Description

Technical Field

[0001] The present application relates to the field of yarn storage, and in particular to a cotton yarn storage device. Background Art

[0002] Currently, yarn storage mainly involves winding the yarn into a roller, so that the yarn is wound on a roller body for storage, so that the yarn can be directly unwound when it is used next time, which is also convenient for use.

[0003] In the related technology, a Chinese patent with application number CN202221995281.5 proposes to adjust the tension applied to the yarn when it is rolled up according to the different materials of the yarn, so as to maintain an appropriate tension during the yarn rolling process and avoid the yarn being damaged by a large tensile force.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: When the yarn quality is poor, the actual upper limit of the tension that the yarn can withstand will be lower than the theoretical yarn tension index. When encountering such yarn, it is difficult to adjust the tension, and when the professional ability of the staff is insufficient or the operation is wrong, it is very easy to cause the yarn to lose elasticity and be directly damaged. Summary of the invention

[0005] In order to improve the problem that the yarn can easily lose its elasticity and be directly damaged due to insufficient professional ability or operational errors of the staff, the present application provides a cotton yarn storage device.

[0006] The present application provides a cotton yarn storage device that adopts the following technical solution: A cotton yarn storage device comprises: a storage roller, forming a roller body for winding and collecting cotton yarn and a baffle plate to prevent the cotton yarn from deviating from the roller body; an elastic bag, forming an inner chamber for accommodating the roller body and the cotton yarn and a connection port connected to the inner chamber for the roller body to release and reel in the yarn; a connector, used to connect the side of the elastic bag facing away from the inner chamber to the baffle plate, and the connector and the elastic bag form an outer chamber and an external interface connected to the outer chamber on the side facing away from the inner chamber; wherein the roller body is rotatably connected to the baffle plate; the external interface is used to connect an external pneumatic structure to switch the outer chamber between an air injection state and an air extraction state; when the outer chamber is in the air injection state, the elastic bag can at least be pressed against the cotton yarn; when the outer chamber is in the air extraction state, the elastic bag can at least be separated from the cotton yarn.

[0007] By adopting the above technical solution, the storage roller is used to be placed on the machining equipment to reel in the manufactured cotton yarn. During the reeling process, the elastic bag is used to press against the cotton yarn, so that the cotton yarn can be compacted on the roller body. When the tension on the cotton yarn is too large, it is easy to cause fatigue or damage to the elasticity of the cotton yarn, which is easy to affect the quality of the cotton yarn itself. Therefore, when the cotton yarn is reeled in, the tensile force of the cotton yarn wound on the roller body will be within a suitable range. In order to ensure the quality of the cotton yarn, it is easy for the cotton yarn to be difficult to be tightly wound on the roller body. Therefore, the present application uses the method of compacting the cotton yarn with an elastic bag so that the cotton yarn is tightly wound on the roller body, thereby better increasing the amount of cotton yarn stored in a limited space, and also improving the stability of storage. After the storage is completed, that is, after the cotton yarn is completely wound on the roller body, the elastic bag is used to tighten the cotton yarn to wrap the cotton yarn and prevent the cotton yarn from being exposed to the outside. The cotton yarn is wrapped and stored to better prevent dust from adhering and improve the quality assurance of the cotton yarn itself when the cotton yarn is stored.

[0008] Optionally, the connector is an elastic structure; the elastic modulus of the connector is greater than the elastic modulus of the elastic bag.

[0009] By adopting the above technical solution, the elastic modulus of the connector is greater than the elastic modulus of the elastic bag. Then, after the air enters the outer chamber, when the pressure in the outer chamber is too high, the connector can be deformed to prevent the elastic bag from applying excessive pressure to the cotton yarn and causing damage. At the same time, it is also possible to wrap more cotton yarn in the inner chamber, and then the connector expands to accommodate more cotton yarn. At the same time, after the connector is deformed, there will be elastic force, so that the connector can directly wrap the cotton yarn tightly to prevent the cotton yarn from falling off, etc., and better ensure the storage effect.

[0010] Optionally, an air inlet is also provided on the elastic bag; the air inlet is used to be externally connected to the pneumatic structure; the pneumatic structure is used to add warm gas into the inner chamber; the air inlet, the inner chamber and the connecting port are connected in sequence.

