Description

Technical Field

[0001] This invention relates to the field of non-woven fabric processing technology for face masks, specifically a double-sided disinfection and sterilization machine for non-woven fabric face masks. Background Technology

[0002] Masks are hygiene products worn over the mouth and nose to filter the air entering the mouth and nose. In the production of non-woven masks, sterilization machines are usually used to sterilize the non-woven fabric.

[0003] For example, a non-woven fabric disinfection and drying device for mask processing, disclosed in CN216898238U, includes a disinfection chamber, a drying chamber integrally formed on one side of the disinfection chamber, and a stirring mechanism inside the disinfection chamber. The stirring mechanism includes a first motor installed on the lower surface of the disinfection chamber, with stirring blades installed at the output end of the first motor, a second motor installed on one side of the disinfection chamber, a rotating shaft installed at the output end of the second motor, and three cams arranged in a linear array installed on the outer side of the rotating shaft.

[0004] The existing technology has the following technical defects: When disinfecting non-woven fabrics, the surface of the non-woven fabrics inevitably contains lint and fluff. After the non-woven fabrics pass through the disinfection box, the loose fibers on the surface of the disinfectant solution will float randomly. After disinfection, the disorderly distribution of the loose fibers will increase the difficulty for staff to clean the loose fibers inside the disinfectant box. At the same time, when the non-woven fabrics are dried after disinfection, the contact time between the non-woven fabrics and the hot air is short, which may cause the non-woven fabrics to be transported out before they are completely dried.

[0005] Therefore, we proposed a double-sided disinfection and sterilization machine for non-woven fabric masks to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a double-sided disinfection and sterilization machine for non-woven fabric masks, in order to solve the problem mentioned in the background art that existing disinfection devices on the market inevitably have lint and fluff on the surface of non-woven fabrics during disinfection. When the non-woven fabric passes through the disinfection chamber, the loose lint on the surface of the non-woven fabric will float haphazardly on the surface of the disinfectant solution. After disinfection, the disorderly distribution of the loose lint makes it difficult for workers to clean the loose lint inside the disinfectant tank. At the same time, when the non-woven fabric is dried after disinfection, the contact time between the non-woven fabric and the hot air is short, which easily leads to the non-woven fabric being transported out before it is completely dried.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a double-sided disinfection and sterilization machine for non-woven fabric masks, comprising a machine body, a cabinet door, a guide roller, non-woven fabric, a lower guide roller, an upper guide roller, a squeeze roller, a built-in spring, and a liquid storage tank. The machine body is fitted with a hinged cabinet door on its side, and a guide roller is installed on the right side of the machine body. The non-woven fabric passes through the guide roller, the lower guide roller, the upper guide roller, and the squeeze roller in sequence and extends out of the machine body to connect with a winding device. The lower guide roller is located inside the liquid storage tank, which is filled with disinfectant and fixed to the lower end of the machine body. The middle part of the squeeze roller is connected to the inside of the machine body by a built-in spring.

[0008] Also includes:

[0009] An overlapping block is fixed in the middle of the inner side of the liquid storage tank. The overlapping block is located directly below the extrusion roller. An assisting airbag is installed on the inner side of the overlapping block. A water suction pipe is installed on the lower side of the assisting airbag, and a guide pipe is installed on the upper side of the assisting airbag. A one-way valve is installed on both the guide pipe and the water suction pipe.

[0010] A pressure rod is installed on the lower side of the power-assisted airbag. The pressure rod is connected to each other by a sleeve spring and a connecting block. A deflector wheel is installed on the outer side of the pressure rod and the deflector wheel is fixed on the lower guide roller.

[0011] A drive gear is fixed on the upper guide roller. A movable frame is installed on the outside of the drive gear, and a positioning plate is fixedly installed on the upper end of the movable frame. A central insertion rod is fixedly connected to the upper end of the positioning plate, and a push roller is connected to the central insertion rod by a bearing. A guide mechanism to accelerate the drying speed of the nonwoven fabric is installed inside the push roller.

[0012] An exhaust hood is fixed to the inner side of the machine body. The exhaust hood is connected to a hot air blower via a drain pipe, and the hot air blower is fixed to the side of the machine body.

[0013] Preferably, the side of the airbag and the end of the pressure rod that extends into the overlapping block are fitted together, and the pressure rod forms an elastic telescopic structure through a sleeve spring and the overlapping block.

[0014] By adopting the above technical solution, the airbag can be squeezed by moving the pressure rod.

