Abstract

The utility model relates to a drafting machine which comprises a yarn feed wheel, heat rollers and a discharge roll, wherein at least two heat rollers are provided, and are respectively arranged between the yarn feed wheel and the discharge roll. The drafting machine comprises two heat rollers, namely an upper heat roller and a lower heat roller, which are arranged between the yarn feed wheel and the discharge roll. As the number of the heat rollers is increased, higher brute force can be provided during the process of the fiber yarn spinning, the twist number of fiber yarn obtained through the primary processing can be improved, the strength of the fiber yarn is improved, and the rate of elongation at rupture is reduced.

Drawing machine

Technical field

The utility model relates to a kind of drafting machine, especially refers to a kind of drafting machine for improving spinning fibre intensity and high twist after the process improvement.

Background technology

Drawing machine is a kind of equipment of the various silvalins that are used to stretch and weave, this equipment has generally included yarn feeding wheel, heat dish and filament-extruding disc, with polypropylene fibre as-spun fibre process yarn feeding wheel, behind heat dish and the filament-extruding disc, be involved in steel ingot again and form general polypropylene staple fibre spun yarn, in existing drawing machine, because the heat dish often can not provide enough pretightning forces, therefore often twisting count is lower for spun polypropylene staple fibre spun yarn, if will obtain the more yarn of high twist, often need to carry out secondary operations, cause cost to raise, simultaneously, the intensity of the polypropylene staple fibre spun yarn that spins out is less, and fracture elongation is higher, causes the yarn availability of making of polypropylene staple fibre spun yarn to descend.

The utility model content

Technical purpose of the present utility model is in order to provide a plurality of heat dishes of a kind of employing to come wrapping wire, to provide bigger pretightning force to produce the drawing machine of the higher polypropylene fibre line of intensity.

Drafting machine bag Yarn feeding wheel of the present utility model, at least two heat dish and filament-extruding disc, this heat dish of at least two is distributed between Yarn feeding wheel and the filament-extruding disc successively.

The heat dish of this drawing machine is two, and these two heat dishes are respectively heat dish and following heat dish, and heat dish and following heat dish are distributed between yarn feeding wheel and the filament-extruding disc on this.

Beneficial effect: drawing machine of the present utility model is owing to increased the quantity of hot dish, therefore in the process of spinning fibre yarn, can provide higher pretightning force, thereby the twist of the silvalin that the raising time processing obtains, and the intensity of raising silvalin reduce fracture elongation.

For ease of explanation detailed content and the technology relevant with the utility model, below hereby just cooperate accompanying drawing to describe.

Description of drawings

Fig. 1, be the schematic diagram of this in the past drafting machine coiling;

Fig. 2, schematic diagram for winding the line in the drawing machine of the utility model embodiment.

The specific embodiment

Please refer to illustrated in figures 1 and 2, Yarn feeding wheel in difference hauling machine prior art and the present embodiment technology, the schematic diagram that heat dish and filament-extruding disc arrange, in common drafting machine, comprised respectively a Yarn feeding wheel 1,2 and filament-extruding discs 4 of a heat dish, silvalin by from the steel ingot conjunction 5 that is wound with silvalin after Travellers conjunction 6 is emitted, successively with filament-extruding disc 4, send after heat dish 2 and Yarn feeding wheel twine and carry out coiling, but in order to be increased in the tension force between the silvalin in the spinning fibre yarn process, the utility model has adopted the mode that increases drafting machine medium heat disk 2 numbers, namely be provided with at least a plurality of heat dishes, these a plurality of heat dishes are arranged between Yarn feeding wheel 1 and the filament-extruding disc 4, so that this drafting machine has higher fibre tension in the coiling process, in present embodiment, be limited to the restriction of structure, and the needs of controlling cost, the number of set heat dish is two among this embodiment, this heat dish of two is respectively heat dish 2 and lower heat dish 3, upward heat dish 2 and lower heat dish 3 are arranged between Yarn feeding wheel 1 and the filament-extruding disc 4, after silvalin is emitted from the steel design part 5 that is wound with silvalin, successively with filament-extruding disc 4, lower heat dish 3, send after upper heat dish 2 and Yarn feeding wheel 1 twine and carry out coiling, coiling goes out to have more high twist and the more silvalin of hightension.

Claims

1, a kind of drafting machine comprises Yarn feeding wheel, heat dish and filament-extruding disc, and it is characterized in that: the heat dish in this drafting machine comprises at least two, and this heat dish of at least two is distributed between Yarn feeding wheel and the filament-extruding disc successively.

2, drafting machine according to claim 1 is characterized in that: the heat dish of this drafting machine is two, and these two heat dishes are respectively heat dish and lower heat dish, and heat dish and lower heat dish are distributed between Yarn feeding wheel and the filament-extruding disc on this.
