DETAILED DESCRIPTION

[0034] 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.

[0035] like Figures 1 to 3 As shown, a device (unloader) for unloading cotton material comprises a unloading frame, on which 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 are arranged, and the receiving barrel 10 is clamped on the barrel clamping mechanism with the barrel opening facing upward. The receiving barrel 10 is clamped by the barrel clamping mechanism, and then the cotton cake in the receiving barrel 10 is taken out or removed by the removal mechanism, thereby realizing the automatic unloading of the cotton cake, improving the production efficiency of the absorbent cotton and reducing the production cost.

[0036] A further solution is: the unloading frame includes a barrel support plate 41 for supporting the receiving barrel 10, and the removal mechanism adopts a lifting method to move the cotton cake out of the receiving barrel 10. Since the receiving barrel 10 is in the shape of a round barrel, the cotton cake is taken out by lifting, and the removal operation is more convenient and simple. Specifically, the removal mechanism can be set on the barrel support plate 41. The removal mechanism includes a lifting rod 4b movably installed in the vertical direction, the barrel support plate 41 is circular, and the lifting rod 4b is evenly spaced along the circumference of the barrel support 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. A plurality of lifting rods 4b are used to lift and unload the cotton cake, so that the cotton cake is more stable during the lifting and unloading process, and the phenomenon of material jamming will not occur. The unloading frame also includes supporting columns 40 arranged outside the barrel supporting plate 41, the barrel supporting plate 41 is fixedly mounted on the supporting columns 40, and the barrel clamping mechanism includes clamping subunits respectively arranged on the supporting columns 40. Since the size of the receiving barrel 10 is relatively large, a plurality of clamping subunits are provided to clamp different parts of the receiving barrel 10 respectively, thereby improving the reliability of the clamping operation, avoiding the phenomenon of the receiving barrel 10 being loosened during the lifting and unloading process, and improving the reliability of unloading.

[0037] like Figure 2 , 3 As shown, the clamping subunit includes a clamping hook 45, the middle part of which is hingedly mounted on the support column 40 through a clamping hinge shaft, the clamping hinge shaft is arranged horizontally and perpendicular to the radial direction of the barrel support plate 41, a hook body is arranged at the upper end of the clamping hook 45, and the lower end of the clamping hook 45 is connected to a clamping adjustment cylinder 44, and the clamping adjustment cylinder 44 adjusts the clamping hook 45 to be in two states, one of which is: the hook body of the clamping hook 45 is turned over to the outside of the receiving barrel 10 to avoid the movement of the connecting barrel 10 in the vertical direction, and the other is: the clamping hook 45 is turned over inward to hook and pull the assembly protrusion arranged on the barrel wall of the connecting barrel 10. Through the hooking and pulling of the assembly protrusion on the connecting barrel 10 by the clamping hook 45 and the support of the barrel support plate 41, the vertical movement of the connecting barrel 10 is restricted, thereby preventing the removal mechanism from lifting the barrel body together, and the switching of the clamping and loosening operations is convenient and fast. A guide mechanism is also provided on the support column 40, and the guide mechanism is used to arrange the assembly protrusion and the clamping hook 45 in correspondence. The guide mechanism is provided so that the assembly protrusion and the clamping hook 45 are arranged in correspondence 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 so that the assembly protrusion and the clamping hook 45 cannot be aligned.

