Description

Technical Field

[0001] This invention relates to the field of corrugated paper production technology, specifically to a corrugated paper production apparatus. Background Technology

[0002] In the production and processing of corrugated cardboard, die-cutting or slitting is a crucial step in forming sheets of a specific shape. Traditional cutting equipment typically places the corrugated cardboard on a fixed workbench, with the cutting head cutting from top to bottom. However, this process has the following technical drawbacks: First, waste materials such as paper scraps and dust generated during cutting easily accumulate in the cutting area. If not removed promptly, this can affect the positioning and flatness of the next sheet of cardboard and even scratch the product surface. Second, for corrugated cardboard with dense holes or complex contours, waste materials after cutting can easily get stuck inside the cardboard or fall onto the workbench, requiring manual cleaning, which is inefficient. Third, traditional workbenches are mostly solid flat panels, which cannot effectively utilize airflow to assist in positioning and collecting waste materials, resulting in a dusty working environment that harms the health of operators. Therefore, there is an urgent need in this field for an integrated corrugated cardboard production device that can automatically remove cutting waste and assist in cardboard positioning and collection. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a corrugated paper production apparatus that solves the aforementioned problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a corrugated paper production apparatus, comprising a base, a cutting head for cutting corrugated paper is provided on the top of the base, a slot is provided in the inner cavity of the base below the cutting head, a lower receiving plate is rotatably connected to the inner cavity of the slot, a negative pressure groove is provided in the inner cavity of the lower receiving plate, a filter plate is fixedly connected to the top of the lower receiving plate above the negative pressure groove, a positioning plate is fixedly connected to the bottom of the lower receiving plate, a pneumatic cylinder is fixedly connected to the surface of the positioning plate through a flexible metal tube connected to a vacuum pump, the inner cavity of the pneumatic cylinder is connected to the inner cavity of the negative pressure groove through multiple connecting pipes, a lifting cylinder is fixedly connected to the bottom of the base, a top head is fixedly connected to the top of the piston rod of the lifting cylinder, extending through and into the inner cavity of the slot, a groove adapted to the top head is provided at the bottom of the lower receiving plate, a blower head connected to a fan is fixedly connected to the left side of the slot, and a collection box is fixedly connected to the bottom of the base at the lower right of the slot.

[0005] As a further aspect of the present invention: the airflow direction of the blower head is parallel to the angle of the lower support plate after it has descended to its lowest position.

[0006] As a further aspect of the present invention: the inner cavity of the base is provided with a guide groove that communicates with the empty slot, so that the cut residue can be blown down for collection.

[0007] As a further aspect of the present invention: a pull-out plate is slidably connected to the bottom of the collection box, and the accumulated residue inside can be cleaned by pulling out the pull-out plate.

[0008] As a further aspect of the present invention: the side of the lower support plate is fixedly connected to an elastic membrane that is connected to the inner cavity of the slot.

[0009] As a further aspect of the present invention: the lower receiving plate and the elastic membrane form a semi-enclosed space with an opening on the right side inside the cavity of the empty slot, and the opening on the right side is located above the collection box.

[0010] Compared with the prior art, the present invention has the following advantages: The system achieves automatic dumping and pneumatic conveying collection of cutting waste: A rotatable lower receiving plate is installed, with a lifting cylinder and a lifting head positioned below it. During cutting operations, the lower receiving plate is placed horizontally; after cutting, the lifting cylinder pushes the lower receiving plate to rotate around its axis, tilting it and dumping any remaining waste into the collection box below. Simultaneously, a blower head blows a directional airflow, carrying fine dust and residual debris into the collection box, achieving automated, dry collection of waste.

[0011] A negative pressure adsorption-assisted positioning system was constructed to improve cutting accuracy: a negative pressure groove is opened in the lower receiving plate, and a filter plate is covered on top. The filter plate is connected to a pressure cylinder through a connecting pipe, and the pressure cylinder is connected to a vacuum pump through a flexible metal tube. When the corrugated cardboard is placed on the filter plate, the vacuum pump is activated, and a negative pressure is formed in the negative pressure groove, firmly adsorbing the cardboard onto the surface of the lower receiving plate. This effectively prevents the cardboard from shifting or warping during the cutting process, significantly improving cutting accuracy.

[0012] The waste guiding and collection structure has been optimized for ease of maintenance: a guide slot on the left side of the empty trough allows the airflow from the blower to smoothly guide the waste into the collection box. A pull-out plate at the bottom of the collection box allows for periodic removal to clean accumulated residue. The elastic membrane connected to the side of the lower receiving plate forms a semi-enclosed space with an opening on the right side of the empty trough cavity. This allows the lower receiving plate to rotate freely while preventing waste from scattering from the side, ensuring that all waste falls into the collection box.

[0013] Improved device operational stability and working environment cleanliness: The airflow direction of the blower head is parallel to the angle of the lower receiving plate after it descends to its lowest position, ensuring that the airflow can effectively sweep across the inclined surface of the receiving plate. The synergistic operation of negative pressure adsorption and automatic tilting greatly reduces the frequency of manual cleaning, reduces dust emissions, and improves the working environment.

