Description

Technical Field

[0001] This utility model relates to the field of textile fiber mixing technology, and in particular to a device for efficient mixing and uniform dispersion of textile fibers. Background Technology

[0002] In the textile processing industry, the efficient mixing and uniform dispersion of fiber raw materials are key factors determining the quality of subsequent spinning, weaving, and other processes. Traditional textile fiber mixing equipment often employs a simple double-roller method. For example, existing technology (authorization announcement number CN218561715U) discloses a cotton blending machine that uses two rotating blending rollers to tear the cotton material, thereby thoroughly mixing it, improving the quality of the cotton material in later processing, and collecting it into a fixed collection box. Inside the fixed collection box, there is a collection frame that collects the mixed cotton material, and a weighing meter inside the collection frame measures the cotton material, making it more accurate and achieving the effect of automatic metering.

[0003] Based on existing technology, fiber raw materials (such as cotton, polyester staple fiber, etc.) are often loose in their initial form and have a high impurity content, which makes them prone to agglomeration or accumulation when entering the mixing area. This results in incomplete opening and large cotton clumps remaining on the inner wall of the equipment (such as side baffles and roller gaps), affecting the uniformity of mixing. Therefore, this utility model proposes a high-efficiency mixing and uniform dispersion device for textile fibers to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a highly efficient mixing and uniform dispersion device for textile fibers. This device has the advantage of improving the mixing effect of textile fibers and can solve the problems in the prior art.

[0005] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a textile fiber high-efficiency mixing and uniform dispersion device, including a mixer shell, a discharge port installed at the lower end of the mixer shell, a feed port opened at the upper end of the mixer shell, arc-shaped elastic baffles installed on both sides inside the mixer shell, a timed striking component installed on both sides of the mixer shell, and the position of the timed striking component corresponds to the arc-shaped elastic baffle, a loosening roller is provided between the arc-shaped elastic baffles on both sides, and there are several sets of loosening rollers, the upper ends of the several sets of loosening rollers are connected to the mixer shell through bearings and driven by a first motor, two sets of symmetrically arranged mixing rotating rollers are installed on the inner side of the mixer shell, a dispersing roller is provided below the two sets of mixing rotating rollers, both ends of the dispersing roller are connected to the mixer shell through bearings and driven by a second motor, and disturbance components are installed on both sides inside the mixer shell.

[0006] A further improvement is that both ends of the two sets of mixing rotating rollers are connected to the mixer housing via bearings and driven by a third motor. One set of mixing rotating rollers passes through the mixer housing and is equipped with a drive gear, while the other set of mixing rotating rollers passes through the mixer housing and is equipped with a driven gear. The diameter of the drive gear is larger than that of the driven gear, and the drive gear and the driven gear are meshed and connected by a transmission gear. There are two sets of transmission gears.

[0007] A further improvement is that the timing striking component includes a reciprocating cylinder, which is provided in several groups, and the reciprocating cylinder is fixedly connected to the mixer housing through a bracket. The telescopic end of the reciprocating cylinder passes through the mixer housing and is equipped with a rubber striking head. The control end of the reciprocating cylinder integrates a timer.

[0008] A further improvement is made in that: the disturbance component includes two sets of symmetrically arranged fixed seats, the inner side of the fixed seats is provided with a cavity, and the end of the fixed seat facing the dispersing roller is provided with an arc-shaped structure. The fixed seats are provided with air vents, and several sets of air vents are evenly arranged. Air inlet pipe connectors are installed on both sides of the mixer shell. The air inlet pipe connectors are connected to the cavity, and the air inlet pipe connectors are connected to the output end of the external fan through pipes.

[0009] A further improvement is that the feed inlet is symmetrically provided in two sets, and the two sets of feed inlets are located on the left and right sides above the opening roller, respectively.

[0010] A further improvement is that the surfaces of both the opening roller and the mixing roller are covered with first steel needles, and the first steel needles are evenly arranged in several groups.

[0011] A further improvement is that: the surface of the dispersing roller is distributed with second steel needles, the length of the second steel needles is greater than that of the first steel needles, and the second steel needles are evenly arranged in several groups.

