The upper hydraulic cylinder is fixed to the upper part of the support frame, and its piston rod has a mold pressing block. The lower hydraulic cylinder corresponds to the upper hydraulic cylinder and is located at the lower part of the support frame. The clamping and positioning mechanism is located on both sides of the lower hydraulic cylinder and includes two clamping plates. The lower parts of the two clamping plates are connected to meshing gears. One clamping plate is connected to the piston rod of the cylinder.

[0016] This utility model has the following beneficial effects:

[0017] This utility model provides a high-efficiency biomass briquette solid fuel forming machine. A fixed frame is used to mount a first cylinder, which moves the frame. A stirring rack stirs the fuel powder. A second cylinder drives the upper mold pressing frame, indirectly compressing the fuel. A solid fuel forming mold stores and shapes the fuel.

Then, the second cylinder is opened, which drives the upper mold pressure frame to move downward, thereby shaping the raw material. Finally, the third cylinder is opened, which drives the ejector block frame to move upward, ejecting the solid raw material. Under the action of the mounting frame, the material is moved to the inner cavity of the storage box. During the transfer, the second motor is activated, which drives the second auger to rotate and discharge the material through the discharge chute. This system has the advantages of high working efficiency and automatic filling, solving the problem that existing molding machines rely on manual filling, which is not only time-consuming but also reduces the working efficiency of the molding machine.
