Description

Technical Field

[0001] This application relates to the technical field of magnetic material production, and in particular to a magnetic material crushing device. Background Technology

[0002] Magnetic materials are substances that generate magnetism by combining iron, cobalt, nickel and their alloys, and are mainly used in modern industry, electronics and medical fields.

[0003] When crushing existing magnetic materials, operators typically place the magnetic material into the crushing chamber and use high-speed rotating blades to shear and crush it.

[0004] When magnetic materials are crushed, the centrifugal force of the blades causes the magnetic materials to make regular circular motions in the crushing chamber, thus forming a fixed motion trajectory. This results in insufficient crushing of the magnetic materials by the blades and low crushing efficiency. Summary of the Invention

[0005] In order to improve the crushing efficiency of magnetic material crushing devices, this application provides a magnetic material crushing device.

[0006] This application provides a magnetic material crushing device, which adopts the following technical solution: A magnetic material crushing device includes a crushing barrel, a crushing assembly, a pushing assembly, a transmission assembly, and a motor. The crushing barrel is vertically arranged and has a feed pipe at its top. A discharge port is located at the bottom of the crushing barrel. The crushing assembly is disposed within the crushing barrel and is used to crush the magnetic material. The crushing assembly includes a primary crushing section and a secondary crushing section. The primary crushing section is located at the top of the crushing barrel and is used for initial crushing of the magnetic material. The secondary crushing section is located at the bottom of the crushing barrel and is arranged in multiple sets along the vertical direction, used for secondary crushing of the magnetic material. The pushing assembly is disposed within the crushing barrel and is used to push the magnetic material to move within the crushing barrel. The transmission assembly is disposed at the bottom of the crushing barrel and is used to drive the pushing assembly. The motor is vertically disposed at the bottom of the crushing barrel and is used to drive the crushing assembly and the transmission assembly.

[0007] By adopting the above technical solution, when crushing magnetic materials, the operator pours the magnetic material into the crushing barrel through the feed pipe. The motor drives the crushing components to work. The primary crushing section initially crushes the magnetic material, and the secondary crushing section further crushes the initially crushed magnetic material. The operator collects the secondary crushed magnetic material through the discharge port. During the crushing process, the transmission component drives the pushing component to move the magnetic material in the crushing barrel, making it difficult for the magnetic material to form a fixed movement trajectory in the crushing barrel, thereby improving the crushing efficiency of the crushing components on the magnetic material.

[0008] Optionally, the primary crushing section includes a rotating shaft, a first crushing roller, a second crushing roller, and a driven shaft; the rotating shaft is coaxially and fixedly connected to the output shaft of the motor; the first crushing roller is vertically arranged and coaxially and fixedly connected to the rotating shaft; the second crushing roller is vertically arranged and meshes with the first crushing roller, and multiple second crushing rollers are arranged circumferentially along the axis of the crushing barrel; the driven shaft is vertically arranged and coaxially and fixedly connected to the second crushing roller, and multiple driven shafts are arranged circumferentially along the axis of the crushing barrel, corresponding one-to-one with the second crushing rollers; the secondary crushing section includes a stirring rod and crushing blades; the stirring rod is horizontally arranged and fixedly connected to the rotating shaft, and multiple stirring rods are arranged circumferentially along the axis of the rotating shaft; the crushing blades are fixedly connected to the stirring rods, and multiple crushing blades are arranged circumferentially along the axis of the rotating shaft, with each of the multiple crushing blades corresponding one-to-one with the multiple stirring rods.

[0009] By adopting the above technical solution, when the magnetic material is crushed, the motor works, the motor drives the rotating shaft to rotate, the rotating shaft drives the first crushing roller to rotate, the first crushing roller meshes with the second crushing roller, so that the first crushing roller shears and crushes the magnetic material, thereby making the magnetic material initially crushed in the crushing barrel; when the magnetic material after initial crushing passes through the secondary crushing section, the rotating shaft drives the stirring rod to rotate, so that the crushing blades on the stirring rod further crush the magnetic material after initial crushing, thereby improving the crushing efficiency of the magnetic material crushing device through secondary crushing of the magnetic material.

