Description

Technical Field

[0001] This invention relates to the field of cotton sample pretreatment technology, and in particular to a cotton sample dispensing device for instrumental testing of cotton, such as HVI. Background Technology

[0002] Cotton, as an important textile raw material, typically requires pre-sample preparation before instrumental testing. This includes sample division, flattening, quantitative sample preparation, and pre-test condition adjustment to ensure the representativeness and consistency of subsequent test results for color grade, micronaire value, and length / strength. Especially in HVI (High Volume Instrument) testing scenarios, cotton samples usually need to be pre-treated and fed separately according to different material levels in the downstream material box. The sample allocation state directly affects the testing efficiency and the stability of the test results.

[0003] In existing technologies, cotton testing samples are mostly transported and pre-treated using conveyor belts or manual sample preparation. For example, Chinese patent document CN108147028B discloses an automatic cotton testing sample transport system that can transport cotton samples from the balancing chamber to the testing chamber. Although the above methods can achieve sample transport, the following problems still exist in actual use: First, cotton samples are easily compacted or locally piled up during transport, making it difficult to meet the requirement of "flat and uniform state" before testing; second, for the sample preparation requirements of different material positions in the HVI testing material frame, existing methods still rely heavily on manual sample separation, manual tearing of cotton, and manual feeding, making it difficult to simultaneously ensure the basic consistency of sample blocks required for color grade testing and the weight control requirements for micronaire and long-strength testing; third, cotton fibers are easy to entangle and scatter, and manual tearing of cotton is not only labor-intensive but also poses a risk of cutting the operator's hands, and the sample consistency is poor. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a distribution device for cotton sample pretreatment, so as to solve the problems in the existing pretreatment of cotton samples that are easy to be compacted, difficult to keep flat and uniform, rely on manual tearing and distribution, and are difficult to adapt to the pretreatment requirements of different test items.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A dispensing device for cotton sample pretreatment includes a dispensing component for dispensing and transferring cotton samples or samples required for different testing items. The dispensing component includes a base and a protective box. The top of the base is fixedly connected to the bottom of the protective box. A central box is rotatably connected inside the protective box. Four placement boxes are fixedly connected in pairs to the outside of the central box. A foot pedal component is provided inside the base to drive the dispensing component to transfer the cotton sample. A lifting component is provided inside the foot pedal component to gather the cotton sample after it is spread out, in conjunction with a cotton tearing component. A cotton tearing component is provided on one side of the top of the protective box to pull the cotton sample into fibers. The dispensing component and the cotton tearing component work together to complete the pretreatment of the cotton sample for testing.

[0006] Optionally, a discharge hole is provided on one side of the protective box, and the size of the discharge hole is adapted to the size of the placement box. The top of the protective box is connected to three flip covers by hinges, and the two adjacent flip covers are arranged vertically. Multiple alignment plates are fixedly connected to the top inside the protective box. The alignment plates are located at the bottom of the flip covers away from the hinges, and the position of the flip covers corresponds to the position of the placement box inside the protective box.

[0007] Optionally, a base plate is rotatably connected to the bottom of one end of the placement box via a shaft, and an inclined slope is provided on the top of the base plate. A rear baffle is fixedly connected to the top of the other end of the placement box. Multiple first springs are fixedly connected inside the rear baffle.

