Detailed Description

The following describes the present design in detail with reference to the accompanying drawings.

One as shown in fig. 1, a fibre silk device of hanking for carbon fiber production, the structure is including dividing the silk sieve 1, depression bar device 2 and bracket 3, divide silk sieve 1 to have the rectangular shape sieve mesh 102 of a plurality of vertical in succession, depression bar device 2 is the rectangle framework that two cylinder steel pipes connect into through two end plates, bracket 3 is symmetrical structure, bracket base 7 including the symmetry, pole setting 8 and violently support 5, two end plates 203 of depression bar device 2 pass through bolt and two one end fixed connection that violently support 5, divide the both ends of silk sieve 1 and two other ends that violently support 5 to pass through bolt fixed connection, can dismantle.

Wherein, divide filament sieve 1's every rectangular shape sieve pore 102 all to be equipped with and separate the fender, and two adjacent sieve pores 102 separate fender 103 and separate and keep off 104 dislocation set from top to bottom, sieve pore 102 surface is smooth wear-resisting, does not hinder the cellosilk. The number of the screen holes 102 on the wire separating screen 1 is reasonably set according to the number of the fiber wires required by actual production, and the wire separating screen 1 is used for twisting and plays a wire separating role as a component of a twisting device.

The distance between two cylindrical steel pipes of the pressure lever device 2 is 20-40 cm, the two cylindrical steel pipes are an upper pressure lever 201 and a lower pressure lever 202 of the pressure lever device respectively, and when the two cylindrical steel pipes are twisted, the pressure lever device 2 can be turned over by adjusting the tightness of bolts connecting the two end plates 203 and the transverse support 5, the surface of the pressure lever device 2 is smooth and wear-resistant, and the fiber yarns are not damaged.

The upright posts 8 are designed to be in section sleeve joint and locking, the height can be adjusted in real time according to the requirement of the wire separating screen 1, and the upright posts 8 which are symmetrical on two sides are fixedly connected through the connecting rods 4; the transverse support 5 is welded with the top of the upright post 8, and the bottom of the upright post 8 is welded with the bracket base 7; the bracket base 7 is fixed on the ground through the foundation bolts, so that the whole twisting device does not swing when the bracket 3 is stable and twisted, and the position of the bracket can be flexibly changed through loosening the foundation bolts.

Wherein, violently hold in the palm 5 for the rectangle steel sheet, its both ends are equipped with the connecting hole 6 that is used for fixed branch silk sieve 1 and depression bar device 2, and its length can adjust as required.

Examples

When the twisting device is used, the twisting device is placed in front of the comb guide rollers of a production line, the fiber yarns pass through the screen holes 102 on the yarn passing screen 1 to determine the position sequence, then pass through the space between the upper pressure rod 201 and the lower pressure rod 202, and then enter the comb guide rollers. When the twisting is needed, firstly, the fastening bolt is loosened so that the pressure lever device 2 can be turned over, then the upper pressure lever 201 is pressed downwards on the side of the wire separating screen 1, as the upper separation baffle 103 and the lower separation baffle 104 of two adjacent screen holes 102 on the wire separating screen 1 are staggered, all the fiber yarns naturally form a transverse V-shaped layered opening structure with an opening facing the wire separating screen, a threading needle tied with a carbon fiber rope can quickly penetrate from one end to the other end between two layers of opening gaps, then the pressure lever device 2 is turned over reversely, the lower pressure lever 202 is lifted upwards on the side of the wire separating screen 1, a transverse V-shaped layered opening structure with an opening facing the wire separating screen 1 is naturally formed again, the threading needle quickly penetrates from one end to the starting end between two layers of opening gaps, and then is tied together with the carbon fiber rope at the starting end, and the twisting process of the fiber yarns is completed.

Therefore, each fiber wire is fixed in a plurality of holes in the infinity shape formed by the reciprocating of the carbon fiber ropes, and the position sequence of the fiber wires is ensured not to be changed in the running process. When the filament collecting machine is operated, the carbon fiber rope is unwound, and then the filaments are sequentially wound on each filament collecting machine station, so that the filaments of each filament collecting machine station correspond to the protofilaments, the traceability of a product is guaranteed, and meanwhile, the phenomena of mutual winding and breakage of adjacent filaments, friction damage and the like are avoided.