[0010] Optionally, a filter assembly is provided inside the crushing barrel. The filter assembly includes a filter plate and a filter barrel. The filter plate is horizontally arranged and fixedly connected to the crushing barrel. The top end of the filter plate abuts against the bottom end of the first crushing roller. The filter barrel is vertically arranged inside the crushing barrel, and its top end is fixedly connected to the filter plate.

[0011] By adopting the above technical solution, when crushing magnetic materials, the smaller magnetic materials after initial crushing enter the filter barrel through the filter plate, while the larger magnetic materials continue to be crushed through the primary crushing section. After the smaller magnetic materials enter the filter barrel, the secondary crushing section crushes them again. When the crushing blades crush the magnetic materials, the magnetic materials generate centrifugal force under the action of the crushing blades, causing the crushed magnetic materials that meet the usage requirements to be thrown out of the filter barrel. This makes it easy for operators to collect the crushed magnetic materials through the discharge port. The primary and secondary crushing sections in the crushing barrel are separated by the filter plate, thereby improving the crushing efficiency of the magnetic material crushing device.

[0012] Optionally, the pushing assembly includes a pushing plate, which is vertically disposed inside the filter barrel and hinged to the filter barrel; the transmission assembly is disposed on one side of the pushing plate and is used to drive the pushing plate to rotate.

[0013] By adopting the above technical solution, when the magnetic material in the filter barrel is crushed, the transmission component drives the pusher plate to rotate, and the pusher plate pushes the magnetic material in the filter barrel, making it difficult for the magnetic material to form a fixed movement trajectory in the filter barrel; the rotation of the pusher plate improves the crushing efficiency of the crushing blade.

[0014] Optionally, the transmission assembly includes a first telescopic rod; the first telescopic rod is horizontally disposed on one side of the crushing barrel and fixedly connected to the crushing barrel, and the first telescopic rod is used to drive the pusher plate to rotate.

[0015] By adopting the above technical solution, when the movable end of the first telescopic rod extends, the movable end of the first telescopic rod drives the pusher plate to rotate inside the filter barrel; this allows the operator to easily change the movement trajectory of the magnetic material inside the filter barrel by controlling the first telescopic rod, thereby improving the crushing efficiency of the crushing blade.

[0016] Optionally, the transmission assembly further includes a second telescopic rod and a connecting pipe; the second telescopic rod is horizontally disposed at the bottom of the crushing barrel and fixedly connected to the crushing barrel; the movable end of the first telescopic rod divides the fixed end of the first telescopic rod into a first rod-side chamber and a first rodless chamber, the first rodless chamber being filled with liquid; the movable end of the second telescopic rod divides the fixed end of the second telescopic rod into a second rod-side chamber and a second rodless chamber, the second rodless chamber being filled with liquid; one end of the connecting pipe communicates with the first rodless chamber and the other end communicates with the second rodless chamber; a cam is disposed at the bottom of the crushing barrel, the cam is fixedly connected to the output shaft of the motor and abuts against the movable end of the second telescopic rod; a spring is horizontally disposed on the side of the pusher plate near the filter barrel, the two ends of the spring being fixedly connected to the filter barrel and the pusher plate respectively.

[0017] By adopting the above technical solution, when the motor is working, the output shaft of the motor drives the cam to rotate. When the cam rotates, it squeezes the movable end of the second telescopic rod, causing the movable end of the second telescopic rod to contract. When the movable end of the second telescopic rod contracts, the volume of the second rodless cavity decreases, and the liquid in the second rodless cavity flows to the first rodless cavity through the connecting pipe, increasing the volume of the first rodless cavity. This causes the movable end of the first telescopic rod to extend, pushing the pusher plate to rotate, and the spring is in a stretched state. When the tip of the cam rotates away from the movable end of the first telescopic rod, the spring returns to its original position, and the pusher plate drives the movable end of the first telescopic rod to contract. The volume of the rodless cavity of the first telescopic rod decreases, and the liquid in the first rodless cavity flows to the second rodless cavity through the connecting pipe, causing the movable end of the second telescopic rod to return to its original position. Thus, when the motor is working, the pusher plate rotates synchronously.

