Description

Technical Field

[0001] This utility model relates to the field of artificial leather impregnation processing technology, specifically an artificial leather impregnation processing device. Background Technology

[0002] Artificial leather is a type of plastic product that resembles leather. Impregnation is an important step in the production process of artificial leather. The main purpose of impregnation is to soak the fiber cloth in a polyurethane solution, allowing it to fully absorb and solidify, thereby forming artificial leather with an appearance and texture similar to genuine leather. During this process, the polyurethane solution penetrates into every crevice of the fiber cloth, enhancing the overall strength and wear resistance of the material.

[0003] The existing artificial leather impregnation processing equipment mainly consists of an impregnation tank and a conveying mechanism. When impregnating artificial leather, the artificial leather substrate is first sent into the impregnation tank containing the impregnation liquid for soaking. During the soaking process, the artificial leather substrate is smoothly and continuously sent into the impregnation tank through the continuous operation of the conveying mechanism, thereby realizing the continuous impregnation operation of the artificial leather substrate and greatly improving the work efficiency.

[0004] Existing artificial leather impregnation processing equipment results in the artificial leather substrate carrying excessive impregnation liquid during the impregnation process, leading to waste of the impregnation liquid. Furthermore, excessive impregnation liquid may cause problems such as uneven surface, spots, or uneven color after the artificial leather dries, which seriously affects the appearance and texture of the artificial leather and greatly reduces product quality. Therefore, an artificial leather impregnation processing equipment is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes an artificial leather impregnation processing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The artificial leather impregnation processing device of this utility model includes an impregnation tank. An impregnation roller is rotatably installed inside the impregnation tank. Two fixed rods are fixedly connected to both sides of the port of the impregnation tank. A guide roller is rotatably installed on the two fixed rods at the same end. Two short plates are fixedly connected to the top side of the impregnation tank. A first extrusion roller is installed between the two short plates through a first rotating shaft. A first motor is installed on one of the short plates. The output end of the first motor is connected to one end of the first rotating shaft. Two support rods are fixedly connected to the top side of the impregnation tank. An inclined plate is installed on the two support rods. A sleeve is installed on the inclined plate. A movable rod is provided inside the sleeve. A mounting seat is fixedly connected to the bottom end of the movable rod. A second extrusion roller is installed inside the mounting seat through a second rotating shaft. A second motor is installed on one side wall of the mounting seat. The output end of the second motor is connected to one end of the second rotating shaft. A sliding groove is opened on the sleeve. A sliding rod is provided inside the sliding groove. One end of the sliding rod is fixedly connected to the movable rod. The other end is fitted with a locking cap. During the impregnation process, to prevent the artificial leather substrate from carrying excessive impregnation liquid, a squeezing mechanism is set up. First, the distance between the two squeezing rollers needs to be adjusted to adapt to the squeezing and removal requirements of artificial leather of different thicknesses. The slide rod moves in the groove, which in turn pushes the movable rod to move, causing the mounting base and the second squeezing roller to move down. With the cooperation of the first squeezing roller, the second squeezing roller moves down to contact the upper surface of the artificial leather. The locking cap then fixes the slide rod, thus allowing the distance between the two squeezing rollers to be adjusted according to the different thicknesses of artificial leather to meet the squeezing requirements of artificial leather of different thicknesses. After the artificial leather is impregnated, the artificial leather substrate passes between the first and second squeezing rollers. Through the squeezing of the two squeezing rollers, excess impregnation liquid on the surface of the artificial leather can be effectively removed, reducing the waste of impregnation liquid. Through a precise impregnation and squeezing process, uniform impregnation of the artificial leather can be ensured, avoiding quality problems caused by uneven impregnation. At the same time, it reduces defects such as spots and wrinkles that appear on the artificial leather during the drying process, improving the overall aesthetics of the product.

