[0002] With the development of social economy, plastic products have gradually become an important part of our production and life. For some plastic products with high requirements for air tightness and water tightness, they often need to be manually welded after injection molding during production. However, the manual welding method not only consumes a lot of manpower and material resources, but also has low production efficiency, which is not conducive to continuous production. At present, there are also rotary melting machines for welding plastic workpieces. The rotary melting machine is a welding device that drives the plastic workpiece to rotate at high speed and generate heat through friction to melt the surfaces of the two plastic workpieces to achieve the welding effect. However, the existing rotary melting machine is not capable of positioning the relative position of the plastic workpiece, resulting in incomplete welding of the plastic workpiece and large welding precision deviation, which causes the workpiece to fail to meet the welding and sealing requirements and be reworked or scrapped, with a low pass rate and high production cost, which is not conducive to modern production.

After the fixing device has fixed the product, the rotary melting motor is used to rotate and adjust the position of the rotary melting head. When the positioning sensor on the outer wall of the rotary melting head and the positioning sensor on the top of the platform are relative, the rotary melting motor stops rotating, and the cylinder extends to drive the rotary melting head to descend through the upper mounting plate, the connecting pipe, the connecting rod and the lower mounting plate. When the rotary melting head and the product are completely fixed, the rotary melting head and the product are completely fixed. After full contact, the rotary melting motor rotates again to drive the rotary melting head to rotate and start rotary melting welding. After rotary melting is completed, when the two positioning sensors are relative to each other again, the rotary melting motor stops rotating and the cylinder shortens to drive the rotary melting head and the product to complete rotary melting welding. This can realize automatic positioning of the rotary melting welding product and avoid the lack of precision caused by manual operation. After the rotary melting is completed, the clamping device clamps the product again, and after the fixed telescopic rod contracts to finish fixing the product, the clamping device removes the product for rotary melting of the next product. The structure of the connecting pipe and the connecting rod allows the rotary melting head and the rotary melting motor to be easily removed for inspection and maintenance.
