Description

Technical Field

[0001] The present invention relates to the technical field of cotton sorting, and particularly relates to a cotton sample sorting device for a fiber inspection laboratory. Background Art

[0002] Fiber inspection experiments are usually used for a series of tests to detect the types, properties, and quality of fibers used in textiles. These tests are of great significance for ensuring the quality, safety, and compliance with relevant standards of textiles; in fiber inspection experiments, cotton needs to be sorted before testing, that is, impurities such as soil, grass clippings, and seeds in the cotton sample are removed to avoid the influence of impurities on the accuracy and reliability of cotton test results.

[0003] However, during the sorting process of cotton samples at present, there are usually problems such as difficulty in completely removing impurities and generating dust. With the development of technology, technicians in related fields have also optimized the sorting methods of cotton samples to solve some problems that different consumer groups care about. For more accurate comparison, for example, Chinese Patent No. CN212758724U discloses a cotton sorting table, a row-connected cotton sorting device, and an intelligent control system. Among them, a cotton sorting table includes a table body with a purification unit built in, a table top with an air passage installed at the upper end of the table body, and the purification unit is communicated with the outside through the air passage of the table top. The purification unit includes a multi-stage filtering part and a suction part located at the lower end of the multi-stage filtering part.

[0004] When the above-mentioned prior art is used, the inspector places the cotton sample to be inspected on the table top of the cotton sorting table. Dust-like substances carried by the cotton and tiny short fibers in the cotton enter the purification unit through the air passage. The purification unit adsorbs the sundries, thereby improving the laboratory environment, protecting the health of the staff, and reducing the occurrence of occupational diseases.

[0005] However, there are still some deficiencies in the process of sorting cotton samples by the above-mentioned prior art: 1. Since cotton contains seeds inside and it is difficult to easily blow out or sieve them, the seeds need to be peeled out from the inside of the cotton. However, when the above-mentioned prior art sorts cotton samples, it can only remove impurities and floating dust attached to the surface of the cotton samples by means of air separation and adsorption, so it is difficult to peel out the seeds, resulting in the seeds being likely to affect the subsequent use of the cotton samples, making the cotton unable to be directly used in experiments.

[0006] 2. Also, during the cotton harvesting process, it is easy for soil to mix into the interior of the cotton, and the cotton fibers carry static electricity, which easily attracts light grass clippings. In addition, the grass clippings are easily entangled by the cotton fibers to form a relatively compact structure, and the cotton sample needs to be peeled open to remove the grass clippings and soil. Therefore, only through the existing air separation and adsorption methods, the soil and grass clippings inside the cotton sample cannot be completely removed, which affects the sorting effect and the subsequent experimental progress.

[0007] Therefore, under the viewpoints stated above, there is still room for improvement in the existing cotton sample sorting means. Summary of the Invention

Moreover, the diameter of the driving bevel gear is larger than that of the driven bevel gear. Therefore, the rotation speed of the drive belt is greater than that of the conveyor belt.

[0023] V.

Specific embodiments

[0038] The following is combined with the attached Figures 1 - 11 The embodiments of the present invention will be described in detail.

[0039] The embodiment of the present application discloses a cotton sample sorting device for a fiber inspection laboratory. It should be noted that the cotton sample sorting device of the present application is mainly applied in the process of sorting cotton samples. In terms of technical effects, it can convey cotton samples, then tear the cotton samples, and then remove the impurities on the unfolded cotton samples, so as to realize the rapid sorting of cotton samples and avoid the internal residual impurities of cotton samples from affecting the subsequent experimental effects; especially when tearing cotton samples, it can perform multi-stage tearing, ensure that the cotton samples are torn from the flocculent state to the flat state and expose the internal impurities, and then completely remove the impurities on the surface and inside of the cotton samples by suction; further, the cotton sample sorting device of the present application can also remove the seeds in the cotton samples by reciprocating rubbing, which is convenient to further enhance the experimental effect of the cotton samples.

