Description

Technical Field

[0001] This utility model relates to the field of antiviral nonwoven fabric production technology, specifically a uniform soaking device for pharmaceutical agents in the production of medical antiviral nonwoven fabric. Background Technology

[0002] Antiviral nonwoven fabrics acquire antiviral functions by soaking in specific agents. Their main functions include killing or inhibiting viruses, blocking transmission routes, and enhancing protective effects. The soaking agents (such as quaternary ammonium salts, silver ions, copper ions, chlorine dioxide, etc.) can destroy the viral envelope, protein coat, or genetic material (RNA / DNA), rendering the virus infective. Some agents can stably adhere to the nonwoven fabric fibers, slowly releasing active ingredients to achieve a continuous antiviral effect (such as the antiviral layer in medical masks).

[0003] The existing Chinese utility model patent with publication number CN222053394U discloses an soaking device for nonwoven fabric production, including a soaking tank. Each of the four corners of the top of the soaking tank has an inverted T-shaped groove. Slider blocks are fitted at the top and bottom of the groove's inner cavity. A connecting plate is positioned between two sliders on the same side, with both ends of the connecting plate fixedly connected to the two sliders. Several rollers are equidistantly arranged vertically on both sides between the two connecting plates. This utility model, an soaking device for nonwoven fabric production, winds the nonwoven fabric onto one take-up roller. One end of the nonwoven fabric passes sequentially through one extrusion roller, several layers of rollers, and another extrusion roller before being wound onto another take-up roller. This avoids stacking of the nonwoven fabric. During soaking and bleaching, two geared motors work cyclically, driving the nonwoven fabric back and forth for soaking and winding, enhancing the soaking effect.

[0004] The aforementioned soaking device for nonwoven fabric production removes excess liquid from the surface of the nonwoven fabric by using a squeeze roller. This method results in the nonwoven fabric not absorbing a sufficient amount of reagent. Furthermore, since the reagent needs to remain on the surface of the nonwoven fabric, the aforementioned soaking device rolls up the fabric before the reagent is completely dry. During the rolling process, the nonwoven fabric is subjected to pressure, causing some of the reagent to leach out, making it unsuitable for reagent soaking of nonwoven fabrics. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a uniform soaking device for the production of medical antiviral nonwoven fabrics, which solves the problem of drug precipitation due to pressure during winding and the inability of the nonwoven fabric to absorb sufficient drug.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a uniform soaking device for producing medical antiviral nonwoven fabric, comprising a base plate, a drying mechanism for drying the nonwoven fabric and a water control mechanism for removing excess agent installed above the base plate;

[0007] The drying mechanism includes a flat tube fixedly installed above the base plate, an electric heating plate fixedly installed inside the flat tube, a cylinder inserted through the rear side of the flat tube, a connecting rod fixedly installed at the lower end of the cylinder, a scraper movably installed below the connecting rod, and a torsion spring fixedly installed between the connecting rod and the scraper.

[0008] The water control mechanism includes an air compressor fixedly installed above the base plate. An exhaust pipe is fixedly installed at the exhaust end of the air compressor. A diverter pipe is fixedly installed at the top of the exhaust pipe. A guide pipe is fixedly installed below the diverter pipe. An intake pipe is fixedly installed at the air intake end of the air compressor.

[0009] Preferably, a reagent tank is fixedly installed above the base plate, the front end of the reagent tank is connected to the rear end of the flat tube, and a guide roller is fixedly installed inside the reagent tank. There are five guide rollers in total, which are respectively installed on the upper and lower sides of the rear end of the reagent tank, above the front end of the reagent tank, and at the front and rear ends of the flat tube. A connecting pipe is fixedly installed at the rear end of the reagent tank, and a liquid pump is fixedly installed at the rear end of the connecting pipe.

[0010] Preferably, the rear half of the flat tube has an inclined groove structure, the front half has a straight tubular structure, and the heating plate is fixedly installed on the bottom and top surfaces of the inner cavity of the flat tube.

[0011] Preferably, the cylinders are equidistantly installed above the rear sliding groove structure of the flat tube, the scraper and the connecting rod are rotatably connected, one end of the torsion spring is fixedly connected to the scraper, and the other end is fixedly connected to the connecting rod.

[0012] Preferably, the diameter of the diverter is smaller than that of the exhaust pipe, and six vertical branches are equidistantly arranged below the diverter, with the top end of the guide pipe connected to the branches of the diverter.

[0013] Preferably, the bottom end of the guide pipe is flat, and the two ends of the guide pipe are fixedly connected to the left and right sides of the rear sliding groove structure of the flat pipe, respectively. One end of the air inlet pipe is fixedly connected to the air inlet end of the air compressor, and the other end passes through the right side of the flat pipe and is located between the upper and lower heating plates inside the flat pipe.

