Existing cleaning methods are limited and cannot thoroughly clean the inside of the mixing equipment, leaving residues that affect the mixing effect. Furthermore, traditional dye stirring equipment is typically single-function, only capable of stirring, and cannot monitor changes in dye viscosity in real time, making it difficult to precisely control the stirring effect and impacting dye quality. Utility Model Content

A stirring drive mechanism is installed on the outside of the dye container assembly and transmits power to the stirring shaft through a transmission mechanism; It also includes a lifting mechanism, a cleaning mechanism, a viscosity sensor, and a torque sensor; The lifting mechanism connects to and drives the stirring drive mechanism to move up and down. The cleaning mechanism includes a spray cleaning component, a first pipe, a first reversing valve, an air inlet pipe, a second pipe, a second reversing valve, and a cleaning agent inlet pipe. The spray cleaning component is installed inside the dye container assembly and is connected to the outlet of the first reversing valve through the first pipe. The inlet of the first reversing valve is connected to both the air inlet pipe and the outlet of the second pipe. The inlet of the second pipe is connected to the outlet of the second reversing valve. The inlet of the second reversing valve is connected to both the water inlet pipe and the cleaning machine inlet pipe.

A viscosity sensor is installed inside the dye container assembly to detect the viscosity of the dye; a torque sensor is installed between the stirring drive mechanism and the stirring shaft to detect the torque during the stirring process.

[0005] Furthermore, the lifting mechanism includes a lead screw and a sliding seat. The lead screw is vertically mounted on the frame above the dye container assembly and is driven by a motor. The sliding seat is threadedly engaged with the lead screw and can slide up and down along the lead screw. The stirring drive mechanism is mounted on the sliding seat to drive the stirring shaft and the stirrer to move in the vertical direction.

[0006] A dye mixing device for printing on wine box packaging also includes a control system electrically connected to the stirring drive mechanism, the lifting mechanism, the viscosity sensor, and the torque sensor, for controlling the operation of the equipment and controlling the rotational speed of the stirring shaft based on the data detected by the sensors.

[0007] Furthermore, it also includes an ultrasonic level sensor, mounted on a flange on top of the dye container assembly and electrically connected to the control system, for detecting the level of the dye.

[0017] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.

[0018] Example See Figure 1 The dye mixing device of this utility model mainly includes a frame, a dye container assembly 1, a stirring shaft 2, a stirrer 5, a stirring drive mechanism 3, a dye feed pipe, a lifting mechanism 4, a cleaning mechanism, a viscosity sensor 7, a torque sensor 9, and a control system.

[0019] The dye container assembly 1 is installed at the bottom of the frame and includes a main container and a top cover. The main container is a cylindrical container used to hold dye, and it has an external jacket layer for temperature control. Its outer wall has mounting holes and connection ports for installing other components and connecting pipes. A drain pipe is located at the bottom. See [link / details omitted] Figure 2 The stirring shaft 2 is vertically positioned at the center of the dye container assembly 1, with its lower end connected to the stirrer 5 and its upper end connected to the stirring drive mechanism 3. Driven by the stirring drive mechanism 3, the stirring shaft 2 rotates, causing the stirrer 5 to stir the dye. The stirrer 5 is installed at the lower end of the stirring shaft 2 and extends into the dye container assembly 1. The stirring drive mechanism 3 transmits power to the stirring shaft 2 through a transmission mechanism 31, enabling the stirring shaft 2 to rotate. It uses a power source such as a motor and is equipped with a corresponding reducer or other transmission device to adjust the stirring speed. The transmission mechanism 31 uses belt drive, where the driving pulley is connected to the motor output shaft, and the driven pulley is connected to the stirring shaft 2 through a torque sensor 9.

[0020] See Figure 1The lifting mechanism 4 includes a lead screw 41 and a sliding seat 42. The lead screw 41 is vertically mounted on the frame above the dye container assembly 1 and is driven by a motor. The sliding seat 42 is threadedly engaged with the lead screw 41 and can slide up and down along the lead screw 41. The stirring drive mechanism 3 is mounted on the sliding seat 42. Through the action of the lifting mechanism 4, the stirring drive mechanism 3 and the stirring shaft 2 can move vertically. It can also be moved upwards to the outside of the dye container assembly 1 for quick replacement of the stirrer 5. Furthermore, it can adjust the position of the stirrer 5 inside the dye container.

[0021] See Figure 2 The type of agitator 5 can be selected according to the properties of the dye and the stirring requirements. Common types include paddle agitators, anchor agitators, or turbine agitators 5. The agitator 5 rotates under the drive of the stirring shaft 2 to stir the dye and make it evenly mixed.

[0022] See Figure 3 The cleaning mechanism includes a spray cleaning assembly 6, a first pipe 61, a first reversing valve 62, an air inlet pipe 63, a second pipe 64, a second reversing valve 65, and a cleaning agent inlet pipe 66. The spray cleaning assembly 6 is disposed within the dye container assembly 1 and includes a spray pipe installed at an upward angle at the lower part of the dye container assembly 1, inclined towards the agitator 5. Multiple staggered nozzles are arranged on the spray pipe. The nozzles can evenly spray cleaning liquid, gas, and cleaning agent onto the inner wall of the container and the agitator 5, achieving cleaning of the container.

