Description

Technical Field

[0001] The present application relates to the technical field of fiber raw material mixing, and in particular to a spinning fiber raw material mixing device and a mixing method. Background Art

[0002] In the field of mixing spinning fiber raw materials, static electricity has always been an important factor affecting the mixing effect and product quality. In the traditional spinning fiber raw material mixing process, static electricity is often generated due to friction, contact separation and other effects between the fiber raw materials. These static electricity will cause the fiber raw materials to adsorb or agglomerate with each other, making the mixing uneven, which in turn affects the quality and performance of the spinning. For example, fiber raw materials in the form of fiber raw materials are easily entangled together under the action of static electricity, resulting in local fiber raw material accumulation and fiber raw materials missing in other areas. Summary of the invention

[0003] The purpose of the present application is to provide a spinning fiber raw material mixing device and a mixing method in order to solve the problem of static electricity in the fiber raw materials during the mixing process.

[0005] By adopting the above technical solution, the power mechanism drives the cylindrical barrel to rotate in a circular motion, so that the fiber raw materials can be continuously tumbled and mixed in the barrel. During the stirring process, the spiral plate is continuously lifted. On the one hand, the fibers at the bottom are moved upward to increase the uniformity of the mixing. On the other hand, the spiral plate lifts the fibers to the top of the polarization zone. When the fibers fall, the first electrode plate and the second electrode plate polarize the fibers so that the fibers carry the same charge. In this way, the fibers are repelled by the same charges during the mixing process, making the mixing more uniform.

By adopting the above technical solution, the motor drives the rotating frame to rotate through the connecting shaft, so that the cylindrical barrel body rotates circumferentially around the center. While the cylindrical barrel body rotates circumferentially, due to the meshing of the planetary gear and the annular rack, the planetary gear will rotate on its own, so that the spiral plate can rotate, thereby achieving the lifting of the fiber raw material during the stirring process, so that the fiber raw material at the bottom can be flipped up, and secondly, preparation is made for multiple polarizations.

[0007] Optionally, the inner wall of the bottom of the mixing box is an inclined surface, and an inclined column is provided in the mixing box. The inclined column and the inclined surface of the inner wall of the bottom of the mixing box form an inclined annular groove, and the cylindrical barrel rotates circumferentially in the inclined annular groove.

[0008] By adopting the above technical scheme, when the fiber raw materials at a high place of transportation fall, due to the existence of the inclined slide groove, the fallen fiber raw materials will fall into the inclined ring groove, which is convenient for the cylindrical barrel to stir the fiber raw materials. While pushing the fiber raw materials to both sides, the fiber raw materials will fall back into the inclined ring groove, so that the mixing effect is good.

[0009] Optionally, a rotating plate group is rotatably connected to the inner side of the inner shell, the cylindrical barrel penetrates the rotating plate group, a polarization box is provided on the rotating plate group, the polarization box is connected to the mixing box, a third electrode plate and a fourth electrode plate are respectively provided on both sides of the polarization box, the polarization box is provided with a dust cleaning box, and the dust cleaning box is provided with a feeding pipe.

[0010] By adopting the above technical solution, the added fiber raw material is firstly cleaned of dust at the feed point of the device to reduce impurities in the fiber raw material, and then the fiber raw material is polarized for the first time by the third electrode plate and the fourth electrode plate, so that the fiber raw materials have the same charge before stirring and mixing.

[0011] Optionally, the concave annular groove is arranged between the mixing box and the inner shell body, the concave annular groove can rotate between the mixing box and the inner shell body, the concave annular groove is provided with an annular groove with an opening facing the polarization zone, the annular groove is connected to the cylindrical barrel body, an annular plate is slidably connected in the annular groove, a through hole is provided on the annular plate, an annular corrugated groove is provided on the inner wall of the mixing box body, a sliding block is provided in the annular corrugated groove, and the sliding block is fixedly connected to the annular plate.

[0012] By adopting the above technical solution, the annular plate continuously vibrates up and down under the action of the annular corrugated groove and the sliding block during the stirring process, and the fiber raw material transported to the annular groove can be scattered into the polarization zone under the action of the vibration. In this way, the scattered fiber raw material is polarized again by the first electrode plate and the second electrode plate during the spreading process. Since the fiber raw material is relatively dispersed during the spreading process, the polarization effect is strong.

[0013] A method for mixing raw materials for spinning fibers, characterized in that it comprises the following steps: S1, putting the fiber raw material a into the dust cleaning box through the feeding channel; S2, using a dust cleaning box to remove dust contained in the fiber raw material a; S3, the fiber raw material a after dust removal passes between the third electrode plate and the fourth electrode plate, and undergoes polarization treatment, so that the fiber raw material a presents positive / negative charge; S4, adding different types of fiber raw materials, repeating the above steps S2 to S3 until all fiber raw materials have been added; S5, the cylindrical barrel starts stirring.

After the stirring is completed, the uniformly mixed fiber raw material is transported to the next process.

[0014] By adopting the above technical solution, the fiber raw materials are made to carry the same charge before stirring and mixing, so that the occurrence of agglomeration of the fiber raw materials is reduced under the effect of charge repulsion, and the fiber raw materials are mixed more evenly. Therefore, the fiber raw materials are first polarized by the third electrode plate and the fourth electrode plate. In order to avoid charge dissipation during the stirring process, the fiber raw materials are continuously lifted and sprinkled, and polarized again during the sprinkling process.

[0015] In summary, the present application includes at least one of the following beneficial technical effects: 1. Before mixing, the fiber raw materials are subjected to polarization treatment to make them have the same electrical properties, so as to avoid static electricity generated by friction, which causes the fiber raw materials to attract each other and form clumps. At the same time, the repulsive effect of charges helps to evenly distribute the fiber raw materials; 2. During the stirring process, the lifting of the spiral plate and the uniform spreading of the concave ring groove enhance the longitudinal mixing effect, allowing different fiber raw materials to be mixed more fully and evenly. In the stirring and mixing process, part of the fiber raw materials are repolarized to avoid charge dissipation affecting electrostatic repulsion and mixing effect. BRIEF DESCRIPTION OF THE DRAWINGS

This force is like a strong hand, trying to change the motion state of the electrons. If the direction of the electric field is from the fiber outward, it will produce an outward pulling force on the electrons on the fiber surface, causing the fiber surface to lose electrons and thus carry a positive charge. On the contrary, if the direction of the electric field is pointing to the inside of the fiber, it will produce an inward thrust on the external electrons, and it is possible to "inject" the external electrons into the fiber surface. In this way, the fiber surface gains extra electrons and thus carries a negative charge; similarly, when different fibers a2, a3,...an are added, the fibers will be given the same charge; the added fibers will gather in the inclined ring groove 11, and the cylindrical barrel 4 rotates around the center of the inclined ring groove 11 driven by the motor 3, and the cylindrical barrel 4 stirs the fibers in a circular motion. During the stirring process, the spiral plate 42 transports the fibers at the bottom to the concave ring groove 7, and the concave ring groove 7 evenly distributes the fibers to the polarization zone 6, and the fibers are polarized multiple times by the first electrode plate 61 and the second electrode plate 62, thereby realizing the function of polarization while stirring during the stirring process, thereby avoiding the influence of charge dissipation on electrostatic repulsion and mixing effects.
