Description

Technical Field

[0001] The present invention belongs to the technical field of cigarette production, and more particularly, relates to a cigarette microwave channel cleaning device and a cleaning method thereof. Background Art

[0002] The microwave cigarette weight scanner in a cigarette making machine is a critical component for measuring and controlling tobacco rod quality during production. The microwave channel serves as a bridge for supporting and transporting tobacco rods. During production, tobacco rods often carry paper dust and residual glue, which deposit on the microwave channel. If not cleaned promptly, this can hinder the movement of the tobacco rods, causing minor problems such as rod slippage. In more serious cases, the tobacco rods may become wrinkled, scratched, contaminated, or torn. If these are released into the market, they can cause serious quality issues. If cleaning is performed, the tobacco rods will be difficult to completely clean within the inner wall of the microwave channel, affecting the operational stability of the equipment. Summary of the Invention

[0003] The purpose of the present invention is to address the above shortcomings and provide a cigarette microwave channel cleaning device and a cleaning method thereof, which solves the technical problem of difficulty in cleaning the microwave channel after it is contaminated, reduces the probability of dust and residual glue remaining in the channel, reduces the rate of cigarette rod escape, and improves the operating efficiency of the equipment.

[0004] To achieve the above object, the present invention is implemented through the following technical solutions:

[0005] In a first aspect, the present invention provides a cigarette microwave passage cleaning device, comprising a fixed cigarette guide rod and a movable cigarette guide rod that are combined to form a cleaning passage, wherein the outlet ends of the fixed cigarette guide rod and the movable cigarette guide rod are connected to an adjustment sleeve, and the inlet ends are connected to a cutter cleaning mechanism; the cutter cleaning mechanism includes a cutting blade and a cylinder, and the cylinder drives the extension and retraction of the cutting blade and the opening and closing of the movable cigarette guide rod; the cutter cleaning mechanism is mounted on a mounting base via a body connector, and the mounting base is fixed to a microwave detection device of a cigarette making machine; the adjustment sleeve and the mounting base are both connected to a compressed air source that can communicate with the cleaning passage;

[0006] It also includes a controller, wherein the signal input end of the controller is connected to the cigarette making machine and the sensor of the cylinder, and the signal output end is connected to the compressed air source and the control valve of the cylinder.

[0007] Specifically, the controller's signal input can collect signals such as the cigarette maker's RCP speed signal, manual / automatic mode signal, cutter cover opening signal, strip running signal, first soldering iron lowering signal, strip breaking signal, manual cleaning button signal, cylinder extension / retraction signal, and air pressure analog signal. These signals are collected from the cigarette maker itself. The cylinder extension / retraction signal is provided by two Hall sensors attached to the cylinder, and the air pressure analog signal is provided by a control valve connected to the compressed air source and the cylinder.

[0008] The microwave detection device is a device on the cigarette making machine that detects the real-time weight of the cigarette rods. The cigarette microwave channel cleaning device of the present invention is installed at the rear end of the microwave detection device. On the one hand, it plays a role in supporting and stabilizing the operation of the cigarette rods. On the other hand, it can cleanly remove cigarette paper dust and glue brought into the cigarette rods through the microwave, as well as some cigarette ends that affect detection.

[0009] Furthermore, the adjustment sleeve includes a fixed adjustment sleeve seat and a movable adjustment sleeve seat. The fixed adjustment sleeve seat is fixedly connected to the fixed tobacco guide rod, while the movable adjustment sleeve seat is fixedly connected to the movable tobacco guide rod and opens and closes with the movable tobacco guide rod. The components are slotted and secured with adjustment screws. Fine-tuning can be achieved by changing the position of the adjustment screws to radially move the movable adjustment sleeve seat and fixed adjustment sleeve seat, ensuring smooth entry of the tobacco rod into the channel.

[0010] Furthermore, both the fixed and movable adjustment sleeve bases are provided with obliquely drilled holes extending therethrough. The outer ends of these holes are provided with a spiral air pipe connector hole for connecting to a compressed air source. The inclination of these obliquely drilled holes aligns the direction of compressed air entry with the flow of the tobacco rod. This design creates a negative pressure within the cleaning channel cavity when compressed air enters from the end of the adjustment sleeve, removing any remaining dust within the sealed cavity.

[0011] Furthermore, the interior of the cleaning channel formed by the fixed smoke guide rod and the movable smoke guide rod adopts a funnel-shaped design, and the diameter of the inlet end is larger than the diameter of the outlet end.

