Abstract

The invention discloses a roving frame draft gear applicable to high draft. The roving frame draft gear comprises a cradle. A front leather roller and a second leather roller are sequentially arranged on the lower side of the cradle via a leather roller clamp leg, a corresponding front roller is arranged below the front leather roller, a second roller is arranged below the second leather roller, a third leather apron and a rear leather apron are arranged at the rear of the second leather roller, an upper lather roller and an upper pin are respectively arranged in the third leather apron and the rear leather apron, and the upper leather roller is connected with the cradle by the leather apron clamp leg; a corresponding third roller leather apron is arranged below the third leather apron, a rear roller leather apron is correspondingly arranged below the rear leather apron, and lower pins and lower leather rollers are respectively arranged in the third roller leather apron and the rear roller leather apron; roller slide seats are respectively arranged below the rear roller leather apron and the third roller leather apron, rolling shafts are arranged in the roller slide seats, and the lower leather rollers are respectively connected with the rolling shafts. The roving framer draft gear has the advantages that the roving frame draft gear is simple in structure, stable and reliable in operation and high in roving production draft multiple, and the production cost can be lowered for enterprises.

Description

Technical field: [0001] The invention relates to textile machinery, in particular to a roving frame traction device suitable for large draft. Background technique: [0002] In order to achieve energy saving, emission reduction, and cost reduction goals, textile mills fully tap the potential of pre-spinning equipment to increase unit yield. It is necessary to reduce the total number of equipment to achieve the above goals, and one of the ways to increase the yield per unit is to increase the quantity of semi-finished products, which requires related equipment to be able to adapt to this heavy quantitative drafting, that is, to have a large drafting multiple; and The existing FA491 type roving frame used to have a top roller nip at the end, which is unfavorable for fiber control, not suitable for spinning heavy and quantitative sliver, and cannot realize the improvement of unit yield. Invention content: [0003] The technical problem to be solved by the present invention is...
