DETAILED DESCRIPTION

[0023] The following will refer to the attached Figures 1 to 8 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention. Example

[0024] A laser punching device for cigarette tipping paper, as shown in the attached Figure 1 As shown, the frame 3 includes two longitudinal bars along the front-to-back direction and two transverse bars along the left-to-right direction. The longitudinal bars and the transverse bars form a frame shape, and a support leg 1 is provided at the bottom. A laser punching mechanism 10 and a movable carrying plate 8 are provided on the frame 3. The laser punching mechanism 10 includes a bracket and a laser head. A linear slide 4 is provided on the longitudinal bar. The carrying plate 8 is slidably arranged in the linear slide 4. By placing the cut tipping paper on the carrying plate 8, the carrying plate 8 drives the tipping paper to move under the laser punching mechanism 10 to achieve the punching of the tipping paper. This part is the existing technology and will not be described in detail here.

[0025] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, five through holes are provided on the carrier plate 8, and the through holes are respectively arranged in the middle and around the carrier plate 8, wherein a rotating plate 7 flush with the top of the carrier plate 8 is rotatably arranged in the through hole in the middle, and a top column 9 is arranged in the through holes on the surroundings. In a natural state, the top column 9 is not higher than the top of the carrier plate 8, and connecting blocks 13 are provided at the left and right ends of the front side of the carrier plate 8. The connecting block 13 is provided with a rotating shaft along the left and right directions, and a first gear 15 and an "F"-shaped limiting pressure strip 16 are rotatably connected through the rotating shaft, and a rotating rod 14 is fixedly provided between the two first gears 15, and the rotating rod 14 is fixedly connected to the top block 6, and a first gear 15 and a first gear 15 are provided near the front side of the frame 3. 15 is adapted to the first rack 2. When the first gear 15 moves close to the first rack 2, the first gear 15 moves along the first rack 2 above the first rack 2, driving the limiting pressure strip 16, the rotating rod 14 and the top block 6 to rotate. A top plate 21 is provided at the bottom of the four top columns 9. When the top block 6 rotates, the top plate 21 and the top column 9 are pushed to move upward. A second gear 23 is provided at the bottom of the rotating plate 7. The axis of the second gear 23 is along the vertical direction. A second rack 19 adapted to the second gear 23 is provided on the frame 3 through the connecting frame 18. When the supporting plate 8 moves, the second gear 23 moves along the second rack 19, and the rotating plate 7 is driven to rotate through the second gear 23.

[0026] Working principle: when the carrying plate 8 moves, it drives the second gear 23 to move along the second rack 19 and rotate, thereby driving the rotating plate 7 to rotate. When the rotating plate 7 rotates, it can move relative to the tipping paper to avoid adhesion to the tipping paper; when the carrying plate 8 moves forward, after the first gear 15 contacts the first rack 2, the first gear 15 moves along the first rack 2 and rotates, driving the limiting pressure strip 16 to move away from the carrying plate 8, no longer limiting, driving the top block 6 to move to the bottom of the top plate 21, and pushing the top plate 21, driving the top column 9 to move upward through the top plate 21, and driving the tipping paper to rise to a certain height through the top column 9.

[0027] In addition, it should be noted that in this embodiment, a limit spring 20 is provided between the top plate 21 and the bearing plate 8, and a limit torsion spring is provided between the connecting block 13 and the limit pressure strip 16. When not subject to external force, the limit pressure strip 16 can be limited, and the top of the top column 9 can be lower than the through hole to ensure the position of the tipping paper. In addition, the limit pressure strip 16 can also be made of magnetic material. In the natural state, it can be attracted to the bearing plate 8, and the top column 9 descends by its own gravity to achieve the limiting effect.

[0028] In addition, it should be noted that in this embodiment, a handle 5 is rotatably provided on the rotating rod 14. The rotating rod 14 can be pushed and pulled by the handle 5 to move forward and backward without affecting the rotation of the rotating rod 14.

