Abstract
Description
Technical Field
[0001] This utility model relates to the field of carton making technology, and in particular to a parallel horizontal slotting and creasing mechanism. Background Technology
[0002] Cardboard boxes are the most widely used packaging products, typically used as wrapping materials for goods or as protective outer layers for items. During production, cardboard boxes are formed by bending cardboard. To ensure a completely sealed box, several slots are cut at the top and bottom of the cardboard to facilitate folding and sealing. The structure for slotting the cardboard is called a slotting assembly, which usually consists of an upper cutter shaft and rollers. The upper cutter shaft has slotting blades, and the cardboard is slotted by the rolling of the upper cutter shaft. Simultaneously, corresponding creases need to be applied near the slotting, which requires corresponding slotting and crease knives. Currently, slotting mechanisms on the market first use a slotting blade to slot the cardboard, and then use a crease knife to crease near the slot. The disadvantage of this operation is that the slot and crease are too close, and the crease process can easily damage the slot. In other words, the slotting blade cannot cooperate with the crease knife for transverse creases, and creases and creases cannot be performed simultaneously. This not only makes the cardboard box machine structure more complex but also affects processing efficiency. Utility Model Content
[0003] The purpose of this utility model is to design a parallel horizontal slotting and indentation mechanism to overcome the shortcomings of the above-mentioned technology.
[0004] This utility model designs a parallel horizontal grooving and indentation mechanism, including a movable mounting body. The mounting body is provided with a first tool holder, on which a grooving tool is provided. The grooving tool extends along the horizontal length direction of the mounting body and includes a cutting edge. The mounting body is also provided with an indentation tool, which is arranged parallel to the cutting edge of the grooving tool. A conveying roller is provided on the opposite side of the mounting body. The mounting body rotates or translates relative to the conveying roller, driving the grooving tool and the indentation tool to perform grooving and indentation work.
[0005] Further optimization includes a base body connected to a mounting body and extending along the lateral length of the mounting body. The top of the base body has two rows of blade segments, each row of blade segments extending along the length of the mounting body. One pair or two pairs of ends of the two rows of blade segments are integrally connected to form a closed end. The indentation tool and one blade segment of the grooving tool are arranged parallel to each other.
[0006] Further optimization involves a double-row blade section, and the closed end includes two rows of blade sections and a connecting section connecting the blade sections. When the two rows of blade segments are parallel to each other and the connecting section is convex and arc-shaped, the closed end is a U-shaped end; or, when the two rows of blade segments are parallel to each other and the connecting section is inclined relative to the blade segments, the closed end is an inclined end; or, one row of blade segments is parallel to the indentation tool, and the other row of blade segments is relatively inclined, with the connecting section and the inclined blade segments on the same straight line, the closed end is a triangular end. The three shapes of the closed ends can be freely combined in pairs to serve as the closed ends of the grooving tool.
[0007] Further optimization involves a single-row blade section, with the indentation tool arranged parallel to the blade section.
[0008] Further optimization involves making the cutting edge a straight line.
[0009] Preferably, the guide rail extends along the length of the mounting body, and the first tool holder is provided with a slider that slides with the guide rail, so that the first tool holder is slidably connected to the mounting body; the first tool holder is driven by a transmission mechanism to slide back and forth along the length of the mounting body.
[0010] Preferably, the mounting body is a crossbeam structure, the first tool holder is disposed on the crossbeam structure, the indentation tool is disposed on the crossbeam structure, and the crossbeam structure is provided with a driving mechanism to drive the crossbeam structure to translate relative to the conveyor roller, thereby realizing the translational movement of the mounting body.
[0011] Preferably, the indentation tool is slidably connected to the mounting body. The mounting body has lead screw pairs at both ends, each including a lead screw and a nut. The lead screw is vertically positioned relative to the mounting body, and the nut is slidably connected to it. The nut connects to the indentation tool to drive it to move up and down along the lead screw. A worm gear is fixed to the lead screw, and a worm is connected to it. A synchronizing rod is provided between the two worms at both ends of the mounting body. One worm is connected to a driving component, which drives the worm to rotate. The worm drives the synchronizing rod, causing both worms to rotate synchronously. The worm drives the worm wheel to rotate, which in turn drives the lead screw to rotate. The lead screw drives the nut to move up and down, and the nut drives the indentation tool to move horizontally, thus achieving the horizontal movement of the indentation tool.