[0012] Furthermore, the diameter of the inlet end of the cleaning channel is 1.3 times the diameter of the cigarette, and the diameter of the outlet end is 1.1 times the diameter of the cigarette. The diameter changes from large to small, which facilitates the cigarette rod to enter the cleaning device.

[0013] Furthermore, the cutter cleaning mechanism also includes a cylinder connecting rod, a cylinder slider and a cutter magazine. The cylinder slider is connected to the cylinder connecting rod. The cylinder piston in the cylinder drives the cylinder slider and the cylinder connecting rod to move up and down. The other end of the cylinder connecting rod is connected to the movable smoke guide rod and the cutter blade. The cutter blade can adopt an inner hole type cutter blade and be placed in the cutter magazine.

[0014] Furthermore, the cigarette microwave channel cleaning device further comprises a manual cleaning button connected to the signal input terminal of the controller. The control signal points of the manual mode and the automatic mode of the present invention are connected in parallel, and the manual mode has a higher priority than the automatic mode.

[0015] In a second aspect, the present invention further provides a cleaning method for the cigarette microwave channel cleaning device according to the first aspect. When the cigarette making machine enters automatic mode, the method comprises:

[0016] In response to the normal operation signal of the cigarette making machine, the compressed air source connected to the mounting seat is turned on to perform air blowing and cleaning, and then the cylinder is controlled to extend, driving the movable cigarette guide rod to close, and then the cutting blade is returned to the cutting blade chamber;

[0017] In response to the cylinder extended to the end signal, the compressed air source connected to the adjusting sleeve is turned on to blow air to clean the cleaning channel at a preset first air pressure value P1;

[0018] In response to the cigarette making machine's signal, the cigarette rod is delayed for t to enter the cleaning channel, and then the pressure of the compressed air entering the regulating sleeve end is adjusted to a preset second pressure value P2 to keep the cigarette rod running stably;

[0019] The preset first air pressure value P1 is greater than the preset second air pressure value P2. The preset second air pressure value P2 can be used to maintain stable operation of the tobacco rod, and the preset first air pressure value P1 is used to increase the cleaning force and make the cleaning more thorough.

[0020] In the above steps, the compressed air source connected to the mounting base can be used to perform air blowing cleaning, and the number of cleaning times can be set according to cleaning needs. When the counter measures that the required number of cleaning times is reached, the next step is entered.

[0021] In the above steps, the delay t is to allow the negative pressure in the cleaning channel cavity to complete the task of receiving and guiding the cigarette rod; at the same time, the pulling of the negative pressure eliminates the slight vibration of the cigarette rod during operation, reducing the probability of dust and residual glue remaining in the channel due to vibration.

[0022] Furthermore, in the automatic mode of the cigarette making machine, the method further includes:

[0023] When the cigarette making machine stops due to strip running:

[0024] In response to the cigarette machine's running signal, the control cylinder drives the cutting blade out of the cutting chamber, cuts the tobacco rods in the channel, and drives the movable cigarette guide rod to open upwards;

[0025] In response to the cylinder retraction signal, the compressed air source connected to the mounting base is turned on to perform air cleaning, blowing off the cigarette rods blocked on the fixed cigarette guide rod. This process can be repeated as many times as needed.

[0026] In the above steps, in the automatic cleaning state, there is no need to open the cigarette making machine cutter head protective cover. When the controller cannot receive the cigarette making machine speed signal RCP pulse, it is confirmed that the cigarette making machine has completely stopped running and the control cylinder works directly.

[0027] Furthermore, when a malfunction or difficulty in cleaning the cigarette rod occurs, the manual operation mode of the cigarette making machine is enabled. In manual operation mode, the cleaning method includes:

[0028] Open the cigarette making machine cutter head protective cover;

[0029] When the controller receives the signal to open the cutter head guard of the cigarette making machine, it controls the cylinder to drive the cutter blade out of the cutter chamber, cuts the tobacco rods in the channel, and drives the movable tobacco guide rod to open upwards;

[0030] The operator checks the separated channels;

[0031] Press the manual cleaning button, the controller controls the compressed air source connected to the mounting base to blow and clean, and then controls the cylinder to extend, driving the movable smoke guide rod to close, and then the cutting blade returns to the cutting chamber;

[0032] When the controller receives the signal that the cylinder has extended to the full position, it opens the compressed air source connected to the adjusting sleeve and blows air to clean the cleaning channel with the preset first air pressure value P1. At the same time, the operator cleans the channel with a brush, and the airflow helps the accumulated glue and dust to be discharged from the channel through the adjusting sleeve.

