Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile processing technology, and in particular to a uniform impregnation tank structure for flame retardant treatment of fabrics. Background Technology
[0002] Flame retardant treatment of fabrics is a chemical process that slows down combustion and inhibits the spread of flames when the fabric comes into contact with flames and high temperatures. It also allows the fabric to self-extinguish quickly after being removed from the fire source. Furthermore, it reduces toxic fumes and molten drips, thereby lowering the risk of fire. It is widely used in fire-resistant applications such as fire suits, curtains, and automotive seat fabrics. Uniform impregnation tanks are core equipment in industries such as textiles, used to ensure that flexible materials such as fabrics and textiles are evenly contacted and impregnated with treatment solutions such as dyes and flame retardants. Through reasonable structural design, guide roller layout, and parameter control, it ensures that the material is evenly impregnated with liquid without any leakage. Combined with precise control of the liquid volume in subsequent processes, it ensures stable functional finishing effects and is mostly used in continuous production lines.
[0003] In the existing technology, some fabric flame retardant impregnation tank devices are mainly made of corrosion-resistant stainless steel tanks, equipped with guide rollers, tension control rollers, stirring devices, liquid level and temperature control systems and squeezing rollers. A slag discharge port is set at the bottom. During operation, the fabric is smoothly put into the tank through the tension rollers and immersed in the flame retardant along with the guide rollers. Stirring ensures that the agent penetrates the fibers evenly, the liquid level and temperature system ensures the effect, and finally the squeezing roller removes the excess agent to achieve uniform flame retardant treatment.
[0004] In the existing technology, some fabric flame retardant impregnation tank devices lack a dynamic adjustment structure for the contact angle of the feeding roller and the winding path. Most of them are fixed paths and simple tension designs, which are difficult to adapt to the fluctuation of fabric tension. This can easily lead to the fabric being too loose and wrinkling or too tight and breaking, resulting in uneven adsorption of flame retardant and reducing the finished product qualification rate. Therefore, a uniform impregnation tank structure for fabric flame retardant treatment is proposed to solve the above problems. Utility Model Content

After being deeply purified by the filter element, it is transported back to the flame retardant tank by the circulating pump. This solves the problems of insufficient flame retardant penetration, serious waste of agent, and reduced impregnation efficiency due to unsuitable temperature. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figures 1 to 3This utility model provides an embodiment of a uniform impregnation tank structure for flame-retardant treatment of fabric, including a base plate 1. The base plate 1 is the basic load-bearing component of the entire impregnation structure, providing a stable mounting surface and support for all components above. A fixed support plate 2 is fixedly connected to the top of the base plate 1 to fix the working chamber 3 and prevent the working chamber 3 from shaking during operation. The working chamber 3 is fixedly connected to the top of the two fixed support plates 2. The working chamber 3 is the core working space for flame-retardant impregnation treatment of fabric. An adjustment mechanism 4 is fixedly connected to the outside of the working chamber 3. The adjustment mechanism 4 is used to dynamically correct the tension of the fabric during the conveying and impregnation process to avoid uneven impregnation caused by the fabric being too loose or too tight. An impregnation mechanism 5 is fixedly connected to the top of the base plate 1. The impregnation mechanism 5 is responsible for providing assistance for the penetration of flame retardant. The flame retardant purification circulation and adjustment mechanism 4 includes a connecting support plate 41, which is the mounting base of the adjustment mechanism 4. The external side of the connecting support plate 41 is fixedly connected to the right side of the working chamber 3. A connecting component 42 is fixedly connected to the rear side of the external side of the connecting support plate 41. The connecting component 42 is rotatably connected to the cylinder 43, allowing the cylinder 43 to make adaptive angle adjustments during driving. The external side of the connecting component 42 is fixedly connected to the cylinder 43, which is the power source of the adjustment mechanism 4. A rotating shaft 44 is fixedly connected to the driving end of the cylinder 43. The rotating shaft 44 connects the cylinder 43 and the fixed block 45, which plays a transition role in force transmission and direction conversion. The external side of the rotating shaft 44 is fixedly connected to the fixed block 45, which synchronously transmits the movement of the rotating shaft 44 to the conversion plates 46 on both sides.
