Description

Technical Field

[0001] This utility model belongs to the field of textile fabric finishing technology, specifically relating to a device suitable for functional finishing of cashmere fabrics. Background Technology

[0002] Cashmere fiber, renowned for its softness, lightness, and warmth, is often referred to as the "diamond of fibers" and is commonly used in the production of high-end knitted underwear and apparel. As consumers, especially those purchasing infant and toddler products, increasingly demand safety, health, and functionality from textiles, developing cashmere fabrics with added antibacterial and comfort features has become a significant trend. One environmentally friendly, safe, and effective method for functionalizing cashmere fabrics is applying natural antibacterial agents (such as tea tree oil microcapsules) through a soaking finishing process.

[0003] Utility model patent CN222434835U discloses a device for soaking mosquito-repellent cooling fabric. The device includes a frame, a soaking tank fixed to the frame, and adjustable pressure rollers, squeeze rollers, feeding and winding mechanisms disposed within the soaking tank. Its working principle involves adjusting the depth of fabric immersion in the finishing agent using the pressure rollers, squeezing out excess finishing agent to reduce waste using the squeeze rollers, and achieving continuous fabric processing through the traction and winding mechanisms.

[0004] However, after analysis, the existing technology still has the following drawbacks:

[0005] First, the soaking tub has an open top design. During the soaking process, highly volatile natural antibacterial components (such as plant essential oils) can easily escape into the air, resulting in the loss of expensive finishing agents. Moreover, the open structure allows dust and impurities from the external environment to easily fall into the finishing solution, contaminating the cashmere fabric and finishing agents, which does not meet the requirements for high-cleanliness production.

[0006] Secondly, an external filter is used to filter the finishing agent pumped from the mixing tank before it is conveyed to the soaking tank. With this design, lint, impurities, etc. generated during circulation inside the soaking tank cannot be filtered and removed in real time. They will gradually accumulate in the soaking solution and may re-adhere to the fabric, affecting the fabric quality and finishing effect. Utility Model Content

[0007] To address the aforementioned problems, the purpose of this invention is to provide a natural antibacterial cashmere fabric treatment device, aiming to solve issues such as component volatilization and contamination caused by open soaking, inability to guarantee the purity of the finishing solution, and poor treatment uniformity.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] A device for treating natural antibacterial cashmere fabric includes a soaking tank, a sealing cover, a fabric winding structure, and a filtering structure.

[0010] The fabric winding structure includes a feeding roller and a winding roller respectively disposed on the outer sides of both ends of the soaking tank, and a pressure roller disposed inside the soaking tank;

[0011] The sealing cover has an inlet and an outlet for fabric input and output on both sides, and an input pipe connected to the liquid dispensing cylinder is provided at the upper end of the sealing cover.

[0012] The soaking tank includes a tank body detachably connected to the sealing cover, and a liquid outlet located at the bottom of the tank body;

[0013] The filtration structure includes a recovery pipe connected to the liquid outlet, a filter pipe disposed at the connection between the liquid outlet and the recovery pipe, a configuration box disposed on the outer end of the housing and connected to the recovery pipe, a distribution pipe distributed on the upper end of the inner side wall of the housing and connected to the configuration box, and a pump body.

[0014] As a further preferred embodiment of this utility model, the housing includes an inner layer, a heating layer, and an insulation layer connected in sequence; a heating structure is provided inside the heating layer.

[0015] As a further preferred embodiment of the present invention, the heating structure includes an inlet pipe and an outlet pipe disposed on the box body and communicating with the heating layer, and the inlet pipe and the outlet pipe are connected to a constant temperature circulation box disposed on the outside of the box body.

[0016] As a further preferred embodiment of the present invention, the filter tube includes a tube body, a first connecting ring plate disposed at the end of the tube body and detachably connected to the inner bottom wall of the housing, a sealing tube connected to the outer bottom surface of the housing and sleeved with the tube body, a filter screen body disposed within the tube body of the sealing tube, and a second connecting ring plate disposed at the end of the sealing tube.

[0017] As a further preferred embodiment of the present invention, the recycling pipe includes a main pipe, a connecting pipe disposed at the end of the main pipe away from the configuration box and connected to the sealing pipe, and a third connecting ring plate disposed at the end of the connecting pipe and detachably connected to the second connecting ring plate.

