Description

Technical Field

[0001] The utility model relates to the technical field of cigarette equipment, in particular to a gear lubrication device. Background Art

[0002] The cigarette making machine is equipped with a merging drum, a closing drum, a rubbing drum, a rejecting drum and a cigarette replenishing drum. The cigarette making machine absorbs filter rods, cigarettes and finished cigarettes through the negative pressure in each drum, and transports the filter rods, cigarettes and finished cigarettes to the downstream process through the rotation of the drum. Among them, each drum is connected to the driving mechanism by a transmission gear to ensure the consistency of the rotation of each drum. However, the transmission gears are prone to high temperatures when running for a long time, causing the lubricating oil between the gears to evaporate. If the lubricating oil is not replenished in time, it is easy to cause wear at the gear meshing point, affecting the transmission stability. In the prior art, in order to ensure safety, the operator needs to apply lubricating oil to the surface of the transmission gear when the cigarette making machine is shut down. Not only is the lubrication efficiency extremely low, but the cigarette making machine needs to be shut down every time the gears are lubricated, which also seriously slows down production efficiency.

[0029] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] The embodiment of the utility model provides a gear lubrication device for lubricating the transmission gear 5 of the cigarette making machine 6, such as Figure 1 As shown, the gear lubrication device includes an oil tank 1, an oil pump 2, an oil pressure sensor 3 and a control system. The oil tank 1 contains lubricating oil. The input end of the oil pump 2 is connected to the oil tank 1, and the output end is connected to the gear box 4 of the cigarette making machine 6. The transmission gear 5 is arranged in the gear box. The detection end of the oil pressure sensor 3 is arranged at the output end of the oil pump 2, and is used to detect the oil pressure at the output end of the oil pump 2. The control system is electrically connected to the oil pump 2, the oil pressure sensor 3 and the cigarette making machine 6, and the control system is used to control the operation of the oil pump 2 and the cigarette making machine 6 according to the oil pressure.

[0031] By adopting the above technical solution, the lubricating oil in the oil tank 1 is pumped into the gear box 4 of the cigarette making machine 6 through the oil pump 2 to lubricate the transmission gear 5 of the cigarette making machine 6, and the operation of the oil pump 2 and the cigarette making machine 6 is controlled according to the oil pressure at the output end of the oil pump 2. Specifically, the control system can adjust the output efficiency of the oil pump 2 according to the oil pressure at the output end of the oil pump 2 to control the oil pressure within a reasonable range, so that the lubricating oil can flow into the gear box 4 at a reasonable flow rate to ensure the lubrication effect of the transmission gear 5. Compared with the situation of manually lubricating the transmission gear 5 in the prior art, the embodiment of the present application does not require the cigarette making machine 6 to be stopped when adding lubricating oil to the gear box 4, which can greatly improve the gear lubrication efficiency and production efficiency.

[0032] Furthermore, when the oil pressure is greater than or equal to the preset value, the oil pressure sensor 3 outputs a first detection signal, and when the oil pressure is less than the preset value, the oil pressure sensor 3 outputs a second detection signal. The control system can control the operation of the oil pump 2 and the cigarette making machine 6 according to the first detection signal and the second detection signal. When the control system receives the second detection signal, it means that the oil pressure output by the oil pump 2 is less than the preset value, and the gear box 4 may be insufficiently supplied with oil, and the output efficiency of the oil pump 2 needs to be improved to meet the oil supply needs of the gear box 4. When the control system receives the first detection signal, it means that the oil pressure output by the oil pump 2 is greater than or equal to the preset value. If the oil pressure sensor 3 is not faulty, the oil supply of the gear box 4 is normal.

[0033] Further, in order to reduce energy consumption, the oil pump 2 can be designed to intermittently supply oil to the gear box 4, that is, the oil pressure is allowed to be greater than or equal to the preset value and stop supplying oil after a certain period of time, and then continue to supply oil after another delay, and cycle in sequence. Specifically, the control system includes a timer and a processor. Among them, the timer is electrically connected to the oil pressure sensor 3, and the timer is used to count the duration of the first detection signal and the second detection signal. The processor is electrically connected to the timer and the oil pump 2. When the duration of the first detection signal is greater than or equal to the first preset duration, the processor controls the oil pump 2 to run or stop running at the first output efficiency. The processor is also used to control the oil pump 2 to run at the second output efficiency when the duration of the second detection signal is greater than or equal to the second preset duration. Among them, the first preset duration is 10 seconds, and the second preset duration is 9 minutes, that is, the oil pump 2 supplies oil for 10 seconds every 9 minutes.

[0034] Furthermore, the second output efficiency is greater than the first output efficiency. Specifically, the first output efficiency may be zero or non-zero. When the first output efficiency is zero, the oil pump 2 is in a shutdown state, and the oil pump 2 stops after completing a certain stage of oil supply work, which can reduce energy consumption; when the first output efficiency is not zero, the oil pump 2 runs at a low speed, which is convenient for reducing the resistance of the oil pump 2 to speed up during the next oil supply, so as to increase the service life of the oil pump 2.

[0035] Furthermore, the gear lubrication device further comprises an alarm, and the processor is electrically connected to the alarm and the cigarette making machine 6. The processor can control the alarm to sound an alarm and control the cigarette making machine 6 to stop when the duration of the second detection signal is greater than or equal to the third preset duration, or when the duration of the first detection signal is greater than or equal to the fourth preset duration. If the oil pressure sensor 3 continuously outputs the second detection signal, it indicates that the oil pump 2 may fail or the oil tank 1 may be insufficient. At this time, the cigarette making machine 6 needs to be stopped to avoid wearing the transmission gear 5. In some embodiments of the present application, in order to avoid the oil pressure sensor 3 or its wire from erroneously continuously outputting the first detection signal or the second detection signal due to a failure, the oil pump 2 and the cigarette making machine 6 are also controlled to operate according to the duration of the first detection signal and the second detection signal. Specifically, the third preset duration is 20 minutes, and the fourth preset duration is 2 minutes. When the duration of the second detection signal is greater than or equal to 20 minutes, it indicates that the oil pressure of the oil pump 2 has not reached the preset value within 20 minutes, and the oil pump 2 may fail and cannot supply oil to the gear box 4. At this time, controlling the cigarette making machine 6 to stop can avoid the wear of the transmission gear 5. When the first detection signal lasts for more than or equal to 2 minutes, it means that the oil pump 2 does not stop supplying oil in time, or there is a fault in the oil pressure sensor 3. At this time, the cigarette making machine 6 needs to be stopped to eliminate the fault of the oil pump 2 or the oil pressure sensor 3.

[0036] Furthermore, a current sensor is included, which is electrically connected to the driving mechanism and the control system of the cigarette making machine 6. The current sensor is used to output a shutdown signal when the driving mechanism stops. The control system can control the oil pump 2 to run for 1 to 2 minutes upon receiving the shutdown signal. The lubricating oil fully soaks the transmission gear 5, cools the transmission gear 5, and prevents the lubricating oil on the transmission gear 5 from evaporating at high temperature, resulting in insufficient lubrication between the gears.

[0037] Furthermore, if Figure 1 As shown, an input port 7 is provided above the gearbox 4, and the output end of the oil pump 2 is connected to the input port 7 through a pipeline. The lubricating oil enters the gearbox 4 from the input port 7 and can flow through the surface of the gear to improve the wetting effect. The oil tank 1 is provided below the gearbox 4, and an oil outlet is provided at the bottom of the gearbox 4. The oil outlet is connected to the oil tank 1, so that the lubricating oil in the gearbox 4 flows into the oil tank 1 for the oil pump 2 to take.

Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
