Description

Technical Field

[0001] The invention belongs to the field of plastic mixing mechanical equipment, and in particular relates to a medicinal plastic packaging material mixing system. Background Art

[0002] Plastic film is widely used as packaging material for various products due to its light weight, high strength and corrosion resistance. Plastic film for pharmaceutical packaging is usually made by mixing plastic raw materials of multiple different components and then further processing. Existing material mixing devices generally use mechanical stirring methods such as stirring blades to directly stir and mix the materials. During the mixing process, some plastics or plastic raw materials cannot be fully melted, which affects the heat transfer, resulting in prolonged mixing time or uneven and insufficient mixing. If the uniformity of material mixing does not meet the production standards, it will lead to poor thermal stability and mechanical properties of the plastic film, uneven appearance color, surface defects, and reduced product quality. The present invention provides a pharmaceutical plastic packaging material mixing system that is energy-saving and environmentally friendly, has more uniform and sufficient material mixing, has a high degree of automation, and effectively improves product quality.

A pressure relief valve is provided on the hopper tube, and the pressure that the pressure relief valve can withstand can be adjusted. When the pressure exceeds, the melted material inside the melting tube will continue to spray out, so that the melted material will be sprayed out intermittently and fully mixed with the unmelted material, so that the packaging material components are mixed more evenly, effectively improving product quality, and being more energy-saving and environmentally friendly.
