[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea tree. It is also known as tea, tea, tea leaves, and tea. The ingredients of tea include catechins, cholesterone, caffeine, inositol, folic acid, and pantothenic acid, which are good for health. Tea cake is a kind of compressed tea. The tea leaves are compressed into cakes, which are convenient for long-distance transportation and long-term storage. In order to prevent deterioration during transportation, compressed tea is generally made from black tea or dark tea. When you need to drink tea, just knock a piece of the tea cake to make tea soup.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 4 The utility model provides a tea processing extrusion device, including a base 1, wherein vertical rods 2 are fixedly arranged at positions near four corners on the upper surface of the base 1, and sliding sleeves 3 and springs 4 are movably sleeved on the outer walls of the four vertical rods 2, and the two ends of the spring 4 are respectively fixed to the lower surface of the sliding sleeve 3 and the upper surface of the base 1, and mold frames 5 are fixedly arranged at the inner ends of the four sliding sleeves 3. A hydraulic cylinder 7 is fixedly arranged above the base 1 through a bracket 6, and a pressing plate 8 is fixedly arranged at a position where the lower end of the piston rod of the hydraulic cylinder 7 is located just above the mold frame 5, and a vibration component is arranged between the piston rod of the hydraulic cylinder 7 and the mold frame 5, and a baffle 15 is arranged on the lower surface of the mold frame 5 through a locking mechanism.

[0021] In this embodiment, preferably, the vibration assembly includes a mounting plate 10 fixedly mounted on the upper surface of the front and rear two uprights 2, the side walls of the two mounting plates 10 are rotatably connected with a connecting shaft 11, an elliptical wheel 13 is fixedly mounted on the inner end of the connecting shaft 11, and positioning blocks 14 are fixedly mounted on both sides of the mold frame 5 below the elliptical wheel 13. The vibration assembly also includes a rack 9 fixedly mounted on the outer wall of the circumference of the piston rod of the hydraulic cylinder 7 symmetrically, a gear 12 is fixedly mounted on the outer end of the connecting shaft 11, and the two racks 9 are respectively meshed with the two gears 12, and the piston rod of the hydraulic cylinder 7 is extended to drive the two racks 9 to move vertically downward. When the pressing plate 8 moves, the connecting shaft 11 drives the elliptical wheel 13 to rotate through the meshing transmission of the rack 9 and the gear 12. After the elliptical wheel 13 rotates to the position against the positioning block 14, the mold frame 5 is pressed down, and the spring 4 elastically contracts. When the elliptical wheel 13 continues to rotate, the spring 4 rebounds and lifts the mold frame 5 upward. Then, during the downward movement of the pressing plate 8, the mold frame 5 vibrates multiple times, so that the tea leaves in the mold frame 5 are flattened and relatively compacted. When the pressing plate 8 enters the interior of the mold frame 5, the rack 9 is disengaged from the gear 12, and the mold frame 5 stops vibrating to avoid affecting the pressing plate 8 to squeeze the tea leaves.

[0022] In this embodiment, preferably, the locking mechanism includes a rotating shaft 17 connected to the side wall of the baffle 15, and hooks 19 are symmetrically fixed on the front and back of the circumferential outer wall of the rotating shaft 17, and positioning columns 20 are symmetrically fixed on the front and back of the mold frame 5, and the two hooks 19 are movably sleeved on the outside of the two positioning columns 20, and a knob 18 is fixed at the front end of the rotating shaft 17. The locking mechanism fixes the baffle 15 under the mold frame 5. After the tea leaves are squeezed, the worker holds the knob 18 and turns the rotating shaft 17, so that the rotating shaft 17 drives the two hooks 19 to rotate synchronously, and the hooks 19 are turned out from the outside of the two positioning columns 20, so that the baffle 15 and the mold frame 5 can be unlocked, and the baffle 15 and the mold frame 5 can be separated, so as to facilitate the removal of the tea leaves from the mold frame 5.

[0023] In this embodiment, preferably, an array of exhaust holes 16 is opened inside the pressing plate 8, and the top of the baffle 15 is abutted against the lower surface of the mold frame 5. After the pressing plate 8 moves down to the inside of the mold frame 5, when the space between the pressing plate 8 and the baffle 15 in the mold frame 5 is reduced, the air in the space is discharged through the exhaust holes 16.

[0024] In this embodiment, preferably, material trays 21 are fixedly provided symmetrically on the upper surface of the mold frame 5. Both material trays 21 are inclined with the outer side higher and the inner side lower. After pouring the tea leaves onto the inclined surface in the material tray 21, the tea leaves slide along the inclined surface to the inside of the mold frame 5, which is convenient for loading.

[0025] The working principle and use process of the utility model are as follows: when the device is used, the device is connected to an external power source, and after the tea leaves are poured onto the inclined surface in the material tray 21, the tea leaves slide down the inclined surface to the inside of the mold frame 5, and then the piston rod of the hydraulic cylinder 7 is extended to drive the two racks 9 and the pressing plate 8 to move vertically downward, and the meshing transmission between the rack 9 and the gear 12 makes the connecting shaft 11 drive the elliptical wheel 13 to rotate, and after the elliptical wheel 13 rotates to the position against the positioning block 14, the mold frame 5 is pressed down, and the spring 4 elastically contracts. When the elliptical wheel 13 continues to rotate, the spring 4 rebounds to lift the mold frame 5 upward, and then During the downward movement of the pressing plate 8, the mold frame 5 vibrates several times, so that the tea leaves in the mold frame 5 are flattened and relatively compacted. When the pressing plate 8 enters the interior of the mold frame 5, the rack 9 and the gear 12 are disengaged, and the mold frame 5 stops vibrating. After the pressing plate 8 cooperates with the baffle 15 to squeeze the tea leaves in the mold frame 5, the knob 18 is held and the shaft 17 is turned, so that the shaft 17 drives the two hooks 19 to rotate synchronously, and the hooks 19 are turned out from the outside of the two positioning columns 20, so that the baffle 15 and the mold frame 5 can be unlocked, the baffle 15 and the mold frame 5 can be separated, and then the tea leaves can be taken out of the mold frame 5.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
