A kind of tow crimping and drying system

Abstract

The present invention relates to the spinning field, and especially relates to a tow crimping and drying system. The system comprises a reeling machine, a tow conveying device and a drying oven; the tow conveying device comprises an adjusting bin, a double conveying belt mechanism and a swinging silk-evening mechanism; the double conveying bet mechanism comprises a rack, an upper conveying belt, a lower conveying belt and a first drive motor; the upper conveying belt and the lower conveying belt are arranged in parallel, a conveying passage is formed between the upper conveying belt and the lower conveying belt, an entrance of the conveying passage is connected with an exit of the adjusting bin; and the swinging silk-evening mechanism comprises a material swinging bin, a central positioning rod, a second drive motor, a rotary disc, an eccentric rod and a swing rod, wherein the rotary disc is connected with the second drive motor, the eccentric rod is arranged in an eccentric manner on the rotary disc, one end of the swing rod is hinged to the eccentric rod while the other end is hinged onto the material swinging bin, and an exit of the material swinging bin is connected with a chain plate of the drying oven. With adoption of the system, drying and molding of tows become even, and stability of products is ensured.

Description

technical field [0001] The invention relates to the spinning field, in particular to a tow crimping and drying system. Background technique [0002] In the chemical fiber industry, PET is generally used as the raw material for staple fibers. After the whole bottle is crushed and cleaned, it is melt-spun, then drawn, crimped, heated and shaped in an oven, and then cut into shape. Among them, between the crimping and the oven, because the equipment between the two does not match, because the coiler is fast and the exit is narrow, while the oven is slow and the entrance is wide, so a connecting device needs to be installed in the middle. We have designed a new connection device. [0003] Now common practice such as figure 1 As shown, after the tow is crimped by the crimping machine 1, it comes out through the silk outlet 2, and then enters a flat swing plate mechanism, which uses one end as the swing center 3, and a set of swing rod mechanism 5 is arranged on the other side, ...

Problems solved by technology

Again, because the crimped tow is relatively fluffy, the tow layer will be thicker after reaching the oven chain plate, which will cause uneven heating of the inner and outer tows
