[0002] Tipping paper, also known as cigarette tipping paper, is a cigarette packaging material used as the outer packaging of the filter tip. It wraps around the filter tip and attaches the filter to the end of the cigarette pack. Cigarette tipping paper is the only cigarette packaging material that comes into direct contact with the human body. With people's pursuit of quality of life and to enhance consumers' sensory experience, the market has created new demands for the taste effects of tipping paper.

The hot stamping tipping paper includes: tipping paper base paper; an ink layer printed on the surface of the tipping paper base paper; a mixed flavor layer coated on the surface of the ink layer; a nano-antioxidant layer printed on the surface of the mixed flavor layer; and a hot stamping layer transferred on the surface of the nano-antioxidant layer.

[0004] However, in actual use, the inventors found that the traditional tipping paper has a simple structure, no flavor, and poor heat insulation when the cigarette stick burns to the end, making the filter stick easy to burn the mouth and affecting the smoking experience. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a cigarette tipping paper laminating machine and laminating process. This increases the gap between the outer layer of the tipping paper and the filter rod, improves the heat insulation effect of the tipping paper, prevents the filter rod from burning the mouth, and enhances the rich and lasting flavor and smoking experience.

[0019] As a preferred embodiment, a lamination process for a cigarette tipping paper laminating machine includes the following steps:

[0020] Step 1, the groove pressing process: the winding drum releases a layer of inner paper and lays it flat on the first conveyor belt, located between the first and second guardrails. Driven by the first limiting track, the strip pressing plate presses strip grooves evenly at intervals on the surface of the inner paper.

[0021] Step 2, filling process: The paper feeding component pulls the heat insulation paper into the strip groove of the inner paper and applies adhesive to the side walls of the strip groove intermittently.

[0024] The beneficial effects of this invention are:

[0025] (1) In this invention, by setting up a conveying mechanism and a filling mechanism, on the one hand, before the inner paper and outer paper are bonded together to form a tipping paper, strip grooves can be pressed evenly at intervals on the surface of the inner paper to form a corrugated paper shape, and wavy heat insulation paper is folded inside the strip grooves, which increases the gap between the outer layer of the tipping paper and the filter rod, preventing the heat inside the filter rod from being directly transferred to the outer layer of the tipping paper. At the same time, the heat insulation paper also blocks the heat transfer inside the filter rod, improving the heat insulation effect of the tipping paper and preventing the filter rod from burning the mouth; on the other hand, flavor beads can be filled in the crests and troughs of the wavy heat insulation paper. The flavor beads are evenly distributed, the flavor is rich and long-lasting, and the sucking effect is improved.

[0026] (2) In this invention, the bending component and the paper feeding component work together to automatically fold the heat insulation paper into a wave shape from the end near the electric gripper, so that the winding wheel continues to release the heat insulation paper, preventing the heat insulation paper from being pulled and broken, and improving the forming effect of the wave-shaped heat insulation paper; on the other hand, the wave-shaped heat insulation paper not only has the support of the inner paper's strip groove for shaping, preventing the strip groove from collapsing and deforming, but also can separate the flavor beads at intervals, ensuring that the flavor beads are evenly distributed in the strip groove, with a lasting flavor and a better taste.

[0027] (3) The cleaning mechanism provided in this invention can, on the one hand, clean the glue solidified on both sides of the composite tipping paper, prevent the edges of the tipping paper from sticking together after rolling, and thus prevent the tipping paper edges from tearing, thereby improving the aesthetics of the tipping paper; on the other hand, it can sterilize the outer paper of the tipping paper, prevent the tipping paper from contacting the lips and causing the spread of bacteria, thereby improving the hygiene of the tipping paper.

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0050] Example 1

[0051] like Figures 1-19 As shown, a cigarette tipping paper laminating machine includes a conveying mechanism 2, a filling mechanism 3, a laminating mechanism 4, and a cleaning mechanism 5, all mounted on a frame 1.

[0052] The conveying mechanism 2 includes a carrying component 21 disposed on the frame 1, an unwinding component 22 disposed on the frame 1 for laying inner paper flat on the carrying component 21, and a pressing component 23 disposed on the carrying component 21 for pressing a strip-shaped groove on the surface of the inner paper.

