Description

Technical Field

[0001] This invention relates to the field of cotton grabbing machine technology, and in particular to a feeding device for cotton quilt production. Background Technology

[0002] The cotton grabber, as a core upstream equipment in the cotton quilt processing production line, mainly consists of a rotary trolley, a beater module, a side panel, and a humidification module. During operation, the side panel holds the cotton bales, and the rotary trolley drives the beater module and humidification module to rotate circumferentially. The beater module continuously grabs the cotton fibers from the surface of the cotton bales during this rotation, while the humidification module continuously sprays water mist onto the surface of the cotton bales to control the humidity of the cotton fibers. These four main parts work together and play a crucial role in grabbing cotton fibers and conveying them to subsequent processes. During the process, the moisture regain of cotton fibers has a significant impact on the opening effect, cotton fiber damage rate, equipment operating efficiency, and subsequent processing quality. When the moisture regain of cotton fibers is too high, the binding effect of moisture can easily cause cotton fibers to entangle and form knots, which not only increases the difficulty of opening but also causes cotton to accumulate in key components such as beaters and dust bars, leading to airflow blockage and forced machine shutdown for cleaning. When the moisture regain is too low, the rigidity of cotton fibers increases, and they are prone to excessive breakage under mechanical impact, producing short fibers of 16mm and below, which directly affects yarn strength and yarn evenness.

[0003] Current processes generally employ humidity control methods such as heating evaporation or spray humidification. Among these, the humidification module often uses a top-mounted atomizing device, which sprays droplets onto the surface of the cotton bale. The droplets then sink and penetrate into the cotton bale. However, due to the compaction of the cotton bale and the surface tension of the droplets, the droplets have difficulty penetrating the cotton layer structure, resulting in a significant humidity gradient between the surface cotton fibers and the deep cotton fibers. This uneven humidity phenomenon directly causes differences in the moisture content of the cotton fiber bundles grabbed by the cotton grabber in a single operation, leading to the dual problems of cotton fiber adhesion and excessive breakage. Summary of the Invention

[0004] This invention provides a feeding device for cotton quilt production, which overcomes the shortcomings of current top-mounted atomizing devices where the droplets produced cannot penetrate the cotton layer structure, resulting in differences in the moisture content of cotton fiber bundles grabbed by the cotton grabber in a single operation, leading to cotton fiber adhesion and excessive breakage.

[0005] Technical solution: A feeding device for cotton quilt production, comprising: A central seat and a surrounding panel, the central seat and the surrounding panel being coaxial, the central seat being equipped with a rotary trolley and a beater module, the rotary trolley being used to drive the beater module to rotate circumferentially about the central axis of the central seat, characterized in that the beater module is fixedly connected to two mounting brackets, the mounting brackets being slidably connected to mounting seats, the two mounting seats being jointly fixedly connected to a transfer shell, the lower side of the transfer shell being provided with an exhaust notch, the mounting seats being fixedly connected to an air guide pipe communicating with the interior of the transfer shell, the air guide pipe communicating with an external humidifier, the two mounting seats being jointly rotatably connected to a cotton pressing cylinder, the transfer shell being located inside the cotton pressing cylinder, the cotton pressing cylinder being provided with multiple air jet holes.

[0006] Furthermore, in the direction from the inside to the outside of the enclosure, the diameter of the air jet holes increases sequentially to accommodate the different linear velocities corresponding to different rotation radii of the cotton pressing cylinder.

[0007] Furthermore, it also includes: Two support plates are fixedly connected to adjacent mounting bases. The support plates are located below the mounting frame. A pressure sensor is fixedly connected between the support plates and the mounting frame to detect the density of the cotton bale and adjust the humidifier power accordingly.

[0008] Furthermore, it also includes: Two elastic strips are slidably and sealed within the vent opening. The elastic strips are in contact with the cotton pressing cylinder. The two elastic strips are jointly fixed to multiple support frames. An elastic net is fixed to the transfer shell along with the two elastic strips. The elastic net is used to maintain the contact state between the two elastic strips and the cotton pressing cylinder. An adjusting column is fixed to the transfer shell through a bracket. The adjusting column is located between the two elastic strips. The two elastic strips and the adjusting column jointly control the flow area of ​​the vent opening.

[0009] Furthermore, there is a gap between the transfer shell and the cotton pressing cylinder.

[0010] Furthermore, the two elastic strips and the adjusting column are jointly fixed with multiple partition plates.