[0035] Both sides of the fixed block 45 are fixedly connected to conversion plates 46, which are intermediate connecting structures. An L-shaped rotating connecting block 47 is rotatably connected to the adjacent side of the two conversion plates 46. The L-shaped rotating connecting block 47, through this rotating connection structure, receives the force from the conversion plates 46 and changes the direction of the force, converting linear motion into arc-shaped trajectory motion. An arc-shaped rotating block 48 is fixedly connected to the outer right side of the L-shaped rotating connecting block 47. Driven by the L-shaped rotating connecting block 47, the arc-shaped rotating block 48 swings along a preset arc-shaped path. A rotating assembly 49 is fixedly connected to the side. The rotating assembly 49 is the execution end of the adjustment mechanism 4 and is directly associated with the feed roller 6. By changing the position of the feed roller 6, the fabric tension can be adjusted. The connecting assembly 42 includes a rotating square plate 421, which provides installation space for the rotating block 422. The two rotating square plates 421 are fixedly connected to the front side of the connecting support plate 41. The rotating block 422 is rotatably connected inside the two rotating square plates 421. The rotating block 422 rotates between the two rotating square plates (421) and drives the cylinder 43 to rotate flexibly.
[0036] The rotating assembly 49 includes a guide slider 491, which is a motion guide structure of the rotating assembly 49 and restricts the movement trajectory of the adjusting roller 492. The guide slider 491 is externally fixedly connected to the outer right side of the arc-shaped rotating block 48. The adjusting roller 492 is fixedly connected to the outer right side of the guide slider 491. The adjusting roller 492 is in direct contact with the fabric and changes the winding angle and path length of the fabric by changing its position, thereby adjusting the fabric tension. The guide slider 491 is externally rotatably connected to the inside of the working chamber 3. The feed roller 6 is fixedly connected to the adjacent side of the two adjusting rollers 492. The feed roller 6 provides traction force to the fabric by rotating itself, driving the fabric from the unwinding machine into the working chamber 3 and through the impregnation tank 9. At the same time, with the cooperation of the adjusting roller 492, the fabric tension is maintained stably.
[0037] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 The impregnation mechanism 5 includes an ultrasonic generator 51, which is the power source for enhancing the penetration of flame retardant and generates high-frequency ultrasonic signals. The bottom of the ultrasonic generator 51 is fixedly connected to the top of the base plate 1. An ultrasonic transmission tube 52 is fixedly connected to the outer left side of the ultrasonic generator 51. The ultrasonic transmission tube 52 is a signal transmission channel that stably transmits the high-frequency signals generated by the ultrasonic generator 51 to the transducer 53. The other ends of the multiple ultrasonic transmission tubes 52 are fixedly connected to the transducer 53. The transducer 53 can convert the high-frequency signals transmitted by the ultrasonic transmission tubes 52 into mechanical vibrations, which act on the flame retardant in the impregnation tank 9. The flame retardant is subjected to micro-vibrations, which accelerates its penetration into the fabric fibers and improves the uniformity of impregnation. A circulation pump 54 is fixedly connected to the top of the base plate 1. The circulation pump 54 extracts the purified flame retardant and transports it back to the flame retardant tank 10 to realize the recycling of the flame retardant. A purification inlet 55 is fixedly connected to the input end of the circulation pump 54. The purification inlet 55 is the entrance for the flame retardant containing impurities to enter the purification system. It is also the channel for the flame retardant to undergo multi-stage filtration. A guide pipe 56 is fixedly connected to the other end of the purification inlet 55 to buffer and stabilize the flow, so as to prevent the flame retardant containing impurities from flowing too fast and impacting the filter components.
