DETAILED DESCRIPTION

[0034] 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.

[0035] like Figures 1 to 3 The device (unloader) for unloading cotton material is shown. The unloading frame includes a barrel clamping mechanism for clamping a receiving barrel 10 and a removal mechanism for removing the cotton cake formed in the receiving barrel 10. The receiving barrel 10 is clamped to the barrel clamping mechanism with the barrel opening facing upward. The barrel clamping mechanism clamps the receiving barrel 10, and the removal mechanism removes or removes the cotton cake from the receiving barrel 10, thereby achieving automated unloading of the cotton cake, improving the production efficiency of absorbent cotton and reducing production costs.

[0036] A further solution is: the unloading frame includes a barrel supporting plate 41 for supporting the receiving barrel 10, and the removing mechanism adopts a jacking method to move the cotton cake out of the receiving barrel 10. Since the receiving barrel 10 is in the shape of a cylinder, the cotton cake is taken out by jacking, and the removal operation is more convenient and simple. Specifically, the removing mechanism can be set on the barrel supporting plate 41. The removing mechanism includes a lifting rod 4b movably installed in the vertical direction, the barrel supporting plate 41 is circular, and the lifting rods 4b are evenly spaced along the circumference of the barrel supporting plate 41. The top of the lifting rod 4b extends from the bottom of the receiving barrel 10 into the receiving barrel 10 to lift the cotton cake. Using multiple lifting rods 4b to lift and unload the cotton cake makes the cotton cake more stable during the lifting and unloading process, and thus does not cause the material to get stuck. The unloading frame also includes support columns 40 positioned outside a barrel support plate 41, which is fixedly mounted on the support columns 40. The barrel clamping mechanism includes clamping subunits mounted on each support column 40. Due to the large size of the receiving barrel 10, multiple clamping subunits are provided to clamp different parts of the receiving barrel 10, improving the reliability of the clamping operation, preventing the receiving barrel 10 from coming loose during the lifting and unloading process, and enhancing the reliability of the unloading process.

[0037] like Figure 2 、 3 As shown, the clamping subunit includes a clamping hook 45, the middle portion of which is hingedly mounted on the support column 40 via a clamping hinge axis. The clamping hinge axis is arranged horizontally and perpendicular to the radial direction of the barrel support plate 41. The upper end of the clamping hook 45 is provided with a hook body, and the lower end of the clamping hook 45 is connected to a clamping adjustment cylinder 44. The clamping adjustment cylinder 44 adjusts the clamping hook 45 between two states: one is that the hook body of the clamping hook 45 is tilted to the outside of the receiving barrel 10 to avoid the vertical movement of the barrel 10; the other is that the clamping hook 45 is tilted inward to hook and engage the mounting protrusions provided on the barrel wall of the receiving barrel 10. By hooking and engaging the mounting protrusions provided on the receiving barrel 10 and supporting the barrel support plate 41, the vertical movement of the receiving barrel 10 is constrained, thereby preventing the removal mechanism from lifting the barrel body together, and switching between clamping and releasing operations is convenient and fast. The support column 40 is also provided with a guide mechanism for aligning the assembly protrusions with the clamping hooks 45. The guide mechanism ensures that the assembly protrusions and the clamping hooks 45 are aligned with each other during the falling process of the receiving bucket 10, so that the receiving bucket 10 can be accurately positioned and the hoisting error of the hoisting equipment can be avoided, which may cause the assembly protrusions and the clamping hooks 45 to be misaligned.

