Description

Technical Field

[0001] This invention relates to the field of printing equipment, and more particularly to printing production equipment for embossed spliced ​​paper. Background Technology

[0002] Tipping paper is a special type of paper used to connect cigarette filters to the cigarette pack, typically requiring printing, perforation, and embossing processes. With rising living standards and increasing demand for personalization, consumers are placing higher demands on the taste experience of cigarettes. Flavored tipping papers, especially those with multiple flavors, can provide consumers with a richer and more unique sensory experience without altering the original flavor of the tobacco, and are therefore widely welcomed by the market.

[0003] In existing technologies, the production of scented tipping paper typically involves scenting the entire paper strip, such as by impregnation or spraying to evenly coat the paper surface with fragrance substances. While this method achieves scenting, it suffers from the following problems: First, the scent is singular, making it impossible to differentiate flavors in different areas of the same tipping paper; second, the fragrance substances are exposed on the paper surface, making them prone to evaporation and dissipation, resulting in a short-lasting scent; third, different flavors usually require additional labeling on the packaging, making it impossible to visually distinguish them from the tipping paper itself. Furthermore, traditional embossing equipment has limited functionality and cannot meet the complex process requirements of precise scenting and curing of specific areas after embossing. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by providing a printing production equipment for embossed spliced ​​paper.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A printing production equipment for embossed tipped paper includes a side plate. A winding roller, a take-up roller, a guide roller, and an embossing roller are rotatably connected to the side of the side plate. A groove is also provided on the side of the side plate, within which an adjusting roller is slidably disposed. The embossing roller includes an upper pressure roller and a lower pressure roller. Following the paper's running direction, a micro-spraying device, a first set of infrared drying devices and a hot air drying device, a flavoring identification device, and a second set of infrared drying devices and a hot air drying device are sequentially arranged. The micro-spraying device is used to spray food-grade hydrophobic material onto the ridge surface.

[0006] In the above-mentioned printing production equipment for embossed splicing paper, the micro-spraying device includes a micro-spraying pipe, the two sides of which are fixedly connected to the side plate through connecting blocks, and multiple micro-spraying heads are fixedly provided on the side of the micro-spraying pipe facing the splicing paper.

[0007] In the above-mentioned printing production equipment for embossed tipping paper, the infrared drying device includes a lampshade, which is fixedly connected to the side of the side plate, and multiple infrared lamps are fixedly installed inside the lampshade.

[0008] In the above-mentioned printing production equipment for embossed tipping paper, the hot air drying device includes a positive pressure air box, which is fixedly connected to the side of the side plate and located above the tipping paper tape. The top surface of the positive pressure air box is provided with an air inlet, and a heating tube is fixedly provided below the air inlet. A fixing column is fixedly provided below the heating tube. The two ends of the fixing column are respectively fixedly connected to the side of the positive pressure air box. A fan is rotatably provided on the upper surface of the fixing column, and the fan is located between the fixing column and the heating tube.

[0009] In the above-mentioned printing production equipment for embossed and spliced ​​paper, the hot air drying device further includes a negative pressure air box, which is fixedly connected to the side of the side plate and located below the corresponding position of the positive pressure air box. A fixed column is fixedly provided inside the negative pressure air box, and the two ends of the fixed column are fixedly connected to the side of the negative pressure air box respectively. A fan is rotatably provided on the lower surface of the fixed column, and an air outlet is also provided on the bottom surface of the negative pressure air box.

[0010] In the above-mentioned printing production equipment for embossed and tipped paper, the flavoring identification device includes a storage box, a scanning camera is fixedly installed on the left side of the bottom surface of the storage box, and multiple nozzles are fixedly arranged at other positions on the bottom surface of the storage box. The nozzles are used to spray flavoring substances into the corresponding embossing.