[0040] Embodiment 1: Refer to Figure 1 And Figure 2As shown in the figure, a cotton sample sorting device for a fiber inspection laboratory includes a bottom plate 1. At the upper end of the bottom plate 1, two support plates 2 are symmetrically arranged along the width direction. On the opposite sides of the two support plates 2, a plurality of rotating shafts 3 are rotatably arranged at equal intervals along the length direction. A transmission belt 4 is sleeved on the outer walls of the plurality of rotating shafts 3. On the side wall of any one of the support plates 2, a positioning motor 5 connected to any one of the rotating shafts 3 is installed through a motor base. On the opposite sides of the two support plates 2, a feeding box 6, a tearing unit 7, and a cleaning unit 8 are sequentially arranged along the length direction, and the feeding box 6, the tearing unit 7, and the cleaning unit 8 are all located above the transmission belt 4.

[0041] Further, in this embodiment, the tearing unit 7 includes a plurality of pulling plates 71 for tearing the cotton sample into a flat shape, and the cleaning unit 8 includes a dust suction belt 81 installed between the two support plates 2 and above the transmission belt 4.

[0042] It should be noted that in this embodiment, the side of the transmission belt 4 close to the feeding box 6 is a feeding area for facilitating the feeding of cotton samples, and the side of the transmission belt 4 far from the feeding box 6 is a discharging area for facilitating the removal of the sorted cotton samples.

[0043] In the specific implementation process, first, start the positioning motor 5. The positioning motor 5 drives the transmission belt 4 to rotate counterclockwise through the rotating shaft 3. Second, put the cotton sample into the feeding box 6. Under the guiding action of the feeding box 6, the cotton sample falls on the transmission belt 4, so that the transmission belt 4 transports the cotton sample from the feeding area to the discharging area. During this period, the tearing unit 7 tears the cotton sample from a flocculent shape into a flat shape to facilitate the unfolding of the cotton sample. Subsequently, the cleaning unit 8 can remove the impurities on the unfolded cotton sample, so as to realize the rapid sorting of the cotton sample and avoid the internal residual impurities of the cotton sample affecting the subsequent experimental results.

[0044] Continue to refer to Figure 1 As shown in the figure, in order to facilitate the tearing unit 7 to tear the cotton sample on the transmission belt 4 into a flat shape, it is necessary to place the cotton sample evenly on the transmission belt 4. Based on this, in this embodiment, the feeding box 6 is optimized accordingly. Specifically, positioning plates 61 are installed between the two outer side walls of the feeding box 6 and the support plates 2. The top of the feeding box 6 expands outward to facilitate the accurate and convenient feeding of the cotton sample into the feeding box 6. A partition plate 62 is installed in the middle of the inner wall of the feeding box 6. The length direction of the partition plate 62 is parallel to the movement direction of the transmission belt 4, and the width of the partition plate 62 gradually increases from top to bottom. The internal space of the feeding box 6 can be partitioned by the partition plate 62, so as to partition the cotton sample in the feeding box 6, avoid the cotton sample sticking into a large flocculent shape and being difficult to fall after being put into the feeding box 6, and ensure that the cotton sample on the upper end of the transmission belt 4 is evenly distributed when the cotton sample falls downward onto the transmission belt 4, preventing the situation of accumulation and difficulty in subsequent tearing.

[0045] Reference Figure 2 , Figure 3 and Figure 5 As shown, in order to completely remove impurities on the surface and inside of the cotton sample, it is necessary to tear the cotton sample apart and remove the impurities inside it. Based on this, a corresponding tearing unit 7 is provided in this embodiment. Specifically, the tearing unit 7 also includes two fixed plates 72 installed on opposite sides of the two support plates 2 and located on the side of the feeding box 6 close to the unloading area. The two fixed plates 72 are arranged along the length direction of the support plate 2. Two linkage shafts 73 are symmetrically rotated along the length direction between the two fixed plates 72, and a positioning shaft 74 is installed in the middle of the opposite sides of the two fixed plates 72. A linkage belt 75 is sleeved between the linkage shaft 73 and the positioning shaft 74. A plurality of pulling plates 71 are evenly arranged on the outer wall of the linkage belt 75. A through hole 76 for making way for the pulling plate 71 is opened on the support plate 2, and a linkage component 77 is arranged between the linkage shaft 73 and the rotating shaft 3.

[0046] Furthermore, in the present embodiment, the two linkage shafts 73 are respectively the first connecting shaft 731 and the second connecting shaft 732, the positioning shaft 74 is fixedly installed on the opposite sides of the two fixed plates 72, and the outer wall of the positioning shaft 74 is rotatably sleeved with a plurality of equally distributed sleeves 741 along its axial direction, and linkage belts 75 are sleeved between the first connecting shaft 731 and the sleeve 741 and between the second connecting shaft 732 and the sleeve 741, and the linkage belts 75 between the first connecting shaft 731 and the plurality of sleeves 741 and the linkage belts 75 between the second connecting shaft 732 and the plurality of sleeves 741 are staggered.

