Description

Technical Field

[0001] The utility model relates to the technical field of carton processing, in particular to an automatic flat-bed die-cutting machine for carton processing. Background Technique

[0002] The carton die-cutting machine is an important device in carton processing, which is used to cut and indent the cardboard according to the predetermined shape and size, so as to facilitate subsequent folding and forming to produce various specifications of cartons;

[0003] In the prior art: The patent with the authorized publication number CN CN216635565U discloses an automatic flat-bed die-cutting machine for carton processing, including a machine body. A control panel is fixedly connected to the right side of the machine body. A first telescopic mechanism and a second telescopic mechanism are arranged inside the machine body. A pressing plate is fixedly connected to the bottom end of the second telescopic mechanism. A blade is fixedly connected to the bottom end of the first telescopic mechanism. A pushing groove is opened on the upper surface of the machine body. For this automatic flat-bed die-cutting machine for carton processing, through the mutual cooperation between the push plate, the movable rod, the spring groove, the spring and the pushing groove, after the die-cutting is completed, the elastic force of the spring will push the push plate upward, thereby pushing the cardboard upward, which is convenient for removing the processed cardboard, and solves the problem that at present, after the automatic flat-bed die-cutting machine for carton processing completes the die-cutting work, due to the large extrusion force, the cardboard adheres to the surface of the machine, so it is not easy to remove the cardboard;

[0004] This type of automatic flat-bed die-cutting machine for carton processing has the following disadvantages: The distance that the telescopic mechanism drives the blade to extend downward is fixed. If the cardboard to be die-cut is relatively thin, there will be an excess of downward cutting force, which will ultimately be borne by the flat-bed film, resulting in the flat-bed film being damaged too quickly. For this reason, we propose an automatic flat-bed die-cutting machine for carton processing. Content of the Utility Model

[0026] Please refer to Figure 1-6, this embodiment provides a technical solution: an automatic flat-bed die-cutting machine for carton processing, including a frame 1. A flat-bed die 10 is arranged in the middle of the tabletop of the frame 1. It is characterized in that: it further includes a pressing and cutting mechanism 9. A single-chip microcomputer 2 is arranged in the middle of the front side of the frame 1. The input end of the single-chip microcomputer 2 is electrically connected to an external power supply. The pressing and cutting mechanism 9 further includes an electric push rod 91. The electric push rod 91 is arranged in the middle of the top wall of the frame 1. The lower end of the telescopic end of the electric push rod 91 is fixedly connected with a mounting block 92. The input end of the electric push rod 91 is electrically connected to the output end of the single-chip microcomputer 2. A chute 11 is opened in the middle of the rear side wall of the frame 1. A slider 12 is slidably connected in the chute 11. A pull rod 13 is arranged at the front end of the slider 12. The front end of the pull rod 13 is fixedly connected with the rear end of the mounting block 92. An electric conveyor belt 3 is arranged at the right end of the tabletop of the frame 1. The input end of the electric conveyor belt 3 is electrically connected to the output end of the single-chip microcomputer 2. A placement bar 4 is arranged at the right end of the tabletop of the frame 1. A first sliding column 5 is slidably connected to the upper end of the placement bar 4. A pressing plate 6 is arranged at the lower end of the first sliding column 5. A first spring 7 is arranged between the upper end of the pressing plate 6 and the inner wall of the placement bar 4. The first spring 7 is sleeved on the outer surface of the first sliding column 5. The pressing plate 6 and the electric conveyor belt 3 are corresponding up and down. Lift the pressing plate 6 upward by hand. At this time, the pressing plate 6 will squeeze the first spring 7 upward to make it contract. Then put the cardboard to be die-cut into the placement bar 4. At this time, the pressing plate 6 will be pressed against the surface of the belt body of the electric conveyor belt 3 by the resilience of the first spring 7. At this time, turn on the electric conveyor belt 3 through the single-chip microcomputer 2. The electric conveyor belt 3 runs and will convey the cardboard at the upper end to the inside of the retaining pieces 8 around the flat-bed die 10. The retaining pieces 8 are evenly distributed on the upper end of the tabletop of the frame 1. The retaining pieces 8 are arranged at the edge of the flat-bed die 10;