[0038] Detailed: The support column 40 is provided with a support platform 49 for supporting the bottom edge of the barrel 10, and a clamping mounting hole 46 is provided on the support column 40 on the upper side of the support platform 49. The clamping hook 45 is installed at the clamping mounting hole 46. The guide mechanism includes a first guide plate 47 and a second guide plate 48 provided on both sides of the clamping mounting hole 46. The first guide plate 47 and the second guide plate 48 are provided on the outer cylindrical surface of the support column 40. The first guide plate 47 is composed of a long strip plate body, and the second guide plate 48 is composed of a folded plate body. The first guide plate 47 and the second guide plate The lower end of 48 is arranged in a flush shape. The length of the first guide plate 47 is greater than that of the second guide plate 48. The second guide plate 48 is composed of a plate body A and a plate body B. The plate body A is located on the lower side of the plate body B. The distance between the plate body A and the first guide plate 47 remains unchanged from bottom to top. The hook body is arranged corresponding to the plate body A. The distance between the plate body B and the first guide plate 47 gradually increases from bottom to top. The height of the first guide plate 47 protruding from the outer cylindrical surface of the material support column 40 gradually increases from top to bottom. The first guide plate 47 and the second guide plate 48 are used to guide and position the assembly protrusion. That is, the first guide plate 47 and the second guide plate 48 are vertically installed on the outer cylindrical surface of the material support column 40. During the falling process of the receiving bucket 10, the first guide plate 47 and the second guide plate 48 guide the material receiving bucket 10 to rotate, so that the assembly protrusion on the receiving bucket 10 is accurately positioned. The guide mechanism also includes a third guide member disposed at the top of the support column 40. This third guide member has a third guide slope, which is arranged parallel to the clamping hinge axis. The spacing between the third guide slope and the centerline of the barrel support plate 41 gradually increases from top to bottom, and the lower side of the third guide slope is flush with the outer cylindrical surface of the support column 40. The third guide member and the other guide members coordinate to ensure that the receiving barrel 10 can be accurately positioned on the discharge frame and accurately centered when it is lowered. A lifting adjustment plate 42 is provided on the lower side of the barrel support plate 41. The lower end of each ejector rod 4b is fixedly connected to the lifting adjustment plate 42. The middle portion of the lifting adjustment plate 42 is connected to the lifting adjustment hydraulic cylinder 43 / lifting adjustment cylinder. Specifically, the hydraulic cylinder 43 is installed upside down, with the lower end of the cylinder body of the hydraulic cylinder 43 fixedly connected to the lifting plate 42. A recess is provided in the middle of the barrel support plate 41 for the cylinder body to pass through, and the lower end of the piston rod of the hydraulic cylinder 43 is fixedly connected to the frame, thereby achieving synchronous lifting and adjusting of each ejector rod 4b. A cushion 4a is provided on the support platform 49. This cushion 4a cushions the drop of the receiving barrel 10, preventing hard impact, protecting the receiving barrel 10 and the unloading device, and extending its service life.

[0039] In summary, the above-mentioned unloading machine provided by the present invention can effectively and quickly and conveniently unload the cotton cakes in the docking barrel 10, thereby improving the production efficiency of the absorbent cotton and reducing labor intensity.

[0040] The present invention also provides a production process and system for absorbent cotton, which improves upon the conventional absorbent cotton production line and process, specifically the "forming → degreasing → cake forming → dehydration" stages. Therefore, in addition to the equipment described herein, the present invention may also include a plucker, a cotton opener, a fine opener, a carding machine, and the like, which are sequentially arranged. The plucker, cotton opener, fine opener, and carding machine are implemented in accordance with the existing absorbent cotton production line. The cotton fibers produced in the preceding stages are transported to the forming machine via an air conveyor for subsequent processing.

[0041] The absorbent cotton production system for the production process includes a material receiving barrel, a forming machine, a degreasing machine, a cotton material unloading device, a dehydrator, an opener, and a dryer. The material receiving barrel, the forming machine, and the cotton material unloading device are implemented according to the scheme described in this application, and the degreasing machine, the dehydrator, the opener, and the dryer can be implemented according to existing schemes.

[0042] like Figures 4 to 8 As shown, the receiving barrel 10 includes a barrel body, which is open-mouthed. A vertically arranged intermediate column 15 is provided in the middle of the barrel body. An annular distribution area for arranging cotton fibers is formed between the intermediate column 15 and the barrel wall 11 of the barrel body. A liquid guide structure is provided on the barrel wall 11 of the barrel body. The liquid guide structure is used to allow liquid to enter and exit the barrel body. The barrel body is also provided with a hoisting structure and a clamping mechanism. The hoisting structure is used to lift the barrel body, and the clamping structure is used to meet the clamping requirements for adjusting the barrel body to rotate around its center line. Through the provision of the distribution area, the wet fibers are reliably and continuously received, and at the same time, they are formed into a cake shape in the distribution area. The liquid guide structure allows the alkali solution to enter the barrel body well to degrease the cotton fibers. The hoisting structure allows the receiving barrel 10 to be reliably and conveniently transferred between various processes. The clamping mechanism is used to ensure that when the cotton fiber cake is formed, the cotton fiber can be accurately and reliably distributed evenly and reliably throughout the annular distribution area on the receiving barrel 10, thereby meeting the degreasing requirements of the cotton thread.

