Description

Technical Field

[0001] This application belongs to the technical field of dyeing machines, and particularly relates to a water-saving dyeing machine and its control method. Background Art

[0002] In the textile industry, fabric dyeing is a crucial process. It is not only a key step in endowing fabrics with colors and patterns, but also directly related to the final quality and market competitiveness of products. Although existing fabric dyeing machines have made certain progress in automation and mechanization.

[0003] However, under the advocacy of environmental protection and resource conservation, the process of water-saving dyeing is being increasingly developed. Usually, dyeing tubes are set on the dyeing machine, and water-saving dyeing is achieved by reducing the immersion space of fabric dyeing. However, for fabrics of different dyes and materials, the required immersion time is different, and improvements are made in this regard. Summary of the Invention

[0004] The purpose of this application is to provide a water-saving dyeing machine and its control method for the above-mentioned existing technical problems, which can adjust the time when the fabric is immersed in the dye liquor according to the fabric material and the dye liquor material.

[0005] This application provides a water-saving dyeing machine, including a dyeing machine body, and the dyeing machine body includes:

[0006] A dyeing tube, installed on the dyeing machine body, and one end of the dyeing tube is provided with a nozzle;

[0007] A fabric guiding roller, installed on the dyeing machine body and close to the nozzle;

[0008] A conveying device, installed inside the dyeing machine body and located below the dyeing tube, and the conveying device is used to pick up the fabric falling from the dyeing tube and convey it;

[0009] A liquid storage tank, connected to the lower end of the dyeing machine body, and the liquid storage tank is connected to the nozzle through a pump body;

[0010] A first adjusting mechanism, installed between the dyeing tube and the dyeing machine body, and the first adjusting mechanism is used to adjust the inclination of the dyeing tube;

[0011] A second adjusting mechanism, used to adjust the angle between the nozzle and the axis of the dyeing tube;

[0012] Wherein, the liquid storage tank is connected with a control valve for supplementing the dye liquor.

[0013] The fabric passes through the dyeing tube. The dye liquor is sprayed from the nozzle onto the fabric, and the excess dye liquor flows into the dyeing tube. When the fabric moves in the dyeing tube, the fabric is immersed in the dye liquor to continue the dyeing process. The guide cloth roller is connected to a driving device such as a motor, enabling the guide cloth roller to rotate to move and lift the fabric to correspond to the nozzle, facilitating the movement of the fabric in the dyeing tube. The conveying device is connected to a driving device such as a motor, and the fabric placed below the dyeing tube is driven to move through the conveying device, enabling the fabric to move in a cycle. When the fabric moves out of the dyeing tube and falls onto the conveying device, some dye liquor will drip from the dyeing tube. The liquid storage tank collects the dye liquor in the dyeing machine body that is not in the dyeing tube, facilitating the delivery of the dye liquor to the nozzle and improving the utilization rate of the dye liquor. When the fabric is continuously dyed, the dye liquor in the dyeing machine body will be continuously consumed. The control valve can be used to supplement the dye liquor into the liquid storage tank. According to different fabric materials and different dye liquor materials, the required immersion time for dyeing is different. The first adjustment mechanism can adjust the inclination angle of the main axis of the dyeing tube, so that the accumulated dye liquor in the dyeing tube is different, providing applicability for different fabrics and different dye liquors. Although the immersion time can also be adjusted by controlling the moving speed of the fabric, there is a risk of breakage when the moving speed of the fabric is relatively fast. When the main axis of the dyeing tube is horizontal, the immersion time is the shortest. When the inclination angle of the main axis of the dyeing tube increases, the dye liquor in the dyeing tube continues to increase, increasing the effective immersion time of the fabric. After the first adjustment mechanism controls the rotation of the dyeing tube for adjustment, the second adjustment mechanism adjusts the angle between the nozzle and the axis of the dyeing tube, so that the axis of the nozzle remains vertical, enabling the fabric falling from the guide cloth roller to be received more stably.

[0018] The mounting plate and the dyeing tube are connected through fasteners such as bolts, nuts or clamps. The mounting plate is hinged to the dyeing machine body, enabling the dyeing tube to rotate around the hinge axis of the mounting plate and the dyeing machine body. The driving cylinder is driven by a power source such as electricity, hydraulics or pneumatics to provide the power device for the rotation of the mounting plate and the dyeing tube. The buffer support part is installed between the driving cylinder and the mounting plate. When the fabric moves, the force change and fluctuation relative to the support tube are stabilized through the buffer support part, improving the stability of the installation structure of the dyeing tube.

