The present embodiment provides an oil application device, and referring to fig. 1 and 2, it is shown in a schematic structural view of the oil application device in a first state and a second state in the present embodiment, respectively. The oil spraying device comprises: the oil pump comprises a cavity 10 and a piston 20, wherein the piston 20 is arranged in the cavity 10 to form an oil cavity 11 inside the cavity 10, the piston 20 can move along the length direction of the cavity 10 to change the volume of the oil cavity 11, and the oil cavity 11 is provided with an oil inlet 13 and an oil outlet 14. The oil inlet 13 is used for connecting an oil storage device such as an oil tank to suck oil in the oil tank into the oil cavity 11, and the oil outlet 14 is used for connecting the spray head assembly to convey the oil in the oil cavity 11 to the spray head assembly for oil spraying. The oil injection quantity in each time is the volume of the oil stored in the oil cavity 11, the volume is determined by the moving distance of the piston 20, the longer the moving distance of the piston 20 is, the more oil can be sucked from the oil tank, and the larger the oil injection quantity in each time is, so that the oil injection quantity of the oil spraying device can be determined by the moving distance of the piston 20, and the quantitative oil injection of the oil spraying device is realized. The movement of the piston 20 can be achieved in various ways, for example, directly pushing by a piston rod, pushing by pressure oil, pushing by pressure gas, etc., and the present embodiment only describes the embodiment of pushing by pressure gas, and please refer to the following description.
Further, the maximum volume of the oil chamber 11 is adjustable, and specifically, the following settings can be adopted:
the chamber body 10 includes a chamber body 10a and an adjusting body 10b connected to each other, and the adjusting body 10b can adjust a position relative to the chamber body 10a to adjust a volume of the oil chamber 11. The adjustment of the volume of the oil chamber 11 by the adjusting body 10b is to adjust the oil absorption amount of the piston 20, and the moving distance of the piston 20 is generally set to be constant, so as to ensure that the oil injection amount is equal, and when the oil injection amount needs to be changed, the maximum volume of the oil chamber 11 can be changed by the adjusting body 10 b. The adjustment of the maximum volume of the oil chamber 11 can also take other forms, for example: by varying the amount of movement of the piston. The maximum volume of the oil chamber 11 referred to herein can be understood with reference to fig. 1, in which fig. 1, the maximum volume of the oil chamber 11 when the piston 20 moves to the rightmost side within the movable range is shown.
The tip of chamber body 10a has the internal thread mouth, it has the external screw thread to adjust body 10b, it passes through to adjust body 10b the external screw thread closes soon in the internal thread mouth, in order to incite somebody to action chamber body 10a is sealed, it can change through self length of closing soon to adjust body 10b the volume of oil pocket 11. Of course, the chamber body 10a and the adjustment body 10b may also take other forms of connection, for example, by a plunger-like structure.
Preferably, the oil outlet 14 is arranged on the adjusting body 10b, of course, the oil outlet 14 may be arranged at other positions for facilitating oil outlet, such as: on the side wall of the end of the chamber body 10 a.
The embodiment for the pressure gas to push the piston 20 to move is as follows:
an air cavity 12 is formed inside the cavity 10, the air cavity 12 and the oil cavity 11 are respectively located at two sides of the piston 20, and the piston 20 can move along the length direction of the cavity 10 to simultaneously change the volumes of the oil cavity 11 and the air cavity 12. That is, the piston 20 divides the chamber 10 into the oil chamber 11 and the air chamber 12 which are sealed from each other. Movement of the piston 20 may be achieved by increasing the pressure of the gas within the gas chamber 12. Preferably, the air chamber 12 has an air inlet 15, the air inlet 15 being adapted to be connected to a source of high pressure gas. The high-pressure gas source inputs high-pressure gas into the gas cavity 12 to push the piston to move the compression oil cavity 11 for oil injection, and the high-pressure gas source outputs (sucks) the high-pressure gas out of the gas cavity 12 to push the piston to move to increase the volume of the oil cavity 11 for oil absorption.
After each oil injection, in order to clear the oil passage, the residual oil in the oil passage can be blown clean by gas. In particular, the device has a first channel 16, wherein, in a first state (shown in fig. 1), the oil chamber 11 and the air chamber 12 are not in communication; in the second state (shown in fig. 2), the oil chamber 11 and the air chamber 12 communicate through the first passage 16. After the oil chamber 11 and the air chamber 12 are communicated through the first passage 16, the high-pressure gas in the air chamber 12 flows into the oil chamber 11, so that the oil chamber 11 and the residual oil in the oil path are purged, and the oil is prevented from being blocked.
Further, in order to achieve a better spraying effect of the oil in the oil chamber 11, the piston 20 may be arranged not to completely compress the oil chamber 11 to a zero space, that is, the oil chamber 11 always has a minimum volume, and specifically, the first passage 16 communicates the oil chamber 11 with the air chamber 12 after the piston 20 moves to a set position in a direction from the air chamber 12 to the oil chamber 11. In fig. 2, the oil chamber 11 is in a minimum volume state.
Further, the oil spraying device further comprises a guide rod 40 fixed in the cavity 10, the piston 20 is provided with an inner hole, the piston 20 is sleeved on the guide rod 40 through the inner hole, and the length direction of the guide rod 40 is arranged along the moving direction of the piston 20. The guide rod 40 can further guide the movement of the piston 20, so that the movement of the piston 20 is smoother.
