Description

Technical Field

[0001] This utility model relates to the field of wet wipe manufacturing technology, and in particular to wet wipe production equipment that integrates non-woven fabric. Background Technology

[0002] Wet wipes are paper towels made from pure water and spunlace nonwoven fabric, etc., used for wiping the face, hands, or other parts of the skin. Common wet wipes include hand wipes, face wipes, and wet wipes.

[0003] Traditional wet wipe production involves transporting finished nonwoven fabric to a wet wipe manufacturing factory, where the nonwoven fabric undergoes unwinding, embossing, vertical slitting, folding, horizontal slitting, weighing and replenishing liquid, and finally packaging. The corresponding equipment includes an unwinding machine, embossing machine, vertical slitting machine, folding machine, horizontal slitting machine, weighing and replenishing liquid mechanism, and packaging machine. The unwinding machine, embossing machine, vertical slitting machine, folding machine, horizontal slitting machine, weighing and replenishing liquid mechanism, and packaging machine are arranged sequentially along the nonwoven fabric conveying direction.

[0004] The functions of each piece of equipment are as follows: the unwinding machine unwinds the nonwoven fabric; the embossing machine performs embossing operations on the surface of the nonwoven fabric; the vertical slitting machine cuts the nonwoven fabric into multiple strips along its width; the folding machine folds the corresponding strips of nonwoven fabric; the horizontal slitting machine cuts the corresponding strips of nonwoven fabric to a certain length; the weighing and replenishing machine injects EDI pure water into the dried nonwoven fabric to form wet wipes; and finally, the packaging machine packages the wipes into finished products.

[0005] The existing nonwoven fabric manufacturing process involves melting wood pulp and viscose fiber into a paste, then filtering, beating, laying the web, hydroentangling, and finally drying and winding. The equipment involved includes a melting tank, beating machine, web laying machine, hydroentangling machine, and winding machine.

[0006] After the nonwoven fabric is produced in the nonwoven fabric production area, it is rolled into a roller and then transported to the wet wipe production site for wet wipe production. The problem with the existing wet wipe production method is that the production of nonwoven fabric raw materials is not strongly linked to the production of finished wet wipes. The transfer link of nonwoven fabric rollers will increase the cost significantly. At the same time, in the traditional nonwoven fabric hydroentangling production process, the water after hydroentangling needs to be dried, which not only consumes energy but also wastes water resources. Utility Model Content

[0007] The purpose of this invention is to provide a wet wipe production equipment that integrates non-woven fabric production, in order to solve the technical problem that the production of non-woven fabric raw materials and the production of finished wet wipes are independent of each other in the existing technology, which requires the non-woven fabric roller to be transferred between two sites, thus increasing the manufacturing cost of wet wipes.

[0008] To solve the above-mentioned technical problems, the technical solution of the wet wipe production equipment integrating non-woven fabric in this utility model is as follows:

[0009] The integrated nonwoven fabric wet wipe production equipment includes a nonwoven fabric production device and a wet wipe production device arranged in sequence. The nonwoven fabric production device includes a molten ladle, a pulping machine, a web forming machine, and a hydroentangling machine arranged in sequence. The wet wipe production device includes a cutting device, a folding machine, and a packaging machine located downstream of the folding machine. The nonwoven fabric formed by the hydroentangling machine is processed by the cutting device and the folding machine and then enters the packaging machine. The nonwoven fabric production device also includes a molten ladle wet wipe solution filling device for injecting wet wipe solution into the molten ladle. The nonwoven fabric production device also includes a hydroentangling machine wet wipe solution supply device for supplying wet wipe solution to the hydroentangling nozzles of the hydroentangling machine. The nonwoven fabric production device also includes a wet wipe solution recovery device for recovering the sprayed liquid from the hydroentangling nozzles.

[0010] Furthermore, the cutting device includes a vertical cutting mechanism located upstream of the folding machine and a horizontal cutting mechanism located downstream of the folding machine.

[0011] Furthermore, the wet wipe making device also includes a weighing and replenishing mechanism located between the transverse cutting mechanism and the packaging machine.

[0012] Furthermore, the wet wipe solution is composed of EDI pure water and additives.

[0013] Furthermore, the additives consist of at least one of the following: moisturizers, preservatives, antibacterial agents, nonionic surfactants, bactericides, and essences.

[0014] Furthermore, the wet wipe solution recycling device includes a wet wipe solution recycling tank, which is connected to the wet wipe solution filling device in the molten ladle and / or the wet wipe solution supply device in the hydroentanglement machine via a water pump.

[0015] Furthermore, the wet wipe manufacturing apparatus also includes a calendering machine located downstream of the hydroentangling machine, the calendering machine including calendering rollers for pressing and calendering the upper and lower sides of the nonwoven fabric.

[0016] Furthermore, the spunlace nozzle includes an upper spunlace nozzle located on the upper side of the nonwoven fabric and a lower spunlace nozzle located on the lower side of the nonwoven fabric. The wet wipe liquid preparation and recovery device includes an upper water-blocking cover surrounding the upper spunlace nozzle and a lower water-blocking cover surrounding the lower spunlace nozzle. The openings of the upper and lower water-blocking covers face each other, and the bottom of the lower water-blocking cover is provided with a drain hole for the water-blocking cover connected to the wet wipe liquid preparation and recovery box.

