Description

Technical Field

[0002] The heat shrink assembly devices for hoses and heat shrink sleeves in existing heat shrink stations mostly use a separate lamp tube or hot air gun heating structure. This structure directly irradiates a high-heat beam onto the surface of the heat shrink sleeve, or blows a hot air flow toward the heat shrink sleeve. This makes it easy for the heat shrink tube to produce unstable and uneven stretching due to uneven heating during the heat shrink process, which in turn causes the trend of the 0PF hose to change, affecting the product installation during subsequent processing. For example, the invention patent with the authorization announcement number CN116373326B discloses a mobile heat shrink device for assembling a metal clamp and a heat shrink sleeve, which belongs to the technical field of hose heat shrink devices, including a workbench, a base plate mechanism, a product fixing mechanism, a detection mechanism and a moving mechanism. The base plate mechanism includes a base plate and a guide rail, and the guide rail is connected to the workbench.
