Through the above structure, the diffusion efficiency of the dye in the loose wool fiber is effectively improved, so that the time required for dyeing is further reduced on the basis of the original central drainage pipe structure.

[0004] The above patent effectively improves the diffusion efficiency of the dye in the loose wool fibers by setting up a central drainage pipe. However, after dyeing, the device is unable to dehydrate the moisture inside the loose fibers, so that the dye attached to the fiber surface will dissolve again, resulting in color difference and color stains on the loose fibers, affecting subsequent processing. For this reason, the present application provides a loose fiber acid dyeing device. Utility Model Content

[0005] The purpose of the present application is to provide a loose fiber acid dyeing device to solve the problem that the device cannot dehydrate the internal moisture of the loose fibers, resulting in color difference and color stains on the loose fibers.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A loose fiber acid dyeing device comprises a base, a support frame fixedly connected to the top of the base, a controller fixedly connected to one side of the support frame, a dyeing cylinder fixedly connected to the top of the base, a support plate installed inside the dyeing cylinder, a gauze cage installed on the top of the support plate, a central drainage pipe fixedly connected to the inside of the dyeing cylinder, filter holes are provided on the gauze cage and the central drainage pipe, a stirring assembly is installed inside the dyeing cylinder, a cavity is provided inside the dyeing cylinder, a heating element is installed in the cavity, and a dehydration assembly is installed on one side of the support frame.

[0008] By adopting the above technical solution, the acidic dyeing liquid is poured into the dyeing cylinder, and then the sarong containing the loose fibers is placed on the top of the support plate. At this time, the loose fibers inside the sarong will gradually absorb the dyeing liquid inside the dyeing cylinder for dyeing. During the dyeing process, the stirring component and the heating element can be started to operate together. The operation of the stirring component can prevent the pigment in the internal dyeing liquid from precipitating, so as not to affect the dyeing effect of the loose fibers. The operation of the heating element can heat the dyeing liquid to promote the dissolution of the dye. After the dyeing of the loose fibers is completed, the loose fibers inside the sarong can be squeezed by the dehydration component to squeeze out the water inside the loose fibers, perform preliminary dehydration, and prevent the dye attached to the fiber surface from dissolving again.

[0010] By adopting the above technical solution, the starting motor drives gear one to rotate. Since gear one is meshed with gear two and gear three, when gear one rotates, gear two and gear three are driven to rotate together.

[0011] Furthermore, two rotating rods are rotatably connected to the fixed block, and the gear two and gear three are respectively fixedly connected to the two rotating rods. One end of the two rotating rods away from the fixed block is located inside the dyeing cylinder, and multiple stirring blades are fixedly connected to the two rotating rods.

[0012] By adopting the above technical solution, when the two rotating rods rotate continuously, the multiple stirring blades will evenly stir the acidic dyeing liquid inside the dyeing cylinder, thereby preventing the pigment in the internal dyeing liquid from precipitating and affecting the dyeing effect of the loose fibers.

[0013] Furthermore, the outer surfaces of the plurality of stirring blades are coated with an anti-corrosion layer.

[0014] By adopting the above technical solution, since the dye is acidic, the anti-corrosion layer can prevent the stirring blade from being corroded after long-term use, thereby increasing the service life of the stirring blade.

[0015] Furthermore, the heating element includes an electric heating wire evenly fixedly connected to the inside of the dyeing cylinder, an infrared sensor is fixedly connected to the bottom of the support frame, the infrared sensor is electrically connected to the controller, the electric heating wire is electrically connected to the controller, and a heat conducting plate is fixedly connected to the inner wall of the dyeing cylinder.

[0016] By adopting the above technical solution, when the temperature of the liquid is too high, the controller can control the electric heating wire to lower the temperature to prevent the high temperature from affecting the dyeing of the internal loose fibers. The electric heating wire heats the liquid to promote the dissolution of the dye, accelerate the chemical reaction in the liquid, and help the dye better penetrate the interior of the loose fibers.

[0017] Furthermore, the dehydration assembly includes a fixed plate fixedly connected to one side of the support frame, a hydraulic cylinder is fixedly connected to the top of the fixed plate, the hydraulic cylinder includes a piston rod, the piston rod passes through the fixed plate, and an extrusion plate is fixedly connected to the bottom of the piston rod.

[0018] By adopting the above technical solution, the hydraulic cylinder is started to drive the squeezing plate to descend, and the loose fibers are squeezed to simply dehydrate the dyed loose fibers, so as to prevent the dye attached to the fiber surface from dissolving again, resulting in color difference and color stains.

[0019] Furthermore, a guide rod is slidably connected to the fixed plate, the bottom of the guide rod is fixedly connected to the top of the extrusion plate, and the shape and size of the extrusion plate are consistent with the inside of the yarn cage.

[0020] By adopting the above technical solution, according to the guidance of the guide rod, the extrusion plate can be prevented from tilting during the descending extrusion process.

[0021] Furthermore, a liquid outlet is fixedly connected to one side of the dyeing cylinder, and a valve is fixedly connected to the liquid outlet.

[0022] By adopting the above technical solution, the discharge of liquid can be controlled through the liquid outlet and the valve.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. The present application is provided with a dehydration component. After the dyeing of the loose fibers is completed, the valve can be opened to discharge the internal dyeing liquid from the liquid outlet, and then the dehydration component can be started to descend.

Since the gear 1 82 is meshed with the gear 2 84 and the gear 3 85, when the gear 1 82 rotates, the gear 2 84 and the gear 3 85 will be driven to rotate together. Through the rotation of the gear 2 84 and the gear 3 85, the two rotating rods 86 will continue to rotate, so that the acidic dyeing liquid inside the dyeing cylinder 4 is evenly stirred through the multiple stirring blades 87.

At the same time, during the heating process, the temperature of the liquid inside the dyeing cylinder 4 can be monitored in real time through the infrared sensor 92.

At this time, the hydraulic cylinder 102 is started to descend again to drive the squeezing plate 104 to squeeze the loose fibers and squeeze out the moisture inside the loose fibers, so as to simply dehydrate the dyed loose fibers to prevent the dye attached to the fiber surface from dissolving again, resulting in color difference and color stains. At the same time, it is also convenient for subsequent processing, shortening the subsequent processing time, and greatly improving the practicability of the device.

[0042] The implementation principle of the loose fiber acid dyeing device of the present embodiment is as follows: when in use, first pour the acid dyeing liquid into the dyeing cylinder 4, then place the gauze cage 6 containing the loose fibers on the top of the support plate 5, at this time, the loose fibers inside the gauze cage 6 will gradually absorb the dyeing liquid inside the dyeing cylinder 4 for dyeing, wherein the inside of the loose fibers can be dyed through the central drainage pipe 7, thereby improving the dyeing effect of the device, during the dyeing process, the motor 83 can be started to drive the gear 1 82 to rotate, because the gear 1 82 is meshed with the gear 2 84 and the gear 3 85, so when the gear 1 82 rotates, it will drive the gear 2 84 and the gear 3 85 to rotate together, and through the rotation of the gear 2 84 and the gear 3 85, the two rotating rods 86 will continue to rotate, so that the acid dyeing liquid inside the dyeing cylinder 4 is evenly stirred through a plurality of stirring blades 87, and the continuous stirring of the stirring blades 87 can prevent the pigment precipitation in the internal dyeing liquid, so as not to affect the dyeing effect of the loose fibers;

When the temperature of the liquid is too high, the electric heating wire 91 can be controlled by the controller 3 to lower the temperature to prevent the excessive temperature from affecting the dyeing of the loose fibers inside.
