Description

Technical Field

[0001] The present invention relates to the technical field of oiling equipment, and in particular to an online oiling system based on CM and PM three-axis linkage. Background Art

[0002] An oiler is a device used to apply lubricants or preservatives to the surface of a workpiece, and plays a vital role in the industrial application industry. The oiler is mainly composed of an oil applicator, a conveying system, a control system, and a transmission device. Its working principle is to deliver the lubricant to the oil applicator through the conveying system, and then evenly apply the lubricant to the surface of the workpiece through the transmission device. When using an oiler, you need to pay attention to the selection of lubricants to avoid damage to the workpiece and ensure the normal maintenance and care of the equipment.

[0003] Usually, there is air inside the delivery pipeline of the oiler, and the existing oiler cannot exhaust the gas in the delivery pipeline. When the oil in the oil tank is drawn into the delivery pipeline, it will mix with the air so that the sprayed oil contains gas, causing the paint or lubricating oil sprayed on the workpiece surface to form bubbles, resulting in uneven spraying on the workpiece surface and unstable spray layer structure. Summary of the invention

[0004] The purpose of the present invention is to provide an online oiling system based on the three-axis linkage of CM and PM, which can solve the problem that the existing oiling machine cannot empty the gas in the conveying pipeline.

[0005] The objective of the present invention is achieved through the following technical solutions: A three-axis online oiling system based on CM and PM linkage includes an oil storage barrel, a diaphragm pump, a filter, a first pressure-stabilizing valve, a heater and a flow meter connected in sequence through a braided tube; it also includes a heating block and a water curtain valve; the heating block has an oil inlet and an oil return port, one end of the oil inlet of the heating block is connected to the flow meter through a Teflon tube, and the other end of the oil inlet of the heating block is connected to the water curtain valve through a Teflon tube, and the oil is introduced into the heating block and heated and then sprayed out by the water curtain valve; one end of the oil return port of the heating block is connected to the water curtain valve through a Teflon tube, and the other end of the oil return port of the heating block is connected to a three-way valve through a Teflon tube, and one end of the three-way valve is connected to the oil storage barrel through the Teflon tube; the oil flows back to the heating block from the water curtain valve, flows out from the oil return port of the heating block, flows back to the oil storage barrel through the three-way valve, and carries the gas in the oiling system into the oil storage barrel.

[0006] Preferably, an accumulator is installed on the diaphragm pump; and a second pressure-stabilizing valve is connected to the oil outlet of the diaphragm pump.

[0007] Preferably, the three-way valve is connected to the oil inlet of the diaphragm pump, and a circulation valve and a back pressure valve are connected between the three-way valve and the diaphragm pump through a Teflon tube; after the oil returns from the oil heating block, it flows into the diaphragm pump again through the three-way valve, the circulation valve and the back pressure valve in sequence.

[0008] Preferably, the oil inlet and oil return port of the heating block are both provided with manual ball valves; the bottom oil discharge port of the filter is also provided with a manual ball valve, and is connected to the oil storage barrel through a braided tube; during maintenance, the manual ball valve is opened to discharge the oil into the oil storage barrel.

[0009] Preferably, a float level gauge is provided in the oil storage barrel for detecting the liquid level of the liquid inside the oil storage barrel.

[0010] Preferably, the oiling system is also provided with a controller, and the controller controls the operation of the oiling system.

[0011] Preferably, the three-way valve is a manual three-way valve, and the operating state of the oiling system is switched by manually controlling the closing and opening of the two outlets of the three-way valve.

[0012] The inner diameter of the braided tube is 6 mm; the inner diameter of the Teflon tube is 4 mm.

[0013] One side of the diaphragm pump is connected with a pressure regulating gauge.

[0014] The advantages of the present invention compared with the prior art are as follows: The oiling system has three states to flexibly adapt to various application scenarios.

[0015] When the oiling system needs maintenance, the oil in the system pipeline can be discharged into the oil storage barrel by opening the manual ball valve. On the one hand, emptying the oil in the system pipeline is conducive to cleaning and maintenance by workers. On the other hand, the oil can be reused when it flows back to the oil storage barrel to avoid waste.

