Description

Technical Field

[0001] This invention belongs to the field of fabric coating pretreatment technology, specifically relating to a coating pretreatment device that can improve color fastness. Background Technology

[0002] Fabric lamination refers to the process of covering the surface of fabric with a thin film material, which can effectively improve the color fastness of the fabric. Pre-treatment of the fabric, such as washing and disinfection, can effectively improve the lamination effect, thereby indirectly improving the color fastness of the fabric.

[0003] Some existing technologies also include fabric cleaning solutions, such as a Chinese patent with publication number CN108166184B, which discloses a fabric cleaning device that uses a nozzle to spray water onto the bottom of the fabric to wash away the floating dye, thus solving the problem that water with floating dye remains on the top of the fabric after the nozzle sprays water from below.

[0004] However, this method can only clean easily removable dirt on the fabric and cannot deal with stubborn residues from the fabric production process, resulting in poor cleaning performance. Summary of the Invention

[0005] The purpose of this invention is to provide a coating pretreatment device that can improve color fastness in order to solve the problems mentioned in the background art.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] A pre-treatment apparatus for improving color fastness is used to clean fabrics, including a cleaning tank for storing cleaning solution, wherein the cleaning tank is provided with a winding mechanism, a washing mechanism, and a drive mechanism for simultaneously driving the winding mechanism and the washing mechanism.

[0008] The washing mechanism includes two horizontally mirror-symmetrical washing components. Each washing component includes two vertically distributed and parallel washing rollers. The washing rollers in the two washing components are at an angle to their mirror plane so that the fabric is pulled towards its edge. Under the action of the pulling force, the fabric is flatly rolled up on the winding mechanism. The washing rollers are rotatably mounted on the washing tank. One end of the washing roller outside the washing tank is provided with a driven wheel. The outer rings of the driven wheels on the two washing rollers of the same washing component are in contact so that the two washing rollers keep rotating in opposite directions. The fabric passes through the middle of the vertically distributed washing rollers.

[0009] After the drive mechanism drives the washing mechanism to clean the surface of the fabric, the fabric is then wound up by the winding mechanism.

[0010] Preferably, the drive mechanism includes two drive motors mounted on the washing tank, one of which is a dual-shaft motor. Both drive motors have a drive wheel at the first output shaft end. The drive wheel contacts the outer ring of one of the driven wheels in the washing assembly to drive the driven wheel to rotate.

[0011] The second output shaft of the dual-shaft drive motor is equipped with a transmission component. The drive motor is connected to a gearbox via the transmission component, and the gearbox is connected to the winding mechanism.

[0012] The drive motor adjusts the direction of the driving and driven wheels to make the washing rollers clean the impurities on the fabric in a direction away from the winding mechanism.

[0013] Preferably, the winding mechanism includes two supports disposed in the washing tank, and a winding shaft is disposed between the two supports. The winding shaft is connected to a gearbox to realize the change of winding shaft speed.

[0014] Preferably, the transmission component is a synchronous belt or a chain.

[0015] Preferably, the washing assembly further includes a water supply component, a mounting plate disposed on the winding mechanism, and a plurality of nozzles disposed along the length of the mounting plate. The water supply component is connected to the nozzles via a water pipe and provides water flow to the nozzles for rinsing the fabric surface.

[0016] Preferably, the water supply component includes a first telescopic rod and a second telescopic rod, and one-way valves are provided on the first telescopic rod and the second telescopic rod as well as inside the water pipe, so that the first telescopic rod and the second telescopic rod draw water from the cleaning pool and deliver it to the nozzle through the water pipe;

[0017] The transmission component is also connected to a rotating wheel, and the rotating wheel is provided with a connecting rod located at a non-center position. The connecting rod is provided with a crank, and the end of the crank away from the connecting rod is connected to the first telescopic rod. The bottom end of the first telescopic rod is fixedly installed on the washing pool with its bottom facing down. The crank presses the first telescopic rod downward so that the water inside the first telescopic rod flows to the nozzle.

[0018] The winding mechanism is fixedly equipped with a second telescopic rod, which is vertically downward. The crank is equipped with a connecting plate that connects to the bottom end of the second telescopic rod. The crank drives the second telescopic rod upward to shorten it so that the water inside the second telescopic rod flows to the nozzle.

