Description

Technical Field

[0001] This invention relates to the field of recycling equipment technology, specifically a metal waste recycling device. Background Technology

[0002] Currently, the processing of various metal parts is basically subtractive processing, which generates a large amount of metal waste during the process. In existing technologies, a recycling tray is generally installed on the machine tool to collect the metal waste and then transport it to a waste disposal site. The metal waste after cutting is spiral or cylindrical in shape and is relatively loose overall.

[0003] Depending on the type of metal being processed, metal waste can be categorized into magnetic waste and non-magnetic waste. Existing recycling equipment commonly uses vibrating screens and drum screens for sorting and recycling waste. However, when sorting magnetic waste, the separation effect between magnetic and non-magnetic waste is poor, and after separation, it is difficult to easily remove the magnetic and non-magnetic waste, resulting in poor utilization efficiency.

Detailed Implementation

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0024] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0025] like Figure 1 , Figure 2 , Figure 3The diagram shows a structural representation of a metal scrap recycling device according to an embodiment of the present invention. The device includes a housing 1, which is cylindrical. Support legs 11 are fixedly installed around the bottom wall of the housing 1. A feed funnel 12 is provided on the top surface of the housing 1, and a bottom guide outlet 13 is provided on the bottom wall. A screening plate 2 is provided inside the housing 1, and an electromagnetic plate 21 is fixedly installed on the surface of the screening plate 2. A positioning mechanism 3 connected to the screening plate 2 is provided on the side wall of the housing 1. The positioning mechanism 3 includes a rotating component 31 and an adjusting component 32. The rotating component 31 is located on the side wall of the housing 1 and connected to the screening plate 2, and is used to drive the screening plate 2 to reciprocate within the housing 1. The adjusting component 32 is connected to the rotating component 31 and is used to adjust the position of the screening plate within the housing 1. The rotation range of the screening plate 2 inside the box 1 is adjusted. The side wall of the box 1 is provided with a discharge mechanism 4. The discharge mechanism 4 includes a first guide assembly 41 and a second guide assembly 42. The first guide assembly 41 is located on both sides of the screening plate 2 and is connected to the side wall of the box 1. The first guide assembly 41 is used to drive the non-magnetic material on the surface of the screening plate 2 to move to the bottom of the box 1. The second guide assembly 42 includes a side discharge port 421, a sealing part 422 and a through part 423. The side discharge port 421 is located on the side wall of the box 1. The sealing part 422 is located inside the side discharge port 421 and is used to control the side discharge port 421 to be in a closed state. The through part 423 is connected to the sealing part 422 and is used to control the side discharge port 421 to switch to an open state.

[0026] In use, the metal waste to be recycled is fed into the inner cavity of the housing 1 through the feeding funnel 12. The metal waste falls onto the surface of the screening plate 2. When the electromagnetic plate 21 is energized, it attracts the magnetic waste in the metal waste through magnetic attraction. During the attraction process, the rotating component 31 controls the screening plate 2 to rotate back and forth in the inner cavity of the housing 1. When the screening plate 2 rotates, the metal waste on the surface of the screening plate 2 moves from the higher side to the lower side. During the reciprocating movement, the metal waste can be evenly spread on the surface of the screening plate 2, and the electromagnetic plate 21 can efficiently attract and position the magnetic waste in the metal waste. After the magnetic waste is attracted and fixed, the adjusting component 32 can increase the rotation amplitude of the screening plate 2. When the screening plate 2 rotates to the tilt angle, the first guide component 41 can release the restriction on the non-magnetic waste on the surface of the screening plate 2. The non-magnetic waste on the surface of the screening plate 2 slides off the surface of the screening plate 2 and falls further into the bottom of the housing 1. The bottom guide port 13 can be opened to easily remove the non-magnetic waste. After the non-magnetic waste is removed from the surface of the screening plate 2, the adjusting component 32 can further increase the rotation amplitude of the screening plate 2. During the process of the screening plate 2 rotating to the tilt, the through part 423 can control the side discharge port 421 to switch to the open state. At this time, the electromagnetic plate 21 is de-energized, and the electromagnetic plate 21 releases the restriction on the magnetic metal waste. The magnetic waste slides down the tilted surface of the screening plate 2, and can guide the magnetic waste on the surface of the screening plate 2 to be discharged from the side discharge port 421.

