Description

Technical Field

[0001] The invention relates to the technical field of circuit board recycling, in particular to a device for recycling and processing waste PCB circuit boards. Background Art

[0002] With the widespread use of electronic products, electronic waste is also growing. Electronic waste contains a large amount of precious metals such as copper, cobalt, nickel, gold, and silver. If electronic waste is not handled properly, it will pollute the environment. If handled well, a large amount of rare metals can be recycled, thus turning waste into treasure.

[0003] Nowadays, PCB circuit boards have gradually become mainstream. When recycling them, they need to go through the following steps: crushing, air separation, chemical treatment and electrostatic separation. Among them, the crushing process is divided into three steps: shredding process, coarse crushing process and crushing process. The materials that have completed the crushing process are subjected to air separation, and then chemical treatment and electrostatic separation are used to separate the metal materials and non-metallic materials in the circuit board.

[0004] The crushing stage of PCB circuit boards is particularly important in the recycling process. For example, a Chinese patent with application number 202410449502.6 discloses a waste PCB circuit board recycling device, including a crushing device, a feeding device and an external frame, and the crushing device is arranged inside the external frame.

[0005] The technical solution in the above patent document realizes the combination of the shredding process and the coarse crushing process, but the PCB circuit board still needs to be crushed during the recycling process, otherwise it will affect the subsequent sorting and processing effect, and the comprehensiveness of the recycling of the PCB circuit board cannot be guaranteed, which is easy to cause waste of resources; because the crushing process adopts batch processing when processing the material, and the processed material in the above technical solution is discharged continuously, in order to ensure the comprehensiveness of the material crushing process, it is necessary to set up a material temporary storage structure and related transportation equipment, so as to realize the batch transportation of the material to the crushing process. This method will not only increase the manufacturing cost of the equipment during actual use, but also need to intermittently wait for the current material to complete the crushing process during the recycling process of the PCB circuit board, and unload the material before it can be put into the material again, which consumes time and affects the efficiency of the recycling of the PCB circuit board.

A support column 222122 is fixedly connected to the bottom shell wall of the collar 222121, and a ball is rollingly connected to the bottom end of the support column 222122. The fixed setting of the collar 222121 on the air guide tube 22210 can ensure the stability of the lifting movement of the air guide tube 22210 and the timely reset after the rotation adjustment.

[0069] See also Figure 7-Figure 8In the embodiment of the present invention, an air guide channel 22216 for air guide is provided inside the columnar platform 2221. The air guide channel 22216 is composed of an annular cavity, an oblique air guide cavity and an air jet cavity. Among them, the oblique air guide cavity and the air jet cavity each include a plurality. The plurality of air jet cavities are arranged on the outer shell wall of the annular cavity along the circumferential direction, and the air outlet end of the air jet cavity penetrates the outer circumferential wall of the sleeve 2222. The plurality of oblique air guide cavities are arranged on the inner shell wall of the annular cavity along the circumferential direction, and the air inlet end of the oblique air guide cavity penetrates the outer circumferential wall of the sleeve 2222, and is communicated with the inner cavity of the air guide tube 22210 through the notch. When the air guide tube 22210 moves upward, the notch thereon is misaligned with the oblique air guide cavity in the air guide channel 22216, thereby preventing wind from entering the air guide channel 22216. When the air guide tube 22210 moves downward, the notch thereon is connected with the oblique air guide cavity in the air guide channel 22216, thereby the gas in the air guide tube 22210 enters the air guide channel 22216, thereby blowing the processed material on the grinding disc 221 to accelerate its unloading speed. Since the jet cavity adopts an inclined design and the wind force entering it is small, the gas discharged therefrom moves obliquely downward, thereby preventing the material from splashing inside the processing cylinder 21.

[0070] See also Figure 3-Figure 4 In the embodiment of the present invention, a slide groove is provided on the top outer wall of the top cover 212, a slider is slidably connected in the slide groove, a wedge plate 22217 is fixedly connected to the top of the slider, and the wedge plate 22217 is set in a single-sided inclined manner. A connecting plate 22218 is connected to the inner wall of the wedge plate 22217 by screws, and a rack 22219 is fixedly connected to the end of the connecting plate 22218 away from the wedge plate 22217. The rack 22219 is meshed with the corresponding driven gear ring 22213 for transmission, and the inclined surface of the wedge plate 22217 is in active contact with the corresponding ball bearing. When the wedge plate 22217 contacts the ball bearing on the support column 222122, as the wedge plate 22217 moves, the support column 222122 moves down along its inclined surface, and then the guide column 22210 moves down under the action of gravity, thereby causing the blocking member 22211 to move down, thereby canceling the blocking of the discharge hole group. When the wedge plate 22217 leaves the supporting column 222122, the rack 22219 just contacts the driven gear ring 22213, thereby driving the guide column 22210 to rotate, thereby realizing the staggered setting of the sealing piece 22211 on the bottom end thereof, and facilitating the unloading of materials.