[0019] The No. 1 telescopic rod and the No. 2 telescopic rod are used to provide uninterrupted water supply to the nozzles, and the No. 1 telescopic rod and the No. 2 telescopic rod provide water intermittently.

[0020] Preferably, the mounting plate is provided with a movable plate that can move along its length. A spring for controlling the position of the movable plate is provided between the end of the movable plate away from the crank and the mounting plate. The nozzle is provided on the movable plate. A guide plate with a wave-like undulation is provided on the crank. The end of the movable plate near the crank is in contact with the guide plate. When the guide plate moves up and down, it drives the movable plate to produce horizontal reciprocating movement in the opposite direction.

[0021] Preferably, the one-way valves on the first and second telescopic rods are equipped with filters so that the water drawn in by the first and second telescopic rods is clean water.

[0022] The beneficial effects of this invention are as follows:

[0023] This invention utilizes a rotating washing roller to deeply clean the surface of the fabric, removing stubborn residues and resulting in a clean and hygienic fabric surface, thus improving the coating effect. Attached Figure Description

Detailed Implementation

[0031] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] Example 1

[0033] like Figure 1-6 As shown, a pre-treatment device for coating that can improve color fastness is used to clean fabric a. It includes a cleaning tank 1 for storing cleaning solution. The cleaning tank 1 is equipped with a winding mechanism, a washing mechanism, and a drive mechanism for simultaneously driving the winding mechanism and the washing mechanism.

[0034] The winding mechanism includes two supports 7 fixedly installed in the washing tank 1, a roller 8 rotatably installed between the two supports 7, and a gearbox 6 connected to the end of the roller 8.

[0035] The washing mechanism includes two horizontally mirror-symmetrical washing components. Each washing component includes two vertically distributed and parallel washing rollers 2. The washing rollers 2 in the two washing components are at an angle to their mirror plane, so that the fabric a is pulled towards its edge. Under the action of the pulling force, the fabric a is rolled up flat on the winding mechanism. The washing rollers 2 are rotatably mounted on the side wall of the washing tank 1. A driven wheel 3 is fixedly provided at one end of the washing roller 2 outside the washing tank 1. The outer rings of the driven wheels 3 on the two washing rollers 2 of the same washing component are in contact so that the two washing rollers 2 keep rotating in opposite directions. The fabric a passes between the vertically distributed washing rollers 2.

[0036] The drive mechanism includes two drive motors 4 fixedly mounted on the washing tank 1. One of the drive motors 4 is a dual-axis motor, that is, it has a first output shaft and a second output shaft. The first output shaft ends of both drive motors 4 are fixedly equipped with drive wheels 20. The drive wheels 20 contact the outer ring of one of the driven wheels 3 in the washing assembly to drive the driven wheel 3 to rotate.

[0037] The second output shaft of the dual-shaft drive motor 4 is equipped with a transmission component 5 via a sprocket or synchronous belt pulley. The transmission component 5 is a chain or synchronous belt. Driven by the drive motor 4, the transmission component 5 rotates, which in turn drives the gearbox 6. Under the control of its own controller, the gearbox 6 adjusts its gear to change the rotational speed of the roll 8 accordingly. This ensures that the winding speed remains the same even when the thickness of the fabric a on the roll 8 changes.

[0038] It should be noted that one end of the rolled fabric a is passed through the space reserved between the upper and lower washing rollers 2, ensuring that both the upper and lower washing rollers 2 can contact the fabric a. The end of the fabric a is then fixed to the roll 8. During washing, both drive motors 4 start simultaneously, driving the drive wheel 20 to rotate. The drive wheel 20, through friction, drives the driven wheel 3 to rotate, thus causing all the washing rollers 2 to rotate. Because the two washing rollers 2 rotate in opposite directions, the upper and lower washing rollers 2 rotate in opposite directions. Furthermore, by adjusting the direction of the drive wheel 20 and the driven wheel 3, a washing force is applied to the fabric a away from the roll 8 when the washing rollers 2 contact it, resulting in a more thorough cleaning of the fabric a. Furthermore, the washing rollers 2 are inclined, and the washing rollers 2 on both sides of fabric a can apply a pulling force to both sides of fabric a, so that fabric a is stretched flat when passing through the washing rollers 2. This not only allows fabric a to be cleaned more thoroughly and comprehensively, but also allows fabric a to be rolled up by the roller 8 in a completely flat state, avoiding wrinkles on the roller 8. After the fabric a has finished washing, it is completely wound on the roller 8. The speed reducer 6 accelerates the rotation of the roller 8, and the roller 8 drives the fabric a to rotate quickly, shaking off the water on the fabric a. Then, the cleaning solution in the washing tank 1 is replaced with clean water, and the fabric a is washed.

