Description
Technical Field
[0001] This utility model relates to the field of impregnation and rolling mill technology, specifically to a nano-coating impregnation and rolling mill for wear-resistant and waterproof Oxford cloth. Background Technology
[0002] Oxford cloth is widely used in bags, outdoor equipment, tents and functional clothing due to its unique weave structure and excellent physical properties. According to announcement number CN210394831U, a new type of textile impregnation machine is disclosed. This technology discloses a technical solution including "a base plate, a U-shaped frame above the base plate, support plates fixedly connected to the bottom of the left and right side walls of the U-shaped frame, the bottom of the support plates fixedly connected to the top of the base plate, support frames installed on the top of the inner cavity of the U-shaped frame and the top of the base plate, a rotating shaft movably connected to the front wall of the support frame via a bearing, a tubular fabric sleeved on the upper rotating shaft, a take-up drum sleeved on the lower rotating shaft, one end of the tubular fabric connected to the take-up drum, movable plates respectively arranged near the left and right sides of the lower part of the tubular fabric, a crossbar arranged between the two movable plates, and through holes matching the crossbar opened on the side walls of the two movable plates, with the left and right ends of the crossbar passing through the through holes and fixedly connected to the inner wall of the U-shaped frame". This technology has the technical effects of "high impregnation efficiency and wide applicability". In the existing production process of Oxford cloth nano-coating, there is a common phenomenon on the production line where pollutants such as environmental dust or fiber debris carried by the fabric itself adhere to the surface of the fabric base. If these foreign objects are not effectively removed before impregnation and coating, they will enter the nano-functional slurry in the impregnation tank along with the fabric. This causes the pollutants to be encapsulated inside the coating or remain at the interface between the coating and the fabric base, forming microscopic physical defects, thereby affecting the continuity and adhesion of the coating. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides a nano-coating impregnation machine for wear-resistant and waterproof Oxford cloth. By pre-processing the online cleaning process, foreign matter on the cloth surface is effectively removed before direct constant-temperature impregnation and precision rolling, thus avoiding contamination of the slurry by impurities from the source. Furthermore, by stabilizing the impregnation conditions, the bonding quality, uniformity, and reliability of the nano-coating on the cloth substrate are significantly improved, as well as the wear-resistant and waterproof performance of the final product.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a nano-coating impregnation machine for abrasion-resistant and waterproof Oxford cloth, comprising an impregnation tank, wherein an impregnation mechanism is provided on the impregnation tank for impregnating the cloth, and the impregnation mechanism is used to impregnate the cloth. The main component includes side frames fixed at both ends of the impregnation tank. A guide roller is rotatably mounted between the front ends of the two side frames, and a cleaning roller is rotatably mounted between the rear ends of the two side frames. The cleaning roller has several circumferentially arranged air holes, and the adjacent air holes are staggered. Impregnation rollers are provided on both the front and rear sides inside the impregnation tank, and the left and right ends of the impregnation rollers are rotatably mounted to the inner wall of the impregnation tank. A roller is provided in the middle of the impregnation tank and located above the impregnation rollers. The left and right ends of the roller are rotatably mounted to the inner wall of the impregnation tank. A power component is provided on the side frames for driving the guide roller and the cleaning roller to rotate synchronously. The tensioning component is mounted on the main component and is used to maintain constant tension during the fabric's movement.
[0005] Preferably, the tensioning assembly includes support arms pivotally connected to the front and rear sides of the inner wall of the side frame, a tensioning roller rotatably installed between the left and right support arms, brackets fixed at both the front and rear ends of the side frame, threaded rods installed on the brackets, and tension springs installed between the threaded rods and the support arms.
[0006] Preferably, the main component further includes a rotary joint rotatably mounted at one end of the cleaning roller, and the rotary joint is connected to the vacuuming device via a hose.
[0007] Preferably, the main component further includes a heating tube installed inside the impregnation tank, and the heating tube is located below the impregnation roller.
[0008] Preferably, the power assembly includes a gearbox mounted on the upper end of the side frame, and the two output ends of the gearbox are fixed to the guide roller and the cleaning roller respectively. A motor is mounted on the outer wall of the side frame, and the output end of the motor is fixed to the input end of the gearbox.
[0009] Preferably, the outer wall of the threaded rod is threaded to the inner wall of the bracket and is used to adjust the preload of the tension spring.