[0011] In the above-mentioned printing production equipment for embossed tipping paper, the nozzle includes a first nozzle and a second nozzle. The first nozzle is located to the left of the second nozzle. The first nozzle is used to spray fragrance substances into the corresponding embossing, and the second nozzle is used to spray transparent water-based varnish to lock in the fragrance substances and reduce their dissipation.

[0012] In the above-mentioned printing production equipment for embossed tipping paper, the surface of the embossing roller is engraved with a groove-shaped pattern, and the bottom of the groove is provided with multiple micro-holes.

[0013] Compared with existing technologies, the advantages of this printing production equipment are: 1. This invention constructs a complete "embossing-hydrophobic treatment-drying-precise fragrance addition-fragrance locking" production line by sequentially setting a micro-spraying device, a drying device, and a flavoring identification device after the embossing roller. First, the micro-spraying device sprays a hydrophobic material onto the raised ridge surface formed by embossing and then dries it, creating differentiated hydrophilic / hydrophobic regions on the paper surface. This provides a physical boundary for the subsequent precise spreading and penetration of fragrance substances only within the embossing grooves, effectively preventing the mutual penetration and diffusion between different fragrances. 2. This invention utilizes a flavoring recognition device that employs a scanning camera to identify embossed patterns. Multiple nozzles then precisely spray different flavoring substances onto the corresponding embossed grooves based on the identified pattern information. This allows for the production of multiple flavors on a single sheet of packaging paper, greatly enriching the product's taste and personalization. Consumers can directly distinguish between different flavors through the visible embossed patterns, making it intuitive and convenient. 3. This invention, by setting a second nozzle, immediately sprays a layer of transparent water-based varnish after spraying the fragrance substance, forming a protective film. This varnish effectively seals the fragrance substance within the embossed grooves, significantly slowing down the evaporation and dissipation rate of the fragrance, and extending the fragrance retention time and shelf life of the tipping paper.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0018] Reference Figure 1-6 This invention provides a printing production device for embossed tipping paper, comprising two parallel side plates 1 serving as the supporting foundation for the entire device. Rotatably connected to the side plates 1 are unwinding rollers 2 for unwinding raw paper tape, winding rollers 3 for winding finished paper tape, and multiple steering rollers 5 for guiding and changing the direction of the paper tape. Vertical grooves 6 are also formed on the side plates 1, within which adjusting rollers 4 are slidably disposed for adjusting the tension and running path of the paper tape. An embossing roller 7 includes an upper pressure roller 701 and a lower pressure roller 702 that cooperate with each other, used to emboss the desired pattern on the paper tape. Specifically, the surface of the embossing roller 7 is engraved with a groove-shaped pattern, and the bottom of the groove has multiple micropores. These micropores help to expel air during the embossing process, making the embossed ridges clearer and fuller, and simultaneously forming micron-level indentations during embossing, enhancing the adhesion of subsequent coatings.

[0019] Along the direction of paper movement, after the embossing roller 7, are arranged in sequence: micro-jet printing device 8, first set of infrared drying device 9 and hot air drying device 10 (used in combination), flavoring identification device 11, second set of infrared drying device 9 and hot air drying device 10.

[0020] The micro-spraying device 8 includes multiple micro-spray tubes 801 spanning the width of the paper tape, with both ends fixed to the side plates 1 on both sides by connecting blocks. Multiple micro-nozzles 802 are evenly distributed on the side of the micro-spray tubes 801 facing the embossed splicing paper. These micro-nozzles 802 are used to precisely spray a layer of food-grade hydrophobic material onto the ridged surface formed by the embossing. Since the embossed ridges are the highest points of the paper tape, the micro-nozzles 802 can accurately cover the top and sides of the ridges with the hydrophobic material without it flowing into the bottom of the grooves. Thus, after subsequent drying, the surface of the paper tape forms a hydrophilic groove area and a hydrophobic ridge area.

[0021] The infrared drying device 9 includes a lampshade 901, which is fixed to the side plate 1, and multiple infrared lamps 902 are installed side by side inside. The infrared rays emitted by the infrared lamps 902 can penetrate the coating and heat it from the inside, causing the hydrophobic material or varnish to cure quickly.

