Plastic particle and color master batch equal-ratio feeding equipment

Abstract

The invention relates to the field of bottle cap machining, in particular to plastic particle and color master batch equal-ratio feeding equipment which comprises a screw extruder fixedly mounted on the ground and further comprises a linear pushing mechanism, a capacity adjusting mechanism, a rotating table, a pushing and lifting mechanism, a first elastic gate, a second elastic gate, an electric gate, a particle box, a color master batch box, a bottom frame, a particle feeding box, a color master batch feeding box, two swing dust collection mechanisms, a transmission mechanism and a limiting abutting mechanism. According to the plastic particle and color master batch equal-ratio feeding equipment, through the combination of the pushing and lifting mechanism and the transmission mechanism, when the linear pushing mechanism forwards pushes, a conical air suction hard pipe is driven to incline upwards, then particles just falling from the particle feeding box and the color master batch feeding box are cleaned, compared with the mode that the particles fall into a conical stirring box to be sucked, the suction range is larger, the situation that dust is just sucked by a certain distance, particles falling from the upper side bury the sucked dust is avoided, and the cleaning effect is remarkably improved.

Description

technical field [0001] The invention relates to the field of bottle cap processing, in particular to an equal-ratio feeding device for plastic particles and color masterbatches. Background technique [0002] Color masterbatch is the dyeing agent needed in the production of plastic bottle caps, and the color ratio of plastic particles and color masterbatch determines the color of the bottle cap when it is produced. Usually, workers mix and stir, and then the stirring is carried out by an inhaler. The final particles are inhaled into the screw extruder for processing. Because the ratio of the inhaled plastic particles and the color masterbatch after mixing is difficult to control, there is a color difference between each bottle cap. When the color difference is serious, this batch of bottle caps Scrapping is required, which wastes a lot of resources and consumes a lot of time for workers to mix. [0003] my country's patent application number: CN201520583916.4; discloses a pl...

AI Technical Summary

Problems solved by technology

[0005] 1. Although this solution can mix plastic particles and color masterbatch evenly, it is still difficult to control the ratio of mixed plastic particles and color masterbatch when feeding

[0006] 2. This solution cannot clean the dust in the plastic particles and masterbatch, so that there are a large number of defective products in the processed bottle caps. Even if it is cleaned, the workers use a vacuum cleaner to clean the dust on the particles before mixing. The dust is sucked and cleaned, the cleaning effect is not good, and the cleaning time is long

[0007] 3. The mixed plastic particles and color masterbatch are sucked through the suction mechanism. After a period of time, workers need to change the insertion position of the suction head, which wastes a lot of time for workers
