Description

Technical Field

[0001] The present invention relates to the technical field of target material crushing, and in particular to a metal target material recovery and crushing device and method thereof. Background Art

[0002] In semiconductor manufacturing, the electronics industry, and scientific research experiments, metal targets are indispensable consumables. With the end of their use cycle, a large amount of metal targets become waste. These metal targets often contain precious metals or rare metal elements. If they are discarded directly without treatment, it will cause a huge waste of resources and have adverse effects on the environment, making the recycling of metal targets very meaningful. Metal targets need to be crushed during the recycling process to facilitate subsequent processing, but there is currently no dedicated crushing device for targets. The hardness and toughness of different metal targets vary significantly. For example, titanium has higher hardness and toughness, requiring a slower crushing speed to avoid tool wear and overheating; aluminum is softer and can withstand higher speeds. At present, conventional crushing devices use a constant crushing speed for crushing, which will cause the crushing speed to be too fast when crushing target materials with higher hardness, resulting in overheating and wear; therefore, we propose a metal target recycling crushing device and method to solve this problem.

[0025] A feed opening is provided on the top of the crushing box, and a feed nozzle is fixedly installed in the feed opening.

[0026] The present invention also provides a metal target material recovery and crushing method, comprising the following steps:

[0027] S1: The control switch is closed, so that the drive motor is energized, the drive motor drives the drive shaft to rotate, the drive shaft drives the rotating frame to rotate synchronously, the rotating frame drives the worm to rotate through the sliding frame, the round rod, the arc-shaped connecting plate and the linkage frame, the worm drives the transmission shaft to rotate counterclockwise through the engagement with the worm wheel, the transmission shaft drives the installation shaft on the right to rotate counterclockwise through the transmission of the driving sprocket and the driven sprocket, and drives the installation shaft on the left to rotate clockwise through the engagement of the two transmission gears, thereby driving the two crushing rollers to rotate;

[0028] S2: Put the metal target into the feed nozzle and make it enter between the two crushing rollers. The two crushing rollers squeeze and crush the metal target while rotating. The crushing rollers will also cause the linkage frame to be subjected to rotational resistance, so that the linkage frame rotates relative to the rotating frame, and drives multiple sliding frames to move away from each other through the arc-shaped connecting plate. The sliding frame drives the vertical plate and the rotating drum to rotate and move to the left through the cooperation of the corresponding inclined rods and inclined holes. The rotating drum drives the connecting seat to move to the left through the cooperation with the two limit sleeves. The connecting seat drives the two conductive frames and the two insulating plates to move to the left. The insulating plate compresses the compression spring while moving until the rotational resistance of the compression spring bottom box rotating frame is exceeded. When the conductive frame moves, the length of the resistor bar connected to the drive motor circuit becomes larger and the resistance becomes larger, thereby reducing the speed of the drive motor to reduce the rotation speed of the drive shaft and the crushing roller, so that the crushing speed can be automatically lowered when crushing metal targets with higher hardness;

[0029] S3: The raw materials coarsely crushed by the crushing roller are introduced into the crushing barrel through the discharge circular pipe. The driving shaft rotates while driving the first bevel gear and the eccentric wheel to rotate synchronously. The first bevel gear drives the vertical shaft and the circular shaft to rotate by meshing with the second bevel gear and the third bevel gear. The circular shaft drives the conical dispersion disk to rotate while the circular shaft rotates, so that the raw materials dropped on the conical dispersion disk are thrown off to avoid accumulation. The vertical shaft rotates while driving the rotating column, the L rod and the crushing rod to rotate. The rotating column drives the rotating shaft to rotate synchronously through the cooperation of the cross groove and the cross plate. The rotating shaft drives the crushing knife to rotate, so as to finely crush the target material. While the eccentric wheel rotates, it drives the crushing barrel to move back and forth up and down through the cooperation of the connecting arm and the fixed shaft. The crushing barrel drives the screen to move back and forth up and down to screen the raw materials, so that the target material crushed to a sufficiently small particle size is screened out from the screen. At the same time, the screen drives the rotating shaft and the crushing knife to rotate up and down through the cooperation of the fixed barrel and the circular plate, thereby improving the crushing effect;

[0030] S4: When the crushing resistance of the crushing roller is too large during the crushing process, the insulating plate will press the stop button, thereby controlling the switch to be disconnected, thereby cutting off the power to the drive motor and stopping the crushing work in time to avoid damage to the drive motor;

[0031] S5. During the crushing process, the temperature of the crushed target material is monitored by a temperature sensor. When the temperature exceeds the set value, the controller controls the switch to disconnect, thereby avoiding overheating and damage to the target material.