[0047] During the specific implementation process, when the rotating shaft 3 drives the transmission belt 4 to operate and transport the cotton sample, the first connecting shaft 731 and the second connecting shaft 732 are controlled to rotate through the linkage component 77, and the first connecting shaft 731 and the second connecting shaft 732 rotate towards each other, and the first connecting shaft 731 and the second connecting shaft 732 respectively drive the linkage belt 75 on their outer walls to rotate towards each other, so that the upper side of the linkage belt 75 moves toward the side close to the middle of the transmission belt 4, and the lower side of the linkage belt 75 moves toward the side away from the middle of the transmission belt 4, so that the lower side of the linkage belt 75 tears the cotton sample on the upper end of the transmission belt 4 to both sides through the pulling plate 71, and the cotton sample can be torn in multiple stages through multiple groups of linkage belts 75 and pulling plates 71, thereby ensuring that the cotton sample is torn from a clumping state to a flat state and the impurities inside it are exposed, so as to facilitate the complete removal of impurities on its surface and inside, and avoid residual impurities affecting subsequent experimental results.

[0048] It should be noted that the pulling plate 71 provided in this embodiment is composed of a supporting plate 711 and an actuating plate 712. Among them, a plurality of supporting plates 711 are equidistantly arranged on the outer wall of the linkage belt 75. An actuating plate 712 is rotatably arranged on the side of the supporting plate 711 away from the linkage belt 75 through a torsion spring. A carding tooth 713 is installed on the side of the actuating plate 712 away from the supporting plate 711. Through the setting of the torsion spring, the actuating plate 712 is provided with a driving force to rotate towards the side away from the supporting plate 711, and the actuating plate 712 and the supporting plate 711 always remain on the same horizontal plane in the initial state, and the actuating plate 712 can rotate adaptively when it comes into contact with the transmission belt 4, and then rebound and reset under the action of the torsion spring to avoid interference.

[0049] Referring to Figure 5 and Figure 6 As shown, since cotton will undergo a small amount of rebound and reset after being deformed by an external force, in order to prevent the reset cotton sample from taking back impurities into the interior again, it is necessary to perform corresponding limiting on the torn cotton sample. Based on this, in this embodiment, two limiting rings 41 are symmetrically arranged on the outer wall of the transmission belt 4 along the width direction. The limiting rings 41 are made of flexible material and have the same contour as the transmission belt 4. Two partition bars 42 are equidistantly arranged on the opposite sides of the two limiting rings 41. A material distribution area for holding the cotton sample is formed between the limiting ring 41 and the adjacent two partition bars 42. Anti-slip pads 43 are installed on the opposite sides of the adjacent two partition bars 42. A plurality of card slots 44 are equidistantly opened on the anti-slip pad 43 along the length direction, and the card slots 44 are perpendicular to the transmission belt 4.

[0050] In the specific implementation process, when the cotton sample falls from the feeding box 6 onto the transmission belt 4, the cotton sample enters the material distribution area. When the linkage belt 75 drives the carding teeth 713 to tear the cotton sample through the actuating plate 712, it can press the cotton sample downward, so that the cotton sample unfolds in the material distribution area. After the cotton sample unfolds, it can be limited under the action of the anti-slip pad 43 and the card slots 44, avoiding the rebound and reset of the cotton sample and affecting the subsequent impurity removal effect.

[0051] Referring to Figure 2 、 Figure 4 and Figure 5 As shown, in order to improve the sorting efficiency of the cotton sample, it is necessary for the linkage belt 75 to move synchronously with the transmission belt 4, so that while the transmission belt 4 conveys the cotton sample, the linkage belt 75 drives the pulling plate 71 to tear the cotton sample. Based on this, a linkage component 77 is also provided in this embodiment. Specifically, the linkage component 77 includes a support plate 771. Two support plates 771 are symmetrically arranged along the length direction at the lower end of the fixed plate 72 near the middle rotating shaft 3 of the support plate 2. A limiting shaft 772 is rotatably arranged on the support plate 771. The two limiting shafts 772 are respectively connected to its first connecting shaft 731 and second connecting shaft 732 through belt drives.

