Description

Technical Field

[0001] The present invention relates to the technical field of sterilization and disinfection devices, and more specifically, to a sterilization and disinfection device for non-woven fabric production. Background Art

[0002] During the production process of non-woven fabrics, due to the high hygienic requirements for the production environment, sterilization and disinfection devices can usually ensure that non-woven fabrics remain clean during production and reduce the contamination of bacteria or other harmful substances. The main sterilization and disinfection links include surface sterilization. Among them, ultraviolet disinfection is the most common in surface sterilization, which can effectively kill microorganisms such as bacteria and viruses on the surface of non-woven fabrics. Heat treatment sterilization includes hot air disinfection. By heating the air to a certain temperature and blowing it onto the surface of non-woven fabrics, it can effectively kill germs, bacteria, and viruses on the surface of non-woven fabrics. Compared with ultraviolet and ozone, hot air disinfection has stronger penetrability and can treat the entire surface of non-woven fabrics.

[0003] A Chinese patent with the publication number CN118436830B discloses an automatic sterilization device for textile fabrics, including a device main body, which can wash away the impurities and chemical pigments carried during the fabric production process, improving the sterilization effect of disinfectants; and reducing the contact between impurities in the fabric and disinfectants, which can reduce the impurities in the disinfectants, thereby improving the convenience during the fabric sterilization process and enhancing the sterilization efficiency of the sterilization device; moreover, after the fabric is disinfected with disinfectants, through multiple washes, the residue of the fabric disinfectant is reduced, improving the treatment effect of fabric disinfection and sterilization.

[0004] A Chinese patent with the publication number CN109411698A discloses a spunlace non-woven fabric automatic sterilization device, including a sterilization chamber, which uses a sterilization chamber containing an ultraviolet area, a steam area, and a spraying area to perform multiple disinfection and sterilization treatments on non-woven fabrics with different sterilization principles, so as to achieve the effect of fully and efficiently sterilizing non-woven fabrics.

[0005] In the above-mentioned and similar prior arts, hot air and ultraviolet rays are usually used to sterilize and disinfect non-woven fabrics. Although these two methods can achieve the sterilization and disinfection effect of non-woven fabrics to a certain extent, when using hot air for disinfection, the hot air will be evenly distributed in the disinfection chamber. However, due to its low penetrability, the hot air is difficult to effectively penetrate into the internal layers of non-woven fabrics, resulting in the inability to fully disinfect the deep parts of non-woven fabrics, greatly reducing the disinfection effect. Especially when dealing with multi-layered or thicker non-woven fabrics, the disinfection efficiency is even lower. Secondly, during ultraviolet disinfection, the dispersion degree of ultraviolet lamps is relatively high, and the light source cannot be concentrated enough, thereby reducing the sterilization efficiency of ultraviolet lamps and the utilization rate of ultraviolet rays, and further affecting the sterilization and disinfection effect.

[0006] Therefore, the present invention provides a sterilization and disinfection device for non-woven fabric production, which can enable hot air to fully penetrate non-woven fabrics of different widths and make full use of ultraviolet light for disinfection. Summary of the Invention

Detailed implementation mode

[0021] In order to make the technical means, technical features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0022] Embodiment: As Figures 1-9 shown, a sterilization and disinfection device for non-woven fabric production according to the present invention includes a disinfection box 1. A non-woven fabric body 4 is placed through the inside of the disinfection box 1. A control box is fixedly installed on one side of the disinfection box 1. A plurality of ventilation openings 2 are formed through one side of the disinfection box 1. A filter screen 3 is fixedly installed inside the ventilation openings 2. One end of the opening of the air duct 6 communicates with the ventilation openings 2. A plurality of synchronous motors 5 are fixedly installed on one side of the disinfection box 1 through a mounting seat. The plurality of synchronous motors 5 can work synchronously.

[0023] Specifically, the disinfection box 1 can provide a through space for the ventilation openings 2. The ventilation openings 2 can allow the outside air to enter the inside of the air duct 6. The ventilation holes can provide a placement space for the filter screen 3. The filter screen 3 can filter the outside air to reduce the entry of impurities. The disinfection box 1 can provide a stable support for the control box and the synchronous motors 5. The control box is electrically connected to the plurality of synchronous motors 5, so that the control box can control the plurality of synchronous motors 5 to work or close simultaneously. The rotation speeds of the synchronous motors 5 are the same, so that the plurality of first bidirectional lead screws 231 can run synchronously.

