Drawing slenderizing device for human hair fiber bundles

Abstract

The invention discloses a drawing slenderizing device for human hair fiber bundles, which mainly comprises a frame, guide rails, sliding blocks, clamping heads, a driving part, a holding self-locking auxiliary mechanism, a release pressure rod auxiliary mechanism and the like. The drawing slenderizing device is characterized in that at least two groups of closed annular guide rails are mounted on the frame, each closed annular guide rail is formed by enabling sectional guide rails to be adjacent or connected end to end, a plurality of sliding blocks are mounted on the guide rails and can move along the guide rails, one clamping head is mounted on each sliding block, and the clamping heads can sequentially hold, draw and release the human hair fiber bundles under the action of the auxiliary mechanisms during when moving together with the sliding blocks. The rolling wheel type contact is adopted between the sliding blocks and the guide rails; the human hair fiber bundles are held in grooves on the clamping heads by utilizing pressure rods hinged with one end of each clamping head by virtue of a cylinder or a counterweight for exerting pressure, and the pressure rods are locked by self-locking cams or pawls which are in contact with the pressure rods; and the release pressure rod auxiliary mechanism is used for reliving the self-locking of the pressure rods and releasing the held human hair fiber bundles.

Description

technical field [0001] The invention relates to a long fiber stretching and thinning device, in particular to a human hair fiber bundle stretching and thinning device, which can stretch and thin the human hair fiber bundle without twisting. Background technique [0002] Drawing and thinning technology is a method that combines physical and chemical processing to thin and shape the fibers in the fiber strip. At present, the most common method is wool drawing. The current stretching and thinning technology is generally to add a certain twist to the top and then stretch it to increase the cohesion between fibers. Due to the poor cohesion of human hair, it is not suitable to use the current stretching and thinning technology for stretching. Stretching, especially when the stretched human hair is used to make wigs, the current stretch thinning technology is not applicable, because the twisted stretched human hair will leave permanent bends and twists.
