Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, specifically an automatic oiling mechanism. Background Technology

[0002] Chain conveyors are widely used conveying equipment in material handling and automated production lines. They utilize chains as traction components, and the continuous movement of the chains propels materials or workpieces along a designated path. A typical chain conveyor consists of a drive unit, chain, sprockets, conveyor troughs (or pallets), tensioning devices, and guiding devices. The drive unit provides power, causing the chain and sprockets to rotate and drive the entire conveyor belt. Because the movement of the conveyor belt is primarily achieved through the transmission action of the chain and sprockets, the friction between them is significant.

[0003] To prevent premature wear of chains and sprockets, lubricating oil is typically applied to conveyor belts during use to reduce friction and extend their lifespan. Common methods for adding lubricating oil include manual lubrication, which involves disassembling the parts requiring lubrication and manually adding oil or grease. For large conveyor belts, a lubrication machine is used manually to apply grease to designated areas. For conveyor belts operating under high loads for extended periods, frequent lubrication is necessary. Therefore, the aforementioned lubrication methods are labor-intensive, and the amount of oil applied is difficult to control, heavily influenced by operator subjectivity. To address these issues, an automatic lubrication mechanism is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automatic oiling mechanism. The conveyor belt has an oiling part outside the drive transmission mechanism. The needle valve oil cup in the oiling part can automatically drip lubricating oil into the transmission part of the drive transmission mechanism, thereby replacing the manual oiling method. This can significantly reduce the labor cost. At the same time, the dripping volume and dripping rate of the needle valve oil cup can be adjusted, thus avoiding the errors and omissions that exist in manual oiling. It can also ensure that the transmission part of the drive transmission mechanism is always in an oil-immersed state, improving the efficiency of lubricating oil use. This solves the technical problems of the prior art where manual lubricating oiling consumes a lot of manpower and the oiling volume is not easy to control, and is greatly affected by the operator's subjectivity.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] An automatic oiling mechanism includes a material selection conveyor belt with a drive transmission mechanism installed at its end. The drive transmission mechanism drives the material selection conveyor belt to work, and a collection cover is installed on the material selection conveyor belt. An oiling part is installed on the outside of the drive transmission mechanism to drip lubricating oil onto the transmission part of the drive transmission mechanism. The oiling part of the conveyor belt can automatically drip lubricating oil onto the transmission part of the drive transmission mechanism, thereby replacing the manual oiling method, which can significantly reduce the labor cost. At the same time, the automatic mechanical oiling method can also avoid the errors and omissions that exist in manual oiling.

[0007] In one possible implementation, the oiling unit includes an isolation cover with a threaded hole at its top, through which a needle valve-type oil cup is threadedly connected. The oil outlet of the needle valve-type oil cup is vertically downward, and an oil recovery tank is provided at the bottom of the isolation cover, through which an oil recovery pipe is connected. The needle valve-type oil cup can automatically drip lubricating oil into the transmission part of the drive transmission mechanism, thereby replacing manual filling and significantly reducing labor costs. At the same time, the dripping volume and dripping rate of the needle valve-type oil cup can be adjusted, thus avoiding errors and omissions that occur with manual oil filling. It can also ensure that the transmission part of the drive transmission mechanism is always in an oil-immersed state, improving the efficiency of lubricating oil use. The lubricating oil dripping under the action of gravity will be discharged from the oil recovery tank and can be recycled to reduce costs.

[0008] In one possible implementation, the material selection conveyor belt includes a side frame in which the belt body is installed, and a drive roller for driving the belt body to move is installed at the end of the side frame. The above structure constitutes the most basic structure of the material selection conveyor belt. When the drive roller is driven to rotate by an external force, it can drive the belt body to move and complete the conveying of materials.

[0009] In one possible implementation, the drive transmission mechanism includes a mounting plate on a side frame, on which a drive motor is mounted. The output shaft of the drive motor is fixedly connected to a drive sprocket, and the end of the drive roller is fixedly connected to a driven sprocket. The drive sprocket and the driven sprocket are connected by a chain drive. In the above structure, the drive sprocket, the driven sprocket, and the chain constitute the transmission structure of the drive transmission mechanism, which transmits the torque output by the drive motor to the drive roller, causing it to rotate.

