[0002] A cigarette label is the trademark of a cigarette product and is one of the four major flat-printing collectibles in the world. During the production process of cigarette cases, local representative signs and production information, that is, cigarette labels, are usually printed on the surface of cigarette cases.

[0003] After the cigarette label printing is completed, the ink is difficult to dry in time. Therefore, it needs to be dried before forming. The traditional treatment method is to use hot air heating. However, the printed matter needs to be placed on a drying rack and clamped and positioned from its side. However, the clamping components at the bottom and side will still interfere with the printed matter, affecting the uniform contact between the hot air and the printed matter, making it difficult to heat evenly, resulting in different degrees of shrinkage or expansion of each part of the cigarette label, thereby generating internal stress and causing deformation phenomena such as warping and wrinkling of the cigarette label.

Specific embodiments

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0046] Embodiment 1: Please refer to Figures 1 to 7 , the present invention provides a technical solution: an energy-saving drying device for cigarette label printing, including a drying box 1, a sealing door 11, a heat pump drying system 12, a first fan 13 and a second fan 14. The sealing door 11 is movably installed on the surface of the drying box 1. The first fan 13 and the second fan 14 are respectively installed on both sides of the drying box 1. The heat pump drying system 12 is located on the side of the drying box 1 where the first fan 13 is installed. A circulation pipe 15 is installed on the second fan 14. One end of the circulation pipe 15 away from the second fan 14 is installed with a third fan 16. The third fan 16 is connected to the heat pump drying system 12 through a pipeline;

[0047] A positioning component, which is used to improve the drying effect and is fixedly installed in the inner cavity of the drying box 1;

[0048] A deformation component, which is used to improve the drying efficiency;

[0049] A uniform component, which is fixedly connected to the positioning component and is used to improve the drying effect;

[0050] A cleaning component, which is used for the maintenance of the device and is connected to the circulation pipe 15.

[0051] The positioning component includes two first fixing plates 2, which are respectively located on both sides of the inner cavity of the drying box 1. A second fixing plate 21 is arranged in the inner cavity of the first fixing plate 2, and the second fixing plate 21 is located between the two first fixing plates 2;

[0052] Negative pressure chambers 22 are fixedly installed at the bottoms of both the first fixing plate 2 and the second fixing plate 21. And the number of the negative pressure chambers 22 at the bottom of the second fixing plate 21 is two. Fourth blowers 24 are fixedly installed on both sides of the drying box 1. First negative pressure pipes 23 are fixedly installed on both sides of the air suction openings of the fourth blowers 24. The two first negative pressure pipes 23 are communicated with the negative pressure chambers 22 installed on the first fixing plate 2 and the second fixing plate 21 respectively;

[0053] Second negative pressure pipes 25 are fixedly installed on both the first fixing plate 2 and the second fixing plate 21. The second negative pressure pipes 25 are communicated with the first negative pressure pipes 23. One end of the second negative pressure pipe 25 far from the first negative pressure pipe 23 is fixedly installed with a transition hose 26. One end of the transition hose 26 far from the second negative pressure pipe 25 is fixedly installed with a support pipe 27;

[0054] On the lower side of the outer surface of the support pipe 27, four third negative pressure pipes 28 are fixedly installed, and they are evenly distributed on the outer surface of the support pipe 27. The support pipe 27 is communicated with the third negative pressure pipes 28. A cigarette label 29 is arranged at the top of the third negative pressure pipe 28;

[0055] A fixed frame 210 is fixedly sleeved on the outer surface of the second negative pressure pipe 25. A first servo motor 211 is fixedly installed on the surface of the fixed frame 210. The support pipe 27 is fixedly installed on the outer surface of the output shaft of the first servo motor 211 and is located inside the fixed frame 210.

[0056] A spacer 212 is fixedly installed inside the support pipe 27. The third negative pressure pipes 28 are located below the spacer 212. A wind guide chamber 213 is fixedly sleeved on one side of the support pipe 27. An air outlet 214 is arranged on the side of the support pipe 27 far from the wind guide chamber 213;

[0057] The top of the support pipe 27 is hollow. One end of the wind guide chamber 213 located inside the support pipe 27 is inclined upward;

[0058] The first negative pressure pipe 23 is a flexible pipe. The part of the first negative pressure pipe 23 located in the inner cavity of the drying box 1 is provided with an extra length. A sealing ring is arranged between the first negative pressure pipe 23 and the drying box 1;

[0059] The height of the third negative pressure pipe 28 gradually increases from the direction of the first blower 13 to the second blower 14. The distance between the lowest third negative pressure pipe 28 and the highest third negative pressure pipe 28 is half of the length of the inner cavity of the drying box 1.