[0011] Furthermore, it also includes: Two fixed seats are respectively fixed to the adjacent mounting seats. The two fixed seats are rotatably connected to a central shaft. The central shaft is fixed with a plurality of circumferentially equidistant fixed strips. All the fixed strips are fixed to a connecting cylinder. The connecting cylinder is fixed with a plurality of circumferentially equidistant slits, the number of which is equal to that of the fixed strips. In each group of slits, they are equidistant along the central axis of the central shaft. The central axis of the slits intersects with and is perpendicular to the central axis of the central shaft.

[0012] Furthermore, the connecting cylinder is made of elastic material, the inner diameter of the connecting cylinder is larger than the outer diameter of the central shaft, and all the fixing strips and all the loosening burrs are staggered.

[0013] Furthermore, the two fixed seats are rotatably connected to a cleaning cylinder, which has a number of strip holes equal to the number of loosening thorns. The loosening thorns slide within adjacent strip holes, and the central axis of the cleaning cylinder is located above the central axis of the central shaft.

[0014] Furthermore, the inner diameter of the cleaning cylinder is equal to the sum of the outer diameter of the connecting cylinder and the axial length of the loosening burr.

[0015] Overall, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects: This invention uses a cotton pressing cylinder to adhere to the surface of the cotton bale and utilizes an exhaust vent to control the flow direction of the water mist, allowing the airflow to carry the water mist directly into the interior of the cotton bale, thereby enhancing the kinetic energy of the droplets and increasing the efficiency of the droplets penetrating into the interior of the cotton bale, reducing the humidity difference of cotton fibers at different depths, and improving the uniformity of the cotton fibers.

[0016] By utilizing the variation in the nozzle diameter, the rotary cotton grabber adapts to the different linear velocities on the inner and outer sides, ensuring that the water mist flow rate of the inner nozzle is less than that of the outer nozzle, thereby promoting a more uniform moisture content in the cotton fibers on both sides of the rotary cotton grabber.

[0017] The reaction force of the cotton fibers on the surface of the cotton bale on the cotton pressing cylinder causes the pressing cylinder to deform. In turn, the deformation of the pressing cylinder causes the elastic strip to deform synchronously at the corresponding position, changing the flow area of ​​the exhaust opening at that point. This allows the high-density cotton fibers to receive more water mist, improving the uniformity of cotton fiber humidification.

[0018] By using the method of opening and piercing the surface of the cotton bale to create microporous channels for the flow of water mist, the obstruction and interception effect of the cotton fibers on the surface of the cotton bale on the water mist is reduced, which promotes the water mist to penetrate into the interior of the cotton bale and reduces the proportion of water mist intercepted by the cotton fibers on the surface of the cotton bale, thereby improving the uniformity of the moisture content of the cotton fibers on the surface of the cotton bale.

[0019] By utilizing the non-coaxial nature of the cleaning cylinder and the central shaft, the opening pin slides back and forth within adjacent slots as it rotates circumferentially around the central axis of the connecting cylinder. The cleaning cylinder blocks cotton fibers wrapped around the opening pin, reducing the probability of cotton fibers wrapping around the opening pin surface and affecting it.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0024] Example 1 This embodiment discloses a feeding device for cotton quilt production, which is used to change the humidification method of cotton bales to improve the uniformity of cotton fiber moisture content.

[0025] Please refer to Figures 1-6A feeding device for cotton quilt production includes: a central seat 1 and a surrounding plate 103. The central seat 1 and the surrounding plate 103 are coaxial. A rotary trolley 101 is mounted on the central seat 1 via a bracket rotatably connected to it. A beater module 102 is mounted on the bracket of the central seat 1 via an electric slide rail. The beater module 102 transports the cotton fibers it grabs to subsequent equipment through a pipe. The central seat 1, the rotary trolley 101, the beater module 102, and the surrounding plate 103 together form a rotary cotton grabber. The rotary trolley 101 and the beater module 102 are existing devices and are not specifically shown in the attached drawings. A microwave humidity sensor (an existing device and not shown in the attached drawings) for real-time monitoring of the surface humidity of the cotton bale is installed on the beater module 102. Two mounting brackets 2 are fixedly connected to the beater module 102. The mounting brackets 2 are located on the front side of the beater module 102. The mounting brackets 2 are slidably connected to the mounting seats 3. The two mounting seats 3 are fixedly connected to the transfer shell 4. The two mounting seats 3 respectively block the openings on the left and right sides of the transfer shell 4. The lower side of the transfer shell 4 is provided with an exhaust port 401. The mounting seats 3 are fixedly connected to the air guide pipe 5, which is connected to the transfer shell 4. The air guide pipe 5 is connected to an external humidifier. The water mist generated by the humidifier is transported to the air guide pipe 5 by the airflow generated by the air pump. The two mounting seats 3 are rotatably connected to the cotton pressing cylinder 6. The transfer shell 4 is located inside the cotton pressing cylinder 6. A bearing is installed between the mounting seats 3 and the cotton pressing cylinder 6, so that the cotton pressing cylinder 6 can roll along the upper side of the cotton bale. The lower side of the cotton pressing cylinder 6 is coplanar with the lower side of the cotton pressing roller in the beater module 102. The cotton pressing cylinder 6 is provided with multiple evenly distributed air jet holes 601.