[0012] The beneficial effects of this utility model are as follows: This utility model can loosen the textile fibers before mixing by setting the opening roller, and then mix them. After that, the dispersion roller and the disturbance component work together to further promote the dispersion and uniformity of the materials. Compared with the double roller mixing method, the mixing and dispersion effect of this utility model is higher, and the mixing efficiency is further enhanced. Attached Figure Description

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figures 1-4 As shown in the figure, this embodiment proposes a device for efficient mixing and uniform dispersion of textile fibers, including a mixer shell 1, a support column installed at the lower end of the mixer shell 1, and four sets of support columns are evenly arranged. A discharge port 2 is installed at the lower end of the mixer shell 1, and an openable discharge cover is installed at the lower end of the discharge port 2. When discharge is required, the discharge cover is opened to discharge the material.

[0021] The upper end of the mixer shell 1 is provided with a feed inlet 3. Two sets of feed inlets 3 are symmetrically arranged, and the two sets of feed inlets 3 are located on the left and right sides above the opening roller 5, respectively, which serve as a feeding function.

[0022] Arc-shaped elastic baffles 4 are installed on both sides inside the mixer housing 1. The front and rear ends of the arc-shaped elastic baffles 4 are fixedly connected to the inner wall of the mixer housing 1, covering the area where textile fiber raw materials fall inside the mixer housing 1. Timed striking components are installed on both sides of the mixer housing 1, and the positions of the timed striking components correspond to the arc-shaped elastic baffles 4. The timed striking components include reciprocating cylinders 11, with several sets of reciprocating cylinders 11. The reciprocating cylinders 11 are fixedly connected to the mixer housing 1 via brackets. In this embodiment, three sets of reciprocating cylinders 11 are installed on each of the left and right sides of the mixer housing 1, for a total of six sets. The telescopic end of the reciprocating cylinder 11 passes through the mixer housing 1 and is equipped with a rubber striking head 12. The control end of the reciprocating cylinder 11 integrates a timer. The drive of each reciprocating cylinder 11 is controlled by an independent timer. During operation, when the textile fiber raw material is initially opened by the opening roller 5, it collides with the arc-shaped elastic baffle 4 due to the inertia of falling. Some fibers will adhere to the surface of the arc-shaped elastic baffle. At this time, the timer triggers the action of the reciprocating cylinder 11 according to the preset program (such as striking once every 30 seconds). The telescopic end of the reciprocating cylinder 11 pushes the striking head 12 to quickly strike the arc-shaped elastic baffle 4. The arc-shaped elastic baffle 4 is impacted and generates high-frequency micro-amplitude vibration. The fibers attached to its surface are detached from the arc-shaped elastic baffle 4 due to vibration and slide down along the arc of the baffle to the working area of ​​the mixing rotating roller 7 below, thereby avoiding fiber accumulation and ensuring the continuity and uniformity of subsequent mixing processes.

[0023] A loosening roller 5 is provided between the corresponding two arc-shaped elastic baffles 4, and several sets of loosening rollers 5 are provided. In this embodiment, three sets of loosening rollers 5 are evenly provided, and the three sets of loosening rollers 5 are arranged along the length direction of the arc-shaped elastic baffles 4. The upper ends of the several sets of loosening rollers 5 are connected to the mixer housing 1 through bearings and driven by a first motor 6 (the first motor 6 is located above the mixer housing 1 and is fixedly connected to the mixer housing 1 through a bracket). The surface of the loosening roller 5 is distributed with first steel needles 17, and several sets of first steel needles 17 are evenly provided (arranged in a spiral shape along the axial direction of the loosening roller 5, with a pitch of 15 mm and a density of 8 needles / cm). 2During operation, textile fiber raw materials enter and first come into contact with the first steel needle 17 on the opening roller 5. The first steel needle 17, with its sharp tip, hooks the edge of the fiber clump, and uses the shearing force generated by the circumferential motion of the roller to tear the large fiber clump into smaller fiber bundles. During this process, some fibers (referring to textile fiber raw materials) are fixed to the surface of the roller due to the hooking action of the steel needle and stay there briefly. They then rotate with the roller to the bottom of the roller (i.e., the side away from the feed inlet), while the textile fiber raw materials that are not completely fixed continue to move downward due to inertia. Subsequently, the torn fiber bundles (or the textile fiber raw materials that are not completely fixed) detach from the surface of the opening roller 5 under the action of gravity and inertia and move downward. At this time, the arc-shaped elastic baffle 4 is located on both outer sides below the opening roller 5 (the arc matches the falling trajectory of the textile fiber raw materials, and the opening faces the direction of the mixing rotating roller 7). The textile fiber raw materials splash or fall freely due to inertia and collide with the arc-shaped surface of the arc-shaped elastic baffle 4. The elastic material of the arc-shaped elastic baffle 4 can buffer the impact of fiber collision and prevent the fiber from breaking due to violent impact. At the same time, the arc of the arc-shaped elastic baffle 4 guides the textile fiber raw material to gather in the middle and lower part of the arc-shaped elastic baffle 4, preventing the textile fiber raw material from flying to both sides.

