Description

Technical Field

[0001] This invention belongs to the field of magnetic material processing technology, specifically relating to a magnetic material degumming and cleaning machine and cleaning method. Background Technology

[0002] In the production and processing of magnetic materials, adhesive is used to bond and fix the magnetic materials during the cutting process. After cutting, the adhesive is removed before proceeding to the next processing step. Incomplete removal of the adhesive will seriously affect the processing accuracy, performance indicators, and product quality of the subsequent magnetic materials. Currently, the industry mostly uses heated immersion cleaning for removing adhesive from magnetic materials. This process requires manual operation, which is not only labor-intensive and inefficient, but also suffers from incomplete cleaning and uneven cleanliness, making it difficult to meet the needs of large-scale, high-efficiency magnetic material production.

[0003] Meanwhile, most existing cleaning equipment lacks an integrated feeding, cleaning, and discharging structure. After cleaning, the magnetic materials need to be manually transferred to subsequent processing equipment, which not only increases labor costs but also easily causes damage to the magnetic materials or secondary pollution during the transfer process, making continuous production impossible.

[0004] Therefore, it is necessary to design a magnetic material degumming and cleaning equipment that can achieve automatic feeding, efficient degumming and cleaning, automatic discharge, and seamless integration with subsequent processing lines to solve the pain points in the existing technology. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a magnetic material degumming and cleaning machine and cleaning method to solve the technical problems of high labor intensity, low efficiency, incomplete cleaning, and inability to achieve automatic feeding, discharging and seamless connection with subsequent processing lines in the magnetic material degumming and cleaning process in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a magnetic material degumming and cleaning machine, including a frame, a water tank fixedly mounted on the frame, a roller rotatably mounted on the frame, the roller being arranged in a mesh pattern, the roller's axis being horizontal, the lower half of the roller extending into the water tank, the first end of the roller being closed, and the second end of the roller being open, a drive mechanism fixedly mounted on the frame and fixedly connected to the first end of the roller, a feed plate extending into the roller from the second end of the roller being fixedly mounted on the frame, a conveyor belt fixedly mounted below the roller, the conveyor belt extending out of the water tank away from the roller end, and a spiral blade coaxially mounted on the roller and fixedly mounted inside the roller near the second end of the roller, the roller rotating clockwise can bring magnetic materials into the roller through the spiral blade, and the roller rotating counterclockwise can bring magnetic materials out of the roller through the spiral blade.

[0007] Furthermore, a cylindrical collection box is fixedly installed on the frame. The collection box is coaxially disposed inside the drum and is rotatably connected to the drum. A strip-shaped notch extending along the axial direction of the collection box is provided at the top of the collection box. A scraper is fixedly installed inside the drum and is in contact with the outer wall of the collection box. The scraper is spirally arranged along the axial direction of the collection box, and the spiral direction of the scraper is the same as the spiral direction of the spiral blade.

[0008] Furthermore, a support ring is fixedly connected to the second end of the roller via a connecting rod, and the collection box is rotatably connected to the roller through the support ring. A horizontal baffle extending radially along the roller is fixedly connected to the collection box near the second end of the roller.

[0009] Furthermore, the scraper is a mesh structure that can restrict the passage of colloid, and an elastic brush strip is fixedly disposed on the scraper near the roller side. The elastic brush strip is spirally arranged along the scraper, and the gap between the elastic brush strip and the roller is less than the height of the magnetic material.

[0010] Furthermore, the water storage tank is fixedly connected to a plurality of air pipes arranged around the outer wall of the lower half of the roller, and the air pipes extend out of the water storage tank and are fixedly connected to an inflation mechanism.

[0011] Furthermore, a heater for heating the water in the water storage tank is fixedly installed on the side wall of the water storage tank.