[0053] The unwinding assembly 22 releases a layer of inner paper 6 and lays it flat on the transport assembly 21. The grooving assembly 23 presses strip-shaped grooves evenly at intervals on the surface of the inner paper 6. The filling mechanism 3 releases a layer of heat-insulating paper 7 into the strip-shaped groove and folds the heat-insulating paper 7 into a wavy shape and sticks it to the inner side wall of the strip-shaped groove to support and shape the strip-shaped groove. Then, flavor beads 8 are added into the strip-shaped groove. The composite mechanism 4 releases a layer of outer paper 9 and lays it flat on the surface of the inner paper 6, and presses the outer paper 9 and the inner paper 6 together to bond them together. The cleaning mechanism 5 scrapes off the glue that has solidified on both sides of the composite paper and removes dust, while sterilizing the surface of the outer paper.

[0054] In this embodiment, the conveying mechanism 2 and the filling mechanism 3 work together to achieve the following: First, before the inner paper 6 and the outer paper 9 are bonded together to form the tipping paper, strip grooves can be pressed evenly and at intervals on the surface of the inner paper 6 to form a corrugated paper shape. Corrugated heat insulation paper is folded inside the strip grooves, which increases the gap between the outer layer of the tipping paper and the filter rod, preventing the heat inside the filter rod from being directly transferred to the outer layer of the tipping paper. At the same time, the heat insulation paper also blocks the heat transfer inside the filter rod, improving the heat insulation effect of the tipping paper and preventing the filter rod from burning the mouth. Second, flavor beads can be filled in the crests and troughs of the corrugated heat insulation paper. The flavor beads are evenly distributed, the flavor is rich and long-lasting, and the smoking experience is improved.

[0055] In detail, firstly, the take-up drum 221 releases a layer of inner paper, which is laid flat on the first conveyor belt 211 and positioned between the first guardrail 213 and the second guardrail 215. Driven by the first limiting rail 236, the strip pressure plate 231 presses strip grooves evenly and at intervals onto the surface of the inner paper. Then, the paper feeding assembly 32 pulls the heat insulation paper into the strip grooves of the inner paper and intermittently applies adhesive to the side walls of the strip grooves. Starting from the electric gripper 329, the bending assembly 33 folds the heat insulation paper into a wavy shape, so that the wavy heat insulation paper is formed and bonded to the strip grooves. Flavor beads are added into the strip grooves on both sides of the paper, so that the flavor beads are distributed between the troughs and crests of the corrugated insulation paper. Then, the glue coating cylinder 41 applies glue to the lower surface of the outer paper, and the pressure roller 42 presses the outer paper onto the inner paper for bonding and lamination. The strip pressure plate 231 moves horizontally away from the strip groove of the inner paper under the drive of the first limit track 236, and the output roller 43 pulls the composite paper out. Then, before the composite paper is output, the scraper 52 cleans the glue that has solidified on both sides of the composite paper, the blower 53 cleans the dust on the composite paper, and at the same time, the ultraviolet lamp sterilizes the surface of the outer paper.

[0056] Furthermore, such as Figures 5-8 As shown, the transport component 21 includes a first conveyor belt 211 disposed on the frame 1, a plurality of strip grooves 212 formed on the first conveyor belt 211, a first enclosure 213 disposed on the first conveyor belt 211, a plurality of first vertical holes 214 formed on the first enclosure 213 and respectively corresponding to the positions of the strip grooves 212, a second enclosure 215 disposed on the first conveyor belt 211, and a plurality of second vertical holes 216 formed on the second enclosure 215 and respectively corresponding to the positions of the strip grooves 212;

[0057] The unwinding assembly 22 includes a take-up drum 221 mounted on the frame 1 and wound with inner paper, and a traction roller 222 mounted on the frame 1 for drawing the inner paper onto the first conveyor belt 211.

[0058] In this embodiment, by cooperating with the unwinding component 22 and the transport component 21, a layer of inner paper can be automatically and continuously laid flat on the first conveyor belt 211, and the inner paper on the first conveyor belt 211 can be limited.