[0060] Specifically, when in use, the cigarette label 29 needs to be placed flat on the top of the third negative pressure tube 28, and the four third negative pressure tubes 28 are located at the four corners of the bottom of the cigarette label 29. At this time, the cigarette label 29 will be supported by the support tube 27 and the four third negative pressure tubes 28. By starting the fourth fan 24, the first negative pressure tube 23, the second negative pressure tube 25, the transition hose 26 and the support tube 27 cooperate with each other, so that the third negative pressure tube 28 can generate negative pressure, thereby adsorbing the cigarette label 29 to achieve the fixation of the cigarette label 29. Compared with the traditional fixing method, the fixing method of the present invention can make the cigarette label 29 suspended in disguise, and the side will not be affected by the clamping, so that the upper surface of the cigarette label 29 can be evenly dried, and the area blocked by the bottom is smaller, thereby improving the drying effect.

[0061] When the cigarette labels 29 are fixed, the sealing door 11 needs to be closed and the sealing of the device is checked. Then, the heat pump drying system 12 is started to heat the air pressure, and the hot air is blown into the inner cavity of the drying box 1 through the first fan 13 to achieve the drying operation of the cigarette labels 29. The hot air is circulated through the second fan 14, the circulation pipe 15 and the third fan 16. Since the cigarette labels 29 on the same straight line are at different heights, the cigarette labels 29 can be unobstructed, increasing the contact area between them and the hot air and improving the drying efficiency.

[0062] Furthermore, hot air can be introduced into the inner cavity of the support tube 27 through the air guide chamber 213 to heat the overlapping portion of the support tube 27 and the cigarette label 29, thereby preventing the bottom of the support tube 27 from overlapping with the clamping structure and affecting the drying effect.

[0063] Example 2: Please refer to Figure 8 and Figure 9 The deformation component includes a clearance groove 3, which is opened on the surface of the fixed frame 210. A gearbox 31 is fixedly installed on the inner side of the fixed frame 210. The output shaft of the first servo motor 211 is fixedly connected to the input shaft of the gearbox 31;

[0064] A first rotating wheel 32 is fixedly mounted on the output shaft of the gearbox 31, a transmission belt 33 is transmission-connected to the outer surface of the first rotating wheel 32, a second rotating wheel 34 is transmission-connected to the side of the transmission belt 33 away from the first rotating wheel 32, and the second rotating wheel 34 is movably mounted on the fixed frame 210;

[0065] A gear 35 is fixedly installed in the middle of the second rotating wheel 34, an arc-shaped rack 36 is meshed on one side of the gear 35, a support plate 37 is fixedly installed on one end of the arc-shaped rack 36, and limit blocks 38 are movably installed on the upper and lower ends of the arc-shaped rack 36, and the limit blocks 38 are fixedly connected to the fixed frame 210;

[0066] The shape of the clearance groove 3 is arc-shaped, and the clearance groove 3 is adapted to the travel path of the circulation pipe 15.

[0067] On the basis of Embodiment 1, after the cigarette label 29 is preliminarily dried, starting the first servo motor 211 can drive the support tube 27 to rotate, so that the support tube 27 and the third negative pressure tube 28 drive the cigarette label 29 to turn by 90 degrees. At this time, the cigarette label 29 is preliminarily dried. Even when the cigarette label 29 is turned to a vertical state, ink dripping can be avoided. At the same time, when the cigarette label 29 is in a vertical state, it can be in more direct contact with the hot air, improving the drying efficiency, as Figure 8 and Figure 9 shown;

[0068] However, when the cigarette label 29 changes from a horizontal state to a vertical state, its weight is no longer supported by the third negative pressure tube 28 and the support tube 27 except being shared by the negative pressure, which easily affects its stability;

[0069] Under the speed change of the gearbox 31, the first runner 32 will rotate, thereby driving the transmission belt 33, so that the transmission belt 33 drives the second runner 34 to rotate. The second runner 34 can be used to drive the gear 35 to rotate, so that the gear 35 drives the arc-shaped rack 36 to drive, so that the support plate 37 moves below the cigarette label 29, and then supports the cigarette label 29 in a vertical state, improving the stability of the cigarette label 29.