[0014] Beneficial effects

[0015] This invention provides a device for uniformly soaking pharmaceutical agents in the production of medical antiviral nonwoven fabrics. Compared with the prior art, it has the following advantages:

[0016] (1) The uniform soaking device for the production of medical antiviral nonwoven fabric has a flat tube with a sloping groove structure in the rear half and a straight tubular structure in the front half. The electric heating plate is fixedly installed on the bottom and top surfaces of the inner cavity of the flat tube. The guide roller inside the flat tube can keep the nonwoven fabric in the area between the electric heating plates to prevent the nonwoven fabric from contacting the electric heating plates. The electric heating plate raises the temperature inside the tubular structure at the front end to dry the nonwoven fabric. When the air compressor is running, it can extract the high humidity air inside the flat tube through the air inlet pipe to prevent the air humidity inside the flat tube from being too high and affecting the drying efficiency. This method can dry the nonwoven fabric after soaking, thereby preventing the drug from being released due to the pressure between the nonwoven fabrics during the winding process.

[0017] (2) The uniform soaking device for the medicine in the production of medical antiviral nonwoven fabric, through the setting of the air compressor, the air compressor can deliver compressed air into the exhaust pipe, and the airflow is evenly distributed in the guide pipe through the diverter pipe at the top of the exhaust pipe. The guide pipe can restrict the airflow from being discharged from the bottom. Due to the restriction of the flat structure at the bottom of the guide pipe, the airflow will blow towards the nonwoven fabric. By adjusting the power of the air compressor, the airflow speed can be adjusted so that the airflow can blow away the excess medicine from the nonwoven fabric when it comes into contact with the nonwoven fabric. At the same time, the cylinder is located on the guide roller behind the flat pipe. Directly above, the distance between the connecting rod and the guide roller is adjusted by the cylinder, causing the scraper to rotate forward and contact the non-woven fabric above the guide roller. The torsion spring between the scraper and the connecting rod generates elasticity when the scraper rotates, thus pressing the scraper onto the non-woven fabric. The elasticity of the torsion spring is adjusted by adjusting the height of the connecting rod, thereby controlling the pressure applied to the non-woven fabric by the scraper and the guide roller below. This removes excess agent while preventing excessive pressure that would prevent the non-woven fabric from absorbing enough agent, thus facilitating subsequent drying operations on the non-woven fabric.

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a uniform soaking device for producing medical antiviral nonwoven fabric, including a base plate 1, a drug pool 11 fixedly installed on the top of the base plate 1, the front end of the drug pool 11 being connected to the rear end of a flat tube 21, a guide roller 12 fixedly installed inside the drug pool 11, five guide rollers 12 being respectively installed on the upper and lower sides of the rear end of the drug pool 11, above the front end of the drug pool 11, and at the front and rear ends of the flat tube 21, a connecting pipe 13 fixedly installed at the rear end of the drug pool 11, and a liquid pump 14 fixedly installed at the rear end of the connecting pipe 13.

[0025] Specifically, the base plate 1 supports the reagent pool 11 and the flat tube 21, and restricts the relative position between the reagent pool 11 and the flat tube 21. The reagent pool 11 can hold a certain amount of reagent. The guide roller 12 restricts the non-woven fabric to move vertically downward at the rear end of the reagent pool 11 so that the non-woven fabric can enter below the reagent liquid surface. The guide roller 12 on the front side of the reagent pool 11 restricts the height of the non-woven fabric when it is discharged from the reagent pool 11. It cooperates with the guide roller 12 at the rear end of the flat tube 21 to make the non-woven fabric parallel to the chute structure above the chute structure on the rear side of the flat tube 21. The guide roller 12 inside the flat tube 21 can keep the non-woven fabric in the area between the heating plates 22 to prevent the non-woven fabric from contacting the heating plates 22. The liquid pump 14 is connected to the reagent pool 11 through the connecting pipe 13 so that the liquid pump 14 can replenish the reagent into the reagent pool 11.

[0026] A drying mechanism 2 for drying non-woven fabric is installed above the base plate 1. The drying mechanism 2 includes a flat tube 21 fixedly installed above the base plate 1. An electric heating plate 22 is fixedly installed inside the flat tube 21. A cylinder 23 is inserted through the rear side of the flat tube 21. A connecting rod 24 is fixedly installed at the lower end of the cylinder 23. A scraper 25 is movably installed below the connecting rod 24. A torsion spring 26 is fixedly installed between the connecting rod 24 and the scraper 25. The rear half of the flat tube 21 is a sloping groove structure, and the front half is a straight tubular structure. The electric heating plate 22 is fixedly installed on the bottom and top surfaces of the inner cavity of the flat tube 21. The cylinder 23 is equidistantly installed above the rear groove structure of the flat tube 21. The scraper 25 and the connecting rod 24 are rotatably connected. One end of the torsion spring 26 is fixedly connected to the scraper 25, and the other end is fixedly connected to the connecting rod 24.