[0033] In the above steps, the cigarette making machine cutter head protective cover opening signal is a safety signal, which means that the cigarette making machine is in a shutdown state.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] The cigarette microwave channel cleaning device and method described in the present invention solve the technical problem of difficult cleaning of contaminated microwave channels, reduce the probability of dust and residual glue remaining in the channel, and achieve automatic and assisted cleaning of the microwave channel. This reduces the probability of cigarette rods slipping, enhances the stability of cigarette rod conveying, ensures the quality of cigarette rods during conveying, reduces labor intensity, and has excellent application prospects.

For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0043] Example 1

[0044] This embodiment provides a cigarette microwave channel cleaning device, such as Figure 1 and Figure 2 As shown, the device comprises a fixed cigarette guide rod 12 and a movable cigarette guide rod 13, which together form a cleaning channel 21. The outlet ends of the fixed and movable cigarette guide rods 12 and 13 are connected to an adjustment sleeve, while their inlet ends are connected to a cutter cleaning mechanism 16. The cutter cleaning mechanism 16 is mounted on a mounting base 11 via a body connector. The mounting base 11 is fixed to the cigarette making machine's microwave detection device. By selecting different mounting bases 11, the device can adapt to the circumference of different cigarette brands and can be installed on any cigarette making machine, ensuring immediate use and high adaptability.

[0045] In this embodiment, the cutter cleaning mechanism 16 includes a cylinder connecting rod 17, a cylinder slider 18, a cylinder, an inner hole type cutting blade 19, and a cutter magazine 110. The cylinder adopts a double-acting cylinder. The cylinder piston in the cylinder drives the cylinder slider 18 to move up and down. The cylinder slider 18 is connected to the cylinder connecting rod 17, and the other end of the connecting rod is connected to the movable smoke guide rod 13 and the cutting blade 19. The cutting blade 19 is built into the cutter magazine 110. The five work together to complete the cutting of the tobacco rod when the microwave channel is blocked and the opening, closing and locking of the channel.

[0046] In this embodiment, the interior of the cleaning channel 21 adopts a funnel-shaped design. The diameter of the inlet end of the cleaning channel 21 is 1.3 times the diameter of the cigarette, and the diameter of the outlet end is 1.1 times the diameter of the cigarette. The adjustment sleeve includes an adjustment sleeve fixed seat 14 and an adjustment sleeve movable seat 15. The adjustment sleeve fixed seat 14 and the adjustment sleeve movable seat 15 are respectively fixed to the fixed cigarette guide rod 12 and the movable cigarette guide rod 13. The parts are slotted and tightened with adjustment screws. When fine-tuning, the position of the adjustment screw can be changed to cause the adjustment sleeve movable seat 15 and the adjustment sleeve fixed seat 14 to move radially, ensuring that the cigarette rod can enter the channel smoothly.

[0047] In this embodiment, the mounting base 11 is provided with an air vent for connecting the air pipe of the compressed air source. A 30-degree 2MM oblique drilled hole 22 is respectively passed through the bottom of the adjusting sleeve fixed base 14 and the top of the adjusting sleeve movable base 15. A spiral air pipe joint hole 23 is provided above the oblique drilled hole 22 for connecting the air pipe joint of the compressed air source. The compressed air sources connected at both ends are connected to the cleaning channel 21. The inclination direction of the oblique drilled hole 22 makes the direction in which the compressed air enters the same as the flow direction of the tobacco rod. Through the compressed air, the inside of the cleaning channel 21 becomes thinner due to the inlet airflow, which accelerates the gas flow rate and forms a negative pressure vacuum. The vacuum plays a role in stabilizing the tobacco rod and cleaning dust and glue during the operation of the tobacco rod.

[0048] In this embodiment, the cigarette microwave channel cleaning device further includes a controller (not shown). The controller's signal input is connected to sensors in the cigarette making machine and the cylinder, and its signal output is connected to a compressed air source and a control valve for the cylinder. The compressed air source's air pipe is connected to an automatic cleaning valve, which is a proportional valve.

