Description

Technical Field

[0001] The invention belongs to the technical field of permanent magnet rollers, and in particular relates to a permanent magnet roller with strong driving force. Background Art

[0002] Against the backdrop of accelerating global industrialization, the amount of solid waste generated has increased dramatically. Many heat and power cogeneration and centralized heating and gas supply enterprises use coal-fired coupling to treat general solid waste (industrial combustible waste, municipal sludge, industrial sludge, decoration waste, agricultural and forestry waste, etc.) for harmless resource incineration. At present, most of the disposal projects of general industrial solid waste use belt conveyors to complete the entire process of loading, crushing, sorting, magnetic separation, and material equalization transportation to incineration. Since the solid waste is mainly waste scraps from manufacturing enterprises such as clothing, bags, shoes, and leather, which are mixed with a small amount of hard debris such as metal, the metal has great damage to crushing and boilers, so the magnetic separation link is crucial. Detection, sorting, separation, equalization, and transportation of metals can realize the sorting of metals in different volumes on demand, prevent fatal metals from damaging the subsequent process equipment, and extend the service life of the equipment and the stability and reliability of the equipment operation. Iron removal equipment is an important line of defense. Permanent magnetic rollers play a pivotal role in iron removal equipment.

[0003] However, the end covers at both ends of the existing permanent magnet roller are an integrated welded structure, or are connected by bolts, which makes it inconvenient to repair the permanent magnet roller when the magnets in the permanent magnet roller become loose or fail.

[0004] In summary, there is a need for a cylinder that can be assembled and disassembled to facilitate maintenance of the interior of the permanent magnet roller when a fault occurs. Summary of the invention

[0005] The purpose of the present invention is to provide a permanent magnetic roller with strong driving force. The roller can connect and fix the permanent magnetic roller body by pushing the clamping block into the clamping slot, and vice versa, it can be disassembled to achieve the technical effect of convenient assembly and disassembly.

[0006] The technical solution adopted by the present invention to solve the above problems is: a strong driving force permanent magnetic roller, comprising: Permanent magnetic roller body; A quick connection assembly, the quick connection assembly includes two groups of connection seats respectively arranged on both sides of the permanent magnetic roller body, a sleeve is rotatably connected to the connection seat and the sleeve is sleeved on the outside of the end of the permanent magnetic roller body, a screw is rotatably connected to the sleeve, the external thread of the screw is connected to a moving ring, a plurality of connection frames are fixedly connected circumferentially on the moving ring, a plurality of through grooves are opened circumferentially on the sleeve, a clamping block is slidably connected inside the through groove, a connecting rod is symmetrically hinged between the clamping block and the connection frame through a hinge, and a plurality of clamping grooves are opened circumferentially on the outside of the end of the permanent magnetic roller body.

[0007] Among them, the permanent magnetic roller body is the core component of the entire device, which contains permanent magnets set inside or outside, and is designed to provide driving force and magnetic force for processing magnetic materials or generating magnetic fields.

[0008] The quick-connect assembly is used to quickly and easily install and remove the permanent magnet roller body, including the following specific sub-assemblies: The connecting seat is a fixed component arranged on both sides of the permanent magnetic roller body, serving as the basis for the connection and support device; The sleeve is sleeved on the outside of the end of the permanent magnetic roller body and is rotatably connected to the connecting seat, providing a rotating connection point so that the roller body can rotate freely on the connecting seat.

[0009] The lead screw is rotatably connected to the sleeve and is threadedly connected to a moving ring. The axial movement of the moving ring is achieved through rotational motion, thereby driving the relative movement of other components.

[0010] The moving ring is threadedly connected to the outside of the screw rod and is circumferentially fixedly connected to a number of connecting frames. It realizes its own axial movement through the rotational movement of the screw rod, driving the movement of the connecting frames and the clamping blocks.

[0011] The connecting frame is fixedly connected to the moving ring, and connects and transmits the movement of the moving ring to the clamping block.

[0012] The through groove is opened circumferentially on the sleeve and is used to accommodate the card block, allowing the card block to slide in the through groove to achieve locking and releasing functions.

[0013] The clamping block is slidably connected in the through slot of the sleeve, is hinged with the connecting frame through a connecting rod, and slides in the through slot to clamp in or out of the clamping slot at the end of the permanent magnetic roller body to achieve locking or release.

[0014] The connecting rod is symmetrically hinged between the clamping block and the connecting frame through hinges, and transmits the axial movement of the moving ring to make the clamping block slide in the through groove.

[0015] The clamping groove is opened on the outer circumference of the end of the permanent magnetic roller body and cooperates with the clamping block to lock or fix the permanent magnetic roller body.

[0016] When the permanent magnetic roller body needs to be installed or removed, the screw is rotated to make the moving ring move along the axial direction of the screw, and the moving ring moves with the connecting frame and the connecting rod, thereby driving the card block to slide in the through groove. When the card block slides to the appropriate position, it can be aligned with the card slot of the permanent magnetic roller body and snapped in, thereby locking the permanent magnetic roller body. Conversely, when disassembly is required, the screw is rotated in the opposite direction to make the card block withdraw from the card slot, thereby releasing the permanent magnetic roller body.