After the mounting base and the movable column are installed, the support columns abut against the movable column.

[0029] Further, the movable column includes:

[0030] A cover body, connected to the movable column through fasteners;

[0032] Wherein, the mandrel is provided with a threaded portion, the movable column is provided with a threaded hole corresponding to the threaded portion, and the movable column is provided with a locknut adapted to the threaded portion.

[0033] The connection between the mandrel and the movable column is facilitated through the mounting cavity, and the connection stability between the mandrel and the movable column is improved through the simultaneous cooperation of the threaded hole and the locknut with the threaded portion for threaded connection. After installation, the mounting cavity is closed by the cover body, the cover body and the movable column are connected through fasteners such as bolts, and the cover body and the output shaft of the driving cylinder are connected through fasteners such as bolts.

[0063] Next, the embodiments of the present application will be described in detail with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0064] Embodiment 1:

[0065] As Figure 1 shown, an embodiment of the present application provides a water-saving dyeing machine, including a dyeing machine body 100, and the dyeing machine body 100 includes:

[0066] A dyeing tube 110 is installed on the dyeing machine body 100, and a nozzle 111 is provided at one end of the dyeing tube 110;

[0067] A cloth guiding roller 200 is installed on the dyeing machine body 100 and is close to the nozzle 111;

[0068] A conveying device 300 is installed inside the dyeing machine body 100 and is located below the dyeing tube 110. The conveying device 300 is used to pick up the cloth falling from the dyeing tube 110 and convey it;

[0069] A liquid storage tank 120 is connected to the lower end of the dyeing machine body 100, and the liquid storage tank 120 is connected to the nozzle 111 through a pump body;

[0070] A first adjusting mechanism 400 is installed between the dyeing tube 110 and the dyeing machine body 100, and the first adjusting mechanism 400 is used to adjust the inclination of the dyeing tube 110;

[0071] A second adjusting mechanism 500 is used to adjust the angle between the nozzle 111 and the axis of the dyeing tube 110;

[0072] Among them, the liquid storage tank 120 is connected with a control valve for supplementing the dyeing solution.

[0073] The fabric passes through the dyeing tube 110, and the dyeing solution is sprayed from the nozzle 111 onto the fabric. The excess dyeing solution flows into the dyeing tube 110. When the fabric moves in the dyeing tube 110, the fabric is immersed in the dyeing solution to continue dyeing. By connecting the guide roller 200 to a driving device such as a motor, the guide roller 200 can rotate to move and lift the fabric to correspond to the nozzle 111, facilitating the movement of the fabric in the dyeing tube 110. The conveying device 300 is connected to a driving device such as a motor, and the fabric placed below the dyeing tube 110 is driven to move through the conveying device 300, enabling the fabric to move in a cycle. When the fabric moves out of the dyeing tube 110 and falls onto the conveying device 300, some dyeing solution will drip from the dyeing tube 110. The liquid storage tank 120 collects the dyeing solution in the dyeing machine body 100 that is not in the dyeing tube 110, facilitating the delivery of the dyeing solution to the nozzle 111 and improving the utilization rate of the dyeing solution. When the fabric is continuously dyed, the dyeing solution in the dyeing machine body 100 will be continuously consumed. The control valve can control the supplement of the dyeing solution into the liquid storage tank 120. According to different fabric materials and different dyeing solution materials, the soaking time required for dyeing is different. The first adjusting mechanism 400 can adjust the inclination angle of the main axis of the dyeing tube 110, so that the accumulated dyeing solution in the dyeing tube 110 is different, providing applicability for different fabrics and different dyeing solutions. Although the soaking time can also be adjusted by controlling the moving speed of the fabric, there is a risk of breakage when the moving speed of the fabric is relatively fast. When the main axis of the dyeing tube 110 is horizontal, the soaking time is the shortest. When the inclination angle of the main axis of the dyeing tube 110 increases, the dyeing solution in the dyeing tube 110 continues to increase, increasing the effective soaking time of the fabric. After the first adjusting mechanism 400 controls the rotation and adjustment of the dyeing tube 110, the second adjusting mechanism 500 adjusts the angle between the nozzle 111 and the axis of the dyeing tube 110, so that the axis of the nozzle 111 remains vertical, and the fabric falling from the guide roller 200 can be received more stably.

The support column body 432 and the core shaft 434 are connected by a connecting rod 436 to realize the simultaneous telescoping of the support column bodies 432, improving the stability between the mounting base 431 and the movable column 440.
