Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a high-efficiency processing and screening device for medical antibacterial soft masterbatch. Background Technology

[0002] A masterbatch screening device is a piece of equipment used to screen masterbatch. Its main function is to screen the masterbatch according to its particle size, quality or other characteristics to ensure that the obtained masterbatch meets specific standards or requirements.

[0003] Nonwoven fabrics are commonly used materials in hospitals, widely used in medical staff's daily work clothes, isolation gowns, patient isolation sheets, quilt covers, nursing supplies, dressings, etc. These applications require nonwoven fabrics to have excellent and long-lasting antibacterial properties, as well as good softness and comfort. Therefore, nonwoven fabrics need to use masterbatches with both antibacterial and soft properties as raw materials. Equally important, as medical materials, there are strict dust restrictions on masterbatches. However, existing screening devices have difficulty screening antibacterial and soft nonwoven fabric raw material masterbatches that meet medical requirements. They cannot effectively remove impurities and dust raised in the screening chamber during the screening process, causing impurities to interfere with the masterbatch screening process, resulting in screening errors and making it difficult for the masterbatches to meet medical requirements.

[0004] This high-efficiency processing and screening device for medical antibacterial and soft masterbatch is a specialized equipment for producing medical antibacterial and soft masterbatch. While ensuring the antibacterial properties and softness of the masterbatch, it can effectively remove impurities and dust, meeting the requirements of medical nonwoven fabric raw materials. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that cannot effectively remove impurities and dust raised inside the screening chamber during the screening process, which leads to interference with the masterbatch screening process and causes screening errors. Therefore, this invention proposes a medical antibacterial soft masterbatch high-efficiency processing and screening device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency processing and screening device for medical antibacterial soft masterbatch includes:

[0008] A support frame, the top of which is rectangular and fixedly equipped with four springs, the top of which is fixedly equipped with the same box, the top of which is hinged to a box cover, and the bottom of which is fixedly equipped with a vibrator;

[0009] The suction assembly is located on the lid and is used to remove impurities and dust stirred up by vibration.

[0010] In one possible design, the suction assembly includes a dust collection box fixedly mounted on the top of the box cover. Both sides of the dust collection box are fixedly connected to connecting pipes. The two connecting pipes pass through the top of the box cover and extend to its bottom. Filter screens are fixedly installed inside the bottom ends of the two connecting pipes. Two filter cartridge holders are symmetrically sealed and inserted into the top of the dust collection box. Filter cartridges can be detachably mounted on both filter cartridge holders. A fan is fixedly connected to one side of the dust collection box.

[0011] In one possible design, a first screen is detachably installed inside the box; a second screen is detachably installed below the first screen; a third screen is detachably installed below the second screen; a slag discharge trough is provided inside the box below the third screen; a first discharge port is fixedly installed on one side of the box at the location of the first screen; a second discharge port is fixedly installed on one side of the box at the location of the second screen; a third discharge port is fixedly installed on one side of the box at the location of the third screen; and a slag discharge pipe is fixedly installed at the bottom of the box, and the slag discharge pipe is connected to the slag discharge trough.

[0012] In one possible design, two connecting frames are symmetrically arranged on both sides of the support frame. The top of each of the four connecting frames is threaded with a screw. The top of each of the four screws is fixedly provided with an adjusting nut. The bottom of each of the four screws is rotatably provided with a support pad. The bottom of each of the four support pads is fixedly provided with a rubber anti-slip pad.

[0013] In one possible design, the top of the box cover is fixedly connected to a feed inlet, the top of the feed inlet is hinged to a cover, a handle is fixedly provided on one side of the cover, and the box body and the box cover are locked together by a snap fastener.

[0014] In one possible design, the bottom of the support frame is rectangularly fixed with four omnidirectional brake wheels.

[0015] In this application, upon initial use, the screening device is first moved to the desired position using the universal brake wheels. The position is then confirmed by the locking function on the universal brake wheels. Next, the device is powered on. Then, depending on the ground conditions, the adjusting nut is rotated. As the nut rotates, it causes the screw to move downwards on the connecting frame. As the screw moves downwards, the support pad on it approaches and eventually makes close contact with the ground, thus supporting the device. This allows for flexible leveling of the device according to actual work requirements, and the stability of the device is ensured by rubber anti-slip pads. This ensures the stability of the device in different working environments and improves the safety of the entire operation process.

[0016] Then, open the cap and pour the medical antibacterial soft masterbatch to be screened into the chamber through the feed inlet. Seal the feed inlet by rotating the cap with the handle, and start the vibrator to vibrate the chamber, causing the masterbatch inside to be screened. During vibration, the masterbatch will pass through screens No. 1, No. 2, and No. 3 for grading. Masterbatch of different sizes will be discharged through outlets No. 1, No. 2, and No. 3 respectively, and then collected for further processing as needed. Simultaneously, start the exhaust fan, and the suction assembly will begin working, sucking impurities and dust stirred up by the vibration into the dust collection box through the connecting pipe. A filter screen prevents the masterbatch from being sucked into the connecting pipe, and the filter element filters out the sucked-in impurities and dust before clean air is discharged, while the impurities and dust remain in the dust collection box. During the screening process, the vibration frequency of the vibrator and the suction power of the exhaust fan can be adjusted as needed to achieve the best screening effect.

