Description

Technical Field

[0001] This utility model relates to the field of solution-dyed fiber production technology, specifically to a solution-dyed fiber production equipment. Background Technology

[0002] Solution-dyed fiber is a type of colored chemical fiber produced by directly adding colorants (such as pigments, masterbatches, or color pastes) to the spinning solution or melt, and then simultaneously spinning and coloring. It is also known as undyed fiber or pre-spinning dyed fiber. Solution-dyed fiber (also known as colored spun fiber) is a technology that adds colorants directly to the spinning melt or solution before spinning. Compared with traditional post-dyeing processes, it has advantages such as water saving, energy saving, and reduced pollution.

[0003] Existing production equipment mostly relies on personnel to add a fixed amount of dye and solution into the tank for mixing and spinning. This production method is prone to color difference, affecting the consistency of fiber quality. At the same time, the static mixing or low-speed stirring used in traditional production can easily cause pigment agglomeration, resulting in color spots or uneven strength in the fiber. Therefore, we propose a solution-dyed fiber production equipment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a solution-dyed fiber production equipment. It achieves high-precision quantitative addition of dye through the coordinated control of electric telescopic rod, distance sensor and flow valve to greatly reduce color difference. At the same time, it adopts a planetary dynamic mixing system to improve the uniformity of pigment dispersion to avoid color spot problem, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a solution-dyed fiber production equipment, comprising a material tank and a metering unit;

[0007] Quantitative unit: includes a liquid outlet pipe, a dye box, and a locking block. The liquid outlet pipe is connected to the left side of the dye box and is inserted into the through hole on the right side of the material tank. The locking block is fixed to the side of the dye box and is engaged with the locking groove on the surface of the fixing frame.

[0008] The system also includes a controller, which is fixed to the surface of the tank. The input of the liquid pump is electrically connected to the output of the controller, and the input of the controller is electrically connected to the output of an external power source.

The input end of the electric telescopic rod is electrically connected to the output end of the controller. Activating the electric telescopic rod causes the push plate to rise, adding a quantitative amount of dye solution into the tank. The observation window, along with the scale, allows personnel to easily check the remaining amount.

[0011] Furthermore, the quantitative unit also includes a distance sensor and a flow valve. The distance sensor is fixed to the bottom surface inside the dye box, and the flow valve is installed at the end of the inlet pipe.
