Description

Technical Field

[0001] The utility model relates to the technical field of tipping paper production equipment, in particular to a tipping paper initial section cutting and adjusting device for a laser punching system. Background Art

[0002] Reducing the tar content in cigarettes is of great significance to improving smoke quality and reducing the negative impact on the smoking population; cigarette manufacturers in various countries have invested a lot of manpower, material resources and huge amounts of money to conduct extensive and in-depth research on technologies to reduce the tar content of cigarettes, mainly targeting reducing the tar and carbon monoxide content of cigarettes. According to research, the most direct method is ventilation dilution technology, that is, punching holes on the surface of specific parts of the tipping paper to increase the amount of air inhaled, so as to dilute the smoke and reduce its concentration. Existing tipping paper punching technologies mainly include mechanical punching, electric spark punching, electrostatic punching and laser punching. Among them, laser punching has the advantages of regular shape, controllable air permeability change, and fast production speed, and is the most widely used.

[0003] When laser punching is performed, the tipping paper is unwound first, and the paper enters the laser punching area through the tension adjustment mechanism. After the punching is completed, the reeling mechanism reels it. However, there is a certain distance between the unwinding, punching and rewinding stations, especially the rewinding station needs to first glue or fix the tipping paper on the reel roller, which can drive the tipping paper to move in the entire equipment for punching. Therefore, according to the normal reel paper reeling procedure, the initial section of tipping paper on the reel roller is not punched. According to the process requirements of cigarette forming, the tipping paper involved in cigarette forming must be punched as a whole. The tipping paper without holes will result in unqualified products after cigarette forming.

[0004] According to the traditional production process, in order to remove the unpunched part of the tipping paper wound on the innermost side of the winding roller, the processed tipping paper reel needs to be rewound, but this operation will greatly increase the production time and affect the production efficiency. To this end, some corresponding solutions have emerged. For example, the patent documents CN102167238B and CN203461583U both disclose devices that can cut off the unpunched tipping paper generated by winding and unwinding during the punching stage, which to a certain extent solves the problem that the starting end of the tipping paper laser punching equipment is punched, and improves the production efficiency, but there are shortcomings such as complex mechanism structure and low success rate of cutting and second winding. Summary of the invention

[0005] In order to solve the above problems, the utility model provides a tipping paper initial section cutting and adjusting device for a laser punching system, which can cut off and remove the tipping paper without punching at the end, and realize the second winding of the tipping paper by electrostatic adsorption.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a tipping paper initial section cutting and adjusting device for a laser punching system, characterized in that it includes a tipping paper unwinding mechanism, a laser punching mechanism 5, a first winding mechanism, and also includes a second winding mechanism;

[0007] The unwinding mechanism includes an unwinding roller 1 and a plurality of guide rollers 2; firstly, a tipping paper reel metering device is arranged on the upper right side of the unwinding roller 1, and a metering probe 3 is arranged on the metering device, which is downwardly aligned with a specific position of the tipping paper reel, and also includes a controller 4; the tipping paper reel is mounted on the unwinding roller 1, and the metering probe 3 locates the unwinding starting end of the tipping paper to calculate the unwinding length, and stores the information in the controller 4 connected to the metering probe 3;

[0008] The second winding mechanism is arranged behind the laser punching mechanism 5, and includes a second winding roller 6 and a pneumatic flattening roller 7; the pneumatic flattening roller 7 is located directly below the second winding roller 6, and the axes of the two are parallel to each other. The pneumatic flattening roller 7 is connected and driven by a cylinder, and can rotate and hover arbitrarily within the second quadrant of 90°-180°, so as to keep the pressure on the roller surface of the second winding roller 6;

[0009] Above the second winding roller 6, a first winding mechanism is provided, which includes a vertical sliding track 8, a sliding block 9 clamped on the track, a first winding roller 10 in the horizontal direction is fixedly installed at the lower end of the sliding block 9, the first winding roller 10 is connected to the telescopic shaft of the cylinder fixed above the sliding track 8, and the pneumatic switch of the cylinder is connected to the controller 4; the telescopic shaft of the cylinder extends downward, driving the first winding roller 10 to press down, and its roller surface contacts the second winding roller 6; on the right side of the cylinder on the vertical sliding track 8, a secondary trigger device 11 of the cylinder is provided, which is connected to a telescopic rod, and a trigger switch is provided at the lower end of the telescopic rod, the trigger switch is connected to the controller 4, and the signal of the trigger switch is transmitted to the controller 4, and the pneumatic switch of the cylinder is controlled by the controller 4;

[0010] On the right side of the sliding track 8, an automatic roll changing device is provided; the automatic roll changing device is arranged at the upper right of the second winding roller 6, and includes an electrostatic application mechanism and a tipping paper cutting mechanism; the two are installed on the same rotating bracket 12, and the rotating bracket 12 includes a square mounting groove 13 fixed to the rotating disk; the square mounting groove 13 is sealed on the front side and grooved on the back side, and a telescopic cylinder 14 is arranged in the groove, and the telescopic cylinder 14 pushes the end 15 of the square mounting groove 13 to move; and a pneumatic wind knife 16 is fixed at the upper end of the end 15, and an electrostatic generator 17 is fixed at the lower end of the end 15.

