Description

Technical Field

[0001] This utility model relates to the field of folding cardboard technology, specifically to a continuous folding cardboard creasing machine. Background Technology

[0002] The core solution of folding cardboard is to fold a flat, continuous sheet of cardboard into a neat, vertical stack. This makes cardboard, which was previously difficult to transport and store, much easier to transport and store, allowing customers to use it as needed. Folding cardboard is increasingly widely used in the packaging industry, primarily to meet customized needs such as furniture and complete kitchens. With the continuous increase in customization and personalization demands, the equipment for producing continuous cardboard also needs to be upgraded accordingly.

[0003] The creases in folding cardboard are the key structure for the initial folding and stacking. Therefore, creasing machines are the key equipment for producing folding cardboard. Existing creasing machines can only process creases of a single depth and shape, which limits their application range. It is also difficult to change to different creasing mechanisms, making it difficult to expand the range of folding cardboard production. Utility Model Content

[0004] To address the shortcomings of existing technologies, a continuous folding cardboard creasing machine is proposed. This solves the problems of existing creasing machines being limited to processing creasing of a single depth and shape, having a narrow range of applications, being difficult to change to different creasing mechanisms, and being unable to expand the range of folding cardboard production types.

[0005] To achieve the above objectives, the present invention proposes the following technologies:

[0006] A continuous folding cardboard creasing machine includes a creasing knife located on a creasing roller. Two sets of creasing knives are arranged and distributed circumferentially along the creasing roller. The distance between the creasing knife and the folding cardboard is adjustable to achieve creasing of the cardboard by a single creasing knife.

[0007] Furthermore, the indentation roller includes an upper indentation roller and a lower indentation roller with adjustable spacing. The upper indentation roller is driven by an adjustment component, which drives the upper indentation roller to rise and fall to adjust the spacing.

[0008] Furthermore, the adjustment assembly includes an adjustment sleeve, which is rotatably connected to a support frame for supporting the indentation roller. Rotating the adjustment sleeve causes the upper indentation roller to move closer to or further away from the lower indentation roller.

[0009] Furthermore, the adjusting sleeve is fitted around the outer periphery of the rotating shaft, the rotating shaft is coaxially arranged and fixedly connected to the upper indentation roller, and the end of the rotating shaft is rotatably connected to the mounting hole opened on the adjusting sleeve.

[0010] Furthermore, the first axis of the rotating shaft is parallel to and spaced apart from the second axis of the adjusting sleeve. When the adjusting sleeve rotates around the second axis, the rotating shaft revolves around the second axis.

[0011] Furthermore, a driven gear is fixed to the periphery of the adjusting sleeve, the driven gear meshes with the driving gear, and the driving gear is rotatably connected to the support frame.

[0012] Furthermore, two adjusting sleeves are provided, each sleeved on both ends of the rotating shaft, and two corresponding drive gears are provided and fixedly connected to both ends of the drive shaft.

[0013] Furthermore, the upper and lower indentation rollers are respectively provided with thread-contacting knives, which are inclined along the roller surface on the upper and lower indentation rollers respectively.

[0014] Compared with the prior art, the comprehensive effects brought about by this utility model include:

[0015] This application combines multiple sets of creasing knives with adjustable spacing. By adjusting the spacing of the creasing rollers, the distance between the upper and lower creasing knives is matched with the thickness of the folded cardboard, thus achieving creasing. This allows different creasing knives to perform creasing processing on the folded cardboard, meeting the different creasing processing requirements of different cardboard specifications. This broadens the applicable scenarios and scope of the machine and improves the working efficiency of the creasing machine. Attached Figure Description

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Terms such as "upper," "lower," "left," "right," and "top" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are used only for the convenience of describing the present invention and for 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, and therefore should not be construed as a limitation of the present invention.

[0021] like Figures 1 to 2 As shown, a continuous folding cardboard creasing machine includes a creasing knife 1 located on a creasing roller. Two sets of creasing knives 1 are provided, and the two sets of creasing knives 1 are distributed along the circumference of the creasing roller. The distance between the creasing knife 1 and the folding cardboard can be adjusted to achieve creasing of the cardboard by a single creasing knife 1.

[0022] With the above settings, the combination of multiple sets of creasing knives 1 and adjustable spacing allows for creasing by adjusting the spacing of the creasing rollers, thus matching the distance between the upper and lower creasing knives 1 with the thickness of the folded cardboard. This enables different creasing knives 1 to perform creasing processing on the folded cardboard, meeting the different creasing processing requirements of different cardboard specifications. This broadens the applicable scenarios and scope of the machine and improves the working efficiency of the creasing machine.

[0023] In the continuous folding cardboard creasing machine of this embodiment, the creasing rollers include an upper creasing roller 2 and a lower creasing roller 3 with adjustable spacing. The upper creasing roller 2 is driven by an adjustment component, which drives the upper creasing roller 2 to rise and fall to adjust the spacing.

