Description

Technical Field

[0001] This invention relates to the field of rare earth processing and magnetic material manufacturing, and in particular to a praseodymium-neodymium cutting and shredding machine and its cutting method. Background Technology

[0002] Praseodymium-neodymium cutting machines are specialized devices for cutting praseodymium and neodymium, widely used in rare earth processing and magnetic material manufacturing. Currently, most praseodymium-neodymium cutting machines on the market use rebar cutting machines or other general-purpose equipment instead of dedicated machines. Because these machines are not specifically designed for praseodymium and neodymium, their blade size is too small, requiring multiple rotations to achieve the desired size, resulting in low efficiency and inconsistent material sizes, affecting subsequent processing quality and efficiency.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0009] In a preferred embodiment, the cutting scissors further include a blade connecting member, which is disposed between the lower parts of the first movable cutting scissors and the second movable cutting scissors; wherein the movement direction of the first hydraulic cylinder of the first movable cutting scissors is opposite to and synchronized with the movement direction of the second movable cutting scissors and the second hydraulic cylinder, that is, when the first hydraulic cylinder extends, the second hydraulic cylinder retracts.

[0010] In a preferred embodiment, the shredding mechanism includes a shredding structure, a first shredding motor and a reduction gear, a second shredding motor and a reduction gear, a first shredding blade, and a second shredding blade. The shredding structure is disposed below the cutting structure and is in the shape of a rectangular barrel with its upper and lower openings connected through each other. The upper opening of the shredding structure is aligned with the lower opening of the cutting structure. The first shredding motor and the reduction gear, and the second shredding motor and the reduction gear, are respectively disposed on the outer sides of opposite wall panels of the rectangular barrel structure.

[0011] In a preferred embodiment, the first shredder and the second shredder rotate in opposite directions, and the praseodymium-neodymium block cut by the cutting mechanism falls between the first shredder and the second shredder and is shredded to the designed size.

[0012] In a preferred embodiment, the axial distance between the first shredding blade and the second shredding blade can be finely adjusted.

[0013] In a preferred embodiment, the praseodymium-neodymium cutting and shredding machine further includes a cleaning mechanism, which is disposed at the wall panel of the shredding structure where the first shredding motor and the second shredding motor are not installed. The cleaning mechanism includes a first cleaning blade and a second cleaning blade, which are symmetrically disposed on the inner sides of two opposing wall panels of the square barrel structure. Both the first cleaning blade and the second cleaning blade include multiple cleaning blades, and the front end of each cleaning blade extends into the space between the multiple shredding blades of the first shredding blade and the second shredding blade.

[0014] To achieve the aforementioned other objective, a cutting method for a praseodymium-neodymium cutting and shredding machine is provided, which is applied to the aforementioned praseodymium-neodymium cutting and shredding machine. The cutting method includes: praseodymium-neodymium blocks of a certain size to be cut are transferred from the previous stage to the discharge hopper of the discharge mechanism via the conveyor belt of the feeding mechanism; the praseodymium-neodymium blocks to be cut fall from the lower outlet of the discharge hopper into the upper cutting cutter hole of the upper fixed cutting blade body, and the lower end of the praseodymium-neodymium blocks to be cut falls exactly into the movable cutting cutter hole of the movable cutting blade body. At this time, the top surface of the lower fixed cutting blade body abuts against the lower opening of the movable cutting cutter hole and supports the lower end of the praseodymium-neodymium block to be cut. Both the first and second hydraulic cylinders move in the same direction, simultaneously driving the first and second movable cutting shears to move horizontally in the same direction. The front ends of the first and second movable cutting shears are spaced a distance greater than the size of the upper cutting shear hole. A shearing surface is formed between the top surfaces of the first and second movable cutting shears and the bottom surface of the upper cutting shear hole. When the first movable cutting shear reaches the upper cutting shear hole, it cuts off a piece from the lower end of the praseodymium-neodymium block and pushes it into the shredding mechanism below. When the two hydraulic cylinders move in opposite directions simultaneously, as the end of the first movable cutting shear leaves the upper cutting shear hole, the praseodymium-neodymium block to be cut in the upper cutting shear hole continues to fall onto the top surface of the lower fixed cutting shear body. At this moment, the end of the second movable cutting shear reaches the upper cutting shear hole, cutting off a piece from the lower end of the praseodymium-neodymium block and pushing it into the shredding mechanism below. After multiple reciprocating horizontal movements and cutting by the first and second movable cutting shears, one piece of praseodymium-neodymium block is cut, and a second piece falls into the upper cutting shear hole. The praseodymium-neodymium block cut by the cutting mechanism... Neodymium blocks fall sequentially into the shredding mechanism; the first and second shredding motors and reducers of the shredding mechanism simultaneously drive the first and second shredding blades to rotate in opposite directions, further shredding the praseodymium-neodymium blocks cut by the cutting mechanism into smaller designed sizes; the first and second cleaning blades of the cleaning mechanism can remove the praseodymium-neodymium blocks stuck or adhered between multiple cleaning blades; and finally, the praseodymium-neodymium blocks shredded into qualified sizes fall from the shredding mechanism onto the discharge conveyor belt of the discharge mechanism and are transported to the next stage.

