Description

Technical Field

[0001] The utility model relates to the technical field of conveying, in particular to a paper feeding device of a die-cutting machine. Background Art

[0002] The die-cutting machine is also called a die-cutting machine, a cutting machine, or a CNC punching machine. It is mainly used for die-cutting, creasing, hot stamping, laminating, and automatic waste discharge of corresponding non-metallic materials, self-adhesive stickers, EVA, double-sided tape, electronics, mobile phone pads, etc. The die-cutting machine uses steel knives, hardware molds, and steel wires to apply a certain amount of pressure through the stamping plate to cut printed products or cardboard into a certain shape. The Chinese utility model patent, authorization announcement number "CN221395681U" discloses a paper feeding structure for a die-cutting machine. This application enables the four sides of the cardboard to be stacked flat, preventing paper jams during transportation, thereby improving the die-cutting efficiency of the die-cutting machine.

[0003] During the use of the above technical solution, when adjusting the limit plate, it is necessary to use bolts to adjust the distance between the limit plate and the first conveyor belt. When the first conveyor belt is conveying, it is necessary to ensure that the distance between the bottom of the limit plate and the first conveyor belt can only pass a piece of cardboard. When tightening the bolts to fix the limit plate, it is also necessary to ensure that the limit plate remains stationary. Simply manually adjusting the height of the limit plate will result in a large number of errors, and it requires multiple people or the use of auxiliary tools to adjust the limit plate, which makes the adjustment effect of the limit plate poor. Therefore, we propose a paper feeding device for a die-cutting machine. Utility Model Content

[0026] The first conveying platform 1 and the second conveying platform 2 are provided with a limit adjustment structure;

[0027] The limit adjustment structure includes two fixed plates 3, a slide rail 7, a front limit plate 6, an installation slide 11 and a limit slide 10. The two fixed plates 3 are fixedly connected to the top of the second conveyor platform 2, the slide rail 7 is fixedly connected to the opposite surfaces of the two fixed plates 3, the installation slide 11 is slidably connected to the side of the slide rail 7 close to the first conveyor platform 1, the installation slide 11 is installed on the slide rail 7 by bolts, and a limit slide groove 12 is provided on the side of the installation slide 11 away from the slide rail 7.

The opposite back surfaces of the two side limit plates 8 are fixedly connected with two limit rods 4. The ends of the four limit rods 4 away from the corresponding side limit plates 8 slide through the corresponding fixed plates 3. The opposite surfaces of the two side limit plates 8 are rotatably connected with multiple rotating columns 9.

[0029] A mounting plate 16 is fixedly connected to the bottom of the first conveyor platform 1, and a second electric push rod 17 is fixedly installed on the side of the mounting plate 16 away from the second conveyor platform 2.
