[0002] Printing and dyeing, also known as dyeing and finishing, is a processing method and a general term for pretreatment, dyeing, printing, finishing, washing, etc. There are two main methods of fabric printing and dyeing: one is traditional pigment printing and dyeing, and the other is reactive printing and dyeing, which is the opposite of pigment printing and dyeing. Fabric printing and dyeing is a wet processing process. When processing printed and dyed fabrics, dyes need to be prepared and the dyes are adjusted through a color matching device.

[0003] Utility model patent CN222064934U discloses a color-matching device for printed and dyed fabrics. This device includes a base plate and a mixing tank. A pad is provided on the base plate, and the mixing tank for stirring dye is mounted on the pad. A water receiving tray is located at the bottom of the base plate, and a support plate is located outside the water receiving tray. A sliding groove is formed on the support plate, and a movable plate is slidably arranged inside the sliding groove. Multiple cylindrical tubes for injecting raw materials are arranged on the movable plate, and pistons are installed inside the cylindrical tubes. Push rods are mounted on the pistons. The multiple cylindrical tubes on the movable plate facilitate the injection of different color-matching materials, simplifying the dye-matching process. The rotating stirring rod stirs the mixed dye in the mixing tank, accelerating the color-matching speed and ensuring more uniform mixing of the dye, thus guaranteeing the processing efficiency of the printed and dyed fabrics.

[0004] In the device disclosed in the above utility model, the cylindrical cylinder relies on manually pressing the fixing block to push the piston to inject dye. Although there are scale lines, differences in operating force can easily lead to deviations in the injection amount, affecting the accuracy of color matching. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency color matching device for fabric printing and dyeing, so as to solve the problem mentioned in the background art that the difference in manual operation force can easily lead to the deviation of injection volume and affect the accuracy of color matching.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4A high-efficiency fabric dyeing and color matching device includes an L-shaped mounting frame 1, a mixing tank 2 mounted on the L-shaped mounting frame 1, a cover plate 3 mounted on the mixing tank 2, a plurality of cylindrical holes 6 on the cover plate 3, and a high-precision dye injection system 4 and a mixing system 5 integrated on the cover plate 3. The high-precision dye injection system 4 includes multiple metering pumps 41, each metering pump 41 being fixed in the cylindrical holes 6 of the cover plate 3 by flanges, and its outlet being connected to the inner cavity of the mixing tank 2 by a hose. An electric push rod 42 is connected to the top of the metering pump 41, and a piston 43 is connected to the moving end of the electric push rod 42. The piston 43 is located in the cavity of the metering pump 41, and a pressure sensor is integrated at the end of the electric push rod 42. A flow sensor is installed in the outlet pipe of the metering pump 41 near the inlet of the mixing tank 2. The pressure sensor, flow sensor, metering pump 41, electric push rod 42 and mixing system 5 are all integrated in a control box 7, which is mounted on the L-shaped mounting frame 1.

[0018] In operation, the operator sets the single injection volume of various dyes via the control box 7. Upon receiving the command, the metering pump 41 controls the electric push rod 42 to precisely push the piston 43, injecting a specific amount of dye into the mixing tank 2. This is complemented by real-time data feedback from the flow sensor, resulting in high-precision dye injection. The mixing system 5 then rapidly and evenly mixes the dye within the mixing tank 2. This high-precision dye injection system achieves highly accurate and automated dye injection, avoiding the injection volume deviations present in manual operations in existing technologies, and further improving the accuracy of dye color matching.

[0019] Specifically, in this embodiment, the stirring system 5 includes a variable frequency motor 51 and multi-stage stirring blades 52. The variable frequency motor 51 is fixed to the outside of the cover plate 3 and connected to a rotating rod 53 via a coupling. The multi-stage stirring blades 52 are installed at the bottom of the rotating rod 53 and extend into the inner cavity of the stirring tank 2. By operating the variable frequency motor 51, the rotating rod 53 drives the multi-stage stirring blades 52 to rotate, thereby driving the dye flow in the stirring tank 2, thus achieving the purpose of rapid dye stirring.

[0020] Specifically, in this embodiment, the multi-stage stirring blades 52 consist of a spiral blade, a shear blade, and an anchor scraper from top to bottom. When the multi-stage stirring blades 52 rotate, the upper spiral blade lifts the liquid to form a vortex, the middle shear blade enhances the dye shearing force, and the lower anchor scraper is close to the barrel wall to prevent the dye in the stirring barrel 2 from settling at the bottom.

[0021] Specifically, in this embodiment, the L-shaped mounting bracket 1 is provided with a lifting mechanism 8, and the cover plate 3 is linked with the lifting mechanism 8 so that when the lifting mechanism 8 is running, it can drive the cover plate 3 to move up and down in the vertical direction, thereby realizing the height adjustment of the cover plate 3 and the stirring system 5 provided on the cover plate 3, so as to facilitate the addition of liquid into the stirring tank 2.

[0022] Specifically, in this embodiment, a sealing gasket is provided at the connection between the cover plate 3 and the mixing tank 2, and a pressure sensor 9 is provided on the top of the cover plate 3. The pressure sensor 9 and the lifting mechanism 8 are electrically connected to the control box 7, so that the pressure sensor 9 can detect the pressure on the cover plate 3 in real time and feed the detection data back to the power component of the lifting mechanism 8. When the detection value reaches the set range, the lifting mechanism 8 is triggered to stop running, thereby achieving the purpose of tightly covering the cover plate 3 on the mixing tank 2 and preventing the liquid in the mixing tank 2 from overflowing during the mixing operation.

[0023] Specifically, in this embodiment, the bottom of the mixing tank 2 is arc-shaped, and a drain outlet 10 is provided at its bottom end. The drain outlet 10 is controlled by a solenoid valve to discharge the liquid in the mixing tank 2 through the bottom drain outlet 10, so as to realize the quantitative discharge of the solution.

[0024] Specifically, in this embodiment, the control box 7 integrates a touch screen and a PLC controller, which can programmatically set the injection sequence of the metering pump 41, the single injection volume, and the speed curve of the variable frequency motor 51, and display the monitoring data of the flow sensor and pressure sensor in real time.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
