Description

Multi-cup-cover linkage control device and dyeing machine Technical Field The invention belongs to the technical field of dyeing machines, and particularly relates to a multi-cup-cover linkage control device and a dyeing machine Background In the laboratory proofing and development stage of textiles, dyeing machines are key devices for conducting small-batch dyeing tests on yarns or fabrics. Conventional rotary dyeing machines typically employ a single or multiple independently rotating cylinders, each with a plurality of dye cup locations circumferentially disposed thereon, each dye cup location having an independent cup cover thereon. In order to realize automatic cover opening and closing operation in the dyeing process, the prior art (such as the patent application of application number CN 202220830762.4) generally adopts a mode of independently configuring a linear pushing device (such as a cylinder or an electric push rod) for each cup cover. The control mode of one-to-one can realize the basic uncovering function, but the inherent defects are obvious, namely, firstly, each pushing device needs independent installation space and gas path/circuit connection, so that the occupied space of the whole uncovering mechanism in the rotary cylinder body or around the rotary cylinder body is very large, the structure is bulky and loose, secondly, the space is occupied by a large number of independent executing elements, the number of the dyeing cups which can be arranged on a single rotary cylinder body is severely limited, the flux of the device for processing samples is limited by the physical structure, and the flexibility is insufficient. Along with the improvement of automation level, a full-automatic integrated dyeing device (such as a scheme in patent application number 202311518197.3) integrating dyeing functions with other procedures (such as automatic material cutting and material dripping) appears on the market. In such highly integrated plants, the dyeing module is used as a ring of the entire production chain, and the compactness of the structure is more demanding. However, in the conventional independent cup cover control manner, the huge driving structure is difficult to effectively layout and flexibly increase and decrease the number of dyeing cups in the integrated equipment on the premise of not influencing other functional modules, and is difficult to match the different requirements of different customers on the sample proofing flux. In addition, in certain specific dyeing processes, simultaneous uncapping or uncapping operations for multiple dyeing cups are required to ensure consistency of process conditions. In the prior art, the mode of relying on a plurality of independent drivers can realize approximate synchronization through circuit control, but the risks of different response time of each executive component and difficult absolute synchronization of actions exist, and a control system is complex and high in cost. Therefore, there is a need to fundamentally improve the cup cover opening and closing control mode of the existing dyeing machine, and it is necessary to design a multi-cup cover linkage control mechanism with compact structure and small occupied space, which can synchronously and reliably control the opening and closing of a plurality of cup covers or even all cup covers through one driving source. On the one hand, the space inside the rotary cylinder body can be greatly released, conditions are created for increasing the number of dyeing cups and improving single proofing capability, on the other hand, the inherent synchronous characteristic of the rotary cylinder body can better meet specific process requirements, and meanwhile, the simplified structure of the rotary cylinder body is easier to integrate and expand in integrated dyeing equipment with limited space, so that the overall adaptability and market competitiveness of the equipment are improved. Disclosure of Invention The invention aims to provide a multi-cup-cover linkage control device which comprises a fixing frame, a cup cover mechanism, a cover closing mechanism and a cover opening mechanism, wherein a plurality of or all cup covers are integrated into a whole through the cup cover mechanism, the cover closing mechanism is used for closing the cup covers of dyeing cups, the cover opening mechanism is used for opening the cup covers and removing the opened cup covers above the mouths of the dyeing cups, the cup cover mechanism, the cover closing mechanism and the cover opening mechanism are combined to complete synchronous cover opening and synchronous cover closing operation of the cup covers of the multi-dyeing cups, and after the cover opening of the dyeing cups is ensured, various dyeing procedures can be completed on the dyeing cups. The invention also aims to provide a dyeing machine, wherein the multi-cup-cover linkage control device is applied to the dyeing machine, so that the dyeing machine is comp
