Description

Technical Field

[0001] The utility model relates to the technical field of thin oil devices, in particular to a thin oil device for a feeder. Background Technique

[0002] A feeder is used to continuously and evenly transport materials into a target device, ensuring the smooth operation of a production line and avoiding material blockage or interruption. Therefore, during the operation of the feeder, its internal mechanical components (such as bearings, gears, etc.) need to undergo long-term friction. For this reason, an oil thinning station is usually set up to provide continuous lubricating oil supply to its mechanical components. By forming an oil film on the friction parts, direct contact and wear are reduced, and the service life of the equipment is extended.

[0003] Due to the continuous friction of mechanical components such as bearings and gears during long-term operation, a large amount of heat will also be generated. If this heat cannot be effectively dissipated, not only will these mechanical components be damaged due to overheating, but the effect of the lubricating oil will also be reduced, thereby affecting the performance and service life of the feeder. To ensure the stable operation of the feeder, the oil thinning station continuously circulates the lubricating oil and cools it, so that the circulating lubricating oil not only plays a role in heat dissipation, but also takes away heat and cools the mechanical components. However, the existing thin oil devices for feeders usually continuously cool the lubricating oil, that is, continuously cool the lubricating oil returned from the feeder. Although this method can ensure the cooling effect of the lubricating oil, it will cause unnecessary energy consumption when the feeder is running lightly, and may cause poor cooling effect when the feeder is running heavily.

Specific embodiments

[0017] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0018] A thin oil device for a feeder in this embodiment, referring to the attached Figure 1 , includes a circulating oil tank 1, an oil supply pump 2, a cooler 3 and a temperature detection component. The oil supply end of the circulating oil tank 1 is connected to the oil inlet end of the oil supply pump 2. The oil discharge end of the oil supply pump 2 is connected to one end of the cooler 3. The other end of the cooler 3 is connected to the oil supply end of the feeder through the oil supply pipeline 11. The oil return end of the feeder is connected to the oil return end of the cooling oil tank through the oil return pipeline 12. The temperature detection component is used to detect the oil temperature of the lubricating oil in the oil supply pipeline 11 and the oil return pipeline 12. When the temperature detection component detects that the oil temperature of the lubricating oil in the oil return pipeline 12 is higher than the set value, the cooler 3 starts to work. When the temperature detection component detects that the oil temperature of the lubricating oil in the oil supply pipeline 11 is lower than the set value, the cooler 3 stops working.

[0019] By setting the circulating oil tank 1, the oil supply pump 2 and the cooler 3, the circulation of the lubricating oil between the circulating oil tank 1 and the feeder is realized by the action of the oil supply pump 2, ensuring continuous lubrication of the feeder during operation. And by setting the temperature detection component to monitor the oil temperature of the lubricating oil in the oil supply pipeline 11 and the oil return pipeline 12 in real time, and adjusting the working state of the cooler 3 in time according to the detection result of the temperature detection component, it is ensured that the lubricating oil can be maintained within a suitable temperature range during operation, avoiding equipment wear and performance degradation caused by too high oil temperature, and also saving energy waste caused by continuous operation of the cooler 3.

[0020] Preferably, the temperature detection component includes a temperature controller, a supply oil temperature probe 41 and a return oil temperature probe 42. The supply oil temperature probe 41 is arranged in the supply oil pipeline 11, and the return oil temperature probe 42 is arranged in the return oil pipeline 12. Both the supply oil temperature probe 41 and the return oil temperature probe 42 are electrically connected to the input end of the temperature controller, and the output end of the temperature controller is electrically connected to the control end of the cooler 3. The temperature controller is electrically connected to the supply oil temperature probe 41 and the return oil temperature probe 42 for receiving the detected values of the supply oil temperature probe 41 and the return oil temperature probe 42. Thus, the temperature for starting refrigeration and the temperature for stopping refrigeration can be set. During the automatic operation of the device, when the oil temperature of the lubricating oil in the supply oil pipeline 11 exceeds the set temperature value for starting refrigeration or the oil temperature of the lubricating oil in the return oil pipeline 12 is lower than the set temperature value for stopping refrigeration, the start and stop of the cooler 3 can be automatically controlled by the temperature controller to keep the supply oil temperature within the set range. In this embodiment, the set temperature value for starting refrigeration is 70 °C, that is, when the oil temperature of the lubricating oil in the supply oil pipeline 11 exceeds 70 °C, the cooler 3 starts refrigerating, and the set temperature value for stopping refrigeration is 60 °C, that is, when the oil temperature of the lubricating oil in the return oil pipeline 12 is lower than 60 °C, the refrigeration of the cooler 3 stops. The setting of the return oil temperature probe 42 can also detect whether the feeder is working abnormally. When the return oil temperature probe 42 detects that the temperature of the lubricating oil in the return oil pipeline 12 exceeds 110 °C, it indicates that the feeder may be working abnormally. At this time, the feeder is stopped and waiting for maintenance personnel to repair.

