Fig. 1 is a schematic structural diagram of a pressing device provided in an embodiment of the present application.

The structure and the working principle of the material pressing device are further explained by taking the pressing after the silicon carbide powder is filled into the crucible in the silicon carbide crystal growth process as an embodiment, and the crucible filled with the silicon carbide powder is shown by a dotted line in fig. 2. The above is only an exemplary embodiment, and the application place of the pressing device is not limited.

The pressing device shown in fig. 1-2 comprises a bracket 10, a turntable 20, a connecting rod 30, a transmission rod 40, a limiting cylinder 50 and a pressing part 60. The rotary table 20 is rotatably disposed on the support 10, a first operation portion 21 is disposed at a rotation center of one side surface of the rotary table 20, and the rotation of the rotary table 20 is realized by the first operation portion 21; the other side surface of the rotating disc 20 is provided with a protruding part 22 deviating from the rotating center, so that when the rotating disc 20 rotates, the protruding part 22 deviating from the rotating center can do circular motion; one end of the connecting rod 30 is hinged with the extension part 22; one end of the transmission rod 40 is hinged with the other end of the connecting rod 30; the limiting cylinder 50 is arranged on the bracket 10, and the transmission rod 40 can penetrate through the limiting cylinder 50; the swage portion 60 is connected to the other end of the transmission rod 40.

The movement of the turntable 20 and related structures is further described with reference to fig. 3-5.

Fig. 3 shows a state where the projecting portion 22 moves to the highest point. As shown in fig. 3, when the rotary plate 20 is rotated on the stand 10 about the rotation center by the first operating portion 21 in the direction indicated by the arrow in fig. 3, the protruding portion 22 disposed eccentrically from the rotation center makes a circular motion, and at the same time, one end of the link 30 hinged to the protruding portion 22 also makes a circular motion. The other end of the connecting rod 30 is hinged with a transmission rod 40, when the extending part 22 moves to the highest point, the connecting rod 30 and the transmission rod 40 are positioned on a straight line, and the material pressing part 60 is positioned at the highest point. As the turntable 20 continues to rotate in the direction indicated by the arrow in fig. 3, the transmission rod 40 starts to move the bottom swage portion 60 downward in the direction indicated by the arrow in fig. 3, so that the turntable 20 rotates from the position shown in fig. 3 to the position shown in fig. 4, which is the state shown in fig. 4 when the extension 22 moves between the highest point and the lowest point. As shown in fig. 4, the connecting rod 30 and the transmission rod 40 are not located on a straight line, the connecting rod 30 drives the transmission rod 40 to incline when in an inclined state, and due to the limiting effect of the limiting cylinder 50 arranged on the bracket 10 on the transmission rod 40, the transmission rod 40 can only move up and down in the vertical direction, and the end of the connecting rod 30 hinged to the transmission rod 40 is limited to move up and down. As the turntable 20 continues to rotate in the direction indicated by the arrow in fig. 4, the transmission rod 40 continues to drive the bottom swage portion 60 downward in the direction indicated by the arrow in fig. 4, so that the turntable 20 rotates from the position shown in fig. 4 to the position shown in fig. 5, which is the state shown in fig. 5 when the protrusion 22 moves to the lowest point. When the extension 22 moves to the lowest point, the connecting rod 30 and the transmission rod 40 are located on a straight line, and the pressing portion 60 is located at the lowest point and cannot move downward any more. When the turntable 20 continues to rotate in the direction indicated by the arrow in fig. 5, the transmission rod 40 will drive the bottom pressing portion 60 to move upward, and the pressing portion 60 rises from the lowest point to the highest point, and the process is repeated. The moving distance of the protruding portion 22 in height from the highest point to the lowest point is the moving distance of the swage portion 60.

When the turntable 10 rotates, one end of the connecting rod 30 hinged to the extension part 22 performs circular motion, and one end hinged to the transmission rod 40 performs vertical up-and-down motion, so as to drive the transmission rod 40 to perform vertical up-and-down motion, and further drive the material pressing part 60 connected to the transmission rod 40 to perform vertical up-and-down motion, thereby completing the action of compacting the powder material surface in the crucible. Because the movement of the material pressing part 60 is regular reciprocating up and down movement, the movement path is not changed, and the material pressing part 60 continuously moves from the position shown in fig. 3 to the position shown in fig. 5 when the rotating disc 20 rotates, the material pressing part 60 can be stressed more uniformly when acting on the material surface, thereby being beneficial to subsequent processing and manufacturing and simultaneously reducing the labor capacity of operators.

When the second operation portion 71 is rotated, the support portion 80 is rotated by the first gear 81 and the second gear 72 engaging with each other. When the diameter of the second gear 72 is smaller than the diameter of the first gear 81, the second gear 72 on the second operation portion 71 is a small gear, the first gear 81 on the support portion 80 is a large gear, and the small gear drives the large gear to rotate more easily.

In one embodiment, the second operating portion 71 is an operating handle, and a second gear 72 is fixed to one end of the operating handle, and the supporting portion 80 is driven to rotate by the engagement of the gears. In addition to the above-mentioned structure, other structural forms may be selected to complete the rotation of the supporting portion 80, for example, a motor-driven form may be adopted.
