Description

Technical Field

[0002] Aluminum foil is a crucial packaging material in cigarette packaging. The lubrication system for aluminum foil is essential for smooth packaging. A malfunction in the lubrication system can lead to insufficient lubrication, causing various problems during packaging, such as excessive friction causing poor foil feeding or foil breakage. Excessive lubrication can lower the friction coefficient, causing the foil to drift or become unstable during feeding, affecting packaging precision and appearance. Too much lubricant can also cause the foil to stick together during packaging, resulting in loose packaging and affecting quality and appearance. Furthermore, foil sticking can cause equipment jamming or malfunction, impacting production efficiency and equipment lifespan. Therefore, maintaining the proper functioning of the aluminum foil lubrication system is vital for cigarette packaging equipment. In summary, stable aluminum foil lubrication in cigarette packaging equipment has a significant impact on packaging quality, requiring the system to operate normally to ensure consistent and aesthetically pleasing packaging.

[0043] Example 1

[0044] This invention provides a lubrication monitoring system for the aluminum foil lubrication device in cigarette packaging equipment, such as... Figure 1 As shown, it includes a sensor monitoring component 1, a sensor amplifier component 2, a data processing controller 3, and an encoder 4;

[0045] The input and output ends of the sensor monitoring component 1 are respectively connected to the oil outlet pipe of the lubrication device of the packaging equipment 5 and the lubrication felt oil pipe of the packaging equipment 5.

[0046] The signal receiving end of the sensor amplifier assembly 2 is connected to the signal of the sensor detection head 5 of the sensor monitoring assembly 1, and the signal output end is connected to the data processing controller.

[0047] The encoder 4 is used to detect the aluminum foil conveying speed information during the operation of the packaging equipment 5;

[0048] The input terminals of the data processing controller 3 are connected to the sensor amplifier assembly 2 and the encoder 4, respectively, and the output terminal is connected to the signal input terminal of the packaging equipment 5. After processing the received aluminum foil lubricant droplet signal and aluminum foil conveying speed information, the obtained aluminum foil lubricant flow information is transmitted to the packaging equipment 5.

[0049] Specifically, such as Figure 2 As shown, the sensor monitoring assembly includes an upper connector 11, a base 12, a burette 13, a sensor detection head 15, a detection tube 6, and a lower connector 17.

[0050] The detection tube 16 and the sensor detection head 15 are fixed in the base 12. The detection tube 16 is perpendicular to the ground, and the sensor detection head 15 is perpendicular to the detection tube 16. The detection tube 16 is hollow, and an upper connector 11 and a lower connector 17 are respectively provided at both ends.

[0051] One end of the upper connector 11 is connected to the oil outlet pipe of the lubrication device of the packaging equipment 5, and the other end is connected to the detection tube 16 through the burette 13. The burette 13 is connected to the central axial position of the upper connector 11, and the lower end of the liquid outlet is higher than the sensor detection head 15 to ensure that the lubricating liquid droplets 14 are of uniform size and pass through the sensor detection head 15.

[0052] One end of the lower connector 17 is connected to the detection tube, and the other end is connected to the lubricating felt oil pipe of the packaging equipment.

[0053] In this embodiment, the sensor detection head 15 is a photosensitive sensor, mirror-distributed on both sides of the detection tube 16, used to monitor the photosensitive signal of the aluminum foil lubricating droplet 14 and send the photosensitive signal to the sensor amplifier assembly 2. Specifically, the sensor detection head 15 includes a set of through-beam optical fibers, such as through-beam focused infrared optical fibers. The through-beam optical fibers include a transmitter and a receiver arranged opposite each other, and are distributed on both sides of the detection tube 16 in a mirror-distributed manner, which can reduce external interference. It should be noted that the present invention does not specifically limit the type and distribution of the through-beam optical fibers.

[0054] The sensor amplifier assembly 2 described in this embodiment includes sensor amplifiers connected to the through-beam optical fiber. Each sensor amplifier is used to adjust the light sensitivity based on the light-sensing signal detected by its corresponding through-beam optical fiber. In this way, its trigger value can be adjusted individually.

[0055] In some specific embodiments, the data processing controller 3 may be a microcontroller and its peripheral conversion circuit, an IPC small industrial computer, etc. The present invention does not specifically limit the type and model of the data processing controller 3.

[0056] In this embodiment, the data processing controller 3 includes a setting module for setting several detection items and corresponding detection ranges for each detection item. Specifically, the detection items include at least one of the following: whether the aluminum foil lubrication is normal, whether the flow rate of the aluminum foil lubricant is within a preset range, and whether the aluminum foil flow rate is within the range required by the current aluminum foil conveying speed. This allows for diverse detection of the aluminum foil lubricant flow rate, improving product quality.

[0057] During operation, after the sensor detection head 15 collects the light source signal, it is converted into an electrical signal by the sensor amplifier assembly 2. The data processing controller 3 then converts the received electrical signal into a digital image signal. The data processing controller 3 receives the speed signal from the encoder 4. Figure 3 The image shows the information obtained by combining the digital image signal with the speed signal from encoder 4. The horizontal axis represents the detected aluminum foil conveying speed, and the vertical axis represents the flow rate of the aluminum foil lubricant. The flow rate is obtained by the optical signal of the aluminum foil lubricant collected by sensor head 15 within the detection tube. The thick line in the middle represents the flow rate of the aluminum foil lubricant on the coordinate axis. Figure 3 The two thin lines represent the allowable offset, or preset range, set by the setting module of the data processing controller 3. Based on the positional relationship between the curve at its left and right ends and the horizontal axis, it can be determined whether the aluminum foil lubricant flow rate is stable; based on the slope of the curve at its left and right ends, it can be determined whether the aluminum foil lubricant flow rate is within the preset range.

[0058] The lubrication monitoring system for aluminum foil lubrication devices provided by this invention includes a sensor detection head 15 for detecting the light-sensitive signal of the aluminum foil lubricant in the detection tube 16; a sensor amplifier assembly 2 for adjusting the light-sensitive recognition degree based on the light-sensitive signal and converting the light-sensitive signal into an electrical signal; an encoder 4 for detecting the aluminum foil conveying speed of the packaging equipment 5 during operation; and a data processing controller 3 for converting the electrical signal of the aluminum foil lubricant droplets into a digital signal, and obtaining the flow rate information of the aluminum foil lubricant based on the digital signal and the aluminum foil conveying speed information. This allows the packaging equipment 5 to alarm or stop based on the aluminum foil flow rate information, enabling the detection of aluminum foil lubrication quality, checking for insufficient or excessive lubrication, and improving the folding and forming quality of the aluminum foil.

[0063] Step S2: Adjust the light sensing recognition degree according to the light sensing signal, and convert the light sensing signal into an electrical signal based on the adjusted light sensing recognition degree.
