Through the mixing mechanism 5, the melt after secondary mixing is extruded and twisted in different thicknesses, which can break the uniform and regular structure of the melt, and form a staggered interlaced form in the conveying process, avoiding the local shear force concentration or deficiency caused by the uniform thickness of the melt during the subsequent three times of mixing. At the same time, the twisting process can further stir the residual micro-agglomerates or material layering in the melt, so that each region of the melt is fully contacted. This form can also make the melt more fully contact with the lower mixing roller, so that the shear effect of the three times of mixing is uniformly applied to each segment of the melt, reducing the dead angle of insufficient mixing, and providing a more powerful guarantee for the performance stability of the final product. The state of mixing can be observed through the observation port at the lower end of the mixing bin 1. When the lower end of the mixing mechanism 5 no longer extrudes the melt and there is no residual melt after secondary mixing on the rotating frame 31 at the lower end, the foot pedal at the rear end of the foot pedal connecting rod 9 is depressed, and the three times of mixing melt is scraped off from the front end of the mixing roller 32 by the scraping plate 8 and falls into the storage box at the upper end of the support 7, and then the next cycle of mixing is carried out. Through the mixing mechanism 3, the cutting mechanism 4 and the mixing mechanism 5, the whole process of automatic mixing is realized. From the initial mixing of the raw material conveying and the melt plasticizing to the cutting mechanism accurately cutting the S-shaped sheet, and then the mixing mechanism cutting the sheet into segments and pre-dispersing, each link does not need manual intervention for feeding, parameter adjustment or material sorting. This automatic mode completely avoids the uncertainty of manual operation, and does not need manual judgment of the mixing state, manual adjustment of the cutting size, and manual transfer of the melt, avoiding problems such as raw material addition deviation and cutting precision fluctuation caused by manual operation. The whole automatic process makes the processing conditions of each batch of materials highly uniform, the mixing degree of the melt, the cutting form and the pre-dispersing effect remain consistent, and finally the physical properties and appearance of the mixed product are stable, and there is no quality fluctuation between batches caused by manual operation difference, providing a stable raw material basis for subsequent production.
