Description

Technical Field

[0001] This utility model applies to the field of lubricating oil repackaging technology, and in particular relates to a high-efficiency lubricating oil repackaging mechanical device. Background Technology

[0002] Currently, lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. After the lubricating oil is produced, it needs to be packaged into multiple tanks for convenient storage and sales.

[0003] However, current lubricating oil repackaging processes require the use of dispensing nozzles to inject the lubricating oil stored in the storage tank into separate storage tanks. During this process, the high viscosity of the lubricating oil results in poor flowability within the tanks. Consequently, the lubricating oil cannot be quickly discharged, and a large amount adheres to the inner wall of the tank, hindering proper drainage. This results in sufficient dispensing volume but reduced dispensing efficiency. Therefore, we propose a high-efficiency lubricating oil dispensing machine. Utility Model Content

[0004] The main objective of this invention is to provide a high-efficiency lubricating oil dispensing machine that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-efficiency lubricating oil dispensing machine includes a storage tank, the top of which is detachably fitted with a sealing cover plate by bolts, and a hollow frame is fixedly installed at the bottom center of the sealing cover plate.

[0007] A lifting plate is movably provided at the bottom of the sealing cover, and a pressing plate is movably provided at the bottom of the lifting plate. The diameter of the lifting plate and the pressing plate is the same as the inner diameter of the storage tank. A driving mechanism is provided inside the hollow frame, and the driving mechanism is connected to the lifting plate in a transmission manner.

[0008] The top of the lifting plate is vertically fixed with a hollow tube, and there are four sets of hollow tubes. Each hollow tube is equipped with a pushing mechanism, and the pushing mechanism is connected to the top surface of the extrusion plate.

[0009] As an optional solution to the technical solution of this application, the driving mechanism includes a bidirectional lead screw. The bidirectional lead screw is installed laterally inside the hollow frame via bearings. Both sides of the bidirectional lead screw are connected to transmission sleeves via threads. A connecting block is fixedly installed at the bottom of the outer side of each transmission sleeve. Sliding plates are slidably installed on both sides of the bottom of the hollow frame, and the bottom of the connecting block and the top of the sliding plate are fixedly connected. A push plate is inclinedly hinged to the bottom of the sliding plate via a rotating shaft, and the bottom of the push plate is hinged to the top surface of the lifting plate via a rotating shaft. A servo motor is fixedly installed on the side of the hollow frame, and the side of the servo motor drive shaft is connected to the top of the side of the bidirectional lead screw via a coupling.

[0010] By adopting the above technical solution, the rotational transmission of the transmission sleeve by the bidirectional screw and the transmission conversion action of the push plate can provide active moving force to the lifting plate and the extrusion plate. The vertical position of the lifting plate and the extrusion plate inside the storage tank can be adjusted, so that the extrusion plate can push and detach the raw materials adhering to the inner wall of the tank from the top of the lubricating oil stored inside the tank. This avoids the adhesion of lubricating oil, which affects its dispensing and usage. At the same time, the extrusion plate can squeeze the lubricating oil to accelerate its discharge and dispensing rate.

[0011] As an optional solution to the technical solution of this application, the pushing mechanism includes a pushing spring, a movable plate is slidably installed inside each hollow tube, a pushing spring is movably installed inside each hollow tube, and a movable rod is vertically fixedly installed at the bottom center of the movable plate. The movable rod slides through the inside of the lifting plate, and the bottom of the movable rod is fixedly connected to the top of the extrusion plate.

[0012] By adopting the above technical solution, the moving plate and the squeezing plate are provided with corresponding vertical pushing force through the structure of the pushing spring. As the amount of lubricating oil decreases, the squeezing plate can continue to move downward and automatically scrape off the lubricating oil material adhering to the inner wall of the storage tank, further avoiding the use of lubricating oil in the repackaging process.

[0013] As an optional solution to the technical solution of this application, the bottom of the storage tube is fixedly connected to a connecting pipe, the bottom of the connecting pipe is fixedly installed with a metering valve, the bottom of the discharge port of the metering valve is fixedly connected to a discharge pipe, and the bottom of the discharge pipe is fixedly connected to an injection nozzle.

[0014] By adopting the above technical solution, the quantitative dispensing and discharge of lubricating oil can be achieved through the structural function of the metering valve.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present application discloses a high-efficiency lubricating oil dispensing machine, which, by setting a sealing cover plate on the top of the storage tank and a hollow frame inside the sealing cover plate, and by combining the rotation of the bidirectional screw inside the hollow frame with the rotation of the transmission sleeve, allows two sets of transmission sleeves to move horizontally in opposite directions within the hollow frame. Subsequently, under the connecting transmission action of the connecting block, the sliding plate can be driven to move horizontally in opposite directions on the bottom surface of the hollow frame. After connecting the two ends of the push plate with the sliding plate and the lifting plate respectively by the rotating shaft, the horizontal movement force of the transmission sleeve can be converted into a vertical pushing force on the lifting plate. This allows the vertical position of the lifting plate and the extrusion plate inside the storage tank to be adjusted, so that the extrusion plate can push and detach the raw material adhering to the inner wall of the tank from the top of the lubricating oil stored inside the tank, avoiding the adhesion of lubricating oil and affecting its dispensing and usage. At the same time, the extrusion plate can squeeze the lubricating oil to accelerate its discharge and dispensing rate.

