Description

Technical Field

[0001] This utility model relates to the field of automatic lubrication devices, and in particular to an automatic lubrication device for textile machines. Background Technology

[0002] Lead screws require metered oil supply. Traditionally, this is done manually and periodically. However, the lead screw in a textile machine is located deep inside the equipment, and manual oiling requires disassembling many parts, which is very troublesome. Electric oiling equipment, on the other hand, uses a motor to drive the screw, resulting in a large external size, high energy consumption, and a high failure rate.

[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0004] An automatic lubrication device for a textile machine includes a lead screw and a lead screw nut, wherein a basic oil injection nozzle is provided on the lead screw nut for supplying oil lubrication to the bearing assembled inside the lead screw nut;

[0005] It also includes an oil bottle and a controller disposed on the oil bottle, wherein the oil bottle is threadedly connected to a threaded connection seat disposed on the lead screw nut, and the threaded connection seat and the base oil nozzle are connected by a soft oil pipe, thereby allowing the lubricating oil in the oil bottle to be injected into the base oil nozzle.

[0006] Preferably, the oil bottle is provided with a piston body, which is sealed to the inner wall of the oil bottle and can move along the axis of the oil bottle to pressurize the lubricating oil in the oil bottle and make it enter the basic oil injection nozzle. The cavity on the left side of the piston body in the oil bottle is under negative pressure.

[0007] Preferably, the controller includes a passage for air intake and a solenoid valve sealed within the passage, and also includes a power supply and control integrated board for powering the solenoid valve and wireless control.

[0008] Preferably, the oil bottle is equipped with a spring, which is used to push the piston towards the lubricating oil end to apply pressure. Since the cavity where the spring is located is a sealed structure, the spring cannot deform when the solenoid valve in the controller is closed.

[0009] Preferably, the controller has a pressure regulating chamber with two channels, one of which connects to the outside and the other to a connection port on the controller. The connection port is connected to the tail end of the oil bottle. In operation, the second solenoid valve is first opened to balance the air pressure in the pressure regulating chamber and the oil bottle, making them both negative pressure. Then, the second solenoid valve is closed and the first solenoid valve is opened to draw outside air into the pressure regulating chamber to bring its pressure to the standard. Then, the second solenoid valve is opened again, so that the negative pressure chamber in the oil bottle receives a fixed amount of air. As a result, the piston can move under the action of the spring, and the movement distance is the same each time, achieving a fixed oil supply effect.

[0010] Preferably, the connecting port and the oil bottle are connected by a threaded seal.

[0011] The advantages and positive effects of this utility model are:

[0012] 1. The control structure is much smaller than that of traditional servo motors and screw drive devices, which makes the equipment more compact and efficient. The same equipment size allows for a larger oil filling chamber, resulting in lower operating noise, lower energy consumption, and more accurate oil supply per cycle. Attached Figure Description

[0024] Preferably, the oil bottle 14 is provided with a piston body 22. The piston body 22 is sealed to the inner wall of the oil bottle 14 and can move along the axis of the oil bottle 14 to pressurize the lubricating oil 23 in the oil bottle 14 and make it enter the basic oil nozzle 12.

[0025] Preferably, the controller 15 has a passage for air intake and a solenoid valve is sealed within the passage. It also includes a power supply and control integrated board 17 for powering the solenoid valve and for wireless control.

[0026] Preferably, the oil bottle 14 is provided with a spring 21, which is used to push the piston body 22 toward the lubricating oil 23 end to apply pressure. Since the cavity where the spring 21 is located is a sealed structure, the spring 21 cannot deform when the solenoid valve in the controller 15 is closed.

[0027] Preferably, the controller 15 has a pressure regulating chamber 16, which is equipped with two channels, one of which is connected to the outside and the other is connected to a connection port 20 on the controller 15. The connection port 20 is connected to the tail end of the oil bottle 14.

Then the second solenoid valve 18 is closed and the first solenoid valve 19 is opened to draw outside air into the pressure regulating chamber 16 to make its air pressure standard. Then the second solenoid valve 18 is opened again, so that the negative pressure chamber in the oil bottle 14 receives a fixed amount of air. As a result, the piston 22 can move under the action of the spring 21, and the movement distance is the same each time to achieve a fixed oil supply effect.