[0023] The spray cleaning assembly 6 is connected to the outlet of the first reversing valve 62 via the first pipe 61. The inlet of the first reversing valve 62 is connected to the outlet of the air inlet pipe 63 and the second pipe 64. The inlet of the second pipe 64 is connected to the outlet of the second reversing valve 65. The inlet of the second reversing valve 65 is connected to the water inlet pipe 67 and the cleaning machine liquid inlet pipe. The water inlet pipe 67, the cleaning machine liquid inlet pipe, and the air inlet pipe 63 are connected to the water tank, the cleaning agent tank, and the air compressor, respectively. The second reversing valve 65 controls the switching between clean water and cleaning agent, while the first reversing valve 62 controls the switching between clean water and gas pipelines.

[0024] The water inlet pipe 67 is connected to a water source to provide cleaning water. The first reversing valve 62 and the second reversing valve 65 control the direction and flow rate of the fluid within the pipes. The air inlet pipe 63 is connected to an air source to introduce gas into the cleaning liquid. The cleaning agent inlet pipe 66 is connected to a cleaning agent storage device for adding cleaning agent. During operation, first, the cleaning agent inlet pipe 66 is connected to the second reversing valve 65, allowing the cleaning agent to enter the second pipe 64. Then, the first reversing valve 62 is connected to the second pipe 64, allowing the cleaning agent to enter the first pipe 61 and then the spray cleaning assembly 6. The spray cleaning assembly 6 sprays the cleaning agent onto the dye container assembly 1 through its nozzles for initial cleaning. After the initial cleaning is completed, the second reversing valve 65 is connected to the water inlet pipe 67, allowing clean water to sequentially flow through the second pipe 64, the first reversing valve 62, and the first pipe 61 into the spray cleaning assembly 6 for secondary cleaning of the dye container assembly 1. After the second cleaning is completed, disconnect the connection between the first reversing valve 62 and the second pipe 64, and at the same time connect the first reversing valve 62 and the air inlet pipe 63 so that dry compressed air enters the spray cleaning component 6 through the first pipe 61 to dry the inside of the dye container component 1.

[0025] The first pipe 61, the second pipe 64, the water inlet pipe 67, and the cleaning agent inlet pipe 66 are all equipped with flow regulating valves.

[0026] See Figure 2 The viscosity sensor 7 is installed inside the dye container assembly 1 to detect the viscosity of the dye; the torque sensor 9 is installed between the stirring drive mechanism 3 and the stirring shaft 2 to detect the torque during the stirring process.

[0027] The control system is electrically connected to the stirring drive mechanism 3, the lifting mechanism 4, the viscosity sensor 7, and the torque sensor 9. It controls the operation of the equipment and adjusts the rotational speed of the stirring shaft 2 based on the data detected by the sensors. The viscosity sensor 7 transmits the detected viscosity signal to the control system, which adjusts the operating parameters of the stirring drive mechanism 3 accordingly. The torque sensor 9 transmits the detected torque signal to the control system, which determines whether the stirring process is normal based on the torque signal. If an abnormal torque is detected, timely measures can be taken to prevent equipment damage and production accidents.

[0028] See Figure 2 The device of this invention also includes an ultrasonic level sensor 8, which is installed on the flange at the top of the dye container assembly 1 and electrically connected to the control system for detecting the dye level. The ultrasonic level sensor 8 measures the dye level in the dye container by emitting and receiving ultrasonic signals, and transmits the level signal to the control system so that the control system can monitor the dye level in real time and perform corresponding production scheduling and control.

[0029] In operation, the dye mixing device of this invention first pours the dye to be stirred into the dye container assembly 1. Then, the stirring drive mechanism 3 is activated, which transmits power to the stirring shaft 2 via the transmission mechanism 31, causing the stirrer 5 at the lower end of the stirring shaft 2 to rotate and stir the dye. During the stirring process, the viscosity sensor 7 monitors the viscosity of the dye in real time and transmits the viscosity signal to the control system. The control system automatically adjusts the speed and stirring time of the stirring drive mechanism 3 according to the viscosity signal to ensure that the dye achieves the ideal mixing effect. At the same time, the torque sensor 9 monitors the torque during the stirring process in real time. If the torque exceeds the set value, the control system will issue an alarm and take corresponding measures, such as adjusting the stirring speed or stopping the machine for inspection. After the dye is stirred, the vertical container needs to be cleaned. At this time, the control system controls the lifting mechanism 4 to raise the stirring drive mechanism 3 and the stirring shaft 2 away from the dye container assembly 1, and replaces the stirrer 5. Then, the spray cleaning assembly 6 is turned on, and the first reversing valve 62 and the second reversing valve 65 adjust the flow direction and flow rate of water and gas according to the instructions of the control system. The cleaning and drying process of "cleaning liquid-clean water-gas" is completed sequentially by controlling the first reversing valve 62 and the second reversing valve 65. After cleaning is completed, the spray cleaning component 6 is turned off, and the product can be used again. The quality of the dye ratio for the next application is ensured by replacing the agitator 5 and cleaning it.

Within the scope of knowledge possessed by those skilled in the art, all variations, equivalent substitutions, and improvements made without departing from the concept of the present invention should be included within the protection scope of the present invention.
