[0017] Example 1

[0018] like Figure 1 and Figure 2 As shown, the utility model proposes an adjustable cardboard slotting machine, including a conveying mechanism 1 and an adjusting mechanism; a slotting mechanism 101 is provided on the conveying mechanism 1; the adjusting mechanism is installed on the conveying mechanism 1 and is located on the input end side of the slotting mechanism 101, and the adjusting mechanism and the conveying mechanism 1 cooperate with each other to convey multiple groups of cardboards one by one to the slotting mechanism 101, and align the positions to be slotted on the cardboards with the slotting blades on the slotting mechanism 101.

[0019] The adjustment mechanism includes an adjustment frame, a first limit plate 3 and a second limit plate 403; the adjustment frame is installed at the top of the conveying mechanism 1; two groups of first limit plates 3 are provided, and the two groups of first limit plates 3 can be adjustably installed on the adjustment frame; the second limit plate 403 can be adjustably set at the discharge end between the two groups of first limit plates 3.

[0020] Furthermore, the adjustment frame is composed of a support base 2 installed at the top edge of the conveying mechanism 1 and a horizontal plate 201 installed on the inner wall of the support base 2. The support base 2 is set to be U-shaped, and multiple groups of first adjustment holes 202 are evenly opened on the horizontal plate 201. A scale corresponding to the first adjustment hole 202 is opened on the side wall of the horizontal plate 201.

[0021] Furthermore, the top of the first limiting plate 3 is connected to a connecting seat 303, which is set to be L-shaped. The connecting seat 303 is slidingly connected to the horizontal plate 201. The top of the first limiting plate 3 is slidingly connected to the bottom of the horizontal plate 201. The connecting seat 303 is limited by bolts and the horizontal plate 201, and the bolts are threadedly connected to the first adjustment hole 202.

[0022] Furthermore, a bracket 301 is installed at the bottom end of the first limiting plate 3, and a first roller 302 is provided on the bracket 301. The first roller 302 is rollingly connected to the conveyor belt on the conveying mechanism 1, which is convenient for stably supporting the first limiting plate 3 and preventing the first limiting plate 3 from interfering with the operation of the conveyor belt on the conveying mechanism 1. At the same time, it is convenient to limit the cardboard located at the bottom layer between the two groups of first limiting plates 3, so that the cardboard can only move toward the slotting mechanism 101 driven by the conveyor belt on the conveying mechanism 1 to avoid derailment, thereby improving the slotting efficiency.

[0023] Furthermore, a limiting seat 4 is provided at the discharge end of the two groups of first limiting plates 3, a slide 402 is provided on the side wall of the limiting seat 4, the second limiting plate 403 is slidably connected between the two groups of slides 402, and multiple groups of second adjustment holes 401 are evenly provided on the limiting seat 4, and the second limiting plate 403 and the second adjustment hole 401 are limited by bolts.

[0024] In this embodiment, the two groups of first limiting plates 3 are slid and adjusted on the transverse plate 201 so that multiple groups of stacked cardboards can be limited between the two groups of first limiting plates 3. At the same time, the two groups of connecting seats 303 are slid along the transverse plate 201 so that the position to be slotted on the cardboard corresponds to the slotting knife on the slotting mechanism 101. When the connecting seat 303 drives the first limiting plate 3 to slide to a suitable position, the connecting seat 303 is fixedly connected to the corresponding first adjustment hole 202 by bolts, and the first limiting plate 3 can be fixed to the transverse plate 201. At this time, multiple groups of cardboards are stacked and placed on the conveyor belt in the conveying mechanism 1 between the two groups of first limiting plates 3. Then, the second limiting plate 403 is slid upward or downward along the slide 402 to The height is suitable so that the distance between the bottom end of the second limiting plate 403 and the conveyor belt in the conveying mechanism 1 is adapted to the thickness of the cardboard. The second limiting plate 403 is fixedly connected to the adapted second adjustment hole 401 by a bolt, and the conveying mechanism 1 is started to drive the cardboard between the two groups of first limiting plates 3 to move, and the cardboard at the bottom layer is conveyed toward the slotting mechanism 101. When the cardboard at the bottom layer separates from the two groups of first limiting plates 3, the cardboard above it falls to the conveying mechanism 1 under the action of gravity and continues to be conveyed, thereby realizing automatic loading. When the cardboard is transported to the slotting mechanism 101 by the conveyor belt on the conveying mechanism 1, the cardboard is slotted by the slotting mechanism 101. The adjustment is convenient and quick, thereby improving the slotting efficiency.

[0025] Example 2

[0027] In this embodiment, the connecting rod 5 is connected to the first limit plate 3 by bolts. When the position of the first limit plate 3 on the horizontal plate 201 is adjusted, the corresponding connecting rod 5 can be driven to adjust. After the two groups of first limit plates 3 are adjusted to their positions, the cardboard is conveyed to the bottom of the slotting mechanism 101 by the conveying mechanism 1, and the electric push rod 502 is started to drive the U-shaped seat 503 to move downward until the pressing roller 504 contacts the cardboard. The pressing roller 504 is connected to the cardboard in a rolling manner, and the cardboard is slotted by the slotting mechanism 101 at the same time. The setting of the pressing roller 504 can press the cardboard to avoid deviation during the slotting process, which facilitates the slotting of the slotting knife in the slotting mechanism 101 and does not interfere with the conveyance of the cardboard.
