Description

Technical Field

[0001] This invention belongs to the field of non-woven fabric sterilization, specifically a sterilization device for non-woven fabric used in surgical gowns. Background Technology

[0002] Surgical gowns are made of medical shielding fabric, which primarily focuses on barrier properties, including the ability to prevent the penetration of liquids and microorganisms. During medical care, medical personnel inevitably come into contact with the patient's blood and bodily fluids, which may carry various pathogens such as HBV, HCV, and HIV. Surgical gowns thus provide protection for medical personnel. Surgical gowns are generally made of non-woven fabric, and the non-woven fabric needs to be sterilized using steam sterilization during the production of surgical gowns.

[0003] When non-woven fabrics are sterilized with steam, the air layer between the fibers in the dry state hinders steam penetration, affecting the sterilization effect on the inside of the non-woven fabric. In order to reduce volume, sterilized non-woven fabrics are mostly rolled into tubes and placed in the sterilization box. The rolled-up non-woven fabric easily forms a sealed air layer inside, and the steam can only sterilize the surface of the non-woven fabric, making it difficult to quickly penetrate into the interior. This results in a long sterilization time for the non-woven fabric, affecting the sterilization efficiency. Moreover, prolonged sterilization of the surface of the non-woven fabric can easily lead to damage to the fiber structure and a decrease in strength. Secondly, because the density of steam is low, it will continue to float upward after being released. This means that only the bottom of the non-woven fabric can be sterilized, while the top of the non-woven fabric has poor contact with the steam, resulting in uneven sterilization. In addition, the non-woven fabric absorbs a lot of moisture after sterilization, which not only greatly reduces the water capacity in the steam sterilization box, requiring frequent water replenishment, but also makes the non-woven fabric that is too damp or even dripping difficult to dry, and it is more likely to breed bacteria inside.

[0004] Therefore, the present invention provides a sterilization and disinfection device for non-woven fabric used in surgical gowns. Summary of the Invention

[0005] To address the shortcomings of existing technologies and solve the problem of air layers between fibers hindering steam penetration during steam sterilization of non-woven fabrics in a dry state, thus affecting the sterilization effect on the interior of the fabric, and to reduce volume, sterilized non-woven fabrics are often rolled into tubes before being placed in the sterilization chamber. These rolled-up non-woven fabrics tend to form a sealed air layer inside, allowing steam to only sterilize the surface layer and failing to quickly penetrate the interior. This results in a long sterilization time, reducing sterilization efficiency, and prolonged sterilization of the surface layer can easily damage the fiber structure. The problems include reduced strength, and the fact that, due to the low density of steam, it floats upwards after being released, thus only sterilizing the bottom of the nonwoven fabric. The top of the nonwoven fabric has poor contact with the steam, resulting in uneven sterilization. In addition, the sterilized nonwoven fabric absorbs a lot of moisture, which not only significantly reduces the water capacity in the steam sterilization chamber, requiring frequent water replenishment, but also makes it difficult to dry excessively damp or even dripping nonwoven fabric, which is more prone to bacterial growth. This invention proposes a sterilization device for nonwoven fabric used in surgical gowns.

A third spring is fixedly connected to the top of the top block, and the top of the third spring is fixedly connected to the extrusion block.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The present invention discloses a sterilization device for non-woven fabric used in surgical gowns. A hydraulic cylinder controls a support plate to move downward, thereby immersing the tubular non-woven fabric in water inside the chamber. The water wets the tubular non-woven fabric, improving the effect of steam penetration. Through the cooperation of a second cam and a first spring, the tubular non-woven fabric immersed in water continuously vibrates downward, preventing the outer layer of the tubular non-woven fabric from forming a membrane and air bubbles after contact with water, which would affect water penetration.

[0021] 2. The sterilization device for nonwoven fabric used in surgical gowns of the present invention uses a first cam and a second spring to move a pressing plate back and forth, squeezing the tubular nonwoven fabric on the support plate into an elliptical shape. The two fourth springs and the clamping plate then restore the deformed tubular nonwoven fabric to its original shape. This process is repeated, and the kneading and squeezing of the tubular nonwoven fabric breaks down the air layer inside, allowing steam to penetrate quickly. The kneading and squeezing also unfolds the folds inside the tubular nonwoven fabric, avoiding sterilization blind spots.

