Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of tea processing equipment, specifically relating to a lubrication device for a transmission sprocket in tea processing machinery. Background Technology
[0002] In the current tea processing machinery industry, the widespread lack of effective lubrication systems has become a key issue restricting production quality and safety. Most equipment is not equipped with dedicated lubrication devices, leading to reliance on manual application of lubricating oil for maintenance during machine operation.
[0003] This traditional method has three significant drawbacks: First, it poses a prominent safety hazard to personnel. Manual painting requires operation while the machine is running, and work activities near rotating parts are highly likely to cause mechanical injury accidents. In particular, when the equipment is running at high speed, the close contact between the operator and transmission components such as chains and sprockets will greatly increase the risk of workplace injuries.
[0004] Secondly, there are serious hygiene and safety risks. During manual brushing, lubricating oil can contaminate the tea processing environment through the operator's hands, tools, and other media. Especially in open work environments, oil splattering onto the tea surface is common. Since tea processing has extremely high hygiene requirements, this type of contamination will directly affect the microbiological indicators and sensory quality of the finished tea.
[0005] Furthermore, lubrication quality control is difficult. Manual application is prone to arbitrariness, making it difficult to achieve quantitative supply, leading to frequent instances of excessive lubricant dripping or insufficient supply. Excessive lubrication causes oil to flow along equipment surfaces, polluting the production area and wasting resources; insufficient lubrication accelerates wear on transmission components and shortens equipment lifespan. In addition, the intermittent nature of manual operation leads to lubrication interruptions, failing to meet the needs of continuous production. Utility Model Content
[0006] In view of the above-mentioned shortcomings of the prior art, this utility model provides a lubrication device for the transmission sprocket of tea processing machinery, which solves the problems of personnel safety hazards and hygiene safety hazards caused by the reliance on manual application of lubricating oil in existing tea processing machinery.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A lubrication device for a transmission sprocket in tea processing machinery is provided, comprising an oil shell disposed outside the transmission sprocket, forming a lubrication cavity between the oil shell and the transmission sprocket, an oil tank disposed on one side of the oil shell, an oil delivery core disposed inside the oil tank, the oil delivery core being connected to an oil drip nozzle disposed inside the oil shell, and the oil drip nozzle being disposed above the transmission sprocket.
[0008] The beneficial effects of adopting the above technical solution are as follows: The lubrication device for the transmission sprocket of tea processing machinery realizes automatic, slow and continuous lubrication of the transmission sprocket system of tea processing machinery, effectively avoiding the personnel safety hazards and hygiene safety hazards caused by manual application of lubricating oil during the operation of tea processing machinery, and greatly improving the quality of tea processing and the cleanliness of the production environment; wherein, the oil shell is set on the outside of the transmission sprocket and forms a lubrication cavity with the transmission sprocket, which not only provides a relatively sealed lubrication environment for the transmission sprocket, reducing the splashing and contamination of lubricating oil, but also facilitates... The recycling and reuse of residual oil saves lubricating oil resources and reduces production costs. The oil delivery core inside the oil tank uses capillary tension to automatically draw in and absorb lubricating oil, continuously delivering it to the drip nozzle. This ensures a stable supply of lubricating oil without the need for frequent manual operation, improving lubrication efficiency and reliability. The drip nozzle, located inside the oil tank and above the drive sprocket, allows lubricating oil to drip onto the drive sprocket, achieving a slow and continuous lubrication effect. This effectively reduces lubricating oil waste and ensures the long-term, stable operation of the drive sprocket system.
[0009] Furthermore, an injection port is provided at the top of the oil tank, and a drain port is provided at the bottom of the oil tank.
[0010] The beneficial effects of adopting the above technical solution are as follows: the oil tank is equipped with an injection port at the top and a drain port at the bottom, which realizes convenient replenishment and complete drainage of lubricating oil. The injection port facilitates the rapid injection of lubricating oil into the oil tank, ensuring the continuous and stable operation of the lubrication system. The drain port can completely empty the oil tank of residual oil when needed, which facilitates the cleaning and maintenance of the oil tank or the replacement of lubricating oil. This effectively improves the ease of use and maintenance efficiency of the lubrication device, while reducing safety hazards caused by improper manual operation.
