Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production, in particular to a device for calibrating the gap between a rolling wheel and a laser punching wheel. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] The online cigarette punching method used in cigarette filter ventilation technology is one of the technologies to achieve tar reduction. After punching, tiny holes are formed in the filter, which dilutes the smoke and reduces the tar content during cigarette smoking. After the cigarettes are rolled into double-length filter cigarettes, they are rolled between the rolling wheel and the laser punching wheel, and the cigarettes rotate one circle to facilitate punching around the filter end. The laser output head is installed above the online laser punching drum on the front of the cigarette assembling machine. Its function is to transmit the laser beam sent by the laser to the double-length cigarette filter to complete the online punching of the cigarettes. Under the action of the two relatively rotating drums, the cigarettes only rotate and do not move, so the uniformity of the punching spacing of the cigarettes can be guaranteed. At present, the calibration of the gap between the rolling wheel and the laser punching wheel, such as Figure 1-Figure 2 As shown, it is necessary to first loosen the two fastening bolts 5 on the rolling wheel device 1, and place a measuring rod 3 with a diameter of 5.1 mm between the rolling wheel 2 and the laser punching wheel 4 (slim cigarettes have a small diameter, and the cigarette rolling process requires higher accuracy of equipment parameters than conventional cigarettes, so the present invention takes slim cigarettes with a diameter of 5.4 mm as an example). With the laser punching wheel 4 as a reference, move the rolling wheel device 1 to make the rolling wheel 2 rise or fall in order to adjust the gap between the rolling wheel 2 and the laser punching wheel 4, tighten the fastening bolts, and after the initial adjustment, start the machine and perform recalibration as needed.

[0004] The following problems exist in the actual calibration method: First, the calibration operation is inconvenient. Due to the use of a cylindrical measuring rod, the roller and laser punching wheel are in line contact with the measuring rod. It is very difficult to make the centers of the roller, measuring rod, and laser punching wheel located on the line connecting the centers of the roller and laser punching wheels by visual inspection alone, and the measuring rod is very easy to slip. Second, the roller is divided into front and rear rollers, and the light on the inside is darker, so the measuring rod is skewed during calibration. In order to ensure the calibration accuracy as much as possible, when calibrating the gap, it takes a long time because the measuring rod needs to be repeatedly calibrated. A skilled maintenance worker needs 30 minutes to calibrate the roller, which affects the operating efficiency of the equipment. In addition, inaccurate gap position calibration will affect the quality of cigarette punching, and will also lead to the consumption of auxiliary materials and increase the labor intensity of employees. Utility Model Content

[0027] Example 1

[0028] This embodiment provides a device for calibrating the gap between the rolling wheel and the laser drilling wheel. Figure 3 As shown, it includes a calibration plate 6, one end of which is provided with a hand-held mechanism, the upper plate surface of the calibration plate 6 is provided with a first concave arc surface 7 matching the rolling wheel 2, and the lower plate surface of the calibration plate 6 is provided with a second concave arc surface 8 matching the laser punching wheel 4. When in use, the first concave arc surface 7 is fitted with the front and rear rolling wheels, and the second concave arc surface 8 is fitted with the laser punching wheel 4, thereby realizing the gap calibration between the rolling wheel 2 and the laser punching wheel 4.

[0029] In this embodiment, the calibration plate 6 is a rectangular plate, and the length of the calibration plate 6 is greater than the distance between the end faces of the front and rear roller wheels that are away from each other. With this setting, there is no need to precisely control the length of the calibration plate 6 extending into the gap between the roller wheel 2 and the laser punching wheel 4, which makes it convenient for the calibration plate 6 to cooperate with the front and rear roller wheels and the laser punching wheel 4, thereby facilitating the calibration operation.

