Description

Technical Field

[0001] The utility model relates to the field of absorbent cotton production, in particular to a device for forming cotton fibers. Background Art

[0002] During the production of absorbent cotton, the cotton fibers need to be degreased. In the prior art, the degreasing process is generally performed by wetting the cotton fibers and then squeezing them into round cakes in a molding device. The formed cotton cakes are then sent to a degreasing kettle for degreasing, and then the degreased cotton fibers are dehydrated. The molding device currently used is to send the cotton fibers into a molding barrel that rotates around its central axis through a feed pipe. After piling up to a corresponding height, the fibers are squeezed and shrunk by an extrusion device. Although this operation method can produce corresponding cotton cakes, it has the following defects: during the feeding process, manual assistance is required to evenly spread the fallen fabrics. In addition, after the cotton fibers are piled up to a certain height, an extrusion device is used for extrusion. The extruded cotton fiber cakes are relatively loose and easy to rebound. At the same time, the feed pipe and the extrusion mechanism need to be installed movably to avoid mutual interference. Summary of the Invention

DETAILED DESCRIPTION

[0026] To make the objectives and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following description is merely intended to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection claimed herein. As used herein, the terms "parallel," "perpendicular," and the like are not limited to their strict mathematical definitions but include tolerances for machining errors and other reasonable variations.

[0027] like Figures 1 to 8 As shown, a device for forming cotton fibers includes a receiving barrel 30 for receiving wet cotton material. The upper portion of the receiving barrel 30 has a barrel opening. The receiving barrel 30 is rotatably mounted on a forming machine frame and connected to a rotation adjustment mechanism. The rotation adjustment mechanism is used to adjust the rotation of the receiving barrel 30 along its vertical centerline. The upper side of the receiving barrel 30 is provided with a distributing mechanism for distributing wet cotton material into the receiving barrel 30, and a tamping mechanism 20 for tamping the wet cotton material in the receiving barrel 30 layer by layer. The tamping mechanism 20 and the distributing mechanism are sequentially arranged along the rotation direction of the receiving barrel 30. The tamping mechanism 20 tamps the wet cotton material entering the barrel layer by layer, so that the cotton cake formed is more solid and uniform, which facilitates the uniformity and production efficiency of the subsequent degreasing process.

[0028] A further solution is, Figure 1 、 3As shown: the receiving barrel 30 has an annular material distribution area, and the tamping mechanism 20 includes a tamping block 25 and a vertical adjustment component radially arranged in the material distribution area along the receiving barrel 30. The tamping block 25 is movably installed in the vertical direction, and the vertical adjustment component is used to adjust the movement of the tamping block 25 in the vertical direction. By adjusting the vertical movement of the tamping block 25, the material on the lower side is compacted layer by layer, thereby ensuring the reliability of the tamping material. A plurality of tamping blocks 25 are arranged at circumferential intervals along the receiving barrel 30. Preferably, two tamping blocks 25 are arranged at circumferential intervals along the receiving barrel 30, and the vertical adjustment component adjusts the two tamping blocks 25 to be staggered and lifted. By setting two tamping blocks 25, when one tamping block 25 is lowered to tamping material, the other tamping block 25 is adjusted to lift, thereby increasing the tamping rate and shortening the time for cotton fiber molding.