[0007] A first scraper is installed between the two short plates, and a second scraper is installed between the two inner sidewalls of the mounting base. When squeezing to remove excess impregnation liquid, the first and second scrapers can effectively scrape off the impregnation liquid adhering to the surface of the squeezing roller, preventing the impregnation liquid from accumulating on the surface of the squeezing roller, thereby ensuring the cleanliness of the surface of the squeezing roller. A clean surface of the squeezing roller can squeeze the artificial leather more evenly, ensuring the uniform distribution of the impregnation liquid in the artificial leather. When the surface of the squeezing roller is clean, excess impregnation liquid on the surface of the artificial leather can be removed more effectively, improving the removal efficiency.

[0008] Preferably, the inclined plate has two rod holes, each containing a limit rod, which is located on both sides of the sleeve. The bottom end of each limit rod is fixed to the mounting base. Two springs are fixed between the mounting base and the inclined plate, and are correspondingly sleeved on the limit rods. When adjusting the distance between the two extrusion rollers, the cooperation of the limit rods and springs enables the movable rod to drive the mounting base and the second extrusion roller to move stably, ensuring the straightness and stability of the movable rod, the connected mounting base, and the second extrusion roller during movement. This design prevents inaccurate adjustment due to offset or swaying, ensuring precise adjustment of the distance between the extrusion rollers.

[0009] Preferably, a support frame is fixed to one side wall of the impregnation tank, and a box is installed on the support frame. The top and bottom of the box are provided with three mounting slots, and each mounting slot is equipped with a fan. Heating wires are provided at both the top and bottom of the box. A through groove is provided on the box. After the artificial leather is impregnated, when it needs to be dried, the fan operates, and with the cooperation of the heating wires, the heated high-temperature gas is blown onto the top and bottom surfaces of the artificial leather, thereby enabling the impregnated artificial leather to be dried quickly and evenly.

[0010] Preferably, two rotating rods are rotatably installed inside the impregnation tank, and multiple stirring rods are fixedly connected to each rotating rod. A pulley is fitted onto one end of each rotating rod, and a conveyor belt is fitted onto the two pulleys. An electric motor is installed on one side wall of the impregnation tank away from the conveyor belt, and the output end of the electric motor is connected to one end of the rotating rod. A drain pipe is connected to the bottom of one side of the impregnation tank. During the impregnation process, by setting up a stirring mechanism and starting the electric motor, the two pulleys drive the two rotating rods to rotate, which in turn causes the stirring rods to rotate as well. This allows for thorough stirring of the impregnation solution, ensuring that the chemical components in the impregnation solution are evenly distributed on the surface and inside of the artificial leather. This helps to avoid quality problems caused by uneven impregnation, such as uneven color and strength differences.

[0011] The advantages of this utility model are:

[0012] 1. In the impregnation process of this utility model, in order to prevent the artificial leather substrate from carrying excessive impregnation liquid, a squeezing mechanism is set up. First, the distance between the two squeezing rollers needs to be adjusted to adapt to the squeezing and removal requirements of artificial leather of different thicknesses. The slide rod moves in the slide groove, which in turn pushes the movable rod to move, causing the mounting base and the second squeezing roller to move down. With the cooperation of the first squeezing roller, the second squeezing roller moves down to contact the upper surface of the artificial leather. The slide rod is fixed by the action of the locking cap. Thus, the distance between the two squeezing rollers can be adjusted according to the artificial leather of different thicknesses to meet the squeezing requirements of artificial leather of different thicknesses. After the artificial leather is impregnated, the artificial leather substrate passes between the first and second squeezing rollers. Through the squeezing of the two squeezing rollers, the excess impregnation liquid on the surface of the artificial leather can be effectively removed, reducing the waste of impregnation liquid. Through the precise impregnation and squeezing process, the uniform impregnation of artificial leather can be ensured, avoiding quality problems caused by uneven impregnation. At the same time, it reduces the spots, wrinkles and other defects that appear on the artificial leather during the drying process, improving the overall aesthetics of the product.

[0013] 2. When removing excess impregnation liquid by squeezing, this utility model can effectively scrape off the impregnation liquid adhering to the surface of the squeezing roller by setting a first scraper and a second scraper, avoiding the accumulation of impregnation liquid on the surface of the squeezing roller, thereby ensuring the cleanliness of the surface of the squeezing roller. The clean surface of the squeezing roller can squeeze the artificial leather more evenly, ensuring the uniform distribution of impregnation liquid in the artificial leather. When the surface of the squeezing roller is clean, excess impregnation liquid on the surface of the artificial leather can be removed more effectively, improving the removal efficiency.

