Description

[0002] Tipping paper, also known as tipping paper, is the paper used to wrap around the outside of the cigarette filter. Its main function is to bond the filter rod to the end of the tobacco rod.

[0003] Laser punching technology for cigarette tipping paper is an advanced technology used in the cigarette rolling process. It uses laser to punch microholes in the middle of the cigarette filter rod.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0035] See also Figure 1 - Fig.10 A laser punching device for tipping paper comprises a liquid crystal elastomer 6, a trigger component is provided on the lower surface of the liquid crystal elastomer 6, a detection component and a punching mechanism are provided on the liquid crystal elastomer 6, the punching mechanism comprises a punching component and a hole-filling component, after the punching component completes punching of the tipping paper, the tipping paper is transmitted to the detection component, the detection component emits a light beam, the light beam passes through the punched holes and irradiates the liquid crystal elastomer 6 to cause a photomechanical effect, so that the liquid crystal elastomer 6 produces mechanical deformation, when the punching component misses and the holes in the tipping paper are uneven, the light beam is not irradiated on the liquid crystal elastomer 6, the liquid crystal elastomer 6 does not produce mechanical deformation, causing rebound, and the trigger component is passively triggered to release the mask of the hole-filling component, so that the hole-filling component performs hole-filling on the tipping paper.

[0036] The present invention sets a detection component to emit a light beam, and the light beam shines on the liquid crystal elastomer 6 through the holes on the tipping paper. The liquid crystal elastomer 6 generates a photomechanical effect under the action of light and produces mechanical deformation. The punching component performs laser punching on the tipping paper. After the punching is completed, the tipping paper is transmitted to the detection component. If the punching component misses a hole, making the holes in the tipping paper uneven, the light beam emitted by the detection component is blocked by the tipping paper and does not shine on the liquid crystal elastomer 6. The liquid crystal elastomer 6 does not produce mechanical deformation and causes rebound, then the trigger component will be passively triggered to release the mask on the hole-filling component, so that the hole-filling component supplements the holes in the tipping paper, thereby avoiding the situation where the tipping paper is missed.

[0037] In an embodiment further provided by the present invention, the material of the liquid crystal elastomer 6 is a filler mixed with photochromic molecules and nano fillers.

[0038] Specifically, the liquid crystal elastomer 6 is a special polymer material that combines the ordered arrangement of liquid crystals and the flexibility of elastomers. Under the irradiation of light, the liquid crystal elastomer 6 can change its shape. After the light is removed, the liquid crystal elastomer 6 can return to its original ordered state, achieving reversible deformation. The photochromic molecules added therein will undergo a photochemical reaction under light, causing the order of the liquid crystal elastomer 6 to decrease, and even causing it to undergo a phase transition, thereby causing the liquid crystal elastomer 6 to shrink or even bend. Nanofillers can improve the physical properties of the liquid crystal elastomer 6, making the mechanical deformation it produces larger, thereby driving the operation of mechanical components.

[0039] Furthermore, the detection component is located directly above the liquid crystal elastomer 6, and between the two is the tipping paper transmitted thereafter after punching. The punching component and the hole-filling component have the same structure. The punching component is located in front of the liquid crystal elastomer 6, and performs conventional punching on the tipping paper. The hole-filling component is located behind the liquid crystal elastomer 6 and the detection component, and performs hole-filling on the tipping paper.

[0052] Specifically, the spotlight 501 emits a light beam, and the converging lens 503 reduces the divergence of the light beam, making the light beam more intense.

[0053] Furthermore, there are three second limiting rollers 505 , which are located on the same horizontal plane, and the first two are mirror-symmetrical about the perpendicular midline of the lamp holder 5 , and the third one is mirror-symmetrical to the second one about the perpendicular midline of the hole-filling component.

[0054] In an embodiment further provided by the present invention, the trigger assembly includes a first connecting rod 601 connected to the lower surface of the liquid crystal elastomer 6, one end of the first connecting rod 601 passes through the trigger slot 105 and is rotatably connected to the second connecting rod 602, one end of the second connecting rod 602 is rotatably connected to the connecting shaft 603, one end of the connecting shaft 603 is rotatably connected to the third connecting rod 604, one end of the third connecting rod 604 is rotatably connected to the fourth connecting rod 606, one side surface of the fourth connecting rod 606 is connected to a rotating shaft 605, one end of the fourth connecting rod 606 is rotatably connected to a sliding bar 607, one end of the sliding bar 607 is fixedly connected to a baffle 608, one end of the rotating shaft 605 is rotatably connected to the inside of the shell 1, and the sliding bar 607 slides in cooperation with the sliding slot 106.

