Description

Technical Field

[0001] The invention relates to the field of absorbent cotton production, and in particular to a device for cotton fiber molding. 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 molded 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 to a molding barrel that rotates around its central axis through a feeding pipe. After piling up to a corresponding height, the cotton 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 feeding pipe and the extrusion mechanism need to be installed movably to avoid mutual interference. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention. As used herein, the terms "parallel", "vertical", etc. are not limited to their strict mathematical definitions, but include tolerances for machining errors and other reasonable differences.

[0027] like Figures 1 to 8 As shown, a cotton fiber molding device includes a receiving barrel 30 for receiving wet cotton material, the upper part of the receiving barrel 30 has a barrel mouth, the receiving barrel 30 is rotatably mounted on the molding frame and connected to a rotation adjustment mechanism, the rotation adjustment mechanism is used to adjust the receiving barrel 30 to rotate along its vertical center line, 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, and the tamping mechanism 20 and the distributing mechanism are sequentially arranged along the rotation direction of the receiving barrel 30. The wet cotton material entering the barrel is tamped layer by layer by the tamping mechanism 20, so that the cotton material cake formed is more solid and uniform, which is convenient for the uniformity and production efficiency of the subsequent degreasing treatment.

[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 tamped layer by layer, thereby ensuring the reliability of the tamped 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 be lifted, thereby increasing the tamping rate and shortening the time for cotton fiber molding.

[0029] In detail: the tamping mechanism 20 is installed on the tamping mounting seat 22, and the tamping mounting seat 22 is installed on the tamping frame in the vertical direction. The tamping frame is provided with a tamping adjustment mechanism 29 for adjusting the tamping mounting seat 22 to lift and lower. The mounting seat is adjusted to lift and lower by the tamping adjustment mechanism 29, so that as the height of the cotton fiber in the receiving barrel 30 continues to increase, the position of the tamping mechanism 20 is adjusted accordingly to increase the single processing volume of the receiving barrel 30. The lower surface of the tamping block 25 is provided with tamping bumps 26 arranged in a convex shape. Since the surface of the fiber cotton after the cloth is not flat and uniform, the convex parts can be used to further adjust this unevenness and uniformity, improve the uniformity of the cotton cake after forming, and facilitate subsequent further processing. Preferably, two rows of tamping bumps 26 are arranged on the lower surface of the tamping block 25, and the tamping bumps 26 on the two rows are arranged in an interlaced manner. This arrangement is the best way to adjust the uniformity of the cotton fiber and ensure the uniformity of the circumferential arrangement. The two tamping blocks 25 are respectively mounted on the lower ends of the two tamping rods 27, which 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 connected to the tamping motor in a transmission manner, the two output ends of the dual-output reducer 24 are arranged concentrically and transmission cranks are respectively arranged thereon, and the transmission cranks are connected to the upper ends of the tamping rods 27 in a transmission manner 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 tamping operations alternately, thereby ensuring the reliability and efficiency of tamping. The tamping frame includes a forming tray 11 for supporting a material receiving barrel 30 and a tamping column 21 located beside the forming tray 11. The forming tray 11 is rotatably mounted and connected to a forming drive motor for adjusting its rotation. A tamping mounting seat 22 is slidably mounted on the tamping column 21. A tamping adjustment mechanism 29 includes a tamping cylinder or a tamping liquid cylinder connected to the tamping mounting seat 22. The material receiving barrel 30 clamped on the forming tray 11 is adjusted to rotate by the forming drive motor, so that the material receiving barrel 30 can be reliably laid and tamped at all places in the circumference. One end of the tamping cylinder or the tamping liquid cylinder is connected to the tamping mounting seat 22, and the other end is assembled and connected to the tamping column 21. The height of the tamping mechanism 20 is adjusted by the tamping cylinder or the tamping liquid cylinder to match the height of the material in the material receiving barrel 30, so as to ensure the consistency of the strength of the interlayer tamping.

