Description

Technical Field

[0001] This utility model belongs to the field of packaging box production technology, and in particular relates to a double-toothed directional bending template. Background Technology

[0002] Flatbed die-cutting technology, with its high precision and excellent forming effect, has become a mainstream process in today's increasingly automated packaging industry. The precision of the die-cutting plate directly determines the processing quality of the final product. Especially for flexible materials such as corrugated paper, even with the support of flatbed die-cutting, it is still difficult to guarantee that the dimensions are completely consistent. Therefore, to improve the throughput of corrugated paper products on automated packaging lines, efforts must be made to improve the production of die-cutting plates.

[0003] Taking the corrugated cardboard box as an example, its simple structure, lack of need for adhesive nails, ease of transportation and storage, and good texture after packaging make it widely used in electronics, food, and pharmaceutical industries. The corrugated cardboard box is made from a single sheet of corrugated cardboard, cut and creasing using die-cutting lines, toothed lines, and crease lines, relying on creases to achieve interlocking folding. The interlocking parts employ a double-fold design to ensure a secure connection. To ensure accurate creases, a toothed point-cutting process is often used; however, the order in which the two fold lines are folded must be maintained during use. If the order is reversed, folding will not continue, causing the machine to jam and stop. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a double-toothed directional bending template, which structurally ensures that the folding action must be performed in a predetermined order, thereby completely solving the problems of jamming and stopping caused by the reversal of the order.

[0005] This utility model is implemented as follows: a double-toothed directional bending template is used for carton forming. A double fold line is provided between the flap and the side wall at the interlocking position of the carton. The double fold line includes a first fold line and a second fold line provided inside the first fold line. The template includes a base plate. The working surface of the base plate is provided with a die-cutting knife set according to the outer contour of the carton unfolding diagram. A creasing knife set is provided inside the closed shape formed by the die-cutting knife set. The creasing knife set is used to press the folds of the corrugated cardboard. A first toothed cutter is provided at the substrate position for processing the first crease, and an indentation blade and a second toothed cutter are provided at the substrate position for processing the second crease.

[0006] Furthermore, the second toothed cutter and the indentation insert are installed in the same groove, with the cutting edge of the second toothed cutter positioned above the cutting edge of the indentation insert, and the height difference being 0.1~3 mm.

[0007] Furthermore, the distance between the first crease and the second crease is 1 to 2 times the thickness of the corrugated cardboard.

[0008] Furthermore, the height of the indentation blade is 22.9 mm, and the height of the second toothed blade is 23.1 mm.

[0009] Furthermore, sponge strips are respectively provided on the inner and outer substrates of the die-cutting blade.

[0010] Furthermore, a groove is provided on the working end face of the substrate, and the die-cutting blade, the creasing blade, the first toothed blade, and the second toothed blade are all disposed in the groove.

[0011] Furthermore, the embossing blade, the first toothed blade, and the second toothed blade in the embossing tool assembly all have blunt cutting edges.

[0012] The advantages and technical effects of this invention are as follows: By adopting the above-mentioned technical solution, the first crease and the second crease produce differentiated folding forces. A combined processing method is used at the processing position of the second crease, which simultaneously possesses the point-breaking effect of the toothed blade and the pre-pressure guidance of the crease line. This significantly enhances the foldability of the second crease, making it far more flexible than the first crease processed solely with the toothed blade. This ensures that the folding action is guided by the second crease, structurally guaranteeing that the folding action must be performed in a predetermined sequence. This completely solves the problem of jamming and machine stoppage caused by reversed sequence, greatly improving the throughput of cartons on automated equipment. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0016] It should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] like Figure 1 and Figure 2 As shown, this application provides a double-toothed directional bending template for carton forming. A double fold line is provided between the flap and sidewall at the interlocking position of the carton. The double fold line includes a first fold 8 and a second fold 9 located inside the first fold 8. The template includes a base plate 1. A die-cutting blade assembly 2 is provided on the working surface of the base plate 1 according to the outer contour of the carton's unfolded shape. A creasing blade assembly 3 is provided inside the closed shape formed by the die-cutting blades. The creasing blade assembly 3 is used to press creases on the corrugated cardboard. Specifically, the die-cutting blade assembly 2 includes multiple die-cutting blades. According to the outer contour of the carton's unfolded shape, the die-cutting blades include horizontal die-cutting blades, vertical die-cutting blades, and bending die-cutting blades. The multiple die-cutting blades are combined to form a closed shape corresponding to the outer contour of the carton's unfolded shape. The creasing blade assembly 3 includes multiple creasing blades 5. The installation position of the creasing blades on the base plate 1 is set according to the crease position of the carton's unfolded shape. The creasing blades 5 include horizontal creasing blades 5 and vertical creasing blades 5.

[0018] A first toothed blade 4 is provided at the position of the substrate 1 used to process the first crease 8, and an indentation blade 5 and a second toothed blade 6 are provided at the position of the substrate 1 used to process the second crease 9.

[0019] Preferably, the second toothed blade 6 and the creasing blade 5 are installed in the same groove, with the cutting edge of the second toothed blade 6 positioned above the cutting edge of the creasing blade 5, and the height difference being 0.1~3 mm. Specifically, the height of the creasing blade 5 is 22.9 mm, and the height of the second toothed blade 6 is 23.1 mm. The second toothed blade 6 first contacts and cuts the corrugated cardboard, and then the creasing blade 5 presses out a clear crease line. This composite processing line of cutting before creasing provides a more defined crease guide compared to the first crease 8 processed solely by the toothed blade. Integrating the second toothed blade 6 and the creasing blade 5 into the same groove fundamentally ensures the parallelism and spacing accuracy of the two cutting edges on the substrate 1, and enables simultaneous cutting and creasing, significantly improving the production efficiency of a single die-cutting operation.

[0020] Preferably, the distance between the first crease 8 and the second crease 9 is 1 to 2 times the thickness of the corrugated cardboard.

[0021] Preferably, sponge strips 7 are respectively provided on the inner and outer substrates 1 of the die-cutting blade. The elasticity of the sponge strips 7 effectively solves the problem of blade sticking during the die-cutting process, ensuring smooth material ejection.

[0022] Preferably, a cutting groove is provided on the working end face of the substrate 1, and the die-cutting blade, the creasing blade, the first toothed blade 4 and the second toothed blade 6 are all disposed in the cutting groove.

[0023] Preferably, the cutting edges of the indentation blade 5, the first toothed blade 4, and the second toothed blade 6 in the indentation blade assembly 3 are all blunt cutting edges.

[0024] By employing the aforementioned technical solution, the first crease 8 and the second crease 9 exhibit differentiated folding forces. A combined processing method is used at the processing position of the second crease 9, which simultaneously possesses the point-cutting effect of the toothed blade and the pre-pressure guidance of the crease line. This significantly enhances the foldability of the second crease 9, making it far more flexible than the first crease 8, which is processed solely by the toothed blade. This ensures that the folding action of the second crease 9 is guided by a predetermined sequence, thus completely resolving the jamming and stopping problems caused by reversed sequences and greatly improving the throughput of cartons on automated equipment.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