[0038] In detail: the support column 40 is provided with a support platform 49 for supporting the bottom edge of the barrel 10, and the support column 40 on the upper side of the support platform 49 is provided with a clamping installation hole 46, and the clamping hook 45 is installed at the clamping installation hole 46. The guide mechanism includes a first guide plate 47 and a second guide plate 48 arranged on both sides of the clamping installation hole 46. The first guide plate 47 and the second guide plate 48 are arranged 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. 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 the length 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 support column 40 gradually increases from top to bottom, and 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 support column 40, and during the falling process of the receiving barrel 10, the first guide plate 47 and the second guide plate 48 are used to adjust the rotation of the receiving barrel 10, so that the assembly protrusion on the receiving barrel 10 is accurately positioned. The guide mechanism also includes a third guide member arranged at the top of the support column 40, and the third guide member has a third guide slope, which is arranged parallel to the clamping hinge axis, and the distance between the third guide slope and the center line 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. Through the guiding cooperation of the third guide member and other guide members, the receiving barrel 10 can be accurately positioned on the unloading frame and accurately fall in the center. A lifting adjustment plate 42 is arranged on the lower side of the barrel support plate 41, and the lower end of each ejector rod 4b is fixedly connected to the lifting adjustment plate 42, and the middle part of the lifting adjustment plate 42 is connected to the lifting adjustment hydraulic cylinder 43 / lifting adjustment cylinder. Specifically, the lifting and adjusting hydraulic cylinder 43 can be installed upside down, the lower end of the cylinder body of the lifting and adjusting hydraulic cylinder 43 is fixedly connected to the lifting and adjusting plate 42, a vacant portion for the cylinder body to pass through is provided in the middle of the barrel support plate 41, and the lower end of the piston rod of the lifting and adjusting hydraulic cylinder 43 is fixedly connected to the frame, so as to achieve synchronous lifting and adjusting of each ejecting rod 4b. A buffer pad 4a is provided on the support platform 49. The buffer pad 4a is provided to buffer the fall of the docking barrel 10, avoid hard collision, protect the receiving barrel 10 and the unloading device, and extend the service life.

[0039] In summary, the above-mentioned unloading machine provided by the present invention can effectively unload the cotton cakes in the docking barrel 10 quickly and conveniently, 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 is an improvement on the traditional absorbent cotton production line and production process, and is an improvement on the "molding→degreasing→cake-forming→dehydration" section therein. Therefore, in addition to the equipment recorded in the text of the present invention, it can also include a cotton plucker, a cotton opener, a fine cotton opener, a cotton combing machine, etc. arranged in sequence. The cotton plucker, the cotton opener, the fine cotton opener, and the cotton combing machine are implemented according to the existing absorbent cotton production line. The cotton fibers produced in the front section are transported to the molding machine through the air conveying device for subsequent processing.

[0041] The absorbent cotton production system used in the production process includes a material receiving barrel, a forming machine, a degreasing machine, a cotton material unloading device, a dehydrating machine, an opener and a drying machine. The material receiving barrel, the forming machine and the cotton material unloading device are implemented according to the scheme recorded in this application, and the degreasing machine, the dehydrating machine, the opener and the drying machine can be specifically implemented according to the existing scheme.

[0042] like Figures 4 to 8 As shown, the receiving barrel 10 includes a barrel body, which is open-mouthed. A middle column 15 arranged vertically is provided in the middle of the barrel body. An annular cloth area for arranging cotton fibers is formed between the middle 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 realize the hoisting of 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 provided cloth area, the wet fibers are reliably and continuously received, and at the same time, they are made into a cake shape in the cloth 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 in all parts of the annular distribution area on the receiving barrel 10, thereby meeting the degreasing requirements of the cotton thread.

[0043] The specific scheme 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 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 ear 16 and a lifting screw 17 arranged at the top of the intermediate column 15, and the transfer ear 16 has 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 material 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 composed of a circular plate body, and the clamping mechanism includes a first positioning hole 14 arranged on the barrel bottom 12, and the first positioning hole 14 is arranged at intervals in the circumferential direction of the barrel bottom 12 and is arranged adjacent to the edge of the barrel bottom 12. The first positioning hole 14 is mainly used to limit the circumferential rotation of the barrel body and ensure that the receiving barrel 10 can be accurately positioned when clamped. An assembly protrusion 13 is arranged on the outer wall surface of the barrel wall 11 of the barrel body, and the assembly protrusion 13 is arranged at the bottom of the barrel wall of the barrel body. The assembly protrusion 13 is evenly spaced along the circumference of the barrel body. By setting the assembly protrusion 13, the clamping restriction of the barrel body in the height direction is achieved, 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 is convenient for guiding the material receiving bucket 10 to fall down, so that the material receiving bucket 10 can be accurately positioned during assembly, thereby improving the convenience of assembly operation.

