Description

Technical Field

[0001] The utility model belongs to the technical field of paper clamping of a die-cutting machine, and particularly relates to a paper clamping and stacking device of a die-cutting machine. Background Art

[0002] The paper clamping and stacking device of a full-automatic die-cutting machine is a device for automatic paper feeding. Its main function is to suck and transport paper so that it can be accurately and efficiently fed into the die-cutting position of the die-cutting machine. The adsorption manipulator usually includes a plurality of suction cups, and these suction cups generate negative pressure through a vacuum system to firmly adsorb the paper. The adsorption manipulator usually works in cooperation with the paper feeding part of the die-cutting machine. Through automatic control, it realizes the automatic transportation of paper, reduces manual intervention, and improves production efficiency. This device can be synchronized with the working process of the die-cutting machine, avoid the equipment from idling, improve the effective utilization rate of the equipment, and save labor costs at the same time. Generally speaking, the paper adsorption manipulator is an important functional component in a full-automatic die-cutting machine. It improves the efficiency and accuracy of the die-cutting work through automatic operation.

[0003] The paper clamping and stacking device of a full-automatic die-cutting machine usually refers to an adsorption device in the paper transportation process. It adsorbs the paper through suction cups to ensure the stability of the paper during the feeding process into the die-cutting machine, and prevent the paper from sliding or shifting during the transmission process, thereby ensuring the die-cutting accuracy. The adsorption manipulator can accurately control the position of the paper and cooperate with the photoelectric alignment system of the machine to ensure that each cardboard can be accurately sent to the die-cutting position, which is crucial for improving the die-cutting quality and efficiency. The automatic adsorption manipulator can significantly improve production efficiency, reduce manual operation, and realize high-speed and continuous paper transportation. The adsorption manipulator can adapt to papers with different thicknesses and materials to ensure that various types of cardboard can be effectively adsorbed and fed into the die-cutting machine. Through precise control, it reduces the generation of waste products caused by inaccurate paper positioning, thereby reducing production costs. Some adsorption manipulators have an anti-obstacle function. When detecting abnormalities in paper or other objects, they can stop the machine in time to avoid equipment damage and safety accidents. In the actual application of the die-cutting machine, the adsorption manipulator is a key component to ensure the die-cutting quality and efficiency, and is of great significance for improving the automation level and production efficiency of the entire printing and packaging industry. The problems existing in the above technologies are: when using the adsorption robotic arm to clamp and stack paper for the die-cutting machine, first, it is necessary to assemble and fix the adsorption robotic arm to the base to ensure the stability of the adsorption robotic arm during use. However, the adsorption robotic arm and the base need to be connected and fixed through multiple connecting parts and fixing parts, resulting in the need for users to spend a long time and energy, thus reducing the assembly effect of the adsorption robotic arm and the base.

During the movement of the transmission rod, the moving block will be driven to move and the second tension spring will be stretched. During the movement of the moving block, it will contact the surface of the traction rod and apply force to the traction rod. After the traction rod is stressed, it will rotate at the connecting point of the rotating shaft of the square plate. When the traction rod rotates, it will contact the inner wall of the pull rod and drive the pull rod to move accordingly. During the movement of the pull rod, the first tension spring will be stretched and the positioning rod will be driven to move. After the positioning rod moves to a suitable position, the adsorption manipulator is docked with the base.
