[0030] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0031] Please refer to the attached drawing, which is a structural schematic diagram of a preferred embodiment of a multi-row linkage pressing mechanism and a tea production device provided by the utility model.

[0032] A multi-row linkage pressing mechanism, comprising: a first pressing device and a second pressing device arranged in an array, the first pressing device comprising a cylinder 2 and a first pressing plate 6, the cylinder 2 is used to drive the first pressing plate 6 to press the tea brick from top to bottom, the second pressing device comprising a telescopic member 3 and a second pressing plate 7, the bottom end of the telescopic column of the telescopic member 3 is connected to the second pressing plate 7;

[0033] The linkage assembly includes a first fastener 4 fastened on the piston rod of the cylinder 2, a second fastener 5 fastened on the telescopic column of the telescopic member 3, a retractable positioning assembly arranged on the first fastener 4, a limiting assembly arranged on the second fastener 5 and a driving mechanism, the driving mechanism is used to drive the positioning assembly to be retracted and extended to engage or disconnect with the limiting assembly, and the cylinder 2 is also used to drive the telescopic column of the telescopic member 3 to rise and fall when the positioning assembly cooperates with the limiting assembly, thereby driving the second pressing plate 7 to rise and fall to press the tea brick.

[0034] Here, the meaning of "first fastener 4 and second fastener 5" refers to structures fixedly mounted on the piston rod of cylinder 2 and the telescopic column of telescopic member 3 respectively. In some embodiments, first fastener 4 and second fastener 5 are both connecting ring structures and can be connected and fastened by bolts.

[0035] Of course, the present application does not exclude the possibility of realizing the linkage of more than two rows of pressing devices through linkage components.

[0036] The utility model can realize linkage of arranged pressing devices through linkage components. Only the upgraded pressing mechanism of one pressing device is required as the active upgrading mechanism. The linkage components can drive the telescopic parts 3 of other pressing devices to rise and fall, so as to realize linkage and convenient disconnection of multiple rows of pressing devices, and can realize quick disconnection to facilitate replacement of tea brick molds and save energy. The linkage components can drive the clamping components to extend and retract through the driving mechanism to clamp or disconnect with the limiting components, so as to realize the clamping and matching of the clamping components and the limiting components conveniently and conveniently, and the operation is very efficient and convenient.

[0037] Preferably, please refer to Figure 3 As shown, the locking assembly includes a connecting bracket 15 and a locking member 19 which can be telescopically arranged relative to the connecting bracket 15, and the limiting assembly includes a limiting member 20, on which a limiting groove 21 is provided, and the driving mechanism is used to drive the locking member 19 to telescopically move in a direction close to or away from the limiting member so as to engage or disconnect the connection relative to the limiting groove 21.

[0038] It can be understood that the driving mechanism drives the locking member 19 to move to the limiting member 20 and cooperate with the limiting groove 21, so as to realize the locking connection between the two, realize the synchronous movement between the pressing devices, and facilitate the disconnection.

[0039] It should be noted that the driving mechanism can be a motor 10 or a mini cylinder. The motor 10 can be installed on the mounting frame 1 through a motor bracket. The mounting frame 1 also provides vertical installation for the cylinder 2 and the telescopic member 3. Specifically, the mounting frame 1 includes a supporting vertical plate 8 and a supporting horizontal plate 9. The supporting vertical plate 8 is symmetrically arranged along the center line of the supporting horizontal plate 9. The supporting vertical plate 8 is used to support the supporting horizontal plate 9. The cylinder 2 and the telescopic member 3 are installed through the supporting horizontal plate 9 respectively.

[0040] Preferably, the locking member 19 is connected to the driving mechanism via a multi-row connecting rod assembly, and the multi-row connecting rod assembly includes at least two connecting rods.

[0041] It is understandable that the multi-row connecting rod assembly has a stronger bending strength, which can improve the connection strength of the locking member 19 and ensure the overall strength and stability of the linkage assembly when in the connected state.

[0042] Preferably, please refer to Figure 3 and Figure 5 As shown, the multi-row connecting rod assembly includes a telescopic rod 18, a push rod 17 and a guide member 16. The first end of the telescopic rod 18 is connected to the locking member 19. The telescopic rod 18 and the push rod 17 are arranged in parallel and both pass through the guide member 16. The guide member 16 is fixedly connected to the first fastener 4 through the connecting bracket 15. The first end of the push rod 17 is fixedly connected to the telescopic rod 18 through the connecting plate. The driving mechanism is used to drive the push rod 17 to reciprocate along the axial direction of the push rod 17, and then drive the telescopic rod 18 to move synchronously through the push rod 17.

