Description

Technical Field

[0001] This utility model belongs to the technical field of polyester fabric treatment, and in particular relates to a quaternary ammonium salt impregnation and finishing device for antibacterial treatment of polyester fabric. Background Technology

[0002] Polyester fabric is popular among consumers because of its durability, wrinkle resistance, quick drying and easy washing. Before making clothing from polyester fabric, it needs to be impregnated with antibacterial agents to evenly adhere to the surface or interior of the fabric, thereby inhibiting the growth of bacteria. Padding is an environmentally friendly pretreatment process in the textile printing and dyeing industry, mainly used for the pretreatment of cotton or polyester-cotton knitted fabrics. It replaces the traditional strong alkali and high-temperature process with bio-enzymes, reducing fiber damage and wastewater pollution. Padding with quaternary ammonium salt solutions can disrupt the cell membrane structure of microorganisms due to the cationic properties of quaternary ammonium salts, causing leakage of cell contents and ultimately leading to the disintegration and death of microorganisms, thus achieving antibacterial treatment of the fabric. However, in the process of using traditional quaternary ammonium salt padding finishing equipment for antibacterial treatment of polyester fabrics, the following problems still exist: When impregnating polyester fabric, errors in the feeding device may cause the fabric edges to curl, resulting in insufficient impregnation of the fabric edges during the impregnation process, which affects the overall impregnation effect of the fabric. During impregnation, the polyester fabric needs to be completely submerged in the impregnating material. Since polyester fabric itself has a certain degree of water absorption, it will absorb excess impregnating material. This excess impregnating material cannot be scraped off, resulting in waste of impregnating material. During the impregnation process, the polyester fabric passes through the impregnation material in the impregnation tank to complete the impregnation. Due to the limited space inside the impregnation tank, the movement path of the polyester fabric inside the tank is relatively short, which may result in insufficient impregnation.

[0003] To address these issues, we provide a quaternary ammonium salt impregnation and finishing apparatus for antibacterial treatment of polyester fabric. Utility Model Content

[0004] The purpose of this invention is to provide a quaternary ammonium salt impregnation and finishing device for antibacterial treatment of polyester fabric. By setting up a support roller, a steam box, a flattening component, a fixed platform, a lower roller, and an upper roller, it solves the problems of insufficient impregnation caused by edge curling during polyester fabric impregnation, waste of quaternary ammonium salt solution, and insufficient impregnation caused by a short impregnation path.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a quaternary ammonium salt impregnation and finishing device for antibacterial treatment of polyester fabric, comprising an impregnation tank, a steam tank, a flattening assembly, and a fixed platform; one end of the impregnation tank is fixedly connected to the steam tank, and the other end of the impregnation tank is fixedly connected to the fixed platform with a sloping top surface; both sides of the top of the impregnation tank are fixedly connected to a support plate, and guide rollers are rotatably connected between the two support plates near their ends; the top of the steam tank has a through-hole with steam holes arranged in a rectangular array; the flattening assembly includes a V-shaped pressure plate located above the steam tank, with the opening of the pressure plate facing the impregnation tank; When impregnating polyester fabric, the polyester fabric is introduced from the end of the steam box away from the impregnation box. It first passes through the top of the steam box, where the steam box heats the polyester fabric to soften it. Under the pressing action of the V-shaped pressure plate, the wrinkles and curls on the surface of the polyester fabric are smoothed out. Then, it is guided by the guide rollers near the steam box and enters the impregnation box for impregnation. After impregnation, it is guided by the guide rollers near the fixed table and then discharged. Both sides of the top of the fixed platform are fixedly connected to the second support plate connected to the first support plate. A lower roller connected to the two second support plates is provided above the higher end of the inclined surface of the fixed platform. An upper roller connected to the two second support plates is provided above the lower roller. After being guided by the guide rollers near the fixed platform, the polyester fabric moves between the lower and upper rollers. The lower and upper rollers rotate relative to each other, squeezing the polyester fabric to distribute the impregnating material evenly within it and extruding excess quaternary ammonium salt solution. The extruded quaternary ammonium salt solution flows back into the impregnation tank along the upper inclined surface of the fixed platform.

