Description

Technical Field

[0001] This utility model relates to the technical field of cardboard processing equipment, and in particular to an automatic paper feeding and creasing device. Background Technology

[0002] Cardboard creasing is a processing technique that uses mechanical pressure to create grooves of appropriate depth on the surface of cardboard, providing precise guidance for subsequent folding. The principle is to use creasing wires and a bottom die to apply pressure to specific areas of the cardboard, causing the fibers to deform and form creases. For example, the Chinese utility model patent disclosed in publication number CN222329169U, "Crimping Machine for Packaging Cardboard," has a mounting plate with several pressing rollers rotatably mounted on its bottom, located on one side of the creasing knife and above the conveyor belt. The mounting plate is positioned between the limiting grooves of two mounting frames, and a stop plate is elastically connected inside the receiving groove of the limiting groove. By inserting the mounting plate between the stop plates of different heights, the height of the mounting plate can be adjusted, thereby adjusting the distance between the pressing rollers and the conveyor belt, and thus adjusting the pressing position. Therefore, although this application can crimp cardboard, it can only perform a single linear crimping operation on the cardboard and cannot perform crimping operations on different positions on the cardboard. At the same time, it cannot perform double-sided crimping operations on some thicker cardboard. Utility Model Content

[0003] The purpose of this invention is to provide an automatic paper feeding and creasing device that can effectively solve the problems in the background art.

Multiple second guide posts 17 are fixedly connected inside the second frame 15, and a second Z-axis moving frame 19 is slidably connected between the multiple second guide posts 17. The lower indentation tool 20 is fixedly connected to the side of the second Z-axis moving frame 19 away from the second guide posts 17.

[0015] like Figures 1-2 As shown, the middle part of the partition 3 has a hollow structure. The partition 3 is set as a hollow structure to support the cross support plate 21 and at the same time realize the smooth displacement of the cross support plate 21 on the partition 3.

[0016] like Figures 1-4As shown, a first motor 6 is fixedly connected to the top of the first frame 5. The first motor 6 is electrically connected to an external main controller via a cable. A first lead screw 8 is rotatably connected to the first frame 5 located between two first guide columns 7. The top of the first lead screw 8 is fixedly connected to the output end of the first motor 6 via a coupling. The first lead screw 8 is also threadedly connected to the first Z-axis moving frame 9. The first motor 6 drives the first lead screw 8 to rotate within the first Z-axis moving frame 9, which can control the vertical movement of the first Z-axis moving frame 9. This allows the first Z-axis moving frame 9 to drive one end of the upper creasing knife 10 to abut against the cardboard. Two connecting rods 22 are fixedly connected to one side of the first frame 5. A cross support plate 21 is fixedly connected to the top of the slide table 14. Two of the cross support plates 21... The ends are fixedly connected to the corresponding connecting rods 22. The cross support plate 21 is used to support the cardboard at the creasing position to ensure the stability of the creasing operation. The slide table 14 and the cross support plate 21 are respectively provided with through holes at their center positions to realize the movement of the lower creasing knife 20, and then cooperate with the upper creasing knife 10 to realize the double-sided synchronous creasing operation of thicker cardboard.

[0017] It should be noted that this utility model is an automatic paper feeding and creasing device. During operation, its multi-directional screw moving platform 4, in conjunction with the first frame 5 and connecting rod 22, drives the cross plate 21 closer to the cardboard conveyor 2. Then, the cardboard conveyor 2 transports the cardboard to the cross plate 21. The controller, through a programmed setting, controls the movement of the multi-directional screw moving platform 4, which, via the first frame 5 and connecting rod 22, drives the cross plate 21 to move. This causes the cross plate 21 to move the cardboard to the center of the partition 3, placing the four corners of the cardboard on the protruding structures at the top corners of the partition 3. Multiple pneumatic clamps inside the equipment frame 1 then simultaneously fix the four corners of the cardboard. Following the same principle, the main controller controls the operation of the multi-directional screw moving platform 4, driving... The first frame 5 is adjusted so that the upper creasing knife 10 can be aligned with the area on the cardboard that needs creasing. The first motor 6 is started, driving the first lead screw 8 to rotate. The first Z-axis moving frame 9 moves downward along the first guide post 7, and the upper creasing knife 10 descends accordingly, contacting the surface of the cardboard. Simultaneously, the second motor 16 drives the second lead screw 18 to rotate, and the second Z-axis moving frame 19 moves upward along the second guide post 17. The lower creasing knife 20 passes through the through hole of the slide table 14 and the cross support plate 21, pushing upward from below the cardboard. The upper creasing knife 10 and the lower creasing knife 20 work together, one above the other. Furthermore, when the first frame 5 moves, the connecting rod 22 moves the cross support plate 21 below the cardboard. The sliding sleeve 12 slides on the Y-axis guide shaft 11, and the slide table 14 moves on the X-axis guide shaft 13, ensuring accurate creasing position.