[0030] A further solution is that the upper surface of the forming tray 11 is provided with a first positioning unit and a second positioning unit for assembling the receiving bucket 30, the first positioning unit includes a first boss 12 located in the middle of the upper surface of the forming tray 11, and first positioning plates 18 are radially arranged around the first boss 12, and the second positioning unit includes second bosses located outside the first positioning plates 18, and the second bosses are arranged at intervals along the circumference of the forming tray 11. By providing the first positioning unit and the second positioning unit, the receiving bucket 30 is reliably clamped on the forming 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 along the circumference of 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 device, the cotton fiber air conveying device transports the cotton fiber by air conveying, a first water spraying mechanism 14 for spraying water to the cotton fiber is arranged on the tube 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, and 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 comprises a first feeding unit 1a and a second feeding unit 1b which are arranged at intervals along the circumference of the receiving barrel 30. The second feeding unit 1b comprises a second feeding pipe 15. The discharge end of the second feeding pipe 15 is vertically downward and 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 pointed cone-shaped material stopper 17 is arranged inside the discharge end of the second feeding pipe 15. The material stopper 17 is fixedly mounted on the second feeding pipe 15. A passage for the cotton fiber to pass through is formed between the material stopper 17 and the second feeding pipe 15. A first water spraying mechanism 14 for spraying water to the cotton fiber is arranged on the material stopper 17. The first water spraying mechanism 14 comprises a second annular water spraying pipe. Second nozzles are arranged at intervals on the second water spraying pipe. The water spraying direction of the second nozzle is obliquely downward and points to the outside of the discharge end of the second feeding pipe 15. In more detail, the first feeding unit 1a, the second feeding unit 1b, and the material 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 in the radial direction, either the fiber material in the middle is more than the two sides, or the fiber material in the two sides is more than the middle. Therefore, in the present application, two groups of material distributing units are used to form a distributing mechanism, so that one group of fiber materials is more in the middle and less on the two sides, and the other group of fiber materials is less in the middle and more on the two sides. After the two groups are overlapped in sequence, the amount of material in the middle and on the two sides tends to be consistent, and then the material is further evenly tamped by the tamping mechanism 20, thereby achieving uniform distribution of fibers without manual assistance, improving production efficiency and reducing costs, and 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, and the forming base can be movably mounted in the horizontal direction. By adjusting the movement of the forming base, the receiving barrel 30 filled with cotton fibers can be moved out from under the material distributing mechanism and the tamping mechanism 20, so as to facilitate the subsequent lifting and transportation of the receiving barrel 30. It can also be implemented according to the following scheme, the tamping material mounting seat 22 is rotatably mounted on the tamping material sliding sleeve 23 through the A1 rotating shaft, and the tamping material sliding sleeve 23 is slidably mounted on the tamping material column 21, and also includes an A1 regulating cylinder 28 for adjusting the rotation of the tamping material mounting seat 22 around the A1 rotating shaft. The first material 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 arranged on the A12 pipe section, and the A12 pipe section is connected to the A11 regulating cylinder for adjusting its rotation. The second material 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 and the lower end of the A21 pipe section are rotatably assembled. The axis of rotation of the A22 pipe section is the A21 axis, that is, the A22 pipe section is rotatably installed through the A21 axis. The outlet of the A22 pipe section and the A21 axis are eccentrically arranged. The second water spraying mechanism 16 is arranged on the A22 pipe section. The A22 pipe section is connected to the A21 regulating cylinder for adjusting its rotation. The A1 rotating shaft, the A11 axis, and the A21 axis are all arranged parallel to the center line of the forming tray 11. In this way, when the cotton fiber receiving amount in the material receiving barrel 30 reaches a preset amount, the A1 regulating cylinder 28, the A11 regulating cylinder, and the A21 regulating cylinder are started to adjust the distributing mechanism and the tamping mechanism 20 to move out of the upper side of the material receiving barrel 30, and then the hoisting device is started to move the material receiving barrel 30 filled with cotton fibers away. 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 arranged at intervals on the water spray pipe.

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

[0034] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
