DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] EMBODIMENT

[0024] Please refer to Figures 1 to 4 The utility model provides technical scheme, a kind of cotton cleaner lubricating device, including oil tank 1, temperature sensor 2 and oil film thickness sensor 3, the top of oil tank 1 is fixedly installed with flow divider 4, one end of flow divider 4 is installed with pressure sensor 5, the other end of flow divider 4 is installed with backflow electric control flow switch 6, the top of the side of oil tank 1 close to flow divider 4 is fixedly installed with micro plunger pump 7, the other side of flow divider 4 is installed with lubricating electric control flow switch 8, the oil outlet of lubricating electric control flow switch 8 is connected with variable diameter plug 9 by screw thread, the outlet of variable diameter plug 9 is connected with collet joint 10 by screw thread, the outlet of collet joint 10 is connected with copper pipe 11.

[0025] Specifically, the oil tank 1 is installed on the outside of the scutcher, and an oil filling port is further arranged on the top of the scutcher to facilitate the addition of lubricating oil. Meanwhile, a cover is arranged on the top of the flow divider 4 to protect the switches and sensors. All the switches and sensors are connected to the electrical control cabinet of the scutcher through cables, so that the lubricating device can be controlled by the control panel of the scutcher to realize automatic monitoring and automatic oiling.

[0026] Please refer to Figure 1 The temperature sensor 2 is a non-contact infrared sensor, and the detection head is close to and opposite to the meshing position of the gear. The temperature sensor is used to detect the temperature of the meshing position of the gear set.

[0027] Specifically, the gear teeth will produce friction during meshing, and the friction will generate heat. The greater the friction, the more heat generated. When the lubricating oil is lacking, the friction will increase, and thus the temperature of the meshing position of the gear set can be detected to determine whether the lubricating oil needs to be added.

[0028] Please refer to Figure 1 The detection head of the oil film thickness sensor 3 is close to and opposite to the gear teeth. The oil film thickness sensor 3 detects the thickness of the oil film on the gear teeth through ultrasonic signals.

[0029] Specifically, a layer of oil film is generated on the surface of the driving gear. The thicker the oil film, the more lubricating oil in the appropriate range. Conversely, when the lubricating oil is lacking, the oil film will be very thin. Thus, the thickness of the gear oil film can be detected to determine whether the oil is lacking.

[0030] Please refer to Figure 4 The detection head of the pressure sensor 5 is fixedly connected to the flow divider 4 through threads and communicates with the internal cavity. The pressure sensor 5 is used to detect the pressure inside the flow divider 4.

[0031] Specifically, a sealed space is provided inside the flow divider 4. When all the electrically controlled flow switches are in the closed state, the internal air will be compressed after the oil is pumped into the cavity by the micro plunger pump 7, and thus the internal pressure will change.

[0032] Please refer to Figures 2 to 4 One end of the return flow electrically controlled flow switch 6 is fixedly connected to the flow divider 4 through threads and communicates with the internal cavity. The other end of the return flow electrically controlled flow switch 6 is connected to the return pipe 12, which is inserted into the oil tank 1.

[0033] Specifically, when the gear set of the scutcher does not need to be lubricated or the pressure inside the flow divider 4 is too high, the return flow electrically controlled flow switch 6 is opened, and the lubricating oil inside the flow divider 4 is returned to the oil tank 1, so that the flow divider 4 does not need to be kept under high pressure for a long time, to avoid damage to the lubricating device due to long-term high pressure.

[0034] Please refer toFigure 3 The oil outlet of the micro-plunger pump 7 is provided with an oil filling pipe 13 between the oil distribution block 4, and the oil inlet of the micro-plunger pump 7 is connected with an oil suction pipe 14 inserted into the oil tank 1, and the micro-plunger pump 7 pumps the lubricating oil in the oil tank 1 into the oil distribution block 4 when working.

[0035] Specifically, the micro-plunger pump 7 changes the sealed volume by reciprocating movement of the plunger in the cylinder, and can suck the oil in the oil tank 1 through the oil suction pipe 14 and fill it into the oil distribution block 4 through the oil filling pipe 13, wherein the oil filling pipe 13 is an explosion-proof oil pipe that needs to withstand high internal pressure. Since the micro-plunger pump 7 is small in size, the internal oil cylinder is also small, and thus the oil cylinder can only fill a small amount of lubricating oil into the oil distribution block 4 every cycle, and the oil pressure inside the oil distribution block 4 can also be accurately controlled within the set range. Since the consumption of lubricating oil is very slow, even the micro-plunger pump 7 can meet the oiling demand.