[0059] In detail, the first conveyor belt 211 runs at a constant speed under the existing power, and the traction roller 222 guides the inner paper on the winding drum 221 to be laid flat on the first conveyor belt 211. At the same time, the first guardrail 213 and the second guardrail 215 cooperate to limit the inner paper on the first conveyor belt 211 to prevent the inner paper on the first conveyor belt 211 from being misaligned.

[0060] Furthermore, such as Figures 5-8 As shown, the pressing groove assembly 23 includes several sets of strip-shaped pressing plates 231 that are respectively raised and lowered in the first vertical hole 214 and matched with the strip-shaped groove 212, limiting grooves opened on the strip-shaped pressing plates 231, elastic telescopic members 232 set at the top of the first vertical hole 214, lifting blocks 233 set at the end of the elastic telescopic members 232 and slidingly engaged with the limiting grooves, a first elastic member 234 set between the lifting blocks 233 and the end of the strip-shaped pressing plates 231, a first extension rod 235 set at the end of the strip-shaped pressing plates 231, and a first limiting track 236 set on the frame 1 for driving the first extension rod 235 to move the strip-shaped pressing plates 231 horizontally and lower.

[0061] It should be noted that the first limiting track 236 includes a first pushing part 2361, a first sinking part 2362, and a second pushing part 2363 in sequence along the inner paper's forward direction. Before the unwinding assembly 22 lays the inner paper flat on the first conveyor belt 211, the first pushing part 2361 drives the strip pressure plate 231 to move horizontally to avoid the inner paper. After the inner paper is laid flat on the first conveyor belt 211, the strip pressure plate 231 moves horizontally to reset. Then, the first sinking part 2362 drives the strip pressure plate 231 to descend into the strip groove 212, pressing the inner paper into the strip groove. During the working time of the filling mechanism 3 and the laminating mechanism 4, the strip pressure plate 231 is always pressed into the strip groove 212, so that the strip groove of the inner paper maintains its shape. Before the cleaning mechanism 5 works, the second pushing part 2363 drives the strip pressure plate 231 to be horizontally pulled out of the strip groove 212, which facilitates the output of the laminated paper.

[0062] It is worth mentioning that the elastic telescopic component 232 consists of an existing telescopic rod and a spring.

[0063] In this embodiment, the groove pressing component 23 can be used to press strip-shaped grooves evenly at intervals on the surface of the inner paper.

[0064] In detail, before the unwinding assembly 22 lays out the inner paper, the first pushing part 2361 of the first limiting rail 236 drives the first extension rod 235 to move the strip pressure plate 231 horizontally, so that the strip pressure plate 231 moves away from the position above the strip groove 212 of the first conveyor belt 211, avoiding the laid-out inner paper. After the unwinding assembly 22 lays out the inner paper, the strip pressure plate 231 is horizontally reset to the position above the strip groove 212 of the first conveyor belt 211 under the elastic force of the first elastic member 234. Then, the first sinking part 2362 of the first limiting rail 236 drives the first extension rod 235, carrying the strip pressure plate 231, descends into the strip groove 212 of the first conveyor belt 211, pulling the winding drum 221 to release a certain length of inner paper, causing the inner paper to sink into the strip groove 212 to form a strip groove. During the working time of the filling mechanism 3 and the composite mechanism 4, the strip pressure plate 231 is always pressed into the strip groove 212, so that the strip groove of the inner paper maintains its shape. Before the cleaning mechanism 5 works, the second propulsion part 2363 of the first limit track 236 drives the first extension rod 235 to horizontally pull the strip pressure plate 231 out of the strip groove 212, which facilitates the output of the composite paper.

[0065] Furthermore, such as Figure 4 and Figures 9-14 As shown, the filling mechanism 3 includes a second conveyor belt 31 disposed on the frame 1 and working synchronously with the first conveyor belt 211, a paper feeding assembly 32 disposed on the second conveyor belt 31, a bending assembly 33 disposed on the paper feeding assembly 32 and used to fold the heat insulation paper into a wavy shape, and a feeding assembly 34 disposed on the frame 1 and used to add flavor beads into the strip groove.

