[0016] like Figures 1-4As shown in the figure, a laser cutting and blanking device includes a bottom plate with mounting holes at its corners. It also includes a first cylinder, a connecting rod, a bearing mechanism, and a pre-tightening component. The first cylinder is fixedly installed on one side of the upper part of the bottom plate. The connecting rod is fixedly connected to the telescopic end of the first cylinder. The bearing mechanism is fixedly connected to one end of the connecting rod. The pre-tightening component is fixedly connected to the bottom of the middle section of the connecting rod. The pre-tightening component is located below the bearing mechanism and slides along the outer wall of the first cylinder as the connecting rod moves up and down. The device is installed at the bottom through the mounting holes. The telescopic movement of the first cylinder drives the connecting rod and the bearing mechanism to move up and down synchronously, adjusting the height of the bearing mechanism to receive parts and reduce the impact after the parts fall. At the same time, the pre-tightening component moves synchronously with the up and down movement of the connecting rod, increasing the movement stability of the connecting rod and also used to adjust the flexible support strength of the bearing mechanism.

[0017] As Figure 1 , Figure 2 and Figure 3 shown in the figure, in order to achieve the buffering after the workpiece falls and at the same time convey, receive, and blank the parts, the bearing mechanism includes a connecting plate, rollers, a conveyor belt, and stoppers. The connecting plate is fixedly connected to one end of the connecting rod. Limiting grooves are opened in the middle of the two side walls of the connecting plate adjacent to the connecting rod. The rollers are rotatably connected in the limiting grooves. The rollers are symmetrically arranged with the connecting plate as the center. The conveyor belt is wound around the outer side walls of the symmetrically arranged rollers. The stoppers are arranged on the outer circumferential sides at both ends of the conveyor belt. The stoppers are symmetrically arranged. A conveying groove is formed between the symmetrically arranged stoppers. A rotary motor is installed on the side wall of the connecting plate and is connected to one of the rollers. Driving the rotary motor to rotate, the symmetrically arranged rollers rotate synchronously through the conveyor belt. The conveyor belt is used to receive the dropped workpieces, making the workpieces fall into the limiting grooves to limit the workpieces and stably convey, receive, and blank them.

[0018] As Figures 2-4 shown in the figure, in order to tighten the upper part of the conveyor belt and increase the flexible support force of the conveyor belt to bear the dropped workpieces, the pre-tightening component includes a collar, a lifting rod, a support plate, a second cylinder, a U-shaped clamp, and a roller. The collar is sleeved on the outer wall of the first cylinder and slides along the axial direction of the first cylinder. One end of the support plate is fixedly connected to the outer wall of the collar. The second cylinder is installed on the upper part of the other end of the support plate. The lifting rod is fixedly connected between the connecting rod and the support plate. The U-shaped clamp is fixedly connected to the telescopic end of the second cylinder. The roller is rotatably connected between the opposite inner side walls of the U-shaped clamp. Driving the second cylinder to extend, the U-shaped clamp is driven to lift the roller, making the roller contact the bottom wall of the conveyor belt and push the bottom wall of the conveyor belt to rise, tightening the upper part of the conveyor belt and achieving the pre-tightening effect when receiving the workpieces.

[0019] Among them, air bags are provided on the upper wall of the connecting plate. The air bags are arranged at equal intervals along the length direction of the connecting plate and are in contact with the bottom wall of the upper part of the conveyor belt. The conveyor belt has elasticity. When the workpiece drops, it impacts the conveyor belt, and the conveyor belt is buffered by the air bags to achieve bearing the dropping of the workpiece.

[0020] When in use, the operator fixes the bottom plate of the device to the table through the mounting hole, and places it under the support plate of the laser cutting machine. The operator drives the first cylinder to extend, so that the bearing mechanism is close to the bottom of the cutting plate to receive the workpiece. At the same time, the collar slides upward along the outer wall of the first cylinder, driving the pre-tightening assembly to rise. The workpiece falls after cutting, and the second cylinder is driven to extend, so that the roller contacts the bottom wall of the conveyor belt and pushes the bottom wall of the conveyor belt to rise, so that the upper part of the conveyor belt is tightened, and the pre-tightening effect is achieved when receiving the workpiece.

[0021] When the workpiece is loaded, it falls into the conveying trough on the conveyor belt, and the workpiece is limited by the symmetrical block, which drives the rotary motor to rotate, so that the symmetrical rollers rotate synchronously through the conveyor belt to guide the workpiece for unloading.

[0022] Although the embodiments of the utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents.
