Description

Technical Field

[0001] This invention relates to the field of end-of-life vehicle recycling technology, and more particularly to a device for recycling scrap metal materials from crushed end-of-life vehicles. Background Technology

[0002] As an important material resource, scrapped cars have a high residual value and can be recycled and reused in a market-oriented manner. After years of exploration, especially with the adoption of recycling technologies and equipment, it is now possible to recycle and reuse the parts of each car. Among them, the non-ferrous metals need to be separated after the scrapped car components are crushed.

[0003] For example, the patent with publication number CN213287268U, entitled "A Non-ferrous Metal Separation Device for Scrap Automobiles", and authorized announcement date of 20210528, includes a separation device. The separation device includes a screening and feeding device and an eddy current separator fixed at the right discharge end of the screening and feeding device. The front surface of the eddy current separator is embedded with an observation window. The screening and feeding device includes a sound-absorbing shell and a vibrating screen and a damping component fixed from top to bottom in the inner cavity of the sound-absorbing shell. The eddy current separator includes a machine body and a conveyor belt fixed at the upper end of the inner cavity of the machine body. The conveyor belt has a conveyor rotating wheel and an eddy current magnetic roller fixed on the left and right sides respectively. Protective plates are installed on the front and rear sides of the conveyor belt. A non-ferrous metal outlet is opened on the right surface of the machine body, and a non-metallic outlet is opened at the lower end of the machine body. A baffle is provided on the right side of the conveyor belt. In this non-ferrous metal separation device for scrap automobiles, the damping component at the lower end reduces vibration. The damping component absorbs vibration through internal springs, greatly reducing the vibration.

[0004] The shortcoming of the existing technology is that, after the scrapped car is crushed and screened, magnetic and non-magnetic metals are mixed together, and different metals need to be recycled separately. The existing technology uses permanent magnet roller adsorption to screen and recycle magnetic metals. However, when the permanent magnet roller adsorbs magnetic metals, it does not clean up the smaller magnetic debris. During the long screening process of magnetic metals, too much magnetic debris is adsorbed on the outer surface of the permanent magnet roller, which reduces the effect of the permanent magnet roller in adsorbing magnetic metals and affects the recycling effect of magnetic and non-magnetic metals. Summary of the Invention

[0005] The purpose of this invention is to provide a recycling device for scrap metal materials from crushed end-of-life vehicles. The device uses a drive shaft to rotate a cleaning component to clean the debris adsorbed by a permanent magnet roller, thereby improving the continuous adsorption and sorting effect of the permanent magnet roller. A support component symmetrically arranged at the bottom of the sorting box limits the positioning frame. The positioning frame slides on the support component and is fixed to the support component by bolts. The positioning frame limits and adheres the cleaning component to the surface of the permanent magnet roller, enabling the cleaning component to adhere to and clean the debris adsorbed on the irregular structure of the outer surface of the permanent magnet roller.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] Reference Figure 1-10A recycling device for scrap metal materials from crushed end-of-life vehicles includes a sorting box 1 and a sorting assembly 2 for screening within the sorting box 1. The sorting assembly 2 includes a drive shaft 21, with a permanent magnet roller 22 symmetrically fixed to the drive shaft 21. A limit strip 23 is fixed to the outer surface of the permanent magnet roller 22. One end of the drive shaft 21 passes through the sorting box 1 and has an input end 211. A drive assembly 3 is driven through the input end 211 to drive the drive shaft 21 to move and sort the metal materials in the recycling material in the sorting box 1 through the permanent magnet roller 22. The other end of the drive shaft 21 has an output end 212, which is driven through the output end 212 to drive a cleaning component 7. The cleaning component 7 rotates and cleans the metal materials adsorbed by the permanent magnet roller 22. The device also includes a support component 4, which is symmetrically arranged at both ends of the sorting box 1. A limit frame 5 is slidably provided within the support frame. The limit frame 5 adheres the cleaning component 7 to the permanent magnet roller 22, achieving a highly adaptive fit between the cleaning component 7 and the outer surface of the permanent magnet roller 22.

