Utility Model Content

[0004] The purpose of the present application is to provide a pneumatic self-lubricating device for a swing arm spraying device to solve at least one of the above-mentioned technical problems.

[0005] In order to solve the above technical problems, the present application provides a pneumatic self-lubricating device for a swing arm spraying device, comprising a pneumatic drive assembly, an oil cup assembly, a flow diversion assembly, and a first oil pipe;

[0006] The flow splitting assembly includes a distribution valve, a joint, a grease injection nozzle, and a second oil pipe connecting the joint and the grease injection nozzle.

[0008] The pneumatic drive assembly is used to drive the cam to rotate so as to drive the plunger pump to operate;

[0009] In the above implementation process, this scheme uses compressed air as the power, and the cylinder drives the plunger oil pump to output high-pressure lubricating oil to the distribution valve. The distribution valve uses the lubricating oil pressure as the power to distribute the lubricating oil to each pipeline in sequence like a "revolver". Repeating the cycle within a predetermined time allows the lubricating oil in each pipeline to overflow from the oiling nozzle and reach the lubrication points of the device for lubrication; it can distinguish and execute different lubrication amounts for each lubrication point, and under the cooperation of pneumatic pressure, it can lubricate to the most tightly sealed position of the bearing, with high lubrication reliability, which effectively improves the lubrication effect of the swing arm spraying device, effectively replaces the workload of manual lubrication and maintenance, and effectively saves manpower.

[0012] The output end of the cylinder is connected to the cam and is suitable for driving the cam to rotate;

[0013] In the above implementation process, when the pneumatic self-lubricating device starts lubrication, the first output port of the control box outputs compressed air source to control the working stroke of the cylinder: the first air inlet of the cylinder takes in air, the cylinder pushes the cam to rotate, and the cam pushes the plunger pump to pump oil; the second output port of the control box outputs compressed air source to control the return stroke of the cylinder: the second air inlet of the cylinder takes in air, the cylinder returns, and the cam and the plunger pump return. The first output port and the second output port of the control box alternately output compressed air source, and the cylinder working stroke and return stroke cycle alternately to achieve continuous oil pumping by the plunger pump.

[0014] Preferably, the pneumatic control box includes a timer, and when the timer enters a preset time point, the pneumatic control box drives the cylinder to move;

[0015] In the above implementation process, when the timer enters the preset time point or the countdown ends, the pneumatic control box is controlled to start the cylinder, and then the above self-lubrication procedure is repeated to realize regular and timed self-lubrication of the device. Automatic lubrication can be achieved without real-time monitoring by personnel, thereby ensuring long-term stable operation of the swing arm spraying device.

[0016] Preferably, the joint, the oil injection nozzle and the second oil pipe are provided with ten respectively;

[0017] In the above implementation process, the joint, the oiling nozzle and the second oil pipe can be understood as a group of oiling units. The ten groups of oiling units can sequentially lubricate multiple lubrication points such as the nut and screw lifting mechanism of the swing arm spraying device, the worm gear swing arm rotating mechanism, the storage barrel gear rotating mechanism, and the bearings.

[0018] Preferably, the pneumatic control box is provided with a first adjusting knob and a second adjusting knob; the first adjusting knob is used to control the time interval of the periodic start of the cylinder, and the second adjusting knob is used to control the single oil injection time;

[0019] In the above implementation process, through the cooperation of the first adjusting knob and the second adjusting knob, the pneumatic self-lubricating device can automatically start lubrication at a set time without the need for personnel management. The regular number of days and the duration of each lubrication can be adjusted using the adjusting knob to adapt to the lubrication requirements of the device in different environments.

[0020] Preferably, the pneumatic control box is further provided with a manual start button and a manual stop button, and the manual start button is suitable for directly driving the cylinder to start and setting the timer to zero;

[0021] The manual stop button is used to drive the cylinder to drive the plunger pump to stop and reset the timer;

[0022] In the above implementation process, each time the manual start button is pressed, the pneumatic self-lubricating device automatically performs lubrication and automatic stop according to the original single self-lubricating time, and the regular start date is reset. When the manual stop button is pressed, the device stops lubrication and resets the regular start date.

[0023] Preferably, the first oil pipe and the second oil pipe are pressure-resistant oil pipes.

[0024] Compared with the prior art, the beneficial effects of the present application are as follows: the present solution uses compressed air as the motive force, and the cylinder drives the plunger oil pump to output high-pressure lubricating oil to the distribution valve. The distribution valve uses the lubricating oil pressure as the motive force to distribute the lubricating oil to each pipeline in sequence like a "revolver". The cycle is repeated within a predetermined time so that the lubricating oil in each pipeline overflows from the oiling nozzle to lubricate each lubrication point of the device. It can distinguish and execute different lubrication amounts for each lubrication point, and under the cooperation of pneumatic pressure, it can lubricate to the most tightly sealed position of the bearing, with high lubrication reliability. It effectively improves the lubrication effect of the swing arm spraying device, effectively replaces the workload of manual lubrication and maintenance, and effectively saves manpower.

[0042] In the above scheme, the scheme uses compressed air as the power, and the cylinder 12 drives the plunger oil pump to output high-pressure lubricating oil to the distribution valve 31. The distribution valve 31 uses the lubricating oil pressure as the power to distribute the lubricating oil to each pipeline in sequence like a "revolver". Repeat the cycle within a predetermined time to make the lubricating oil in each pipeline overflow from the oiling nozzle 34 to lubricate each lubrication point of the device; it can distinguish and perform different lubrication amounts for each lubrication point, and under the cooperation of pneumatic pressure, it can lubricate to the most tightly sealed position of the bearing, with high lubrication reliability, which effectively improves the lubrication effect of the swing arm spraying device, effectively replaces the workload of manual lubrication and maintenance, and effectively saves manpower.

[0049] Specifically, the pneumatic control box 11 includes a timer (not shown in the figure). When the timer enters a preset time point, the pneumatic control box 11 drives the cylinder 12 to operate;

[0050] In the above scheme, when the timer enters the preset time point, or when the countdown ends, the pneumatic control box 11 starts to start the cylinder 12, and then repeats the above-mentioned self-lubricating procedure to achieve regular and timed self-lubricating work of the device.

[0057] Furthermore, the manual stop button 112 is used to drive the cylinder 12 to drive the plunger pump 23 to shut down and reset the timer;