[0049] Specifically, the controller's signal input can collect signals from the cigarette maker's RCP speed, manual and automatic mode, cutter cover opening, strip running, first soldering iron lowering, strip beating, manual cleaning button, cylinder extension and retraction, and air pressure simulation. These signals are collected from the cigarette maker itself. The cylinder extension and retraction signals are provided by two Hall sensors attached to the cylinder, and the air pressure simulation signal is provided by an automatic cleaning valve connected to a compressed air source. The controller's signal output controls the cylinder's control valve and the automatic cleaning valve of the compressed air source to open and close the cylinder and clean the compressed air. Pressure regulation of the automatic cleaning valve is achieved through a BCD code compilation pattern. The cleaning count status is processed internally by the program and displayed via the HMI.

[0050] In this embodiment, the cigarette microwave channel cleaning device further includes a manual cleaning button connected to a signal input terminal of the controller. The control signal points of the manual mode and the automatic mode are connected in parallel, and the manual mode has a higher priority than the automatic mode.

[0051] Example 2

[0052] This embodiment provides a cleaning method for the cigarette microwave channel cleaning device described in Example 1, and the process is as follows: Figure 3 As shown, the specific steps include:

[0053] When the cigarette making machine enters automatic mode:

[0054] When the controller receives a downward signal from the first soldering iron (i.e., a normal operation signal of the cigarette making machine), the compressed air on the mounting base 11 is turned on for 1 second of blowing cleaning. Then, the cylinder extends downward to first close the movable cigarette guide rod 13 and then drives the cutting blade 19 back to the cutting blade chamber 110. The number of cleaning times in this process is set to 3. When the counter measures 3 times, the process proceeds to the next step.

[0055] When the controller receives the signal that the cylinder has been extended to the full position, it turns on the compressed air source connected to the regulating sleeve end to clean the cleaning channel 21 with 4mbar compressed air, so that the cavity of the cleaning channel 21 forms a negative pressure and removes the residual dust in the sealed cavity;

[0056] When the controller receives the signal from the cigarette making machine to make cigarette rods, it delays for 4 seconds so that the negative pressure in the cavity of the cleaning channel 21 completes the task of receiving and guiding the cigarette rods. The pull of the negative pressure eliminates the slight vibration of the cigarette rods during operation, and reduces the probability of dust and residual glue remaining in the channel due to vibration. After 4 seconds, the controller controls the proportional valve to reduce the pressure of the compressed air at the end of the regulating sleeve to 2mbar to maintain stable operation of the cigarette rods.

[0057] When the cigarette making machine stops due to "strip running" caused by blockage:

[0058] When the controller receives the cigarette machine's running signal (there is no need to open the cutter head protective cover. In the automatic cleaning state, when the controller cannot receive the cigarette machine speed signal RCP pulse, it is confirmed that the cigarette machine has completely stopped running) the control cylinder is directly operated to drive the cutting blade 19 out of the cutting chamber 110 to cut the tobacco rods in the channel and drive the movable cigarette guide rod 13 to open upward;

[0059] When the controller receives the cylinder retracted signal, it opens the compressed air source connected to the mounting base to blow and clean for 5 seconds to blow off the cigarette rods blocked on the fixed cigarette guide rod 12. Repeat the action 3 times to complete the cleaning.

[0060] When a malfunction or difficulty in cleaning the cigarette rod occurs, activate the manual operation mode of the cigarette making machine. In manual operation mode, the cleaning methods include:

[0061] Open the cigarette making machine cutter head protective cover;

[0062] When the controller receives the signal to open the cutter head guard of the cigarette making machine, it controls the cylinder to drive the cutting blade 19 out of the cutting chamber 110 to cut the tobacco rods in the channel and drive the movable tobacco guide rod 13 to open upwards;

[0063] At this point, the operator can view the separated channels;

[0064] Press the manual cleaning button, the controller controls the compressed air source connected to the mounting base 11 to perform 1S of air blowing cleaning, and then controls the cylinder to extend, driving the movable smoke guide rod 13 to close, and then the cutting blade 19 returns to the cutting chamber 110;

[0065] When the controller receives the signal that the cylinder has extended to the full position, it opens the compressed air source connected to the adjusting sleeve and blows 4 mbar compressed air to clean the cleaning channel 21. At the same time, the operator cleans the cleaning channel 21 with a brush, and the airflow helps the accumulated glue and dust to be discharged from the cleaning channel 21 through the adjusting sleeve.

[0066] While various embodiments of the present invention have been described above, the foregoing description is intended to be illustrative and non-exhaustive, and is not intended to be limiting of the disclosed embodiments. Numerous modifications and variations will be apparent to those skilled in the art without departing from the scope and technical principles of the described embodiments, and such modifications and variations should be considered within the scope of the present invention.
