Description

Automatic lubricating device for robot embroidery machine

technical field

The utility model relates to a lubricating oil supply device, in particular to an automatic lubricating device for a robot embroidery machine.

Background technique

During the embroidery process of the robot embroidery machine, the parts of the machine head reciprocate at high speed. If the parts of the machine head lack lubricating oil or the supply of lubricating oil is insufficient, the friction between the parts will increase, which will cause the temperature of the high-speed moving parts to rise. High and frictional noise increase, reducing the service life of the embroidery machine. At present, the lubrication of robot embroidery machines is mostly done manually. After the embroidery machine has been working for a period of time, the operator injects lubricating oil into each oil injection hole with an oil pot. The amount of oil injection depends on the experience of the operator. If the amount of oil injection is insufficient, the lubrication effect will not be good. If the amount of oil injection is too large, the lubricating oil will overflow, contaminate the product, affect the quality of embroidery products or lead to waste products.

Contents of the invention

The purpose of the utility model is to provide an automatic lubricating device for a robot embroidery machine which can automatically detect and supply lubrication without excessive lubricating oil overflowing.

The technical solution of the utility model is: an automatic lubricating device for a robot embroidery machine, including an oil storage cylinder, a controller, and a sensor. The solenoid valve controlled on and off by the controller is connected with the air supply system, and the sensor installed at the head of the embroidery machine is connected with the controller.

The sensors installed on the head of the embroidery machine are temperature sensors and noise sensors.

A filter membrane is arranged in the oil storage tank.

A liquid level sensor is arranged in the oil storage cylinder and is electrically connected with the controller.

The automatic lubricating device provided by the utility model collects signals by setting temperature and noise sensors at the head of the embroidery machine, and sends the signals to the controller, and then the controller judges the lubrication status of the moving parts of the machine head, and outputs to control the solenoid valve. The on-off electrical signal realizes the automatic supply of lubricating oil to the head of the embroidery machine and the control of the injection amount of lubricating oil.

The utility model is characterized in that it realizes the automatic control of supplying lubricating oil to the embroidery machine, so that the machine is always in a good lubricating state, and solves the problems of inconvenient manual injection, untimely injection and difficulty in controlling the injection dose, resulting in insufficient injection volume and overflow. The service life of the moving parts of the embroidery machine is reduced, and the wear rate is reduced, thereby ensuring the stability of the embroidery quality of the embroidery machine.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figure 1, the automatic lubrication device of the robot embroidery machine is mainly composed of an oil storage tank, an air supply system, a temperature sensor, a noise sensor and a controller. The temperature sensor and the noise sensor are installed on the head of the embroidery machine, and send the sound and temperature change signals of the head when it is working to the controller. The sealed oil storage cylinder is composed of a cylinder body 1 and a top cylinder cover 2 threadedly connected thereto. The oil storage cylinder cover is provided with an oil filling port 3 and an air inlet 4, and the oil filling port is used to add lubricating oil to the oil storage cylinder. The air inlet communicates with the air supply system through the electromagnetic valve 5 and the air inlet pipe 10, and the compressed air enters the oil storage cylinder through the electromagnetic valve and the air inlet. The top in the oil storage cylinder has a filter membrane 6 for filtering lubricating oil and compressed air entering the cylinder. A liquid level sensor 7 electrically connected to the controller is installed on the inner wall of the oil storage cylinder. When the lubricating oil liquid level in the oil storage cylinder is lower than a certain value, the controller will give an alarm and it is necessary to add lubricating oil in the oil storage cylinder. An oil outlet 8 is arranged at the bottom of the oil storage cylinder body, and the oil outlet communicates with the oil injection hole on the embroidery machine head through an oil delivery pipe 9 .

The utility model is based on the two physical parameters of temperature and friction noise for the automatic oiling of the head of the embroidery machine. In order to obtain the temperature and friction noise parameters, a temperature sensor and a noise sensor are respectively installed on the outside of the high-speed moving parts of the embroidery machine head. In this way, when the embroidery machine head lacks lubricating oil, the temperature rise and noise increase of the parts caused by the increased friction are collected by the temperature sensor and the noise sensor respectively, and the collected values are compared with the values collected when the lubrication is normal. When the value is greater than the normal value, oil will be filled automatically. The following describes the control principle and implementation process in conjunction with the control flow chart 2. During the embroidery process of the embroidery machine, the temperature collected by the temperature sensor installed outside the high-speed moving parts of the embroidery machine head is input to the controller, and the temperature stored in the controller is normal. If the collected temperature value is greater than the normal value, the controller will open the solenoid valve, and the compressed air will enter the oil storage tank through the solenoid valve. In the oil injection hole of the moving parts of the machine head. The amount of oil injected is determined by the opening time of the solenoid valve (the pressure change has been compensated by the controller), changing the time of "delay I" means changing the amount of oil injected, and this time can be set.

The noise sensor collects mechanical vibration noise, and the collected noise signal is input to the controller, and the processing method of the signal is the same as that of the temperature signal.

After the controller completes the oil injection control, it needs to wait for the "delay II" time, because after the lubricating oil is injected, the temperature rise of the moving parts and the mechanical vibration noise will not drop immediately, the "delay II" is to avoid excessive Inject lubricant. The oil injection amount of the device is determined by the pressure of the gas storage tank and the opening time of the solenoid valve, and the pressure change is compensated by the controller, so the oil injection amount is only determined by the opening time of the electromagnetic valve.