[0015] In a preferred embodiment, the cutting method of the praseodymium-neodymium cutting and shredding machine further includes: repeating the aforementioned actions multiple times until a complete praseodymium-neodymium block is cut and shredded to a qualified size, and then the feeding mechanism transports the next complete praseodymium-neodymium block to be cut into the discharge hopper and begins the next round of cutting and shredding.

[0016] Compared with the prior art, the praseodymium-neodymium cutting and shredding machine and its cutting method according to the present invention have the following beneficial effects: The present application can automatically cut the praseodymium-neodymium blocks to be cut into the designed specifications and sizes through the sequentially arranged cutting and shredding mechanisms, ensuring accurate dimensions and saving labor; furthermore, the present application utilizes the self-weight of the praseodymium-neodymium blocks to be cut to achieve the connection between the cutting and shredding mechanisms, making the structure simple and the manufacturing cost low; the present application can smoothly connect with upstream and downstream production lines through the feeding structure, unloading mechanism, and discharge mechanism, greatly improving work efficiency and reducing labor costs for material transfer; simultaneously, the cleaning mechanism provided in the present application can thoroughly clean the praseodymium-neodymium blocks stuck or adhered to the shredding blades, making the operation of the mechanism smoother and greatly reducing operating and maintenance costs; in addition, the present application can also adapt to the cutting of praseodymium-neodymium blocks of various sizes and specifications by adjusting the specifications of the upper cutting shear hole, the specifications of the two shredding blades, and the blade circumference distance, which can be widely promoted within the industry.

[0028] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0029] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0030] like Figures 1 to 3 As shown, a praseodymium-neodymium cutting and shredding machine according to a preferred embodiment of the present invention includes a feeding mechanism 10, a discharging mechanism 20, a cutting mechanism 30, a shredding mechanism 40, a cleaning mechanism 50, and a discharge mechanism 60. These mechanisms are arranged in a basically stacked manner, and the connection and conversion between components are mainly achieved by utilizing the weight of the praseodymium-neodymium blocks to be cut. The feeding mechanism 10 is used to transport the praseodymium-neodymium blocks to be cut; the discharging mechanism 20 is located below the feeding mechanism 10, through which the praseodymium-neodymium blocks to be cut are transported to the discharging mechanism 20; the cutting mechanism 30 is located below the discharging mechanism 20, through which the praseodymium-neodymium blocks to be cut are cut into smaller praseodymium-neodymium blocks; the shredding mechanism 40 is located below the cutting mechanism 30, through which the praseodymium-neodymium blocks cut by the cutting mechanism 30 are shredded. The praseodymium-neodymium blocks are shredded into acceptable sizes by the shredding mechanism 40; the cleaning mechanism 50 is located at the shredding mechanism 40, and the cleaning mechanism 50 can clean out the praseodymium-neodymium blocks that have been shredded into acceptable sizes by the shredding mechanism 40 and are stuck there; the discharge mechanism 60 is located below the shredding mechanism 40, and the praseodymium-neodymium blocks shredded by the shredding mechanism 40 fall onto the discharge conveyor belt of the discharge mechanism 60 and are transported to the next stage.