[0026] The above settings can achieve the following: by pressing the cotton cylinder 6 against the surface of the cotton bale and controlling the flow direction of the water mist using the exhaust vent 401, the airflow carries the water mist directly into the interior of the cotton bale, enhancing the kinetic energy of the droplets, thereby increasing the efficiency of the droplets penetrating into the interior of the cotton bale, reducing the humidity difference of cotton fibers at different depths, and improving the uniformity of the cotton fibers.

[0027] The working principle after adopting the above settings is as follows: In the cotton quilt production process, the cotton grabber gradually transports the cotton fibers in the cotton bales to subsequent equipment for cotton quilt production; the working principle of the above-mentioned device is as follows: The worker places the cotton bales between the partition plate 103 and the center seat 1, and then starts the rotary trolley 101 and the beater module 102 in sequence, and sets the circumferential rotation speed of the rotary trolley 101 and the grabbing speed and cotton feeding amount of the beater module 102 respectively. Then the worker starts the humidifier and the air pump. First, the rotary trolley 101 works and drives the beater module 102 to rotate clockwise circumferentially through the bracket (here, it is used as...). Figure 1(Top view is a rotating perspective) The beater module 102 continuously grips the cotton fibers during rotation. The beater module 102 drives the intermediate shell 4 and the cotton pressing cylinder 6 to rotate circumferentially together through the mounting frame 2 and the mounting base 3. The cotton pressing cylinder 6 contacts the surface of the cotton bale and squeezes the surface cotton fibers of the cotton bale downward (at this time, the function of the cotton pressing cylinder 6 is the same as that of the cotton pressing roller). During this process, the cotton pressing cylinder 6 rotates due to the friction between the cotton bale and the roller. The cotton pressing cylinder 6 drives all the air jet holes 601 to rotate, so that all the air jet holes 601 connect with the exhaust port 401 after rotating to the lower side of the cotton pressing cylinder 6.

[0028] When the worker starts the humidifier and air pump, the power of the humidifier and air pump is set according to factors such as the cotton throughput of the beater module 102, the initial moisture content of the cotton bale, and the type of cotton fiber. This ensures that the airflow imparts enough kinetic energy to the water mist to penetrate the surface of the cotton bale, and that the humidification depth is consistent with the gripping depth of the beater module 102. After the humidifier and air pump are started, they deliver the water mist to the two air ducts 5 and finally into the interior of the transfer shell 4. The pressure inside the transfer shell 4 increases, creating a pressure difference with the interior of the cotton bale. Under the action of this pressure difference, the water mist inside the transfer shell 4 is ejected through the exhaust port 401 and the air jet port 601 connected to it. Since the cotton pressing cylinder 6 is in contact with the surface of the cotton bale, the water mist ejected from the lower air jet port 601 directly enters the cotton bale and, driven by the airflow in the water mist, penetrates into the interior of the cotton bale.

[0029] During the operation of the beater module 102, the humidity sensor monitors the humidity of the cotton bale surface in real time. Based on the difference between the humidity of the cotton bale surface and the ideal cotton fiber humidity (which refers to the cotton fiber humidity when the cotton grabber causes the least damage to the cotton fibers and the probability of cotton fibers entangled and forming knots during operation), the power of the humidifier and air pump is adjusted in real time to make the moisture content of the cotton bale surface more uniform. The airflow assists the water mist to penetrate the cotton fibers on the surface of the cotton bale, accelerates the speed of water mist travel inside the cotton bale, improves the humidification rate of the cotton fibers, and improves the uniformity of the moisture content of the cotton fibers on the surface of the cotton bale.

[0030] Example 2 This embodiment discloses a feeding device for cotton quilt production, which is further optimized based on Embodiment 1.

