[0002] As people's pursuit of a healthy lifestyle and their increasing understanding of traditional Chinese herbal medicine, Chinese herbal ingredients are mixed with milk tea ingredients to form Chinese herbal milk tea drinks. Chinese herbal milk tea is an innovative product that combines traditional Chinese herbal medicine with modern beverage culture.

[0003] In the process of crushing, some Chinese herbal medicines may not be completely crushed. Incompletely crushed Chinese herbal medicines may have larger particles. If they are mixed into milk tea products, it will affect the taste. If the size difference of the raw material particles is too large, during the mixing process, small particles will gather around the large particles, resulting in uneven mixing. At the same time, the existing Chinese herbal milk tea preform production raw material mixing device uses a stirring rod to stir during the stirring and mixing process, so that a large amount of Chinese herbal milk tea preform production raw materials are attached to the inner cavity of the reactor. At the same time, after the mixing is completed, the staff needs to open the cover again and take it out through tools, which is a complicated step, thereby delaying the mixing workflow of the Chinese herbal milk tea.

[0024] The opening and closing assembly also includes a sliding rod 28 fixedly connected to the side wall of the sliding U-shaped block 27, and the end of the sliding rod 28 away from the sliding U-shaped block 27 is set as an inclined surface. The sliding U-shaped block 27 is symmetrically provided with sliding openings 29, and the sliding openings 29 are provided with no less than two. The end of the connecting rod 1 24 away from the semi-arc plate 1 22 is slidably adapted to one of the sliding openings 29, and the end of the connecting rod 25 away from the semi-arc plate 23 is slidably adapted to the other sliding opening 29. The sliding U-shaped block 27 and the fixed frame 26 are symmetrically fixedly connected with spring extensions. The retractable rod 2 30, the spring telescopic rod 1 9 and the spring telescopic rod 2 30 are all composed of a spring, a sleeve and a movable rod, and the movable rod is slidably adapted to the sleeve, and the two ends of the spring are respectively fixedly connected to the inner cavity of the sleeve and one end of the movable rod located in the sleeve, the elastic force of the strong spring 16 is greater than the elastic force of the spring telescopic rod 1 9, and no less than two spring telescopic rods 2 30 are arranged, and the side wall of the circular plate 4 is fixedly connected with a connecting rod 3 31, the sliding rod 28 is located on the movement path of the connecting rod 3 31, and the bottom of the fixed shell 1 is fixedly connected with a collecting bin 2 32.

[0025] The above implementation works as follows: The initialization steps are as follows: the spring telescopic rod 1 9 is not compressed, the strong spring 16 is not compressed, the semi-arc plate 1 22 and the semi-arc plate 2 23 are on the same horizontal plane, and the spring telescopic rod 2 30 is not compressed.

[0026] The working steps are as follows: The screening component working steps are as follows: The staff pours the Chinese herbal raw materials into the feed pipe 5, and then the Chinese herbal raw materials enter the inner cavity of the piston 6 from the feed pipe 5. At the same time, the Chinese herbal raw materials fall on the upper surface of the conical filter plate 7, so that the Chinese herbal raw materials continue to roll along the curved surface of the conical filter plate 7. The finer Chinese herbal raw materials enter the inner tank 13 through the holes and grooves of the conical filter plate 7, and the coarser Chinese herbal raw materials gather near the connection between the conical filter plate 7 and the notch 8.

[0027] The setting of the screening component can effectively remove larger particles of Chinese herbal raw materials, thereby avoiding the situation where larger Chinese herbal raw materials are difficult to mix with milk tea raw materials. At the same time, the particle size of the Chinese herbal raw materials entering the mixing device is relatively uniform, which is conducive to better dispersion and uniform mixing in the process of mixing Chinese herbal medicine and milk tea.

[0028] The working steps of the stirring and collecting components are as follows: The electric push rod 3 is energized to push the circular plate 4 vertically downward, so the circular plate 4 drives the piston 6 to slide in the inner cavity of the liner 13. Because the outer side of the piston 6 contacts the inner cavity of the liner 13, the lower surface of the piston 6 that moves downward first contacts the arc-shaped protrusion 15, and the lower surface of the piston 6 first squeezes the arc-shaped protrusion 15 to rotate on the notch 14 in the direction close to the inclined plate 17, and the strong spring 16 is stretched by the rotating arc-shaped protrusion 15, and the piston 6 continues to move vertically downward. When the lower surface of the piston 6 no longer contacts the arc-shaped protrusion 15, the arc-shaped protrusion 15 is at the lowest point in the vertical direction. The arc-shaped protrusion 15 is pulled by the elastic contraction force of the strong spring 16, and the arc-shaped protrusion 15 rotates on the notch 14 in the direction away from the inclined plate 17. Therefore, when the arc-shaped protrusion 11 contacts the arc-shaped protrusion 15, the force is mutual. When the arc-shaped protrusion 15 is in the state of being pushed upward by the reverse force of the arc-shaped protrusion 15, the arc-shaped protrusion 11 drives the arc-shaped baffle plate 10 to compress the spring telescopic rod 9 and slide on the notch 8. When the arc-shaped protrusion 11 contacts the top of the inner cavity of the notch 8, the electric push rod 3 no longer extends, and the notch 18 and the notch 2 14 overlap with each other. At this time, the motor 12 is energized, and the motor 12 drives the inner tank 13 to start rotating. The inner tank 13 drives the sliding column 20 to start rotating with the sliding column 20 itself as the axis. Therefore, the sliding column 20 drives the circular sleeve 19 to rotate synchronously, and the circular sleeve 19 drives the conical filter plate 7 to rotate on the piston 6. Therefore, the continuous rotation of the conical filter plate 7 will gather the coarser Chinese herbal medicine raw materials near the connection between the conical filter plate 7 and the notch 8 and throw them into the notch 8. The coarser Chinese herbal medicine raw materials are thrown into the inclined plate 17 and then roll down to the inside of the collection bin 18.

