s1, a first die assembly driver 63 drives a cover plate 62 away from an opening 611, and a feeder 5 transmits tea leaves in the container 1 to the interiors of a first cylinder 61 and a second cylinder 64 through the opening 611;

s2, the first die assembly driver 63 drives the cover plate 62 to be close to the first cylinder 61 and is embedded with the opening 611;

s3, a cake pressing driver 69 drives the male die 68 to move towards the base 66, and tea leaves in the first cylinder 61 and the second cylinder 64 are pressed into tea cakes;

s4, a cake pressing driver 69 drives a male die 68 to reset, a second die closing driver 65 drives a second cylinder 64 to descend, the base 66 does not move, and tea cakes are exposed on the outer side of the female die;

s5, taking out the tea cake, and driving the second cylinder 64 to reset by the second die assembly driver 65.

Further: the first clamp actuator 63 and the press cake actuator 69 are servo cylinders.

The reason why the first mold closing driver 63 uses a servo cylinder instead of the cylinder or the hydraulic cylinder is that: after the cover 62 is fitted into the opening 611, the first mold clamping driver 63 needs a self-locking function so that the cover 62 does not move away from the opening 611 when pressing a cake.

The reason why the cookie driver 69 uses a servo cylinder instead of a cylinder or a hydraulic cylinder is that: the tea leaves need to be pressed slowly and at a constant speed so as not to be broken in the process of pressing cakes, and different tea leaves need to be pressed into tea cakes with different thicknesses, and the distance between the male die 68 and the base 66 needs to be adjusted at any time.

Alternatively, as shown in fig. 11, 16, 17:

when the first cylinder 61 is arranged vertically, it is also necessary to be guided to enter the inside of the opening 611 from the side after the tea leaves are taken out of the container 1 by the feeder 5.

The cover plate 62 is slidably connected to the first chute 67, the first chute 67 extends along the second direction, one end of the first chute 67 is located at the output end of the blanking device 5, the other end of the first chute 67 extends to the opening 611, and the cross-sectional shape of the first chute 67 is identical to the shape of the opening 611.

The tea leaves are pushed down from the interior of the container 1 by the fourth driver 52 and fall into the interior of the first chute 67 by the blanking push plate 51, and the cover plate 62 and the first mold closing driver 63 constitute a pushing device for pushing the tea leaves to move inside the first chute 67, and the tea leaves are pushed into the interior of the first cylinder 61 from the opening 611 through the first chute 67 and then fall onto the base 66.

Alternatively, as shown in fig. 11 and 19:

in order to avoid shaking of the tea cake on the base 66 during lifting of the second cylinder 64 by the second clamp actuator 65.

The base 66 is provided with a locating boss 661 on a side thereof adjacent the mould cavity.

After pressing the cake, one end of the tea cake is provided with a recess which is matched with the positioning protrusion 661, so that the tea cake is not easy to shake when the second cylinder 64 moves.

Further, as shown in fig. 14:

the male die 68 has a concave surface 681 at a position inside the die cavity, and the concave surface 681 is a spherical surface.

The concave surface 681 is used for compensating the problem of uneven quality of the tea cake caused by the positioning protrusion 661, so that the thickness of each place of the tea cake is basically the same.

Alternatively, as shown in fig. 9, 12-15, 19:

in general, the workpiece is easy to adhere to the male die, in the related art, the workpiece is ejected through the ejector pins arranged on the ejector pin plate, but because the cake is pressed by loose tea leaves into a compact tea cake, the stroke of the male die 68 is long, and the male die 68 is reset for a long distance to enable the ejector pin plate to be abutted against the die carrier.

And the tea cake is different from the workpiece, and in the process that the tea cake moves along with the male die 68 until the ejector pin is bumped, the side wall of the tea cake rubs with the side wall of the first barrel 61, so that the edge of the tea cake is easily broken, and the moving distance of the tea cake along with the male die 68 needs to be shortened.

In order to solve the above problems, the male die 68 and the execution part of the cookie pressing driver 69 are connected by a bracket 70, a fifth driver 71 is fixedly mounted on the bracket 70, the fifth driver 71 comprises an execution part capable of moving along the central line of the first cylinder 61, a cookie jacking head 72 is embedded on one surface of the male die 68 close to the die cavity, the cookie jacking head 72 is in transmission connection with the execution part of the fifth driver 71, and the fifth driver 71 is used for driving the cookie jacking head 72 to move so as to eject a cookie adhered on the male die 68.