[0031] like Figures 4 to 6As shown, in some embodiments, the cutting mechanism 30 includes a cutting structure 303, a first hydraulic cylinder 301, a second hydraulic cylinder 302, and a cutting shear body 304; the cutting structure 303 has a square barrel shape and is open at both the top and bottom (the square barrel shape is only an example of this embodiment, and the present invention is not limited thereto); the first hydraulic cylinder 301 is disposed on a wall panel on one side of the cutting structure 303, and the axis of the first hydraulic cylinder 301 is perpendicular to the wall panel; the second hydraulic cylinder 302 is disposed on a wall panel opposite to the first hydraulic cylinder 301, and the axis of the second hydraulic cylinder 302 is perpendicular to the wall panel, preferably the axis of the first hydraulic cylinder 301 and the axis of the second hydraulic cylinder 302 are coaxially arranged; the cutting shear body 304 is disposed between two wall panels without hydraulic cylinders, and an upper cutting shear hole 3042 is provided in the middle of the top of the cutting shear body 304, which is directly opposite the discharge hole at the bottom of the hopper 201.

[0032] Please see Figures 4 to 6 In some embodiments, the cutting shear body 304 includes an upper fixed cutting shear body 3041, a lower fixed cutting shear body 305, and a movable cutting shear body. The upper fixed cutting shear body 3041 is disposed at the upper part of the cutting shear body 304 and located at the upper part between two wall panels without hydraulic cylinders. An upper cutting shear hole 3042 is disposed at the middle of the upper fixed cutting shear body 3041 and extends through the upper and lower surfaces of the upper fixed cutting shear body 3041. An upper cutting shear tool is disposed at the lower surface of the upper fixed cutting shear body 3041 and located on both sides of the upper cutting shear hole 3042 adjacent to the sides where hydraulic cylinders are disposed. The lower fixed cutting shear body 305 is disposed at the lower part of the cutting shear body 304 and located at the lower part between the two wall panels without hydraulic cylinders. The movable cutting shear body is disposed at the upper fixed cutting shear body 3041. Between the bottom surface of the upper fixed cutting shear body 3041 and the top surface of the lower fixed cutting shear body 305, the movable cutting shear body includes a first movable cutting shear 3043 and a second movable cutting shear 3044; one end of the first movable cutting shear 3043 is connected to the first hydraulic cylinder 301 and can reciprocate horizontally with the extension and retraction of the first hydraulic cylinder 301; one end of the second movable cutting shear 3044 is connected to the second hydraulic cylinder 302 and can reciprocate horizontally with the extension and retraction of the second hydraulic cylinder 302; wherein the first movable cutting shear 3043 and the second movable cutting shear 3044 are located between the bottom surface of the upper fixed cutting shear body 3041 and the top surface of the lower fixed cutting shear body 305, and the top surfaces of the first movable cutting shear 3043 and the second movable cutting shear 3044 are installed close to the bottom surface of the upper fixed cutting shear body 3041 and form a cutting surface.

[0033] In some embodiments, the distance between the upper fixed cutting shear body 3041 and the lower fixed cutting shear body 305 can be adjusted, and this distance can determine the thickness of the praseodymium-neodymium block to be cut. The distance between the bottom surface of the upper fixed cutting shear body 3041 and the top surface of the lower fixed cutting shear body 305 is greater than the thickness of the first movable cutting shear 3043 and the second movable cutting shear 3044.

[0034] Please see Figures 5 to 6 In some embodiments, the cutting shears 304 further includes a blade connecting member 306, which is disposed between the lower parts of the first movable cutting shears 3043 and the second movable cutting shears 3044; wherein the movement direction of the first hydraulic cylinder 301 of the first movable cutting shears 3043 is opposite to and synchronized with the movement direction of the second movable cutting shears 3044 and the second hydraulic cylinder 302, that is, when the first hydraulic cylinder 301 extends, the second hydraulic cylinder 302 retracts.

