Description

Technical Field

[0001] This utility model relates to a magnetic crushing device, and more particularly to a bidirectional magnetic crushing device for ferrite magnetic sheet material. Background Technology

[0002] Ferrite materials are magnetic sheet materials with specific shapes and specifications formed by high-temperature sintering of magnetic iron oxide powder, generally ranging in size from 180×180mm to 40×40mm. For end-use applications, the magnetic sheets need to be edged with double-sided or single-sided adhesive, crushed, and further sliced ​​or die-cut. In the magnetic sheet production process, the ferrite material is often first coated on a coating machine, and then the coated sheet is transferred to a crushing mechanism for crushing. Its main characteristics are: thin sheet form, relatively heavy weight, low strength, high brittleness, and easy breakage. Existing crushing equipment is not ideal, often resulting in uneven crushing and poor appearance of the coated magnetic sheets, leading to a low product yield.

[0003] To address the aforementioned problems, those skilled in the art are also researching improvements. For example, CN201820945535.X discloses a magnetic crushing device for electromagnetic shielding materials, including a crushing chamber and a coating mechanism. The crushing chamber is equipped with a spraying mechanism and two rollers, which are arranged in parallel and spaced apart. The spraying mechanism includes an air inlet and a feed inlet at the top of a collection chamber. The air inlet is connected to a high-pressure air pipe, and the feed inlet is connected to a SiC abrasive box via a pipe. The coating mechanism is located outside the crushing chamber. The coating film and magnetic material are transferred to the coated magnetic material via a transmission roller, which protects the film. This magnetic crushing device can crush the coated magnetic material longitudinally but cannot crush it laterally. For example, CN201810756266.7 discloses an electromagnetic sheet processing equipment. Although its magnetic crushing device is equipped with a transverse magnetic crushing mechanism and a longitudinal magnetic crushing mechanism, the transverse magnetic crushing mechanism cannot reciprocate to fully crush the magnetic material sheet. The electromagnetic sheet still needs to be manually transported to the coating device for coating. Further crushing, cutting, and testing all need to be done manually, which can easily lead to uneven particle size of the crushed magnetic material sheet and low crushing efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned defects of the prior art and provide a bidirectional ferrite magnetic material sheet crushing device that can make the magnetic material sheet particles after crushing uniform in shape, with uniform and rounded edge cracks, high product qualification rate, and high degree of automation.

[0005] The technical solution adopted by this utility model to solve its technical problem is a bidirectional magnetic crushing device for ferrite magnetic sheets, including a frame, the frame having a magnetic sheet transport function, and a longitudinal crushing mechanism and a transverse crushing mechanism arranged sequentially on the frame along the moving direction of the magnetic sheet; the longitudinal crushing mechanism and the transverse crushing mechanism are perpendicular to each other, and the transverse crushing mechanism is equipped with a sensor, which can identify the magnetic sheet entering the transverse crushing mechanism.

[0006] Furthermore, the transverse magnetic crushing mechanism includes a transverse crushing roller, a transverse position adjustment component, a height adjustment component, and a pad. The transverse crushing roller is mounted on the transverse position adjustment component, which is equipped with a height adjustment component for adjusting the height of the transverse crushing roller. The pad is located at the bottom of the transverse position adjustment component, and the magnetic material sheet can be transported onto the pad. The transverse position adjustment component can drive the transverse crushing roller to reciprocate on the pad. The sensor is mounted on the transverse position adjustment component and is electrically connected to the frame.

[0007] Furthermore, the lateral position adjustment assembly includes a pair of motor sliders, a pair of module tilting platforms, a pair of lead screws, and a pair of motors; the lateral rolling roller is disposed between the pair of motor sliders, the pair of motor sliders is connected to the pair of lead screws in a one-to-one correspondence, the pair of lead screws is disposed in the pair of module tilting platforms in a one-to-one correspondence, and a motor is fixedly disposed at one end of each module tilting platform, the output shaft of the motor is connected to the lead screw to drive the lead screw to rotate.

[0008] Furthermore, the height adjustment component includes a pair of cylinders, and a mounting frame is provided on the pair of module tilting platforms. The pair of cylinders are evenly and symmetrically arranged on the mounting frame. The output end of the cylinder can abut against the frame to drive the module tilting platform to drive the transverse rolling roller to reciprocate linearly in the vertical direction.

[0009] Furthermore, the pad includes a metal pad and a rubber pad, the rubber pad is disposed on the metal pad, and the metal pad is fixedly connected to the bottom of the module tilting platform.

[0010] Furthermore, the sensor includes a proximity switch disposed on the lateral position adjustment assembly.

[0011] Furthermore, the frame includes a conveyor belt and a skeleton, the conveyor belt is disposed between pairs of skeletons, and the longitudinal magnetic crushing mechanism and the transverse magnetic crushing mechanism are sequentially disposed on the conveyor belt.