[0011] Furthermore, an observation window is provided on the side of the oil tank away from the drive sprocket.
[0012] The beneficial effects of adopting the above technical solution are as follows: setting an observation window on the side of the oil tank away from the transmission sprocket allows operators to more intuitively view the level of lubricating oil in the tank, thereby replenishing the lubricating oil in time and avoiding the risk of oil shortage. At the same time, it eliminates the safety hazards such as entanglement and collision that may occur when manually approaching the machine to apply oil, thus improving operational safety while ensuring the stable operation of the lubrication system.
[0013] Furthermore, an oil collection trough is provided below the oil tank, and an oil drain port is provided below the oil collection trough, with an oil drain plug inside the oil drain port.
[0014] The beneficial effects of adopting the above technical solution are as follows: setting an oil collection tank below the oil tank and setting an oil drain port with an oil drain plug below the oil collection tank can effectively collect residual oil dripping during the lubrication of the transmission sprocket, avoiding the leakage of lubricating oil and contaminating tea leaves or work areas. At the same time, the waste oil accumulated in the oil collection tank can be periodically discharged through the oil drain plug for filtration, recycling or unified treatment, which not only ensures the cleanliness and hygiene of the production environment, but also realizes the recycling of lubricating oil and further reduces operating costs.
[0015] Furthermore, the oil pan and the oil tank are connected by welding.
[0016] Furthermore, the oil delivery element includes an oil delivery pipe and a cotton core disposed inside the oil delivery pipe.
[0017] The beneficial effects of adopting the above technical solution are as follows: The oil delivery core adopts a structure with a cotton core inside the oil delivery pipe. By combining the capillary adsorption of the cotton core with the guiding function of the oil delivery pipe, it can continuously and stably absorb and deliver lubricating oil to the oil drip nozzle through the capillary tension of the cotton core, ensuring that the transmission sprocket receives a uniform and slow lubrication supply. At the same time, the oil delivery pipe can protect the cotton core from external contamination or mechanical damage, thereby extending the service life of the oil delivery core. Furthermore, the synergistic use of the oil delivery core and the oil drip nozzle can replace manual brushing operations, eliminating the safety hazards of manual contact with tea processing machinery.
[0018] In summary, the lubrication device for the transmission sprocket of tea processing machinery provided by this utility model has the following beneficial effects: This lubrication device for the transmission sprockets of tea processing machinery achieves fully enclosed and automated lubrication of the transmission sprocket structure through the coordinated action of an oil shell, oil tank, oil delivery core, and oil drip nozzle. This solves the safety risks and hygiene contamination problems associated with traditional manual lubrication methods. The oil shell covers the transmission sprocket, forming an independent lubrication chamber. This isolates the lubrication area from the external processing environment, preventing lubricating oil from splashing onto the tea surface or worktable during high-speed operation of the transmission sprocket, thus avoiding oil contamination and quality degradation. The sealed structure also reduces the entry of dust, tea dust, and other impurities into the lubrication chamber, thereby reducing the wear rate of the transmission sprocket and chain and extending the machine's service life. The oil tank, located separately on one side of the oil shell, serves as both a storage and supply structure for the lubricating oil. The oil delivery core inside the tank utilizes capillary adsorption, eliminating the need for additional manual lubrication. The system continuously delivers lubricating oil from the tank to the drip nozzle, ensuring the stability of the lubrication process and preventing interruptions or over-lubrication due to mechanical vibration or temperature changes. Simultaneously, the drip nozzle, located within the lubrication chamber and above the drive sprocket, uses a combination of gravity and siphon effect to slowly and evenly drip lubricating oil in the form of fine droplets onto the sprocket teeth and chain nodes, forming a continuous oil film to reduce friction and wear. The dripping speed is matched to the drive sprocket speed, preventing both excessively fast dripping (leading to waste or leakage) and insufficient lubrication (leading to insufficient lubrication). Furthermore, the entire device integrates lubricating oil storage, delivery, and dripping into a closed system, eliminating the safety hazards of manual application where operators must approach the high-speed sprocket, such as entanglement or cuts. Timed and metered lubrication also reduces mechanical failure rates, ultimately achieving safe, efficient, and clean tea processing. Attached Figure Description

Detailed Implementation
[0020] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.