[0043] The specific solution is as follows: the barrel wall 11 of the barrel body is composed of a barrel wall 11 skeleton and a barrel wall 11 mesh body laid on the barrel wall 11 skeleton, and the mesh holes on the barrel wall 11 mesh body constitute the liquid guide structure. The barrel wall 11 of the barrel body is set as a mesh structure, so that the alkali solution can quickly enter the barrel body to soak the cotton fibers, thereby improving the efficiency and reliability of the cotton fiber degreasing treatment. The outer contour of the barrel body is cylindrical. The barrel body is set as a cylindrical barrel body, which makes it more convenient to feed the material into the barrel body, so that the cotton fibers can be more evenly distributed in the cross-sectional area of ​​the barrel body. The lifting structure includes a transfer lug 16 and a lifting screw 17 arranged at the top of the intermediate column 15. The transfer lug 16 is provided with a lifting nut, and the lifting nut and the lifting screw 17 are detachably assembled and connected. Through the lifting structure composed of the lifting nut and the lifting screw 17, when the receiving barrel 10 needs to be lifted, the transfer lifting ear 16 can be assembled on the lifting screw 17. When lifting is not required and other operations are to be performed, the transfer lifting ear 16 is first removed, and then other operations are performed, thereby simplifying the operation.

[0044] like Figure 5 As shown, the barrel bottom 12 of the barrel body is formed of a circular plate, and the clamping mechanism includes first positioning holes 14 provided on the barrel bottom 12. The first positioning holes 14 are provided at intervals in the circumferential direction of the barrel bottom 12 and are provided adjacent to the edge of the barrel bottom 12. The provision of the first positioning holes 14 is mainly used to limit the circumferential rotation of the barrel body and to ensure that the receiving barrel 10 can be accurately positioned during clamping. An assembly protrusion 13 is provided on the outer wall surface of the barrel wall 11 of the barrel body. The assembly protrusion 13 is provided on the bottom of the barrel wall of the barrel body and is evenly spaced along the circumference of the barrel body. By providing the assembly protrusion 13, the height direction of the barrel body is clamped and restricted, which facilitates the removal of the degreased cotton cake from the receiving barrel 10. The thickness of the assembly protrusion 13 protruding from the barrel wall 11 of the barrel body gradually increases from bottom to top. The assembly protrusion 13 is set to a structure with gradually increasing thickness, which facilitates the falling guidance of the material receiving bucket 10. The material receiving bucket 10 can be accurately positioned during assembly, thereby improving the convenience of the assembly operation.

[0045] like Figure 4As shown, the barrel body's bottom 12 is formed of an annular base plate, while the intermediate column 15 is cylindrical. This column 15 comprises a column frame and an intermediate mesh mounted on the frame. The frame is fixedly mounted to the inner edge of the annular base plate. The upper surface of the intermediate column 15 comprises an intermediate top plate, with a mounting screw 17 fixedly mounted in the middle of the top plate. Reinforcing ribs are radially arranged on the lower surface of the annular base plate. This structure of the intermediate column 15 allows the degreasing alkali solution to enter the intermediate column 15 through the opening in the middle of the annular base plate, then penetrate through the intermediate mesh into the cotton cake, thereby degreasing the cotton fibers and ensuring the effective soaking effect.

