Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a non-woven fabric dipping device and a non-woven fabric. Background Art

[0002] A non-woven fabric is a non-woven fabric directly formed by fibers, which has wide applications in the fields of clothing, home decoration, agriculture, industry, etc. The non-woven fabric has good air permeability, filtration property, heat preservation property, water absorption property, waterproof property, stretchability, etc., and can also meet the requirement of light transmittance. Therefore, it has become the mainstream material in industrial covering fabrics and agricultural crop covering fabrics.

[0003] At present, a Chinese utility model patent application with a publication date of November 20, 2013 and a publication number of CN203295880U proposed a light-transmitting non-woven fabric, which includes a body layer and a silane-based coating liquid-cured light-transmitting chemical material coating; the body layer is located in the middle layer of the non-woven fabric; the silane-based coating liquid-cured light-transmitting chemical material coatings are respectively arranged on the upper and lower surfaces of the body layer; the body layer of the non-woven fabric is immersed in the coating liquid of the prepared light-transmitting chemical material coating, and after heat drying and curing treatment, a light-transmitting chemical material coating is formed on the surface of the non-woven fabric, improving the light transmittance of the non-woven fabric.

[0004] However, in the impregnation process of the non-woven fabric body layer and the curing process of the light-transmitting chemical material coating, since it is difficult to control the impregnation and curing time, and the transmission of the impregnated non-woven fabric is troublesome, the coating material coverage is insufficient and uneven, and the curing is incomplete, resulting in poor coverage effect of the light-transmitting chemical material coating and the light transmittance of the non-woven fabric cannot be improved well. Summary of the Utility Model

[0005] In order to enable the non-woven fabric to have light transmittance to a greater extent, the utility model provides a non-woven fabric dipping device and a non-woven fabric.

[0006] In a first aspect, the utility model provides a non-woven fabric dipping device, which includes a frame, a discharging machine, a processing mechanism and a winding mechanism. The processing mechanism includes an infiltration component and a drying component. The infiltration component includes an infiltration tank, a first rotating roller and a second rotating roller. The discharging machine is arranged on the frame, the infiltration tank is arranged on the frame, the first rotating roller is rotatably connected to the infiltration tank, the second rotating roller is slidably connected in the infiltration tank, the drying component is arranged on the frame, and the drying component is used for drying the infiltrated non-woven fabric. The winding mechanism is arranged on the frame, and the winding mechanism is used for winding the dried non-woven fabric.

[0007] After the non-woven fabric is manufactured by the discharging machine, the initial end of the non-woven fabric is placed on the first rotating roller. Then, the second rotating roller is slid upward so that the initial end of the non-woven fabric passes under the second rotating roller, and the second rotating roller presses the non-woven fabric in the impregnation tank, and dye is added to the impregnation tank. Then, the initial end of the non-woven fabric passes through the drying mechanism. After drying, the non-woven fabric is wound by the winding mechanism. During this process, the non-woven fabric can be fully unfolded, so that the light-transmitting chemical dressing can be fully attached to the surface of the non-woven fabric, thereby effectively improving the light transmittance of the non-woven fabric.

[0008] Optionally, the impregnation assembly further includes a first slider. A chute is provided on the impregnation tank. The first slider is slidably connected in the first chute, and the second rotating roller is provided on the first slider.

[0009] By adopting the above technical solution, after the initial end of the non-woven fabric is placed on the first rotating roller, the first slider slides in the first chute to the upper part of the impregnation tank, waiting for the initial end of the non-woven fabric to pass under the second rotating roller. Subsequently, the first slider slides in the first chute to the lower part of the impregnation tank, so that the non-woven fabric is impregnated. During this process, the first slider drives the second rotating roller to slide downward, avoiding the lighter non-woven fabric floating on the surface of the chemical dressing and not being fully immersed, thereby effectively improving the impregnation effect.

[0010] Optionally, the impregnation assembly further includes a first scraper and a second scraper, and both the first scraper and the second scraper are provided in the impregnation tank.

[0011] By adopting the above technical solution, after the non-woven fabric is impregnated, the non-woven fabric saturated with the chemical dressing passes between the first scraper and the second scraper. The first scraper and the second scraper can respectively scrape off the excess chemical dressing on the upper and lower layers of the non-woven fabric evenly. This can not only ensure that the chemical dressing is fully and evenly attached to the non-woven fabric body layer to form a uniform and complete light-transmitting chemical material coating, but also ensure that the non-woven fabric to be dried is relatively dry, thus facilitating the treatment of the non-woven fabric and enhancing the light transmittance of the non-woven fabric.

