Description

Technical Field

[0001] This utility model relates to the field of packaging box production technology, and in particular to a paper slitting machine for packaging box production. Background Technology

[0002] An existing paper slitting machine for packaging box production, with publication number CN 221233189 U, inputs cardboard to be slit from a conveyor table located on one side of two arc-shaped receiving plates. Two servo motors drive an inner support shaft and guide belt below them. When the cardboard enters the arc-shaped receiving plates and contacts the guide belt, it is guided by the guide belt to the area between two limiting plates, thus preventing the cardboard from getting stuck at the input of the conveyor belt or deviating from the conveyor belt. After the cardboard runs on the conveyor belt and enters between the two limiting plates, it is finally output from the end of the conveyor belt. At this point, a second motor drives the slitting blades to rotate at high speed, while a first motor drives the screw, causing the upper slide to move from one side of the conveyor table cavity to the other, allowing the slitting blades to slit the cardboard from one side to the other. However, during the slitting process, the cardboard may wobble as the slitting blades move, resulting in uneven slitting and affecting the quality of subsequent processing. Utility Model Content

[0003] The purpose of this invention is to provide a paper slitting machine for packaging box production in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A paper slitting machine for packaging box production includes a conveying support mechanism, which includes a support frame with conveying components on both sides. A guide component is provided on the conveying component at the feeding end. The machine also includes a slitting mechanism for cutting cardboard, located between the conveying components. The slitting mechanism includes a beam frame on the support frame, with a cylinder and guide column fixed to the upper end of the beam frame. A mounting plate is fixed to the lower end of the cylinder and guide column. An upper cutter is located at the lower end of the mounting plate. An elastic pressing component is located on the mounting plate outside the upper cutter. A support plate is located on the support frame below the upper cutter, with a lower cutter mounted on the upper end of the support plate. The elastic pressing component includes guide rods vertically spaced on the mounting plate, with a pressure frame fixed to the lower end of each guide rod. A spring is sleeved on the guide rod above the pressure frame.

[0006] Further configuration: The conveying assembly includes an active roller and an auxiliary roller arranged on both sides of the slitting mechanism. The auxiliary roller is arranged closer to the slitting mechanism. A conveyor belt is installed on the active roller and the auxiliary roller. A drive sprocket is fixedly connected to one end of the auxiliary roller. A chain is sleeved on the drive sprocket. A reduction motor is connected to one of the active rollers.

[0007] Further configuration: The active roller and auxiliary roller are rotatably connected to the support frame, and the pressure frame is located on the upper side of the two auxiliary rollers.

[0008] Further configuration: The guide assembly is arranged opposite to the front and rear of the conveying assembly at the feed end. The guide assembly includes an electric telescopic rod, and the end of the electric telescopic rod is fixed with a guide plate on the conveying assembly.

[0009] Further details: The guide column is slidably connected to the beam frame, and the guide rod is slidably connected to the mounting plate.

[0010] Further settings: The highest point of the lower cutter is flush with the upper cutting surface of the conveyor belt.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The cardboard is conveyed by the conveying support mechanism and then aligned by the guiding component before entering the slitting mechanism. The cylinder of the slitting mechanism pushes the mounting plate downward under the limit of the guide column. The pressure frame first contacts the cardboard. As the mounting plate continues to move downward, the guide rod moves upward, and the pressure frame squeezes the spring on the outside of the guide rod. At the same time, the pressure frame holds the cardboard until the upper cutter contacts the cardboard, forming a slitting action with the lower cutter. This ensures that the pressure frame holds and fixes both sides of the cardboard during slitting, improving the quality of cardboard slitting. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-5 As shown, a paper slitting machine for packaging box production includes a conveying support mechanism, which includes a support frame 11. Conveying components are provided on both sides of the support frame 11. A guide component is provided on the conveying component at the feeding end. The machine also includes a slitting mechanism for cutting paperboard, which is provided between the conveying components.

