[0001] This utility model relates to the field of cardboard box production technology, and more specifically, to a cardboard box creasing device for cardboard box production. Background Technology

[0002] Cardboard boxes are widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. They are a relatively environmentally friendly packaging material. In the process of processing cardboard boxes, the raw cardboard needs to be creasing. Therefore, a cardboard creasing device is needed to creasing the raw cardboard, so that folding creases are created on the raw cardboard, making it easier to fold the cardboard into the shape of a cardboard box later.

The present invention provides the following embodiments.

[0028] Figures 1, 2, and 6 show the structural diagrams of the carton creasing device used in carton production in this embodiment. The carton creasing device in this embodiment includes a mounting frame 1. A conveyor slide plate 2 is fixedly connected inside the mounting frame 1. Slide grooves 3 are provided on both sides of the mounting frame 1. Sliding sliders 4 are slidably installed inside each slide groove 3. Screws 17 are installed inside each of the two slide grooves 3 via bearings, and the screws 17 are threadedly connected to the sliding sliders 4. A hand crank 18 is fixedly connected to one end of the screw 17, and the hand crank 18 is located above the mounting frame 1. The surface of one of the screws 17... A drive pulley 19 is coaxially arranged, and a driven pulley 20 is coaxially arranged on the surface of another screw 17. The driven pulley 20 and the drive pulley 19 are connected by belt drive. During the creasing process of the cardboard, the hand crank 18 is turned by hand, and through the belt drive of the drive pulley 19 and the driven pulley 20, the two screws 17 are driven to rotate synchronously. The rotating screws 17 will cause the slider 4 to move up and down in the groove 3. Therefore, the two sliders 4 can drive the creasing structure between them to rise and fall, thereby adjusting the depth of the creasing.

[0029] As shown in Figures 3, 4, and 5, in this embodiment, a guide rail 5 is fixedly connected between two sliders 4. Multiple movable seats 6 are slidably mounted on the guide rail 5.
