Description

Technical Field

[0001] The present application belongs to the technical field of cigarette tipping processing equipment, and in particular relates to a device for drying the glue-coated surface of cigarette tipping paper. Background Art

[0002] Cigarettes are made by drying tobacco, cutting it into shreds, and then rolling it into cylindrical strips about 120 mm long and 10 mm in diameter. To smoke, one end of the tobacco is lit, and the smoke produced by the incomplete combustion is inhaled through the other end. Currently, cigarette production often requires tipping paper, the wrapping paper that connects the cigarette to the mouthpiece. Originally, tipping paper was also called tipping paper because of its pinewood-like appearance. Tipping paper emerged with the advent of filter-tipped cigarettes, and its specifications are determined by the specific requirements of the cigarette.

[0003] In the production process of tipping paper base paper, in order to ensure printing quality, it is necessary to dry the paper after gluing. To ensure printing quality, the patent with publication number CN219568468U discloses a tipping paper drying device, including a drying box, in which a first roller, a second roller and a third roller are rotated and matched. The drying box is equipped with tipping paper corresponding to the first roller, the second roller and the third roller. The upper and lower sides of the drying box are equipped with heating plates. The drying box is equipped with two heat-conducting clamps. Heat-conducting rods are fixedly connected between the two heat-conducting clamps and the two heating plates. An exhaust fan is fixedly connected to the side of the drying box, and the air inlet of the exhaust fan is connected to the drying box.

[0004] In the above patent, air outlets are provided on the roller to air-dry the binding paper through the air outlets. Although the drying effect can be achieved, the air outlets are evenly distributed on the roller, and the edges and inner walls of the binding paper are directly dried together, which easily leads to the problem of loosening of the edges after drying, and needs to be improved. Utility Model Content

[0005] The purpose of this application is to provide a device for drying the glue-coated surface of cigarette tipping paper, which can solve the above problems.

[0006] The purpose of this application is to provide a device for drying the glue-coated surface of cigarette tipping paper, comprising:

[0007] The drying box has a drying space inside, an inlet and an outlet on both sides of the drying box, and a heating device is provided in the drying space for heating the drying space;

[0008] The drying mechanism is arranged in the drying space and is used to guide and dry the tipping paper. The drying mechanism includes:

[0009] a first drying roller;

[0010] a second drying roller, disposed on one side of the first drying roller;

[0011] An air delivery device, comprising an exhaust fan, an air pipe connected to the first drying roller and the second drying roller, and air vents provided on the first drying roller and the second drying roller;

[0012] The ventilation holes on the first drying roller are located on both sides of the first drying roller, and the ventilation holes on the second drying roller are located in the middle of the second drying roller.

[0013] The aforementioned drying device for the glued surface of cigarette plugging paper uses a drying chamber within a drying box to ensure that the plugging paper is dried in a closed and controllable environment. An inlet and outlet are provided on either side of the drying chamber to facilitate the continuous entry and exit of the plugging paper. A heating device is provided within the drying chamber to increase the temperature of the drying chamber and accelerate the drying process. The heating device can be an electric heating wire or other existing heating device. The drying mechanism includes a first drying roller and a second drying roller, which work together to dry the plugging paper in sections. Both the first drying roller and the second drying roller are provided with vents for admitting dry gas. The gas supply device includes an exhaust fan, an air pipe, etc., to ensure that the dry gas is evenly and stably supplied to the two drying rollers.

[0014] The first drying roller has ventilation holes on its sides, primarily drying the edges of the tipping paper. The second drying roller has ventilation holes in its center, primarily drying the center. By drying the edges first and then the center, loosening of the edges caused by overly rapid drying is avoided. This allows for a more uniform shrinkage rate during the drying process, thereby improving product quality. This continuous and stable drying process ensures stable and consistent product quality. By optimizing the drying process, quality issues such as deformation and cracking of the tipping paper caused by improper drying are reduced.

[0015] Furthermore, the drying mechanism further comprises a third drying roller and a fourth drying roller, and ventilation holes are provided in the middle and on both sides of the third drying roller and the fourth drying tube.

[0016] The third and fourth drying rollers feature ventilation holes located in the center and on both sides, ensuring more uniform and comprehensive airflow during the subsequent drying process. On the third drying roller, the central and side ventilation holes work together to further dry the center and edges of the paper. The fourth drying roller, serving as the final drying stage, also features ventilation holes that ensure the paper reaches an ideal dry state before leaving the drying mechanism, helping to improve drying efficiency and quality consistency. This collaborative approach shortens drying time for the paper and increases production efficiency.

