The invention discloses a welding machine for hollow blow-molded plastic plates. The welding machine comprises a high-frequency host and a clamping device. The clamping device comprises a main workbench, a plurality of positioning supporting blocks, first positioning plates and second positioning plates. The positioning supporting blocks are mounted on the main workbench through guide rail slide blocks at the two ends of each positioning supporting block, and define a polygon. The first positioning plates are mounted at the two ends of the inner side of each positioning supporting block, and the second positioning plates are mounted on the upper portions of the two ends of each positioning supporting block correspondingly. Welding gaps are formed at the junctions at the ends of the positioning supporting blocks, and welding rod guide rail grooves corresponding to the welding gaps are formed in the main workbench. A welding rod is arranged in each welding rod guide rail groove through the corresponding guide rail slide blocks. A plate electrode is arranged corresponding to each welding rod and electrically connected with the high-frequency welding host. According to the welding machine for the hollow blow-molded plastic plates, the hollow blow-molded plastic plates can be welded synchronously into a polygon frame, and edges of a welded plastic product are seamless and free of charring marks.
Description
technical field [0001] The invention relates to the technical field of welding equipment for plastic parts, in particular to a welding machine for hollow blown plastic plates. Background technique [0002] During the production and processing of plastic products, blow molding or extrusion molding are generally used to form plastic products of various shapes and structures. However, many plastic products cannot obtain the required shape and structure through blow molding or extrusion molding. Multiple blow molded parts are welded to form. Plastic welding generally adopts ultrasonic plastic welding machine or high frequency plastic fusion welding machine. The principle of ultrasonic plastic welding is that the generator generates 20KHZ (or 15KHZ) high-voltage, high-frequency signals, and through the energy conversion system, the signal is converted into high-frequency mechanical vibration, which is added to the workpiece of plastic products, and passed through the surface of ...