[0027] Press-cutting mechanism 9: It includes an installation block 92 and a limit component 95. The middle of the top wall of the frame 1 is provided with the installation block 92. The bottom of the installation block 92 is provided with evenly distributed second sliding columns 93. The bottoms of the two second sliding columns 93 are both slidably connected to the sliding holes at the upper ends of a press-cutting block 96. Uniformly distributed limit grooves 97 are opened on the outer arc surfaces of the two second sliding columns 93. The limit component 95 includes a sliding block 954. The sliding block 954 is slidably connected between the two second sliding columns 93. A groove is opened in the middle of the sliding block 954. Symmetrically distributed limit blocks 951 are slidably connected in the groove. The limit blocks 951 are all installed in cooperation with the horizontally adjacent limit grooves 97. The press-cutting mechanism 9 further includes second springs 94. Evenly distributed second springs 94 are provided between the lower end of the sliding block 954 and the upper end of the press-cutting block 96. The second springs 94 are all sleeved on the outer surfaces of the second sliding columns 93. The limit component 95 further includes third springs 952 and third sliding columns 953. The two limit blocks 951 are both slidably connected to a third sliding column 953. A third spring 952 is provided between the two limit blocks 951. The third spring 952 is sleeved on the outer surface of the third sliding column 953. Then, the electric push rod 91 is turned on through the single-chip microcomputer 2. Since the press-cutting block 96 and the flat pressing die 10 are in corresponding upper and lower positions, the electric push rod 91 drives the press-cutting block 96 to press down and cut the cardboard. While pressing down, the pull rod 13 drives the slider 12 to slide downward synchronously. At the same time, according to the distance between the press-cutting block 96 and the flat pressing die 10 and the thickness of the cardboard, the travel distance of the telescopic end of the electric push rod 91 is regulated through the single-chip microcomputer 2. During the downward pressing process, the lower end of the press-cutting block 96 will contact the cardboard, and at the same time, it will be squeezed downward under the drive of the electric push rod 91 to cut the cardboard. During the downward squeezing process, the two second sliding columns 93 will slide into the press-cutting block 96, thereby squeezing the second springs 94. Since the height adjusted by the sliding block 954 is the thickness of the cardboard, when the upper end of the press-cutting block 96 contacts the lower end of the sliding block 954, the cardboard is press-cut. After the press-cutting is completed, the cardboard is taken off and the next piece of cardboard is continued to be press-cut. If it is necessary to replace a thicker cardboard, the two limit blocks 951 can be simultaneously squeezed inward by hand, so that the two limit blocks 951 slide into the groove simultaneously and squeeze the third spring 952, so that it leaves the limit groove 97, thereby releasing the locking of the sliding block 954. After adjusting the sliding block 954 to the corresponding height, the limit blocks 951 are released, so that the limit blocks 951 return to their positions under the action of the third spring 952 and are inserted into the limit groove 97 again to complete the locking of the sliding block 954. The downward pressing distance is adjusted according to the thickness of the cardboard to avoid the problem of damage to the flat pressing film 10 caused by excessive downward pressure, thereby improving the service life of the flat pressing film 10.

[0028] The working principle of an automatic flat pressing and die-cutting machine for carton processing provided by the utility model is as follows: When carton processing and die-cutting are required, during carton processing and die-cutting, the staff first manually lift the pressing plate 6 upwards. At this time, the pressing plate 6 will squeeze the first spring 7 upwards to make it contract. Then, the cardboard to be die-cut is placed in the placement column 4. At this time, the pressing plate 6 will be pressed by the resilience of the first spring 7 to press the cardboard on the surface of the belt body of the electric conveyor belt 3. At this time, the electric conveyor belt 3 is turned on through the single-chip microcomputer 2. When the electric conveyor belt 3 operates, it will convey the cardboard at the upper end to the inside of the baffle 8 around the flat pressing die 10 to the left. Then, the electric push rod 91 is turned on through the single-chip microcomputer 2. Since the pressing block 96 and the flat pressing die 10 are corresponding up and down, the electric push rod 91 drives the pressing block 96 to press down and cut the cardboard. While pressing down, the pull rod 13 drives the slider 12 to slide down synchronously. At the same time, according to the distance between the pressing block 96 and the flat pressing die 10 and the thickness of the cardboard, the travel distance of the telescopic end of the electric push rod 91 is regulated through the single-chip microcomputer 2. During the pressing-down process, the lower end of the pressing block 96 will contact the cardboard, and at the same time, it will be pressed down under the drive of the electric push rod 91 to cut the cardboard. During the pressing-down process, the two second sliding columns 93 will slide into the pressing block 96, thereby squeezing the second spring 94. Since the height adjusted by the sliding block 954 is the thickness of the cardboard, when the upper end of the pressing block 96 contacts the lower end of the sliding block 954, the pressing of the cardboard is completed. After the pressing is completed, the cardboard is taken off and the next piece of cardboard is continued to be pressed. When it is necessary to replace a thicker cardboard, the two limit blocks 951 can be manually squeezed inwards at the same time, so that the two limit blocks 951 slide into the groove at the same time and squeeze the third spring 952 to make it leave the limit groove 97, thereby releasing the locking of the sliding block 954. After adjusting the sliding block 954 to the corresponding height, the limit blocks 951 are released, and the limit blocks 951 return to their positions under the action of the third spring 952 and are inserted into the limit groove 97 again to complete the locking of the sliding block 954.

[0029] It should be noted that in the above embodiments, the single-chip microcomputer 2 disclosed can be a 51 series single-chip microcomputer, the electric push rod 91 can be an LAP series electric push rod, and the electric conveyor belt 3 can be freely configured according to the actual application scenario. The single-chip microcomputer 2 controls the operation of the electric push rod 91 and the electric conveyor belt 3 by using the commonly used methods in the existing technology.

[0030] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, are similarly included in the patent protection scope of the present utility model.
