[0002] In the production and processing of packaging boxes, the cutting process is a crucial step, requiring the rolls of packaging box material to be precisely cut to the specified dimensions.

[0003] Currently, traditional packaging box cutting operations mostly rely on manual feeding. Operators need to move the packaging box material to the cutting equipment and manually adjust its position to ensure cutting accuracy. This method not only consumes a lot of manpower and time, and is labor-intensive, but the instability of manual operation can also easily lead to deviations in cutting dimensions, affecting product quality. In addition, during the cutting process, the packaging box material is prone to shifting, further reducing cutting accuracy and increasing material waste. Utility Model Content

[0005] As a further improvement to the above technical solution, a material guiding assembly is also included. The material guiding assembly includes a mounting shell and two sets of limiting base plates symmetrically arranged on the top side of the cutting platform. The top of the limiting base plate has a limiting top plate. An adjustment part is provided in the mounting shell. The adjustment part is used to drive the two sets of limiting base plates to move towards each other or away from each other.

[0006] As a further improvement to the above technical solution, the mounting shell is fixedly connected to the frame of the conveyor body. The adjustment part includes a second drive motor installed inside one side of the mounting shell. The output shaft of the second drive motor is connected to a threaded rod. Two sets of nut sleeves are symmetrically threaded on the threaded rod. The bottom end of the nut sleeve is slidably connected to a limiting groove opened inside the mounting shell. One side of the nut sleeve is connected to an L-shaped movable frame. One end of the L-shaped movable frame extends movably through to the outside of the mounting shell and is fixedly connected to the adjacent limiting base plate.

[0007] As a further improvement to the above technical solution, the opening ends of the first strip guide sleeve and the second strip guide sleeve are arranged facing each other, and a pressure sensor is installed at the sealing end of the second strip guide sleeve on the side away from the opening end.

[0008] As a further improvement to the above technical solution, the box material feeding part includes a mounting frame, a drive motor is mounted on one side of the mounting frame, and the output shaft of the drive motor is connected to a conveying roller, on which the box material is wound.

[0009] As a further improvement to the above technical solution, the cutting section includes a mounting top frame, which is mounted on the frame of the conveyor body.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Example For cutting equipment used in packaging box processing, please refer to [reference needed]. Figures 1-3 It includes the conveyor body 1, which serves as the main carrier for conveying packaging box materials. Its frame is made of high-strength steel to ensure the stability of the overall structure.

[0017] A first strip guide sleeve 100 is welded to one side of the feed end of the conveyor body 1. The cross-section of the first strip guide sleeve 100 is rectangular and its inner wall is smooth. It can play a preliminary guiding role for the packaging box material entering the conveyor body 1 and prevent the packaging box material from deviating when entering the conveyor track.

[0018] A second strip-shaped guide sleeve 6 is bolted to one side of the discharge end of the conveyor body 1. The open ends of the first strip-shaped guide sleeve 100 and the second strip-shaped guide sleeve 6 are arranged facing each other. This arrangement allows the packaging material to maintain a stable conveying path under the combined action of the two guide sleeves. A pressure sensor 61 is installed at the sealed end of the second strip-shaped guide sleeve 6, away from the open end. The pressure sensor 61 is a high-precision piezoelectric sensor, which can accurately detect the pressure exerted on it by the end of the packaging material.

[0019] A cutting platform 4 is provided on the top side of the conveyor body 1 near the second strip guide sleeve 6. The side of the cutting platform 4 is connected to the frame of the conveyor body 1 via a connecting bracket. The connecting bracket is welded to both the frame and the cutting platform 4 to ensure that the cutting platform 4 does not shake during the cutting process. The top surface of the cutting platform 4 is inclined downwards on the side near the first strip guide sleeve 100, with an inclination angle of 15-30 degrees, which facilitates the feeding of packaging box material onto the top surface of the cutting platform 4 for cutting.

[0020] The first strip guide sleeve 100 has a box material feeding part on the side away from the conveyor body 1. The box material feeding part includes a mounting bracket 2, which can be fixed to the ground by expansion bolts. A drive motor 21 is mounted on one side of the mounting bracket 2 via a motor base. The output shaft of the drive motor 21 is connected to a conveying roller 22 via a coupling. The box material is wound on the conveying roller 22. When the drive motor 21 is working, it drives the conveying roller 22 to rotate, thereby realizing the automatic feeding of the packaging box material.

