Fig. 1 is a schematic structural view of a pressure maintaining mechanism according to an embodiment of the present utility model, and fig. 2 is a schematic structural view of another view of the pressure maintaining mechanism according to an embodiment of the present utility model, as shown in fig. 1 and fig. 2, the pressure maintaining mechanism includes a mounting frame 1, and a lifting assembly 2 and a pressing assembly 3 disposed on the mounting frame 1. It should be noted that the structure of the mounting frame 1 may be set according to actual requirements such as cost, occupied space, and the like, which is not limited herein. Further, fig. 3 is a schematic structural diagram of a jacking assembly according to an embodiment of the present utility model, and as shown in fig. 3, the jacking assembly 2 includes a first driving member 21, a supporting member 22, a bearing member 23, and a connecting member 24. The support 22 is movably disposed on the mounting frame 1 along a vertical direction, and a guide groove 221 is disposed on the support 22 along an inclined upward direction, and the guide groove 221 is in a structure of an inclined elongated slot. In addition, the top of the supporting piece 22 is provided with a bearing piece 23, and the bearing piece 23 is used for bearing a carrier A with products, so that the jacking component 2 jacks up the carrier A, and the products on the carrier A are pressurized by matching with the pressing component 3. Further, fig. 4 is a schematic cross-sectional view of a jacking assembly according to an embodiment of the present utility model, as shown in fig. 4, the connecting member 24 includes a rotating portion 241, and a connecting portion 242 and a guiding portion 243 formed by extending the rotating portion 241 in different directions, and the rotating portion 241, the connecting portion 242 and the guiding portion 243 are spaced apart from each other, so that the connecting member 24 is formed into a V-shaped structure. The rotating portion 241 is rotatably connected to the mounting frame 1, the connecting portion 242 is connected to the first driving member 21, and the guiding portion 243 is slidably disposed in the guiding groove 221. Therefore, the first driving member 21 can drive the connecting portion 242 to rotate the connecting member 24 through the rotating portion 241, so that the guiding portion 243 can slide in the guiding slot 221, and further the supporting member 22 moves up and down under the action of the guiding portion 243, so as to drive the carrier 23 to move up and down, i.e. drive the carrier a to move up and down.

In one embodiment, the first driver 21 is a cylinder. Specifically, as shown in fig. 4, a piston rod of the air cylinder is connected to a connecting portion 242 of the connecting member 24, and a cylinder tube of the air cylinder is rotatably provided on the mounting bracket 1. Thus, the cylinder can cooperate with the connector 24 to drive the support 22 up and down. It is easy to understand that when the air cylinder pushes the connecting portion 242, the guiding portion 243 moves obliquely upward along the guiding slot 221, and the supporting member 22 can move downward under the action of the guiding portion 243 to drive the carrier a on the carrier 23 to move downward.

On the other hand, when the carrier 23 moves upward through the first driving member 21, the connecting member 24 and the supporting member 22 and lifts up the carrier a, the pressing assembly 3 moves toward the carrier 23 to press the product on the carrier a, thereby completing the pressure maintaining work on the product. It will be readily appreciated that when the product pressure maintaining is completed, the first driving member 21 drives the connecting member 24 to drop the carrier a on the carrier 23, and the pressing assembly 3 moves away from the carrier 23 to disengage the product on the carrier a. Therefore, the pressure maintaining mechanism can be used for maintaining the pressure of the product on the carrier A by matching the jacking component 2 with the pressing component 3. In one embodiment, the dwell mechanism, by providing a sensor and controller, may enable automatic dwell upon detecting the presence of a carrier a between the jacking assembly 2 and the pressing assembly 3.

Specifically, the first and second buffers 25 and 26 are located below the connecting portion 242 and the guide portion 243, respectively. Thus, when the first driving member 21 pulls the connecting member 24, the connecting member 24 rotates toward the first buffer member 25 until the connecting portion 242 abuts against the first buffer member 25 to receive the buffer action of the first buffer member 25. Correspondingly, when the first driving member 21 pushes the connecting member 24, the connecting member 24 rotates toward the second buffer member 26 until the guiding portion 243 abuts against the second buffer member 26 to receive the buffer action of the second buffer member 26.

In one embodiment, as shown in fig. 3, a slide rail 222 is provided on the support 22. On the other hand, the jacking assembly 2 further comprises side plates 27, and the side plates 27 are located outside the support 22.

Further, a blocking cylinder 42 is provided between the two conveyor belts 41 and is configured to eject when the carrier a moves between the jacking assembly 2 and the pressing assembly 3, so as to realize that the carrier a is blocked from moving further, so that the jacking assembly 2 cooperates with the pressing assembly 3 to pressurize the product on the carrier a. It should be noted that the number and positions of the blocking cylinders 42 may be set as needed, for example, one blocking cylinder 42 may be added so as to block the carrier a containing the product to be pressurized outside when the pressurizing mechanism pressurizes one product.

In one embodiment, as shown in fig. 7, the transfer assembly 4 further includes two fasteners 43. Specifically, two fixing pieces 43 are located outside the two conveyor belts 41, respectively.

Further, the limiting member 44 is configured to abut against the carrier a from obliquely above when the carrier a moves between the jacking assembly 2 and the pressing assembly 3, so as to limit the carrier a from moving continuously, so that the jacking assembly 2 can cooperate with the pressing assembly 3 to maintain the pressure of the product on the carrier a. It will be readily appreciated that when the product dwell is completed, the stop 44 is disengaged from carrier a so that carrier a continues to be conveyed by conveyor 41.

The structure of the pressure maintaining mechanism is as described above, and will not be described herein. Further, the gripping mechanism 6 is configured to grip the carrier a to the first outfeed channel 5. Therefore, after the pressure of the product on the carrier A is maintained by the pressure maintaining mechanism, the carrier A filled with the qualified product can be clamped to the first discharging channel 5 by the clamping mechanism 6 for subsequent work.

As shown in fig. 9, in one embodiment, the automated pressure maintenance device further comprises a second discharge channel 7.
