Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for cigarette making workshops, and in particular to an oil receiving device for a cigarette making reducer. Background Technology

[0002] In large cigarette factories, there are numerous transmission devices in the tobacco processing workshop, among which a large number of speed reducers are used. According to the equipment maintenance system, the lubricating oil of the speed reducers that have reached their replacement cycle needs to be replaced gradually.

[0003] The traditional replacement method usually involves simultaneously unscrewing the drain screw and oil drain screw of the reducer, allowing the waste oil in the reducer to flow out from the lowest oil drain screw under gravity. The discharged waste oil is collected manually in an oil collection box and poured into a waste oil collection bucket. After the waste oil is drained, new lubricating oil is added to flush the reducer, the oil drain screw is tightened again, and then new lubricating oil is added. The waste oil or new oil flows out by its own gravity, which takes a long time.

[0004] To overcome the above difficulties, the existing technology provides a solution that uses an air pump (or other negative pressure source) to create a negative pressure state in the waste oil collection tank and then connects it to the reducer, thereby facilitating the efficiency of changing the reducer lubricating oil under negative pressure. However, the above solution has the following problems: when changing to new oil, it is not possible to quickly determine whether the flowing oil is pure lubricating oil. By the time the operator realizes this, a large amount of new lubricating oil has entered the waste oil collection tank through the recovery pipeline, resulting in waste. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an oil receiving device for a yarn making reducer, so as to solve the problem of waste caused by changing the lubricating oil in the existing yarn making reducer.

[0006] This utility model solves the above-mentioned technical problems through the following technical means: an oil receiving device for a yarn making reducer, including an oil receiving pipeline connected to a negative pressure source, one end of the oil receiving pipeline being provided with a connector detachably connected to the oil drain port of the reducer, the negative pressure source causing the reducer oil to flow out faster; a transparent detection cavity is provided on the oil receiving pipeline, a light source is provided on one side of the transparent detection cavity, and a transparency sensor for detecting the transparency of the lubricating oil is provided on the transparent detection cavity opposite the light source;

[0007] The transparent detection cavity is equipped with an electromagnetic three-way valve at its outlet. One outlet of the electromagnetic three-way valve is connected to a waste oil recovery tank, and the other outlet is connected to a collection tank.

[0008] Optionally, the transparent detection chamber is located at one end of the oil inlet pipe near the connector. This reduces the risk of contamination of the clean lubricating oil entering the collection tank.

[0009] Optionally, the transparent detection cavity is rectangular.

[0010] Optionally, the light source is a white LED.

[0011] Optionally, the light from the light source passes perpendicularly through the transparent detection cavity and illuminates the transparency sensor. The light source and the transparency sensor are positioned on opposite sides of the cuboid, ensuring that the light from the light source illuminates the transparency sensor perpendicularly, thus reducing the intensity loss of the light source.

[0012] Optionally, both the waste oil recovery tank and the collection tank are equipped with air pumps at their tops. These air pumps draw air from the waste oil recovery tank and the collection tank to create a negative pressure source. When the oil inlet pipe connected to the negative pressure source is connected to the reducer's oil drain port, the efficiency is very high for draining, flushing, or adding oil.

[0013] Optionally, the connector is a threaded union. The external thread of the threaded union allows for quick connection between the oil inlet pipe and the oil drain port of the reducer.

[0014] The beneficial effects of this utility model are:

[0015] This invention reduces waste during batch replacement of gearbox lubricating oil by installing a transparent detection cavity on the oil inlet pipeline and using a light source and transparency sensor to monitor the lubricating oil during the oil change process. It also controls an electromagnetic tee to switch the pipeline to different recycling and collection buckets to collect waste oil, flushing oil and clean lubricating oil respectively.

In the description of this utility model, it should be understood that if terms such as "upper", "lower", "left", "right", "front", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figure, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.

[0021] like Figures 1-2 As shown, this utility model provides an oil receiving device for a wire-making reducer, comprising: an oil receiving pipeline 1 connected to a negative pressure source, one end of the oil receiving pipeline 1 being provided with a connector 11 detachably connected to the oil drain port of the reducer, the connector 11 being a threaded union 11, opening the drain screw or drain valve of the reducer, the negative pressure source causing the reducer oil to flow out at an accelerated rate.

[0022] This embodiment also includes a control system for controlling the start and stop of the negative pressure source. The control system can be a well-established microcontroller or programmable logic controller (PLC). Receiving sensor signals and processing them through the above system, as well as controlling the start and stop of various solenoid valves and pumps, are all existing technologies and will not be described in detail here.

