Description

Technical Field

[0001] The utility model relates to a glue supply mechanism, in particular to a glue supply mechanism for a cigarette making machine. Background Art

[0002] The glue supply system provides a continuous and quantitative amount of glue for the cigarette paper overlap to the gluing device in the rolling process, so that the gluing device can continuously apply a uniform glue line to the cigarette paper to make the overlap bonded.

[0003] The glue supply system mainly consists of a glue storage barrel, a glue barrel sealing cover, a compressed air interface, a glue filter, and a glue pump. During operation, glue is manually added to the glue storage barrel, and the glue barrel sealing cover is tightly closed. Compressed air is injected into the glue storage barrel through the compressed air interface, and the glue is pressed from the glue barrel to the glue filter. After the glue filter filters the solid impurities in the glue, the glue is pressed into the glue pump. The glue pump is driven by the servo motor M216S. According to the glue setting amount in the machine program, the speed of the servo motor M216S is controlled to adjust the glue flow rate, and the glue is evenly and quantitatively delivered to the gluing device.

[0004] The prior art has the following problems: first, when adding glue, the operator needs to pour the glue into the glue storage barrel from the top of the storage barrel. The storage barrel is deep, and the glue will collide with the glue in the barrel when poured in, which will mix air into the glue and form bubbles. These bubbles will flow into the gluing device through the pipeline, causing the gluing of the cigarette rod to be interrupted, resulting in cigarette cracking or slipping.

[0005] Second, the glue storage barrel is installed at a low position, while the glue filter and glue pump are installed at a high position, so the glue cannot naturally flow into the glue filter and enter the glue pump. In order to allow the glue to enter the filter, the glue storage barrel uses a sealed barrel cover, and compressed air is injected to press the glue in the glue storage barrel into the filter. Adding compressed air will accelerate the deterioration of the glue, causing the glue in the glue storage barrel to clump and form glue scale. The glue scale flows to the glue filter together with the glue, causing the glue filter to be frequently blocked. This results in insufficient glue flow, causing the cigarette machine to slip or the cigarette to burst.

[0006] Third, when adding glue to the glue storage barrel, the sealing cover of the glue storage barrel needs to be opened. At this time, the compressed air added is cut off, and the glue storage barrel loses pressure, resulting in insufficient glue flow to the filter, causing the cigarette machine to slip or the cigarette to burst. This series of problems leads to frequent equipment bursting and slipping, and the maintenance frequency remains high. These problems need to be solved urgently. Utility Model Content

[0027] In a specific embodiment, the frame 1 includes an upper support plate 8, a lower support plate 9, a side plate 10 and an electrical installation plate 11. The upper support plate 8, the lower support plate 9 and the four side plates 10 constitute the main structure of the frame 1.

The filter element can be taken out for cleaning or replacement by opening the filter cover 32.

[0034] Furthermore, a glue injection device mounting plate 23 is fixedly provided at the bottom of the upper support plate 8.

The second ultrasonic liquid level sensor 27 is fixed on the top plate of the glue storage barrel 2, and the second ultrasonic liquid level sensor 27 is completely the same as the first ultrasonic liquid level sensor 20, and the two are arranged side by side.

[0035] In the prior art, the measurement of glue quantity is realized by a capacitive glue level detection device. The capacitive glue level detection device is directly placed in the glue barrel. It senses and detects the change of capacitance according to the change of glue liquid level, and converts it into a current signal and sends it to the controller. The controller sends the information to the display screen after program processing, and displays the real-time glue quantity on the display screen. This detection method has the problems of low detection accuracy, the capacitive glue level detection device is easily corroded by glue, and the capacitive glue level detection device is huge in size and compact in installation position. This embodiment adopts a first ultrasonic liquid level sensor 20 and a second ultrasonic liquid level sensor 27. The ultrasonic liquid level sensor has high detection accuracy and detection volume. The size is small and the installation is flexible. At the same time, there is no contact with the liquid surface, which avoids the contamination and corrosion of the sensor by the glue. The capacitive detection adopted by the existing equipment sends the electrical signal to the controller as a current signal with a range of 4-20MA, which corresponds to full glue and empty glue respectively. The ultrasonic level sensor in this embodiment also uses 4-20MA current ultrasonic detection. Because of the detection principle, the range of the capacitive detection device of the original equipment and the change of the glue level are inversely proportional. When the ultrasonic detection with a range of 4-20MA is selected, it is necessary to reverse through the signal converter. After the reversed detection signal is sent to the PLC programmable controller, the glue level can be accurately displayed. At the same time, the detection accuracy of the signal converter can be adjusted, so as to facilitate the adjustment of the control accuracy of the output signal, so that the first ultrasonic level sensor 20 and the second ultrasonic level sensor 27 are more accurate and reliable.

[0036] The working principle of the utility model is as follows: during daily work, the staff sends control instructions through the intelligent terminal, the electrical control unit 21 receives the control instructions through the communication module and sends them to the PLC programmable controller, the PLC programmable controller controls the glue pump 4 to work, and the glue pump 4 pressurizes the glue and sends it to the gluing device. When the utility model is working, the first ultrasonic liquid level sensor 20 collects the glue level in real time, and sends the collected information to the PLC programmable controller after conversion by the signal converter. After program processing, the PLC programmable controller displays the liquid level information through the intelligent terminal, and the staff can know the remaining glue. When the glue is insufficient, the high-pressure gas connector 25 is connected to the glue barrel on the glue adding trolley through the air pipe, and the glue outlet of the glue barrel on the glue adding trolley is connected to the quick connector 26 through the hose. The start switch 29 is pressed, and the PLC programmable controller controls the solenoid valve to open, and the working indicator light 30 is lit. The high-pressure gas enters the glue barrel on the glue adding trolley, and the glue enters the first soft connecting pipe 5 through the quick connector 26 and the connecting pipe, and then enters the glue sealing bag 7 through the valve 18. The glue added in this way will not be mixed with air, ensuring that the overlapping glue coating will not be interrupted, solving the problem of cigarette bursting or running. The second ultrasonic liquid level sensor 27 detects the liquid level of the glue in real time. When the glue is full, the PLC programmable controller controls the solenoid valve to close, and the working indicator light 30 goes out, and the glue adding is completed.

[0037] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