[0010] In one possible implementation, the driving sprocket, driven sprocket, and chain are all located inside an isolation cover, with the needle valve oil cup positioned directly above them and its outlet aligned with the chain. This structure ensures that the drive transmission mechanism is within the protection zone of the isolation cover, preventing foreign objects from entering and causing increased wear. Simultaneously, the needle valve oil cup's placement ensures that falling lubricating oil can directly wet the chain, improving lubricating oil efficiency.

[0011] In one possible implementation, the collection hood includes a housing with a collection port at the bottom facing downwards. A front baffle facing the collection port is installed inside the housing, and a side baffle is installed on the side of the housing near the drive transmission mechanism. When the air-blowing screening device blows up materials that meet the standards, they will enter the housing through the collection port and fall onto the material selection conveyor belt under gravity and be transported away. The front baffle and side baffle can play a role in shielding and isolating, restricting the flying materials to fall onto the material selection conveyor belt in the designated area, so that they can be transported away smoothly.

[0012] In summary, this utility model has the following beneficial technical effects:

[0013] The conveyor belt's drive transmission mechanism is equipped with an oil injection unit. The needle valve oil cup in the oil injection unit can automatically drip lubricating oil into the transmission part of the drive transmission mechanism, thus replacing manual oiling and significantly reducing labor costs. At the same time, the dripping volume and dripping rate of the needle valve oil cup can be adjusted, thereby avoiding errors and omissions that occur with manual oiling. It can also ensure that the transmission part of the drive transmission mechanism is always immersed in oil, improving the efficiency of lubricating oil use. Attached Figure Description

[0021] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0022] like Figure 1 - Figure 3 As shown, this embodiment provides an automatic oiling mechanism, including a material selection conveyor belt 1, with a drive transmission mechanism 2 installed at its end. The drive transmission mechanism 2 is used to drive the material selection conveyor belt 1 to work, and a collection cover 4 is installed on the material selection conveyor belt 1. An oiling part 3 is installed on the outside of the drive transmission mechanism 2 and is used to drip lubricating oil onto the transmission part of the drive transmission mechanism 2. The oiling part 3 of the conveyor belt can automatically drip lubricating oil onto the transmission part of the drive transmission mechanism 2, thereby replacing the manual oiling method, which can significantly reduce the consumption of manpower. At the same time, the automatic mechanical oiling method can also avoid the errors and omissions that exist in manual oiling.

[0023] The oil filling section 3 includes an isolation cover 31 with a threaded hole at its top, through which a needle valve oil cup 32 is threadedly connected. The oil outlet of the needle valve oil cup 32 is vertically downward. An oil recovery tank 33 is provided at the bottom of the isolation cover 31, through which an oil recovery pipe is connected. The needle valve oil cup 32 can automatically drip lubricating oil into the transmission part of the drive transmission mechanism 2, thereby replacing manual filling and significantly reducing labor costs. At the same time, the dripping volume and dripping rate of the needle valve oil cup 32 can be adjusted, thus avoiding errors and omissions that occur with manual oil filling. It can also ensure that the transmission part of the drive transmission mechanism 2 is always in an oil-immersed state, improving the efficiency of lubricating oil use. The lubricating oil dripping under gravity will be discharged from the oil recovery tank 33 and can be recycled to reduce costs.

[0024] In addition, such as Figure 5 As shown, the above-mentioned automatic oiling solution can also be used in a feeding conveyor belt that works in conjunction with the material selection conveyor belt 1. The feeding conveyor belt is similar to the material selection conveyor belt 1 in terms of working principle and structure. It is driven by the drive transmission mechanism 2 installed inside it. The feeding conveyor belt is equipped with a needle valve type oil cup 32 facing the drive transmission mechanism 2, which can automatically drip lubricating oil to lubricate the drive transmission mechanism 2. This lubrication method is consistent with the automatic lubrication method of the material selection conveyor belt 1.