[0017] After screening, turn off the vibrator and exhaust fan, unfasten the buckle and open the box cover, check if there is any blockage or damage to each screen, and clean or replace it in time if necessary. Open the slag discharge pipe to discharge the impurities and fine particles in the slag discharge trough. Then pull out the filter element frame, clean the impurities and dust in the dust collection box, and selectively clean and replace the filter elements as needed to ensure that the suction components are unobstructed.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, by setting up a suction component, when the exhaust fan is working, it sucks the impurities and dust raised in the box due to vibration into the dust collection box, and then discharges them after being filtered by the filter element. This allows it to effectively remove the impurities and dust raised in the box during operation, prevent impurities from interfering with the masterbatch screening process, improve the accuracy and efficiency of screening, and reduce screening errors caused by impurities.

[0020] In this invention, the screw, adjusting nut, and support pad are configured so that the length of the screw can be adjusted by rotating the adjusting nut, thereby adjusting the level of the support pad to adapt to different working environments. This ensures the stability of the device under different working environments and improves the safety of the entire operation process.

[0021] This invention, through the design of a suction component, can effectively remove impurities and dust raised inside the chamber during operation, preventing impurities from interfering with the masterbatch screening process, improving the accuracy and efficiency of screening, and reducing screening errors caused by impurities.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Because antibacterial and soft masterbatches are used in medical applications, there are strict restrictions on dust, making screening difficult. This technical solution is designed based on this consideration. Medical applications not only have high requirements for antibacterial properties, but more importantly, dust is not allowed. Therefore, as a raw material masterbatch for medical nonwoven fabrics, the device of this patent must be used to meet these requirements. This embodiment: Refer to Figure 1-4 A screening device, comprising:

[0030] The support frame 1 has a box 3 fixedly connected to its top by four springs 2. A vibrator 301 (model ZFB / LZF-3) is fixedly installed at the bottom of the box 3. When the vibrator 301 is working, it will generate vibration and, together with the springs 2, cause the masterbatch in the box 3 to be vibrated, thereby achieving the screening effect.

[0031] In the medical field, due to the high standards of antibacterial properties and strict dust restrictions, screening nonwoven fabric raw material masterbatches becomes particularly difficult. Considering these stringent conditions, a lid 4 is hinged to the top of the box 3. The lid 4 is equipped with a suction component to ensure that the produced medical nonwoven fabric raw material masterbatches can meet the high antibacterial performance requirements while effectively avoiding dust generation. The suction component includes a dust collection box 5 fixed to the top of the lid 4. A connecting pipe 6 is fixedly connected to each side of the dust collection box 5. The connecting pipe 6 passes through the lid 4 and extends to its bottom. A filter screen 601 is installed inside the bottom of each connecting pipe 6. To prevent masterbatch from being sucked into the connecting pipe 6, the top of the dust collection box 5 is equipped with two filter cartridge frames 7, each of which is detachably equipped with a filter cartridge for filtering impurities and dust. A blower 8 is fixedly connected to one side of the dust collection box 5. When the blower 8 (model: CX-100) is working, it sucks the impurities and dust that are raised due to vibration inside the box 3 into the dust collection box 5, and then discharges them after being filtered by the filter cartridge. This allows it to effectively remove impurities and dust raised inside the box 3 during operation, preventing impurities from interfering with the masterbatch screening process, improving the accuracy and efficiency of screening, and reducing screening errors caused by impurities.

[0032] The box body 3 is equipped with three layers of detachable screens, namely screen 9, screen 10, and screen 11, which are used to screen the masterbatch according to different sizes. On one side of the box body 3, there are discharge ports 13, 14, and 15 corresponding to the screens, which facilitates the collection of screened masterbatch. At the bottom of the three layers of screens, there is also a slag discharge trough 12 inside the box body 3, which is used to collect impurities and fine particles that cannot pass through the screen. The slag discharge trough 12 is connected to the slag discharge pipe 16 fixed at the bottom of the box body 3, which facilitates the discharge of impurities.

[0033] To adjust the level of the device and improve its stability, two connecting frames 17 are respectively provided on both sides of the support frame 1. Each connecting frame 17 has a threaded screw 18 connected to its top. By rotating the adjusting nut 19, the length of the screw 18 can be adjusted, thereby adjusting the level of the support pad 20 to adapt to different working environments. This ensures the stability of the device under different working environments and improves the safety of the entire operation process. The bottom of the support pad 20 is provided with a rubber anti-slip pad to increase the stability of the device and also to increase a certain cushioning effect.

[0034] This application can be used in the field of efficient processing and screening equipment for medical antibacterial soft masterbatch, and can also be used in other fields applicable to this application.

[0036] Based on Embodiment 1, Embodiment 2 further includes: a medical antibacterial soft masterbatch high-efficiency processing and screening device, which is applied to the technical field of medical antibacterial soft masterbatch high-efficiency processing and screening device. The top of the box cover 4 is provided with a feed port 401 for adding the masterbatch to be screened into the box body 3. The top of the feed port 401 is hinged with a cover 402 for closing the feed port 401 to prevent impurities from entering. A handle is provided on one side of the cover 402 for easy opening and closing. The box body 3 and the box cover 4 are locked together by a buckle to ensure the airtightness during the screening process.

[0037] To facilitate the movement and fixation of the device, the bottom of the support frame 1 is also equipped with four universal brake wheels 21. When it is necessary to move the device, the universal brake wheels 21 can be unlocked and the device can be moved by pushing it. When it is necessary to fix the device, the universal brake wheels 21 can be locked to keep the device stable and stationary.

[0038] However, as is well known to those skilled in the art, the working principles and wiring methods of the vibrator 301 and the exhaust fan 8 are commonplace and are conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
