Description

Technical Field

[0001] This utility model relates to the field of wet wipe production technology, and specifically discloses a fabric processing device for wet wipe production. Background Technology

[0002] As a convenient cleaning and care product, the core of wet wipe production quality lies in the uniform and thorough saturation of the non-woven fabric with the cleaning solution. Currently, the fabric saturation process in wet wipe production mainly relies on impregnation tanks or spray-type devices. Impregnation tanks directly immerse the non-woven fabric in the solution, using static placement or simple guide rollers to achieve saturation; this method is simple in structure and widely used. Spray-type devices, on the other hand, spray the solution onto the fabric surface through nozzles to achieve a wetting effect. These traditional technologies can basically meet the basic wetting requirements of ordinary wet wipes.

[0003] In practical applications, the aforementioned existing technologies have been found to have significant limitations. First, for high-grammage, high-density, or specially structured nonwoven fabrics, traditional static impregnation or surface spraying methods cannot ensure rapid and sufficient penetration of the liquid into the fiber bundles, easily creating impregnation blind spots. This results in uneven distribution of the effective ingredients in the finished wipes, significantly reducing their cleaning and wiping effectiveness. Second, the liquid is prone to component sedimentation or concentration stratification within the impregnation tank. Coupled with the lack of an effective dynamic circulation and uniform mixing mechanism, it is difficult to guarantee the stability of moisture content and efficacy between different batches, and even within the same batch of wipes, affecting product quality consistency. Furthermore, achieving sufficient impregnation often requires extending the fabric's residence time in the liquid or increasing the amount of liquid used, which to some extent restricts production efficiency and increases production costs.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0017] Please see Figure 1-3 A fabric processing device for producing wet wipes includes a frame 1, an impregnation box 2 disposed on the frame 1, and a transmission roller group 3 for driving nonwoven fabric through the impregnation box 2. An ultrasonic transducer 4 and an ultrasonic generator 5 are installed above the impregnation box 2. The ultrasonic transducer 4 is electrically connected to the ultrasonic generator 5, and the radiating end of the ultrasonic transducer 4 extends into the interior of the impregnation box 2. A microporous aeration disc 6 is installed at the bottom of the interior of the immersion tank 2. The microporous aeration disc 6 is connected to an air pump 8 fixed to the outer wall of the immersion tank 2 via an air supply pipe 7. A circulation pipe 9 is connected between the bottom and top of the side wall of the immersion tank 2, and a filter 11 and a circulation pump 10 are installed in sequence on the circulation pipe 9. It also includes a control system 13, which is electrically connected to the ultrasonic generator 5, the air pump 8 and the circulating pump 10 respectively.

[0018] In this embodiment: by setting an ultrasonic transducer 4 driven by an ultrasonic generator 5 above the impregnation tank 2, the cavitation effect generated by the ultrasonic waves in the liquid agent is used to strongly promote the liquid agent to penetrate into the nonwoven fabric fibers, solving the problem of impregnation blind spots in traditional impregnation methods and achieving a deep and uniform impregnation effect. At the same time, a microporous aeration plate 6 supplied with air by an air pump 8 is set at the bottom of the impregnation tank 2. The fine bubble flow generated by the plate can continuously stir the liquid agent in the tank, effectively preventing the precipitation of effective components and concentration stratification, and ensuring the consistency of product quality. In addition, a circulation pump 10 and a filter 11 are set on the circulation pipeline 9 connected between the bottom and top of the side wall of the impregnation tank 2, which can dynamically circulate and filter the liquid agent, maintaining the cleanliness and mixing uniformity of the liquid agent. Finally, the control system 13 coordinates the operation of the ultrasonic generator 5, the air pump 8 (the air pump 8 can be an oil-free silent air compressor or a vortex fan, which is a conventional choice to meet the requirements of cleanrooms) and the circulation pump 10, which together constitute a highly efficient, stable and highly automated impregnation system.

[0019] The circulating pump 10 can be a corrosion-resistant centrifugal pump or a magnetic pump, and the filter 11 can be a bag filter or a cartridge filter. The filter screen precision can be selected according to the characteristics of the liquid, for example, 5 to 50 microns. These are all conventional components for fluid transport and filtration.

[0020] The control system 13, as the core of the device, can be implemented using an industry-standard programmable logic controller (PLC), microcontroller, or embedded system. It receives detection signals from the liquid level sensor 17 through built-in general-purpose digital and analog input / output modules. The liquid level sensor 17 can be an immersion hydrostatic level gauge or an ultrasonic level gauge, which determines the liquid level by detecting the hydrostatic pressure or reflected echo of the liquid; this is a mature and well-known sensing technology. The control system 13 executes control functions such as "activating an alarm when the liquid level is below a set threshold" and "starting and stopping the ultrasonic generator 5, air pump 8, and circulation pump 10 in conjunction with production instructions" according to preset program logic. Specifically, its control logic compares the feedback signal from the liquid level sensor 17 with internally stored set parameters, and then outputs control signals to drive the actions of various actuators (such as circulation pump 10 and air pump 8). The implementation of this closed-loop control logic is a conventional design method for those skilled in the art, and its structure will not be described in detail here.

