Description

Technical Field

[0001] This utility model relates to the field of cardboard slotting equipment, and in particular to a cutting blade angle adjustment device for a cardboard slotting machine. Background Technology

[0002] Cardboard slotting machines can cut slots of a certain width and depth into cardboard according to pre-set dimensions and positions. The cross-section of these slots is generally V-shaped. These slots are crucial for the forming of cardboard products such as boxes and cartons. For example, when making cartons, the long slots cut into the cardboard by the slotting machine allow the cardboard to be folded along the slots to form the box shape. However, the cutting units on existing equipment usually cannot be independently fine-tuned; the angle of the cutter can only be adjusted by rotating the blade holder, which houses several cutting units. This cannot meet the production needs of more varied and larger blank boxes. Utility Model Content

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. A cutting blade angle adjustment device for a cardboard slotting machine includes a cutting blade unit 1. The cutting blade unit 1 includes a mounting rod 11, a swing mounting head 12, a cutting blade 13, and an adjustment assembly. The cutting blade 13 is fixedly disposed at the end of the swing mounting head 12, and the orientation of the cutting blade 13 corresponds to the cardboard conveying path. A transmission gear 121 is fixedly disposed on the swing mounting head 12. The transmission gear 121 can be fixedly embedded in the swing mounting head 12, or welded to the swing mounting head 12, etc. The method of fixing the transmission gear 121 is described by those skilled in the art. The mounting rod 11 is rotatably mounted with a drive gear 111, which meshes with a transmission gear 121. The adjustment assembly includes an adjustment shaft 2, which is aligned with the axis of the drive gear 111. The adjustment shaft 2 is fixedly connected to the drive gear 111 and passes through the side of the mounting rod 11. The adjustment shaft 2 has an extension 21 extending to the outside of the mounting rod 11, which is used to connect to a rotational power source, which can be manually rotated or automatically rotated by a motor. A fastening bolt 3 coaxially passes through the transmission gear 121, and the transmission gear 121 is sleeved on the fastening bolt 3. The mounting rod 11 and the swing mounting head 12 are connected by the fastening bolt 3. The swing mounting head 12 has a screw hole that matches the fastening bolt 3. The fastening bolt 3 passes through the mounting rod 11, the transmission gear 121, and the swing mounting head 12 in sequence to fasten the mounting rod 11 and the swing mounting head 12.

[0020] Slightly unscrew the fastening bolt 3 to loosen the oscillating mounting head 12, thus releasing the fastening of the mounting rod 11 and the oscillating mounting head 12 and facilitating the rotation of the transmission gear 121. When the adjusting shaft 2 rotates, the drive gear 111 drives the transmission gear 121, causing the oscillating mounting head 12 to oscillate around the axis of the fastening bolt 3 to adjust the angle of the cutter 13. After the angle of the oscillating mounting head 12 is adjusted, the fastening bolt 3 tightens the mounting rod 11 and the oscillating mounting head 12.

[0021] When the rotational power source is manual, the extension 21 is equipped with a non-slip handle, a knob, or a groove 22 that matches the screwdriver. The screwdriver refers to a wrench or similar device that rotates the adjusting shaft 21 by engaging with the shape of the groove to adjust the angle of the cutting head.

[0022] The mounting rod 11 is provided with a guide arc groove 4, and the swing mounting head 12 is provided with a fastening hole 6 corresponding to the guide arc groove 4. The guide arc groove 4 and the fastening hole 6 are connected by a guide bolt 5. The guide bolt 5 can further tighten the swing mounting head 12 and the mounting rod 11 to ensure the stability of the cutting unit 1 in the working state. In addition, when it is necessary to adjust the angle of the cutter 13, the guide bolt 5 and the fastening bolt 3 can be loosened at the same time. The guide bolt 5 can be completely removed or partially left on the swing mounting head 12, so that the swing mounting head 12 moves along the trajectory of the guide arc groove 4 and moves stably.

[0023] The drive gear 111 and the transmission gear 121 can be respectively disposed on the outside of the mounting rod 11 and the swing mounting head 12. In order to further avoid the drive gear 111 and the transmission gear 121 from being contaminated by paper scraps and dust, a receiving cavity 7 is formed between the mounting rod 11 and the swing mounting head 12. The drive gear 111 and the transmission gear 121 are located in the receiving cavity 7, which extends their service life.

[0024] To facilitate adjustment, the swing mounting head 12 is provided with an angle scale mark, and the mounting rod 11 is provided with an indicator mark corresponding to the scale mark, so as to realize visual adjustment and facilitate adjustment.

[0025] The cutting unit 1 has at least two sets, and the cutting unit 1 is mounted on a movable plate 8. The movable plate 8 is mounted on the frame via a longitudinal rail 9. The longitudinal rail 9 is mounted on the frame, and the two sides of the movable plate 8 are connected to the longitudinal rail 9 respectively, moving in the front-back direction. Because the structure of the cardboard slotting machine is compact, it is inconvenient to manually adjust the cutter 13. Therefore, the movable plate 8 can be moved backward along the longitudinal rail 9 to facilitate the adjustment of the cutter 13. The movable plate 8 is connected to an assembly drive component that drives its front-back movement. The assembly drive component can be a servo motor, a cylinder, or an electric push rod, etc. The servo motor can drive the movable plate 8 to move back and forth via a lead screw mechanism.
