Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, and in particular to a cutting device for cardboard box production. Background Technology

[0002] The production of cardboard boxes involves multiple processes, including raw material processing, printing, die-cutting, and forming. First, corrugated cardboard is used as raw material and cut into cardboard pieces of the correct size by a cutting machine. Then, patterns, text, or logos are printed on the surface of the cardboard by a printing machine. After printing, the cardboard enters the die-cutting stage, where the die-cutting machine creases and cuts the cardboard according to preset specifications to form the unfolded outline of the cardboard box. Next, the die-cut cardboard is folded along the creases by a folding machine to form the sides and bottom. Finally, the joints are glued or stapled by a gluing machine or a stapling machine to form a complete cardboard box. Throughout the entire production process, the precision of cutting and forming directly affects the sealing performance and load-bearing capacity of the cardboard box, while the adaptability to different cardboard box specifications determines the flexibility of the production line.

[0003] Currently, in the cardboard box production process, the cutting device processes the cardboard using molds or knives of fixed size to ensure the cutting accuracy of cardboard boxes of specific specifications. Traditional die-cutting machines can cut cardboard boxes of different lengths and widths by changing die-cutting plates of different sizes, which to some extent meets the needs of multi-specification production. However, this method requires machine shutdown when changing die-cutting plates, and operators need to manually disassemble the old mold and calibrate the position of the new mold, which seriously affects the continuity of production. Moreover, the size of the mold is fixed, and for non-standard cardboard boxes, special molds need to be customized, which increases production costs and inventory pressure.

[0004] When installing new molds, the precision needs to be manually adjusted. This process relies on the operator's experience, which leads to deviations in the size of the cut cartons. At the same time, the relative position of the cutter and the cardboard lacks real-time positioning calibration. When the carton specifications are changed, improper adjustment will cause cutting offset, resulting in material waste. This makes it difficult for the existing equipment to efficiently respond to the production needs of small batches and multiple specifications of cartons, which restricts the flexibility of the production line and the improvement of production efficiency. Utility Model Content

[0034] The cutting mechanism 5 includes two mounting bases 51, and a cutter 52 is fixedly connected to the bottom of each mounting base 51.

[0035] Specifically, the cutter 52 is fixedly connected to the bottom of the two mounting seats 51 of the cutting mechanism 5, and is used to perform the cutting operation on the carton body 2; the top rear side of the workbench 1 has adjustment grooves 53 on the left and right ends, and the bottom rear side is fixed with a bidirectional telescopic rod 54, the left and right ends of which are fixedly connected to the inner side of the two mounting seats 51 respectively; the top front and rear sides of the two mounting seats 51 are fixed with sliders 55, which are correspondingly slidably connected in the two sliding grooves 56 opened on the bottom rear side of the workbench 1; the bottom of the workbench 1 is fixed with a protective shell 6, which adopts a conical design.

[0036] When the bidirectional telescopic rod 54 extends or retracts, it drives the mounting seats 51 on the left and right sides to move in opposite directions or in opposite directions in the horizontal direction. During the movement of the mounting seats 51, the top slider 55 slides in the slide groove 56 to provide guidance and limit for the movement of the mounting seats 51, ensuring that it moves smoothly in a straight line. After the position of the mounting seats 51 is adjusted, the cutter 52 extends into the workbench 1 through the adjustment groove 53 to cut the carton body 2 placed on the top of the workbench 1.

[0037] The length and width of the adjustment groove 53 are designed according to the dimensions of the mounting base 51 and the cutter 52 to ensure that the cutter 52 can pass smoothly and reach the cutting position; the extension stroke of the bidirectional telescopic rod 54 is set according to the width of the carton body 2 of different specifications, which can adapt to the cutting needs of various sizes; the matching clearance between the slider 55 and the slide groove 56 ensures that the mounting base 51 slides smoothly and limits its displacement in the non-adjusted state.

[0038] The protective shell 6 is installed outside the cutting mechanism 5 to prevent paper scraps and debris generated during the cutting process from flying everywhere; its conical design at the bottom allows scattered paper scraps to slide down the slope to a concentrated area under the action of gravity, making it easy to clean; the material of the protective shell 6 has a certain strength to resist accidental collisions with the cutter 52 and protect the key components of the cutting mechanism 5.

