Description

Technical Field

[0001] This utility model belongs to the field of magnetic adsorption technology for impurity removal, and in particular relates to a magnetic adsorption device for removing impurities from packaging cardboard raw materials. Background Technology

[0002] As a core raw material, the purity of cardboard directly determines the quality, appearance, and performance of the final packaging product. If metallic impurities (such as iron filings or copper slag generated during equipment wear and tear in the production process, or metal particles accidentally mixed in during raw material transportation and storage) are mixed into the cardboard raw material, they will not only damage precision equipment in subsequent processing stages such as cutting, printing, and creasing (e.g., scratching printing rollers or wearing out cutting tools), leading to increased equipment maintenance costs and reduced production efficiency, but also affect the flatness and aesthetics of the packaging product due to residual impurities. In some special fields such as food packaging and pharmaceutical packaging, they may even pose safety hazards and fail to meet relevant industry standards and quality requirements.

[0003] In the existing technology, the main methods for removing impurities from cardboard raw materials in the industry include manual screening, vibration screening and simple magnetic removal. Manual screening relies on operators to identify and remove impurities with their naked eyes, which is not only labor-intensive and inefficient, but also makes it difficult to detect small metal fragments, and the accuracy of impurity removal cannot be guaranteed. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a magnetic adsorption device for removing impurities from packaging cardboard raw materials.

[0005] A magnetic suction device for removing impurities from packaging cardboard raw materials includes: a box body, a feeding structure provided on the box body, and a first connecting plate and a second connecting plate provided in the inner cavity of the box body; A material flow channel is formed between the first connecting plate and the second connecting plate. A partition plate is provided on one side of the second connecting plate, which divides the inner cavity of the box into a material receiving cavity and an impurity receiving cavity, and the material receiving cavity is connected to the material flow channel. A rotating rod is rotatably mounted inside the box and is located within the material flow channel. A rotary drive device is provided on one side of the box, and the drive end of the rotary drive device movably passes through the box and is connected to the rotating rod. A sleeve is detachably mounted on the outer periphery of the rotating rod through a plug-in structure. Several mounting ports are provided on one side of the sleeve, and magnetic suction components are installed in each of the mounting ports. A scraping structure is provided at the top of the second connecting plate, and the outer surface of the sleeve is in contact with the scraping structure to scrape magnetic impurities on the outer periphery of the sleeve into the impurity receiving cavity.

[0006] Furthermore, the plug-in structure includes a mounting hole on one side of the housing, two plug-in slots on one side of the sleeve, and two plug rods on the outer periphery of the rotating rod, with the two plug rods matching the corresponding plug-in slots.

[0007] Furthermore, a sealing plug is provided at the mounting hole.

[0008] Furthermore, the two ends of the sleeve are respectively in contact with the interior of the housing and one side of the sealing plug.

[0009] Furthermore, the magnetic attractant is a magnetic rod.

[0010] Furthermore, the scraping structure includes a scraper disposed on the top of the second connecting plate, one end of the scraper being in contact with the outer periphery of the sleeve, and the end of the scraper extending through an arcuate portion to the side of the second connecting plate away from the first connecting plate.

[0011] Furthermore, the bottom of the box is provided with two discharge pipes, which are respectively connected to the material receiving cavity and the impurity receiving cavity.

[0012] Furthermore, electromagnetic valves are installed on the outer periphery of both discharge pipes.

[0013] Furthermore, the first connecting plate, the second connecting plate, and the partition plate are all inclined.

[0014] Furthermore, the feeding structure includes a feeding box disposed on the top of the box, one end of which extends movably through the box and into the box body. The top of the feeding box is provided with a feeding port, and the bottom side of the feeding box is provided with a discharging port, which is connected to the material flow channel.

[0015] Compared with existing technologies, the magnetic adsorption device for removing impurities from packaging cardboard raw materials of this utility model has the following advantages: The material flow channel formed by the first and second connecting plates allows the packaging cardboard raw material to flow in a directional manner, ensuring that the raw material passes through the sleeve area around the rotating rod throughout the entire process. The magnetic attraction component inside the sleeve can attract metal impurities in the raw material, preventing impurities from being mixed into subsequent processing stages and ensuring the purity of the cardboard raw material. At the same time, the partition plate divides the inner cavity of the box into a material receiving cavity and an impurity receiving cavity, realizing the physical separation of the pure raw material and impurities after impurity removal, preventing secondary mixing. The rotation drive device drives the rotating rod and sleeve to rotate, so that the magnetic attraction component can continuously contact the flowing raw material, avoiding impurity omissions caused by local magnetic saturation and improving impurity removal efficiency. The scraping structure at the top of the second connecting plate contacts the outer surface of the sleeve, which can scrape off the metal impurities adsorbed on the sleeve in real time, allowing the impurities to fall into the impurity receiving cavity without stopping the machine to clean the magnetic attraction component, ensuring continuous operation of the device and reducing production interruption time.

