Description

Technical Field

[0001] The present invention relates to the technical field of cutting machines, and in particular to an automatic numerically controlled cutting machine. Background Art

[0002] In the process of advertising production, advertising boards are often needed. Currently, commonly used advertising boards are plastic boards and acrylic boards. Plastic boards and acrylic boards are widely used because they are easy to process and install, and can adapt to the production needs of advertising signs of various shapes and sizes. At the same time, they have good transparency and glossiness. In addition, in the process of advertising production, the cutting of plastic boards and acrylic boards requires the use of a laser cutting machine. The advantages of laser cutting are its fast speed, burr-free cutting edges and high precision, thereby ensuring the quality of advertising production.

[0003] After the existing cutting machine has cut the advertising board, the cut sheet (the sheet formed into a certain shape) and the original advertising board are still together. Then, the cut advertising board and the cut sheet need to be taken out of the equipment one by one manually, resulting in low overall cutting efficiency. Therefore, corresponding improvements are made to address this problem. Summary of the Invention

[0004] Based on the technical problems existing in the prior art, the present invention proposes an automated CNC cutting machine.

[0005] The lifting mechanism is a bottom end of the lifting mechanism, and the lifting mechanism is a bottom end of the lifting mechanism, and the lifting mechanism is a bottom end of the lifting mechanism. The blanking plate on the top of the guide plate has a notch at the other end, and the advertising board is placed on the upper plate. During cutting, the first slider on the first guide rail and the second slider on the second guide rail will drive the laser head to move, and the laser head will be used to cut the corresponding shape on the advertising board. The cut sheet material falls onto the lower plate through the blanking port. After cutting, the upper plate moves to one side of the feeding port, and the upper plate drives the lower plate to move in the opposite direction through the transmission assembly, and then the lower plate drives the blanking plate to move to the inclined surface. The bottom end of the blanking plate will always be attached to the inclined surface, causing the blanking plate to gradually tilt downward. At the same time, the L-shaped end of the upper plate pushes the sheet material on the lower plate onto the blanking plate, and the sheet material will slide from the notch to the inclined surface, and then fall from the discharging channel. The upper plate transports the advertising board to the feeding port, thereby realizing the separate discharging of the sheet material and the cut advertising board.

[0006] Preferably, a pair of first guide pillars are fixed on the side of the box body away from the material extraction port, and a circular hole for inserting the first guide pillar is opened at one end of the upper plate close to the first guide pillar. Through the cooperation of the first guide pillar and the circular hole, the upper plate can be moved in the horizontal direction.

[0007] Preferably, a pair of second guide pillars are fixed on the side of the box away from the material removal port, and a pair of guide sleeves are fixed on the bottom of the lower plate for the second guide pillars to pass through. Through the cooperation between the second guide pillars and the guide sleeves, the lower plate can be moved in the horizontal direction.

[0008] Preferably, the transmission assembly includes a gear, a first rack and a second rack, the first rack and the second rack are fixed to the rear of the lower plate and the upper plate respectively, and the first rack and the second rack are both engaged with the gear, the gear is fixedly sleeved on a shaft that is rotatably connected to the box body, and when the upper plate moves, the second rack is synchronously driven to move, and the engagement of the second rack drives the gear to rotate, and the gear engages the first rack to cause the lower plate to move in the opposite direction.

[0009] Preferably, the transmission assembly includes a fixed seat fixed on the inner wall of the box body away from the material feeding port, and a shaft column is rotatably connected to the fixed seat, and drums are fixedly sleeved at both ends of the shaft column, and a pull rope is sleeved on the drum, and the two free ends of the pull rope are fixedly connected to the upper plate and the lower plate respectively, and a first spring is sleeved on the second guide column, and the two ends of the first spring are fixedly connected to the box body and the guide sleeve respectively. When the upper plate moves, the pull rope is pulled, and the other end of the pull rope will pull the lower plate, thereby causing the lower plate to move in the opposite direction. When the upper plate resets, the lower plate can be driven to reset under the action of the first spring.

[0010] Preferably, an electric push rod is fixed to the inner wall of the box body away from the material taking port, and the output shaft of the electric push rod is fixedly connected to the upper plate. When the electric push rod is started, the output shaft of the electric push rod moves telescopically, which can drive the upper plate to move in the horizontal direction.

[0011] Preferably, a motor is fixed to the inner wall of the rear end of the box, and the motor output shaft is fixedly connected to the end of the shaft. When the motor is started, the motor output shaft can drive the shaft to rotate forward and reverse, thereby moving the upper plate in the horizontal direction.

[0012] Preferably, a pair of positioning strips distributed on both sides of the blanking port are fixed on the top of the upper plate, a pair of first ribs are fixed on the top of the lower plate, and a pair of second ribs located on the same straight line as the first ribs are fixed on the top of the blanking plate. The advertising board can be positioned between the two by the two positioning strips, and the sheet material falling onto the lower plate can be restricted to the area between the two by the two first ribs, thereby preventing the sheet material from falling off the lower plate.

[0013] Preferably, an opening is provided at the top of the inclined surface. When the sheet material falls from the blanking plate onto the inclined surface, the inclined surface can be vibrated and shaken, thereby assisting the sheet material to slide down the inclined surface and preventing the sheet material from stagnating on the inclined surface.

[0014] Preferably, the inclined surface is formed by an inclined plate that is rotatably connected to the guide plate, a pair of slide rails are fixed to the inner wall of the bottom of the guide plate, a slide seat is slidably connected in the slide rails, a connecting rod is rotatably connected to the top of the slide seat, the top of the connecting rod is rotatably connected to the inclined plate, and the slide seat and the slide rail are connected by a second spring. When the sheet material falls from the blanking plate to the inclined plate, the inclined plate can be vibrated and rotate back and forth slightly under the action of the second spring and the connecting rod, thereby assisting the sheet material to slide off the inclined plate and avoiding the sheet material from stagnating on the inclined plate.
