Description

TECHNICAL FIELD

[0001] The utility model relates to textile equipment technical field especially a feeding device with buffer effect. BACKGROUND

[0002] With the continuous development of chemical fiber industry, the demand of chemical fiber is increasing, and the requirement of product quality is also rising. The forming of ultrafine denier nylon 6 generally adopts chip spinning. The polymer melt is made into spinning chip through casting belt, granulation and other processes, and then the chip is put into the stock bin and into the spinning machine to be remelted into melt and spun. The process is very important when producing yarn, but the product quality is not only determined by spinning winding, and the feeding link is also very important.

[0003] The existing feeding device has a relatively simple structure, and the feeding port has a large drop from the bottom of the stock bin. Due to the large number of chips, the chips will be affected by gravity during feeding, generating a large vertical impact force, which will impact the screw extruder connected to the bottom of the stock bin, causing the melt pressure and flow to fluctuate, thereby affecting the production and product quality. SUMMARY

[0004] The utility model solves the technical problem, provides a kind of ultrafine denier nylon 6 spinning feeding device with simple structure, which can directly avoid the vertical impact of chip on the bottom of stock bin and screw extruder, and can improve product quality.

[0005] The utility model is implemented as follows: a kind of ultrafine denier nylon 6 spinning feeding device, including

[0006] A stock bin has a feeding port at the top and a discharge port at the bottom, and the feeding port and the discharge port are in the form of a neck;

[0007] A buffer device is arranged in the stock bin and located below the feeding port, which includes a buffer piece and a plurality of fixing rods, the buffer piece is in the form of a tapered structure with a small upper part and a large lower part, the side wall of the buffer piece is provided with a plurality of through holes, one end of the fixing rod is fixed to the lower end of the buffer piece, and the other end is fixed to the inner side wall of the stock bin.

[0008] Further, the diameter of the large end of the buffer piece is greater than the diameter of the feeding port and the discharge port.

[0009] Further, the number of fixing rods is four, which are evenly distributed at the lower end of the buffer piece.

[0010] The utility model discloses a kind of advantages, which is characterized in that a buffer device is added in the silo, and the slices can slide along the side of the silo through the buffer device. On the one hand, the vertical impact force caused by the slices on the bottom of the silo and the screw extruder is directly avoided, and on the other hand, the gravity of the slices is dispersed. Due to the influence of side friction resistance, the impact force generated by the slices during feeding is significantly dispersed, and the direct external force influence on the screw extruder is solved, which promotes the improvement of product quality from the raw material end.
