Specific embodiments
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0021] Such as Figures 1-3As shown in the figure, the utility model provides a technical solution: a creasing device for carton production and processing, which includes a conveying table 1. An electric push rod 3 is installed on the upper side of the conveying table 1 through a bracket 2. The telescopic end of the electric push rod 3 has three modes: a fully retracted state, a fully extended state, and a semi-extended state. In the fully retracted state, both the lower pressing plate 4 and the alignment plate 10 are separated from the conveying table 1. In the fully extended state, the creasing knife 65 on the bottom side of the lower pressing plate 4 and the alignment plate 10 both contact the conveying table 1. In the semi-extended state, the lower pressing plate 4 is suspended, and the alignment plate 10 contacts the conveyor belt on the conveying table 1 to block the carton board, so as to align the carton board on the conveyor belt of the conveying table 1 through the alignment plate 10, ensuring that the lower pressing plate 4 is aligned with the carton board when descending for creasing. The bottom telescopic end of the electric push rod 3 is installed with a lower pressing plate 4. A plurality of threaded holes 5 are opened on the bottom side of the lower pressing plate 4. The plurality of threaded holes 5 are evenly distributed in a rectangle on the bottom side of the lower pressing plate 4. And a freely combinable creasing knife assembly 6 is installed on the bottom side of the lower pressing plate 4 through the threaded holes 5. The carton is conveyed on the conveyor belt of the conveying table 1. After the carton contacts the alignment plate 10, it is recognized by the induction probe 11. The telescopic end of the electric push rod 3 pushes the lower pressing plate 4 to descend, pressing the creasing knives 65 of a plurality of creasing knife assemblies 6 on the carton board surface to form creases on the carton board surface. Then the telescopic end of the electric push rod 3 fully retracts, driving the lower pressing plate 4 to rise tightly, and the moving positioning plate 8, the sliding rod 9, and the alignment plate 10 are lifted together. At this time, the creased cardboard is not blocked by the alignment plate 10 and will be conveyed to the next process along with the conveyor belt on the conveying table 1. The telescopic end of the electric push rod 3 then semi-extends, the lower pressing plate 4 is suspended, and the alignment plate 10 contacts the conveyor belt on the conveying table 1 to block the next carton board, and so on in a cycle, realizing a pipeline-type creasing treatment of the carton board conveyed on the conveyor belt of the conveying table 1. The creasing knife assembly 6 includes a screw 61, a connecting sleeve 62, a limiting ring 63, a connecting plate 64, and a creasing knife 65. According to the crease requirements of the carton, a suitable number of 6 creasing knife assemblies 6 are selected. Rotate the screw 61 so that its top side is connected to the threaded hole 5. The connecting sleeve 62 is squeezed upward through the limiting ring 63 to install the creasing knife 65. A plurality of creasing knives 65 are combined and installed in a straight line. Pressing on the carton can press out a crease. The setting of the connecting plate 64 forms a space at the bottom side of the screw 61, which is convenient for rotating the bottom side of the screw 61. And the top side of the screw 61 is connected to the threaded hole 5, and the limiting ring 63 is connected to the outside of the screw 61. And the limiting ring 63 is sleeved with the groove inside the connecting sleeve 62, and the connecting plate 64 is connected between the connecting sleeve 62 and the creasing knife 65. When installing the creasing knife assembly 6, dock the top side of the screw 61 with the threaded hole 5, and rotate the screw 61 to squeeze the connecting sleeve 62 against the bottom side of the lower pressing plate 4 through the limiting ring 63, so as to install the creasing knife 65 on the bottom side of the lower pressing plate 4. In this way, a plurality of creasing knife assemblies 6 are installed in a straight line on the bottom side of the lower pressing plate 4 to adapt to the size of the carton to be creased. A positioning plate 8 is installed on the rear side of the bracket 2 through a side bracket 7. A plurality of sliding holes are opened on the positioning plate 8 and connected with sliding rods 9. And the bottom ends of the plurality of sliding rods 9 are connected with an alignment plate 10.From the cooperation of the positioning plate 8, the sliding rod 9 and the alignment plate 10, it can be seen that when the telescopic end of the electric push rod 3 is in the fully retracted state, the alignment plate 10 does not contact the conveying table 1, and when it is in the fully extended state, the alignment plate 10 contacts the conveying table 1. In the semi-extended state, the alignment plate 10 contacts the conveying table 1, realizing the front block of the crease of the carton conveyed on the conveying table 1 and no block after the crease. When the lower pressing plate 4 descends and the indentation knife 65 presses on the carton board surface, the sliding rod 9 will slide into the sliding hole on the positioning plate 8, and the alignment plate 10 contacts the positioning plate 8, ensuring that the lower pressing plate 4 descends to indent the carton board. An induction probe 11 is installed on the alignment plate 10. When two or more indentation knife assemblies 6 are installed together, the indentation knives 65 are butted into a straight line. A control panel is installed on the bracket 2 and is electrically connected to the electric push rod 3 and the induction probe 11.
[0022] The operation steps of the present utility model are as follows:
[0023] When installing the indentation knife assembly 6, the top side of the screw rod 61 is docked with the threaded hole 5, and the screw rod 61 is rotated to squeeze the connecting sleeve 62 against the bottom side of the lower pressing plate 4 through the limiting ring 63, realizing the installation of the indentation knife 65 on the bottom side of the lower pressing plate 4. In this way, multiple indentation knife assemblies 6 are installed on the bottom side of the lower pressing plate 4 in a straight line arrangement, adapting to the size of the carton to be indented. The carton is conveyed on the conveyor belt of the conveying table 1. After the carton contacts the alignment plate 10, it is recognized by the induction probe 11. The telescopic end of the electric push rod 3 pushes the lower pressing plate 4 to descend, pressing the indentation knives 65 of multiple indentation knife assemblies 6 on the carton board surface to form an indentation on the carton board surface. When the indentation knife 65 presses on the carton board surface, the sliding rod 9 will slide into the sliding hole on the positioning plate 8, and the alignment plate 10 contacts the positioning plate 8, ensuring that the lower pressing plate 4 descends to indent the carton board. Then, the telescopic end of the electric push rod 3 fully retracts, driving the lower pressing plate 4 to rise tightly, and the moving positioning plate 8, the sliding rod 9 and the alignment plate 10 are lifted together. At this time, the cardboard with the indentation completed is not blocked by the alignment plate 10 and will be conveyed to the next process along with the conveyor belt on the conveying table 1. The telescopic end of the electric push rod 3 then semi-extends, the lower pressing plate 4 is suspended, and the alignment plate 10 contacts the conveyor belt on the conveying table 1 to block the next carton board. In this cycle, the indentation processing of the carton board conveyed on the conveyor belt of the conveying table 1 is realized in a pipeline manner.