[0011] By adopting the above-mentioned technical scheme, by adding warm gas into the inner chamber, the warm gas can be used to heat the cotton yarn. After the cotton yarn is produced, it needs to be transported in the external air before entering the inner chamber, and the cotton yarn has a strong adsorption force, so the cotton yarn is easy to adsorb dust and moisture. Therefore, the use of warm air can not only blow away the dust, but also evaporate the moisture on the cotton yarn. Therefore, the cotton yarn can be stored in a dust-free and moisture-free state, thereby avoiding moisture affecting the life of the cotton yarn, which is conducive to ensuring the quality of the cotton yarn itself for a long time.

[0012] Optionally, a plurality of pressure rollers are arranged on the inner wall surface of the inner chamber; the plurality of pressure rollers are parallel to the axis of the roller body; wherein, when the outer chamber is in the air injection state, the plurality of pressure rollers are directly or indirectly in contact with the cotton yarn on the roller body.

[0013] By adopting the above technical solution, multiple pressing rollers are arranged to press the cotton yarn on the roller body so that the cotton yarn is tightly wound on the roller body. The pressing roller is used to avoid most of the elastic bags from contacting the yarn, which causes the cotton yarn to be easily damaged by friction, so the use of the pressing roller ensures the quality of the cotton yarn itself to a certain extent.

[0014] Optionally, two baffles are provided, which are respectively provided at two ends of the roller body; connecting parts are provided on the two baffles, and the connecting body is located between the two connecting parts and is detachably connected to the two connecting parts.

[0015] By adopting the above technical solution, the connector and the connecting part are detachably connected, so the connector can be removed relative to the baffle to fully expose the roller body and the cotton yarn on the roller body, which is convenient for adjusting the cotton yarn.

[0016] Optionally, a protrusion protruding outward is formed on the elastic bag, and the protrusion is used to form the connecting port and a connecting cavity connecting the connecting port with the inner chamber; a first connecting buckle is provided on the protrusion, and a second connecting buckle is provided on the connector; when the cotton yarn is wrapped around the inner chamber, the protrusion fits with the connector, and the first connecting buckle is connected and fixed to the second connecting buckle.

[0017] By adopting the above-mentioned technical solution, the protrusion is mainly provided to make the protrusion fit with the connector so that the connecting port can be better closed, and after the protrusion is fixed to the connector, the relative elastic bag will also be fixed to the connector or the contact between the elastic bag and the connector will be more stable, thereby achieving the goal of completely wrapping the cotton yarn to protect the cotton yarn for easy retrieval and transportation.

[0018] Optionally, the elastic bag further includes a wrapping portion, which is used to form the inner chamber; and the wrapping portion is detachably connected to the protruding portion.

[0019] By adopting the above-mentioned technical solution, the wrapping part and the protruding part are detachably connected. The protruding part can be removed in some cases, and then the inner chamber formed by the wrapping part is exposed, which is convenient for cleaning the inner chamber and the connecting cavity. Therefore, after a period of use, dust on the cotton yarn or waste scraps of the cotton yarn are easily adhered to the inner chamber and the connecting cavity. After the protruding part is removed, it is convenient to clean and the cleaning effect will also be improved.

[0020] Optionally, a sealing cloth is provided outside the connection port; the first connection buckle is connected to the sealing cloth; when the first connection buckle is connected and fixed with the second connection buckle, the sealing cloth is completely fitted with the connector to seal the connection port.

[0021] By adopting the above technical solution, when the protrusion is attached to the connector, the connection port on the protrusion is exposed to the outside, so the sealing cloth is attached to the connector again, and the sealing cloth covers the connection port to seal the connection port, thereby better ensuring that the cotton yarn in the inner chamber is in a sealed environment and improving the protection of the cotton yarn. The sealing cloth is also attached to the connector, which can increase the stability of the fixing of the protrusion and the connector.

[0022] Optionally, the air inlet is opened on the protruding portion, and when the protruding portion is in contact with the connecting body, the sealing cloth is in contact with the connecting body, and the air inlet is in contact with the connecting body, so that the air inlet is sealed.