[0017] Furthermore, the projection of the opening of the upper water shield along the vertical direction is located within the opening of the lower water shield.

[0018] The beneficial effects of this utility model are as follows: This utility model integrates the production of nonwoven fabric and wet wipes, avoiding the increased costs associated with the transfer of nonwoven fabric. Specifically, during the nonwoven fabric production process, wet wipe solution is directly used to melt the wood pulp and viscose fiber, preventing the introduction of impurities during the nonwoven fabric production process and ensuring that the final wet wipe contains only the wet wipe solution. When the nonwoven fabric is hydroentangled using a hydroentangling machine, the liquid introduced into the hydroentangling machine is the wet wipe solution, further preventing the introduction of impurities during the nonwoven fabric production process. The jet liquid generated by the hydroentangling machine is recycled and reused by the wet wipe solution recovery device, reducing the cost of using the wet wipe solution. The hydroentangled nonwoven fabric is directly cut, folded, and packaged, thus eliminating the need for re-drying, winding, and transfer of the nonwoven fabric in existing technologies, significantly reducing the production cost of wet wipes. In existing technologies, after hydroentangling of nonwoven fabric, drying is required, which is not only energy-intensive but also wastes water resources. Attached Figure Description

[0025] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0026] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0027] An example of the implementation of the wet wipe production equipment integrating non-woven fabric in this utility model is... Figures 1-3 As shown:

[0028] It includes a nonwoven fabric making device and a wet wipe making device arranged in sequence.

[0029] The nonwoven fabric manufacturing apparatus includes a molten ladle 3, a pulping machine 5, a web-laying machine 6, and a hydroentangling machine arranged sequentially. The apparatus also includes a molten ladle wet wipe solution filling device 4 for injecting wet wipe solution into the molten ladle. The molten ladle wet wipe solution filling device 4 includes a filling tank containing the wet wipe solution. The apparatus further includes a hydroentangling machine wet wipe solution supply device 16, used in conjunction with the hydroentangling machine, for supplying pressurized wet wipe solution to the hydroentangling nozzles of the hydroentangling machine.

[0030] The nonwoven fabric manufacturing apparatus also includes a wet wipe liquid recovery device 12 for recovering the sprayed liquid from the hydroentanglement nozzles.

[0031] The spunlace nozzle includes an upper spunlace nozzle 18 located on the upper side of the nonwoven fabric 19 and a lower spunlace nozzle 21 located on the lower side of the nonwoven fabric. The wet wipe liquid preparation and recovery device includes an upper water baffle 17 covering the upper spunlace nozzle and a lower water baffle 22 covering the lower spunlace nozzle. The openings of the upper water baffle 17 and the lower water baffle 22 face each other. A water baffle drain hole 23 is provided at the bottom of the lower water baffle, and a fiber filter screen is provided at the water baffle drain hole 23.

[0032] The projection of the opening of the upper water baffle 17 along the vertical direction is located inside the opening of the lower water baffle 22. In this way, the jet liquid sprayed by the lower water spun nozzle is blocked by the upper water baffle after it acts on the non-woven fabric, and then flows down the inner wall of the upper water baffle to the lower water baffle 22. The jet liquid sprayed by the upper water spun nozzle is directly received by the lower water baffle 22 after it acts on the non-woven fabric.

[0033] The wet wipe solution recycling device includes a wet wipe solution recycling tank 24, which is connected to the wet wipe solution filling device 4 in the molten lava pool and the wet wipe solution supply device 16 in the hydroentanglement machine via a water pump 25. The drain hole 23 of the water shield is connected to the wet wipe solution recycling tank.

[0034] The wet wipe manufacturing apparatus includes a cutting device, a folding machine 11, and a packaging machine 15 located downstream of the folding machine. The non-woven fabric formed by the hydroentangling machine is processed by the cutting device and the folding machine before entering the packaging machine. The cutting device includes a vertical slitting mechanism 10 located upstream of the folding machine and a horizontal slitting mechanism 13 located downstream of the folding machine. The vertical and horizontal slitting mechanisms are prior art and will not be described in detail here; the folding machine and the packaging machine are also prior art and will not be described in detail here.

