Abstract

According to the magnesium alloy leftover material double-shaft shredding machine, after the magnesium alloy leftover material double-shaft shredding machine stops working, the rotating column is locked and fixed through the locking mechanism. Specifically, the bearing ring is driven by the driving column to drive the rotating ring to rotate along the annular rotating groove. In the process, one end of the driving connecting rod is rotationally connected with the annular connecting plate through the rotating rod, meanwhile, the sliding sleeve is arranged on the driving connecting rod in a sleeving mode and is in sliding connection with the driving connecting rod, and the sliding sleeve is rotationally connected with the bearing ring through the rotating connecting rod. And when the driving connecting rod rotates, the clamping block and the other two clamping blocks are driven to get close to each other to extrude and lock the rotating column. After the rotating column is locked, the threaded rod is driven to rotate by rotating the handle, and the extrusion plate is driven to move close to the annular connecting plate and abut against the annular connecting plate in the rotating process of the threaded rod, so that the relative position of the driving column and the annular connecting plate is fixed, and the locking state of the rotating column is fixed.

Description

Technical Field

[0001] This utility model relates to the field of magnesium alloy scrap processing, and in particular to a dual-shaft shredder for magnesium alloy scrap. Background Technology

[0002] Magnesium alloys are alloys composed of magnesium as a base and other elements. Magnesium alloys have low density, high strength, high elastic modulus, good heat dissipation, good vibration damping, and a greater ability to withstand impact loads than aluminum alloys. They also exhibit good resistance to corrosion from organic substances and alkalis. The main alloying elements in magnesium alloys include aluminum, zinc, manganese, cerium, thorium, and small amounts of zirconium or cadmium. Magnesium-aluminum alloys are the most widely used, followed by magnesium-manganese alloys and magnesium-zinc-zirconium alloys. As a sub-sector of the non-ferrous metal alloy industry, the magnesium alloy industry has benefited from the upgrading of the manufacturing industry. As a capital- and material-intensive industry, stable and low raw material prices, consolidation and concentration in the casting industry, and advancements in technological research and development will all be conducive to the development of the magnesium alloy industry.

[0003] However, the production and processing of magnesium alloys inevitably generates a large amount of magnesium alloy scrap. To recycle this scrap, a shredder is needed to crush it. Traditional shredders, such as the one protected by the patent application CN201910379642.X entitled "A Twin-Shaft Shredder for Shredding Cylindrical Objects," lack a locking function when not in operation, posing a certain safety hazard. Utility Model Content

[0004] Therefore, it is necessary to address the technical problem that traditional shredders do not have a locking function for shredders in non-working states, which poses certain safety hazards, and to provide a dual-shaft shredder for magnesium alloy scrap.

[0005] A dual-shaft shredder for magnesium alloy scrap includes: a support frame, a receiving frame, two shredding mechanisms, and two locking mechanisms.

[0006] The support frame includes a support plate and a plurality of support columns, with each support column evenly arranged on the edge of the support plate; a discharge port is provided in the middle area of ​​the support plate.

[0007] The receiving frame is located at the discharge port and connected to the support frame; the two shredding mechanisms are respectively located on both sides of the receiving frame and connected to the support frame;

[0008] The shredding mechanism includes an L-shaped connecting plate, a drive motor, a cutter shaft, and several cutter discs. The drive motor is connected to the support plate via the L-shaped connecting plate. The cutter shaft is disposed within the receiving frame, and rotating columns are provided at both ends of the cutter shaft. The drive motor is driven to one end of the cutter shaft via one of the rotating columns, and the other end of the cutter shaft is rotatably connected to the receiving frame via another rotating column. Each cutter disc is evenly disposed on the cutter shaft. The cutter discs in the two shredding mechanisms are staggered.

[0009] Each locking mechanism is correspondingly mounted on an L-shaped connecting plate and sleeved on a rotating column; the locking mechanism includes a connecting base plate, an annular connecting plate, a rotating ring, a receiving ring, three locking components, and two driving components; the outer wall of the annular connecting plate is connected to the L-shaped connecting plate through the connecting base plate; an annular rotating groove is formed on the inner wall of the annular connecting plate, the rotating ring is adapted to the annular rotating groove, and the outer edge of the rotating ring is inserted into the annular rotating groove and rotatably connected to the annular connecting plate; the receiving ring and the rotating ring are concentric rings, and the receiving ring is connected to the rotating ring; three through holes are evenly formed on the side wall of the receiving ring;

