Description

Technical Field

[0001] The utility model relates to the technical field of oil pumps, in particular to a novel oil pump for embroidery machines. Background Art

[0002] The machine head and rotary hook are important components of a computerized embroidery machine. To reduce wear and extend their service life, they need to be lubricated regularly or during work breaks. Currently, the lubrication of the machine head or rotary hook is generally done manually or with an external oil sprayer. However, this oil spraying method has a poor lubrication effect and wastes a lot of lubricating oil. In addition, the excess lubricating oil during the lubrication process can easily splash onto other components or the bobbin thread, dirtying the machine equipment or the workplace. In addition, the machine head and rotary hook each require an oil sprayer, which takes up machine space. Utility Model Content

[0003] In order to solve the above defects, the utility model provides a new type of embroidery machine oil pump, which solves the problems of lubrication timing and quantity and machine space occupation.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A novel embroidery machine oil pump includes a PLC controller, an oil pump, and an oil injection assembly. The oil pump includes a housing cover, an oil storage box, a pressure sensor, and an oil level switch. The housing cover and the oil storage box are tightly connected and matched. The pressure sensor and the oil level switch are arranged on the housing cover and extend into the oil storage box to monitor the pressure and oil level of the oil stored in the oil storage box and provide feedback to the PLC controller.

[0006] The oil injection assembly is connected to the oil pump, and includes an electric ball valve, an oil pipeline, an upper refueling outlet and a lower refueling outlet. One end of the electric ball valve is connected to the end of the oil pipeline, and the upper refueling outlet and the lower refueling outlet are connected to the other end of the electric ball valve. The electric ball valve is connected to the PLC controller signal. The PLC controller can control the medium in the oil pipeline to be sprayed from the upper refueling outlet or the lower refueling outlet by sending a signal to the electric ball valve.

[0007] Furthermore, a refueling port is provided on the shell cover, and a refueling cap is provided on the refueling port.

[0008] Furthermore, the shell cover is provided with a pressure gauge for visually observing the internal pressure of the oil storage box.

[0009] Furthermore, a waterproof interface for connecting to a power source is provided on one side of the shell cover.

[0010] Furthermore, a mounting fixture is fixedly connected to the shell cover, a mounting hole is opened on the mounting fixture, and the mounting hole is a gourd-shaped hole.

[0011] The beneficial effects of adopting the above technical solution are:

[0012] The PLC controller presets the refueling amount and refueling cycle. By rotating the direction of the ball in the electric ball valve, different medium flow channels are formed, and the appropriate amount of oil is precisely sprayed out from the upper refueling outlet or the lower refueling outlet on time and in quantity. This can provide regular and quantitative refueling and lubrication to the designated parts of the machine head or rotary hook. This automated control method not only improves the accuracy of refueling, but also reduces the complexity and potential errors of manual operation. It accurately and automatically completes the refueling needs of the machine head or rotary hook separately. At the same time, the electric ball valve is used to control the flow direction. One oil pump can play the function of two oil pumps, thereby reducing equipment costs for customers and saving space on the machine. BRIEF DESCRIPTION OF THE DRAWINGS
