Description

Technical Field

[0001] The present application relates to the field of tobacco technology, and in particular to a calibration tool for a starting position of a rolling device of a cigarette laser punching system. Background Art

[0002] In the manufacturing process of cigarettes, in order to reduce the tar content of cigarettes, the current common method is to perform online laser drilling on cigarettes through a laser drilling system. The main working device of the laser drilling system in the cigarette making machine is the rolling device, and its working process is to roll the cigarette around the central axis of the cigarette during the laser drilling period to ensure the punching effect of the cigarette. The rolling device consists of a cigarette wheel and a drum wheel that rotates in the opposite direction. Between these two parts, each double-length cigarette rotates 360°, and the holes are punched during the rotation without relative position change. The first condition to ensure the stability of the ventilation of the cigarettes in the online laser drilling equipment in the cigarette production process is to ensure that the cigarette runs stably during the 360° rotation around the axis between the laser drilling drum wheel and the cigarette wheel. To achieve this goal, the starting position of the cigarette wheel when starting to pull the cigarette must be as accurate and reliable as possible.

[0003] However, the key to adjusting the starting position of cigarettes is to ensure that the center point of the cigarette wheel, the center point of the cigarette, and the center point of the laser perforation drum are in a straight line. At present, technicians use a ruler or other straight objects to visually adjust the starting position of cigarettes, place the two ends of the ruler at the center point of the main shaft end of the cigarette wheel and the center point of the laser perforation drum, and then observe with the naked eye whether the end face of the cigarette is divided into two by the ruler or other straight objects. In this way, it is judged whether the center point of the cigarette wheel, the center point of the cigarette, and the center point of the laser perforation drum form a straight line. However, the end face of the laser perforation drum and the end face of the main shaft of the cigarette wheel are not actually on the same plane, and the two ends of the ruler or other straight objects cannot be accurately placed at the center position of the laser perforation drum and the main shaft of the cigarette wheel, so it is difficult to ensure the technical requirements of the three-point straight line. Adjustment in this way not only cannot guarantee the stability of the operation of the cigarette, but also may cause the center point of the cigarette to deviate greatly, making the position of the focusing head lens in the online laser perforation optical path of the cigarette difficult to adjust. At present, experienced maintenance technicians need 2-3 hours to adjust the focus position, and technicians with average skills may even need to spend a shift to adjust the focus position accurately to ensure accurate and effective online laser punching of cigarettes. After years of use, online laser punching equipment needs to regularly calibrate the laser punching mechanical rolling part or regularly replace mechanical spare parts. Each adjustment requires calibration of the cigarette starting position to ensure that the center point of the cigarette wheel, the center point of the cigarette, and the center point of the laser punching drum are in a straight line. This not only increases the workload of technicians for maintenance, but also cannot guarantee the accuracy of maintenance calibration. Utility Model Content

[0025] The embodiment of the present application provides a calibration tool for the starting position of a rolling device of a cigarette laser punching system. The cigarette laser punching system may include a rolling device and a laser transmitter. The laser transmitter can perform laser punching on cigarettes in the rolling device. Figure 1 , Figure 3 and Figure 4 As shown, the rolling device may include a cigarette wheel 2 and a laser punching drum 1 which is parallel to and spaced from the cigarette wheel 2. The laser punching drum 1 is used to convey cigarettes 8 to be punched. For example, the laser punching drum 1 can adsorb the cigarettes 8 in the cigarette grooves in its circumferential direction by negative pressure adsorption; the cigarette wheel 2 is used to push the cigarettes 8 on the laser punching drum 1 into the gap between the cigarette wheel 2 and the laser punching drum 1 at the starting position, and drive the cigarettes 8 to rotate at the starting position, so as to realize laser punching in the circumference of the cigarettes 8.

