Description

Technical Field

[0001] This utility model belongs to the field of dyeing experimental technology in the textile industry, and specifically relates to an injection-type precision dyeing device. Background Technology

[0002] In the textile industry, dyeing is a crucial step in fabric production. Before use, dyeing sizing agents often require dyeing experiments, and the amount of sizing agent added is a critical parameter in the dyeing process. Current technology typically requires a combination of equipment, such as a small-scale dyeing machine, a sample dyeing instrument, a dyeing machine, a small-scale dyeing machine, a ribbon dyeing machine, or an integrated dyeing machine, to complete the dyeing experiment. Furthermore, these types of equipment commonly use peristaltic pumps to add the dyeing sizing agent to control the amount added. However, the flexible tubing of peristaltic pumps is prone to loosening and aging over long-term deformation, resulting in poor durability and stability. Additionally, peristaltic pumps suffer from a common problem: the faster the injection speed, the greater the deviation in control precision, making it difficult to meet the high-precision dyeing and sampling requirements of laboratory settings.

[0003] Therefore, it is necessary to design an injection-type precision dyeing device that can achieve precise control of the dyeing slurry injection volume and does not use a peristaltic pump. Utility Model Content

The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0030] like Figures 1 to 5As shown, this embodiment designs an injection-type precision dyeing device, including an injection mechanism 2, a three-way connector 7, a first one-way valve 6, a second one-way valve 8, a stirring mechanism 3, a dye tank 4, a cabinet 1, and other components.

[0031] The stirring mechanism 3 has multiple components arranged in a row; the stirring mechanism 3 includes a stirring cylinder 33, a stirrer 39, and a mesh cylinder 35; the mesh cylinder 35 is located outside the stirrer 39 and rotates with the stirrer 39, and the mesh cylinder 35 is used to place the fabric sample; the stirrer 39 is driven by a stirring motor 38.

[0032] The stirring motor 38 is connected to the stirrer 39 via a magnetic coupling. The magnetic coupling includes a first magnet 36 and a second magnet 37. The second magnet 37 is fixedly connected to the rotating shaft of the stirring motor 38, and the first magnet 36 is fixedly connected to the stirrer 39.

[0033] The upper end of the stirrer 39 is provided with a limiting disk 310, which can abut against the inner wall of the stirring cylinder 33 to limit the swing of the upper end of the stirrer 39.

[0034] The stirring drum 33 is detachably mounted on the mounting base 32. The mounting base 32 has a heat exchange chamber 34 inside its wall. The heat exchange chamber 34 is connected to a temperature-controlled water source to facilitate temperature control of the dyeing slurry inside the stirring drum 33.

[0035] The top of the mixing drum 33 is provided with a cover plate 31. The pipe between the tee connector 7 and the mixing drum 33 passes through the cover plate 31 and is inserted into the mixing drum 33. A drain pipe is also provided on the cover plate 31, with one end inserted into the mixing drum 33 and the other end connected to a negative pressure source. The negative pressure source can be a pump structure or a vacuum tank. A balancing vent can be provided on the cover plate 31 to balance the air pressure between the mixing drum 33 and the atmospheric environment.

[0036] The injection mechanism 2 has multiple components; the relationship between the stirring mechanism 3 and the injection mechanism 2 is one-to-one, one-to-two, or one-to-many; the injection mechanism 2 includes a syringe 23, an injection seat 21, a piston seat 22, and an injection motor 25; the empty cylinder of the syringe 23 is fixedly connected to the injection seat 21, the piston of the syringe 23 is fixedly connected to the piston seat 22, and the piston seat 22 can move under the drive of the injection motor 25.

[0037] The injection seat 21 is provided with a slide rail, and a slide table is provided on the slide rail. The slide table is fixedly connected to the piston seat 22. The shaft of the injection motor 25 is connected to a lead screw 24, and the lead screw 24 is threadedly engaged with the slide table.

[0038] The three ports of the three-way connector 7 are respectively connected to the dye tank 4, the syringe 23 and the stirring cylinder 33; a first one-way valve 6 is provided on the pipe between the three-way connector 7 and the dye tank 4, and a second one-way valve 8 is provided on the pipe between the three-way connector 7 and the stirring cylinder 33. The syringe 23 can draw the dyeing slurry in the dye tank 4 and inject it into the stirring cylinder 33.

[0039] The cabinet 1 is in the shape of a two-step step. Several mounting bases 32 are set on the step surface of the cabinet 1. The mounting bases 32 are arranged in a U-shape. Each mounting base 32 corresponds to a stirring cylinder 33, so that the stirring cylinder 33 can be put into the mounting base 32. The stirring motor 38 is set at the bottom of the mounting base 32. Each of the stirring cylinders can be independently removed from the mounting base 32.

[0040] Several observation windows, multiple sets of external connectors, a dye placement chamber 11, a display screen, and switches are provided on the kick surface of cabinet 1. The observation windows are directly opposite the syringe 23, allowing operators to view the amount of dye slurry injected by the syringe 23. A movable door is provided at the front opening of the dye placement chamber 11. The dye placement chamber 11 is used for placing and removing dye tanks 4, and one or more dye tanks 4 can be placed inside. Each set of external connectors has multiple connectors; the pipes connected to the mixing drum 33 are connected to the cabinet 1 through corresponding external connectors. Operators can connect the external connectors to the mixing drum 33 as needed, facilitating the addition and mixing of the dye slurry.

[0041] When using the injection-type precision staining device in this solution:

[0042] Place the stirrer 39 and the mesh cylinder 35 into the stirring cylinder 33, and place the fabric sample into the mesh cylinder 35. After closing the cover plate 31, the stirring cylinder 33 can be placed into the mounting cylinder base. When the first magnet 36 and the second magnet 37 achieve mutual magnetic attraction, the stirring motor 38 starts and can control the rotation of the stirrer 39.

[0043] The experimenter needs to insert one end of different pipes into the cover plate 31 and the other end into the external connector, so that the stirring tank 33 is connected to the tee connector 7 and the negative pressure source through different pipes. When dyeing experiments with different dye addition amounts are required, the injection motor 25 rotates and controls the piston of the syringe 23 to move downward, thereby using the syringe 23 to draw the dye slurry in the dye tank 4. During this process, the dye slurry enters the main pipeline 5 through the pipe, then flows into the branch pipeline, and enters the syringe 23 after passing through the first one-way valve 6. When adding dye, the injection motor 25 rotates in the opposite direction and controls the piston of the syringe 23 to move upward, thereby injecting the dye slurry drawn by the syringe 23 into the stirring tank 33 through the second one-way valve 8.

[0044] Similarly, when different dye slurries need to be mixed in the same mixing drum 33, different injection mechanisms 2 can be used to draw dyeing slurries from different dye tanks 4 for injection. After dyeing is completed, the dyeing slurries in the mixing drum 33 can be discharged using a negative pressure source.

[0045] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