[0023] In this embodiment, a transparent detection chamber 13 is provided on the oil inlet pipeline 1. The transparent detection chamber 13 is rectangular in shape. A light source 131 is provided on one side of the transparent detection chamber 13, and a transparency sensor 132 is provided on the transparent detection chamber 13 opposite to the light source 131. The transparency sensor 132 is electrically connected to the control system. The control system acquires the critical light signal of the oil transparency collected by the transparency sensor 132, and controls the negative pressure source to stop or decelerate according to the critical light signal.

[0024] The main principle of the transparency sensor 132 is to characterize the transparency of the oil by measuring the intensity of transmitted light after light passes through the oil, thereby determining whether the lubricating oil is clean. It is more commonly used in water quality testing, but in this embodiment, the transparency of the lubricating oil can be obtained through commercial channels.

[0025] It should be understood that, due to the differences in transparency among different types of lubricating oil, the device should be calibrated using a standard sample of this batch of lubricating oil before use to ensure the accuracy of the transparency sensor 132 and to calibrate the appropriate critical light signal.

[0026] In this embodiment, the transparent detection chamber 13 is located at one end of the oil inlet pipe 1 near the connector 11, reducing the risk of contamination of the clean lubricating oil entering the collection tank 16.

[0027] In this embodiment, an electromagnetic three-way valve 14 is provided at the outlet end of the transparent detection chamber 13. One outlet of the electromagnetic three-way valve 14 is connected to the waste oil recovery tank 12, and the other outlet is connected to the collection tank 16. The electromagnetic three-way valve 14 is electrically connected to the control system, and the control system controls the electromagnetic three-way valve 14 to switch outlets according to the critical light signal of the oil transparency. Both the waste oil recovery tank 12 and the collection tank 16 are equipped with air pumps 15 at their tops. The air pumps 15 draw air from the waste oil recovery tank 12 and the collection tank 16 to form a negative pressure source.

[0028] In this embodiment, the other end of the oil inlet pipe 1 is connected to a waste oil recovery tank 12. A vacuum pump 15 is installed on the top of the waste oil recovery tank 12. The waste oil recovery tank 12 uses the vacuum pump 15 to draw air to form a negative pressure source. It is understood that the vacuum pump 15 can also be replaced with other devices capable of creating a stable vacuum within the sealed container, such as various vacuum pumps or vacuum generators based on Bernoulli's principle.

[0029] It should be understood that the oil receiving device in this embodiment can be installed on the trolley structure, which facilitates the oil receiving operation by moving it within the workshop.

[0030] The working principle of this utility model is as follows:

[0031] When using the oil receiving device of this utility model to collect oil, the corresponding reducer should be in a stopped state. Unscrew the oil drain screw of the reducer's oil drain port, and quickly connect the connector 11 to the oil drain port so that the outlet of the electromagnetic three-way valve 14 is connected to the waste oil collection tank 12. Then loosen or remove the venting screw of the reducer, turn on the vacuum pump 15 on the waste oil collection tank 12, so that a negative pressure is formed in the waste oil collection tank 12, and the waste oil quickly enters the waste oil collection tank 12 from the oil receiving pipe 1 to achieve collection.

[0032] After the waste oil is collected, new lubricating oil is added to the reducer through the drain screw or other oil inlet for flushing. Similarly, the flushing oil after flushing the reducer quickly enters the waste oil recovery tank 12 from the oil inlet pipe 1 for collection.

[0033] When the control system acquires the critical light signal of the oil transparency collected by the transparency sensor 132, indicating that the impurity content in the flushing oil is very low, the control system shuts off the vacuum pump 15 on the waste oil recovery tank 12, switches the outlet of the solenoid three-way valve 14 to the collection tank 16, turns on the vacuum pump 15 on the collection tank 16 to collect the relatively clean flushing oil, and continuously adds new lubricating oil to the standard level. After stopping the addition, tighten the drain screw, turn off the vacuum pump 15 on the collection tank 16, and remove the connector 11 at the oil drain port. The residual lubricating oil in the oil inlet pipe 1 flows rapidly into the collection tank 16 under the action of atmospheric pressure, its own weight, and the residual negative pressure in the collection tank 16, and will not flow out and cause workshop pollution. The clean flushing oil and new lubricating oil collected in the collection tank 16 can be used again for flushing or adding.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
