With the increasing demand for efficiency, environmental protection and energy saving in the textile industry, the design of dyeing machines is also being continuously optimized.

[0003] A micro high-temperature and high-pressure dyeing machine is disclosed in Chinese Patent No. CN222613717U, which belongs to the technical field of dyeing machines. The high-temperature and high-pressure dyeing machine comprises a cylinder, a cover, a cloth guide device, a cloth guide pipe and a transport nozzle. The cylinder comprises a first section and a second section connected together. The first section and the second section are of an integrated structure. The first section and the second section are arranged at an angle. The cylinder is arranged with the tail of the second section upward. The cover is arranged at the port of the second section away from the first section. The cloth guide device is arranged inside the end of the second section away from the first section.

[0047] The implementation principle of the dye solution circulating device of the dyeing machine according to the embodiment of the application is as follows: the dye solution enters the recycling box 100 through the liquid inlet pipe 110 and passes through the first filter plate 200, so as to reduce the impurities in the dye solution. The filtered dye solution is recycled into the body of the dyeing machine through the liquid outlet pipe 120, so as to reduce the impurities in the body of the dyeing machine, improve the dyeing effect, and improve the product quality. When the dye solution passes through the first filter plate 200, the first motor 430 drives the screw rod 410 to rotate, so as to drive the sliding block 420 to move along the length direction of the first filter plate 200. The scraper 300 moves with the sliding block 420, so as to push the impurities and make the impurities accumulate at the lowest part of the first filter plate 200, so as to facilitate the collection of the impurities and reduce the situation that the impurities block the first filter plate 200.