[0022] 3. The sterilization device for nonwoven fabric used in surgical gowns of the present invention uses a fifth spring to press a locking block against one side of a tubular nonwoven fabric. When the extrusion plate moves upward, the locking block extends outward during the upward movement under the action of the fifth spring. At this time, the straight surface of the top of the locking block pushes one side of the tubular nonwoven fabric, and the top block presses the other side of the tubular nonwoven fabric, causing the tubular nonwoven fabric to rotate counterclockwise. This process is repeated. As the extrusion plate moves up and down, the tubular nonwoven fabric continues to rotate counterclockwise. Thus, as the steam rises, the position of the tubular nonwoven fabric in contact with the steam is adjusted, so that the tubular nonwoven fabric can be sterilized evenly.

[0023] 4. The sterilization and disinfection device for nonwoven fabric used in surgical gowns of the present invention uses a hydraulic cylinder to continuously control the support seat to move upward, so that the support plate continues to approach the extrusion plate. Under the extrusion of the support plate and the extrusion plate, the tubular nonwoven fabric in the middle is flattened, and the steam water condensed on the tubular nonwoven fabric is squeezed out. The squeezed steam water falls down along the drain trough and re-enters the chamber, which avoids the water in the chamber being consumed too quickly and effectively treats the excess water in the tubular nonwoven fabric, thereby improving the subsequent drying effect of the tubular nonwoven fabric.

[0024] 5. The sterilization device for nonwoven fabric used in surgical gowns described in this invention uses the arc surface at the bottom of the cover plate to wrap around the steam. The rotating fan blades create a downward vortex for the steam, causing the rising steam to flow downwards and sterilize the tubular nonwoven fabric below again. By setting the top of the inner wall of the cover plate as an arc surface, water droplets condensed on the arc surface flow to both sides along the arc surface, preventing water droplets from dripping directly downwards onto the tubular nonwoven fabric, which would cause the tubular nonwoven fabric to cool down and affect the sterilization effect.

[0037] 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.

[0038] like Figures 1 to 10 As shown, the present invention provides a technical solution: a sterilization and disinfection device for nonwoven fabric used in surgical gowns, comprising a housing 1, a steam generator 4 disposed at the bottom of the inner wall of the housing 1, two side plates 2 symmetrically fixedly connected to the top of the housing 1, a cover plate 3 slidably connected between the two side plates 2, and a stop block 42 fixedly connected to the outer wall of the side plates 2 and below the cover plate 3; further comprising: a support assembly for placing tubular nonwoven fabric; a vibration assembly for controlling the vibration of the tubular nonwoven fabric; and a compression assembly for compressing the tubular nonwoven fabric on the support assembly. Non-woven fabric; the support assembly includes two fixing plates 5, which are respectively fixedly installed on the outer walls of two side plates 2. A hydraulic cylinder 6 is fixedly connected to the inner wall of the fixing plate 5. A support base 7 is fixedly connected to the output end of the hydraulic cylinder 6. A slide plate 8 is slidably connected to the inner wall of the support base 7. Several first sliding shafts 9 are fixedly connected at equal intervals to the top of the slide plate 8. The top of the first sliding shafts 9 passes through the support base 7 and is fixedly connected to the support plate 11. The support plate 11 is arc-shaped. Several drainage grooves 12 are equidistantly opened on the inner wall of the support plate 11.

