[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4This utility model provides a technical solution: a pressing device for black tea packaging that prevents material jamming, including a support base 1, a cake-making cylinder 2 and an extrusion frame 3. The cake-making cylinder 2 is connected to one side of the support base 1, and the extrusion frame 3 is provided on the upper side of the cake-making cylinder 2. The bottom of the extrusion frame 3 is connected to one end of a hydraulic push rod 407, and the other end of the hydraulic push rod 407 is connected to the support base 1.

[0024] The inside of the cake-making cylinder 2 is elastically connected to the piston column 4 via a return spring 401. The bottom of the extrusion frame 3 is connected to a threaded connection layer 403, and the bottom of the extrusion frame 3 is threadedly connected to the extrusion filter 402 via the threaded connection layer 403. The extrusion frame 3 has a suction chamber 404 inside. The upper side of the extrusion frame 3 is connected to one end of a suction pipe 405, and the other end of the suction pipe 405 is connected to a vacuum pump 406. One side of the vacuum pump 406 is connected to the extrusion frame 3. The insertion size of the piston column 4 matches the internal size of the cake-making cylinder 2. The support base 1 is connected to a control box 101 inside, and the upper side of the support base 1 is inserted into the extrusion frame 3.

[0025] In practice, to facilitate better shaping of the tea cake, after placing the black tea inside the forming cylinder 2, the hydraulic push rod 407 is activated to move the extrusion frame 3 downwards. This causes the extrusion filter 402 at the bottom of the extrusion frame 3 to push the tea leaves and piston column 4, performing initial extrusion and shaping on the tea leaves. Then, the vacuum pump 406 installed on one side of the extrusion frame 3 is activated. The vacuum pump 406, through the suction chamber 404, suction pipe 405, and extrusion filter 402, cooperates with the piston column 4 at the bottom of the tea leaves to extract excess gas between the tea leaves. At this time, a vacuum zone is formed between the bottom of the extrusion frame 3 and the upper side of the piston column 4. Under the pressure on the lower side of the forming cylinder 2, the piston column 4 moves upwards, cooperating with the extrusion filter 402 to further extrude the tea cake. The tea cake is then subjected to a second extrusion molding process. At this point, the hydraulic push rod 407 is activated again, which drives the extrusion frame 3 to rise. Under the pressure, the piston column 4 continues to move upward until the tea cake is pushed to the upper side of the cake-making cylinder 2, preventing the extruded tea cake from getting stuck inside the cake-making cylinder 2. Furthermore, the extrusion filter 402 is connected to the extrusion frame 3 through the threaded connection layer 403, making it easy to remove, replace, and clean the extrusion filter 402. This anti-jamming tea packaging pressing device achieves secondary extrusion molding of the tea cake through the combination of force extrusion and vacuum negative pressure, resulting in better molding effect. After the tea cake is extruded, it can be pushed to the upper side of the cake-making cylinder 2 for easy removal.

[0026] See Figures 2-4It is known that guide rods 5 are equidistantly connected to the outer side of the piston column 4. The outer sides of multiple guide rods 5 are inserted through the slots inside the cake-making cylinder 2. Positioning slots 501 are symmetrically opened on both sides of the cake-making cylinder 2. Sliding slots 502 and guide slots 506 are symmetrically opened inside the piston column 4. The guide slots 506 are located on both sides of the sliding slots 502. Return springs 503 are connected inside both sliding slots 502. The ends of the two return springs 503 that are far apart are connected to positioning blocks 504. The insertion dimensions of the two positioning blocks 504 are matched with the insertion dimensions of the positioning slots 501. Guide blocks 505 are symmetrically connected to the outer side of both positioning blocks 504. The outer side of the guide blocks 505 is inserted into the guide slots 506.

[0027] In practice, to further facilitate the removal of the tea cake after extrusion molding, when the piston column 4 is continuously pushed upward by pressure, the positioning block 504 at the bottom of the piston column 4 will be fully inserted into the sliding groove 502 under the pushing action of the bottom of the forming cylinder 2. At this time, when the piston column 4 continues to move upward until the positioning block 504 and the positioning groove 501 are on the same plane, the positioning block 504 will be inserted into the positioning groove 501 under the pushing action of the return spring 503 inside the sliding groove 502, limiting the position of the piston column 4. At this time, the operator can easily remove the tea cake. After removing the tea cake, the operator pushes the positioning block 504 along the positioning groove 501. Positioning block 504, until positioning block 504 is completely disengaged from positioning groove 501, piston column 4 can be reset under the action of reset spring 401. The setting of guide block 505 and guide groove 506 can improve the stability of positioning block 504 when moving and limit the range of movement of positioning block 504. The setting of guide rod 5 is used to improve the stability of piston column 4 when moving. This anti-jamming black tea packaging pressing device can stably push the tea cake to the upper side of the cake making cylinder 2 through negative pressure, and the positioning block 504 and positioning groove 501 can make the tea cake quickly and stably removed.

[0028] In summary, when using this anti-jamming black tea packaging pressing device, starting the hydraulic push rod 407 drives the extrusion frame 3 to move downward, which in turn drives the extrusion filter 402 to push the tea leaves and piston column 4 to perform initial extrusion and shaping of the tea leaves. Starting the vacuum suction pump 406, through the extrusion filter 402 and the piston column 4 at the bottom of the tea leaves, extracts excess gas between the tea leaves to form a vacuum zone. Under the pressure on the lower side of the pressing cylinder 2, the piston column 4 moves upward to perform secondary extrusion and shaping of the tea cake, thus completing the pressing process.