[0031] Please refer to Figure 2 and Figure 3 In the direction from the inside to the outside of the enclosure 103, the diameter of the jet hole 601 increases sequentially.

[0032] The above settings can adapt to the different linear velocities on the inner and outer sides of the rotary cotton grabber by changing the diameter of the air jet 601, so that the flow rate of water mist in the inner air jet 601 is less than that in the outer air jet 601, thereby promoting the moisture content of cotton fibers on the inner and outer sides of the rotary cotton grabber to be more consistent.

[0033] Example 3 This embodiment discloses a feeding device for cotton quilt production, which, based on Embodiment 1, provides the function of adjusting the water mist flow rate according to the cotton bale density.

[0034] Please refer to Figures 2-4 It also includes: two support plates 7, which are fixedly connected to adjacent mounting bases 3 respectively. The support plates 7 are located below the mounting frame 2, and a pressure sensor 8 is fixedly connected between the support plates 7 and the mounting frame 2.

[0035] The above settings enable the pressure sensor 8 to monitor the density of the cotton bale in contact with the cotton pressing cylinder 6 in real time, thereby adjusting the power of the humidifier and air pump to adapt to changes in the density of the cotton bale and ensure that the air flow rate can drive the water mist to penetrate the surface of the cotton bale.

[0036] During the transport of cotton fibers, the cotton pressing cylinder 6 squeezes the cotton bales downwards, and the cotton bales exert an upward reaction force on the pressing cylinder 6. The pressure sensor 8 records this reaction force in real time. When the reaction force decreases, it indicates that the density of the cotton bales corresponding to the pressing cylinder 6 decreases, meaning the total volume of cotton fibers within the grasping depth is small, and the gaps between the cotton fibers are large. This results in less resistance for water mist moving within the cotton fibers, at which point the power of the humidifier and air pump should be reduced. Conversely, when the reaction force increases, it indicates that the density of the cotton bales corresponding to the pressing cylinder 6 increases, meaning the total volume of cotton fibers within the grasping depth is large, and the gaps between the cotton fibers are large. The small gaps result in greater resistance as the water mist moves within the cotton fibers, increasing the power of the humidifier and air pump. By controlling the power of the humidifier and air pump, the depth of humidification of the cotton fibers by the cotton pressing cylinder 6 becomes more consistent and approximately equal to the depth of the cotton fibers grasped by the beater module 102. This reduces the probability of the cotton fibers at the same location being humidified multiple times (here, "multiple humidification" means that if the depth of a single humidification is greater than the depth of the cotton fibers grasped by the beater module 102, the beater module 102 will humidify the same cotton fiber at the same location every time it rotates one revolution in each direction, which can easily lead to excessively high moisture content in the cotton fibers at that location).

[0037] Example 4 This embodiment discloses a feeding device for cotton quilt production, which, based on embodiment 3, provides the function of adjusting the local water mist flow rate according to the local density of the cotton bale.

[0038] Please refer to Figures 4-9It also includes: two elastic strips 9, both of which are slidably and sealed within the vent opening 401. The elastic strips 9 are made of elastic rubber, and the cotton pressing cylinder 6 is also made of elastic rubber. The lower side of the transfer shell 4 is horizontal, and the transfer shell 4 is made of a cylinder. The outer diameter of the transfer shell 4 is smaller than the inner diameter of the cotton pressing cylinder 6, providing space for the deformation of the cotton pressing cylinder 6. The elastic strips 9 are in contact with the cotton pressing cylinder 6, and the two elastic strips 9 are jointly fixed with multiple equally spaced support frames 10. The support frames 10 are used to maintain the distance between the two elastic strips 9. Regarding the distance and general shape, an elastic net 11 is fixedly connected inside the transfer shell 4. The upper sides of the two elastic strips 9 are fixedly connected to the elastic net 11. The elastic net 11 is made of elastic rubber and provides continuous downward extrusion force to the two elastic strips 9. An adjusting column 12 is fixedly connected inside the transfer shell 4 through a bracket. The adjusting column 12 is located between the two elastic strips 9. In the direction from top to bottom, the positions of the two elastic strips 9 near the adjusting column 12 are provided with inclined surfaces. In the direction from top to bottom, the distance between the two inclined surfaces gradually increases.

[0039] The above settings can achieve the following: the reaction force of the cotton fibers on the surface of the cotton bale on the cotton pressing cylinder 6 causes the cotton pressing cylinder 6 to deform. Then, the deformation of the cotton pressing cylinder 6 causes the corresponding position of the elastic strip 9 to deform synchronously, changing the flow area of ​​the exhaust opening 401 at that location, so that the high-density cotton fibers can receive more water mist and improve the uniformity of cotton fiber humidification.

