[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments: Refer to Figure 1-Figure 8 , an embodiment of a one-step spinning machine for forward cohesion and twisting of the present invention, including a frame, an opening roller 2, an opening roller cover, a fiber feeding mechanism 1, a forward cohesion and twisting mechanism, and a yarn winding mechanism 6 and a suction device, an opening roller 2 and an opening roller cover are arranged on the frame, a fiber feeding mechanism 1 is arranged on one side of the opening roller 2, and a fiber feeding mechanism 1 connected to the opening roller cover is arranged under the other side of the opening roller 2 Shaped tube 3. The fiber feeding mechanism 1 is a cotton feeding roller and a cotton feeding plate or a pair of hair feeding rollers. The special-shaped tube 3 is formed by butting a conical tube 3-1 and a trapezoidal tube 3-2. The large-diameter end of the conical The inlet end of the trapezoidal tube 3-2 is communicated, and the other end of the trapezoidal tube 3-2 is the outlet end. The trapezoidal pipe 3-2 is composed of a pair of trapezoidal flat plates forming two sides of the pipe wall and a pair of trapezoidal mesh plates forming the upper and lower sides of the pipe wall. The section from the inlet to the outlet end of the trapezoidal tube 3-2 gradually changes from a square to a flat rectangle. The width of the trapezoidal flat plate at the outlet end is the largest, while the width of the trapezoidal mesh plate is the smallest. A semi-circular arc mesh plate is arranged on the outlet end of the trapezoidal pipe 3-2, and the axis of the semi-circular arc mesh plate is parallel to the outlet end face of the trapezoidal pipe 3-2. The suction device is arranged outside the semi-circular arc-shaped mesh plate, and a U-shaped condensation area 4 with negative pressure is formed in the semi-circular arc-shaped mesh plate. The forward twisting mechanism is a swirl twisting tube 5 that is connected to one end of the semi-circular arc mesh plate in the forward direction. The inner diameter of the tube 5 is completely consistent with the arc shape of the U-shaped condensation zone 4, forming a straight and smooth yarn path.

[0033] Image 6 , Figure 7 As shown, three air inlet holes 5-1 evenly distributed on the side wall of the swirl twisting tube 5 are inclined and distributed evenly along the circumference of the side wall of the swirl twisting tube 5. The included angle of the inner diameter axis of the twisting tube 5 is 40°-50°, and is tangent to the circumferential surface of the inner cavity 5-2 of the swirl twisting tube. An air compressor is connected to the air inlet 5-1 through a pipeline, and the compressed air enters along the air inlet hole 5-1 to form a forward swirl to complete the twisting of the whiskers and push the yarn forward.

[0034] Figure 2-Figure 4As shown, a pair of trapezoidal mesh plates and semi-circular arc mesh plates of the above-mentioned trapezoidal tube 3-2 are made of stainless steel, the mesh density is 2800-3200 mesh, and a pair of trapezoidal flat plates of the trapezoidal tube 3-2 are stainless steel plates. The trapezoidal tube 3-2 is connected to the conical tube 3-1 through, the inlet end of the trapezoidal tube 3-2 is a square section, the side length is 12-24mm, such as cotton type is about 14mm, wool type is about 20mm; 3-2 The outlet end is a rectangular section, the side length is (50-100mm)×(3-9mm), the cotton type is about 55mm×3mm, the wool type is about 90mm×5mm, and the length of the trapezoidal tube 3-2 is 80-120 mm mm. The inner diameter of the tapered tube 3-1 is tapered conical, and the inner diameter of the outlet of the tapered tube 3-1 is smaller than the inner diameter of the inlet. The inner diameter outlet of the tapered tube 3-1 is a circle with a diameter of 8-20mm, such as cotton fiber: the inner diameter outlet diameter of the tapered tube 3-1 is about 10mm, and the hair type fiber: the inner diameter outlet diameter of the tapered tube 3-1 is 15mm about. The wall thickness of the tapered tube 3-1 gradually becomes thicker from the inlet to the outlet, the shape and size of the inlet of the tapered tube 3-1 are consistent with the opening roller cover, the outer diameter of the outlet end of the tapered tube 3-1 is square, and the cone The outer diameter of the square outlet end of the shaped pipe 3-1 is consistent with the size of the square inlet end of the trapezoidal pipe 3-2, and the special-shaped pipe 3 is formed by butt joint. In the special-shaped tube 3, fiber transportation and cohesion (fiber straightening, paralleling, turning, coagulation and merging) are completed in one step.