[0039] Furthermore, the washing assembly also includes a water supply unit, a mounting plate 9 disposed on the winding mechanism, and a plurality of nozzles 10 arranged along the length of the mounting plate 9. The water supply unit is connected to the nozzles 10 through a water pipe and provides water flow to the nozzles 10 for rinsing the surface of fabric a. When fabric a passes over the mounting plate 9, it passes under the mounting plate 9. The mounting plate 9 restricts the path of fabric a, so that fabric a has a large slope. The nozzles 10 aim at the slope and wash the fabric a to remove dirt that was not completely removed at the washing roller 2, further improving the cleaning effect.

[0040] The water supply system includes a first telescopic rod 11 and a second telescopic rod 12. One-way valves are installed on both the first and second telescopic rods 11 and inside the water pipes, allowing them to draw water from the cleaning tank 1 and deliver it to the spray nozzles 10 via the water pipes. Filters are installed at the one-way valves on the first and second telescopic rods 11 and 12 to ensure that the water drawn in by the first and second telescopic rods 11 and 12 is clean water. Activated carbon filtration can be used for the filters.

[0041] A rotating wheel 13 is rotatably connected to the transmission component 5. The rotating wheel 13 can be a link pulley or a synchronous belt pulley. A connecting rod 14 located at a non-central position is rotatably mounted on the rotating wheel 13. A crank 15 is rotatably mounted on the connecting rod 14. The end of the crank 15 away from the connecting rod 14 is rotatably connected to the first telescopic rod 11. The bottom end of the first telescopic rod 11 is fixedly mounted on the cleaning tank 1 with its bottom facing downwards. The crank 15 presses the first telescopic rod 11 downwards, causing the water inside the first telescopic rod 11 to flow towards the nozzle 10.

[0042] A second telescopic rod 12 is fixedly mounted on the bracket 7. The second telescopic rod 12 is vertically downward. A connecting plate 16 connecting the bottom end of the second telescopic rod 12 is fixedly mounted on the crank 15. The crank 15 drives the second telescopic rod 12 upward to shorten so that the water inside the second telescopic rod 12 flows to the nozzle 10.

[0043] Telescopic rod 11 and telescopic rod 12 are used to continuously supply water to nozzle 10, and the telescopic rods 11 and 12 supply water intermittently. Using the high-pressure water sprayed from nozzle 10 to rinse the surface of fabric a allows for secondary cleaning of the fabric a, further removing some adhering impurities.

[0044] Furthermore, the mounting plate 9 is provided with a sliding groove, within which a movable plate 17, movable along the length of the mounting plate 9, is movably mounted. A spring 18, controlling the position of the movable plate 17, is located between the end of the movable plate 17 furthest from the crank 15 and the mounting plate 9. A nozzle 10 is mounted on the movable plate 17. A wavy guide plate 19 is fixed to the crank 15. A pulley is located at the end of the movable plate 17 near the crank 15, and the pulley contacts the guide plate 19. When the guide plate 19 moves up and down, it cooperates with the spring 18 to drive the movable plate 17 to reciprocate horizontally in opposite directions. The movement of the movable plate 17 drives the nozzle 10 to move horizontally, allowing the nozzle 10 to achieve full-coverage cleaning of the fabric a. The nozzle 10 has small nozzle holes, resulting in a fine water stream with high impact force. The rinsing direction of the nozzle 10 is angled downwards, causing impurities to be flushed downwards and flow into the cleaning tank 1 with the water flow.

[0045] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