[0017] 2. The present application provides a high-efficiency lubricating oil dispensing machine, which includes multiple sets of hollow tubes on the top of a lifting plate and push springs inside the hollow tubes. The push springs, in conjunction with the vertical pushing action of the moving plate, cause the lifting plate to move vertically in sync with the extrusion plate, so that the bottom surface of the extrusion plate is in contact with the top surface of the lubricating oil. The push springs then provide corresponding vertical pushing force to the moving plate and the extrusion plate. As the amount of lubricating oil decreases, the extrusion plate can continuously move downwards, automatically scraping and removing the lubricating oil material adhering to the inner wall of the storage tank, further reducing the amount of lubricating oil used during dispensing.

[0022] like Figure 1-3 As shown, this utility model provides a technical solution: a high-efficiency lubricating oil dispensing machine. A sealing cover plate 15 is detachably installed on the top of the storage tank 1 by bolts. A hollow frame 22 is fixedly installed at the bottom middle of the sealing cover plate 15. A connecting pipe 11 is fixedly connected to the bottom of the storage pipe. A metering valve 12 is fixedly installed at the bottom of the connecting pipe 11. The metering valve 12 is a diaphragm-type volume control valve, specifically a DV-Y series valve. It uses the deformation of an elastic diaphragm to change the flow cross-sectional area to achieve fixed volume metering. The corrugated diaphragm separates the upper and lower chambers. The lower chamber is connected to the connecting pipe 11, and the upper chamber is open to the atmosphere or a low-pressure area. In the initial state, the diaphragm is tightly sealed against the valve seat. When the lubricating oil flows into the lower chamber, the diaphragm bulges up, exposing the metering orifice. When the pressure reaches equilibrium, it automatically closes, thereby realizing the metering and dispensing of lubricating oil. A discharge pipe 13 is fixedly connected to the bottom of the discharge port of the metering valve 12. An injection nozzle 14 is fixedly connected to the bottom of the discharge pipe 13.

[0023] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a hollow tube 3 is vertically fixedly installed on the top of the lifting plate 2, and there are four sets of hollow tubes 3. The lifting plate 2 is movably installed at the bottom of the sealing cover plate 15, and a pressing plate 21 is movably installed at the bottom of the lifting plate 2. The diameter of the lifting plate 2 and the pressing plate 21 is the same as the inner diameter of the storage tank 1. A movable plate 31 is slidably installed inside each hollow tube 3. A push spring 33 is movably installed inside each hollow tube 3, and the two ends of the push spring 33 are respectively movably attached to the outer side of the movable plate 31 and the inner side wall of the hollow tube 3. A movable rod 32 is vertically fixedly installed at the middle of the bottom of the movable plate 31. The movable rod 32 slides through the inside of the lifting plate 2, and the bottom of the movable rod 32 is fixedly connected to the top of the pressing plate 21.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, a bidirectional lead screw 23 is installed inside the hollow frame 22 via a bearing for lateral rotation. Both sides of the bidirectional lead screw 23 are threadedly connected to transmission sleeves 24. The two sides of the bidirectional lead screw 23 have threads with opposite helical directions. The inner wall of the transmission sleeve 24 has a matching thread. A connecting block 25 is fixedly installed at the bottom of each transmission sleeve 24. A corresponding groove is provided at the bottom of the hollow frame 22, and the connecting block 25 is slidably inserted into the groove. Combined with the abutment action of the groove on the connecting block 25, the transmission sleeve 24 will not rotate axially with the rotation of the bidirectional lead screw 23, allowing it to move horizontally only inside the hollow frame 22. Sliding plates 26 are slidably installed on both sides of the bottom of the hollow frame 22, and the bottom of the connecting block 25 and the top of the sliding plate 26 are fixedly connected.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the sliding plate 26 is inclinedly hinged to the push plate 27 via a rotating shaft, and the bottom of the push plate 27 is hinged to the top surface of the lifting plate 2 via a rotating shaft. The side of the hollow frame 22 is fixedly installed with a servo motor 28, and the side of the transmission shaft of the servo motor 28 is connected to the top of the side of the double-acting screw 23 via a coupling.

[0026] During operation, after the lubricating oil for dispensing is injected into the storage tank 1 to reach the predetermined storage height, a conveyor belt is used to place the multi-component dispensing tanks at the bottom of the injection nozzle 14. Simultaneously, the metering valve 12 is activated to meteredly deliver the lubricating oil from the storage tank 1 into the dispensing tanks. As the lubricating oil level in the storage tank 1 continuously decreases, the resistance force exerted by the top of the lubricating oil on the bottom surface of the extrusion plate 21 disappears. Combined with the pushing action of the push spring 33 on the movable plate 31, the movable plate 31 can move vertically within the hollow tube 3. Under the connecting transmission action of the movable rod 32, the extrusion plate 21 can be driven to continuously decrease with the lubricating oil level. The bottom surface of the extrusion plate 21 can continuously move downwards, pushing the lubricating oil adhering to the inner wall of the storage tank 1 downwards. The lubricating oil is dispensed and used separately. After the extrusion plate 21 moves vertically to the corresponding position and can no longer move downward, the servo motor 28 is started, which drives the bidirectional lead screw 23 to rotate. Combined with the rotational transmission action of the bidirectional lead screw 23 on the transmission sleeve 24 and the connecting transmission action of the connecting block 25, the sliding plate 26 can be driven to move horizontally towards each other on the bottom surface of the hollow frame 22 along with the horizontal movement of the transmission sleeve 24. Then, under the transmission conversion action of the push plate 27, the lifting plate 2 and the extrusion plate 21 can be driven to move vertically synchronously. The vertical position of the extrusion plate 21 is adjusted to ensure that its bottom surface is always in contact with the top surface of the lubricating oil, continuously extruding the lubricating oil to accelerate its discharge rate, while removing the lubricating oil adhering to the inner wall of the storage tank 1.
