Anti-slip mechanism of ring die granulator

Abstract

The invention discloses an anti-slip mechanism of a ring die granulator. The anti-slip mechanism comprises a main shaft, a transmission wheel, a hoop, a ring die, compression rollers, a gear ring and a pressing plate, the transmission wheel is connected to the main shaft through a bearing, the front portion of the transmission wheel is connected with the ring die through the hoop, the ring die is connected with the gear ring, the two compression rollers are arranged at the front end of the main shaft in parallel, and pinions are arranged at the front ends of the compression rollers. The pinions are meshed with the gear ring, the rear ends of the compression roller shafts of the compression rollers are inserted into the installation hole of the main shaft, the front ends of the compression roller shafts of the compression rollers are connected with the reserved hole in the pressing plate, and the pressing plate is connected with the main shaft. The ring die and the compression rollers form a transmission pair, and the compression rollers are forcibly driven to rotate while the ring die rotates instead of being driven to rotate by virtue of friction force of a material layer between the ring die and the compression rollers so that the situation that materials cannot enter theintake area of the compression rollers and cannot be granulated due to the fact that the compression rollers slip due to insufficient friction force is prevented.

Description

technical field [0001] The invention belongs to the technical field of granulation, and relates to an anti-slip mechanism of a ring die granulator, in particular to the processing and manufacture of a ring die granulator which can prevent slippage of the ring die and pressure rollers in the production process, and is the core of pellet feed production Processing Equipment. Background technique [0002] In recent years, with the continuous improvement of the living standards of Chinese residents and the promotion of consumption upgrades, the demand for high-end livestock and poultry products with high nutritional value and special aquatic products has gradually increased. According to the statistics of the National Feed Industry Association, my country is not only the world's largest It is the world's largest consumer of livestock and poultry products and aquatic products, and its feed output has also ranked first in the world for many years. [0003] However, in the process ...

Problems solved by technology

[0004] At present, steam heating is generally used for aging before granulation in my country. Due to the need for high-temperature granulation, the amount of steam added increases significantly, and the moisture content of raw materials before entering the granulator also increases; The ring die rotates and then relies on the friction with the material to drive the pressure roller to rotate, and then the material is taken into the pressing area between the ring die and the pressure roller to complete the granulation process. The pressure roller itself has no independent power, and its movement is completely dependent on the material. The friction between them is driven by the ring die to rotate. When the amount of steam added to the material increases, the moisture content will inevitably increase. When the moisture content of the material increases to a certain level, the friction coefficient between the material, the pressure roller and the ring die will decrease sharply. , so that the pressure roller cannot rotate through the friction with the material, which is commonly known as pressure roller slippage. If the pressure roller does not rotate, the material cannot be ingested by the pressure roller into the pressing area, which greatly reduces the production capacity of the granulator. In severe cases, it may even cause completely unable to granulate