[0010] Beneficial effects This invention provides a nano-coating impregnation machine for abrasion-resistant and waterproof Oxford cloth. Compared with the prior art, it has the following advantages: 1. The fabric first passes through a cleaning roller. The circumferentially arranged and staggered pores on the roller's surface create a more comprehensive negative pressure coverage area during rotation, effectively adsorbing dust and lint from the upper and lower surfaces of the fabric, completing online cleaning before coating. The cleaned fabric then enters the impregnation tank, passing through impregnation rollers positioned at the front and rear to ensure the fabric is fully and evenly impregnated with the nano-functional slurry. Simultaneously, a roller above the impregnation rollers applies uniform and controllable pressure to the wet fabric, precisely squeezing out excess slurry, making the coating initially dense and controlling the liquid retention rate. The impregnated fabric is then smoothly discharged from the guide roller. By placing the cleaning process beforehand and directly connecting it to the impregnation section, the beneficial effect is that foreign objects on the fabric surface can be removed in time before impurities contaminate the slurry, thereby significantly improving the bonding quality, uniformity, and reliability of the abrasion resistance and waterproof performance of the final product.
[0011] 2. The support arm pivotally connected to the side frame can swing around the hinge point, and the tension roller installed between the two support arms floats accordingly and is in close contact with the back of the fabric. When the tension fluctuates due to the uneven tightness of the roll or slight changes in speed during the fabric's movement, the tension roller is driven by the fabric and compresses or releases the tension spring through the support arm, instantly generating a reverse force to buffer and offset the tension change, thereby maintaining the dynamic constant tension of the fabric in the padding section.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0015] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a nano-coating padding machine for wear-resistant and waterproof Oxford cloth, including an impregnation tank 1, an impregnation and padding mechanism 2 for impregnating the cloth, and the impregnation and padding mechanism 2 for the cloth: The main component 21 includes side frames 211 fixed at the left and right ends of the impregnation tank 1. A guide roller 212 is rotatably installed between the front ends of the two side frames 211, and a cleaning roller 213 is rotatably installed between the rear ends of the two side frames 211. The cleaning roller 213 has several circumferentially arranged air holes 214, and adjacent air holes 214 are staggered. Impregnation rollers 216 are provided on both the front and rear sides inside the impregnation tank 1, and the left and right ends of the impregnation rollers 216 are rotatably installed with the inner wall of the impregnation tank 1, respectively. A roller 217 is provided in the middle inside the impregnation tank 1 and is located above the impregnation rollers 216. The left and right ends of the roller 217 are rotatably installed with the inner wall of the impregnation tank 1, respectively. A power component 219 is provided on the side frame 211 and is used to drive the guide roller 212 and the cleaning roller 213 to rotate synchronously. Tensioning component 22 is mounted on main component 21 and is used to maintain constant tension during fabric movement.
[0016] In this embodiment, the fabric first passes through a cleaning roller 213. The circumferentially arranged and staggered pores 214 on the surface of the cleaning roller can form a more comprehensive negative pressure coverage area when rotating, effectively adsorbing dust and lint-like impurities on the upper and lower surfaces of the fabric, completing online cleaning before coating. The cleaned fabric then enters the impregnation tank 1, passing through the impregnation rollers 216 arranged in front and behind, ensuring that the fabric is fully and evenly impregnated with the nano-functional slurry. At the same time, the roller 217 located above the impregnation rollers applies uniform and controllable pressure to the wet fabric, precisely squeezing out excess slurry, making the coating initially dense and controlling the liquid content. The impregnated fabric is finally smoothly discharged from the guide roller 212. By placing the cleaning process in advance and directly connecting it with the impregnation section, the beneficial effect is that foreign objects on the fabric surface can be removed in time before impurities contaminate the slurry, thereby significantly improving the bonding quality, uniformity, and reliability of the abrasion resistance and waterproof performance of the final product.
[0017] Specifically, the tensioning assembly 22 includes support arms 221 pivotally connected to the front and rear sides of the inner wall of the side frame 211, a tensioning roller 222 rotatably mounted between the support arms 221 at the left and right ends, brackets 223 fixed at both the front and rear ends of the side frame 211, threaded rods 224 mounted on the brackets 223, and tension springs 225 mounted between the threaded rods 224 and the support arms 221.
[0018] In this embodiment, the support arm 221 pivotally connected to the side frame 211 can swing around the hinge point, and the tension roller 222 installed between the two support arms 221 floats accordingly and is in close contact with the back of the fabric. When the fabric moves and the tension fluctuates due to the uneven tightness of the roll or slight changes in speed, the tension roller 222 is driven by the fabric and compresses or releases the tension spring 225 through the support arm 221, thereby generating a reverse force to buffer and offset the tension change, thereby maintaining the dynamic constant tension of the fabric in the padding section.
[0019] Specifically, the main component 21 also includes a rotary joint 215 rotatably mounted on one end of the cleaning roller 213, and the rotary joint 215 is connected to the vacuuming equipment via a hose.