[0071] See also Figure 1 , Figure 4 and Fig.11In the embodiment of the present invention, the driving member includes a motor 53 disposed on the outer wall of the top of the carrier 1. A rotating shaft 54 ​​is installed at the output end of the motor 53, a cam 55 is sleeved on the rotating shaft 54, and the top end of the rotating shaft 54 ​​is mounted on the rotating shaft through a coupling. The movement of the motor 53 causes the rotating shaft 54 ​​to move, thereby synchronously driving the cam 55 and the rotating shaft to move.

[0072] The swinging member includes a U-shaped plate 51, and both ends of the U-shaped plate 51 are respectively fixedly connected to the corresponding wedge-shaped plate 22217 by bolts. A frame 52 for fitting a cam 55 is welded on the side wall of the U-shaped plate 51. The movement of the cam 55 causes the frame 52 to drive the U-shaped plate 51 to move horizontally, thereby realizing the drive adjustment of the corresponding wedge-shaped plate 22217.

[0073] See also Figure 2 and Fig.12 In the embodiment of the present invention, the vibration assembly includes a circular hole opened on the top plate 73, and a knocking rod 74 is movably connected in the circular hole. A rubber sleeve is provided at the bottom end of the knocking rod 74 for knocking the ramp plate 72. The provision of the rubber sleeve prevents the knocking rod 74 from causing deformation of the ramp plate 72 when vibrating the ramp plate 72.

[0074] The peripheral wall of the knocking rod 74 is sleeved with a baffle, a return spring and a flip plate 75. The baffle and the flip plate 75 are both fixedly connected to the outer peripheral wall of the knocking rod 74, and the flip plate 75 is located inside the water tank 71, and the baffle is located above the ramp plate 72. The top end of the return spring is fixedly connected to the baffle, and the bottom end of the return spring is arranged on the top plate 73. The arrangement of the flip plate 75 enables the knocking rod 74 to synchronously drive the water resources in the water tank 71 to flip when it moves, thereby improving the full contact between the materials and the water resources in the water tank 71, and the arrangement of the return spring enables the knocking rod 74 to produce a strong vibration effect, so as to achieve the accumulation of the settled materials on one side of the ramp plate 72.

[0075] The top of the knocking rod 74 is fixedly connected with a double-sided wedge 76, and a curved rod 77 is provided on the side of the double-sided wedge 76. One end of the curved rod 77 is fixedly connected to the driving mechanism 5 by bolts, and the other end of the curved rod 77 is rollingly connected with a movable ball, and the movable ball is in rolling contact with the inclined surface of the double-sided wedge 76. The vertical section of the double-sided wedge 76 is an L-shaped structure, one end of which is fixedly connected to the top of the knocking rod 74, and the two sides of the other end are provided with inclined surfaces, so that when the driving mechanism 5 moves, the curved rod 77 is in compression contact with the double-sided wedge 76 during the lateral movement, and then cooperates with the reset spring to achieve the vibration effect of the knocking rod 74.

[0076] The working principle of the present invention is as follows: when the equipment is used, the material processed by the coarse crushing process is transported from the material conveying main pipe 4 to the collecting barrel 31 in the material control mechanism 3. At this time, the state of the special-shaped disc 32 in the collecting barrel 31 allows the material entering the collecting barrel 31 to enter the corresponding diverting pipe 33 through the hole, and then the corresponding diverting pipe 33 transports the material to the fine crushing mechanism in the corresponding processing component 2.

[0077] When the material enters the processing cylinder 21, at this time, the motor 2229 in the grinding assembly 222 in the crushing mechanism 22 of the current fine crushing mechanism is running, driving the driving gear 2228 to rotate. Due to the meshing transmission between the driving gear 2228 and the outer gear ring 2227, the sleeve 2222 is driven to rotate synchronously. During the rotation process, the sleeve 2222 drives the rolling element 2224 to perform circular motion through the splicing column 2223, and the scraper 2225 arranged on the sleeve 2222 also moves synchronously. During the movement process, the scraper 2225 first scrapes and spreads the material entering the grinding disc 221, and then the rolling element 2224 rolls the spread material during the circular motion, and the rolling element 2224 itself also performs rotational motion while the circular motion is in progress, thereby further realizing efficient rolling and crushing of the material on the grinding disc 221.

