Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric production technology, specifically to a UV disinfection device for finished flocked spunlace nonwoven fabric. Background Technology

[0002] Flocked spunlace nonwoven fabric utilizes the physical property of like charges repelling and unlike charges attracting. The flocked fibers are given a negative charge, and then the spunlace nonwoven fabric to be flocked is placed under zero potential or grounded conditions. The fibers, attracted by the opposite potential, are attracted to the spunlace nonwoven fabric and rise vertically to its surface. Because the surface of the spunlace nonwoven fabric is coated with adhesive, the fibers are vertically adhered to the fabric. Flocked spunlace nonwoven fabric has been widely used in industries such as furniture, handicrafts, and bags.

[0003] Publication No. CN221266728U discloses a UV disinfection device for spunlace nonwoven fabric. The disinfection lamp irradiates both sides of the spunlace nonwoven fabric, effectively killing microorganisms on the product. Furthermore, the reflective element increases the effective light intensity and the UV lamp's irradiation range, thus effectively preventing excessive microbial levels on the fabric surface. It is easy to use. However, this patent still has the following problems in practical application:

[0004] While the UV disinfection device for spunlace nonwoven fabric can disinfect the fabric by irradiating both sides with a disinfection lamp, it lacks a dedicated cleaning mechanism to clean the surface of the UV lamps. Regular cleaning of the lamp surface is necessary to remove dust and dirt. Excessive dirt can impede UV penetration, affecting the disinfection effect. Furthermore, existing manual cleaning requires protective eyewear and long-sleeved clothing to avoid direct skin and eye exposure to UV rays, and the UV lamps must be turned off to prevent electric shock. This hinders continuous cleaning of the spunlace nonwoven fabric. Additionally, flocked spunlace nonwoven fabrics experience some shedding of fibers, requiring cleaning to prevent these fibers from adhering to the UV lamp surface and affecting the disinfection effect.

[0005] Therefore, a UV disinfection device for finished flocked spunlace nonwoven fabric is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a UV disinfection device for finished flocked spunlace nonwoven fabrics, addressing the problems of manual cleaning in the prior art. This requires wearing protective eyewear and long-sleeved clothing to avoid direct exposure of the skin and eyes to UV light, and also necessitates turning off the UV lamps to avoid the risk of electric shock during cleaning. Furthermore, it hinders continuous cleaning of the spunlace nonwoven fabric. Additionally, flocked spunlace nonwoven fabrics often experience some shedding of fibers on their surface, requiring the removal of these fibers during disinfection to prevent them from adhering to the UV lamp surface and affecting the disinfection effect.

[0020] Preferably, an adjusting motor is fixedly installed inside one side of the second sprocket limiting cover. The output end of the adjusting motor is fixedly connected to a second sprocket transmission assembly. Adjusting rotating rods are symmetrically installed on one side of the second sprocket transmission assembly. Bevel gear transmission assemblies are symmetrically installed on the outer sides of the two adjusting rotating rods. Adjusting bidirectional threaded rods are fixedly installed on the top of each of the four bevel gear transmission assemblies.

A drying air duct is rotatably connected to one side of the third sprocket transmission assembly. The dryer body is fixedly installed on the top of the drying air duct.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This ultraviolet disinfection device for flocked spunlace nonwoven fabric utilizes a rubber comb to clean and collect loose or unadheded fibers from the surface of the flocked spunlace nonwoven fabric. Simultaneously, the first and second cleaning rollers rotate in opposite directions, and the back of the rubber comb combs further smooths the fibers on the surface of the flocked spunlace nonwoven fabric, preventing frizz and ensuring the finished product's quality and aesthetics. The spiral characteristics of the cleaning spiral blades create a spiral flow that collects the cleaned fibers for subsequent cleaning. The bottom and top ultraviolet disinfection lamps disinfect both sides of the flocked spunlace nonwoven fabric, improving the disinfection effect. Furthermore, a lifting cylinder lowers the lifting plate and the protective cover, covering the disinfection area and enhancing the safety of the ultraviolet disinfection process. The specific details are as follows:

