move to the right, and the follower plate drives the transverse motor and the transverse cutting blade to move to the right synchronously to cut the rock wool board horizontally. Since there are several transverse motors, transverse cutting blades and follower plates on the guide rail, the entire rock wool board can be cut horizontally; after being cut by the transverse cutting blade and the longitudinal cutting blade, the rock wool board becomes several small pieces, which is convenient for crushing, improves the crushing efficiency and prevents the crushing equipment from getting stuck.

[0023] 2. Clean the filter screen by jetting air to prevent the filter screen from being blocked. The powdery rock wool board falls on the filter screen, and the control system simultaneously energizes and de-energizes the third spring continuously; when the third spring is energized, the whole third spring shortens, and the third spring pulls the air blowing plate to move from one end of the rectangular groove to the other end; after the third spring is de-energized, it pushes the air blowing plate to move in the reverse direction under its own elastic force; when the control system energizes and de-energizes the third spring, the electromagnetic valve in the outlet pipeline of the air storage tank is opened, so that the pressurized air in the air storage tank is conveyed to the air blowing plate through the pipeline and sprayed on the filter screen through the air blowing holes on the air blowing plate, and then the filter screen is brushed by the brush on the air blowing plate, so that the rock wool board is not easy to deposit on the filter screen, preventing the filter screen from being blocked and ensuring the normal filtering effect of the filter screen.

[0024] 3. After the rock wool board is extruded into powder, it is further crushed to make the crushed rock wool board finer. The protrusion on the outer side of the second cam pushes the extrusion plate to move towards the inner wall of the crushing box. The extrusion plate compresses the return spring, and at the same time, the extrusion plate drives the follower plate to move towards the inner wall of the crushing box. The small pieces of rock wool board are extruded through the follower plate. The follower plate compresses the first spring, and the small pieces of rock wool board are further extruded and crushed through the teeth on the extrusion plate, making the crushed rock wool board finer and improving the crushing efficiency.

[0040] Two groups of diversion plates 35 are sequentially arranged below the fixing plate 301. Two groups of crushing wheels 351 are installed between the two groups of diversion plates 35. The interiors of the two groups of crushing wheels 351 are of electric roller structures. The two groups of crushing wheels 351 are installed on the crushing box 3. A screen 352 is arranged on the lowermost diversion plate 35; A number of first magnets are arranged on the screen 352. A number of second magnets are arranged in the two groups of crushing wheels 351. The first magnets and the second magnets have different magnetic polarities.

[0041] When the two groups of crushing wheels 351 rotate, the second magnet rotates following the crushing wheels 351. When the second magnet approaches the first magnet on the screen 352, under the attraction of the magnetic field, the first magnet drives the screen 352 to protrude upward; when the second magnet moves away from the screen 352, the screen 352 drives the first magnet to protrude downward under its own elastic force. With the continuous rotation of the two groups of crushing wheels 351, the screen 352 continuously vibrates, so as to facilitate the quick passage of the crushed rock wool board through the screen 352 and prevent the screen 352 from being blocked.

[0042] The inside of the cutting cover 12 is hollow. The output shaft of the driving motor 2 is connected with a rotating shaft 201. The rotating shaft 201 is rotatably installed on the cutting cover 12. One side of the rotating shaft 201 is provided with a guide rail 121. The guide rail 121 is installed on the cutting cover 12. There are multiple groups of first cams 21. The multiple groups of first cams 21 are successively installed on the rotating shaft 201; there are a number of protrusions on one side of the first cam 21, and a transverse cutting blade 211 is arranged on the other side of the first cam 21. Multiple groups of follower plates 122 are slidably installed on the guide rail 121. Each group of follower plates 122 is connected with the guide rail 121 through a fourth spring 125. One end of the follower plate 122 is provided with a roller, and the roller abuts against the protrusion on the first cam 21. The telescopic rod of a telescopic cylinder 124 is connected to the upper side of the cutting cover 12. The telescopic cylinder 124 is installed on the support frame 113; a transverse motor 123 is installed on each follower plate 122, and the transverse cutting blade 211 is installed on the output shaft of the transverse motor 123. The transverse cutting blade 211 is a semi-circular piece; the driving motor 2, the transverse motor 123 and the crushing motor 312 are internally provided with encoders, and the encoders are electrically connected with the control system.

[0043] Working principle: The staff places the rock wool board on the conveyor belt 112 and presses the start button on the control panel 1. The crushing equipment starts, and the roller 111 drives the conveyor belt 112 to move forward, and the conveyor belt 112 drives the rock wool board to move in the direction of the cutting cover 12;

[0044] When the rock wool board moves below the cutting cover 12, the encoder in the roller 111 feeds back the displacement data of the rock wool board to the control system. The control system energizes the fourth spring 125. Each turn of the fourth spring 125 generates a magnetic field that attracts each other. This magnetic field compresses the fourth spring 125, making the overall length of the fourth spring 125 shorten. The fourth spring 125 pulls the follower plate 122 to move to the side away from the first cam 21, so that the follower plate 122 does not contact the protrusion on one side of the first cam 21;

[0045] The control system simultaneously drives the cutting cover 12 to move downward through the telescopic cylinder 124. The driving motor 2 drives a plurality of first cams 21 to rotate through the rotating shaft 201. The plurality of first cams 21 respectively drive a plurality of longitudinal cutting blades 212 to rotate accordingly. The rock wool board is cut into long strips by the plurality of longitudinal cutting blades 212. The rock wool board cut into long strips is continuously conveyed forward through the conveyor belt 112;