[0043] It can be understood that the push rod 17 drives the telescopic rod 18 to move back and forth while performing reciprocating motion, thereby driving the locking member 19 to move. The push rod 17 and the telescopic rod 18 are connected as a whole and move synchronously, which can improve the connection strength of the moving parts, that is, the push rod 17 enhances the bending resistance of the telescopic rod 18 and ensures the stability of the connection state of the linkage assembly.

[0044] Preferably, please refer to Figure 1 , 2 As shown in Figures 3, 5 and 6, the locking assembly also includes a rotating member 11, a first end of which is connected to the first fastener 4 via a bearing, a driving mechanism is used to drive the rotating member 11 to rotate, a displacement guide groove 12 is provided on the rotating member 11, a first guide column 27 is provided at the second end of the push rod 17, the first guide column 27 cooperates with the displacement guide groove 12, and the rotating member 11 is used to push the push rod 17 to reciprocate along the axial direction of the rotating member 11 through the displacement guide groove 12 when rotating, and then drive the telescopic rod 18 to move synchronously through the push rod 17.

[0045] It can be understood that the push rod 17 and the telescopic rod 18 are arranged in parallel, and both are arranged along the axial direction of the rotating member 11. When the rotating member 11 rotates, the push rod 17 can be pushed to reciprocate along the axial direction of the rotating member 11 through the displacement guide groove 12, and then the telescopic rod 18 can be driven to move synchronously through the push rod 17. Therefore, it is only necessary to control the rotational movement of the rotating member 11 to achieve the horizontal displacement of the push rod 17 and the telescopic rod 18. The setting of the rotating member 11 is conducive to compressing the space occupied by the linkage assembly in the horizontal direction, and realizing the arrangement of more rows of pressing devices in the workshop.

[0046] Preferably, please refer to Figure 1 , 2 As shown in Figures 3, 5 and 6, the rotating member 11 is a cylindrical structure, the displacement guide groove 12 is arranged along the cylindrical outer wall of the rotating member 11, and the displacement guide groove 12 includes a front end groove 1201, a connecting groove 1202 and a rear end groove 1203, the front end groove 1201 is formed on the outer wall of the second end of the rotating member 11, the front end groove 1201 is an arc groove structure parallel to the end face of the second end of the rotating member 11, the rear end groove 1203 is formed on the outer wall of the first end of the rotating member 11, the rear end groove 1203 is an arc groove structure parallel to the end face of the second end of the rotating member 11, and the connecting groove 1202 is provided with two and is used to connect the front end groove 1201 and the rear end groove 1203 to form a closed loop of the displacement guide groove 12.

[0047] It can be understood that the displacement guide groove 12 is a closed-loop structure, and the first guide column 27 performs a circular motion along the displacement guide groove 12. Since the front end slot 1201 is located at the second end of the rotating member 11, and the rear end slot 1203 is located at the first end of the rotating member 11, the two have a certain distance along the axial direction of the rotating member 11. As the rotating member 11 continuously rotates, when the first guide column 27 enters the front end slot 1201 from the rear end slot 1203 along the connecting slot 1202, the first guide column 27 is also pushed toward the second end of the rotating member 11, that is, the push rod 17 is simultaneously driven to move horizontally. The push rod 17 is restricted by the guide member 16 to only move horizontally, and then the push rod 17 drives the telescopic rod 18 to move synchronously. In this way, the rotational motion of the rotating member 11 is transmitted to the horizontal motion of the push rod 17 and the telescopic rod 18, which is conducive to shortening the overall horizontal space occupation of the linkage assembly through the setting of the rotating member 11.

[0048] Preferably, please refer to Figure 1-6 As shown, a turntable 13 is provided at the second end of the rotating member 11, and a direction-changing guide groove 14 is provided on the front end surface of the turntable 13. The second end of the telescopic rod 18 is slidably inserted into the sleeve 31. The telescopic rod 18 and the sleeve 31 are axially guided by the cooperation of convex strips and grooves. A second guide column 28 is provided at the rear end of the sleeve 31. The second guide column 28 cooperates with the direction-changing guide groove 14. A buffer spring is provided between the telescopic rod 18 and the positioning member 19. The direction-changing guide groove 14 is used to push the sleeve 31 and the telescopic rod 18 to rotate at an interval when the turntable 13 rotates with the guide member 16.