[0039] Through the above technical solution, steam and water are filled into the box 1, the cover plate 3 is lifted upwards, and the tubular non-woven fabric is placed on the support plate 11. Then the cover plate 3 is released and falls downwards to seal the top of the box 1. The cover plate 3 is supported by the stop block 42. The hydraulic cylinder 6 is activated, which drives the support seat 7 to move downwards, causing the slide plate 8 to move downwards, which in turn drives the first slide shaft 9 to move downwards, causing the support plate 11 to move downwards. This allows the tubular non-woven fabric to be immersed in the water in the box 1, so that the water wets the tubular non-woven fabric and improves the effect of steam penetration. After the tubular non-woven fabric is wetted, the hydraulic cylinder 6 controls the tubular non-woven fabric to move upwards, so that the tubular non-woven fabric is lifted off the water surface. At this time, the steam generator 4 heats the water in the box 1 and generates steam that floats upwards to disinfect and sterilize the tubular non-woven fabric on the support plate 11. The drainage groove 12 facilitates the steam to pass upwards through the support plate 11.

[0040] Specifically, the vibration assembly includes a first motor 34, which is fixedly installed on the outer wall of the housing 1. The output end of the first motor 34 extends into the interior of the housing 1 and is fixedly connected to a second rotating shaft 35. A second cam 36 is fixedly connected to the outer wall of the second rotating shaft 35. A through groove 33 is provided at the bottom of the support base 7. A first spring 10 is sleeved on the outer wall of the first sliding shaft 9.

[0041] Through the above technical solution, when the support seat 7 moves downward and approaches the second cam 36, the first motor 34 is started, driving the second rotating shaft 35 to rotate, causing the second cam 36 to rotate. When the protruding end of the second cam 36 rotates to the top, it enters the support seat 7 along the through groove 33 and presses against the bottom of the slide plate 8. Under the pressure of the second cam 36, the slide plate 8 moves upward, driving the first sliding shaft 9 to move upward, causing the support plate 11 to move upward, and driving the tubular nonwoven fabric to move upward. While the slide plate 8 moves upward, it presses the first spring 10. When the protruding end of the second cam 36 rotates to the bottom, under the action of the first spring 10, the slide plate 8 moves downward, driving the support plate 11 to move downward and vibrate, causing the tubular nonwoven fabric to move downward and vibrate. This process is repeated, and when the tubular nonwoven fabric is submerged in water, it is continuously vibrated downward, preventing the outer layer of the tubular nonwoven fabric from forming a membrane and air bubbles after contact with water, which would affect water penetration.

[0042] Specifically, the extrusion assembly includes an extrusion plate 16, which is disposed between two side plates 2 and above a fixed plate 5. A second sliding shaft 13 is fixedly connected to the top of the fixed plate 5, and the second sliding shaft 13 is slidably connected to the extrusion plate 16. A limit block 15 is fixedly connected to the top of the second sliding shaft 13. A second spring 14 is sleeved on the outer wall of the second sliding shaft 13. The bottom of the second spring 14 is fixedly connected to the fixed plate 5, and the top of the second spring 14 is fixedly connected to the extrusion plate 16. Two fixed brackets 30 are symmetrically fixedly connected between the two side plates 2. A first rotating shaft 31 is rotatably connected between the two fixed brackets 30. The first rotating shaft 31 is located above the extrusion plate 16, and a first cam 32 is fixedly connected to the outer wall of the first rotating shaft 31. One end of the first rotating shaft 31 passes through the fixed bracket 30 and is fixedly connected to a second cam 32. Synchronous pulley 38, one end of the second rotating shaft 35 passes through the housing 1 and is fixedly connected to the first synchronous pulley 37. The first synchronous pulley 37 and the second synchronous pulley 38 are connected by a synchronous belt 39. A reset unit is provided at the bottom of the extrusion plate 16 and above each support plate 11. The reset unit includes two third sliding shafts 21. The two third sliding shafts 21 are symmetrically fixedly installed at the bottom of the extrusion plate 16 with the support plate 11 as the center. The outer walls of the two third sliding shafts 21 are slidably connected to sliders 23. The outer walls of the two third sliding shafts 21 are fitted with fourth springs 22. One end of the fourth spring 22 is fixedly connected to the slider 23, and the other end of the fourth spring 22 is fixedly connected to the extrusion plate 16. The bottom of the two sliders 23 is fixedly connected to clamping plates 24, and the inner wall of the clamping plates 24 is fixedly connected to arc-shaped plates 25.