[0039] The lateral limiting mechanism 3 pushes the carton body 2 of different specifications to the top center of the workbench 1 to ensure that the carton body 2 is in the cutting position; the pressing mechanism 4 fixes the carton body 2 to prevent the carton body 2 from moving during cutting and affecting the cutting accuracy; the cutting mechanism 5 adjusts the position of the mounting base 51 through the bidirectional telescopic rod 54, and drives the cutter 52 to cut the carton body 2; thus achieving the effect of flexibly adapting to different specifications of carton body 2 while performing precise cutting in the carton production and processing scenario.

The two U-shaped push plates 34 are slidably connected inside the two stroke grooves 35. Arc-shaped clamping plates 36 are fixedly connected to the inner sides of each of the two U-shaped push plates 34. The front and rear ends of the two arc-shaped clamping plates 36 are designed with inclination angles, and the outer surfaces of the two arc-shaped clamping plates 36 are designed with rounded edges.

A laser head 442 is fixedly connected to the bottom of the frame 41. The pressing mechanism 4 also includes multiple diagonal braces 45, which are fixedly connected to the front and rear sides of the top of the pressure plate 43 respectively. The top ends of the multiple diagonal braces 45 are fixedly connected to the outside of the electric telescopic rods 42 respectively.

[0041] Specifically, the bidirectional motor 31 of the lateral limiting mechanism 3 is fixed to the front bottom of the workbench 1, and threaded rods 32 are fixed to both the left and right ends; sliding seats 33 are fixed to the left and right ends of the front bottom of the workbench 1, and the two threaded rods 32 are rotatably connected to the inside of the sliding seats 33; U-shaped push plates 34 are slidably connected to the top of the two sliding seats 33, and the U-shaped push plates 34 pass through the stroke grooves 35 opened at the left and right ends of the front top of the workbench 1; arc-shaped clamping plates 36 are fixed to the inner side of the two U-shaped push plates 34, and the front and rear ends of the arc-shaped clamping plates 36 adopt an inclined design, and the outside adopts a smooth design; when the bidirectional motor 31 drives the two threaded rods 32 to rotate synchronously, it drives the U-shaped push plates 34 to move towards or away from each other along the stroke grooves 35, and the arc-shaped clamping plates 36 move closer to or away from the carton body 2 accordingly; when the arc-shaped clamping plates 36 contact the carton body 2, its inclined design and smooth surface can avoid scratching the carton, while ensuring stable clamping of carton bodies 2 of different specifications;

[0042] The gantry frame 41 of the pressing mechanism 4 is fixed to the top left and right ends of the workbench 1. Electric telescopic rods 42 are fixed to the top left and right sides, and the bottom end is connected to the pressure plate 43. The front end of the pressure plate 43 adopts an upward tilt design, and the outside adopts a smooth design. A positioning component 44 is set in the center of the top of the gantry frame 41, including a laser 441 and a laser head 442. The front and rear sides of the top of the pressure plate 43 are fixed with diagonal braces 45, and the top end is connected to the outside of the electric telescopic rod 42. When the electric telescopic rod 42 extends and retracts, it drives the pressure plate 43 to rise and fall, thereby pressing and fixing the carton body 2. The tilt design of the pressure plate 43 makes it easy to avoid the edge of the carton body 2 during the descent, and the smooth surface prevents damage to the carton. The diagonal braces 45 enhance the structural stability of the pressure plate 43 and ensure uniform force during the pressing process. The laser 441 and the laser head 442 cooperate to provide a positioning reference for the cutting position.