[0024] In this embodiment, a plurality of air ducts 6 are fixedly installed on one inner wall of the disinfection box 1. A blowing hole 10 is formed through the side of the air duct 6 close to the non-woven fabric body 4. The plurality of air ducts 6 are located at the endpoints of the W shape. Two sliding grooves 11 are formed in the inner wall of the blowing hole 10. A blowing frame 12 is fixedly installed on one side of the air duct 6, and the blowing frame 12 is aligned with the position of the blowing hole 10. The side of the blowing frame 12 away from the air duct 6 contacts the non-woven fabric body 4. A heating grid 9 is fixedly installed inside the air duct 6. A fan 8 is rotatably installed inside the heating grid 9 through a bearing. One end of the fan 8 is rotatably installed on one inner wall of the air duct 6 through a bearing, and the other end of the fan 8 is fixedly installed with a blower 7. Two control knobs 14 are installed through the air duct 6 through bearings. One control knob 14 can control the heating effect of the heating grid 9, and the other control knob 14 can control the rotation speed of the blower 7. An activity groove 13 is formed on the side of the air duct 6 close to the blowing hole 10. The control knob 14 is located at the position of the activity groove 13. A worm gear 15 is fixedly installed at the end of the control knob 14 away from the air duct 6.

[0025] Specifically, the disinfection box 1 can provide stable support for the air duct 6. The air duct 6 can provide a space for the blowing hole 10 to be formed through. The blowing hole 10 can provide a ventilation channel for the air in the air duct 6. The blowing hole 10 can provide a space for the sliding groove 11 to be formed. The sliding groove 11 can provide a storage space and a sliding space for the sealing plate 233. The air duct 6 can provide stable support for the blowing frame 12. The blowing frame 12 can provide a guiding function for the air in the air duct 6, guiding the hot air to blow towards the non-woven fabric body 4. The heating grid 9 can heat the air to the required temperature, so that the heating grid 9 heats the outside air into hot air that can sterilize and disinfect. The fan 8 can evenly blow the hot air in the air duct 6 towards the blowing hole 10. The two control knobs 14 are electrically connected to the heating grid 9 and the blower fan 7 respectively. By rotating the control knob 14, the heating function of the heating grid 9 and the rotation speed of the blower fan 7 can be adjusted. The activity groove 13 can provide an activity space for the control knob 14. When the blowing area of the blowing frame 12 gradually decreases under the action of the sealing plate 233, increasing the heating power of the heating wire and the rotation speed of the blower 7 can keep the heat and wind speed blown out by the blowing frame 12 unchanged, so that the degree of hot air passing through the non-woven fabric body 4 is the same, and the heating, sterilization and disinfection effect on the non-woven fabric body 4 is the same.

[0026] In this embodiment, multiple groups of support plates 16 are fixedly installed on one side of the air duct 6 close to the blowing holes 10. Each group has two support plates 16. A support roller 17 is rotatably installed inside the two support plates 16 of each group through bearings. The position of the support roller 17 farthest from the air duct 6 is parallel to the side of the blowing frame 12 away from the air duct 6. A guiding groove 18 is penetrated and opened on the side of the support plate 16 away from the air duct 6. A guiding plate 19 is slidably installed inside the guiding groove 18. One ends of the two guiding plates 19 on one side away from the air duct 6 are fixedly installed with a synchronous plate 20. An extrusion roller 21 is rotatably installed inside the synchronous plate 20 through bearings. The two extrusion rollers 21 close to each other and the two ends of the support roller 17 are elastically connected through springs 22 respectively. The springs 22 are located on the side of the support plate 16 away from the blowing frame 12. The non-woven fabric body 4 is located between the extrusion roller 21 and the support roller 17.

[0027] Specifically, the air duct 6 can provide stable support for the support plate 16. The support plate 16 can provide rotational support for the support roller 17. The support roller 17 can change the movement direction of the non-woven fabric body 4, so that the non-woven fabric body 4 can be parallel to one side of the blowing frame 12, enabling the hot air to blow directly against the non-woven fabric body 4. The support plate 16 can provide a space for opening the guiding groove 18. The guiding groove 18 can provide a moving space for the guiding plate 19. The guiding plate 19 can provide stable support for the synchronous plate 20. The synchronous plate 20 can drive the two extrusion rollers 21 to move synchronously. The spring 22 can provide a pressure for the extrusion roller 21 to extrude the non-woven fabric body 4. The spring 22 extrudes the non-woven fabric body 4 towards the air duct 6 through the extrusion roller 21. When the hot air blows vertically against the non-woven fabric body 4, the extrusion roller 21 can reduce the displacement of the non-woven fabric body 4 caused by the wind force, so that the non-woven fabric body 4 can seal the blowing frame 12, reducing the hot air from blowing out from the gap between the non-woven fabric body 4 and the blowing frame 12.