[0015] Preferably, the upper end of the overlapping block is configured as an arc-shaped structure, and the end of the extrusion roller at the upper end of the overlapping block can slide inside the machine body.

[0016] By adopting the above technical solution, the disinfectant inside the nonwoven fabric can be easily squeezed out through the arc-shaped structure at the top of the extrusion roller and the overlapping block.

[0017] Preferably, the ends of the blades on the side of the actuating wheel and the ends of the pressure rod are both set as spherical structures, and four blades are evenly distributed at equal angles on the side of the actuating wheel.

[0018] By adopting the above technical solution, the pressure rod can reciprocate by the contact and disengagement between the side blades and the end of the pressure rod after the actuating wheel rotates.

[0019] Preferably, the drive gear is configured as a half-gear structure, and the drive gear and the inner side of the movable frame are meshed, allowing the movable frame to slide on the machine body.

[0020] By adopting the above technical solution, the rotation of the drive gear enables the movable frame to move back and forth left and right using the half-tooth structure.

[0021] Preferably, the central insert rod and the push roller are distributed on the left and right sides of the nonwoven fabric, and the surface of the push roller is in contact with the edge of the nonwoven fabric.

[0022] By adopting the above technical solution, the movement of the push roller enables the nonwoven fabric to move in a wave-like motion, thereby increasing the residence time of the nonwoven fabric inside the machine body.

[0023] Preferably, the guiding mechanism consists of a striking rod, a return spring, and a magnetic block. The striking rod is installed inside the push roller, and the striking rod is connected to the inner wall of the push roller through the return spring. Magnetic blocks are installed at the lower end of the striking rod and on the side of the central insert rod.

[0024] Preferably, the end of the striking rod away from the central insert rod is in contact with the inner wall of the push roller, and the striking rod forms an elastic telescopic structure with the push roller through a reset spring.

[0025] By adopting the above technical solution, the reset spring can be used to reset and rebound the push roller after it has moved.

[0026] Preferably, the magnetic blocks at the lower end of the striking rod and the magnetic blocks on the side of the central insert rod have opposite magnetic properties, and the magnetic blocks are evenly distributed around the central insert rod.

[0027] By adopting the above technical solution, the striking rod can be reciprocated by the approach and distance of the magnetic block at the end of the striking rod and the circumferential magnetic block of the central insertion rod.

[0028] Compared with the prior art, the beneficial effects of the present invention are: the non-woven fabric double-sided disinfection and sterilization machine for masks can easily concentrate the floating hair on the surface of the disinfectant during the disinfection and sterilization process, which is convenient for subsequent cleaning of the floating hair on the surface of the disinfectant. At the same time, it can increase the contact time between hot air and non-woven fabric, and improve the drying effect of non-woven fabric after disinfection and sterilization.

[0029] 1. Equipped with an assisting airbag, the lower guide roller rotates during the non-woven fabric conveying and winding process. After the lower guide roller rotates, the contact and disengagement between the end of its upper actuating wheel and the pressure rod causes the pressure rod to reciprocate. The reciprocating movement of the pressure rod compresses the assisting airbag. When the assisting airbag is compressed, the disinfectant inside is discharged downwards into the storage tank through the guide pipe. The disinfectant enters the storage tank and creates layers of waves on the water surface, which can shake the lint floating on the surface of the storage tank to the side of the storage tank to accumulate, preventing the lint from being distributed randomly on the surface of the storage tank and reducing the difficulty of subsequent lint removal and cleaning.

[0030] 2. Equipped with a push roller, when the upper guide roller rotates during the nonwoven fabric transmission process, the drive gear can drive the movable frame belt and positioning plate to move the central insert rod and push roller back and forth. The compression of the nonwoven fabric by the push roller after it moves can make the nonwoven fabric be conveyed outward in a meandering shape, thereby increasing the residence time of the nonwoven fabric inside the machine.

