Description

Technical Field

[0001] This utility model relates to the field of cardboard processing technology, and in particular to an automatic cardboard creasing and slotting machine. Background Technology

[0002] Automatic cardboard creasing and slotting machine is a high-efficiency processing equipment designed specifically for cardboard products such as cartons and boxes. It performs precise creasing and slotting operations on cardboard, first forming clear creasing lines at the folding positions, and then using knives or molds to perform slotting, achieving a neat and durable folding structure. It can quickly and stably process cardboard of different thicknesses and specifications, significantly improving production efficiency, reducing labor costs, reducing material waste, and improving the appearance and strength of finished products.

[0003] However, traditional automatic cardboard creasing and grooving machines typically lack an effective adsorption and positioning auxiliary system on their worktables. After the cardboard is placed, it is easy for it to shift, requiring manual fine-tuning or repositioning, resulting in unstable initial orientation. This affects the centering and repeatability of subsequent processing. Furthermore, it cannot clean and adsorb debris, which easily accumulates on the worktable surface, affecting processing accuracy, heat dissipation, and subsequent adsorption and positioning effects. It may even contaminate the board surface or introduce foreign objects.

[0004] Therefore, those skilled in the art have provided an automatic cardboard creasing and slotting machine to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic cardboard creasing and slotting machine. This machine features a suction mechanism and a positioning mechanism on its worktable. Driven by a ventilation fan, the suction mechanism sequentially generates airflow within the ventilation shell, suction slot, and trapezoidal slot. This airflow, through ventilation holes on the placement plate, assists in the suction and positioning of the cardboard placed on the worktable. This allows for initial orientation of the cardboard at the initial placement stage, reducing the possibility of accidental displacement. Furthermore, driven by two servo motors, the positioning mechanism controls the horizontal and vertical levers to adjust the position of the cardboard, ensuring it is centered on the worktable. This reduces displacement or vibration during high-speed processing stages such as creasing and slotting, improving processing consistency and repeatability.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic cardboard creasing and slotting machine includes a worktable with a suction mechanism inside. The suction mechanism includes a placement slot and a ventilation shell. The upper end of the inner wall of the placement slot has an installation slot, and a placement plate is fitted into the inner wall of the installation slot. The upper surface of the placement plate has multiple ventilation holes. The lower end of the inner wall of the placement slot has a trapezoidal slot, and a suction slot is formed at the center of the bottom surface of the trapezoidal slot. A trapezoidal collection box is fitted into the inner wall of the trapezoidal slot, and a placement frame is fixedly connected to the center of the bottom surface of the trapezoidal collection box. A first metal filter screen is fixedly connected to the middle of the outer walls of the placement frame. Ventilation fans are fixedly connected to both sides of the middle of the inner wall of the ventilation shell.

[0008] The upper surface of the workbench is provided with a positioning mechanism, which includes a placement frame. A first servo motor is fixedly connected to the front end of one outer wall of the placement frame. A first bidirectional screw is fixedly connected to the output end of the first servo motor. A transverse lever is threadedly engaged on both sides of the outer wall of the first bidirectional screw. A transverse lever block is fixedly connected to the middle of the outer wall of the transverse lever. A second servo motor is fixedly connected to one side of the outer wall of the rear end of the placement frame. A second bidirectional screw is fixedly connected to the output end of the second servo motor. A longitudinal lever is threadedly engaged at both the front and rear ends of the outer wall of the second bidirectional screw.

[0009] Through the above technical solution, the suction mechanism set on the worktable of the automatic cardboard creasing and slotting machine can not only assist in positioning the cardboard on the placement board, but also absorb the debris generated during cardboard processing, thereby reducing the accumulation of debris on the worktable and minimizing the impact on processing accuracy.

[0010] Furthermore, the placement slot is located in the middle of the upper surface of the workbench, and a positioning frame is fixedly connected to the upper end of the outer wall of the trapezoidal collection box;

[0011] The above technical solution enables the trapezoidal collection box to be installed and fitted relatively stably in the placement slot through the positioning frame.

