Description

Technical Field

[0001] This utility model belongs to the technical field of cardboard box processing equipment, and specifically relates to a cutting device for cardboard box processing. Background Technology

[0002] Existing cardboard box cutting equipment mainly uses mechanical cutters. Mechanical cutter cutting devices are simple in structure, low in cost, and can quickly complete cutting tasks. They are suitable for cardboard box production with low precision requirements and uniform specifications. The mechanical structure is a fundamental component of corrugated cardboard box cutting machines, but its failure frequency is relatively high. For example, cutter wear is a common problem. During prolonged cutting, the cutter continuously rubs against the corrugated cardboard, gradually dulling the blade. In actual production, when the edges of the cut cardboard boxes are rough or uneven, it is very likely due to cutter wear. In addition, the cutter position is relatively fixed, making it impossible to precisely control the cutting degree as needed, and thus unable to meet the requirements of complex cardboard box cutting and forming.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a cardboard box cutting mechanism [201410452367.7], which includes a paper cutter body with a horizontal platform and a main support. The main support frame is equipped with a positioning shaft and a roller shaft. A roller is mounted on the roller shaft through a roller mounting seat. The paper cutter body is equipped with a first conveyor belt and a second conveyor belt with reverse transmission at the top and bottom. A protective cover is provided on the side of the paper cutter body near the positioning shaft. Two guide guards are provided on the first conveyor belt. A fan and an exhaust pipe are also provided on the upper surface of the paper cutter body near the main support.

[0004] The above solution has solved the problem of high failure rate of cutting equipment to a certain extent, but it still has many shortcomings, such as the inconvenience of adjusting the blade direction. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a reasonably designed cutting device for carton processing with flexible adjustment of the blade's orientation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cutting device for carton processing, including a knife holder, a cutting head connected to the knife holder via a quick-release assembly, an adapter connected to the knife holder, a lifting assembly that is linked to the cutting head installed between the knife holder and the adapter, and a flipping assembly that is linked to the cutting head installed inside the knife holder.

[0021] In the figure, the components are: blade holder 1, quick release assembly 2, clamping bolt 21, clamping block 22, cutting blade head 3, adapter seat 4, adapter column 41, adapter groove 42, limit wheel 43, lifting assembly 5, lifting motor 51, eccentric wheel 52, eccentric connecting rod 53, flipping assembly 6, flipping motor 61, flipping connecting rod 62, and blade head mounting bracket 63. Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-4 As shown, a cutting device for carton processing includes a knife holder 1, a cutting head 3 connected to the knife holder 1 via a quick-release assembly 2, an adapter 4 connected to the knife holder 1 and mounted on a carton processing system, a lifting assembly 5 that is linked to the cutting head 3 and is installed between the knife holder 1 and the adapter 4 to adjust the height of the cutting head 3, and a flipping assembly 6 that is linked to the cutting head 3 and is installed inside the knife holder 1 to adjust the blade orientation and ensure that the tilt angle is adapted to the cardboard conveying trajectory.

[0024] Specifically, the blade holder 1 is made of alloy material and is cylindrical. The blade holder 1 has an internal cavity for housing the cutting blade 3, which provides effective protection for the cutting blade 3 when not in operation. The cutting blade 3 is installed at the lower end of the blade holder 1, and the adapter 4 is slidably connected to the upper end of the blade holder 1.

[0025] Specifically, the lifting assembly 5 includes a lifting motor 51 mounted within the adapter 4, typically a high-response servo motor or stepper motor. The output of the lifting motor 51 is connected to the cutter holder 1 via an eccentric wheel 52 and an eccentric connecting rod 53. This mechanism efficiently converts the rotational motion of the lifting motor 51 into the linear lifting motion of the cutter holder 1, and the cutting stroke can be flexibly controlled by adjusting the eccentricity. A limit guide rail is provided between the cutter holder 1 and the adapter 4 to precisely constrain the movement trajectory of the cutter holder 1 and withstand the cutting reaction force.