[0043] The cutter 52 is fixed to the bottom of the two mounting seats 51 of the cutting mechanism 5. An adjustment groove 53 is opened on the rear side of the top of the workbench 1, and a bidirectional telescopic rod 54 is fixed on the rear side of the bottom. The left and right ends of the rod are respectively connected to the inner side of the mounting seat 51. The front and rear sides of the top of the mounting seat 51 are fixed to the slider 55, which is slidably connected to the slide groove 56 at the bottom of the workbench 1. The protective shell 6 is fixed to the bottom of the workbench 1 and has a tapered design at the bottom. When the bidirectional telescopic rod 54 extends and retracts, it drives the mounting seat 51 to move along the slide groove 56. The cutter 52 is adjusted to a cutting position that matches the carton body 2 through the adjustment groove 53. During the cutting process, the protective shell 6 prevents paper scraps from splashing, and the tapered bottom guides the paper scraps to slide into the concentrated area.

[0044] The width of the travel groove 35 is adapted to the thickness of the U-shaped push plate 34 to ensure smooth sliding of the U-shaped push plate 34; the thread direction of the threaded rod 32 is matched with the rotation direction of the bidirectional motor 31 to realize the synchronous movement of the U-shaped push plate 34 towards or away from each other; the travel of the electric telescopic rod 42 meets the pressing requirements of carton bodies 2 of different thicknesses; the fit clearance between the slider 55 and the slide groove 56 ensures the smooth movement of the mounting base 51.

[0045] The lateral limiting mechanism 3 drives the threaded rod 32 via the bidirectional motor 31, which in turn drives the arc-shaped clamping plate 36 to achieve the centering positioning of the carton body 2; the pressing mechanism 4 drives the pressure plate 43 via the electric telescopic rod 42, which, together with the positioning component 44, completes the pressing and cutting positioning of the carton body 2; the cutting mechanism 5 adjusts the position of the cutter 52 via the bidirectional telescopic rod 54 to achieve precise cutting of carton bodies 2 of different specifications; the protective shell 6 collects the paper scraps generated during cutting;

[0046] The bidirectional motor 31 and threaded rod 32 of the lateral limiting mechanism 3 drive the arc-shaped clamping plate 36 to be positioned, and the electric telescopic rod 42 of the pressing mechanism 4 presses against the pressure plate 43, so as to achieve the effect of automatic adaptation to different specifications of cartons on the carton production line, and complete the precise positioning, stable pressing and efficient cutting.

[0047] Working principle: The workbench 1 serves as the basic load-bearing structure of the device. Its top front side is used to place the carton body 2, the bottom front side is equipped with a lateral limiting mechanism 3, the top is equipped with a pressing mechanism 4, the bottom rear side is arranged with a cutting mechanism 5, and the bottom is fixed with a protective shell 6. The table surface of the workbench 1 is kept flat, providing a stable placement plane for the carton body 2. Its structural strength is sufficient to withstand the pressure applied by the pressing mechanism 4 and the vibration generated by the cutting mechanism 5 during operation.

[0048] The bidirectional motor 31 of the lateral limiting mechanism 3 is fixed to the front bottom of the workbench 1, and the left and right ends are respectively connected to threaded rods 32; the sliding seats 33 at the left and right ends of the front bottom of the workbench 1 provide rotational support for the threaded rods 32; the U-shaped push plate 34 is slidably connected to the top of the sliding seat 33 and passes through the stroke groove 35 on the front top of the workbench 1; the inner side of the U-shaped push plate 34 is fixed with an arc-shaped clamping plate 36; when the bidirectional motor 31 starts, it drives the two threaded rods 32 to rotate synchronously. Since the threaded rods 32 and the U-shaped push plate 34 are threadedly engaged, the U-shaped push plate 34 moves towards or away from each other along the stroke groove 35; when moving towards each other, the arc-shaped clamping plates 36 on both sides gradually approach the carton body 2, and with the tilting angle design of its front and rear ends, guide the carton body 2 to move towards the center of the top of the workbench 1 until the arc-shaped clamping plates 36 on both sides fit against the side of the carton body 2; the smooth surface of the arc-shaped clamping plate 36 avoids scratching the carton during the pushing process, and can be adapted to the size of different specifications of carton body 2 to achieve center positioning;