[0012] Preferably, when the mounting body is a beam structure, the transmission mechanism includes a first rack structure in the same direction as the length of the mounting body, a first gear structure meshing on the first rack structure, the first gear structure being connected to a first base, a first driving device for driving the first gear structure to rotate on the first base, and the first base also connecting a slider and a first tool holder, so that the first base drives the first tool holder to slide back and forth along the length of the mounting body, thereby causing the first tool holder to drive the grooving tool to slide back and forth along the length of the mounting body.
[0013] Preferably, the mounting body is a rotatable roller structure, and the first cutter holder has a through hole in the center so that the first cutter holder is sleeved on the roller structure. The grooving cutter and the indentation cutter extend along the axial direction of the roller structure. The rotation of the roller structure drives the first cutter holder to rotate, and the first cutter holder drives the grooving cutter and the indentation cutter to rotate synchronously, thereby realizing the rotation action of the mounting body.
[0014] Preferably, the longitudinal section of the base body is inverted T-shaped, and the outer periphery of the first tool holder has a groove that extends axially through both ends. The bottom of the base body is embedded in the groove of the first tool holder. One first tool holder corresponds to two second tool holders, which are located at both ends of the first tool holder. The center of the second tool holder has an axially penetrating mounting hole. The second tool holder is fitted onto the mounting body through the mounting hole. The outer periphery of the second tool holder has a stepped surface, which includes two mutually perpendicular mounting surfaces. The end of the indentation tool is located on the stepped surface. The outer periphery of the end of the indentation tool is attached to and abuts against one of the mounting surfaces and is fixed by fasteners. The part of the indentation tool that passes through the base body abuts against one side of the base body.
[0015] Preferably, when the mounting body is a roller structure, the transmission mechanism includes a fixed beam located above the mounting body. The fixed beam is provided with a second rack structure in the same direction as the length of the mounting body. A second gear structure is meshed on the second rack structure. The second gear structure is connected to a second base. The second base is provided with a second driving device that drives the second gear structure to rotate. The bottom of the second base is provided with a downwardly retractable positioning pin. The first tool holder is provided with a positioning hole. When the positioning pin is inserted into the positioning hole, the second base and the first tool holder are fixedly connected. This causes the second base to drive the first tool holder to slide back and forth along the length of the mounting body, which in turn causes the first tool holder to drive the grooving tool to slide back and forth along the length of the mounting body.
[0016] Preferably, there are at least two first tool holders arranged side by side on the same mounting body. Each first tool holder is provided with a grooving tool and a corresponding transmission mechanism to enable the first tool holders to slide individually or synchronously.
[0017] Preferably, the cutting edges of the indentation tool and the grooving tool are at least partially abutting each other and / or at least partially parallel to each other.
[0018] The technical advantages of this invention are as follows: The mounting body is equipped with grooving and creasing knives, which are arranged side-by-side and parallel to each other. By rotating or translating the mounting body, creasing is performed simultaneously during the grooving process, ensuring that grooving and creasing are carried out concurrently. This prevents damage to the grooved surface during creasing, improving work efficiency and processing yield. Furthermore, the mounting body can perform both grooving and creasing through rotation or translation, making it suitable for various working conditions. The knife holders of the grooving knives can be individually adjusted, allowing for lateral position adjustment among multiple sets of grooving and creasing knives to simultaneously perform grooving and creasing work at different positions on the same cardboard. Therefore, the structure is not only simple and compact, improving space utilization, but also significantly increasing grooving and creasing efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0022] This utility model includes a mounting body 1, on which a first tool holder 2 is provided, and on which a grooving tool 3 is provided. The grooving tool 3 extends along the transverse length direction of the mounting body 1. The grooving tool 3 includes a base 31, which extends along the length direction of the mounting body 1. The top of the base 31 is provided with two rows or one row of blade segments 32 extending in the same direction. The bottom of the blade segments 32 is connected to the first tool holder 2, and the top of the blade segments 32 forms a serrated blade. The blade segments 32 extend along the length direction of the mounting body 1. The mounting body 1 is also provided with an indentation tool 5, which is at least partially parallel to the grooving tool 3. There are two cases: one is when the blade segment 32 is a straight blade segment, the blade segment 32 is completely parallel to the indentation tool 5; the other is when the blade segment 32 includes different linear segments such as straight segments, inclined segments, or curved segments, the blade segment 32 is partially or partially parallel to the indentation tool 5.