[0046] When the long strip-shaped rock wool board is conveyed below the transverse cutting blade 211, the encoder in the roller 111 feeds back the displacement data of the rock wool board to the control system, and the roller 111 pauses working. At this time, the long strip-shaped rock wool board is in a stationary state on the conveyor belt 112. The control system simultaneously cuts off the power supply of the fourth spring 125. The fourth spring 125 gradually elongates under its own elastic force. The fourth spring 125 pushes the follower plate 122 to move towards the side close to the first cam 21, so that the follower plate 122 abuts against the protrusion on one side of the first cam 21. The driving motor 2 continues to drive the rotating shaft 201 to rotate, and the rotating shaft 201 continues to drive the plurality of first cams 21 to rotate. The plurality of first cams 21 respectively drive the longitudinal cutting blades 212 to rotate. At this time, the longitudinal cutting blades 212 are idling, while the protrusions on the first cam 21 rotate accordingly;

[0047] When the protrusion on the first cam 21 approaches the follower plate 122, the encoder in the driving motor 2 feeds back the rotation data of the first cam 21 to the control system. The protrusion on the first cam 21 pushes the follower plate 122 to move rightward. The follower plate 122 simultaneously compresses the fourth spring 125. The follower plate 122 drives the transverse motor 123 and the transverse cutting blade 211 to move rightward synchronously to perform a transverse cut on the rock wool board. Since a plurality of transverse motors 123, transverse cutting blades 211 and follower plates 122 are arranged on the guide rail 121, the entire rock wool board can be cut transversely;

[0048] When the protrusion on the first cam 21 moves away from the follower plate 122, the fourth spring 125 is released. The fourth spring 125 pushes the follower plate 122 to move leftward. The follower plate 122 drives the transverse motor 123 and the transverse cutting blade 211 to move leftward to their original positions. After being cut by the transverse cutting blade 211 and the longitudinal cutting blade 212, the rock wool board becomes several small pieces for easy crushing treatment.

[0049] The rock wool board that has become several small pieces is conveyed into the crushing box 3 through the conveyor belt 112. The small pieces of rock wool board fall at the position between the extrusion plate 32 and the inner wall of the crushing box 3. The control system controls the crushing motor 312 to drive the transmission shaft 311 to rotate. The transmission shaft 311 drives the second cam 31 to rotate. The protrusions on the outer side and one side of the second cam 31 rotate accordingly;

[0050] When the protrusion on the outer side of the second cam 31 approaches the pressing plate 32, the protrusion on the outer side of the second cam 31 pushes the pressing plate 32 to move towards the inner wall of the crushing box 3. The pressing plate 32 compresses the reset tension spring. Meanwhile, the pressing plate 32 drives the follower plate 321 to move towards the inner wall of the crushing box 3, and the small pieces of rock wool board are extruded through the follower plate 321. The follower plate 321 compresses the first spring, and further extrudes and crushes the small pieces of rock wool board through the teeth on the pressing plate 32;

[0051] When the protrusion on the outer side of the second cam 31 moves away from the pressing plate 32, the reset tension spring is released, and the reset tension spring pushes the pressing plate 32 to move away from the inner wall of the crushing box 3. At this time, the first spring is released, and the first spring pushes the follower plate 321 to move towards the side away from the pressing plate 32. The follower plate 321 scrapes off the residual rock wool board on the teeth of the pressing plate 32. The extruded small pieces of rock wool board become powdery and fall from the position between the pressing plate 32 and the crushing box 3.

[0052] When the protrusion on one side of the second cam 31 approaches the pressure plate 341, the encoder in the crushing motor 312 feeds back the rotation data of the second cam 31 to the control system. The control system opens the solenoid valve in the air outlet 343. The protrusion on one side of the second cam 31 pushes the pressure plate 341 to move into the pressure box 34. The pressure plate 341 compresses the second spring at the same time, so that the air in the pressure box 34 is transported to the air storage tank through the air outlet 343;

[0053] When the protrusion on one side of the second cam 31 moves away from the pressure plate 341, the encoder in the crushing motor 312 feeds back the rotation data of the second cam 31 to the control system. The control system controls the solenoid valve in the air inlet 342 to open and the solenoid valve in the air outlet 343 to close. The second spring is released, and the second spring pushes the pressure plate 341 to move outwards from the pressure box 34, so that the external air is drawn into the pressure box 34 through the air inlet 342;

[0054] As the protrusion on one side of the second cam 31 continues to rotate, more and more air is transported to the air storage tank, making the air pressure in the air storage tank gradually increase. The air storage tank stores this air, and the excess air is discharged through the air release valve.

[0055] As the second cam 31 continues to rotate, more and more powdered rock wool boards fall from the position between the extrusion plate 32 and the crushing box 3. The powdered rock wool boards land on the filter screen 33, and the control system simultaneously energizes and de-energizes the third spring 332 continuously; when the third spring 332 is energized, the overall length of the third spring 332 shortens, and the third spring 332 pulls the air blowing plate 331 to move from one end of the rectangular groove to the other end; after the third spring 332 is de-energized, it pushes the air blowing plate 331 to move in the reverse direction under its own elastic force; while the control system energizes and de-energizes the third spring 332, it opens the solenoid valve in the outlet pipeline of the air storage tank, so that the pressurized air in the air storage tank is transported through the pipeline to the air blowing plate 331, and is sprayed on the filter screen 33 through the air blowing holes on the air blowing plate 331, and then the filter screen 33 is brushed by the brush on the air blowing plate 331, making it difficult for the rock wool board to deposit on the filter screen 33, preventing the filter screen 33 from being blocked, and ensuring the normal filtering effect of the filter screen 33.

[0056] After being filtered, the rock wool board is conveyed downward to two groups of crushing wheels 351. The two groups of crushing wheels 351 further crush the powdered rock wool board, and the further crushed rock wool board passes through the screen 352 and is discharged from the discharge port.
