Description

Technical Field

[0001] This utility model belongs to the field of crushing equipment, specifically relating to a device for crushing recycled aluminum into fragments. Background Technology

[0002] Recycled aluminum refers to aluminum materials obtained through recycling and reprocessing aluminum waste or aluminum products. Compared with primary aluminum, the production process of recycled aluminum consumes less energy and has a smaller environmental impact. Recycled aluminum can be used to manufacture various aluminum products, such as beverage cans, building materials, and automotive parts. Recycled aluminum products usually require crushing during recycling.

[0003] In the prior art, such as the Chinese patent application number CN202123429717.2, the aforementioned patent uses a starting motor to drive a rotating shaft and one of the crushing rollers to rotate clockwise. Three driven gears drive another crushing roller to rotate counterclockwise. Aluminum blocks are fed from the top of the feed box and quickly crushed. Although the aforementioned patent can crush aluminum products, when crushing lightweight aluminum cans such as beverage bottles, the aluminum cans are easily tumbled on the upper part of the crushing rollers during the rotation of the crushing rollers. This makes it difficult for the aluminum cans to effectively enter the biting and crushing area of ​​the two crushing rollers. Therefore, the prior art has the problem that lightweight aluminum cans are easy to tumble during the crushing process, making it difficult for the aluminum cans to effectively enter the biting and crushing area. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for crushing recycled aluminum into fragments, which solves the problem in the existing technology that the aluminum can easily roll over during the crushing process, making it difficult for the aluminum can to effectively enter the crushing zone.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A device for crushing recycled aluminum into fragments, including a crushing chamber;

[0007] The crushing box is a rectangular frame with openings at both the top and bottom. Inside the crushing box, there is a pair of rotating rollers placed side by side. The rollers are both horizontally positioned and each roller is fixedly fitted with multiple crushing wheels that are evenly distributed along the axial direction. The crushing wheels on the two rollers are arranged in an alternating manner. The crushing box is equipped with a first driving component for driving the two rollers to rotate.

[0008] A pressure plate is located directly above the crushing box. A second driving component is provided on the crushing box to connect the pressure plate. The second driving component is used to drive the pressure plate to move up and down, and the lower end of the pressure plate can be moved down to extend into the inside of the crushing box.

[0009] The principle and effect of the above technical solution are as follows:

[0010] In use, pour the aluminum can into the upper part of the two rotating rollers in the crushing box, then turn on the first drive unit. The first drive unit drives the two rotating rollers to rotate, and the rotating rollers drive the crushing wheel. The rotation of the crushing wheel driven by the two rotating rollers crushes the aluminum can. At the same time, the second drive unit drives the pressure plate to move up and down. Each time the pressure plate moves down, it presses the aluminum can at the upper part of the two rotating rollers downward, which can push the aluminum can towards the crushing wheel, so that the aluminum can enter the biting crushing state more effectively and improve the crushing efficiency.

[0011] At the same time, the pressing of the pressure plate can also reduce the phenomenon of aluminum cans being pushed and tumbling on the upper end of the two rollers, increasing the chance of biting and crushing, thereby further improving the crushing efficiency.

[0012] Both ends of the rotating roller extend horizontally to the outside of the crushing box;

[0013] The first driving component includes a pair of first gears, which are respectively fixedly sleeved on two rotating rollers.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] This combination Figures 1 to 4 This describes an embodiment of a device for crushing recycled aluminum into shreds. Specifically, the device is constructed as a split structure, comprising a crushing box 100, rotating rollers 200, crushing wheels 201, a first driving component, a pressure plate 400, and a second driving component. The first driving component drives the two rotating rollers 200 to rotate, which in turn drives the crushing wheels 201. The rotation of the two rotating rollers 200 and the crushing wheels 201 crushes the aluminum can. Simultaneously, the second driving component drives the pressure plate 400 to move up and down. Each time the pressure plate 400 moves down, it presses down on the aluminum can at the upper end of the two rotating rollers 200, pushing the aluminum can towards the crushing wheels 201, thus promoting more effective crushing and improving crushing efficiency.

[0033] At the same time, the pressing of the pressure plate 400 can also reduce the phenomenon of aluminum cans being moved and tumbling on the upper end of the two rotating rollers 200, increase the chance of biting and crushing, and thus further improve the crushing efficiency.

[0034] Please refer to Figures 1 to 4 A device for crushing recycled aluminum into fragments, comprising a crushing chamber 100, characterized in that:

[0035] The crushing box 100 is a rectangular frame with openings at both the top and bottom. Inside the crushing box 100, there is a pair of rotating rollers 200 placed side by side. The rollers 200 are both placed horizontally. Multiple crushing wheels 201 are fixedly sleeved on each roller 200 along the axial direction and are evenly distributed. The crushing wheels 201 on the two rollers 200 are arranged in an alternating manner. The crushing box 100 is provided with a first driving member for driving the two rollers 200 to rotate.

[0036] A pressure plate 400 is provided directly above the crushing box 100. A second driving component is provided on the crushing box 100 to connect the pressure plate 400. The second driving component is used to drive the pressure plate 400 to move up and down, and the lower end of the pressure plate 400 can be moved down to extend into the inside of the crushing box 100.