[0012] Furthermore, the ventilation shell is fixedly connected to the middle of the lower surface of the workbench, and a second metal filter screen is fixedly connected to both sides of the inner wall of the ventilation shell;

[0013] The above technical solution enables the second metal filter to protect the components inside the ventilation housing.

[0014] Furthermore, the placement frame is fixedly connected to the outer side of the upper surface of the workbench, and guide grooves are provided on both sides of the inner wall of the placement frame. A guide slide rod is fixedly connected to the middle of the inner wall of the guide groove.

[0015] The above technical solution enables the horizontal and vertical levers to slide smoothly on the guide slide.

[0016] Furthermore, a first guide slider is fixedly connected to the outer wall of the rear end of the transverse lever, and a first threaded block is fixedly connected to the outer wall of the front end of the transverse lever;

[0017] Through the above technical solution, the transverse lever can be smoothly translated and slid under the action of the first threaded block and the first guide slider.

[0018] Furthermore, a second threaded block is fixedly connected to the outer wall of one side of the longitudinal lever, and a second guide slider is fixedly connected to the outer wall of the other side of the longitudinal lever;

[0019] Through the above technical solution, the longitudinal lever can be moved and slid relatively smoothly under the action of the second threaded block and the second guide slider.

[0020] Furthermore, connecting grooves are provided on both sides of the outer wall of the front end of the longitudinal lever;

[0021] The above technical solution allows the longitudinal lever to slide in coordination with the transverse lever by setting a connecting groove.

[0022] Furthermore, an indentation and grooving module is fixedly connected to the upper end of the workbench, and a support frame is fixedly connected to the lower surface of the workbench.

[0023] The above technical solution enables the creasing and grooving module to process cardboard using different cutting rollers.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model proposes an automatic cardboard creasing and slotting machine. Compared with most traditional automatic cardboard creasing and slotting machines, this automatic cardboard creasing and slotting machine is equipped with a suction mechanism and a positioning mechanism on the worktable. Driven by a ventilation fan, the suction mechanism generates suction airflow in the ventilation shell, suction slot and trapezoidal slot in sequence. This airflow is used to assist in the suction and positioning of the cardboard placed on the worktable through the ventilation holes on the placement plate. This allows for initial orientation of the cardboard at the initial placement stage, reducing the possibility of accidental displacement. The positioning mechanism, driven by two servo motors, controls the horizontal and vertical levers to adjust the position of the cardboard so that it is centered on the worktable. This reduces displacement or vibration during high-speed processing stages such as creasing and slotting, improving the consistency and repeatability of processing.

[0026] 2. The automatic cardboard creasing and slotting machine proposed in this utility model, compared with most traditional automatic cardboard creasing and slotting machines, has a suction mechanism set on the worktable. This mechanism can not only assist in positioning the cardboard on the placement board, but also absorb the debris generated during cardboard processing, thereby reducing the accumulation of debris on the worktable and minimizing the impact on processing accuracy.

Place the cardboard to be processed on the placement plate 203. The ventilation fans 2012 sequentially generate airflow in the ventilation shell 2011, suction trough 206, and trapezoidal groove 205, thereby generating suction force within the ventilation holes 204 on the placement plate 203. This provides initial auxiliary positioning by creating a certain suction force on the placed cardboard. Subsequently... The first and second servo motors 3010 are started, and the horizontal lever 306 and the vertical lever 3012 are controlled to adjust the cardboard in coordination with the bidirectional screw and the threaded block. The cardboard is adjusted to be centered on the placement plate 203 according to the processing requirements, so that the creasing and grooving module 4 can process the cardboard. The airflow generated in the ventilation hole 204 can suck up the debris generated during processing. The debris is intercepted by the stainless steel first metal filter 2010 and collected in the trapezoidal collection box 207. The maintenance operation can be completed by disassembling the placement plate 203 and the trapezoidal collection box 207 for cleaning.