[0046] like Figure 6 、 7 As shown, the auxiliary baffles 18 are also included. The auxiliary baffles 18 are composed of arc-shaped plates with evenly distributed through holes. The auxiliary baffles 18 enclose an annular auxiliary material storage portion. The annular auxiliary material storage portion and the barrel body are detachably connected by connecting clips 19 provided on the lower edges of the auxiliary baffles 18. In this way, by providing the auxiliary baffles 18, it is possible to adapt to the requirements of receiving materials of different specifications. During normal material receiving, the auxiliary baffles 18 can be removed and not used. When the material receiving capacity needs to be increased, the auxiliary baffles 18 can be installed on the upper edge of the barrel body to form an annular auxiliary material storage portion, thereby increasing the material receiving capacity and meeting different requirements. The disassembly and installation are also convenient.

[0047] like Figure 8 As shown, the apparatus also includes an annular net bag 1a. Slings 1c are evenly spaced around its outer periphery. One end of each sling 1c is fixedly connected to the annular net bag 1a, and the other end of each sling 1c is provided with a buckle 1b. The annular net bag 1a is primarily intended to facilitate the transport of discharged cotton cakes. Before the material receiving and forming operations, the annular net bag 1a is first laid on the bottom 12 of the material receiving barrel 10. The sling 1c is then passed around the barrel opening of the material receiving barrel 10, with the other end of the sling 1c secured to the outer barrel wall 11 of the material receiving barrel 10 via a tying wire. After the cotton cakes are ejected from the material receiving barrel 10, the tying wire is released, and the buckle 1b at the other end of the sling 1c is hooked onto a lifting hook. The lifting device is then activated to lift the cotton cakes into the dehydrator for dehydration. The apparatus also includes an annular movable support plate 1d, which is loosely mounted on the intermediate column 15. The annular movable support plate 1d is provided primarily to facilitate unloading of the degreased cotton cake from the barrel body. During unloading, the annular movable support plate 1d is lifted to remove the cotton cake from the barrel body. Prior to the material receiving and forming operations, the annular net bag 1a is placed on the annular movable support plate 1d within the receiving barrel 10. A movable pressure cap may also be included to hold the absorbent cotton in place during the degreasing process.

[0048] The material receiving barrel 10 provided by the present invention can effectively ensure the shaping and degreasing of cotton fibers and facilitate the transportation of cotton fibers.

[0049] like Figures 9 to 16 As shown, the forming machine includes a receiving barrel 10 for receiving wet cotton material. The upper part of the receiving barrel 10 has a barrel mouth. The receiving barrel 10 is rotatably mounted on the forming machine frame and connected to a rotation adjustment mechanism. The rotation adjustment mechanism is used to adjust the rotation of the receiving barrel 10 along its vertical center line. The upper side of the receiving barrel 10 is provided with a distributing mechanism for distributing wet cotton material into the receiving barrel 10, and a tamping mechanism 30 for tamping the wet cotton material in the receiving barrel 10 layer by layer. The tamping mechanism 30 and the distributing mechanism are sequentially arranged along the rotation direction of the receiving barrel 10. The wet cotton material entering the barrel is tamped layer by layer by the tamping mechanism 30, 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 process.

[0050] A further solution is, Figure 9 、 11 As shown: the receiving barrel 10 has an annular material distribution area, and the tamping mechanism 30 includes a tamping block 35 and a vertical adjustment component radially arranged in the material distribution area along the receiving barrel 10. The tamping block 35 is movably installed in the vertical direction, and the vertical adjustment component is used to adjust the movement of the tamping block 35 in the vertical direction. By adjusting the vertical movement of the tamping block 35, the material on the lower side is tamped layer by layer, thereby ensuring the reliability of the tamping material. A plurality of tamping blocks 35 are arranged at circumferential intervals along the receiving barrel 10. Preferably, two tamping blocks 35 are arranged at circumferential intervals along the receiving barrel 10, and the vertical adjustment component adjusts the two tamping blocks 35 to be staggered and lifted. By setting two tamping blocks 35, when one tamping block 35 descends to tamping material, the other tamping block 35 is adjusted to lift, thereby increasing the tamping rate and shortening the time for cotton fiber molding.

