Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when the stirring shaft rotates and the stirring fins stir the slices, the slices near the stirring fins will be squeezed by the stirring fins, thereby driving the slices to turn continuously in the cylinder, and at this time the slices It will become soft after being heated, and the adjacent slices may stick after being pressed, which will affect the product quality

Abstract

The invention relates to the technical field of chip pre-crystallization equipment, and relates to a polyester chip pre-crystallization system. The polyester chip pre-crystallization system comprisesa crystallization box, a feeding pipe arranged at one end of the crystallization box and a discharging pipe arranged on the lower side of the other end of the crystallization box, and a feeding deviceis arranged in the crystallization box. The polyester chip pre-crystallization system is characterized in that the feeding device comprises a rack arranged in the crystallization box and a conveyer belt which is arranged on the rack and does annular motion, guide rolls are rotatably connected to the two sides of the rack correspondingly, the guide rolls on the two sides are obliquely and downwards arranged towards the sides close to each other, the two sides of the conveyer belt abut against the guide rolls on the two sides to be cocked upwards, and a hot air device used for blowing chips isarranged over the conveyer belt. The polyester chip pre-crystallization system has the following effects that the chips are dried by hot air through clearances among the chips when the chips are turned over, the extrusion force among the chips is small, therefore, the possibility that the chips are adhered after being pressed is reduced, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of chip pre-crystallization equipment, in particular to a polyester chip pre-crystallization system. Background technique [0002] In the melt spinning production process of polyester chemical fiber, in order to avoid the problems of polymer degradation, polymer macromolecule breakage, high spinning breakage rate, and low strength of finished products caused by polyester chips containing water during high temperature melting, The moisture content in the chips must be reduced before spinning, so pre-crystallization of polyester chips is necessary. [0003] The Chinese utility model patent with the authorized announcement number CN2540269Y discloses a low-melting point polyester chip pre-crystallization device, including a cylinder, a motor, a reducer and a conical head; the output shaft of the motor is connected to the input shaft of the reducer, The motor and reducer are supported on the flat cover of the c...