[0022] 1. By setting up a cleaning and disinfection mechanism, a moving cleaning solution can be placed inside the cleaning tank. The flocked spunlace nonwoven fabric body is wrapped around the outside of the first limiting roller, the first cleaning roller, and the second cleaning roller. By starting the cleaning motor, the first cleaning roller and the first meshing gear are driven to rotate. Utilizing the meshing connection between the first and second meshing gears, the second meshing gear drives the second cleaning roller to rotate. Because the first and second cleaning rollers rotate in opposite directions, the top and bottom sides of the flocked spunlace nonwoven fabric body can be cleaned. Through the elastic force of the tension spring, the tension sliding rod can drive the cleaning spiral blade and the rubber scraper to adhere to the surface of the flocked spunlace nonwoven fabric body. The rubber scraper can clean and collect the loose or unadheded flocking fibers on one side of the rubber scraper. At the same time, the first and second cleaning rollers rotate in opposite directions. The back of the rubber scraper can comb the fluff on the surface of the flocked spunlace nonwoven fabric, preventing the fluff from becoming frizzy, which would affect the finished quality and appearance of the flocked spunlace nonwoven fabric. At the same time, the spiral characteristics of the cleaning spiral blades can make the water flow spiral and collect the cleaned fluff for subsequent cleaning. By cleaning the fluff on the surface of the flocked spunlace nonwoven fabric in advance, it is possible to prevent the fluff from adhering to the surfaces of the bottom and top ultraviolet disinfection lamps, which would affect the penetration of ultraviolet rays and reduce the disinfection effect. By starting the extrusion motor, the first sprocket transmission assembly and the extrusion bidirectional threaded rod are driven to rotate, which causes the extrusion threaded sleeves on both sides to drive the extrusion drainage rollers to move relative to each other. By adjusting the distance between the two extrusion drainage rollers, excess cleaning liquid can be discharged when the flocked spunlace nonwoven fabric is conveyed, which facilitates the subsequent drying of the flocked spunlace nonwoven fabric.

[0023] 2. By setting up a disinfection and drying mechanism, not only can the bottom and top ultraviolet disinfection lamps be used to disinfect both sides of the flocked spunlace nonwoven fabric body, thereby improving the disinfection effect, but the lifting cylinder also drives the lifting plate and the pressing protective cover to descend, which can cover the disinfection area of ​​the flocked spunlace nonwoven fabric body, improving the safety of ultraviolet disinfection. After the flocked spunlace nonwoven fabric body is disinfected, the lowering of the lifting plate brings the clamping cover into contact with both sides of the first cleaning ring. Under the action of the clamping spring, the clamping pressing block can contact the top of the first cleaning ring. The clamping rotating rod realizes the rotation of the clamping cover, thereby clamping and fixing the first cleaning ring. The cleaning motor is started, driving the cleaning threaded rod to rotate, causing the cleaning threaded bracket to move, which in turn moves the second and first cleaning rings, thus improving the disinfection effect of the bottom ultraviolet lamp. The dust and stains on the surfaces of the outer and top UV disinfection lamps are cleaned to improve the disinfection effect of the bottom and top UV disinfection lamps. By adjusting the motor, the second sprocket transmission assembly and the adjusting rotating rod are rotated, causing the bevel gear transmission assembly to drive the adjusting bidirectional threaded rod to rotate. At the same time, the adjusting threaded sleeve drives the adjusting bracket to move relative to each other, which can adjust the distance between the two adjusting brackets. This keeps the third sprocket transmission assembly in a taut state, preventing the sprocket from dislodging when the third sprocket transmission assembly rotates, which would affect the rotation of the drying drum. By rotating the motor, the drying drum and the third sprocket transmission assembly can be driven to rotate synchronously. Under the action of the dryer body, hot air is blown from the drying air duct into the drying drum, thereby uniformly drying the flocked spunlace nonwoven fabric and improving the drying efficiency of the flocked spunlace nonwoven fabric.

The cleaning and disinfection mechanism 1 includes a cleaning tank 101, a drain valve 102 is fixedly installed on the bottom front of the cleaning tank 101, and a cleaning motor 103 is fixedly installed on the top of the cleaning tank 101 near the drain valve 102. The output end of the cleaning motor 103 is fixedly connected to a first cleaning roller 104, and the end of the first cleaning roller 104 is fixedly connected to a first meshing gear 105. The first meshing gear 105... A second meshing gear 106 is connected to the side, and a second cleaning roller 107 is fixedly installed on the outside of the second meshing gear 106. Moving cleaning liquid is placed inside the cleaning tank 101, and the flocked spunlace nonwoven fabric body 113 is wrapped around the outside of the first limiting roller 112, the first cleaning roller 104, and the second cleaning roller 107. The cleaning motor 103 is started to drive the first cleaning roller 104 and the first meshing gear 105 to rotate. Taking advantage of the meshing connection between the first meshing gear 105 and the second meshing gear 106, the second meshing gear 106 drives the second cleaning roller 107 to rotate. Since the first cleaning roller 104 and the second cleaning roller 107 rotate in opposite directions, the top and bottom sides of the flocked spunlace nonwoven fabric body 113 can be cleaned.

