Embodiment Construction

[0009] As shown in Figures 1 and 2, the carbon fiber drafting machine of the present invention includes two drafting units 1, and the two drafting units 1 are respectively arranged on both sides of a pre-oxidation furnace 3 with a multilayer heating channel 2; A drafting unit 1 includes multiple groups of drafting rollers 4 arranged from bottom to top, each group of drafting rollers 4 has its own independent driving device, each group of drafting rollers 4 and the multi-layer heating channel of the pre-oxidation furnace 3 2 correspondingly, so that the carbon fibers can pass through each group of pulling rollers 4 in sequence and reciprocate through the heating channels 2 of each layer layer by layer.

[0010] A plurality of steel wire traction rollers 5 are also arranged on the drafting unit 1, the positions of the steel wire traction rollers 5 correspond to the heating channels 2 of each layer of the pre-oxidation furnace 3, and a traction steel wire 6 reciprocates around the...

Abstract

The invention relates to production equipment for carbon fiber, in particular to a carbon fiber drafter. The drafter comprises two drafting units which are respectively arranged at two sides of a preoxidation furnace with multiple layers of heating channels; each drafting unit comprises multiple groups of drafting rollers which are distributed from down to up, each group of drafting rollers corresponds to the multiple layers of heating channels of the preoxidation furnace, and the carbon fiber can pass through the layers of heating channels one by one in reciprocation through the groups of drafting rollers sequentially. The drafter can ensure the carbon fiber to pass through the multiple layers of heating channels of the preoxidation furnace one by one in reciprocation, make full use of vertical space of the equipment and greatly reduce the length and occupying area of the production line; as each drafting roller group has a separate driving device, the rotational speed of the drafting roller group can be regulated by frequency conversion according to tension requirement of the process and center-controlled by a computer, thus improving the processing effect of the carbon fiber.

Description

technical field [0001] The invention relates to a carbon fiber production equipment, in particular to a carbon fiber drafting machine. Background technique [0002] In the process of carbon fiber production, it is necessary to pre-oxidize the carbon fiber by heating. The usual production equipment is to set a drafting mechanism on both sides of the pre-oxidation furnace. through to complete the pre-oxidation process. Existing carbon fiber drafting devices are usually provided with a group of drafting rollers on both sides of a pre-oxidation furnace with a single-layer heating channel. Such a structure makes the entire production line longer and the equipment occupies a larger area. In addition, the The tension of carbon fiber is also not easy to be well controlled, which affects the final processing effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a carbon fiber drafting machine with small footprint, goo...