[0012] A cleaning method for a magnetic material degumming and cleaning machine includes the following steps: S1: Start the heater through the control box to heat the cleaning water in the water storage tank to the preset temperature; S2: Pour the magnetic material to be cleaned into the drum through the feed plate. Control the drive mechanism through the control box to drive the drum to rotate in the forward direction so that the drum carries the magnetic material to be cleaned into the drum and continuously stirs it. The spiral blades inside the drum prevent the magnetic material from falling from the feed end of the drum. S3: After the preset cleaning time, the control box controls the drive mechanism to drive the drum to rotate in the opposite direction. The spiral blades follow the reverse rotation of drum 3 to push the magnetic material to the discharge end of the drum so that the magnetic material falls onto the conveyor belt. S4: The cleaned magnetic materials are transported to the subsequent processing equipment via a conveyor belt.

[0013] The beneficial effects of this invention are as follows: 1. High degree of automation: The automatic feeding and discharging of magnetic materials is achieved through the forward and reverse rotation of the rollers and the cooperation of the spiral blades. With the design of the conveyor belt and the discharge port, there is no need for manual transfer of magnetic materials, which greatly reduces labor intensity and improves production efficiency. 2. High degumming and cleaning efficiency: The heater heats the cleaning water, accelerating the degumming speed. At the same time, the drum drives the magnetic material to agitate, ensuring full contact between the magnetic material and the water, resulting in a more thorough and uniform cleaning. The air filling mechanism accelerates the turbulence of the water, further speeding up the degumming efficiency. The elastic brush strips can assist in scraping off the adhesive on the surface of the magnetic material, improving the degumming efficiency. 3. Strong compatibility: The discharge port can be directly connected to subsequent processing equipment such as ultrasonic cleaning lines and drying lines to realize continuous production line operation of magnetic materials processing and adapt to different production needs; 4. Easy to operate: The operating parameters of each component of the equipment are centrally controlled through the control box, and can be flexibly adjusted according to the specifications of the magnetic material and the type of adhesive. The operation is simple and easy to understand, reducing the technical threshold for operators. 5. Facilitates colloid collection: The scraper works in conjunction with the roller, allowing the roller to automatically collect the detached colloid during rotation.

[0014] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0016] The following components are marked in the attached diagram: frame 1, water tank 2, heater 201, roller 3, spiral blade 301, connecting rod 302, support ring 303, drive mechanism 4, feed plate 5, conveyor belt 6, control box 7, collection box 8, strip notch 801, scraper 802, horizontal baffle 803, elastic brush strip 804, air pipe 9. Detailed Implementation

[0017] like Figures 1-4As shown, the present invention provides a magnetic material degumming and cleaning machine, comprising: a frame 1, a water tank 2 fixedly mounted on the frame 1, a roller 3 rotatably mounted on the frame 1, the roller 3 being arranged in a mesh pattern, the axis of the roller 3 being horizontally oriented, the lower half of the roller 3 extending into the water tank 2, the first end of the roller 3 being closed, and the second end of the roller 3 being open, a drive mechanism 4 fixedly mounted on the frame 1 and fixedly connected to the first end of the roller 3, the drive mechanism 4 being used to output rotational power to drive the roller 3 to rotate, a feed plate 5 extending from the second end of the roller 3 into the roller 3 being fixedly mounted on the frame 1, an inclined conveyor belt 6 fixedly mounted below the roller 3, the conveyor belt 6 extending away from the end of the roller 3 from the water tank 2, and a spiral blade 301 fixedly mounted inside the roller 3, the roller 3 rotating clockwise being able to bring magnetic materials into the roller 3 through the spiral blade 301, and the roller 3 rotating counterclockwise being able to bring magnetic materials out of the roller 3 through the spiral blade 301.