[0006] Furthermore, a connecting plate is fixedly connected to the top of the pressure plate, and threaded rods are rotatably connected to the top of the steam box near both ends. Both threaded rods are threadedly connected to the connecting plate. Pulleys are fixedly connected to the upper periphery of both threaded rods, and a transmission belt is connected between the two pulleys. A handwheel is fixedly connected to the top of one of the threaded rods. Turning the handwheel causes the two threaded rods to rotate simultaneously under the action of the pulley and belt, moving the connecting plate up and down, which in turn moves the pressure plate up and down to flatten polyester fabrics of different thicknesses.

[0007] Furthermore, the top height of the steam box is the same as the higher end height of the guide roller, and a heating tube is fixedly connected inside the steam box; Add water to the heating chamber, and the heating element will heat the water to produce steam.

[0008] Furthermore, three support rollers arranged in an isosceles triangle are rotatably connected between the two side walls of the immersion tank, and the support roller at the apex position and the two guide rollers are also arranged in an isosceles triangle. After being guided by the guide rollers, the fabric enters the impregnation tank and passes around three support rollers before turning to another guide roller, extending the impregnation path of the polyester fabric.

[0009] Furthermore, a motor is fixedly connected to one of the support plates near both ends on the side away from the guide roller, and the output shaft of the motor is connected to the end of the guide roller near it. When motor one is started, the output shaft of motor one rotates, which drives the guide roller to rotate, guiding the polyester fabric while assisting in the feeding and discharging work.

[0010] Furthermore, a motor is fixedly connected to one of the support plates two on the side away from the lower roll, and the output shaft of the motor two is connected to the end of the lower roll adjacent to it in a transmission connection; Start motor two. The output shaft of motor two rotates, which drives the lower roller to rotate, applying pressure to the polyester fabric while simultaneously unloading the polyester fabric.

[0011] Furthermore, the lower end of the upper inclined surface of the fixed platform is at the same height as the top end of the immersion tank, and a filter screen is fixedly connected between the two support plates near the immersion tank. The top end of the filter screen is lower than the higher end of the guide roller, and the bottom end of the filter screen is attached to the inclined surface of the fixed platform. The squeezed-out quaternary ammonium salt solution must be filtered through a filter screen before flowing back into the immersion tank to prevent foreign matter from contaminating the quaternary ammonium salt solution.

[0012] This utility model has the following beneficial effects: This invention solves the problem of insufficient impregnation caused by edge curling of polyester fabric by setting up a steam box and a flattening component. When feeding polyester fabric, the polyester fabric first passes through the top of the steam box. High-temperature steam rises from the steam hole to heat the polyester fabric and soften it. At the same time, the V-shaped pressure block flattens the polyester fabric to prevent edge curling, thereby improving the impregnation effect.

[0013] This invention solves the problem of wasted impregnation material by setting up a fixed platform, a lower roller, and an upper roller. After impregnation, the polyester fabric moves to the gap between the lower roller and the upper roller. The lower roller and the upper roller rotate relative to each other, squeezing the polyester fabric to make the impregnation material evenly distributed on the polyester fabric while squeezing out the excess impregnation material. The excess quaternary ammonium salt solution squeezed out flows back into the impregnation tank along the upper inclined surface of the fixed platform, thus achieving the purpose of saving quaternary ammonium salt solution.

