Description

Technical Field

[0001] This utility model relates to the technical field of plastic machinery and engineering, and in particular to a feeding device for blending PBT chips and adhesive emulsion. Background Technology

[0002] In the modification process, PBT (polybutylene terephthalate) materials often need to be blended with adhesive emulsions to improve their interfacial bonding with additives such as flame retardants and glass fibers, thereby obtaining high-performance composite materials. The uniformity and stability of this blending process directly determine the quality of the final modified plastic product.

[0003] In existing technologies, mixing devices for PBT modification are mostly designed for solid dry mixtures. For example, Chinese utility model patent CN217189540U discloses a feeding and mixing device for modifying PBT flame-retardant plastics. This device, by incorporating a vertically movable pulverizer and a rotating scraper, effectively improves the mixing efficiency of solid flame-retardant plastics and reduces residue in the container, thus possessing certain advantages.

[0004] However, when such devices are applied to solid-liquid blending scenarios involving PBT chips and adhesive emulsions, significant drawbacks are exposed, particularly the difficulty in cleaning: Material Residue and Cross-Contamination: The adhesive emulsion is viscous and, after being blended with PBT chips, easily adheres to the inner wall of the mixing tank, the agitator blades, and the discharge mechanism. Existing equipment has a complex internal structure (e.g., reciprocating troughs, chutes, linkage mechanisms), creating numerous cleaning dead zones where residual material is difficult to remove completely. This not only wastes raw materials but also leads to serious cross-contamination when changing product formulations.

[0005] The cleaning process is difficult and inefficient, relying mainly on manual disassembly and cleaning. This process is not only time-consuming and labor-intensive, extending equipment downtime, but also subject to subjectivity, making it difficult to guarantee cleaning effectiveness and affecting the consistency between production batches.

[0006] Impact on subsequent production and product quality: Residual materials that are not thoroughly cleaned accumulate in the equipment over a long period, which may cross-link, solidify, or degrade, forming hard scale. These contaminants may detach and mix into new products during subsequent production, leading to quality problems such as black spots and reduced strength. Utility Model Content

The cleaning unit, mounted on the base plate, is used to clean the mixing drum, mixing assembly, and feeding assembly. During use, PBT chips and adhesive emulsion are placed inside the mixing drum, and the mixing assembly is activated to blend the PBT chips and adhesive emulsion into a mixture. After mixing, the discharge valve is opened, allowing the mixture to flow through the discharge pipe into the feeding assembly for feeding.

At the same time, water enters the inside of the shell through the second conveying pipe to clean the rotating spiral blades, thereby improving cleaning efficiency and convenience.

[0012] Preferably, the system also includes a drain pipe and a drain valve. A drain pipe is provided at the bottom of the housing, and a drain valve is provided on the drain pipe.
