[0001] This invention relates to the technical field of cardboard scrap collection and bundling devices, specifically to an automatic paper scrap cutting and collection device and its process for use in cardboard forming production lines. Background Technology

[0002] In the existing corrugated cardboard pressing and molding production line, after the corrugated cardboard is pressed, it needs to be cut into the specified specifications according to the actual use requirements. Therefore, it is necessary to cut the two sides of the cardboard after pressing to ensure the uniformity of the cardboard specifications and the flatness of the edges.

[0003] Currently, the industry generally uses manual collection to process waste paper scraps after cutting, but this method has many drawbacks: First, the cutting process generates a large amount of waste paper scraps, which are difficult to clean thoroughly by hand, not only polluting the production environment but also wasting waste paper scraps. Second, the manual collection and packaging process is cumbersome, requires a lot of manpower, and has low collection efficiency, which cannot match the continuous operation rhythm of the production line. Third, manually packaged waste paper scraps are loose, bulky, and low in density, which is not conducive to subsequent storage, transportation, and recycling. This results in a low recycling rate for waste paper scraps, which does not meet the industry's development needs for energy conservation, emission reduction, and green production.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example

[0019] Please see Figure 1-7 This embodiment discloses an automatic paper edge cutting and collecting device for a cardboard forming production line, including a cutting assembly. The cutting assembly is installed in the cardboard forming production line, which is an existing corrugated cardboard forming production line. It is used to form, bond, press, and laminate corrugated paper raw materials through the cardboard forming production line to realize the forming process of corrugated cardboard. In the cutting process, the formed cardboard needs to be cut, which will generate waste.

[0020] In the corresponding cutting assembly of the cardboard forming production line, a matching edge material collection assembly is set up. The cutting assembly is located at the exit of the cardboard forming production line and is used to cut the sides of the formed cardboard. The cutting assembly includes at least two cutting units 200, which are located on both sides to determine the width of the cardboard. Depending on different cutting processes, multiple cutting units 200 can be used for cutting. It also includes a frame 100, which is located on the cardboard forming production line. The cutting units 200 are installed on the frame 100. The frame 100 includes a frame body, a guide rod 120 and a travel screw 110. The cutting units 200 can be moved and adjusted along the travel screw 110 to achieve the corresponding setting of cutting size specifications.

[0021] In its specific structure, the cutting unit 200 includes a cutting wheel 260, a cutting drive motor 240 for driving the cutting wheel 260, a cutting adjustment part for adjusting the height of the cutting wheel 260, and a cutting base for moving the cutting unit 200. The cutting base includes a sliding seat 210 and a guide seat 230. The sliding seat 210 cooperates with the stroke screw 110, and the guide seat 230 cooperates with the guide rod 120. The cutting adjustment part includes a lifting cylinder 220 and an adjusting slide rail seat 250. The lifting cylinder 220 is mounted on the sliding seat 210, and the adjusting slide rail seat 250 is mounted on the guide seat 230. The cutting drive motor 240 is mounted on the adjusting slide rail seat 250. The optimized design of the cutting unit 200 facilitates corresponding adjustments with the frame 100, enabling the cutting of cardboard.

[0022] The edge material collection assembly, located on both sides of the paperboard forming production line outlet, is designed to work in conjunction with the corresponding cutting unit 200 in the cutting assembly. The edge material collection assembly includes an inlet end 300, a feeding pipe 400, a centrifugal fan 500, and a conveying main pipe 600. The centrifugal fan 500 maintains the inlet end 300 under negative pressure. When waste material from the side cutting of the paperboard is sucked in through the inlet end 300, it is conveyed through the feeding pipe 400 to the centrifugal fan 500, and then transported along the conveying main pipe 600 to the collection assembly. The edge material collection assembly is optimized to utilize the centrifugal fan 500 to create negative pressure at the inlet end 300. This allows the waste material to be directly fed into the feed end 300 after the cardboard is cut by the cutting unit 200, under the influence of negative pressure, thus achieving automated collection of waste material. In the specific structure, the feed end 300 is equipped with a guide feed section 310 and a connecting section 320. One end of the feeding pipe 400 is connected to the connecting section 320. The guide feed section 310 is used to fit and cooperate with the conveyor table of the cardboard forming production line. The guide feed section 310 adopts an inclined arc plate to facilitate the introduction of waste material into the connecting section 320, thereby avoiding blockage of the feed end 300. In addition, the feed end 300 adopts a design with a large inlet and a small outlet to improve the collection effect.

