Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of box processing, and in particular relates to a carton creasing device. Background Art
[0002] Cartons are the most widely used packaging products. Depending on the material used, they come in various sizes and models, including corrugated and single-layer cardboard boxes. Three-layer and five-layer cartons are commonly used, with seven-layer cartons being less common. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. Lining and face paper can be made from tea board or kraft paper, while the core paper is corrugated paper. Corrugated boxes are the most widely used and consistently the most consumed packaging product. Corrugated boxes are rigid paper containers made from corrugated cardboard through die-cutting, creasing, and stapling or gluing. For over half a century, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers due to their superior performance and good processing properties, becoming the mainstay of transport packaging. During the corrugated box forming process, the folded portion must be creasing before the box can be successfully manufactured. Therefore, a linear creasing device with a reciprocating creasing element is crucial. Utility Model Content

[0004] A second slide rail is fixed on the second column, a second slider is arranged on the second slide rail, the second movable column passes through the output port, and a pressing piece is fixed between the second movable column and the second slider.
[0005] Through the above technical solution, when the turntable rotates, the driving column also rotates, and due to the setting of the track, the moving part can move up and down, thereby controlling the up and down movement of the pressing part, and the slider follows the movement. The workbench is provided with a groove, and the groove is located below the orthographic projection of the pressing part.
[0006] As a preferred embodiment of the above, the track includes a downwardly concave arc segment and a transversely extending segment connected on both sides of the arc segment.
[0007] Through the above technical solution, the arc segment drives the partial ring of the circle where the column is located. Therefore, when in the arc segment, the end of the pressing piece is located in the groove, which can increase the pressing time and enhance the indentation forming effect.
[0008] As a preferred embodiment of the above, a limiting plate is further included. The workbench is provided with a recessed area, and a plurality of threaded holes are provided in the recessed area. The limiting plate is installed in the recessed area through the threaded holes.
[0009] With the above technical solution, the cardboard will hit the surface of the limiting plate. If the threaded hole is directly opened on the workbench, there will be a gap between the bottom of the limiting plate and the workbench, affecting the positioning of the cardboard.
[0010] The limiting plate can be detachably fixed via threaded holes, making it suitable for indentation positioning of various cartons.
[0011] As a preferred embodiment of the above, it further includes a driving motor, wherein the output shaft of the driving motor is fixedly connected to the turntable, and the driving motor is fixed on the workbench or the outer wall of the first column.
[0012] As a preferred embodiment of the above, a gap is formed between the inner wall of the groove and the outer wall of the pressing piece.
[0013] With the above technical solution, since the carton has a thickness that cannot be ignored, the gap provides space for the carton to bend and avoid breaking.
[0014] As a preferred embodiment of the above, a plurality of notches are provided at the bottom of the pressing piece.
[0015] Through the above technical solution, the setting of the notch can realize the setting of the dotted line indentation.
[0016] Compared with the existing technology, the advantages of the present invention are: the present invention has a simple structure, and compared with the traditional cylinder pressing, the present invention uses a turntable to control the up and down drive of the moving part to control the pressing of the pressing part, and the pressing time is increased to achieve a stable pressing function.
