[0039] like Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the through grooves 4 are symmetrically distributed on both sides of the device housing 1, the horizontal center line of the through grooves 4 and the horizontal center line of the combing plate 11 are on the same horizontal line, the fixing rod 5 is fixed to the top center part of the fixing plate 6, the positioning grooves 7 are equidistantly distributed on the fixing plate 6, the positioning grooves 7 correspond one-to-one with the combing plate 11 through the positioning rod 8, the first spring 9 is symmetrically distributed on both sides of the positioning rod 8, the first spring 9 corresponds one-to-one with the stop block 10, the end cross-section of the stop block 10 is a right-angled trapezoid, the length of the positioning rod 8 is greater than the thickness of the fixing plate 6, and the cooperation of the positioning rod 8 and the stop block 10 can facilitate and stably disassemble and install the combing plate 11, thereby ensuring the convenience of subsequent cleaning and replacement of the combing plate 11, thereby effectively improving the service life of the combing equipment.

[0040] like Figure 5-Figure 7 and Fig. 9As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the first rubber sheet 13 is distributed at equal angles on the inner wall of the ventilation tube 12, the second rubber sheet 16 is distributed at equal angles on the mounting rod 15, the mounting rod 15 is located at the central part of the ventilation tube 12, the shape and size of the first rubber sheet 13 are the same as the shape and size of the second rubber sheet 16, and the top surface of the filter plate 26 is respectively aligned with the bottom end surface of the ventilation tube 12, the bottom end surface of the first rubber sheet 13, the bottom end surface of the mounting rod 15 and the bottom end surface of the second rubber sheet 16 The connecting rods 27 are equiangularly distributed on the filter plate 26, the third rubber plates 28 are symmetrically distributed on both sides of the connecting rods 27, the cross-sections of the limit blocks 22 and the limit grooves 24 are both rectangular, and the connecting rods 27 can drive the third rubber plates 28 to perform circular motion. Through the fitting contact and kneading between the third rubber plates 28 and each of the first rubber plates 13 and the second rubber plates 16, the impurities and short fibers collected by the suction can be automatically and stably kneaded and gathered, thereby achieving the reduction treatment of the impurities and short fibers.

[0041] Specifically, when the cotton fiber yarn combing device is in use: first, the cotton fiber yarn enters the device housing 1 from the through slot 4 on the left, moves to the outside of the device from the through slot 4 on the right, and moves to the next process for processing in the next process. When the cotton fiber yarn passes through the inside of the device housing 1, the cotton fiber yarn passes through each combing plate 11. At this time, under the action of each combing plate 11, the cotton fiber yarn can be stably combed, and the impurities and short fibers in the cotton fiber bundle can be removed, thereby improving the purity of the raw cotton fiber yarn and the uniformity of the fibers. In addition, the cotton fiber yarn in the entangled state can be untangled according to a certain rule and arranged in a parallel and neat form, which can improve the processing efficiency of the subsequent process and reduce the loss of fibers.

[0042] And in the process of combing the cotton fiber yarn, under the driving action of the servo motor 21 installed at the bottom of the mounting rod 15, the limit block 22 can be driven to rotate through the output shaft, and under the rotation action of the limit block 22, the rotating cylinder 23 can be driven to rotate through the limit groove 24, and then the filter plate 26 and the exhaust fan 25 on the rotating cylinder 23 can be driven to rotate at the same time. At this time, under the continuous rotation action of the exhaust fan 25, the impurities and short fibers combed by the cotton fiber yarn can be sucked through the ventilation tube 12, and can be filtered and collected through the filter plate 26; at the same time, During the rotation of the plate 26, the first rubber plate 13 on the inner wall of the ventilator 12 and the mounting rod 15 on the support rod 14 will not rotate, so the first rubber plate 13 and the second rubber plate 16 on the mounting rod 15 will not rotate, so each first rubber plate 13 and each second rubber plate 16 will block the impurities and short fibers on the filter plate 26. At the same time, during the rotation of the filter plate 26, it can drive each connecting rod 27 to perform a circular motion. At this time, the connecting rod 27 can drive the third rubber plates 28 on both sides to perform a synchronous circular motion, and each third rubber plate 28 During the movement, the third rubber sheet 28 can be in intermittent contact with each first rubber sheet 13 and each second rubber sheet 16, and in the process of contacting each third rubber sheet 28 with each first rubber sheet 13 and each second rubber sheet 16, they can fit each other and squeeze the collected impurities and short fibers. When the third rubber sheet 28 moves away from the first rubber sheet 13 or the second rubber sheet 16, the third rubber sheet 28 and the first rubber sheet 13 and the second rubber sheet 16 will bend under the elasticity of the rubber until they are completely separated. During the complete process, the third rubber sheet The third rubber sheet 28 is always in contact with the first rubber sheet 13 and the second rubber sheet 16, and during the bending and separation process between the third rubber sheet 28 and the first rubber sheet 13 or the second rubber sheet 16, the impurities and short fibers collected by the suction can be automatically and stably kneaded, and the impurities and short fibers collected by the suction can be automatically and stably kneaded and gathered, so as to achieve the reduction of the impurities and short fibers, and then it is convenient for the staff to take and transport the impurities and short fibers in the future, so as to avoid the impurities and short fibers from being scattered into the air during the transportation process, causing environmental pollution and waste of resources;