[0030] A first concave arc surface 7 is provided in the middle position of the upper plate surface of the calibration plate 6. The first concave arc surface 7 matches the rolling wheel 2 and can be in surface contact with the wheel surface of the rolling wheel 2, replacing the top line of the measuring rod 3 to contact the rolling wheel 2. Along the length direction of the calibration plate 6, the first concave arc surface 7 is provided throughout the length, that is, one end of the first concave arc surface 7 extends to one side end surface of the calibration plate 6, and the other end extends to the other side end surface of the calibration plate 6.

[0031] A second concave arc surface 8 is provided at the middle position of the lower plate surface of the calibration plate 6. The second concave arc surface 8 matches the laser punching wheel 4 and can be in surface contact with the wheel surface of the laser punching wheel 4, replacing the lower top line of the measuring rod 3 to contact the laser punching wheel 4. Along the length direction of the calibration plate 6, the second concave arc surface 8 is provided throughout the length, that is, one end of the second concave arc surface 8 extends to one side end surface of the calibration plate 6, and the other end extends to the other side end surface of the calibration plate 6.

[0032] The distance between the lowest points of the first inward concave arc surface 7 and the second inward concave arc surface 8 is equal to the set target gap. In this embodiment, the distance between the lowest points of the first inward concave arc surface 7 and the second inward concave arc surface 8 is 5.1 mm.

[0033] The hand-held mechanism includes a hand-held rod 9, which is detachably fixed to the center position of the end face of one side of the calibration plate 6. Specifically, the end of the hand-held rod 9 used to connect to the calibration plate 6 is provided with an external thread structure, and correspondingly, the center position of the end face of the calibration plate 6 used to connect to the hand-held rod 9 is provided with an internal thread hole matching the external thread structure. The hand-held rod 9 is threadedly fixed to the calibration plate 6 through the external thread structure and the internal thread hole.

[0034] One end of the hand-held rod 9 is detachably fixedly connected to the calibration plate 6 by a thread, and the other end is provided with a circular hanging ring 10, which facilitates the carrying and storage of the entire calibration device.

[0035] Furthermore, the diameter of the hand-held rod 9 is smaller than the set target gap, that is, the diameter of the hand-held rod 9 is smaller than 5.1 mm, to prevent the hand-held rod 9 from affecting the calibration of the gap between the rolling wheel 2 and the laser punching wheel 4 when it is extended between the rolling wheel 2 and the laser punching wheel 4.

[0036] The method of using the calibration device of this embodiment is as follows:

[0037] like Figure 4-Figure 5 As shown, the turning wheel rotates the laser punching wheel 4 into the rolling position, loosens the two fastening bolts 5 on the rolling wheel device 1, and then puts it into the calibration device, puts the calibration plate 6 into the area between the rolling wheel 2 and the laser punching wheel 4, so that the second concave arc surface 8 is in contact with the wheel surface of the laser punching wheel 4, and then the rolling wheel 2 is lowered into the calibration position, and the calibration device is adjusted so that the wheel surface of the rolling wheel 2 is in contact with the first concave arc surface 7, and then tightens the two fastening bolts 5 on the rolling wheel device 1 to complete the calibration of the gap between the rolling wheel 2 and the laser punching wheel 4. After the calibration is completed, the entire calibration device can be taken out.

[0038] When using the calibration device of this embodiment, the gap calibration is completed after the rolling wheel 2 contacts the first concave arc surface 7 and the laser punching wheel 4 contacts the second concave arc surface 8. Surface contact is used instead of line contact for calibration, and the calibration plate 6 is not easy to fall off. At the same time, the calibration plate 6 contacts the front and rear rolling wheels at the same time, and will not be skewed. This solves the problem of repeatedly confirming the calibration points of the rolling wheel and the measuring rod by holding a measuring rod in hand. The gap between the rolling wheel 2 and the laser punching wheel 4 can be quickly calibrated, ensuring the accuracy of the calibration, greatly reducing the difficulty of calibration, and avoiding the problem of the measuring rod easily falling, thereby improving the efficiency of calibration.

[0039] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