[0036] Please refer to Figure 1 and 3 One end of the lubricating electric control flow switch 8 is fixedly connected with the oil distribution block 4 through threads and communicates with the internal cavity, and the lubricating oil in the oil distribution block 4 is discharged from the thin copper pipe 11 under the action of pressure and falls on the gear when the lubricating electric control flow switch 8 is opened.

[0037] Specifically, the cleaner has as many lubricating electric control flow switches 8 as gear sets, and each lubricating electric control flow switch 8 is connected with a thin copper pipe 11 with an inner diameter of only about three millimeters, which can withstand high pressure and is easy to bend, thereby facilitating installation. The end of the thin copper pipe 11 is arranged above the meshing position of the gear, so that the lubricating oil can fall on the gear by relying on its own gravity.

[0038] When in use, the oil film thickness sensor 3 and the temperature sensor 2 need to automatically detect the temperature and the thickness of the oil film at the meshing position of the gear set every five minutes after the cleaning machine is started and every two hours, wherein the temperature range and the thickness range of the oil film required by the detection before five minutes and after every two hours are different, and the qualified range of the temperature detection is also different under different environments, such as the temperature of the working environment is 20℃, the temperature required by the detection before five minutes is 20-25℃, and the temperature range required by the detection after every two hours is 35-55℃, the thickness of the oil film is also different under different rotating speeds, the faster the rotating speed is, the smaller the thickness of the oil film is, the thickness of the oil film of different types of lubricating oil is also different, the thicker the lubricating oil is, the larger the thickness of the oil film is, and the amount and the way of the oil adding are also different, when the temperature is too high or the thickness of the oil film is too low before five minutes, the oil is added quantitatively, and then the detection is performed every half an hour, the oil is added through the feedback of the temperature sensor 2 and the oil film thickness sensor 3 after every two hours, that is, the oil is added until the thickness of the oil film is in the set range or the temperature decreases, as for the qualified range of the temperature and the qualified range of the oil film, they cannot be calculated, and the data are obtained through practice under the normal working condition, and then the control range is programmed according to the data obtained through practice, that is, the oil is added as long as the temperature and the thickness of the oil film deviate from the data obtained through practice, all the gear sets can be added at the same time, they will not affect each other, as long as the pressure in the internal part of the flow dividing block 4 is in the set range, there will be no problem, if the oil is added at one point even if the other points are opened during the process, but the thickness of the oil film does not change, then the other points are closed and the oil is added at the point, if the lubricating electric control flow switch 8 is opened but the pressure in the internal part of the flow dividing block 4 does not change, then the thin copper pipe 11 and the block corresponding to the point are blocked, if the pressure in the internal part of the flow dividing block 4 decreases but the thickness of the oil film does not thicken, then the thin copper pipe 11 corresponding to the point leaks oil.

[0039] In summary, the lubricating device of the cleaning machine is provided with a thin copper pipe 11 for each gear set, each thin copper pipe 11 is controlled by a separate lubricating electric control flow switch 8, and each gear set can be lubricated separately, and the pressure sensor 5 can monitor the pressure inside the flow divider 4 in real time, under normal circumstances, when the lubricating electric control flow switch 8 is opened, lubricating oil will flow out and the oil film thickness at the lubricating position will increase, if the lubricating electric control flow switch 8 is opened but the pressure inside the flow divider 4 does not change, it indicates that the oil pipe is blocked, if the lubricating electric control flow switch 8 is opened and the pressure inside the flow divider 4 decreases but the oil film thickness does not increase, it indicates that the oil pipe is broken, the oil pressure inside the flow divider 4 can be controlled within a specified range through the monitoring of the pressure sensor 5, the amount of lubricating oil squeezed out from the pipe by pressure per unit time can be accurately controlled when the switch is opened under the condition that the oil pressure is accurate, since the inner diameter of the thin copper pipe 11 is small, the amount of lubricating oil discharged per unit time is also small, and thus the amount of lubricating oil added is not large even if the pressure and time control are not very accurate when lubricating, therefore, the amount of lubricating oil can be accurately controlled.

[0040] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