[0026] like Figure 2As shown, the calibration tool includes a fixed seat 5, a bracket and a light source 6. The fixed seat 5 is used to fix the calibration tool on the rolling device. For example, a through hole can be opened on the fixed seat 5, and the fixed seat 5 can be fixed on the rolling device by bolts. Without limitation, the fixed seat 5 can also be fixed on the rolling device by a buckle or other structure. Preferably, a magnet can be provided on the fixed seat 5, and the fixed seat 5 is fixed to the part of the rolling device that can be adsorbed by the magnet by magnetic adsorption, so as to facilitate installation and disassembly. In the present application, when calibrating the starting position, the calibration tool can be fixed on the bracket of the cigarette wheel 2 through the fixed seat 5, such as the side of the cigarette wheel bracket. Of course, it can also be fixed on the laser perforated drum bracket, or on other structures of the rolling device, which is not limited in the present application. The bracket is connected to the fixed seat 5, and the bracket is used to support the light source 6 to a position that is convenient for calibrating the starting position. The light source 6 is arranged on the bracket, and the light source 6 can be arranged at the end of the bracket. The light source 6 is arranged to emit visible light. For example, the light 9 emitted by the light source 6 is red or green in color for easy observation. The light 9 emitted by the light source 6 is vertically irradiated on the plane to form a bright area in the shape of a straight line. In this embodiment, this can be achieved by setting a straight slit outside the light-emitting part of the light source 6, or setting the light-emitting part of the light source 6 into a straight line to achieve the above function. Preferably, the light source 6 can be a laser light source 6 to obtain better straightness and facilitate the control of the width of the straight line of the bright area. Of course, the light source 6 can also be a non-laser light source. In some embodiments, the thickness of the light 9 emitted by the light source 6 is adjustable. For example, the thickness of the light 9 can be adjusted by setting a straight slit with adjustable width outside the light-emitting part of the light source 6. When the start-up position is calibrated by the calibration tool, the light 9 emitted by the light source 6 can be coplanar with the axis of the smoke-prying wheel 2 and the axis of the laser-drilling drum 1, and irradiate to the gap between the smoke-prying wheel 2 and the laser-drilling drum 1.

[0027] The embodiment of the present application provides a calibration fixture for the starting position of the rolling device of the laser punching system for cigarettes 8. The light 9 emitted by the light source 6 is vertically irradiated on the plane to form a bright area in the shape of a straight line. When the calibration fixture is used to calibrate the starting position, the calibration fixture can be fixed on the rolling device through the fixing seat 5. The light 9 emitted by the light source 6 can be coplanar with the axis of the cigarette wheel 2 and the axis of the laser punching drum 1, and irradiate the gap between the cigarette wheel 2 and the laser punching drum 1. When a cigarette 8 is placed in this gap, the light 9 can irradiate the end face of the cigarette 8, so that it is easier to adjust the center of the cigarette 8 to the visible light marking line formed by the light source 6, ensuring the technical requirements of the three points of the center point of the cigarette wheel 2, the center point of the cigarette 8, and the center point of the laser punching drum 1 being in a straight line. The embodiment of the present application provides a calibration fixture for the starting position of the rolling device of the laser punching system for cigarettes 8. It can shorten the maintenance and adjustment time, and also improve the adjustment accuracy of the starting position of the cigarette 8, ensuring the accurate calibration of the mechanical parts of the laser punching equipment and stable operation.

[0028] In some embodiments, the bracket includes an extension section 4 and a bending section 3 connected to each other, the extension section 4 is connected to the fixing seat, the light source 6 is arranged at one end of the bending section 3 away from the extension section 4, and the extension section 4 is vertically connected to the bending section 3. In this embodiment, when the calibration tool is fixed on the rolling device, the extension direction of the extension section 4 can be the same as the extension direction of the axis of the cigarette removing wheel 2 and the axis of the laser perforating drum wheel 1, and the bending section 3 can support the light source 6 to between the axis of the cigarette removing wheel 2 and the axis of the laser perforating drum wheel 1, so that the light 9 emitted by the light source 6 is projected on the end faces of the cigarette removing wheel 2 and the laser perforating drum wheel 1.

