The utility model content

The purpose of the utility model provides a kind of ring die pelleter, makes that the granulator structure is compact more, efficient is higher, noise is low, long service life.

The purpose of the utility model is achieved in that a kind of ring die pelleter, comprises the reduction box that is installed on the support, and the middle part of said reduction box is run through and is provided with rotor; The axle front and back end of said rotor all is installed on the reduction box through bearing, and the front end face of rotor is equipped with the ring mould, and rotor is fixedly connected through anchor ear with encircling between the mould; The front end face of said ring mould is equipped with the feeding awl; Said internal rotor axle center is provided with main shaft disk, is rotatably installed with pressure roller respectively in two horizontal symmetrical axis holes of main shaft disk front end, and the periphery fixed cover of said rotor is equipped with driven gear wheel; The front end face of said reduction box is equipped with a body through hinge; The front end face of door body is installed with feed hopper, and the below bilateral symmetry of said driven gear wheel is engaged with two driver pinions, and two said driver pinions are installed in rotation on the reduction box through bearing; Said two driver pinions are in transmission connection through the output shaft of shaft coupling and two drive motors respectively, and said two drive motors are installed on the support.

During the utility model work; Start two drive motors, two drive motors are given two shaft couplings with transmission of power respectively, and two shaft couplings are given two drive pinion shafts transmission of power respectively again; Two drive pinion shafts are done to slow down with driven gear wheel generation gear motion and driven in common rotor respectively again and are rotatablely moved; And rotor drives the ring mould and rotates, and this moment, material joined feed hopper from quality-adjusting device, and the chute in the feed hopper is input to feeding awl with material again; The feeding awl of rotation gets rid of material through action of centrifugal force just granulates indoor into the granulator working space; Material formed frictional force and drove the pressure roller rotation between ring mould and pressure roller this moment, and the ring mould of rotation and pressure roller are pressed into material in the nib of ring mould continuously, and material is extruded through high pressure, high speed in ring mould nib; Be cut into the discharging opening that graininess flows out the door body through cutting knife again, accomplish pelletization.

Compared with prior art, beneficial effect of the present invention is: this device is through adopting two the driving, and the required general power P of rotor is shared by two driver pinions jointly; The power of each pinion burden is P/2; It is littler to make that the design modulus of pinion can be selected for use, and it is more that the number of teeth can be selected for use, can significantly improve gear pair registration and mesh stiffness; Thereby the pinion operation is more steadily reliable, longer service life; Simultaneously, through adopting two the driving, gear wheel and rotor are stressed balanced more; Dynamic characteristic is good, and two driver pinion symmetries have been offset the most bending force of rotor, can improve the stability of pelletization and the life-span of transmission component effectively; When granulator will take place to block up machine, two drivings can provide the locked-rotor torque of two motors, helped improving the anti-stifled capabilities of granulator; And when starting, can successively start two drive motors respectively, to reduce impact to electrical network.The present invention can be used in the high-power ring die pelleter.

For the ease of quality-adjusting device and suspension ring are installed, the top of said reduction box is symmetrically arranged with two triangle platforms, and each platform upper surface all offers three quality-adjusting device installing holes, and each platform side surface all offers two suspension ring screws.