[0021] Reference Figures 1-5 A magnetic suction device for removing impurities from packaging cardboard raw materials includes: a box body 1, a feeding structure provided on the box body 1, and a first connecting plate 2 and a second connecting plate 3 provided in the inner cavity of the box body 1; A material flow channel 21 is formed between the first connecting plate 2 and the second connecting plate 3. A partition plate 4 is provided on one side of the second connecting plate 3. The partition plate 4 divides the inner cavity of the box 1 into a material receiving cavity 5 and an impurity receiving cavity 6. The material receiving cavity 5 is connected to the material flow channel 21. A rotating rod 7 is rotatably installed inside the housing 1. The rotating rod 7 is located inside the material flow channel 21. A rotary drive device 20 is provided on one side of the housing 1. The drive end of the rotary drive device 20 movably passes through the housing 1 and is connected to the rotating rod 7. A sleeve 8 is detachably installed on the outer periphery of the rotating rod 7 through a plug-in structure. A plurality of mounting ports 9 are provided on one side of the sleeve 8. A magnetic suction component 10 is installed in each of the mounting ports 9. A scraping structure is provided at the top of the second connecting plate 3, and the outer surface of the sleeve 8 is in contact with the scraping structure to scrape magnetic impurities on the outer periphery of the sleeve 8 into the impurity receiving cavity 6.

[0022] In use, the material flow channel 21 formed by the first connecting plate 2 and the second connecting plate 3 allows the packaging cardboard raw material to flow in a directional manner, ensuring that the raw material passes through the sleeve 8 area around the rotating rod 7 throughout the entire process. The magnetic suction component 10 inside the sleeve 8 can adsorb metal impurities in the raw material, preventing impurities from being mixed into subsequent processing stages and ensuring the purity of the cardboard raw material. At the same time, the partition plate 4 divides the inner cavity of the box 1 into a material receiving cavity 5 and an impurity receiving cavity 6, realizing the physical separation of the pure raw material and impurities after impurity removal, preventing secondary mixing. The rotation drive device 20 drives the rotating rod 7 and the sleeve 8 to rotate, so that the magnetic suction component 10 can continuously contact the flowing raw material, avoiding the omission of impurities due to local magnetic saturation and improving the impurity removal efficiency. The scraping structure at the top of the second connecting plate 3 contacts the outer surface of the sleeve 8, which can scrape off the metal impurities adsorbed on the sleeve 8 in real time, allowing the impurities to fall into the impurity receiving cavity 6 without stopping the machine to clean the magnetic suction component 10, ensuring continuous operation of the device and reducing production interruption time.

[0023] In the example of this application, the plug-in structure includes a mounting hole 11 opened on one side of the housing 1, two plug-in slots 12 are provided on one side of the sleeve 8, and two plug rods 22 are provided on the outer periphery of the rotating rod 7, with the two plug rods 22 being adapted to the corresponding plug-in slots 12.

[0024] As a preferred example of this utility model, the two insert rods 22 on the outer periphery of the rotating rod 7 are adapted to the two insertion slots 12 on one side of the sleeve 8. When installing the sleeve 8, simply align the insertion slots 12 with the insert rods 22 and insert them to complete the fixation. When disassembling, the axially sliding sleeve 8 can be pulled outward to separate from the rotating rod 7, which enables the rapid assembly and disassembly of the sleeve 8 and improves the efficiency of device maintenance and parts replacement.

[0025] In the example of this application, a sealing plug 13 is provided at the mounting hole 11.

[0026] As a preferred example of this utility model, the sealing plug 13 at the mounting hole 11 on one side of the box body 1 can effectively seal the gap between the mounting hole 11 and the sleeve 8, preventing fine raw material powder from leaking to the outside from the gap of the mounting hole 11 during the flow of the packaging cardboard raw material in the box body 1, avoiding raw material waste and pollution of the working environment; it can also prevent external dust and impurities from entering the box body 1 through the mounting hole 11, preventing external impurities from mixing into the raw material and affecting the purity of the raw material, and ensuring the quality of the raw material after impurity removal.

[0027] In the example of this application, the two ends of the sleeve 8 are respectively in contact with the interior of the housing 1 and one side of the sealing plug 13.

