Man-made lawn raw material mixing device

Abstract

The invention discloses a man-made lawn raw material mixing device comprising a weighting device, a raw material mixer and at least two storage silos. The material outlets of the storage silos are arranged above a material inlet of the weighting device, and a material outlet of the weighting device is arranged above the material inlet of the raw material mixer; the storage silos, the weighting device and the raw material mixer are arranged in a shell in sequence; and the material outlets of both the storage silos and the weighting device and the material inlets and the material outlets of the raw material mixer are respectively provided with a pneumatic valve. The invention controls raw material weighting, mixing, discharging, and the like through a computer, evenly mixes the raw material of a small quantity at low speed, weights the raw material at high precision, ensures the quality of a man-made lawn and saves the manpower and the electrical energy, and the like.

Description

Technical field: [0001] The invention relates to a mixing device for powdery and granular materials, in particular to a mixing device for main raw materials and various functional additive masterbatches in the artificial turf production process. technical background: [0002] With the rapid development of sports and other industries and the improvement of environmental protection requirements, artificial turf has been widely used in sports venues and leisure venues. The raw materials in the extrusion molding process of thermoplastic materials are mixed with pellets of various components, usually including main raw materials, color masterbatches, and various functional additive masterbatches. The main raw material is the base material that constitutes the artificial turf fiber, which accounts for the largest proportion; the color masterbatch plays a dyeing role, so that the artificial turf has various colors to meet the needs of customers, and the proportion is very small, an...

AI Technical Summary

Problems solved by technology

[0003] This mixing method has the following defects: the one, the weight of manual weighing is difficult to reach the specified requirements (accuracy is poor), if it does not meet the requirements, quality problems such as chromatic aberration of artificial grass fibers or poor local performance will occur, and at the same time It is difficult to avoid human misoperation (that is, there will be cases where the components of the material are wrongly weighed during the weighing process)

Second, the existing manual weighing method has low work efficiency

The 3rd, existing mixing method, owing to adopt high-power electric motor to carry out high-speed mixing (every batch mixes about 100 kilograms of materials), not only waste power supply, and in the high-mixing process because the powder that raw material particle surface peels off is more, to On-site cleaning and extruder motor maintenance requirements are high

At the same time, due to the long stirring time of the high-mixing process, the static electricity formed on the surface of the particles is relatively large, and it is easy to form a single material adsorbed on the wall of the silo during the feeding process, resulting in intermittent color difference

Also, due to the inconsistency of the specific gravity of the raw materials, the color difference will be caused by the sedimentation of the original mixed material and colored masterbatch (heavy specific gravity).
