Description

Technical Field

[0001] The utility model relates to the technical field of granulators, in particular to an automatic feeding structure of a granulator. Background Art

[0002] The granulator introduces the high-viscosity molten material with a certain pressure into the rotating rollers through the feeding mechanism, and the outer periphery of the rotating rollers has many radial flow channel outlet holes. After the high-viscosity molten material contacts these flow channel outlet holes, it will be squeezed and dripped into granules. However, the existing feeding mechanism will naturally drop the raw materials after the raw materials are put in, and the raw materials are in powder form. The raw materials are easy to pile up with each other, resulting in a low density between the raw materials. When the raw materials enter the bottom and are squeezed by the rotating rollers, the raw materials cannot be extruded and formed, affecting the granulation quality. For this reason, we propose an automatic feeding structure for the granulator. Utility Model Content

[0010] Beneficial Effects

[0011] The utility model provides an automatic feeding structure for a granulator, which has the following beneficial effects:

[0012] 1. This kind of automatic feeding structure of the granulator, the granulator introduces the high-viscosity molten material with a certain pressure into the rotating rollers through the feeding mechanism, and the outer periphery of the rotating rollers has many radial flow channel outlet holes, and the high-viscosity molten material will be squeezed and dripped into granules after contacting these flow channel outlet holes. However, the existing feeding mechanism will naturally drop the raw materials after the raw materials are put in, and the raw materials are in powder form, and the raw materials are easy to pile up with each other, resulting in a low density between the raw materials. When the raw materials enter the bottom and are squeezed by the rotating rollers, the raw materials cannot be extruded and formed, affecting the granulation quality. In this article, when the equipment is in use, the raw materials can enter the shell through the feeding trough and contact with the two sets of forming rollers for extrusion and forming. At this time, the cylinder can be started to drive the driving rod to move up and down, and the driving rod can drive the pressing seat inside the feeding trough to squeeze the raw materials that are moving down, so that the raw materials entering between the two sets of forming rollers are repeatedly pressed down and compacted, increasing the compactness of the raw materials themselves, thereby achieving the effect of improving the granulation quality of the raw materials.

[0013] 2. This kind of granulator has an automatic feeding structure, and a feeding cover is rotatably provided on the upper outer part of the driving rod. The outer periphery of the feeding cover cooperates with the inner limit of the limit slide through a limit assembly. When the cylinder is started and the driving rod is driven up and down, the feeding cover outside the driving rod can simultaneously drive the raw materials inside the feeding trough up and down, so that the incoming raw materials can be pressed downward to guide the material to avoid accumulation, thereby achieving the effect of improving the feeding efficiency.