[0027] like Figure 1 , Figure 4 , Figure 5 As shown, in a preferred embodiment of the present invention, the rotating assembly 31 includes a horizontal column 311 rotatably mounted inside the cavity of the housing 1, the screening plate 2 is fixedly mounted on the surface of the horizontal column 311, one end of the horizontal column 311 extends to the outside of the housing 1 and is fixedly mounted with a guide plate 312, the surface of the guide plate 312 is provided with a guide groove 313, a motor 314 is fixedly mounted on the side wall of the housing 1, the output shaft of the motor 314 is fixedly mounted with a control disk 315, and a guide protrusion 316 is provided on the surface of the control disk 315 at a position off-center, the guide protrusion 316 is inserted into the guide groove 313.

[0028] In use, the motor 314 drives the control panel 315 to rotate, the control panel 315 drives the guide protrusion 316 to rotate, the guide protrusion 316 rotates in the guide groove 313, which can control the guide plate 312 to reciprocate on the outside of the box 1, the guide plate 312 drives the horizontal column 311 to reciprocate in the cavity of the box 1, and the horizontal column 311 drives the screening plate 2 to reciprocate synchronously in the cavity of the box 1 to the tilted state.

[0029] like Figure 1 , Figure 4 , Figure 5As shown, in a preferred embodiment of the present invention, the adjustment component 32 includes a fixing groove 321 formed on the surface of the control disk 315. The fixing groove 321 is distributed along the diameter direction of the control disk 315. A sliding block 322 is slidably installed in the fixing groove 321. The guide protrusion 316 is fixedly installed on the surface of the sliding block 322. An electric telescopic rod 323 is fixedly installed in the fixing groove 321. The telescopic end of the electric telescopic rod 323 is connected to the sliding block 322.

[0030] The sliding block 322 positions the guide protrusion 316 on the surface of the control panel 315. When it is necessary to adjust the rotation amplitude of the screening plate 2, the electric telescopic rod 323 pushes the sliding block 322 to move in the fixed groove 321. The sliding block 322 drives the guide protrusion 316 to move synchronously on the surface of the control panel 315. By adjusting the position of the guide protrusion 316, the rotation amplitude of the screening plate 2 can be easily adjusted.

[0031] like Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 As shown, in a preferred embodiment of the present invention, the first guide assembly 41 includes end plates 411 respectively disposed on both sides of the screening plate 2, magnetic strips 412 are fixedly installed on the two side walls of the end plates 411 opposite to the screening plate 2, and baffles 413 are fixedly installed on the inner side wall of the box body 1.

[0032] Initially, the magnetic strip 412 connects the screening plate 2 and the end plate 411 into a single unit through magnetic attraction. As the screening plate 2 reciprocates, it drives the end plate 411 to move synchronously. During screening, the end plate 411 effectively prevents metal waste from sliding off both sides of the screening plate 2. Once the magnetic waste is attracted and fixed, the rotation amplitude of the screening plate 2 is increased. As the screening plate 2 rotates to an inclined position, the baffle 413 restricts the end plate 411, causing it to fall onto the surface of the baffle 413. At this point, the screening plate 2 and the end plate 411 separate. After the screening plate 2 rotates below the baffle 413, the non-magnetic waste on the surface of the screening plate 2 slides off and further falls to the bottom of the housing 1. When the screening plate 2 rotates upwards towards the baffle 413, the magnetic strip 412 again fixes the end plate 411 to both sides of the screening plate 2 through magnetic attraction.

[0033] like Figure 2 , Figure 3 , Figure 6 , Figure 8As shown, in a preferred embodiment of the present invention, the sealing part 422 includes a receiving cavity 4221 with the bottom wall of the side discharge port 421 opening downward. A sealing plate 4223 is slidably installed in the receiving cavity 4221. A compression spring 4222 is fixedly installed on the bottom wall of the receiving cavity 4221. The extension end of the compression spring 4222 is connected to the sealing plate 4223.

[0034] Initially, the compression spring 4222 applies a pushing force to the sealing plate 4223, and the sealing plate 4223 is entirely within the side discharge port 421. The sealing plate 4223 controls the side discharge port 421 to be in a sealed state, effectively preventing non-magnetic waste from being discharged from the side discharge port 421 when it slides off the surface of the screening plate 2. When the rotation amplitude of the screening plate 2 is further increased, during the process of rotating the screening plate 2 to the tilted state, the through part 423 pushes the sealing plate 4223 to move into the receiving cavity 4221. At this time, the side discharge port 421 switches to an open state, and the magnetic waste on the surface of the screening plate 2 can pass through the side discharge port 421 and move to the outside of the box 1.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 8 As shown, in a preferred embodiment of the present invention, the through portion 423 includes a guide plate 4231 slidably mounted on the surface of the sealing plate 4223. An inner positioning strip 4232 is fixedly mounted on the side of the guide plate 4231 facing the inner cavity of the housing 1, and an outer positioning strip 4233 is fixedly mounted on the side of the guide plate 4231 facing the outside of the housing 1. Both the inner positioning strip 4232 and the outer positioning strip 4233 are made of magnetic material. Magnetic sheets 4234 are fixedly mounted on the inner and outer side walls of the sealing plate 4223.

