[0047] The driving mechanism is used to provide power for the movable plate 2 to move.

[0048] Among them, the driving mechanism consists of two parts: one part provides power for the up and down movement of the movable plate, which can be achieved by a cylinder or a stepper motor; the other part uses a servo motor to control the forward and backward movement of the push plate. Since the positioning accuracy required for the forward and backward movement is very high, a servo motor is selected.

[0049] Preferably, the tea steaming trough 1 is provided with a plurality of tea scraping structures 12 , and the tea scraping structures 12 are used to remove tea leaves on the pushing plate 14 .

[0050] The tea scraping structure 12 may be an airflow generating structure that removes tea leaves on the pushing plate 14 by blowing air or the like.

[0051] Preferably, at least one steam cavity is provided on the wall of the tea steaming trough 1, the steam hole 11 is connected to the steam cavity, the steam cavity is connected to a steam pipe 13, and the steam pipe 13 is used to connect to a steam generating device.

[0055] like Figure 1 , Figure 2 and Figure 6 As shown, the present invention also provides a multi-station tea cake pressing machine, characterized in that it includes the tea steaming device and also includes:

[0056] A main hopper 3, which is used to discharge materials from its discharge port at a predetermined speed;

[0057] The spiral vibrator 4 has a weighing hopper 15 at its discharge port, which is used to receive the discharge from the main hopper 3 and transport it to the weighing hopper 15;

[0058] A buffer hopper 5, which is used to receive tea leaves in the weighing hopper 15 for transporting to one end of the tea steamer;

[0059] a mold cavity 6, which is arranged at the other end of the tea steamer to receive tea leaves discharged from the tea steamer;

[0060] The cake pressing mold 7 is movably arranged in the mold cavity 6, and is used for pressing the tea leaves in the mold cavity 6 into cakes.

[0061] Preferably, a tea inlet 8 is provided on the mold cavity 6 , and the shape and size of the tea inlet 8 are consistent with the shape and size of the arc-shaped push plate 14 .

[0062] Preferably, a stirring rod 9 is rotatably installed in the main hopper 3;

[0063] The discharge port of the main hopper 3 is movably provided with a discharge gate 10 and a vibrator 16 , and the discharge gate 10 and the vibrator 16 are both used to adjust the discharge speed of the discharge port of the main hopper 3 .

[0064] Preferably, the spiral vibrator 4 is provided with a material level sensor, and the material level sensor is used to detect the height of tea leaves at the feeding port of the spiral vibrator 4 and control the start and stop of the vibrator 16 .

[0065] Preferably, the weighing hopper 15 and the spiral vibrator 4 are installed independently of each other, and there is a gap between them.

[0066] Preferably, when the number of the weighing hoppers 15 is greater than the number of the buffer hoppers 5 , at least one of the weighing hoppers 15 is capable of feeding materials to the buffer hopper 5 on either side.

[0067] Example 1

[0068] 1) Set the number of tea steamers to 2, the number of main hoppers 3, spiral vibrators 4, weighing hoppers 15, and buffer hoppers 5 to 3.

[0069] 2) Put loose tea into the main hopper 3 manually or automatically, and the stirring rod 9 of the main hopper 3 rotates slowly to break up the tea leaves to prevent the tea leaves from being piled up and accumulated in the main hopper 3. The vibrator 16 on the main hopper 3 vibrates to evenly send the tea leaves out of the discharge port. The discharge speed of the tea leaves is controlled by adjusting the amplitude of the vibrator 16 and the opening and closing angle of the discharge door 16 of the main hopper 3.

[0070] 3) After the tea leaves are discharged from the main hopper 3, they enter the spiral vibrator 4. Each outlet of the main hopper 3 corresponds to a spiral vibrator 3. A material level sensor can be installed to control the material level height above the spiral vibrator 3 and control the start and stop of the vibrator 16.

[0071] 4. Tea leaves are transported to the weighing hopper 15 in an orderly manner through the spiral groove of the spiral vibrator 3; each spiral vibrator 3 corresponds to a weighing hopper 15; a weighing sensor is set on the weighing hopper 15, so that the start and stop of the spiral vibrator 4 can be controlled by setting the target weight of the weighing sensor. Figure 1In the figure, the weighing hoppers are named weighing hopper 1, weighing hopper 2, and weighing hopper 3 from left to right; weighing hopper 1 and weighing hopper 3 are the main working hoppers. When the weight of the materials in the two weighing hoppers reaches the set weight, the hoppers open and discharge the materials; weighing hopper 2 is an auxiliary hopper. When the materials in weighing hopper 1 and weighing hopper 3 cannot reach the predetermined weight within the set time, the weighed materials in weighing hopper 2 are used to supplement the material gaps, so as to avoid the whole machine stopping to wait for a hopper to weigh materials. Therefore, weighing hopper 2 can be opened in both directions. The left material plate can be opened to replace the materials in weighing hopper 1, and the right material plate can be opened to replace the materials in weighing hopper 3.

[0072] 5. After the material is weighed, it enters the buffer hopper 5. When there is material in both buffer hoppers 5, the two buffer hoppers 4 are opened at the same time and the material is discharged into the steam tank.

[0073] 6. The steam tank is evenly divided into five sections by four sets of pusher plates 14. The first section is a material receiving station for accommodating tea leaves discharged from the buffer hopper. The second to fourth sections are tea steaming stations. There are micropores of 0.5-2 mm at the bottom of these three sections, which are steam holes 11.

[0074] 7. Pass steam to the steam pipe 13;

[0075] 8. All the push plates 14 move forward one section at the same time to complete the feeding process into the mold cavity 6;

[0076] 9. The arc-shaped plate withdraws from the mold cavity 6, and the four flat plates withdraw to a position in contact with the tea scraping structure 12;

[0077] 10. The push plate 14 is lifted upwards, and at the same time, the push plate 14 rubs against the tea scraping structure 12 on the steam tank 1, so that the tea leaves that may be stuck to the push plate 14 are scraped off and fall back into the steam tank 1. The wet tea leaves may stick to the push plate 14;

[0078] 11. The pushing plate 14 retreats and falls to the starting position, completing a tea delivery process;

[0079] 12. After the tea leaves are fed into the mold cavity 6, the upper mold in the cake pressing mold 7 presses down and scrapes off the tea leaves that may be stuck on the curved plate, and together with the lower mold in the cake pressing mold 7, presses the tea leaves into shape.

[0080] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