[0018] As a further preferred embodiment of this utility model, a reduced-diameter ring that is inserted into the sealing tube is provided on the inner wall of the end of the connecting tube.

[0019] As a further preferred embodiment of this utility model, a control valve is provided on the connecting pipeline between the configuration box and the liquid distribution pipe.

[0020] As a further preferred embodiment of this utility model, a sealing layer is provided on the inner wall of both the inlet and outlet.

[0021] As a further preferred embodiment of this invention, the sealing cover is provided with a viewing window.

[0022] As a further preferred embodiment of the present invention, the fabric winding structure further includes a group of extrusion rollers respectively disposed on the inner wall of the sealing cover and located between the winding roller and the pressure roller.

[0023] As a further preferred embodiment of the present invention, the fabric winding structure further includes a group of guide rollers respectively disposed on the inner wall of the sealing cover and located between the winding roller and the unwinding roller.

[0024] The beneficial effects of this utility model are:

[0025] This invention creates a relatively closed processing environment through the cooperation of the sealing cover and the box body. This effectively prevents the loss of volatile components in the natural antibacterial finishing agent, ensures the stability of the processing concentration, and prevents external pollutants from falling in, greatly improving the hygiene level of the processing process. It is particularly suitable for the production of cashmere fabrics with high cleanliness requirements.

[0026] This invention, through its filtration structure, forms a built-in, continuously operating filtration loop. It can filter out small fibers, lint, and any particulate impurities that may be introduced from the fabric in real time, maintaining the continuous cleanliness of the finishing solution. Simultaneously, the even distribution of the solution through the distribution pipe provides strong stirring, preventing the sedimentation of active ingredients and ensuring a highly consistent concentration of finishing agent throughout the chamber.

[0027] This invention achieves indirect, uniform heating and precise temperature control of the soaking finishing agent through structural modifications to the chamber and the installation of a heating structure. This ensures that the natural antibacterial finishing agent always operates at its optimal activity temperature, thereby guaranteeing the uniformity and reliability of the antibacterial treatment effect on cashmere fabrics.

[0044] Example 1

[0045] like Figure 1 As shown, this embodiment provides a natural antibacterial cashmere fabric treatment device, including a soaking tank 100, a sealing cover 200, a fabric winding structure, and a filtering structure; all of the above structures are installed on the bracket c.

[0046] In this embodiment, the fabric winding structure may specifically include an unloading roller 310, a guide roller group 320, a pressure roller 330, a compression roller group 340, and a winding roller 350. The unloading roller 310, guide roller group 320, and winding roller 350 adopt a conventional design (refer to the patent document with authorization announcement number CN222434835U). The guide roller group 320 consists of multiple guide rollers to ensure that the fabric has appropriate tension and a smooth direction throughout the entire transmission path. The winding roller 350 is driven by a servo motor or a variable frequency motor, which can precisely control the winding tension and speed. It is worth noting that the pressure roller 330 is installed inside the soaking tank 100 and is immersed in the finishing solution. Its function is to press the fabric a below the liquid surface to ensure sufficient immersion. The position of the pressure roller 330 can be fixed or designed to be height-adjustable to adapt to different immersion depth process requirements. The extrusion roller assembly 340 typically consists of one active roller and one passive elastic pressure roller, installed inside the sealing cover 200, after the discharge port. When the surface finishing agent exits the liquid, it carries a large amount of excess finishing agent. As it passes through the extrusion roller assembly 340, the high-pressure gap between the two rollers forcefully squeezes out this excess liquid, causing it to drip directly back into the soaking tank 100 below.

[0047] In this embodiment, the soaking tank 100 includes a tank body 110 detachably connected to the sealing cover 200, and a liquid outlet 120 located at the bottom of the tank body 110. In addition, the bottom of the tank body 110 should also be provided with an openable and closable drain outlet (not shown in the figure).

