Description

Technical Field

[0001] The invention relates to the technical field of waste electric meter processing, and in particular to a waste electric meter crushing and sorting processing device. Background Art

[0002] Scrapped meters refer to electric energy meters that can no longer be used normally due to various reasons. Complete scrapped meters are large in size and take up a lot of space. By breaking them, the meters can be broken into smaller pieces, which greatly reduces their size. In this way, when transporting scrapped meters to the processing site, more materials can be loaded in the same transportation tool, reducing the transportation cost per unit of materials. At the same time, in the storage link, the broken meter fragments also take up less warehouse space than the complete meters, which helps to improve the space utilization of the warehouse.

This method can only achieve preliminary material crushing, and it is difficult to carry out fine processing of the crushed materials. The uneven particle size of the crushed materials makes subsequent separation and screening difficult.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example: Please see attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a scrapped electric meter crushing and sorting processing device, including a body 1, the body 1 serves as a supporting frame of the entire device and provides an installation foundation for each internal component. A motor 3 is fixedly connected to one side of the body 1. The motor 3, as a power source, can provide a stable and continuous driving force for a series of subsequent crushing, sorting and other operations. Two crushing rollers 4 are rotatably connected to the top of the body 1. The two crushing rollers 4 cooperate with each other to perform preliminary crushing processing on the scrapped electric meter put in, and crush the outer shell of the electric meter and the larger internal components. A first circular gear 5 is fixedly connected to the side of the crushing roller 4 away from the motor 3. The output end of the motor 3 is connected to one of the crushing rollers 4, so that the power generated by the motor 3 can be accurately transmitted to the crushing roller 4. The crushing process is started, the two first circular gears 5 are meshed, and power transmission and coordinated operation are realized through the gear structure, ensuring that the two crushing rollers 4 rotate synchronously and in opposite directions to enhance the crushing effect. The body 1 is provided with a rolling component, a separation component and a screening component from top to bottom. The rolling component can further refine the crushed material, the separation component is used to sort recyclable materials such as metals, and the screening component separates materials of different particle sizes to achieve the purpose of efficient recycling. The outer wall of the body 1 is provided with a transmission component and a reciprocating component. The transmission component is responsible for transmitting the power distribution at the crushing roller 4 to other components to ensure the linkage operation of the entire device, and the reciprocating component provides a specific motion mode for the screening process to improve the screening accuracy and efficiency; The rolling assembly includes a rotating shaft 11, a rolling box 6 and a fixed plate 7. The rotating shaft 11 is rotatably connected to the inner wall of the body 1. The rotation of the rotating shaft 11 drives the subsequent second bevel gear 12 to rotate. The second bevel gear 12 is fixedly connected to the rotating shaft 11. The second bevel gear 12 is used to change the rotation direction of the rotating shaft 11 so that it can receive power from the crushing roller 4 later. The fixed plate 7 is fixedly connected to the inside of the body 1. The fixed plate 7 provides an installation environment for subsequent components. The top of the fixed plate 7 is rotatably connected to the first bevel gear 8. The first bevel gear 8 is meshed with the second bevel gear 12 to accurately change the power transmission path and convert the horizontal rotation into a vertical rotation suitable for rolling. The top of the first bevel gear 8 is fixedly connected to a rotating block 20. The rotating block 20 It rotates along with the first bevel gear 8, providing a rotation basis for the subsequent first eccentric shaft 9 and the rolling roller 10. The top edge of the rotating block 20 is fixedly connected to the first eccentric shaft 9. The first eccentric shaft 9 utilizes the eccentric principle to convert the rotation into reciprocating eccentric motion, so that the rolling roller 10 produces a periodic left and right rolling action. The outer wall of the first eccentric shaft 9 is fixedly connected to the rolling roller 10. The rolling roller 10 is driven by the first eccentric shaft 9 to perform secondary rolling on the crushed material, further crushing the material to make the material particle size smaller and more uniform, which is convenient for subsequent separation and screening. The rolling box 6 is fixedly connected to the top of the machine body 1, providing a relatively closed space for the rolling process to prevent material splashing, while guiding the flow of materials to ensure that the materials can be fully rolled.

[0022] Please see attached Figure 3 and attached Figure 4 The separation component includes a magnetic roller 17 and a scraper 18. The magnetic roller 17 is rotatably connected to the inside of the machine body 1. The magnetic roller 17 uses the magnetic attraction principle. When the crushed material passes through the surface of the magnetic roller 17, the ferromagnetic metal material in it can be adsorbed on the roller surface to achieve the preliminary separation of metal and non-metal. The scraper 18 is fixedly connected to the inner wall of the machine body 1. As the magnetic roller 17 rotates, the metal material adsorbed on the magnetic roller 17 will be scraped off by the scraper 18 and fall into a specific collection area.

