[0047] Please refer to the attached Figures 1 to 5 , Figure 1 It is the perspective view of the fiber opener of the utility model embodiment, Figure 2 It is the structure schematic view of the first main shaft 2 and the second main shaft 3 of the fiber opener of the utility model embodiment, Figure 3 It is the first view of the first spiral structure 21 of the fiber opener of the utility model embodiment, Figure 4 It is the second view of the first spiral structure 21 of the fiber opener of the utility model embodiment, Figure 5The utility model embodiment provides a cavitation structure 11 schematic view of unscrambler. The utility model embodiment provides an unscrambler, including the casing 1 that is internally provided with the cavity, and rotatably setting first spindle 2 in the cavity, first spindle 2 outside is provided with first screw assembly and is formed with first screw channel by first screw assembly, when the rotation of first spindle 2, material in the cavity moves along first direction through first screw channel, first screw assembly includes first screw structure 21, and first screw channel includes first screw groove 211 formed by first screw structure 21, and first screw groove 211 is single channel groove, the region of casing 1 inside corresponds to first screw groove 211 is provided with cavitation structure 11, and first screw groove 211 is communicated in cavitation structure 11, and the direction of propelling force produced by the rotation of first screw structure 21 is opposite with first direction, wherein, the material in first screw groove 211 is solid-liquid mixture containing fiber material.

[0048] Optionally, the first screw assembly can be a structure extending on the surface of the first spindle 2, for example, the first screw assembly is a spiral structure extending and protruding on the surface of the first spindle 2. Optionally, the first screw assembly can also be a sleeve arranged on the outside of the first spindle 2, and the sleeve is provided with a protruding spiral structure.

[0049] It is understandable that the material entering the cavity will move along the first direction and will eventually be discharged by the discharge machine 5 at the end of the first direction. The first spiral groove 211 is a single-channel groove, which means that when the material in the first spiral groove 211 is subjected to both the pushing force in the first direction applied by the front propulsion spiral structure and / or the feeder 4 and the pushing force in the opposite direction applied by the first spiral structure 21, it can only move along the spiral channel of the first spiral groove 211 in the first direction. During this process, some of the material squeezed by the opposing force will leave the first spiral groove 211 and enter the cavitation structure 11, and then move along the first direction in the cavitation structure 11 or be squeezed back into the first spiral groove 211. Specifically, after the material in the cavity is captured by the first spiral assembly, it moves along the first spiral channel. When the material moves into the first spiral channel formed by the first spiral structure 21, the pushing force generated by the rotation of the first spiral structure 21 acts in the opposite direction to the first direction, causing the material to be squeezed in the first spiral groove 211. At this time, cavitation bubbles are generated under the high temperature and high pressure environment caused by the friction and squeezing between the material and the first spiral structure 21. Under the pushing force generated by the rotation of the first spiral structure 21, the material is gradually squeezed into the cavitation structure 11 on the inner wall of the housing 1. After entering the cavitation structure 11, the squeezing pressure on the material decreases, the cavitation bubbles burst and release huge energy. The energy released when the cavitation bubbles burst will cause the hydrogen bonds between the fibers to break, causing the fiber bundle to disintegrate into single fibers. The fiber material in the material is effectively separated and defiberized. In this embodiment, in addition to mechanical friction, the cavitation reaction is added to the defiberization of the material, so that the fiber material in the material is effectively separated and the fiber separation efficiency is improved. It should be explained that cavitation reaction refers to the process in which cavitation cavities (bubbles) are formed, developed, and collapsed in a liquid due to a decrease in local pressure. When cavitation collapses, extremely high local pressure and temperature are generated, forming shock waves or high-speed microjets, releasing huge amounts of energy. In this embodiment, the material is a solid-liquid mixture containing fibrous materials, which provides the medium for cavitation reaction to occur on the fibrous materials.

[0050] like Figure 6 As shown, Figure 6 This is a cross-sectional view of the fiber unwinding machine according to an embodiment of the present invention. In some embodiments, a feeder 4 is provided at the starting end of the housing 1 in the first direction, and the feeder 4 is used to feed material into the cavity; a discharger 5 is provided at the ending end of the housing 1 in the first direction, and the discharger 5 is used to discharge material from the cavity. In some embodiments, a lifting device 41 and a rotating device 42 are provided for the feeder 4, so that the feeder 4 can be vertically lifted and horizontally rotated during maintenance, which facilitates operation and maintenance. In some embodiments, both the feeder 4 and the discharger 5 adopt a screw conveyor method.

