Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a glue coating and drying device for packaging paper boxes. Background Art

[0002] In the process of manufacturing packaging paper boxes, it is often necessary to apply glue to the surface of the paper boxes, which can firmly bond all parts of the paper boxes together to ensure the integrity and stability of the paper box structure. After the applied glue is smeared on the surface of the paper box, it is necessary to dry the glue on the surface to ensure the curing of the glue, improve the bonding strength, and guarantee the packaging quality. However, the current drying devices are often placed in a relatively fixed position, which reduces the drying effect, may cause incomplete drying of the glue on the surface of the paper box, and thus affects the packaging quality of the paper box.

[0003] In order to improve the drying efficiency and quickly dry the glue on the surface of the paper box, Chinese Patent CN221433773U, a glue coating and drying device for packaging boxes, points out that through the set drying structure, the purpose of drying the packaging paper box after glue coating is achieved. Through the set transmission structure, the paper box can be transported into the drying device and can drive the paper box to rotate in the drying device, so that the paper box can fully contact the drying source, thus achieving the purpose of uniform drying, accelerating the air circulation in the drying device cavity, improving the drying efficiency, and ensuring the drying quality. The above patent can be based on the attachment of the patent Figure 1 and the attachment Figure 2 It can be seen that placing the paper box on the placement block and then realizing the rotation of the placement block in the U-shaped working box through the cooperation of the chain and the gear. Although this method speeds up the drying efficiency, there are still certain problems. It cannot meet the placement of paper boxes of different specifications. Secondly, when it is necessary to take out the paper box, it is not convenient to take it due to the rotation of the placement block. Moreover, the placement block drives the simultaneous rotation of the paper box and the placement block, but the rotation of the paper box itself cannot be realized. In comparison, if the paper box itself can rotate, this method has a better drying effect than the drying effect of the above patent in which the placement block drives the simultaneous rotation of the paper box.

[0004] Therefore, in order to be able to drive the paper box to move and secondly to realize the rotation of the paper box itself, thereby cooperating with the hot air blowing device to accelerate the drying efficiency of the paper box, and secondly to facilitate the placement and taking out, a glue coating and drying device for packaging paper boxes is hereby proposed to solve the technical problems in the above-mentioned prior art.

Detailed implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0024] Please refer to Figures 1-8 , the present invention provides the following technical solutions: A glue coating and drying device for packaging cartons, including a device frame 1, a drying box 6 is installed on the device frame 1, a transmission structure is provided on the right side surface of the device frame 1, the transmission structure horizontally passes through the inside of the drying box 6, a hot air blowing device 5 is installed on the upper end of the drying box 6, a rotatable clamping structure is installed on the transmission structure, and an inner box plate 16 is further installed on the inner side surface of the drying box 6. The inner box plate 16 and the inner side surface of the side drying box 6 form a cavity. Openings are provided on the upper end surface and the front and rear side surfaces of the inner box plate 16. The blowing end of the hot air blowing device 5 extends into the cavity. A guiding strip 10 is installed on the inner bottom of the drying box 6. A rubber pad is provided on the rear side surface of the guiding strip 10, and the rubber pad contacts the clamping structure. The clamping structure includes a connecting rod 11, a roller 12, a rotating rod 13, an elastic sheet 14, and a connecting plate 15; the connecting rod 11 is installed on the transmission structure and moves with the movement of the transmission structure. A connecting plate 15 is installed in the middle of the connecting rod 11. A bearing is installed on the connecting plate 15. A rotating rod 13 is connected to the inner ring of the bearing. A roller 12 is installed at the lower end of the rotating rod 13. The roller 12 contacts the rear end of the guiding strip 10. An elastic sheet 14 is installed at the upper end of the rotating rod 13.

[0025] In this implementation, the specific working principle is as follows: When the device is running, the carton with glue on its surface is placed on the rotating rod 13 with the opening facing downwards. The carton is clamped by the elastic sheet 14 and then moves along with the movement of the transmission structure. During the movement, the hot air blowing device 5 sucks external air into the cavity formed by the inner box plate 16 and the drying box 6. When the transmission structure is driving, the roller 12 contacts the guiding strip 10. Since a rubber pad is installed at the rear side of the guiding strip 10, when the roller 12 contacts, due to the friction force, the rotating rod 13 rotates, thereby driving the carton to rotate, and the hot air is blown out through the openings on the surface of the inner box plate 16, achieving the effect of drying the surface of the carton. Secondly, the elastic sheet 14 can adapt to the clamping of cartons of different specifications, so it can efficiently dry cartons of various specifications and sizes. Therefore, this device solves the problems in the prior art, such as low drying efficiency for the glue coating on packaging cartons, inconvenient handling and placement, and the inability to adapt to the drying of cartons of different specifications and sizes.

[0026] According to the above, in order to prevent the problem of damage to the inner side of the carton caused by the elastic sheet 14 when the carton is placed on the rotating rod 13, please refer specifically to Figure 7 It can be seen that the end of the elastic sheet 14 is bent downwards. In order to prevent collision between the roller 12 and the guiding strip 10 when the roller 12 enters the drying box 6, please refer specifically to Figure Figure 8 It can be seen that the right end of the guiding strip 10 is bent, and 17 is installed on the right end face of the side mounting plate 2 on its side.

[0027] For the specific transmission structure mentioned above, please refer specifically to Figure 2 It can be seen that the transmission structure includes side mounting plates 2 installed on the left and right sides of the device frame 1. A servo motor 3 is installed on the front side of the side mounting plate 2. The output end of the servo motor 3 is connected to a rotating shaft 7. A gear 8 is installed on the surface of the rotating shaft 7. A tooth chain 9 is sleeved on the surface of the gear 8. A connecting rod 11 is arranged on the side of the tooth chain 9. By driving the rotating shaft 7 to rotate through the servo motor 3, the tooth chain 9 is driven to rotate through the gear 8, so as to drive the connecting plate 15 to move through the connecting rod 11.

[0028] Refer to Figure 1 and Figure Figure 5 、 Figure 6 It can be seen that the hot air blowing device 5 is installed at the upper end of the drying box 6. The hot air blowing device 5 includes a hot air blowing mounting base 501, a blower 502, and an electric heating tube 503.
