Description

Technical Field

[0001] The utility model belongs to the technical field of carton production, and particularly relates to a secondary crimping correction mechanism and a carton gluing machine. Background Art

[0002] Cartons are the main packaging products currently used. The basic material of cartons is corrugated cardboard, which is cut and folded to form cartons. As the demand for the load-bearing and compression resistance of cartons becomes increasingly prominent, corrugated cardboard is made of multiple layers of base paper. In the folding and gluing process of the carton gluing machine, the cardboard is folded nearly 180°, and there will be bulging at the folding point. Therefore, affected by the accuracy of the carton cutting equipment and the characteristics of the cardboard itself, the congestion at the folding point of the carton often causes inconsistent joint gaps after forming during the forming process. Summary of the invention

[0003] In view of the problems existing in the prior art, the utility model provides a secondary crimping correction mechanism and a box gluer, which can correct the crimping at the folding point and effectively avoid congestion and bulging at the folding point, thereby ensuring the consistency of the forming interface and improving product quality and pass rate.

[0004] The utility model is implemented as follows: on one hand, the application provides a secondary crimping correction mechanism, including a crimping wheel and a lower crimping wheel arranged in a paper folding area of ​​a box gluer, wherein the crimping wheel is rotatably arranged on a frame on the outer surface of a carton, and a concave portion abutting against a folded portion on the outer surface of the carton is arranged on the cylindrical surface of the crimping wheel;

[0005] The line-pressing lower wheel is rotatably arranged on a frame on the inner surface of the carton, and the outer edge of the line-pressing lower wheel is provided with a protrusion matching the recessed portion, and the protrusion abuts against the folded portion of the inner surface of the carton.

[0006] Furthermore, the axis a of the crimping wheel and the axis b of the lower crimping wheel are arranged in a colinear manner, so that the crimping position can be accurately aligned to achieve a high-precision crimping operation.

[0007] Furthermore, the cross section of the recessed portion is a V-shaped cross section, and the recessed portion includes two intersecting arc surfaces, and the intersection of the two arc surfaces has a rounded transition. The arc surface and the rounded transition can prevent the creasing wheel from damaging the carton during the creasing process.

[0008] Furthermore, the cross section of the protrusion is a conical cross section, and the end of the protrusion is provided with a transition fillet. The provided conical cross section can be more compatible with the shape of the concave portion, and the folding position of the carton can be more effectively pressed, and the transition fillet can avoid damage to the folding position of the carton.

[0009] Furthermore, an upper wheel mounting hole is provided through the wire-pressing upper wheel, the axial direction of the upper wheel mounting hole is perpendicular to the axis a of the wire-pressing upper wheel, the wire-pressing upper wheel is arranged on the upper wheel mounting shaft of the frame through the upper wheel mounting hole, and an upper wheel bearing is arranged between the wire-pressing upper wheel and the upper wheel mounting shaft.

[0010] Furthermore, a lower wheel mounting hole is provided in the line pressing lower wheel, the axial direction of the lower wheel mounting hole is perpendicular to the axis b of the line pressing lower wheel, the line pressing lower wheel is arranged on the lower wheel mounting shaft of the frame through the lower wheel mounting hole, and a lower wheel bearing is arranged between the line pressing lower wheel and the lower wheel mounting shaft.

[0011] On the other hand, the present application provides a box gluer, and the above-mentioned secondary pressure line correction mechanism is arranged on the frame of the paper folding area of ​​the box gluer.

[0019] like Figures 1 to 3 As shown, the present application provides a secondary crimping correction mechanism, including a crimping wheel 1 and a lower crimping wheel 2 arranged in the folding area of ​​the box gluing machine, the crimping wheel 1 is rotatably arranged on the frame on the outer surface of the carton, specifically, the crimping wheel 1 is provided with an upper wheel mounting hole 1-3, the axial direction of the upper wheel mounting hole 1-3 is perpendicular to the axis a of the crimping wheel 1, the crimping wheel 1 is arranged on the upper wheel mounting shaft of the frame through the upper wheel mounting hole 1-3, and an upper wheel bearing is arranged between the crimping wheel 1 and the upper wheel mounting shaft. A recessed portion 1-1 is arranged on the cylindrical surface of the crimping wheel 1, which abuts against the folding part of the outer surface of the carton. Further, the cross section of the recessed portion 1-1 is a V-shaped cross section, and the recessed portion 1-1 includes two intersecting arc surfaces 1-2, and the intersection position of the two arc surfaces 1-2 is rounded. The arc surface 1-2 and the rounded transition can prevent the crimping wheel 1 from damaging the carton during the crimping process.

[0020] The lower crimping wheel 2 is rotatably arranged on the frame of the inner surface of the carton. Specifically, a lower wheel mounting hole 2-2 is provided in the crimping wheel 2, and the axial direction of the lower wheel mounting hole 2-2 is perpendicular to the axis b of the crimping wheel 2.