[0021] A vertically movable cutting section is provided above the cutting platform 4. The cutting section includes a mounting frame 3, which is bolted to the frame of the conveyor body 1. An electric telescopic rod 31 is mounted on the bottom of the mounting frame 3 via a flange. The bottom output shaft of the electric telescopic rod 31 is bolted to a cutting blade 32. The cutting blade 32 is made of high-strength alloy material with a sharp blade to ensure smooth cutting.

[0022] The device also includes a material guiding assembly, which comprises a mounting shell 5 and two sets of limiting base plates 52 symmetrically arranged on the top side of the cutting platform 4. The mounting shell 5 is fixedly connected to the frame of the conveyor body 1 by bolts. The interior of the mounting shell 5 is hollow, providing space for the installation of the adjustment unit. A limiting top plate 53 is welded to the top of the limiting base plate 52. The limiting base plate 52 and the limiting top plate 53 form a U-shaped limiting space, which can limit the packaging box material from the top, bottom and sides.

[0023] The mounting housing 5 is equipped with an adjustment unit, which is used to drive the two sets of limiting base plates 52 to move towards or away from each other. The adjustment unit includes a second drive motor 54 installed inside one side of the mounting housing 5. The second drive motor 54 is fixed to the inner wall of the mounting housing 5 by a motor mount. The output shaft of the second drive motor 54 is connected to a threaded rod 55 through a coupling. The two ends of the threaded rod 55 are mounted on the inner wall of the mounting housing 5 through bearing seats. The threaded rod 55 has symmetrical threads with opposite directions of rotation.

[0024] Two sets of nut sleeves 56 are symmetrically threaded onto the threaded rod 55. The bottom end of the nut sleeve 56 is slidably connected to a limiting groove 50 inside the mounting shell 5. The limiting groove 50 guides and limits the movement of the nut sleeve 56, preventing the nut sleeve 56 from rotating with the threaded rod 55. An L-shaped movable frame 51 is welded to one side of the nut sleeve 56. One end of the L-shaped movable frame 51 extends through to the outside of the mounting shell 5 and is fixedly connected to the adjacent limiting base plate 52 by bolts. When the threaded rod 55 rotates, the two sets of nut sleeves 56 will drive the L-shaped movable frame 51 and the limiting base plate 52 to move towards or away from each other under the action of the limiting groove 50, thereby accommodating packaging box materials of different widths.

[0025] The device also includes a controller, which is a PLC controller, model S7-200. The conveyor body 1, drive motor 1 21, electric telescopic rod 31, drive motor 2 54 and pressure sensor 61 are all connected to the controller through wires to realize the automated control of the device.

[0026] Working principle: First, the packaging material is wound around the conveyor roller 22, with one end passing through the first strip guide sleeve 100 and then guided to the top of the conveyor body 1. The controller starts the conveyor body 1 and the drive motor 21. Under the combined action of the conveyor body 1 and the conveyor roller 22, the packaging material is conveyed to the cutting platform 4. During the conveying process, according to the width of the packaging material, the controller controls the drive motor 54 to work. The drive motor 54 drives the threaded rod 55 to rotate, causing the two sets of nut sleeves 56 to move the L-shaped movable frame 51 and the limiting base plate 52 under the guidance of the limiting groove 50. The distance between the two sets of limiting base plates 52 is adjusted to limit and guide the packaging material.

[0027] The tail end of the packaging material continues to be conveyed into the second strip guide sleeve 6 until its tail end contacts the pressure sensor 61. The pressure sensor 61 transmits the detected pressure signal to the controller. When the pressure reaches a preset threshold, the controller controls the conveyor body 1 and drive motor 21 to stop running. Subsequently, the controller controls the electric telescopic rod 31 to extend, driving the cutting blade 32 to move downward to cut the packaging material. After cutting is completed, the electric telescopic rod 31 retracts, driving the cutting blade 32 to reset. The operator removes the cut packaging material from the second strip guide sleeve 6, and then the controller controls the conveyor body 1 and drive motor 21 to start again for the next cutting cycle.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
