Description

Technical Field

[0001] The invention relates to a lubricating device, in particular to a lubricating device for a chain plate of a cigarette conveying line. Background Art

[0002] At present, most cigarette factories use cigarette overhead conveyors to transport finished cigarettes produced by packaging machines to the box filling area for centralized box filling. If the box filling area is far away from the packaging machine, multiple cigarette overhead conveyors are used for relay transmission. The cigarette overhead conveyor consists of chain plates, slideways, driving sprockets, tail wheels, and power heads. The polymer chain plates are connected to form a chain belt. The power head drags the chain belt through the driving sprocket to slide on a specific nylon slideway. When the polymer chain belt slides on the nylon slideway, the friction between the two generates static electricity. The longer the transmission distance and the longer the chain belt, the more static electricity is generated on the surface of the chain belt. When the chain plate is running, the static electricity on the surface absorbs the smoke generated during production and maintenance in the workshop air, and the wear particles generated by the friction between the chain plate and the nylon slideway. As the cigarette conveyor runs for a long time, the chain belt absorbs more and more dust. The dust slowly falls to the inside of the chain plate and is compacted on the chain plate when passing through the active sprocket, which increases the friction and resistance of the chain plate sliding on the nylon slide. The chain belt operation changes from a uniform speed to irregular twitching and crawling, causing the cigarettes to shake on the chain belt. Blockage occurs when the two-level cigarette conveyor devices are connected. In severe cases, the chain belt breaks. It takes more than half an hour for three maintenance workers to use climbing equipment to reconnect the chain belt, seriously affecting normal production.

[0003] When the chain belt is found to be twitching and creeping, the traditional approach is to spray lubricants such as silicone oil or paraffin inside the chain belt to lubricate and reduce friction. 5-10 minutes after the lubricant is sprayed, the chain belt twitching and creeping phenomenon disappears immediately. After long-term or multiple spraying of lubricants, the lubricant and dust accumulate to form sludge, which causes greater friction between the chain plate and the nylon slideway, and finally makes the lubricant ineffective. The entire cigarette conveyor chain needs to be disassembled and disassembled into chain plates for cleaning, which is time-consuming and labor-intensive. Summary of the invention

[0004] The purpose of the present invention is to provide a lubricating device for a chain plate of a cigarette conveyor line to solve the deficiencies in the prior art.

DETAILED DESCRIPTION

[0016] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0017] Embodiments of the present invention: Figure 1-3 As shown, a lubricating device for a chain plate of a cigarette conveyor line, wherein the chain plate conveyor line comprises a profile 1, a conveyor chain plate 2 and a nylon guide rail 3, the profile 1 is used to support and fix the nylon guide rail 3, as shown in FIG. Figure 1 As shown, a plurality of nylon guide rails 3 are arranged on the profile 1, and the profile 1 is also used to separate adjacent conveying chain plates 2. The nylon guide rails 3 are fixed to the profile 1 through an I-shaped support beam 4. The nylon guide rails 3 are annular in structure as a whole, and are used to carry the conveying chain plates 2. The conveying chain plates 2 are slidably mounted on the nylon guide rails 3; the lubrication device includes an oil storage device 5, a peristaltic pump 6, a solenoid valve module 7 and a lubrication module 8 which are sequentially connected through oil pipes. A plurality of mounting holes 9 are opened on the nylon guide rail 3, and a lubrication module 8 is mounted on each mounting hole 9.

