Description
Technical Field
[0001] This utility model relates to the field of mask production technology, specifically to a material grading and recycling device for mask production. Background Technology
[0002] A face mask is a protective device that covers the mouth and nose, typically composed of non-woven fabric, meltblown fabric, nose bridge strips, and ear loops. Through its multi-layered filtration structure, it blocks droplets, dust, and pathogens. The production process mainly includes raw material preparation, electrostatic electret treatment of meltblown fabric, multi-layer material lamination, cutting and shaping, cutting and welding of nose bridge strips and ear loops, sterilization, quality inspection, and packaging. The entire process must be completed in a cleanroom to ensure hygiene standards. During the cutting and trimming process, a lot of scraps (such as fabric scraps, fabric chips, nose bridge strip fragments, and ear loop fragments) are generated. To improve resource utilization, these scraps need to be graded and recycled, requiring mask production material grading and recycling equipment. Existing mask production material grading and recycling equipment mostly consists of a magnetic separator, a baffle, and an air extraction system. The magnetic separator removes metal nose bridge strip fragments from the scraps, and the baffle... This device is used to separate fabric scraps and debris. When scraps pass under the magnetic separator, the separator generates a magnetic force that attracts the metal nose bridge strip. The remaining scraps enter the separation chamber, where the exhaust fan in the negative pressure system operates, generating suction. Larger fabric scraps are blocked by the baffle, while smaller debris can pass through the baffle, thus separating the fabric scraps and debris and achieving graded recycling. In traditional mask production material grading and recycling equipment, when scraps pass under the magnetic separator, the metal nose bridge strip is magnetically attracted upwards. During this process, some fabric scraps and debris are also carried away by the metal nose bridge strip and are drawn away by the magnetic separator, requiring secondary sorting of the recycled metal nose bridge strip. When separating fabric scraps and debris through the baffle, the fabric scraps and debris easily adhere to the surface of the baffle, which affects the baffle's passability over time. Therefore, we propose a material grading and recycling device for mask production. Utility Model Content
[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a material grading and recycling device for mask production. This device includes a grading mechanism that uses vibration to initially separate fabric pieces and debris from the metal nose bridge strip. Then, the metal nose bridge strip is quickly recycled through the adsorption of a permanent magnet roller and the scraping of a scraper, avoiding secondary sorting of the metal nose bridge strip. Simultaneously, the rotation of two sets of scrapers can quickly remove scrap material adhering to the surface of the baffle, improving the baffle's passability and thus increasing the efficiency of scrap material grading and recycling. This effectively solves the problems in the prior art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a material grading and recycling device for mask production, comprising a recycling shell and a grading mechanism; Recyclable outer shell: It has a partition at the lower middle part of its interior; The grading mechanism includes a permanent magnet roller, a rubber block, a scraper, a discharge plate, a vibration assembly, and a grading assembly. The permanent magnet roller is rotatably connected to the middle of the front side inside the recycling shell. The rubber block is located on the upper part of the outer surface of the permanent magnet roller. The discharge plate is located on the rear side of the middle inside the recycling shell, with its lower middle part fixedly connected to the upper end of the partition. The scraper is located on the front side of the upper end of the discharge plate, with the front end of the scraper in contact with the outer surface of the permanent magnet roller and the rubber block, providing a basis for the adsorption and recycling of the metal nose strip. The vibration assembly is located at the upper part inside the recycling shell, and the grading assembly is located at the lower part inside the recycling shell. The grading mechanism uses vibration to initially separate the cloth and debris from the metal nose strip. Then, the metal nose strip is quickly recycled by the adsorption of the permanent magnet roller and the scraping of the scraper, avoiding secondary sorting of the metal nose strip. At the same time, the rotation of the two sets of scrapers can quickly scrape off the scraps attached to the surface of the baffle, improving the passage of the baffle and thus improving the grading and recycling efficiency of the scraps.
[0005] Furthermore, the vibration assembly includes spring rubber seats, a vibrating plate, and a vibration motor. The spring rubber seats are all set inside the upper part of the recycling shell by angle iron. A vibrating plate is set between the upper ends of the four spring rubber seats. The front end of the vibrating plate is vertically adjacent to the permanent magnet roller. The vibration motor is set in the middle of the lower end of the vibrating plate. The input end of the vibration motor is electrically connected to an external power source to provide a vibration effect for the scraps, so that the cloth pieces and debris are initially separated from the metal nose strip.
