Description

Technical Field

[0001] The utility model relates to the technical field of paper tube production, in particular to a drying device for paper tube production. Background Art

[0002] Paper tubes are tubular objects made of paper. Most paper tubes are spiral paper tubes and seamless paper tubes. Since paper tubes are made of multiple layers of kraft paper, they need to be sent to a drying device for drying to solidify the glue after they are formed.

[0003] After searching, the patent with announcement number CN218627685U discloses a drying device for paper tube production. By setting a hanging plate and an arc card, the two ends of the paper tube to be dried are placed on the arc card at both ends respectively. This arrangement can facilitate the taking of the paper tube, and only requires lifting the paper tube upwards out of the arc card.

[0004] However, in actual use, the above scheme will reduce the drying efficiency of the paper tube because the disc with fixed arc clip will block the openings at both ends of the paper tube, affecting the circulation of hot air through the paper tube. In addition, the device needs to take and place the paper tubes one by one in the drying room. During this process, the drying room cannot operate, which will take up a lot of drying time.

[0005] After searching, the patent with announcement number CN219607533U discloses a drying device for paper tube production, which places the paper tube between the first fixed tube and the second fixed tube by arranging a first fixed tube, a second fixed tube, a through hole, a heating component, a fan blade, an air inlet hole, a connecting hole, a cavity and an air outlet hole, controls the motor and the heating component to work, and the rotating fan blade blows the hot air heated by the heating component when working into the interior of multiple first fixed tubes and second fixed tubes, and then blows it out from several through holes and then blows it on the inner wall and outer surface of the paper tube. At the same time, the hot air in the device can be blown back from the bottom of the first fixed tube and the second fixed tube through the air inlet hole, the connecting hole, the cavity and the air outlet hole. At this time, the hot air inside the device can circulate and flow, and the hot air in the device is blown on various parts on the support plate, so that the temperature of various parts inside the device is consistent, so that multiple paper tubes placed inside the device can be evenly dried.

[0006] Although the above scheme can use hot air to heat and dry the inner and outer walls of the paper tube simultaneously, the device also has the problem of needing to take and place the paper tubes one by one in the drying equipment, which will take up drying time and affect production efficiency.

[0007] To this end, we propose a drying device for paper tube production. Utility Model Content