[0066] The paper feeding assembly 32 includes a third baffle 321 disposed on the second conveyor belt 31, several sets of third vertical holes opened on the third baffle 321, a lifting block 322 slidably disposed on the third vertical hole, a strip 323 penetrating and slidably disposed on the lifting block 322, a second elastic member disposed between the lifting block 322 and the lower end of the third vertical hole, a third elastic member 324 disposed between the end of the strip 323 and the lifting block 322, several sets of take-up wheels 325 disposed on the second conveyor belt 31 and respectively located directly below the strip 323, and several sets of... The conveyor belt 31 includes a clamping roller 326 for pulling the heat insulation paper on the take-up roller 325 onto the first conveyor belt 211; a suspension rod disposed at the end of the strip 323; a suspension plate 327 disposed at the end of the suspension rod; two sets of glue-applying rollers 328 disposed at the bottom of the suspension plate 327 for intermittently applying adhesive to the sidewalls of the strip grooves of the inner paper; an electric gripper 329 disposed at the bottom of the suspension plate 327; a second extension rod 3291 disposed at the end of the strip 323; and a second limiting track 3292 disposed on the frame 1 for driving the second extension rod 3291 to move the strip 323 horizontally and descend.

[0067] It should be noted that the second limiting track 3292 includes, in sequence along the inner paper's forward direction, a second sinking part 32921, a third pushing part 32922, and a lifting part 32923. When it is necessary to feed the heat insulation paper into the strip groove 212, the second sinking part 32921 drives the strip 323 to descend, so that the electric gripper 329 at the end of the strip 323 clamps the cut end of the heat insulation paper. Then, the third pushing part 32922 pushes the strip 323 horizontally into the strip groove 212, so that the electric gripper 329 delivers the heat insulation paper into the strip groove of the inner paper. After the bending assembly 33 folds the heat insulation paper in the strip groove into a wavy shape, the strip 323 rises and resets along the lifting part 32923 under the drive of the second elastic member, so that the strip 323 can be horizontally reset under the drive of the third elastic member 324.

[0068] It is worth mentioning that the glue-applying roller 328 has vertical glue outlet holes on its side wall, and the two glue-applying rollers 328 are staggered at the bottom of the hanging plate 327. This ensures that the bonding points of the two glue-applying rollers 328 on the two sides of the strip groove of the inner paper are staggered, which facilitates the alternating bonding of the crests and troughs of the corrugated heat insulation paper to the two sides of the strip groove. At the same time, the lateral distance between the two staggered glue-applying rollers 328 is greater than the lateral distance between the two clamping rollers 326, so that the clamping rollers 326 will not obstruct the advance of the glue-applying rollers 328.

[0069] In this embodiment, the paper feeding assembly 32 can automatically pull a certain length of heat insulation paper into the strip groove of the inner paper, and keep the inner paper in an upright state.

[0070] In detail, the second conveyor belt 31 works synchronously with the first conveyor belt 211. The third vertical hole on the third enclosure 321 corresponds one-to-one with the position of the strip groove 212 on the second conveyor belt 31. When it is necessary to feed the heat insulation paper into the strip groove 212, the second sinking part 32921 of the second limiting rail 3292 drives the second extension rod 3291 to descend with the strip 323. The electric gripper 329 at the end of the strip 323 clamps the cut end of the heat insulation paper. The third pushing part 32922 of the second limiting rail 3292 drives the second extension rod 3291 to descend with the strip 323. The extension rod 3291 carries the strip 323 horizontally into the strip groove 212. At the same time, the take-up roller 325 releases the heat insulation paper, allowing a certain length of heat insulation paper to enter the strip groove of the inner paper. When the bending assembly 33 is working, the take-up roller 325 continues to release the heat insulation paper. After the bending assembly 33 folds the heat insulation paper in the strip groove into a wave shape, the strip 323 rises and resets along the lifting part 32923 under the drive of the second elastic element, so that the strip 323 can be horizontally reset under the drive of the third elastic element 324 for the next use.

