Description

Technical Field

[0001] This invention belongs to the field of thin film processing technology, and in particular relates to a dynamic temperature control adaptive thin film hot melting device. Background Technology

[0002] Thin films typically refer to extremely thin material layers, which are widely used in many fields. Common types include optical films, electronic films, packaging films, biomedical films, and functional films. In the production and processing of thin films, the hot melt device is one of the most important pieces of equipment, mainly used to heat and melt the raw materials of the film. The existing authorization announcement number CN220348806U discloses a raw material hot melt device for polypropylene film production, including a hot melt tank as a whole, a feed pipe connected to one side of the top, a support column fixedly connected to the bottom, a heating device laid on the inner side of the inner wall of the hot melt tank as a whole, and a driving device fixedly installed in the middle of the top of the hot melt tank as a whole. However, it still has the following drawbacks in practical use: 1. The hot melting device mentioned above usually has a temperature sensor and an infrared camera installed inside the melting tank. The temperature sensor detects the melting temperature and the infrared camera monitors the melting quality of the raw materials. However, since the infrared camera is located inside the melting tank for a long time and the internal temperature of the melting tank is high, the lifespan of the infrared camera is short, the maintenance cost is high, and its practicality is low. 2. The hot melt device mentioned above heats and melts the raw materials inside the melting tank through a heating device, and assists in the melting of the raw materials through a main stirring paddle and a secondary stirring paddle. In order to facilitate the control of the melting temperature, it lacks a structure for pre-treating the raw materials during use, which makes it impossible to guarantee the melting speed of the film raw materials. Consequently, the raw materials degrade due to excessive heating time, affecting the product quality.

[0003] To address these issues, we have developed a dynamic temperature-controlled adaptive thin-film hot-melt device. Utility Model Content

The output shaft of the first drive motor drives the crushing roller to rotate, and the film raw material falls between the crushing roller and the filter screen through the guide block. The crushing roller crushes the film raw material, and the crushed film raw material falls onto the rotating plate through the filter screen. At the same time, the high-temperature exhaust gas in the melting tank enters the feeding box through the preheating pipe to preheat the film raw material. After the film raw material is preheated, the hydraulic cylinder drives the U-shaped frame to move, and the U-shaped frame drives the rotating plate to rotate, so that the film raw material on the rotating plate enters the melting tank through the feeding pipe, which facilitates the pretreatment of the film raw material and facilitates the melting and processing of the film raw material.
