Description

Technical Field

[0001] The invention relates to the technical field of waste lamp recycling, in particular to a material vibration unloading device. Background Art

[0002] Light tubes usually refer to straight tube fluorescent lamps, which are a very common lighting tool. Because they are so common, a huge amount of discarded light tubes are generated every year. The main materials of light tubes are glass and metal, both of which are recyclable materials. Therefore, in order to recycle them, there are many factories that recycle and process waste light tubes.

[0003] The lamp tube is a product of the combination of metal and glass. In the later processing process, in order to facilitate recycling, the glass and metal need to be separated from each other. Since metal and glass are both hard products, they cannot be separated by chemical methods and can only be separated by physical properties. Due to the high brittleness of glass, the glass is usually crushed to separate the glass from the metal.

[0004] A common method is to crush the glass and metal together and then remove the connected glass products from the metal bit by bit. This is not only time-consuming, but also the metal has high toughness and is easily deformed during the crushing process, and part of the glass is hidden in it, resulting in uneven screening. At the same time, since the glass and metal parts are tightly combined, it is difficult to separate them completely. Summary of the Invention

[0005] To this end, the technical problem to be solved by the present invention is to overcome the common method in the existing technology, which is to crush the glass and metal together, and then remove the connected glass products from the metal bit by bit. This is not only time-consuming, but also the metal has high toughness and is easily deformed during the crushing process, and part of the glass is hidden in it, resulting in uneven screening. At the same time, since the glass and metal parts are tightly combined, it is difficult to separate them completely.

[0006] In order to solve the above technical problems, the present invention provides a material vibration unloading device, including a vibration box, the interior of the vibration box is hollow, and the two sides of the vibration box are rotatably connected with a feed door and a discharge door respectively, the feed door is located above the discharge door, the inner side of the vibration box is provided with a screening plate and a crushing plate, the crushing plate is located above the screening plate, the feed door is located between the screening plate and the crushing plate, and the discharge door is located below the screening plate, and the outer side of the vibration box is provided with a shaking assembly, which is used to drive the vibration box to shake up and down, the inner side of the vibration box is fixedly connected to a reduction motor, the output end of the reduction motor is fixedly connected to a rotating rod, the outer side of the rotating rod is fixedly connected to the screening plate, and the bottom of the vibration box is open. Through this arrangement, the glass and metal of the waste lamps can be effectively physically separated without manual operation, with higher efficiency and higher safety.

[0007] In one embodiment of the present invention, the vibration assembly includes multiple electric cylinders, the output end of the electric cylinder is fixedly connected to a lifting rod, the outer side of the lifting rod is fixedly connected to the outer side of the vibration box, the bottom end of the electric cylinder is fixedly connected to a top seat, the outer side of the vibration box is fixedly connected to a support seat, and the bottom end of the support seat is fixedly connected to a telescopic rod. The lifting rod is driven by the electric cylinder to continuously perform lifting and lowering movements, thereby driving the vibration box as a whole to move up and down, causing the raw materials inside to collide up and down, and the setting of the telescopic rod makes the vibration process more uniform and provides a supporting effect at the same time.

[0008] In one embodiment of the present invention, a positioning frame is fixedly connected to the inner side of the vibration box, and the screening plate is located below the positioning frame. The opening area in the middle of the positioning frame is smaller than the area of ​​the screening plate. The positioning frame limits the upward tilt angle of the screening plate, so that the positioning frame can only rotate to a horizontal state at most. At the same time, it ensures that the screening plate provides support when it moves up and down, thereby reducing the impact of inertia on the screening plate.

[0009] In one embodiment of the present invention, a plurality of holes extending through to the bottom are provided on the top surface of the pulverizing disk, a plurality of electric telescopic rods are fixedly connected above the holes, and a sound wave generator is fixedly connected to the bottom output end of the electric telescopic rod. After shaking for a period of time, the electric telescopic rod is started to sink the sound wave generator downward, and the sound wave generator emits sound waves with the same frequency as the glass, thereby shattering the glass and breaking the places where the glass and metal are tightly bonded. Then, the shaking is continued to effectively separate the metal and the glass.