Specifically, the fifth driver 71 is a pushing cylinder, and in the process of resetting the male die 68 driven by the cake pressing driver 69, the fifth driver 71 drives the cake pushing head 72 to push down the tea cake adhered to the concave surface 681.

Further, as shown in fig. 14:

the side of the cookie head 72 that is inside the mold cavity is the same shape as the concave surface 681.

Further:

the cake top 72 is in a conical shape or a step shaft shape, the size of one end of the cake top 72 close to the male die 68 is smaller than that of the other end of the cake top 72, and when the cake top 72 is abutted against the male die 68, one surface of the cake top 72 positioned inside the die cavity is smoothly connected with the concave surface 681.

Further, as shown in fig. 12-14:

because the size of the cookie head 72 is small, it cannot withstand a large force, and if the cookie head 72 is fixedly connected to the actuator of the fifth driver 71, the fifth driver 71 repeatedly pulls the cookie head 72 to collide with the male die 68, which easily causes the cookie head 72 to be broken.

In order to solve the above problem, the top cake head 72 is slidably connected to the male die 68 through a slide post 73, an annular flange 731 extending radially outwards is formed at one end of the slide post 73 away from the top cake head 72, a spring 74 is mounted on the slide post 73, and both ends of the spring 74 are respectively abutted against the male die 68 and the annular flange 731.

The fifth driver 71 is only used for driving the cake ejection head 72 to eject the tea cake, the cake ejection head 72 is reset by the resilience force of the spring 74, and the elasticity force of the spring 74 is smaller than the pulling force of the fifth driver 71.

Alternatively, as shown in fig. 10, 11, 15, 18, 19:

a sixth driver 75 is provided beside the base 66, the sixth driver 75 having an execution part moving toward the base 66 along the second direction, a pancake turner 76 is fixedly mounted on the execution part of the sixth driver 75, and the sixth driver 75 is used for driving the pancake turner 76 to turnup a pancake on the base 66.

Specifically, the sixth driver 75 is an air cylinder, the base 66 is provided with a second chute 77 in a direction away from the sixth driver 75, and the cake shovel 76 scoops up and pushes the tea cake on the base 66 into the second chute 77, and the tea cake is transferred to the dryer through the second chute 77.

Alternatively, as shown in fig. 20:

the airflow generator 8 includes an airflow nozzle 81 and a seventh driver 82;

the air flow nozzle 81 can output air flow with the same shape as the inner cavity of the first hopper 11;

the seventh driver 82 has an actuator moving along the center line of the first hopper 11, and the actuator of the seventh driver 82 is fixedly connected to the air jet head 81.

The seventh driver 82 is a cylinder sliding table, and the seventh driver 82 is used for driving the air flow nozzle 81 to vertically lift, so that the air flow output by the air flow nozzle 81 can blow through each part of the inner cavity of the first hopper 11 from top to bottom.

Further:

the air jet 81 is used to output high-pressure high-temperature steam.

The air flow nozzle 81 shares a steam generator with the steam nozzle 31, and the high-temperature and high-pressure steam is more capable of softening tea leaves than compressed air, so that the tea leaves are more easily blown off.

Further, as shown in fig. 21:

the air flow nozzle 81 includes a nozzle 811 and a baffle 812;

the nozzle 811 is disposed downward and flares outward in a horn shape;

a baffle plate 812 is fixedly connected to the nozzle 811 and is positioned below the nozzle 811, and a gap is provided between the nozzle 811 and the baffle plate 812 so that the air flow transmitted through the nozzle 811 forms an air knife.

The nozzles 811 serve to guide the air flow to be downwardly transferred and spread obliquely toward the periphery, and the baffles 812 serve to block the air flow transferred only downwardly while allowing the air flow to form an air knife, thereby allowing the air flow to be completely blown to the inner wall of the first hopper 11, reducing unnecessary air flow, and increasing the flow rate of the air.

Alternatively, as shown in fig. 20:

below the air jet 81 is arranged a waste bin 83 below the container 1.

The waste bin 83 is used to collect tea leaves remaining in the container 1.