[0031] 3. Equipped with a tapping bar, when the push roller squeezes the nonwoven fabric, the friction between the push roller and the nonwoven fabric increases. At this time, the nonwoven fabric can cause the push roller to rotate during the conveying process. After the push roller rotates, the magnetic block at the end of the tapping bar and the magnetic block on the side of the center insert rod move closer and further away, which can cause the tapping bar to move back and forth. The tapping bar can knock the push roller to generate vibration. Since the fabric is stretched and in a taut state, the vibration of the push roller can eject some of the water mist attached to the nonwoven fabric, thereby improving the drying speed of the nonwoven fabric.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figure 1-8 The present invention provides the following two embodiments:

[0043] Example 1:

[0044] In existing disinfection devices, the surface of non-woven fabrics inevitably contains lint and fluff when disinfecting them. After passing through the disinfection chamber, these loose fibers disperse haphazardly onto the surface of the disinfectant solution. This uneven distribution of fibers after disinfection increases the difficulty of cleaning the inside of the disinfectant tank. To address this technical problem, this implementation discloses the following technical details: Figure 1-4 As shown,

[0045] A double-sided disinfection and sterilization machine for non-woven fabric masks includes a machine body 1, a cabinet door 2, a guide roller 3, non-woven fabric 4, a lower guide roller 5, an upper guide roller 6, a squeeze roller 7, an internal spring 25, and a liquid storage tank 26. The cabinet door 2 is hinged to the side of the machine body 1, and the guide roller 3 is installed on the right side of the machine body 1. The non-woven fabric 4 passes sequentially through the guide roller 3, the lower guide roller 5, the upper guide roller 6, and the squeeze roller 7, and then extends out of the machine body 1 to connect with a winding device. The lower guide roller 5 is located inside the liquid storage tank 26, which is filled with disinfectant and fixed to the lower end of the machine body 1. The middle part of the squeeze roller 7 is connected to the interior of the machine body 1 via the internal spring 25. The inner side of the liquid storage tank 26... A connecting block 8 is fixed in the middle, located directly below the extrusion roller 7. An assisting airbag 9 is installed inside the connecting block 8. A suction pipe 10 is installed on the lower side of the assisting airbag 9, and a guide pipe 11 is installed on the upper side of the assisting airbag 9. Both the guide pipe 11 and the suction pipe 10 are equipped with one-way valves 12. A pressure rod 13 is installed on the lower side of the assisting airbag 9. The pressure rod 13 is connected to the connecting block 8 via a sleeve spring 14, and a deflector wheel 15 is installed on the outer side of the pressure rod 13. The deflector wheel 15 is fixed to the lower guide roller 5. The side of the assisting airbag 9 and the end of the pressure rod 13 that extends into the connecting block 8 are in close contact with each other, and the pressure rod 13 forms an elastic telescopic structure with the connecting spring 14 and the connecting block 8. The upper end of the connecting block 8 is designed with an arc shape, and the end of the extrusion roller 7 at the upper end of the connecting block 8 can slide inside the machine body 1. The ends of the blades on the side of the actuating wheel 15 and the ends of the pressure rod 13 are both set as spherical structures, and four blades are evenly distributed at equal angles on the side of the actuating wheel 15.

[0046] The working principle of this embodiment is as follows: When it is necessary to disinfect the non-woven fabric 4, the cabinet door 2 is opened and the disinfectant is injected into the storage tank 26. At this time, the winding equipment is turned on to transport and wind up the non-woven fabric 4. During the winding process, the non-woven fabric 4 passes through the disinfectant in the storage tank 26, and the disinfectant is used to disinfect the non-woven fabric 4 on both sides. Then, the non-woven fabric 4 passes through the upper end of the overlap block 8 and is squeezed out by the extrusion roller 7. Then, during the outward transport process, the non-woven fabric 4 passes through the hot air blown outward by the hot air blown outward by the hot air blower 24 using the diversion pipe 23 and the air hood 22, thereby drying the disinfected non-woven fabric 4. However, during the transport and winding process of the non-woven fabric 4, the lower guide roller 5 and the upper guide roller 6 can rotate synchronously. When the lower guide roller 5 rotates, it can drive the actuating wheel 15 on it to rotate. When the actuating wheel 15 rotates, its end contacts the pressure rod 13, thereby pressing the pressure rod. The lever 13 is squeezed, causing it to move towards the inside of the overlapping block 8. After moving, the lever 13 can squeeze the assist airbag 9, causing the disinfectant inside the assist airbag 9 to be discharged downward through the guide pipe 11 into the storage tank 26. When the actuating wheel 15 rotates and its end moves away from the end of the lever 13, the lever 13 is reset under the action of the sleeve spring 14. After being reset, the lever 13 stops squeezing the assist airbag 9. After being reset, the assist airbag 9 draws the disinfectant from the storage tank 26 through the suction pipe 10. This process is repeated. When the assist airbag 9 discharges the internal disinfectant downward through the guide pipe 11 into the storage tank 26, the waves stirred up on the water surface by the disinfectant entering the storage tank 26 can concentrate and shake the messy fluff floating on the water surface to the side of the storage tank 26, which facilitates the subsequent unified collection and cleaning of the messy fluff on the water surface of the storage tank 26.