[0028] In this embodiment, a wind limiting component 23 is arranged inside the blowing holes 10. The wind limiting component 23 includes a sealing plate 233. The wind limiting component 23 is assembled to adjust the positions of the two sealing plates 233 according to non-woven fabric bodies 4 of different widths to control the size of the blowing holes 10. The wind limiting component 23 includes a plurality of bidirectional lead screws 231. The bidirectional lead screws 231 are rotatably installed inside the disinfection box 1 through bearings. One end of the bidirectional lead screw 231 is fixedly connected to the output end of the synchronous motor 5. The bidirectional lead screw 231 penetrates through the inside of the blowing frame 12 through bearings. Two limiting plates 232 are threadedly installed on the outer side of the bidirectional lead screw 231. The limiting plates 232 are located inside the blowing frame 12. The limiting plates 232 are in contact with both sides of the non-woven fabric body 4. The two sealing plates 233 are respectively fixedly installed on the sides of the two limiting plates 232 away from each other. The two sealing plates 233 are respectively located inside the sliding grooves 11. Two spiral rings 234 are fixedly installed on the outer side of the bidirectional lead screw 231. The two spiral rings 234 are respectively engaged with the two worm wheels 15.

[0029] Specifically, the sealing plate 233 can slide along the inner side of the sliding groove 11, so that the sealing plate 233 can cooperate with the non-woven fabric body 4 to seal the blowing frame 12, and the blowing frame 12 can provide rotational support for the bidirectional screw rod 231, and the synchronous motor 5 can provide synchronous rotation driving force for multiple bidirectional screw rods 231, and the bidirectional screw rod can provide a threaded effect for the limit plate 232, and the limit plate 232 can provide movable support for the sealing plate 233, and the limit plate 232 can adjust the position according to the width of the non-woven fabric body 4, so that the blowing area of the blowing frame 12 can adapt to the width of the non-woven fabric body 4, and the bidirectional screw rod can provide a stable support for the worm ring 234, and the worm ring 234 can provide an engagement effect for the worm gear 15, and the control knob 14 can provide a stable support for the worm gear 15, so that when the bidirectional screw rod drives the worm ring 234 to rotate, the worm ring 234 can use the engagement effect with the worm gear 15 to drive the control knob 14 to rotate, thereby adjusting the heating power of the heating wire and the rotation speed of the fan 7.

[0030] In this embodiment, a plurality of ultraviolet lamps 25 are provided on the inner side of the disinfection box 1, and a limited light component 26 is provided around the ultraviolet lamp 25. The light limiting component 26 includes two side panels 261; the light limiting component 26 is assembled to adjust the position of the two side panels 261 according to the non-woven fabric body 4 of different widths to limit the light of the ultraviolet lamp 25. A plurality of groups of baffles 24 are fixedly installed on the inner side of the disinfection box 1, each group has two baffles 24, and the widths of the two baffles 24 of each group are different. The two ends of the ultraviolet lamp 25 are respectively close to the side of the two baffles 24 of each group. Fixedly connected, the two side panels 261 are respectively slidably installed on the outside of the baffle 24, and the side panels 261 and the side of the baffle 24 close to the ultraviolet lamp 25 are both paved with reflectors. A threaded ring 262 is fixedly installed on the side of the side panel 261 close to the shorter baffle 24, and a bidirectional screw rod 2 263 is threadedly installed on the inner side of the threaded ring 262, and the two ends of the bidirectional screw rod 2 263 are respectively rotatably installed on both sides of the disinfection box 1 through bearings, and the bidirectional screw rod 2 263 and the bidirectional screw rod 1 231 are connected through a sprocket transmission group 264, and the sprocket transmission group 264 is located on one side of the disinfection box 1.