[0029] In some embodiments, the angle between the plane where the axis of the cigarette wheel 2 and the axis of the laser perforating drum wheel 1 are located and the horizontal plane is α, and the angle formed by the bending section 3 is β, where α+β=180°. In this embodiment, this arrangement can make the part of the bending section 3 where the light source 6 is installed parallel to the plane where the axis of the cigarette wheel 2 and the axis of the laser perforating drum wheel 1 are located, so as to facilitate the assembly of the calibration tooling, for example, the extension direction of the linear slit of the light source 6 can be arranged in a colinear manner with the extension direction of the part of the bending section 3 where the light source is installed. In some embodiments, the part of the bending section 3 away from the extension section 4 is provided with a through groove 7, and the through groove 7 is through from the side surface of the extension section 4 where the light source 6 is provided to the opposite side surface, and the through groove 7 extends on the bending section 3 along the extension direction of the bending section 3. In this embodiment, the through groove 7 can be used as an observation window to observe the positional relationship between the visible light identification line formed by the light source 6 projected onto the rolling device and the cigarette 8 and the center of the cigarette 8, so as to facilitate the calibration operation. Exemplarily, the through groove 7 can be a U-shaped groove.

[0030] In other embodiments, the light source 6 is rotatably disposed on the bracket. In this embodiment, the structure of the bending section 3 is not limited. When calibrating, the light source 6 can be rotated to achieve that the light 9 emitted by the light source 6 is coplanar with the axis of the cigarette removing wheel 2 and the axis of the laser perforating drum 1. In other embodiments, the bending section 3 is rotatably disposed on the extension section 4. In this embodiment, other structures of the bending section 3 are not limited. When calibrating, the bending section 3 can be rotated to drive the light source 6 to move, so that the light 9 emitted by the light source 6 is coplanar with the axis of the cigarette removing wheel 2 and the axis of the laser perforating drum 1.

[0031] In some embodiments, the light 9 emitted by the light source 6 forms a fan shape. In this embodiment, this arrangement can reduce the size of the bracket and the light source 6, making the calibration tool compact and easy to use.

[0032] In some embodiments, when the starting position is calibrated by the calibration tool, the light 9 emitted by the light source 6 can be irradiated to the axial position of the end face of the cigarette removing wheel 2 and the axial position of the end face of the laser perforating drum wheel 1, for example, this can be achieved by reasonably setting the extension length of the bracket or the angle of the light 9 emitted by the light source 6. In this embodiment, this setting method can more conveniently make the light 9 emitted by the light source 6 coplanar with the axis of the cigarette removing wheel 2 and the axis of the laser perforating drum wheel 1. Specifically, when calibrating, the visible light marking line formed by the light 9 emitted by the light source 6 on the rolling device and the cigarette 8 passes through the axial position of the cigarette removing wheel 2 and the axial position of the laser perforating drum wheel 1.

[0033] The embodiment of the present application provides a calibration tool for the starting position of the rolling device of the cigarette laser punching system. When in use, the calibration tool can be adsorbed on the side of the cigarette wheel bracket, and the adsorption position is adjusted so that the light emitted by the light source is projected to the center position of the end face of the laser punching drum wheel and the center position of the main shaft end where the cigarette wheel is located, forming a straight visible light marking line. At this time, the cigarette pulling wheel is adjusted to drive the cigarette on the cigarette pulling wheel to move so that the center point of the end face of the cigarette falls on the visible light marking line, ultimately ensuring the technical requirement that the three points of the cigarette pulling wheel center point, the cigarette branch center point, and the laser punching drum center point are in a straight line.

[0034] The calibration fixture for the starting position of the rolling device of the cigarette laser punching system provided in the embodiment of the present application is compact in design and easy to use, which shortens the maintenance and adjustment time, and also improves the calibration accuracy of the cigarette starting position, ensuring that the mechanical parts of the laser punching equipment are accurately calibrated and stable in operation. It overcomes the shortcomings of long time and low accuracy in adjusting the cigarette starting position; it solves the problem that the position of the focusing head lens in the online laser punching optical path of the cigarette is difficult to adjust due to the large deviation of the center point of the cigarette. Experiments have proved that when the calibration fixture provided in the embodiment of the present application is used to adjust the starting position of the online laser punched cigarette, the adjustment of the starting position of the online laser punched cigarette can be completed within 10 minutes, and the technical requirements of the three points of the center point of the cigarette wheel, the center point of the cigarette, and the center point of the laser punching drum wheel are accurately guaranteed to be in a straight line.