[0017] Please see Figure 1-4 This invention provides a technical solution: a corrugated paper production device, including a base 1, a cutting head 3 for cutting corrugated paper is provided on the top of the base 1, a slot 4 is provided in the inner cavity of the base 1 below the cutting head 3, a lower receiving plate 2 is rotatably connected to the inner cavity of the slot 4, a negative pressure groove 6 is provided in the inner cavity of the lower receiving plate 2, a filter plate 7 is fixedly connected to the top of the lower receiving plate 2 above the negative pressure groove 6, a positioning plate is fixedly connected to the bottom of the lower receiving plate 2, and a filter plate is fixedly connected to the surface of the positioning plate. A pressure cylinder 9 is connected to a vacuum pump via a flexible gold wire hose. The inner cavity of the pressure cylinder 9 is connected to the inner cavity of the negative pressure tank 6 via multiple connecting pipes 8. A lifting cylinder 11 is fixedly connected to the bottom of the base 1. A top head 12 is fixedly connected to the top of the piston rod of the lifting cylinder 11, which penetrates and extends into the inner cavity of the empty tank 4. A groove 10 adapted to the top head 12 is opened at the bottom of the lower support plate 2. A blower head 5 connected to a fan is fixedly connected to the left side of the empty tank 4. A collection box 14 located at the lower right of the empty tank 4 is fixedly connected to the bottom of the base 1.

[0018] The airflow direction of the blower head 5 is parallel to the angle of the lower support plate 2 after it has descended to its lowest position.

[0019] The inner cavity of the base 1 is provided with a guide groove 13 that communicates with the empty groove 4. The guide groove 13 facilitates the blowing of the cut residue into the lower part for collection.

[0020] A pull-out plate 15 is slidably connected to the bottom of the collection box 14. The residue accumulated inside can be cleaned by pulling out the pull-out plate 15.

[0021] An elastic membrane is fixedly connected to the side of the lower support plate 2 and is connected to the inner cavity of the slot 4.

[0022] The lower receiving plate 2 and the elastic membrane form a semi-enclosed space with an opening on the right side inside the cavity of the empty slot 4, and the opening on the right side is located above the collection box 14.

[0023] In use, the first stage of this invention involves feeding and negative pressure adsorption. The corrugated cardboard to be cut is placed on the filter plate 7 on top of the lower receiving plate 2. The vacuum pump connected to the air cylinder 9 is activated, generating negative pressure through the flexible hose and the air cylinder. This negative pressure is transmitted to the negative pressure groove 6 via multiple connecting pipes 8. Because the filter plate 7 has air vents, the negative pressure acts on the lower surface of the cardboard, firmly adhering it to the lower receiving plate. At this time, the lower receiving plate is horizontal and located directly below the cutting head 3.

[0024] Phase Two: Cutting Operation The cutting head 3 is activated to cut the corrugated cardboard. During the cutting process, some of the paper scraps, dust, and other waste materials fall onto the surface of the lower receiving plate and the filter plate. Due to the continuous negative pressure, fine dust is adsorbed on the surface of the filter plate or falls into the negative pressure tank through the filter holes, but it will not drift outside the equipment.

[0025] Phase 3: Waste dumping and pneumatic conveying After cutting, the vacuum pump is turned off to release the negative pressure adsorption. The lifting cylinder 11 is activated, its piston rod extends upwards, and the top head 12 enters the empty slot 4 and pushes into the groove 10 at the bottom of the lower receiving plate 2. As the lifting cylinder continues to extend, the lower receiving plate tilts upwards around its right-side pivot point, gradually raising its left side to form a slope tilting downwards to the right. The elastic membrane on the side of the lower receiving plate stretches accordingly, maintaining a seal with the inner wall of the empty slot. Simultaneously, the blower head 5, connected to the fan, is activated, blowing out a directional airflow. Since the lower receiving plate is tilted to its lowest position and parallel to the blower head's airflow direction, the airflow sweeps along the slope surface from left to right, blowing waste paper scraps, dust, etc., from the lower receiving plate into the opening on the right side of the empty slot 4, where they fall into the collection box 14 located below. Some of the airflow is also guided by the guide groove 13 to ensure thorough cleaning without any blind spots.

[0026] Phase 4: Resetting and Waste Cleanup After the tilting is complete, the piston rod of the lifting cylinder 11 retracts, and the lower receiving plate 2 returns to a horizontal position under the action of gravity or the auxiliary reset mechanism, causing the elastic membrane to contract. Waste accumulated in the collection box 14 can be periodically removed by pulling out the bottom pull-out plate 15 for centralized cleaning. This completes one work cycle, and the next sheet of cardboard can be placed in, repeating the above steps.

[0027] Phase 5: Filter plate self-cleaning optional If the surface of filter plate 7 becomes clogged due to long-term use, the vacuum pump can be turned on and reversed when there is no cardboard, or the airflow from the blower head can be used to blow back the dust adhering to the filter plate into the collection box.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