[0018] Optionally, the pushing assembly further includes a connecting plate and a driving rod. The connecting plate is vertically disposed on the side of the crushing barrel near the first telescopic rod and is fixedly connected to the movable end of the first telescopic rod. The driving rod is horizontally disposed on the side of the pushing plate near the connecting plate and is fixedly connected to the connecting plate. The side of the driving rod away from the connecting plate abuts against the pushing plate. Multiple pushing plates are disposed vertically and spaced apart from the secondary crushing section. Multiple springs are disposed vertically and correspond one-to-one with the pushing plates. Multiple driving rods are disposed vertically and correspond one-to-one with the pushing plates.

[0019] By adopting the above technical solution, when the movable end of the first telescopic rod extends, the movable end of the first telescopic rod drives the connecting plate to move, the connecting plate drives the drive rod to move, and the drive rod pushes the pusher plate to rotate inside the filter barrel, making it difficult for the magnetic material inside the filter barrel to form a fixed motion trajectory, thereby improving the crushing efficiency of the crushing blade.

[0020] Optionally, multiple sets of the pushing assembly and the transmission assembly are provided and arranged along the circumference of the crushing barrel.

[0021] By adopting the above technical solution, when the magnetic material is crushed, multiple sets of pushing components push the magnetic material in the filter barrel in multiple directions, thereby improving the crushing efficiency of the crushing blades.

[0022] Optionally, a first gear is fixedly connected to the rotating shaft, and the first gear is located at the top of the crushing barrel; a second gear is fixedly connected to the driven shaft, and the second gear is located at the top of the crushing barrel and meshes with the first gear. Multiple second gears are arranged circumferentially along the axis of the crushing barrel and correspond one-to-one with the driven shaft.

[0023] By adopting the above technical solution, when the motor is working, the output shaft of the motor drives the rotating shaft to rotate, the rotating shaft drives the first gear to rotate, the first gear drives the second gear to rotate, the second gear drives the driven shaft to rotate, and the driven shaft drives the second crushing roller to rotate, so that the first crushing roller and the second crushing roller rotate synchronously, thereby improving the crushing efficiency.

[0024] In summary, this application includes at least one of the following beneficial technical effects: By setting up a primary crushing section and a secondary crushing section, the magnetic material is initially crushed in the primary crushing section and then further crushed in the secondary crushing section, thus improving the crushing efficiency. By setting up a pusher assembly, when the magnetic material is broken, the pusher plate rotates, making it difficult for the magnetic material to form a fixed movement trajectory inside the filter barrel. By setting up a transmission component, a motor, and a cam, when the motor is working, the output shaft of the motor drives the cam to rotate, the cam drives the transmission component to work, and the transmission component drives the pushing component to work, so that when the magnetic material is broken, the pushing component works synchronously.

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a magnetic material crushing device. (Refer to...)

[0029] When the magnetic material is crushed, the motor 6 drives the crushing component 2 and the transmission component 5 to work. The crushing component 2 crushes the magnetic material, and the transmission component 5 drives the pushing component 4 to push the magnetic material to move in the crushing barrel 1, so that the magnetic material is not easy to form a fixed movement trajectory. When the magnetic material is crushed, the filtering component 3 screens and filters the crushed magnetic material that meets the usage requirements, so that it is convenient for the operator to collect the crushed magnetic material.

[0032] Reference Figure 1 and Figure 2The crushing assembly 2 includes a primary crushing section 21 and a secondary crushing section 22. The primary crushing section 21 is located at the top of the crushing barrel 1 and is used for the initial crushing of magnetic materials. The primary crushing section 21 includes a rotating shaft 211, a first crushing roller 212, a second crushing roller 213, a driven shaft 214, a first gear 215, and a second gear 216. The rotating shaft 211 is coaxially and fixedly connected to the output shaft of the motor 6 and is vertically arranged. The first crushing roller 212 is vertically arranged and coaxially and fixedly connected to the rotating shaft 211. The second crushing roller 213 is vertically arranged and meshes with the first crushing roller 212. Multiple second crushing rollers 213 are arranged circumferentially along the axis of the crushing barrel 1. The driven shaft 214 is vertically arranged and fixedly connected to the second crushing roller 213. Multiple driven shafts 214 are arranged circumferentially along the axis of the crushing barrel 1 and correspond one-to-one with the second crushing roller 213.