[0018] In this design, the drum 3 uses a perforated screen structure to ensure that water from the water tank 2 can enter the drum 3 and fully contact the magnetic material, while also facilitating the discharge of impurities generated during the cleaning process. A spiral blade 301 is fixedly installed on the inner side of the drum 3 near its second end. The rotation direction of the spiral blade 301, in conjunction with the rotation direction of the drum 3, controls the feeding and discharging: when the drum 3 rotates forward, the spiral blade 301 blocks the magnetic material entering the drum 3, preventing it from falling from the front end and ensuring thorough agitation and cleaning within the drum; when the drum 3 rotates in reverse, the spiral blade 301 pushes the magnetic material towards the second end of the drum 3, achieving automatic discharge of the magnetic material; the feed plate 5 is equipped with... The feed plate 5, positioned above the front end of the drum 3, has its outlet aligned with the feed end of the drum 3. The magnetic material to be cleaned is poured in through the feed plate 5 and slides along the inclined inner wall of the feed plate 5 into the drum 3, achieving automatic feeding. The drive mechanism 4 is a power reduction motor, connected to the drum 3, providing power for its forward and reverse rotation. The motor speed can be adjusted via the control box 7 fixed on the frame 1, thereby controlling the agitation and discharge speed of the drum 3 to accommodate the cleaning needs of different specifications of magnetic materials. A water tank 2 is located below the drum 3, storing cleaning water. The lower half of the drum 3 is immersed in the water in the tank 2, ensuring the cleanliness of the magnetic material inside the drum 3. It can fully contact water; the side wall of the water storage tank 2 is equipped with an inlet and an outlet for easy periodic replacement of cleaning water; a heater 201 is installed on the side wall of the water storage tank 2, which is electrically connected to the control box 7 to heat the cleaning water in the water storage tank 2. By increasing the water temperature, the dissolution and detachment of the adhesive on the surface of the magnetic material is accelerated, improving the degumming and cleaning efficiency. At the same time, the heating temperature can be adjusted by the control box 7 according to the characteristics of the magnetic material and the type of adhesive to avoid the high temperature affecting the performance of the magnetic material; the conveyor belt 6 is set below the front end of the roller 3 and aligned with the discharge end of the roller 3. When the roller 3 reverses to discharge, the magnetic material falling from the roller 3 falls directly onto the conveyor belt 6, which is driven by a motor. The system operates by conveying the cleaned magnetic material towards the discharge port, which is located at the end of the conveyor belt 6. The height of the discharge port is adapted to the feed end of subsequent processing equipment (such as ultrasonic cleaning lines and drying lines). After being conveyed to the discharge port by the conveyor belt 6, the cleaned magnetic material can directly enter the subsequent processing equipment, achieving a seamless connection between cleaning and subsequent processing. The control box 7 is electrically connected to the power reduction motor, heater, and conveyor belt motor. The control box is equipped with operation buttons, a display screen, and parameter adjustment knobs, which can realize centralized control of the forward and reverse rotation of the drum, rotation speed, heater temperature, and conveyor belt speed. At the same time, a timer function can be set to automatically control the cleaning time and improve the automation level of the equipment.

[0019] In one embodiment of the present invention, a cylindrical collection box 8 is fixedly installed on the frame 1. The collection box 8 is coaxially disposed inside the roller 3 and is rotatably connected to the roller 3. A strip-shaped notch 801 extending along the axial direction of the collection box 8 is provided at the top of the collection box 8. A scraper 802 is fixedly installed inside the roller 3 and is in contact with the outer wall of the collection box 8. The scraper 802 is spirally arranged along the axial direction of the collection box 8, and the spiral direction of the scraper 802 is the same as the spiral direction of the spiral blade 301.

[0020] In this scheme, during the cleaning process, the colloid that falls off the magnetic material floats on the water surface due to buoyancy. The collection box 8 and the roller 3 are coaxially arranged, so that the lower half of the collection box 8 is submerged below the water surface. The detached colloid accumulates on the bottom wall of the collection box 8 due to buoyancy. When the roller 3 is driven to rotate by the drive mechanism 4, the scraper 802 is driven to rotate, thereby scraping the colloid on the bottom wall of the collection box 8 to the strip-shaped notch 801 on the top wall of the collection box 8, so that the colloid falls into the collection box 8 through the strip-shaped notch 801, so as to facilitate the collection of the colloid.

