Multifunctional double-order melting method efficient production equipment and process

Abstract

The invention provides multifunctional double-order melting method efficient production equipment and process, the equipment comprises a rack, a material storage device, a weighing device, a material collecting device, a mixing mechanism, a banburying mechanism, an extruding mechanism and a follow-up mechanism, and the process comprises the steps that materials are put into the material storage device, and after being metered by the weighing device, the materials are fed into the extruding mechanism; materials are fed into the mixing mechanism through the material collecting device to be primarily stirred and mixed, the evenly-mixed mixture is internally mixed and plasticized, then enters the extrusion mechanism in a semi-molten state, is heated and stirred in the extrusion mechanism and then is extruded in a molten state to be subjected to follow-up requirements such as tape casting or granulation, and the materials are formed through one-time machining. And compared with traditional equipment, material molecular structure changes caused by secondary or multiple heating plasticization of the material are reduced, and secondary pollution of the material is more effectively avoided.

Description

technical field [0001] The application relates to the technical field of breathable film production, in particular to a multi-functional double-stage melting high-efficiency production equipment and process. Background technique [0002] Breathable membranes are widely used in baby diapers, sanitary napkins and other personal hygiene products, such as medical clothing, warm pads, medical protective clothing, breathable rainproof cloth, raincoats, food packaging, crop preservation, building waterproofing, drying bags and other fields. [0003] In the field of breathable film production technology, blow molding and casting are two commonly used processes. The breathable film produced by blow molding has more advantages in protecting the contents of the package, and is better than cast in terms of tensile strength. The breathable film produced is better, but it has the limitations of the production process and the insurmountable defects of the product. For example, the blow mol...

AI Technical Summary

Problems solved by technology

[0008] Further, the feeding mechanism includes a plurality of storage devices for storing various component materials, which solves the problem of inaccurate weighing of the weighing device at the lower end due to the disparity in the ratio of raw materials, and there is no need to repeat weighing Taking materials saves a lot of manpower and time; the lower end of each storage device is correspondingly provided with a weighing device for weighing the added materials, and the weighing device is preferably a high-precision loss-in-weight scale with an accuracy of 0.2- 0.5%, when weighing multi-component raw materials with different proportions at the same time, the materials can be weighed quickly and accurately, the process is convenient and fast, saving time and effort; the lower ends of multiple weighing devices are connected to collect The material is sent to the collecting device of the mixing mechanism