[0023] Optionally, the length of the pressure roller is smaller than the length of the roller body; multiple pressure rollers are arranged along the length direction of the roller body and along the circumference of the axis of the pressure roller; multiple pressure rollers are staggered to form multiple ventilation cavities in the inner chamber that are connected to the connecting port.

[0024] By adopting the above technical solution, it is avoided that when the pressure roller and the cotton yarn are pressed tightly, the air cannot bypass the pressure roller, thereby causing poor air circulation in the inner chamber. The length of the pressure roller is less than the length of the roller body, and multiple pressure rollers are arranged in both directions, so that the air can sweep along the end faces of multiple pressure rollers in the inner chamber, and the dust and waste adhered to the pressure roller can be better blown away and cleaned, which improves the effect of cleaning dust and waste, and also increases the contact area between the cotton yarn and the warm air, so as to better keep the cotton yarn dry.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The elastic bag wraps the roller body, and when the outer cavity formed by elasticity is injected with air, the elastic bag will press against the yarn on the roller body, so that the yarn is wound on the roller body. The elastic bag presses the yarn on the roller body and compacts the yarn to prevent the yarn from being broken or the yarn from being wound loosely. 2. An air inlet is also formed on the elastic bag, and warm air enters the inner chamber through the air inlet and fully contacts with the yarn. The warm air can not only blow away the dust, but also evaporate the moisture on the cotton yarn. Therefore, the cotton yarn can be stored in a dust-free and moisture-free state, thereby avoiding moisture affecting the life of the cotton yarn. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is combined with Figure 1-13This application is described in further detail.

[0029] The embodiment of the present application discloses a cotton yarn storage device.

[0030] A cotton yarn storage device comprises a storage roller 1, an elastic bag 2 and a connector 3.

[0031] The storage roller 1 forms a roller body 11 for winding and collecting cotton yarn and a baffle 12 for preventing the cotton yarn from deviating from the roller body 11, and the baffle 12 is a circular plate. The elastic bag 2 forms an inner chamber 21 for accommodating the roller body 11 and the cotton yarn, and a connection port 22 connected to the inner chamber 21 for the roller body 11 to release and reel in the yarn. The connector 3 is used to connect the side of the elastic bag 2 facing away from the inner chamber 21 to the baffle 12, and the connector 3 and the elastic bag 2 form an outer chamber 23 on the side facing away from the inner chamber 21 and an external interface 24 connected to the outer chamber 23.

[0032] In this embodiment, the connector 3 is an annular cylinder, and the connector 3 is embedded in the storage roller 1 on one side of the storage roller 1 and abuts against the baffle 12 of the storage roller 1. The elastic bag 2 is directly fixed to the inner wall surface of the connector 3, wherein the outer contour of the elastic bag 2 is fixed to the inner wall surface of the connector 3, and then the elastic bag 2 forms an outer chamber 23 with the inner wall surface of the connector 3. After the connector 3 is embedded in the storage roller 1, the elastic bag 2 is located between the inner wall surface of the connector 3 and the cotton yarn.

[0033] Preferably, in this embodiment, the take-up roller 1 is used to be installed on a wire-taking device. The take-up roller 1 is installed on the wire-taking device, and the cotton yarn is wound around the roller body 11. The wire-taking device rotates the take-up roller 1, thereby winding the cotton yarn around the roller body 11. A groove is provided on the take-up roller 1, and the groove is used to install the take-up roller 1 on the output shaft of the wire-taking device. The baffle 12 is located on one side of the groove opening, and the other side of the baffle 12 is used for the connector 3 to be embedded. The end of the connector 3 away from the baffle 12 is blocked, so that after the connector 3 abuts against the baffle 12, the inner chamber 21 formed by the elastic band is closed. The wire-taking device adopts the existing technology, and the wire-taking device can directly adopt a servo motor. The take-up roller 1 can be installed on the servo motor to realize the rotation and take-up of the take-up roller 1. After the connector 3 is embedded in the roller body 11, the connector 3 is fixed to the baffle 12. Since the cotton yarn passes through the connection port 22 and enters the inner chamber 21, when the roller body 11 rotates, the cotton yarn will limit the rotation of the connector 3 and the elastic bag 2. The roller body 11 is rotationally connected to the baffle 12, so the roller body 11 is wound up, while the elastic bag 2 is stationary and does not rotate. In addition, during installation, the baffle 12 is connected to some fixed frames, such as the roller body 11 is connected to the servo motor, and the baffle 12 is connected to the frame on which the servo motor is installed, so the baffle 12 is fixed and the roller body 11 rotates.