[0008] Optionally, the foot pedal assembly includes a rotating rod rotatably connected inside the base. The top of the rotating rod passes through the top of the base and is fixedly connected to the bottom of the center box. A sleeve is fitted around the bottom of the rotating rod. A fifth spring is installed inside one end of the sleeve, and one end of the fifth spring contacts the bottom end of the rotating rod. A fixing frame is fixedly connected inside the base. The outside of the sleeve is slidably connected to the inside of the fixing frame. A positioning cap is fixedly connected to one side of one end of the sleeve. The outside of the rotating rod has four long slots and four inclined slots. The four long slots are at a 90-degree angle to each other. The two ends of each inclined slot are connected to the top and bottom of two adjacent long slots, respectively. The height of the top of the long slot is higher than the height of the top of the connected inclined slot, and the height of the bottom of the long slot is... The height is lower than the bottom of the connected inclined groove. The bottom of the positioning cap is slidably engaged with a movable bolt. The bottom end of the movable bolt passes through the side wall of the sleeve and is slidably connected to the inside of the long groove. The inside of the positioning cap is fixedly connected with a sixth spring. The top end of the movable bolt is fixedly connected to one end of the sixth spring. A sliding groove is opened on one side of the sleeve. A positioning rod is fixedly connected to one end of the fixed frame. One end of the positioning rod is slidably connected to the inside of the sliding groove. Due to the height difference at the connection between the long groove and the inclined groove, the movable bolt can only move along the track of the long groove to the track of the inclined groove and cannot move in reverse. When the movable bolt moves along the track of the long groove to the inside of the track of the inclined groove, the rotating rod rotates. When the movable bolt moves from the inside of one long groove to the inside of another long groove, the rotating rod rotates 90 degrees.

A pedal is fixedly connected to one side of the rocker that passes through the base. When one end of the rocker moves downward, the gear moves the rack, causing the moving wheel to move upward along the surface of the ramp block.

[0011] Optionally, the base has alignment grooves on its three sides. The lifting assembly includes three L-shaped plates fixedly connected to the bottom of the sleeve, with adjacent L-shaped plates arranged perpendicularly. The positions of the three L-shaped plates correspond to the positions of the flip cover. An elastic cloth is fixedly connected inside the bottom of the protective box. A stop is slidably engaged at the top of the L-shaped plate away from the sleeve. A fourth spring is fixedly connected inside the top of the L-shaped plate. The top of the fourth spring is fixedly connected to the bottom of the stop. The top of the stop is arc-shaped. The elastic coefficient of the fourth spring is greater than that of the first spring. When the top of the stop moves upward against the bottom plate, the top of the bottom plate is parallel to the inside of the box.

[0012] Optionally, the cotton-shredding assembly includes a fixing frame fixedly connected to the top of the protective box. The fixing frame is L-shaped and its position corresponds to the position of the discharge hole. A moving groove is opened inside one end of the fixing frame. A sliding rod is slidably engaged inside the moving groove. A connecting block is fixedly connected to the bottom of the sliding rod. Multiple alignment cylinders are fixedly connected to the bottom of the connecting block. A rake claw is slidably engaged inside the bottom of the alignment cylinder. The positions of the multiple alignment cylinders correspond to the positions of the discharge hole, and the specifications and dimensions of the multiple alignment cylinders are adapted to the dimensions of the internal space of the box. Multiple trapezoidal blocks are fixedly connected inside one end of the discharge hole. The spacing between each pair of trapezoidal blocks is adapted to the thickness of the rake claw. The alignment cylinders, rake claws, and trapezoidal blocks are all made of rubber.

[0013] Optionally, the fixing frame is located at one end of the moving groove and is inclined to the protective box. A counterweight is fixedly connected to one side of the connecting block, and a pull rope is fixedly connected to the other side of the connecting block. A first pulley is rotatably connected to the bottom of one end of the fixing frame. The end of the pull rope away from the connecting block passes through the outside of the first pulley.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up distribution components and cotton tearing components, the cotton samples to be tested can be transported and torn apart, which not only improves the efficiency of pre-testing and reduces manual intervention, but also uses lifting components during the transport process to keep the cotton samples in a loose state, avoiding compaction or excessive dispersion, and ensuring that the sample state is uniform during testing. This not only improves the fluidity of the cotton samples and makes the entire testing process smoother, but also facilitates subsequent sample supply according to the sample loading requirements of testing stations such as HVI.

[0016] By setting up the distribution component, different samples of cotton to be tested can be transferred in batches, avoiding the problems of cotton sample accumulation and mutual interference during pre-testing. At the same time, by opening the flip cover, the pre-segmented cotton samples can be placed inside multiple placement boxes, and the cotton samples are transferred to the discharge position in sequence by rotating, which facilitates subsequent feeding or framing according to the test requirements. Meanwhile, the protective box forms a relatively closed structure to prevent the cotton samples from being contaminated by environmental humidity or impurities.

