Description

Technical Field

[0001] The utility model relates to the technical field of dyeing equipment, in particular to a color fixing device for ultra-fine fiber synthetic leather. Background Technique

[0002] Ultra-fine fiber synthetic leather is based on sea-island fiber non-woven fabric as the substrate, impregnated with polyurethane slurry and formed into a sea-island fiber / polyurethane composite material after wet coagulation, and then the sea-island fiber is opened to obtain an ultra-fine fiber / polyurethane composite material. When the ultra-fine fiber synthetic leather impregnated with the dye solution is irradiated by microwaves, due to the action of the high-frequency microwave electric field on the dipoles of the polar molecules in the fiber, repeated polarization and change of the arrangement direction occur, and friction occurs repeatedly between the molecules to generate heat, so that the energy of the absorbed electromagnetic wave can be quickly converted into heat energy. At the same time, under the action of microwaves, some dye molecules can also be induced to heat up, so as to achieve the purpose of rapid dyeing and color fixing.

[0003] According to a disclosed microwave heating color fixing machine (publication number: CN209890653U), in the above application, by setting an active roller shaft and a driving structure for driving the active roller shaft to rotate, the active roller shaft can rotate actively, so as to reduce the friction between the leather or fabric and the roller shaft, facilitate the transmission of the leather or fabric, so that the leather or fabric is not easily scratched, and further achieve the purpose of convenient color fixing and good color fixing effect.

[0004] However, in the actual use process of the above equipment, when the roller for pulling the ultra-fine fiber synthetic leather rotates, the moisture on the surface is easily squeezed out due to extrusion and friction between the contact parts of the roller and the ultra-fine fiber synthetic leather. These moisture adheres to the surface of the roller, which may affect the color fixing effect on the surface of the ultra-fine fiber synthetic leather during the microwave heating process, and further reduce the production quality of the ultra-fine fiber synthetic leather. In view of this, we propose a color fixing device for ultra-fine fiber synthetic leather. Content of the Utility Model

A conveying mechanism 7 is arranged inside the machine body 1, and the conveying mechanism 7 includes a mounting plate 71, a roller 72, an arc-shaped straight groove 73, an arc-shaped blocking belt 74, an annular arc groove 75, a diversion hole 76, a drainage cavity 77, a drainage port 78 and a collecting trough plate 79.

[0025] In an embodiment of the present utility model, a mounting plate 71 is fixedly installed on the inner wall of the machine body 1, a roller 72 is penetrated and rotatably installed on the inner wall of the mounting plate 71, an arc-shaped straight groove 73 is opened on the arc-shaped outer wall of the roller 72, an arc-shaped blocking belt 74 is fixedly installed on the inner wall of the arc-shaped straight groove 73 close to one side of the arc-shaped outer surface of the roller 72, an annular arc groove 75 is opened on the arc-shaped outer wall of the roller 72, a diversion hole 76 is opened at the bottom end of the annular arc groove 75, a drainage cavity 77 is opened at the center of the roller 72, drainage ports 78 are opened on the inner walls at both ends of the roller 72, and a collecting trough plate 79 is fixedly installed on the inner wall of the machine body 1.

[0026] Furthermore, the control panel 2 is electrically connected to the microwave heating tubes 4 and the driving motor 6, so that the staff can adjust the working states of the microwave heating tubes 4 and the driving motor 6 by operating the control panel 2 to facilitate the development of the color-fixing processing operation of the superfine fiber synthetic leather. At the same time, the number of the reels 5 and the driving motors 6 is set to two groups, and the two groups of driving motors 6 and reels 5 are symmetrically arranged with the vertical central axis of the machine body 1 as the axis of symmetry to achieve continuous and stable heat setting of the superfine fiber synthetic leather inside the machine body 1. In addition, the number of the mounting plates 71 is set to four, and the four mounting plates 71 are arranged in two groups in a mirror image on the left and right sides of the upper and lower inner walls of the machine body 1, so as to facilitate the erection and installation of the rollers 72 on the upper and lower sides inside the machine body 1. Specifically, insertion holes adapted to the outer diameter of the roller 72 are opened on the inner wall of the mounting plate 71, so as to ensure that the roller 72 can rotate stably inside the machine body 1 without deviation, and at the same time ensure the stable transmission requirement of the superfine fiber synthetic leather. In addition, the number of the rollers 72 is set to multiple groups, and the multiple groups of rollers 72 are evenly distributed in a linear array on the inner wall of the mounting plate 71, so that the superfine fiber synthetic leather fabric inside the machine body 1 can obtain a longer stroke of heat effect and improve the color-fixing effect after the superfine fiber synthetic leather fabric is colored.

