Description

Technical Field

[0001] The utility model relates to the technical field of plastic welding, and more specifically, particularly relates to a plastic welding device. Background Art

[0002] Plastic materials are widely used in various industries due to their excellent physical and chemical properties. In the application of plastics, for the connection application of plastic materials, plastic welding technology is one of the key links in the connection application of plastic materials. At present, the welding of plastic materials mainly includes: welding with welding rods and welding without welding rods. That is, when welding with welding rods is used to implement the welding operation of plastic materials, it is usually necessary to make the welding end of the plastic material into a welding seam of a predetermined shape, such as: U-shaped or X-shaped, etc., so that the molten welding rod can drip all over the welding seam to achieve a stable connection between the two plastic materials. When the welding operation of plastic materials is implemented by welding without welding rods, that is, while heating and melting the welding surfaces of the two plastic materials, pressure is applied to the opposite ends of the two plastic materials to make the two plastic materials fuse together at high temperature, thereby achieving the welding operation.

[0003] In the prior art, for the welding of special plastic workpieces, it is usually necessary to manually use rodless welding to complete the welding operation of the plastic workpiece. During the welding process, the welding temperature needs to be accurately controlled to improve the welding quality. When welding plastic materials using existing welding methods, it is usually necessary to manually control the welding temperature based on one's own experience. The welding quality of the plastic material may be affected by excessively high or low welding temperatures, which makes it difficult to meet actual application needs.

[0023] In this embodiment, the clamping structure 2 includes a base body 21 disposed at the top of the base 1, and slide bars 22 are longitudinally disposed at the four ends of the base body 21.