[0014] This invention solves the problem of short impregnation path for polyester fabric by setting support rollers; after being guided by guide rollers, the fabric enters the impregnation tank and passes around three support rollers in sequence before passing around another guide roller, thus extending the impregnation path of the polyester fabric and making the impregnation of the polyester fabric more thorough.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-4 This utility model is a quaternary ammonium salt impregnation and finishing device for antibacterial treatment of polyester fabric, including an impregnation tank 1, a steam tank 2, a flattening component 3, and a fixed platform 4; one end of the impregnation tank 1 is fixedly connected to the steam tank 2, and the other end of the impregnation tank 1 is fixedly connected to the fixed platform 4 with a sloping top surface; both sides of the top of the impregnation tank 1 are fixedly connected to support plates 101, and guide rollers 102 are rotatably connected between the two support plates 101 near both ends; the top of the steam tank 2 has a through-hole steam hole 202 distributed in a rectangular array; the flattening component 3 includes a V-shaped pressure plate 306 located above the steam tank 2, and the opening of the pressure plate 306 faces the impregnation tank 1; The impregnation tank 1 is filled with a quaternary ammonium salt solution. When impregnating polyester fabric, the polyester fabric is introduced from the end of the steam tank 2 away from the impregnation tank 1. It first passes through the top of the steam tank 2, where high-temperature steam rises from the steam hole 202 to heat the polyester fabric, softening it. Under the pressing action of the V-shaped pressure plate 306, the wrinkles and curls on the surface of the softened polyester fabric are smoothed out. At the same time, the heated polyester fabric absorbs the quaternary ammonium salt solution more easily, improving the impregnation efficiency. Then, the polyester fabric is guided by the guide roller 102 near the steam tank 2 and enters the impregnation tank 1. The polyester fabric is immersed in the quaternary ammonium salt solution for impregnation. After being guided by the guide roller 102 near the fixed table 4, it is discharged.

[0026] Among them, such as Figure 3 , Figure 4 As shown, a connecting plate 305 is fixedly connected to the top of the pressure plate 306. Threaded rods 301 are rotatably connected to the top of the steam box 2 near both ends. Both threaded rods 301 are threadedly connected to the connecting plate 305. Pulleys 302 are fixedly connected to the upper part of the periphery of both threaded rods 301. A transmission belt 303 is connected between the two pulleys 302. A handwheel 304 is fixedly connected to the top of one of the threaded rods 301. Turning the handwheel 304 causes the threaded rod 301 connected to the handwheel 304 to rotate. Under the action of the pulley 302 and the belt, another threaded rod 301 rotates simultaneously. With the rotation of the two threaded rods 301, the connecting plate 305 moves up and down, which in turn drives the pressure plate 306 to move up and down, flattening polyester fabrics of different thicknesses.

[0027] Among them, such as Figure 1-3 As shown, the top height of the steam box 2 is the same as the higher end height of the guide roller 102, and a heating pipe 201 is fixedly connected inside the steam box 2. Water is added to the steam box 2, and the heating tube 201 heats the water to generate steam. The steam heats the polyester fabric through the steam hole 202. Since the top height of the steam box 2 is the same as the higher end height of the guide roller 102, the polyester fabric will not wrinkle when it moves from the top of the steam box 2 to the guide roller 102.

[0028] Among them, such as Figure 2 , Figure 3 As shown, three support rollers 104 arranged in an isosceles triangle are rotatably connected between the two side walls of the immersion tank 1, and the support roller 104 located at the apex position and the two guide rollers 102 are also arranged in an isosceles triangle. After being guided by the guide roller 102 near the steam box 2, the polyester fabric enters the impregnation box 1, passes around the three support rollers 104 in sequence, and then passes around the guide roller 102 near the fixed platform 4. The arrangement of the three support rollers 104 extends the impregnation path of the polyester fabric, making the polyester fabric impregnated more fully, while keeping the polyester fabric straight and preventing wrinkles.

[0029] Among them, such as Figure 1 , Figure 2 As shown, a motor 103 is fixedly connected to one of the support plates 101 on the side away from the guide roller 102 near both ends. The output shaft of the motor 103 is connected to the end of the guide roller 102 near it. Start motor 103. The output shaft of motor 103 rotates, which drives guide roller 102 to rotate, guiding the polyester fabric while assisting in feeding and discharging.

