The invention discloses a human hand protection device of a high-frequency welding machine. The human hand protection device comprises a cross beam, an air cylinder, a lifting column, a cylinder ejector rod, a connecting plate, microswitches, a compression spring, a welding die head and a height limiting device, and is characterized in that the bottom of the compression spring is fixed on the connecting plate, the welding die head and the lifting column are fixed on the upper surface of the compression spring together, after the gravity of the welding die head and the gravity of the lifting column are balanced with the elasticity of the compression spring, the welding die head and the connecting plate are kept at a certain distance, the two ends of the connecting plate are correspondingly provided with the microswitches, trigger heads of the microswitches and the welding die head are in a zero distance, once the welding die head touches the hand, the force balance of the welding die head is broken, the microswitches are started to control circuits, the ejector rod of the air cylinder is controlled to stop descending, so that the safety of the human hand is protected. The human hand protection device has the beneficial effects that a mechanical force balance principle is adopted in the whole machine, so that the human hand is protected, the triggering flexibility is high, and the device is very reliable as well.
Description
technical field [0001] The invention relates to a high-frequency welding machine for splicing PVC composite cloth, in particular to a hand protection device for the high-frequency welding machine. Background technique [0002] PVC composite fabrics have been widely used. In practical applications, they often need to be spliced together. The best splicing equipment is a high-frequency welding machine. The PVC composite fabrics that need to be welded can be brought to the workbench of the high-frequency welding machine, and the splicing Stacked together for high-frequency welding. The existing high-frequency welding machine does not have a hand protection device. After the PVC composite cloth is placed on the workbench, when the high-frequency welding head descends, it is easy to crush the hands of the people who did not leave the workbench in time. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a high-sensitivity high...