[0040] The working principle of the above scheme is as follows: During the operation of this device, the water mist inside the transfer shell 4 passes through the gap between the elastic strip 9 and the adjusting column 12 and enters between the two elastic strips 9, and is sprayed out after passing through the adjacent air jet holes 601; as the beater module 102 grabs, the surface of the cotton bale will be in an uneven state. At this time, when the cotton pressing cylinder 6 applies the same squeezing force to the surface of the cotton bale, the density of the originally concave part of the cotton bale is small after compression, so the required water mist volume is small, and the density of the originally convex part of the cotton bale is large after compression, so the required water mist volume is large. The cotton pressing cylinder 6 deforms at corresponding positions according to the different squeezing pressure on the surface of the cotton bale. When the cotton pressing cylinder 6 deforms, it squeezes the two elastic strips 9, causing the two elastic strips 9 to bend upward at the contact point with the deformed part of the cotton pressing cylinder 6. The elastic strips 9 drive the support frame 10 inside to move and stretch the elastic net 11. At this time, the bending position of the elastic strips 9 moves upward relative to the adjusting column 12, increasing the flow area corresponding to the bending position of the elastic strips 9. In this way, the flow rate of water mist is controlled at a fixed point, so that the moisture content of different positions on the surface of the cotton bale tends to be uniform.

[0041] When the cotton pressing cylinder 6 deforms, the reading of the pressure sensor 8 changes accordingly, and the power of the humidifier and air pump is adjusted in real time based on the reading of the pressure sensor 8.

[0042] When the reaction force on the deformed position of the cotton pressing cylinder 6 decreases, the cotton pressing cylinder 6 recovers under its own elasticity. At the same time, the two elastic strips 9 recover under the elasticity of the elastic net 11. The elastic strips 9 drive the support frame 10 to reset, so that the flow area formed by the elastic strips 9 and the adjusting column 12 is restored.

[0043] Example 5 This embodiment discloses a feeding device for cotton quilt production, which is further optimized based on embodiment 4.

[0044] Please refer to Figure 9 Two elastic strips 9 and adjusting column 12 are fixed together with multiple equally spaced partition pieces 13, which are made of silicone.

[0045] The above settings can achieve multiple separate flow channels by using multiple separators 13 and two elastic strips 9 to reduce the impact of local deformation of the elastic strips 9 on the flow area of ​​its surrounding position, and improve the adjustment accuracy of the flow area by the local deformation of the cotton pressing cylinder 6.

[0046] After a pressure difference is generated between the inner and outer sides of the transfer shell 4, the water mist inside the transfer shell 4 enters the multiple flow channels composed of all the partition plates 13 and the two elastic strips 9, and is ejected after passing through the adjacent air jet holes 601. After the cotton pressing cylinder 6 undergoes local deformation, the two elastic strips 9 bend locally, causing the several flow channels corresponding to the bending positions of the two elastic strips 9 to move upward as a whole, thereby increasing the flow area corresponding to the above-mentioned flow channels and reducing the impact on the remaining flow channels in the vicinity.

[0047] Example 6 This embodiment discloses a feeding device for cotton quilt production, which provides the function of opening microporous channels on the surface of cotton bales based on Embodiment 1.

[0048] Please refer to Figures 1-4 and Figure 10 It also includes: two fixed seats 14, which are respectively fixed to adjacent mounting seats 3. The two fixed seats 14 are rotatably connected to a central shaft 15. The central shaft 15 is located on the front side of the cotton pressing cylinder 6. The central shaft 15 is fixed to a plurality of circumferentially equidistant fixed strips 16. All the fixed strips 16 are fixed to a connecting cylinder 17. The connecting cylinder 17 is fixed to a plurality of circumferentially equidistant and equal in number to the fixed strips 16. Each set of opening thorns 18 consists of a plurality of opening thorns 18 equidistantly distributed along the central axis of the central shaft 15. The length of the opening thorns 18 is greater than the single gripping depth of the beater module 102. The central axis of the opening thorns 18 intersects with the central axis of the central shaft 15 and is perpendicular to each other.

