Automatic polyurethane color-matching stirring processing system and method

Abstract

The invention relates to an automatic polyurethane color-matching stirring processing system and method. The method comprises the following steps: (1) taking out a charging basket from an oven, placing the charging basket on a lifting device, and lifting the charging basket to the top; (2) pushing the charging basket to a feeding station with a push cylinder on the upper portion of a rack, and pressing downwards a tapper at the upper end of the feeding station for vertically penetrating through the charging basket from the center position; (3) repeating the steps (1) and (2), flattening the charging basket and sending out the flattened charging basket; (4) making raw materials flow into corresponding stirring tanks through guide pipes at the lower end of a hopper, wherein color paste barrels, catalyst barrels and water tanks are also connected to the stirring tanks through the guide pipes; (5) after main materials and auxiliary materials are injected into the stirring tanks, starting to rotate stirring rods, so that the materials in the stirring tanks are completely and uniformly mixed; and (6) outputting the stirred materials, and injecting the materials into storage tanks or directly feeding the materials into next corresponding processing equipment through a feeding pump connecting pipeline. According to the method, the full-automatic stirring preparation process is achieved, the feeding proportion accuracy is high, no raw material is left in a raw material barrel, and cost waste caused by raw material waste is effectively reduced.

Description

technical field [0001] The invention belongs to the field of mechanical equipment and relates to automatic shoe-making equipment, in particular to a system and method for automatic color matching and mixing of polyurethane. Background technique [0002] In the shoe-making industry, shoe soles are usually made by mixing polyurethane A and polyurethane B in proportion. During the preparation, it is first necessary to preheat polyurethane A and then add color paste, antistatic agent, catalyst, etc. according to the proportion. The ingredients are evenly stirred, and then mixed with the polyurethane B material to make the shoe sole material. At present, the more common method is to put the raw material bucket into the oven and bake it to the set temperature, then the worker takes out the baked material bucket from the oven, uses a hand-held tool to manually open the lid, and then through the opening of the lid, Sequentially inject and weigh various ingredients such as lustrous ...

AI Technical Summary

Problems solved by technology

In this process, it mainly relies on the manual operation of workers, with a large workload and high labor intensity; workers need to repeatedly weigh and add various ingredients, and it is difficult to ensure accurate proportioning of each bucket of materials; spills are inevitable during the operation process. Sticky, the working environment on site is messy; the viscosity of the raw materials after filling the color paste becomes higher, causing the raw materials to stick to the wall inside the barrel, making it difficult to dump cleanly. A large number of barrels are used as production waste, polluting the environment and difficult to handle