[0010] Each locking component is correspondingly disposed at one of the through-holes; the locking component includes a rotating rod, a driving connecting rod, a clamping block, and a sliding sleeve; the driving connecting rod is rotatably connected to the annular connecting plate through the rotating rod; each driving connecting rod passes through one of the through-holes, and the end of the driving connecting rod away from the rotating rod is connected to the clamping block; the sliding sleeve is adapted to the driving connecting rod, and the sliding sleeve is sleeved on the driving connecting rod and slidably connected to the driving connecting rod; each sliding sleeve is inserted into one of the through-holes, and a rotating connecting rod is disposed in the middle area of ​​the top of the sliding sleeve, and the sliding sleeve is rotatably connected to the receiving ring through the rotating connecting rod;

[0011] Both drive components are mounted on the receiving ring. Each drive component includes a drive column, a rotating handle, a threaded rod, and an extrusion plate. One end of the drive column is connected to the side wall of the receiving ring. The drive column has a threaded hole that is adapted to the threaded rod. The threaded rod is inserted into the threaded hole and screwed to the drive column. The end of the threaded rod near the annular connecting plate is connected to the extrusion plate, and the end of the threaded rod away from the extrusion plate is connected to the rotating handle.

[0012] In one embodiment, a drive handle is provided at the end of the drive column away from the receiving ring.

[0013] In one embodiment, the drive handle and the drive column are integrally formed.

[0014] In one embodiment, the drive handle is a circular plate-shaped structure.

[0015] In one embodiment, the drive column is a cylindrical structure.

[0020] In one embodiment, the anti-slip mat is a soft plastic mat.

[0021] In operation, the aforementioned dual-shaft shredder for magnesium alloy scrap works in conjunction with its two shredding mechanisms. Specifically, the drive motor drives each cutter disc to rotate via the cutter shaft, and the cutter discs in the two shredding mechanisms are staggered to shred the magnesium alloy scrap. When the dual-shaft shredder stops working, the rotating column is locked in place by a locking mechanism. Specifically, the drive column drives the receiving ring, which in turn drives the rotating ring to rotate along the annular rotating groove. During this process, one end of the drive connecting rod is rotatably connected to the annular connecting plate via the rotating rod. Simultaneously, a sliding sleeve is fitted onto the drive connecting rod and slidably connected to it. The sliding sleeve is rotatably connected to the receiving ring via the rotating connecting rod. As the drive connecting rod rotates, it drives the clamping block and two other clamping blocks to move closer together, pressing and locking the rotating column. After the rotating column is locked, the threaded rod is rotated by turning the handle. During the rotation of the threaded rod, the pressing plate moves closer to the annular connecting plate and abuts against it, thereby fixing the relative position of the drive column and the annular connecting plate, thus securing the locked state of the rotating column. The aforementioned dual-shaft shredder for magnesium alloy scrap can be locked when not in operation, thus avoiding safety hazards. Attached Figure Description

[0032] Please refer to the following: Figures 1 to 5 This utility model provides a dual-shaft shredder 10 for magnesium alloy scrap, which includes: a support frame 100, a receiving frame 200, two shredding mechanisms 300 and two locking mechanisms 400.

[0033] The support frame 100 includes a support plate 110 and several support columns 120, with each support column 120 evenly distributed along the edge of the support plate 110. A discharge port (not shown in the figure) is provided in the middle area of ​​the support plate 110.

[0034] The receiving frame 200 is located at the discharge port and connected to the support frame 100. Two shredding mechanisms 300 are respectively located on both sides of the receiving frame 200 and connected to the support frame 100.

[0035] The shredding mechanism 300 includes an L-shaped connecting plate 310, a drive motor 320, a cutter shaft 330, and several cutter discs 340.

[0036] Each locking mechanism 400 is correspondingly mounted on an L-shaped connecting plate 310 and sleeved on a rotating column 331. The locking mechanism 400 includes a connecting base plate 410, an annular connecting plate 420, a rotating ring 430, a receiving ring 440, three locking assemblies 450, and two drive assemblies 460. The outer wall of the annular connecting plate 420 is connected to the L-shaped connecting plate 310 via the connecting base plate 410. An annular rotating groove (not shown in the figure) is formed on the inner wall of the annular connecting plate 420. The rotating ring 430 is adapted to the annular rotating groove, and its outer edge is inserted into the annular rotating groove and rotatably connected to the annular connecting plate 420. The receiving ring 440 and the rotating ring 430 are concentric rings and are connected to each other. Three through holes 401 are evenly formed on the side wall of the receiving ring 440.