[0052] Further, in this embodiment, a linkage bevel gear 773 is fixedly sleeved on the outer wall of the limit shaft 772, and two driving bevel gears 774 meshing with the linkage bevel gear 773 are symmetrically and fixedly sleeved on the outer wall of the rotating shaft 3 along the axial direction on one side close to the limit shaft 772.

[0053] In the specific implementation process, when the rotating shaft 3 drives the driving bevel gear 774 to rotate counterclockwise, the cooperation between the driving bevel gear 774 and the linkage bevel gear 773 can drive the first connecting shaft 731 and the second connecting shaft 732 to rotate towards each other, so that the first connecting shaft 731 and the second connecting shaft 732 respectively drive the linkage belts 75 on their outer walls to rotate synchronously (shown in Figure 5 ), so as to facilitate the tearing treatment of the cotton sample.

[0054] It should be noted that the diameter of the driving bevel gear 774 is larger than that of the linkage bevel gear 773. Therefore, the rotation speed of the driving bevel gear 774 is less than that of the linkage bevel gear 773, that is, the rotation speed of the linkage belt 75 is greater than that of the transmission belt 4. Thus, when the transmission belt 4 conveys the cotton sample, the linkage belt 75 can quickly tear the cotton sample through the actuating plate 712 to enhance the unfolding effect of the cotton sample.

[0055] Refer to Figure 7 and Figure 8 As shown, in order to facilitate the removal of impurities exposed on the cotton sample, an impurity removal unit 8 is further provided in this embodiment. Specifically, the impurity removal unit 8 further includes a horizontal plate 82 installed on the opposite sides of the two support plates 2. A dust suction belt 81 covers the outside of the horizontal plate 82. Rubber rollers 83 are rotatably arranged between the two side walls in the length direction of the horizontal plate 82 and the inner wall of the dust suction belt 81. Both ends of the dust suction belt 81 are movably abutted against a support plate 84. A dust collection box 85 covering the upper end of the dust suction belt 81 is installed on the support plate 84. Two rotating rollers 86 for supporting the dust suction belt 81 are rotatably penetrated through the support plate 84. The two rotating rollers 86 are symmetrically distributed up and down. The dust suction belt 81 can be supported by multiple rotating rollers 86. A stabilizing shaft 87 is fixedly penetrated through the rotating roller 86. The stabilizing shaft 87 rotates through the support plate 2 and extends to the outside. The two stabilizing shafts 87 on the same side of the dust suction belt 81 are connected by belt drive.

[0056] Further, in this embodiment, the lower stabilizing shaft 87 and the rotating shaft 3 close to it are connected by belt drive. A plurality of dust suction holes 88 are evenly arranged on the outer wall of the dust suction belt 81. Two air pumps 89 are symmetrically installed on the horizontal plate 82 along the length direction; the air suction end of the air pump 89 extends downward, and the air outlet end of the air pump 89 extends upward. The horizontal plate 82 can divide the upper and lower sides of the dust suction belt 81 into a discharge area and an aggregate area.

[0057] In the specific implementation process, when the rotating shaft 3 drives the conveyor belt 4 to rotate counterclockwise, the stabilizing shaft 87 is driven to rotate synchronously. The stabilizing shaft 87 drives the dust suction belt 81 to rotate counterclockwise through the roller 86. At the same time, the air pump 89 is started. The air pump 89 sucks out the air between the horizontal plate 82 and the dust suction belt 81 below it and discharges it between the horizontal plate 82 and the dust suction belt 81 above it. Thus, the aggregate area of the dust suction belt 81 is always in a negative pressure state. When the conveyor belt 4 transports the unfolded cotton sample below the dust suction belt 81, the dust suction belt 81 comes into contact with the cotton sample. Subsequently, the dust suction belt 81 sucks out the impurities in the cotton sample through the dust suction holes 88, and the unfolded cotton sample can expose the impurities, thereby improving the sorting efficiency of the cotton sample.