[0012] Optionally, the drying assembly includes a drying box, a box cover, a handle, a blower, a first adjusting roller, a second adjusting roller, and a third rotating roller. The first adjusting roller is rotatably connected to one end of the drying box, the second adjusting roller is rotatably connected to the other end of the drying box, the third rotating roller is rotatably connected inside the drying box, there are multiple third rotating rollers, the blower is provided on the drying box, the box cover is hinged to one side of the drying box, and the handle is provided above the box cover.

[0013] By adopting the above technical solution, first pull the handle to open the box cover, press the non-woven fabric above the first adjusting roller, then bypass the third rotating roller in sequence, and finally pass above the second adjusting roller. After the non-woven fabric is placed, pull the handle again to close the box cover. The multiple third rotating rollers inside the drying box can make the non-woven fabric arranged smoothly over a long distance, ensuring that a sufficient length of non-woven fabric is dried simultaneously, accelerating the processing efficiency of the non-woven fabric, ensuring that the processing effects of non-woven fabrics in the same batch are consistent, and the blower can enhance the circulation rate of the hot air flow, which can promote the acceleration of the curing speed of the light-transmitting chemical material coating, thereby increasing the high light transmittance of the non-woven fabric.

[0014] Optionally, the drying assembly further includes a temperature sensor and a display screen. The temperature sensor is arranged in the drying box, the display screen is arranged on the drying box, and the temperature sensor is electrically connected to the display screen.

[0015] By adopting the above technical solution, the temperature inside the drying box body is displayed on the display screen, which is convenient for manual observation. When the temperature inside the box is too low or too high, the rotation speed of the blower can be increased or decreased accordingly to control the temperature inside the box, avoiding the influence on the drying degree of the light-transmitting chemical material coating due to uneven temperature inside the drying box.

[0016] Optionally, the winding mechanism includes a winding roller, a pressing roller, a limiting plate and a driving motor. The pressing roller is rotatably connected to the frame, the limiting plate is arranged on the frame, a groove is formed on the limiting plate, both ends of the winding roller are slidably connected in the groove, and the winding roller abuts against the pressing roller. The driving motor is arranged on the frame, and the driving motor is in transmission connection with the pressing roller.

[0017] By adopting the above technical solution, the non-woven fabric that has completed the impregnation and drying treatment is pressed on the surface of the winding roller. At this time, both ends of the winding roller are located at the lower end of the groove of the limiting plate, and the pressing roller abuts against the winding roller. Then, the driving motor drives the pressing roller to rotate. As the thickness of the wound non-woven fabric roll increases, the winding roller slides upward along the groove of the limiting plate, so as to press and smooth the non-woven fabric being wound throughout the process, making the non-woven fabric tighten smoothly, preventing the non-woven fabric from being stretched, thereby avoiding the formation of damage to the light-transmitting chemical material coating on the non-woven fabric due to stretching, maintaining the integrity of the light-transmitting chemical material coating. At the same time, the winding process driven by the motor can eliminate the manual winding step. On the one hand, it improves the overall processing efficiency of the non-woven fabric, and on the other hand, it reduces the number of times of contact with the processed non-woven fabric, avoiding damage to the chemical material coating, thereby enhancing the integrity of the light-transmitting chemical material coating and achieving the purpose of improving the light transmittance of the non-woven fabric.

[0018] Optionally, fixed baffles are further arranged on both sides of the pressing roller.

[0019] By adopting the above technical solution, during the winding process, the baffles are fixed at both ends of the pressing roller. When winding, both sides of the non-woven fabric contact the baffles, preventing the non-woven fabric from skewing during winding, thereby avoiding creases on the non-woven fabric and causing breaks in the formed light-transmitting chemical material coating, thus improving the light transmittance of the non-woven fabric.

[0020] In a second aspect, the present utility model provides a non-woven fabric, which includes a non-woven fabric body layer and a high light-transmitting chemical material coating; the high light-transmitting chemical material coating is attached to the surface of the non-woven fabric body layer.

[0021] By adopting the above technical solution, a layer of light-transmitting chemical material is evenly attached to both the upper and lower surfaces of the non-woven fabric, thereby enhancing the high light transmittance of the non-woven fabric.