[0048] In this embodiment, the sealing cover 200 has an inlet and an outlet on both sides for inputting and outputting fabric a, respectively, and the upper end of the sealing cover 200 has an input pipe 210 connected to the liquid dispensing cylinder b and a viewing window 230. The main frame of the sealing cover 200 can be made of metal, and the viewing window 230 is made of glass or other transparent material and embedded in the frame, allowing operators to clearly observe the fabric's operating status, liquid level, and finishing agent circulation within the chamber without opening the cover. Figure 5 As shown, a sealing layer 220 is provided on the inner wall of the inlet and outlet. This sealing layer 220 is preferably made of silicone. When fabric a passes through it, the flexible silicone layer adheres to the fabric surface, forming an effective seal. This greatly limits the escape channels of gas and vapor, helping to maintain a slightly positive pressure environment inside the chamber and further preventing external air from entering. At the same time, the soft silicone will not scratch the precious cashmere fabric. In addition, the contact edge between the sealing cover 200 and the chamber body 110 is embedded with a corrosion-resistant rubber or silicone sealing strip to ensure a tight seal when closed. The sealing cover 200 can be opened with manual pneumatic support or electric push rod control, facilitating maintenance operations such as material replacement and cleaning.

[0049] In this embodiment, the filtration structure includes a recovery pipe 130 connected to the outlet 120, a filter pipe 140 disposed at the connection between the outlet 120 and the recovery pipe 130, a configuration box 150 disposed on the outer end of the housing 110 and connected to the recovery pipe 130, a distribution pipe 160 distributed on the upper end of the inner side wall of the housing 110 and connected to the configuration box 150, and a pump body 170; a control valve 180 is provided on the connecting pipe between the configuration box 150 and the distribution pipe 160.

[0050] More specifically, such as Figure 2 , Figure 4As shown, the filter tube 140 includes a tube body 1401, a first connecting ring plate 1402 disposed at the end of the tube body 1401 and detachably connected to the inner bottom wall of the housing 110, a sealing tube 1404 connected to the outer bottom surface of the housing 110 and sleeved on the tube body 1401, a filter screen body 1403 disposed within the tube body of the sealing tube 1404, and a second connecting ring plate 1405 disposed at the end of the sealing tube 1404. The tube body 1401 is generally a short, vertical tube, with its upper end passing through the outlet 120 and fixed to the inner bottom wall of the housing 110 by bolts via the first connecting ring plate 1402. The upper end of the sealing tube 1404 is fixedly connected to the outer bottom wall of the housing 110 via a flange structure and sleeved on the outside of the tube body 1401. The lower end of the sealing tube 1404 is flanged outward to form the second connecting ring plate 1405. The filter body 1403 is housed within the sealing tube 1404, which can be a cylindrical stainless steel filter with a mesh count selectable according to processing requirements. It is used to intercept impurities such as lint and fiber debris. This quick-release design means that when cleaning or replacing the filter is required, simply loosen the connection between the second connecting ring plate 1405 and the lower part to remove the entire sealing tube 1404 along with the filter body 1403, making maintenance very convenient.

[0051] More specifically, the recovery pipe 130 includes a main pipe 1301, a connecting pipe 1302 disposed at the end of the main pipe 1301 away from the configuration box 150 and mating with the sealing pipe 1404, and a third connecting ring plate 1303 disposed at the end of the connecting pipe 1302 and detachably connected to the second connecting ring plate 1405. To ensure reliable sealing, a reducing ring 1304 is provided on the inner wall of the end of the connecting pipe 1302 and inserted into the sealing pipe 1404. When the two parts are mated, the reducing ring 1304 will be tightly inserted into the lower port of the sealing pipe 1404, forming an additional sealing barrier to prevent liquid leakage.

[0052] More specifically, the pump body 170 is typically mounted on the main pipe 1301. The preparation tank 150 serves as an intermediate buffer and observation container, and its side wall can be equipped with a level sight glass. The outlet of the preparation tank 150 is connected to the distribution pipe 160 via a pipeline, and a control valve 180 installed on the pipeline is used to regulate the circulation flow rate. The distribution pipe 160 is horizontally fixed to the inner wall of the soaking tank 100 near the top. When the pump body 170 is operating, it pumps the filtered finishing agent from the bottom of the tank to the distribution pipe 160, and then evenly sprays it onto the return liquid surface or directly onto the fabric being processed through small holes or slits on the distribution pipe 160 in the form of a fine rain or a thin stream. This process achieves three benefits: first, continuous filtration to keep the liquid clean; second, strong agitation to prevent the precipitation of active ingredients and ensure uniform concentration; and third, a certain fluid scouring effect on the fabric immersed in the liquid, which helps the finishing agent penetrate more evenly.