[0027] Specifically, the grooving structure at the rear end of the flat tube 21 facilitates the return of the agent to the agent pool 11, while the flat structure at the front end reduces heat loss. The heating plate 22 raises the internal temperature of the tubular structure at the front end, drying the nonwoven fabric. The cylinder 23 is located directly above the guide roller 12 at the rear of the flat tube 21. The distance between the connecting rod 24 and the guide roller 12 is adjusted by the cylinder 23, causing the scraper 25 to rotate forward and contact the nonwoven fabric above the guide roller 12. Since the torsion spring 26 between the scraper 25 and the connecting rod 24 generates elasticity when the scraper 25 rotates, it presses the scraper 25 onto the nonwoven fabric. The elasticity of the torsion spring 26 is adjusted by adjusting the height of the connecting rod 24, thereby controlling the pressure applied to the nonwoven fabric by the scraper 25 and the guide roller 12 below. This removes excess agent while preventing excessive pressure that would prevent the nonwoven fabric from absorbing sufficient agent.

[0028] A water control mechanism 3 for removing excess chemicals is installed above the base plate 1. The water control mechanism 3 includes an air compressor 31 fixedly installed above the base plate 1. An exhaust pipe 32 is fixedly installed at the exhaust end of the air compressor 31. A diverter pipe 33 is fixedly installed at the top of the exhaust pipe 32. A guide pipe 34 is fixedly installed below the diverter pipe 33. An intake pipe 35 is fixedly installed at the intake end of the air compressor 31. The diameter of the diverter pipe 33 is smaller than that of the exhaust pipe 32. Six vertical branches are equidistantly arranged below the diverter pipe 33. The top of the guide pipe 34 is connected to a branch of the diverter pipe 33. The bottom end of the guide pipe 34 is flat. Both ends of the guide pipe 34 are fixedly connected to the left and right sides of the rear sliding groove structure of the flat pipe 21, respectively. One end of the intake pipe 35 is fixedly connected to the intake end of the air compressor 31. The other end passes through the right side of the flat pipe 21 and is located between the upper and lower heating plates 22 inside the flat pipe 21.

[0029] Specifically, the air compressor 31 can deliver compressed air into the exhaust pipe 32. The airflow is evenly distributed inside the guide pipe 34 through the diverter pipe 33 at the top of the exhaust pipe 32. The guide pipe 34 can restrict the airflow from being discharged from the bottom. Due to the restriction of the flat structure at the bottom of the guide pipe 34, the airflow will blow towards the non-woven fabric. The airflow speed can be adjusted by adjusting the power of the air compressor 31 so that the airflow can blow away excess agent from the non-woven fabric when it comes into contact with it. At the same time, since one end of the air inlet pipe 35 is fixedly connected to the air inlet end of the air compressor 31, and the other end passes through the right vertical side of the flat pipe 21 and is located between the upper and lower heating plates 22 inside the flat pipe 21, the air compressor 31 can extract the high humidity air inside the flat pipe 21 through the air inlet pipe 35 during operation, preventing the air humidity inside the flat pipe 21 from being too high and affecting the drying efficiency. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0030] During operation, the rear half of the flat tube 21 has a sloping groove structure, while the front half has a straight tubular structure. Heating plates 22 are fixedly installed on the bottom and top surfaces of the inner cavity of the flat tube 21. Guide rollers 12 inside the flat tube 21 keep the nonwoven fabric within the area between the heating plates 22, preventing contact between the nonwoven fabric and the heating plates 22. The heating plates 22 raise the temperature inside the tubular structure at the front end, drying the nonwoven fabric. During operation, the air compressor 31 extracts the high-humidity air from inside the flat tube 21 through the air inlet pipe 35, preventing excessive humidity from affecting drying efficiency. This method dries the nonwoven fabric after soaking, preventing chemical precipitation due to pressure between the nonwoven fabric particles during winding. The air compressor 31 delivers compressed air into the exhaust pipe 32, and the airflow is evenly distributed inside the guide pipe 34 through the diverter pipe 33 at the top of the exhaust pipe 32. The airflow is restricted from exiting from the bottom. Due to the flat structure at the bottom of the guide pipe 34, the airflow will be blown towards the non-woven fabric. The airflow speed is adjusted by adjusting the power of the air compressor 31 so that the airflow can blow away excess agent from the non-woven fabric when it comes into contact with it. At the same time, the cylinder 23 is located directly above the guide roller 12 behind the flat pipe 21. The distance between the connecting rod 24 and the guide roller 12 is adjusted by the cylinder 23 so that the scraper 25 rotates forward and comes into contact with the non-woven fabric above the guide roller 12. Since the torsion spring 26 between the scraper 25 and the connecting rod 24 will generate elasticity when the scraper 25 rotates, the scraper 25 is pressed on the non-woven fabric. The elasticity of the torsion spring 26 is adjusted by adjusting the height of the connecting rod 24, thereby controlling the pressure applied to the non-woven fabric by the scraper 25 and the lower guide roller 12. This removes excess agent while preventing excessive pressure that would prevent the non-woven fabric from absorbing enough agent, so as to facilitate the subsequent drying operation of the non-woven fabric.