[0025] In this embodiment, the conveying assembly includes an active roller 12 and an auxiliary roller 13 disposed on both sides of the slitting mechanism. The auxiliary roller 13 is disposed closer to the slitting mechanism. A conveyor belt 15 is mounted on the active roller 12 and the auxiliary roller 13. A transmission sprocket 16 is fixedly connected to one end of the auxiliary roller 13, and a chain is sleeved on the transmission sprocket 16. A reduction motor 14 is connected to one of the active rollers 12. The active roller 12 and the auxiliary roller 13 are rotatably connected to the support frame 11. The pressure frame 38 is located on the upper side of the two auxiliary rollers 13. The reduction motor 14 drives one of the active rollers 12 to rotate, which cooperates with the corresponding auxiliary roller 13 to make the conveyor belt 15 rotate. At the same time, the power is transmitted through the transmission sprocket 16 at the end of the auxiliary roller 13, so that the conveyor belt 15 on the other side rotates synchronously, which facilitates the conveying of the cardboard and allows the cardboard to be slit under the slitting mechanism.

[0026] In this embodiment: the guide assembly is arranged opposite to each other on the support frame 11 of the feeding end conveying assembly. The guide assembly includes an electric telescopic rod 21. The electric telescopic rod 21 is provided in two places. The end of the electric telescopic rod 21 is fixed to the guide plate 22 on the conveying assembly. The electric telescopic rod 21 extends and retracts to push the guide plate 22 to move, so that the cardboard moving on the conveyor belt 15 is aligned and transferred by the guide plate 22.

[0027] In this embodiment: the slitting mechanism includes a beam frame 31 mounted on a support frame 11. A cylinder 32 and a guide post 33 are fixed to the upper end of the beam frame 31. A mounting plate 34 is fixed to the lower end of the cylinder 32 and the guide post 33. An upper cutter 35 is mounted on the lower end of the mounting plate 34. An elastic holding component is mounted on the mounting plate 34 outside the upper cutter 35. A support plate 39 is mounted on the support frame 11 below the upper cutter 35. A lower cutter 310 is mounted on the upper end of the support plate 39. The elastic holding component includes guide rods 36 vertically spaced on the mounting plate 34. A pressure frame 38 is fixed to the lower end of the guide rods 36. A pressure frame 38 is fixed to the upper end of the guide rods 36. A spring 37 is fitted on the upper side; the guide post 33 is slidably connected to the beam frame 31, and the guide rod 36 is slidably connected to the mounting plate 34; the highest point of the lower cutter 310 is flush with the upper cutting surface of the conveyor belt 15. After the cardboard moves to the slitting position, the cylinder 32 extends and pushes the mounting plate 34 to move downward under the limit of the guide post 33, so that the pressure frame 38 contacts the cardboard first. As the mounting plate 34 continues to move downward, the guide rod 36 moves upward, and the pressure frame 38 squeezes the spring 37 on the outside of the guide rod 36. At the same time, the pressure frame 38 presses the cardboard until the upper cutter 35 contacts the cardboard, and the lower cutter 310 forms a slitting action on the cardboard.

[0028] The working principle and usage process of this utility model are as follows: A reduction motor 14 drives one of the active rollers 12 to rotate, which, in conjunction with the corresponding auxiliary roller 13, causes the conveyor belt 15 to rotate. Simultaneously, power is transmitted through the transmission sprocket 16 at the end of the auxiliary roller 13, causing the other conveyor belt 15 to rotate synchronously. An electric telescopic rod 21 extends, pushing the guide plates 22 to move, ensuring the spacing between the guide plates 22 meets the width requirements for the cardboard. The cardboard is placed on the conveyor belt 15 at the feeding end. As the cardboard moves towards the slitting mechanism on the conveyor belt 15, the guide plates 22 align and guide the cardboard. Once the cardboard has passed through the slitting mechanism and moved to the slitting position, the reduction motor 14 stops working. The cylinder 32 extends and pushes the mounting plate 34 downward under the limit of the guide post 33, so that the pressure frame 38 first contacts the cardboard. As the mounting plate 34 continues to move downward, the guide rod 36 moves upward, and the pressure frame 38 squeezes the spring 37 on the outside of the guide rod 36. At the same time, the pressure frame 38 presses the cardboard until the upper cutter 35 contacts the cardboard and forms a slitting action with the lower cutter 310. This ensures that the pressure frame 38 presses and fixes both sides of the slitting cardboard during the slitting process, improving the quality of cardboard slitting.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