[0053] The working process of this device is as follows:

[0054] S1. Open the sealing cap 200 and inject the preset amount of deionized water or basic solvent into the soaking tank 100. Tighten the sealing cap 200. Add the calculated amount of natural antibacterial finishing agent into the tank through the inlet pipe 210 from the solution preparation cylinder b.

[0055] S2. Start the pump body 170 and open the control valve 180 to the appropriate opening degree. The finishing agent begins a closed loop from the bottom of the tank—filter pipe 140—recovery pipe 130—mixing tank 150—distribution pipe 160—within the tank. At this time, the filtration and stirring functions begin to work. Install the cashmere fabric roll on the feed roller 310, guide the head, and pass it sequentially through the feed inlet, guide roller group 320, below the pressure roller 330, the discharge port, and the extrusion roller group 340, finally fixing it on the take-up roller 350.

[0056] S3. The fabric is continuously pulled along at a set speed. Inside a sealed, temperature-controlled chamber, the fabric is thoroughly soaked in a uniform and clean antibacterial finishing agent. The circulating finishing agent continuously washes over the fabric, promoting the adsorption of effective ingredients such as microcapsules. The extrusion roller group 340 efficiently squeezes excess finishing agent carried on the treated fabric back into the chamber.

[0057] S4. Observe the operating status through window 230. The level gauge (which can be installed on the tank 110) monitors the liquid level. During the treatment process, the finishing agent will be consumed normally. Fresh finishing agent can be added intermittently or continuously from the liquid mixing cylinder b through the input pipe 210 to maintain a stable treatment concentration.

[0058] S5. Once a batch of fabric has been processed, open the sealed cover to remove the processed fabric roll. If it is necessary to replace the finishing agent or perform a thorough cleaning, open the drain port at the bottom of the box to drain the waste liquid. Periodically loosen the connection of the filter tube 140 and remove the filter body 1403 for cleaning or replacement to maintain filtration efficiency.

[0059] Example 2

[0060] This embodiment optimizes the structure based on embodiment 1, such as... Figure 3 As shown, the details are as follows:

[0061] The housing 110 includes an inner layer 1101, a heating layer 1102, and an insulation layer 1103 connected in sequence; a heating structure is provided inside the heating layer 1102. The heating structure includes an inlet pipe 410 and an outlet pipe 420 disposed on the housing 110 and communicating with the heating layer 1102. The inlet pipe 410 and the outlet pipe 420 are connected to a constant temperature circulation chamber 430 disposed on the outside of the housing 110.

[0062] The inner 1101 layer comes into direct contact with the natural antibacterial finishing liquid and cashmere fabric. Therefore, it is made of corrosion-resistant, chemically stable and easy-to-clean materials, such as 304 or 316L stainless steel plates. The inner surface can be polished to reduce the adhesion of liquid and dirt.

[0063] The heating layer 1102 is a sealed cavity jacket welded or nested on the outer wall of the inner layer 1101. A heat transfer medium (typically water or heat transfer oil) flows within this jacket. The inlet pipe 410 and outlet pipe 420 are connected to an external constant-temperature circulation chamber 430 via insulated piping. The constant-temperature circulation chamber 430 contains a heater, temperature sensor, and circulation pump, enabling precise control of the output heat transfer medium temperature within a suitable range. The hot medium enters the heating layer 1102 through the inlet pipe 410, flows around the inner layer 1101, and evenly transfers heat to the inner layer 1101 and its internal finishing agent. Then, the slightly cooler medium returns from the outlet pipe 420 to the constant-temperature circulation chamber 430 for reheating, and this cycle repeats. This indirect heating method is gentle and uniform, avoiding localized overheating that could damage the active ingredients of the natural finishing agent and the delicate cashmere fibers.

[0064] The insulation layer 1103 is wrapped around the heating layer 1102, and is typically filled with polyurethane foam or wrapped with high-efficiency insulation materials such as rock wool, and then sealed with a thin metal plate. The insulation layer 1103 can greatly reduce heat loss during the process, improve energy utilization efficiency, and maintain a stable temperature inside the chamber.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