[0027] In addition, multiple sets of arc-shaped straight grooves 73 are provided, and the multiple sets of arc-shaped straight grooves 73 are evenly distributed in a circumferential array on the arc-shaped outer wall of the roller 72. Moreover, the arc-shaped straight grooves 73 are arranged with a narrower side closer to the center of the roller 72 and a wider side farther from the center of the roller 72. At the same time, the arc-shaped blocking band 74 is arranged to be inclined on the side closer to the center of the arc-shaped straight groove 73, so that the water droplets generated on the surface of the roller 72 due to high temperature and extrusion can flow more easily into the interior of the arc-shaped straight groove 73. And due to the inclined arrangement of the arc-shaped blocking band 74, the water droplets entering the arc-shaped straight groove 73 will not flow back easily as the roller 72 rotates, reducing the influence of the water droplets on the color fixation effect of the surface of the microfiber synthetic leather. Further, due to the inclined arrangement of the arc-shaped blocking band 74, the edge of the opened arc-shaped straight groove 73 is prevented from wearing the surface of the microfiber synthetic leather. Specifically, the annular arc groove 75 and the arc-shaped straight groove 73 are arranged perpendicular to each other. And multiple sets of annular arc grooves 75 are provided, and the multiple sets of annular arc grooves 75 are evenly distributed in a linear array on the arc-shaped outer wall of the roller 72. In addition, the diversion hole 76 is arranged in a frustum shape including a large-diameter end and a small-diameter end, and the small-diameter end is arranged closer to the center of the roller 72, so as to facilitate the water droplets in the annular arc groove 75 to flow to the drainage cavity 77 opened at the center of the roller 72, while reducing the situation that the water in the drainage cavity 77 flows into the annular arc groove 75 through the diversion hole 76.

[0028] Specifically, multiple sets of drain ports 78 are provided, and the multiple sets of drain ports 78 are evenly distributed in a circumferential array on the arc-shaped outer wall of the roller 72. And the drain ports 78 and the collection trough plate 79 are arranged in the same plane, so that the water droplets flowing out of the drain ports 78 will directly fall into the collection trough plate 79 and be discharged outward. At the same time, the diameter of the drainage cavity 77 on the side closer to the vertical central axis of the roller 72 is smaller than the diameter of the end of the drainage cavity 77 farther from the vertical central axis of the roller 72, so that the water droplets entering the drainage cavity 77 will flow towards both ends under the action of gravity and be discharged outward more freely through the drain ports 78.

[0029] In the embodiment of the present utility model, a gas guiding structure 8 is provided on the arc-shaped outer wall of the roller 72. The gas guiding structure 8 includes an annular groove 81. An annular groove 81 is opened on the arc-shaped outer wall at the end of the roller 72. A gas guiding groove 82 is opened on the arc-shaped outer wall of the roller 72. The gas guiding groove 82 is connected to the annular groove 81 in a through manner. And multiple sets of gas guiding grooves 82 are provided, and the multiple sets of gas guiding grooves 82 are evenly distributed in a circumferential array on the arc-shaped outer wall of the roller 72. Specifically, the gas guiding groove 82 is arranged between two adjacent sets of arc-shaped straight grooves 73, so that the air in the internal environment of the machine body 1 enters the contact part between the roller 72 and the microfiber synthetic leather through the gas guiding structure 8, so as to improve the heating effect of the contact part between the microfiber synthetic leather and the roller 72, ensure the color fixation effect of the device on the microfiber synthetic leather, and improve the production quality of the microfiber synthetic leather.

[0030] In the present utility model, during use, first, the machine body 1 is opened, and the ultra-fine fiber synthetic leather is sequentially passed through each roller 72. Then, the winding rollers and unwinding rollers are respectively set for the reels 5 on the left and right sides inside the machine body 1. Next, the closing door of the machine body 1 is closed. At this time, the microwave heating tube 4 is started through the control panel 2, and the drive motor 6 on one side of the machine body 1 is started to drive the winding roller to rotate. With the arrangement of several rollers 72, the ultra-fine fiber synthetic leather is continuously and slowly heated inside the machine body 1, so that the ultra-fine fiber synthetic leather dyed with dye is continuously heated to achieve a color-fixing effect and ensure the production quality of the ultra-fine fiber synthetic leather. At the same time, through the arrangement of the conveying mechanism 7, when the ultra-fine fiber synthetic leather comes into contact with the roller 72, due to the inclined arc-shaped blocking belt 74, the water droplets generated on the surface of the roller 72 due to high temperature and extrusion will more easily flow into the interior of the arc-shaped straight groove 73. Furthermore, the water droplets entering the arc-shaped straight groove 73 will not easily flow back with the rotation of the roller 72, reducing the influence of the water droplets on the color-fixing effect of the surface of the ultra-fine fiber synthetic leather. Finally, the water droplets pass through the diversion holes 76 and the drainage cavity 77, and are discharged outwards through the drain port 78 into the collection trough plate 79 to ensure the production quality of the ultra-fine fiber synthetic leather.

[0031] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present utility model are all within the protection scope of the present utility model.
