Description

Technical Field

[0001] The utility model relates to the technical field of wet wipe production, in particular to a non-contact wet wipe liquid adding device. Background Art

[0002] In the field of wet wipe production, the liquid adding process of wet wipes is a crucial link, which is a key step to ensure the quality, liquid absorption effect and use experience of wet wipes. It directly affects the wetness, use effect and final product quality of wet wipes. Traditional wet wipe liquid adding methods mostly adopt contact liquid adding, that is, directly spraying or smearing the liquid on the surface of wet wipes or adopting immersion liquid adding. However, this contact liquid adding method has many deficiencies, such as uneven liquid adding, serious liquid waste, and easy damage to wet wipes.

[0003] With the progress of technology and the improvement of consumer demands, the requirements for wet wipe liquid adding technology are also getting higher and higher. Non-contact liquid adding technology has gradually attracted the attention of the industry due to its unique advantages. The non-contact liquid adding technology realizes the uniform spraying of liquid by controlling parameters such as the angle and width of the liquid adding device, avoiding the direct contact between the wet wipes and the liquid adding device, thus reducing the damage to the wet wipes and the waste of liquid. However, the existing non-contact liquid adding devices still have limitations in the adjustment of the liquid adding angle and width, and cannot be adjusted in real time according to the actual situation of the material, resulting in unsatisfactory liquid adding effect. In addition, there are also deficiencies in the liquid supply control of traditional wet wipe liquid adding devices. These devices usually lack precise flow control and speed regulation mechanisms, and cannot achieve precise control of the liquid adding amount to the wet wipes. This leads to the following problems: 1. Unstable liquid adding amount: Due to the lack of precise flow control, traditional liquid adding devices often cannot maintain a stable liquid adding amount. This will cause large fluctuations in the liquid adding amount during the transmission of wet wipes, affecting the quality and production efficiency of wet wipes. 2. Difficult to adapt to different production requirements: Since the liquid adding amount cannot be adjusted according to the actual situation of the production line, traditional liquid adding devices often have difficulty adapting to the production requirements of wet wipes of different specifications and materials. This limits its application range and reduces the versatility and flexibility of the equipment. Therefore, it is of great significance to develop a non-contact wet wipe liquid adding device that can adjust the liquid adding angle and width in real time to improve the production efficiency and product quality of wet wipes. Summary of the Utility Model

[0004] To solve the above problems, the present utility model proposes a novel wet wipe liquid adding component. By setting an adjustable liquid adding pipe and a liquid supply device, the present liquid adding component realizes flexible adjustment of the liquid adding angle and width, as well as precise control of the liquid adding amount. Specifically, a plurality of liquid outlet holes are formed in the outer side wall of the liquid adding pipe along the length direction, and the number and position of the liquid outlet holes can be adjusted according to needs, so as to change the liquid adding width and angle. At the same time, the liquid supply device includes a liquid supply hose, a liquid supply main pipe and a plurality of liquid supply branch pipes. A flow meter and a speed regulating valve are arranged on each liquid supply branch pipe, which can monitor and control the liquid adding amount in real time, ensuring that the wet wipes can absorb the liquid evenly and stably during the transmission process. Through the wet wipe liquid adding component of the present utility model, precise control of the wet wipe liquid adding process can be realized, the quality and production efficiency of the wet wipes can be improved, the production cost can be reduced, and the market demand for high-quality wet wipes can be met.

