Description

Technical Field

[0001] This invention relates to the field of box sheet processing technology, and in particular to a slotting device, method and box making system for rigid cardboard. Background Technology

[0002] Conventional cigarette packaging boxes are made of paper materials and printed with ink. Cigarette boxes are generally disposable and consumed in large quantities. Existing factories can achieve large-scale production through automated machinery.

[0003] In existing technologies, cigarette boxes are typically made by creasing paper to form a box sheet with certain creases, and then bending it based on these creases to form the box body. However, the creasing process can only be used to continuously crease in a single direction, which can damage parts that do not need creasing. It also results in the problem that the perpendicularity of the bent parts is not high after the creasing-formed box sheet is folded into a box body. Summary of the Invention

[0025] The grooving blade of the sixth grooving device performs a sixth grooving on the rigid cardboard in the second direction along the preset back printing line.

[0026] The preset back printing line includes two rows of 12 boxed products, with the first direction and the second direction perpendicular to each other.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] This invention provides a slotting device for rigid cardboard, which solves the technical problems of existing box sheets using the creasing process, which can only be creasing continuously in one direction, thus damaging parts that do not need creasing, and the creasing-formed box sheet not having high verticality at the bending point after being folded into a box body.

[0051] See Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a slotting device for rigid cardboard, comprising: a conveying component 1, at least one moving component 2, at least one slotting head 3, and a control component.

[0052] The conveying assembly 1 is used to convey rigid cardboard to be slotted, and the moving assembly 2 is disposed on the side of the conveying assembly 1 where the rigid cardboard to be slotted is conveyed. One slotting head 3 is connected to one moving assembly 2, and each slotting head 3 is provided with a slotting blade 31.

[0053] A control component, electrically connected to the conveying component 1 and the moving component 2, is configured to:

[0054] The control assembly 1 conveys the rigid cardstock to be slotted and drives any of the moving components 21 to move, causing the slotting blade 31 of the corresponding slotting head 3 to slot the rigid cardstock along a preset back printing line. Optionally, the control assembly is a programmable logic controller (PLC). A PLC is a digital computing and operating electronic system specifically designed for industrial applications, featuring high reliability, easy programming, flexible configuration, convenient installation, and fast operation.

[0055] The following example, using a pre-printed back line comprising two rows of 12 box-shaped products, further illustrates the operation of the slotting device for rigid cardboard of the present invention:

[0056] See Figure 2 and Figure 3 As shown, any rigid cardstock has two rows of back printing lines (dashed lines) for 12 boxed products printed on it. In the cardstock grooving device of this embodiment, eight moving components 2 are spaced apart. Each moving component 2 has a grooving head 3 with a grooving blade 31. Six cardstock grooving devices provided in this embodiment are arranged sequentially. When the first grooving device's conveying component 1 conveys the cardstock to be grooved, it drives the eight moving components 2 to move, causing the grooving blades 31 of the corresponding grooving heads 3 to groove the cardstock along the preset back printing lines (solid lines). Under the action of the moving components 2, the grooving blades 31 continuously and spaced out multiple grooves in a first direction.

[0057] See Figure 4 As shown, the grooving blade 31 of the second grooving device performs a second grooving on the rigid cardboard in the first direction along the preset back printing line.

[0058] See Figure 5 As shown, the grooving blade 31 of the third grooving device performs a third grooving on the rigid cardboard in the first direction along the preset back printing line.

[0059] See Figure 6 As shown, the grooving blade 31 of the fourth grooving device performs a fourth grooving on the rigid cardboard in the second direction along the preset back printing line.

[0060] See Figure 7 As shown, the grooving blade 31 of the fifth grooving device performs a fifth grooving on the rigid cardboard in the second direction along the preset back printing line.

[0061] See Figure 8As shown, the grooving blade 31 of the sixth grooving device performs a sixth grooving on the rigid cardboard in the second direction along the preset back printing line.

[0062] After six processes using the six slotting devices described above, slots are cut along the back printing lines of 12 box pieces on a sheet of rigid cardboard. Finally, 12 box pieces are die-cut, and then folded along the slotted lines to form the box body. It should be noted that the specific number of slotting devices used can be adjusted according to actual needs, and the number of slotting blades 31 in each slotting device can also be adjusted as needed. Figures 3-8 The order of slotting can also be adjusted according to actual needs.

[0063] The grooving device for rigid cardboard in this embodiment of the invention includes at least one moving component, at least one grooving head, and a control component. Each grooving head is connected to a corresponding moving component. Each grooving head is equipped with a grooving blade 31. The control component controls and drives any moving component to move, causing the grooving blade of the corresponding grooving head to groove the rigid cardboard along a preset back printing line. The grooved box sheet of this invention, after being folded into a box body, exhibits high verticality at the bends, resulting in a more three-dimensional box body. Furthermore, areas where grooving is not required are not grooved, ensuring the strength of the box sheet.