[0023] Please see attached Figure 7The screening assembly includes a plurality of fixed blocks 21, which are fixedly connected to the inner wall of the body 1. The fixed blocks 21 provide support for the screen 23 to ensure that the screening process proceeds smoothly. A first slide bar 22 is fixedly connected between two adjacent fixed blocks 21. The first slide bar 22 provides a sliding track for the screen 23, limiting the reciprocating movement of the screen 23 only in a specific direction. The outer wall of the first slide bar 22 is slidably connected to the screen 23. The screen 23 classifies the crushed materials according to the particle size, so that materials of different particle sizes enter the corresponding collection area. The outer wall of the first slide bar 22 is sleeved with a spring 24, which plays a buffering and resetting role. When the screen 23 is subjected to external force and moves, the spring 24 stores elastic potential energy, and pushes the screen 23 to quickly reset after the external force disappears, thereby maintaining the continuous high-frequency screening action of the screen 23 and improving the screening efficiency.

[0024] Please see attached Figure 2 and attached Figure 4 The transmission assembly includes a second circular gear 13, a third circular gear 16 and two pulleys 14, wherein one pulley 14 is fixedly connected to one of the first circular gears 5, and the other pulley 14 is fixedly connected to the rotating shaft 11, and a belt 15 is sleeved between the two pulleys 14. By installing the two pulleys 14 on the first circular gear 5 and the rotating shaft 11 respectively, and sleeved with the belt 15 between the two pulleys 14, when the first circular gear 5 rotates, the rotating shaft 11 will be driven to rotate under the transmission effect of the pulleys 14 and the belt 15, thereby achieving a force transmission effect, the second circular gear 13 is fixedly connected to the rotating shaft 11, and the third circular gear 16 is fixedly connected to the rotating shaft 11. The gear 16 is fixedly connected to the magnetic roller 17, and the third circular gear 16 is meshed with the second circular gear 13. By fixing the second circular gear 13 on the rotating shaft 11, the third circular gear 16 is fixed on the magnetic roller 17, and the third circular gear 16 and the second circular gear 13 are meshed, when the rotating shaft 11 is driven by the first circular gear 5 to rotate, it will drive the second circular gear 13 to rotate. The second circular gear 13 and the third circular gear 16 are meshed, so the rotation of the second circular gear 13 will also drive the third circular gear 16 to rotate, and further drive the magnetic roller 17 to rotate, so as to realize uninterrupted separation of materials.

[0025] Please see attached Figure 8The reciprocating assembly includes a turntable 25, which is fixedly connected to the side of the magnetic roller 17 away from the third circular gear 16. By fixing the turntable 25 on the magnetic roller 17, when the magnetic roller 17 rotates, the turntable 25 is driven to rotate to achieve force transmission. The outer wall edge of the turntable 25 is fixedly connected to a second eccentric shaft 26. The second eccentric shaft 26 is used to generate eccentric motion when the turntable 25 rotates, and further drive the rotating frame 28 on its outer wall to slide. The second eccentric shaft 26 is fixedly connected to a limited block 27 on the side away from the turntable 25. The limit block 27 is used to limit the rotating frame 28 on the outer wall of the second eccentric shaft 26 to prevent the rotating frame 28 from excessively sliding on the second eccentric shaft 26 and falling off the second eccentric shaft 26. The outer wall of the second eccentric shaft 26 is slidably connected with the rotating frame 28. The rotating frame 28 realizes reciprocating sliding through the rotation of the second eccentric shaft 26, and then the subsequent connecting rod 29 slides. The bottom of the rotating frame 28 is fixedly connected with the connecting rod 29. The connecting rod 29 is used to transmit the reciprocating sliding trajectory generated by the rotating frame 28, thereby driving the subsequent components to achieve the reciprocating sliding effect.

[0026] Please see attached Figure 3 The inner wall of the machine body 1 is fixedly connected with a guide plate 32 and a discharge plate 19 from top to bottom in sequence. The guide plate 32 is used to guide the crushed material to ensure that the material can accurately fall on the magnetic roller 17 to achieve metal separation. The discharge plate 19 is used to guide the metal after separation and scraped off by the scraper 18 to ensure that the metal can be discharged from the inside of the machine body 1. The outer wall of the machine body 1 is provided with three collection boxes 33, and the three collection boxes 33 are respectively used to collect metal materials, larger particle materials and fine particle materials.