[0017] By incorporating a foot pedal assembly, the distribution assembly can be driven to rotate. Through the mechanical linkage of the rotating rod, sleeve, and inclined groove, the foot pedal kinetic energy is converted into rotational drive, eliminating reliance on traditional motors. This prevents cotton fibers from entering the motor and causing malfunctions, and also avoids short circuits in high-fiber environments. This fundamentally eliminates electrical fires caused by cotton lint, reducing fire risk and improving equipment safety. During use, stepping on the pedal drives the sleeve to rotate the rotating rod via a movable bolt. The simple structure makes it easy for workers to operate, thereby improving work efficiency.

[0018] By setting up a lifting component, during the cotton sample transfer process, the lifting component directionally pushes the cotton sample, causing it to disperse from a compacted state and then reassemble, forming a more uniform cotton layer. This provides a more stable sample shape for subsequent testing. During use, when the foot pedal component moves the sleeve upward, the L-shaped plate will lift the bottom of one end of the base plate through the bolt. At the same time, when the placement box moves past the top of the bolt, one end of the base plate will descend due to the squeezing action of the telescopic plate. This causes the cotton sample at the top of the base plate to shake, thereby adjusting the cotton sample gap to an appropriate state, avoiding excessive compression or excessive looseness, thus improving the accuracy of the test, and also facilitating subsequent cotton tearing.

[0019] By setting up a cotton tearing component and adopting a mechanical tearing structure, the cotton sample is ensured to be torn evenly without damaging the fiber morphology, providing more representative cotton fiber samples for subsequent testing. At the same time, the component uses a rake claw and a trapezoidal block to tear the cotton sample, which reduces manual intervention, avoids the risk of hand injury to workers, improves work safety, and further enhances the efficiency of cotton sample testing.

[0023] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0024] The following is a detailed description of a dispensing device for cotton sample pretreatment provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0025] like Figures 1 to 12As shown, an embodiment of the present invention provides a dispensing device for cotton sample pretreatment, including a dispensing component. The dispensing component is used to dispense and transfer cotton samples to be tested or samples required for different testing items. The dispensing component includes a base 1 and a protective box 2. The top of the base 1 is fixedly connected to the bottom of the protective box 2. A central box 3 is rotatably connected inside the protective box 2. Four placement boxes 4 are fixedly connected in pairs to the outside of the central box 3. A foot pedal component is provided inside the base 1 to drive the dispensing component to transfer the cotton sample. A lifting component is provided inside the foot pedal component to gather the cotton sample after it is spread out, in conjunction with the subsequent cotton tearing component. A cotton tearing component is provided on one side of the top of the protective box 2 to pull the cotton sample into fibers. The dispensing component and the cotton tearing component work together to complete the pretreatment of the cotton sample for testing. The set distribution and tearing components enable the transport and tearing of cotton samples to be tested, which improves the efficiency of pre-testing and reduces manual intervention. At the same time, the use of the lifting component during the transport process can keep the cotton sample in a loose state, avoiding compaction or excessive dispersion, and ensuring that the sample is in a uniform state during testing. This not only improves the fluidity of the cotton sample and makes the entire testing process smoother, but also facilitates the subsequent sample supply according to the sample loading requirements of testing stations such as HVI.