[0032] Compared with the prior art, the present invention provides a metal target material recovery and crushing device and method thereof, which have the following beneficial effects:

[0033] (1) The driving motor drives the driving shaft to rotate, and the power transmission mechanism drives the crushing roller to rotate, so as to roughly crush the target material. At the same time, the first bevel gear, the third bevel gear, the eccentric wheel, the connecting arm, the rotating column and the cross plate drive the crushing knife to rotate and move up and down, so as to realize fine crushing of the target material. At the same time, the screen can be driven to vibrate up and down to realize automatic screening of the target material.

[0034] (2) The power transmission mechanism can automatically reduce the output speed of the drive motor when the crushing roller is subjected to increased pressure, thereby reducing the rotation speed of the crushing roller and the crushing knife, thereby ensuring the crushing effect when crushing targets with high hardness;

[0035] (3) The stop button can be set to stop the crushing in time when the crushing resistance is too large to avoid the device getting stuck;

[0036] (4) The temperature sensor and controller can monitor the crushing temperature in real time and stop the crushing in time when the temperature is too high to avoid damage to the target material. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] The present invention also provides a metal target material recovery and crushing method, comprising the following steps:

[0063] S1: The control switch 28 is closed, so that the drive motor 3 is energized, the drive motor 3 drives the drive shaft 302 to operate, the drive shaft 302 drives the rotating frame 17 to rotate synchronously, the rotating frame 17 drives the worm 308 to rotate through the sliding frame 16, the round rod 18, the arc-shaped connecting plate 19 and the linkage frame 20, the worm 308 drives the transmission shaft 305 to rotate counterclockwise through the engagement with the worm wheel 307, the transmission shaft 305 drives the right installation shaft 24 to rotate counterclockwise through the transmission of the driving sprocket 304 and the driven sprocket 303, and drives the left installation shaft 24 to rotate clockwise through the engagement of the two transmission gears 25, thereby driving the two crushing rollers 23 to rotate;

[0064] S2: Put the metal target into the feed nozzle 102 and make it enter between the two crushing rollers 23. The two crushing rollers 23 squeeze and crush the metal target while rotating. The crushing rollers 23 are subjected to rotation resistance, and the linkage frame 20 is subjected to rotation resistance, so that the linkage frame 20 rotates relative to the rotating frame 17, and drives the multiple slide frames 16 to move away from each other through the arc connecting plate 19. The slide frame 16 drives the vertical plate 14 and the rotating drum 6 to rotate and move to the left through the cooperation of the corresponding inclined rod 15 and the inclined hole. The rotating drum 6 is connected to the two limit sleeves. The cooperation of 13 drives the connecting seat 7 to move to the left, and the connecting seat 7 drives the two conductive frames 8 and the two insulating plates 9 to move to the left. The insulating plates 9 compress the compression spring 10 while moving, until the compression spring 10 bottom box rotating frame 17 is subjected to the rotation resistance. When the conductive frame 8 moves, the length of the resistor bar 11 connected to the circuit of the driving motor 3 becomes larger, and the resistance becomes larger, so that the rotation speed of the driving motor 3 is reduced to reduce the rotation speed of the driving shaft 302 and the crushing roller 23, so that the crushing speed can be automatically lowered when crushing metal targets with higher hardness;

[0065] S3: The raw materials roughly crushed by the crushing roller 23 are introduced into the crushing cylinder 2 through the discharge pipe. The driving shaft 302 rotates and drives the first bevel gear 411 and the eccentric wheel 26 to rotate synchronously. The first bevel gear 411 drives the vertical shaft 401 and the circular shaft 402 to rotate by meshing with the second bevel gear 412 and the third bevel gear 413. The rotation of the circular shaft 402 drives the conical dispersion disk 409 to rotate, so that the raw materials dropped on the conical dispersion disk 409 are thrown off to avoid accumulation. The rotation of the vertical shaft 401 drives the rotating column 403, the L rod 414 and the crushing rod 410 to rotate. The rotating column 403 rotates through the rotating column 403. The cross groove and the cross plate 404 cooperate to drive the rotating shaft 405 to rotate synchronously, and the rotating shaft 405 drives the crushing knife 406 to rotate, so as to finely crush the target material. While the eccentric wheel 26 rotates, it drives the crushing cylinder 2 to move up and down through the cooperation of the connecting arm 27 and the fixed shaft 201. The crushing cylinder 2 drives the screen 203 to move up and down to screen the raw materials, so that the target material crushed to a sufficiently small particle size is screened out from the screen 203. At the same time, the screen 203 drives the rotating shaft 405 and the crushing knife 406 to rotate up and down through the cooperation of the fixed cylinder 407 and the circular plate 408, thereby improving the crushing effect;