[0033] Reference Figure 2 The secondary crushing section 22 is located at the bottom of the crushing barrel 1 and is arranged in multiple sets along the vertical direction. The secondary crushing section 22 is used for secondary crushing of magnetic materials. The secondary crushing section 22 includes a stirring rod 221 and crushing blades 222. The stirring rod 221 is a circular rod and is arranged horizontally. The stirring rod 221 is fixedly connected to the rotating shaft 211, and multiple stirring rods 221 are arranged circumferentially along the axis of the rotating shaft 211.

Each crushing blade 222 corresponds to one stirring rod 221.

[0034] The filter assembly 3 includes a filter plate 31 and a filter barrel 32. The filter plate 31 is circular and horizontally arranged. The filter plate 31 is fixedly connected to the crushing barrel 1 and rotatably connected to the rotating shaft 211.

Both the top and bottom of the filter barrel 32 are open, and the top end is fixedly connected to the bottom end of the filter plate 31.

[0035] When crushing magnetic materials, the operator pours the magnetic materials into the crushing barrel 1 through the feed pipe 11. The motor 6 drives the first gear 215 and the second gear 216 to rotate, causing the first crushing roller 212 and the second crushing roller 213 to rotate synchronously. The first crushing roller 212 and the second crushing roller 213 shear and crush the magnetic materials, resulting in initial crushing of the magnetic materials in the crushing barrel 1. After initial crushing, smaller magnetic materials pass through the filter plate 31 and enter the filter barrel 32, while larger magnetic materials pass through the primary crushing section 21 for further crushing. After the smaller magnetic materials enter the filter barrel 32, the secondary crushing section 22 crushes the magnetic materials again. When the crushing blades 222 crush the magnetic materials, the magnetic materials generate centrifugal force under the action of the crushing blades 222, causing the crushed magnetic materials that meet the usage requirements to be thrown out of the filter barrel 32. The magnetic materials that meet the usage requirements slide down the discharge plate 121 through the discharge port 12 into the discharge box 122, thus completing the crushing of the magnetic materials.

[0036] Reference Figure 3 Multiple sets of pushing components 4 are provided, and multiple sets are arranged circumferentially along the axis of the crushing barrel 1. The pushing component 4 includes a pushing plate 41, a connecting plate 42, and a drive rod 43. The pushing plate 41 is rectangular and vertically arranged. The pushing plate 41 is located inside the filter barrel 32 and is hinged to the filter barrel 32. Multiple pushing plates 41 are arranged vertically and are spaced apart from the secondary crushing section 22. A spring 411 is horizontally arranged on the side of the pushing plate 41 near the filter barrel 32. The two ends of the spring 411 are fixedly connected to the filter barrel 32 and the pushing plate 41, respectively. Multiple springs 411 are arranged vertically and correspond one-to-one with the pushing plate 41. The connecting plate 42 is rectangular and vertically arranged. The connecting plate 42 is located on the side of the filter barrel 32 away from the pushing plate 41. The drive rod 43 is rectangular and horizontally arranged. One end of the drive rod 43 is fixedly connected to the connecting plate 42, and the other end abuts against the pusher plate 41. The drive rod 43 is slidably connected to the filter box along its own length. Multiple drive rods 43 are arranged vertically and correspond one-to-one with the pusher plate 41.

[0037] Reference Figure 1 and Figure 2 Multiple sets of transmission components 5 are provided, and multiple sets are arranged circumferentially along the axis of the filter barrel 32. The transmission component 5 includes a first telescopic rod 51, a second telescopic rod 52, and a connecting pipe 53. The first telescopic rod 51 is horizontally arranged on the side of the crushing barrel 1 near the pusher plate 41 and is fixedly connected to the crushing barrel 1. The movable end of the first telescopic rod 51 is fixedly connected to the connecting plate 42. The movable end of the first telescopic rod 51 divides the fixed end of the first telescopic rod 51 into a first rod-containing cavity 511 and a first rodless cavity 512. The first rodless cavity 512 is filled with liquid.