[0024] Specifically, the upper creasing roller 2 and the lower creasing roller 3 are arranged opposite each other. The upper creasing roller 2 and the lower creasing roller 3 are driven to rotate by a motor so that the crease cutter 1 on their surfaces can be pressed against each other to crease the folded cardboard. The position of the lower creasing roller 3 is relatively fixed. The distance between the two creasing rollers can be adjusted by adjusting the upper creasing roller 2 to adapt to different shapes of crease cutters 1 or folded cardboard of different thicknesses.

[0025] In the continuous folding cardboard creasing machine of this embodiment, the adjustment component includes an adjustment sleeve 4, which is rotatably connected to a support frame 5 for supporting the creasing roller. Rotating the adjustment sleeve 4 causes the upper creasing roller 2 to move closer to or further away from the lower creasing roller 3.

[0026] The support frame 5 is set on both sides of the indentation roller to provide support. The upper indentation roller 2 is rotatably connected to the adjusting sleeve 4. Rotating the adjusting sleeve 4 drives the upper indentation roller 2 to rotate along the axis of the adjusting sleeve 4, thereby realizing the vertical lifting and lowering to adjust the distance between the two indentation rollers.

[0027] In the continuous folding cardboard creasing machine of this embodiment, the adjusting sleeve 4 is sleeved around the rotating shaft 6. The rotating shaft 6 is coaxially arranged and fixedly connected with the upper creasing roller 2. The end of the rotating shaft 6 is rotatably connected to the mounting hole opened on the adjusting sleeve 4.

[0028] Specifically, the first axis of the rotating shaft 6 is parallel to and spaced apart from the second axis of the adjusting sleeve 4. When the adjusting sleeve 4 rotates around the second axis, the rotating shaft 6 revolves around the second axis.

[0029] With the above configuration, the rotating shaft 6 and the adjusting sleeve 4 form an eccentric wheel mechanism, which enables the rotating adjusting sleeve 4 to drive the rotating shaft 6 to rise and fall. The rotating shaft 6 is connected to the output end of the motor, and the motor drives the rotating shaft 6 and the upper indentation roller 2 to rotate. At the same time, the motor and the rotating shaft 6 move up and down synchronously with the adjusting sleeve 4.

[0030] Preferably, in this embodiment, two sets of thread-contacting knives 1 are respectively provided on the upper and lower creasing rollers, which are used when the distance between the two creasing rollers is at its maximum and minimum. At this time, the rotating shaft 6 and the upper creasing roller 2 are aligned with the lower creasing roller 3, so as to avoid the two creasing rollers from being misaligned and affecting the normal creasing.

[0031] Specifically, the two sets of wire-contacting knives 1 are staggered to ensure that only one set of wire-contacting knives 1 performs wire-contacting processing when the upper and lower indentation rollers rotate.

[0032] Preferably, the upper and lower indentation rollers are driven by motors independently. After the distance between the upper and lower indentation rollers is adjusted, the position of the thread-fitting knife 1 to be used is detected by the detection mechanism. Based on the detected structure, the upper and lower motors are controlled to drive the indentation rollers to rotate so that the thread-fitting knife 1 is aligned and calibrated.

[0033] In the continuous folding cardboard creasing machine of this embodiment, a driven gear 7 is fixed on the periphery of the adjusting sleeve 4. The driven gear 7 is meshed with the driving gear 8, and the driving gear 8 is rotatably connected to the support frame 5.

[0034] By setting a gear transmission structure to drive the adjusting sleeve 4 to rotate on the support frame 5, the height of the rotating shaft 6 and the upper indentation roller 2 can be adjusted.

[0035] In the continuous folding cardboard creasing machine of this embodiment, there are two adjusting sleeves 4, which are respectively fitted onto the two ends of the rotating shaft 6. Correspondingly, there are two drive gears 8, which are respectively fixedly connected to the two ends of the drive shaft 9.

[0036] Specifically, one end of the drive shaft 9 is connected to the drive motor, which drives the drive shaft 9 to rotate, thereby causing the drive gears 8 on both sides to rotate, which in turn drives the driven gear 7 and the adjusting sleeve 4 to rotate.

[0037] In the continuous folding cardboard creasing machine of this embodiment, the upper creasing roller 2 and the lower creasing roller 3 are respectively provided with a creasing knife 1, and the creasing knife 1 is inclined along the roller surface on the upper creasing roller 2 and the lower creasing roller 3 respectively.

[0038] By implementing the above settings, the stress when the upper and lower wire contact knives 1 come into contact is reduced, thus preventing damage caused by the overall contact of the wire contact knives 1 and affecting normal use.

[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "rotation", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] Although embodiments of the present invention have been shown and described in detail, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
