Description

Technical Field

[0001] This utility model relates to the field of refueling machine technology, specifically to a refueling machine for lubricating the side chain of the screen in a tobacco re-drying machine. Background Technology

[0002] Tobacco curing is a process that controls the internal moisture content of tobacco leaves within a certain range to preserve the flavor and facilitate storage.

[0003] Traditional tobacco curing processes primarily involve fixed-hanging re-drying and threshing re-drying. With increased mechanization in production, existing technologies have proposed using mesh screens for material transport in conjunction with tobacco re-drying machines. This approach significantly improves production efficiency but also has some drawbacks. For example, existing mesh screens move reciprocally via side rollers. To ensure the normal operation and extend the lifespan of these side rollers, lubrication is typically achieved using a spray nozzle from an oiling machine. However, the spray nozzles have low positioning accuracy and are difficult to adjust, making it challenging to guarantee effective lubrication and easily leading to a dirty production area. Furthermore, existing oiling machines lack cleaning capabilities, resulting in oil buildup on the roller surfaces, causing roller deformation and affecting the normal operation of the mesh screen. Utility Model Content

[0004] This utility model is designed to avoid the shortcomings of the existing technology mentioned above, and provides a side chain lubrication and refueling machine for the screen of a tobacco re-drying machine.

[0005] The present invention adopts the following technical solution to solve the technical problem: a side chain lubrication and oiling machine for a tobacco re-drying machine, wherein multiple rollers are arranged in rows on both sides of the screen, and a platform is provided at the bottom of each roller. The screen is connected to a drive motor for driving it to reciprocate on the platform through each roller. A base plate is fixedly installed on the side of the platform, and a positioning mechanism including a sleeve, a sliding sleeve, a sliding rod, a positioning structure and a locking structure is provided. A slide rail is provided on the base plate.

[0006] The ferrule is slidably mounted on the slide rail, forming a sliding pair parallel to the reciprocating motion direction of the screen. A positioning structure is also provided between the two to limit their relative sliding.

[0007] The sliding sleeve is installed and fixed to the sleeve, and the bottom end of the sliding rod is slidably inserted into the sliding sleeve, so that the sliding rod and the sliding sleeve form a sliding pair perpendicular to the upper surface of the substrate; and a locking structure is provided to limit the relative sliding of the two.

[0008] It is also equipped with a spray rod; the spray rod is installed and fixed to the top of the slide rod.

[0009] Furthermore, two positioning mechanisms are provided, and two spray rods are correspondingly provided;

[0010] The two spray rods are respectively used as lubrication spray rods and cleaning spray rods to spray lubricating oil and cleaning fluid;

[0011] The two positioning mechanisms serve as a lubrication positioning mechanism and a cleaning positioning mechanism, respectively, and the corresponding top ends of the slide rods are respectively equipped with the lubrication spray rod and the cleaning spray rod.

[0012] Furthermore, a liquid supply mechanism is provided for supplying liquid to the spray bar;

[0013] The liquid supply mechanism includes a liquid storage tank, a pipeline, and a valve. The liquid storage tank is connected to the spray rod through the pipeline, and the pipeline is equipped with a valve for controlling the connection or disconnection between the liquid storage tank and the spray rod.

[0014] Furthermore, the positioning structure is a positioning bolt;

[0015] The positioning bolt passes through the ferrule and is threadedly fitted to the ferrule. When tightened, it abuts against the slide rail to restrict the relative sliding between the ferrule and the slide rail, and when loosened, it disengages from the slide rail to release the restriction on the relative sliding between the ferrule and the slide rail.

[0016] Furthermore, the locking structure is a locking bolt;

[0017] The locking bolt passes through the sliding sleeve and is threadedly fitted to the sliding sleeve. When tightened, it abuts against the sliding rod to restrict the relative sliding between the sliding rod and the sliding sleeve, and when loosened, it disengages from the sliding rod to release the restriction on the relative sliding between the sliding rod and the sliding sleeve.

[0018] Furthermore, a cleaning mechanism including a bracket, pressure bar, guide tube and brush plate is also provided;

[0019] The guide cylinder has a hollow cylindrical structure and is located directly above the rolling path of the roller. It is installed and fixed to the platform by the bracket, and its axis is set vertically.

[0020] The brush plate is fixedly installed at the bottom end of the pressure rod; the pressure rod is slidably installed inside the guide cylinder, forming a sliding pair with the guide cylinder to support the pressure rod to rise or fall so that the brush plate is away from the roller or to periodically press the brush plate into contact with the roller.

[0021] Furthermore, the cleaning mechanism also includes a spring;

[0022] The top of the pressure rod has a radially outward convex limiting edge structure. The spring is sleeved on the outside of the pressure rod and pressed between the limiting edge structure and the bracket. The elastic force of the spring tends to cause the pressure rod to drive the brush plate to rise.

[0023] Furthermore, the valve is a pneumatic valve.

