Description

Liquid-saving type cloth dyeing device Technical Field The utility model relates to the technical field of textile dyeing equipment, in particular to a liquid-saving type cloth dyeing device. Background Dyeing of cloth is an important process link in the textile industry, and its technical level directly affects product quality, production cost and environmental protection effect. In the conventional dyeing production process of cloth, the cloth needs to be fully soaked in a dyeing tank to be dyed, and then the dyed cloth is led out of the dyeing tank through a guide roller system and is subjected to subsequent treatment. To ensure the dyeing effect, the dyeing liquid generally needs to be kept at a certain concentration and temperature, which makes the cost of the dye in the dyeing tank a considerable proportion of the total production cost. With the increasing strictness of environmental protection requirements and the continuous rising of raw material cost, how to improve the utilization efficiency of dye and reduce the waste of dye has become an important direction of the technical development of dyeing equipment. In the existing cloth dyeing technology, when the cloth is drawn out from the dyeing tank, a large amount of dyeing liquid is carried on the surface and in the fiber gaps due to the porosity and capillary action of the cloth fiber. Of the carried dye solutions, only a part of the dye solutions can be really absorbed by the fabric fibers to form effective coloring, and a considerable part of free dye solutions which are not absorbed by the fibers can be lost in the subsequent processes of extrusion, drying and the like, so that serious dye waste is caused. Some existing dyeing devices are also provided with a simple squeeze roller or a diversion device to recover part of the dye liquor, but the traditional recovery mode has the following technical problems: The extrusion effect is poor and there is a lack of precise control. The traditional extrusion device generally adopts fixed pressure or simple elastic pressure system, can't carry out accurate pressure adjustment according to the cloth characteristic of different thickness, material, and the dyestuff rate of recovery is low when leading to the extrusion inadequately, and the excessive time of extrusion is probably damaged cloth fibre again, influences product quality. In addition, the recovery is not thorough enough, the existing device can only recover most of the extruded dye liquor, and the trace dye liquor still remained on the surface of the cloth after extrusion lacks an effective recovery means, so that the trace dye liquor still causes considerable waste when accumulating in mass production. Therefore, how to realize multistage recovery of dye through reasonable structural design, how to accurately control extrusion pressure to adapt to the processing requirements of different fabrics, how to recover residual dye liquor on the fabric surface to the maximum extent is a technical problem to be solved in the field of current fabric dyeing equipment. Disclosure of utility model Solves the technical problems of serious dye loss, incomplete recovery, poor extrusion effect, lack of accurate control, imperfect recovery of residual dye liquor and the like in the existing cloth dyeing device, and provides a liquid-saving cloth dyeing device capable of realizing multistage recovery of dye, remarkably reducing dye waste and improving dye utilization rate. The technical scheme includes that the liquid-saving type cloth dyeing device comprises a dyeing groove, a pre-liquid-removing guide plate, a squeeze roller set, an auxiliary dye recovery device and a dye collecting system, wherein the pre-liquid-removing guide plate is arranged at a cloth outlet end of the dyeing groove and is provided with a guide inclined surface inclined towards the inside of the dyeing groove, the squeeze roller set is arranged on a cloth travelling path behind the pre-liquid-removing guide plate, the auxiliary dye recovery device is arranged on a cloth travelling path behind the squeeze roller set, and the dye collecting system is arranged below the squeeze roller set and the auxiliary dye recovery device. Preferably, the squeeze roller set comprises an upper squeeze roller and a lower squeeze roller, and further comprises a squeeze pressure adjusting mechanism connected with the upper squeeze roller, wherein the upper squeeze roller adjusts the position relative to the lower squeeze roller through the squeeze pressure adjusting mechanism. Preferably, the auxiliary dye recycling device comprises an elastic scraping plate, and the scraping edge of the elastic scraping plate is attached to the surface of the cloth. Preferably, the auxiliary dye recycling device further comprises a negative pressure liquid suction port, and the negative pressure liquid suction port is connected with a negative pressure source. Preferably, the dye collection system comprises a dye collection