[0051] In detail: The tamping mechanism 30 is mounted on a tamping mounting seat 32, which is vertically mounted on a tamping frame. The tamping frame is provided with a tamping adjustment mechanism 39 for adjusting the tamping mounting seat 32 for elevation. The tamping adjustment mechanism 39 adjusts the mounting seat for elevation. As the height of the cotton fibers within the receiving barrel 10 increases, the position of the tamping mechanism 30 is adjusted accordingly, thereby increasing the single-time processing capacity of the receiving barrel 10. The lower surface of the tamping block 35 is provided with rammed material bumps 36, each arranged in a raised manner. Because the surface of the fiber cotton after being laid is not flat and uniform, the provided raised portions can further adjust this unevenness and uniformity, improving the uniformity of the formed cotton cake and facilitating subsequent further processing. Preferably, two rows of ramming material bumps 36 are provided on the lower surface of the tamping block 35, with the ramming material bumps 36 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 35 are respectively mounted on the lower ends of the two tamping rods 37. The two tamping rods 37 are arranged vertically and slidably mounted on the tamping mounting seat 32 in the vertical direction. The vertical adjustment assembly includes a dual-output reducer 34 mounted on the tamping mounting seat 32. The input end of the dual-output reducer 34 is connected to the tamping motor in a transmission manner. The two output ends of the dual-output reducer 34 are concentrically arranged and provided with transmission cranks respectively. The transmission cranks are connected to the upper ends of the tamping rods 37 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 35 to perform the tamping operation alternately, thereby ensuring the reliability and efficiency of the tamping. The tamping frame includes a forming tray 21 for supporting the material receiving barrel 10 and a tamping column 31 located next to the forming tray 21. The forming tray 21 is rotatably mounted and connected to a forming drive motor that adjusts its rotation. A tamping mounting seat 32 is slidably mounted on the tamping column 31. A tamping adjustment mechanism 39 includes a tamping cylinder or a tamping liquid cylinder connected to the tamping mounting seat 32. The forming drive motor is used to adjust the rotation of the material receiving barrel 10 clamped on the forming tray 21, so that the material can be reliably distributed and tamped at all locations around the material receiving barrel 10. One end of the tamping cylinder or the tamping liquid cylinder is connected to the tamping mounting seat 32, and the other end is assembled and connected to the tamping column 31. The height of the tamping mechanism 30 is adjusted by the tamping cylinder or the tamping liquid cylinder to match the height of the material in the material receiving barrel 10, ensuring that the strength of the interlayer tamping is consistent.

[0052] A further solution is to provide a first positioning unit and a second positioning unit on the upper surface of the forming tray 21 for assembling the receiving bucket 10. The first positioning unit includes a first boss 22 located in the middle of the upper surface of the forming tray 21, with first positioning plates 28 radially arranged around the first boss 22. The second positioning unit includes second bosses located outside the first positioning plates 28, and the second bosses are spaced apart along the circumference of the forming tray 21. The first and second positioning units ensure that the receiving bucket 10 is securely clamped to the forming tray.

[0053] A more preferred embodiment is as follows Figure 14 、 15 , 16: The feeding mechanism includes a first feeding unit 2a and a second feeding unit 2b which are spaced apart circumferentially along the receiving barrel 10, the first feeding unit 2a includes a first feeding pipe 23, the discharge end of the first feeding pipe 23 is vertically downward and arranged corresponding to the feeding area, the feed end of the first feeding pipe 23 is connected to the cotton fiber air conveying equipment, and the cotton fiber air conveying equipment transports cotton fibers by air conveying, and a first water spraying mechanism 24 for spraying water to the cotton fibers is provided on the pipe wall of the discharge end of the first feeding pipe 23, the first water spraying mechanism 24 includes a first annular water spraying pipe, and 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 part of the discharge end of the first feeding pipe 23. The feeding mechanism includes a first feeding unit 2a and a second feeding unit 2b spaced apart along the circumference of the receiving barrel 20. The second feeding unit 2b includes a second feeding pipe 25, the discharge end of which faces vertically downward and is arranged corresponding to the feeding area. The feed end of the second feeding pipe 25 is connected to the cotton fiber air conveying device. A conical material stopper 27 is provided inside the discharge end of the second feeding pipe 25. The stopper 27 is fixedly mounted on the second feeding pipe 25, forming a channel for the cotton fiber to pass through. The stopper 27 is provided with a first water spraying mechanism 24 for spraying water on the cotton fiber. The first water spraying mechanism 24 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 25. More specifically, the first feeding unit 2a, the second feeding unit 2b, and the tamping mechanism 30 are arranged in sequence along the direction of rotation of the receiving barrel 10. A single cloth distributing mechanism cannot achieve uniform distribution of the receiving barrel 10 along the radial direction, and either there is more fiber in the middle than on both sides, or there is more fiber on both sides than in the middle. Therefore, in this application, two groups of cloth distributing units are used to form the cloth distributing mechanism. One group distributes more fiber in the middle and less on both sides, while the other group distributes less fiber in the middle and more on both sides. After the two groups are superimposed in sequence, the amount of material in the middle and on both sides tends to be consistent, and then the material is further evenly tamped by the tamping mechanism 30, thereby achieving uniform distribution of fibers without the need for 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.

