DETAILED DESCRIPTION

[0025] like Figure 1-Figure 4 As shown, a forming mechanism of a powder spin-forming briquetting machine comprises a machine body 1, wherein a hopper 2 is arranged in the machine body 1, a spin-forming feeding mechanism is arranged at the bottom of the hopper 2, a briquetting component 3 connected with the discharge port of the spin-forming feeding mechanism is also arranged in the machine body 1, the briquetting component 3 comprises a forming block 5 with a forming cavity 4, the forming block 5 is provided with an inlet 6, a push port 7 and a discharge port 8 connected with the forming cavity 4, the push port 7 and the discharge port 8 are arranged opposite to each other, a blocking component 9 and a push port 10 corresponding to the discharge port 8 and the push port 7 are respectively arranged on the front and rear sides of the forming block 5, and the feeding direction of the spin-forming feeding mechanism is perpendicular to the pushing direction of the push port 10.

[0026] In the utility model, the powder is fed into the forming cavity 4 of the forming block 5 by the spinning feeding mechanism, and the pressure of the spinning feeding mechanism itself can be used to squeeze the powder into blocks, and the blocking component 9 and the pushing component 10 can be used for secondary extrusion to improve the compactness of the powder block, and there is no need to set up an independent powder briquetting device, which can reduce the volume of the equipment and reduce the cost of the equipment;

[0027] Specifically, the spinning feeding mechanism can feed the powder into the molding cavity through the feed port 6. When the powder is extruded into blocks, the blocking assembly 9 and the pushing assembly 10 can respectively block the pushing port 7 and the discharge port 8 of the molding block 5 so that the molding cavity can be in a closed state to facilitate the extrusion of the powder into blocks. When the discharge port is in a closed state, the pushing assembly can also perform secondary extrusion on the powder blocks that have completed the initial extrusion in the molding cavity. After the powder is extruded into blocks, the blocking assembly 9 is removed, and the powder blocks in the molding cavity can be pushed out from the discharge port through the pushing assembly 10.

[0028] Specifically, the material blocking assembly 9 includes a material blocking seat 11 arranged on the front side of the forming block 5, and a material blocking block 12 driven by a lifting assembly is arranged in the middle of the material blocking seat 11. The lifting assembly can drive the material blocking block to rise and fall in the vertical direction so as to move the material blocking block to the front side of the discharge port for blocking.

[0029] Preferably, the bottom of the stopper block 12 is also connected with a flip unloading plate structure, which includes two unloading plate connecting plates 13 symmetrically arranged on both sides of the bottom of the stopper block 12, and a unloading plate 14 is arranged between the two unloading plate connecting plates 13, and the two sides of the inner ends of the unloading plate 14 are rotatably connected to the lower side of the unloading plate connecting plate 13 through a rotating shaft. When a conventional unloading plate is used for unloading, there will be a gap between the unloading plate and the stopper block 12 to avoid interference between the unloading plate and the unloading plate. When the flip unloading plate structure in the present application is used, there is no gap between the unloading plate and the stopper block 12 during unloading, and the unloading block will not interfere with the unloading plate when moving; specifically, when the stopper block 12 moves downward, the stopper block 12 can drive the unloading plate connecting plate 13 to move downward, and the unloading plate connecting plate 13 can drive the outer end of the unloading plate 14 to flip upward, and the inner end of the unloading plate moves downward with the unloading plate connecting plate 13.

[0030] Specifically, a support rod 15 located on the lower side of the unloading plate 14 is provided on the front side of the blocking block 12. The support rod can support the outer end of the unloading plate so that the unloading plate is in a certain tilted state during unloading, and when the blocking plate moves downward, the unloading plate can be flipped with the support rod as the fulcrum.

[0031] Specifically, the lifting assembly includes a lifting driver 16 fixed to the top of the material blocking seat 11, and the output shaft end of the lifting driver 16 is connected to the material blocking block 12. The lifting driver can drive the material blocking plate to rise and fall in the vertical direction.

[0032] Those skilled in the art should understand that the lifting drive may be an oil cylinder, an air cylinder or a linear motor, etc.

[0033] Specifically, the pusher assembly 10 includes two pusher driver mounting plates 17 fixed on the side wall of the molding block 5 near the pusher port 7, and the two pusher driver mounting plates 17 are fixedly connected with a pusher driver 18 at one end away from the molding block 5, and the output shaft end of the pusher driver 18 is fixedly connected with a pusher plate 19 that can be inserted into the pusher port 7. The pusher driver 18 can drive the pusher plate 19 to enter from the pusher port in the horizontal direction and push the material in the molding cavity from the discharge port to the discharge plate.

[0034] Those skilled in the art should understand that the push drive may be an oil cylinder, an air cylinder or a linear motor, etc.

[0035] Specifically, the cross sections of the feed inlet 6, the pusher port 7 and the discharge port 8 are all circular.

[0036] Preferably, two wear-resistant blocks 20 are also provided on the material stopper seat 11, and the wear-resistant blocks 20 abut against the front side wall of the material stopper block 12. The wear-resistant blocks 20 can limit the front side of the material stopper block, and the use of wear-resistant blocks can reduce wear and increase the service life of the equipment.

[0037] Specifically, the spinning feeding mechanism includes a horizontally arranged spiral feeding rod 21. When the spiral feeding rod 21 rotates, the powder can be fed into the forming cavity 4 of the forming block 5 through the feeding port, and when the spiral feeding rod continues to rotate, the powder can be continuously fed into the forming cavity, so that the powder can be squeezed into a block by the pressure generated by the continuous feeding.