[0071] Furthermore, such as Figures 10-13 As shown, the bending assembly 33 includes several sets of shafts 331 rotatably mounted on the strip 323 via torsion springs, a hanging plate 332 mounted at the lower end of the shafts 331, a bending roller 333 eccentrically mounted at the bottom of the hanging plate 332 and used to press the heat insulation paper onto the bonding point of the strip groove sidewall of the inner paper, a gear 334 mounted at the upper end of the shafts 331, a lead screw 335 mounted on the strip 323, a transmission block 336 threaded onto the lead screw 335, a rack 337 mounted on the side of the transmission block 336 and used to sequentially drive the gear 334, a first motor mounted on the strip 323 and used to drive the lead screw 335, a hydraulic component 338 mounted on the strip 323, and a cutter 339 mounted at the output end of the hydraulic component 338 and used to cut off the hydraulic component 338.

[0072] It should be noted that the bending rollers 333 on the two adjacent hanging plates 332 are staggered to facilitate the folding of the crests and troughs of the wavy heat insulation paper. At the same time, the lateral distance between the bending rollers 333 on the two adjacent hanging plates 332 is greater than the lateral distance between the two clamping rollers 326, so that the clamping rollers 326 will not obstruct the forward movement of the bending rollers 333.

[0073] In this embodiment, the bending component 33 and the paper feeding component 32 work together to automatically fold the heat insulation paper into a wave shape from the end near the electric gripper 329, so that the winding wheel 325 continues to release the heat insulation paper, preventing the heat insulation paper from being pulled and broken, and improving the forming effect of the wave-shaped heat insulation paper. On the other hand, the wave-shaped heat insulation paper not only has the support of the inner paper's strip grooves to shape it and prevent the strip grooves from collapsing and deforming, but also can separate the flavor beads at intervals, ensuring that the flavor beads are evenly distributed in the strip grooves, resulting in a lasting flavor and a better taste.

[0074] In detail, after the strip plate 323 feeds the heat insulation paper into the strip groove of the inner paper, the first motor drives the transmission block 336 to move horizontally through the lead screw 335. This causes the rack 337 on the side of the transmission block 336 to drive the gear 334 to rotate the hanging plate 332 at a certain angle through the shaft 331. This causes the bending rollers 333 of each hanging plate 332 to fold the heat insulation paper into a wave shape in sequence, and the crests and troughs of the wave-shaped heat insulation paper adhere to the side wall of the strip groove of the inner paper. Finally, the hydraulic component 338 drives the cutter 339 to descend and cut the heat insulation paper. The strip plate 323 rises and resets along the lifting part 32923 under the drive of the second elastic component, causing the bending rollers 333 to rise and detach from the crests and troughs of the wave-shaped heat insulation paper. The first motor drives the bending rollers 333 of each hanging plate 332 to rotate and reset through the lead screw 335. Finally, the strip plate 323 is reset horizontally under the drive of the third elastic component 324, ready for the next use.

[0075] Furthermore, such as Figure 4 and Figures 15-16 As shown, the feeding assembly 34 includes a horizontal cylinder 341 mounted on the frame 1, a rotating roller 342 that is clearance-fitted and rotatably mounted inside the horizontal cylinder 341, several sets of material leakage holes 343 opened at the bottom of the horizontal cylinder 341, several sets of concave cavities 344 opened on the outer wall of the rotating roller 342 and containing flavor beads, and a second motor 345 mounted on the frame 1 for driving the rotating roller 342.

[0076] It should be noted that by adjusting the rotation speed of the rotating roller 342, the speed at which the various cavities 344 on the outer wall of the rotating roller 342 intermittently pass through the material leakage hole 343 is the same as the forward speed of the first conveyor belt 211, so that when the various cavities 344 pass through the material leakage hole 343 in sequence, the strip groove 212 of the first conveyor belt 211 is exactly located directly below the material leakage hole 343.

[0077] In this embodiment, the feeding component 34 can automatically add flavor beads into the groove of the inner paper, so that the flavor beads are distributed in the troughs and crests of the wavy heat insulation paper.

