Description

Technical Field

[0001] The utility model relates to the technical field of box gluing machines, in particular to a carton gluing machine. Background Art

[0002] Carton gluer is a mechanical equipment used in carton factories to glue folding cartons. It is divided into two types: top-folding and bottom-folding. Carton gluer is generally composed of a paper feeding section, a gluing section, a folding section, and a counting and discharging section. In the general sense, carton gluer refers to equipment that completes the entire corrugated cardboard box-making process mechanically, and does not include simple gluing devices that require human participation in folding and correction.

[0003] After searching, the Chinese patent with the publication number CN218257061U discloses a corrugated paper box gluing machine. The gluing machine includes: a frame; two rotatable conveyor belts parallel to the side plates of the frame are arranged inside the frame; a plurality of blocks are fixedly arranged on the upper surface of the conveyor belt; a transverse plate and a gluing head that can move vertically along the side plates of the frame are arranged above the conveyor belt; a plurality of spring sheets are fixedly arranged near the bottom end of the side of the transverse plate; the bottom end of the spring sheet is in the same horizontal plane as the bottom surface of the block; a rotatable guide plate is symmetrically arranged on the side plate at one end of the frame; the lower surface of the guide plate is in the same horizontal plane as the bottom surface of the block. The corrugated paper box that needs to be injected with glue is corrected by the guide plate, so as to avoid the influence of the skew of the corrugated paper box caused by external reasons on the injection quality of the corrugated paper box.

[0004] However, in the above technical solution, rotatable guide plates are provided on both sides of the frame to limit the position of the warped corrugated paperboard, and then the spring sheet is used to allow the warped corrugated paperboard to pass through the baffle for gluing. However, the corrugated paperboard itself is still warped. After the corrugated paperboard is separated from the spring sheet, the warped part loses the restriction of the spring sheet and returns to its original shape. The warped corrugated paperboard contacts and collides with the gluing head, which easily causes the corrugated paperboard to tilt and cause the gluing position to deviate. Utility Model Content

After the corrugated paperboard is transported to the guide assembly by a belt conveyor, it contacts the guide inclined plate and the guide plate. When the two contact the corrugated paperboard, the crooked corrugated paperboard is gradually corrected to be parallel to the guide plate. When the corrugated paperboard enters the support frame, the steam generated by the steam generator is sprayed from the diversion box to soften the hardness of the paperboard and moisten it.

After the corrugated paperboard is transported to the guide assembly by the belt conveyor 2, it contacts the guide inclined plate 13 and the guide plate 12. When the two contact the corrugated paperboard, the crooked corrugated paperboard is gradually corrected to be parallel to the guide plate 12. When the corrugated paperboard enters the support frame 6, the steam generated by the steam generator 4 is sprayed from the diversion box 9 to soften the hardness of the paperboard and moisten it. The moistened paperboard is leveled by the rolling of the leveling wheel 7 so that when gluing it, the corners will not be bent and the gluing will not be affected.

[0026] Embodiment 2

[0027] like Figure 1 , Figure 2 , Figure 5 As shown, a carton gluing machine proposed by the utility model, compared with the first embodiment, in this embodiment, the flattening assembly includes a steam generator 4, a heating pipe 5, a support frame 6, a flattening wheel 7 and a fixed shaft 8, the steam generator 4 is arranged on one side of the gluing machine body 1, the air outlet end of the steam generator 4 is connected to the heating pipe 5, one end of the heating pipe 5 passes through the through hole on the gluing machine body 1 and is connected to the U-shaped support frame 6, and symmetrical fixed shafts 8 are provided at the upper and lower ends of one side of the support frame 6, and the fixed shaft 8 is rotatably connected to the flattening wheel 7.