[0078] The material released by the diverter pipe 33 onto the grinding disc 221 is a thin stream of material, and the continuous movement of the grinding assembly 222 in the pulverizing mechanism 22 can ensure efficient pulverization of the material. If the current processing cylinder 21 reaches the upper limit of the material processing, the drive mechanism 5 is turned on to switch the two processing components 2, and the other processing component 2 continuously processes the material, while the processing cylinder 21 unloads the processed material, thereby ensuring the continuity of material processing.

[0079] When the driving mechanism 5 is in operation, the motor 1 53 drives the rotating shaft 54 ​​to move, and the rotating shaft 54 ​​realizes the movement of the cam 55 and the rotating shaft synchronously during the movement. The movement of the rotating shaft adjusts the special-shaped disc 32 in the material control mechanism 3, and the movement of the cam 55 drives the U-shaped plate 51 to move horizontally through the frame 52. When the U-shaped plate 51 moves, the wedge plates 22217 connected at both ends thereof move accordingly. The wedge plate 22217 in the processing component 2 that has completed the material processing moves backward with the movement of the U-shaped plate 51, and at this time, the rack 22219 is driven to move synchronously through the connecting plate 22218. When the wedge plate 22217 moves, when the ball on the support column 222122 in the movable part 22212 in the current grinding assembly 222 moves in contact with the inclined surface of the corresponding wedge plate 22217, the air guide tube 22210 moves downward under the action of gravity as the wedge plate 22217 moves. When the movable part 22212 is separated from the wedge plate 22217, the continuous movement of the wedge plate 22217 will drive the rack 22219 through the connecting plate 22218 to achieve meshing adjustment with the corresponding driven gear ring 22213, thereby realizing the rotation adjustment of the air guide tube 22210.

[0080] During the downward movement of the air guide tube 22210, the blocking member 22211 at the bottom thereof moves downward, and the blocking member 22211 cancels the blocking of the discharge hole group on the grinding disc 221, so that the processed materials on the grinding disc 221 are discharged from the discharge hole group. The subsequent rotation of the air guide tube 22210 realizes the rotation of the blocking member 22211, so as to prevent the blocking member 22211 from obstructing the discharged materials.

[0081] During the movement of the wedge plate 22217 in the other processing component 2, the connecting plate 22218 drives the rack 22219 to move, and the rack 22219 first contacts the corresponding driven gear ring 22213, and then the air guide tube 22210 is first rotated and adjusted. The corresponding blocking member 22211 corresponds to the discharge hole group on the current grinding disc 221 after adjustment, and then, the continuous movement of the current wedge plate 22217 makes the wedge plate 22217 contact the support column 222122 of the movable member 22212 in the grinding assembly 222, thereby driving the blocking member 22211 to move upward through the air guide tube 22210, so as to achieve the blocking of the discharge hole group on the grinding disc 221 in the grinding assembly 222, and facilitate the processing of the materials dropped in the automatic material control mechanism 3. The second motor 53 drives the rotating shaft 54 ​​to move half a circle, which not only realizes the switching of the flow direction of the passing material by the special-shaped disk 32, but also realizes the switching process between the two processing components 2. After the switching is completed, the grinding component 222 in the new processing component 2 repeats the above steps.

[0082] The materials discharged from the grinding assembly 222 are collected by the corresponding collecting hopper 23 and then enter the shell cover 24 in the air separation mechanism. After the materials enter the shell cover 24, the non-metallic materials or materials containing a small amount of metal materials enter the water tank 71 of the temporary storage assembly in the flotation mechanism 7 through the discharge air duct 25 under the action of the wind blown by the strip fan body 27. The materials entering the water tank 71 come into contact with the water resources in the water tank 71, and then the materials containing metal materials sink to the ramp plate 72, and the non-metallic materials float on the water surface.

[0083] The metal materials after air separation directly fall into the collection box 6 for collection. When the driving mechanism 5 is in operation, the movement of the swinging member synchronously drives the bending rod 77 of the vibration assembly in the flotation mechanism 7 to move. The bending rod 77 contacts the double-sided wedge block 76 during the displacement process, so that the knocking rod 74 is forced to move upward, stretching the reset spring, and the knocking rod 74 drives the flip plate 75 to move when it moves upward. When the bending rod 77 is out of contact with the double-sided wedge block 76, the knocking rod 74 is reset under the action of the reset spring, and then not only knocks the ramp plate 72, so that the settled materials are accumulated on one side, but also the flip plate 75 drives the water resources in the water tank 71 to flip, so that the materials floating on the water surface are fully in contact with the water resources to avoid omission.

[0084] When the air guide pipe 22210 moves downward, the notch thereon communicates with the air guide channel 22216 opened inside the columnar platform 2221 , and the wind diverted by the guide pipe is discharged from the jet cavity of the air guide channel 22216 , further accelerating the unloading speed of the processed material on the grinding disc 221 .

[0085] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