[0051] like Figure 1As shown, in some embodiments, the housing 1 is provided with several liquid inlets 6 and several liquid outlets 7. The liquid inlets 6 are used to introduce liquid into the cavity, and the liquid outlets 7 are used to discharge the liquid from the cavity. Optionally, the liquid inlets 6 are located at the upper part of the housing 1, and the liquid outlets 7 are located at the bottom of the housing 1. Optionally, the liquid can be water, dilute alkaline solution, oxidizing bleaching solution, or other liquids. The user can add the corresponding liquid according to the actual bleaching or softening needs. For example, introducing water or dilute alkaline solution into the cavity is beneficial for softening the material, while introducing hydrogen peroxide into the cavity is beneficial for bleaching the material. In a pulping and defiberizing process using crop straw as raw material, the crop straw (such as wheat straw, corn straw, etc.) is cut into segments of appropriate length, and the cut straw segments are fed into the feeding mechanism 4 of the defiberizing machine. As the straw segments enter the cavity 1 of the desiccant's casing, the user can add a pretreatment solution (such as water or dilute alkali solution) through the inlet 6 to initially soften the straw fibers. Alternatively, a washing solution (such as dilute alkali solution or surfactant solution) can be added through the inlet 6 to react with the straw fibers, allowing the active substances in the washing solution to react with impurities such as pectin and lignin in the straw, causing them to dissolve. After being squeezed, the washing solution is removed through the outlet 7, improving the whiteness of the straw fibers. Furthermore, an oxidizing bleaching solution (such as hydrogen peroxide solution) can be added through the inlet 6 to wet and integrate with the straw fibers, using the oxidizing bleaching solution to deeply oxidize and decolorize the straw fibers, quickly turning them white.

[0052] like Figure 5 As shown, in some embodiments, the cavitation structure 11 includes a cavitation groove 111 disposed on the inner sidewall of the housing 1. The cavitation groove 111 is opened along a first direction, and the material in the first spiral groove 211 is squeezed into the cavitation groove 111 under the driving force generated by the rotation of the first spiral structure 21. It can be understood that the cavitation groove 111 provides a relatively low-pressure environment for the material overflowing from the first spiral groove 211 due to the squeezing pressure. Thus, the material squeezed into the cavitation groove 111 under high pressure in the first spiral groove 211 will collapse due to the local pressure reduction, causing the cavitation bubbles formed inside the liquid or at the liquid-solid interface in the material to collapse, thereby generating extremely high local pressure and temperature, forming shock waves or high-speed microjets, releasing huge energy, causing the hydrogen bonds between fibers to break, and causing the fiber bundle to disintegrate into single fibers. Furthermore, the cavitation process also eliminates the formation of microorganisms (bacteria, fungi, and bacteria), effectively solving the corrosion problem of the entire system. In other embodiments, the cavitation structure 11 may also include a baffle disposed on the inner sidewall of the housing 1, with a cavitation groove 111 disposed on the side of the baffle facing the first main shaft 2. It should be noted that the cavitation groove 111 mentioned above does not necessarily have to be formed on the component; it can also be a gap between two components, as long as it can provide a relatively low-pressure containment environment for the material squeezed out of the first spiral groove 211.

[0053] As Figure 7 and Figure 8 shown, Figure 7 is the first view of the second spiral structure 22 of the fiber opener according to the embodiment of the utility model, Figure 8 is the second view of the second spiral structure 22 of the fiber opener according to the embodiment of the utility model. In some embodiments, the first spiral assembly further comprises a second spiral structure 22, and the first spiral structure 21 is arranged on one side of the second spiral structure 22 facing the first direction; the first spiral channel comprises a second spiral groove 221 formed by the second spiral structure 22; the pushing force generated by the rotation of the second spiral structure 22 acts in a direction opposite to the first direction; the second spiral structure 22 is provided with a first through groove 222, and the first through groove 222 is used for connecting adjacent grooves of the second spiral groove 221 in the first direction. It should be explained that the first spiral structure 21 is arranged on one side of the second spiral structure 22 facing the first direction, that is, the first spiral structure 21 is arranged on one side of the second spiral structure 22 close to the discharging machine 5.