[0078] In detail, the second motor 345 drives the rotating roller 342 to rotate at a constant speed, so that each cavity 344 of the rotating roller 342 passes through the position of the discharge hole 343 in sequence. The flavor beads in the cavity 344 fall into the inner paper's strip groove in the strip groove 212 of the first conveyor belt 211 in sequence through the discharge hole 343.

[0079] Furthermore, such as Figure 17As shown, the composite mechanism 4 includes a glue-applying cylinder 41 mounted on the frame 1 for applying glue to the lower surface of the outer paper, several sets of pressure rollers 42 mounted on the frame 1 for pressing the outer paper onto the inner paper for bonding and laminating, and an output roller 43 mounted on the frame 1 for outputting the composite paper.

[0080] It should be noted that before the composite paper is transferred from the pressure roller 42 to the output roller 43, the second propulsion part 2363 of the first limiting track 236 drives the first extension rod 235 to horizontally pull the strip pressure plate 231 out of the strip groove 212, which facilitates the output of the composite paper.

[0081] In this embodiment, the outer paper and inner paper can be bonded together to form a splicing paper by means of the composite mechanism 4.

[0082] In detail, the glue-coating cylinder 41 applies glue to the lower surface of the externally input outer paper, the pressure roller 42 presses the outer paper onto the inner paper for bonding and lamination, the strip pressure plate 231 moves horizontally away from the strip groove of the inner paper under the drive of the first limit track 236, and the output roller 43 pulls the laminated paper out.

[0083] Furthermore, such as Figures 17-19 As shown, the cleaning mechanism 5 includes a cleaning box 51 mounted on the frame 1, two sets of scrapers 52 symmetrically arranged inside the cleaning box 51 for cleaning the glue solidified on both sides of the composite paper, an ultraviolet lamp mounted on the top of the cleaning box 51, a blower 53 mounted on one side wall of the cleaning box 51, and a ventilation hole 54 mounted on the opposite side wall of the cleaning box 51.

[0084] In this embodiment, the cleaning mechanism 5 can, on the one hand, clean the glue that has solidified on both sides of the composite tipping paper, prevent the edges of the tipping paper from sticking together after winding, which would cause the edges of the tipping paper to tear and improve the appearance of the tipping paper; on the other hand, it can sterilize the outer paper of the tipping paper, prevent the tipping paper from contacting the lips and causing the spread of bacteria, and improve the hygiene of the tipping paper.

[0085] In detail, before the composite paper is output, the scraper 52 cleans the glue that has solidified on both sides of the composite paper, the blower 53 cleans the dust on the composite paper, and at the same time the ultraviolet lamp sterilizes the surface of the outer paper.

[0086] Example 2

[0087] like Figures 4-20 As shown, a compounding process for a cigarette tipping paper laminating machine includes the following steps:

[0088] Step 1, the groove pressing process: the winding drum 221 releases a layer of inner paper and lays it flat on the first conveyor belt 211 and is located between the first guardrail 213 and the second guardrail 215. Under the drive of the first limiting track 236, the strip pressing plate 231 presses strip grooves evenly at intervals on the surface of the inner paper.

[0089] Step 2, filling process: The paper feeding component 32 pulls the heat insulation paper into the strip groove of the inner paper and applies adhesive to the side walls of the strip groove intermittently. The bending component 33 starts from the electric gripper 329 and folds the heat insulation paper into a wave shape in sequence, so that the wave-shaped heat insulation paper is formed and adhered to the side walls of the strip groove. The feeding component 34 adds flavor beads into the strip groove, so that the flavor beads are distributed between the troughs and peaks of the wave-shaped heat insulation paper.

[0090] Step 3, the lamination process: the glue coating cylinder 41 applies glue to the lower surface of the outer paper, the pressure roller 42 presses the outer paper onto the inner paper for bonding and lamination, the strip pressure plate 231 moves horizontally away from the strip groove of the inner paper under the drive of the first limit track 236, and the output roller 43 pulls the laminated paper out.

[0091] Step four, cleaning process: Before the composite paper is output, the scraper 52 cleans the glue that has solidified on both sides of the composite paper, the blower 53 cleans the dust on the composite paper, and at the same time the ultraviolet lamp sterilizes the surface of the outer paper.
