Description

Technical Field

[0002] Plastic film is widely used as packaging material for various products due to its light weight, high strength, corrosion resistance and other characteristics. Plastic film used for pharmaceutical packaging materials is usually made by mixing plastic raw materials of multiple different components and then further processing.

When the hydraulic plug is compressed, the temperature inside the melt pipe is more likely to rise, and exceeds the temperature under normal pressure, which is more conducive to material melting and energy saving. A pressure relief valve is provided at its lower part, and it will spray when the pressure exceeds its tolerance value. 2. On the basis of the technical features of technical effect 1, when the hydraulic cylinder retracts the hydraulic rod to the bottom of the hydraulic cylinder, the hydraulic plug does not block the connection between the feed pipe and the plug barrel; when the hydraulic plug pushes the material into the melt pipe, the hydraulic plug blocks the connection between the feed pipe and the plug barrel. At this time, a certain degree of vacuum is formed in the front of the hot melt pipe and the plug barrel. When the hydraulic plug withdraws from the feed pipe, the material inside the feed pipe is pushed into the plug barrel under the action of the air pressure difference, which can effectively prevent the material inside the feed pipe and the winding pipe from forming a bridge. 3. A hot melt screen is installed in the melting pipe, and the unmelted material is on the hot melt screen, while the melted material falls into the melting hopper; a pressure relief valve is installed on the melting hopper, which will open after a certain pressure, and the melted material will burst into the mixing bin under the action of pressure difference. This feeding method will make the material more dispersed, so that the easy-to-melt and difficult-to-melt materials can be mixed more evenly, effectively improving product quality and being more energy-saving and environmentally friendly.