[0045] like Figure 4As shown: the barrel bottom 12 of the barrel body is composed of an annular bottom plate, the middle column 15 is cylindrical, the middle column 15 includes a column frame and an intermediate mesh body laid on the column frame, the column frame is fixedly installed at the inner ring edge of the annular bottom plate, the upper surface of the middle column 15 is composed of an intermediate top plate, the lifting screw 17 is fixedly installed in the middle of the intermediate top plate, and various reinforcing ribs are radially arranged on the lower surface of the annular bottom plate. The middle column 15 of the above structure allows the degreasing alkali solution to enter the middle column 15 from the mouth in the middle of the annular bottom plate, and then penetrate into the cotton cake through the middle mesh body, thereby degreasing the cotton fibers and ensuring the effect of the immersion.

[0046] like Figure 6 , 7 As shown: it also includes auxiliary baffles 18, which are composed of arc-shaped plates, and through holes are evenly provided on the arc-shaped plates. The auxiliary baffles 18 enclose an annular auxiliary material storage part, and the annular auxiliary material storage part and the barrel body are detachably assembled and connected through the connecting buckle 19 provided at the lower edge of the auxiliary baffle 18. In this way, by providing the auxiliary baffles 18, it is possible to meet the requirements of receiving materials of different specifications. When receiving materials normally, the auxiliary baffles 18 can be removed and not used. When the amount of receiving materials needs to be increased, the auxiliary baffles 18 can be assembled on the upper edge of the barrel body to form an annular auxiliary material storage part, so as to increase the amount of receiving materials and meet different requirements, and the disassembly and installation are convenient.

[0047] like Figure 8 As shown: it also includes an annular net bag 1a, and each sling 1c is evenly spaced on the outer periphery of the annular net bag 1a. One end of the sling 1c is fixedly connected to the annular net bag 1a, and the other end of the sling 1c is provided with a buckle 1b. The purpose of setting the annular net bag 1a is mainly to facilitate the transportation of the unloaded cotton cakes. Before the material receiving and forming operation, the annular net bag 1a is first laid on the barrel bottom 12 of the material receiving barrel 10, and then the sling 1c is passed around the barrel mouth of the material receiving barrel 10, so that the other end of the sling 1c is fixed to the outer barrel wall 11 of the material receiving barrel 10 through a wire tie. After the cotton cakes in the material receiving barrel 10 are ejected, the wire tie is loosened, and the buckle 1b at the other end of the sling 1c is hooked on the hook, and the hoisting device is started to hoist the cotton cakes into the dehydrator for dehydration. It also includes an annular movable support plate 1d, and the annular movable support plate 1d is empty on the middle column 15. The annular movable support plate 1d is provided mainly to facilitate the unloading of the cotton cake after degreasing treatment in the barrel body. When unloading, the cotton cake is moved out of the barrel body by lifting the annular movable support plate 1d. Before the material receiving and forming operation, the annular net bag 1a is laid on the annular movable support plate 1d in the material receiving barrel 10. It can also include a movable pressure cover, which can be used to press the absorbent cotton during degreasing treatment.

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

[0049] like Figures 9 to 16 As shown, the molding 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 molding machine frame and connected to a rotation adjustment mechanism, the rotation adjustment mechanism is used to adjust the receiving barrel 10 to rotate 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, and 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 treatment.

[0050] A further solution is, Fig. 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 tamped 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 is lowered to tamping material, the other tamping block 35 is adjusted to be lifted, thereby increasing the tamping rate and shortening the time for cotton fiber molding.

[0051] In detail: the tamping mechanism 30 is installed on the tamping mounting seat 32, and the tamping mounting seat 32 is installed on the tamping frame in the vertical direction. The tamping frame is provided with a tamping adjustment mechanism 39 for adjusting the tamping mounting seat 32 to rise and fall. The mounting seat is adjusted to rise and fall by the tamping adjustment mechanism 39, so that as the height of the cotton fiber in the receiving barrel 10 continues to increase, the position of the tamping mechanism 30 is adjusted accordingly to increase the single processing volume of the receiving barrel 10. The lower surface of the tamping block 35 is provided with tamping bumps 36 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 36 are arranged on the lower surface of the tamping block 35, and the tamping bumps 36 on the two rows are arranged in an interlaced manner. This arrangement is the best for adjusting the uniformity of the cotton fiber and ensuring the uniformity of the circumferential arrangement. The two tamping blocks 35 are respectively mounted on the lower ends of the two tamping rods 37, which 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 arranged concentrically and transmission cranks are respectively arranged thereon, and 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 tamping operations alternately, thereby ensuring the reliability and efficiency of tamping. The tamping frame includes a forming tray 21 for supporting the material receiving barrel 10 and a tamping column 31 located beside the forming tray 21. The forming tray 21 is rotatably installed and connected to a forming drive motor for adjusting its rotation. A tamping mounting seat 32 is slidably installed 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 material receiving barrel 10 clamped on the forming tray 21 is adjusted to rotate by the forming drive motor, so that the material receiving barrel 10 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 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, so as to ensure the consistency of the strength of the interlayer tamping.