[0043] Through the above technical solution, after the tubular nonwoven fabric is wetted, the hydraulic cylinder 6 controls the support seat 7 to move upward, causing the tubular nonwoven fabric to move between the two clamping plates 24. The two clamping plates 24 clamp the two sides of the tubular nonwoven fabric. The second rotating shaft 35 rotates, driving the first synchronous wheel 37 to rotate. Through the set synchronous belt 39, the second synchronous wheel 38 rotates, causing the first rotating shaft 31 to rotate, driving the first cam 32 to rotate. When the protruding end of the first cam 32 rotates downward, it pushes the extrusion plate 16 to move downward, squeezing the tubular nonwoven fabric on the support plate 11, squeezing the tubular nonwoven fabric into an elliptical shape. The downward movement of the extrusion plate 16 drives the two clamping plates 24 to move downward. After the tubular nonwoven fabric is shaped into an elliptical shape, it pushes the two clamping plates 24 away from each other, causing the two sliders 23 to move away from each other, pressing the two fourth springs 22. As the first cam 32 moves downward, it presses the second spring 14. When the protruding end of the first cam 32 rotates upward, the second spring 14 causes the extrusion plate 16 to move upward. After the extrusion plate 16 is no longer pressed, the two clamping plates 24 move closer to each other under the action of the two fourth springs 22, pressing the deformed tubular nonwoven fabric and restoring it to its original shape. This process is repeated. As the first cam 32 rotates, the two clamping plates 24 continuously knead the tubular nonwoven fabric. By kneading and squeezing the tubular nonwoven fabric, the air layer inside the tubular nonwoven fabric can be broken, allowing steam to quickly penetrate inward. Kneading and squeezing can also unfold the folds inside the tubular nonwoven fabric, avoiding sterilization blind spots. By setting an arc plate 25 inside the clamping plate 24, the contact between the clamping plate 24 and the tubular nonwoven fabric can be reduced, allowing steam to better penetrate the tubular nonwoven fabric.

[0044] Specifically, the inner wall of the slider 23 on the right side is equidistantly connected with several locking blocks 29. The bottom of the locking blocks 29 is set as an inclined surface. One end of the locking blocks 29 is fixedly connected with a fifth spring 28. One end of the fifth spring 28 is fixedly connected to the slider 23. The outer wall of the slider 23 on the left side is equidistantly connected with several pulleys 27. The inner wall of the extrusion plate 16 and above the support plate 11 is provided with a slot 17. The inner wall of the slot 17 is equidistantly fixedly connected with several extrusion blocks 18. The extrusion blocks 18 are set as arcs. The bottom of the extrusion block 18 and near the left side is slidably connected with a top block 20. The top of the top block 20 is fixedly connected with a third spring 19. The top of the third spring 19 is fixedly connected to the extrusion block 18.

[0045] Through the above technical solution, when the extrusion plate 16 moves downward to extrude the tubular nonwoven fabric, it drives several extrusion blocks 18 to press against the top of the tubular nonwoven fabric. After the tubular nonwoven fabric deforms, it presses against the inclined surface at the bottom of the clamping block 29, causing the clamping block 29 to move and press the fifth spring 28. At the same time, under the extrusion of the tubular nonwoven fabric, the top block 20 moves upward and presses the third spring 19. When the extrusion plate 16 moves upward, it loses its extrusion effect. The two clamping plates 24 move upward and move closer to each other. Under the action of the fifth spring 28, the clamping block 29 extends outward during the upward movement. At this time, the straight surface at the top of the clamping block 29 pushes one side of the tubular nonwoven fabric, and cooperates with the top block 20 to press the other side of the tubular nonwoven fabric, pushing the tubular nonwoven fabric to rotate counterclockwise. Through the set pulley 27, the pressure between the tubular nonwoven fabric and the other clamping plate is reduced. The friction of plate 24 facilitates the counterclockwise rotation of the tubular nonwoven fabric. This reciprocating motion, along with the up-and-down movement of the extrusion plate 16, causes the tubular nonwoven fabric to rotate continuously counterclockwise. This adjusts the position of the tubular nonwoven fabric in contact with the steam as it rises, ensuring uniform sterilization. After sterilization, the hydraulic cylinder 6 continues to control the support base 7 to move upwards, causing the support plate 11 to continuously approach the extrusion plate 16. Under the pressure of the support plate 11 and the extrusion plate 16, the tubular nonwoven fabric in the middle is flattened, squeezing out the condensed steam water. The squeezed steam water falls along the drain trough 12 and re-enters the chamber 1, preventing excessive water consumption in the chamber 1 and effectively treating excess water within the tubular nonwoven fabric, thus improving the subsequent drying effect.