[0006] Furthermore, the grading component includes a baffle, a filter, a rotating shaft, a scraper blade 1, a scraper blade 2, and a motor. The baffle is located inside the partition, in the middle front side. The filter is located in the lower middle of the rear side wall of the recycling shell. The rotating shaft is rotatably connected to the lower middle of the inside of the recycling shell. Scraper blade 1 is located on the middle of the outer surface of the rotating shaft, with its rear end fitting against the front end of the baffle. Scraper blade 2 is located on the rear side of the outer surface of the rotating shaft, with its rear end fitting against the front end of the filter. Motor 1 is located in the lower middle of the front side of the recycling shell. The input end of motor 1 is electrically connected to the output end of a microcontroller. The rear end of the output shaft of motor 1 is fixedly connected to the front end of the rotating shaft. This allows for the rapid scraping of scrap materials adhering to the surfaces of the baffle and filter, improving the separation efficiency of scrap materials.
[0007] Furthermore, the grading mechanism also includes a mounting rod and baffles. The mounting rod is located at the upper front end of the inner side of the recycling shell, and the baffles are evenly distributed at the lower end of the outer surface of the mounting rod. The lower ends of the baffles are all installed in conjunction with the outer surfaces of the permanent magnet roller and the rubber block to prevent cloth pieces and debris from being mixed inside the metal nose strip.
[0008] Furthermore, the grading mechanism also includes a second motor, which is located at the front end of the right middle part of the recycling shell. The input end of the second motor is electrically connected to the output end of the microcontroller, and the left end of the output shaft of the second motor is fixedly connected to the right end of the permanent magnet roller, providing a basis for the collection of the metal nose strip.
[0009] Furthermore, it also includes an air inlet and an exhaust duct. The air inlet is evenly distributed on the upper front side of the recycling shell, and the exhaust duct is located on the lower rear side of the recycling shell to provide a suction effect for the separation of cloth pieces and debris.
[0010] Furthermore, it also includes a collection trough, which is inserted into the front and rear sides of the lower end of the recycling shell to provide a basis for the collection of cloth pieces and debris.
[0011] Furthermore, it also includes a microcontroller, which is located in the middle right side of the recycling shell. The input terminal of the microcontroller is electrically connected to an external power source to provide control for the graded recycling of mask materials.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This material grading and recycling equipment for mask production has the following advantages: 1. The vibration of the vibrating plate moves the small, heavy metal nose strips to the bottom of the scrap pile, facilitating their subsequent collection. Magnetic force quickly attracts the metal nose strips to the surface of the permanent magnet roller. Baffles prevent larger pieces of fabric and debris from crossing the permanent magnet roller. Combined with the obstruction of the scraper and the non-magnetic nature of the rubber block, the metal nose strips in the scrap pile of mask production can be collected quickly, completing the graded recycling of the metal nose strips.
[0013] 2. By rotating scraper one and scraper two, the scraps from mask production attached to the front end of the baffle and filter can be quickly scraped off, preventing scraps from adhering to the surface of the baffle and filter and affecting their passability. This allows debris to pass through the baffle quickly, improving the efficiency of graded recycling of the baffle and filter. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-4 This embodiment provides a technical solution: a material grading and recycling device for mask production, including a recycling shell 1 and a grading mechanism 3; The recycling shell 1 has a partition 2 at the lower middle part of its interior, and also includes an air inlet 4 and an exhaust duct 5. The air inlets 4 are evenly distributed on the upper front side of the recycling shell 1 for air intake. The exhaust duct 5 is located at the lower rear side of the recycling shell 1. The rear end of the exhaust duct 5 is connected to an external exhaust fan through a connecting pipe. The exhaust duct 5 is funnel-shaped, which can make the airflow more evenly backward and provide a suction effect for the separation of cloth pieces and debris. It also includes a collection trough 6, which is inserted into the front and rear sides of the lower interior of the recycling shell 1. The collection trough 6 is drawer-shaped and can be quickly pulled out for the collection of scraps, providing a basis for the collection of cloth pieces and debris. Grading mechanism 3 includes a permanent magnet roller 31, a rubber block 32, a scraper 33, a discharge plate 34, a vibration assembly 35, and a grading assembly 36. The permanent magnet roller 31 is rotatably connected to the middle of the front side inside the recycling shell 1 and is magnetic. The rubber block 32 is disposed on the upper part of the outer surface of the permanent magnet roller 31 and is non-magnetic. The