[0002] In the papermaking industry, pulp is usually formed by grinding wood after wood is crushed, and needs to be soaked in water. Therefore, the initial pulp contains a lot of water. Therefore, after the packaging carton is made and formed, it will also contain some moisture inside. In order to improve its compressive strength, the carton is generally dried by drying equipment before leaving the factory. However, during the drying process, the bottom of the carton is always in contact with the conveying device, so the heat level is not high, and some moisture may remain at the bottom of the carton, thereby reducing the overall drying effect of the carton. In view of this, we propose a drying device for packaging carton paperboard. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] Reference Figure 1-Figure 6 , a drying device for packaging box cardboard, comprising a support frame 1, and a sealing frame 2 fixedly installed on the support frame 1, a plurality of conveying rollers 6 are rotatably installed inside the support frame 1, and a conveying belt 4 is provided on the outer transmission sleeve of the conveying roller 6, and a conveying motor 5 whose output shaft is coaxially fixed with the conveying roller 6 is fixedly installed on one side of the support frame 1, a drying component 3 for drying cardboard is provided in the sealing frame 2, and a ventilation component 7 for accelerating the drying of cardboard is provided inside the support frame 1. When the device is used, the packaging box cardboard is first placed on the conveyor belt 4, and then the conveying motor 5 is started to drive the conveying roller 6 to rotate. When the conveying roller 6 rotates, it will synchronously drive the conveyor belt 4 to operate, so as to achieve the effect of conveying the packaging box cardboard to the inside of the sealing frame 2, and then the drying component 3 arranged in the sealing frame 2 is started to dry the packaging box cardboard, and at the same time, the ventilation component 7 is used to make the hot air generated by the drying component 3 evenly contact with the packaging box cardboard, thereby improving the drying effect of the packaging box cardboard.

[0025] The ventilation assembly 7 includes a plurality of placement blocks 71 fixedly mounted on the outside of the conveyor belt 4, an arc-shaped groove is provided on the upper part of the placement block 71, and a ventilation hole 72 is provided on one side of the arc-shaped groove, and a flip assembly 73 for flipping the cardboard is provided in the middle part of the inner side of the support frame 1. Since a plurality of placement blocks 71 are provided on the conveyor belt 4, the packaging box cardboard will not directly contact the conveyor belt 4 when it is placed on the conveyor belt 4, and a certain gap is left at its bottom to facilitate the flow of hot air. Compared with the traditional drying method, the problem that the bottom of the packaging box cardboard is not easily exposed to hot air is solved. In addition, the place where the placement block 71 contacts the packaging box cardboard is provided with a ventilation hole 72 and an arc-shaped groove, which further improves the drying effect of the packaging box cardboard. In addition, when the packaging box cardboard moves to the middle of the sealing frame 2, the flip assembly 73 can be used to reverse the upper and lower sides of the packaging box cardboard, thereby enhancing the ventilation effect of the packaging box cardboard.

[0026] The flip assembly 73 includes a flip frame 731 rotatably mounted on the inner side of the support frame 1, a flip gear 1 734 is coaxially fixed to the rotating end of the flip assembly 73, and an incomplete gear 735 is meshed at the bottom of the flip gear 1 734, a flip sprocket set 736 is provided on one side of the incomplete gear 735, and a flip gear 2 737 is connected to the incomplete gear 735 through the flip sprocket set 736, and a flip gear 3 738 coaxially fixed to the conveying roller 6 is meshed at the bottom of the flip gear 2 737. The length of the flip frame 731 is less than the length of the packaging box cardboard. The lower part of the rotating gear 2 737 is meshed with a flipping gear 3 738 which is coaxially fixed with the conveying roller 6. Therefore, when the conveying roller 6 rotates, the flipping gear 2 737 can be driven to rotate through mechanical transmission. When the flipping gear 2 737 rotates, the flipping sprocket set 736 cooperates with the incomplete gear 735 to drive the flipping gear 1 734 to rotate intermittently. When the flipping gear 1 734 rotates, it will drive the packaging box cardboard to flip to another conveyor belt 4 through the flipping frame 731, thereby realizing the flipping operation of the packaging box cardboard, which is convenient for hot air to blow the packaging box cardboard.

