Description

Technical Field

[0001] This invention belongs to the field of nonwoven fabric processing technology, specifically a multi-layer composite antibacterial nonwoven filter material integrated processing device. Background Technology

[0003] However, existing technologies often have the following drawbacks: during the processing of existing multi-layer composite antibacterial non-woven filter materials, problems such as deviation, slippage, and misalignment easily occur when the multi-layer non-woven fabrics are stacked, resulting in poor alignment accuracy, poor thickness uniformity, and easy delamination of the finished product, which affects production stability and the overall structural quality of the filter material.

[0004] Therefore, the present invention provides an integrated processing device for multi-layer composite antibacterial non-woven filter materials. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The multi-layer composite antibacterial non-woven filter material integrated processing device of the present invention includes a frame, a processing table is installed inside the frame, a flexible dot matrix positioning mechanism is installed in the middle of the processing table, a vertical plate is installed at the tail end of the processing table, a winding mechanism is installed on the outer surface of the vertical plate, a warm drying mechanism is installed on the top of the frame, and a monitoring mechanism is installed at the edge of the upper surface of the processing table. The flexible dot matrix positioning mechanism includes a cover plate, which is installed on the outside of the processing table in the middle. The surface of the cover plate has several holes, and an air pipe is inserted into the port of the hole. A filter is installed inside the hole. An A transmission pipe is fixedly connected to the outer surface of the air pipe. A vacuum adsorption pump is installed at one end of the A transmission pipe. The outer surface of the vacuum adsorption pump is installed at the bottom of the processing table.

[0007] As a further optimization, the winding mechanism includes a servo motor, the outer surface of which is fixedly mounted on the outer surface of the upright plate. The output end of the servo motor is splinedly connected to a winding roller. An air duct is embedded on the surface of the winding roller. A transmission pipe B is fixedly connected inside the air duct through a connecting pipe. One end of the transmission pipe B is fixedly connected to a blower A, and one end of the blower A is fixedly connected to an air inlet pipe A.

[0008] As a further optimization, the heating and drying mechanism includes a housing, an electric push rod is installed in the middle of the upper surface of the housing, connecting pipes are fixedly connected to both sides of the upper surface of the housing, a C-transmission pipe is fixedly connected to the outer surface of the connecting pipe, and a B-blower is fixedly connected to one end of the C-transmission pipe.

[0009] As a further optimization, one end of the blower B is fixedly connected to the air inlet pipe B, a heating pipe is installed inside the housing, and a wind vane is fixedly installed at the bottom of the housing.

[0010] As a further optimization, the monitoring mechanism includes a tension roller, the bottom of which is installed at the edge of the upper surface of the processing table, and multiple tension rollers are provided. Induction rings are embedded on both sides of the outer surface of the tension roller. One end of the tension roller is fixedly connected to a wire, and one end of the wire is electrically connected to a monitoring sensor.

[0011] As a further optimization, a groove is provided on one side of the top of the frame, and a through pipe is installed on the inner wall of the groove.

[0014] As a further optimization, a rotating roller is installed on the side wall of the frame, and a square groove is opened on one side of the upper surface of the processing table, with a rotating rod installed inside the square groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the flexible dot matrix positioning mechanism, the multi-layer non-woven fabric is bonded and positioned by negative pressure dot matrix adsorption. This can evenly fix the fabric surface and effectively prevent deviation, slippage, and misalignment when the multi-layer non-woven fabric is stacked. This ensures the alignment accuracy and thickness uniformity of the multi-layer filter material.