[0021] As a technical optimization of this utility model, the transmission roller group 3 includes a first guide roller 14 horizontally arranged above the feed inlet of the immersion tank 2, an immersion pressing roller 15 arranged at the bottom of the internal cavity of the immersion tank 2, and a pair of extrusion rollers 16 vertically arranged at the discharge outlet of the immersion tank 2.

[0022] In this embodiment, by setting the first guide roller 14, the immersion roller 15, and the squeeze roller 16, a clear transmission path is set for the nonwoven fabric. The immersion roller 15 ensures that the nonwoven fabric is completely immersed in the liquid, while the squeeze roller 16 squeezes out excess liquid when discharging. This ensures that the path of the nonwoven fabric is stable and fully immersed during the wetting process, and can accurately control the final liquid content of the finished wet wipes, avoiding waste and ensuring a good user experience.

[0023] As a technical optimization of this utility model, a liquid level sensor 17 for monitoring the liquid level is installed on the inner wall of the immersion tank 2, and the liquid level sensor 17 is electrically connected to the control system 13.

[0024] In this embodiment: a liquid level sensor 17 is installed on the inner wall of the immersion tank 2 and its signal is connected to the control system 13, which realizes automatic monitoring and compensation of the immersion liquid level, maintains the stability of the liquid level during the production process, thereby ensuring the continuity of ultrasonic and aeration effects and avoiding uneven immersion caused by liquid level fluctuations.

[0025] As a technical optimization of this utility model, the ultrasonic transducer 4 operates in the frequency range of 20kHz to 40kHz.

[0026] In this embodiment, the operating frequency of the ultrasonic transducer 4 is limited to the preferred range of 20kHz to 40kHz. The ultrasonic cavitation effect is strong and the penetration is moderate within this frequency range, which can ensure excellent wetting effect while avoiding potential damage to the nonwoven fiber structure and ensuring that energy consumption and efficiency are at the best balance point.

[0027] As a technical optimization of this utility model, an outlet 12 is provided below the front end face of the immersion tank 2.

[0028] In this embodiment, an independent liquid outlet 12 is provided below the front end face of the immersion tank 2, which facilitates the rapid emptying of the old liquid agent in the tank during material replacement, cleaning or maintenance, thereby improving the ease of operation and maintenance efficiency of the equipment.

[0029] As a technical optimization of this utility model, the back of the frame 1 is fixedly connected to the mounting plate 19 located directly above the immersion tank 2 by two support rods 18, and the ultrasonic transducer 4 and the ultrasonic generator 5 are both installed on the upper surface of the mounting plate 19.

[0030] In this embodiment, the mounting plate 19 is fixed directly above the immersion tank 2 by the support rod 18, and the ultrasonic transducer 4 and generator 5 are centrally mounted on it, forming a stable and independent mounting structure. This ensures the stability of the ultrasonic core components, effectively reduces vibration interference, facilitates centralized maintenance, and makes the overall structure more compact and reasonable.

[0031] As a technical optimization of this utility model, a solenoid valve 20 is provided at the liquid outlet 12, and the solenoid valve 20 is electrically connected to the control system 13.

[0032] In this embodiment, a solenoid valve 20 is provided at the liquid outlet 12. The solenoid valve 20 is electrically connected to the control system 13 to facilitate the control of the opening and closing of the liquid outlet 12.

[0033] The working principle and usage process of this utility model: The non-woven fabric is pulled by an external winding device. First, the circulation pump 10 is started, so that the liquid in the impregnation tank 2 is continuously drawn out through the circulation pipeline 9, purified by the filter 11, and then flows back to the upper part of the tank, forming a dynamic circulation. At the same time, the control system 13 starts the ultrasonic generator 5 and the ultrasonic transducer 4, so that the radiation end of the transducer 4 emits ultrasonic waves into the liquid, and starts the air pump 8 to supply air to the microporous aeration plate 6 through the air supply pipeline 7, generating uniform and fine bubbles at the bottom of the tank. At this time, Under the traction of the transmission roller group 3, the non-woven fabric first passes through the first guide roller 14 to change direction, and then is guided by the immersion roller 15 to be completely immersed in the liquid that is undergoing ultrasonic cavitation and bubble stirring, so as to achieve full and deep immersion. After immersion, the non-woven fabric continues to move forward and passes through a pair of extrusion rollers 16 to squeeze out excess liquid to control the moisture content. Finally, the processed wet wipe fabric is transported to the next process, while the liquid level sensor 17 monitors the liquid level in real time and feeds the information back to the control system 13 to maintain the stable operation of the whole process.