[0027] A limiting ratchet 732 is coaxially fixed on one side of the flip gear 734, and a limiting pawl 733 elastically hinged to the support frame 1 is engaged at the lower part of the limiting ratchet 732. A driving sprocket set 739 is installed between the two conveyor belts 4. The setting of the limiting ratchet 732 and the limiting pawl 733 can prevent the flip frame 731 from deflecting when it is not rotating, thereby ensuring the stability of the flipping of the packaging box cardboard.

[0028] The support frame 1 is provided with a blocking assembly 74 for limiting the movement of cardboard. The blocking assembly 74 includes a blocking rack 741 slidably mounted inside the support frame 1. One side of the blocking rack 741 is meshed with a blocking gear 745 coaxially fixed to the flip frame 731, and the other side is fixedly mounted with a blocking link 742. One end of the blocking link 742 is fixedly mounted with a blocking plate 744 for blocking cardboard, and a blocking spring 743 with one end fixed to the support frame 1 is fixedly mounted on the upper portion of the blocking link 742. Under normal conditions, the blocking plate 744 is flush with the conveyor belt 4 and will not affect the transportation of the packaging box cardboard. When the flip frame 731 rotates, it will drive the blocking gear 745 coaxially fixed thereto to rotate synchronously. Under the transmission of tooth meshing, the blocking rack 741 will drive the blocking plate 744 to rise through the blocking link 742, thereby blocking the movement of the next packaging box cardboard, thereby ensuring the normal progress of the packaging box cardboard. Figure 6 As shown, one side of the blocking gear 745 lacks a certain number of teeth, so that it does not mesh with the blocking rack 741. After the blocking gear 745 rotates one circle, that is, after the flip frame 731 is reset, the blocking gear 745 does not mesh with the blocking rack 741. Therefore, under the action of the blocking spring 743, the blocking link 742 will drive the blocking plate 744 to fall, release the limit of the packaging box cardboard, and facilitate the normal drying of the packaging box cardboard.

[0029] Embodiment 2

[0030] Reference Figure 1-Figure 6 This embodiment is basically the same as the first embodiment, and is more optimized in that the drying component 3 includes a drying duct 31 opened inside the sealing frame 2, a filter screen 33 is provided at the connection between the drying duct 31 and the outside, a drying fan 32 is installed in the middle of the drying duct 31, and a heating resistor 34 is installed inside the sealing frame 2 and at the lower part of the drying duct 31. During drying, the drying fan 32 in the drying duct 31 can be started to convert the outside air into airflow and introduce it into the support frame 1, and the airflow can be heated by setting the heating resistor 34 in the sealing frame 2 to enhance the drying effect of the drying airflow on the packaging box cardboard.

[0031] Two flattening rollers 9 are rotatably installed at the left end of the support frame 1. One side of the flattening roller 9 is transmission-connected with a gear set 10 that meshes with each other. The rotating end of one flattening roller 9 is transmission-connected with a transmission sprocket set 8. The flattening roller 9 is transmission-connected with the conveying roller 6 through the transmission sprocket set 8. During the production process of packaging box cardboard, due to the arrangement and distribution of fibers and the influence of production technology, unevenness often occurs, which not only affects the aesthetics of the carton, but also may affect its load-bearing capacity and compressive strength. Therefore, in this solution, a flattening roller 9 is provided at the end of the support frame 1 to flatten the packaging box cardboard, so that the cardboard fibers are tightly combined, and the air and moisture therein are eliminated to make it more compact and uniform. This not only improves the flatness and thickness uniformity of the cardboard, but also enhances the quality and performance of the carton.
