Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing technology, and in particular to a color mixing dyeing vat for fabric printing and dyeing. Background Technology

[0002] In the textile printing and dyeing industry, optimizing the dyeing process is crucial to ensuring uniform fabric color and high dye utilization. In traditional large-scale production, dyeing experiments often require large dye vats, which not only consume large amounts of raw materials (dyes, auxiliaries, water, etc.) but also result in long testing cycles and high costs. Especially for customized production needs involving small batches and multiple varieties, conventional dye vats lack the flexibility to quickly verify process parameters.

[0003] In existing technologies, the design of small dyeing vats for color mixing often focuses on simplifying operation or saving energy, but there are still limitations in controlling the uniformity of the dye liquor. For example, some devices rely solely on unidirectional stirring or simple circulation, resulting in uneven temperature and dye liquor concentration distribution within the vat, affecting the accuracy of experimental results. Utility Model Content

[0004] The purpose of this invention is to provide a dyeing vat for fabric printing and dyeing, which has the function of improving the uniformity of dye liquor in the vat.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dyeing vat for fabric printing and dyeing, comprising a vat body, three dye dispensing devices respectively disposed on the vat body for dispensing red, yellow, and blue dyes, a dye circulation flow device for circulating and transporting the dye solution in the vat body from the bottom to the top, and a dye temperature control device for adjusting the temperature of the dye solution in the vat body to a set range; the dye dispensing device includes a support disposed on the vat body, a dye cylinder disposed on the support body and having a discharge port at the bottom, and a quantity of dye dispensing device disposed at the discharge port of the dye cylinder and dispensing a quantity of dye during rotation. The conveying mechanism includes a buffer chamber located on the side of the cylinder, an inlet pipe located between the buffer chamber and the bottom of the cylinder, a water pump located above the buffer chamber to extract the dye liquor from the buffer chamber, an annular pipe located above the cylinder and having multiple outlet ports arranged in an array at the bottom, and an outlet pipe connecting the outlet of the water pump and the annular pipe. The dye liquor temperature control device includes an electric heating tube located inside the buffer chamber, a temperature sensor located inside the buffer chamber, and a controller located outside the buffer chamber. The controller is connected to the electric heating tube, the temperature sensor, and the water pump via signals.

[0006] By adopting the above technical solution, firstly, the three dye dispensing devices can quantitatively dispense red, yellow, and blue dyes to achieve precise adjustment of the printing and dyeing color; secondly, the dye liquor circulation device can circulate the dye liquor to ensure uniform dispersion of dyes and uniform temperature throughout the dye liquor; in addition, the dye liquor temperature is controlled by heating the dye liquor during the circulation process to maintain the dye liquor at a suitable temperature; finally, it can be applied to small batches of fabrics for precise printing and dyeing color matching.

[0007] A further feature of this invention is that the cylinder is provided with a stirring mechanism to accelerate the flow of dye liquor within the cylinder. The stirring mechanism includes a stirring disc rotatably connected to the bottom of the cylinder and a reduction motor located at the bottom of the cylinder and driving the stirring disc to rotate. The stirring disc is spaced apart from the inner wall of the cylinder, and the stirring disc does not obstruct the connection between the liquid inlet pipe and the cylinder.

[0008] By adopting the above technical solution and setting a drive mechanism to accelerate the water flow in the cylinder, the geared motor can be started intermittently. During the process of the geared motor driving the stirring plate to rotate, the dye liquor is stirred, thereby further improving the uniformity of the dye liquor.

[0009] A further feature of this invention is that the upper surface of the mixing plate is provided with a plurality of drive plates arranged in a circumferential array.

[0010] By adopting the above technical solution, the setting of the drive plate can further improve the stirring effect of the dye liquor, thus enhancing the flow of the dye liquor.

[0011] A further feature of this invention is that a metal mesh cover is provided inside the cylinder to cover the connection port between the liquid inlet pipe and the cylinder body.

[0012] By adopting the above technical solution, the metal mesh cover can cover the connection port of the liquid inlet pipe and the cylinder body to prevent the cloth from clogging the connection port of the liquid inlet pipe and the cylinder body.

[0013] A further feature of this invention is that the quantitative conveying mechanism includes a rotating shaft rotatably connected to the outlet of the dye cylinder and having a feeding trough on its periphery, and a servo motor disposed on the outside of the dye cylinder and linked with the rotating shaft.

[0014] By adopting the above technical solution, the dye falls into the dispensing tank after falling. When the dispensing tank rotates to the bottom as the servo motor drives the rotating shaft, the dye falls out, thereby realizing the quantitative addition of dye.

[0015] A further feature of this invention is that a collection pipe is provided between the outlets of the three dye cylinders to achieve centralized output of multiple dyes.

[0016] By adopting the above technical solution, the collection pipeline can connect the outlets of the three dye cylinders to achieve centralized output of multiple dyes. Attached Figure Description

A collection pipe 24 is also provided between the outlets of the three dye cylinders 22 to centrally discharge multiple dyes.

[0024] like Figure 1 and Figure 3As shown, the dye liquor circulation device 3 includes a buffer chamber 31 disposed on the side of the cylinder 1, an inlet pipe 32 disposed between the buffer chamber 31 and the bottom of the cylinder 1, a water pump 33 disposed above the buffer chamber and for extracting the dye liquor from the buffer chamber 31, an annular pipe 34 disposed above the cylinder 1 and having multiple outlet ports arranged in an array at the bottom, and an outlet pipe 35 connecting the outlet end of the water pump 33 and the annular pipe 34.

[0025] like Figure 1 and Figure 3 As shown, the dye liquor temperature control device 4 includes an electric heating tube 41 installed in the buffer chamber 31, a temperature sensor 42 installed in the buffer chamber 31, and a controller 43 installed outside the buffer chamber 31. The controller 43 is connected to the electric heating tube 41, the temperature sensor 42, and the water pump 33 respectively.

[0026] like Figure 1 and Figure 3 As shown, a stirring mechanism 5 is installed inside the cylinder 1 to accelerate the flow of dye solution within the cylinder 1. The stirring mechanism 5 includes a stirring disc 51 rotatably connected to the bottom of the cylinder 1, and a reduction motor 52 located at the bottom of the cylinder 1 and driving the stirring disc 51 to rotate. The stirring disc 51 is spaced apart from the inner wall of the cylinder 1, and the stirring disc 51 does not obstruct the connection port between the inlet pipe 32 and the cylinder 1. Multiple drive plates 53 arranged in a circumferential array are provided on the upper surface of the stirring disc 51. A metal mesh cover 6 is installed inside the cylinder 1 to cover the connection port between the inlet pipe 32 and the cylinder 1.