[0035] The wet wipe manufacturing device also includes a weighing and replenishing mechanism 14 disposed between the transverse slitting mechanism and the packaging machine. The function of the weighing and replenishing mechanism 14 is to weigh the folded and transversely cut wet wipes. Since the mass of a unit volume of nonwoven fabric is fixed (let's assume this weight is m1), the nonwoven fabric containing the wet wipe solution weighs m2. By comparing m1 and m2, the wet wipe solution content per unit volume of nonwoven fabric can be calculated. If the calculated wet wipe solution content is insufficient, the weighing and replenishing mechanism can inject the wet wipe solution into the nonwoven fabric to meet the required content. The specific structure of the weighing and replenishing mechanism is prior art. The difference between the weighing and replenishing mechanism in this invention and the prior art lies in their operating environment. The prior art weighing and replenishing mechanism bears the weight of dry nonwoven fabric and then injects the wet wipe solution into it; therefore, the prior art weighing and replenishing mechanism requires continuous replenishment. In this invention, the wet nonwoven fabric is weighed and then replenished with liquid as needed. Theoretically, the wet nonwoven fabric may already contain enough liquid to meet the requirements for wet wipe preparation. Therefore, the replenishment tube of the weighing and replenishment mechanism does not need to be constantly working.

[0036] The wet wipe manufacturing apparatus also includes a calendering machine located downstream of the hydroentangling machine. The calendering machine includes calendering rollers 26 used to calender the upper and lower sides of the nonwoven fabric. The calendering rollers 26 are used to calender the surface of the nonwoven fabric. While calendering rollers are also present in the prior art, their function in this invention differs from that in the prior art. In the prior art, calendering rollers calender dry nonwoven fabric, while in this invention, they calender wet nonwoven fabric. Therefore, in addition to calendering the nonwoven fabric, the calendering rollers can also squeeze out excess wet wipe liquid from the nonwoven fabric, preventing excessive wet wipe liquid content in the nonwoven fabric. To avoid waste of wet wipe liquid during the calendering process, this invention includes a calendering roll liquid recovery device located on the lower side of the calendering roll. The calendering roll liquid recovery device includes a liquid recovery tank located on the lower side of the calendering roll, which collects and reuses the wet wipe liquid extruded from the calendering roll, thus avoiding waste of wet wipe liquid.

[0037] In this invention, the wet wipe solution is composed of pure water and additives, and the additives are composed of at least one of the following: humectant, preservative, antibacterial agent, nonionic surfactant, bactericide, and essence.

[0038] The pulping machine, web-laying machine, and hydroentangling machine are all existing technologies. The innovation of this utility model lies in the use of wet wipe solution to complete the melting of wood pulp and viscose fiber in the melting pool. After initial filtration, the pulp is beaten by the pulping machine, then laid into a web by the web-laying machine, and finally hydroentangled and wound into shape by the hydroentangling machine. The hydroentangling machine's nozzles spray the wet wipe solution onto the nonwoven fabric. Throughout the entire process, no non-wet wipe finished liquids other than the wet wipe solution are introduced. The sprayed liquid from the hydroentangling machine can also be recycled and reused by the wet wipe solution recycling device. The recycled wet wipe solution can be sent to the wet wipe solution filling device in the melting pool and the wet wipe solution supply device in the hydroentangling machine for reuse, reducing the waste of wet wipe solution.

[0039] After the non-woven fabric is mixed with the wet wipe solution, it does not require drying and rolling. Instead, it is directly fed into the wet wipe production device. There, it undergoes embossing by a embossing machine, cutting by a vertical cutting mechanism, folding by a folding machine, and cutting by a horizontal cutting mechanism. After being processed by a weighing and replenishing mechanism, it is then packaged by a packaging machine. This process completely eliminates the need for drying and rolling in the non-woven fabric production process, and also eliminates the need for transferring the non-woven fabric rollers. The raw materials, in the form of wood pulp and viscose fiber, enter the wet wipe production equipment, and the final product is packaged wet wipes. This effectively reduces the increased transportation and storage costs associated with non-woven fabric handling.

[0040] A wet wipe production process using wet wipe production equipment.

[0041] The wet wipe production equipment is the same as the embodiments of the aforementioned wet wipe production equipment, and will not be described in detail here.

[0043] S11. Add wood pulp and viscose fiber to the molten pulp tank, and add wet wipe solution to the molten pulp tank through the wet wipe solution dispensing device to complete the pulping process.

[0045] S12. After the slurry is melted, it is beaten by a pulping machine and laid into a web by a web-laying machine before entering the hydroentangling machine. The hydroentangling machine's wet wipe liquid preparation and supply device supplies liquid to the hydroentangling nozzles of the hydroentangling machine. The hydroentangling nozzles spray the wet wipe liquid onto the nonwoven fabric, causing the nonwoven fabric to hydroentangle. The wet wipe liquid preparation and recovery device recovers the liquid sprayed from the hydroentangling nozzles and sends the recovered liquid to the wet wipe liquid preparation and filling device in the molten slurry pool and / or the hydroentangling machine's wet wipe liquid preparation and supply device.

[0046] Nonwoven fabrics made through water stimulation have a water content of 0.1 to 6 times the base weight of the nonwoven fabric, which can be controlled by hydroentangling pressure and hydroentangling time.

[0047] S13. The nonwoven fabric, after being hydroentangled by the hydroentangling machine, is fed into the calendering machine of the wet wipes making device for calendering.

[0048] S2, Making wet wipes

[0049] S21, after the nonwoven fabric is embossed, it is slit by a vertical slitting mechanism, then folded by a folding machine, and finally slit by a horizontal slitting mechanism.