[0026] like Figures 1 to 5 As shown, a discharge hole 51 is provided on one side of the protective box 2. The size of the discharge hole 51 is compatible with the size of the placement box 4. Three flip covers 11 are rotatably connected to the top of the protective box 2 via hinges, and two adjacent flip covers 11 are arranged vertically. Multiple alignment plates 10 are fixedly connected to the top inside the protective box 2. The position of the alignment plates 10 is located at the bottom of the flip cover 11 away from the hinge. The position of the flip cover 11 corresponds to the position of the placement box 4 inside the protective box 2. The distribution components allow for batch transfer of different portions of the cotton samples to be tested, avoiding sample accumulation. During use, by opening the flip cover 11, the pre-sampled cotton samples are placed from the top of the protective box 2 into multiple placement boxes 4, and then rotated to transfer the samples sequentially to the discharge port 51 for subsequent loading into the HVI material frame or corresponding testing station. In HVI testing applications, the downstream material frame can be set to five positions: positions 1 and 2 are used for color grade testing, position 3 for micron testing, and positions 4 and 5 for length / strength testing. The processed cotton samples are preferably laid flat as a whole. The sample size of positions 1 and 2 is preferably basically the same, the sample weight of position 3 is preferably 9.5g-10.5g, and the sample weight of positions 4 and 5 is preferably 12g-15g.

[0027] like Figures 1 to 6As shown, a base plate 7 is rotatably connected to the bottom of one end of the placement box 4 via a shaft. An inclined slope is provided on the top of the base plate 7. A rear baffle 5 is fixedly connected to the top of the other end of the placement box 4. Multiple first springs 8 are fixedly connected inside the rear baffle 5. A telescopic plate 6 is slidably engaged inside the bottom of the rear baffle 5. The top of the telescopic plate 6 is fixedly connected to the bottom of the first springs 8. The bottom of the telescopic plate 6 is in contact with the top of the lowest end of the base plate 7. With the rear baffle 5, telescopic plate 6, base plate 7, and first spring 8, and with the top of the base plate 7 tilted, when the cotton sample is placed inside the placement box 4, the cotton sample will first gather on one side where the telescopic plate 6 and the base plate 7 connect. This facilitates the lifting component to disperse the cotton sample and also avoids the problem of the cotton sample being thrown out from one end of the placement box 4 when it rotates. At the same time, the setting of the first spring 8 helps the telescopic plate 6 to automatically spring the base plate 7 back to its original position.