[0022] The hot air drying device 10 consists of a positive pressure air box 1001 and a negative pressure air box 1002, located on the upper and lower sides of the paper tape respectively and positioned opposite each other. The positive pressure air box 1001 is located above the paper tape, with an air inlet 1006 on its top surface for connecting to an external air source. A heating tube 1003 is installed below the air inlet 1006 to heat the incoming air. A fixing column 1004 is horizontally fixed inside the positive pressure air box 1001, and a fan 1005 is rotatably mounted on the upper surface of the fixing column 1004. The fan 1005 is located below the heating tube 1003 and is used to evenly blow the heated air onto the surface of the paper tape. The negative pressure air box 1002 is located below the paper tape, also with a horizontally fixed fixing column 1004 inside. A fan 1005 is rotatably mounted on the lower surface of the fixing column 1004, and an air outlet 1007 is opened on the bottom surface of the negative pressure air box 1002. During operation, the upper fan 1005 blows hot air downwards to dry the coating on the paper tape and remove moisture at the same time; the lower fan 1005 generates negative pressure by rotating, which draws the hot air and moisture passing through the paper tape into the negative pressure air box 1002 and discharges it from the air outlet 1007, forming an effective hot air circulation, which improves drying efficiency and uniformity.

[0023] The flavoring identification device 11 is crucial for producing multi-flavored tipping paper. It includes a storage box 1102, internally divided into multiple independent chambers for storing different flavoring substances (such as mint, fruit, etc.) and transparent water-based varnish. Multiple scanning cameras 1101 are fixedly installed on the far left side of the bottom surface of the storage box 1102 (in the paper's running direction, i.e., the front end). At other locations on the bottom surface of the storage box 1102, multiple nozzles are arranged sequentially along the paper's running direction, specifically including a first nozzle 1103 and a second nozzle 1104. There are multiple first nozzles 1103, each connected to a chamber within the storage box 1102 that stores a specific flavoring substance. The second nozzle 1104 is located behind the first nozzles 1103 and connected to the chamber storing the transparent water-based varnish. During operation, the scanning cameras 1101 first perform a high-speed scan of the embossed paper strip running below them, identifying and locating different embossed pattern areas on the paper strip. Based on the information fed back by the scanning camera 1101, the control system precisely controls the corresponding first nozzle 1103 to spray a specific flavor of fragrance substance into the corresponding embossed groove. Subsequently, the second nozzle 1104 sprays a layer of transparent water-based varnish onto the entire area or a specific area that has been sprayed with fragrance substance, sealing the fragrance substance within the groove.

[0024] Working principle: First, the paper strip is released from the unwinding roller 2, guided by the turning roller 5 and adjusting roller 4, and then enters the embossing roller 7. It is pressed by the upper pressure roller 701 and lower pressure roller 702, forming a three-dimensional pattern of ridges and grooves on the paper strip surface. The embossed paper strip then enters below the micro-spraying device 8, where the micro-spraying head 802 sprays a food-grade hydrophobic material onto the ridge surface. Subsequently, the paper strip passes sequentially through the first set of infrared drying devices 9 and hot air drying devices 10, rapidly drying and curing the hydrophobic material to form clear hydrophilic / hydrophobic area boundaries. Next, the processed paper strip enters the flavoring device 11. The scanning camera 1101 identifies the embossed pattern, and the control system instructs the first spraying head 1103 to precisely spray the corresponding flavoring substance into the designated embossed grooves. Immediately afterward, the second spraying head 1104 sprays a layer of transparent water-based varnish onto the flavored area. Finally, the paper strip passes through the second set of infrared drying devices 9 and hot air drying devices 10, rapidly drying the varnish to form a strong protective film that locks in the flavor. Finally, the finished spliced ​​paper, having completed all the processes, is wound up by take-up roller 3.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