[0022] 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 scope of protection of the present utility model.

[0023] Please see Figure 1-5As shown, a synthetic leather impregnation processing device includes an impregnation tank 1, an impregnation roller 2 rotatably mounted inside the impregnation tank 1, two fixed rods 3 fixed to both sides of the port of the impregnation tank 1, and guide rollers 4 rotatably mounted on the two fixed rods 3 at the same end, and two short plates 5 fixed to the top side of the impregnation tank 1, with a first extrusion roller 6 mounted between the two short plates 5 via a first rotating shaft, a first motor 7 mounted on one of the short plates 5, the output end of the first motor 7 connected to one end of the first rotating shaft, two support rods 9 fixed to the top side of the impregnation tank 1, an inclined plate 10 mounted on the two support rods 9, a sleeve 11 mounted on the inclined plate 10, and a movable rod 12 disposed inside the sleeve 11. A mounting base 13 is fixedly connected to the bottom end of the device. A second extrusion roller 14 is installed inside the mounting base 13 via a second rotating shaft. A second motor 15 is installed on one side wall of the mounting base 13. The output end of the second motor 15 is connected to one end of the second rotating shaft. A sliding groove 16 is provided on the sleeve 11. A sliding rod 17 is provided in the sliding groove 16. One end of the sliding rod 17 is fixedly connected to the movable rod 12. A locking cap 18 is fitted on the other end of the sliding rod 17. A first scraper 8 is installed between the two short plates 5. A second scraper 19 is installed between the two inner side walls of the mounting base 13. During operation, in order to prevent the artificial leather substrate from carrying excessive impregnation liquid during the impregnation process, an extrusion mechanism is set up. First, the distance between the two extrusion rollers needs to be adjusted. The distance between the two extrusion rollers is adjusted to accommodate the extrusion and removal requirements of artificial leather of varying thicknesses. The slide rod 17 moves within the groove 16, which in turn moves the movable rod 12, causing the mounting base 13 and the second extrusion roller 14 to descend. With the cooperation of the first extrusion roller 6, the second extrusion roller 14 descends until it contacts the upper surface of the artificial leather. At this point, the locking cap 18 secures the slide rod 17. This allows the distance between the two extrusion rollers to be adjusted according to the different thicknesses of the artificial leather, thus meeting the extrusion requirements for different thicknesses. After the artificial leather is impregnated, the artificial leather substrate passes between the first extrusion roller 6 and the second extrusion roller 14. The extrusion of the two rollers effectively removes excess impurity from the surface of the artificial leather. By reducing the waste of impregnation liquid, the precise impregnation and squeezing process ensures uniform impregnation of the artificial leather, avoiding quality problems caused by uneven impregnation. At the same time, it reduces defects such as spots and wrinkles that appear in the artificial leather during the drying process, improving the overall appearance of the product. By setting the first scraper 8 and the second scraper 19, the impregnation liquid adhering to the surface of the squeezing roller can be effectively scraped off, avoiding the accumulation of impregnation liquid on the surface of the squeezing roller, thereby ensuring the cleanliness of the surface of the squeezing roller. The clean surface of the squeezing roller can squeeze the artificial leather more evenly, ensuring the uniform distribution of impregnation liquid in the artificial leather. With the surface of the squeezing roller clean, excess impregnation liquid on the surface of the artificial leather can be removed more effectively, improving removal efficiency.

[0024] Two rod holes are provided on the inclined plate 10, and a limit rod 20 is inserted into each of the two rod holes. The two limit rods 20 are located on both sides of the sleeve 11. The bottom end of the limit rod 20 is fixed to the mounting base 13. Two springs 21 are fixed between the mounting base 13 and the inclined plate 10, and the two springs 21 are correspondingly sleeved on the limit rods 20. When adjusting the distance between the two extrusion rollers, the cooperation of the limit rods 20 and the springs 21 enables the movable rod 12 to drive the mounting base 13 and the second extrusion roller 14 to move stably. This ensures the straightness and stability of the movable rod 12 and the connected mounting base 13 and the second extrusion roller 14 during the movement. This design prevents inaccurate adjustment due to offset or shaking, and ensures the precise adjustment of the distance between the extrusion rollers.