[0028] like Figure 1 , Figure 2 , Figure 7 , Figure 11 and Figure 12 As shown, the foot pedal assembly includes a rotating rod 22 rotatably connected inside the base 1. The top of the rotating rod 22 passes through the top of the base 1 and is fixedly connected to the bottom of the center box 3. A sleeve 26 is fitted on the outside of the bottom of the rotating rod 22. A fifth spring is installed inside one end of the sleeve 26, and one end of the fifth spring contacts the bottom end of the rotating rod 22. A fixing frame 21 is fixedly connected inside the base 1. The outside of the sleeve 26 is slidably connected to the inside of the fixing frame 21. A positioning cap 25 is fixedly connected to one side of one end of the sleeve 26. The outside of the rotating rod 22 has four long grooves 23 and four inclined grooves 24. The four long grooves 23 are at a 90-degree angle to each other. The two ends of the inclined grooves 24 are connected to the top and bottom of the two adjacent long grooves 23, respectively. The height of the top of the long groove 23 is higher than the height of the top of the connected inclined groove 24, and the height of the bottom of the long groove 23 is... The height is lower than the bottom of the connected inclined groove 24. The bottom of the positioning cap 25 is slidably engaged with the moving bolt 54. The bottom end of the moving bolt 54 passes through the side wall of the sleeve 26 and is slidably connected to the inside of the long groove 23. The inside of the positioning cap 25 is fixedly connected with the sixth spring. The top end of the moving bolt 54 is fixedly connected to one end of the sixth spring. A sliding groove 27 is opened on one side of the sleeve 26. A positioning rod is fixedly connected to one end of the fixing frame 21. One end of the positioning rod is slidably connected to the inside of the sliding groove 27. The moving bolt 54 moves along the track of the long groove 23 to the connection point with the inclined groove 24. Due to the height difference between the top end of 23 and the top end of 24, when the moving bolt 54 moves along the track of the long groove 23 to the inside of the inclined groove 24, the rotating rod 22 rotates. When the moving bolt 54 moves from the inside of one long groove 23 to the inside of another long groove 23, the rotating rod 22 rotates 90 degrees. The foot pedal assembly drives the distribution assembly to rotate. Through the mechanical linkage of the rotating rod 22, sleeve 26, and inclined groove 24, the foot pedal kinetic energy is converted into rotational drive, eliminating reliance on traditional motors. This prevents cotton fibers from entering the motor and causing malfunctions, and also avoids short circuits in high-fiber environments. This fundamentally eliminates electrical fires caused by cotton lint, reducing fire risk and improving equipment safety. During use, if... Figure 2 and Figure 7 As shown, by stepping on the pedal 12, the mechanism connecting the pedal 12 and the sleeve 26 is driven, moving the sleeve 26 upward. At this time, the sleeve 26 moves vertically through the provided slide groove 27 and positioning rod. Simultaneously, the positioning cap 25, carrying one end of the moving bolt 54, moves upward along the trajectory of the long groove 23. When the moving bolt 54 moves from the inside of the long groove 23 to the top of the inclined groove 24, as... Figure 12 As shown, since the top of the long groove 23 is higher than the top of the inclined groove 24, one end of the movable pin 54 is pressed into the interior of the inclined groove 24 by the rebound of the sixth spring. When the movable pin 54 slides upward inside the long groove 23, the sixth spring is taut. When the movable pin 54 moves to the top of the inclined groove 24, since the top of the long groove 23 is higher than the top of the inclined groove 24, the sixth spring automatically rebounds, causing one end of the movable pin 54 to rebound into the interior of the inclined groove 24 for contact. This ensures that one end of the movable pin 54 remains in contact with both the long groove 23 and the inclined groove 24. By setting the top of the long groove 23 to be higher than the inclined groove 24, as... Figure 12As shown, this design avoids the problem of the movable pin 54 sliding back into the long groove 23 when the force on the sleeve 26 is released. Simultaneously, when the movable pin 54 slides upward inside the long groove 23, the fifth spring inside the sleeve 26 will contract. Then, when one end of the movable pin 54 moves to the top of the inclined groove 24, releasing the pedal 12 releases the force on the sleeve 26, and the fifth spring will automatically rebound. At this point, because the rotating rod 22 is limited by the fixed frame 21, it causes the sleeve 26 to move downward. The sleeve 26, carrying the movable pin 54, will slide inside the inclined groove 24, simultaneously moving along the track of the inclined groove 24 to the bottom of another long groove 23. By setting the bottom of the long groove 23 lower than the bottom of the connected inclined groove 24, the problem of it returning to the previous position can be avoided. Regarding the issue of accessing the interior of the inclined chute 24, and since the adjacent long chute 23 is set at a 90-degree angle, when the moving bolt 54 moves from one long chute 23 to the interior of another long chute 23, the rotating rod 22 will rotate, causing the rotating rod 22 to rotate along with the central box 3. This causes the placement box 4 to rotate 90 degrees, causing the next placement box 4 to rotate to the discharge hole 51, thus facilitating the testing of the cotton sample placed inside the next placement box 4. In this way, multiple placement boxes 4 are rotated sequentially to the front for cotton sample testing, thus avoiding the trouble of having to walk around to find and move them. It should be noted that the specifications and dimensions of the moving bolt 54 are compatible with the specifications and dimensions of the long chute 23 and the inclined chute 24, so that the moving bolt 54 can easily rotate the rotating rod 22.

