[0010] As a further solution of the present invention, the connecting side frame further includes: connecting blocks, the shape of the connecting blocks is a circular block structure, and the number of connecting blocks is set to two, and the connecting blocks are symmetrically and fixedly arranged on one side of the connecting side frame; a detection bracket, the shape of the detection bracket is an L-shaped frame structure, and the detection bracket is fixedly installed in the middle of the bottom of the connecting side frame; a proximity switch, which is fixedly installed at one end of the detection bracket; a cleaning slide, which slides on one side of the connecting side frame.

[0012] The dyeing device for colored spun yarn provided by the present invention has the following beneficial effects: Through the arrangement of the lower pressing roller and the sliding pressing roller, under the elastic action of the spring, the extrusion slider can drive the sliding pressing roller to move downward. This mechanism ensures that the colored spun yarn is subjected to uniform and appropriate pressure, effectively promoting the deep penetration and uniform distribution of the dyeing agent. At the same time, the excess dyeing agent is extruded through the extrusion action, significantly improving the dyeing efficiency and the quality of the finished product, reducing the problems of uneven dyeing or over-dyeing. The continuous extrusion operation of the sliding pressing roller and the lower pressing roller, combined with the dynamic cleaning function of the cleaning slide and the cleaning scraper thereon, further enhances the practicality of the system. The cleaning scraper is closely attached to the surface of the pressing roller under the drive of the spring force. As the pressing roller rotates, it can not only immediately scrape off the residual dyeing agent attached thereto, preventing it from drying and solidifying and affecting the subsequent dyeing effect, but also greatly reduces the equipment pollution and maintenance costs caused by the residual dyeing agent. The cleaning scraper with a conical design not only optimizes the diversion path of the dyeing agent, ensures the smooth discharge of the scraped dyeing agent, reduces the waste of the dyeing agent, but also enhances the cleaning efficiency through its geometric shape and maintains the long-term clean state of the pressing roller.

[0013] In addition, the automatic wear detection mechanism of the cleaning scraper, as the cleaning scraper gradually wears during use, detects the gradual movement of the rear detection frame until the proximity switch is triggered. This process realizes the real-time monitoring of the wear state of the cleaning scraper. Once the proximity switch is activated, it immediately sends a signal to the external control device, triggering the warning mechanism to remind the operator to replace the cleaning scraper in time. This automated monitoring and warning system not only avoids the risk of affecting production efficiency due to excessive wear of the cleaning scraper, but also significantly improves the predictability and convenience of equipment maintenance, ensuring the continuous and stable operation of the production line.

[0032] The specific usage mode and function of this embodiment: During the use of the dyeing device, pour the dyeing agent into the dyeing tank 1 through the liquid inlet hole 103, pass the colored spun yarn through the top of the connecting roller 207 and the bottom of the dyeing roller 205. At this time, by starting the driving air cylinder 202, the driving air cylinder 202 will drive the driving frame 203 to move through the piston rod, so that the driving frame 203 will push the colored spun yarn into the dyeing tank 1 through the dyeing roller 205 for immersion dyeing. During the continuous dyeing process, the driving motor 104 can be used. The driving motor 104 will drive the stirring plate 102 to rotate through the transmission shaft 101. The stirring plate 102 can stir the dyeing agent, thereby preventing precipitation in the dyeing agent and ensuring uniform dyeing of the colored spun yarn.

[0033] During the dyeing process of colored spun yarn, the colored spun yarn passes between the lower pressing roller 301 and the sliding pressing roller 303. The extrusion slider 302 will move downward under the drive of the spring between the connecting side head 304 and the extrusion bracket 3. The extrusion slider 302 will drive the sliding pressing roller 303 to move downward. The sliding pressing roller 303 can apply pressure to the colored spun yarn and extrude the colored spun yarn, so as to squeeze out the dye remaining in the colored spun yarn. When the sliding pressing roller 303 and the lower pressing roller 301 continuously extrude the colored spun yarn, the cleaning slide base 404 will move towards the sliding pressing roller 303 and the lower pressing roller 301 under the drive of the spring between the connecting rear block 405 and the connecting block 401. The cleaning scraper 407 on one side of the cleaning slide base 404 will contact the sliding pressing roller 303 and the lower pressing roller 301. Under the condition that the sliding pressing roller 303 and the lower pressing roller 301 continuously rotate and extrude, the cleaning scraper 407 will scrape off the dye remaining on the sliding pressing roller 303 and the lower pressing roller 301. Moreover, the cleaning scraper 407 is designed in a conical structure, and the dye scraped off by the cleaning scraper 407 will flow out along both sides of the cleaning scraper 407, thereby reducing the loss of dye.

[0034] When the cleaning scraper 407 continuously contacts the sliding pressing roller 303 and the lower pressing roller 301, the cleaning scraper 407 will continuously wear, and then the cleaning scraper 407 will continuously move forward. At this time, the detection rear frame 406 at the rear end of the cleaning slide base 404 will move towards the proximity switch 403. When the cleaning scraper 407 wears to a certain extent, the trigger block 408 on the detection rear frame 406 will contact the proximity switch 403. At this time, the proximity switch 403 will be triggered, and the proximity switch 403 will send a signal to the external control device, and then the external control device will issue a warning, indicating that the cleaning scraper 407 has worn to a certain position and needs to be replaced, so as to judge the wear condition of the cleaning scraper 407.