[0012] Furthermore, the longitudinal crushing mechanism includes a feeding shaft, a cleaning roller, and a longitudinal crushing roller. The feeding shaft, the longitudinal crushing roller, and the cleaning roller are sequentially arranged on the conveyor belt, and the magnetic material sheet is guided by the feeding shaft to be fed onto the conveyor belt.

[0013] This utility model relates to a bidirectional ferrite magnetic material sheet crushing device. Through a longitudinal crushing mechanism and a transverse crushing mechanism sequentially arranged on a frame, the magnetic material sheets entering the device are first longitudinally crushed by the longitudinal crushing mechanism. Then, after the transverse crushing mechanism's sensor detects the magnetic material sheet, the frame stops transporting the sheet. The transverse crushing mechanism then further crushes the sheet by rolling it laterally. This ensures that the magnetic material sheets on the frame undergo two crushing processes—longitudinal and transverse—resulting in uniformly shaped magnetic material sheets with smooth, even edge cracks and a high product qualification rate. Furthermore, the transverse and longitudinal crushing mechanisms are independently configured, facilitating installation, maintenance, and replacement during use. The sensor setup further enhances the automation of the device: it enables the magnetic material sheet to be quickly identified by the sensor when it passes through the transverse crushing mechanism. When the sensor detects that a magnetic material sheet has entered the transverse crushing mechanism, the frame will automatically stop conveying the magnetic material sheet. After the transverse crushing mechanism completes one crushing of the magnetic material sheet, the frame will automatically resume conveying the magnetic material sheet without manual operation.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0019] like Figure 1As shown, an embodiment of the bidirectional magnetic breaking device for ferrite magnetic sheets includes a frame 3 with the function of transporting magnetic sheets. A longitudinal magnetic breaking mechanism 1 and a transverse magnetic breaking mechanism 2 are sequentially arranged on the frame 3 along the moving direction of the magnetic sheets. The longitudinal magnetic breaking mechanism 1 and the transverse magnetic breaking mechanism 2 are perpendicular to each other. The transverse magnetic breaking mechanism 2 is equipped with a sensor 4, which is electrically connected to the frame 3. The longitudinal magnetic breaking mechanism 1 and the transverse magnetic breaking mechanism 2 are perpendicular to each other, and the sensor 4 can automatically identify the magnetic sheets entering the transverse magnetic breaking mechanism 2.

[0020] Ferrite magnetic sheets are conveyed from frame 3 to the longitudinal crushing mechanism 1, where they undergo longitudinal crushing. After longitudinal crushing, the sheets enter the transverse crushing mechanism 2. Upon detection of the sheets by sensors in the transverse crushing mechanism 2, frame 3 automatically stops transporting the sheets. The transverse crushing mechanism 2 then crushes the sheets transversely, ensuring the sheets undergo both longitudinal and transverse crushing processes. This results in uniformly shaped magnetic particles with smooth, rounded edges, leading to a high product yield. Furthermore, the transverse and longitudinal crushing mechanisms 2 are independently configured, facilitating installation, maintenance, and replacement during use. The sensor 4 further enhances the automation of the device: when the magnetic material sheet crushed by the longitudinal crushing mechanism 1 enters the transverse crushing mechanism 2, the sensor 4 can quickly identify the magnetic material sheet and cause the frame 3 to automatically stop transporting the magnetic material sheet; after the transverse crushing mechanism completes one crushing of the magnetic material sheet, the frame 3 will automatically resume the magnetic material sheet transporting work and start the next round of magnetic material sheet transporting, crushing and crushing work; this cycle repeats without manual operation.

[0021] In another preferred embodiment, the bidirectional magnetic breaking device for ferrite magnetic materials is further equipped with a PLC controller. The PLC controller is electrically connected to the longitudinal magnetic breaking mechanism 1, the transverse magnetic breaking mechanism 2, the sensor, and the frame 3 to realize the automated transfer of longitudinal magnetic breaking, transverse magnetic breaking, and magnetic materials.

[0022] Reference Figure 2The transverse crushing mechanism 2 is also equipped with a transverse crushing roller 26, a transverse position adjustment component, a height adjustment component, and a pad. The transverse crushing roller 26 is mounted on the transverse position adjustment component, which is equipped with a height adjustment component for adjusting the height of the transverse crushing roller 26. The pad is mounted at the bottom of the transverse position adjustment component, and the magnetic material sheet can be conveyed onto the pad. The transverse position adjustment component can drive the transverse crushing roller 26 to reciprocate on the pad. The sensor is mounted on the transverse position adjustment component and is electrically connected to the frame 3. The lateral position adjustment assembly includes a pair of motor sliders 25, a pair of module tilting platforms 23, a pair of lead screws 24, and a pair of motors 21. The lateral rolling rollers 26 are arranged between the pairs of motor sliders 25. The pairs of motor sliders 25 are connected to the pairs of lead screws 24 in a one-to-one correspondence. The pairs of lead screws 24 are arranged in the pairs of module tilting platforms 23 in a one-to-one correspondence. A motor 21 is fixedly arranged at one end of each module tilting platform 23. The output end of each motor 21 is connected to the lead screw 24 to drive the lead screw 24 to rotate.