[0025] In the above technical solution, the needle valve type oil cup 32 consists of a transparent container and a needle valve. The transparent container is convenient for observing the oil level, while the needle valve is used to regulate the flow rate of lubricating oil. The oil cup is mostly made of light metals such as aluminum or aluminum alloy to form the frame, and the inspection hole of the cup wall is mostly made of transparent plastic or glass. By adjusting the opening and closing degree of the nozzle, the operator can control the supply of lubricating oil to meet the needs of different mechanical parts.

[0026] like Figure 3As shown, the material selection conveyor belt 1 includes a side frame 11, in which a belt body 12 is installed. A drive roller 13 for driving the belt body 12 is installed at the end of the side frame 11. The above structure constitutes the most basic structure of the material selection conveyor belt 1. When the drive roller 13 is driven to rotate by an external force, it can drive the belt body 12 to move and complete the material conveying. The drive transmission mechanism 2 includes a mounting plate 21 mounted on the side frame 11, on which a drive motor 22 is installed. The output shaft of the drive motor 22 is fixedly connected to a drive sprocket 23. A driven sprocket 24 is fixedly connected to the end of the drive roller 13. The drive sprocket 23 and the driven sprocket 24 are connected by a chain 25. In the above structure, the drive sprocket 23, the driven sprocket 24 and the chain 25 constitute the transmission structure of the drive transmission mechanism 2, which transmits the torque output by the drive motor 22 to the drive roller 13, causing it to rotate.

[0027] like Figure 1 - Figure 2 As shown, the drive sprocket 23, driven sprocket 24, and chain 25 are all located inside the isolation cover 31, and the needle valve oil cup 32 is located directly above the above three, with the oil outlet of the needle valve oil cup 32 aligned with the chain 25. This structure ensures that the transmission structure of the drive transmission mechanism 2 is within the protection range of the isolation cover 31, preventing foreign objects from entering and causing increased wear. At the same time, the position of the needle valve oil cup 32 ensures that the falling lubricating oil can directly wet the chain 25, improving the efficiency of lubricating oil use.

[0028] like Figure 4 As shown, the collection hood 4 includes a housing 41 with a collection port 42 facing downwards at the bottom. A front baffle 43 facing the collection port 42 is installed inside the housing 41, and a side baffle 44 is installed on the side of the housing 41 near the drive transmission mechanism 2. When the air blowing screening equipment blows up the material that meets the standard, it will enter the housing 41 through the collection port 42 and fall onto the material selection conveyor belt 1 under the action of gravity and be transported away. The front baffle 43 and the side baffle 44 can play a role in shielding and isolating, restricting the flying material to fall onto the material selection conveyor belt 1 in the designated area, so that it can be transported away smoothly.

[0029] The working principle and usage process of this utility model:

[0030] The drive transmission mechanism 2 of the conveyor belt is equipped with an oil injection section 3. The needle valve type oil cup 32 in the oil injection section 3 can automatically drip lubricating oil into the transmission part of the drive transmission mechanism 2, thereby replacing the manual injection method and significantly reducing the labor cost. At the same time, the dripping volume and dripping rate of the needle valve type oil cup 32 can be adjusted, thus avoiding the errors and omissions that exist in manual oil injection. It can also ensure that the transmission part of the drive transmission mechanism 2 is always in an oil-immersed state, improving the efficiency of lubricating oil use.

[0031] Meanwhile, the drive sprocket 23, driven sprocket 24, and chain 25 are all located inside the isolation cover 31, and the needle valve oil cup 32 is located directly above the above three, with the oil outlet of the needle valve oil cup 32 aligned with the chain 25. This structure ensures that the transmission structure of the drive transmission mechanism 2 is within the protection range of the isolation cover 31, preventing foreign objects from entering and causing increased wear. At the same time, the position of the needle valve oil cup 32 ensures that the falling lubricating oil can directly wet the chain 25, improving the efficiency of lubricating oil use.

[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