[0023] The cutting edge 32 of the grooving tool 3 is at least partially close to or abuts against the indentation tool 5.
[0024] When the blade segment 32 is in two rows, it is a double blade. The two rows of blade segments 32 can be parallel to each other or not parallel. The embossing knife 5 can be parallel to one of the blade segments 32. That is, the embossing knife 5 and the grooving knife 3 are in the same direction and close to each other. When the blade segment 32 is in a single row, it is a single blade. It can be set parallel to the embossing knife 5.
[0025] When the grooving knife 3 and the creasing knife 5 perform grooving and creasing work simultaneously, since the height of the creasing knife 5 blade is less than the height of the grooving knife 3 blade section 32, the cardboard is grooved first. As the mounting body 1 continues to move toward the cardboard, the creasing knife 5 then creasing the cardboard, thus achieving the processing sequence of grooving first and then creasing.
[0026] Furthermore, one or both pairs of ends of the two rows of blade segments 32 are integrally connected to form a closed end 33 to ensure the strength of the grooving blade 3 and prevent the grooving blade 3 from bending and deforming.
[0027] Furthermore, when the blade segment 32 is double-rowed, the closed end 33 includes two rows of blade segments 32 and a connecting segment 34 connecting the two blade segments 32. The shape of the closed end 33 can be three different. Figure 8These are top-view schematic diagrams of three shapes of the closed end 33. In diagram a, the two rows of cutting edge segments 32 are parallel to each other, and the connecting segment 34 is convex and arc-shaped, forming a U-shaped end. Diagram b shows an inclined closed end 33, where the two rows of cutting edge segments 32 are parallel to each other and have a length difference. The two rows of cutting edge segments 32 are connected by a connecting segment 34, which is inclined, forming an inclined end. In diagram c, one of the two cutting edge segments 32 is parallel to the indentation tool 5, while the other cutting edge segment 32 is relatively inclined, thus forming a long triangular closed end 33. Of course, the above three shapes of closed ends 33 can be freely combined in pairs as the closed ends 33 of the grooving tool 3 to achieve flexible grooving.
[0028] In another embodiment, the cutting edge segment 32 is a straight cutting edge, that is, the grooving knife is a straight-edged knife or a serrated knife with the serrations distributed in a straight line; in addition, the straight cutting edge can be segmented and combined to form the cutting edge segment 32.
[0029] A guide rail 6 extends along the length of the mounting body 1 on the mounting body 1. A slider 7 on the first tool holder 2 is slidably connected to the mounting body 1, forming a sliding engagement with the guide rail 6. The first tool holder 2 is driven by a transmission mechanism to reciprocate along the length of the mounting body 1, allowing for position adjustment relative to the mounting body 1. In this embodiment, there are two first tool holders 2, arranged side-by-side on the same mounting body 1. Each first tool holder 2 is equipped with a grooving tool 3, and each first tool holder 2 is equipped with a corresponding transmission mechanism to enable individual or synchronous sliding of the first tool holder 2, thereby adjusting the distance between the two sets of grooving tools 3 and indentation tools 5.