[0030] The working principle of this embodiment is as follows: Water is added to the steam box 2, and the heating tube 201 is started to heat the water. The handwheel 304 is rotated according to the thickness of the polyester fabric, causing the threaded rod 301 connected to the handwheel 304 to rotate. Under the action of the pulley 302 and the belt, another threaded rod 301 rotates simultaneously. With the rotation of the two threaded rods 301, the connecting plate 305 moves up and down, making the distance between the pressure block and the steam box 2 consistent with the thickness of the polyester fabric. Once steam emerges from the steam hole 202, the impregnation process can begin. When impregnating the polyester fabric, the motor 103 is started. The polyester fabric is introduced from the end of the steam box 2 away from the impregnation tank 1, first passing through the top of the steam box 2. High-temperature steam rises from the steam hole 202 to impregnate the polyester fabric. Heating softens the polyester fabric. Under the pressure of the V-shaped pressure plate 306, the wrinkles and curls on the surface of the softened polyester fabric are smoothed out. At the same time, the heated polyester fabric absorbs the quaternary ammonium salt solution more easily, improving the efficiency of the impregnation process. The output shaft of motor 103 rotates, driving the guide roller 102 to rotate, which conveys and guides the polyester fabric. After being guided by the guide roller 102 near the steam box 2, the polyester fabric enters the impregnation box 1, passes around the three support rollers 104 in sequence, and is immersed in the quaternary ammonium salt solution for impregnation. After being guided by the guide roller 102 near the fixed platform 4, it is discharged. The setting of the three support rollers 104 extends the impregnation path of the polyester fabric, making the impregnation of the polyester fabric more thorough, while keeping the polyester fabric straight and preventing wrinkles. Specific Implementation Example 2

[0031] Please see Figure 1 , Figure 2 and Figure 6 Based on the first specific embodiment, the top two sides of the fixed platform 4 are fixedly connected to the second support plate 401 connected to the first support plate 101. The upper end of the inclined surface of the fixed platform 4 is provided with a lower roller 403 rotatably connected to the two second support plates 401. The upper roller 402 rotatably connected to the two second support plates 401 is provided above the lower roller 403. After being guided by the guide roller 102 near the fixed platform 4, the polyester fabric moves between the lower roller 403 and the upper roller 402. The lower roller 403 and the upper roller 402 rotate relative to each other, squeezing the polyester fabric so that the quaternary ammonium salt solution is evenly distributed in the polyester fabric and the excess quaternary ammonium salt solution is squeezed out. The squeezed-out quaternary ammonium salt solution flows back into the dipping tank 1 along the upper inclined surface of the fixed platform 4.

[0032] Among them, such as Figure 1 , Figure 2 As shown, a motor 404 is fixedly connected to one of the support plates 401 on the side away from the lower roll 403, and the output shaft of the motor 404 is connected to the end of the lower roll 403 nearby. Start motor 404. The output shaft of motor 404 rotates, which drives the lower roller 403 to rotate, applying pressure to the polyester fabric while pulling the polyester fabric to discharge.

[0033] Among them, such as Figure 1 , Figure 2 and Figure 6 As shown, the lower end of the upper inclined surface of the fixed platform 4 is at the same height as the top end of the immersion tank 1. A filter screen 405 is fixedly connected between the two support plates 401 near the immersion tank 1. The top end of the filter screen 405 is lower than the higher end of the guide roller 102, and the bottom end of the filter screen 405 is attached to the upper inclined surface of the fixed platform 4. The squeezed-out quaternary ammonium salt solution flows along the upper inclined surface of the fixed platform 4 under the action of gravity, and flows back to the immersion tank 1 after being filtered by the filter screen 405. The filter screen 405 can prevent foreign objects from flowing into the immersion tank 1 along with the quaternary ammonium salt solution and contaminating the quaternary ammonium salt solution.

[0034] The working principle of this embodiment is as follows: Motor 404 is started, and the output shaft of Motor 404 rotates, driving the lower roller 403 to rotate. After being guided by the guide roller 102 near the fixed platform 4, the polyester fabric moves between the lower roller 403 and the upper roller 402. Under the rotation of the lower roller 403, the polyester fabric is discharged through the gap between the lower roller 403 and the upper roller 402. At the same time, the upper roller 402 and the lower roller 403 rotate relative to each other, squeezing the polyester fabric so that the quaternary ammonium salt solution is evenly distributed in the polyester fabric and the excess quaternary ammonium salt solution is squeezed out. The squeezed quaternary ammonium salt solution flows along the upper inclined surface of the fixed platform 4 under the action of gravity, and after being filtered by the filter screen 405, it flows back to the impregnation tank 1 for reuse, saving quaternary ammonium salt solution.

[0035] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
