Description

Technical Field

[0001] This application relates to the field of automated processing equipment for corrugated cardboard boxes, and more particularly to a slotting and crimping mechanism and a box-making machine including the same. Background Technology

[0002] The background description provided herein serves to give a general overview of the background of this application. The work to the extent described by the currently identified inventors in this background section, and aspects of this description that do not constitute prior art at the time of application, are neither expressly nor impliedly acknowledged as prior art in conflict with this application.

[0003] The slotting and creasing mechanism is an important component of cardboard box processing equipment, capable of slotting and creasing cardboard to form boxes. Existing technologies, such as the slotting and creasing mechanism disclosed in CN210881089U, mount the slotting and creasing devices on a single beam. The reciprocating motion of the beam drives the slotting and creasing of the cardboard. As the beam moves towards the cardboard, creasing is achieved simultaneously with slotting. However, this type of mechanism has several problems: First, in existing technologies, the creasing blade is installed in a groove at the top of the slotting blade. To ensure connection strength, the thickness of the slotting blade must be greater than the length of the creasing blade. This limits the structure and size of the slotting blade to the creasing blade, making it unable to process small-width slots. Second, due to the limitations of the existing structure, creasing is prone to problems such as bursting or corrugation. More importantly, the small-batch corrugated packaging market has a high demand for the integration of printing presses and carton forming machines. Printing equipment requires the cardboard face paper to face upwards, while existing carton forming machines require the face paper to face downwards and the linerboard upwards so that the crimping knife can align the linerboard along the linerboard side for a good forming result. If the printing press is used in conjunction with the existing carton forming machine, the cardboard needs to be flipped after printing, making the process complex and inefficient. Other existing processing equipment, such as die cutters, can process with the face paper facing upwards and can process narrow slots, but these machines can only process a few standard box types and cannot process any box type like carton forming machines. Furthermore, these machines are not suitable for small-batch orders.

[0004] Therefore, a new slotting and wire-touch mechanism is needed to solve at least one of the above problems. Utility Model Content

[0027] The following description is exemplary in nature and is not intended to limit this application, application, or use. Furthermore, it is not intended to be limited by any express or implied theory presented in the foregoing description of the technical field, background art, or utility model, or the following detailed description. It should be understood that throughout the drawings, corresponding reference numerals identify similar or corresponding parts or features.

[0028] This application will now be further elaborated. In the following paragraphs, different aspects of this application are defined in more detail. Unless expressly indicated to the contrary, each aspect so defined may be combined with any other aspect(s). In particular, any feature indicated as preferred or advantageous may be combined with any other feature(s) indicated as preferred or advantageous.

[0029] To address the problems existing in the prior art, this application provides a new grooving and creasing mechanism that separates the grooving module and the creasing module, enabling it to groove and creasing the cardboard from both sides respectively.

[0030] See attached document Figure 1 To be continued Figure 5 This paper illustrates a slotting and creasing mechanism 100 according to the principles of this application. The slotting and creasing mechanism 100 includes a slotting module and a creasing module. The slotting module includes a slotting beam 110, a slotting blade 111 disposed on the slotting beam 110, a slotting lower blade mounting beam 112, and a slotting lower blade 113 disposed on the slotting lower blade mounting beam 112. The slotting module may further include a slotting blade driving mechanism 114, which is connected to the slotting blade 111, thereby driving the slotting blade 111 to move along the length direction of the slotting beam 110 to meet the slotting requirements of cardboard of various widths. Those skilled in the art will readily understand that the slotting blade driving mechanism 114 can be of various types. For example, the slotting blade driving mechanism 114 can drive the slotting blade 111 through the cooperation of a lead screw and a lead screw nut, or through the cooperation of a gear and a rack, etc., to drive the slotting blade 111 to move along the length direction of the slotting beam 110.

[0031] The creasing module includes a creasing beam 120, creasing blades 121 disposed on the creasing beam 120, and a creasing support beam 122. The creasing beam 120 can be integrally formed with the creasing blades 121, or they can be connected together by means such as threaded connections. The creasing beam 120 and the slotting beam 110 are vertically opposite each other, thus ensuring that the creasing blades 121 and grooving blades 111 are also vertically opposite each other. It should be understood that the opposite arrangement of the creasing blades 121 and grooving blades 111 means that the sides of the blades that contact the cardboard during creasing or slotting are opposite each other. This allows the cardboard to move between the grooving blades 111 and grooving blades 121 during processing, with the grooving blades 111 and grooving blades 121 respectively performing slotting and creasing on both sides of the cardboard during passage. This avoids the problem in the prior art where it is difficult to process small grooves when the grooving blades and creasing blades are placed on the same beam. The grooving cutter mounting beam 112 and the wire-contacting support beam 122 are positioned between the grooving cutter 111 and the wire-contacting cutter 121, respectively, to cooperate with the grooving cutter 111 and the wire-contacting cutter 121 to complete grooving and wire-contacting. The grooving beam 110 can be located above or below the wire-contacting beam 120.