[0023] The optimized design utilizes a centrifugal fan 500 for transfer, which can be matched with multiple different cutting units 200 to collect waste materials. This facilitates the simultaneous installation of multiple feeding pipes 400, thereby increasing the collection effect and reducing the overall pipe travel. Furthermore, after using the centrifugal fan 500 for transfer, the main conveying pipe 600 can be a fixed pipeline, allowing for a more rational arrangement of the feeding pipes 400. This also further enhances the negative pressure adsorption effect at the feed end 300, preventing the adsorption effect from being affected by excessively long paths. The combination of the main conveying pipe 600 and multiple feeding pipes 400 improves the overall layout rationality and facilitates future expansion.

[0024] The material collection assembly 700 includes a centrifugal cylinder 710, a collection box 720, a pressing box 730, and an extrusion drive assembly. A conveying manifold 600 is installed in conjunction with the centrifugal cylinder 710 to transfer waste material into the centrifugal cylinder 710. The centrifugal cylinder 710 is a commonly used centrifugal tank in the prior art, used to achieve centrifugal separation, separating the waste material collected in the conveying manifold 600 to prevent dust and other impurities from mixing into the waste material to be packaged. The separated waste material is then sent into the collection box 720. The collection box 720 is located at the lower part of the centrifugal cylinder 710. 0. A reamer mechanism is installed inside the collection box 720. The reamer mechanism is used to cut the waste material. The reamer mechanism includes two reamer units 721. The two reamer units 721 adopt a double-axis staggered structure. The reamer unit 721 includes a reamer shaft 723 and several reamer bodies 722 arranged on the reamer shaft 723. The double-axis staggered arrangement structure design can crush the waste material, avoid some waste material being too long and affecting the extrusion process, improve the uniformity of waste material packaging, and the double-axis staggered arrangement structure of the reamer unit 721 can increase the cutting processing of waste material.

[0025] In conjunction with the above, the lower part of the collecting box 720 is the pressing box 730, and an extrusion drive assembly is fitted on one side of the pressing box 730. The extrusion drive assembly includes a hydraulic cylinder 740 and a paper pressing carriage 750. The hydraulic cylinder 740 is used to drive the paper pressing carriage 750 to move along the inner cavity of the pressing box 730. The pressing box 730 is also equipped with a material blocking gate 760 and a discharge section 770. The discharge section is located outside the material blocking gate 760. The material blocking gate 760 is used to cooperate with the paper pressing carriage 750 to realize the extrusion molding of the waste material in the inner cavity of the pressing box 730. In the specific operation process, the pressing box 730 usually performs multiple reciprocating extrusion processes, and the collecting box 720 intermittently conveys the waste material into the pressing box 730 until the paper pressing carriage 750 in the pressing box 730 completes the molding of the waste material to the specified specifications.

[0026] In its specific structure, the paper pressing carriage 750 includes a carriage body 751, a wheel assembly located on the side of the carriage body 751, and an extrusion surface 753 located on the end face of the carriage body. The wheel assembly includes a bottom wheel assembly 757 and a side wheel assembly 756. The extrusion surface 753 includes a first extrusion surface 754 and a second extrusion surface 755, with the second extrusion surface 755 being inclined. The overall structure of the paper pressing carriage 750 is optimized, and the arrangement of the extrusion surfaces 753 is optimized. The first extrusion surface 754 and the second extrusion surface 755 are used in combination to improve the extrusion molding effect.

[0027] In conjunction with the above, it also includes a dust collection assembly, which includes a dust collection tower 780 and a dust suction pipe 711. One end of the dust suction pipe 711 is used to be installed in conjunction with one side of the centrifugal cylinder 710, and the other end is used to be installed in conjunction with the dust collection tower 780. The dust collection tower 780 includes a dust inlet chamber 783, several flexible bags 781, and a dust discharge section 782. The dust suction pipe 711 is used to communicate with the dust inlet chamber 783, the upper end of the flexible bags 781 is used to communicate with the dust inlet chamber 783, and the lower end of the flexible bags 781 is used to communicate with the dust discharge section 782. The optimized structural design of the flexible bags 781 facilitates dust collection and avoids the problem of dust accumulation on the inner wall of the traditional dust collection tower 780, which makes internal cleaning difficult.