[0054] It can be understood that although the cooperation design of the first spiral structure 21 and the cavitation structure 11 has a large fiber opening capacity, in order to make the material more thoroughly opened in the action of the first spiral structure 21 and the cavitation structure 11, the material should be crushed before entering the first spiral structure 21. Therefore, the second spiral structure 22 is arranged in front of the first spiral structure 21 in this embodiment, so that the material is crushed before entering the first spiral structure 21, thereby improving the fiber opening effect of the material under the action of the first spiral structure 21 and the cavitation structure 11. Specifically, after the material enters the cavity, it will be captured by the second spiral structure 22 before entering the first spiral structure 21 and move along the second spiral channel 311; since the pushing force generated by the rotation of the second spiral structure 22 acts in a direction opposite to the first direction, the material in the second spiral groove 221 will be extruded and rubbed, and preliminary crushing treatment is performed; wherein the first through groove 222 connects adjacent grooves of the second spiral groove 221, and the material in the second spiral groove 221 will move in the first direction along the second spiral groove 221 after being sufficiently extruded and / or pass through the first through groove 222 to enter the next groove of the second spiral groove 221, effectively ensuring the continuous movement of the material. Finally, the material extruded and crushed by the second spiral structure 22 enters the first spiral structure 21 in the first direction.

[0055] As Figure 9 and Figure 10 shown, Figure 9 is the first view of the third spiral structure 23 of the fiber opener according to the embodiment of the utility model, Figure 10The second view of the third spiral structure 23 of the fiber opening machine is illustrated in the embodiments of the present application. In some embodiments, the first spiral assembly further comprises a third spiral structure 23, and the first spiral structure 21 is arranged on one side of the third spiral structure 23 facing the first direction; the first spiral channel comprises a third spiral groove 231 formed by the third spiral structure 23; and the pushing force generated by the rotation of the third spiral structure 23 has the same direction as the first direction. It should be explained that the first spiral structure 21 is arranged on one side of the third spiral structure 23 facing the first direction, that is, the first spiral structure 21 is arranged on one side of the third spiral structure 23 close to the discharging machine 5.

[0056] It can be understood that the material needs a pushing force to move in the cavity along the first direction, and the rotation of the third spiral structure 23 can provide the pushing force for the material to move along the first direction. Specifically, after the material enters the cavity, it will first enter the third spiral structure 23 and move along the third spiral channel; since the pushing force generated by the rotation of the third spiral structure 23 has the same direction as the first direction, the material will move along the third spiral groove 231 in the first direction under the action of the third spiral structure 23. Finally, the material pushed by the third spiral structure 23 enters the second spiral structure 22 or the first spiral structure 21 along the first direction.

[0057] In some embodiments, the second spiral structure 22 and the third spiral structure 23 are arranged alternately in front of the first spiral structure 21. It can be understood that the second spiral structure 22 and the third spiral structure 23 are arranged alternately in front of the first spiral structure 21, which can make the material be pushed, extruded and broken multiple times before entering the first spiral structure 21, so that the material is broken more thoroughly. It should be explained that the second spiral structure 22 or the third spiral structure 23 can be connected with the first spiral structure 21, but the starting section of the first main shaft 2 should be the third spiral structure 23 having the pushing force in the first direction, and the material entering the cavity through the feeding machine 4 should first contact the third spiral structure 23 and move in the first direction under the action of the third spiral structure 23.

[0058] In some embodiments, the first spiral assembly further comprises a fourth spiral structure 24, and the fourth spiral structure 24 is arranged on one side of the first spiral structure 21 facing the first direction; the first spiral channel comprises a fourth spiral groove 241 formed by the fourth spiral structure 24; the pushing force generated by the rotation of the fourth spiral structure 24 has the opposite direction to the first direction; and the fourth spiral structure 24 is provided with a second through groove 242 for connecting adjacent grooves of the fourth spiral groove 241 in the first direction. It should be explained that the fourth spiral structure 24 is arranged on one side of the first spiral structure 21 facing the first direction, that is, the fourth spiral structure 24 is arranged on one side of the first spiral structure 21 close to the discharging machine 5.

[0059] It can be understood that, in order to make the material more thoroughly be frayed after the action of the first spiral structure 21 and the cavitation structure 11, the material should be processed after passing through the first spiral structure 21 to make the material be further compressed and rubbed to be separated. Therefore, the embodiment sets the fourth spiral structure 24 after the first spiral structure 21 to make the material be further frayed after passing through the first spiral structure 21, thereby improving the quality of the final output of the material. It needs to be explained that the fraying refers to the phenomenon that the fiber cell wall is raised, torn, separated and the like in the pulp and paper production by physical or chemical beating, which makes the two ends of the fiber be separated and become like a broom, thereby increasing the surface area of the fiber and the interweaving and combining ability between the fibers, and enhancing the strength and quality of the paper. Specifically, the material will enter the fourth spiral structure 24 after passing through the first spiral structure 21 and move along the fourth spiral channel, and the fiber cell wall is raised, torn, separated and the like by the compression and rubbing action of the fourth spiral structure 24, thereby increasing the surface area of the fiber and the interweaving and combining ability between the fibers; wherein the second through groove 242 connects adjacent grooves of the fourth spiral groove 241, and the material in the fourth spiral groove 241 will move in the first direction after being sufficiently extruded and / or enter the next groove of the fourth spiral groove 241 through the second through groove 242, effectively ensuring the continuous movement of the material.