[0017] A further preferred technical solution is that the permanent magnetic roller body comprises a keel bracket, a cylinder is welded to the outside of the keel bracket, a plurality of magnets are stacked between the keel bracket and the inner wall of the cylinder, and the surface of the cylinder is embossed.

[0018] Among them, the keel bracket is the internal support frame, which usually has a solid structure to provide stability and support, providing structural support for the entire roller to ensure that the roller maintains its shape and strength during use.

[0019] The cylinder is a cylindrical shell covering the outside of the keel bracket, protecting the internal components (such as magnets) and providing a contact surface with the external environment. Its surface is embossed to increase the friction and wear resistance of the surface, making it more suitable for use in various operating conditions.

[0020] Several magnets are stacked between the keel bracket and the inner wall of the cylinder to provide a magnetic field for adsorbing and processing magnetic materials. The arrangement and number of the magnets affect the strength and distribution of the magnetic field, making it suitable for specific industrial applications.

[0021] The keel bracket provides the necessary structural support for the entire permanent magnetic roller, ensuring that it remains stable and reliable during operation. The superimposed magnets provide a strong magnetic field between the cylinder and the keel bracket to attract and hold the magnetic material on the roller surface to achieve material processing and sorting. The cylinder not only protects the internal magnets and keel bracket, but also provides a wear-resistant and frictional outer surface, especially after embossing, it is more adaptable to high friction and high contact strength application scenarios. This design of permanent magnetic roller body is widely used in multiple industrial fields, especially in operations that require processing or sorting of magnetic materials, because it combines strong magnetic force with solid structural support.

[0022] A further preferred technical solution is that the keel bracket includes an axis, polygonal plates are fixedly welded to the outside of both sides of the axis, support plates are circumferentially welded to the outside of the axis, and sealing plates are also welded to the outside of both sides of the axis.

[0023] Among them, the axis, as the core part of the keel bracket, runs through the central axis of the entire roller, provides the main support and bearing functions, and is the connection and fixing basis for other structural components.

[0024] The polygonal plate is a polygonal plate fixedly welded to the outside of both sides of the axis to provide additional structural support and stability, and the side-shaped design may help to disperse stress and provide more fixing points to ensure the overall rigidity and strength of the bracket.

[0025] The support plate is a plate-like structure welded circumferentially to the outside of the shaft to enhance the structural strength and stability of the shaft and provide additional connection points and support surfaces to fix other components such as magnets and cylinders. The circumferential arrangement of the support plate helps to evenly distribute the load and prevent local stress concentration.

[0026] The sealing plate is a plate-like structure welded to the outside of both sides of the shaft. It is usually circular or other shapes suitable for closed ends. It closes both ends of the shaft, protects the internal structural components, prevents foreign objects from entering, provides structural integrity of the ends for the entire keel bracket, and ensures its stability during operation.

[0027] A further preferred technical solution is that: a welding opening and a mounting hole are provided on the support plate.

[0028] A further preferred technical solution is that guide rods are symmetrically fixedly connected to the sleeve and the guide rods are slidably connected to the movable ring.

[0029] A further preferred technical solution is that the end of the guide rod is fixedly connected to a limiting plate.

[0030] A further preferred technical solution is that: an anti-slip knob is fixedly connected to the end of the screw rod.

[0031] A further preferred technical solution is that a cylinder is fixedly connected to the connecting seat on one side.

[0032] A further preferred technical solution is that both ends of the permanent magnetic roller body are fixedly connected with positioning bars, the inner wall of the sleeve is provided with a positioning groove, and the positioning groove is slidably connected to the positioning bar.

[0033] A further preferred technical solution is that: a plurality of guide brackets are fixedly connected to the outer circumference of the sleeve, and the guide brackets are slidably connected to the clamping block.

[0034] In summary, the present invention has the following benefits: 1. The roller of the present invention completes the connection and fixation of the permanent magnetic roller body by pushing the clamping block into the clamping slot, and vice versa, it can be disassembled to achieve the technical effect of convenient assembly and disassembly.

[0035] 2. The polygonal keel bracket adopted in the present invention has a mounting bracket size that just matches the size of the magnet, and the sharp corners of the magnet are neatly connected. After the magnet is assembled, it is placed in the cylinder. The gap between the cylinder wall and the magnet is basically 1mm, which maximizes the magnetic field strength on the surface of the magnet to be perfectly reflected on the surface of the permanent magnet roller. Even when the material layer is relatively thick, it can still absorb metal at a distance. Reduce the number of fish that slip through the net. More damage to the subsequent process equipment is avoided to ensure the smooth operation of the blending.

[0036] 3. The present invention adopts the arrangement of N and S in a cross combination. Since the magnetic induction lines form a closed line between each row and each column, the density of the magnetic induction lines is greatly increased, thereby significantly increasing the magnetic force on the surface of the permanent magnet roller and forming a complete magnetic field induction loop, which is more conducive to the adsorption of metal.

