Description

[0001] The present invention relates to the technical field of wet and dry towel processing, and more specifically, to processing equipment and processes for perforated wearable non-woven wet towels and dry towels. Background Art

[0002] Wet towels and dry towels have great advantages compared to existing paper towels. They not only have high toughness and good water absorption, but also are convenient to clean and have high comfort. Currently, in the prior art, wet towels and dry towels are mainly processed from non-woven fabrics, mainly including processes such as finishing, folding, cutting, stacking, and packaging. The production of wet towels also includes processes such as soaking and spraying the materials.

[0003] During the cutting process of wet towels and dry towels in the prior art, due to the high toughness of the non-woven fabric material, residual material fibers will remain during cutting.

[0045] Refer to Figure 7 As shown in, the blade 404 is designed in an arc shape, and there is a gap between the blade 404 and the inner side wall of the pneumatic box 402.

[0047] Referring to Figures 4-8 , the liquid supply assembly includes a liquid supply chamber 102 arranged on the frame 100. A liquid storage chamber 207 is arranged at the inner top of the gas storage block 200. A piston rod 208 is arranged inside the liquid storage chamber 207.

[0048] It should be noted that the bottom of the piston rod 208 is designed as a magnet structure, and a magnet attracting the piston rod 208 is arranged at the center of the piston block 205.

[0049] Referring to Figures 4-13 , the coating assembly includes a cleaning block 302, a first elastic block 303 and a second elastic block 304 arranged inside the cleaning slider 300.

[0052] The processing technology of the processing equipment for punching wearable non-woven wet wipes and dry wipes includes the following steps:

[0053] S1: Sort and inspect the non-woven fabric materials.

[0054] S2: Transport, fold, and disinfect the materials.

[0055] S3: Cut and punch the materials with the cutting knife 101 and the punching knife 103.

[0056] S4: Pack and seal the cut materials.

[0057] The working process of the processing equipment and technology for the perforated wearable non-woven wet wipes and dry wipes is as follows:

[0058] The wet wipe or dry wipe materials are transported by the conveying device on the frame 100 to be cut under the cutting knife 101. The air cylinder starts to push the cutting knife 101 down to cut the materials. The materials are cut by the cutting knife 101. During the downward movement of the cutting knife 101, the positioning block 105 first contacts the materials and assists and fixes the materials on both sides of the punching knife 103, improving the stability during the punching and cutting of the stacked materials and the neatness of the cut, and improving the processing quality. Subsequently, the punching knife 103 and the cutting knife 101 move down together, and the materials are punched by the punching knife 103. During this process, the positioning block 105 compresses the gas inside the fixing block 104 once and discharges the compressed gas into the gas storage block 200 through the pump gas pipe 106.

[0059] Furthermore, through the magnetic design at the top of the plugging block 203 and the chute 204, in the initial state, the plugging block 203 is adsorbed above the chute 204 to block the exhaust pipe 201. As the cutting process continues, the pump air pipe 106 continuously pumps air into the air storage block 200, increasing the internal pressure of the air storage block 200 and pushing the piston block 205 downward to exert pressure on the compression spring 206. The piston block 205 moves downward until it contacts the lower protrusion of the plugging block 203. When the piston block 205 moves further downward, it can push the plugging block 203 downward, increasing the distance between the top of the plugging block 203 and the top of the chute 204 and decreasing the magnetic force, causing the plugging block 203 to disengage from the magnetic connection with the top of the chute 204. Instead, the distance between the plugging block 203 and the bottom of the chute 204 becomes smaller and the magnetic force increases, enabling the rapid downward movement of the plugging block 203, causing the exhaust pipe 201 to be disengaged from the blockage of the plugging block 203. The gas inside the air storage block 200 is discharged into the interior of the pneumatic box 402 through the exhaust pipe 201 under the reset action of the compression spring 206 and is discharged into the buffer cavity 210 through the exhaust channel 403, pushing the buffer block 211 downward and compressing the spring connected to the buffer block 211. Since the inner diameter of the exhaust channel 403 is larger than the inner diameter of the air blowing pipe 212 and the elastic coefficient of the spring connected to the buffer block 211 is smaller than the elastic coefficient of the spring connected to the piston block 205, the gas inside the air storage block 200 can be quickly discharged into the buffer cavity 210 and slowly discharged through the air blowing pipe 212 via the reset of the buffer block 211. During this process, the blade 404 is pushed to rotate, and further, the driving shaft connecting the pneumatic box 402 and the runner 400 drives the runner 400 to rotate synchronously, thereby driving the conveyor belt 401 to move and driving the cleaning slider 300 to slide towards the blade at the bottom of the cutting knife 101.

[0060] When the cleaning slider 300 slides towards the blade of the cutting knife 101, the cleaning block 302 first contacts the blade. As the blade passes through the inclined edge of the cleaning block 302, the cleaning block 302 can be pushed away from the blade, causing the cleaning block 302 to clamp the blade when the cleaning slider 300 passes through the blade. When the cleaning slider 300 passes through the blade, the cleaning block 302 maintains a certain stress on the surface of the blade under the elastic force of the spring between the cleaning block 302 and the cleaning slider 300, enabling efficient cleaning of the blade surface, removing the material fiber debris and attached solvent on the blade surface during the cutting process, ensuring the cutting efficiency of the cutting knife 101, reducing the burrs and tearing phenomena during cutting, and improving the quality of material processing.