[0026] Furthermore, the flipping assembly 6 includes a flipping motor 61 installed inside the cutter holder 1, typically a miniaturized, high-torque DC or stepper motor. The output of the flipping motor 61 is movably connected to the cutter head mounting bracket 63 via a flipping linkage 62, enabling the flipping motor 61 to drive the cutter head mounting bracket 63 to swing at an angle. The cutter head mounting bracket 63 is movably connected to the lower end of the cutter holder 1, ensuring that the cutting cutter head 3 can perform a stable and reliable flipping action around a fixed axis to match the cutting line requirements at different angles.

[0027] Furthermore, the quick-release assembly 2 includes a clamping bolt 21 that is threadedly connected to the cutter head mounting bracket 63. The cutting head 3 achieves rapid initial positioning with the cutter head mounting bracket 63 through a positioning groove or boss on its top. The cutting head 3 is pressed against the clamping block 22 at the end of the clamping bolt 21. This design significantly reduces the tools and time required to replace the cutting head 3 and improves production flexibility.

[0028] In addition, the upper end of the adapter 4 is provided with an adapter column 41 with a cross or star-shaped cross section, providing a multi-directional, high-rigidity installation interface, which facilitates the quick adaptation of the device to different processing equipment or robotic arm ends. The adapter column 41 has several adapter grooves 42 arranged symmetrically along the axis, which facilitates quick adjustment and locking of height and angle using standard pins or locking bolts.

[0029] Meanwhile, the cutter holder 1 is connected to limiting wheels 43 located on both sides of the cutting head 3, and the central axes of the limiting wheels 43 coincide. During the cutting process, the limiting wheels 43 roll close to the edge of the paperboard or the preset guide rail, playing a key role in accurately guiding the movement trajectory of the cutter holder 1 and preventing the cutting from going astray. Their position can usually be finely adjusted to adapt to cardboard of different thicknesses.

[0030] As can be seen, the cutting head 3 is slanted trapezoidal with rounded corners at the front and rear ends of the blade. The slanted trapezoidal design facilitates cutting into the cardboard and reduces resistance. The rounded corners at the front and rear ends of the blade effectively prevent scratches or tears on the cardboard surface at the start and end of the cutting, ensuring the smoothness of the cut surface.

[0031] It is evident that a pressure sensor is installed between the cutter holder 1 and the adapter 4 to monitor the pressure changes during the cutting process in real time, and the signal is fed back to the control system to achieve closed-loop control of the cutting depth.

[0032] Preferably, the cutter holder 1 is equipped with a photoelectric sensor adjacent to the cutting head 3 to detect whether there is cardboard near the cutting head, accurately sense the edge position of the cardboard or measure the change in the thickness of the cardboard, and provide key signals for the control system such as automatic triggering of cutting, adaptive adjustment of the cutting head height and material shortage alarm.

[0033] In summary, the principle of this embodiment is as follows: the lifting assembly 5 is driven by the lifting motor 51 inside the adapter 4, which drives the eccentric wheel 52 and the eccentric connecting rod 53 to precisely convert the rotational motion into the vertical reciprocating motion of the blade holder 1, thereby driving the cutting blade head 3 to perform downward cutting and lifting actions. The limit guide rail ensures the stability of the motion trajectory. The flipping assembly 6 is driven by another flipping motor 61 inside the blade holder 1, which drives the blade head mounting bracket 63 to rotate around the pivot through the flipping connecting rod 62, thereby precisely adjusting the cutting angle of the cutting blade head 3 to adapt to different cutting needs.

[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0035] Although this document frequently uses terms such as blade holder 1, quick-release assembly 2, clamping bolt 21, clamping block 22, cutting blade head 3, adapter seat 4, adapter column 41, adapter groove 42, limit wheel 43, lifting assembly 5, lifting motor 51, eccentric wheel 52, eccentric connecting rod 53, flipping assembly 6, flipping motor 61, flipping connecting rod 62, and blade head mounting bracket 63, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
