Abstract
Description
Technical Field
[0001] The utility model belongs to the field of carton production equipment, and in particular relates to a carton creasing device. Background Art
[0002] The material of cartons is generally corrugated paper. During the production process of cartons, in order to fold them into a box-shaped structure, it is necessary to indent the surface of the corrugated paper, and then fold and press on the indentation to fold the corrugated paper vertically to form the box wall of the carton. The current indentation process basically directly presses the corrugated paper to deform the upper cardboard of the corrugated paper, and then folds and squeezes it from the indentation to form a 90° shape when folding. However, this strong pressing method is likely to cause the generation of reverse stress relative to the extrusion. In the subsequent use of the carton, once the binding of the indentation position is loosened, it will become scattered, and it is difficult to continue to maintain the original shape of the carton.

[0019] Description of the working method of this utility model:
[0020] In the carton creasing device adopting the structure, the machine 1 provides the supporting force of the transmission belt 2, the support seat 3 and the creasing assembly 4 arranged thereon. The corrugated paper enters the device after the previous process, and the corrugated paper is driven / stopped by the transmission belt 2. The slide seat 33 on the support seat 3 is connected with the creasing cylinder 41. The output end of the creasing cylinder 41 is connected with the creasing head 42 through the through hole 31. The creasing head 42 is pressed down toward the corrugated paper on the machine 1 by the driving of the creasing cylinder 41. The two sets of mutually parallel creasing heads 43 on the creasing head 42 act on the corrugated paper to leave creasing marks on the corrugated paper. After the creasing is completed, the creasing is driven again. The cylinder 41 withdraws the pressing head 43 from the area where the corrugated paper is located, and the corrugated paper enters the next folding process under the start of the transmission belt 2. In order to adapt to different indentation positions, the through hole 31 is set to be a long hole shape, and the pushing seat 34 on its output end is pushed by the driving cylinder 35, thereby driving the slide 33 to move on the slide rail 32 to achieve indentation at different positions and complete continuous indentation at different positions. In order to achieve indentation at the left and right ends of the corrugated paper at the same time, two groups of indentation components 4 are set, and then indentation at different positions is performed under the drive of the pushing cylinders 35 on the left and right sides to achieve the indentation effect of unequal sides on the left and right.
[0021] Since the position of the corrugated paper is random and scattered when it is conveyed into the transmission belt 2, in order to limit the corrugated paper in a specific area and ensure that the relative position of the corrugated paper is fixed before each indentation, a limit assembly 5 is provided. The function of the first limit plate 51 is to limit the forward direction of the corrugated paper. The first limit plate 51 is driven by the first cylinder 52 to move up and down in the first limit hole 11, and plays a limiting role in the process of the first limit plate 51 moving up. After the indentation is completed, the first limit plate 51 is retracted and the corrugated paper can be conveyed out by starting the transmission belt 2; and in order to level the left and right ends of the corrugated paper, the second limit plate 53 is driven to move by the second cylinder 54, and the position of the left and right ends of the corrugated paper can be limited. In order to ensure that the second limit plate 53 can move within a certain range, a limit column 55 is provided at the bottom of the second limit plate 53, and the limit column 55 cooperates with the second limit hole 12 on the machine 1 to limit the leveling position of the second limit plate 53.
[0022] The beneficial effect of the utility model is that the production process of two indentations is realized by two sets of mutually parallel indentations 43 on the indentation head 42, so as to ensure that each set of indentations only needs a folding angle of 135° to complete the erection of the corrugated paper, and at the same time, the indentations at different positions on the corrugated paper are realized by the setting of the long hole-shaped through hole 31 and the pushing of the pushing cylinder 35, and the setting of the two sets of indentation components 4 can realize the indentation effect of unequal sides on the left and right, and at the same time, the limiting component 5 is used to limit the forward direction of the corrugated paper, and the second limiting plate 53 is used to realize the leveling of the left and right ends of the corrugated paper.