[0058] Referring Figure 8 As shown, in order to improve the use effect of the dust suction belt 81 and the dust suction holes 88, it is necessary to discharge the impurities remaining in the dust suction holes 88 in a timely manner. Based on this, in this embodiment, the dust collection box 85 is installed between the two support plates 84. The lower end of the dust collection box 85 has two vertical sections symmetrically distributed along the dust suction belt 81. A sealing roller 851 is rotatably arranged between the vertical section and the dust suction belt 81. The top of the dust collection box 85 is rotatably connected to one of the vertical sections, and the top of the dust collection box 85 is clamped to the other vertical section.

[0059] In the specific implementation process, when the dust suction belt 81 moves into the dust collection box 85, the air pump 89 discharges air into the discharge area, and the air flow blows the impurities in the dust suction holes 88 into the dust collection box 85 for collection. When the impurities in the dust collection box 85 are collected to a certain amount, the top of the dust collection box 85 is opened, so as to facilitate taking out the impurities inside it.

[0060] It should be noted that the diameter of the dust suction hole 88 gradually decreases towards the side closer to the inside of the dust suction belt 81, and a blocking net is installed on the inner wall of the dust suction hole 88 closer to the inside of the dust suction hole 88. The blocking net can block the dust suction hole 88, so that the impurities are collected in the dust suction hole 88, preventing the impurities from entering the discharge area or the aggregate area from the dust suction hole 88. When the dust suction belt 81 moves above the discharge area, the air pump 89 can quickly blow out the impurities in the dust suction holes 88, thereby realizing the rapid sorting of the cotton sample and the impurities.

[0061] Embodiment Two: Referring Figure 9 、 Figure 10 and Figure 11As shown in the figure, on the basis of the first embodiment, in order to further enhance the subsequent experimental effect of the cotton sample, it is necessary to further remove the seeds in the cotton sample. Based on this, in this embodiment, a corresponding seed stripping unit 9 is also provided. Specifically, the seed stripping unit 9 includes an auxiliary shaft 91 rotatably installed between two support plates 2. The auxiliary shaft 91 is located on the side of the dust suction belt 81 away from the feeding box 6 and above the transmission belt 4. The auxiliary shaft 91 is connected to the rotating shaft 3 on its adjacent side by a belt drive. A socket cylinder 92 is slidably sleeved on the outer wall of the auxiliary shaft 91. The auxiliary shaft 91 and the socket cylinder 92 can only slide relative to each other and cannot rotate relative to each other. A plurality of annularly distributed receiving grooves 93 are evenly formed on the outer wall of the socket cylinder 92. A top strip 94 is slidably arranged in the receiving groove 93. A plurality of pushing spring rods 95 are installed between the top strip 94 and the side wall of the receiving groove 93 close to the auxiliary shaft 91. A plurality of stripping blocks 96 are equidistantly arranged along the length direction on the side of the top strip 94 away from the pushing spring rods 95. A plurality of blanking holes are evenly formed in the transmission belt 4. An inverted V-shaped guide frame is installed between the two support plates 2. A discharge hole flush with the V-shaped guide frame is formed in the support plate 2.

[0062] It should be noted that the pushing spring rod 95 always exerts a pushing force on the top strip 94, so that the top strip 94 extends out of the receiving groove 93 in the initial state.

[0063] Furthermore, in this embodiment, connection rings 97 are fixedly installed at both ends of the socket cylinder 92. An arc-shaped protrusion 98 is arranged on the side of the connection ring 97 away from the socket cylinder 92. The arc-shaped protrusions 98 of the two connection rings 97 are staggered. Positioning columns 99 matching the arc-shaped protrusions 98 are installed on the opposite sides of the two support plates 2. The two positioning columns 99 are staggered.

[0064] In the specific implementation process, when the rotating shaft 3 rotates, it drives the auxiliary shaft 91 and the socket cylinder 92 to rotate synchronously. The socket cylinder 92 drives the connection ring 97 to rotate synchronously. Since the positioning column 99 is in a fixed state, when the connection ring 97 drives the arc-shaped protrusion 98 to contact the positioning column 99, it can receive a squeezing force. Therefore, the socket cylinder 92 moves in the opposite direction under the action of the squeezing force. Also, since the two arc-shaped protrusions 98 and the two positioning columns 99 are staggered respectively, the socket cylinder 92 is successively subjected to squeezing forces at both ends, so that the socket cylinder 92 reciprocates during rotation.