[0032] The grooving and wire-contacting mechanism may further include a first power module, which can be connected to the grooving module and the wire-contacting module to provide them with power. For example, the first power module can be connected to the grooving crossbeam 110 of the grooving module and the wire-contacting crossbeam 120 of the wire-contacting module, so as to drive the grooving crossbeam 110 to move the grooving cutter 111 toward the grooving lower cutter 113, and drive the wire-contacting crossbeam 120 to move the wire-contacting cutter 121 toward the wire-contacting support crossbeam 120. The first power module may include one or more identical or different power mechanisms. In some embodiments, the first power module may include one or more identical power mechanisms, for example, the first power module may include two identical cam mechanisms that simultaneously provide power to both the grooving crossbeam 110 and the wire-contacting crossbeam 120 from both sides. In some embodiments, the first power module may also include two or more different power mechanisms, for example, the grooving crossbeam 110 and the wire-contacting crossbeam 120 may be driven by two different sets of cam mechanisms at their respective ends. The slotting and crimping mechanism may also include a wall panel 170, and the first power module may be mounted on the wall panel 170, or on the housing of the carton forming machine or box making machine, to fix it in place.

[0033] See attached document Figure 1 To be continued Figure 5 In some embodiments, the first power module includes cam mechanisms 130 disposed at both ends of the grooving and creasing mechanism 100. The cam mechanism 130 includes a cam assembly 131 and a connecting shaft 132 connected to the cam assembly 131. The cam mechanism 130 is connected to both ends of the grooving beam 110 and the creasing beam 120 via the connecting shaft 132. When the cam assembly 131 rotates, it drives the connecting shaft 132 to reciprocate up and down, thereby driving the grooving knife 111 and the creasing knife 121 to reciprocate vertically. The cam assemblies 131 located at both ends of the grooving and creasing mechanism 100 can be connected via a transmission shaft 133 to achieve coaxial rotation. In some embodiments, the cam mechanism 130 can be an eccentric wheel mechanism. Thus, one rotation of the cam in the cam mechanism 130 drives the grooving knife 111 and the creasing knife 121 to move from both sides of the cardboard towards the cardboard, thereby completing the grooving and creasing of the cardboard. It should be understood that the first power module may include any mechanism capable of reciprocating the grooving knife 111 and the wire-contacting knife 121, such as a cylinder, a hydraulic cylinder, or a gear and rack mechanism.

[0034] See attached document Figure 1 To be continued Figure 5In a preferred embodiment, the grooving beam 110 is located above the grooving crossbeam 120. A grooving cutter mounting beam 112 is disposed between the grooving beam 110 and the grooving crossbeam 120. The grooving cutter mounting beam 112 has a first through slot 115 along its length, and grooving cutters 113 are disposed on both sides of the first through slot 115. When the grooving cutter 111 moves toward the grooving cutter 113, the grooving cutter 111 can insert into the first through slot 115 and cooperate with the grooving cutters 113 disposed on both sides of the first through slot 115 to cut the cardboard, thereby completing the grooving of the cardboard.

[0035] The wire-contacting blade 121 is directly opposite the first through slot 115, allowing it to penetrate the first through slot 115 when moving towards the slotting lower blade mounting beam 112. A wire-contacting support beam 122 is positioned between the slotting beam 110 and the slotting lower blade mounting beam 112. The wire-contacting support beam 122 has a second through slot 123 along its length. The slotting blade 111 is directly opposite the second through slot 123, allowing it to pass through the second through slot 123 and move towards the slotting lower blade 113.

[0036] In some embodiments, the slotting cutter mounting beam 112 has side plates on both sides along its length, thus presenting a downward-opening groove shape. The side plates enhance the strength of the slotting cutter mounting beam 112. The wire-catching beam 120 is disposed in this groove, thereby saving space and making the overall structure of the slotting wire-catching mechanism 100 compact. It should be understood that the wire-catching beam 120 being disposed in this groove does not necessarily mean that the wire-catching beam 120 is completely within the groove. For example, in the attached... Figure 1 and attached Figure 2 In the embodiment shown, the main body of the line-touching beam 120 is located in the groove, while its two ends can extend out of the groove and be connected to the cam mechanism 130 through connectors.