Detailed Embodiment

[0025] In the description of the present utility model, it should also be noted that unless otherwise clearly defined and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] In the existing liquid adding method, the liquid adding pipe is inserted through the non-woven fabric or wet toilet paper, and the non-woven fabric or wet toilet paper is directly humidified during the transportation process. Since the liquid adding pipe is fixed and has a large resistance, the situation of pulling and thinning or breaking the cloth often occurs, which not only affects the production efficiency but also causes waste of materials. In addition, there is also the immersion liquid adding method. For example, CN117188066A, a liquid adding device for automatic liquid adding in wet wipe production, discloses a liquid adding device for automatic liquid adding in wet wipe production, including a liquid adding table. A liquid adding component is provided at the bottom end of the liquid adding table, a conveying box is provided at the end of the liquid adding table, a liquid adding box for adding liquid to the wet wipes is provided on the bottom side inside the conveying box, and a squeezing frame is provided on the right side of the end of the liquid adding box. By the action of the A cylinder pushing the stabilizing plate member downward and immersing the fixing frame and the wet wipe liquid adding conveying roller into the liquid, the wet wipe body is immersed and conveyed in the liquid through the wet wipe liquid adding conveying roller, so that the wet wipe body is completely immersed in the liquid to uniformly absorb an appropriate amount of liquid to avoid the problem of the surface of the wet wipe body being torn or thinned by the brush. However, there is a situation of liquid adding waste in the above device.

[0028] (1) After the liquid adding method of the present device is changed, the non-woven fabric or wet toilet paper is inserted between the upper and lower rows of cloth picking rollers. There is a certain distance between the upper and lower rows of cloth picking rollers, which is convenient for threading the cloth. The liquid adding pipe is located on the side of the upper row of cloth picking rollers, and the liquid adding angle can be adjusted. The liquid adding range of the liquid adding pipe is adjustable and can be adjusted to an appropriate liquid adding length according to the cloth width, so that the liquid is all added to the non-woven fabric or wet toilet paper. In addition, since the cloth picking rollers are not fixed but can rotate, the non-woven fabric or wet toilet paper can drive the cloth picking rollers to rotate during the transportation process, and the liquid adding holes of the liquid adding pipe do not directly contact the non-woven fabric or wet toilet paper, greatly reducing the resistance during the material transportation process.

[0029] Embodiment 1

[0030] As shown Figures 1-6 in the figure: A non-contact wet wipe liquid adding device includes a frame 1, on which a cloth threading assembly is installed. The cloth threading assembly includes an upper cloth lifting roller group and a lower cloth lifting roller group arranged side by side. Both the upper cloth lifting roller group and the lower cloth lifting roller group are rotatably installed on the frame. On the frame, a wet wipe liquid adding assembly 5 is installed at a position corresponding to one side of the upper row of cloth lifting roller groups. The wet wipe liquid adding assembly 5 includes a liquid adding pipe movably installed on the frame. A plurality of liquid outlet holes 19 are arranged along the length direction on the outer side wall of the liquid adding pipe. The liquid adding angle and width of the liquid adding pipe can be adjusted. The liquid inlet end of the liquid adding pipe is connected to a liquid supply device. Specifically, the adjustment methods of the liquid adding angle and width of the liquid adding pipe are as follows: A liquid adding plate 17 is installed on the frame at the liquid adding position. The liquid adding pipe is rotatably installed on the liquid adding plate. A locking hole position 18 is opened at a position corresponding to the upper part of the liquid adding pipe on the liquid adding plate. A pressing member is installed on the locking hole position. The pressing member is in threaded cooperation with the locking hole position. After the pressing member is tightened, the bottom of the pressing member holds against the outer side wall of the liquid adding pipe to fix the position of the liquid adding pipe. The liquid adding plate installed at the liquid adding position, combined with the pressing member and the locking hole position, can achieve stable fixation of the liquid adding pipe. This design not only ensures the stability of the liquid adding pipe during the liquid adding process, but also facilitates the installation and disassembly of the liquid adding pipe, improving the maintenance convenience of the equipment. One end of the outer side of the liquid adding pipe is open. There is a threaded hole 21 at a position corresponding to the area where the liquid outlet holes are arranged at one end of the outer side of the liquid adding pipe. A width adjusting thimble 20 is installed in the threaded hole 21. The liquid outlet width is changed by changing the screwing depth of the width adjusting thimble 20. This design enables the liquid outlet width of the liquid adding pipe to be adjusted according to needs. This flexibility enables the device to adapt to the liquid adding requirements of wet wipes with different widths, improving the versatility and adaptability of the equipment.

