[0028] In the embodiment, the sum of the cross-sectional areas of all the liquid outlets 23 is smaller than the cross-sectional area of the liquid inlet 21. After the lubricating oil passes through the liquid distribution cavity 22, it is squeezed out from two or more liquid outlets, and the cross-sectional area change of the liquid inlet and the liquid outlet of the liquid distributor is utilized to ensure that the oil pressure of the lubricating oil increases when the lubricating oil is divided from the liquid outlet, so as to ensure the lubricating effect.

[0029] In the embodiment, the air inlet 11 is provided with an electromagnetic valve 13 controlled by the control system of the cutter to open and close at regular time intervals, and the electromagnetic valve 13 is used to control the air inlet amount of the compressed air.

Specifically, the liquid outlet 23 is provided with an internal thread, a quick plug connector is connected through the thread, one end of the oil pipe is inserted into the quick plug connector, and the other end is connected with the oil hole of the shaft sleeve.

[0031] The working principle of the utility model is as follows:

When the electromagnetic valve 13 is closed, the pressure in the oil tank 1 is no longer increased, and the medium pressure of the oil tank 1 and the distributor 2 tends to be balanced, and the oil no longer enters the distributor 2 due to the pressure difference, thereby realizing the closing of the oil supply module.

[0033] During the oil supply process, the compressed air increases the internal pressure of the oil tank 1 to extrude the lubricating oil, and since a closed rigid oil tank and a high-pressure oil line are used, the oil pressure of the lubricating oil can be stabilized, so that the lubricating oil entering the shaft sleeve has a certain oil pressure, so that the lubrication is more thorough and can reach the distal end of the lubricated part. The pressure balance valve in the oil supply module makes the system oil supply more stable and accurate. In addition, by using the cross-sectional area change of the distributor 2, the oil pressure of the lubricating oil is increased when it is divided from the liquid outlet, and the lubrication effect is guaranteed.