[0029] like Figure 1 , Figure 2 and Figure 7As shown, a connecting post 29 is fixedly connected to the end of the sleeve 26 away from the rotating rod 22. A fixing plate 28 is rotatably connected to the outside of the connecting post 29. One side of the fixing plate 28 is fixedly connected to the inside of the base 1. A third spring 30 is sleeved on the outside of the connecting post 29. One end of the third spring 30 is fixedly connected to one side of the fixing plate 28, and the other end of the third spring 30 is fixedly connected to the outside of the end of the connecting post 29 away from the fixing plate 28. A moving wheel 31 is installed on the end of the connecting post 29 away from the fixing plate 28. A guide plate 19 is fixedly connected to the inside of the base 1. A slope block 20 is slidably connected to the top of the guide plate 19. The top of the slope block 20 is sloped. The bottom of the moving wheel 31 contacts the top of the slope block 20. A tooth is fixedly connected to one end of the slope block 20. The top of rack 18 is slidably connected to the inside of base 1. The bottom of the inside of base 1 is rotatably connected to gear 17 and rocker 13 via a shaft. The bottom of rack 18 is meshed with one side of gear 17. A connecting plate 16 is fixedly connected to one side of gear 17. One end of connecting plate 16 is rotatably connected to connecting plate 14 via a shaft. One end of connecting plate 14 is rotatably connected to the middle of rocker 13 via a shaft. A second spring 15 is fixedly connected to the top of one end of rocker 13. The top of the second spring 15 is fixedly connected to the inside of base 1. A pedal 12 is fixedly connected to one side of rocker 13 through base 1. When one end of rocker 13 moves downward, gear 17 moves rack 18, causing moving wheel 31 to move upward along the surface of slope block 20. Through the set ramp 20, connecting column 29, and rocker 13 and pedal 12, when the moving sleeve 26 moves upward, as... Figure 2 and Figure 7 As shown, firstly, the worker steps on pedal 12, causing one end of the rocker 13 to move downwards. At this time, connecting plate 14 pulls connecting plate 16 downwards, simultaneously causing gear 17 to rotate. When gear 17 rotates, rack 18 moves, causing guide plate 19 to move to one side of gear 17. At this time, the top of ramp 20 is sloped, causing moving wheel 31 to move along the top of ramp 20. Simultaneously, the bottom of connecting column 29 compresses the third spring 30, causing it to retract. At the same time, connecting column 29 pushes sleeve 26 upwards. When the foot is released, the sleeve 26 automatically descends via the fifth spring, while the rotating rod 22 rotates. Simultaneously, the third spring 30, along with the connecting column 29, automatically returns to its original position, causing the ramp block 20 to return to its initial state. By using a foot pedal to rotate and place the box 4, the structure is simple and easy for workers to operate, thereby improving work efficiency. At the same time, the second spring 15 is in a stretched state when one end of the rocker 13 descends. When the foot is released, the second spring 15 automatically rebounds, causing one end of the rocker 13 to tilt up, making the automatic return of the rocker 13 smoother.

[0030] like Figures 2 to 6 As shown, the base 1 has alignment grooves on its three sides. The lifting assembly includes three L-shaped plates 32 fixedly connected to the bottom of the sleeve 26, and two adjacent L-shaped plates 32 are arranged vertically. The positions of the three L-shaped plates 32 correspond to the positions of the flip cover 11. An elastic cloth 9 is fixedly connected to the inside of the bottom of the protective box 2. A stop 34 is slidably engaged at the top of the L-shaped plate 32 away from the sleeve 26. A fourth spring 33 is fixedly connected to the inside of the top of the L-shaped plate 32. The top of the fourth spring 33 is fixedly connected to the bottom of the stop 34. The top of the stop 34 is arc-shaped. The elastic coefficient of the fourth spring 33 is greater than that of the first spring 8. When the top of the stop 34 pushes against the bottom plate 7 and moves upward, the top of the bottom plate 7 is parallel to the inside of the placement box 4. During cotton sample transfer, the lifting component directionally pushes the cotton sample, dispersing it from a compacted state and causing it to reassemble, forming a more uniform cotton layer. This provides a more stable sample shape for subsequent testing. In use, when the foot pedal component moves the sleeve 26 upwards, the sleeve 26 slides the L-shaped plate 32 within the alignment groove. Simultaneously, the top of the L-shaped plate 32 moves upwards with the stopper 34. Since the force of the fourth spring 33 is greater than that of the first spring 8, the stopper 34 pushes against the elastic cloth 9, contacting the bottom of the connection between the base plate 7 and the telescopic plate 6. This causes one end of the base plate 7 to tilt upwards, causing the cotton sample on top of the base plate 7 to shake upwards and disperse. The tilt height of one end of the base plate 7 is set to be level with the top of the placement box 4, preventing the cotton sample from spilling out of the placement box 4 if the base plate 7 tilts too high. Furthermore, the placement box 4 rotates as the L-shaped plate 32 moves upwards, and the base plate 7 and placement box 4 are connected... There is a gap at the bottom of the joint, and the bottom of the side plate of the placement box 4 is lower than the bottom of the base plate 7. When the side plate of the placement box 4 rotates and contacts the top of the stop 34, the top of the stop 34 is set to be arc-shaped, and the bottom of the stop 34 is equipped with a fourth spring 33. The side plate of the placement box 4 will squeeze the top of the stop 34, and the stop 34 will automatically retract towards the top of the L-shaped plate 32, thereby enabling the placement box 4 to rotate past the top of the stop 34. At the same time, when the placement box 4 rotates past the top of the stop 34, the base plate 7 releases its bottom function. At this time, the first spring 8 automatically rebounds, causing the bottom of the telescopic plate 6 to press down on one end of the base plate 7 again. At this time, the cotton sample will gather again. In this way, the cotton sample will achieve the effect of shaking and gathering multiple times, thereby adjusting the cotton sample gap to a suitable state, thus avoiding the problem of excessive compression or excessive looseness of the cotton sample, thereby improving the accuracy of the test, and also facilitating the subsequent tearing of cotton. At the same time, the elastic cloth 9 is set to maintain the sealing state of the protective box 2.

