DETAILED DESCRIPTION
[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
[0025] As shown in the drawings, one embodiment of the present application proposes a high-efficiency drying device for cigarette label printing, which comprises: Figures 1-7
[0026] The transmission seat 1 is rotatably penetrated by the transmission roller 2 at both ends, and the transmission belt 3 is arranged on the two transmission rollers 2, preferably, one of the transmission rollers 2 is connected with the motor arranged on the transmission seat 1, the motor works to drive the transmission of the transmission belt 3, the transmission surface of the transmission belt 3 is arrayed with a plurality of through holes 4, the drying cover 5 is arranged on the transmission seat 1, two material passing grooves are arranged on the drying cover 5, and the two material passing grooves are respectively located at the two ends of the transmission direction, the cigarette box after printing is placed on the transmission belt 3, and the transmission belt 3 will transmit the cigarette box through the drying cover 5;
[0027] The drying mechanism 6 comprises an air pipe 601 arranged on the conveying seat 1 and located in the drying cover 5, a plurality of U-shaped pipes 602 are arrayed and communicated on the air pipe 601 along the length direction of the air pipe 601, the upper conveying surface of the conveying belt 3 is sequentially and movably penetrated through the plurality of U-shaped pipes 602, the inner walls on the upper and lower sides of the U-shaped pipes 602 are both arrayed and communicated with a plurality of spray pipes 603, the air pipe 601 is communicated with a first conveying pipe 604, the end of the first conveying pipe 604 is communicated with a heating fan 605, when the cigarette case is placed on the conveying belt 3 for conveying, the heating fan 605 works to suck and heat the air outside, the heated hot air is conveyed into the air pipe 601 through the first conveying pipe 604, the hot air in the air pipe 601 is further distributed into the plurality of U-shaped pipes 602, and finally sprayed out from the plurality of spray pipes 603, the hot air sprayed out from the plurality of spray pipes 603 located on the upper side blows the top of the cigarette case, the hot air sprayed out from the plurality of spray pipes 603 located on the lower side blows the bottom of the cigarette case through the through hole 4 on the conveying belt 3, so that the upper and lower sides of the cigarette case are both blown by the hot air, and the drying efficiency is further improved, preferably, the hot air sprayed out from the spray pipe 603 is not high-pressure air flow, at the same time, the air pressure on the lower side is smaller than that on the upper side due to the partial blockage of the conveying belt 3, so that the cigarette case is not caused to fly, the blowing on the upper and lower sides can not only ensure that the cigarette case is effectively dried by the hot air, but also improve the drying efficiency, and the requirement of rapid drying on the high-speed printing production line is effectively met.
[0028] In the scheme, the plurality of U-shaped pipes 602 are arranged, the spray pipes 603 are arrayed and communicated on the upper and lower sides of the U-shaped pipes 602, the upper conveying surface of the conveying belt 3 is conveyed through the blank area in the middle of the U-shaped pipes 602, and the cigarette case is blown and dried from the upper and lower sides by means of the through hole 4 arranged on the conveying belt 3, so that the requirement of rapid drying on the high-speed printing production line is effectively met, and the practicability is improved.
[0029] As shown in Figure 4 In some embodiments, the inner top wall of the drying cover 5 is arrayed with a plurality of UV curing lamps 7, and the plurality of UV curing lamps 7 are staggered with the plurality of U-shaped pipes 602, the UV curing lamps 7 emit ultraviolet light, the ultraviolet light directly acts on the photosensitive resin in the ink to make it quickly cured, and the UV curing lamps 7 cooperate with the double action of the hot air blowing to significantly improve the drying speed and adapt to the requirement of the high-speed printing production line.