[0037] The crushing box 100 is preferably made of high-strength steel, which gives it good wear resistance and impact resistance. The surface of the crushing box 100 is coated to prevent corrosion and increase its service life.

[0038] The crushing wheel 201 is preferably made of high carbon steel, which gives it excellent hardness and wear resistance. The crushing wheel 201 can be designed with convex teeth on its peripheral wall to increase crushing efficiency. The staggered arrangement ensures full contact of materials during the crushing process and improves the crushing effect.

[0039] The pressure plate 400 can be made of metal materials such as stainless steel or aluminum alloy, so that the pressure plate 400 itself has sufficient weight to squeeze the aluminum can.

[0040] In use, the aluminum can is poured into the upper part of the two rotating rollers 200 inside the crushing box 100. Then, the first drive unit is turned on, which drives the two rotating rollers 200 to rotate. The rotating rollers 200 drive the crushing wheel 201. The aluminum can is crushed by the rotation of the crushing wheel 201 driven by the two rotating rollers 200. At the same time, the pressure plate 400 is driven to move up and down by the second drive unit. Each time the pressure plate 400 moves down, it presses the aluminum can at the upper part of the two rotating rollers 200 downward, which can push the aluminum can towards the crushing wheel 201, so that the aluminum can enter the biting crushing state more effectively and improve the crushing efficiency.

[0041] At the same time, the pressing of the pressure plate 400 can also reduce the phenomenon of aluminum cans being moved and tumbling on the upper part of the two rotating rollers 200, increase the chance of biting and crushing, and thus further improve the crushing efficiency.

[0042] To facilitate the synchronous rotation of the two rotating rollers 200, both ends of the rotating rollers 200 extend horizontally to the outside of the crushing box 100;

[0043] The first driving component includes a pair of first gears 301, which are fixedly sleeved on two rotating rollers 200 respectively. The first gears 301 are located on the outside of the crushing box 100 and the two first gears 301 mesh with each other. A rotating motor 302 is fixedly installed on the outer wall of the crushing box 100, and the output end of the rotating motor 302 is connected to any rotating roller 200.

[0044] Turn on the rotating motor 302. The output end of the rotating motor 302 drives the rotating roller 200 connected to it. The rotating roller 200 drives the first gear 301. Through the meshing of the two first gears 301, the two rotating rollers 200 are driven to rotate synchronously.

[0045] The second driving component includes a support bar 501 horizontally fixed to the outer wall of the crushing box 100. The support bar 501 is placed coaxially with the rotating roller 200. Multiple vertically placed sliding rods 502 are fixed on the support bar 501. A connecting plate 503 is fixed to the upper end of the pressure plate 400. The upper ends of the sliding rods 502 all pass through the connecting plate 503 and are slidably connected to the connecting plate 503. The sliding rods 502 improve the guiding and stability of the reciprocating lifting and lowering movement of the pressure plate 400.

[0046] The second driving component also includes a pair of symmetrically placed second gears 504. The two second gears 504 are fixedly sleeved on either of the rotating rollers 200. Both second gears 504 are located outside the crushing box 100, and are respectively located at both ends of the crushing box 100. Vertically downward-placed racks 505 are fixed to both ends of the connecting plate 503. Each rack 505 corresponds one-to-one with a second gear 504, and each rack 505 meshes with its corresponding second gear 504. Both rotating rollers 200 are located on the same side of the racks 505. Each second gear 504 has a toothed groove 5041. When the toothed groove 5041 rotates to face the rack 505... The second gear 504 separates from the rack 505. Since the two first gears 301 need to maintain a downward rotation direction at their close ends during the meshing and breaking process, the rotating roller 200 will also drive the second gear 504 simultaneously during the rotation. The second gear 504 drives the rack 505 to move upward, and the second rack 505 drives the connecting plate 503 and the pressure plate 400 to move upward. When the toothed groove 5041 rotates to face the rack 505, the second gear 504 separates from the rack 505. Under the action of gravity, the pressure plate 400 and the connecting plate 503 slide downward, and then the pressure plate 400 squeezes the aluminum can at the upper end of the two rotating rollers 200 downward.

[0047] To improve the extrusion effect on the aluminum can, springs 506 are fitted on the slide rods 502. The lower ends of the springs 506 are fixed to the support bars 501, and the upper ends of the springs 506 are fixed to the connecting plates 503. The springs 506 are always in a stretched state. The extrusion effect on the aluminum can can be improved by the tension of the springs 506, combined with the gravity of the pressure plate 400 and the connecting plate 503.

[0048] Each rack 505 has a vertically placed slot 5051. A pair of corresponding clips 507 are fixed on the outer wall of the crushing box 100. One end of each clip 507 is slidably engaged in the corresponding slot 5051. The cooperation between the slot 5051 and the clip 507 can further improve the guiding performance of the rack 505 during movement.

[0049] The upper end of each slide rod 502 is fixedly connected to a limiting plate 508; the limiting plate 508 is used to prevent the connecting plate 503 from moving too high and detaching from the slide rod 502.