[0038] The second telescopic rod 52 is horizontally positioned at the bottom of the crushing barrel 1 and is fixedly connected to it. The movable end of the second telescopic rod 52 divides the fixed end of the second telescopic rod 52 into a second rod-containing chamber 521 and a second rodless chamber 522, the second rodless chamber 522 being filled with liquid. The connecting pipe 53 is circular, with one end connected to the first rodless chamber 512 and the other end connected to the second rodless chamber 522. A cam 61 is provided at the bottom of the crushing barrel 1, horizontally positioned and fixedly connected to the output shaft of the motor 6, the cam 61 abutting against the movable end of the second telescopic rod 52.

[0039] When cam 61 rotates, it presses the movable end of the second telescopic rod 52, causing the movable end of the second telescopic rod 52 to contract. When the movable end of the second telescopic rod 52 contracts, the volume of the second rodless cavity 522 decreases, and the liquid in the second rodless cavity 522 flows through the connecting pipe 53 into the first rodless cavity 512. The volume of the first rodless cavity 512 increases, causing the movable end of the first telescopic rod 51 to extend. The movable end of the first telescopic rod 51 pushes the connecting plate 42 to move, and the connecting plate 42 drives the drive rod 43 to move. The drive rod 43 pushes the pusher plate 41 to rotate inside the filter barrel 32, causing the spring 411 to be in a stretched state. The pusher plate 41 pushes the magnetic material inside the filter barrel 32. When the tip of cam 61 rotates away from the movable end of the first telescopic rod 51, the spring 411 returns to its original position, and the pusher plate 41 drives the movable end of the first telescopic rod 51 to contract. The volume of the rodless cavity of the first telescopic rod 51 decreases, and the liquid in the first rodless cavity 512 flows through the connecting pipe 53 into the second rodless cavity 522, causing the movable end of the second telescopic rod 52 to return to its original position.

[0040] The implementation principle of the magnetic material crushing device in this application embodiment is as follows: When crushing magnetic materials, the operator pours the magnetic materials into the crushing barrel 1 through the feed pipe 11. The motor 6 drives the first crushing roller 212 and the second crushing roller 213 to rotate synchronously through gear transmission. The first crushing roller 212 and the second crushing roller 213 perform preliminary crushing of the magnetic materials. After preliminary crushing, the larger magnetic materials are crushed again through the primary crushing section 21, while the smaller magnetic materials enter the filter barrel 32 through the filter plate 31. After the smaller magnetic materials enter the filter barrel 32, the secondary crushing section 22 crushes the magnetic materials again. When the crushing blades 222 crush the magnetic materials, the magnetic materials generate centrifugal force under the action of the crushing blades 222. After crushing, the magnetic materials that meet the usage requirements are thrown out of the filter barrel 32. The magnetic materials that meet the usage requirements slide down the discharge plate 121 through the discharge port 12 into the discharge box 122.

[0041] When motor 6 rotates, the output shaft of motor 6 synchronously drives cam 61 to rotate. Cam 61 presses the movable end of the second telescopic rod 52, causing the movable end of the second telescopic rod 52 to contract. When the movable end of the second telescopic rod 52 contracts, the volume of the second rodless cavity 522 decreases. The liquid in the second rodless cavity 522 flows to the first rodless cavity 512 through the connecting pipe 53. The volume of the first rodless cavity 512 increases, causing the movable end of the first telescopic rod 51 to extend. The movable end of the first telescopic rod 51 pushes the connecting plate 42 to move. The connecting plate 42 drives the drive rod 43 to move. The drive rod 43 pushes the pusher plate 41 to rotate inside the filter barrel 32, causing the spring 411 to be in a stretched state. The pusher plate 41 pushes the magnetic material inside the filter barrel 32. When the tip of cam 61 rotates away from the movable end of the first telescopic rod 51, spring 411 returns to its original position, and pusher plate 41 drives the movable end of the first telescopic rod 51 to retract. The volume of the rodless cavity of the first telescopic rod 51 decreases, and the liquid in the first rodless cavity 512 flows through connecting pipe 53 into the second rodless cavity 522, causing the movable end of the second telescopic rod 52 to return to its original position. By pushing the magnetic material in the filter barrel 32 through pusher plate 41, the magnetic material in the filter barrel 32 is less likely to form a fixed movement trajectory, thereby improving the crushing efficiency of the magnetic material crushing device.

[0042] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
