Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cashmere processing, and specifically relates to a multiple-screening fiber impurity removal device. Background Art
[0002] Cashmere is a thin layer of fine wool that grows on the outer skin of goats and hides at the roots of their coarse hair. The processed cashmere is a high-quality material for clothing coats. When processing the cashmere raw materials, there will inevitably be dirt and impurities (dead skin, grass seeds, dust, etc.) on its surface. Therefore, it is necessary to loosen and remove impurities before combing. Only after the impurities are fully removed can further processing be carried out.
[0003] The wool collected and purchased is often in the form of clumps, and contains many impurities. Therefore, the wool needs to be broken up before processing to make it fluffy before screening and removing impurities. At present, there is a lack of special equipment for screening and removing impurities. Most of them use manual shaking and simple screen filtering, so the impurity removal effect is not ideal, which directly affects the processing quality of subsequent combing. Utility Model Content

[0014] Figure 1 The utility model is a structural schematic diagram of a double-screen fiber impurity removal device. DETAILED DESCRIPTION
[0015] The structure and working principle of the novel multi-screen fiber impurity removal device provided by the utility model are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] In the description of the present invention, unless otherwise specified, the orientation or positional relationship indicated in the terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0017] It should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "setting" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0018] like Figure 1 As shown, the structure of the novel multiple-screen fiber impurity removal device includes a frame 1, an inner drum 31 and an outer drum 32 which are arranged in the frame 1 and are fitted together through a bearing ring 2, screens are arranged on the bodies of the two drums and the mesh diameter of the inner drum 31 is larger than the mesh diameter of the outer drum 32, a feed port 41 is arranged at one end of the inner drum 31, a discharge port 42 is arranged at the other end thereof, a discharge port 43 is arranged at the end of the annular area between the inner drum 31 and the outer drum 32, the inner drum 31 and the outer drum 32 are connected to the first motor 51 and the second motor 52 respectively through a first transmission mechanism and a second transmission mechanism, and each realizes rotation and screening of materials.
[0019] Its working principle is as follows: the inner drum 31 and the outer drum 32 in the frame 1 of the device are integrated into one body through the bearing ring 2, and screens are provided on the drum bodies. The cashmere raw material is fed from the feed port 41 of the inner drum 31 and then rotated for screening. The cashmere-containing dirt and impurities are filtered through the screen into the outer drum 32 for rotation screening, and the dirt and impurities are gradually separated from the original cashmere. Pure dirt and impurities are discharged from the screen of the outer drum 32, and the original cashmere can be recovered from the discharge port 43 or continue to be fed into the inner drum 31 for secondary screening.
[0020] It should be noted that the inner drum 31 and the outer drum 32 each have an independent transmission system and power mechanism, and move relative to each other without interfering with each other. Of course, the split-phase transmission structure in the prior art can also be used to achieve one power to drive the two drums to work separately.
[0021] In the structure constituting the above-mentioned novel multi-screen fiber impurity removal device,
[0022] In one embodiment, the first transmission mechanism includes a rotating shaft 61, which is disposed at the axis of the inner drum 31 and connected to the inner wall of the inner drum 31 through a plurality of supporting rods 62. The end of the rotating shaft 61 is connected to the first motor 51 through a coupling 60, that is, the first motor 51 drives the rotating shaft 61 to rotate, thereby driving the inner drum 31 to rotate. As an equivalent alternative, the end of the rotating shaft 61 can be connected to the output shaft of the first motor 51 through a transmission belt to achieve power transmission.
[0023] - Preferably, a plurality of stirring blades or stirring rods 63 are provided on the rotating shaft 61. When rotating and screening the cashmere raw materials, the stirring blades or stirring rods 63 can break up the wool aggregates and speed up the screening and impurity removal efficiency;
[0024] ——Furthermore, support seats 71 are respectively provided at both ends of the outer drum 32, and a plurality of rollers 72 are contained in the support seats 71. The body of the outer drum 32 can rotate on the rollers 72 arranged side by side. The second transmission mechanism includes a gear ring 81 mounted on the body of the outer drum 32 and a gear 82 meshing with the gear ring 81. The gear 82 is mounted on the output shaft of the second motor 52, that is, the second motor 52 drives the gear 82 to rotate, thereby driving the gear ring 81 and the outer drum 32 to rotate synchronously;
[0025] As a preferred embodiment, the cross-sections of the inner drum 31 and the outer drum 32 are isosceles trapezoids, that is, the shapes of the inner drum 31 and the outer drum 32 are both trumpet-shaped. When the structure rotates, the centrifugal force gradually increases, which has a dispersion effect and is more conducive to the screening of dirt and impurities. In addition, one end of the inner drum 31 with the discharge port 42 extends out of the outer drum 32, which is convenient for timely discharge of the cashmere after impurities removal;
[0026] ——Preferably, the inner drum 31 and the outer drum 32 rotate in opposite directions. For example, after counterclockwise rotation screening is performed in the inner drum 31, the cashmere-containing dirt and impurities enter the outer drum 32 for clockwise rotation screening. Such multi-directional reciprocating screening can completely separate the dirt and impurities from the cashmere, thereby improving the screening quality and efficiency. Furthermore, the rotation speed ratio of the inner drum 31 to the outer drum 32 is in the range of (2-5):1. In actual work, the reciprocating screening effect is better.
[0027] The above-described implementation modes are only used to illustrate the technical solution of the utility model, and are not limiting conditions for the implementation of the utility model. Therefore, any other modifications or equivalent replacements of configuration dimensions and internal structures made to the technical solution of the utility model, as long as they do not depart from the spirit and scope of the technical solution of the utility model, should be included in the scope of the claims of the utility model.