[0040] Specifically, the sorting box 1 has a rectangular frame structure. Inside the sorting box 1, the sorting component 2 rotates via the drive component 3. The drive shaft 21 in the sorting component 2 drives the fixed permanent magnet roller 22 to rotate. The permanent magnet roller 22 attracts magnetically adsorbed metal materials from the recycled material to its surface, while non-magnetically adsorbed metal materials slide off as the permanent magnet roller 22 rotates. The metal materials adsorbed on the outer surface of the permanent magnet roller 22 press against the cleaning component 7 and fall off, thus achieving the separation of magnetically adsorbed and non-magnetically adsorbed metal materials from the recycled material by the permanent magnet roller 22. The drive shaft 21 is fixedly connected through the permanent magnet roller 22, passing through the sorting box 1 and connected to the drive component 3 via its input end 211. Its output end 212 is connected to the cleaning component 7. Driven by the drive component 3, the permanent magnet roller 22 is rotated via the transmission shaft 21. At the same time, the cleaning component 7 rotates against the surface of the permanent magnet roller 22. The cleaning component 7 cleans the metal material adsorbed on the permanent magnet roller 22 and cleans the debris adsorbed on the permanent magnet roller 22 by rotating the cleaning component 7 via the transmission shaft 21, thereby improving the continuous adsorption and sorting effect of the permanent magnet roller 22. The support component 4, which is symmetrically arranged at the bottom of the sorting box 1, limits the limit frame 5. The limit frame 5 is slidably set on the support component 4 and limited on the support component 4 by bolts. The limit frame 5 limits the cleaning component 7 to adhere to the surface of the permanent magnet roller 22, so that the cleaning component 7 can adhere to and clean the irregular structure on the outer surface of the permanent magnet roller 22 and the debris adsorbed on the outer surface of the permanent magnet roller 22.

[0041] The cleaning component 7 includes a cleaning roller 71, a rotating rod 72 fixedly connected inside the cleaning roller 71, a driven wheel 73 fixedly connected to one end of the rotating rod 72, a belt 67 sleeved on the outside of the driven wheel 73, and the end of the belt 67 away from the driven wheel 73 is sleeved on the output end 212; specifically, the cleaning component 7 is welded to the cleaning roller 71 through the rotating rod 72, and the driven wheel 73 fixedly connected to the rotating rod 72 and the belt 67 sleeved on the output end 212 realize that when the drive shaft 21 rotates, the driven wheel 73 is driven to rotate through the belt 67, and the driven wheel 73 is fixedly connected to the cleaning roller 71 through the rotating rod 72, so that the cleaning roller 71 cleans the debris adsorbed on the outer surface of the permanent magnet roller 22 by rotating.

[0042] The support component 4 includes a support base 41, within which a rotating shaft seat 42 is provided, and the rotating shaft seat 42 limits the support base 41 to the sorting box 1. One end of the support base 41 is provided with a sliding rod 43, and the end of the sliding rod 43 away from the support base 41 is fixedly connected to a base plate 44. A sliding plate 51 is slidably connected to the sliding rod 43. A connecting strip 52 is symmetrically fixedly connected to one end of the sliding plate 51, and a sliding strip 53 is fixedly fixedly connected to the end of the connecting strip 52 away from the sliding plate 51. The sliding strip 53 is slidably connected to the sliding rod 43. Support springs 56 are symmetrically fixedly connected to both ends of the sliding plate 51, and the support... Spring 56 is fixedly connected to limiting arm 742; directional grooves 55 are symmetrically opened at both ends of connecting bar 52, and slider 743 is slidably arranged in the directional grooves 55; an internal sliding groove 54 is opened in the connecting bar 52, and the internal sliding groove 54 is adapted to the rotating rod 72; sliding frame 74 is symmetrically provided at both ends of driven wheel 73, and sliding frame 74 is movably connected to rotating rod 72; sliding frame 74 includes rotating sleeve 741 for movably connecting rotating rod 72; limiting arm 742 is symmetrically fixedly connected at both ends of rotating sleeve 741; slider 743 is fixedly connected to one end of limiting arm 742.

[0043] Specifically, the support 4 is connected to the rotating shaft seat 42 welded to the sorting box 1 via the support base 41. The support base 41 adjusts the tilt angle of the slide rod 43 fixed to it by rotating along the rotating shaft seat 42. The sliding plate 51, slidably connected within the slide rod 43, is positioned by fastening bolts, thus limiting its position on the slide rod 43. The built-in groove 54 within the connecting strip 52, fixed to the sliding plate 51, limits the direction of movement of the rotating rod 72. When the outer surface of the permanent magnet roller 22... When the fixed limiting strip 23 abuts against the cleaning roller 71, the rotating roller fixed to the cleaning roller 71 moves along the built-in slide groove 54. The limiting arm 742 fixed to the rotating sleeve 741 movably connected to the rotating rod 72 is limited in the directional groove 55 opened in the connecting strip 52 by the slider 743, so that the rotating rod 72 moves in a directional manner along the built-in slide groove 54. The cleaning roller 71 is attached to the outer surface of the permanent magnet roller 22 by the support fixed to the sliding plate 51, so that the cleaning roller 71 can adapt to the irregular permanent magnet roller 22 surface for fitting.

