Drafting trimming machine

Abstract

The invention provides a drafting trimmer and belongs to the field of processing machinery. The drafting trimmer comprises a cutting mechanism, a case, a material conveying tank, a recovery mechanism, a motor, a pre-tightening mechanism and a drafting mechanism, wherein the pre-tightening mechanism comprises a squeezing board, and the squeezing board and the material conveying tank are propped against the top surface and the bottom surface of a material respectively; the drafting mechanism comprises a drafting roller; the cutting mechanism is arranged between the drafting roller and the pre-tightening mechanism and comprises two work pieces, and the material is cut by the two work pieces during movement; the recovery mechanism is arranged bellow the drafting roller and comprises a recovery motor and a recovery roller, the motor drives the recovery roller, the material winds around the recovery roller after winding around the drafting roller, and the rotation speed of the drafting roller is smaller than that of the recovery roller; both the drafting roller and the recovery roller are driven by the motor. By the aid of the drafting roller and the squeezing board, the material located between the drafting roller and the squeezing board is in the tightened state instead of being in a bent state during cutting, and the cutting accuracy is improved.

Description

technical field [0001] The invention relates to the field of processing machinery, in particular to a drafting edge trimmer. Background technique [0002] Drafting is the process of regularly elongating and thinning fiber aggregates (such as sliver, roving, etc.) during spinning, and is the process of further loosening and gathering after carding. Bulk fiber raw materials are processed into fiber layers or slivers, and then become rovings and spun yarns, which must go through a gradual thinning process, so almost every major spinning machine or process has a drafting effect. [0003] In order to facilitate the collection of drawn materials, such as chemical fiber products, the chemical fiber products are usually processed into a size with a fixed width, so that the collected chemical fiber products are easy to roll. Therefore, an edge trimmer can be added before collection to process chemical fiber products into a specified width for easy collection. [0004] The inventor ...

AI Technical Summary

Problems solved by technology

[0004] The inventor found in the research that the edge cutting machine in the prior art cannot play an effective drafting effect when working, and because the chemical fiber product is a flexible material, the chemical fiber product cannot be fully unfolded under the condition of insufficient drafting, and it is easy to Make the actual width of the processed material larger than its trimmed width