[0022] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0023] 1. The second rotating roller presses the non-woven fabric in the impregnation tank and injects dye into the impregnation tank. During this process, the non-woven fabric can be fully unfolded, enabling the light-transmitting chemical dressing to fully adhere to the surface of the non-woven fabric, thereby effectively improving the light transmittance of the non-woven fabric.

[0024] 2. The first squeegee and the second squeegee can respectively scrape off the excess chemical dressing on the upper and lower layers of the non-woven fabric evenly. This can not only ensure that the chemical dressing adheres to the non-woven fabric body layer fully and evenly, forming a uniform and complete light-transmitting chemical material coating, but also ensure that the non-woven fabric about to enter the drying process is relatively dry. At the same time, when facing different processing requirements, different degrees of water scraping requirements can be achieved by changing the rotation angle of the wiper blade.

[0025] 3. The non-woven fabric that has completed the impregnation and drying processes is pressed on the surface of the winding roller. At this time, both ends of the winding roller are located at the lower ends of the grooves of the limiting plate, and the pressing roller abuts against the winding roller. Subsequently, driven by the rotation of the driving motor, the pressing roller rotates. As the thickness of the wound non-woven fabric roll increases, the winding roller slides upward along the groove of the limiting plate, thereby pressing and smoothing the non-woven fabric being wound throughout the process, enabling the non-woven fabric to be smoothly tightened, preventing the non-woven fabric from being stretched, and thus avoiding damage to the light-transmitting chemical material coating on the non-woven fabric due to stretching, maintaining the integrity of the light-transmitting chemical material coating. At the same time, the winding process driven by the motor can eliminate the manual winding step. On the one hand, it improves the overall processing efficiency of the non-woven fabric, and on the other hand, it reduces the number of contacts with the already processed non-woven fabric, avoiding damage to the chemical material coating, thereby enhancing the integrity of the light-transmitting chemical material coating and achieving the purpose of improving the light transmittance of the non-woven fabric.

Specific embodiments

[0031] The following is combined with Figures 1 - 4 to further elaborate on the present utility model in detail.

[0032] Embodiment 1:

[0033] This embodiment discloses a non-woven fabric impregnation device: Refer to Figures 1 - 3 , a non-woven fabric impregnation device includes a frame 100, a discharging machine 200, a processing mechanism 300, and a winding mechanism 400. The processing mechanism 300 is used for impregnating and drying the non-woven fabric, and the winding mechanism 400 is used for winding the processed non-woven fabric.

[0034] Refer to Figures 1 - 3, the processing mechanism 300 includes an infiltration component 310 and a drying component 320. The infiltration component 310 and the drying component 320 are arranged on the frame 100. The infiltration component 310 includes an infiltration tank 312, a first rotating roller 311, a second rotating roller 315, a first slider 313, a first scraper 316 and a second scraper 317. The infiltration tank 312 is arranged on the frame 100. The first rotating roller 311 is rotatably connected to the infiltration tank 312. The second rotating roller 315 is slidably connected in the infiltration tank 312. A chute is formed on the infiltration tank 312. The first slider 313 is slidably connected in the first chute 314. The second rotating roller 315 is arranged on the first slider 313. The first scraper 316 and the second scraper 317 are both arranged in the infiltration tank 312. The drying component 320 includes a drying box 321, a box cover 328, a handle 329, a blower 323, a first adjusting roller 322, a second adjusting roller 325, a third rotating roller 326, a temperature sensor 324 and a display screen 327. The first adjusting roller 322 is rotatably connected to one end of the drying box 321. The second adjusting roller 325 is rotatably connected to the other end of the drying box 321. The third rotating roller 326 is rotatably connected inside the drying box 321. There are multiple third rotating rollers 326. The blower 323 is arranged on the drying box 321. The box cover 328 is hinged to one side of the drying box 321. The handle 329 is arranged above the box cover 328. The temperature sensor 324 is arranged in the drying box 321. The display screen 327 is arranged on the drying box 321. The temperature sensor 324 is electrically connected to the display screen 327.