[0016] When the oiling system is in the initial operation state, the presence of air in the system pipeline is not conducive to uniform spraying of the workpiece surface. By manually turning the three-way valve, the oil in the system pipeline can flow back to the oil storage barrel, and the oil can be used to fill the system pipeline and push the gas out of the system pipeline. The oil subsequently pumped into the system pipeline by the diaphragm pump will not mix with the gas and be sprayed on the workpiece surface, and the spray layer will be more uniform and stable.

[0017] When the oiling system is in normal operation, the three-way valve is manually turned to allow the oil in the system pipeline to flow back to the diaphragm pump through the circulation valve and back pressure valve, thus forming a system internal circulation. The circulation valve and back pressure valve increase the oil pressure, increasing the flow kinetic energy of the oil in the recirculation process, so that the diaphragm pump can pump the oil more easily, making the oiling system run more smoothly.

DETAILED DESCRIPTION

[0020] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0021] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand the advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0022] Embodiment 1 like Figure 1 The oiling system based on the three-axis linkage of CM and PM includes an oil storage barrel 2, a diaphragm pump 3, a filter 4, a first pressure regulating valve 5, a heater 6 and a flow meter 7 which are connected in sequence through a braided tube 1; and also includes a heating block 8 and a water curtain valve 9; the heating block 8 has an oil inlet and an oil return port, one end of the oil inlet of the heating block 8 is connected to the flow meter 7 through a Teflon tube 10, and the other end of the oil inlet of the heating block 8 is connected to the water curtain valve 9 through the Teflon tube 10, so as to guide the oil body into the oil body. After entering the heating block 8 for heating, it is sprayed out by the water curtain valve 9; one end of the oil return port of the heating block 8 is connected to the water curtain valve 9 through a Teflon tube 10, and the other end of the oil return port of the heating block 8 is connected to a three-way valve 13 through a Teflon tube 10, and one end of the three-way valve 13 is connected to the oil storage barrel 2 through the Teflon tube 10; the oil flows back to the heating block 8 from the water curtain valve 9, and flows out from the oil return port of the heating block 8, flows back to the oil storage barrel 2 through the three-way valve 13, and carries the gas in the oiling system into the oil storage barrel 2.

[0023] When the oiling system is in the initial operation state, the presence of air in the system pipeline is not conducive to uniform spraying of the workpiece surface. By manually turning the three-way valve 13, the oil in the system pipeline is returned to the oil storage barrel 2, and the system pipeline is filled with oil and the gas is pushed out of the system pipeline. The oil subsequently drawn into the system pipeline by the diaphragm pump 3 will not be mixed with the gas and sprayed on the workpiece surface, and the spray layer will be more uniform and stable.

[0024] Furthermore, an accumulator 11 is installed on the diaphragm pump 3 ; and a second pressure-stabilizing valve 12 is connected to the oil outlet of the diaphragm pump 3 .

[0025] Furthermore, the three-way valve 13 is connected to the oil inlet of the diaphragm pump 3, and a circulation valve 15 and a back pressure valve 16 are connected between the three-way valve 13 and the diaphragm pump 3 through a Teflon tube 10; after flowing out of the return oil port of the oil heating block 8, it passes through the three-way valve 13, the circulation valve 15 and the back pressure valve 16 in sequence and flows into the diaphragm pump 3 again.

[0026] When the oiling system is in normal operation, the three-way valve 13 is manually turned to allow the oil in the system pipeline to flow back to the diaphragm pump 3 through the circulation valve 15 and the back pressure valve 16, thereby forming a system internal circulation. The circulation valve 15 and the back pressure valve 16 increase the oil pressure, increasing the flow kinetic energy of the oil in the recirculation process, so that the diaphragm pump 3 can pump the oil more easily, making the oiling system run more smoothly.

[0027] Furthermore, the oil inlet and oil return port of the heating block 8 are both provided with a manual ball valve 14; the bottom oil discharge port of the filter 4 is also provided with a manual ball valve 14, and is connected to the oil storage barrel 2 through a braided tube 1; during maintenance, the manual ball valve 14 is opened to discharge the oil into the oil storage barrel 2.

[0028] When the oiling system needs maintenance, the oil in the system pipeline can be discharged into the oil storage barrel 2 by opening the manual ball valve 14. On the one hand, emptying the oil in the system pipeline is conducive to cleaning and workers' maintenance. On the other hand, the oil flows back to the oil storage barrel 2 and can be reused to avoid waste.

[0029] Furthermore, a float level gauge 17 is provided in the oil storage barrel 2 for detecting the liquid level of the liquid inside the oil storage barrel 2 .

