Description

Technical Field

[0001] The utility model belongs to the technical field of carton production equipment, in particular to a device for preventing scissor difference in the stapling of corrugated carton. Background Art

[0002] Cartons are the main packaging products currently used. The basic material of cartons is corrugated cardboard, which is made into cartons through cutting, folding, gluing, stapling and other steps. With the increasing degree of mechanization in corrugated carton manufacturing, some problems that were not easy to occur in the manual era have gradually emerged. In the stapling process, some large cartons that cannot be processed automatically need to be completed using semi-automatic carton stapler equipment; the semi-automatic carton stapler equipment is equipped with two upper and lower belts or two sets of wheels, and the nail head is located in the center of the equipment. The carton that needs to be stapled is folded and fed into the belts or wheels on both sides of the equipment. The tongue of the middle joint of the carton is aligned with the bottom mold, and the nail wire is buried between the bottom mold and the nail head. After receiving the command, the upper belt or wheel is pressed down, and the first nail is nailed out after clamping the cardboard; when the nail head is lifted, the cardboard moves forward to the set nail distance value under the drive of the stepper motor, and the nail head falls and lifts again, and the carton moves forward, and it is automatically discharged after the set number of nails is completed, and the stapling of a carton is completed.

[0003] During the nailing process, every time a nail is nailed, the carton will expand and tilt outward due to the impact and compression of the nail head. Since the front of the carton has been nailed, this force will be released little by little to the tail end, causing the gap at the tail end of the carton to become larger and larger. After the carton is formed, the gaps at both ends are different, one end is large and the other end is small, thus forming a scissors gap. The more nails there are, the more serious the scissors gap is, which seriously affects the use and appearance of the carton. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model aims to propose a device for preventing scissor differences in the nailing of corrugated cardboard boxes, which solves the problem that during the carton nailing process, especially when double-leaf nails are formed, the carton will expand and tilt outward due to the impact and compression of the nail heads, resulting in a scissor difference in the front and rear gaps of the carton nailing.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] A corrugated paper box stapling anti-scissor difference device comprises a stapling machine frame, on which two sets of symmetrically arranged paper feed mechanisms are installed, each set of paper feed mechanisms comprises an upper paper feed mechanism and a lower paper feed mechanism, and both sides of the folded paper box that needs to be stapling are respectively located between the two sets of upper paper feed mechanisms and the lower paper feed mechanisms, and the two lower paper feed mechanisms are respectively installed with a linkage plate for adjusting the position of the lower paper feed mechanism;

[0007] A group of guide devices for preventing the carton from expanding outward during stapling are respectively installed on the two linkage plates, and the two groups of guide devices are respectively located on the outside of the two groups of paper feeding mechanisms; the guide device includes a fixed seat, a guide sleeve and a guide shaft bolt, and the side of the fixed seat is connected to the linkage plate; the guide sleeve is rotatably installed on the fixed seat through the guide shaft bolt, and the guide sleeves of the two groups of guide devices are respectively in contact with the two sides of the stapled carton, so that the guide sleeve rotates as the stapled carton moves forward.

[0008] Furthermore, one end of the shaft body of the guide shaft bolt is a head, and the other end is a tail. The shaft body is rotatably connected to the guide sleeve, and the tail is detachably connected to the fixing seat.