[0029] In addition, it should be noted that in the present embodiment, the rotating plate 7 and the top column 9 are both cylindrical, the top column 9 is threadedly connected to the bearing plate 8, and is provided with a ball, that is, a ball screw structure is adopted, and the bottom of the top column 9 is rotatably arranged on the top plate 21, and can rotate when the top column 9 rises. When removing the tipping paper, even if slight adhesion occurs, the top column 9 can be rotated to separate the top column 9 from the tipping paper, thereby facilitating paper removal.

[0030] When in use, first use the handle 5 to pull the carrying plate 8 to the front direction. At this time, the rear end of the limiting pressure strip 16 is raised and away from the carrying plate 8, and the top column 9 is raised. The cut tipping paper can be placed on the carrying plate 8 and temporarily supported by the top column 9. Then, the carrying plate 8 is pushed backward by the handle 5. During the movement, the top column 9 first drops, so that the tipping paper is placed flat on the carrying plate 8. Then, the limiting pressure strip 16 approaches the carrying plate 8 to press the tipping paper, and the carrying plate 8 is continued to move backward until the tipping paper and the laser punching hole are After the mechanism 10 corresponds, the laser punching mechanism 10 is started to punch holes in the tipping paper. After punching, the carrying plate 8 is immediately pushed and pulled to drive the rotating plate 7 to rotate to avoid adhesion between the rotating plate 7 and the tipping paper after punching. Then the carrying plate 8 is moved to correspond to the laser punching mechanism 10 to complete the next punching. By analogy, the entire tipping paper is punched. After the punching is completed, the carrying plate 8 is moved to the front end, the limiting pressure strip 16 no longer limits the tipping paper, and the top column 9 lifts the tipping paper, and the tipping paper can be replaced.

[0031] When the first gear 15 is in contact with the first rack 2, the first gear 15 rotates, driving the limiting pressure strip 16 to move, so that the limiting pressure strip 16 is away from the carrying plate 8 and no longer limits the loading paper, thereby facilitating the loading paper limiting during punching; when the first gear 15 rotates, it drives the rotating rod 14 and the top block 6 to rotate in turn, and drives the top plate 21 and the top column 9 to rise in turn through the top block 6, that is, when the limiting pressure strip 16 is no longer limited to the loading paper, the top column 9 can also lift the loading paper to a certain height, thereby facilitating the replacement of the loading paper; when the carrying plate 8 moves, it can drive the rotating plate 7 to rotate. After punching, the rotating plate 7 is immediately controlled to rotate, which can avoid the situation where the loading paper and the carrying plate 8 are adhered; the whole process of the present invention only needs to control the carrying plate 8 to move back and forth, and the operation is simple and convenient. Example

[0032] As attached Figure 1 , Figure 4As shown, the difference from the first embodiment is that in this embodiment, a fan blade 24 is provided at the bottom of the rotating plate 7. Specifically, a connecting column 22 is provided at the bottom of the rotating plate 7, and the second gear 23 is sleeved on the connecting column 22. The bottom of the connecting column 22 is connected to the fan blade 24 through a reciprocating control mechanism 25. When the connecting column 22 makes forward and reverse motions, the fan blade 24 always rotates in one direction.

[0033] Working principle: When the supporting plate 8 moves back and forth, it drives the rotating plate 7 to rotate, and then drives the connecting column 22 and the fan blade 24 to rotate, and an upward airflow is generated through the fan blade 24. After punching, when the temperature is high, by pushing and pulling the supporting plate 8 to move, the temperature near the supporting plate 8 can be timely reduced through the airflow, avoiding the adhesion of the connecting device under high temperature.

[0034] In this embodiment, the fan blades 24 can move in coordination with the various structures, and airflow is generated immediately during the punching process to reduce the temperature, without the need to install a separate cooling device.