[0031] like Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, the cotton-shredding assembly includes a fixed frame 35 fixedly connected to the top of the protective box 2. The fixed frame 35 is L-shaped and its position corresponds to the position of the discharge hole 51. A moving groove 47 is opened inside one end of the fixed frame 35. A sliding rod 40 is slidably engaged inside the moving groove 47. A connecting block 36 is fixedly connected to the bottom of the sliding rod 40. Multiple alignment cylinders 37 are fixedly connected to the bottom of the connecting block 36. A rake claw 38 is slidably engaged inside the bottom of the alignment cylinder 37. The positions of the multiple alignment cylinders 37 correspond to the positions of the discharge hole 51, and the specifications and dimensions of the multiple alignment cylinders 37 are adapted to the dimensions of the internal space of the placement box 4. Multiple trapezoidal blocks 52 are fixedly connected inside one end of the discharge hole 51. The spacing between each pair of trapezoidal blocks 52 is adapted to the thickness of the rake claw 38. The materials of the alignment cylinders 37, rake claws 38, and trapezoidal blocks 52 are all rubber. The position of the discharge plate 50 corresponds to the position of the discharge hole 51. The cotton-tearing component employs a mechanical tearing structure to ensure that the cotton sample is uniformly torn without damaging the fiber morphology, providing more representative cotton fiber samples for subsequent testing. This component uses rake claws 38 and trapezoidal blocks 52 in conjunction to tear the cotton sample, reducing manual intervention, avoiding the risk of hand injury to workers, improving work safety, and further enhancing the efficiency of cotton sample testing. When the cotton sample inside the placement box 4 rotates to the discharge hole 51, the limit switch of the slide rod 40 is released. At this time, the connecting block 36, along with the alignment cylinder 37 and rake claws 38, moves downwards, causing the bottom of the rake claws 38 to contact the top of one end of the bottom plate 7. Pulling the connecting block 36 then causes the rake claws 38 to rake the cotton sample out of the placement box 4. Multiple trapezoidal blocks 52 and multiple rake claws 38 pull the cotton sample out between two trapezoidal blocks 52, thus pulling the cotton sample into filaments and avoiding clumping, which is beneficial for subsequent cotton sample testing. Meanwhile, by setting the trapezoidal shape of the trapezoidal blocks 52 and ensuring that the gap between the two trapezoidal blocks 52 matches the specifications and dimensions of the rake claws 38, the trapezoidal shape of the trapezoidal blocks 52 causes the gap between the two trapezoidal blocks 52 to continuously expand from the inside out. When the rake claws 38 rake out cotton samples, since there are many cotton samples, some of the cotton samples can be removed immediately after rakeing, achieving a fibrous effect. At the same time, when the rake claws 38 return to their original position, the trapezoidal blocks 52 scrape off the cotton samples remaining on the outside of the rake claws 38, and the samples are output from the top of the discharge plate 50. Meanwhile, by setting the alignment cylinder 37, rake claw 38, and trapezoidal block 52 to be made of rubber, damage to the cotton sample can be avoided. At the same time, it can also make the cotton sample resilient when output, which is beneficial to subsequent testing. Furthermore, by setting the alignment cylinder 37, when the bottom of the rake claw 38 contacts the top of the base plate 7, since the top of the base plate 7 is sloping, the rake claw 38 can change and expand according to the shape of the top of the base plate 7, thereby ensuring that the bottom of the rake claw 38 is always in close contact with the top of the base plate 7, thus avoiding the problem of cotton sample leakage.