[0037] Each locking assembly 450 is correspondingly disposed at a through-hole 401. The locking assembly 450 includes a rotating rod 451, a driving connecting rod 452, a clamping block 453, and a sliding sleeve 454. The driving connecting rod 452 is rotatably connected to the annular connecting plate 420 via the rotating rod 451. Each driving connecting rod 452 passes through a through-hole 401, and the end of the driving connecting rod away from the rotating rod 451 is connected to the clamping block 453. In this embodiment, the clamping block 453 has a cylindrical structure. The sliding sleeve 454 is adapted to the driving connecting rod 452, and the sliding sleeve 454 is sleeved on the driving connecting rod 452 and slidably connected to it. Each sliding sleeve 454 is inserted into a through-hole 401, and a rotating connecting rod 455 is disposed in the middle region of the top of the sliding sleeve 454. The sliding sleeve 454 is rotatably connected to the receiving ring 440 via the rotating connecting rod 455. In one embodiment, an anti-slip sleeve (not shown in the figure) is provided on the outer wall of the clamping block 453, which can increase the anti-slip performance of the clamping block 453.

[0038] Both drive components 460 are mounted on the receiving ring 440. Each drive component 460 includes a drive column 461, a rotating handle 462, a threaded rod 463, and an extrusion plate 464. In this embodiment, the drive column 461 is a cylindrical structure. One end of the drive column 461 is connected to the side wall of the receiving ring 440. A threaded hole 402 is provided on the drive column 461, which is adapted to the threaded rod 463. The threaded rod 463 is inserted into the threaded hole 402 and screwed onto the drive column 461. The end of the threaded rod 463 near the annular connecting plate 420 is connected to the extrusion plate 464, and the end of the threaded rod 463 away from the extrusion plate 464 is connected to the rotating handle 462. To facilitate gripping the drive column 461, in one embodiment, a drive handle 465 is provided at the end of the drive column 461 away from the receiving ring 440. In this embodiment, the drive handle 465 is integrally formed with the drive column 461. This allows for easy gripping and force application of the drive column 461 via the drive handle 465. The drive handle 465 has a circular plate-like structure.

[0039] To increase the friction between the extrusion plate 464 and the annular connecting plate 420, in one embodiment, an anti-slip pad (not shown) is provided on the side of the extrusion plate 464 facing away from the threaded rod 463. In this embodiment, the anti-slip pad is a soft rubber pad. The soft rubber pad has a certain elasticity, good toughness, and excellent anti-slip performance. It can increase the friction between the extrusion plate 464 and the annular connecting plate 420 while protecting the annular connecting plate 464. In another embodiment, the anti-slip pad is a soft silicone pad. In yet another embodiment, the anti-slip pad is a soft plastic pad. Thus, the anti-slip pad provided on the side of the extrusion plate 464 facing away from the threaded rod 463 can increase the friction between the extrusion plate 464 and the annular connecting plate 420.

[0040] During operation, the aforementioned dual-shaft shredder 10 for magnesium alloy scrap involves two shredding mechanisms 300 working together. Specifically, the drive motor 320 drives each cutter disc 340 to rotate via the cutter shaft 330, and the cutter discs 340 in the two shredding mechanisms 300 are staggered to shred the magnesium alloy scrap. When the aforementioned dual-shaft shredder 10 for magnesium alloy scrap stops working, the rotating column 331 is locked and fixed by the locking mechanism 400. Specifically, the drive column 461 drives the receiving ring 440 to drive the rotating ring 430 to rotate along the annular rotating groove. During this process, one end of the drive connecting rod 452 is rotatably connected to the annular connecting plate 420 via the rotating rod 451. At the same time, the sliding sleeve 454 is sleeved on the drive connecting rod 452 and slidably connected to the drive connecting rod 452. The sliding sleeve 454 is rotatably connected to the receiving ring 440 via the rotating connecting rod 455. While driving the connecting rod 452 to rotate, it drives the clamping block 453 and the other two clamping blocks 453 to move closer together and press and lock the rotating column 331. After the rotating column 331 is locked, the threaded rod 463 is driven to rotate by rotating the handle 462. During the rotation of the threaded rod 463, the pressing plate 464 moves closer to the annular connecting plate 420 and abuts against the annular connecting plate 420, thereby fixing the relative position of the driving column 461 and the annular connecting plate 420, and thus fixing the locked state of the rotating column 331. The above-mentioned magnesium alloy scrap bi-shaft shredder 10 can lock the shredder when it is not in operation, avoiding safety hazards.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