[0010] In one embodiment of the present invention, a plurality of impact blocks are fixedly connected to the bottom end of the pulverizing disk, and the impact blocks are arranged in a prism shape. A plurality of impact arms are arranged on the bottom surface of the pulverizing disk, and a driving assembly is arranged on the top of the impact arm. The driving assembly is used to drive the impact arm to move at a high frequency. Combined with the arrangement of the impact blocks, it can provide the effect of impact-breaking glass, and the high-frequency motion impact arm can break the glass into small fragments when the glass pieces hit it, so that they can fall smoothly from the screening disk, thereby improving the thoroughness of separation.

[0011] In one embodiment of the present invention, a crushing bar is fixedly connected to the outer surface of the impact arm, and the crushing bar is spirally coiled on the outside of the impact arm. The outer surface of the crushing bar is flat, and a plurality of protrusions are fixedly connected to the bottom surface of the impact arm. Combined with the arrangement of the crushing bar and the protrusions on the outside of the impact arm, the impact and crushing effect of the glass and the impact arm can be further increased, and the problem of incomplete crushing and large fragments sliding out of the discharge door along with the metal parts can be reduced.

[0012] In one embodiment of the present invention, the driving assembly includes a driving motor, which is fixedly connected to the shredding disk. The output end of the driving motor is fixedly connected to the impact arm. The impact arm is arranged in a truncated cone shape, and a counterweight block is fixedly connected to one side of the bottom of the impact arm. The impact arm is made of elastic material, thereby forming a high-frequency motion state, so that the glass that hits it is instantly shattered by the bumps and the crushing strips. After the rotation stops, the glass returns to its original position under the elastic material of the impact arm itself, and will not hinder the normal sinking of the sound wave generator.

[0013] In one embodiment of the present invention, a plurality of screening holes extending to the bottom are provided on the top surface of the screening disk, an inner clamping groove is provided on the inner side of the screening disk, an interlayer sheet is slidably connected in the inner clamping groove, and screening holes arranged in the same manner as the surface of the screening disk are also provided on the top surface of the interlayer sheet, and a moving component is provided on the outer side of the interlayer sheet, and the moving component is used to drive the interlayer sheet to move. Through this arrangement, the equipment can adapt to a variety of raw materials, and the screening size is set to the minimum scale of the metal parts to ensure that the metal parts will not fall from the screening disk, thereby improving the applicability of the equipment.

[0014] In one embodiment of the present invention, the moving assembly includes a plurality of springs, both ends of the springs are respectively fixed between the interlayer sheet and the screening disk, the rotating rod includes an inner rod and an outer rod, the inner rod is fixed to the reduction motor, the outer rod is rotatably connected to the inner side of the vibration box, an open groove is provided in the middle part of the outer side of the outer rod, a flexible pull strip is fixed between the interlayer sheet and the inner rod, the outer side of the inner rod and the inner side of the outer rod are both rough-shaped. Through this arrangement, there is no need to set up other power parts, and only one reduction motor is needed to achieve the effect of controlling the opening and closing rotation of the screening disk and adjusting the interlayer sheet.

[0015] In one embodiment of the present invention, a locking block is fixedly connected to the middle of one end of the screening plate away from the reduction motor, a locking hole is provided at the top of the locking block and extends to the bottom, a lower plug rod is fixedly connected to the end of the bottom of the positioning frame corresponding to the locking block, and a receiving groove is provided on both sides of the lower plug rod, and a rotating shaft is rotatably connected to the bottom of the outer side of the receiving groove, and an expansion arm is fixedly connected to the outer side of the rotating shaft, and a torsion spring is fixedly connected between the rotating shaft and the receiving groove, and when the screening plate is rotated to the horizontal, the lower plug rod will be inserted into the locking block, and then when the vibration box is shaken up and down, the expansion arm will continue to open and close, but there is a screening plate above the interlayer sheet to block it, so when the screen plate is moved up and down, the expansion arm will continue to open and close. When shaking, under the action of inertia, the screening disc sometimes tends to rotate downward, and the screening disc with a downward trend will support the unfolded interlayer sheet. Due to the friction after supporting, the interlayer sheet will not retract but remain in the unfolded state, thereby supporting the column screening disc. When the shaking stops, all the forces disappear, and the unfolding arm will return to the storage slot under the action of the torsion spring, allowing the screening disc to rotate downward normally. Through this setting, not only the self-locking function is achieved, but also it is ensured that the screening disc will not rotate downward under the action of inertia under the effect of vibration, without the need for an electric valve to block it, and the supporting force will not be transmitted to the reduction motor, thereby improving the service life of the reduction motor.