[0031] Specifically, the ultraviolet lamp 25 can emit disinfection ultraviolet rays. The disinfection box 1 can provide stable support for the baffle 24. The baffle 24 can provide stable support for the ultraviolet lamp 25. The side plate 261 can provide stable support for the threaded ring 262, reflecting the ultraviolet rays irradiated on the surfaces of the baffle 24 and the side plate 261 to the surface of the non-woven fabric. The threaded ring 262 can engage in a threaded interaction with the bidirectional lead screw. When the bidirectional lead screw two 263 rotates, the bidirectional lead screw two 263 drives the side plate 261 to move by means of the threaded interaction with the threaded ring 262. The baffle 24 can provide a limiting effect on the movement of the side plate 261. The sprocket drive group 264 consists of a chain and two sprockets. The two sprockets are respectively fixed on the outer sides of the bidirectional lead screw one 231 and the bidirectional lead screw two 263, and the bidirectional lead screw one 231 and the bidirectional lead screw two 263 are synchronously driven and rotated through the sprocket drive group 264.

[0032] Working principle: When the staff disinfects the non-woven fabric body 4, first pass the non-woven fabric body 4 through the inside of the disinfection device. Subsequently, the staff controls multiple synchronous motors 5 to start simultaneously through the control box, so that when the synchronous motors 5 start, they drive the bidirectional lead screw one 231 to rotate. The bidirectional lead screw one 231 drives two limit plates 232 to move by means of the threaded action, so that the two limit plates 232 move to the positions in contact with both sides of the non-woven fabric body 4. The limit plates 232 drive the sealing plate 233 to move along the inner side of the sliding groove 11. At this time, the non-woven fabric body 4 and the sealing plate 233 cooperate to seal the air blowing frame 12. Subsequently, start the fan 7 and the heating wire to work. The fan 7 blows the outside air into the inside of the air duct 6. When the air passes through the heating grid 9, the heating grid 9 heats the air into hot air. After the hot air enters the inside of the air duct 6, it is blown towards the air blowing holes 10 under the action of the fan 8. The hot air passes through the air blowing holes 10 and the air blowing frame 12 and blows towards the non-woven fabric body 4. Since the non-woven fabric body 4 seals the air blowing frame 12, the hot air will pass through the inside of the non-woven fabric body 4 when it is blown out. At the same time, the hot air blows the non-woven fabric body 4, so that the non-woven fabric body 4 is subjected to a force away from the air duct 6. The non-woven fabric body 4 undergoes a small displacement under the elastic support of the pressing roller 21, so that most of the hot air passes through the non-woven fabric body 4 inside the air blowing frame 12 in a forced manner. The hot air penetrates deep into the inside of the non-woven fabric body 4, and can continuously and thoroughly disinfect non-woven fabric bodies 4 of different widths without dead angles, so as to improve the sterilization and disinfection degree of the non-woven fabric body 4. The W-shaped air duct 6 design enables the hot air to intermittently penetrate and sterilize both sides of the non-woven fabric body 4; When the first bidirectional lead screw 231 rotates, the bidirectional lead screw drives two worm rings 234 to rotate, enabling the worm rings 234 to drive the control of the rotation of two knobs through the meshing action with the worm wheel 15. When the bidirectional lead screw drives the two limit plates 232 to move towards each other, the blowing area of the blowing frame 12 gradually decreases under the action of the sealing plate 233. At this time, one control knob 14 controls the reduction of the heating power of the heating wire, and the other control knob 14 controls the reduction of the rotation speed of the blower 7, so that the heat and wind speed blown out by the blowing frame 12 remain unchanged. On the contrary, when the blowing area of the blowing frame 12 gradually increases, the heating power of the heating wire increases, and the rotation speed of the blower 7 increases. Thus, when hot air disinfection is performed on non-woven fabric bodies 4 of different widths, the degree to which the hot air passes through the non-woven fabric body 4 is the same, and the heating and sterilization and disinfection effects on the non-woven fabric body 4 are the same; When the first bidirectional lead screw 231 rotates, the first bidirectional lead screw 231 drives the second bidirectional lead screw 263 to rotate through the transmission of the sprocket transmission group 264, enabling the second bidirectional lead screw 263 to drive two side plates 261 to approach or move away from each other by means of the thread action with the thread ring 262, so that the side plates 261 adapt to the width of the non-woven fabric body 4. At this time, the ultraviolet lamp 25 in the sealed space formed by the side plates 261 and the baffle 24 emits ultraviolet light, causing the ultraviolet light to be reflected in the sealed space, so that the ultraviolet light can be concentrated to sterilize and disinfect the non-woven fabric body 4, not only improving the sterilization and disinfection effect of the ultraviolet lamp 25, but also improving the utilization efficiency of the ultraviolet light.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
