[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0028] like Figure 1-6As shown, this utility model embodiment provides a combing device for polyester and viscose staple fibers, including a workbench 1, support legs 2 disposed below the workbench 1, and a protective cover 3 disposed above the workbench 1. The protective cover 3 has a door 4 on its front, and an operation panel 41 is fixedly mounted on the door 4. A lifting device 5 is disposed at the top of the protective cover 3, and a combing mechanism 6 is disposed inside the protective cover 3 at the lower end of the lifting device 5. A cleaning mechanism 7 is disposed below the combing mechanism 6, and the cleaning mechanism 7 includes a lead screw 71 disposed between the inner walls of the protective cover 3 below the combing mechanism 6. Multiple guide sleeves 72 are equidistantly disposed on the lead screw 71. A connecting shaft 74 is provided below the guide sleeve 72, and a cleaning brush 75 is connected below the connecting shaft 74. A laser scanning device 76 is fixedly installed above the guide sleeve 72. The laser scanning device 76 is connected to the PLC controller of the operation panel 41 via the same Ethernet. A stepper motor 73 is provided on the outer wall of the protective cover 3. The output end of the stepper motor 73 is connected to the lead screw 71. The stepper motor 73 is connected to the PLC controller of the operation panel 41 via a pulse signal. A suction device 8 is provided on the side wall of the protective cover 3. A collection groove is provided on the side wall of the protective cover 3 away from the suction device 8. A collection box 9 is provided in the collection groove.

[0029] The support leg 2 supports the workbench 1. The protective cover 3 protects the user and reduces noise pollution during the operation of the combing mechanism 6. The cover door 4 opens and closes the protective cover 3. A cleaning mechanism 7 is installed below the combing mechanism 6. A suction device 8 is installed on the side wall of the protective cover 3. A collection box 9 is installed in the collection groove on the side wall of the protective cover 3 away from the suction device 8. The collection box 9 is used to collect fiber impurities. The lifting device 5 is used to move the combing mechanism 6 up and down. The gap of the combing mechanism 6 is adjusted according to the thickness of polyester and viscose staple fibers to improve the practicality of the device. After the combing mechanism 6 stretches, combs, and combines polyester and viscose staple fibers into fiber strips, it first uses the suction device 8 to suck them into the protective cover 3. By periodically changing the cross-sectional area, pressure, or flow rate of the airflow channel, the airflow produces regular intermittent or oscillating airflow, forming a pulsed airflow. The pulsed airflow blows the fiber impurities generated by the combing mechanism 6 during stretching, combing, and combining towards the collection box 9 for dust removal. Then, the cleaning brush 75 moves horizontally. Fiber impurities are swept into the collection box 9. To enable the cleaning brush 75 to move horizontally, the lead screw 71 rotates, driving the guide sleeve 72 to move horizontally. This, in turn, drives the connecting shaft 74 below the guide sleeve 72 and the cleaning brush 75 to move synchronously, allowing the cleaning brush 75 to clean the upper surface of the workbench 1. The number of guide sleeves 72, connecting shafts 74, and cleaning brushes 75 can be set according to actual conditions. Finally, the suction device 8 blows the remaining fiber impurities into the collection box 9 to clean the fiber impurities as much as possible and prevent them from accumulating in the protective cover, which would affect the use of the device. During the process of the combing mechanism 6 stretching, combing, and combining polyester and viscose staple fibers, the laser scanning device 76 monitors parameters such as fiber thickness and density. The scanned thickness and density data are transmitted to the display screen of the operation panel 41 via Ethernet. The PLC controller of the operation panel 41 then controls the output speed of the stepper motor 73 through pulse signals to adjust the speed of the combing mechanism 6, thereby adjusting the fiber parameters and realizing real-time monitoring of the fibers.

[0030] like Figure 3As shown, the lifting device 5 includes a hydraulic cylinder 51, a piston rod 52, and an inverted concave frame 53. The hydraulic cylinder 51 is located at the top of the protective cover 3. One end of the piston rod 52 is connected to the hydraulic cylinder 51, and the other end of the piston rod 52, away from the hydraulic cylinder 51, extends into the protective cover 3 and is connected to the inverted concave frame 53. Bearings 54 are provided on the inner walls of the left and right sides of the inverted concave frame 53. The shafts on both sides of the comb mechanism 6 are rotatably connected to the bearings 54. A drive motor 55 is provided on the outer wall of the inverted concave frame 53, and the drive motor 55 is connected to the shaft of the comb mechanism 6. To adjust the gap of the combing mechanism 6 according to the thickness of polyester and viscose staple fiber and improve the practicality of the device, a lifting device 5 is set to raise and lower the combing mechanism 6. When pressurized oil enters the rodless chamber of the hydraulic cylinder 51, the piston rod 52 is pushed out, driving the inverted concave frame 53 to descend, thus realizing the lowering action of the combing mechanism 6. Conversely, when pressurized oil enters the rod chamber of the hydraulic cylinder 51, the piston rod 52 retracts, driving the inverted concave frame 53 to rise, thus realizing the raising action of the combing mechanism 6 and adjusting the gap of the combing mechanism 6. The drive motor 55 is used to drive the combing mechanism 6 and provide power. A bearing 54 is set between the combing mechanism 6 and the inverted concave frame 53, which not only connects the knitting mechanism 6 and the inverted concave frame 53, but also facilitates the rotation of the combing mechanism 6 inside the inverted concave frame 53.

