Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: an automatic lubricating oil filling machine, including a filling cabinet 1, the filling cabinet 1 includes a cabinet body 101, a filling channel is arranged in the middle of the cabinet body 101, one side of the filling channel is located inside the cabinet body 101 and an installation cavity is arranged, a filling device 2 is arranged in the installation cavity, the filling device 2 includes an oil storage tank 201, the oil storage tank 201 is fixedly installed on the inner wall of the bottom of the installation cavity, a through hole is arranged on one side of the upper surface of the oil storage tank 201, and an oil extraction pipe 202 is fixedly connected to the through hole, and one end of the oil extraction pipe 202 Extending to the inside of the oil storage tank 201, the oil extraction pipe 202 is connected to the oil pump 203, the other end of the oil extraction pipe 202 is connected to one end of the telescopic hose 204, the other end of the telescopic hose 204 is connected to one end of the oil guide pipe 205, the oil guide pipe 205 is fixedly installed on the filling height adjustment mechanism 3, the other end of the oil guide pipe 205 is connected to the filling head 206, a conveying device 4 is provided in the filling channel, and a position sensor is fixedly installed on the inner wall of one side of the filling channel at a position corresponding to the filling head 206.

[0023] See also Figure 1 The cabinet body 101 has symmetrically distributed operating doors 102 rotatably mounted on both ends of one side surface, and each operating door 102 has a visual window 103 disposed on one side surface.

[0024] By arranging the filling device 2 and the conveying device 4 in a semi-enclosed filling channel, the noise and splashing oil stains generated during the operation of the equipment can be relatively reduced, and the situation where external dust enters the filling bottle can also be relatively reduced.

[0025] See also Figures 2 to 5 The filling height adjustment mechanism 3 includes a guide slot 301 provided on the inner wall of one side of the light-filling channel, a slider 302 is slidably installed in the guide slot 301, a through slot is provided on the surface of one end of the slider 302, the oil guide pipe 205 is fixedly installed in the through slot, and the slider 302 is connected to the lifting mechanism.

[0026] The lifting mechanism drives the slider 302 to slide up and down in the guide slot 301, so that the height of the oil guide pipe 205 and the filling head 206 can be adjusted, so that the height can be flexibly adjusted according to the actual height of the filling bottle, reducing limitations in use.

[0027] Furthermore, the lifting mechanism includes a connecting block 303, which is fixedly mounted on one side surface of the slider 302. A threaded hole is penetrated through the top surface of the connecting block 303, in which an adjusting screw 304 is threadedly connected.

The driving motor 305 is fixedly mounted on the top surface of the cabinet 101, and one end of its output shaft extends to the inside of the mounting cavity through the extension hole.

[0028] When the driving motor 305 is started to drive the adjusting screw 304 to rotate, since the connecting block 303 is threadedly connected to the adjusting screw 304 through the threaded hole and is fixedly connected to the slider 302 at the same time, the slider 302 can slide upward or downward in the guide groove 301 according to the rotation direction of the adjusting screw 304, thereby driving the oil guide pipe 205 and the filling head 206 to adjust the height.

[0029] Furthermore, a flow meter 207 and a solenoid valve 208 are connected in sequence between one end of the oil guide pipe 205 and the filling head 206 .

[0030] The filling capacity can be precisely controlled by providing the flow meter 207 and the solenoid valve 208 to ensure the accuracy of the capacity during automatic filling of the lubricating oil.

[0031] Furthermore, a heat-conducting cover 209 is fixedly sleeved outside the oil-conducting pipe 205 , and electric heating plates 210 are fixedly connected to the top, bottom and both side surfaces of the heat-conducting cover 209 .

[0032] By starting the electric heating plate 210 to heat the electric heating plate 210 from all sides, the electric heating plate 210 transfers the heat to the oil guide pipe 205 inside it, thereby heating the lubricating oil inside the oil guide pipe 205, thereby improving the fluidity of the lubricating oil by increasing the temperature of the lubricating oil, thereby improving the efficiency of automatic filling.

[0033] Furthermore, an oil filling port 211 is provided on the other side of the top surface of the oil storage tank 201 , and a guide slope 212 is provided on the bottom inner wall of the oil storage tank 201 , and the lower end of the guide slope 212 is close to the bottom end of the oil extraction pipe 202 .

[0034] Lubricating oil can be added to the oil storage tank 201 through the oil filling port 211, and the guide slope 212 provided at the bottom of the oil storage tank 201 can make the internal lubricating oil flow to the bottom end of the oil extraction pipe 202 to ensure the stability of oil supply.

[0035] Working principle: add lubricating oil into the oil storage tank 201, start the driving motor 305 according to the height of the filling bottle, drive the slider 302 to slide in the guide slot 301 by adjusting the rotation of the screw 304 to adjust the height of the oil guide pipe 205 and the filling head 206, place the filling bottles on the conveying device 4 at a predetermined interval and convey them to the filling channel, and when the filling bottles reach the bottom of the filling head 206, the position sensor is triggered, and the position sensor converts the signal into an electrical signal to start the oil pump 203 to extract the lubricating oil inside the oil storage tank 201 through the oil extraction pipe 202, and the lubricating oil enters the telescopic hose 204 through the oil extraction pipe 202, and enters the oil guide pipe 205 through the telescopic hose 204, and the oil guide pipe 205 and the filling head 206 are connected to the flow meter 207 The solenoid valve 208 can calculate the flow rate of the passing lubricating oil. When the flow rate reaches the preset filling capacity, the solenoid valve 208 closes the oil circuit. After completing a filling work, the conveying device 4 transports the subsequent empty filling bottles to the bottom of the filling head 206 for filling. The heat conductive cover 209 and the electric heating plate 210 arranged outside the oil guide pipe 205 can heat the lubricating oil in the oil guide pipe 205 to improve its fluidity and improve the filling efficiency. By setting the oil delivery pipeline as a fixed oil extraction pipe 202 and a movable oil guide pipe 205 two-end structure, and connecting the two through a telescopic hose 204, and connecting the oil guide pipe 205 to the filling height adjustment mechanism 3, the use limitations can be reduced during the lubricating oil filling work, and more filling bottles of different height specifications can be adapted.

[0036] It should be noted that the specific models and specifications of the position sensor, oil pump 203, flow meter 207, solenoid valve 208, electric heating plate 210, drive motor 305 and conveying device 4 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0037] The power supply and principles of the position sensor, oil pump 203, flow meter 207, solenoid valve 208, electric heating plate 210, drive motor 305 and conveying device 4 are clear to those skilled in the art and will not be described in detail herein.

[0038] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