[0052] A further solution is that the upper surface of the forming tray 21 is provided with a first positioning unit and a second positioning unit 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, and first positioning plates 28 are arranged radially around the first boss 22, and the second positioning unit includes second bosses located outside the first positioning plates 28, and the second bosses are arranged at intervals along the circumference of the forming tray 21. By providing the first positioning unit and the second positioning unit, the receiving bucket 10 is reliably clamped on the forming tray.

In more detail, the first feeding unit 2a, the second feeding unit 2b, and the material tamping mechanism 30 are arranged in sequence along the direction of rotation of the receiving barrel 10. A single material distributing mechanism cannot achieve uniform distribution of the receiving barrel 10 in the radial direction, either more in the middle than on the two sides, or more on the two sides than in the middle. Therefore, in the present application, two groups of material distributing units are used to form a material distributing mechanism, one group distributing more fiber material in the middle and less on the two sides, and the other group distributing less fiber material 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 material tamping mechanism 30, 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.

[0054] Specifically, the forming tray 21 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 20 filled with cotton fibers can be moved out from under the material distributing mechanism and the material tamping mechanism 30, which is convenient for the subsequent lifting and transportation of the receiving barrel 10. It can also be implemented according to the following scheme, the tamping material mounting seat 32 is rotatably mounted on the tamping material sliding sleeve 33 through the A1 rotating shaft, and the tamping material sliding sleeve 33 is slidably mounted on the tamping material column 31, and also includes an A1 regulating cylinder 38 for adjusting the rotation of the tamping material mounting seat 32 around the A1 rotating shaft. The first material 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 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 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 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 26 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 21. In this way, 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 started to adjust the distributing mechanism and the tamping mechanism 30 to move out of the upper side of the receiving barrel 10, and then the hoisting device is started to move the receiving barrel 10 filled with cotton fibers away. 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 arranged at intervals 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 operation of producing absorbent cotton by using the above system is as follows: assemble the receiving barrel on the forming machine, and before feeding the material into the receiving barrel, first set up an annular movable support plate and lay the annular net bag on the annular movable support plate, set a sling on the outer edge of the annular net bag to bypass the barrel mouth of the receiving barrel, so that the other end of the sling is fixed to the outer barrel wall of the receiving barrel by a wire tie. Start the forming machine, add cotton fibers into the receiving barrel through the material dispensing mechanism, and wet the cotton fibers during the falling process, and adjust the receiving barrel on the forming machine to rotate around its center line, so as to achieve the laying of cotton fibers layer by layer in the receiving barrel. After laying the wet cotton fibers, the cotton fibers are alternately stepped on by two tamping blocks to achieve the compaction and molding of the cotton fibers, and the wet cotton fibers are tamped layer by layer. When the cotton fibers are added to the preset amount, the transfer lug is assembled on the lifting screw on the receiving barrel, and the transfer hook on the crane lifting device is started to cooperate with the transfer lug to lift the receiving barrel into the degreasing machine for degreasing treatment. After the degreasing process is completed, the transfer lug is assembled on the lifting screw on the receiving barrel, and the transfer hook on the crane lifting device is started to cooperate with the transfer lug to lift the receiving barrel into the unloader for unloading. During the clamping process of the receiving barrel, the guide mechanism guides the receiving barrel to accurately position it on the unloader frame, and then the barrel clamping mechanism is started to clamp and fix the barrel, and the degreased cotton cake is pushed out of the receiving barrel by the removal mechanism. After the cotton cake is pushed out of the receiving barrel, the wire is loosened, and the buckle hook set at the other end of each tie is hung on the transfer hook of the crane lifting device, and the crane lifting device is started to lift the cotton cake into the dehydrator for dehydration.

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