[0035] Please see Figures 5 to 6 In some embodiments, the blades of the first movable cutting blade 3043 and the second movable cutting blade 3044 are spaced apart by a distance. This distance is mainly used so that the cut praseodymium-neodymium blocks can be pushed away from the top surface of the lower fixed cutting blade body 305 by the first movable cutting blade 3043 or the second movable cutting blade 3044 and fall into the shredding mechanism 40. It is also used so that when the blades of the first movable cutting blade 3043 or the second movable cutting blade 3044 leave the upper cutting blade hole 3042 and before the blades of the first movable cutting blade 3043 or the second movable cutting blade 3044 reach the upper cutting blade hole 3042, the cut praseodymium-neodymium blocks can fall down from the upper cutting blade hole 3042 to the top surface of the lower fixed cutting blade body 305.

[0036] In some embodiments, the first movable cutting shear 3043 and the second movable cutting shear 3044 can also be configured as an integral structure. A lower cutting shear hole (not shown) is provided between the first movable cutting shear 3043 and the second movable cutting shear 3044. The size of the lower cutting shear hole can be slightly larger than that of the upper cutting shear hole 3042. Each time the lower cutting shear hole moves to align with the upper cutting shear hole 3042, it pauses briefly, waiting for the praseodymium-neodymium block to be cut to fall down before moving again, thus completing the cutting. When the lower cutting shear hole leaves the top surface area of ​​the lower fixed cutting shear body 305, the praseodymium-neodymium block to be cut falls from the lower cutting shear hole into the shredding mechanism. The reverse movement is the same: the lower cutting shear hole moves to align with the upper cutting shear hole 3042, pauses briefly, waiting for the praseodymium-neodymium block to be cut to fall down before moving again, thus completing the cutting.

[0037] like Figures 7 to 8As shown, in some embodiments, the shredding mechanism 40 includes a shredding structure 403, a first shredding motor 401 and a reduction gear, a second shredding motor 402 and a reduction gear, a first shredding blade 4041 and a second shredding blade 4042; the shredding structure 403 is disposed below the cutting structure 303, and the shredding structure 403 has a rectangular barrel shape with its upper and lower openings connected through each other (the rectangular barrel shape is only an example of this embodiment, and the present invention is not limited thereto), and the upper opening of the shredding structure 403 is aligned and connected with the lower opening of the cutting structure 303; the first shredding motor 402... The first shredder 4041 and the second shredder 4042 are respectively installed on the outer sides of the opposite wall panels of the square barrel structure; the first shredder 4041 and the second shredder 4042 are installed between the wall panels on which the first shredder 401 and the second shredder 402 and the second shredder 4042 are installed, with the axis of the first shredder 4041 and the axis of the second shredder 4042 being parallel; wherein the first shredder 4041 is connected to the reduction device of the first shredder 401, and the second shredder 4042 is connected to the reduction device of the second shredder 402.

[0038] In some embodiments, the first shredding blade 4041 and the second shredding blade 4042 rotate in opposite directions and move towards each other. The praseodymium-neodymium block cut by the cutting mechanism 30 falls between the first shredding blade 4041 and the second shredding blade 4042 and is shredded to the designed size.

[0039] In some embodiments, the axial distance between the first shredding blade 4041 and the second shredding blade 4042 can be finely adjusted.

[0040] Please see Figures 7 to 8 In some embodiments, preferably, the first shredding blade 4041 and the second shredding blade 4042 are both composed of multiple coaxial and parallel blade discs (or blades), each blade including multiple serrated cutting edges. The cutting edges of the multiple blades of each shredding blade are generally arranged in a manner that is offset from each other by an angle. The first shredding blade 4041 and the second shredding blade 4042 are generally symmetrically arranged, which is more conducive to improving cutting efficiency.

