[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-5 As shown, a waste removal device for paper die-cutting includes a die-cutting machine body 1, and a separation mechanism for distinguishing finished products and waste materials of die-cut paper is connected to the rear side of the die-cutting machine body 1.

[0026] In this embodiment: the separation mechanism includes a waste removal box 21 connected to the rear side of the die-cutting machine body 1. A moving component is provided through the waste removal box 21 and the die-cutting machine body 1. A moving frame 24 is provided on the moving component. A lifting component is provided at the lower end of the moving frame 24. A mounting frame 28 is fixed at the lower end of the lifting component. A support plate 29 is fixed at the lower end of the mounting frame 28. Waste adsorption rods 211 are vertically arranged at the four corners of the support plate 29. A spring 212 is sleeved on the outer diameter of the waste adsorption rod 211 below the support plate 29. A flange is provided on the upper part of the waste adsorption rod 211 above the support plate 29. Through holes are provided at intervals on the support plate 29. Finished product adsorption rods 210 are provided in the through holes. The upper ends of the finished product adsorption rods 210 and the waste adsorption rods 211 are independently connected to negative pressure air source pipes. A waste support component and a finished product support component are provided in the waste removal box 21. The waste adsorption rods 211 and the support plate 29 are connected to each other. The plate 29 is slidably connected, and the outer diameter of the finished product adsorption rod 210 is provided with a threaded groove. Nuts are installed on the finished product adsorption rod 210 on the upper and lower sides of the support plate 29 to facilitate the adjustment and control of the position of the finished product adsorption rod 210. The negative pressure air source pipe is a serpentine hose. After the paper is die-cut, the moving component moves the mounting frame 28 to the upper side of the die-cut paper inside the die-cutting machine body 1, so that the lifting component pushes the mounting frame 28 to move downward as a whole. The lower end of the waste adsorption rod 211 first contacts the waste around the paper. When it continues to move downward, the waste adsorption rod 211 squeezes the spring 212 to move upward until the finished product adsorption rod 210 contacts the finished paper. The negative pressure air source pipe is connected to the air source, so that the finished product adsorption rod 210 and the waste adsorption rod 211 adsorb the paper. Then the lifting component lifts the mounting frame 28 and moves the moving frame 24 to the waste support component and the finished product support component respectively for unloading.

[0027] The moving component includes a lead screw 22 and a slide column 23 that run longitudinally through the waste removal box 21. One end of the lead screw 22 is connected to a servo motor 25. The moving frame 24 is mounted on the lead screw 22 and the slide column 23 and slides within the waste removal box 21 and the die-cutting machine body 1. The lead screw 22 is rotatably connected to the waste removal box 21 and the die-cutting machine body 1. The lead screw 22 is threadedly connected to the moving frame 24. The moving frame 24 is slidably connected to the slide column 23. The servo motor 25 drives the lead screw 22 to rotate, causing the lead screw 22 to push the moving frame 24 to move within the waste removal box 21 and the die-cutting machine body 1 under the limit of the slide column 23, thereby controlling the displacement of the die-cut paper.

[0028] The lifting assembly includes a cylinder 26 vertically fixed on a movable frame 24, with guide posts 27 on both sides of the cylinder 26. The lower ends of the cylinder 26 and the guide posts 27 are fixedly connected to the mounting frame 28. The guide posts 27 are slidably connected to the mounting frame 28. The cylinder 26 extends and retracts to push the mounting frame 28 up and down under the limit of the guide posts 27, which facilitates the control of the height position of the finished product adsorption rod 210 and the waste material adsorption rod 211.

[0029] The waste support assembly includes a first electric telescopic rod 213 vertically mounted on the inner wall of the waste collection box 21, with a waste placement plate 214 installed at the lower end of the first electric telescopic rod 213. The finished product support assembly includes a second electric telescopic rod 215 vertically mounted on the inner wall of the waste collection box 21, with a finished product placement plate 216 fixed at the lower end of the second electric telescopic rod 215. The waste placement plate 214 and the finished product placement plate 216 slide up and down inside the waste collection box 21. A waste discharge port 202 opposite to the waste placement plate 214 is opened on the side wall of the waste collection box 21, and a finished product discharge port 201 is opened at the rear end of the waste collection box 21 to facilitate the removal of the paper placed on the waste placement plate 214 and the finished product placement plate 216. The position of the waste placement plate 214 is controlled by the extension and retraction of the first electric telescopic rod 213, and the position of the finished product placement plate 216 is controlled by the extension and retraction of the second electric telescopic rod 215, which facilitates the receiving of the paper.

[0030] The working principle and usage process of this utility model are as follows: After the paper is die-cut by the die-cutting machine body 1, when the paper is conveyed to the upper side of the separation mechanism, the cylinder 26 extends and pushes the mounting frame 28 to move downward under the limit of the guide column 27. The lower end of the waste material adsorption rod 211 first contacts the waste material around the paper. As it continues to move downward, the waste material adsorption rod 211 compresses the spring 212 and moves upward until the finished product adsorption rod 210 contacts the finished paper. The negative pressure air source pipe is connected to the air source, so that the finished product adsorption rod 210 and the waste material adsorption rod 211 adsorb the paper. The cylinder 26 is lifted upward, and the finished product adsorption rod 210 first lifts the finished paper until it is separated from the waste paper. Then, the waste suction rod 211 sucks up the waste paper, and the servo motor 25 drives the lead screw 22 to rotate, so that the lead screw 22 pushes the moving frame 24 to move into the waste cleaning box 21 under the limit of the sliding column 23. When it moves to the upper side of the waste placement plate 214, the negative pressure air source in the waste suction rod 211 is turned off, and the waste paper is placed on the waste placement plate 214. Then it continues to move to the upper side of the finished product placement plate 216, and the negative pressure air source in the finished product suction rod 210 is turned off, and the finished paper is placed on the finished product placement plate 216. After that, the first electric telescopic rod 213 and the second electric telescopic rod 215 both move downward to the thickness of the paper, which is convenient for the next placement.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