[0061] It should be noted that touch switches are provided at both the top and bottom of the sliding groove 204, and corresponding reactions are made when the plugging block 203 contacts the top or bottom of the sliding groove 204. When the plugging block 203 contacts the switch at the bottom of the sliding groove 204, it indicates that the piston block 205 is compressed to the limit, and the exhaust pipe 201 starts to exhaust. At this time, the touch switch controls the cylinder to stop driving the cutting knife 101 continuously during the next lifting action, facilitating the cleaning of the slider 300 to process the lifted cutting knife 101. When the piston block 205 resets and lifts the plugging block 203 so that the plugging block 203 rises to contact the touch switch at the top of the sliding groove 204 and plugs the exhaust pipe 201, the touch switch controls the cylinder to start again after a certain delay, providing enough time for the cleaning slider 300 to reset while resuming production.

[0062] During the reset and upward movement of the piston block 205, the pressure below the piston block 205 decreases. The chips and solvents cleaned by the cleaning slider 300 are sucked into the inside of the air storage block 200 through the chip discharge groove 305 and the suction pipe 202. At the same time, through the continuous exhaust of the air blowing pipe 212, the air blowing port 301 can blow the chip materials cleaned by the cleaning block 302 to reduce adhesion. Along with the absorption of the suction pipe 202, automatic collection of the cleaning materials is realized. When the piston block 205 resets and rises to contact the piston rod 208, as the piston block 205 continues to reset and rise, the piston rod 208 rises to pump the coating agent stored inside the liquid storage cavity 207 into the storage cavity 310 through the liquid supply pipe 209. At the same time, the spring connecting the piston slider 311 and the first elastic block 303 is compressed, and the coating agent fills the storage cavity 310. At the same time, the plugging block 203 is changed to be magnetically connected to the top of the sliding groove 204 to plug the exhaust pipe 201, facilitating subsequent cyclic operation.

[0063] It should be noted that a one-way valve is provided at the inner bottom of the air storage block 200 to discharge the inhaled liquid and gas, and the suction pipe 202 can be provided with a filter screen to filter and collect solid fiber collectibles.

[0064] It should be noted that when the piston block 205 moves downward, through the magnetic force between the piston rod 208 and the center of the piston block 205, the piston rod 208 is driven to move downward synchronously until the piston block 205 and the piston rod 208 are separated from adsorption, and the coating agent inside the liquid supply cavity 102 is sucked into the liquid storage cavity 207 through a one-way pipeline. During the reset process of the piston block 205, the coating agent inside the liquid storage cavity 207 can be pumped out through the one-way valve inside the liquid supply pipe 209 by the lifting of the piston block 205.

[0065] Meanwhile, after the piston block 205 resets to the highest position, the blade 404 that has lost gas supply resets and rotates together with the runner 400 under the elastic reset action of the coil spring 405, driving the cleaning slider 300 that has passed through the blade back to the initial position. During this process, the driving roller 306 rotates during the reset process by clamping with the blade, winds and tightens the second pulling rope 309, driving the cleaning block 302 to move towards the inside of the cleaning slider 300 so that it does not contact the blade during the reset process. Since the winding directions of the first pulling rope 308 and the second pulling rope 309 are opposite, the first pulling rope 308 is in a released and loosened state at this time. The first elastic block 303 extends under the elastic force connected to the cleaning slider 300, making the coating roller 307 stick to the blade during the reset process. The coating roller 307 rotates by the clamping and relative movement with the blade, dips and adsorbs the coating agent from the inside of the storage cavity 310 and coats it on the blade surface by rotation, and blows air through the air blowing port 301 to the coated area to accelerate the evaporation of the coating solvent. This can not only accelerate the drying and adhesion effect of the coating agent, but also accelerate the movement of the excess coating agent, making it accelerate to converge and drip, and be collected by the cleaning slider 300, improving the uniformity of the coating.

[0066] It should be noted that the coating agent is preferably a food-grade silicone oil coating, which has good lubricity and can reduce the friction between the blade and the processed material. It is not only relatively stable chemically and hardly reacts with common dry wipe and wet wipe materials, but also because the silicone oil itself has low volatility and a fast drying speed, the waiting drying time is short, and cutting can continue after coating, without leaving stains on the cut product or affecting the quality of the product.

[0067] It should be noted that the driving roller 306 can rotate by friction with the blade when passing through the blade, so that the rotation directions are opposite when moving forward and resetting. When moving towards the blade, the first pulling rope 308 tightens the first elastic block 303 to prevent the coating roller 307 from contacting the blade during the cleaning process. When the driving roller 306 resets and rotates in the reverse direction, the second pulling rope 309 tightens the cleaning block 302 to avoid affecting the coated area. Moreover, the rotation angle of the driving roller 306 is limited and it will not continue to rotate after rotating to a certain angle, preventing excessive rotation and tightening the cleaning block 302 and the first elastic block 303 at the same time.

[0068] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
