Description

Technical Field

[0001] The invention belongs to the field of loading and unloading devices, and in particular relates to an integrated loading and unloading device for a ring die pressing roller of a granulator. Background Art

[0002] Ring die pelletizing machine is a mechanical equipment that utilizes solid materials for extrusion forming. Its working principle is to compress the raw materials into granular materials of the required size through the pressure inside the annular die (ring die) and the rotation of the external roller (pressure roller). During the working process, the ring die rotates clockwise, and the tempered raw materials enter the granulation chamber. After the raw materials enter the working area, the pressure roller will also rotate clockwise driven by friction. The rotation of the die roller makes the raw materials move forward at high speed, and the extrusion pressure gradually increases. When the extrusion pressure increases to a certain extent, the raw materials will overcome the friction and enter the ring die hole. With the continuous rotation of the roller die, the raw materials continue to enter the ring die hole, and are squeezed out of the ring die hole after forming and cut off to form the required product.

[0003] At present, in the prior art, the ring die is usually loaded and unloaded by a wire rope lifting device. However, the ring die is easily shaken by hanging it in the air, which poses a safety hazard. In addition, the pelletizer roller cannot be loaded and unloaded. When encountering obstacles during movement, it is difficult to lift the device. Further improvement is needed.

[0004] Therefore, an integrated loading and unloading device for the ring die and roller of the pelletizer is proposed. The ring die is hoisted in the air for loading and unloading, which is prone to shaking and poses a safety hazard. The position of the roller can be quickly adjusted for loading and unloading, which is convenient for assembly and disassembly. The device can be lifted up when encountering obstacles during movement. Summary of the invention

Since the sprocket 8 and the chain 5 are engaged, the vertical plate 501 will be pulled upward, and the U-shaped loading and unloading block 506 will be pulled up, so that the position of the ring die can be lifted and flexibly adjusted, reducing labor intensity. The device is equipped with a first universal wheel 10 and a second universal wheel 12, which can be flexibly moved when loading and unloading the ring die and the pressure roller without manual handling.

By providing the second fixing plate 17 and the first adjusting block 18, the stability of the lifting cylinder 21 when moving in the vertical direction can be enhanced;