Through the set monitoring mechanism, the tension of the non-woven fabric is monitored in real time, and problems such as abnormal tension, deviation and wrinkles are captured in time. This ensures the stability of the feeding tension of the entire production line, and can provide real-time feedback on the operating status of the filter material. This reduces the stretching deformation and interlayer misalignment caused by tension fluctuations, ensures the uniformity of filter material size and processing consistency, reduces the defect rate, and realizes real-time monitoring of processing quality. 3. Through the set winding mechanism, the servo motor can control the winding speed and tension to achieve uniform and stable winding, avoiding filter material stretching deformation and uneven tension. The matching ventilation duct structure can ventilate and regulate the temperature of the winding roller and filter material, reduce the problem of finished filter material adhesion and wrinkles, and ensure the flatness of the roll material.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figures 1 to 7A multi-layer composite antibacterial nonwoven filter material integrated processing device includes a frame 1, a processing table 2 installed inside the frame 1, a flexible dot matrix positioning mechanism installed in the middle of the processing table 2, a vertical plate 3 installed at the tail end of the processing table 2, a winding mechanism installed on the outer surface of the vertical plate 3, a heating and drying mechanism installed on the top of the frame 1, and a monitoring mechanism installed at the edge of the upper surface of the processing table 2. The flexible dot matrix positioning mechanism includes a cover plate 4, which is installed on the outside of the processing table 2 in the middle. The surface of the cover plate 4 has several holes, and an air pipe 5 is inserted into the port of the hole. A filter 6 is installed inside the hole. An A transmission pipe 7 is fixedly connected to the outer surface of the air pipe 5. A vacuum adsorption pump 8 is installed at one end of the A transmission pipe 7. The outer surface of the vacuum adsorption pump 8 is installed at the bottom of the processing table 2. The filter 6 is made of breathable filter material to prevent non-woven fabric fibers, debris and impurities from entering the air pipe 5 and to prevent the A transmission pipe 7 from becoming blocked and the vacuum adsorption pump 8 from wearing out.

[0021] In one embodiment of the present invention, the winding mechanism includes a servo motor 9. The outer surface of the servo motor 9 is fixedly installed on the outer surface of the upright plate 3. The output end of the servo motor 9 is splinedly connected to a winding roller 10. An air duct 11 is embedded on the surface of the winding roller 10. A transmission pipe 12 is fixedly connected to the inside of the air duct 11 through a connecting pipe. One end of the transmission pipe 12 is fixedly connected to an A blower 13. One end of the blower 13 is fixedly connected to an A inlet pipe 14. The servo motor 9 achieves linear speed synchronization with the entire production line, controls the winding speed, and completes constant tension and uniform speed winding to avoid filter material stretching deformation, uneven tension, wrinkling and edge lifting. The blower 13 introduces airflow into the air duct 11 inside the winding roller 10 through the A inlet pipe 14 and the B transmission pipe 12 to ventilate, dehumidify and cool the wound filter material, reduce the problems of antibacterial filter material winding adhesion, residual heat deformation and moisture deterioration, ensure the flatness and structural stability of the roll material, and improve the quality of the finished roll material.

[0022] The warm drying mechanism includes a housing 15. An electric push rod 16 is installed in the middle of the upper surface of the housing 15. Connecting pipes 17 are fixedly connected to both sides of the upper surface of the housing 15. A C-transmission pipe 18 is fixedly connected to the outer surface of the connecting pipe 17. A B-blower 19 is fixedly connected to one end of the C-transmission pipe 18. The B-blower 19 provides circulating air, which, together with the heating structure inside the housing 15, forms a uniform hot air field to achieve low-temperature gradient drying and curing of antibacterial nonwoven fabric. This reduces the damage of high temperature to antibacterial components and nonwoven fabric substrate, and ensures the stable adhesion of the antibacterial layer.

[0023] One end of blower 19 is fixedly connected to air inlet pipe 20. Heating pipe 21 is installed inside housing 15. Air vane 22 is fixedly installed at the bottom of housing 15. Outside air enters blower 19 through air inlet pipe 20 and enters housing 15 cavity after being conveyed. Heating pipe 21 heats the airflow evenly. The hot air is then evenly diffused downwards through bottom air vane 22 to blow onto non-woven filter material, forming a gentle and uniform low-temperature hot air field. This achieves gradient drying and curing of antibacterial coating, avoiding local overheating damage to antibacterial components and non-woven substrate, ensuring stable curing and adhesion of antibacterial agent, and ensuring air permeability and overall structural stability of filter material.

[0024] The monitoring mechanism includes a tension roller 23. The bottom of the tension roller 23 is installed at the edge of the upper surface of the processing table 2. Multiple tension rollers 23 are set up. Sensing rings 24 are embedded on both sides of the outer surface of the tension roller 23. One end of the tension roller 23 is fixedly connected to a wire 25, and the other end of the wire 25 is electrically connected to a monitoring sensor 26. Multiple tension rollers 23, together with the double-sided sensing rings 24, can realize tension monitoring of the non-woven fabric throughout the entire process and in all directions, improve monitoring accuracy, and effectively avoid problems such as non-woven fabric stretching deformation, interlayer misalignment, and wrinkles caused by tension fluctuations.

