Description

Technical Field

[0001] This utility model relates to the field of cigarette processing technology, and in particular to a coating structure with a laser-engraved aroma guiding area. Background Technology

[0002] The coating structure for cigarette processing with laser-engraved marking is an innovative achievement in the tobacco packaging field that integrates laser processing technology and coating process. Its core is to form a permanent mark on the surface of the coating or a specific functional layer of cigarette packaging through high-precision laser engraving, replacing the traditional printing marking method and achieving multiple goals such as enhanced anti-counterfeiting, quality upgrade and environmentally friendly production. It has been widely used in key links such as cigarette tipping paper, frame paper and cigarette box outer packaging.

[0003] Existing cigarette coating structures mostly focus on basic functions such as anti-counterfeiting, wear resistance, and aesthetic enhancement, while processes such as laser engraving and embossing printing are used to achieve product traceability and brand recognition improvement.

[0004] An existing patent (publication number: CN216100912U) discloses a laminating machine for packaging paper production. By moving two movable rings, it can position the relative positions of different materials, adapt to materials of different widths, and guide various materials when they are overlapped, reducing the probability of material deviation.

[0005] Existing patents offer solutions to the aforementioned problems, but their processing effects are unsatisfactory. They apply biodegradable water-based pressure-sensitive adhesive to the surface of the engraved breathable layer to form an easy-tear adhesive layer. However, due to the lack of a coating structure, this can easily lead to uneven adhesive layer application and the covering of microchannels, failing to meet the quality standards of cigarette tipping paper. This severely affects the aroma guiding effect and product quality, reducing the practicality of the device.

[0006] To address this, a coating structure with a laser-engraved fragrance guiding area is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a coating structure with a laser-engraved aroma guiding area, which can solve the problems of poor processing effect of existing coating structures. The existing coating structure coats the surface of the engraved breathable layer with biodegradable water-based pressure-sensitive adhesive to form an easy-tear adhesive layer. However, due to the lack of a coating structure, the adhesive layer is prone to uneven coating and covering of microchannels, which cannot meet the quality standards of cigarette tipping paper, seriously affecting the aroma guiding effect and product quality, and reducing the practicality of the device.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a coating structure with a laser-engraved fragrance guiding area, comprising a shell, a coating component fixedly connected to the front side inside the shell, and an adjusting component fixedly connected to the middle part inside the shell, the coating component comprising a liquid storage tank, a support provided at the top of the liquid storage tank, and a leakage cylinder rotatably connected inside the support, an infusion pump fixedly connected to the bottom right side of the liquid storage tank, and an infusion pipe provided between the infusion pump and the leakage cylinder.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 The present invention provides the following technical solution:

[0029] A coating structure with a laser-engraved fragrance guiding area includes a housing 1. A coating component 2 is fixedly connected to the front side inside the housing 1, and an adjustment component 3 is fixedly connected to the middle part inside the housing 1. The coating component 2 includes a liquid storage tank 201. A support 202 is provided on the top of the liquid storage tank 201, and a leakage cylinder 203 is rotatably connected inside the support 202. An infusion pump 204 is fixedly connected to the bottom right side of the liquid storage tank 201, and an infusion tube 205 is provided between the infusion pump 204 and the leakage cylinder 203.

[0030] In this embodiment: the infusion pump 204 and the infusion tube 205 are used together to smoothly deliver the fragrance liquid in the storage tank 201 to the leakage cylinder 203 through the infusion tube 205. Then, the liquid smoothly permeates into the sponge sleeve 7 through the holes on the surface of the leakage cylinder 203. During the delivery process, the laser-engraved substrate drives the sponge sleeve 7 and the leakage cylinder 203 to rotate. Utilizing the flexible and porous characteristics of the sponge sleeve 7, the fragrance liquid can be smoothly coated onto the laser-engraved fragrance guiding area of ​​the substrate, while avoiding damage to the engraved texture caused by hard contact. This achieves a precise match between the fragrance substance and the engraved structure, laying the foundation for the stable performance of the fragrance function after lamination and improving the processing efficiency of the product. Then, the rotating motor 304 drives the rotating disc 302 to rotate, which drives the adjusting roller 303 to move smoothly in the arc-shaped sliding cavity 6 on the surface of the fixed disc 301. This allows for flexible adjustment of the delivery posture and tension of the lamination and the substrate, ensuring the smooth delivery of the laser-engraved substrate and the outer lamination, guaranteeing the stable lamination operation, and improving the ease of use of the device.

