Description

Technical Field

[0001] This utility model relates to the field of dyeing machine technology, and in particular to a foam dyeing machine. Background Technology

[0002] In dyeing and printing processes, in order to reduce the moisture content of the workpieces, the dyeing working solution is usually changed from liquid to foam form. Then, the foam process is used to apply the chemicals to the workpieces, which greatly reduces the moisture content of the workpieces, reduces the migration of chemicals on the workpieces, and improves the quality of dyeing and printing processes.

[0003] A related technology, Chinese Patent No. CN219079853U, discloses a foam dyeing machine, which includes a dyeing box. A feed roller is rotatably mounted on one side of the dyeing box, and a discharge roller is rotatably mounted on the other side. A set of drive motors is fixedly mounted on the outer wall of the dyeing box, and positioning rollers are fixedly mounted on the output shafts of the drive motors. The positioning rollers are rotatably positioned inside the dyeing box. The workpiece moves sequentially along the top of the feed roller, between the positioning rollers, and the top of the discharge roller. During the movement of the workpiece, the two positioning rollers rotate in opposite directions, squeezing the foam dye onto the surface of the workpiece, thus bringing the foam dye into contact with the workpiece.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: Although the two positioning rollers rotating in opposite directions can squeeze the foam dyeing agent onto the surface of the workpiece, the gap between the positioning rollers is not easy to adjust because the drive motor is fixedly installed on the dyeing box, which means that the foam dyeing machine can only be used for workpieces within a certain thickness range.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a foam dyeing machine. (Refer to...) Figures 1 to 3The dyeing box includes a dyeing chamber 1, with a feed roller 11 rotatably mounted on one side and a discharge roller 12 rotatably mounted on the other side. An upper positioning roller 2 and a lower positioning roller 3 are rotatably mounted inside the dyeing chamber 1, with the upper positioning roller 2 positioned directly above the lower positioning roller 3. An adjusting roller 9 is installed inside the dyeing chamber 1 and can move horizontally along the chamber. The adjusting roller 9, feed roller 11, discharge roller 12, upper positioning roller 2, and lower positioning roller 3 are all arranged in parallel, and the workpiece moves sequentially along the top of the feed roller 11, between the upper positioning roller 2 and the lower positioning roller 3, the bottom of the adjusting roller 9, and the top of the discharge roller 12. An upper swing arm 4, a lower swing arm 5, an upper rotating arm 6, and a lower rotating arm 7 are rotatably mounted inside the dyeing chamber 1, with the upper swing arm 4 and upper rotating arm 6 facing each other, and the lower swing arm 5 and lower rotating arm 7 facing each other. An upper motor 41 is mounted on the upper swing arm 4, and the output shaft of the upper motor 41 is rotatably connected to the upper swing arm 4. The output shaft of the upper motor 41 is welded to one end of the upper positioning roller 2, and the other end of the upper positioning roller 2 is rotatably connected to the upper rotating arm 6. A lower motor 51 is mounted on the lower swing arm 5, and the output shaft of the lower motor 51 is rotatably connected to the lower swing arm 5. The output shaft of the lower motor 51 is welded to one end of the lower positioning roller 3, and the other end of the lower positioning roller 3 is rotatably connected to the lower rotating arm 7. When the workpiece passes between the upper positioning roller 2 and the lower positioning roller 3, the upper motor 41 drives the upper positioning roller 2 to rotate, and the lower motor 51 drives the lower positioning roller 3 to rotate, causing the upper and lower positioning rollers to rotate towards each other, squeezing the foam dye onto the surface of the workpiece. The upper rotating arm 6 and the upper swing arm 4 rotate synchronously, driving the upper positioning roller 2 to move, and the lower rotating arm 7 and the lower swing arm 5 rotate synchronously, driving the lower positioning roller 3 to move, thereby adjusting the distance between the upper and lower positioning rollers 2 and 3. This facilitates the passage of workpieces of different thicknesses between the upper and lower positioning rollers 2 and 3, improving the applicability of the dyeing machine.