[0030] As shown in Figure 3As shown in the drawings, in some embodiments, the transmission seat 1 is provided with a limiting mechanism 8, which is used to prevent the cigarette box from deviating under the action of the air flow. Although the cigarette box will not fly under the blowing of the air flow on the upper and lower sides, it may sometimes deviate slightly left and right. By setting the limiting mechanism 8 to limit the transmission of the cigarette box, it will not deviate during the drying process, ensuring the positioning of the transmission of the cigarette box, so as to facilitate the subsequent processing of the cigarette box, thereby improving the practicability.
[0031] As shown in the drawings, Figure 2 In some embodiments, the limiting mechanism 8 includes a sliding rod 801 connected to the transmission seat 1, two limiting plates 802 are slidably arranged on the sliding rod 801, a bidirectional screw rod 803 is rotatably arranged on the transmission seat 1, and the two limiting plates 802 are threadedly arranged at the two ends of the bidirectional screw rod 803. Preferably, the number of sliding rods 801 is two. By twisting the bidirectional screw rod 803, the two limiting plates 802 can be adjusted to slide synchronously and reversely under the action of the bidirectional screw thread and the sliding limiting of the sliding rod 801, so as to adjust the distance between the two limiting plates 802 according to the size of the cigarette box. When the cigarette box is transmitted, it passes between the two limiting plates 802, and the two limiting plates 802 limit and guide the transmission of the cigarette box, thereby improving the practicability.
[0032] As shown in the drawings, Figure 5 In some embodiments, recesses 9 are formed on the opposite sides of the two limiting plates 802, and a plurality of rollers 10 are arranged in the recesses 9. The cigarette box is made of paperboard, and the cutting part of the edge has a large friction. By forming the recesses 9 on the limiting plates 802 and arranging the rollers 10 in the recesses 9, the edge of the cigarette box rolls in contact with the rollers 10 during transmission, and the surface contact is changed to point rolling contact, thereby reducing the contact friction to ensure the smoothness of the transmission of the cigarette box.
[0033] As shown in the drawings, Figure 4 In some embodiments, the two ends of the transmission seat 1 are provided with baffles 11, and the two baffles 11 correspond to the two material passing grooves respectively. Preferably, the baffles 11 are located between the upper and lower transmission surfaces of the transmission belt 3. When hot air is continuously supplied into the drying cover 5, the air flow will be discharged from the two sides of the material passing groove under the action of air pressure. By arranging the two baffles 11, the area of the air outlet is reduced, the leakage of hot air is reduced, and the drying efficiency of the cigarette box is further improved.
[0034] As shown in the drawings, Figure 1As shown in the drawings, in some embodiments, the air inlet of the heating fan 605 is communicated with the top of the drying cover 5 through the second conveying pipe 12. Under the action of the continuous conveying of hot air, the air pressure in the drying cover 5 will increase. Under the action of the air pressure, the hot air in the drying cover 5 will still escape from the material passing groove. By communicating the second conveying pipe 12 between the air inlet of the heating fan 605 and the top of the drying cover 5, the heating fan 605 directly extracts the air flow from the inside of the drying cover 5. After the hot air blows on the cigarette box, there will still be residual heat. Extracting the air flow from the inside can recycle the residual heat of the air flow in the drying cover 5, forming a hot air circulation. At the same time, when the air flow is extracted from the top, it can effectively prevent the air flow from escaping from the material passing groove, causing heat waste, thereby improving the practicability.
[0035] As shown in the drawings, Figure 3 and Figure 6 As shown in the drawings, in some embodiments, the second conveying pipe 12 is communicated with the purification box 13. The purification box 13 is provided with an activated carbon adsorption plate 14. When the ink on the cigarette box is dried, toxic impurities contained in the ink will escape in the air flow during the drying process. By communicating the purification box 13 on the second conveying pipe 12 and setting the activated carbon adsorption plate 14 in the purification box 13, the air flow can be purified when the air flow is circulated, so that the gas in the drying cover 5 after shutdown will not pollute the external gas. The activated carbon adsorption plate 14 can be replaced regularly, thereby improving the environmental protection.
[0036] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
