[0002] Plastic products are widely used in modern industry and daily life. Their connection and assembly often require the use of welding technology. Traditional plastic product connection methods such as gluing and mechanical connection have some limitations. Gluing connection may face problems such as glue aging, insufficient strength, and environmental protection issues; mechanical connection may increase the weight and cost of the product, and stress concentration is likely to occur at the connection part. With the continuous expansion of the application fields of plastic products, the requirements for connection quality and efficiency are increasing day by day. Welding technology has gradually become an important means of plastic product connection because it can achieve high-strength, good-sealing, and beautiful-appearance connections. Welding technology heats the plastic to make it partially melt, and then fuses them together under pressure to form a firm connection. Therefore, there is an urgent need for a plastic product welding device capable of preventing dislocation in the market.
[0003] However, the existing technology still has the following problems:
[0004] First of all, most of the existing plastic product weldings do not have a fixing device, resulting in the shaking of raw materials during welding. The shaking of raw materials will cause uneven heat and pressure distribution at the welding part, making the strength of the welded part inconsistent and prone to breakage at the weak points.
[0005] Secondly, when most existing plastic products are welded, the raw materials are directly moved for docking, but directly moving the raw materials will lead to inaccurate positioning, which may result in poor welding quality and affect the connection strength and sealing performance.
[0006] In view of the above problems, the inventor proposes a plastic product welding device capable of preventing dislocation to solve the above problems. Content of the Utility Model