[0030] Furthermore, the oiling system is also provided with a controller 18, and the controller 18 controls the operation of the oiling system.

[0031] Furthermore, the three-way valve 13 is a manual three-way valve, and the operation state of the oiling system is switched by manually controlling the closing and opening of two outlets of the three-way valve 13 .

[0032] Furthermore, the inner diameter of the braided tube 1 is 6 mm; the inner diameter of the Teflon tube 10 is 4 mm. The braided tube 1 and the Teflon tube 10 are respectively used to connect various devices in the oiling system, and are set accordingly according to the change of the oil pressure inside the oiling system pipeline. When the oil is pumped from the inside of the oil storage barrel 2 into the inside of the oiling system pipeline by the diaphragm pump 3 until the flow meter 7, the braided tube 1 is used. Because the oil is added with kinetic energy by the diaphragm pump 3, the pressure inside the oiling system pipeline is relatively high. At this time, a braided tube 1 with a stronger structure and a larger inner diameter is required. On the one hand, it can avoid the bursting of the oiling system pipeline, and on the other hand, the larger inner diameter has a certain pressure relief effect. Due to the double pressure reduction through the first pressure regulating valve 5 and the second pressure regulating valve 12, the flow rate of the oil is greatly reduced. At this time, the use of the Teflon tube 10 with a smaller inner diameter is conducive to increasing the flow rate of the oil, so that it can be sprayed out from the water curtain valve 9 more smoothly. When the oiling system is in normal working condition, a larger flow rate and kinetic energy are required for the oil to flow back from the water curtain valve 9 to the diaphragm pump 3. Therefore, the Teflon tube 10 with a smaller inner diameter is used to prevent the oil flow rate from being reduced. On this basis, the oil is more powerful and flows faster after being pressurized by the circulation valve 15 and the back pressure valve 16, and flows back to the diaphragm pump 3 more smoothly.

[0033] Furthermore, a pressure regulator 19 is connected to one side of the diaphragm pump 3 to detect the pressure of the oil in the diaphragm pump 3, thereby controlling the accumulator 11 and the second pressure-stabilizing valve 12 to adjust the pressure of the oil in the oiling system pipeline.

[0034] Working principle: In the initial state, the diaphragm pump 3 extracts the oil in the oil storage barrel 2 and flows back to the oil storage barrel 2 through the accumulator 11, the second pressure regulating valve 12, the filter 4, the first pressure regulating valve 5, the heater 6, the flow meter 7, the heating block 8, the water curtain valve 9 and the three-way valve 13 in sequence. The purpose of the whole process is to remove the air inside the oiling system pipeline. In this state, the three-way valve 13 needs to be manually turned to allow the oil to flow back to the oil storage barrel 2. The manual ball valve 14 on the oil inlet and return port of the heating block 8 is in a normally open state.

[0035] In normal working state, the oiling system starts, the diaphragm pump 3 works, and the oil inside the oil storage barrel 2 is extracted. The oil has kinetic energy when it is pumped into the pipeline of the oiling system. The oil passes through the accumulator 11 and the second pressure regulating valve 12 in turn for pressure regulation, pressure reduction and adjustment, and then is filtered by the filter 4 and flows to the first pressure regulating valve 5. The oil passes through the first pressure regulating valve 5 for pressure regulation and pressure reduction again, and then flows through the heater 6, flow meter 7 and heating block 8. Among them, the heater 6 heats the oil to 40°C, the flow meter 7 monitors the pipeline flow, and the heating block 8 heats the oil to 50°C. Finally, it is sprayed out by the water curtain valve 9 and coated on the workpiece. In this state, the three-way valve 13 needs to be manually turned so that the excess oil passes through the circulation valve 15 and the back pressure valve 16 and is pressurized and then flows back to the diaphragm pump 3 again.

[0036] When in maintenance state, the manual ball valve 14 is in a normally open state, and the oil in the oiling system pipeline flows back from the bottom of the filter 4 to the oil storage barrel 2, thereby draining the oil in the oiling system pipeline.

[0037] Regardless of the state, the float level gauge 17 detects the liquid level inside the oil storage barrel 2 in real time and feeds back the detection signal to the controller 18. When the liquid level inside the oil storage barrel 2 is too low, the controller 18 issues an alarm to remind the operator to add oil to the oil storage barrel 2.