[0035] When starting the infiltration process, after the initial end of the non-woven fabric is placed on the first rotating roller 311, the first slider 313 slides in the first chute 314 to the upper part of the infiltration tank 312, waiting for the initial end of the non-woven fabric to pass under the second rotating roller 315. Subsequently, the first slider 313 slides in the first chute 314 to the lower part of the infiltration tank 312, enabling the non-woven fabric to complete infiltration. During this process, the first slider 313 drives the second rotating roller 315 to slide downward. After the non-woven fabric completes the impregnation process, let the non-woven fabric saturated with the chemical dressing pass between the first scraper 316 and the second scraper 317. The first scraper 316 and the second scraper 317 can respectively scrape off the excess chemical dressing on the upper and lower layers of the non-woven fabric evenly. After the non-woven fabric comes out of the infiltration component 310, it starts to enter the drying component 320. First, pull the handle 329 to open the box cover 328, press the non-woven fabric above the first adjusting roller 322, then bypass the third rotating roller 326 in sequence, and finally pass above the second adjusting roller 325. After the non-woven fabric is arranged properly, pull the handle 329 again to close the box cover 328. Subsequently, the blower 323, the temperature sensor 324 and its display screen 327 start to work, and the temperature inside the drying box 321 is displayed on the display screen 327 for observation.

[0036] Refer to Figure 3The winding mechanism 400 includes a winding roller 402, a pressure roller 401, a limit plate 404 and a driving motor 406. The pressure roller 401 is rotatably connected to the frame 100. The limit plate 404 is arranged on the frame 100. A groove 405 is opened on the limit plate 404. Both ends of the winding roller 402 are slidably connected in the groove 405, and the winding roller 402 abuts against the pressure roller 401. The driving motor 406 is arranged on the frame 100. The driving motor 406 is transmission-connected to the pressure roller 401. Fixed baffles 403 are also arranged on both sides of the pressure roller 401.

[0037] During the winding process, the non-woven fabric that has completed the impregnation and drying process is pressed onto the surface of the winding roller 402. At this time, the two ends of the winding roller 402 are located at the lower ends of the groove 405 of the limit plate 404, and the pressure roller 401 is in contact with the winding roller 402. Then, the pressure roller 401 is driven to rotate under the rotation of the driving motor 406. As the thickness of the wound non-woven fabric roll increases, the winding roller 402 slides upward along the groove 405 of the limit plate 404, thereby pressing and smoothing the non-woven fabric being wound throughout the process, so that the non-woven fabric is smoothly tightened. At the same time, the baffle 403 is fixed at both ends of the pressure roller 401. When winding, the two sides of the non-woven fabric are in contact with the baffle 403 to ensure that the non-woven fabric does not skew during winding.

[0038] In this embodiment 1, a non-woven fabric impregnation device is implemented as follows:

[0039] After the non-woven fabric is manufactured by the discharging machine 200, the initial end of the non-woven fabric is placed on the first rotating roller 311 of the infiltration mechanism. The first slider 313 slides through the groove 405 in the first chute 314 to the upper part of the infiltration box 312. The non-woven fabric winds through under the second rolling roller, and a light-transmitting chemical dressing is injected into the infiltration box 312. The first slider 313 slides downward again through the groove 405 in the first chute 314 to the lower part of the infiltration box 312, and the non-woven fabric is driven to the lower part inside the box and is completely immersed in the light-transmitting chemical dressing. When the infiltration time of the non-woven fabric reaches, the non-woven fabric passes between the first squeegee 316 and the second squeegee 317, and the excess chemical dressing on the upper and lower surfaces is scraped off by the squeegees. Then, the handle 329 above the cover of the drying box 321 is pulled to lift the box cover 328. The non-woven fabric is pressed on the first adjusting roller 322 of the drying box 321, passes above the first adjusting roller 322 and then passes through a number of third rotating rollers 326 inside the drying box 321 from left to right to reach the second adjusting roller 325. The handle 329 is pulled again to close the box cover 328. The blower 323, the temperature sensing device and its display screen 327 are turned on in sequence. The blower 323 starts the drying work, and the temperature inside the drying box 321 is displayed on the display screen 327 in real time. The non-woven fabric after the drying treatment then passes above the second adjusting roller 325 to reach the winding mechanism 400. The winding roller 402 slides to the lowermost part of the limiting plate 404, presses the non-woven fabric on the winding roller 402, and the driving motor 406 is turned on to drive the pressing rollers 401 located on both sides of the winding roller 402 to start working. The baffles 403 at both ends of the winding roller 402 limit the rolling direction of the non-woven fabric. The thickness of the wound non-woven fabric increases, and the winding roller 402 slides upward along the groove 405 on the limiting plate 404, and the pressing rollers 401 always rotate closely against the non-woven fabric roll.