[0038] Please see Figures 2-4Several tension springs 108 are fixedly installed inside the first cleaning roller 104 and the second cleaning roller 107.

The two first limiting rollers 112 are respectively positioned vertically on both sides inside the cleaning box 101. Through the elastic force of the tension springs 108, the tension sliding rod 109 can drive the cleaning spiral blade 110 and the rubber scraper 111 to interact with the flocked spunlace nonwoven fabric. The surface of the fabric body 113 is bonded together. The rubber comb 111 can clean and collect the loose or unbonded fibers on the surface of the flocked spunlace nonwoven fabric body 113 on one side of the rubber comb 111. At the same time, the first cleaning roller 104 and the second cleaning roller 107 rotate in the opposite direction. The back of the rubber comb 111 can comb the fibers on the surface of the flocked spunlace nonwoven fabric body 113 to prevent the fibers from becoming frizzy, which would affect the finished quality and appearance of the flocked spunlace nonwoven fabric body 113. At the same time, the spiral characteristics of the cleaning spiral blade 110 can make the water flow spiral and collect the cleaned fibers for subsequent cleaning.

[0039] Please see Figures 2-6 The flocked spunlace nonwoven fabric body 113 is wound around the outside of the first limiting roller 112.

Extrusion threaded sleeves 119 are symmetrically threaded onto the outer ends of both extrusion threaded rods 118. Extrusion threaded sleeves 119 are rotatably connected between the two extrusion threaded sleeves 119. The drain roller 120 cleans the lint on the surface of the flocked spunlace nonwoven fabric body 113 in advance, preventing the lint from adhering to the surfaces of the bottom UV disinfection lamp 204 and the top UV disinfection lamp 213, thus affecting the penetration of ultraviolet rays and reducing the disinfection effect. By starting the extrusion motor 116, the first sprocket transmission assembly 117 and the extrusion bidirectional threaded rod 118 are rotated, causing the extrusion threaded sleeves 119 on both sides to drive the extrusion drain roller 120 to move relative to each other. By adjusting the distance between the two extrusion drain rollers 120, excess cleaning liquid can be discharged when the flocked spunlace nonwoven fabric body 113 is conveyed, which facilitates the subsequent drying of the flocked spunlace nonwoven fabric body 113.

[0040] Please see Figure 1 , Figures 6-7The disinfection and drying mechanism 2 includes a disinfection table 201. Protective baffles 202 are fixedly installed on both sides of the inside of the disinfection table 201.

A supporting top plate 224 is fixedly installed on the top of the drying bracket 223. After the flocked spunlace nonwoven fabric body 113 is disinfected, the lowering lifting plate 208 makes the clamping cover 220 contact the two sides of the first cleaning ring 205. Under the action of the clamping spring 218, the clamping pressing block 219 can contact the top of the first cleaning ring 205. The clamping rotating rod 221 is used to realize the rotation of the clamping cover 220, thereby clamping and fixing the first cleaning ring 205. The cleaning motor 214 is started to drive the cleaning threaded rod 215 to rotate, which moves the cleaning threaded bracket 216 and drives the second cleaning ring 217 and the first cleaning ring 205 to move at the same time.

[0042] Please see Figures 9-11A second sprocket limiting cover 225 is fixedly installed on one side of the drying workbench 222.

The second sprocket drive assembly 227 and the adjusting rotating rod 228 are driven to rotate by the adjusting motor 226, which in turn drives the bevel gear drive assembly 229 to rotate the adjusting double-threaded rod 230. At the same time, the adjusting threaded sleeve 231 drives the adjusting bracket 232 to move relative to each other, which can adjust the distance between the two adjusting brackets 232, so that the third sprocket drive assembly 235 is in a taut state. To prevent the sprocket from slipping when the third sprocket drive assembly 235 rotates, which would affect the rotation of the drying drum 233, the rotating motor 234 drives the drying drum 233 and the third sprocket drive assembly 235 to rotate, which can drive the two drying drums 233 to rotate synchronously. Under the action of the dryer body 237, hot air is blown from the drying air duct 236 into the drying drum 233, thereby uniformly drying the flocked spunlace nonwoven fabric body 113 and improving the drying efficiency of the flocked spunlace nonwoven fabric body 113.