[0035] As attached Figure 1 , Figure 4 , Figure 7 , Figure 8 As shown, the reciprocating control mechanism 25 includes a third gear 255 fixedly connected to the connecting column 22, the third gear 255 is meshedly connected with the fourth gear 254, the fourth gear 254 is rotatably and slidably set in an arcuate slide groove 251, and also includes a fifth gear 252 and a sixth gear 253 that are meshed and connected, the fourth gear 254 can be meshed and connected with the fifth gear 252 or the sixth gear 253 by sliding, the sixth gear 253 is fixedly connected to the fan blade 24, the third gear 255, the fifth gear 252 and the sixth gear 253 are relatively rotatably set on the bearing plate 8, and the arcuate slide groove 251 is relatively fixedly set on the bearing plate 8. Specifically, a certain fixing frame (not shown in the figure) can be set under the bearing plate 8, the third gear 255, the fifth gear 252 and the sixth gear 253 can be rotatably set on the fixing frame, and the arcuate slide groove 251 is fixed on the fixing frame to realize the installation of various parts.

[0036] Working principle: When the connecting column 22 rotates clockwise, Figure 7 , driving the third gear 255 to rotate clockwise, the third gear 255 drives the fourth gear 254 to slide to the clockwise end (right end in the figure) of the arc-shaped slide slot 251, and the fourth gear 254 rotates counterclockwise, thereby driving the sixth gear 253 to rotate clockwise, and the sixth gear 253 drives the fan blade 24 to rotate clockwise to generate an upward airflow; when the connecting column 22 rotates counterclockwise, refer to the attached Figure 8, driving the third gear 255 to rotate counterclockwise, the third gear 255 drives the fourth gear 254 to slide to the counterclockwise end of the arc-shaped slide groove 251 (the left end on the way), and the fourth gear 254 rotates clockwise, the fourth gear 254 drives the fifth gear 252 to rotate counterclockwise, the fifth gear 252 drives the sixth gear 253 to rotate clockwise, and the sixth gear 253 drives the fan blade 24 to rotate clockwise to generate an upward airflow; thereby, when the rotating plate 7 rotates forward and reversely, the fan blade 24 always rotates in one direction.

[0037] In addition, it should be noted that the fourth gear 254 should be provided with a certain damping to ensure that when the third gear 255 switches forward and reverse rotations, it can slide smoothly along the arc-shaped slide groove 251 and does not rotate when sliding.

[0038] As attached Figure 1 , Figure 2 As shown, a rodless cylinder is provided on one side of the frame 3, which may be a magnetic rodless cylinder. The rodless cylinder includes a guide rod 12 and a slider 11. The slider 11 is fixedly connected to the connecting block 13 through a connecting plate 17. The rodless cylinder is electrically connected to a controller to control the movement of the supporting plate 8. Specifically, the supporting plate 8 is controlled to move forward and backward once after each processing, thereby driving the fan blades 24 to rotate and dissipate heat in time.

[0039] During specific operation, the carrier plate 8 is controlled by an electric control. Specifically, the working process of the carrier plate 8 is as follows: in the initial position, the carrier plate 8 is located at the front end of the frame 3, and then the carrier plate 8 moves backward to the first punching position corresponding to the laser punching mechanism 10. After the first punching, the carrier plate 8 moves forward a certain distance, and then moves backward to the second punching position corresponding to the laser punching mechanism 10. After the second punching, the carrier plate 8 moves forward a certain distance, and then moves backward to the third punching position corresponding to the laser punching mechanism 10, and so on, until the punching on a piece of tipping paper is completed, and finally the carrier plate 8 is reset to the initial position for paper replacement.

[0040] In this embodiment, the movement of the carrier plate is controlled by electric control, and only the paper needs to be replaced manually. The operation is simple and convenient, saving manpower. In addition, the relative position of the carrier plate 8 and the laser punching mechanism 10 can be more accurately controlled by electric control, and the punching is more accurate.
