[0002] In the cement industry, the main function of the cover body of the powder inlet of the tableting machine is sealing and purging. In the prior art, the opening and closing of the cover body is mainly achieved by the up and down movement of the cover body and the rotation movement around the side fulcrum. For example, the patent application with patent application number CN202110163802.4 discloses "a sample making device for material detection and analysis". In this scheme, the cover body is lifted up and down by a cover pressing cylinder, and the cover body is rotated by a rotating component. The two components realize the lifting and rotation of the cover body, which requires high assembly precision and has a complex structure, resulting in high cost. When the cover body is closed, a large radial force will be applied to the cylinder shaft when the cover body is pressed into the hopper. The uneven force affects the service life of the cylinder, and the existing cover body still has the problem of poor sealing after closing. How to simplify the opening structure, extend the service life of the drive mechanism, and solve the problem of poor sealing after closing are technical problems that need to be urgently solved by technical personnel in this field.

[0023] The feeding and opening device for the automatic grinding and pressing machine of the present embodiment can realize the lifting and rotation of the cover body 4 through a lifting and rotating driving mechanism 1, and the overall structure is simpler and the cost is lower; when the cover needs to be closed, the lifting and rotating driving mechanism 1 drives the flat rotating flange 2 to rotate, drives the cover bracket 3 and the cover body 4 to rotate, so that the cover body 4 moves to the top of the feeding port, and then the lifting and rotating driving mechanism 1 drives the flat rotating flange 2 to move downward, thereby driving the cover bracket 3 and the cover body 4 to descend. When the cover body 4 contacts the top surface of the feeding hopper, the cover body 4 will be subjected to resistance and gradually stop descending. At this time, the flat rotating flange 2 will continue to descend with the lifting and rotating driving mechanism 1, so that the end of the cover bracket 3 connected to the flat rotating flange 2 gradually tilts downward and presses the elastic component 7 on the flat rotating flange 2. At this time, the cover bracket 3 is subjected to a reverse force, which provides a bending moment pressure on the cover body 4, so that the cover body 4 is pressed against the top surface of the feeding hopper, thereby obtaining a better sealing effect.

[0024] In this embodiment, the cover support 3 includes a first connecting arm 31 for connecting with the plane rotating flange 2 and a second connecting arm 32 for connecting with the cover body 4. The first connecting arm 31 is two straight arm structures arranged opposite to each other, and the two straight arm structures are installed on the plane rotating flange 2 through the first connecting shaft 5; the second connecting arm 32 includes two arc-shaped arm structures arranged opposite to each other, and the two arc-shaped arm structures are connected to the cover body 4 through the second connecting shaft 6. The connection between the cover body 4 and the plane rotating flange 2 is realized by the first connecting arm 31 and the second connecting arm 32, and the cover body 4 can swing around the second connecting shaft 6, so that the cover can be evenly stressed after closing.

[0025] In this embodiment, the lifting and rotating driving mechanism 1 is a planar rotary clamping cylinder, and the rotation and lifting of the cover body 4 can be achieved through one mechanism. The overall structure is simpler, the assembly is more convenient, and the cost is lower.

[0026] In this embodiment, the elastic component 7 is a spring ball head screw; when the spring ball head screw contacts the cover bracket 3, it provides a certain elastic tightening force to keep the cover bracket 3 horizontal. In other embodiments, the elastic component 7 includes a spring and a ball structure, one end of the spring is installed in the slot of the flat swivel flange 2, and the ball structure is installed at the other end of the spring.

[0027] In this embodiment, a sealing member 8 (such as a sealing ring) is provided on the contact surface between the cover body 4 and the feed hopper, and a good seal can be achieved between the cover body 4 and the top surface of the feed hopper through the sealing member 8 .

[0028] like Figure 2 As shown, in this embodiment, a guide plate 9 is provided inside the cover body 4, and there is a gap between the top of the guide plate 9 and the inner wall of the cover body 4. A vent hole is opened on the cover body 4, and the gas enters the gap between the top of the guide plate 9 and the inner wall of the cover body 4 through the vent hole.