[0035] Reference Figures 1 to 3 An upper cover 42 is installed on the upper swing arm 4, and the upper motor 41 is located in a closed space between the upper cover 42 and the upper swing arm 4, reducing the corrosion of the upper motor 41 by chemicals. A lower cover 52 is installed on the lower swing arm 5, and the lower motor 51 is located in a closed space between the lower cover 52 and the lower swing arm 5, reducing the corrosion of the lower motor 51 by chemicals.

[0036] Reference Figures 1 to 4 An upper rotating shaft 61 is installed through the side wall of the dyeing box 1, and is rotatably connected to the dyeing box 1. One end of the upper rotating shaft 61 inside the dyeing box 1 is welded to the upper rotating arm 6, and the other end of the upper rotating shaft 61 outside the dyeing box 1 is fitted with an upper gear 62. An upper rack 63 is slidably mounted on the side wall of the dyeing box 1, and meshes with the upper gear 62. When the upper rotating arm 6 and the upper swing arm 4 are driven to rotate synchronously, causing the upper positioning roller 2 to move, the upper rack 63 moves, causing the upper gear 62 to rotate. The rotation of the upper gear 62 causes the upper rotating shaft 61 to rotate, and the upper rotating shaft 61 causes the upper rotating arm 6 to swing.

[0037] Reference Figures 1 to 4 A lower rotating shaft 71 is installed through the side wall of the dyeing box 1, and is rotatably connected to the dyeing box 1. One end of the lower rotating shaft 71 inside the dyeing box 1 is welded to the lower rotating arm 7, and the other end of the lower rotating shaft 71 outside the dyeing box 1 is fitted with a lower gear 72. A lower rack 73 is slidably mounted on the side wall of the dyeing box 1, and meshes with the lower gear 72. When the lower rotating arm 7 and the lower swing arm 5 are driven to rotate synchronously, causing the lower positioning roller 3 to move, the lower rack 73 moves, causing the lower gear 72 to rotate. The rotation of the lower gear 72 causes the lower rotating shaft 71 to rotate, and the lower rotating shaft 71 causes the lower rotating arm 7 to swing.

[0038] Reference Figures 1 to 5 A drive block 8 is welded between the bottom of the upper rack 63 and the top of the lower rack 73. A drive slide rod 82 is threaded through the drive block 8 and slidably connected to the drive block 8. Drive seats 81 are installed at both ends of the drive slide rod 82 and are welded to the side wall of the dyeing box 1. A drive screw 83 is rotatably mounted between the drive seats 81 and is threadedly connected to the drive block 8. Rotating the drive screw 83 causes the drive block 8 to move along the drive slide rod 82. The sliding of the drive block 8 causes the upper rack 63 and the lower rack 73 to move synchronously, achieving the effect of synchronously driving the upper positioning roller 2 and the lower positioning roller 3.

[0039] The implementation principle of a foam dyeing machine according to an embodiment of this application is as follows: When the workpiece passes between the upper positioning roller 2 and the lower positioning roller 3, the upper motor 41 drives the upper positioning roller 2 to rotate, and the lower motor 51 drives the lower positioning roller 3 to rotate, causing the upper positioning roller 2 and the lower positioning roller 3 to rotate towards each other, squeezing the foam dye onto the surface of the workpiece. When the distance between the upper positioning roller 2 and the lower positioning roller 3 is adjusted, the drive screw 83 is rotated, and the drive screw 83 drives the drive block 8 to move along the drive slide bar 82. The sliding of the drive block 8 drives the upper rack 63 and the lower rack 73 to move synchronously. The movement of the upper rack 63 drives the upper gear 62 to rotate, and the rotation of the upper gear 62 drives the upper rotating shaft 61 to rotate. The upper rotating shaft 61 drives the upper rotating arm 6 to swing, thereby driving the upper rotating arm 6 and the upper swing arm 4 to swing synchronously, driving the upper positioning roller 2 to move. The movement of the lower rack 73 drives the lower gear 72 to rotate, which in turn drives the lower rotating shaft 71 to rotate. The lower rotating shaft 71 then drives the lower rotating arm 7 to swing, thereby causing the lower rotating arm 7 and the lower swing arm 5 to swing synchronously and move the lower positioning roller 3. This allows workpieces of different thicknesses to pass between the upper positioning roller 2 and the lower positioning roller 3, thus improving the applicability of the dyeing machine.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