[0060] In some embodiments, the first spiral assembly further comprises a fifth spiral structure 25, and the fifth spiral structure 25 is arranged on one side of the first spiral structure 21 facing the first direction; the first spiral channel comprises a fifth spiral groove 251 formed by the fifth spiral structure 25; and the pushing force generated by the rotation of the fifth spiral structure 25 has the same direction as the first direction. It needs to be explained that the fifth spiral structure 25 is arranged on one side of the first spiral structure 21 facing the first direction, that is, the fifth spiral structure 25 is arranged on the side of the first spiral structure 21 close to the discharging machine 5.

[0061] It can be understood that the material needs a pushing force to move in the first direction in the cavity, and the rotation of the fifth spiral structure 25 can provide the pushing force for the material to move in the first direction. Specifically, the material will move along the fifth spiral channel after entering the fifth spiral structure 25, and since the pushing force generated by the rotation of the fifth spiral structure 25 has the same direction as the first direction, the material will move in the first direction along the fifth spiral groove 251 under the action of the fifth spiral structure 25. Finally, the material pushed by the fifth spiral structure 25 enters the fourth spiral structure 24 in the first direction or is discharged through the discharging machine 5.

[0062] As shown in Figure 1 and Figure 11 , the fifth spiral structure 25 is arranged on one side of the first spiral structure 21 facing the first direction, that is, the fifth spiral structure 25 is arranged on the side of the first spiral structure 21 close to the discharging machine 5. Figure 11This is a schematic diagram of the friction structure 12 of the fiber unwinding machine according to an embodiment of the present invention. In some embodiments, the fourth helical structure 24 and the fifth helical structure 25 are alternately arranged, and the friction structure 12 is provided on the inner side of the housing 1 corresponding to the area of ​​the fourth helical structure 24 and / or the fifth helical structure 25. The friction structure 12 is used to rub against the material extruded from the fourth helical groove 241 and / or the fifth helical groove 251. It can be understood that the friction structure 12 is provided to make the material passing through the fourth helical structure 24 and the fifth helical structure 25 more thoroughly fuzzed, so that the material overflowing from the fourth helical groove 241 and the fifth helical groove 251 can have sufficient friction with the friction structure 12, so that the material is fully kneaded, causing the fiber cell walls to produce phenomena such as fuzzing, tearing, and splitting, increasing the surface area of ​​the fibers, and improving the interweaving and bonding ability between fibers. In some embodiments, the friction structure 12 may include multiple straight grooves or straight protrusions arranged along the first direction, which can effectively increase the friction area, so that the material is subjected to stronger friction when passing through, and enhance the kneading effect on the material. In some embodiments, the friction structure 12 may also include a plurality of evenly distributed spherical grooves or a plurality of spherical protrusions, which can increase the uniformity of friction, so that the material is subjected to a more uniform kneading action when passing through, and further improve the filament-making effect.

[0063] It is understandable that the driving force direction of the fourth spiral structure 24 is opposite to that of the first spiral structure, while the driving force direction of the fifth spiral structure 25 is the same as that of the first spiral structure. This alternating arrangement ensures that the material experiences driving forces in different directions during the fiber unwinding process, further improving the unwinding effect. It allows the material to undergo stronger compression and kneading during unwinding, thereby improving the final output quality. The friction structure 12 is designed to further thoroughly fuzz and spin the material through the fourth spiral structure 24 and the fifth spiral structure 25, allowing the material overflowing from the fourth spiral groove 241 and the fifth spiral groove 251 to fully rub against the friction structure 12. This results in the material undergoing sufficient kneading, causing the fiber cell walls to fray, tear, and separate, increasing the fiber surface area and improving the interweaving and bonding ability between fibers.