[0029] In detail: The tamping mechanism 20 is mounted on a tamping mounting seat 22, which is vertically mounted on a tamping frame. The tamping frame is provided with a tamping adjustment mechanism 29 for adjusting the tamping mounting seat 22 for elevation. The tamping adjustment mechanism 29 adjusts the mounting seat for elevation. As the height of the cotton fibers within the receiving barrel 30 increases, the position of the tamping mechanism 20 is adjusted accordingly, thereby increasing the single-time processing capacity of the receiving barrel 30. The lower surface of the tamping block 25 is provided with tamping bumps 26 arranged in a raised manner. Because the surface of the fiber cotton after being laid is not smooth and uniform, the raised portions can further adjust this unevenness and uniformity, improving the uniformity of the formed cotton cake and facilitating subsequent processing. Preferably, two rows of tamping bumps 26 are provided on the lower surface of the tamping block 25, with the tamping bumps 26 in the two rows arranged in an alternating pattern. This arrangement optimizes the uniformity of the cotton fibers and ensures uniformity along the circumferential direction. The two tamping blocks 25 are respectively mounted on the lower ends of the two tamping rods 27. The two tamping rods 27 are arranged vertically and slidably mounted on the tamping mounting seat 22 in the vertical direction. The vertical adjustment assembly includes a dual-output reducer 24 mounted on the tamping mounting seat 22. The input end of the dual-output reducer 24 is transmission-connected to the tamping motor. The two output ends of the dual-output reducer 24 are concentrically arranged and provided with transmission cranks respectively. The transmission cranks are transmission-connected to the upper ends of the tamping rods 27 through transmission connecting rods. The two sets of crank-connecting rod mechanisms are driven by the tamping motor to adjust the two tamping blocks 25 to perform the tamping operation alternately, thereby ensuring the reliability and efficiency of the tamping. The ramming frame includes a forming tray 11 for supporting a receiving barrel 30 and a ramming column 21 located beside the forming tray 11. The forming tray 11 is rotatably mounted and connected to a forming drive motor that adjusts its rotation. A ramming mounting seat 22 is slidably mounted on the ramming column 21. A ramming adjustment mechanism 29 includes a ramming cylinder or a ramming liquid cylinder connected to the ramming mounting seat 22. The receiving barrel 30 clamped on the forming tray 11 is adjusted to rotate by the forming drive motor, thereby achieving reliable distribution and ramming of the material at all circumferential locations of the receiving barrel 30. One end of the ramming cylinder or the ramming liquid cylinder is connected to the ramming mounting seat 22, and the other end is assembled and connected to the ramming column 21. The height of the ramming mechanism 20 is adjusted by the ramming cylinder or the ramming liquid cylinder to match the height of the material in the receiving barrel 30, ensuring the consistency of the strength of the interlayer ramming.

[0030] A further solution is to provide a first positioning unit and a second positioning unit on the upper surface of the build tray 11 for mounting the receiving bucket 30. The first positioning unit comprises a first boss 12 located in the middle of the upper surface of the build tray 11, with first positioning plates 18 radially arranged around the first boss 12. The second positioning unit comprises second bosses located outside the first positioning plates 18, and the second bosses are spaced apart along the circumference of the build tray 11. The first and second positioning units ensure that the receiving bucket 30 is securely clamped to the build tray.

[0031] A more preferred embodiment is as follows Figure 6 、 7 8: The feeding mechanism includes a first feeding unit 1a and a second feeding unit 1b which are spaced apart circumferentially along the receiving barrel 30. The first feeding unit 1a includes a first feeding pipe 13. The discharge end of the first feeding pipe 13 is vertically downward and arranged corresponding to the feeding area. The feed end of the first feeding pipe 13 is connected to the cotton fiber air conveying equipment. The cotton fiber air conveying equipment transports cotton fibers by air conveying. A first water spraying mechanism 14 for spraying water to the cotton fibers is provided on the wall of the discharge end of the first feeding pipe 13. The first water spraying mechanism 14 includes a first annular water spraying pipe. First nozzles are spaced apart on the first water spraying pipe. The water spraying direction of the first nozzle is obliquely downward pointing to the middle of the discharge end of the first feeding pipe 13. The feeding mechanism includes a first feeding unit 1a and a second feeding unit 1b spaced apart along the circumference of the receiving barrel 30. The second feeding unit 1b includes a second feeding pipe 15, the discharge end of which faces vertically downward and is arranged corresponding to the feeding area. The feed end of the second feeding pipe 15 is connected to the cotton fiber air conveying device. A conical material stopper 17 is provided inside the discharge end of the second feeding pipe 15. The stopper 17 is fixedly mounted on the second feeding pipe 15, forming a channel for the cotton fiber to pass through. The stopper 17 is provided with a first water spraying mechanism 14 for spraying water on the cotton fiber. The first water spraying mechanism 14 includes an annular second water spraying pipe with second nozzles spaced apart on the second water spraying pipe. The second nozzles spray water obliquely downward toward the outside of the discharge end of the second feeding pipe 15. More specifically, the first feeding unit 1a, the second feeding unit 1b, and the tamping mechanism 20 are arranged in sequence along the direction of rotation of the receiving barrel 30. A single material distributing mechanism cannot achieve uniform distribution of the receiving barrel 30 along the radial direction, with either more fiber in the middle than on the sides, or more fiber on the sides than in the middle. Therefore, in this application, two groups of material distributing units are used to form the material distributing mechanism. One group distributes more fiber in the middle and less fiber on the sides, while the other group distributes less fiber in the middle and more fiber on the sides. After the two groups are stacked in sequence, the amount of material in the middle and on the sides tends to be consistent, and then the material is further evenly tamped by the material tamping mechanism 20, thereby achieving uniform fiber distribution without manual assistance, improving production efficiency and reducing costs, as well as ensuring the uniformity of the formed cotton cakes and the reliability of subsequent processing.

