The two No. 1 punching rods 18 are symmetrically arranged along the center line of the mounting sleeve 17, and the two No. 2 punching rods 19 are symmetrically arranged along the center line of the mounting sleeve 17, and the mounting sleeve 17 is provided with a fastening hole 20 with an internal thread, and a fastening bolt for fixing the mounting sleeve 17 is screwed into the fastening hole 20. The rotating rod driving assembly can drive the rotating rod 16 to rotate. The rotation of the rotating rod can drive the mounting sleeve 17 installed with the No. 1 punching rod 18 and the No. 2 punching rod 19 to rotate for stirring, thereby preventing the powder from being blocked at the connection between the conical feed port and the spinning channel.

[0035] Specifically, the spinning feeding mechanism 5 includes a spiral feeding rod 25 horizontally arranged in the spinning channel 4, one end of the spiral feeding rod 25 is connected to a rotary driver through a screw gear 26, and the other end of the spiral feeding rod 25 extends into the feed port 10 of the forming block 9. When the spiral feeding rod rotates, the powder can be fed into the forming cavity of the forming block through the feed 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.

[0036] Those skilled in the art should understand that the rotary driver may be a rotary cylinder or a motor, etc. The rotary driver is not shown in the figure.

[0037] Specifically, the material blocking assembly 13 includes a material blocking seat 27 arranged on the front side of the forming block 9, a material blocking block 28 driven by a lifting assembly is arranged in the middle of the material blocking seat 27, two unloading plate connecting plates 29 are fixedly connected to the bottom sides of the material blocking block 28, a unloading plate 30 is arranged between the two unloading plate connecting plates 29, and the inner ends of the unloading plates 30 are rotatably connected to the lower sides of the unloading plate connecting plates 29 through rotating shafts, and a support rod 31 located on the lower side of the unloading plate 30 is arranged on the front side of the material blocking block 28; the lifting assembly includes a lifting driver 32 fixed to the top of the material blocking seat 27, and the output shaft end of the lifting driver 32 is connected to the material blocking block 28.

[0038] The lifting drive can drive the stop block to rise and fall in the vertical direction so that the stop block can be moved to the front side of the discharge port for blocking. When a conventional unloading plate is used for unloading, there will be a gap directly below the unloading plate to avoid interference between the stop block and the unloading plate. When the flip unloading plate structure in the present application is used, there is no gap directly below the unloading plate during unloading, and the stop block will not interfere with the unloading plate when it moves; specifically, when the stop block moves downward, the stop block can drive the unloading plate connecting plate to move downward, and the downward movement of the unloading plate connecting plate can drive the outer end of the unloading plate to flip upward, and the inner end of the unloading plate moves downward with the unloading plate connecting plate; the support rod can support the outer end of the unloading plate so that the unloading plate is in a certain inclined state during unloading, and when the stop plate moves downward, the unloading plate can also flip with the support rod as the fulcrum.

When too much powder is added to the hopper and causes the powder to be blocked at the bottom of the conical feed port, the pressing assembly can press the powder down to the spinning feeding mechanism to prevent the powder from being unable to be transmitted due to blockage.

[0043] Specifically, the pressing drive assembly includes a pressing drive 37 fixed obliquely on the outside of the hopper 3, the output shaft of the pressing drive 37 is inserted into the inside of the hopper 3 and connected to the pressing plate 36, and the pressing drive 37 is parallel to the side wall of the pressing side 35 of the hopper 3.