[0047] Example 2:

[0048] The double-sided disinfection and sterilization machine for non-woven fabric masks disclosed in this embodiment is a further improvement based on the above-mentioned Embodiment 1. When the non-woven fabric is dried after disinfection, the contact time between the non-woven fabric and the hot air is relatively short, which easily leads to the non-woven fabric being conveyed out before it is completely dried, thereby reducing the overall drying effect of the non-woven fabric after disinfection. To solve this technical problem, this embodiment discloses the following technical contents, such as... Figure 2 and Figure 5-8 As shown;

[0049] A drive gear 16 is fixed to the upper guide roller 6. A movable frame 17 is mounted on the outside of the drive gear 16, and a positioning plate 18 is fixedly mounted on the upper end of the movable frame 17. A central insertion rod 19 is fixedly connected to the upper end of the positioning plate 18, and a push roller 20 is connected to the central insertion rod 19 by a bearing. A guide mechanism 21 for accelerating the drying speed of the nonwoven fabric is installed inside the push roller 20. An air vent 22 is fixed to the inner side of the machine body 1. The air vent 22 is connected to a hot air blower 24 through a drain pipe 23, and the hot air blower 24 is fixed to the side of the machine body 1. The drive gear 16 is configured as a half-gear structure, and the drive gear 16 and the inner side of the movable frame 17 are meshed, allowing the movable frame 17 to slide on the machine body 1. The central insertion rod 19 and the push roller 20 are distributed on the left and right sides of the nonwoven fabric 4, and the surface of the push roller 20 is in contact with the edge of the nonwoven fabric 4. The guiding mechanism 21 consists of a striking rod 211, a return spring 212, and magnetic blocks 213. The striking rod 211 is installed inside the push roller 20 and is connected to the inner wall of the push roller 20 via the return spring 212. Magnetic blocks 213 are installed at the lower end of the striking rod 211 and on the side of the central insertion rod 19. The end of the striking rod 211 away from the central insertion rod 19 is in contact with the inner wall of the push roller 20, and the striking rod 211 and the push roller 20 form an elastic telescopic structure via the return spring 212. The magnetic blocks 213 at the lower end of the striking rod 211 and the magnetic blocks 213 on the side of the central insertion rod 19 have opposite magnetic properties, and the magnetic blocks 213 are evenly distributed circumferentially around the central insertion rod 19.

[0050] The working principle of this embodiment is as follows: When the nonwoven fabric 4 is being conveyed and wound, its upper guide roller 6 rotates. The rotation of the upper guide roller 6 drives the drive gear 16 to rotate. Through the half-tooth structure of the drive gear 16, the movable frame 17 drives the positioning plate 18 to move back and forth. When the positioning plate 18 moves, the central insert rod 19 fixedly connected to its upper end drives the push rollers 20 on the left and right sides of the nonwoven fabric 4 to move relative to each other. When the push rollers 20 move relative to each other and come into contact with the nonwoven fabric 4, the nonwoven fabric 4 can be conveyed and wound outward in a meandering shape. By using the meandering conveying of the nonwoven fabric 4, the time for the nonwoven fabric 4 to be dried by hot air inside the machine body 1 can be increased. At the same time, because the push rollers 20 move and come into contact with the nonwoven fabric 4, the nonwoven fabric 4 is tightened, and the friction between the push rollers 20 and the nonwoven fabric 4 is reduced. As the force increases, the nonwoven fabric 4 can cause the push roller 20 to rotate synchronously during the transmission process. When the push roller 20 rotates, the magnetic block 213 at its end and the magnetic block 213 on the side of the central insertion rod 19 approach each other, thereby using magnetic attraction to move the beating rod 211 toward the side of the central insertion rod 19. When the push roller 20 rotates, the magnetic block 213 at the end of the beating rod 211 and the magnetic block 213 on the side of the central insertion rod 19 move away from each other, and the beating rod 211 returns to its original position under the action of the return spring 212. After returning, the beating rod 211 collides with the push roller 20 and generates vibration. Since the nonwoven fabric 4 is in a taut state at this time, when the vibration generated by the push roller 20 acts on the nonwoven fabric 4, it can eject some of the water mist on the nonwoven fabric 4 outward, thereby increasing the drying speed of the nonwoven fabric 4.

[0051] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
