Technical Field

[0001] The utility model relates to the technical field of ring die pelletizers, in particular to a rotor assembly of a ring die pelletizer. Background Art

[0002] Ring die pellet mill is a feed pelleting equipment, which is a feed processing machine that directly presses pellets from crushed materials such as corn, soybean meal, straw, grass, rice husk, etc. Ring die pellet mill is the main feed machinery and equipment for producing pellet feed. Its performance determines the feed processing output to a large extent, and it plays a very important role in the feed processing process.

[0003] For example, the Chinese patent with publication number CN214863360U proposes a rotor assembly for a ring die pelletizer. When lubrication is required at the bearing of the rotor assembly, the patent rotates the rotating handle to rotate the threaded fixing rod, and the rotation of the threaded fixing rod drives the pressure plate to move downward. The lubricating fluid inside the oil storage box is transported to the inside of the bearing for lubrication under the action of extrusion, and the descent of the pressure plate is observed from a transparent visual window. When the pressure plate drops one scale, the lubrication is stopped.

[0004] The above scheme still has the following disadvantages: when lubricating the bearing, the oil output each time needs to be manually controlled by observing the scale through the transparent visual window. Manual visual observation can easily lead to inconsistent oil output, which is not conducive to regular lubrication of the bearing in the later stage. Utility Model Content

[0022] During use, by starting the electric push rod 16, the telescopic shaft of the electric push rod 16 extends and drives the pressing plate 25 to move downward, thereby squeezing the lubricating oil inside the oil storage tank 4. At this time, the pressing plate 25 drives the base 24 to move downward, so that the connecting rod 12 rotates and drives the sliding block 7 to slide inside the sliding hole 5 and approach each other. When the conductive sheet 10 and the conductive strip 11 are close to and in contact, the light bulb 15 is energized and lights up, thereby reminding the staff that the predetermined oil output has been reached, and when the pressing plate 25 moves downward, the internal lubricating oil of the oil storage tank 4 is The oil will enter the interior of the end cover 2 through the oil pipe 23 and lubricate the bearing 3.

[0025] In the present device, by starting the electric push rod 16, the telescopic shaft of the electric push rod 16 extends and drives the pressing plate 25 to move downward, thereby squeezing the lubricating oil inside the oil storage tank 4. At this time, the pressing plate 25 drives the base 24 to move downward, so that the connecting rod 12 rotates and drives the sliding block 7 to slide inside the sliding hole 5 and approach each other. When the conductive sheet 10 and the conductive strip 11 are close to and in contact, the light bulb 15 is energized and lights up, thereby reminding the staff that the predetermined oil output has been reached, and when the pressing plate 25 moves downward, the lubricating oil inside the oil storage tank 4 is squeezed out. The lubricating oil will enter the interior of the end cover 2 through the oil pipe 23 and lubricate the bearing 3. After the light bulb 15 is lit, the telescopic axis of the electric push rod 16 can be moved upward and reset. In this solution, the path of the two sliding blocks 7 approaching each other is the path of the pressure plate 25 moving downward, so that the depth of the pressure plate 25 moving downward each time is consistent, so that the amount of lubricating oil released is also consistent, and the light bulb 15 lights up after reaching the predetermined depth to remind the staff that the corresponding oil output has been reached. While the operation is convenient, it is also convenient for regular lubrication of the bearing 3.

[0026] By setting the plug 18, the staff can remove the plug 18 later, and add lubricating oil to the inside of the oil storage tank 4 through the oil inlet pipe 17. When the electric push rod 16 is damaged, the bolt 21 can be rotated out from the inside of the threaded hole 20, so as to separate the mounting strip 19 and the oil storage tank 4, so as to achieve the effect of disassembling the electric push rod 16 for repair or maintenance.
