Description

Technical Field

[0001] This utility model belongs to the field of dye cup position adjustment, specifically relating to a supercritical carbon dioxide anhydrous dyeing cup capping device. Background Technology

[0002] When using carbon dioxide mixed dyes to dye fabrics, it is necessary to adjust the dyeing effect and ratio of the dyes. At this time, it is necessary to use a dye cup to conduct small-scale dyeing tests. For example, the patent application number 2024206576451 of our company is called a double-groove sampling dye cup. The dye cup is a high-pressure container used to hold sampling samples and fill them with carbon dioxide for dyeing. It consists of a cup body, a cup lid, and components such as an inflation and exhaust port.

[0003] The lid of the dyeing cup needs to be tightened during use to press the sealing ring. Since the dyeing cup is a high-pressure container, the tightening force is relatively large. In the past, manually tightening the lid was laborious and the force was uneven. If the tightening force is too small, the seal will not be tight, and if the tightening force is too large, the threads may seize up. Utility Model Content

[0004] To address the force issue in the tightening process of existing dye cups, this application designs a supercritical carbon dioxide anhydrous dyeing cup capping device, aiming to achieve fine control of the tightening force of the dye cup cap through the mechanical control of the screwing device.

[0016] The top of the connecting shaft is connected to the output shaft of the servo motor;

[0017] The bottom of the connecting shaft is connected to the clamp;

[0018] The clamp is located at the upper end of the support on the dye cup.

[0019] Preferably, a speed reduction mechanism is also connected between the servo motor and the connecting shaft.

[0020] Preferably, the connecting shaft is a cylinder, and the bottom of the connecting shaft is provided with two symmetrical straight-edge grooves, with the top of the clamp nested in the bottom groove of the connecting shaft.

[0021] Preferably, the clamp includes an end plate, a side clamping plate, and an intermediate connecting plate;

[0022] The end plate is positioned above the intermediate connecting plate;

[0023] The end plate is nested in the bottom groove of the connecting shaft;

[0045] Furthermore, the fixing device includes an upper support for the dye cup 2, a lower support for the dye cup 3, and a clamping mechanism;

[0046] The lower support 3 of the dye cup is located below the upper support 2 of the dye cup; the distance between the upper support 2 of the dye cup and the lower support 3 of the dye cup is equal to the distance between the retaining rings of the dye cup.

[0047] The clamping mechanism includes a cylinder assembly 4 and a clamping block 5; the cylinder assembly 4 is used to connect to the clamping block 5 and control the movement of the clamping block 5, thereby driving the clamping block to clamp the dye cup to achieve the fixation of the dye cup.