[0031] Specifically, such as Figure 5 As shown, the adjustment assembly 3 includes two fixed circular plates 301, which are fixedly connected to both sides of the inner wall of the housing 1. Rotating circular plates 302 are rotatably connected inside the two fixed circular plates 301. Adjusting rollers 303 are rotatably connected at the four corners between the two rotating circular plates 302. A rotating motor 304 is fixedly connected to the right side of the right rotating circular plate 302.

[0032] Specifically, such as Figure 2 , Figure 5As shown, a fixing plate 4 is fixedly connected between the two fixed circular plates 301 on opposite sides, and cameras 5 are fixedly connected at the four corners on both sides of the surface of the fixing plate 4.

[0033] Specifically, such as Figure 5 As shown, each of the four corners of the two fixed circular plates 301 near the fixed plate 4 is provided with an arc-shaped sliding cavity 6, and the adjusting roller 303 is slidably connected inside the arc-shaped sliding cavity 6.

[0034] In this embodiment: the arc-shaped sliding cavity 6 forms a guiding structure, which drives the rotating disc 302 to rotate via the rotating motor 304. Simultaneously, the adjustment mechanism moves within the arc-shaped sliding cavity 6 to adjust the angle. This allows for flexible adjustment of the conveying posture and tension of the coating and the substrate. Simultaneously, the camera 5 collects the conveying status of both in real time and transmits the data to the control console 19. The control console 19 then fine-tunes the adjustment component 3 to ensure the smooth conveying of the laser-engraved substrate and the outer coating, guaranteeing the stable operation of the coating process and improving the processing efficiency of the product.

[0035] Specifically, such as Figure 2 , Figure 4 As shown, a sponge sleeve 7 is fitted onto the surface of the leakage cylinder 203.

[0036] Specifically, such as Figure 4 As shown, several rotating rollers 8 are rotatably connected to the top of the inside of the liquid storage tank 201, and the rotating rollers 8 are in contact with the sponge sleeve 7.

[0037] In this embodiment: the fragrance liquid is allowed to seep into the sponge sleeve 7 through the holes on the surface of the leakage cylinder 203 by the cooperation of the leakage cylinder 203. The flexible and porous nature of the sponge sleeve 7 can not only smoothly coat the fragrance liquid onto the laser-engraved fragrance guiding area of ​​the substrate, but also avoid damage to the engraved pattern caused by hard contact. At the same time, under the action of the rotating roller 8, the substrate can be restricted, and excess fragrance liquid can flow back to the liquid storage tank 201 through the gap between the rotating rollers 8, effectively reducing material waste and improving the ease of use of the coating component 2.

[0038] Specifically, such as Figure 2 , Figure 3 As shown, sliders 9 are slidably connected to the rear sides of both sides of the inner wall of the housing 1, and pressing rollers 10 are rotatably connected between the opposite sides of the two sliders 9. Cylinders 11 are fixedly connected to both sides of the top of the housing 1, and the output end of the cylinders 11 extends into the interior of the housing 1 and is fixed to the sliders 9. A support roller 12 is rotatably connected to the rear side of the bottom of the interior of the housing 1, and the support roller 12 is located at the bottom of the pressing roller 10.