[0046] Specifically, the bottom of each of the two clamping plates 24 is fixedly connected to a guide plate 26, which is arc-shaped and installed at an angle.

[0047] The above technical solution guides the upward-floating steam through the arc surface at the bottom of the guide plate 26, allowing the steam to flow to the tubular nonwoven fabric.

[0048] Specifically, the top of the inner wall of the cover plate 3 is set as an arc surface, and a second motor 40 is fixedly connected to the top of the cover plate 3. The output end of the second motor 40 extends into the interior of the cover plate 3 and is fixedly connected to a fan blade 41.

[0049] Through the above technical solution, after the steam sterilizes the tubular non-woven fabric, it continues to float upwards and is enveloped by the arc surface at the bottom of the cover plate 3. The second motor 40 is started, which drives the fan blade 41 to rotate, so that the steam forms a downward vortex. This causes the rising steam to flow downwards and sterilize the tubular non-woven fabric below again. The set empty groove 17, together with several extrusion blocks 18, facilitates the contact between the downward flowing steam and the tubular non-woven fabric. By setting the top of the inner wall of the cover plate 3 as an arc surface, the water droplets condensed on the arc surface flow to both sides along the arc surface, avoiding the water droplets from dripping directly downwards onto the tubular non-woven fabric, which would cause the tubular non-woven fabric to cool down and affect the sterilization effect.