discharge plate 34 is disposed on the middle rear side inside the recycling shell 1. The lower middle part of the discharge plate 34 is fixedly connected to the upper end of the partition 2. The rear end of the discharge plate 34 is inclined downward to facilitate discharge. The scraper 33 is disposed on the upper front side of the discharge plate 34. The front end of the scraper 33 is in contact with the outer surface of the permanent magnet roller 31 and the rubber block 32, providing a basis for the adsorption and recycling of the metal nose strip. The vibration assembly 35 is disposed inside the recycling shell 1. At the upper end, the vibration assembly 35 includes a spring rubber seat 351, a vibration plate 352, and a vibration motor 353. The spring rubber seat 351 consists of a rubber sleeve, a spring inside the rubber sleeve, and mounting seats fixedly connected to the upper and lower ends of the rubber sleeve. The bottom end of the upper mounting seat is fixedly connected to the upper end of the spring, and the upper end of the lower mounting seat is fixedly connected to the lower end of the spring. All spring rubber seats 351 are set inside the upper end of the recycling shell 1 by angle iron. A vibration plate 352 is set between the upper ends of the four spring rubber seats 351. The spring rubber seats 351 absorb and buffer the vibration or impact energy of the equipment by using the elasticity and damping characteristics of the rubber material combined with the supporting effect of the spring. When an external force is applied, the rubber undergoes elastic deformation to slow down the vibration transmission, while the internal molecular friction... The friction generates a damping effect, converting some mechanical energy into heat energy for dissipation. The spring provides rigid support and assists in rebound, ensuring system stability. This combination effectively isolates vibration, reduces noise, and compensates for equipment displacement, and is widely used in industrial machinery vibration reduction. The front end of the vibrating plate 352 is vertically adjacent to the permanent magnet roller 31. The vibrating motor 353 is located in the middle of the lower end of the vibrating plate 352. The input end of the vibrating motor 353 is electrically connected to an external power source to provide vibration for the scrap material, so that the cloth pieces and debris are initially separated from the metal nose strip. The grading component 36 is located inside the lower end of the recycling shell 1. The grading component 36 includes a baffle 361, a filter 362, a rotating shaft 363, a scraper 364, a scraper 365, and a motor 366. The baffle 361 is located inside the partition 2. In the middle front side of the unit, filter screen 362 is located at the lower middle of the rear side wall of the recycling housing 1. A rotating shaft 363 is rotatably connected to the lower middle of the interior of the recycling housing 1. Scraper blade 364 is located at the middle of the outer surface of the rotating shaft 363, with its rear end fitting against the front end of the baffle 361. Scraper blade 365 is located at the rear side of the outer surface of the rotating shaft 363, with its rear end fitting against the front end of the filter screen 362. Motor 366 is located at the lower middle of the front side of the recycling housing 1. The input end of motor 366 is electrically connected to the output end of the microcontroller 7. The rear end of the output shaft of motor 366 is fixedly connected to the front end of the rotating shaft 363. The mesh size of the baffle 361 is much larger than that of the filter screen 362, allowing the filter screen 362 to prevent scrap and debris from entering the interior of the exhaust hopper 5.It can quickly scrape off the scraps attached to the surfaces of the baffle 361 and filter 362, improving the separation efficiency of the scraps. The grading mechanism 3 also includes a mounting rod 37 and baffles 38. The mounting rod 37 is located at the upper front of the inside of the recycling shell 1. The baffles 38 are evenly distributed on the lower end of the outer surface of the mounting rod 37. The lower end of the baffles 38 is installed in conjunction with the outer surface of the permanent magnet roller 31 and the rubber block 32. The baffles 38 are thick rubber sheets. There is a certain gap between the lower end of the baffles 38 and the surface of the permanent magnet roller 31. Flat metal nose bars can pass through, but large pieces of cloth and debris cannot pass through, avoiding the mixing of cloth and debris inside the metal nose bars. The grading mechanism 3 also includes an electric... Motor 39 is located at the front right side of the recycling housing 1. The input of motor 39 is electrically connected to the output of microcontroller 7. The left end of the output shaft of motor 39 is fixedly connected to the right end of permanent magnet roller 31, providing a foundation for the collection of metal nose strips. A grading mechanism 3 is provided, which uses vibration to initially separate cloth pieces and debris from the metal nose strips. Then, the permanent magnet roller 31 adsorbs the metal nose strips, and the scraper 33 quickly removes them, avoiding secondary sorting. Simultaneously, the rotation of two sets of scrapers quickly removes scraps adhering to the surface of the baffle 361, improving the baffle's passability and thus increasing the efficiency of scrap recycling.