[0034] The external interface 24 is used to connect the pneumatic structure 4 to the outside, so that the outer chamber 23 can switch between the gas injection state and the gas extraction state. When the outer chamber 23 is in the gas injection state, the elastic bag 2 can at least be pressed against the cotton yarn; when the outer chamber 23 is in the gas extraction state, the elastic bag 2 can at least be separated from the cotton yarn. The elastic band is pressed against the cotton yarn because the gas in the outer chamber 23 increases and the pressure increases, causing the elastic bag 2 to move away from the connector 3, so the elastic bag 2 is in contact with the cotton yarn. In the process of winding, the elastic bag 2 is pressed against the cotton yarn, so that the cotton yarn can be compacted on the roller body 11. When the tension on the cotton yarn is too large, it is easy to cause fatigue or damage to the elasticity of the cotton yarn, which is easy to affect the quality of the cotton yarn itself. Therefore, when the cotton yarn is wound, the tensile force of the cotton yarn wound on the roller body 11 will be within a suitable range. In order to ensure the quality of the cotton yarn, it is easy for the cotton yarn to be difficult to be tightly wound on the roller body 11. Therefore, the present application utilizes the elastic bag 2 to compress the cotton yarn so that the cotton yarn is tightly wound around the roller body 11, thereby better increasing the amount of cotton yarn stored in a limited space and also improving the stability of storage. After the cotton yarn is completely wound around the roller body 11, the elastic bag 2 is used to press against the cotton yarn, thereby wrapping the cotton yarn and preventing the cotton yarn from being exposed to the outside, thereby wrapping and storing the cotton yarn, better preventing dust from adhering, and improving the quality assurance of the cotton yarn itself when the cotton yarn is stored. The elastic bag 2 is separated from the cotton yarn because the gas in the outer chamber 23 is reduced, and the elastic bag 2 is close to the connector 3, so the elastic bag 2 is away from the cotton yarn.

[0035] Preferably, the elastic bag 2 is made of a rubber film, the edge of which is fixed to the inner wall of the connector 3, and the inner wall of the connector 3 is a curved surface connected end to end, so the rubber film is connected end to end to form the elastic bag 2.

[0036] Preferably, a slot is formed on the baffle 12 for inserting the connector 3 , and the slot and the connector 3 are attracted together by magnetism, so that the connector 3 is fixed to the baffle 12 and the connector 3 is easy to be disassembled from the baffle 12 .

[0037] Specifically, the elastic bag 2 is also provided with an air inlet 25. The air inlet 25 is used to connect to the pneumatic structure 4, wherein an air inlet pipe 41 is provided at the air inlet 25, and the air inlet pipe 41 passes through the outer chamber 23 and extends to the outside of the outer chamber 23, that is, extends to the outside of the connector 3, and forms an interface on the connector 3, and the pneumatic structure 4 is connected to the air inlet 25 through the air inlet pipe 41. The pneumatic structure 4 is used to add warm gas into the inner chamber 21, and the method for the pneumatic structure 4 to add warm gas into the inner chamber 21 is to set an electric heating pipe at the interface of the pneumatic structure 4, and heat the air passing through the electric heating pipe, so that the air entering the inner chamber 21 is warm gas. The air inlet 25, the inner chamber 21 and the connecting port 22 are connected in sequence, and the external air passes through the electric heating pipe, the pneumatic structure 4, the air inlet pipe 41 and the air inlet 25 in sequence to enter the inner chamber 21 and contact the cotton yarn in the inner chamber 21. Then the warm air in the inner chamber 21 is discharged outward at the connection port 22. By adding warm air into the inner chamber 21, the warm air can be used to heat the cotton yarn. After the cotton yarn is produced, it needs to be transported in the external air before entering the inner chamber 21. The cotton yarn has a strong adsorption force, so it is easy to adsorb dust and moisture on the cotton yarn. Therefore, the use of warm air can not only play the role of blowing away dust, but also play the role of evaporating moisture on the cotton yarn. Therefore, the cotton yarn can be stored in a state without dust and moisture, thereby avoiding moisture affecting the life of the cotton yarn, which is conducive to ensuring the quality of the cotton yarn itself for a long time.