[0029] The electric push rod 3 pushes the piston 6 to continue to move vertically downward. When the arc-shaped protrusion 11 contacts the top of the inner cavity of the notch 8, the arc-shaped protrusion 11 is limited by the top of the inner cavity of the notch 8, so that the arc-shaped protrusion 11 squeezes the arc-shaped protrusion 2 15 and rotates on the notch 2 14 in the direction close to the inclined plate 17. At this time, the compressed spring telescopic rod 19 pushes the arc-shaped baffle 10 vertically downward through the elastic extension force, and the arc-shaped baffle 10 slides vertically downward on the groove of the piston 6, so that the arc-shaped baffle 10 covers the notch 8 again, and the staff puts the milk tea raw materials into the feeding pipe 5 again, and falls on the conical filter plate 7. At this time, the conical filter plate 7 continues to rotate, so that the milk tea raw materials falling on the conical filter plate 7 are broken up by the rotating conical filter plate 7, thereby avoiding the agglomerated milk tea raw materials from being well mixed with the Chinese herbal medicine, so the milk tea raw materials are mixed with the screened Chinese herbal medicine raw materials.

[0030] The coordinated arrangement of the collecting component and the stirring component enables the larger particles of Chinese herbal raw materials to be collected, thereby recycling the larger particles of Chinese herbal raw materials for reuse, reducing the company's raw material procurement costs and avoiding the waste of resources caused by direct discard.

[0031] The working steps of the opening and closing components are as follows: When the piston 6 continues to move downward, the circular plate 4 drives the connecting rod 31 to move vertically downward. Since the sliding rod 28 is located on the movement path of the connecting rod 31, as the piston 6 continues to move downward, the bottom of the connecting rod 31 hits the inclined surface of the sliding rod 28 away from the fixed frame 26. Therefore, the connecting rod 31 pushes the sliding rod 28 to move in the direction close to the fixed frame 26. At this time, the sliding rod 28 pushes the sliding U-shaped block 27 to move in the direction away from the spring telescopic rod 230. The sliding U-shaped block 27 stretches the spring telescopic rod 230, and the sliding U-shaped block 27 passes through the two sliding openings. 29 moves the connecting rod 1 24 and the connecting rod 2 25, so that the connecting rod 1 24 rotates counterclockwise with the connection between the connecting rod 1 24 and the rotating shaft 1 2101 as the axis, and the connecting rod 2 25 rotates clockwise with the connection between the connecting rod 2 25 and the rotating shaft 2 2102 as the axis, so that the semi-arc plate 1 22 and the semi-arc plate 2 23 both swing toward the direction close to the collecting bin 2 32, so the circular hole 21 and the collecting bin 2 32 are connected to each other, and at the same time, the continuous downward movement of the piston 6 also makes the pressure in the inner cavity of the inner liner 13 continue to increase, so the mixed Chinese herbal milk tea raw materials enter the collecting bin 2 32 through the circular hole 21.

[0032] When it is no longer necessary to collect the mixed Chinese herbal milk tea ingredients, the circular plate 4 drives the piston 6 to move vertically upward, and the connecting rod three 31 no longer conflicts with the sliding rod 28. At this time, the stretched spring telescopic rod two 30 moves the sliding U-shaped block 27 in the direction close to the spring telescopic rod two 30 through the elastic contraction force. Therefore, the connecting rod one 24 rotates clockwise with the connection between the connecting rod one 24 and the rotating shaft one 2101 as the axis, and the connecting rod two 25 rotates counterclockwise with the connection between the connecting rod two 25 and the rotating shaft two 2102 as the axis, so that the semi-arc plate one 22 and the semi-arc plate two 23 both swing in the direction away from the collection bin two 32, so that the semi-arc plate one 22 and the semi-arc plate two 23 cover the circular hole 21.

[0033] The setting of the opening and closing components allows the Chinese herbal milk tea mixture to be taken out directly after the mixing is completed, avoiding the complicated steps of the staff opening the lid again and taking it out with tools, simplifying the operation steps of Chinese herbal milk tea mixing, and thus speeding up the workflow of Chinese herbal milk tea mixing.

[0034] Through the cooperation of the piston 6, the electric push rod 3 and the stirring assembly, the inner wall of the inner pot 13 can be scraped by the piston 6 continuously moving downward, thereby preventing the residue of the Chinese herbal milk tea from adhering to the inner wall of the inner pot 13, avoiding the adhesion of the residue of the Chinese herbal milk tea caused by traditional spiral stirring, and saving the step of requiring staff to clean the equipment regularly.
