Description

[0002] Cigarette labels are the trademarks of cigarette products and are one of the four major graphic print collections in the world. During the production process of cigarette boxes, the local representative logo and production information, namely the cigarette labels, are usually printed on the surface of the cigarette boxes.

[0003] After the cigarette label is printed, the ink is difficult to dry in time, so it needs to be dried before molding. The traditional processing method is to use hot air heating, but the printed part needs to be placed on a drying rack and then clamped and positioned from its side. However, the clamping components at the bottom and sides will still interfere with the printed part, affecting the uniform contact between the hot air and the printed part, making it difficult to heat evenly, causing different parts of the cigarette label to shrink or expand to different degrees, thereby generating internal stress and causing deformation of the cigarette label such as warping and wrinkling.

DETAILED DESCRIPTION

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

[0046] Example 1: Please refer to Figures 1 to 7 The present invention provides a technical solution: an energy-saving drying device for cigarette label printing, comprising a drying box 1, a sealed door 11, a heat pump drying system 12, a first fan 13 and a second fan 14, wherein the sealed door 11 is movably mounted on the surface of the drying box 1, the first fan 13 and the second fan 14 are respectively mounted 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 mounted, a circulation pipe 15 is mounted on the second fan 14, a third fan 16 is mounted on one end of the circulation pipe 15 away from the second fan 14, and 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] Deformation component, the deformation component 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 is used for the maintenance of the device and is connected to the circulation pipe 15 .

[0051] The positioning assembly 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 provided 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 bins 22 are fixedly installed at the bottom of the first fixed plate 2 and the second fixed plate 21, and the number of negative pressure bins 22 at the bottom of the second fixed plate 21 is two, fourth fans 24 are fixedly installed on both sides of the drying box 1, and first negative pressure pipes 23 are fixedly installed on both sides of the air outlet of the fourth fan 24, and the two first negative pressure pipes 23 are respectively connected to the negative pressure bins 22 installed on the first fixed plate 2 and the second fixed plate 21;

[0053] A second negative pressure pipe 25 is fixedly mounted on both the first fixing plate 2 and the second fixing plate 21. The second negative pressure pipe 25 is connected to the first negative pressure pipe 23. A transition hose 26 is fixedly mounted on one end of the second negative pressure pipe 25 away from the first negative pressure pipe 23. A support pipe 27 is fixedly mounted on one end of the transition hose 26 away from the second negative pressure pipe 25.

[0054] A third negative pressure tube 28 is fixedly installed on the lower side of the outer surface of the support tube 27. The number of the third negative pressure tubes 28 is four and they are evenly distributed on the outer surface of the support tube 27. The support tube 27 is connected to the third negative pressure tube 28. A cigarette mark 29 is set on the top of the third negative pressure tube 28.

[0055] The outer surface of the second negative pressure tube 25 is fixedly sleeved with a fixing frame 210 , the surface of the fixing frame 210 is fixedly mounted with a first servo motor 211 , and the support tube 27 is fixedly mounted on the outer surface of the output shaft of the first servo motor 211 and is located inside the fixing frame 210 .

[0056] A spacer 212 is fixedly installed inside the support tube 27, and the third negative pressure tube 28 is located below the spacer 212. An air guide bin 213 is fixedly sleeved on one side of the support tube 27, and an air outlet 214 is provided on the side of the support tube 27 away from the air guide bin 213.

[0057] The top of the support tube 27 is hollow, and the air guide chamber 213 and one end inside the support tube 27 are inclined upward;

[0058] The first negative pressure pipe 23 is a hose, and the portion of the first negative pressure pipe 23 in the inner cavity of the drying box 1 is provided with extra length, and a sealing ring is provided 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 first fan 13 to the second fan 14 , and the distance between the lowest third negative pressure pipe 28 and the highest third negative pressure pipe 28 is half 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 Fig. 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 Example 1, after the cigarette label 29 is preliminarily dried, the first servo motor 211 is started to 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 over 90 degrees. At this time, the cigarette label 29 is preliminarily dried, and even if the cigarette label 29 is turned over and in a vertical state, it can avoid ink dripping. At the same time, the cigarette label 29 in a vertical state can further directly contact with the hot air, thereby improving the drying efficiency. Figure 8 and Fig. 9 As shown;

[0068] However, when the cigarette label 29 changes from a horizontal state to a vertical state, its weight is not only shared by the negative pressure, but is no longer supported by the third negative pressure tube 28 and the support tube 27, which may affect its stability.

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

[0070] Example 3: Please refer to Figure 3 , Figure 4 , Fig. 9 and Fig.10 The uniform component includes a mounting groove 4, which 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 mounting groove 4;

[0071] A first screw sleeve 43 is spirally connected to one side of the outer surface of the bidirectional lead screw 42, and the first screw sleeve 43 is fixedly connected to the second fixing plate 21. A first driving groove 44 adapted to the first screw sleeve 43 is provided inside the drying box 1;

[0072] A second screw sleeve 45 is spirally connected to the side of the outer surface of the bidirectional screw 42 away from the first screw sleeve 43, and brackets 46 are fixedly installed on both sides of the second screw sleeve 45. The two brackets 46 are respectively fixedly connected to the two first fixed plates 2, and a second driving groove 47 adapted to the bracket 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 temperature at different locations in the drying box. The temperature near the heating source or the air outlet is higher or lower, resulting in inconsistent drying degrees at different parts of the cigarette label.

[0074] In the operation of the above embodiment, during the drying process, the bidirectional lead screw 42 can be driven to rotate by starting the second servo motor 41, so that the bidirectional lead screw 42 drives the first screw sleeve 43 and the second screw sleeve 45 to move, and the first screw sleeve 43 and the second screw sleeve 45 can drive the corresponding cigarette labels 29 on the first fixing plate 2 and the second fixing plate 21 to move left and right, so that the cigarette labels 29 will not be always 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 excess length needs to be set to prevent the first negative pressure pipe 23 from being pulled when the negative pressure bin 22 moves. A slide rail can also be set between the negative pressure bin 22 and the drying box 1 to facilitate their movement.

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

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

[0078] The ink used for 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, they will not only affect the efficiency of hot air circulation, but may even cause fire or explosion when encountering open flames or high temperatures.

[0079] On the basis of Example 1, when the drying operation is in progress, the scraper ring 51 will move due to the effect of wind pressure, and the elastic column 5 is in a stretched state at this time. When the drying operation is completed, the elastic column 5 will drive the scraper ring 51 to reset, so that the VOCs accumulated in the inner cavity of the circulation pipe 15 and the residual ink can be scraped off, and then the valve 54 is opened and the dust collection system 52 is started. Under the effect of negative pressure, the scraped VOCs and residual ink will be transferred to the dust collection system 52 through the dust collection pipe 53 for recovery, making maintenance more convenient;

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

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