[0018] The working principle of the material grading and recycling equipment for mask production provided by this utility model is as follows: When grading and recycling mask production materials, i.e., scraps, the scrap pile is fed into the vibrating plate 352 from the feed inlet by an external conveyor belt. The single-chip microcomputer 7 controls the vibration motor 353 to work, and the vibration motor 353 generates an excitation force, driving the vibrating plate 352 to vibrate. The spring rubber seat 351 provides support for the vibrating plate 352. As the vibrating plate 352 vibrates, the small-volume, high-density metal nose bridge strips in the scrap pile above the vibrating plate 352 slowly move to the bottom of the scrap pile, while the large-volume, low-density cloth pieces and debris remain on top of the scrap pile. As the vibrating plate 352 continues to rotate, the inclined vibrating plate 352 moves the scrap pile... As the metal nose strip is thrown downwards from the front, the microcontroller 7 controls the operation of motor 39. The output shaft of motor 39 drives the permanent magnet roller 31 to rotate. Since the metal nose strip is located below the scrap pile, it is closer to the permanent magnet roller 31 and can be quickly attracted by the magnetic force generated by the permanent magnet roller 31. The baffle 38 below the mounting rod 37 can block larger pieces of cloth and debris, while the flat metal nose strip can pass through the gap between the baffle 38 and the permanent magnet roller 31, preventing pieces of cloth and debris from crossing the permanent magnet roller 31 and avoiding secondary sorting of the metal nose strip. After the metal nose strip is attracted to the surface of the permanent magnet roller 31, as the permanent magnet roller 31 rotates, the metal nose strips attached to the surface of the permanent magnet roller 31 are blocked and scraped off by the scraper 33, and then piled up on the permanent magnet roller 31. Between the magnetic roller 31 and the front end of the scraper 33, the metal nose strip on the surface of the permanent magnet roller 31 is blocked after passing the scraper 33, allowing for the next adsorption operation until the rubber block 32 contacts the scraper 33. The rubber block 32 then loses its magnetic force, and the metal nose strip loses its magnetic adsorption effect, sliding off the surface of the scraper 33 onto the discharge plate 34, and then sliding out of the recycling shell 1, thus collecting the metal nose strip. Simultaneously, the motor 366 and the external exhaust fan also operate. The external exhaust fan draws air from the right side of the partition 2 through the exhaust duct 5, reducing the pressure on the right side of the partition 2. Air then flows to the right side of the partition 2 and is drawn in through the air inlet 4, passing through the baffle 361 and filter 362 before being drawn out by the external exhaust fan. Inside the outer casing 1, a rapidly flowing airflow is generated at the lower end. During this process, the remaining fabric pieces and debris in the scrap pile fall downwards from the front end of the vibrating plate 352. Affected by the airflow, the heavier fabric pieces fall directly into the front collection trough 6, while the lighter debris moves backward with the airflow, passes through the baffle 361, and is blocked by the filter screen 362, thus separating the fabric pieces and debris. After the machine stops, the fabric pieces and debris automatically fall into the corresponding collection trough 6, achieving the collection of fabric pieces and debris. At the same time, the motor 366 drives the rotating shaft 363 to rotate, which in turn drives the scraper blades 364 and 365 to rotate. The scraper blade 364 scrapes off the scrap at the front end of the baffle 361, and the scraper blade 365 scrapes off the scrap on the surface of the filter screen 362.This prevents scrap materials from adhering to the surfaces of the baffle 361 and filter 362, thus affecting their permeability and improving the efficiency of graded recycling of mask scrap materials.
[0019] It is worth noting that the microcontroller 7 disclosed in the above embodiments is an STM8S105K4T6CTR microcontroller, the vibration motor 353 is a MICRO_M3 / 20-S02 vibration motor, the first motor 366 is a CH400 motor, and the second motor 39 is a DKM motor. The microcontroller 7 controls the operation of the vibration motor 353, the first motor 366, and the second motor 39 using methods commonly used in the prior art.