[0035] The above-mentioned suction device includes a suction fan and a suction pipe 7 thereof, and the suction pipe 7 is arranged at a position close to the outlet end of the trapezoidal pipe 3-2. The material of the suction pipe 7 adopts alloy or hard plastic, and the suction pipe 7 The mouth shape is trapezoid.

[0036] like Figure 5 As shown, the U-shaped agglomeration zone 4 at the end of the special-shaped tube 3 adopts an arc-shaped mesh plate, and the radius of the U-shaped agglomeration zone 4 is 3-9mm, which can be changed according to the weight of the feeding whiskers. In the U-shaped agglomeration zone 4, the external suction fan generates negative pressure through the suction pipe 7 to generate negative pressure, so that the fibers can be smoothly coagulated in the U-shaped agglomeration zone 4, and maintain a certain tension when the fibers are drawn out to keep the fibers straight.

[0037] An embodiment of the one-step spinning method using the above-mentioned forward poly-twist one-step spinning machine of the present invention includes the following process steps:

[0038] The raw sliver is fed into the opening roller cover by the fiber feeding mechanism. The opening roller 2 further separates the fibers, and the air flow in the special-shaped tube 3 makes the fibers fully straighten and turn, and the end of the special-shaped tube 3 achieves completely parallel condensation. In the U-shaped condensing zone 4 with negative pressure at the end, the fibers are condensed in the heterosexual tube. The compressed air formed by the air compressor enters the swirl twisting tube 5 along the air inlet 5-1, and the finally condensed fibers are compressed by the compressed air. A forward swirl is formed to complete the twisting of the whiskers and push the yarn forward, and lead out in parallel with the U-shaped condensation zone 4, so as to realize the smooth twisting of the whiskers in the forward direction, and obtain the true twist. The winding mechanism 6 is wound to form the yarn.

[0039] In the above method: the bottom of the U-shaped agglomeration zone 4 is a semi-circular arc mesh plate, and the outside of the semi-circular arc mesh plate has a suction pipe 7 connected by a suction fan to suck air, keep the negative pressure of the U-shaped agglomeration zone 4, and make the fibers condense smoothly. In the U-shaped cohesion zone 4, and maintain a certain tension when the fibers are drawn out, so that the fibers remain in a straight state; the swirl twisting tube 5 generates a forward swirling flow, and the whiskers in the U-shaped cohesion zone 4 are drawn out and added. True twist to get a smooth and straight yarn.

[0040] The specific yarn forming principle is as follows:

[0041] 1. Fiber coagulation method. The fiber conveying mechanism is perfectly combined with the coagulation zone, so that the fibers are fully straightened and turned, and smoothly coagulated in the U-shaped cohesion zone 4. The conveying and coagulation process is direct and smooth, and the fibers are straightened and must be in a limited space. Strip even target.

[0042] 2. The method of twisting the whiskers in the forward direction. After the fibers are combined and agglomerated in the agglomeration zone, the specially installed swirl twisting tube 5 is perfectly connected to the U-shaped agglomeration zone 4, and the fibers are drawn out in the forward direction, and the true twist is applied under the action of the swirling flow of the swirl twisting tube 5.

[0043] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples. Those of ordinary skill in the art, within the essential scope of the present invention, make changes, modifications, additions or substitutions. It belongs to the protection scope of the present invention.