[0031] A plurality of liquid adding pipes are arranged side by side, and each liquid adding pipe is equipped with an independent liquid supply sub-pipeline, a flow meter, and a speed regulating valve. Among the wet wipe liquid adding assemblies, the preferred solution of using a plurality of liquid adding pipes arranged side by side, with each liquid adding pipe equipped with an independent liquid supply sub-pipeline, a flow meter, and a speed regulating valve, brings significant beneficial effects: (1) Improve liquid adding efficiency: Multiple liquid adding pipes work simultaneously, which can significantly accelerate the liquid adding speed of wet wipes and improve the production efficiency of the entire production line. This advantage is particularly obvious on large-scale and high-speed wet wipe production lines. (2) Enhance liquid adding uniformity: Each liquid adding pipe is equipped with an independent liquid supply sub-pipeline, a flow meter, and a speed regulating valve, which can independently control the liquid adding amount, angle, and width of each liquid adding pipe. This ensures that the wet wipes can receive liquid evenly during the transmission process, avoiding quality problems of wet wipes caused by uneven liquid adding.

[0032] Among them, the cloth-lifting rollers in the upper cloth-lifting roller group and the lower cloth-lifting roller group are arranged staggeredly in the horizontal direction. The material 2 (wet wipes and wet toilet paper) is interspersed between the upper cloth-lifting roller group 4 and the lower cloth-lifting roller group 3. One end of the inner side of the cloth-lifting roller is rotatably installed on the machine frame through a rotating shaft. This design can ensure that the wet wipes are more stable during the transmission process, reduce the problem of uneven liquid addition caused by the offset or sliding of the wet wipes, and thus improve the production quality of the wet wipes.

[0033] A liquid collection mechanism is installed on the machine frame 1 at a position directly below the cloth-passing assembly and the liquid addition assembly. The liquid collection mechanism includes a liquid collection tray. The upper end of the liquid collection tray is open and is installed at a position below the cloth-passing assembly and the liquid addition assembly. The liquid outlet end of the liquid collection tray is connected to a liquid collecting hopper. Through the combination of the liquid collection tray 7 and the liquid collecting hopper 8, it is possible to effectively recover the excess liquid that may drip or overflow during the liquid addition process. This not only reduces the waste of liquid but also reduces the humidity of the production environment, which is beneficial to keeping the production line clean and dry.

[0034] The liquid supply device includes a liquid supply hose 16 and a liquid supply main pipe 9. A plurality of liquid supply branch pipes 10 are installed on the liquid supply main pipe. The liquid supply branch pipes are connected to the liquid addition pipes 15 through the liquid supply hoses 16. A flow meter 12 and a speed regulating valve 11 are installed on the liquid supply branch pipes. Through the combination of the liquid supply hose, the liquid supply main pipe, and a plurality of liquid supply branch pipes, and in cooperation with the installation of the flow meter and the speed regulating valve, it is possible to achieve precise control of the liquid addition amount. This design makes the liquid addition process more flexible, and the liquid addition amount can be adjusted according to the requirements of different wet wipe products, improving the flexibility and adaptability of production.

[0035] A protective cover plate 6 is installed on the machine frame 1 at a position above the cloth-passing assembly and the liquid addition assembly. One end of the inner side of the protective cover plate 6 is hingedly installed on the machine frame. It can effectively prevent the operator from coming into direct contact with the high-speed rotating components during the operation process, thereby reducing the risk of accidental injury. One end of the inner side of the protective cover plate is hingedly installed on the machine frame, which is convenient for the operator to open or close when needed, ensuring both the safety and convenience of the operation.

[0036] A feeding platform 13 is installed on the machine frame 1 at a position below the lower cloth-lifting roller group. An unloading platform 14 is installed on the machine frame at the discharging position corresponding to the upper cloth-lifting roller group, and the unloading platform 14 is flush with the upper cloth-lifting roller. The feeding platform is installed below the lower cloth-lifting roller group, which can conveniently feed the wet wipe raw materials to be processed into the production line, reducing the cumbersome and time-consuming manual handling. The unloading platform is installed at the discharging position of the upper cloth-lifting roller group and is flush with the upper cloth-lifting roller, which can ensure that the processed wet wipes are output smoothly and orderly, avoiding the chaos and accumulation of wet wipes during the output process.