[0016] The above technical solution of the present invention has the following advantages over the prior art:

[0017] The material vibration unloading device described in the present invention feeds the waste lamp raw materials into the space between the crushing disk and the screening disk through the feeding door through the arrangement of the screening disk and the crushing disk. The up and down shaking of the shaking assembly can drive the vibration box to shake up and down as a whole, so that the raw materials inside collide with the bottom surface of the crushing disk, so that the more brittle glass is broken in the collision, while the metal has strong toughness and will not be broken in the collision. The broken glass becomes small particles and falls through the screening disk. After a period of time, the discharge door is opened, and the reduction motor drives the rotating rod and the screening disk to rotate downward, allowing the remaining metal materials to leak out through the discharge door. Through this arrangement, the glass and metal of the waste lamps are effectively physically separated, without the need for manual operation, and with higher efficiency and higher safety.

[0018] The electric cylinder drives the lifting rod to continuously move up and down, thereby driving the vibration box to move up and down as a whole, causing the raw materials inside to collide up and down. The setting of the telescopic rod makes the vibration process more uniform and provides a supporting effect at the same time.

[0019] Combined with the setting of the impact block, it can provide the effect of impact-breaking glass, and the high-frequency motion impact arm can break the glass into small fragments when the glass pieces hit it, so that they can fall smoothly from the screening plate, thereby improving the thoroughness of separation.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0032] Reference Figures 1 to 9As shown, a material vibration unloading device of the present invention includes a vibration box 1, the interior of the vibration box 1 is hollow, and the two sides of the vibration box 1 are rotatably connected with the feed door 4 and the discharge door 2, the feed door 4 is located above the discharge door 2, the inner side of the vibration box 1 is provided with a screening plate 9 and a crushing plate 6, the crushing plate 6 is located above the screening plate 9, the feed door 4 is located between the screening plate 9 and the crushing plate 6, and the discharge door 2 is located below the screening plate 9. A shaking component is provided on the outer side of the vibration box 1, and the shaking component is used to drive the vibration box 1 to shake up and down, the inner side of the vibration box 1 is fixedly connected with a reduction motor 18, the output end of the reduction motor 18 is fixedly connected with a rotating rod 19, the outer side of the rotating rod 19 is fixedly connected to the screening plate 9, and the bottom of the vibration box 1 is open. When working, the common way is to crush glass and metal together, and then remove the connected glass products from the metal bit by bit, which is not only time-consuming, but also has high metal toughness and is easy to crush. The glass is then crushed and the screen disc 9 is moved back and forth, and the crushing plate 6 is moved back and forth, so that the glass is not easily crushed.

[0033] The vibration assembly includes multiple electric cylinders 13, the output end of the electric cylinder 13 is fixedly connected to the lifting rod 5, the outer side of the lifting rod 5 is fixedly connected to the outer side of the vibration box 1, the bottom end of the electric cylinder 13 is fixedly connected to the top seat 12, the outer side of the vibration box 1 is fixedly connected to the support seat 3, and the bottom end of the support seat 3 is fixedly connected to the telescopic rod 11. During operation, the electric cylinder 13 drives the lifting rod 5 to continuously perform lifting and lowering movements, thereby driving the vibration box 1 as a whole to move up and down, allowing the raw materials inside to collide up and down, and the setting of the telescopic rod 11 makes the vibration process more uniform and provides a supporting effect at the same time.