[0049] The gantry frame 41 of the pressing mechanism 4 is fixed to the top left and right ends of the workbench 1. The bottom ends of the electric telescopic rods 42 on the top left and right sides are connected to the pressure plate 43. The positioning component 44 at the top center of the gantry frame 41 includes a laser 441 and a laser head 442. The diagonal braces 45 on the front and rear sides of the top of the pressure plate 43 are connected to the outside of the electric telescopic rods 42. After the carton body 2 is positioned by the lateral limiting mechanism 3, the electric telescopic rod 42 extends, driving the pressure plate 43 to descend. The upward tilt angle design at the front end of the pressure plate 43 allows it to avoid the edge of the carton body 2 during descent and smoothly reach the pressing position. After the pressure plate 43 is attached to the top of the carton body 2, the electric telescopic rod 42 maintains pressure to fix the carton. The diagonal braces 45 enhance the rigidity of the pressure plate 43, preventing it from deforming during the pressing process and ensuring uniform force. At the same time, the laser 441 emits a laser, which is focused by the laser head 442 to form a cutting positioning reference line on the surface of the carton body 2, providing a position reference for subsequent cutting operations.

[0050] The cutter 52 is fixed to the bottom of the two mounting seats 51 of the cutting mechanism 5. The sliders 55 on the front and rear sides of the top are slidably connected to the slide grooves 56 on the rear side of the bottom of the worktable 1. The adjustment groove 53 on the rear side of the top of the worktable 1 provides a lifting channel for the cutter 52. The bidirectional telescopic rod 54 on the rear side of the bottom connects to the inner side of the two mounting seats 51. According to the specifications of the carton body 2, the bidirectional telescopic rod 54 extends and retracts, driving the mounting seats 51 to move horizontally along the slide grooves 56. The cooperation between the sliders 55 and the slide grooves 56 provides guidance and limit for the movement of the mounting seats 51, ensuring its smooth linear movement. When the mounting seats 51 move to the predetermined position, the cutter 52 rises above the worktable 1 through the adjustment grooves 53 to cut the carton body 2 in the fixed state.

[0051] The protective shell 6 is fixed to the bottom of the workbench 1 and covers the cutting mechanism 5. The conical design at the bottom guides the paper scraps and debris generated during the cutting process to slide down the inclined plane to the concentrated area under the action of gravity. The material of the protective shell 6 has a certain strength, which can prevent the cutter 52 from being damaged by accidental collision, while blocking the paper scraps from flying and keeping the working environment clean.

[0052] In actual operation, the carton body 2 is first placed on the front of the top of the workbench 1. The bidirectional motor 31 of the lateral limiting mechanism 3 is started, and the arc-shaped clamps 36 on both sides push the carton body 2 to the center of the top of the workbench 1. Then, the electric telescopic rod 42 of the pressing mechanism 4 drives the pressure plate 43 to descend, fix the carton body 2, and determine the cutting position through the positioning component 44. Subsequently, the bidirectional telescopic rod 54 of the cutting mechanism 5 adjusts the position of the mounting base 51 so that the cutter 52 is aligned with the cutting area to complete the cutting operation. The paper scraps generated by cutting are collected by the protective shell 6.

[0053] The dimensions of the travel groove 35 are adapted to the U-shaped push plate 34 to ensure smooth sliding; the thread parameters of the threaded rod 32 are matched with the speed of the bidirectional motor 31 to achieve precise synchronous movement of the U-shaped push plate 34; the extension stroke of the electric telescopic rod 42 can be adjusted according to the thickness of the carton body 2 to ensure stable pressing; the matching accuracy of the slider 55 and the slide groove 56 ensures accurate positioning of the mounting base 51.

[0054] The bidirectional motor 31 and threaded rod 32 of the lateral limiting mechanism 3 drive the arc-shaped clamping plate 36 to achieve the centering positioning of the carton body 2. The electric telescopic rod 42 of the pressing mechanism 4 and the pressure plate 43, together with the positioning component 44, complete the pressing and cutting positioning. The bidirectional telescopic rod 54 of the cutting mechanism 5 adjusts the position of the cutter 52 for precise cutting. The protective shell 6 collects the cutting waste, realizing the automated, efficient and precise completion of the cutting operation of cartons of different specifications on the carton production line, while maintaining a clean and orderly production environment.