[0032] Specifically, the forming tray 11 can be rotatably mounted on the forming base, which is movably mounted horizontally. By adjusting the movement of the forming base, the material receiving bucket 30 filled with cotton fibers can be moved out from under the material distributing mechanism and the material tamping mechanism 20, facilitating the subsequent lifting and transportation of the material receiving bucket 30. Alternatively, the following scheme can be used: the material tamping mounting seat 22 is rotatably mounted on the material tamping sleeve 23 via the A1 rotating shaft, and the material tamping sleeve 23 is slidably mounted on the material tamping column 21, and an A1 regulating cylinder 28 is included to regulate the rotation of the material tamping mounting seat 22 around the A1 rotating shaft. The first distribution pipe 13 includes an A11 pipe section and an A12 pipe section. The A11 pipe section is located on the upper side of the A12 pipe section. The upper end of the A12 pipe section and the lower end of the A11 pipe section are rotatably assembled. The axis of rotation of the A12 pipe section is referred to as the A11 axis, that is, the A12 pipe section is rotatably installed through the A11 axis. The outlet of the A12 pipe section and the A11 axis are eccentrically arranged. The first water spraying mechanism 14 is provided on the A12 pipe section, and the A12 pipe section is connected to the A11 regulating cylinder for adjusting its rotation. The second distributing pipe 15 includes an A21 pipe section and an A22 pipe section. The A21 pipe section is located on the upper side of the A22 pipe section. The upper end of the A22 pipe section is rotatably assembled with the lower end of the A21 pipe section. The axis of rotation of the A22 pipe section is referred to as the A21 axis. That is, the A22 pipe section is rotatably mounted via the A21 axis. The outlet of the A22 pipe section is eccentrically arranged with the A21 axis. The second water spraying mechanism 16 is provided on the A22 pipe section. The A22 pipe section is connected to the A21 regulating cylinder for regulating its rotation. The A1 rotating shaft, the A11 axis, and the A21 axis are all arranged parallel to the centerline of the forming tray 11. In this way, when the amount of cotton fiber received in the receiving barrel 30 reaches a preset amount, the A1 regulating cylinder 28, the A11 regulating cylinder, and the A21 regulating cylinder are activated to adjust the distributing mechanism and the tamping mechanism 20 to move out of the upper side of the receiving barrel 30. Then, the hoisting device is activated to remove the receiving barrel 30 filled with cotton fiber. The first water spray mechanism 14 and the second water spray mechanism 16 have the same structure, and both include an annular water spray pipe and nozzles or spray heads spaced apart on the water spray pipe.

[0033] In summary, the above solution provided by the present invention can effectively improve the uniformity and density of fiber distribution in the prepared cotton cake.

[0034] The above description is merely a preferred embodiment of the present invention.