[0037] 4. The present invention adopts a method of superimposing a layer of strong magnet on a layer of general magnet. The superimposed layer of general magnet increases the surface magnetic field of the strong magnet by about 200 gauss, and avoids the loss of the magnetic field of the bottom layer of the strong magnet. It can also make the inner circle of the keel as large as possible, making the gap between each column of magnets smaller, thereby forming a complete closed magnetic field.

[0038] 5. The present invention calculates the diameter of the inner circle by the thickness of a single magnet and the number of superpositions in a circular arrangement, and then arranges a polygon with the inner circle diameter as the vertex according to the volume of the magnet. The polygon is used as a keel support to form a neat array of N rows and N columns. Compared with the traditional method, the gap between the magnets is minimized to the maximum extent, so that the magnets are as close to the outer circle of the cylinder as possible, greatly increasing the magnetic force on the surface of the permanent magnet roller.

Two groups of guide rods 2 are fixedly connected and the guide rods 2 are slidably connected to the moving ring 14, which can play a certain guiding role in the vertical movement of the moving ring 14. The end of the guide rod 2 is fixedly connected to a limit plate to prevent the moving ring 14 from separating from the guide rod 2. Both ends of the permanent magnetic roller body 1 are symmetrically fixedly connected with positioning strips 4. The inner wall of the sleeve 12 is symmetrically provided with positioning grooves and the positioning grooves and the positioning strips 4 are slidably connected to ensure that the slot 18 can be aligned with the block 16. The outside of the sleeve 12 is equidistantly circumferentially fixedly connected with a guide bracket 5 and the guide bracket 5 is slidably connected to the block 16 on the same side, which can play a certain guiding role in the horizontal movement of the block 16. A cylinder 6 is fixedly connected to a connecting seat 11 on one side to facilitate the installation of the permanent magnetic roller body 1.

[0044] The implementation principle of a strong driving force permanent magnetic roller in the embodiment of the present application is as follows: during assembly, first select a relatively tough and wear-resistant round steel as the axis 1011, the overall surface of the axis 1011 is rough-turned, and a fine turning margin is reserved to ensure its own radial runout, and the welding position and installation hole of the polygonal plate 1012 are laser-cut, and 5 discs matching the polygonal plate 1012 and the axis 1011 are accurately cut as the support plate 1013 of the keel, and a welding port is reserved, and the axis 1011 and the disc are used as the reference, and each is welded and polished to avoid the neat assembly of the magnets affected by the welding points, so as to prepare for the seamless fit of the magnets and the cylinder 102, and then the required magnets are calculated according to the drawings, with half the number of N poles and half the number of S poles. The circumferential direction is defined as a row, and the length direction is defined as a column. The magnets are arranged in two different directions, N and S, respectively, forming a staggered arrangement of N and S in any direction. The gap between the magnets is small, and a high-density closed-loop magnetic field line has been formed around the magnets, thereby greatly increasing the magnetic field strength. At this time, if measured with a meter, it is much higher than the magnetic field on the surface of the magnet alone. After all the magnets are assembled, prepare to weld the sealing plates 1014 at both ends of the cylinder 102. The sealing plates 1014 originally fit the size of the axis 1011. After welding, use a level ruler to compare the outer diameters of the magnet and the sealing plate 1014. The sealing plate 1014 is adjusted according to the outer diameter of the magnet in the entire circumferential direction. When rotated to any point, the sealing plate 1014 is only about 1mm larger than the outer diameter of the magnet. Then the sealing plate 1014 is welded firmly to the shaft 1011, and then the size of the 304 stainless steel plate is calculated based on the outer diameter of the cylinder 102. The plate is first embossed to increase the friction on the surface of the cylinder 102, and then rolled by a winch. After multiple repairs, the cylinder 102 is as round as possible. The inner diameter of the cylinder 102 after rolling is measured and compared with the outer diameter of the sealing plate 1014 that has been fine-turned above. The excess is cut off and spot welded section by section, and then fully welded to ensure that the inner diameter of the rolled cylinder 102 is consistent with the outer diameter of the sealing plate 1014. To prepare for the final molding of the permanent magnetic roller body 1, the keel bracket 101 with assembled magnets is slowly placed into the stainless steel cylinder 102, and the size is placed as required by the drawing, and then the outer circle of the sealing plate 1014 and the 304 stainless steel cylinder 102 are welded firmly.

[0045] During installation, first insert one end of the permanent magnetic roller body 1 into the sleeve 12, then start the cylinder 6 to push the other side sleeve 12 to be sleeved on the other end of the permanent magnetic roller body 1, and use the sliding cooperation between the positioning strip 4 and the positioning groove to ensure that the slot 18 is aligned with the block 16. Finally, turn the anti-slip knob 3 to drive the screw rod 13 to rotate. The rotation of the screw rod 13 will drive the moving ring 14 to move vertically downward. The downward movement of the moving ring 14 drives the connecting frame 15 to move downward. Use the hinged effect between the connecting frame 15 and the block 16 and the connecting rod 17 to push the block 16 into the slot 18 to complete the connection and fixation of the permanent magnetic roller body 1. Otherwise, it can be disassembled.

[0046] In addition, a further improvement is that a welding opening and a mounting hole are provided on the support plate 1013 to facilitate the installation of the magnet.