[0038] Specifically, a plurality of pressure rollers 5 are arranged on the inner wall surface of the inner chamber 21. The plurality of pressure rollers 5 are parallel to the axis of the roller body 11. When the outer chamber 23 is in the gas injection state, the plurality of pressure rollers 5 are directly or indirectly in contact with the cotton yarn on the roller body 11. The plurality of pressure rollers 5 are arranged to press the cotton yarn on the roller body 11 so that the cotton yarn is tightly wound around the roller body 11. The pressure rollers 5 are used to prevent most of the elastic bags 2 from contacting the yarn, which causes the cotton yarn to be easily damaged by greater friction, so that the use of the pressure rollers 5 guarantees the quality of the cotton yarn itself to a certain extent.

[0039] A specific example of the pressure roller 5 is that the pressure roller 5 is in direct contact with the cotton yarn, the pressure roller 5 is directly fixed on the inner wall of the inner chamber 21, and then the pressure roller 5 protrudes outward relative to the inner wall of the inner chamber 21. Therefore, when the outer chamber 23 is in the air injection state, the pressure roller 5 is in contact with the cotton yarn, that is, the pressure roller 5 is pressed on the cotton yarn. Among them, the pressure roller 5 is directly fixed to the inner wall of the inner chamber 21, or the pressure roller 5 is rotated in cooperation with the inner wall of the inner chamber 21. Therefore, the pressure roller 5 is mainly used to press the cotton yarn. The pressure roller 5 is a rod body, and a smooth coating is set on the surface of the pressure roller 5, so that the cotton yarn can be better wound. If the inner wall of the elastic bag 2 is directly in contact with the cotton yarn, the inner wall of the elastic bag 2 is easy to wear, and leakage and damage are easy to occur after a long time of use. Example 2

[0040] The difference between Example 2 and Example 1 is that: The connector 3 is an elastic structure or a flexible structure. Preferably, the connector 3 is made of a thick rubber film. The elastic modulus of the connector 3 is greater than the elastic modulus of the elastic bag 2. The elastic modulus of the connector 3 is greater than the elastic modulus of the elastic bag 2. Then, after the air enters the outer chamber 23, when the pressure of the outer chamber 23 is too high, the connector 3 can be deformed to prevent the elastic bag 2 from applying excessive pressure to the cotton yarn and causing damage. At the same time, it is also possible to wrap more cotton yarn in the inner chamber 21, and then the connector 3 expands to accommodate more cotton yarn. At the same time, there will be elastic force after the connector 3 is deformed, so that the connector 3 directly wraps the cotton yarn to prevent the cotton yarn from falling off, etc., and better ensure the storage effect.

[0041] Specifically, two baffles 12 are provided, which are respectively provided at both ends of the roller body 11. Connecting parts 13 are provided on the two baffles 12, and the connecting body 3 is located between the two connecting parts 13 and is detachably connected to the two connecting parts 13. The connecting body 3 is detachably connected to the connecting parts 13, so that the connecting body 3 can be removed relative to the baffle 12, so that the roller body 11 and the cotton yarn on the roller body 11 are completely exposed, which is convenient for adjusting the cotton yarn.

[0042] Wherein, the connecting part 13 adopts a zipper, and the detachable connection between the connecting body 3 and the connecting part 13 is detachable and connected in the manner of a zipper. In addition, the connecting part 13 can also adopt a Velcro, and the detachable connection between the connecting body 3 and the connecting part 13 is detachable and connected in the manner of a Velcro. Example 3

[0043] The difference between Example 3 and Example 1 is that: a protruding portion 26 protruding outward is formed on the elastic bag 2, and the protruding portion 26 is used to form the connecting port 22 and the connecting cavity connecting the connecting port 22 with the inner chamber 21. A first connecting buckle is arranged on the protruding portion 26, and a second connecting buckle is arranged on the connecting body 3. When the cotton yarn is wrapped around the inner chamber 21, the protruding portion 26 fits with the connecting body 3, and the first connecting buckle is connected and fixed with the second connecting buckle. The protruding portion 26 is mainly provided to make the protruding portion 26 fit with the connecting body 3 so that the connecting port 22 can be better closed, and after the protruding portion 26 is fixed to the connecting body 3, the relative elastic bag 2 will also be fixed to the connecting body 3 or the contact between the elastic bag 2 and the connecting body 3 will be more stable, so as to completely wrap up the cotton yarn to protect the cotton yarn for easy access and transportation.