[0034] A positioning frame 10 is fixedly connected to the inner side of the vibration box 1, and the screening plate 9 is located below the positioning frame 10. The opening area in the middle of the positioning frame 10 is smaller than the area of ​​the screening plate 9. When working, the positioning frame 10 limits the upward angle of the screening plate 9, so that the positioning frame 10 can only rotate to a horizontal state at most, while ensuring that the screening plate 9 provides support when moving up and down, reducing the impact of inertia on the screening plate 9.

[0035] A plurality of holes extending to the bottom are provided on the top surface of the crushing disk 6, and a plurality of electric telescopic rods 7 are fixedly connected above the holes. The bottom output end of the electric telescopic rod 7 is fixedly connected to the sound wave generator 26. When in operation, after shaking for a period of time, the electric telescopic rod 7 is started to sink the sound wave generator 26 downward, and the sound wave generator 26 emits sound waves with the same frequency as the glass, thereby shattering the glass and breaking the places where the glass and metal are tightly bonded. Then, the shaking is continued to effectively separate the metal and the glass.

[0036] A plurality of impact blocks 14 are fixedly connected to the bottom end of the pulverizing disk 6, and the impact blocks 14 are arranged in a prism shape. A plurality of impact arms 8 are arranged on the bottom surface of the pulverizing disk 6, and a driving assembly is arranged on the top of the impact arm 8. The driving assembly is used to drive the impact arm 8 to move at a high frequency. When working, in conjunction with the setting of the impact block 14, the effect of impact-breaking glass can be provided, and the high-frequency motion impact arm 8 can break the glass into small fragments when the glass pieces hit it, so that they can fall smoothly from the screening disk 9, thereby improving the thoroughness of separation.

[0037] The outer surface of the impact arm 8 is fixedly connected to a crushing bar 15, which is spirally coiled on the outside of the impact arm 8. The outer surface of the crushing bar 15 is flat, and the bottom surface of the impact arm 8 is fixedly connected to a plurality of protrusions 17. When working, the crushing bar 15 and the protrusions 17 on the outside of the impact arm 8 can further increase the impact and crushing effect of the glass and the impact arm 8, and reduce the problem of incomplete crushing and large fragments sliding out of the discharge door 2 along with the metal parts.

[0038] The driving assembly includes a driving motor 16, which is fixedly connected to the shredding disk 6. The output end of the driving motor 16 is fixedly connected to the impact arm 8. The impact arm 8 is arranged in a truncated cone shape, and a counterweight is fixedly connected to one side of the bottom of the impact arm 8. The impact arm 8 is made of elastic material. During operation, as the driving motor 16 rotates and the counterweight is set, the impact arm 8 bends itself due to the center of gravity being biased to one side during rotation, thereby forming a high-frequency motion state, so that the glass that hits it is instantly shattered by the protrusion 17 and the crushing bar 15. After the rotation stops, the impact arm 8 returns to its original position under the elastic material of the impact arm 8 itself, and will not hinder the normal sinking of the sound wave generator 26.

[0039] A plurality of screening holes extending to the bottom are provided on the top surface of the screening plate 9, an inner clamping groove is provided on the inner side of the screening plate 9, an interlayer sheet 25 is slidably connected in the inner clamping groove, and screening holes arranged in the same manner as the surface of the screening plate 9 are also provided on the top surface of the interlayer sheet 25, and a moving component is provided on the outer side of the interlayer sheet 25, and the moving component is used to drive the interlayer sheet 25 to move. During operation, the interlayer sheet 25 is driven to move by the moving component, so that the screening holes of the two screening plates 9 and the interlayer sheet 25 partially intersect, and the screening width can be controlled. Through this setting, the equipment can adapt to a variety of raw materials, and the screening size is set to the minimum scale of the metal parts to ensure that the metal parts will not fall from the screening plate 9; because there are some small metal parts in the lamp tube, in order to fully separate the glass and metal parts, an adjustable screening space is provided, thereby improving the applicability of the equipment.

