Weight increment and weight loss integral mixing device

Abstract

The invention provides a weight increment and weight loss integral mixing device, and belongs to the technical field of plastic extrusion. The weight increment and weight loss integral mixing device comprises storage devices, a weighing and metering device, a mixing device, an extruding device and a traction device; and the weighing and metering device includes metering valves and a weighing hopper. Raw materials are stored in multiple storage devices; the metering valves are respectively arranged between all the storage devices and the weighing hopper; the quantity of each raw material entering the weighing hopper is controlled in proportion; the weighing hopper is used for weighing; a closing valve of the weighing hopper is opened to precisely control the quantities of the raw materials entering the mixing device; a second weighing sensor further monitors the quantity of the mixed raw materials entering from the mixing device to the extruding device, so that the precise control of weight in unloading is realized, and the waste of the raw materials is prevented; finally, extruded products are pulled through the traction device; and the rotating speed of an extrusion screw rod in an extruder and the traction speed of the traction device are adjusted to further guarantee the product quality.

Description

technical field [0001] The invention relates to the technical field of plastic extrusion, in particular to an integrated mixing device for weight gain and weight loss. Background technique [0002] With the development of the plastic industry, plastic products have become an indispensable part of people's production and life, and with the development and utilization of plastic technology, the performance of plastic products is getting higher and higher, and because of the low cost of plastic products, Sufficient raw materials and light weight make the market of plastic products continue to expand. As the main industry of the plastic industry, the plastic extrusion industry has also become the focus of attention. [0003] However, due to the continuous expansion of the competitive advantages of plastic products, the market for plastic products is reflected, so for the plastic extrusion industry, the competition among various enterprises has become increasingly fierce; and, d...

Problems solved by technology

[0003] However, due to the continuous expansion of the competitive advantages of plastic products, the market for plastic products is reflected, so for the plastic extrusion industry, the competition among various enterprises has become increasingly fierce; and, due to people's acceptance of new products The degree is getting higher and higher, and the market of the plastic extrusion industry is changing faster and faster. Conventional plastic products can no longer meet people's requirements for product quality.

[0004] For traditional plastic extruded products, because there is no precise batching and rice weight control device in the feeding system of the extruder, the meter weight of the material cannot be controlled, resulting in poor quality of the plastic products extruded by the extruder. The waste of raw materials is large, and it is difficult to meet the requirements of modern people for plastic products; and with the rapid development of multi-layer co-extrusion technology and the continuous improvement of automation and intelligence in product production, traditional plastic extruders have been unable to meet The development needs of modern industry, so it is necessary to develop equipment that can strictly control the meter weight and improve product quality

[0005] To sum up, the existing plastic extruders lack accurate batching and meter weight control devices, cannot strictly control the meter weight of the blanked material, and the produced products are of poor quality and wasteful.