[0017] Further: the drying mechanism also includes:

[0018] There are two guide clamps, and a gap is provided between the two guide clamps for the tipping paper to pass through;

[0019] A support plate, disposed in the drying space and used to support the guide splint;

[0020] Wherein, a heating plate is provided on the guide clamping plate for heating the guide clamping plate.

[0021] Two guide splints are provided, with a gap between them for the tipping paper to pass through. The width of this gap can be adjusted according to the thickness of the tipping paper to ensure smooth passage of the tipping paper. The main function of the guide splints is to guide the tipping paper along a predetermined path within the drying space. They also serve as a heat conduction medium, transferring heat from the heating plate to the tipping paper and ironing the tipping paper. A support plate is provided within the drying space to support and guide the splints. The guide splints are equipped with a heating plate, which transfers heat to the guide splints by heat conduction, thereby heating the tipping paper. The synergistic effect of the heating plate and the guide splints can accelerate the evaporation and discharge of moisture from the tipping paper, thereby improving drying efficiency.

[0022] Furthermore, the guide clamp is arranged to be tilted, and its tilt angle is the same as the guide direction of the tipping paper.

[0023] The guide plates are tilted, with their angle aligned with the direction of the tipping paper. This helps the paper flow more smoothly through the drying mechanism under the influence of gravity, reducing damage or deformation caused by friction and resistance. Furthermore, the tilted setting ensures that the paper is more evenly heated during the drying process, improving drying uniformity and efficiency.

[0024] Furthermore, the support plate is vertically arranged, and the support plate and the guide clamping plate are detachably connected, and the support plate is a telescopic plate, which is fixed by bolts.

[0025] The vertical positioning of the support plates ensures a stable position within the drying chamber, providing reliable support for the guide plates and minimizing deformation or tilting due to gravity. This ensures a consistent gap between the guide plates, ensuring smooth passage of tipping paper. The support plates and guide plates are connected by removable bolts or snap-fit ​​connections, facilitating maintenance and replacement of the drying mechanism. The support plates utilize a telescopic design, allowing their length to be adjusted to vary the spacing between the guide plates, accommodating tipping paper of varying widths.

[0026] Furthermore, the first drying roller, the second drying roller, the third drying roller and the fourth drying roller are distributed in an upper and lower position, and the guide clamp is located between the second drying roller and the third drying roller.

[0027] Placing the four drying rollers one above the other fully utilizes the height of the drying chamber, helping to reduce airflow resistance and energy consumption during the drying process, thereby improving drying efficiency. A guide plate is placed between the second and third drying rollers to ensure that the tipping paper is stably guided and supported after the initial drying process by the first two drying rollers before entering the more advanced drying stages. The guide plate also prevents deformation or tearing of the tipping paper due to uneven tension during the drying process.

[0028] The beneficial effects of this application are:

[0029] 1. By drying the edges of the tipping paper first and then the middle part, the loosening problem caused by too fast drying of the edges is avoided, and the shrinkage rate of the tipping paper can be maintained more uniformly during the drying process, thereby improving the quality of the product;

[0030] 2. Through continuous and stable drying of the tipping paper, the stability and consistency of product quality are ensured. By optimizing the drying process, quality problems such as deformation and cracking of the tipping paper caused by improper drying are reduced.

[0031] 3. Through the synergistic effect of the heating plate and the guiding clamping plate, the evaporation and discharge of moisture inside the tipping paper can be accelerated, thereby improving the drying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The device for drying the glue-coated surface of cigarette tipping paper provided in the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios.

[0037] Example 1:

[0038] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a device for drying the glue-coated surface of cigarette tipping paper, comprising:

[0039] The drying box 100 has a drying space 110 therein, with an inlet 120 and an outlet 130 provided on both sides thereof, and a heating device 140 provided in the drying space 110 for heating the drying space 110;

[0040] The drying mechanism is provided in the drying space 110 and is used to guide and dry the tipping paper. The drying mechanism includes:

[0041] First drying roller 200;

[0042] The second drying roller 210 is provided on one side of the first drying roller 200;

[0043] The air delivery device 300 includes an exhaust fan 310, an air pipe 320 connected to the first drying roller 200 and the second drying roller 210, and air vents 330 provided on the first drying roller 200 and the second drying roller 210;

[0044] The vent holes 330 on the first drying roller 200 are located on both sides of the first drying roller 200 , and the vent holes 330 on the second drying roller 210 are located in the middle of the second drying roller 210 .

