Description
Technical Field
[0001] The present application relates to the technical field of extrusion granulators, and in particular to a high-efficiency granulator. Background Art
[0002] Granulator is a kind of molding machine which can make materials into specific shapes. The spheronization granulation method is to first extrude the wet mass drug into strips through a sieve plate, cut it into rod-shaped small particles, and then roll it into round particles in a centrifugal disk.
[0003] The existing granulator includes an extruder, a cooling device, a drying device, a cutting device, a collecting device and a packaging device. A die head and a barrel are arranged at the transmission end of the extruder. One end of the barrel is fixedly connected to the extruder, and the other end of the barrel is fixedly connected to the die head. A discharge hole is opened on the end face of the die head. The extruded processed material is extruded into strip-shaped processed material for cutting by the cutting device according to the shape of the discharge hole. After passing through the cooling device, the drying device and the cutting device, the strip-shaped processed raw material is cut into granules. After being collected and packaged, it can be put into the next stage of production.
[0004] The requirements for particle diameter are different during the production process. One die head can only generate one particle diameter. If the required particle diameter changes, the production diameter can only be changed by replacing the die head. However, the disassembly and assembly of the die head is cumbersome and time-consuming, which leads to reduced production efficiency. Utility Model Content

[0019] Optionally, a limiting ring is fixed to the outer side wall of the discharge die head, and a limiting rod is rotatably connected to the side wall of the machine body, and the limiting rod is in an "L" shape.
[0020] By adopting the above technical solution, the limiting rod is "L"-shaped, and the limiting rod contacts the end face of the limiting ring to limit the position of the limiting ring, thereby limiting the position of the discharge die head and enhancing the stability of the discharge die head.
[0021] Optionally, the inner side wall of the limiting rod is provided with a rolling ball for reducing friction between the limiting ring and the limiting rod.
[0022] By adopting the above technical solution, the rolling ball reduces the friction between the limiting ring and the limiting rod, making it easier for the discharge die head to rotate.
