[0021] A method for extracting tea pigments for tea processing comprises the following steps:

[0022] S1, start the electric push rod to seal the bottom end of the first filter plate, add water, start the motor to drive the crushing roller to rotate to crush the tea leaves;

[0023] S2, the crushing roller rotates and drives the stirring shaft to stir and clean the tea leaves;

[0024] S3. After cleaning, start the electric push rod to release water, close the electromagnetic clutch, lower the material receiving frame to the second filter plate, use the stirring shaft to push the tea leaves to the material receiving frame, start the electric push rod to seal again, add water, and continue crushing and cleaning;

[0025] S4. After the soaking is completed, the electric push rod is started to release water, and the liquid is filtered through the third filter plate and then discharged. The electromagnetic clutch is started to lift the material receiving frame and the tea leaves are discharged through the first push plate.

[0026] In the present application, first, the electric push rod is started to drive the first blocking plate to move upward, sealing the bottom end of the first filter plate, and an appropriate amount of water is added. The motor is then started to drive the crushing roller to rotate, and tea leaves are put in for crushing, so that the crushed tea leaves fall into the first filter plate;

[0027] Secondly, the rotation of the crushing roller can drive the stirring shaft to rotate through the synchronous wheel and the synchronous belt. The rotation of the stirring shaft can drive multiple stirring spoons to rotate to stir and clean the tea leaves;

[0028] When the cleaning is completed, the electric push rod is started to retract and drive the first blocking plate to move downward, releasing the seal on the bottom end of the first filter plate. At this time, the cleaning water in the first filter plate is discharged through the first blocking plate and the first drain port, and the electromagnetic clutch is closed, and the material receiving frame falls on the second filter plate under the action of gravity. At this time, the top of the material receiving frame is flush with the top of one side of the first filter plate, and the motor is continued to be started to drive the stirring shaft to rotate. During the rotation of the stirring shaft, the tea leaves in the first filter plate can be pushed into the material receiving frame through the stripping plate until the tea leaves in the first filter plate are completely pushed into the material receiving frame. Then the electric push rod is started again to move upward to drive the first blocking plate to move upward. When the first blocking plate moves upward, it can drive the second blocking plate to move upward, and at the same time, seal the bottom ends of the first and second filter plates, and drive the wedge block to move upward through the extension plate. The upward movement of the wedge block can drive the two extension frames to move away from each other, which can drive the second clamping ring to engage with the first clamping ring, add an appropriate amount of boiling water in the material receiving frame for soaking and extraction, the crushing roller continues to crush the tea leaves and clean them in the first filter plate;

[0029] During the rotation of the crushing roller, the rotating shaft can be driven by the synchronous wheel and the synchronous belt. The rotation of the rotating shaft can drive the second clamping ring to rotate. The rotation of the second clamping ring can drive the sleeve rod to rotate through the first clamping ring. The rotation of the sleeve rod can drive the cam to rotate. During the rotation of the cam, one end of the pull rope can be driven to move up and down, which can drive the receiving frame to move up and down on the second filter plate, so that the tea leaves are soaked back and forth in the boiling water.

[0030] After the soaking and extraction is completed, the electric push rod is started to drive the first blocking plate and the second blocking plate to move downward, releasing the bottom seal of the first filter plate and the second filter plate to drain water, and the extracted liquid is filtered through the third filter plate and discharged through the second drain outlet, and the electromagnetic clutch is started. At this time, the rotation of the rotating shaft can drive the output end of the electromagnetic clutch to rotate, which can drive the winding roller to rotate through the synchronous wheel and the synchronous belt to retract one end of the pull rope, which can drive the material receiving frame to move upward. When the material receiving frame hits the first push plate, it continues to move upward to drive the spring rod to rotate on the first rotating seat, and drive the spring rod to retract and retract, and drive the first push plate to move on the bottom wall of the material receiving frame. During the movement, the tea leaves on the material receiving frame can be pushed to one side. When the material receiving frame corresponds to the discharge port, the tea leaves are discharged from the discharge port.

[0031] During the rotation of the stirring shaft, it can also drive the second rotating bar to rotate. The rotation of the second rotating bar can drive the sliding bar to move back and forth on one side of the extraction box through the first rotating bar and the connecting bar. The movement of the sliding bar can drive the sliding block to move in the rectangular hole. During the movement, it drives the second push plate to move on the third filter plate, which can clean the impurities on the second push plate, make the impurities fall on the guide plate, and be flushed away by the cleaning water in the first filter plate.

[0032] Beneficial effects:

[0033] In the present invention, the tea pigment extraction device for tea processing can not only drive the crushing roller to rotate and crush the tea leaves by starting the motor, but also drive the stirring spoon on the stirring shaft to rotate and stir the tea leaves, thereby improving the cleaning effect. In addition, when the first blocking plate drives the extension plate to move downward, the tea leaves in the first filter plate can be pushed into the receiving frame through the material stripping plate, eliminating the need for manual cleaning, making it more convenient to use and cleaner to clean.

[0034] In the present invention, the tea pigment extraction device for tea processing is characterized in that, by connecting the first blocking plate with the second blocking plate, the bottoms of the first filter plate and the second filter plate can be simultaneously sealed and opened during the process of starting the electric push rod to extend and retract, thereby facilitating water storage and drainage. In addition, a wedge is arranged on the first blocking plate, so that the second clamping ring can be driven to engage with the first clamping ring during the process of sealing the first filter plate and the second filter plate, thereby driving the tea leaves to move back and forth in the water during the extraction process, and the water flow can drive the tea leaves to be turned over, thereby improving the soaking efficiency.

[0035] In the present invention, the tea pigment extraction device for tea processing is used in conjunction with a pull rope and a winding roller, so that the winding roller can receive the pull rope during rotation, drive the receiving frame to move upward, and cooperate with the first push plates on the two spring rods to clean out the tea leaves in the receiving frame during the movement, eliminating the need for manual cleaning and unloading, thereby improving processing efficiency.

[0036] In the present invention, the tea pigment extraction device for tea processing, by arranging the second push plate on the third filter plate, can drive the second push plate to move back and forth on the third filter plate during the rotation of the stirring shaft, can simultaneously clean impurities on multiple third filter plates, and the cleaned impurities can be flushed out of the extraction box using the cleaning water in the first filter plate, can effectively keep the third filter plate clean, and avoid clogging of the third filter plate, which affects the filtering effect;

[0037] In the present invention, by starting the motor, not only the crushing roller can be driven to crush the tea leaves, but also the stirring shaft can be driven to stir and clean the tea leaves. The cleaning can transfer the tea leaves for tea pigment extraction. After the extraction is completed, the extract can be automatically filtered, and the tea leaves on the material frame can be automatically cleaned. There is no need for manual transfer and cleaning, which can improve processing efficiency and is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