[0040] The moving assembly includes a plurality of springs 22, the two ends of the springs 22 are respectively fixed between the interlayer sheet 25 and the screening plate 9, the rotating rod 19 includes an inner rod and an outer rod, the inner rod is fixed to the reduction motor 18, the outer rod is rotatably connected to the inner side of the vibration box 1, an open groove is provided in the middle of the outer side of the outer rod, a flexible pulling strip 20 is fixed between the interlayer sheet 25 and the inner rod, the outer side of the inner rod and the inner side of the outer rod are both rough-shaped. When working, when the interlayer sheet 25 needs to be adjusted, the screening plate 9 is driven to rotate horizontally and squeeze the positioning frame through the reduction motor 18 10, continue to let the reduction motor 18 rotate. Since the inner rod and the outer rod are rotatably connected, the reduction motor 18 has a huge force that can overcome the friction and allow the inner rod to rotate by itself, thereby winding up the pulling strip 20, thereby driving the interlayer sheet 25 to move. When the metal part is sent out, it rotates downward to the screening plate 9 to a vertical state, and continues to rotate the rotating rod 19 to reset the inner rod. Under the action of the spring 22, the interlayer sheet 25 will return to its place. Through this setting, there is no need to set up other power parts. Only one reduction motor 18 is needed to achieve the effect of controlling the opening and closing rotation of the screening plate 9 and adjusting the interlayer sheet 25.

[0041] The middle part of the end of the screening disc 9 away from the reduction motor 18 is fixed with a locking block 21, and the top of the locking block 21 is provided with a locking hole that runs through to the bottom. The bottom end of the positioning frame 10 and the end corresponding to the locking block 21 are fixed with a lower plug rod 23, and both sides of the lower plug rod 23 are provided with a receiving groove. The outer bottom of the receiving groove is rotatably connected with a rotating shaft, and the outer side of the rotating shaft is fixed with an expansion arm 24, and a torsion spring is fixed between the rotating shaft and the receiving groove. During operation, when the screening disc 9 is rotated to the horizontal, the lower plug rod 23 will be inserted into the locking block 21, and then when the vibration box 1 is shaken up and down, the expansion arm 24 will continue to open and close, but there is a screening disc 9 above the interlayer sheet 25 to block it. When shaking up and down, under the action of inertia, the screening disc 9 sometimes tends to rotate downward, and the screening disc 9 with a downward trend will support the unfolded interlayer sheet 25. Since there is friction after supporting, the interlayer sheet 25 will not retract but will remain in the unfolded state, thereby supporting the column screening disc 9. When the shaking stops, all forces disappear, and the unfolding arm 24 will return to the storage slot under the action of the torsion spring, allowing the screening disc 9 to rotate downward normally. Through this setting, not only the self-locking function is achieved, but also it is ensured that the screening disc 9 will not rotate downward under the action of inertia under the effect of vibration, and no electric valve is needed to block it, and the supporting force will not be transmitted to the reduction motor 18, thereby improving the service life of the reduction motor 18.