[0044] The first connecting buckle and the second connecting buckle are Velcro. A slit 31 is provided on the connector 3, and the elastic bag 2 extends outward at the position of the slit 31, and the elastic bag 2 is tightly fixed to the inner wall surface of the slit 31, so the part of the elastic bag 2 extending outward from the slit 31 is a protrusion 26. The elastic bag 2 also includes a wrapping portion 27, and the wrapping portion 27 is used to form the inner chamber 21. The wrapping portion 27 is the elastic bag 2 located inside the connector 3.

[0045] In some embodiments, the wrapping portion 27 is detachably connected to the protruding portion 26. The pneumatic structure 4 supplies air to the wrapping portion 27 and the protruding portion 26 at the same time, so that the wrapping portion 27 and the protruding portion 26 expand. The wrapping portion 27 is located inside the connector 3, and the edge contour of the wrapping portion 27 is fixed to the inner wall surface of the connector 3. The protruding portion 26 is fixed to the outside of the connector 3, and the connecting cavity formed by the protruding portion 26 is connected to the crack 31. Among them, a first docking ring is provided on the protruding portion 26, and a second docking ring is provided on the connector 3. The first docking ring and the second docking ring are docked together to fix the protruding portion 26 to the connector 3. The first docking ring and the second docking ring are both magnets, so the first docking ring and the second docking ring are magnetically detachable, that is, the protruding portion 26 and the wrapping portion 27 are detachably connected. The wrapping portion 27 is detachably connected to the protruding portion 26. In some cases, the protruding portion 26 can be removed, and then the inner chamber 21 formed by the wrapping portion 27 is exposed, which is convenient for cleaning the inner chamber 21 and the connecting cavity. Therefore, after a period of use, dust on the cotton yarn or waste scraps of the cotton yarn are easily adhered to the inner chamber 21 and the connecting cavity. After the protruding portion 26 is removed, cleaning is convenient and the cleaning effect will also be improved.

[0046] Specifically, a sealing cloth 6 is provided outside the connection port 22; the first connection buckle is connected to the sealing cloth 6; when the first connection buckle is connected and fixed to the second connection buckle, the sealing cloth 6 is completely fitted with the connector 3 to seal the connection port 22. The air inlet 25 is provided on the protrusion 26; when the protrusion 26 is fitted with the connector 3, the sealing cloth 6 is fitted with the connector 3, and the air inlet 25 is in contact with the connector 3 to seal the air inlet 25. When the protrusion 26 is fitted with the connector 3, the connection port 22 on the protrusion 26 is exposed to the outside, so the sealing cloth 6 is fitted with the connector 3 again, and the sealing cloth 6 covers the connection port 22 to seal the connection port 22, thereby better ensuring that the cotton yarn in the inner chamber 21 is in a sealed environment and improving the protection of the cotton yarn. The sealing cloth 6 is also fitted with the connector 3, which can increase the stability effect of fixing the protrusion 26 with the connector 3.

[0047] The sealing cloth 6 is arranged at the lower end of the connection port, so that the sealing cloth 6 hangs down and does not contact the yarn. In another solution, the sealing cloth 6 is arranged at the upper end of the connection port, the sealing cloth hangs down and contacts the yarn, a fleece layer is arranged on the sealing cloth 6, the fleece layer is a Velcro with a fleece surface, and the sealing cloth 6 contacts the yarn to clean the hair scraps on the yarn. Example 4