[0064] In a feasible implementation, after the material enters the cavity of the casing 1 of the defiber machine, it will first be captured by the third spiral structure 23. Under the pushing force applied by the third spiral structure 23, it will move along the third spiral groove 231 in the first direction. The material passing through the third spiral structure 23 will enter the second spiral structure 22 or the first spiral structure 21 in the first direction. The material entering the second spiral structure 22 will enter the third spiral structure 23 or the first spiral structure 21 in the first direction. The material entering the second spiral structure 22 will be crushed by pressure, and the material entering the first spiral structure 21 will be cavitated. The material is fully de-fibered by the action of the first spiral structure 21; the material entering the first spiral structure 24 or the fifth spiral structure 25 will enter the fourth spiral structure 24 or be discharged through the discharge machine 5 along the first direction; the material entering the fourth spiral structure 24 will enter the fifth spiral structure 25 or be discharged through the discharge machine 5 along the first direction; the material entering the fourth spiral structure 24 will be further squeezed, kneaded and de-fiberized by pressure; the material entering the fifth spiral structure 25 will move along the fifth spiral groove 251 in the first direction under the action of the driving force.

[0065] like Figure 3 and Figure 7 As shown, in some embodiments, the first spiral structure 21 is provided with a first rough surface 212, which is used to rub against the material in the first spiral groove 211; and / or, the second spiral structure 22 is provided with a second rough surface 223, which is used to rub against the material in the second spiral groove 221; and / or, the third spiral structure 23 is provided with a third rough surface, which is used to rub against the material in the third spiral groove 231; and / or, the fourth spiral structure 24 is provided with a fourth rough surface, which is used to rub against the material in the fourth spiral groove 241; and / or, the fifth spiral structure 25 is provided with a fifth rough surface, which is used to rub against the material in the fifth spiral groove 251. It is understood that the arrangement of the first rough surface 212, the second rough surface 223, the third rough surface, the fourth rough surface, and the fifth rough surface allows the material traveling in the first spiral channel to be fully kneaded, promoting the separation and filamentation of the material. Optionally, the first roughened surface 212 can be a twill pattern provided on the side of the first helical structure 21 facing the first helical groove 211. Optionally, the second roughened surface 223 can be a twill pattern provided on the side of the second helical structure 22 facing the second helical groove 221. Optionally, the third roughened surface can be a twill pattern provided on the side of the third helical structure 23 facing the third helical groove 231. Optionally, the fourth roughened surface can be a twill pattern provided on the side of the fourth helical structure 24 facing the fourth helical groove 241. Optionally, the fourth roughened surface can be a twill pattern provided on the side of the fourth helical structure 24 facing the first helical groove 211. Optionally, the fifth roughened surface can be a twill pattern provided on the side of the fifth helical structure 25 facing the fifth helical groove 251.

[0066] It should be noted that the first spiral structure 21, the second spiral structure 22, the third spiral structure 23, the fourth spiral structure 24, and the fifth spiral structure 25 are all located on the first main shaft 2. Therefore, during the design phase, the pitch of the first spiral structure 21, the second spiral structure 22, the third spiral structure 23, the fourth spiral structure 24, and the fifth spiral structure 25 can be adjusted to control the material propulsion force of the first spiral groove 211, the second spiral groove 221, the third spiral groove 231, the fourth spiral groove 241, and the fifth spiral groove 251. It can be understood that a smaller spiral pitch indicates a stronger pushing effect on the material at the same rotational speed.

[0067] like Figure 1 , Figure 2 and Figure 6 As shown, in some embodiments, the fiber unwinding machine further includes a second main shaft 3 rotatably disposed in the cavity. The second main shaft 3 is arranged parallel to the first main shaft 2. A second helical assembly 31 and a second helical channel 311 formed by the second helical assembly 31 are disposed on the outer side of the second main shaft 3. The first helical assembly extends into the second helical channel 311, and the second helical assembly 31 extends into the first helical channel. It should be explained that, in order to avoid interference between the rotation of the first main shaft 2 and the second main shaft 3, the first helical assembly should be disposed corresponding to the second helical groove 221. Therefore, the multi-segment helical structure disposed on the second main shaft 3 should correspond to the multi-segment helical structure disposed on the first main shaft 2, and the propulsive force generated when the second helical assembly 31 rotates should be in the same direction as the propulsive force generated when the first helical assembly rotates. It is understandable that, since the second spiral component 31 extends into the first spiral channel and the first spiral component extends into the second spiral channel 311, the material can move interactively between the first spiral channel and the second spiral channel 311, increasing the material processing path and time, making the material processing more uniform. Through the design of the dual main shaft and multi-spiral structure, the material will be subjected to multiple compressions and frictions in the fiber debonding machine, improving the fiber separation efficiency.
