[0015] 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.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a dyeing apparatus for producing spunlace nonwoven fabric, comprising: Dyeing frame 1 and mounting bracket 2 disposed within dyeing frame 1; The mounting frame 2 has several winding rollers 3 rotatably mounted inside, which are used for placing non-woven fabric. Both sides of the mounting frame 2 are provided with flattening mechanisms 4, which are used for straightening non-woven fabric. The mounting frame 2 is also provided with a guide mechanism 5. Among them, the guide mechanism 5 is used to prevent the non-woven fabric from moving and falling off. The guide mechanism 5 includes a frame 51 fixedly installed on the inner wall of the mounting frame 2. A threaded rod 52 is rotatably installed inside the frame 51. A guide plate 53 is threadedly installed on the surface of the threaded rod 52. A rolling element 50 is provided inside the guide plate 53.

[0017] The rolling element 50 includes a rectangular groove 501 formed in the guide plate 53. A plurality of contact rollers 502 are rotatably mounted inside the rectangular groove 501, and the surfaces of the plurality of contact rollers 502 are all in contact with the surface of the nonwoven fabric. In this embodiment, one end of the nonwoven fabric passes through the groove 41 on one side of the mounting frame 2, and the nonwoven fabric is wound around several winding rollers 3 and extends out from another groove 41. The nonwoven fabric is located between the lower roller 42 and the upper roller 45 in the groove 41. Two springs 43 push the floating frame 44 to drive the upper roller 45 to press the nonwoven fabric, which flattens the two ends of the nonwoven fabric. The handwheel 7 is rotated to drive the threaded rod 52 to rotate. The surface of the threaded rod 52 is threaded with the inside of the guide plate 53. The inside of the guide plate 53 contacts the roller 502 to fit the side edge of the nonwoven fabric. By activating the two heating rods 81 inside the dyeing frame 1, the dye inside the frame 1 is heated, allowing the dye to dissolve more completely. Heated dye also provides better coloring results on the non-woven fabric. Dye concentration is a crucial factor affecting the dyeing effect. Too high a concentration may result in an overly dark and uneven color, while too low a concentration may result in an overly light color. Activating the motor 82 drives the stirring paddle 83 to rotate, further agitating the dye inside the dyeing frame 1.

[0018] Two slide rods 6 are slidably installed inside the guide plate 53. Both slide rods 6 are fixedly installed inside the frame 51. A handwheel part 7 is fixedly installed at one end of the threaded rod 52. Furthermore, two sliding rods 6 are provided inside the guide plate 53, which enhance the guiding effect of the movement of the guide plate 53 and prevent the guide plate 53 from rotating.

[0019] It also includes a preheating mechanism 8 for heating the dye inside the dyeing frame 1. The preheating mechanism 8 includes two heating rods 81 installed on the inner wall of the dyeing frame 1, and a motor 82 is fixedly installed at the bottom of the dyeing frame 1. The output end of the motor 82 passes through the bottom of the inner wall of the dyeing frame 1 and is equipped with a stirring paddle 83. Specifically, the two heating rods 81 inside the dyeing frame 1 are activated to heat the dye inside the dyeing frame 1, so that the dye dissolves more fully and the dyeing effect on the non-woven fabric is better after heating. The motor 82 is activated to drive the stirring paddle 83 to rotate and stir the dye inside the dyeing frame 1 more fully.

[0020] The bottom of the inner wall of the dyeing frame 1 is provided with a slope, and a drain valve pipe 9 is connected to the groove at the bottom of the inner wall of the dyeing frame 1. It is worth noting that the bottom of the inner wall of the dyeing frame 1 is provided with a slope to facilitate the discharge of dye from the dyeing frame 1, and the drain valve pipe 9 is located in the groove at the bottom of the inner wall of the dyeing frame 1, so as to discharge the dye from the dyeing frame 1 more thoroughly.

[0021] The flattening mechanism 4 includes a groove 41 formed on the surface of the mounting frame 2. A lower roller 42 is rotatably mounted inside the groove 41. Two springs 43 are snapped onto the top of the groove 41. A floating frame 44 is fixedly mounted at the lower end of the two springs 43. An upper roller 45 is rotatably mounted inside the floating frame 44. A pulling frame 46 is fixedly mounted on the top of the floating frame 44. The surface of the pulling frame 46 is slidably mounted to the interior of the mounting frame 2. It should be noted that the nonwoven fabric is located between the lower roller 42 and the upper roller 45 in the trough 41. Two springs 43 push the floating frame 44 to drive the upper roller 45 to press the nonwoven fabric, which flattens the two ends of the nonwoven fabric.

[0022] A fixing frame 10 is fixedly installed on the surface of the dyeing frame 1. Two cylinders 11 are embedded in both sides of the fixing frame 10. Push plates 12 are fixedly installed on both sides of the mounting frame 2. The extended ends of the two cylinders 11 are fixedly installed at the bottom of the push plate 12. The four cylinders 11 inside the fixed frame 10 are synchronous cylinders 11, which are used to lift the mounting frame 2, so that the non-woven fabric can be placed on the winding roller 3 inside the mounting frame 2. They are also easy to disassemble and easier to clean the mounting frame 2.

[0023] This device inserts one end of a nonwoven fabric through a groove 41 on one side of the mounting frame 2, wraps the nonwoven fabric around several winding rollers 3, and extends it out from another groove 41. The nonwoven fabric is located between the lower roller 42 and the upper roller 45 in the groove 41. Two springs 43 push the floating frame 44 to drive the upper roller 45 to press and hold the nonwoven fabric, flattening both ends of the nonwoven fabric. Rotating the handwheel 7 drives the threaded rod 52 to rotate, and the surface of the threaded rod 52 is threaded into the guide plate 53. The contact roller 502 inside the guide plate 53 is in contact with the side edge of the nonwoven fabric. By activating the two heating rods 81 inside the dyeing frame 1, the dye in the dyeing frame 1 is heated, allowing the dye to dissolve more fully. The heated dye has a better coloring effect on the nonwoven fabric. Dye concentration is an important factor affecting the dyeing effect. Too high a concentration may result in an overly dark and uneven color, while too low a concentration may result in an overly light color. Activating the motor 82 drives the stirring paddle 83 to rotate, further agitating the dye in the dyeing frame 1.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