[0070] Embodiment 3: Please refer to Figure 3 、 Figure 4 、 Figure 9 and Figure 10 , the uniform component includes an installation groove 4. The installation groove 4 is opened inside the drying box 1. A second servo motor 41 is fixedly installed on one side of the drying box 1. A bidirectional lead screw 42 is fixedly installed on the output shaft of the second servo motor 41. The bidirectional lead screw 42 is movably installed in the inner cavity of the installation groove 4;

[0071] One side of the outer surface of the bidirectional lead screw 42 is helically connected with a first nut 43. The first nut 43 is fixedly connected with the second fixing plate 21. A first driving groove 44 adapted to the first nut 43 is opened inside the drying box 1;

[0072] The side of the outer surface of the bidirectional lead screw 42 away from the first nut 43 is helically connected with a second nut 45. Both sides of the second nut 45 are fixedly installed with brackets 46. The two brackets 46 are respectively fixedly connected with the two first fixing plates 2. A second driving groove 47 adapted to the brackets 46 is opened inside the drying box 1.

[0073] During the hot air drying process, it is difficult to achieve absolute temperature uniformity. There are differences in the temperature at different positions inside the drying box. The temperature in the area close to the heat source or the air outlet is higher or lower, resulting in inconsistent drying degrees of different parts of the cigarette label;

[0074] In the operation of the above embodiment, during the drying process, by starting the second servo motor 41, the bidirectional lead screw 42 can be driven to rotate, so that the bidirectional lead screw 42 drives the first nut 43 and the second nut 45 to move. By using the first nut 43 and the second nut 45, the corresponding cigarette labels 29 on the first fixing plate 2 and the second fixing plate 21 can be driven to move left and right, so that the cigarette labels 29 will not always be in the low-temperature or high-temperature area, thereby improving the effect of uniform drying.

[0075] It should be noted that when setting the first negative pressure pipe 23, an extra length needs to be set to prevent the negative pressure bin 22 from pulling the first negative pressure pipe 23 when it moves. A slide rail can also be set between the negative pressure bin 22 and the drying box 1 to facilitate its movement.

[0076] Embodiment 4: Please refer to Figure 2 and Figure 12 , the cleaning component includes an elastic column 5 fixedly connected to the inner cavity of the circulation pipe 15. The other end of the elastic column 5 is fixedly connected with a scraping ring 51, and the scraping ring 51 is movably installed in the inner cavity of the circulation pipe 15.

[0077] A dust suction system 52 is arranged on one side of the drying box 1. A dust suction pipe 53 is fixedly installed at the dust suction port of the dust suction system 52. One end of the dust suction pipe 53 away from the dust suction system 52 is fixedly connected with the circulation pipe 15, and a valve 54 is installed at one end of the dust suction pipe 53 close to the circulation pipe 15.

[0078] The ink used in cigarette label printing contains a large amount of VOCs. The VOCs volatilized during the drying process and the residual ink are all flammable substances. When they accumulate to a certain concentration in the drying box or ventilation duct, it will not only affect the hot air circulation efficiency, but may even cause a fire or explosion when encountering an open fire or high temperature.

[0079] On the basis of Embodiment 1, when the drying operation is in progress, due to the action of the wind pressure, the scraping ring 51 will move. At this time, the elastic column 5 is in a stretched state. When the drying operation is completed, the elastic column 5 will drive the scraping ring 51 to reset, so as to scrape off the VOCs and residual ink accumulated in the inner cavity of the circulation pipe 15. Then, the valve 54 is opened and the dust suction system 52 is started. Under the action of negative pressure, the scraped VOCs and residual ink will be conducted to the dust suction system 52 through the dust suction pipe 53 for recovery, making the maintenance more convenient.

[0080] It should be noted that when setting the dust suction pipe 53, it can be arranged between the two scraping rings 51, so that the dust suction pipe 53 can be close to the position where the VOCs and residual ink are scraped off.

[0081] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
