Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cardboard processing, in particular to a corrugated cardboard sorting device. Background Art

[0002] Corrugated cardboard, also known as corrugated paperboard, is made by bonding at least one layer of corrugated paper and a layer of containerboard (also called linerboard). It exhibits excellent elasticity and extensibility. It is primarily used to manufacture cartons, cardboard inserts, and other packaging materials for fragile goods. It is primarily made from traditional straw pulp and waste paper, which is pulped to create a base similar to yellow cardboard. This is then mechanically processed and rolled into a corrugated shape. The surface is then bonded to the containerboard with adhesives such as sodium silicate. Although corrugated cardboard possesses high strength, the surface and edges are susceptible to damage during processing and transportation. This damaged corrugated cardboard poses a safety hazard when used to protect products. Therefore, a corrugated cardboard sorting device has been developed. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 , this embodiment provides a technical solution: a corrugated cardboard sorting device, including a frame 1, a receiving roller 6 and a material roller 7;

[0026] Frame 1: A feeding mechanism 2 for introducing corrugated cardboard 15 is fixed on the inner side of one end, and a loading belt 3 and a unloading belt 4 located below the loading belt 3 are provided on the inner side of the other end, and the overall height of the loading belt 3 is lower than the feeding mechanism 2;

[0027] It also includes a tidying mechanism 5 for intermittently blocking the corrugated cardboard 15, which is fixed to the frame 1 above the feeding mechanism 2; the tidying mechanism 5 can adjust the spacing position of the corrugated cardboard on the feeding mechanism 2 to facilitate the matching of the cardboard with the material hook;

[0028] The tidying mechanism 5 includes a top frame 501, a cylinder 502 and a baffle plate 503. The top frame 501 is fixed on the frame 1. The cylinder 502 is vertically fixed on the top frame 501. The baffle plate 503 is fixed on the cylinder arm of the cylinder 502.

[0029] The receiving roller 6 is rotatably arranged on the frame 1 between the feeding mechanism 2 and the loading belt 3, and the height of the receiving roller 6 is between the feeding mechanism 2 and the loading belt 3;

[0030] The horizontal part of the frame 1 is slidably provided with a slide 13, the lower end of the slide 13 is rotatably connected to the receiving roller 6, and a locking bolt 14 for squeezing the horizontal part of the frame 1 is provided in the threaded hole of the slide 13;

[0031] The material roller 7 is rotatably mounted on the frame 1 above the feeding belt 3. A material hook 9 supporting the end of the corrugated cardboard 15 is slidably mounted on the circumferential surface of the material roller 7. A drive motor 10 is fixed to the frame 1, and the output shaft of the drive motor 10 is fixedly connected to the end of the material roller 7.

[0032] A radial chute 701 is provided on the circumferential surface of the material roller 7, and the chute 701 is slidably engaged with the material hook 9. An airbag column 8 is installed in the inner cavity of the material roller 7, and the airbag column 8 is located between the material hooks 9. The end of the airbag column 8 has a rotary joint 12, and the rotary joint 12 passes through the through hole at the center of the end surface of the material roller 7;

[0033] The airbag column 8 drives the material hook 9 to slide radially in the material roller 7. When sliding out, it can catch the end of the corrugated cardboard 15, thereby guiding the corrugated cardboard 15 to the upper material belt 3 and the lower material belt 4 according to the quality of the corrugated cardboard 15, thereby realizing the sorting of the corrugated cardboard;

[0034] The external air source is connected to the airbag column 8 via a rotary joint 12;

[0035] The material hook 9 includes a sliding plate 901 in the chute 701. The outer end of the sliding plate 901 is fixed with an end plate 902. The inner end of the sliding plate 901 is fixed with a patch 903. The patch 903 is bonded to the side of the airbag column 8. The outer end of the sliding plate 901 is connected to the end plate 902 to form a hook shape, which is conducive to driving the movement of the corrugated cardboard.

[0036] Among them: it also includes an image sensor 11, which is installed at the position of the frame 1 corresponding to the corrugated cardboard 15. The corrugated cardboard is visually inspected based on the image sensor, and the corrugated cardboard with damaged surface or corners is removed.

[0037] The working principle of the corrugated cardboard sorting device provided by the utility model is as follows:

[0038] Feeding mechanism 2 along Figure 3 The corrugated cardboard 15 is conveyed horizontally to the right in the direction shown. During the conveying process, the cylinder 502 drives the baffle plate 503 to periodically descend. The baffle plate 503 is lowered close to the feeding mechanism 2 until the right end of the corrugated cardboard 15 abuts the baffle plate 503. When released, the baffle plate 503 is lifted. The corrugated cardboard 15 has a fixed release position, so it is conveyed to the right at equal intervals.

[0039] The corrugated cardboard 15 continues to move to the right, and the image sensor 11 recognizes it and feeds it back to the external controller to control the air supply to the airbag column 8. The corrugated cardboard 15 continues to move to the right end and leaves the feeding mechanism 2, then falls and is supported by the receiving roller 6.

[0040] If the corrugated cardboard 15 is not damaged, the hook 9 is in a retracted state. At this time, the corrugated cardboard 15 slides toward the lower right side. The right end is first supported by the unloading belt 4, and the left end gradually separates from the receiving roller 6, and is then sent to the next processing step by the unloading belt 4.

[0041] If the corrugated cardboard 15 is damaged, the controller controls the external air source to supply air to the airbag column 8 through the rotary joint 12. When the airbag column 8 expands and squeezes, the material hook 9 extends radially, so that the right end of the sliding corrugated cardboard 15 rests on the bending part of the sliding plate 901 and the end plate 902. Under the action of the drive motor 10 driving the material roller 7 counterclockwise, the right end of the corrugated cardboard 15 is guided to continue to move one end distance to the right and fall onto the upper feeding belt 3. The right end is first supported by the feeding belt 3, and the left end gradually separates from the receiving roller 6, and is then sent to the lower waste box by the feeding belt 3.

[0042] It is worth noting that the controller disclosed in the above embodiments can be a programmable controller of model S7-200, the feeding mechanism 2, the loading belt 3 and the unloading belt 3 can be belt conveyors, specifically Shenda's QG88, and the image sensor 11 can be Sony's XC-EI30CE industrial infrared camera.

[0043] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
