Embodiment 1

[0037] basically as attached figure 1 , figure 2 and image 3 Shown: a control system for micro-grinding, including a frame, a grinding host 1 and a negative pressure system, wherein the grinding host 1 includes a host motor 11, a host shell 12, a top cover 13, a hollow shaft 14 and a tool rest Assembly, in which the host motor 11 and the host shell 12 are both fixed on the frame, the hollow shaft 14 is rotatably connected in the host shell 12, and the tool holder assembly includes a plurality of sharpeners 15 fixed on the hollow shaft 14 and a fixed The grinding block 16 on the inner wall of the main body casing 12 , wherein the upper surface of the grinding knife 15 is in contact with the lower surface of the grinding block 16 .

[0038] A first belt transmission mechanism is connected between the hollow shaft 14 and the host motor 11, wherein the first belt transmission mechanism includes a first driving pulley 17, a first driven pulley 18 and a first belt 19, and the fi...

Embodiment 2

[0053] The difference from Example 1 is that the combination Figure 4 As shown, the feeding shaft 33 is horizontally connected in the barrel 31 through the bearing and the bearing seat 90, wherein the bearing seat 90 is fixed on the right end of the barrel 31, and the right end of the barrel 31 is provided with a connecting hole 91, and due to the analysis When the main engine is working, there is a large negative pressure wind entering, in order to reduce the loss of lubricating oil in the bearing seat 90 (flow into the material barrel 31 due to the large negative pressure), thereby affecting the quality of the material.

[0054] A plugging cylinder 92 is arranged in the bearing seat 90 close to the connecting hole 91. The plugging cylinder 92 has a porous structure, that is, it is made of porous material. The plugging cylinder 92 is sleeved on the feeding shaft 33, and the plugging cylinder 92 The outer diameter is larger than the diameter of the connecting hole 91, and the...

Embodiment 3

[0056] The difference from Embodiment 1 is that the bottom of the top cover 13 is integrally formed with a conical protrusion, the conical protrusion is large at the top and small at the bottom, and the part of the conical protrusion is located in the air hood 22, so that the conical protrusion is arranged in this way. A guide channel is formed between the raised side wall and the inner wall of the airflow hood 22 , so that the powder can more easily enter the inside of the airflow hood 22 and adhere to the inner wall of the airflow hood 22 under the action of centrifugal force.

Abstract

The invention relates to the technical field of grinding control systems, and specifically discloses a control system for micro-grinding, comprising a frame, a grinding host, an analysis host, a feeder and a negative pressure system. The analysis host includes an analysis motor, an air flow a cover, a rotating shaft and a discharge pipe; the feeder is communicated with the main grinding machine, and the feeder includes a material barrel, a silo, a feeding unit and a driving unit, and the driving unit includes a feeding motor; the negative pressure system includes a negative pressure system. Compressor and dust collector; analysis motor, feeding motor and negative pressure fan are all connected with electric control unit, each electric control unit includes PLC and frequency converter, and the frequency converter in each electric control unit controls the analysis motor respectively , the operation of feeding motor or negative pressure fan. Due to the introduction of the electronic control unit in this patent, the automatic adjustment of the analysis motor, the feeding motor and the negative pressure fan is controlled by the PLC to achieve a substantial improvement in the production efficiency and the quality of the titanium dioxide is also greatly improved. .

Description

technical field [0001] The invention relates to the technical field of grinding powder control systems, in particular to a control system for micro-grinding powder. Background technique [0002] At present, in the industrial production of titanium dioxide, it is necessary to use grinding equipment to pulverize and grind the titanium dioxide coarse material. The grinding equipment usually includes a grinding host, an analysis host, a feeder and a negative pressure system. The analysis host is located in the grinding Above the main machine, and the analysis main machine is connected to the negative pressure system. The grinding main machine is mainly for pulverization and grinding. The feeder is responsible for supplying coarse materials to the grinding main machine, and at the same time, under the action of the negative pressure system, the ground fine powder is The material enters the analysis host, and the powder with the particle size that meets the requirements is obtaine...