[0048] The difference between Example 4 and Example 1 is that: the length of the pressure roller 5 is less than the length of the roller body 11; multiple pressure rollers 5 are arranged along the length direction of the roller body 11 and along the axis circumference of the pressure roller 5; multiple pressure rollers 5 are arranged in a staggered manner so that multiple ventilation channels 51 connected to the connecting port 22 are formed in the inner chamber 21. This avoids the situation where the air cannot bypass the pressure roller 5 when the pressure roller 5 is pressed against the cotton yarn, resulting in poor air circulation in the inner chamber 21. The length of the pressure roller 5 is less than the length of the roller body 11, and multiple pressure rollers 5 are arranged in both directions, so that the air can sweep the air along the end faces of multiple pressure rollers 5 in the inner chamber 21, better blow away the dust and debris adhered to the pressure roller 5, improve the effect of cleaning dust and debris, and also increase the contact area between the cotton yarn and the warm air, so as to better keep the cotton yarn dry.

[0049] Specifically, the pressing roller 5 includes a pressing portion 52 and a shaft portion, wherein the shaft portion is fixed to the inner wall surface of the inner chamber 21, and the pressing portion 52 is fixed to the shaft portion. The end surface of the pressing portion 52 is an arc-shaped guide surface. The arc-shaped guide surface is to allow air to pass through better, and in some cases, there is an elastic bag 2 that presses the cotton yarn between the two pressing portions 52, and the guide arc surface can allow the cotton yarn to be offset to the pressing portion 52, avoiding the situation where the position of some cotton yarns cannot be guaranteed.

[0050] In other embodiments, the difference from Embodiment 1 is that after the cotton yarn is wound on the roller body 11, the diameter of the cotton yarn roller formed by the cotton yarn being wound on the roller body 11 is greater than the diameter of the baffle 12. The connector 3 includes a first connecting film 32 and a second connecting film 33, the elastic bag 2 is fixedly arranged on the first connecting film 32, the first connecting film 32 is a tubular film structure, and the second connecting film 33 is used to block both ends of the first connecting film 32. The second connecting film 33 is connected to the end of the first connecting film 32 on one side and to the baffle 12 on the other side. Specifically, a plurality of connection positions are formed on the second connection film 33, and the second connection film 33 includes a first bending portion 321, a second bending portion 322, and a third bending portion 323. The first bending portion 321, the second bending portion 322, and the third bending portion 323 are connected in sequence, and are folded in sequence and fixed together, so as to form a three-layer membrane structure at the end of the first connection film 32. The first bending portion 321, the second bending portion 322, and the third bending portion 323 are fixed together through the connection position, and the connection position adopts Velcro in this embodiment. Taking the first bending portion 321 and the second bending portion 322 as an example, the first bending portion 321 and the second bending portion 322 are tightly attached to achieve the fixation of the first bending portion 321 and the second bending portion 322. The first connection film 32 is elastic, so that the diameter of the first connection film 32 becomes larger and smaller, and the second connection film 33 changes accordingly. Alternatively, a plurality of connection positions are also provided on the first connection film 32 , and the diameter of the first connection film 32 can be enlarged or reduced by folding the first connection film 32 .

[0051] Therefore, before winding the cotton yarn, the diameter of the first connecting film 32 is in a relatively small state. Then the cotton yarn is collected on the roller body 11. As the length of the collected yarn becomes longer, the thickness of the cotton yarn on the roller body 11 will gradually increase. As the thickness increases, the connection position on the first connecting film 32 and the second connecting film 33 will be pulled apart, so that the diameter of the first connecting film 32 becomes larger, and the second connecting film 33 will also become larger, so that more cotton yarn can be stored. At the beginning of storage, the winding is carried out with a small inner chamber 21, which can better make the elastic bag 2 have a smaller deformation and make the elastic bag 2 abut against the cotton yarn. As more cotton yarn is stored, the first connecting film 32 gradually becomes larger, and the elastic bag 2 is always kept from having a smaller deformation to increase the protection of the elastic bag 2.

[0052] In other specific embodiments, a flexible shell is provided at the crack 31, the flexible shell is connected to the crack 31, and the flexible shell allows the yarn to enter the inner chamber 21. In addition, a fleece layer is provided on the inner wall surface of the connecting chamber to contact the yarn, and the hair on the yarn contacts the fleece layer to prevent the hair from leaking out.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