[0011] Preferably, a buffer limit device 18 for the retracted state of the cylinder telescopic shaft is provided on the left side of the vertical sliding track 8. The device is vertically installed on the side of the sliding track 8 as a whole, and a compression spring is provided inside it. An elastic buffer head is provided at the lower end, and the buffer head is opposite to the upper edge of the sliding block 9. When the sliding block 9 is retracted, the cylinder body will be impacted due to inertia. A buffer limit device 18 capable of blocking its upper edge is provided below its retracted limit position, which can reduce the noise of the equipment and extend its service life.

[0012] Preferably, a detection device is provided on the right side of the sliding track 8, the detection device includes a detection probe 19, and is connected to the controller 4, which detects whether holes appear on the tipping paper passing through the laser punching mechanism 5, and transmits real-time information to the controller 4. The controller 4 combines the tipping paper length data given by the metering probe 3 and the information on the appearance of holes in the tipping paper transmitted by the detection probe 19 to determine the time point for changing the roll.

[0013] When the device is working, firstly, the tipping paper reel to be punched is mounted on the unwinding roller 1, and then the end of the tipping paper reel is manually pulled through a plurality of guide rollers 2 in sequence and enters the laser punching mechanism 5, and then it is pulled upward from under the second winding roller 6, and the cylinder on the vertical sliding track 8 is extended to press down the first winding roller 10 installed on the sliding block 9, and the end of the tipping paper is finally attached to the roller surface of the first winding roller 10 at the joint with the roller surface of the second winding roller 6, and the pneumatic flattening roller 7 rotates and presses against the roller surface of the second winding roller 6, and the state at this time is: the real end of the tipping paper is attached to the roller surface of the first winding roller 10, the punching starting point of the tipping paper is located below the laser punching mechanism 5, and the unwinding starting point of the tipping paper is located below the meter probe 3;

[0014] Start the rotating bracket 12, drive the square installation slot 13 toward the second winding roller 6, the telescopic cylinder 14 in the slot extends, the pneumatic wind knife 16 fixed at its end 15 approaches the first winding roller 10, and the electrostatic generator 17 contacts the roller surface of the second winding roller 6;

[0015] Then the motor of the second winding roller 6 is started to drive the tipping paper to run, the laser punching mechanism 5 works normally, and the tipping paper passing through is punched. The tipping paper before the punching starting point is normally rolled up onto the first winding roller 10. During the winding process, the detection probe 19 on the detection device detects the holes on the tipping paper passing through the laser punching mechanism 5 and transmits the real-time information to the controller 4. At the same time, the meter probe 3 monitors the unwinding length, and the controller 4 combines the two information to determine the time point for changing the roll of the tipping paper. When starting to change the roll, the wind knife is started to quickly cut the tipping paper between the first winding roller 10 and the second winding roller 6, and then the cylinder on the vertical sliding track 8 starts the first contraction to turn the first winding roller 10 into the second winding roller 6. The first winding roller 10 is lifted a certain distance to separate from the roller surface of the second winding roller 6, and the rising sliding block 9 hits the contact switch, triggering the second contraction of the cylinder, and lifting the first winding roller 10 as a whole. The lifting distance is much greater than the radius of the tipping paper reel after the second winding roller 6 is completely wound up; while the first winding roller 10 is in motion, the electrostatic generator 17 works to quickly charge the second winding roller 6, and the new tipping paper end with laser punching formed after cutting is adsorbed on the roller surface of the second winding roller 6. Under the continuous rotation of the motor, the punched tipping paper is normally wound on the second winding shaft, thereby achieving the purpose of removing the tipping paper part of the end 15 that has not been punched.

[0016] The reason why the cylinder on the vertical sliding track 8 is provided with a trigger mechanism and performs two contraction actions to complete the lifting of the first winding roller 10 is mainly for safety considerations to avoid the situation where the paper tape flutters and entangles due to the cutting of the tipping paper or the roll is not changed in place. After confirming that the above actions are completed, the winding roller is completely lifted once to eliminate safety hazards.

[0017] Beneficial effects: In order to solve the problem that the laser punching equipment for tipping paper cannot remove the unpunched ends, the utility model is designed and manufactured from aspects such as laser technology, paper feeding method, automation technology, optical system, etc., which improves the automation degree and equipment precision of the equipment, ensures the quality stability of the tipping paper processed products, improves production efficiency, and can realize automatic roll replacement of tipping paper during the laser punching process of tipping paper without stopping for replacement, which is conducive to efficient assembly line operation of cigarette wrapping and molding equipment.