[0043] Working principle: Before using this ultraviolet disinfection device for finished flocked spunlace nonwoven fabric, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 11As shown, firstly, a moving cleaning solution is placed inside the cleaning tank 101. The flocked spunlace nonwoven fabric body 113 is then wrapped around the outside of the first limiting roller 112, the first cleaning roller 104, and the second cleaning roller 107. The cleaning motor 103 is started, driving the first cleaning roller 104 and the first meshing gear 105 to rotate. Utilizing the meshing connection between the first meshing gear 105 and the second meshing gear 106, the second meshing gear 106 drives the second cleaning roller 107 to rotate. Through the first cleaning roller 104 and the second cleaning roller 107... The washing roller 107 rotates in the opposite direction, enabling it to clean the top and bottom sides of the flocked spunlace nonwoven fabric body 113. Through the elastic force of the tension spring 108, the tension sliding rod 109 drives the cleaning spiral blade 110 and the rubber scraper 111 to adhere to the surface of the flocked spunlace nonwoven fabric body 113. The rubber scraper 111 cleans and collects any loose or unadheded flocking fibers from the surface of the flocked spunlace nonwoven fabric body 113 on one side of the rubber scraper 111. Simultaneously, the first washing roller 104 rotates in the opposite direction. The second cleaning roller 107, through the back of the rubber comb 111, can comb the fluff on the surface of the flocked spunlace nonwoven fabric body 113, preventing the fluff from becoming frizzy, thus affecting the finished quality and appearance of the flocked spunlace nonwoven fabric body 113. At the same time, utilizing the spiral characteristics of the cleaning spiral blade 110, the water flow can be made to rotate in a spiral, which can collect the cleaned fluff for subsequent cleaning. By cleaning the fluff on the surface of the flocked spunlace nonwoven fabric body 113 in advance, it is possible to prevent the fluff from adhering to the bottom ultraviolet disinfection. The surfaces of the poison lamp 204 and the top ultraviolet disinfection lamp 213 affect the penetration of ultraviolet rays and reduce the disinfection effect. By starting the extrusion motor 116, the first sprocket transmission assembly 117 and the extrusion bidirectional threaded rod 118 are driven to rotate, so that the extrusion threaded sleeves 119 on both sides drive the extrusion drainage rollers 120 to move relative to each other. By adjusting the distance between the two extrusion drainage rollers 120, excess cleaning liquid can be discharged when the flocked spunlace nonwoven fabric body 113 is conveyed, which facilitates the subsequent drying of the flocked spunlace nonwoven fabric body 113.

[0044] Secondly, the bottom ultraviolet disinfection lamp 204 and the top ultraviolet disinfection lamp 213 are used to disinfect the two sides of the flocked spunlace nonwoven fabric body 113, thereby improving the disinfection effect of the flocked spunlace nonwoven fabric body 113. At the same time, the lifting cylinder 207 drives the lifting plate 208 and the pressing protective cover 212 to descend, which can cover the disinfection area of ​​the flocked spunlace nonwoven fabric body 113, improving the safety of ultraviolet disinfection. After the flocked spunlace nonwoven fabric body 113 is disinfected, the lifting plate 208 is lowered to make the clamping cover 220 contact the two sides of the first cleaning ring 205, and the clamping springs... Under the action of 218, the clamping and pressing block 219 can contact the top of the first cleaning ring 205. The clamping rotating rod 221 is used to rotate the clamping cover 220, thereby clamping and fixing the first cleaning ring 205. The cleaning motor 214 is started to drive the cleaning threaded rod 215 to rotate, which moves the cleaning threaded bracket 216 and drives the second cleaning ring 217 and the first cleaning ring 205 to move at the same time. This can clean the dust and stains on the surface of the bottom ultraviolet disinfection lamp 204 and the top ultraviolet disinfection lamp 213, and improve the disinfection effect of the bottom ultraviolet disinfection lamp 204 and the top ultraviolet disinfection lamp 213.

[0045] Finally, by adjusting the motor 226 to drive the second sprocket transmission assembly 227 and the adjusting rotating rod 228 to rotate, the bevel gear transmission assembly 229 drives the adjusting bidirectional threaded rod 230 to rotate. At the same time, the adjusting threaded sleeve 231 drives the adjusting bracket 232 to move relative to each other, which can adjust the distance between the two adjusting brackets 232, so that the third sprocket transmission assembly 235 is in a taut state, avoiding the phenomenon of sprocket tooth dislodging when the third sprocket transmission assembly 235 rotates, which would affect the rotation of the drying drum 233. By rotating the motor 234 to drive the drying drum 233 and the third sprocket transmission assembly 235 to rotate, the two drying drums 233 can be driven to rotate synchronously. Under the action of the dryer body 237, hot air is blown from the drying air duct 236 into the drying drum 233, thereby uniformly drying the flocked spunlace nonwoven fabric body 113 and improving the drying efficiency of the flocked spunlace nonwoven fabric body 113.