[0043] After the combing equipment is finished working, the staff can drive the hydraulic rod 2 on the base 3. At this time, under the driving action of the hydraulic rod 2, the device shell 1 can be lifted as a whole, and then the staff can pull the clamping rod 20 on the collection barrel 18 outwards until the clamping rod 20 moves out of the clamping groove 17 on the ventilation cylinder 12. At this time, the collection barrel 18 can move downward until it moves out of the ventilation cylinder 12, completing the disassembly of the collection barrel 18. Then, the staff can take the collection barrel 18 to conveniently and stably take and transport the collected and processed impurities and short fibers above the filter plate 26 inside the collection barrel 18, thereby ensuring the convenience of subsequent recycling and processing of the impurities and short fibers. In the process of the collection barrel 18 moving downward, the limit block 22 on the filter plate 26 can be driven to move downward synchronously, so that the limit block 22 on the output shaft of the servo motor 21 can be disengaged from the limit groove 24 in the rotating barrel 23, ensuring the stability of the disassembly of the collection barrel 18.

[0044] Similarly, when it is necessary to engage and install the collecting barrel 18, it is only necessary to pull the locking rod 20 on the collecting barrel 18 outwards again and sleeve the collecting barrel 18 on the ventilation barrel 12 to reset the collecting barrel 18. Then the staff can loosen the locking rod 20 on the collecting barrel 18. At this time, under the elastic action of the second spring 19, the locking rod 20 can be driven to automatically engage in the locking groove 17 on the ventilation barrel 12, so that the engaging and installing work of the collecting barrel 18 can be completed conveniently. In the process of engaging and installing the collecting barrel 18, the limiting groove 24 on the rotating barrel 23 can be driven to engage with the limiting block 22 on the output shaft of the servo motor 21 to ensure the rotation of the output shaft of the servo motor 21. The limiting block 22 can be used to drive the rotating barrel 23 to rotate stably, thereby ensuring the stability of the subsequent working state of the combing equipment.

[0045] After the combing equipment is finished working, the staff can open the door panel 29, and then the staff can push the stopper 10 to move inside the positioning rod 8. At this time, the stopper 10 will not block the downward movement of the positioning rod 8. Then the staff only needs to pull the combing plate 11 downward to drive the positioning rod 8 to move out of the positioning groove 7 on the fixing plate 6, and complete the disassembly of the combing plate 11, thereby ensuring the convenience of subsequent cleaning and replacement of the combing plate 11. Similarly, when the combing plate 11 needs to be installed, it is only necessary to insert the positioning rod 8 into the positioning groove 7 on the fixing plate 6. During the insertion of the positioning rod 8, the inclined surface of the stopper 10 can contact the fixing plate 6 first. At this time, under the guiding action of the inclined surface of the stopper 10, during the insertion of the positioning rod 8, the stopper 10 can be pushed to automatically move inside the positioning rod 8 until the positioning rod 8 drives the stopper 10 to pass through the positioning groove 7. At this time, under the elastic action of the first spring 9, the stopper 10 can be driven to automatically move outward and reset. At this time, the stopper 10 cooperates with the positioning rod 8 to conveniently complete the clamping installation of the combing plate 11, ensuring the stability of the subsequent working state of the combing plate 11.

[0046] The above embodiments are only used to illustrate the utility model but not to limit the technical solutions described in the utility model. Although the present invention has been described in detail with reference to the above embodiments, the utility model is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the utility model; and all technical solutions and improvements that do not deviate from the spirit and scope of the utility model are included in the scope of the claims of the utility model.
