PVC pipe fitting full-automatic weighing and mixing and powder conveying and supplying system

Abstract

The invention discloses a PVC pipe fitting full-automatic weighing and mixing and powder conveying and supplying system. Bin top dust collectors are arranged at the upper portion of a PVC raw materialbin and a CaCo3 raw material bin, the PVC raw material bin top dust collector and the CaCo3 raw material bin top dust collector are connected with a main dust collector, a discharge port at the bottom of the PVC raw material bin is connected with a weighing material hopper at the rear portion through a pipeline, a Roots vacuum pump is arranged on a pipeline at the front end of an inlet of the weighing material hopper, a high-speed mixer is arranged on the lower side of the weighing material hopper, the materials in the weighing material hopper can enter the high-speed mixer through a pipeline, a cooling mixer is arranged on the lower side of the high-speed mixer, a material mixing unit platform is arranged on the lower side of the cooling mixer, the materials in the cooling mixer can fallinto a transition material hopper on the lower side, and the transition material hopper is connected with a mixing material bin. In actual use, weight errors in manual weighing and raw material wastein the feeding process can be effectively avoided through the system, the product quality can be improved, and the whole system is easy to operate and convenient to use.

Description

technical field [0001] The invention relates to the technical field of plastic production equipment, in particular to a PVC pipe automatic weighing and mixing and powder conveying and feeding system. Background technique [0002] At present, in the domestic PVC pipe production process, in order to ensure that the injection-molded plastic parts can achieve the expected physical and chemical properties, the weighing ratio of the raw materials of different components must be strictly controlled according to the production process, so the raw materials should be weighed before mixing. Raw materials and raw materials are added by weighing and measuring manually with a platform scale, and manually added to the high-mixer mixing process. Due to the use of manual weighing, this feeding method will be measured in the long-term production process due to human operation. Errors, incorrect weights, waste often occur during feeding and feeding, and the weight ratio of each component does...

AI Technical Summary

Problems solved by technology

[0003] The present invention solves the problems in the prior art that the ingredients of raw materials and auxiliary materials are added by manual weighing and measurement with platform scales, and then manually added into the mixing process of the high-mixer. Due to the open environment and manual operation, there will be large dust in the working environment, measurement errors, incorrect weights, and wastes often occur in the process of feeding and feeding. Provide a PVC pipe automatic weighing and mixing and powder Body conveying and feeding system, when it is applied, the material is conveyed to the weighing hopper through the Roots vacuum pump, and a certain amount of raw material is weighed according to the process requirements, and then the raw material is put into the mixing unit platform for complete mixing and then sent to the follow-up Section for further production and processing
