Problems solved by technology

[0002] In recent years, due to the needs of the section color spinning process, people start from the drawing frame process, design and innovate the section color drawing frame, develop and produce section color cotton (wool) strips; the conventional drawing frame, the roller or section of the drafting mechanism The color and color matching rollers are all integral structures. In order to incorporate the colored fiber strips in intervals and unequal amounts in the cotton (wool) sliver, on the existing segmental color drawing frame, a

Embodiment 1

[0024] Such as figure 1 and figure 2 As shown, the coaxial combined roller 1 of this example adopts a four-roller four-control structure, including a roller 11, a roller 12, a roller 13, a roller 14, a toothed wheel 15, a toothed wheel 16, a toothed wheel 17 and a toothed wheel 18.

[0025] Roller 12 shaft end fixed toothed wheel 15, roller 11 is movable sleeved on the shaft, roller 13 shaft end fixed toothed wheel 18, roller 14 is movable sleeved on the shaft, the sleeve end of roller 11 is fixed toothed wheel 16, roller 14 The fixed toothed wheel 17 at the sleeve end, and a whole set of combined rollers is fixed on the wallboard support by bearings and supports 19.

[0026] The four sets of linear density characteristics are respectively T 1 , T 2 , T 3 and T 4 The fiber strips are fed into the roller 11, roller 12, roller 13 and roller 14 in the coaxial combined roller 1 respectively. Roller 11, roller 12, roller 13, roller 14 are driven by toothed wheel 16, toothed ...

Embodiment 2

[0028] Such as Figure 5 As shown, the coaxial combined roller 1 in this example adopts two rollers and two control structures, and after multi-points are applied to the drafting mechanism of the draw frame, the linear density is respectively T 1 , T 2 The fiber strips are fed into the corresponding rollers 11 and 12 of the first pair of coaxial combined rollers through the guide grid or the bell mouth, respectively, and the linear density is T 3 , T 4 The fiber strips are fed into the corresponding rollers 3 and 4 of the second pair of coaxial combined rollers respectively through the guide grid or the bell mouth, and the linear densities are respectively T 5 , T 6 The fiber strips are fed to the corresponding rollers 5 and 6 in the third pair of coaxial combined rollers through the guide bar grid or bell mouth, and so on. The segmental setting of the speed of each roller, in the i-th and i+1 process segments, corresponds to the special number T of each roller in each pai...

Abstract

A method for drawing colored cotton or colored wool with equal linear density, through segmental, synchronous, and equal speed coupling control methods, using a computer program controller to control the speed of coaxial combined rollers, which can be very easy to program the process , to achieve the same amount of sliver or woolen sliver fed at any time, and different feeding ratios in different periods, to achieve different colors and irregular combinations in the cross-section and length direction, and to maintain sliver or woolen sliver evenness of dryness.

Description

technical field [0001] The invention relates to a yarn forming method and device, in particular to a method and device for drawing colored cotton or wool with equal linear density segments. Background technique [0002] In recent years, due to the needs of the section color spinning process, people start from the drawing frame process, design and innovate the section color drawing frame, develop and produce section color cotton (wool) strips; the conventional drawing frame, the roller or section of the drafting mechanism The color and color matching rollers are all integral structures. In order to incorporate the colored fiber strips in intervals and unequal amounts in the cotton (wool) sliver, on the existing segmental color drawing frame, a group of cotton (wool) sliver For the base strip, on the longitudinal path of the base strip, set color strip feeding rollers at multiple points, use a program controller that can be programmed in sections to control the stepping motors...