[0030] Below the mounting body 1 is a conveyor roller 8, typically a rubber roller, used to convey cardboard. The conveyor roller 8 is located on the opposite side of the mounting body 1 and coaxial. The mounting body 1 rotates or translates relative to the conveyor roller 8. The mounting body 1 drives the grooving knife 3 and the creasing knife 5, so that the grooving knife 3 and the creasing knife 5 achieve grooving and creasing through two motion modes: The first method involves grooving and creasing via rotation. When the mounting body 1 is a rotatable roller structure, the first knife holder 2 is fitted onto the outer wall of the roller structure. The grooving knife 3 and creasing knife 5 on the first knife holder 2 extend along the length of the roller structure. Multiple first knife holders 2 can be arranged equidistantly around the outer circumference of the roller structure, with each first knife holder 2 equipped with a corresponding grooving knife 3 and creasing knife 5. When the roller structure rotates under the drive of the driving device, the first knife holder 2 rotates relative to the conveyor roller 8. The grooving knife 3 and creasing knife 5 on the first knife holder 2 also rotate relative to the conveyor roller 8 accordingly. During rotation, the grooving knife 3 and creasing knife 5 press down on the cardboard on the conveyor roller 8, thereby sequentially grooving and creasing the cardboard.
[0031] The first method involves grooving and creasing via rotation. When the mounting body 1 is a rotatable roller structure, the first knife holder 2 is fitted onto the outer wall of the roller structure. The grooving knife 3 and creasing knife 5 on the first knife holder 2 extend along the length of the roller structure. There are at least two first knife holders 2, equidistantly distributed circumferentially along the outer perimeter of the roller structure. Each first knife holder 2 is equipped with a corresponding grooving knife 3 and creasing knife 5. When the roller structure rotates under the drive of the drive device, it causes the first knife holder 2 to rotate. The grooving knife 3 and creasing knife 5 on the first knife holder 2 also rotate relative to the conveyor roller 8. During rotation, the grooving knife 3 and creasing knife 5 press down on the cardboard on the conveyor roller 8, thereby sequentially grooving and creasing the cardboard.
[0032] The second method involves downward pressure for grooving and creasing. When the mounting body 1 is typically a beam structure, the first knife holder 2 is directly fixed to the mounting body 1 via a slider 7. When there are multiple first knife holders 2, they are arranged in a straight line along the length of the beam structure and positioned on it. Each first knife holder 2 is equipped with a corresponding grooving knife 3. A drive mechanism is provided on the beam structure, which drives the beam structure to translate, meaning the mounting body 1 can translate, thereby causing the grooving knife 3 and creasing knife 5 to move up and down. Thus, the grooving knife 3 and creasing knife 5, along with the mounting body 1, press vertically downwards onto the cardboard on the conveyor roller 8, thereby sequentially grooving and creasing the cardboard. The drive mechanism is a conventional transmission structure and will not be described in detail here.
[0033] Furthermore, a groove is provided on the crossbeam structure, and the crease knife 5 is inserted into the groove. The crease knife 5 can slide up and down along the groove. A drive component 11 is provided on the crossbeam structure, and a screw pair structure 9 is provided at both ends of the crossbeam structure. The screw pair structure 9 includes a screw and a nut. The screw is set vertically relative to the mounting body 1. The nut is slidably connected to the screw. The nut is connected to the top of the crease knife 5 to drive the crease knife 5 to slide up and down along the crossbeam structure. A worm wheel is fixed on the screw, and a worm is connected to the worm. A synchronizing rod 12 is provided between the two worms at both ends of the mounting body 1. One of the worms is connected to the drive component 11. The drive component 11 is usually a motor. The drive component 11 drives the worm to rotate. The worm drives the synchronizing rod 12 to drive the two worms to rotate synchronously. The worm drives the worm wheel to rotate. The worm wheel drives the screw to rotate. The screw drives the nut to move up and down. The nut drives the crease knife 5 to move horizontally, so that the height position of the crease knife 5 can be adjusted independently relative to the crossbeam structure, that is, the extension amount of the crease knife 5 blade, to adapt to cardboard of different thicknesses.
[0034] Furthermore, when the mounting body 1 is a rotatable roller structure, the first cutter holder 2 has a through hole 10 in the center, so that the first cutter holder 2 is sleeved on the roller structure. The grooving cutter 3 and the indentation cutter 5 extend along the axial direction of the roller structure. The rotation of the roller structure drives the first cutter holder 2 to rotate. The first cutter holder 2 drives the grooving cutter 3 and the indentation cutter 5 to rotate synchronously, thereby realizing the rotation action of the mounting body 1.