[0021] like Figure 1 and Figure 2 As shown, the lubrication device for the transmission sprocket of tea processing machinery provided by this utility model includes an oil shell 2, which is disposed outside the transmission sprocket 1. A lubrication cavity 3 is formed between the oil shell 2 and the transmission sprocket 1. An oil tank 4 is disposed on one side of the oil shell 2. The oil tank 4 is connected to the oil shell 2 by welding. An oil delivery core 5 is disposed inside the oil tank 4. The oil delivery core 5 is connected to an oil drip nozzle 6. The oil drip nozzle 6 is disposed inside the oil shell 2. A sponge 17 is disposed inside the oil drip nozzle 6. The oil drip nozzle 6 is disposed above the transmission sprocket 1.
[0022] This lubrication device for the transmission sprockets of tea processing machinery enables automatic, slow, and continuous lubrication of the transmission sprocket 1 system of the tea processing machinery 16. It effectively avoids the safety and hygiene hazards associated with manual application of lubricating oil during the operation of the tea processing machinery 16, significantly improving the quality of tea processing and the cleanliness of the production environment. Specifically, the oil tank 2 is located outside the transmission sprocket 1 and forms a lubrication cavity 3 between it and the transmission sprocket 1. This not only provides a relatively sealed lubrication environment for the transmission sprocket 1, reducing oil splashing and contamination, but also facilitates the recovery and reuse of residual oil. This design saves lubricating oil resources and reduces production costs. The oil delivery core 5 inside the oil tank 4 automatically draws in and absorbs lubricating oil using capillary tension, continuously delivering the lubricating oil to the drip nozzle 6. This ensures a stable supply of lubricating oil without the need for frequent manual operation, thus improving lubrication efficiency and reliability. The drip nozzle 6 is located inside the oil shell 2 and above the transmission sprocket 1, allowing lubricating oil to drip onto the transmission sprocket 1, achieving a slow and continuous lubrication effect. This effectively reduces lubricating oil waste and ensures the long-term and stable operation of the transmission sprocket 1 system.
[0023] like Figure 1 and Figure 2As shown, the oil delivery core 5 includes an oil delivery pipe 13 made of materials such as a PVC transparent outer tube and a cotton core 14 disposed inside the oil delivery pipe 13. In use, the cotton core 14 acts as an oil-absorbing medium, continuously absorbing lubricating oil from the oil tank 4 using the capillary tension between its fibers, and evenly delivering the lubricating oil to the oil drip nozzle 6 through the fiber gaps. This avoids the safety and hygiene hazards associated with manual lubrication application. Simultaneously, the oil delivery pipe 13 serves as the outer protective structure of the cotton core 14, preventing external dust, tea dust, and other impurities from entering the cotton core 14, thus keeping the oil path clean and extending the service life of the oil delivery core 5. Furthermore, by utilizing the capillary absorption function of the oil delivery core 5, automatic and continuous lubricating oil delivery can be achieved without an external power source, relying solely on physical properties. This reduces the complexity of the device, eliminates the safety hazards of operators contacting high-speed components during manual application, reduces lubricating oil waste, and improves the cleanliness and safety of the tea processing process.