[0064] As an optional implementation, in one embodiment of the invention, the slotting device for rigid cardboard further includes a detection component, which is used to detect the position of a preset back printing line on the cardboard to be slotted and send the detection result to the control component. The detection component can guide the control component to drive the moving component 21 to move, so that the slotting blade 31 of the corresponding slotting head 3 can be aligned with the preset back printing line, thereby improving the slotting accuracy.

[0065] Furthermore, the detection component includes an image acquisition camera, which can acquire an image of a preset back printing line on a rigid cardstock and determine the position of the preset back printing line based on the image of the preset back printing line.

[0066] As an optional implementation, in one embodiment of the invention, the grooving blade 31 includes two blade bodies forming a V-shape. The V-shape of the grooving blade 31 facilitates material removal during grooving.

[0067] As an optional implementation, in one embodiment of the invention, the moving component includes a servo motor or a stepper motor. Using a servo motor or stepper motor provides high control precision and ease of control.

[0068] This invention provides a method for slotting rigid cardboard, using multiple of the aforementioned rigid cardboard slotting devices, including the following steps:

[0069] The conveying component 1 of a slotting device is used to convey the rigid cardboard to be slotted, and any moving component 21 of the slotting device is driven to move, so that the slotting blade 31 of the corresponding slotting head 3 slots the rigid cardboard along the preset back printing line.

[0070] Specifically, see Figures 3 to 8 As shown, the conveying assembly 1 of a slotting device sequentially conveys the rigid cardboard to be slotted, and drives any moving assembly 21 of the slotting device to move, so that the slotting blade 31 of the corresponding slotting head 3 slots the rigid cardboard along a preset back printing line, including:

[0071] The grooving blade 31 of the first grooving device performs the first grooving on the rigid cardboard in the first direction along the preset back printing line.

[0072] The grooving blade 31 of the second grooving device performs a second grooving on the rigid cardboard in the first direction along the preset back printing line.

[0073] The grooving blade 31 of the third grooving device performs a third grooving on the rigid cardboard in the first direction along the preset back printing line.

[0074] The grooving blade 31 of the fourth grooving device performs a fourth grooving on the rigid cardboard in a second direction along a preset back printing line.

[0075] The grooving blade 31 of the fifth grooving device performs a fifth grooving on the rigid cardboard in the second direction along the preset back printing line.

[0076] The grooving blade 31 of the sixth grooving device performs a sixth grooving on the rigid cardboard in a second direction along a preset back printing line.

[0077] The preset back printing line includes two rows of 12 boxed products, with the first direction and the second direction perpendicular to each other.

[0078] The grooving method for rigid cardboard in this embodiment of the invention results in a high degree of verticality at the bends after the grooved box sheet is folded into a box body, making the box body more three-dimensional. Furthermore, no grooving is required for areas where grooving is not necessary, thus ensuring the strength of the box sheet.

[0079] Additionally, see Figure 2 As shown, Figure 2 for Figure 3The diagram below shows the grooving process for the box panel in the lower left corner. The first and second processes use two grooving blades 31. The third process is omitted. The fourth process uses five grooving blades 31. The fifth process uses three grooving blades 31. The sixth process is omitted. In the first and second processes, taking the leftmost dotted line as an example, the grooving in the first and second processes has a pre-set misalignment to facilitate folding the box. This is difficult to achieve with continuous indentation in a single direction. In the fourth and fifth processes, the bottommost dotted line shows two consecutive groovings, also with a pre-set misalignment, to widen the grooving width for 180-degree bending. Similarly, the middle dotted line shows a pre-set misalignment between the grooving in the fourth and fifth processes to facilitate folding the box. Figure 7 and Figure 8 In some cases, there is also the operation of widening the groove width by making two consecutive grooves at the same dotted line.

[0080] See Figure 9 As shown, an embodiment of the present invention provides a box-making system, including: a paper feeding device, a printing device, a slotting device for a plurality of the aforementioned rigid cardboard sheets, and a die-cutting device.

[0081] The paper feeding device is used to provide rigid cardboard, the printing device is used to print a preset back printing line on the rigid cardboard in the conveying direction, the aforementioned slotting devices are used to slot the printed rigid cardboard in the conveying direction, and the die-cutting device is used to die-cut the slotted rigid cardboard in the conveying direction.

[0082] The box-making system in this embodiment of the invention does not perform grooving on parts that do not need grooving, thus ensuring the strength of the box sheet. At the same time, the box sheet formed by grooving has a high degree of verticality at the bending point after being folded into a box body, making the box body more three-dimensional.

[0083] As an optional implementation, in one embodiment of the invention, the die-cutting device is also used to apply glue lines to the slotted rigid cardboard in the conveying direction.