[0037] In some embodiments, the wire-connecting support beam 122 has side plates on both sides along its length and width, thus presenting an upward-opening groove shape. The side plates enhance the strength of the wire-connecting support beam 122. The grooving cutter 111 is located in this groove, thereby saving space. Both ends of the wire-connecting support beam 122 and the grooving cutter mounting beam 112 can be directly or indirectly connected to the wall panel 170, or the housing of the carton forming machine or box making machine, or other mechanisms such as the grooving cutter mounting beam, to provide fixed support.

[0038] See attached document Figure 6A In some embodiments, the side of the second through groove 123 facing the wire-contacting knife 121 can be planar. (See attached diagram.) Figure 6BIn some preferred embodiments, the second through groove 123 facing the crimping knife 121 has protruding ribs 124 on both sides along its length. The protruding ribs 124 extend along both sides of the length of the second through groove 123, so that during the crimping process of the paperboard by the crimping knife 121, the protruding ribs 124 can support the paperboard and prevent the problem of corrugation and cracking.

[0039] See attached document Figure 1 To be continued Figure 3 In some embodiments, the slotting and creasing mechanism 100 may further include a first height adjustment module 150, which is connected to the creasing beam 120, thereby adjusting the distance of the creasing beam 120 relative to the creasing support beam 122, or its height relative to the ground, and thus adjusting the depth of the creasing knife 121 acting on the cardboard, that is, the amount of compression of the cardboard by the creasing knife 121. The slotting and creasing mechanism 100 may further include a second height adjustment module 160, which is connected to the creasing support beam 122, thereby adjusting the distance of the creasing support beam 122 relative to the creasing beam 120, or its height relative to the ground, to meet the needs of processing cardboard of different thicknesses.

[0040] In some alternative embodiments, the creasing support beam 122 includes a first body and a second body, and the slotting creasing mechanism 100 includes a second power module. The second power module can be connected to the first body and the second body, thereby driving the first body and the second body to move closer or further apart in the horizontal direction. When the first body and the second body move closer together, that is, when they come into contact, the first body and the second body form a complete creasing support beam 122. In these embodiments, when the slotting knife 111 moves toward the slotting lower knife 113, the second power module drives the first body and the second body to move away from each other, so that the slotting knife 111 passes between them; when the creasing knife 121 moves toward the creasing support beam 122, the second power module drives the first body and the second body to move closer together until they come into contact, forming a complete creasing support beam 122, thereby providing support for the cardboard during creasing.

[0041] When processing cardboard using an embodiment of the present application, the cardboard stops advancing when it reaches between the slotting lower tool mounting beam 112 and the scoring support cross beam 122 through the conveying device. At this time, the cam mechanism 130 operates. When the cam assembly 131 drives the connecting shaft 132 to move downward, the slotting knife 111 and the scoring knife 121 move downward simultaneously. During the downward movement of the slotting knife 111, it passes through the second through slot 123 to slot the cardboard. When the cam assembly 131 drives the connecting shaft 132 to move upward, the slotting knife 111 and the scoring knife 121 move upward simultaneously. During the upward movement of the scoring knife 121, it passes through the first through slot 115 to score the cardboard. After the slotting and scoring mechanism 100 of the present application completes slotting and scoring the cardboard, the cardboard continues to advance to the next process under the action of the conveying mechanism.

[0042] The slotting and scoring mechanism of the present application can effectively solve the problems existing in the prior art. First, referring to the attached Figure 7 , in the slotting and scoring mechanism in the prior art, in order to facilitate connecting the scoring knife, a boss 12 is provided on the side of the slotting knife 11 away from the cutting edge, and a groove 13 is provided on the boss 12 for installing the scoring knife, which increases the thickness of the slotting knife and makes it difficult to process slots with smaller dimensions. In the slotting and scoring mechanism 100 of the present application, the slotting knife and the scoring knife are arranged on different beams, so that the slotting knife 111 in the slotting and scoring mechanism 100 of the present application does not need to increase its thickness, and thus can be set with a smaller thickness to process slots with smaller dimensions. Second, in the slotting and scoring mechanism 1, the convex rib 124 can support the cardboard during the scoring process, preventing warping and bursting of the cardboard during scoring. Third, and more importantly, by installing the slotting knife and the scoring knife on different cross beams, slotting and scoring can be respectively performed on both sides of the cardboard, so that slotting and scoring can be realized in the way that the face paper faces upward, which is convenient for联动使用 with the printing module and improves the processing efficiency.

[0043] The present application also provides a carton making machine, which includes a slotting and scoring mechanism according to the principle of the present application, and thus has the beneficial effects brought by the slotting and scoring mechanism of the present application.

It should also be understood that one exemplary embodiment or multiple exemplary embodiments described herein are merely examples and are not intended to limit the scope, applicability, or construction of the present application in any way. On the contrary, the foregoing detailed description will provide those skilled in the art with a convenient guide for implementing one exemplary embodiment or multiple exemplary embodiments.
