Description

Technical Field

[0001] The present application relates to the technical field of mixers, and more specifically, to a PET low-melting-point chip mixer. Background Art

[0002] PET chips refer to flakes or sheets made of polyethylene terephthalate (PET). PET is a common plastic material with excellent physical and chemical properties, and is widely used in the manufacture of bottles, containers, fibers, films and other applications. PET chips can have different thicknesses, sizes and shapes, and can be customized according to specific needs. PET chips usually have the characteristics of high transparency, high strength and good heat resistance, so they are widely used in packaging, printing, advertising, electronics, construction and other fields.

[0003] When producing PETG slices, it is indeed necessary to mix the masterbatch (i.e. PET particles) with auxiliary materials (such as plasticizers, pigments, etc.). PET particles and auxiliary materials may have different surface adhesions. Some auxiliary materials have higher adhesion and are easy to adhere to the inner wall of the mixer. If they are not cleaned after a long period of accumulation, a layer of difficult-to-clean material will remain on the inner wall of the mixing chamber, which will make cleaning more difficult and require more manpower and material resources.

[0035] The arrangement of the block 16 and the slot 17 facilitates the disassembly and replacement of the soft scraper 15 . When the soft scraper 15 needs to be cleaned, the block 16 at the bottom of the support plate 14 is pulled out from the slot 17 . After cleaning, the block 16 is inserted into the slot 17 .

[0036] Reference Figure 2-Figure 3 A feed inlet 3 is provided at the top of the mixer 1, and a stirring assembly is provided inside the mixer 1.

[0037] When the masterbatch and the auxiliary material need to be mixed, the fixed section 7 is driven to rotate by the motor 12, and the rotation of the fixed section 7 drives the multiple connecting rods 8 on the outer wall of the telescopic section 6 to rotate. When the connecting rods 8 rotate, they will slide inside the annular track 5, and will drive the telescopic section 6 to extend and retract in the fixed section 7. At this time, the connecting rods 8 and the stirring plate 9 can move up and down while rotating, so that the mixed material can be stirred and dispersed more evenly during the mixing process.

[0040] Working principle: When the masterbatch and the auxiliary material need to be mixed, the fixed section 7 is driven to rotate by the motor 12, and the rotation of the fixed section 7 drives the multiple connecting rods 8 on the outer wall of the telescopic section 6 to rotate. When the connecting rods 8 rotate, they will slide inside the annular track 5, and will drive the telescopic section 6 to extend and retract in the fixed section 7. At this time, the connecting rods 8 and the stirring plates 9 can move up and down while rotating. At this time, the fixed plate 11 on the outer wall of the fixed section 7 will also rotate.