[0066] S4: When the crushing resistance of the crushing roller 23 is too large during the crushing process, the insulating plate 9 presses the stop button 22, thereby controlling the switch 28 to be disconnected, thereby cutting off the power supply of the drive motor 3 and stopping the crushing work in time to avoid damage to the drive motor 3;

[0067] S5. During the crushing process, the temperature of the crushed target material is monitored by the temperature sensor 204. When the temperature exceeds the set value, the controller 5 controls the switch 28 to be disconnected, thereby preventing the target material from being overheated and damaged.

[0068] In this embodiment, when in use, the driving motor 3 drives the driving shaft 302 to rotate, and the power transmission mechanism drives the crushing roller 23 to rotate, so as to roughly crush the target material. At the same time, the first bevel gear 411, the third bevel gear 413, the eccentric wheel 26, the connecting arm 27, the rotating column 403 and the cross plate 404 cooperate to drive the crushing knife to rotate and move up and down, so as to achieve fine crushing of the target material. At the same time, the screen 203 can be driven to vibrate up and down to achieve automatic screening of the target material; the power transmission mechanism can automatically reduce the output speed of the driving motor 3 when the crushing roller 23 is subjected to increased pressure, so as to reduce the rotation speed of the crushing roller 23 and the crushing knife 406, so as to ensure the crushing effect when crushing the target material with high hardness; the stop button 22 can stop the crushing in time when the crushing resistance is too large to avoid the device from getting stuck; the temperature sensor 204 and the controller 5 can monitor the crushing temperature in real time, and stop the crushing in time when the temperature is too high to avoid damage to the target material.

The two crushing rollers (23) squeeze and crush the metal target material while rotating. The crushing rollers (23) are subjected to rotational resistance and the linkage frame (20) is subjected to rotational resistance, so that the linkage frame (20) rotates relative to the rotating frame (17) and drives the plurality of slide frames (16) to move away from each other through the arc-shaped connecting plate (19). The slide frame (16) drives the vertical plate (14) and the rotating drum (6) to rotate and move to the left through the cooperation of the corresponding inclined rods (15) and the inclined holes.

The insulating plates (9) compress the compression spring (10) while moving, until the compression spring (10) is subjected to rotational resistance by the bottom box rotating frame (17). When the conductive frame (8) moves, the length of the resistor bar (11) connected to the circuit of the driving motor (3) increases, and the resistance increases, so that the rotation speed of the driving motor (3) is reduced to reduce the rotation speed of the driving shaft (302) and the crushing roller (23), so that the crushing speed can be automatically reduced when crushing a metal target with a higher hardness; S3: The raw materials coarsely crushed by the crushing roller (23) are introduced into the crushing drum (2) through the discharge tube.

While the eccentric wheel (26) rotates, it drives the crushing cylinder (2) to move back and forth up and down through the cooperation of the connecting arm (27) and the fixed shaft (201).

At the same time, the screen (203) drives the rotating shaft (405) and the crushing knife (406) to rotate and move up and down through the cooperation of the fixed cylinder (407) and the circular plate (408), thereby improving the crushing effect; S4: When the crushing resistance experienced by the crushing roller (23) is too great during the crushing process, the insulating plate (9) presses the stop button (22), thereby controlling the switch (28) to be disconnected, thereby disconnecting the drive motor (3), thereby stopping the crushing work in time and preventing damage to the drive motor (3); S5. During the pulverizing process, the temperature of the pulverized target material is monitored by a temperature sensor (204). When the temperature exceeds a set value, the switch (28) is controlled by a controller (5) to be disconnected, thereby preventing the target material from being overheated and damaged.