[0054] Specifically, the forming tray 21 can be rotatably mounted on the forming base, which is movably mounted horizontally. By adjusting the movement of the forming base, the receiving bucket 20 filled with cotton fibers can be moved out from under the material distributing mechanism and the tamping mechanism 30, facilitating the subsequent lifting and transportation of the receiving bucket 10. Alternatively, the following scheme can be used: the tamping material mounting seat 32 is rotatably mounted on the tamping material sliding sleeve 33 via the A1 rotating shaft, and the tamping material sliding sleeve 33 is slidably mounted on the tamping material column 31, and an A1 regulating cylinder 38 is also included to regulate the rotation of the tamping material mounting seat 32 around the A1 rotating shaft. The first distribution pipe 23 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 24 is provided on the A12 pipe section, and the A12 pipe section is connected to the A11 regulating cylinder that adjusts its rotation. The second distributing pipe 25 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 26 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 21. In this manner, when the cotton fiber receiving amount in the receiving barrel 10 reaches a preset amount, the A1 regulating cylinder 38, the A11 regulating cylinder, and the A21 regulating cylinder are activated to adjust the distributing mechanism and the tamping mechanism 30 to move out of the upper side of the receiving barrel 10. Then, the hoisting device is activated to remove the receiving barrel 10 filled with cotton fiber. The first water spray mechanism 24 and the second water spray mechanism 26 have the same structure, and both include an annular water spray pipe and nozzles or spray heads spaced apart on the water spray pipe.

[0055] The molding machine provided above can effectively improve the uniformity and density of fiber distribution in the prepared cotton cake.

[0056] The production process of absorbent cotton using the above system is as follows: a receiving barrel is assembled on a forming machine. Before feeding the barrel, a circular movable support plate is installed and a circular net bag is placed on the support plate. A sling is attached to the outer edge of the net bag, which is passed around the barrel opening. The other end of the sling is secured to the outer wall of the barrel with a wire tie. The forming machine is started, and cotton fibers are fed into the barrel via a material distribution mechanism. The fibers are wetted as they fall. The barrel on the forming machine is adjusted to rotate about its centerline to lay the fibers layer by layer. After the wet fibers are laid, two tamping blocks alternately tamp the fibers to compact them layer by layer. When a predetermined amount of cotton fibers has been added, a transfer lug is attached to the lifting screw on the barrel. The transfer hook on the crane hoisting device is activated to engage the transfer lug and lift the barrel into the degreasing machine for degreasing. After degreasing is complete, the transfer lugs are assembled on the receiving barrel's lifting screws. The transfer hooks on the overhead crane are activated, cooperating with the transfer lugs to lift the barrel into the discharger for unloading. During the barrel clamping process, the guide mechanism ensures the barrel is accurately positioned on the discharger frame. The barrel clamping mechanism is then activated to secure the barrel, and the removal mechanism pushes the degreased cotton cake out of the barrel. After the cotton cake is pushed out of the barrel, the ties are loosened, and the buckle hooks on the other ends of each tie are attached to the transfer hooks on the overhead crane. The overhead crane is then activated to lift the cotton cake into the dehydrator for dehydration.

[0057] The technical solution provided by the utility model can effectively reduce the labor intensity in the production process of absorbent cotton, improve production efficiency and reduce production costs.