[0041] like Figures 8 to 9As shown, in some embodiments, the praseodymium-neodymium cutting and shredding machine further includes a cleaning mechanism 50, which is disposed at the wall panel of the shredding structure 403 where the first shredding motor 401 and the second shredding motor 402 are not disposed. The cleaning mechanism 50 includes a first cleaning blade 501 and a second cleaning blade 502, which are symmetrically disposed on the inner sides of two opposing wall panels of the square barrel structure. The first cleaning blade 501 and the second cleaning blade 502 each include multiple cleaning blades, and the front end of each cleaning blade extends into the space between the multiple shredding blades of the first shredding blade 4041 and the second shredding blade 4042. The cleaning mechanism 50 is used to clean the praseodymium-neodymium blocks that are stuck or adhered between the multiple cleaning blades.

[0042] In some implementations, the number of cleaning blades matches the number of blades on each shredder, with each cleaning blade penetrating into the gap between two blades and its tip close to the outer circumference of the shredder's shaft. This facilitates the cleaning of praseodymium-neodymium blocks stuck or adhering to the shaft surface or the blade gaps.

[0043] To achieve the aforementioned other objective, a cutting method for a praseodymium-neodymium cutting and shredding machine is provided. This method, applied to the aforementioned praseodymium-neodymium cutting and shredding machine, includes: praseodymium-neodymium blocks of a certain size to be cut are transferred from the previous stage via the conveyor belt of the feeding mechanism 10 to the discharge hopper 201 of the discharge mechanism 20; the praseodymium-neodymium blocks to be cut fall from the lower outlet of the discharge hopper 201 into the upper cutting shear hole 3042 of the upper fixed cutting shear body 3041, with the lower end of the praseodymium-neodymium blocks falling precisely into the movable cutting shear hole of the movable cutting shear body. At this time, the top surface of the lower fixed cutting shear body 305 abuts against the lower opening of the movable cutting shear hole and supports the lower end of the praseodymium-neodymium block to be cut; a first hydraulic cylinder 301 and a second hydraulic cylinder 3045... Both move in the same direction, simultaneously driving the first movable cutting shear 3043 and the second movable cutting shear 3044 to move horizontally in the same direction; the front ends of the first movable cutting shear 3043 and the second movable cutting shear 3044 are separated by a distance greater than the size of the upper cutting shear hole 3042; a shearing surface is formed between the top surface of the first movable cutting shear 3043 and the second movable cutting shear 3044 and the bottom surface of the upper cutting shear hole 3042. When the first movable cutting shear 3043 moves to the upper cutting shear hole 3042, the first movable cutting shear 3043 cuts off a piece from the lower end of the praseodymium-neodymium block to be cut and pushes it into the shredding mechanism 40 below; when the first hydraulic cylinder 301 and the second hydraulic cylinder... When the hydraulic cylinder 302 moves in opposite directions, as the end of the first movable cutting shear 3043 leaves the upper cutting shear hole 3042, the praseodymium-neodymium block to be cut in the upper cutting shear hole 3042 continues to fall onto the top surface of the lower fixed cutting shear body 305. At this moment, the end of the second movable cutting shear 3044 moves to the upper cutting shear hole 3042, cutting off a piece of the lower end of the praseodymium-neodymium block and pushing it into the shredding mechanism 40 below. After multiple reciprocating horizontal movements and cutting by the first movable cutting shear 3043 and the second movable cutting shear 3044, one piece of praseodymium-neodymium block to be cut is finished, and a second piece falls into the upper cutting shear hole 3042. The praseodymium-neodymium block cut by the cutting mechanism 30... Neodymium blocks fall sequentially into the shredding mechanism 40; the first shredding motor 401 and reducer and the second shredding motor 402 and reducer of the shredding mechanism 40 simultaneously drive the first shredding blade 4041 and the second shredding blade 4042 to rotate in opposite directions, further shredding the praseodymium-neodymium blocks cut by the cutting mechanism 30 onto the first shredding blade 4041 and the second shredding blade 4042 into smaller designed sizes; the first cleaning blade 501 of the cleaning mechanism 50 can remove the praseodymium-neodymium blocks stuck or stuck between multiple cleaning blades; and finally, the praseodymium-neodymium blocks shredded into qualified sizes fall from the shredding mechanism 40 onto the discharge conveyor belt of the discharge mechanism 60 and are transported to the next stage.

