[0022] Example 2

[0023] Reference Figure 2 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0024] In this embodiment, the control cabinet 5 includes a cabinet body 51 and a timer 52. The cabinet body 51 is located on the left side of the back side of the inner cavity of the placement cabinet 1 and is fixedly connected to the inner wall of the placement cabinet 1. The timer 52 is arranged on both sides of the front side of the grease filter 6.

[0025] The valve body 7 includes a hydraulic reversing valve 71 and a filter valve 72 , and both the hydraulic reversing valve 71 and the filter valve 72 are arranged on the front side of the grease filter 6 .

[0026] like Figure 2 As shown, the cabinet 51 is used to control the start and stop of each component, the timer 52 is used to control the start and stop time of the component, and the hydraulic reversing valve 71 and the filter valve 72 are used to adjust the input direction of the lubricating oil and filter the lubricating oil respectively.

[0027] Example 3

[0028] Reference Figure 2 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0029] In this embodiment, the oil pipeline 8 includes a first pipeline 81 and a second pipeline 82. One end of the first pipeline 81 is connected to the grease filter 6, and the other end of the first pipeline 81 passes through the outside of the storage cabinet 1 and is connected to the two-line distributor 9. One end of the second pipeline 82 is connected to the grease filter 6, and the other end of the second pipeline 82 is connected to the oil storage barrel 3.

[0030] The oil outlet pipeline 10 includes a hose 101 and a hard pipe 102 . The hard pipe 102 is located on both sides of the double-line distributor 9 and is connected to the double-line distributor 9 . The hose 101 is arranged on the surface of the hard pipe 102 .

[0031] like Figure 2 As shown, the first pipeline 81 and the second pipeline 82 cooperate to transport the lubricating oil in two ways, and the hose 101 and the hard pipe 102 cooperate to transport the lubricating oil to different lubrication points.

[0032] During use, when the timer 52 of the control cabinet 5 reaches the predetermined time, the electric lubrication pump 4 starts, and the lubricant is discharged from the oil outlet of the electric lubrication pump 4, passes through the grease filter 6 and reaches the hydraulic reversing valve 71, and then enters the first pipeline 81. At this time, the second pipeline 82 returns to the oil storage barrel 3 through the hydraulic reversing valve 71 and is in an unloading state. The grease in the first pipeline 81 pushes the piston in the double-line distributor 9 to move to one side. During the movement of the piston, the grease in the front of it will be pressed into the oil outlet pipeline 10 and reach the nozzle of the spray gun assembly. When all the pistons have completed the movement to one side, the pressure in the first pipeline 81 will rise sharply. At the hydraulic reversing valve 71, when the pressure in the first pipeline 81 rises to the set reversing pressure of the hydraulic reversing valve 71, the hydraulic reversing valve 71 performs a reversing action, so that the first pipeline 81 is connected to the oil storage barrel 3 through the hydraulic reversing valve 71 and is in an unloading state, while the second pipeline 82 passes through the hydraulic reversing valve 71 and the outlet of the electric lubrication pump 4. When the second pipeline 82 is connected, the system completes a working cycle. When the next cycle starts, the grease output by the electric lubrication pump 4 enters the second pipeline 82. Similarly, the grease in the second pipeline 82 pushes the piston in the double-line distributor 9 to move to the other side. During the movement of the piston, the grease in the front of it will be pressed into the oil outlet pipeline 10 and reach the nozzle of the spray gun assembly. When the piston in the double-line distributor 9 has finished moving to the other side, the pressure in the second pipeline 82 rises sharply. At the hydraulic reversing valve 71, when the pressure in the second pipeline 82 rises to the pressure set by the hydraulic reversing valve 71, the hydraulic reversing valve 71 performs a reversing action, so that the second pipeline 82 is connected to the oil storage barrel 3 through the hydraulic reversing valve 71 and is in a unloading state, while the first pipeline 81 is connected to the outlet of the oil storage barrel 3 through the hydraulic reversing valve 71. The system continuously realizes a working cycle process by alternately supplying oil through the first pipeline 81 and the second pipeline 82 above. When the number of cycle cycles reaches the value set by the cabinet 51, the electric lubrication pump 4 stops working.