[0027] Please see attached Figure 3 -Attached Figure 5 The outer wall of the rolling roller 10 is rotatably connected to the inside of the rolling box 6. By rotatably connecting the rolling roller 10 to the inside of the rolling box 6, the first eccentric shaft 9 is driven to move eccentrically through the rotation of the first bevel gear 8, which further drives the rolling roller 10 to move eccentrically, and squeezes the rolling roller 10 and the inner wall of the rolling box 6 to achieve a rolling effect. The first bevel gear 8 and the second bevel gear 12 are meshed, so that the rolling assembly can respond to the power transmitted from the crushing roller 4 in a timely manner.

[0028] Please see attached Fig. 9 The outer wall of the machine body 1 is provided with two slide grooves 30, and the inner wall of the slide groove 30 is slidably connected with a second slide bar 31, and the second slide bar 31 is fixedly connected to the screen 23. The slide groove 30 provides a sliding track for subsequent components and limits the movement path. The second slide bar 31 is an auxiliary support and movement guide for the screen 23, which enhances the stability of the movement of the screen 23, and cooperates with the first slide bar 22 to make the screen 23 accurately reciprocate on a two-dimensional plane, thereby improving the screening accuracy.

[0029] Please see attached Figure 1 One end of the connecting rod 29 away from the rotating frame 28 is fixedly connected to one of the second sliding rods 31, and the reciprocating motion of the connecting rod 29 is transmitted to the second sliding rod 31, which further drives the screen 23 to slide back and forth, thereby realizing the vibration screening function.

[0030] Please see attached Figure 1 -Attached Figure 3 A feeding port 2 is provided on the top of the machine body 1, and the feeding port 2 is used for providing a device for the scrapped electric meter to enter, so that the operator can conveniently put the electric meter in, and can guide the material to fall accurately into the crushing roller 4 area, thus starting the entire crushing and sorting process.

[0031] Working principle: When it is necessary to process the scrapped electric meter, first, put the scrapped electric meter into the material port 2, and then power on the motor 3. When the motor 3 is powered on, it will convert the electrical energy into mechanical energy, thereby driving one of the crushing rollers 4 to rotate. When the crushing roller 4 rotates, it will drive the first circular gear 5 to rotate, and drive the other first circular gear 5 to rotate through meshing, so as to realize the relative rotation of the two crushing rollers 4, and perform preliminary crushing on the electric meter. When the first circular gear 5 rotates, it will also drive the pulley 14 to rotate. When the pulley 14 rotates, it will It drives the rotating shaft 11 to rotate, and further drives the second bevel gear 12 to rotate. The second bevel gear 12 and the first bevel gear 8 are meshed. Therefore, the rotation of the second bevel gear 12 will transmit the rotation of the rotating shaft 11 to the first bevel gear 8, and change the rotation direction. The rotation of the first bevel gear 8 will drive the rotating block 20 on its top to rotate. The first eccentric shaft 9 fixed on its edge uses the eccentric principle to make the rolling roller 10 fixed on the outer wall produce periodic left and right rolling action, and the crushed material is secondary rolled in the relatively closed space of the rolling box 6 to refine the material particle size and facilitate subsequent separation and screening.

[0032] Then, the material reaches the separation component. The second circular gear 13 in the transmission component rotates to drive the third circular gear 16 fixed on the magnetic roller 17 in meshing engagement therewith to rotate, thereby driving the magnetic roller 17 to rotate. When the crushed material passes through the surface of the magnetic roller 17, the ferromagnetic metal material is adsorbed on the roller surface by the magnetic attraction principle, achieving a preliminary separation of metal and non-metal. As the magnetic roller 17 rotates, the scraper 18 fixed on the inner wall of the body 1 scrapes off the adsorbed metal material and drops it into a specific collection area.

[0033] Finally, the rotation of the magnetic roller 17 drives the turntable 25 fixed thereon to rotate synchronously, and the second eccentric shaft 26 on the edge of the outer wall of the turntable 25 generates eccentric motion, driving the rotating frame 28 slidably connected to the outer wall to swing back and forth, and the connecting rod 29 at the bottom of the rotating frame 28 transmits the motion to the second slide bar 31 fixed at one end to drive the screen 23 to slide back and forth on the first slide bar 22, so that the screen 23 can classify the crushed materials according to the particle size according to different aperture designs, and materials of different particle sizes enter the corresponding collection area.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