[0036] Initially, the inner positioning strip 4232 and the magnetic sheet 4234 on the inner side of the guide plate 4231 are connected as a whole by magnetic attraction, and the guide plate 4231 is located outside the sealing plate 4223. When it is necessary to remove the magnetic waste from the surface of the screening plate 2, the guide plate 4231 is pushed to move into the inner cavity of the box 1. At this time, the outer positioning strip 4233 and the magnetic sheet 4234 are connected as a whole. During the rotation and tilting process of the screening plate 2, the bottom wall of the screening plate 2 contacts the guide plate 4231, and the screening plate 2 pushes the guide plate 4231 downward, which can further push the sealing plate 4223 into the receiving cavity 4221.

[0037] like Figure 1 , Figure 5 As shown, in a preferred embodiment of the present invention, a fixing frame 5 is fixedly installed on the side wall of the housing 1. The fixing frame 5 has a U-shaped structure, and the output shaft of the motor 314 is rotatably connected to the fixing frame 5.

[0038] The mounting bracket 5 can effectively improve the stability of the output shaft of motor 314 during rotation.

[0039] The working principle of this invention is as follows: During use, the metal waste to be recycled is fed into the inner cavity of the housing 1 through the feeding funnel 12. The metal waste falls onto the surface of the screening plate 2. When the electromagnetic plate 21 is energized, it attracts the magnetic waste within the metal waste using magnetic attraction. During this attraction process, the motor 314 drives the control disk 315 to rotate, which in turn drives the guide protrusion 316 to rotate. The guide protrusion 316 rotates within the guide groove 313, controlling the guide plate 312 to reciprocate on the outside of the housing 1. The guide plate 312 drives the horizontal column 311 to reciprocate within the inner cavity of the housing 1, and the horizontal column 311 drives the screening plate 2 to synchronously reciprocate to an inclined state within the inner cavity of the housing 1. As the screening plate 2 rotates, the metal waste on its surface moves from the higher side to the lower side. During this reciprocating movement, the metal waste can be evenly spread across the surface of the screening plate 2, allowing the electromagnetic plate 21 to efficiently attract and position the magnetic waste within the metal waste.

[0040] When the screening plate 2 rotates, the metal waste on the surface of the screening plate 2 moves from the high side to the low side. During the reciprocating movement, the metal waste can be evenly spread on the surface of the screening plate 2, and the electromagnetic plate 21 can efficiently adsorb and position the magnetic waste in the metal waste.

[0041] After the magnetic waste is adsorbed and fixed, the rotation amplitude of the screening plate 2 is increased. During the rotation of the screening plate 2 to the tilting process, the baffle 413 restricts the end plate 411, and the end plate 411 falls on the surface of the baffle 413. At this time, the screening plate 2 and the end plate 411 separate from each other. After the screening plate 2 rotates to below the baffle 413, the non-magnetic waste on the surface of the screening plate 2 slides off the surface of the screening plate 2 and further falls to the bottom of the box 1. When the screening plate 2 rotates upward toward the baffle 413, the magnetic strip 412 fixes the end plate 411 to both sides of the screening plate 2 again through magnetic attraction.

[0042] When it is necessary to remove the magnetic waste from the surface of the screening plate 2, the guide plate 4231 is pushed to move into the inner cavity of the housing 1. At this time, the outer positioning strip 4233 and the magnetic sheet 4234 are connected as a whole. When the rotation range of the screening plate 2 is further increased, during the process of rotating to the tilted state, the bottom wall of the screening plate 2 contacts the guide plate 4231. The screening plate 2 pushes the guide plate 4231 downward, which can further push the sealing plate 4223 into the receiving cavity 4221. At this time, the side discharge port 421 switches to the open state. At this time, the electromagnetic plate 21 is de-energized, and the magnetic waste on the surface of the screening plate 2 can move through the side discharge port 421 to the outside of the housing 1.

[0043] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