[0028] In summary, this embodiment optimizes the design of the edge material collection assembly, which corresponds one-to-one with the cardboard cutting unit. It is used to collect waste paper edges and scraps generated during cutting in real time. The structure design of the feeding end is optimized to facilitate the rapid collection of waste paper edges generated during cutting. The negative pressure provided by the centrifugal fan enables rapid adsorption of waste paper edges and scraps. At the same time, it can integrate the waste paper edges from multiple stations on the entire cutting line for centralized collection. By discharging them into the main conveying pipe, the waste paper edges are centrally conveyed, achieving automated collection of waste paper edges.

[0029] This embodiment can realize automated collection of waste materials, integrating them into a collection assembly. The collection assembly can be used to package the waste materials, realize the automated collection, crushing, compression and bundling of waste paper scraps, reduce manpower input, improve collection efficiency and recycling rate, reduce pollution in the production environment, adapt to the transformation needs of existing production lines, and achieve energy saving and consumption reduction. Example

[0030] Based on Embodiment 1, this embodiment discloses an automatic paper edge cutting and collection process for a cardboard forming production line, employing an automatic paper edge cutting and collection device for a cardboard forming production line as described in the embodiment. The specific steps are as follows: S1. Corrugated board forming: The corrugated board raw material is fed into the board forming production line to complete the crimping, lamination and forming process of the corrugated board to obtain the formed corrugated board; S2. Side cutting process: The formed corrugated cardboard is transferred to the cutting assembly, and side cutting is carried out along the corrugated cardboard conveying direction. The two sides of the formed corrugated cardboard are cut simultaneously to obtain the finished corrugated cardboard that meets the specifications and the waste material on both sides. The cutting unit adjusts the cutting speed, cutting side distance, etc. according to the specifications of the corrugated cardboard and the process requirements. S3. Waste negative pressure collection: Keep the centrifugal fan running to create a negative pressure environment at the feed end. The cut waste is drawn into the feed end by the negative pressure adsorption and then transferred to the centrifugal fan through the feeding pipe. The centrifugal fan then transfers the collected waste to the collection assembly through the conveying main pipe. The negative pressure of the centrifugal fan is controlled at 0.06-0.08MPa. Under the negative pressure of the centrifugal exhaust fan, the waste and waste paper scraps are conveyed through the feeding pipe at a speed of 1.2-1.5m / s, and then transferred to the conveying main pipe by the centrifugal exhaust fan, and finally conveyed into the centrifugal drum. S4. Centrifugal Separation and Dust Collection: The main conveyor pipe transports the waste material to the centrifugal cylinder in the collection assembly. The centrifugal cylinder centrifuges the waste material to separate the waste material from the dust mixed in. The separated waste material falls into the collection box, while the dust is sucked into the dust collection tower through the dust suction pipe of the dust collection assembly. S5. Edge and scrap material processing: Activate the reamer mechanism inside the collection box to process the waste material falling into the collection box into scrap; the speed difference between the two reamer units is 100-200 r / min, and the blade spacing between the two reamer units is 2-3 mm; the collection box is located below the centrifugal cylinder and is connected to the centrifugal cylinder. The collection box is equipped with a reamer mechanism, which is driven by a drive motor. The rotating reamer can cut the waste paper edge material entering the collection box into scrap, improve the uniformity of the waste material, and facilitate subsequent extrusion molding; S6. Extrusion Molding: Close the baffle gate in the collection box, and the crushed waste material is conveyed to the pressing chamber of the pressing box. Start the hydraulic cylinder and drive the paper pressing cart to compress the waste material in the pressing chamber. Repeatedly compress until a waste pile of the process specifications is formed. The pressing chamber is equipped with a paper pressing cart, which is hydraulically driven and can move radially along the inner wall of the extrusion chamber. Through the reciprocating compression of the paper pressing cart, the waste paper fragments in the extrusion chamber are compacted. And through the segmented feeding of the collection box, it is finally formed into a high-density, small-volume bundled square bag, which is convenient for later storage, transportation and recycling. S7. Bundling and Packaging for Recycling: Bundling the waste pile.

[0031] Combining the above processes, waste collection can be automated, reducing manpower input: through the coordinated work of negative pressure collection, centrifugal exhaust fan integrated transfer, centrifugal separation, and extrusion packaging, the entire process of waste collection, crushing, extrusion and bundling is automated, which greatly reduces labor costs and improves collection efficiency and recycling rate; negative pressure adsorption and sealed conveying can effectively prevent waste paper leakage, avoid waste paper pollution of the production environment, and at the same time reduce dust and improve the working environment.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
