Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic welding technology, specifically to a tooling fixture for post-processing plastic products. Background Technology
[0002] In the co-extrusion or compounding process of multi-colored plastics, if the process parameters are not properly controlled, the interfacial bonding force between different colored plastic layers will be insufficient. When subjected to external forces during use, or after the product surface ages, cracks are likely to occur at the interface.
[0003] If the interface surface of plastic products cannot form an effective weld after welding or fusion, they are prone to cracking during product use.
[0004] To address the cracking issue after welding and fusion of various plastic products, the industry has used baking and natural gas flame treatment methods. However, these methods each have their own drawbacks and cannot perfectly solve the cracking problem while ensuring the product's appearance.
[0005] Baking plastic products consumes a lot of energy, requires a large area of equipment, and the baking temperature cannot exceed the melting temperature of the plastic products. Gaps still exist on the surface of the plastic seams, and it cannot completely solve the problem of cracking caused by environmental factors during product use.
[0006] Using natural gas flame treatment can lead to carbon buildup and contamination of the product surface, making it unsuitable for products with high surface quality requirements. Furthermore, the burner used in natural gas flame combustion is relatively thick, with a diameter of over 10mm, resulting in a large flame diameter. When the natural gas flame is used to weld seams, it can cause irreversible damage to the product surface.
[0007] To address the shortcomings of existing methods, a robotic approach is used to grasp a flame device for plastic welding. However, this approach has the following drawbacks:
[0008] During welding, the product is heated by a flame, and the heat is transferred to the ferrule. If the ferrule temperature is too high, it can damage the product that has just been installed and is about to be welded. At the same time, when changing product models, the tooling supporting the product is slow to change, reducing production efficiency. Utility Model Content