[0038] A flow stabilizing layer 57 is fixedly connected to the left side of the purification inlet 55, which slows down the flow rate of the flame retardant through its own structure. A trapping layer 58 is fixedly connected to the inside of the purification inlet 55. The trapping layer (58) is a primary filter component used to intercept fibers and dust falling from the fabric. A filter element 59 is fixedly connected to the right side of the purification inlet 55. The filter element 59 is a deep filter component that can intercept fine impurities that are not filtered out by the trapping layer 58, further improving the purity of the agent. The external rotating connection of 55 is a quick-opening inspection cover 510. The quick-opening inspection cover 510 makes it easy for operators to open the purification water inlet 55 to clean and replace the flow stabilizing layer 57, the interception layer 58 and the filter element 59. The quick-opening inspection cover 510 is externally fixedly connected to a cover sealing gasket 511. The cover sealing gasket 511 is attached to the contact surface between the quick-opening inspection cover 510 and the purification water inlet 55, which plays a sealing role and prevents the flame retardant from leaking from the gap of the quick-opening inspection cover 510 during the purification process.
[0039] A heater 7 is fixedly connected to the top left side of the base plate 1. The heater 7 generates heat and transfers it to the heating wire 8. The heating wire 8 is fixedly connected to the outside right side of the heater 7. The heating wire 8 acts directly on the impregnation tank 9, evenly transferring the heat generated by the heater 7 to the flame retardant to maintain its activity. The impregnation tank 9 is fixedly connected inside the working chamber 3. The impregnation tank 9 is the core area where the fabric contacts the flame retardant. A drain pipe 14 is fixedly connected to the outside of the impregnation tank 9. The drain pipe 14 is the discharge channel for the flame retardant containing impurities, guiding the flame retardant containing fiber impurities in the impregnation tank 9 to the guide pipe 56 after use. A flame retardant tank 10 is fixedly connected to the top right side of plate 1. A water pump 12 is fixedly connected to the top of the flame retardant tank 10. The water pump 12 is the power source for replenishing the flame retardant. It draws clean flame retardant from the flame retardant tank 10 and transports it back to the impregnation tank 9. An inlet pipe 11 is fixedly connected to the input end of the water pump 12. The inlet pipe 11 connects the water pump 12 and the flame retardant tank 10 and is the extraction channel for the flame retardant. An outlet pipe 13 is fixedly connected to the output end of the water pump 12. The outlet pipe 13 connects the water pump 12 and the impregnation tank 9 and transports the clean flame retardant drawn by the water pump 12 into the impregnation tank 9, completing the flame retardant replenishment cycle.
[0040] Working principle: After the fabric is drawn out from the unwinding machine, it is pulled into the working process by the feed roller 6. First, it enters the impregnation tank 9. The ultrasonic waves generated by the ultrasonic generator 51 are transmitted through the ultrasonic transmission tube 52 and converted into high-frequency vibrations by the transducer 53, which promotes the flame retardant to penetrate into the fabric better. At the same time, the heater 7 heats the heating wire 8 to heat the impregnation tank 9 and maintain a suitable temperature to assist impregnation. When the fabric has abnormal tension due to excessive looseness or tightness due to winding, the adjustment mechanism 4 is activated. The cylinder 43 extends and retracts, driving the conversion plate 46 to move through the rotating shaft 44 and the fixed block 45. Since the conversion plate 46 is rotatably connected to the L-shaped rotating connecting block 47, the L-shaped rotating connecting block 47 is linked with the arc-shaped rotating block 48 to rotate in an arc shape in the working chamber 3, which in turn drives the guide slider 491 of the rotating component 49 to slide, changing the position of the adjustment roller 492, adjusting the winding angle and path of the fabric, and correcting the tension.
[0041] After impregnation, the flame retardant containing impurities flows out from the drain pipe 14 of the impregnation tank 9, is stabilized by the guide pipe 56, and enters the purification inlet 55 at a suitable flow rate. It is first buffered by the flow stabilizing layer 57, then initially intercepted by the interception layer 58, and finally deeply filtered by the filter element 59. The purified flame retardant is pumped back to the flame retardant tank 10 by the circulation pump 54, and the water pump 12 outputs the flame retardant from the liquid outlet pipe 13 back to the impregnation tank 9 to form a cycle, ensuring that the flame retardant continuously and effectively impregnates the fabric. All components work together to achieve efficient and stable flame retardant treatment of the fabric.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