[0024] The initial loosening process lays the foundation for subsequent uniform mixing in the mixing roller 7.

[0025] Two sets of symmetrically arranged mixing rollers 7 are installed on the inner side of the mixer housing 1. Both ends of the shafts of the two sets of mixing rollers 7 are connected to the mixer housing 1 through bearings and driven by a third motor (the third motor is not shown in the figure, but it is located on the outer side of the mixer housing 1 and is fixedly connected to the mixer housing 1 through a bracket). The shaft of one set of mixing rollers 7 passes through the mixer housing 1 and is equipped with a drive gear 9. The shaft of the other set of mixing rollers 7 passes through the mixer housing 1 and is equipped with a driven gear 10. The diameter of the drive gear 9 is larger than that of the driven gear 10, and the drive gear 9 and the driven gear 10 are connected by a transmission gear meshing. There are two sets of transmission gears (therefore, one set of mixing rollers 7 rotates clockwise and the other set of mixing rollers 7 rotates counterclockwise).

[0026] Furthermore, because the diameter of the driving gear 9 is larger than that of the driven gear 10, the rotational speeds of the two sets of mixing rollers 7 are inconsistent. This speed difference generates additional tensile and shear forces, forcing the fibers to repeatedly "pull and separate" between the two rollers, breaking up local agglomerations. At the same time, the surface of the mixing rollers 7 is also covered with first steel needles 17. Several sets of first steel needles 17 are evenly distributed, which can physically grasp and stir the textile fibers during the mixing process, ensuring close contact and thorough stirring between the fibers and preventing fiber agglomeration.

[0027] Below the two sets of mixing rollers 7, there is a dispersing roller 8. Both ends of the dispersing roller 8 are connected to the mixer housing 1 through bearings and are driven by a second motor. The surface of the dispersing roller 8 is distributed with second steel needles 18, the length of which is greater than that of the first steel needles 17. The function of the dispersing roller 8 is to further disperse the mixed material. The second steel needles 18 are longer, so they can generate greater physical interference and gripping force on the fibers or particles during the roller rotation, effectively promoting the dispersion of the material and avoiding uneven mixing or agglomeration.

[0028] Both sides of the mixer housing 1 are equipped with disturbance components, which include two sets of symmetrically arranged fixed seats 13. The inner side of the fixed seat 13 is provided with a cavity, and the end of the fixed seat 13 facing the dispersing roller 8 is provided with an arc-shaped structure 14. The fixed seat 13 is provided with air vents 15, and several sets of air vents 15 are evenly arranged. Both sides of the mixer housing 1 are equipped with air inlet pipe connectors 16. The air inlet pipe connectors 16 are connected to the cavity, and the air inlet pipe connectors 16 are connected to the output end of the external fan through the pipe. When working, the external fan is started, and the airflow is sprayed out through the air vents 15, which can blow the mixed fibers to the working range of the dispersing roller 8 for further dispersion, thereby further promoting the dispersion and uniformity of the material.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