[0065] When the transmission belt 4 conveys the cotton sample to the lower part of the socket cylinder 92, the top strip 94 is pushed out to the side away from the auxiliary shaft 91 under the action of the pushing spring rod 95. The socket cylinder 92 drives the top strip 94 and the stripping blocks 96 to rub the unfolded cotton sample reciprocally, so as to rub out the seeds in the cotton sample and drop them through the blanking holes onto the V-shaped guide frame, so that the seeds pass through the discharge hole along the V-shaped guide frame, thereby realizing the removal of cotton seeds and facilitating the enhancement of the experimental effect of the cotton sample.

[0066] During operation: Step 1: First, start the positioning motor 5. The positioning motor 5 drives the conveyor belt 4 to rotate counterclockwise through the rotating shaft 3. Secondly, put the cotton sample into the feeding box 6. Under the guiding action of the feeding box 6, the cotton sample falls on the conveyor belt 4, so that the conveyor belt 4 transports the cotton sample from the loading area to the unloading area.

[0067] Step 2: When the rotating shaft 3 drives the conveyor belt 4 to operate and transport the cotton sample, it drives the driving bevel gear 774 to rotate counterclockwise. Through the cooperation between the driving bevel gear 774 and the linkage bevel gear 773, the first connecting shaft 731 and the second connecting shaft 732 can be driven to rotate towards each other, so that the first connecting shaft 731 and the second connecting shaft 732 respectively drive the linkage belts 75 on their outer walls to rotate synchronously. The lower side of the linkage belt 75 tears the cotton sample at the upper end of the conveyor belt 4 to both sides through the pulling plate 71. And through multiple groups of linkage belts 75 and pulling plates 71, the cotton sample can be torn at multiple levels, so as to ensure that the cotton sample is torn from a tufted shape to a flat shape and the impurities inside are exposed, which is convenient to completely remove the impurities on its surface and inside, and avoid the remaining impurities affecting the subsequent experimental results.

[0068] Step 3: When the linkage belt 75 drives the comb teeth 713 to tear the cotton sample through the actuator plate 712, it can press the cotton sample downward, so that the cotton sample unfolds in the material distribution area. After the cotton sample unfolds, it can be limited under the action of the anti-slip pad 43 and the card slot 44, avoiding the cotton sample from rebounding and resetting and affecting the subsequent impurity removal effect.

[0069] Step 4: During the process of the rotating shaft 3 driving the conveyor belt 4 to rotate counterclockwise, it drives the stabilizing shaft 87 to rotate synchronously. The stabilizing shaft 87 drives the dust suction belt 81 to rotate counterclockwise through the roller 86. At the same time, start the air pump 89. The air pump 89 sucks out the air in the aggregate area of the dust suction belt 81, so that the aggregate area is in a negative pressure state; when the conveyor belt 4 transports the unfolded cotton sample to the lower part of the dust suction belt 81, the dust suction belt 81 contacts the cotton sample, and then the dust suction belt 81 sucks out the impurities in the cotton sample through the dust suction holes 88, and the unfolded cotton sample can expose the impurities, so as to improve the sorting efficiency of the cotton sample.

[0070] When the dust suction belt 81 moves into the dust collection box 85, the air pump 89 discharges air into the discharge area, and the air flow blows the impurities in the dust suction holes 88 into the dust collection box 85 for collection. When the impurities in the dust collection box 85 are collected to a certain amount, open the top of the dust collection box 85, so as to facilitate taking out the impurities inside.

[0071] Step 5: During the rotation of the rotating shaft 3, the auxiliary shaft 91 and the socket cylinder 92 are driven to rotate synchronously. The socket cylinder 92 drives the connecting ring 97 to rotate synchronously. When the arc-shaped protrusion 98 driven by the connecting ring 97 contacts the positioning post 99, it can receive a squeezing force. Thus, the socket cylinder 92 moves in the opposite direction under the action of the squeezing force, and the two ends of the socket cylinder 92 are successively subjected to the squeezing force. Therefore, the socket cylinder 92 reciprocates during the rotation and drives the ejecting strip 94 and the peeling block 96 to rub the unfolded cotton sample reciprocally, so as to rub out the seeds in the cotton sample and make them fall onto the V-shaped guide frame through the blanking hole, enabling the seeds to be discharged through the discharge hole along the V-shaped guide frame, thereby realizing the removal of cotton seeds and facilitating the enhancement of the experimental effect of the cotton sample.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