[0049] It should be noted that when the tea brick pressing process is carried out in stages and the lifting frequency of each stage is different, or when the lifting frequency of the second pressing device needs to be changed, the interval rotation of the telescopic rod 18 can drive the locking member 19 to rotate at intervals. When the locking member 19 adopts a plate structure and the limiting groove 21 adopts a strip groove structure, the turntable 13 rotates one circle to drive the locking member 19 to rotate twice. When the locking member 19 rotates to a state perpendicular to the limiting groove 21 of the strip groove structure, the locking member 19 does not cooperate with the limiting groove 21, that is, no locking action occurs, and the locking action is completed only when the locking member 19 rotates to the next position, so that the telescopic member 3 is linked with the cylinder 2 at intervals, and the lifting frequency of the telescopic member 3 is reduced. The telescopic member 3 is lifted passively, and there is no need for manual and frequent adjustment of the working speed of the motor 10 of the driving mechanism.

[0050] It should be noted that the sleeve 31 can rotate in the preset limiting hole of the guide member 16, the telescopic rod 18 can slide axially in the sleeve 31, and the rotation direction between the telescopic rod 18 and the sleeve 31 is limited. Specifically, a convex strip is provided on the outer wall of the telescopic rod 18, and a long groove is provided on the inner wall of the sleeve 31, and the convex strip and the groove cooperate to realize the axial guidance of the telescopic rod 18 in the sleeve 31.

[0051] Preferably, please refer to Figure 4 As shown, the redirecting guide groove 14 includes a first arc groove 1401, an intermediate connecting groove 1402 and a second arc groove 1403. The first arc groove 1401 and the second arc groove 1403 have different radii and are arranged on opposite sides of the turntable 13. The first arc groove 1401 and the second arc groove 1403 are both coaxially arranged relative to the axis of the rotating member 11. The intermediate connecting groove 1402 is set as a straight line structure and is provided with two, one of which connects the first end of the first arc groove 1401 with the first end of the second arc groove 1403, and the other intermediate connecting groove 1402 connects the second end of the first arc groove 1401 with the second end of the second arc groove 1403, so that the redirecting guide groove 14 forms a closed loop.

[0052] It is understandable that the telescopic rod 18 can only be displaced in the horizontal direction by being guided by the guide member 16. The telescopic rod 18 is provided with a sleeve 31 on its outer shell, and the sleeve 31 is inserted into the guide member 16. The sleeve 31 is provided with a second guide column 28, and specifically, the second guide column 28 is connected to the sleeve 31 through a connecting rod, and the connecting rod is vertically connected to the sleeve 31, so that the second guide column 28 and the sleeve 31 are kept parallel. When the turntable 13 rotates, the second guide column 28 slides in the direction-changing guide groove 14, and the second guide column 28 changes direction once when sliding from the first arc groove 1401 to the middle connecting groove 1402, and changes direction again when the second guide column 28 slides from the middle connecting groove 1402 to the second arc groove 1403, and the reciprocating motion drives the sleeve 31 and the telescopic rod 18 to rotate repeatedly.

[0053] Preferably, please refer to Figure 6 As shown, a connecting rod is provided at the rear end of the sleeve 31, and the connecting rod is arranged perpendicular to the axial direction of the sleeve 31. The first end of the connecting rod is connected to the sleeve 31, and the second end of the connecting rod is connected to the second guide column 28. The second guide column 28 and the connecting rod are perpendicular to each other.

[0054] It can be understood that the sleeve 31 is connected to the second guide column 28 through a connecting rod, and the connecting rod is in a vertical state with the sleeve 31 and the second guide column 28 at the same time, so as to realize the parallelism of the sleeve 31 and the second guide column 28, and then realize the rotation movement of the sleeve 31 driven by the second guide column 28 under the push of the change-of-direction guide groove 14.

[0055] According to another aspect of the utility model, a tea production device is also provided, which includes the above-mentioned multi-row linkage pressing mechanism.

[0056] The tea production device of the utility model also has the above-mentioned beneficial effects, including being able to realize linkage and convenient disconnection of multiple rows of pressing devices, being able to drive the lifting mechanisms of multiple devices to rise and fall synchronously through the lifting mechanism of one pressing device, and being able to realize quick disconnection to facilitate replacement of tea brick molds.

The above examples are only used to help understand the method and core ideas of the utility model. The above is only the preferred implementation method of the utility model.