[0025] A groove is provided on one side of the top of the frame 1, and a through pipe 27 is installed on the inner wall of the groove. Multiple sets of flow pipes 28 are installed inside the through pipe 27. A spray head 29 is fixedly installed at one end of the flow pipe 28. A valve 30 is installed at the junction of the through pipe 27 and the flow pipe 28. The multiple sets of flow pipes 28, together with the independent valve 30, can realize the precise and uniform administration of antibacterial liquid, adapting to the processing needs of filter materials of different specifications. The setting of ultrasonic atomizing spray head 29 improves the uniformity of antibacterial agent adhesion, reduces liquid waste, and at the same time ensures the bonding strength between the antibacterial coating and the non-woven fiber.

[0026] One end of the through pipe 27 is fixedly connected to the D transmission pipe 31, one end of the D transmission pipe 31 is fixedly connected to the pump 32, and one end of the pump 32 is fixedly connected to the feed pipe 33. The pump 32, together with the D transmission pipe 31 and the feed pipe 33, constitutes a complete drug delivery system. The high-precision metering pump can realize the quantitative and continuous delivery of the drug solution, avoiding drug waste. At the same time, the self-priming function can effectively eliminate air bubbles in the pipeline and ensure smooth drug administration.

[0027] A control sensor 34 is installed on the surface of the upright plate 3. The control sensor 34 is electrically connected to blower A 13. When the control sensor 34 detects that the temperature of the filter material on the surface of the take-up roller 10 is too high or the humidity is too high, it can immediately send a control signal to blower A 13 to adjust the air supply power and air supply temperature of blower A 13. The appropriate amount of airflow is delivered to the filter material through the air duct 11 inside the take-up roller 10 to realize real-time temperature and humidity control during the take-up process, so as to avoid problems such as adhesion, deformation and decreased antibacterial activity of the filter material due to abnormal temperature and humidity.

[0028] A rotating roller 35 is installed on the side wall of the frame 1. A square groove is opened on one side of the upper surface of the processing table 2, and a rotating rod 36 is installed inside the square groove. The rotating roller 35 and the rotating rod 36 work together to provide stable conveying power for the non-woven fabric, ensuring that the non-woven fabric passes through the antibacterial modification area at a uniform speed and avoiding jamming.

[0029] In application, the nonwoven fabric substrate is fed into the processing area of ​​the processing table 2 via the rotating roller 35 on the side wall of the frame 1 and the rotating rod 36 in the square groove of the processing table 2. Simultaneously, multiple tension rollers 23, along with the sensing ring 24, wire 25, and monitoring sensor 26, monitor the fabric tension in real time, achieving both tension monitoring and stable feeding. The vacuum adsorption pump 8 is activated, creating negative pressure adsorption through the holes in the A transmission pipe 7, air pipe 5, and cover plate 4. With the protection of the filter sheet 6 inside the holes, the multi-layer nonwoven fabric substrate is precisely adsorbed and positioned on the surface of the cover plate 4 in the middle of the processing table 2, completing the pre-fixation of the multi-layer filter material alignment and preventing misalignment. Subsequently, the pump 32 is activated, delivering antibacterial solution to the through pipe 27 through the feed pipe 33 and D transmission pipe 31. The valve 30 is adjusted to control... The flow rate is controlled, and the liquid medicine is sprayed onto the positioned non-woven fabric substrate by the spray head 29 through the flow pipe 28 to perform antibacterial liquid modification treatment. The blower B 19 is started, and air is sent into the housing 15 through the transmission pipe C 18 and the connecting pipe 17. With the help of the heating pipe 21 and the bottom air plate 22 in the housing 15, warm drying and curing are achieved. The electric push rod 16 can adjust the position of the housing 15 to achieve low temperature gradient drying and curing, and complete the fixation and shaping of the antibacterial agent. The servo motor 9 is started to drive the winding roller 10 to wind up the finished filter material. At the same time, the blower A 13 can be turned on to provide auxiliary ventilation adjustment to the winding roller 10 through the air inlet pipe A 14, the transmission pipe B 12 and the air pipe 11. The control sensor 34 on the upright plate 3 is linked to regulate the overall machine operating parameters to complete the winding process of the finished roll material.