[0018] Specifically, the mounting hole 9 is formed on the top surface of the nylon guide rail 3, and lubrication holes 10 are provided on both side surfaces of the nylon guide rail 3. The lubrication module 8 includes a housing 11, a cover plate 12, a felt 13 and an oil pipe quick connector 16. The housing 11 includes a felt mounting portion and a housing fixing portion. The felt mounting portion is higher than the housing mounting portion. A through groove 14 is formed on the felt mounting portion along the width direction of the housing 11. A threaded hole 21 for mounting the oil pipe quick connector 16 is formed at the bottom of the housing 11. The threaded hole 21 is connected to the through groove 14. The upper end of the oil pipe quick connector 16 is fixed in the threaded hole 21 by thread. The felt 13 is accommodated in the through groove 14. The cover plate 12 is fixed to the mounting portion by bolts. A through hole 15 is provided on the cover plate 12. A mounting hole 17 is formed on the mounting portion. The length of the felt 13 is greater than the length of the through groove 14. A protrusion 18 is provided on the top surface of the felt 13. The protrusion 18 extends out of the cover plate 12 through the through hole 15.

[0019] During installation, the felt 13 is placed in the through groove 14, and then the through hole 15 on the cover plate 12 is aligned with the raised portion 18 on the top of the felt 13, and then the cover plate 12 is fixed to the housing 11 using a bolt assembly, and then the felt mounting portion is aligned with the mounting hole 9 on the nylon guide rail 3, and the housing 11 is fixed to the nylon guide rail 3 using screws through the mounting holes 17 on the housing mounting portion. After installation, the top surface of the cover plate 12 should be flush with the top surface of the nylon guide rail 3. In order to ensure the lubrication effect, the two ends of the felt 13 should extend out of the through groove 14 and the lubrication holes 10 on both sides of the nylon guide rail 3, and the raised portion 18 on the top of the felt 13 should be higher than the top surface of the nylon rail 3. In addition, in this embodiment, the body of the felt 13 and the raised portion 18 on its top are preferably designed as a rectangular parallelepiped structure. Accordingly, the lubrication hole 10 and the mounting hole 9 should also be rectangular holes.

[0020] Through the above-mentioned structural design, when the conveying chain plate 2 slides on the nylon guide rail 3, its two side surfaces and the bottom surface can contact the felt 13. The lubricating oil on the felt 13 can lubricate the conveying chain plate 2, not only without forming sludge, but also ensuring that the chain plate always maintains a uniform speed of movement.

[0021] Further, in this embodiment, the oil storage device 5 is an oil storage tank, and the end of the oil pipe connected to the oil storage tank is provided with a filter joint 19, and the filter joint 19 is used to filter impurities in the oil to prevent blockage. A one-way valve 20 is provided on the oil pipe between the peristaltic pump 6 and the solenoid valve module 7. The one-way valve 20 can prevent the lubricating oil from flowing back and ensure the accuracy of the oil supply of the peristaltic pump 6.

[0022] In combination with the above structure, a specific lubrication method is provided, comprising the following steps:

[0023] The PLC controller collects the current current value of the driving motor set on each nylon track 3. When the current current value of the driving motor on a certain nylon track 3 is greater than its rated current value, the controller controls the peristaltic pump 6 to work and controls the solenoid valve connected to the lubrication module 8 on the nylon guide rail 3 to open;

[0024] The peristaltic pump 6 draws the lubricating oil in the oil storage device 5 from the oil storage device 5 through the filter joint 19, passes through the one-way valve 20, and is added to the felt of the lubricating module 8 through the corresponding solenoid valve opened on the solenoid valve module 7 and the oil pipe quick joint 16. The gap between the felt 13 and the conveying chain plate 2 is 2mm. When the conveying chain plate 2 is running, the felt 13 evenly applies the lubricating oil to the inner surface of the conveying chain plate 2. The peristaltic pump 6 realizes precise quantitative lubrication to avoid the lubricating oil pollution of the environment and the conveyed goods caused by lubrication methods such as brush application, spraying and dripping. When the current current value of the driving motor is equal to the rated current value, the PLC controller controls the peristaltic pump 6 and the corresponding solenoid valve to close.

[0025] The structure of the present invention is used to lubricate the conveyor chain plate 2, which will not cause excessive oiling, thereby solving the problem of oil sludge generation, thereby ensuring that the conveyor chain plate 2 can always slide smoothly.

[0026] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