[0025] Please see Figure 6 As shown, a support frame 22 is fixed to one side wall of the impregnation tank 1, and a box 23 is installed on the support frame 22. Three mounting slots 24 are opened at the top and bottom of the box 23, and a fan 25 is installed in each mounting slot 24. Heating wires 26 are set at both the upper and lower ends of the box 23, and a through groove 27 is opened on the box 23. When the artificial leather needs to be dried after impregnation, the fan 25 operates, and with the cooperation of the heating wires 26, the heated high-temperature gas is blown onto the upper and lower surfaces of the artificial leather, so as to quickly and evenly dry the impregnated artificial leather.

[0026] Please see Figure 1-2 As shown, two rotating rods 28 are rotatably installed inside the impregnation tank 1. Each rotating rod 28 is fixed with multiple stirring rods 29. One end of each rotating rod 28 is fitted with a pulley 30, and the two pulleys 30 are fitted with a conveyor belt 31. An electric motor is installed on one side wall of the impregnation tank 1 away from the conveyor belt 31. The output end of the electric motor is connected to one end of the rotating rod 28. A drain pipe 32 is connected to the bottom of one side of the impregnation tank 1. During the impregnation process, by setting up a stirring mechanism and starting the electric motor, the two pulleys 30 drive the two rotating rods 28 to rotate under the cooperation of the conveyor belt 31, which in turn causes the stirring rods 29 to rotate as well. This allows for thorough stirring of the impregnation liquid, ensuring that the chemical components in the impregnation liquid are evenly distributed on the surface and inside of the artificial leather. This helps to avoid quality problems caused by uneven impregnation, such as uneven color and strength differences.

[0027] Working Principle: Existing artificial leather impregnation processing devices often result in excessive impregnation liquid carried by the artificial leather substrate during the impregnation process, leading to waste. Furthermore, excessive impregnation liquid can cause uneven surface, spots, or color variations after drying, severely affecting the appearance and texture of the artificial leather and significantly reducing product quality. Therefore, this invention addresses these issues by proposing an artificial leather impregnation processing device. During the impregnation process, to prevent the artificial leather substrate from carrying excessive impregnation liquid, an extrusion mechanism is installed. First, the distance between the two extrusion rollers needs to be adjusted to accommodate the extrusion removal requirements of artificial leather of different thicknesses. This causes the slide rod 17 to move within the groove 16, which in turn pushes the movable rod 12, causing the mounting base 13 and the second extrusion roller 14 to move downwards. With the cooperation of the first extrusion roller 6, the second extrusion roller 14 moves downwards until it contacts the upper surface of the artificial leather. At this point, the locking cap 18 secures the slide rod 17, thus allowing for adjustment according to the different thicknesses of the artificial leather. The distance between the two extrusion rollers is adjusted to meet the extrusion requirements of artificial leather of different thicknesses. After the artificial leather is impregnated, the artificial leather substrate passes between the first extrusion roller 6 and the second extrusion roller 14. The extrusion of the two rollers effectively removes excess impurity from the surface of the artificial leather, reducing waste. The precise impregnation and extrusion process ensures uniform impregnation of the artificial leather, avoiding quality problems caused by uneven impregnation. It also reduces defects such as spots and wrinkles that occur during the drying process, improving the overall aesthetics of the product. By setting the first scraper 8 and the second scraper 19, the impurity adhering to the surface of the extrusion rollers can be effectively scraped off, preventing the accumulation of impurity on the surface of the extrusion rollers and ensuring the cleanliness of the extrusion roller surface. A clean extrusion roller surface can more evenly extrude the artificial leather, ensuring uniform distribution of the impurity in the artificial leather. With a clean extrusion roller surface, excess impurity can be removed from the surface of the artificial leather more effectively, improving removal efficiency.