[0044] In some embodiments, the cutting method of the praseodymium-neodymium cutting and shredding machine further includes: repeating the aforementioned actions multiple times until a complete praseodymium-neodymium block is cut and shredded to a qualified size, and then the feeding mechanism 10 transports the next complete praseodymium-neodymium block to be cut into the discharge hopper 201 and begins the next round of cutting and shredding.

[0045] In summary, the praseodymium-neodymium cutting and shredding machine and its cutting method according to the present invention have the following advantages: The present application, through the sequentially arranged cutting and shredding mechanisms, can automatically cut the praseodymium-neodymium blocks to be cut into the designed specifications, ensuring accurate dimensions and saving labor. Furthermore, the present application utilizes the weight of the praseodymium-neodymium blocks to be cut to connect the cutting and shredding mechanisms, resulting in a simple structure and low manufacturing cost. The present application, through its feeding structure, unloading mechanism, and discharge mechanism, can seamlessly connect with upstream and downstream production lines, significantly improving work efficiency and reducing labor costs associated with material handling. Simultaneously, the cleaning mechanism provided in the present application can thoroughly clean praseodymium-neodymium blocks stuck or adhered to the shredding blades, making the operation of the mechanism smoother and greatly reducing operating and maintenance costs. In addition, the present application can adapt to the cutting of praseodymium-neodymium blocks of various sizes by adjusting the specifications of the upper cutting shear hole, the specifications of the two shredding blades, and the blade circumferential distance, allowing for widespread adoption within the industry.

The praseodymium-neodymium block to be cut falls from the lower outlet of the hopper into the upper cutting hole of the upper fixed cutting blade body. The lower end of the praseodymium-neodymium block to be cut falls into the movable cutting blade opening of the movable cutting blade body. At this time, the top surface of the lower fixed cutting blade body abuts against the lower opening of the movable cutting blade opening and supports the lower end of the praseodymium-neodymium block to be cut. Both the first hydraulic cylinder and the second hydraulic cylinder move in the same direction, simultaneously driving the first movable cutting shear and the second movable cutting shear to move horizontally in the same direction. The front ends of the first and second movable cutting shears are separated by a distance, which is greater than the size of the upper cutting shear hole. The top surfaces of the first and second movable cutting shears form a shearing surface with the bottom surface of the upper cutting shear hole. When the first movable cutting shear moves to the upper cutting shear hole, it cuts off a piece of the lower end of the praseodymium-neodymium block and pushes it into the shredding mechanism below. When the first and second hydraulic cylinders move in opposite directions simultaneously, as the end of the first movable cutting shear leaves the upper cutting shear hole, the praseodymium-neodymium block located in the upper cutting shear hole continues to fall onto the top surface of the lower fixed cutting shear body. At this time, the end of the second movable cutting shear moves to the upper cutting shear hole, cuts off a piece of the lower end of the praseodymium-neodymium block again, and pushes it into the shredding mechanism below. After multiple reciprocating horizontal movements and cutting by the first and second movable cutting shears, one piece of praseodymium-neodymium block is cut off, and a second piece falls into the upper cutting shear hole. The praseodymium-neodymium blocks cut by the cutting mechanism all fall sequentially into the shredding mechanism; The first shredding motor and reducer and the second shredding motor and reducer of the shredding mechanism simultaneously drive the first shredding blade and the second shredding blade to rotate in opposite directions, further shredding the praseodymium and neodymium blocks that have been cut by the cutting mechanism and fall onto the first shredding blade and the second shredding blade into smaller design sizes; The first cleaning blade of the cleaning mechanism is capable of removing praseodymium-neodymium blocks that are stuck or adhered between the multiple cleaning blades; and Finally, the praseodymium-neodymium blocks, which are shredded into qualified sizes, fall from the shredding mechanism onto the discharge conveyor belt of the discharge mechanism and are transported to the next stage.