[0023] The height adjustment assembly includes a pair of cylinders 29. A mounting frame is provided on the pair of module tilting platforms 23. The pair of cylinders 29 are evenly and symmetrically arranged on the mounting frame. The output end of the cylinder 29 can abut against the frame 3 to drive the module tilting platform 23 to drive the transverse rolling roller 26 in a linear reciprocating motion in the vertical direction. The pad includes a metal pad 27 and a rubber pad 28. The rubber pad 28 is disposed on the metal pad 27, and the metal pad 27 is fixedly connected to the bottom of the module tilting platform 23.

[0024] In this embodiment, when the sensor detects the magnetic material sheet, the frame 3 that conveys the magnetic material sheet forward stops conveying it. The height adjustment component starts working, and the cylinder 29 moves downward to a designated position so that the transverse crushing roller 26 can contact the magnetic material sheet. After the transverse crushing roller 26 contacts the magnetic material sheet, the transverse position adjustment component starts working, and the paired motors 21 operate synchronously, causing the lead screw 24 to rotate. This drives the motor slider 25 to move linearly back and forth in the horizontal direction. The motor slider 25 then drives the transverse crushing roller 26 to uniformly and quickly crush the magnetic material sheet on the rubber pad 28. Under the pressure of the standard cylinder 29 and the crushing of the transverse crushing roller 26, the ferrite magnetic material sheet deforms on the rubber pad 28, completing the transverse crushing effect. The rubber pad 28 is designed to avoid uneven crushing caused by rigid contact between the magnetic material sheet and the pad during the transverse crushing process. The output shafts of the paired motors 21 are connected to the lead screw 24 via couplings 22.

[0025] In another preferred embodiment, sensor 4 is a proximity switch, which is mounted on the lateral position adjustment assembly. A proximity switch is a position switch that can be operated without direct mechanical contact with moving parts. When an object approaches the sensing surface of the switch to the operating distance, the switch can be activated without mechanical contact or pressure, thereby driving DC electrical appliances or providing control commands to a PLC control device. A proximity switch is a type of switch sensor (i.e., a contactless switch). It possesses the characteristics of limit switches and microswitches, while also having sensing capabilities. It is reliable, stable, has a fast frequency response, long service life, strong anti-interference ability, and is waterproof, shockproof, and corrosion-resistant. Products are available in inductive, capacitive, Hall effect, AC, and DC types.

[0026] Furthermore, the frame 3 includes a conveyor belt and a skeleton, with the conveyor belt positioned between pairs of skeletons. A longitudinal magnetic crushing mechanism 1 and a transverse magnetic crushing mechanism 2 are sequentially arranged on the conveyor belt. The longitudinal magnetic crushing mechanism 1 includes a feeding shaft, a longitudinal pressing roller, and a cleaning roller, all sequentially arranged on the conveyor belt. Magnetic sheets are guided onto the conveyor belt by the feeding shaft. The surfaces of the pressing roller and the cleaning roller are made of hard plastic, ensuring uniform force distribution across the entire plane and preventing breakage of the magnetic sheets due to excessive force at a single point. In a preferred embodiment, three pressing rollers and one cleaning roller are used to perform uniform and rapid magnetic crushing of the magnetic sheets.

[0027] This utility model also provides a method of using the above-mentioned bidirectional magnetic crushing device for ferrite magnetic sheets: After the magnetic sheet enters the equipment through the feeding shaft, it is driven by the conveyor belt on the frame 3 to complete the longitudinal crushing through the longitudinal crushing roller and the cleaning roller. After passing through the cleaning roller, it enters the transverse crushing mechanism 2. When the proximity switch of the sensor 4 detects the entry of the magnetic sheet, it stops the servo motor and controls the conveyor belt to stop its conveying motion. The standard SE cylinder 29 drives the module tilting platform 23 of the transverse crushing mechanism 2 to move downward to a specified distance so that the transverse crushing roller 26 contacts the magnetic sheet. When the transverse crushing roller 26 contacts the magnetic sheet, the motor 21 drives the transverse crushing roller 26 to move repeatedly to complete the transverse crushing. After the transverse crushing roller 26 of the transverse crushing mechanism 2 completes one crushing, the standard SE cylinder 29 lifts up, and the servo motor on the frame 3 continues to drive the conveyor belt to move forward and convey the magnetic sheet.

[0028] 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.

[0029] The above descriptions only illustrate several embodiments of this utility model, and are quite specific and detailed. These embodiments should not be construed as limiting the scope of protection of the utility model patent application. For those skilled in the art, various modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the scope of protection of this utility model. Therefore, the scope of protection of this utility model patent should be determined by the claims as stated in the claims statement.