[0050] In use, steam and water are filled into the housing 1. The cover plate 3 is lifted upwards, and the tubular nonwoven fabric is placed on the support plate 11. Then, the cover plate 3 is released, and it falls downwards to seal the top of the housing 1. The cover plate 3 is supported by the stop block 42. The hydraulic cylinder 6 is activated, which moves the support base 7 downwards, causing the slide plate 8 to move downwards, which in turn moves the first sliding shaft 9 downwards, causing the support plate 11 to move downwards. This allows the tubular nonwoven fabric to be soaked in the water inside the housing 1, wetting the fabric and improving the steam penetration effect. When the support base 7 moves downwards and approaches the second cam 36, the first motor 34 is activated, which drives the second rotating shaft 35 to rotate, causing the second cam 36 to rotate. When the protruding end of the second cam 36 rotates to the top, it enters the support along the through groove 33. Inside seat 7, and pressed against the bottom of slide plate 8, under the pressure of second cam 36, slide plate 8 moves upward, driving first slide shaft 9 to move upward, causing support plate 11 to move upward, and driving tubular nonwoven fabric to move upward. Simultaneously, slide plate 8 presses against first spring 10. When the protruding end of second cam 36 rotates downward, under the action of first spring 10, slide plate 8 moves downward, driving support plate 11 to move downward and vibrate, causing tubular nonwoven fabric to move downward and vibrate. This process repeats, controlling the tubular nonwoven fabric to continuously vibrate downward while immersed in water, preventing the outer layer of the tubular nonwoven fabric from forming a membrane and air bubbles after contact with water, thus affecting water penetration. After the tubular nonwoven fabric is wetted, hydraulic cylinder 6 controls the tubular nonwoven fabric to move upward... The upward movement moves the tubular nonwoven fabric between the two clamping plates 24, which hold the fabric on both sides. Meanwhile, the steam generator 4 heats the water in the housing 1, generating steam that floats upwards to disinfect the tubular nonwoven fabric on the support plate 11. The drainage groove 12 facilitates the upward flow of steam through the support plate 11, and the arc surface at the bottom of the guide plate 26 guides the upward-floating steam towards the tubular nonwoven fabric. Simultaneously, the rotation of the second rotating shaft 35 drives the first synchronous wheel 37 to rotate. The synchronous belt 39 drives the second synchronous wheel 38 to rotate, causing the first rotating shaft 31 to rotate, which in turn drives the first cam 32 to rotate. When the protruding end of the first cam 32 rotates downwards, it pushes the extrusion plate 16 towards... The downward movement of the compression plate 16 compresses the tubular nonwoven fabric on the support plate 11, shaping it into an ellipse. The downward movement of the compression plate 16 causes the two clamping plates 24 to move downwards. After the tubular nonwoven fabric is elliptical, it pushes the two clamping plates 24 away from each other, causing the two sliders 23 to move away from each other and pressing the two fourth springs 22. Simultaneously, the downward movement of the compression plate 16 presses the second spring 14. When the protruding end of the first cam 32 rotates to the top, the compression plate 16 moves upwards under the action of the second spring 14. After the compression of the compression plate 16 is removed, the two clamping plates 24 move closer together under the action of the two fourth springs 22, compressing the deformed tubular nonwoven fabric and restoring it to its original shape. This process repeats as the first cam 32 rotates.The two clamping plates 24 continuously knead the tubular nonwoven fabric. This kneading and squeezing breaks down the air layer inside the fabric, allowing steam to penetrate quickly. The kneading and squeezing also unfolds the folds within the fabric, preventing sterilization blind spots. An arc-shaped plate 25 inside the clamping plates 24 reduces contact between the plates and the fabric, further enhancing steam penetration. When the extrusion plate 16 moves downwards to press the fabric, it causes several extrusion blocks 18 to press against the top of the fabric. After deformation, the fabric presses against the inclined surface at the bottom of the clamping block 29, causing the clamping block 29 to... The fifth spring 28 is pressed down, and under the pressure of the tubular nonwoven fabric, the top block 20 moves upward, pressing the third spring 19. When the pressure plate 16 moves upward, it loses its pressing effect, and the two clamping plates 24 move upward and move closer to each other. Under the action of the fifth spring 28, the locking block 29 extends outward during the upward movement. At this time, the straight surface of the top of the locking block 29 pushes one side of the tubular nonwoven fabric, and cooperates with the top block 20 to press the other side of the tubular nonwoven fabric, pushing the tubular nonwoven fabric to rotate counterclockwise. This process is repeated. As the pressure plate 16 moves up and down back and forth, it drives the tubular nonwoven fabric to rotate continuously counterclockwise, thus causing the steam to... As the steam rises, the position of the tubular nonwoven fabric in contact with the steam is adjusted to ensure uniform sterilization. After sterilizing the tubular nonwoven fabric, the steam continues to float upwards, enveloping the steam through the arc surface at the bottom of the cover plate 3. The second motor 40 is activated, driving the fan blades 41 to rotate, creating a downward-flowing vortex. This causes the rising steam to flow downwards again, sterilizing the tubular nonwoven fabric below. The provided slots 17, along with several extrusion blocks 18, facilitate contact between the downward-flowing steam and the tubular nonwoven fabric. By setting the top of the inner wall of the cover plate 3 as an arc surface, water droplets condensed on the arc surface radiate to both sides along the arc surface. To prevent water droplets from dripping directly onto the tubular nonwoven fabric and causing it to cool down, thus affecting the sterilization effect, after the tubular nonwoven fabric is sterilized, the hydraulic cylinder 6 continues to control the support base 7 to move upward, so that the support plate 11 continues to approach the extrusion plate 16. Under the pressure of the support plate 11 and the extrusion plate 16, the tubular nonwoven fabric in the middle is flattened, squeezing out the condensed steam water on the tubular nonwoven fabric. The squeezed steam water falls down along the drain trough 12 and re-enters the chamber 1, preventing the water in the chamber 1 from being consumed too quickly and effectively treating excess water in the tubular nonwoven fabric, thus improving the subsequent drying effect of the tubular nonwoven fabric.