[0049] The above settings enable the use of the open 18 to create microporous channels on the surface of the cotton bale for water mist flow, reducing the obstruction and interception effect of the cotton fibers on the surface of the cotton bale on the water mist, promoting the water mist to penetrate into the interior of the cotton bale, reducing the proportion of water mist intercepted by the cotton fibers on the surface of the cotton bale, and improving the uniformity of the moisture content of the cotton fibers on the surface of the cotton bale.

[0050] The working principle of creating microporous channels on the surface of the cotton bale through the above settings is as follows: During the circumferential rotation of the beater module 102, the beater module 102 drives the central shaft 15 to rotate circumferentially through the mounting frame 2, mounting base 3 and fixing base 14. During the circumferential rotation, the loosening punctures 18 penetrate the surface of the cotton bale and break its dense cotton fiber layer, causing the central shaft 15 and connecting cylinder 17 to rotate. Multiple sets of loosening punctures 18 penetrate the surface of the cotton bale in sequence, thus forming microporous channels for water mist to pass through, which facilitates the penetration of water mist into the cotton bale.

[0051] Example 7 This embodiment discloses a feeding device for cotton quilt production, which reduces the probability of damage to cotton fibers caused by the opening needle 18, based on Embodiment 6.

[0052] Please refer to Figure 10 The connecting cylinder 17 is made of elastic material, specifically polyethylene. The inner diameter of the connecting cylinder 17 is larger than the outer diameter of the central shaft 15. All the fixing strips 16 and all the loosening thorns 18 are circumferentially staggered.

[0053] The above settings can utilize the elastic deformation of the connecting cylinder 17 to control the force of the opening thorns 18 pulling the cotton fibers, reducing the probability of cotton fiber breakage caused by the opening thorns 18 pulling the cotton fibers during the removal of the cotton bale. During the circumferential rotation of the connecting cylinder 17, each set of opening thorns 18 sequentially inserts into the cotton bale and sequentially removes the cotton bale. During the removal of the cotton bale by the opening thorns 18, the cotton fibers will be lifted upwards. In this way, while setting up the flow micropores, it also has the effect of loosening the surface cotton fibers, making it easier for the subsequent beater module 102 to grasp the surface cotton fibers. If the reaction force of the cotton fibers on the opening thorns 18 is large during the process of the opening thorns 18 lifting the cotton fibers, the opening thorns 18 will cause the connecting cylinder 17 to undergo local deformation, changing the angle of the opening thorns 18, thereby causing the cotton fibers lifted by the opening thorns 18 to slip off. In this way, the force of the opening thorns 18 on the cotton fibers is controlled, reducing the probability of cotton fiber breakage.

[0054] Example 8 This embodiment discloses a feeding device for cotton quilt production, which provides a function of cleaning the loosening thorns 18 based on embodiment 7.

[0055] Please refer to Figures 2-4 and Figure 10Two fixed seats 14 are rotatably connected to a cleaning cylinder 19. The cleaning cylinder 19 is provided with a number of strip holes 191 equal to the number of opening thorns 18. The width of the strip holes 191 is equal to the width of the opening thorns 18. The opening thorns 18 slide in adjacent strip holes 191. The central axis of the cleaning cylinder 19 is located directly above the central axis of the central shaft 15. The inner diameter of the cleaning cylinder 19 is equal to the sum of the outer diameter of the connecting cylinder 17 and the axial length of the opening thorns 18. The lower side of the cleaning cylinder 19 is on the same horizontal plane as the lower side of the pressing cylinder 6.

[0056] The above settings can achieve the following: by utilizing the non-coaxial nature of the cleaning cylinder 19 and the central shaft 15, the opening burr 18 can slide back and forth in the adjacent strip hole 191 during the circumferential rotation around the central axis of the connecting cylinder 17. The cleaning cylinder 19 can block the cotton fibers wrapped around the opening burr 18, thereby reducing the probability that the cotton fibers wrapped around the surface of the opening burr 18 will affect it.

[0057] During the circumferential rotation of all the opening punctures 18, which drives the connecting cylinder 17 to rotate, the opening punctures 18 drive the cleaning cylinder 19 to rotate through the strip hole 191. Since the cleaning cylinder 19 and the connecting cylinder 17 are not coaxial, the opening punctures 18 will repeatedly extend and retract relative to the adjacent strip hole 191 during the circumferential rotation. When it retracts into the adjacent strip hole 191, the edge of the strip hole 191 blocks the cotton fibers wrapped around the opening punctures 18, causing the cotton fibers to detach from the opening punctures 18. This cleans the opening punctures 18 and prevents the entanglement of cotton fibers from affecting the opening of the micropore channels of the opening punctures 18.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
