Description

Technical Field

[0001] The utility model relates to the field of carton production, and more specifically to a carton mould with adjustable size. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons are three-layer and five-layer, and seven-layer are less used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The lining and face paper are tea board paper and kraft paper, and the core paper is corrugated paper.

[0003] During the production of existing cartons, the carton board needs to be creased before cutting, but the existing carton molds often cannot be adjusted in size and can only be replaced frequently, and the scope of application is relatively low. Based on this, the utility model designs an adjustable size carton mold to solve the above problem. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides a carton mold with adjustable size to solve the problems existing in the above background technology.

[0005] The utility model provides the following technical solution: a carton mold with adjustable size, comprising a base, a support frame fixedly connected to the top of the base, a slide board slidably connected to the inner wall of the support frame, a motor fixedly installed on the top of the slide board, a rotating shaft fixedly connected to the output end of the motor, a sub-gear fixedly connected to the outer wall of the rotating shaft, a group of sub-racks meshed with the sub-gear, a main gear fixedly connected to the bottom end of the rotating shaft, a group of main racks meshed with the main gear, one end of the two main racks away from each other and one end of the two sub-racks away from each other are fixedly connected with a slider, the slider is slidably connected to the bottom end of the slide board, and a creasing knife is fixedly connected to the bottom end of the slider.

[0006] Furthermore, vertical grooves are provided on both sides of the inner wall of the support frame corresponding to the slide plate, and the ends of the slide plate are located in the vertical grooves and are slidably connected thereto.

[0007] Furthermore, a group of hydraulic rods are fixedly installed at the bottom end of the support frame, and the bottom ends of the hydraulic rods are fixedly connected to the slide plate.

[0008] Furthermore, a sliding groove is provided at the bottom end of the slide plate corresponding to the sliding block, and the top end of the slide plate is located in the sliding groove and is slidably connected thereto.

[0009] Furthermore, the four corners of the bottom end of the skateboard are fixedly connected to support columns, the inner wall of the support column is slidably connected to a sliding column, a spring is fixedly connected between the top end of the sliding column and the support column, and the bottom end of the sliding column is fixedly connected to a rubber pad.

[0010] Technical effects and advantages of the utility model:

[0011] 1. The utility model drives the slide plate to move downward along the vertical groove through the hydraulic rod. The rubber pad contacts the carton board first and then the supporting column fits the outer wall of the slide column to continue to move downward and squeeze the spring, thereby achieving a fixed limiting effect on the carton board. As the slide plate continues to move, the indentation knife at the bottom end of the slider indents the carton board.

[0012] 2. The utility model drives the slider and the creasing knife at the ends of the main gear to move away from each other along the slide groove by meshing the two main racks with the main gear. Similarly, the sub-gear meshes the two sub-racks and drives the slider and the creasing knife at the ends of the main rack and the sub-rack to move away from each other along the slide groove. When the motor rotates in the opposite direction, the creasing knives at the ends of the main rack and the sub-rack move closer to each other along the slide groove, thereby realizing the size adjustment of the carton mold, avoiding frequent mold replacement, and having a wider range of applications.