[0021] Furthermore, the temperature detection component further includes a tank temperature probe. The tank temperature probe is arranged in the circulating tank 1. A heater is arranged in the circulating tank 1. The temperature detection probe is electrically connected to the input end of the temperature controller, and the output end of the temperature controller is electrically connected to the control end of the heater. When the tank temperature detection probe detects that the temperature of the lubricating oil in the tank is lower than 20 °C, the heater starts to work until the temperature of the lubricating oil in the tank exceeds 30 °C, and then the heater stops working, thereby ensuring that the lubricating oil is kept within the optimal working temperature.

[0022] Preferably, it further includes a supply oil filter 51 and a return oil filter 52. One end of the supply oil filter 51 is connected to the oil discharge end of the oil supply pump 2, and the other end of the supply oil filter 51 is connected to one end of the cooler 3; one end of the return oil filter 52 is connected to the return oil passage, and the other end of the return oil filter 52 is connected to the return oil end of the circulating tank 1. By setting the supply oil filter 51 and the return oil filter 52, the lubricating oil needs to pass through the filter during both the supply and return processes, ensuring that the oil cleanliness meets the standard requirements, thereby reducing the wear of mechanical components caused by impurities mixed in the lubricating oil and maintaining the stability and performance of the feeder.

[0023] Preferably, one end of the one-way valve 6 is connected to the other end of the oil supply filter 51, and the other end of the one-way valve 6 is connected to one end of the cooler 3. By setting the one-way valve 6, it is ensured that the lubricating oil will not flow back from the cooler 3 to the oil supply filter 51, which protects the filter and prevents the backflow from causing additional pressure or damage to the filter. The setting of the one-way valve 6 can also maintain a stable oil flow direction and flow rate, and improve the working efficiency of the oil thinning device.

[0024] Preferably, the device further comprises an overflow valve 7 and a flow control valve 8, one end of the overflow valve 7 is connected to the oil supply pipeline 11, the other end of the overflow valve 7 is connected to the circulating oil tank 1, one end of the flow control valve 8 is connected to the oil supply pipeline 11, and the other end of the flow control valve 8 is connected to the circulating oil tank 1. By arranging the overflow valve 7 in the overflow pipeline between the oil supply pipeline 11 and the circulating oil tank 1, when the oil pressure in the oil supply pipeline 11 exceeds the preset safety threshold, the overflow valve 7 automatically opens to guide the overflow part of the lubricating oil back to the circulating oil tank 1, thereby preventing damage to the thin oil device caused by excessive oil pressure, and improving the safety and stability of the operation of the thin oil device. By arranging the flow control valve 8 in the flow control pipeline between the oil supply pipeline 11 and the circulating oil tank 1, the flow control valve 8 is used to control the flow of the lubricating oil in the oil supply pipeline 11, and the flow control valve 8 is arranged to return the lubricating oil in the oil supply pipeline 11 to the circulating oil tank 1, which is also convenient for maintenance operations.

[0025] Preferably, an oil level gauge 13 and a liquid level sensor 14 are also included. Both the oil level gauge 13 and the liquid level sensor 14 are arranged in the circulating oil tank 1. The circulating oil tank 1 is provided with an oil filling port 15 and an oil drain valve 16. By arranging the oil level gauge 13 in the circulating oil tank 1, it is convenient for operators to obtain the oil level in the circulating oil tank 1. By arranging the liquid level sensor 14, when the liquid level in the circulating oil tank 1 is lower than the set value, the liquid level sensor 14 sends out an alarm, stops the oil thinning device from working, and ensures the stable operation of the device.

These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