[0044] It also includes a tensioning component 6, which includes a connecting rod 75, and the connecting rod 75 is fixed to the end of the rotating rod 72. The connecting rod 75 is fitted with a connecting rod 64, and the end of the connecting rod 64 away from the connecting rod 75 is movably connected to a swing arm 63. The bottom end of the swing arm 63 is fixedly connected to a connecting rod 62. The connecting rod 62 passes through a fixing ear 61 and is fixedly connected to a support arm 65. The fixing ear 61 is fixed to a sliding strip 53. The top end of the support arm 65 is rotatably connected to a tension wheel 66, and the tension wheel 66 is attached to a belt 67. The drive assembly 3 includes a support plate 31, and the support plate 31 is fixed to the sorting box 1. The bottom end of the support plate 31 is fixedly connected to a drive motor 32. The gear end of the drive motor 32 meshes with a gear disk 33. A transmission belt 34 is fitted on the outside of the gear disk 33, and the end of the transmission belt 34 away from the gear disk 33 is fitted on the input end 211.

[0045] Specifically, the connecting rod 75 fixed to the end of the rotating rod 72 drives the swing arm 63 to move along the axis of the connecting rod 62 via the connecting rod 64. The connecting rod 62 is fixed to the sliding bar 53 via the fixing lug 61, and the connecting rod 62 is rotatably connected to the fixing lug 61. When the swing arm 63 is driven by the connecting rod 64, it drives the tension wheel 66, which is rotatably connected to the top of the support arm 65, to move via the connecting rod 62. The tension wheel 66 abuts against the belt 67 sleeved on the driven wheel 73 and the output end 212. When the cleaning roller 71 is fixed to the limiting strip 23 on the outer surface of the permanent magnet roller 22, it abuts against the built-in sliding groove 5. 4. During directional movement, the connecting rod 64 drives the tension wheel 66 to move along the axis of the connecting rod 62 through the support arm 65, so that the tension wheel 66 prevents the belt 67 from loosening. However, the rotating rod 72 drives the driven wheel 73 to move, so that the belt 67 sleeved on the output end 212 and the driven wheel 73 remains taut. This allows the cleaning roller 71 to move along the outer contour formed by the limiting strip 23 fixed to the permanent magnet roller 22, and to drive the cleaning roller 71 through the transmission shaft 21 to clean the debris adsorbed by the permanent magnet roller 22, thereby improving the efficiency of continuous cleaning of the permanent magnet roller 22.

[0046] The sorting box 1 includes a box body 11. A partition plate 12 is fixedly connected inside the box body 11. The partition plate 12 divides the box body 11 into two cavities, and guide plates 13 are provided inside the cavity. The guide plates 13 are fixedly connected to the box body 11.

[0047] Working principle: The sorting box 1 is placed at the end of the conveyor belt that transports shredded metal from scrapped cars. The conveyor belt feeds the shredded metal into the sorting box 1. The sorting box 1 is divided into two chambers by a partition plate 12 to facilitate a preliminary simple screening of the shredded metal falling from the conveyor belt. The heavier shredded metal is sent to the chamber closer to the conveyor belt, and the lighter shredded metal is sent to the other separated chamber. The shredded metal is then guided by a guide plate 13 fixed to the box body 11 inside the chamber to the permanent magnet roller 22 for sorting. The drive motor 32 in the drive assembly 3 is started to drive the transmission shaft 21 to rotate. The transmission shaft 21 drives the permanent magnet roller 22 to rotate. The permanent magnet roller 22 attracts magnetically adsorbed metal materials from the recycled material to its surface. Non-magnetically adsorbed metal materials slide off as the permanent magnet roller 22 rotates. The metal materials adsorbed on the outer surface of the permanent magnet roller 22 are pressed against the cleaning part 7 and fall off. This achieves the separation of magnetically adsorbed and non-magnetically adsorbed metal materials from the recycled material by the permanent magnet roller 22. Driven by the drive assembly 3, the shredded metal materials are transported to the box body 1. The drive shaft 21 drives the permanent magnet roller 22 to rotate. When the limiting strip 23 on the outer surface of the permanent magnet roller 22 abuts against the cleaning roller 71, the rotating rod 72 fixed to the cleaning roller 71 moves along the built-in slide groove 54. The limiting arm 742 fixed to the rotating sleeve 741 connected to the rotating rod 72 is limited in the directional groove 55 opened in the connecting strip 52 by the slider 743, so that the rotating rod 72 moves in a directional manner along the built-in slide groove 54. At the same time, the connecting rod 64 drives the tension wheel 66 along the connecting rod 62 through the support arm 65. The movement at the axis prevents the tensioning wheel 66 from loosening the belt 67, but the rotating rod 72 drives the driven wheel 73 to move, so that the belt 67 sleeved on the output end 212 and the driven wheel 73 remains taut. This causes the cleaning component 7 to rotate against the surface of the permanent magnet roller 22. The cleaning component 7 cleans the metal material adsorbed on the permanent magnet roller 22 and, through the drive shaft 21, drives the cleaning component 7 to rotate, thus cleaning the debris adsorbed on the permanent magnet roller 22 and improving the continuous sorting of adsorbed metal material by the permanent magnet roller 22.