[0024] like Figure 1 As shown, an inlet 7 is located at the top of the oil tank 4, and a drain port 8 is located at the bottom of the oil tank 4. The presence of the inlet 7 at the top and the drain port 8 at the bottom of the oil tank 4 facilitates convenient replenishment and complete drainage of lubricating oil. The inlet 7 allows for quick injection of lubricating oil into the oil tank 4, ensuring the continuous and stable operation of the lubrication system. The drain port 8 allows for complete drainage of residual oil from the oil tank 4 when needed, facilitating cleaning, maintenance, or oil replacement. This improves the ease of use and maintenance efficiency of the lubrication device, while reducing safety hazards caused by improper manual operation.
[0025] like Figure 1 As shown, an observation window 9 is provided on the side of the oil tank 4 away from the transmission sprocket 1. By providing the observation window 9, the operator can more intuitively view the level of the lubricating oil in the oil tank 4, thereby replenishing the lubricating oil in time to avoid the risk of oil shortage. At the same time, it eliminates the safety hazards such as entanglement and collision that may occur when the operator approaches the tea processing machinery 16 to apply oil, thus improving operational safety while ensuring the stable operation of the lubrication system.
[0026] like Figure 1 As shown, an oil collection trough 10 is provided below the oil tank 2, and an oil drain port 11 is provided below the oil collection trough 10. An oil drain plug 12 is provided inside the oil drain port 11. By providing an oil collection trough 10 below the oil tank 2 and an oil drain port 11 with an oil drain plug 12 below the oil collection trough 10, residual oil dripping during the lubrication of the transmission sprocket 1 can be effectively collected, preventing lubricating oil from leaking and contaminating tea leaves or the work area. At the same time, the waste oil accumulated in the oil collection trough 10 can be periodically discharged through the oil drain plug 12 for filtration, recycling, or unified treatment. This not only ensures the cleanliness and hygiene of the production environment but also realizes the recycling of lubricating oil, further reducing operating costs.
[0027] The method of using the lubrication device for the transmission sprocket of tea processing machinery provided by this utility model is as follows: First, the oil shell 2 is fixed to the frame or equipment of the tea processing machinery 16 through the ear plate 15, ensuring that the oil shell 2 tightly wraps around the outside of the transmission sprocket 1 and forms a closed lubrication cavity 3 with the transmission sprocket 1, thereby isolating the lubrication area from the external processing environment. Then, lubricating oil is added to the oil tank 4 through the oil tank 4 injection port 7 provided on one side of the oil shell 2. The amount added can be controlled to an appropriate liquid level through the observation mirror on the side of the oil tank 4, ensuring that the liquid level is higher than the position of the subsequently connected oil drip nozzle 6. The cotton wick 14 in the oil delivery core 5 inside the oil tank 4 continuously draws lubricating oil from the oil tank 4 using the principle of capillary adsorption and delivers it through the oil delivery pipe 13. The lubricating oil is stably delivered to the drip nozzle 6. When the lubricating oil is delivered to the drip nozzle 6 by the cotton core 14, the sponge 17 inside the drip nozzle 6 further absorbs and slowly releases the lubricating oil, so that the lubricating oil drips slowly onto the tooth surface of the transmission sprocket 1 and the chain nodes in the form of uniform and fine oil droplets, forming a continuous oil film to reduce friction and wear. As the lubrication process continues, the lubricating oil in the oil tank 4 is gradually consumed. The operator can monitor the liquid level in real time through the observation window and replenish the lubricating oil in time when the liquid level is close to the lower limit. If the lubricating oil needs to be replaced, the drain plug 12 under the oil collection tank 10 can be opened to drain the waste oil into the collection container. After filtration, it can be injected back into the oil tank 4 through the injection port 7 to realize the recycling of lubricating oil.
[0028] In summary, the lubrication device for the transmission sprocket of tea processing machinery provided by this utility model integrates the storage, transportation, and dripping of lubricating oil into a closed system through the coordinated work of the oil shell 2, oil tank 4, oil delivery core 5, and oil drip nozzle 6. This completely eliminates the safety accidents such as entanglement and cuts caused by operators having to approach the high-speed rotating sprocket during manual brushing. At the same time, lubrication reduces the mechanical failure rate, achieving safe and efficient tea processing and clean products.