[0057] In an embodiment further provided by the present invention, a winding roller 8 is provided on one side surface of the outer shell 1, one end of the winding roller 8 is connected to a winding rod 801, one end of the winding rod 801 passes through the same side surface of the outer shell 1 and is connected to a transmission gear 802, the transmission gear 802 is meshed with a driving gear 803, one end of the driving gear 803 is connected to a driving rod 804, one end of the driving rod 804 is provided with a driving motor 805, and the output end of the driving motor 805 is connected to one end of the driving rod 804.

[0058] Specifically, the driving motor 805 drives the driving gear 803 to rotate, and the transmission gear 802 reduces the rotation speed and drives the winding roller 8 to rotate. The rotation of the winding roller 8 drives the tipping paper to be wound up and transmitted on the device.

[0059] When the present invention is in use, the tipping paper roll that needs to be punched is placed on the winding roller 2, the paper is drawn out through the first first limiting roller 201, and after being wound around the surface of the tension control roller 202, it passes through the second first limiting roller 201 and the first adjusting roller 204 in sequence, and then after being attached to the surface of the transmission roller 704, it passes through the second adjusting roller 204, is connected to the bottom of the three second limiting rollers 505, and finally is connected to the winding roller 8 for winding; then the telescopic rod 203 is used to telescopically adjust the position of the tension control roller 202, so as to adjust the tension of the tipping paper. After the tension is adjusted, the adjusting motor 403 is then started to drive the adjusting screw rod 404 to rotate, and the adjusting block 405 moves the adjusting screw rod 404 to rotate. The rotational movement of the rod 404 is converted into a lifting movement, and the matching block 407 slides on the matching rod 406 to cooperate with the adjustment block 405 for lifting and lowering, and drives the second connecting plate 408 to perform precise lifting and lowering movements, thereby driving the convex lens 306 to move up and down to change the focal position and adjust the size of the punched holes. Then, according to the arrangement of the holes to be punched, the telescopic rod 409 is controlled and adjusted to adjust the front and rear positions of the punching assembly so that the position of the punching assembly meets the arrangement of the holes; then the device is started, the driving motor 805 drives the driving gear 803 to rotate, the transmission gear 802 reduces the speed and drives the winding roller 8 to rotate, and the winding roller 8 rotates to drive the tipping paper to be rolled up, and makes it in the device The laser beam is transmitted on the optical fiber 301, the optical core 302 transmits the laser, the collimator 305 converts the point light into a parallel light source to improve the beam quality, the convex lens 306 focuses the parallel light beam, and the nozzle 310 emits the focused laser to perform laser drilling on the tipping paper. When the punched tipping paper is transmitted to the bottom of the detection component, the spotlight 501 emits a light beam, and the converging lens 503 reduces the divergence of the light beam, so that the light beam is more strongly irradiated on the surface of the tipping paper. The hole causes the transmitted light beam to irradiate the liquid crystal elastomer 6. Under the action of light, the liquid crystal elastomer 6 undergoes a photomechanical effect, generates a mechanical deformation, bends and warps, and causes the trigger component to stay in the locked position to block the hole filling group. If the punching assembly misses punching holes in the tipping paper, making the holes uneven, the light beam emitted by the detection assembly is blocked by the tipping paper and does not irradiate the liquid crystal elastic body 6. The liquid crystal elastic body 6 does not produce mechanical deformation, causing rebound. During the rebound process, the first connecting rod 601 is driven to move downward, and the downward movement of the first connecting rod 601 drives the other end of the second connecting rod 602 to tilt up, and then drives the third connecting rod 604 to rotate along its own center point, thereby driving the fourth connecting rod 606 to rotate with the rotating shaft 605 as the axis, and then drives the sliding bar 607 to slide inward in the trigger slot 105, and finally drives the baffle 608 to slide inward and no longer block the laser, so that the hole-filling assembly can fill holes in the unpunched positions of the tipping paper;The staff can calculate the time for the liquid crystal elastic body 6 to rebound and drive the trigger component to leave the locked position, and the time for the unpunched position of the tipping paper to reach the hole-filling component through limited experiments, so as to adjust the lengths of the first connecting rod 601, the second connecting rod 602, the third connecting rod 604 and the fourth connecting rod 606 to make the two times equal, so that the hole-filling position is correct, and the device can passively fill the missed tipping paper. ;

[0060] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