[0042] During operation, a common method is to crush the glass and metal together, and then remove the connected glass products from the metal bit by bit. This is not only time-consuming, but also the metal has high toughness and is easily deformed during the crushing process, and part of the glass is hidden in it, resulting in uneven screening. At the same time, since the glass and metal parts are tightly combined, it is difficult to separate them completely. Through the setting of the screening plate 9 and the crushing plate 6, the raw materials are fed into the space between the crushing plate 6 and the screening plate 9 through the feed door 4. By shaking the assembly up and down, the vibration box 1 can be driven to shake up and down as a whole, so that the raw materials inside collide with the bottom surface of the crushing plate 6, so that the more brittle glass is broken in the collision, while the metal has strong toughness and will not be broken in the collision. The broken glass becomes small particles and falls through the screening plate 9. After a period of time, the discharge door 2 is opened, and the reduction motor 18 drives the rotating rod 19 and the screening plate 9 to rotate downward, allowing the remaining metal materials to leak out through the discharge door 2. Through this arrangement, the glass and metal of the waste lamp tubes are effectively physically separated, without the need for manual operation, with higher efficiency and higher safety. The electric cylinder 13 drives the lifting rod 5 to continuously move up and down, thereby driving the vibration box 1 as a whole to move up and down, allowing the raw materials inside to collide up and down, and the setting of the telescopic rod 11 makes the vibration process more uniform while providing a supporting effect. The positioning frame 10 limits the upward tilt angle of the screening plate 9, so that the positioning frame 10 can only rotate to a horizontal state at most, while ensuring that the screening plate 9 provides support when it moves up and down, reducing the influence of inertia on the screening plate 9. After shaking for a period of time, the electric telescopic rod 7 is started to sink the sound wave generator 26, and the sound wave generator 26 emits sound waves with the same frequency as the glass, which can shatter the glass and break the places where the glass and metal are tightly combined. Then, the shaking is continued to effectively separate the metal and the glass. In conjunction with the setting of the impact block 14, the effect of impact-breaking glass can be provided, and the high-frequency motion of the impact arm 8 can break the glass into small fragments when the glass pieces hit it, so that they can fall smoothly from the screening plate 9, thereby improving the degree of separation. In conjunction with the setting of the breaking strip 15 and the protrusion 17 on the outside of the impact arm 8, the impact and crushing effect of the glass and the impact arm 8 can be further increased, and the incomplete crushing can be reduced, and large fragments will follow the metal pieces. The problem of the glass sliding out of the discharge door 2 is solved; as the driving motor 16 rotates and the counterweight is set, the impact arm 8 bends itself due to the center of gravity being biased to one side during rotation, thereby forming a high-frequency motion state, so that the glass that hits it is instantly broken by the protrusion 17 and the crushing bar 15, and after the rotation stops, the impact arm 8 returns to its original position under the elastic material of the impact arm 8 itself, and does not hinder the normal sinking of the sound wave generator 26; the interlayer sheet 25 is driven to move by the moving component, so that the screening holes of the two screening discs 9 and the interlayer sheet 25 are partially crossed, and the screening width can be controlled. Through this setting, the equipment can adapt to a variety of raw materials, and the screening size is set to the minimum size of the metal parts to ensure that the metal parts will not fall from the screening disc 9, thereby improving the applicability of the equipment;When the sandwich sheet 25 needs to be adjusted, the screening plate 9 is driven by the reduction motor 18 to rotate horizontally and squeeze the positioning frame 10, and the reduction motor 18 is continued to rotate. Since the inner rod and the outer rod are rotationally connected, the reduction motor 18 has a huge force that can overcome the friction and make the inner rod rotate by itself, thereby winding the pulling strip 20, thereby driving the sandwich sheet 25 to move. When the metal part is sent out, it is rotated downward to the screening plate 9 to a vertical state, and the rotating rod 19 is continued to be rotated to reset the inner rod. Under the action of the spring 22, the sandwich sheet 25 will return to its original position. Through this arrangement, there is no need to set up other power parts. Only a reduction motor 18 is required to achieve the effect of controlling the opening and closing rotation of the screening plate 9 and adjusting the sandwich sheet 25; when the screening plate 9 is rotated to the horizontal, the lower plug-in rod 23 will be inserted into the locking block 21, and then the vibration box 1 is opened. When the swaying mechanism is shaken up and down, the deployment arm 24 will continuously open and close. However, the screening disc 9 above the sandwich plate 25 blocks the movement. Therefore, when the swaying mechanism is shaken up and down, the screening disc 9 sometimes tends to rotate downward due to inertia. The screening disc 9 with the tendency to move downward will press against the deployed sandwich plate 25. Due to the friction generated by the pressure, the sandwich plate 25 will not retract but will remain in the deployed state, thereby supporting the screening disc 9. When the swaying mechanism stops, all forces disappear, and the deployment arm 24 will return to the storage slot under the action of the torsion spring, allowing the screening disc 9 to rotate downward normally. This arrangement not only realizes the self-locking function, but also ensures that the screening disc 9 will not rotate downward due to inertia under the effect of vibration, without the need for an electric valve to block it, and the supporting force will not be transmitted to the reduction motor 18, thereby improving the service life of the reduction motor 18.
