Description

Technical Field

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

[0002] Paper tubes are tubular objects made from paper. Most paper tubes come in spiral or seamless varieties. They are commonly used in industries like chemical fiber, film, printing, and papermaking. During production and processing, they require drying to maintain their rigidity and prevent deformation. A large amount of liquid colloid is used during the rolling process, making drying essential for the finished product.

[0003] Currently, paper tube drying devices usually directly place the formed paper tubes in a drying oven to heat and dry them. However, the glue on the newly formed paper tubes has not yet been initially solidified. At this time, if the paper tubes are directly transferred to the drying oven for drying, they need to contact the paper tubes during the transfer process. During the contact, the glue is pressurized and moves around, resulting in uneven glue distribution, which in turn affects the flatness of the paper tube surface. At the same time, during the paper tube transportation process, due to the different paper tube spacing in different directions and the different directions of natural wind, the degree of glue solidification on each surface will be uneven. The glue may not solidify in some directions of the paper tube. When the operator directly removes the paper tube, the glue may move around, resulting in uneven glue distribution. Utility Model Content

[0004] In order to solve the above problems, the purpose of the present invention is to provide a chain-type paper tube natural drying device, which allows the paper tube itself to be dried during the paper tube transmission process, thereby avoiding as much as possible the different degrees of glue solidification on the outside of the paper tube, which causes the glue to move around when taking it and the occurrence of uneven glue distribution.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A chain-type paper tube natural drying device comprises a workbench, a pair of conveying mechanisms symmetrically fixed on the front and rear sides of the workbench, a motor fixed on the outside of any one of the conveying mechanisms and used to drive the conveying mechanism, and a plurality of paper tubes arranged in parallel and spaced apart between the two conveying mechanisms; the conveying mechanism comprises a mounting plate fixed on the upper surface of the workbench along the length direction of the workbench, a plurality of transmission belts serpentinely distributed and installed on the inner side surface of the mounting plate, a slide rail embedded on the inner side surface of the mounting plate along the transmission direction of the transmission belt, a plurality of fixed components slidingly arranged at intervals in the slide rail for fixing the paper tubes, and a plurality of guide plates evenly fixed on the outside of the transmission belt and used to drive the fixed components to move; each of the fixed components is located inside the mounting plate and is fixed with a gear at one end, a serpentine cavity connected to the slide rail is opened inside the mounting plate, and a plurality of racks meshing with the gear are fixed on the side wall of the serpentine cavity.

[0007] More preferably, each group of the fixing components includes a guide sleeve with one end fixed to the gear and the other end passing through the slide rail and the transmission component in sequence and extending to the outer surface of the transmission component, a limit rod movably sleeved inside the guide sleeve, and a return spring arranged between the guide sleeve and the limit rod; the limit rods in the two relatively arranged groups of fixing components clamp the paper tube from both ends of the paper tube.

[0008] More preferably, each guide plate is L-shaped, and the inner side surface of the guide plate fits with the outer side wall of the guide sleeve.

[0009] The utility model has the following beneficial effects:

[0010] 1. The utility model limits the paper tube by extending two fixed drills from both ends of the paper tube into the hollow position in the middle of the paper tube, thereby driving the paper tube for transmission. During the transmission process, it can avoid contact with the glue on the outside of the paper tube as much as possible, thereby reducing the occurrence of uneven glue distribution;

[0011] During the transmission process of the fixed component of the present invention, the meshing action of the gear and the rack will cause the fixed component and the paper tube to rotate, so that the paper tube itself rotates while moving along the transmission direction of the transmission belt, so that the outer side of the paper tube is subjected to the same wind force in all directions, thereby avoiding as much as possible the different degrees of solidification of the paper tube in all directions, and then avoiding as much as possible the situation where the glue in some directions of the paper tube is not solidified and the glue moves around in the hand when taking the paper tube, resulting in uneven distribution of glue.

[0020] The guide plates 25 fixed to the outside of the transmission belts 22 are driven to rotate by the plurality of transmission belts 22, thereby gradually pushing the fixed assembly 24 to slide along the transmission direction of the plurality of transmission belts 22, thereby realizing the transmission of the paper tube 4; during the transmission process of the fixed assembly 24, due to the meshing action of the gear 26 and the rack 212, the fixed assembly 24 and the paper tube 4 are rotated, thereby realizing that the paper tube 4 rotates while moving along the transmission direction of the transmission belts 22, so that the outer side of the paper tube 4 is subjected to the same wind force in all directions, thereby avoiding as much as possible the different degrees of solidification of the paper tube 4 in all directions, and then avoiding as much as possible the occurrence of uneven glue distribution caused by the glue not solidifying in some directions of the paper tube 4 and the glue moving around when the paper tube 4 is picked up; the two fixed drills 24 extend from both ends of the paper tube 4 into the hollow position in the middle of the paper tube 4 to limit the paper tube 4, thereby driving the paper tube 4 to be transmitted, and avoiding as much as possible contact with the glue on the outside of the paper tube 4 during the transmission process, thereby reducing the occurrence of uneven glue distribution.