[0024] Furthermore, a controller is also provided;

[0025] The controller is connected to the spray bar and the pneumatic device that controls the pneumatic valve via data communication.

[0026] Furthermore, a proximity switch that is connected to the controller for data communication is also provided;

[0027] The proximity switch is mounted on the platform, with its detection end facing the rolling path of the roller.

[0028] This utility model provides a side-chain lubrication and oiling machine for a tobacco re-drying machine screen, which has the following beneficial effects:

[0029] 1. The spray bar of this utility model uses a positioning mechanism to adjust its position parallel to the rolling path of the roller. After precise positioning, the spray bar sprays lubricating oil or cleaning fluid onto the roller for lubrication or cleaning. This can better maintain the lubrication of the roller, avoid the accumulation of oil stains that could cause the roller to deform, and help ensure the normal operation of the screen and extend the service life of the roller.

[0030] 2. The brush plate of this utility model can maintain periodic pressing contact with the roller when the pressure bar descends, further cleaning the roller and providing better basic conditions for subsequent lubrication of the roller, so as to better ensure the normal operation and service life of the roller.

[0031] 3. The spray bar and liquid supply mechanism of this utility model can be used in conjunction with a controller and a proximity switch to make the spray bar periodically spray lubricating oil or cleaning water when the roller is close to itself, so as to avoid a large waste of lubricating oil and cleaning fluid and improve the utilization rate of lubricating oil and cleaning fluid.

[0052] Preferably, a cleaning mechanism 6 is also provided, including a bracket 61, a pressure rod 62, a guide cylinder 63, and a brush plate 65;

[0053] The guide cylinder 63 has a hollow cylindrical structure and is located directly above the rolling path of the roller 11. It is installed and fixed to the table 2 by the bracket 61, and its axis is set vertically.

[0063] First, slide the slide bar 43 into the sliding sleeve 42 to a suitable position, such as sliding the slide bar 43 until the height of the lubrication spray bar or cleaning spray bar installed at its top is consistent with that of the roller 11.

[0064] The second step is to slide the ferrule 41 along the slide rail 31 to a suitable position, such as sliding the ferrule 41 to the side of the roller 11 that needs to be lubricated or cleaned, and then tighten the fixing bolt 44 so that the fixing bolt 44 abuts against the slide rail 31, restricting the relative sliding between the ferrule 41 and the slide rail 31.

[0065] The cleaning of the screen rollers using the side-chain lubrication and oiling machine for the tobacco re-drying machine in Example 1 can be performed as follows:

[0066] The position of the cleaning spray bar is adjusted by the positioning mechanism 4 so that the cleaning spray bar is facing the roller 11; then, the valve 73 is opened so that the cleaning liquid in the storage tank 71 reaches the cleaning spray bar through the pipeline 72 and is sprayed onto the roller 11 to clean the roller 11.

[0067] Alternatively, during the reciprocating rolling of the roller 11, the spring force of the spring 64 can be overcome to press down the pressure rod 62, causing the pressure rod 62 to drive the brush plate 65 down until the brush plate 65 and the roller 11 are periodically pressed into contact, so as to clean the surface of the roller 11.

[0068] The screen rollers of the tobacco re-drying machine in Example 1 can be lubricated using the following method:

[0069] The position of the lubrication spray bar is adjusted by the positioning mechanism 4 so that the lubrication spray bar is directly facing the roller 11; then, the valve 73 is opened so that the lubricating oil in the reservoir 71 reaches the lubrication spray bar through the pipeline 72 and is sprayed onto the roller 11 to lubricate the roller 11.

[0070] Example 2

[0071] A side-chain lubrication and refueling machine for a tobacco re-drying machine screen is provided. Valve 73 is a pneumatic valve controlled by a pneumatic device. A controller is added based on the structure of Embodiment 1. The controller is connected to the pneumatic device for data communication.

[0072] The cleaning or lubrication of the screen rollers in the tobacco re-drying machine screen chain lubrication and oiling machine of Example 2 can be performed as follows:

[0073] Based on the periodicity of the reciprocating rolling of the roller 11, the working parameters of the pneumatic device are reasonably set so that the controller controls the pneumatic device to periodically deliver the cleaning fluid or lubricating oil in the storage tank 71 through the pipeline 72 to the cleaning spray bar or lubrication spray bar to spray onto the roller 11 at corresponding time intervals, so as to clean or lubricate the roller 11.

[0077] Based on the periodicity of the reciprocating rolling of the roller 11, the installation position of the proximity switch 8 and the delayed start time of the pneumatic device are set accordingly. The controller controls the periodic start and stop of the pneumatic device according to the trigger signal periodically triggered by the proximity switch 8. This allows the pneumatic device to periodically deliver the cleaning fluid or lubricating oil in the storage tank 71 to the cleaning or lubricating spray bar via the pipeline 72 when the roller 11 is just moving to face the cleaning or lubricating spray bar, and spray it onto the roller 11 to clean or lubricate it.