[0032] like Figures 8 to 10 As shown, the fixed frame 35 is located at one end of the moving groove 47 and is inclined to the protective box 2. A counterweight 39 is fixedly connected to one side of the connecting block 36, and a pull rope 42 is fixedly connected to the other side of the connecting block 36. A first pulley 46 is rotatably connected to the bottom of one end of the fixed frame 35. The end of the pull rope 42 away from the connecting block 36 passes through the outside of the first pulley 46. A discharge plate 50 is fixedly connected to the bottom of the protective box 2. With the pull rope 42, counterweight 39, and one end of the fixing frame 35 tilted, when raking out the cotton sample, the pull rope 42 can be pulled first, causing the connecting block 36 to slide along the slide rod 40 inside the moving groove 47, thus facilitating the use by the staff. At the same time, when returning to the original position, simply release the pull rope 42, causing the connecting block 36 to slide down automatically into the placement box 4 under the action of the counterweight 39 and the tilted shape of one end of the fixing frame 35, thus avoiding the trouble of pushing it back and forth.

[0033] like Figures 8 to 10 As shown, a connecting frame 48 is fixedly connected to the top of the fixed frame 35, a second pulley 49 is rotatably connected to the top of the connecting frame 48, a limiting rope 41 is slidably connected to the outside of the second pulley 49, a limiting plate 53 is fixedly connected to the top of the sliding rod 40, the size of the limiting plate 53 is larger than the size of the moving groove 47, one end of the limiting rope 41 is fixedly connected to the top of the limiting plate 53, a rope take-up roller 43 is rotatably connected to the bottom of one end of the fixed frame 35, a crank handle 44 is fixedly connected to one side of the rope take-up roller 43, an insert rod 45 is slidably engaged inside one end of the crank handle 44, a positioning hole is opened on one side of one end of the fixed frame 35, one end of the insert rod 45 is connected to the inside of the positioning hole, and the other end of the limiting rope 41 is fixedly connected to the outside of the rope take-up roller 43. With the setting of the limiting rope 41, crank 44 and insert rod 45, when using the rake claw 38, first pull one end of the insert rod 45 out of the positioning hole on one side of the fixed frame 35. At this time, the limiting rope 41 will be released. Then, by gravity, the connecting block 36 moves downward with the sliding rod 40, thereby causing the bottom of the rake claw 38 to contact the top of the bottom plate 7, so that the rake claw 38 can rake the sample. At the same time, the setting of the limiting plate 53 can prevent the sliding rod 40 from completely sliding out of the moving groove 47. After the cotton sample is tested, the crank 44 is turned to cause the rope take-up roller 43 to take in the rope. At this time, the bottom of the rake claw 38 will move away from the inside of the placement box 4, thereby preventing the rake claw 38 from blocking the rotation of the placement box 4. At the same time, by inserting one end of the insert rod 45 into the positioning hole, the position of the rope take-up roller 43 is fixed, and the position of the rake claw 38 is fixed, thus facilitating the next use of the rake claw 38.