[0045] In some implementations of the embodiments of this application, Figure 1As shown, the aforementioned device for drying the glued surface of cigarette tipping paper utilizes a drying chamber 110 within a drying box 100, ensuring that the tipping paper is dried in a closed and controllable environment. An inlet 120 and an outlet 130 are provided on either side of the drying chamber to facilitate the continuous entry and exit of the tipping paper. A heating device 140 is also provided within the drying chamber to increase the temperature of the drying chamber 110 and accelerate the drying process. The heating device 140 can be a heating wire or other existing heating device. The drying mechanism includes a first drying roller 200 and a second drying roller 210, which work together to dry the tipping paper in sections. Both the first drying roller 200 and the second drying roller 210 are provided with vents 330 for admitting dry gas. The gas supply device 300, including an exhaust fan 310 and an air pipe 320, ensures that the dry gas is evenly and stably supplied to the two drying rollers.

[0046] The first drying roller 200 has ventilation holes 330 located on its sides, primarily drying the edges of the tipping paper. The second drying roller 210 has ventilation holes 330 located in its center, primarily drying the center of the tipping paper. By drying the edges first and then the center, loosening of the edges caused by overly rapid drying is avoided. This allows the tipping paper to maintain a more uniform shrinkage rate during the drying process, thereby improving product quality. This continuous and stable drying process ensures stable and consistent product quality. By optimizing the drying process, quality issues such as deformation and cracking of the tipping paper caused by improper drying are reduced.

[0047] In addition, the drying mechanism further includes a third drying roller 220 and a fourth drying roller 230. Ventilation holes 330 are provided in the middle and on both sides of the third drying roller 220 and the fourth drying tube.

[0048] The ventilation holes 330 on both the third drying roller 220 and the fourth drying roller 230 are located in the center and on both sides, ensuring that the tipping paper receives more uniform and comprehensive airflow during the subsequent drying process. The ventilation holes 330 on the third drying roller 220 work in tandem to further dry the center and edges of the tipping paper. The fourth drying roller 230, serving as the final drying step, also features ventilation holes 330 that ensure the tipping paper reaches an ideal dry state before leaving the drying mechanism, helping to improve drying efficiency and quality consistency. This collaboration helps shorten the drying time of the tipping paper and enhance production efficiency.

[0055] In an embodiment of the present application, two guide splints 400 are provided, with a gap between them for the tipping paper to pass through. The width of this gap can be adjusted according to the thickness of the tipping paper to ensure that the tipping paper can pass smoothly. The main function of the guide splints 400 is to guide the tipping paper to move along a predetermined path within the drying space 110. At the same time, they can also serve as a heat conduction medium, transferring heat from the heating plate 600 to the tipping paper, and can also iron the tipping paper. The support plate 500 is provided in the drying space 110 to support and guide the splints 400. A heating plate 600 is provided on the guide splint 400, which transfers heat to the guide splint 400 by heat conduction, thereby heating the tipping paper. The synergistic effect of the heating plate 600 and the guide splint 400 can accelerate the evaporation and discharge of moisture inside the tipping paper, thereby improving the drying efficiency.

[0056] Furthermore, the guide clamping plate 400 is tilted, and its tilt angle is the same as the guide direction of the tipping paper.

[0057] In some embodiments of the present application, the guide plate 400 is tilted, with its angle aligning with the guide direction of the tipping paper. This helps the tipping paper pass through the drying mechanism more smoothly under the influence of gravity, reducing damage or deformation of the tipping paper caused by friction and resistance. Furthermore, the tilted arrangement ensures that the tipping paper is more evenly heated during the drying process, improving drying uniformity and efficiency.

[0061] In the embodiment of the present application, the vertical arrangement of the support plates 500 ensures that they occupy a stable position within the drying space 110, providing reliable support for the guide plates 400 and reducing deformation or tilting due to gravity. This ensures that the gap between the guide plates 400 remains consistent, ensuring the smooth passage of tipping paper. The support plates 500 and guide plates 400 are connected by a removable connection, such as a bolt connection or a snap connection, to facilitate maintenance and replacement of the drying mechanism. The support plates 500 utilize a telescopic design, and their length can be adjusted to change the spacing between the guide plates 400, thereby accommodating tipping paper of varying widths.
