DETAILED DESCRIPTION

[0020] 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.

[0021] Embodiment 1

[0022] Reference Figure 1-Figure 5 A bonding device for carton processing includes a support frame 1 and a storage box 2 fixedly installed at the left end of the support frame 1. A conveying component 3 for conveying carton paperboard is provided on the inner side of the support frame 1, and a bonding component 5 for bonding the carton is provided above the support frame 1. When the device is used, the flat carton paperboard is first placed in the storage box 2 in sequence, and then transported by the conveying component 3. During the transportation process, the carton paperboard can be formed by the bonding component 5.

[0023] The bonding component 5 includes a connecting tube 51 arranged above the support frame 1, one end of the connecting tube 51 is connected to a glue filling tube 52, and the other end is rotatably installed with a driving roller 56 in contact with the carton paperboard. A conical cavity 54 is provided inside the connecting tube 51, and the inner diameter of the conical cavity 54 decreases in sequence from left to right. A glue outlet grid 53 connected to the inner cavity is provided outside the connecting tube 51 and on the left side of the conical cavity 54. A blocking scraper 55 is slidably installed in the connecting tube 51, and a transmission component 57 for transmission connection is provided between the blocking scraper 55 and the driving roller 56. Under normal conditions, the driving roller 56 is in contact with the carton paperboard. When the carton paperboard is in the conveying component 3 When the driving roller 56 is separated from the carton board, the transmission assembly 57 drives the blocking scraper 55 to move in the direction of the conical cavity 54. During the movement, the glue at the glue outlet grid 53 is pushed into the conical cavity 54, and the conical cavity 54 is blocked, thereby preventing the residual glue in the connecting tube 51 from flowing out, thereby saving resources and reducing the difficulty of cleaning the equipment.

[0024] The transmission assembly 57 includes a transmission sleeve 571 rotatably installed inside the connecting cylinder 51 and coaxially fixed to the driving roller 56. The inner side of the transmission sleeve 571 is provided with transmission teeth, and a transmission gear 572 rotatably connected to the connecting cylinder 51 is installed through the transmission teeth. An incomplete gear 573 is meshed with the lower part of the transmission gear 572. A winding roller is coaxially fixed on one side of the incomplete gear 573, and a traction rope 574 with one end fixed to the blocking scraper 55 is wound around the winding roller. A reset sleeve 575 is fixedly installed in the connecting cylinder 51, and a reset rod 576 is slidably installed in the reset sleeve 575. One end of the reset rod 576 is fixed to the blocking scraper 55, and the other end is provided with a reset spring 577 fixed to the reset sleeve 575. Since the driving roller 56 is coaxial with the transmission sleeve 571, it will synchronously belt when rotating. The movable transmission sleeve 571 rotates. When the transmission sleeve 571 rotates, the transmission gear 572 is driven to rotate through the meshing of teeth. The transmission gear 572 meshes with the incomplete gear 573 to drive the winding roller to wind the traction rope 574, thereby pulling the blocking scraper 55 to one end of the connecting tube 51. When the incomplete gear 573 is not meshed with the transmission gear 572, the blocking scraper 55 will move to the right side of the connecting tube 51 under the action of the return spring 577, but then the transmission gear 572 will pull the blocking scraper 55 back by meshing with the incomplete gear 573, and so on, thereby achieving the effect of limiting the position of the blocking scraper 55. After the driving roller 56 is no longer in contact with the carton board, the blocking scraper 55 will move to one end of the conical cavity 54 under the action of the return spring 577, thereby sealing the glue to the conical cavity 54.

[0025] The driving roller 56 is provided with a plurality of anti-skid grooves on its exterior. The anti-skid grooves are mainly provided to increase the friction between the driving roller 56 and the paperboard surface to prevent the driving roller 56 from slipping or deviating from the direction during the sliding process. The design of the anti-skid grooves can effectively improve the grip and stability of the driving roller 56, and ensure the normal progress of the bonding work.

When the device is used, the conveying roller 33 is driven to rotate by the conveying motor 31, and then the conveyor belt 32 is driven to run synchronously. The friction between the conveyor belt 32 and the carton paperboard is used to bring the paperboard out of the storage box 2 in sequence. At the same time, the pressing plate 37 arranged on one side of the storage box 2 will press the central part of the carton paperboard. With the movement of the carton paperboard, its two sides will gradually stand upright under the action of the guide plate 1 34. When the two sides of the paperboard contact the guide plate 2 35, they will move closer to the middle and be coated with glue by the bonding component 5. When the two sides of the paperboard contact the guide plate 3 36, the two sides of the paperboard are stacked, thereby realizing the carton forming step.