[0035] Furthermore, the longitudinal section of the base 31 is inverted T-shaped. The outer periphery of the first tool holder 2 has a groove that extends through both ends axially. The bottom of the base 31 is embedded in the groove of the first tool holder 2 and is fixed to the first tool holder 2 by fasteners. In this embodiment, one first tool holder 2 corresponds to two second tool holders 24. The two second tool holders 24 are located at both ends of the first tool holder 2. That is, the two ends of the indentation tool 5 are fixedly connected to the mounting body 1 through the second tool holders 24. The center of the second tool holder 24 has an axially extending mounting hole 241. The second tool holder 24 is sleeved on the mounting body 1 through the mounting hole 241. The outer periphery of the second tool holder 24 has a stepped surface 242. The stepped surface 242 includes two mutually perpendicular mounting surfaces 243. The end of the indentation tool 5 is located on the stepped surface 242. The outer periphery of the end of the indentation tool 5 is attached to and abuts against one of the mounting surfaces 243 and is fixed by fasteners. The part of the blade of the indentation tool 5 that passes through the base 31 abuts against one side of the base 31.
[0036] It should be noted that the embossing tool 5 can be adjusted and fixed relative to the second tool holder 24, so that the extension of the embossing tool 5 relative to the grooving tool 3 can be adjusted to adapt to different embossing requirements.
[0037] It should be noted that when there are multiple indentation knives 5, they are distributed circumferentially and equally along the outer periphery of the roller structure, just like the grooving knives 3. Both ends of each indentation knife 5 are fixedly connected to the same second knife holder 24. At this time, multiple stepped surfaces 242 are opened along the outer periphery on the second knife holder 24, and the ends of each indentation knife 5 are sequentially set on the stepped surfaces 242.
[0038] The first tool holder 2 reciprocates under the drive of the transmission mechanism. When the mounting body 1 is a crossbeam structure, the transmission mechanism includes a first rack structure 13 in the same direction as the length of the mounting body 1. A first gear structure 14 is meshed on the first rack structure 13. The first gear structure 14 is connected to a first base 15. A first driving device 16 that drives the first gear structure 14 to rotate is provided on the first base 15. The first base 15 is also connected to the slider 7 and the first tool holder 2, so that the first base 15 drives the first tool holder 2 to reciprocate along the length of the mounting body 1, thereby causing the first tool holder 2 to drive the grooving tool 3 to reciprocate along the length of the mounting body 1. When the mounting body 1 is a roller structure, the transmission mechanism includes a fixed beam 17 located above the mounting body 1. The fixed beam 17 is provided with a second rack structure 18 in the same direction as the length of the mounting body 1. A second gear structure 19 is meshed on the second rack structure 18. The second gear structure 19 is connected to a second base 20. The second base 20 is provided with a second driving device 21 that drives the second gear structure 19 to rotate. The bottom of the second base 20 is provided with a downwardly retractable positioning pin 22. Usually, the positioning pin 22 is connected to a telescopic mechanism. The telescopic end of the telescopic mechanism is connected to the positioning pin 22. The first cutter holder 2 is provided with a positioning hole 23. When the positioning pin 22 is inserted into the positioning hole 23, the second base 20 and the first cutter holder 2 are fixedly connected. This causes the second base 20 to drive the first cutter holder 2 to slide back and forth along the length of the mounting body 1, which in turn causes the first cutter holder 2 to drive the grooving cutter 3 to slide back and forth along the length of the mounting body 1.
[0039] Furthermore, when there are two or more first tool holders 2, they are arranged side by side on the same mounting body 1. Each first tool holder 2 is provided with a grooving tool 3, and each first tool holder 2 is also provided with a corresponding transmission mechanism to realize the individual or synchronous sliding of the first tool holder 2, thereby realizing the lateral position adjustment between multiple sets of grooving tools 3 and indentation tools 5, and realizing synchronous grooving and indentation.
[0040] The aforementioned transmission mechanism is a gear and rack structure, but it can also be a lead screw pair structure, a synchronous conveyor belt structure, a worm gear structure, or a chain drive structure, etc. Since these are conventional technologies, they will not be described in detail here.
[0041] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