[0028] As a preferred example of this utility model, the two ends of the sleeve 8 are respectively abutted against the inside of the housing 1 and one side of the sealing plug 13, forming a bidirectional limit, which can effectively restrict the movement of the sleeve 8 in the axial direction of the rotating rod 7, prevent the contact position between the sleeve 8 and the scraping structure from changing due to axial displacement during rotation, ensure that the scraping structure can always contact the outer periphery of the sleeve 8, and guarantee the stability of the impurity scraping effect.

[0029] In the example of this application, the magnetic attractor 10 is a magnetic rod.

[0030] As a preferred example of this utility model, the magnetic suction component 10 uses a magnetic rod. The magnetic rod has a strong magnetic adsorption capacity, which can efficiently adsorb metal impurities of different sizes and shapes in the packaging cardboard raw materials. Whether it is a small metal shaving or a slightly larger metal particle, it can be stably adsorbed, thereby improving the device's capture efficiency for metal impurities and ensuring more thorough removal of impurities from the raw materials.

[0031] In the example of this application, the scraping structure includes a scraper 14 disposed on the top of the second connecting plate 3, one end of the scraper 14 being in contact with the outer periphery of the sleeve 8, and the end of the scraper 14 extending through the arcuate portion 23 to the side of the second connecting plate 3 away from the first connecting plate 2.

[0032] As a preferred example of this utility model, one end of the scraper 14 in the scraping structure is in contact with the outer periphery of the sleeve 8. When the sleeve 8 rotates, the scraper 14 can continuously scrape the outer periphery of the sleeve 8 to completely scrape off the metal impurities adsorbed on the surface of the sleeve 8, avoiding the accumulation of impurities on the surface of the sleeve 8 and affecting the subsequent adsorption effect of the magnetic adsorption component 10, ensuring that the sleeve 8 always maintains a clean magnetic adsorption surface and maintaining the device's efficient impurity removal capability.

[0033] In the example of this application, the bottom of the box 1 is provided with two discharge pipes 15, which are respectively connected to the material receiving cavity 5 and the impurity receiving cavity 6.

[0034] As a preferred example of this utility model, the two discharge pipes 15 at the bottom of the box 1 are connected to the material receiving cavity 5 and the impurity receiving cavity 6, respectively. The purified raw material after impurity removal can be quickly discharged through the discharge pipe 15 of the corresponding material receiving cavity 5, and the collected impurities can be centrally discharged through the discharge pipe 15 of the corresponding impurity receiving cavity 6. There is no need to open the box 1 for manual cleaning, which simplifies the discharge process of materials and impurities and improves the work efficiency. The two discharge pipes 15 realize the separate discharge of raw materials and impurities, which facilitates the subsequent processing of the purified raw materials and also facilitates the centralized recycling of impurities (such as the recycling and reuse of metal impurities).

[0035] In the example of this application, solenoid valves 16 are provided on the outer periphery of both discharge pipes 15.

[0036] As a preferred example of this utility model, the electromagnetic valves 16 installed on the outer periphery of the two discharge pipes 15 can be electrically controlled to open and close the valves. The operator can flexibly control the discharge time and discharge speed according to the amount of raw material stored in the material receiving cavity 5 inside the box 1 and the amount of impurities accumulated in the impurity receiving cavity 6, so as to avoid waste caused by premature discharge of raw materials or impurities.

[0037] In the example of this application, the first connecting plate 2, the second connecting plate 3, and the partition plate 4 are all inclined.

[0038] As a preferred example of this utility model, the first connecting plate 2, the second connecting plate 3, and the partition plate 4 are all inclined. The inclined structure utilizes gravity to guide the packaging cardboard raw material to flow quickly in the material flow channel 21, shortening the residence time of the raw material in the device and improving the material processing efficiency. The inclined partition plate 4 can also guide the scraped-off impurities to slide quickly into the impurity receiving cavity 6, avoiding the accumulation of impurities on the surface of the partition plate 4 and ensuring that the impurities are collected smoothly.

[0039] In the example of this application, the feeding structure includes a feeding box 17 disposed on the top of the box body. One end of the feeding box 17 extends movably through the box body 1 into the box body 1. The top of the feeding box 17 is provided with a feeding port 18, and the bottom side of the feeding box 17 is provided with a discharge port 19, which is connected to the material flow channel 21.

[0040] As a preferred example of this utility model, the feeding box 17 in the feeding structure is provided with a feeding port 18 at the top and a discharging port 19 at the bottom, and the discharging port 19 is connected to the material flow channel 21. After the raw material enters the feeding box 17 through the feeding port 18, it can form a certain buffer storage in the feeding box 17, and then be stably and evenly transported to the material flow channel 21 through the discharging port 19. This avoids uneven feeding, material interruption or congestion when the raw material is poured in directly, ensuring stable feeding of the device and maintaining the continuity of subsequent impurity removal operations.

[0041] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