Preferably, the first channel 16 opens in the guide bar 40 or in a side wall of the chamber 10. As shown in fig. 1-2, the first passage 16 is opened in the guide bar 40 so that the structural strength of the chamber 10 can be secured. Of course, it is also possible to provide two line connections in the side wall of the chamber 10 and then communicate via a line, i.e. the line here acts as the first channel 16.
Further, the oil spraying device further comprises a limiting part 42 arranged on the side wall of the guide rod 40 or the cavity 10, and the limiting part 42 is used for limiting the movable range of the piston 20. In fig. 1-2, the position-limiting portion 42 is provided on the guide bar 40, and those skilled in the art will understand that the position-limiting portion 42 can be provided at a corresponding position on the side wall of the chamber 10.
Referring to fig. 1, in the first state, the oil chamber 11 and the air chamber 12 are not communicated, and at this time, the high-pressure air entering the air chamber 12 from the air inlet 15 acts on the piston 20 to push the piston 20 to move, so as to compress the volume of the oil chamber 11, and the oil in the oil chamber 11 is output from the oil outlet 14. When the piston 20 moves a certain distance and reaches the second state, as shown in fig. 2, the oil chamber 11 is communicated with the gas chamber 12, at this time, the high-pressure gas in the gas chamber 12 flows into the oil chamber 11 through the first passage 16, and the oil liquid in the oil chamber 11 is mixed with the high-pressure gas to atomize the oil liquid, so that the oil injection effect can be improved, and the solidification of the oil liquid can be reduced, thereby avoiding the oil path blockage.
Alternatively, one end of the guide bar 40 is fixed to the air inlet 15, and the guide bar 40 has a second passage 41 communicating the air inlet 15 with the air chamber 12. At this time, the guide bar 40 is fixed at the center of the end portion in the chamber 10, and the position of the gas inlet 15 coincides with one end of the guide bar 40, so that the gas chamber 12 introduces the high pressure gas through the second passage 41. Of course, the gas inlet 15 may be provided at other positions of the chamber 10, so that the high-pressure gas is directly introduced from the gas inlet 15 without providing the second passage 41 in the guide bar 40.
Referring to fig. 3, in another embodiment, one end of the guide rod 40 is fixed to the oil outlet 14 of the adjusting body 10b, and the guide rod 40 has a third channel 43 communicating the oil outlet 14 with the oil chamber 11. At this time, the oil in the oil chamber 11 is output through the third passage 43. Because the adjusting body 10b can move relative to the cavity body 10a, the guide rod 40 can be driven to move (the moving direction is the length direction of the cavity body 10, namely the left-right direction or the horizontal direction in the drawing), and after the position of the guide rod 40 is changed, the position of the limiting part 42 is also changed, so that the movable space of the piston 20 can be adjusted, the maximum volume of the oil cavity 11 can be adjusted, the oil amount sucked or sprayed due to the movement of the piston at each time can be changed, and the control of the oil spraying amount of the oil spraying device is more flexible.
The bidirectional movement of the piston 20 can be changed by changing the flow direction of the high-pressure gas, but in order to make the movement of the piston 20 more flexible and controllable, a piston resetting component can be arranged in the cavity 10, and particularly, the oil spraying device also comprises a resetting component 30 arranged in the cavity 10, and the resetting component 30 is used for resetting the piston 20. Reset device 30 may take the following two configurations:
① the reset component 30 is located in the air chamber 12, the reset component 30 is an extension spring, one end of the extension spring is fixed on the chamber 10, the other end is fixed on the piston 20, ② the reset component 30 is located in the oil chamber 11, the reset component 30 is a compression spring.

During oil suction of the oil chamber 11, the controller controls the fluid valve 51 to be closed, so that oil in the oil tank 70 is sucked into the oil chamber 11 through the check valve 71 by the movement of the piston 20, during oil injection, the controller controls the fluid valve 51 to be opened, the piston 20 compresses the oil chamber 11, the oil is conveyed to the spray head assembly 50 from the oil outlet 14 through the fluid valve 51 to be sprayed, and due to the action of the check valve 71, when the piston 20 compresses the oil chamber 11, a passage from the oil chamber 11 to the oil tank 70 is closed. In the case where the oil application device has an air chamber 12, that is, in the embodiment where the movement of the piston is achieved by air pressure pushing, the oil application system further includes an air supply system 60 and a solenoid valve 61, the air supply system 60, the solenoid valve 61, and the air chamber 12 are sequentially communicated so that the air supply system 60 can deliver gas having pressure to the air chamber 12 through the solenoid valve 61, and the controller is electrically connected to the solenoid valve 61 to control the on-off state of the solenoid valve 61. Further, the air supply system 60 comprises an air compressor 62, an air storage tank 63 and a pressure reducing valve 64 which are sequentially communicated, wherein the pressure reducing valve 64 is communicated with the electromagnetic valve 61. The solenoid valve 61 is a three-way valve, a first passage of which is communicated with the pressure reducing valve 64, a second passage of which is communicated with the air chamber 12, and a third passage of which is open to the atmosphere.
According to fig. 4, the control method of the oil application system is as follows:
