Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco production, and particularly relates to a bottom belt side chain bearing mechanism for a cigarette storage cabinet and a lubrication system thereof. Background Art

[0002] In the tobacco industry's silk production line, tobacco storage cabinets are a widely used storage equipment. Each batch of production materials weighs thousands of kilograms, so the storage cabinets for storing materials have the characteristics of large volume and heavy operating load. Tobacco storage cabinets mostly use a bottom belt side chain bearing mechanism. If the bottom belt chain pin lacks lubrication, it will produce a large friction resistance, which will easily cause the chain to get stuck, dead knot, wear and noise, and even cause the bottom belt drive shaft or drive chain to break.

[0003] At present, the industry mainly uses manual lubrication to lubricate the bottom belt chain of cigarette storage cabinets. The lubricant is sprayed on the nodes of the bottom belt chain to produce an oil film on the pin shaft, thereby reducing the friction between the load-bearing wheel and the pin shaft. Since the cigarette storage cabinet is large in size and has many lubrication points, manual lubrication is labor-intensive and time-consuming; and the oil film produced by the filling lubricant spray is thin and easy to evaporate, so the effect and durability of manual lubrication are poor; due to the lack of automatic detection devices, manual lubrication is in the form of regular lubrication, which is easy to cause repeated lubrication and increase lubrication costs.

[0004] Therefore, in view of the shortcomings of the current manual lubrication method, an integrated automatic detection and lubrication system will be designed based on automatic control technology to improve the lubrication effect of the storage cabinet and enhance the lubrication efficiency.

[0046] Figure 3 This is a schematic diagram of the structure of the support roller jam detection device for the lubrication system provided by the utility model, see Figure 3The wheel jam detection device includes: a detection wheel 27, a detection bracket 28, a trigger bracket 29, a start proximity switch 30, a stop proximity switch 31 and a detection switch 32; a cam edge is formed on the detection wheel 27, the detection wheel 27 is connected to the annular load-bearing chain, the trigger bracket 29 is connected to the annular load-bearing chain, and the trigger bracket 29 corresponds to the position of the detection wheel 27 on the annular load-bearing chain, the detection bracket 28 is arranged below the detection wheel 27, the start proximity switch 30 and the stop proximity switch 31 are respectively connected to the two end positions of the detection bracket 28, a plurality of the detection switches 32 are connected to the detection bracket 28 and are located between the start proximity switch 30 and the stop proximity switch 31, and can make the cam edge on the detection wheel 27 contact with the detection switch 32.

[0047] See also Figure 3 In a preferred embodiment, the detection switch 32 includes a pressing body 321, a supporting body 322, a spring 323 and a pressing switch 324, the supporting body 322 is connected to the detection bracket 28, the spring 323 is arranged in the supporting body 322, the pressing body 321 is connected to the supporting body 322 and connected to the spring 323, and the spring 323 is connected to the pressing switch 324.

[0048] Figure 6 This is a schematic diagram of the structure of the pressing body provided by the utility model, see Figure 6 The pressing body 321 includes a pressing plate 3211 and a pressing column 3212 connected to the pressing plate 3211, protrusions are formed on both sides of the pressing column 3212, and the protrusions are connected to the inner side of the support body 322. The pressing column 3212 can move on the support body 322 through the protrusions. The pressing column 3212 is connected to the spring 323, and the pressing plate 3211 is located outside the support body 322.

[0049] Specifically, the difference between the detection roller 27 and the load-bearing roller 3 is that a cam edge 270 is formed on the detection roller 27, and the cam edge 270 of the detection roller 27 is used to trigger the detection switch 32 to determine the stuck state of the load-bearing roller 3. The number of the detection rollers 27 installed and the arrangement of the detection rollers in the annular load-bearing chain can be freely selected according to the cabinet model. The detection bracket 28 is arranged directly below the roller rim 4 of the load-bearing roller 3, and the cam edge 270 of the detection roller 27 can just trigger the detection switch 32.

[0050] The length of the detection bracket 28 should be greater than 3 times the circumference of the load-bearing roller 3. The start proximity switch 30 and the end proximity switch 31 are respectively located at the head and tail sides of the detection bracket 28, and a plurality of numbered detection switches 32 are arranged in a row on the detection bracket 28.

[0051] When the pressing body 321 on the detection switch 32 is pressed, it will overcome the elastic force of the spring 323 and move along the inner side of the support body 322, thereby triggering the pressing switch 324. After the force is applied, the pressing body 321 can automatically return to its original position under the action of the elastic force of the spring 323.

[0052] As the annular load-bearing chain moves as a whole, the trigger bracket 29 outside the detection wheel 27 will trigger the starting proximity switch 30 and the ending proximity switch 31 successively. During this period of time, the detection wheel 27 moves forward in a circular motion along the load-bearing track 9, so that the cam edge 270 on the detection wheel 27 will have the opportunity to press the detection switch 32.

[0053] Among them, when the following situation occurs: three consecutive numbered detection switches 32 are pressed and the number of pressed detection switches 32 is less than two, it is determined that the load-bearing support wheel 3 is in a stuck state. The above judgment conditions can be adjusted according to the cabinet model. The control program setting, the support wheel stuck detection device sends the detection result information to the control unit and the host computer.

[0057] Specifically, in order to ensure a good sound insulation effect and prevent external noise from interfering with the detection system, the sound analysis sensor 35 is located in the middle of the sound insulation channel to better collect the abnormal noise of the load-bearing roller 3 entering the sound insulation channel. The head of the sound analysis sensor 35 is a trumpet-shaped sound inlet cover 351. The head of the sound inlet cover 351 is installed with the dust cover 352. The dust cover 352 keeps the sound channel 353 at the rear clean. Several silencer cavities 355 are arranged on both sides of the sound channel 353, and the silencer cavities 355 are filled with sound-absorbing materials. This structure is to ensure that the sensor can eliminate the interference of sounds from other directions and directionally collect the noise in the sound insulation channel. The sensor 356 is located at the end of the sound channel 353. The abnormal sound emitted by the pin shaft of the load-bearing roller 3 due to wear is collected and converted into an electrical signal by the analyzer 354 and the sensor 356, and sent to the host computer through the communication unit. An audio database of abnormal sounds of the load-bearing roller under different wear conditions is established in the host computer in advance. The audio signal emitted by the sensor is judged by comparing the database to be an abnormal sound caused by wear. If the frequency of the abnormal sound caused by wear is higher than the set threshold, an alarm will be issued and an instruction will be sent to the control unit of the automatic lubrication system.

[0058] In the above-mentioned wear and noise detection device, in order to better collect audio signals, the upper sound insulation channel 33 and the lower sound insulation channel 34 form an annular sound insulation channel, and the annular sound insulation channel wraps the annular load-bearing chain, and the load-bearing support wheel 3 and the chain plate are wrapped by the sound insulation channel. In order to enable the dropper 14 in the automatic lubrication device to drip oil into the lubricating oil channel 8 while ensuring good audio collection, the dropper 14 is extended into the sound insulation channel.

[0059] The utility model also provides a lubrication method for a side chain bearing mechanism of a bottom belt of a cigarette storage cabinet, the lubrication method adopts the lubrication system described above, and the lubrication method comprises:

[0060] S1. Connect the lubrication solenoid valve 13 to a control unit, and the control unit is connected to a host computer.

[0061] S2. Detect the wear and noise of the pin shaft of the supporting roller 3 in the annular supporting chain in the side chain supporting mechanism of the bottom belt of the tobacco storage cabinet by using a wear and noise detection device and generate a first electrical signal, or detect the jamming of the supporting roller 3 in the annular supporting chain in the side chain supporting mechanism of the bottom belt of the tobacco storage cabinet by using a supporting roller jam detection device and generate a second electrical signal, and transmit the first electrical signal and the second electrical signal to the host computer.

[0062] S3. The host computer identifies and processes the first electrical signal and the second electrical signal to form corresponding first control signals and second control signals respectively, and the control unit controls the automatic lubrication device to lubricate the annular load-bearing chain according to the first control signal and the second control signal.

[0063] In the above-mentioned lubrication method for the side chain bearing mechanism of the bottom belt of the cigarette storage cabinet, the host computer, the communication unit and the control unit are used to realize the conversion of the collected data, so that automatic lubrication can be realized.

[0064] In a preferred embodiment, the host computer is provided with an abnormal sound audio database of the support wheel 3 under different conditions, and the host computer performs data pairing between the first electrical signal and the abnormal sound audio database to form a first control signal which is transmitted to the control unit.

[0065] In a preferred embodiment, the control unit can respectively identify the first control signal and the second control signal to respectively control the automatic lubrication device to lubricate the annular load-bearing chain; or when the control unit simultaneously identifies the first control signal and the second control signal, the control unit can control the automatic lubrication device to lubricate the annular load-bearing chain according to the first control signal or the second control signal.

[0066] To sum up, the wear and abnormal noise detection device collects abnormal noises caused by wear of the bottom belt side chain bearing mechanism, and uses database technology to compare it with the abnormal noise audio database to determine whether the abnormal noise is caused by wear. If the frequency of the abnormal noise caused by wear is higher than the set value, it means that the pin shaft of the bearing mechanism is severely worn, and an instruction is issued to the control unit of the automatic lubrication device.

[0067] The roller jam detection device understands the entire side chain bearing mechanism by judging the jam state of each detection roller 27. If the number of detection rollers 27 judged to be jammed on one of the annular bearing chains is greater than a set value, it means that the entire bottom belt side chain bearing mechanism needs lubrication. At this time, the roller jam detection device sends a command to the control unit of the automatic lubrication device.

[0068] The automatic lubrication device will enter the startup state after receiving the instruction from the roller jam detection device or the wear and abnormal noise detection device. The electromagnetic pump 17 will pump the lubricating oil in the main oil tank 16 into the temporary oil tank 12 according to the oil level in the temporary oil tank 12. The photoelectric detection device 10 determines whether the load-bearing roller 3 has entered the lubrication point. When the load-bearing roller 3 enters the lubrication point, the lubrication electromagnetic valve 13 is opened to allow the lubricating oil to flow from the dropper 14 to the lubricating oil channel 8 to complete the lubrication process. The control unit will count each time a lubrication process is completed. When all the load-bearing rollers 3 on the entire bottom belt side chain load-bearing mechanism have completed the lubrication process, the automatic lubrication device will open the return electromagnetic valve 18 to return the lubricating oil to the main oil tank 16, and then the automatic lubrication device will be closed and wait for the next lubrication instruction.