[0021] In one embodiment of the present invention, a support ring 303 is fixedly connected to the second end of the roller 3 via a connecting rod 302, and the collection box 8 is rotatably connected to the roller 3 through the support ring 303. A horizontal baffle 803 extending radially along the roller 3 is fixedly connected to the collection box 8 near the second end of the roller 3.

[0022] In this solution, by setting a horizontal baffle 803, the colloid floating on the water surface is prevented from overflowing the roller 3 due to the flow of water, thus preventing the colloid from adhering to the conveyor belt 6 outside the roller 3. This would cause the colloid to adhere to the magnetic material again during the conveying process, requiring secondary cleaning.

[0023] In one embodiment of the present invention, the scraper 802 is arranged in a mesh pattern. The scraper 802 can restrict the colloid from passing through the scraper 802 and can allow water to pass through the scraper 802. An elastic brush strip 804 is fixedly arranged on the scraper 802 near the roller 3. The elastic brush strip 804 is spirally arranged along the scraper 802. The gap between the elastic brush strip 804 and the roller 3 is smaller than the height of the magnetic material.

[0024] In this design, after the magnetic material is immersed in the roller 3, the rotation of the roller 3 causes the magnetic material to move due to friction. However, the range of movement is limited. This design incorporates an elastic brush strip 804, which allows the magnetic material to move during the rotation of the roller 3. Once the magnetic material deforms the elastic brush strip 804 under gravity, it can scrape off the adhesive on the surface of the magnetic material through the gap between the elastic brush strip 804 and the roller 3, improving the degumming efficiency. Furthermore, during the forward rotation of the roller 3, the spirally arranged elastic brush strip 804 assists the magnetic material in moving towards the first end of the roller 3, further restricting the magnetic material from detaching from the second end of the roller 3. During the reverse rotation of the roller 3, the spirally arranged elastic brush strip 804 assists the magnetic material in moving towards the second end of the roller 3, preventing the magnetic material from being unable to move to the spiral blade 301.

[0025] In one embodiment of the present invention, a plurality of air pipes 9 are fixedly connected inside the water storage tank 2 and arranged around the lower half of the roller 3. The air pipes 9 extend out of the water storage tank 2 and are fixedly connected to an inflation mechanism (not shown in the figure). The inflation mechanism is a conventional technical means in the art and will not be described in detail here.

[0026] In this scheme, during the degumming process, gas is injected into the air pipe 9 through the air inflation mechanism to form bubbles, which can accelerate the disturbance of the water body and further accelerate the degumming efficiency.

[0027] A cleaning method for a magnetic material degumming and cleaning machine includes the following steps: S1: Start the heater 201 through the control box 7 to heat the cleaning water in the water storage tank 2 to the preset temperature; S2: The magnetic material to be cleaned is poured into the drum 3 through the feed plate 5. The drive mechanism 4 is controlled by the control box 7 to drive the drum 3 to rotate in the forward direction, so that the drum 3 carries the magnetic material to be cleaned into the drum 3 and continuously agitates it. The spiral blades 301 inside the drum 3 prevent the magnetic material from falling from the feed end of the drum 3. When the magnetic material enters the drum 3 through the feed plate 5, the buoyancy of the water can prevent the magnetic material from hitting the inner wall of the drum 3, reducing collision damage. Moreover, the weight of the magnetic material is greater than the buoyancy of the water, so as to ensure that the magnetic material can fall onto the inner wall of the drum 3. S3: After the preset cleaning time, the drive mechanism 4 is controlled by the control box 7 to drive the drum 3 to rotate in the opposite direction. The spiral blades 301 push the magnetic material to the discharge end of the drum 3 as the drum 3 rotates in the opposite direction, so that the magnetic material falls onto the conveyor belt 6. S4: The cleaned magnetic material is transported to the discharge port by the conveyor belt 6, so that the magnetic material can enter the ultrasonic cleaning line, drying line and other subsequent processing equipment through the discharge port to complete the entire degumming and cleaning process.

[0028] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