[0020] In this embodiment, when the cleaning roller 213 rotates, the inner channel of the rotary joint 215 rotates synchronously with the roller body to transmit negative pressure, while the outer interface remains stationary and is connected to the hose of the external vacuuming equipment, thereby delivering continuous and stable negative pressure to the air holes 214 on the surface of the cleaning roller 213 to achieve continuous and efficient dust removal of the fabric in motion.
[0021] Specifically, the main component 21 also includes a heating tube 218 installed inside the impregnation tank 1, and the heating tube 218 is located below the impregnation roller 216.
[0022] In this embodiment, when the heating tube 218 is working, the heat it generates forms a stable thermal cycle in the impregnation tank 1, ensuring that the slurry that the fabric comes into contact with is always within the optimal temperature range required by the process when it is impregnated by the impregnation roller 216.
[0023] Specifically, the power assembly 219 includes a gearbox 2191 mounted on the upper end of the side frame 211, and the two output ends of the gearbox 2191 are fixed to the guide roller 212 and the cleaning roller 213 respectively. A motor 2192 is mounted on the outer wall of the side frame 211, and the output end of the motor 2192 is fixed to the input end of the gearbox 2191.
[0024] In this embodiment, the rotational power of the motor 2192 is precisely distributed and speed-changed by the transmission mechanism inside the gearbox 2191, and then its two output ends synchronously drive the cleaning roller 213 and the guide roller 212 to rotate in the same direction or at a set speed ratio.
[0025] Specifically, the outer wall of the threaded rod 224 is threaded to the inner wall of the bracket 223 and is used to adjust the preload of the tension spring 225.
[0026] In this embodiment, when the threaded rod 224 is rotated, the threaded rod 224 generates a precise axial displacement through the threaded engagement between its outer wall and the inner wall of the bracket 223; this displacement directly changes the relative distance between the end of the threaded rod 224 and the support arm 221, thereby applying compression or tension to the tension spring 225 connected between the two, and realizing the adjustment of its initial preload.
[0027] The working principle and usage process of this utility model are as follows: First, the fabric passes through the cleaning roller 213, whose surface has circumferentially arranged and staggered air holes 214 that can form a more comprehensive negative pressure coverage area when rotating. At the same time, the motor 2192 in the power assembly 219 starts, and its rotational power is precisely distributed and speed-changed by the transmission mechanism inside the gearbox 2191, and its two output ends synchronously drive the cleaning roller 213 and the guide roller 212 to rotate in the same direction. When the cleaning roller 213 rotates, the inner channel of the rotary joint 215 installed at one end rotates synchronously with the roller body to transmit negative pressure, while the outer interface remains stationary and is connected to the hose of the external vacuuming equipment, thereby delivering continuous and stable negative pressure to the air holes 214 on the surface of the cleaning roller 213, realizing continuous and efficient dust removal of the fabric in motion, and completing online cleaning before coating. The cleaned fabric is then placed into the impregnation tank 1. During this process, the tensioning assembly 22 continues to work: the support arms 221, which are pivotally connected to the front and rear sides of the inner wall of the side frame 211, can swing around the hinge point. The tensioning roller 222, installed between the two support arms 221, floats accordingly and is in close contact with the back of the fabric. When the fabric moves and the tension fluctuates due to the uneven tightness of the roll or slight changes in speed, the tensioning roller 222 is driven by the fabric and compresses or releases the tension spring 225 through the support arm 221, instantly generating a reverse force to buffer and offset the tension change. Among them, by rotating the threaded rod 224, the threaded engagement between its outer wall and the inner wall of the support 223 generates a precise axial displacement, which can change the relative distance between the end of the threaded rod 224 and the support arm 221, thereby adjusting the initial preload of the tension spring 225, and ultimately maintaining the dynamic constant tension of the fabric in the impregnation section. Under constant tension, the fabric passes through the impregnation rollers 216 arranged in front and behind in the impregnation tank 1. At this time, the heating pipe 218 installed inside the impregnation tank 1 and located below the impregnation rollers 216 works, and the heat generated by it forms a stable thermal cycle in the impregnation tank, ensuring that the nano-functional slurry in contact with the fabric is always in the optimal temperature range required by the process, so that the fabric is fully and uniformly impregnated with the slurry. Subsequently, the roller 217 located above the impregnation rollers applies uniform and controllable pressure to the wet fabric, precisely squeezing out excess slurry, making the coating initially dense and controlling the liquid carry-over rate. Finally, the impregnated fabric is smoothly discharged from the guide roller 212, completing the entire nano-coating impregnation process.