[0039] Specifically, such as Figure 3As shown, the rear sides of both sides of the inner wall of the housing 1 are provided with slide grooves 13 for use with the slider 9. The front and rear sides of the slide grooves 13 are provided with positioning rods 14, and the slider 9 is slidably connected to the surface of the positioning rods 14.

[0040] Specifically, such as Figure 2 , Figure 3 As shown, a double-layer feeding device 15 is fixedly connected to the front side of the housing 1, and a winding device 16 is fixedly connected to the rear side of the housing 1. The top, bottom and rear sides of the front side of the housing 1 are provided with material inlets 17, and the top and bottom of the material inlets 17 are rotatably connected to rubber rollers 18.

[0041] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a control console 19 is fixedly connected to the front right side of the housing 1, and the control console 19 is electrically connected to the double-layer feeding device 15, the winding device 16, the cylinder 11, the adjusting component 3, and the coating component 2.

[0042] In this embodiment: Through the function of the control console 19, the operating parameters of the equipment can be adjusted according to the actual situation, and the double-layer feeding device 15 and the winding device 16 can be controlled to synchronously and smoothly release the laser-engraved substrate and the outer film, and orderly wind up the finished product. In addition, the transport speed can be adjusted to match the rhythm of each process, so as to realize the adjustment of the transport speed. After the substrate and the film are guided and protected by the rubber roller 18 at the feed port, they enter the housing 1 and the fragrance liquid is coated and the tension is adjusted in sequence. At the same time, the cylinder 11 is started, driving the slider 9 to move along the slide groove 13 under the constraint of the positioning rod 14, and synchronously driving the pressing roller 10 to move, so that the substrate and the film are tightly squeezed between the pressing roller 10 and the support roller 12 to complete the film coating operation, which improves the practicality of the device.

[0043] Working principle: When processing cigarette tipping paper, the laser-engraved tipping paper substrate and the outer film are first installed at the bottom and top of the double-layer feeding device 15, respectively. Then, the tipping paper substrate and the outer film pass through the two rubber rollers 18 at the top and bottom, respectively. The tipping paper substrate passes between the sponge sleeve 7 and the rotating roller 8, the adjusting roller 303, the pressing roller 10 and the support roller 12, and finally exits from the rear rubber roller 18 and winds around the winding device 16. The outer film passes through the adjusting roller 303, the pressing roller 10 and the support roller 12 in sequence inside the housing 1, and is wound together with the substrate after being bonded. After completing the preliminary preparation, the operator adjusts the operating parameters through the control panel 19. First, the infusion pump 204 is started to smoothly deliver the flavor liquid to the leakage cylinder 203, and then smoothly penetrates into the sponge sleeve 7 through the holes on the surface of the leakage cylinder 203. During the delivery process, the flexible and porous characteristics of the sponge sleeve 7 are used to smoothly coat the flavor liquid onto the tipping paper substrate. The laser-engraved fragrance guide area avoids damage to the engraved texture caused by hard contact, achieving a precise match between the fragrance substance and the engraved structure. Simultaneously, the rotating motor 304 drives the rotating disc 302 to rotate, causing the adjusting roller 303 to move smoothly within the arc-shaped sliding cavity 6 on the surface of the fixed disc 301. This allows for flexible adjustment of the conveying posture and tension of the coating and the substrate, ensuring smooth conveying of the laser-engraved substrate and the outer coating. Subsequently, the cylinder 11 is activated, driving the slider 9 to move along the slide groove 13 under the constraint of the positioning rod 14, simultaneously driving the pressing roller 10 to move, so that the substrate and the coating are tightly pressed between the pressing roller 10 and the support roller 12, completing the coating operation. During the processing, the camera 5 collects the conveying status of the substrate and the coating in real time and transmits the data to the control console 19. The control console 19 uses this data to control the start and stop of the rotating motor 304 and the rotation angle, and to fine-tune the position of the adjusting roller 303, ensuring the stability of both and guaranteeing the quality of the coating process.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