[0031] like Figure 3 and Figure 6 As shown, the comb mechanism 6 includes a comb cylinder 61. Multiple mounting grooves 63 are formed on the surface of the comb cylinder 61. Needle bars 64 are mounted in the mounting grooves 63 via bolts 65. The needle bars 64 are used for drawing, combing, and combining polyester and viscose staple fibers. To facilitate maintenance and reduce maintenance difficulty, multiple mounting grooves 63 are linearly formed on the surface of the comb cylinder 61, with one needle bar 64 corresponding to one mounting groove 63. The needle bars 64 are threaded into the mounting grooves 63 via bolts 65. When a needle bar 64 malfunctions, only the faulty needle bar 64 needs to be replaced, eliminating the need to replace all needle bars 64, thus reducing maintenance difficulty.

[0032] like Figure 3 As shown, sliding grooves 31 are respectively provided on the left and right inner walls of the protective cover 3. A slider 32 is slidably disposed in the sliding groove 31. A connecting rod 62 is provided between the slider 32 and the outer wall of the inverted concave frame 53. In order to improve the stability of the lifting device 5 during the lifting and lowering process of the comb mechanism 6, sliding grooves 31 are provided on the left and right inner walls of the protective cover 3. The inverted concave frame 53 and the slider 32 in the sliding groove 31 are connected by the connecting rod 62. During the lifting and lowering process of the comb mechanism 6 driven by the lifting device 5, the connecting rod 62 drives the slider 32 to move up and down in the sliding groove, ensuring that the comb mechanism 6 lifts and lowers vertically and improving the stability during the lifting and lowering process.

[0033] like Figure 1 and Figure 3 As shown, the top of the inverted concave frame 53 is provided with two through slots 56. An optical fiber sensor 66 is fixedly mounted on the inverted concave frame 53, and a connecting line 67 is provided on the optical fiber sensor 66. The optical fiber sensor 66 is connected to the operation panel 41 through the connecting line 67. To monitor the tension changes of the fibers during the drafting and combing process in real time, and to avoid problems such as fiber breakage due to excessive tension or entanglement and loosening due to insufficient tension, an optical fiber sensor 66 is installed on the inverted concave frame 53 to monitor the fiber sliver in real time during processing. The connecting line 67 is used to connect the optical fiber sensor 66 to the operation panel 41, transmitting the monitoring data to the display screen of the operation panel 41. Used in conjunction with a laser scanner, this reduces the error in the monitoring data. In addition, the optical fiber sensor 66 can also monitor the needle bar 64 of the combing equipment. By installing an optical fiber sensor near the combing needle, and detecting changes in the vibration frequency or light reflection signal when the needle bar 64 contacts the polyester fiber, the condition of the needle bar 64 can be determined. If an abnormality occurs, timely warning and replacement are provided to prevent wear or breakage of the needle bar 64 after long-term use, which could lead to insufficient fiber combing or equipment malfunction.

[0034] like Figure 5 As shown, the suction device 8 includes a frame 81 that penetrates one side wall of the protective cover 3. A suction fan 82 is installed inside the frame 81. The suction fan 82 is electrically connected to the operation panel 41 via a cable. The frame 81 has an air inlet 83 and an air outlet 84, and the frame 81 gradually tapers from the air inlet 83 to the air outlet 84. A filter screen 85 is installed between the suction fan 82 and the air outlet 84. The suction fan 82 draws external airflow through the air inlet 83 into the frame 81 and then into the protective cover 3 through the air outlet 84. The frame 81 is designed to gradually taper from the air inlet 83 to the air outlet 84, resulting in a more concentrated airflow into the protective cover 3 and better cleaning and dust removal. To prevent impurities in the air from entering the protective cover 3, a filter screen 85 is installed between the suction fan 82 and the air outlet 84 to filter impurities in the air and prevent them from entering the protective cover 3.

[0035] like Figure 2 As shown, a magnetic strip 33 is installed in the collection groove on the side wall of the protective cover 3 away from the suction device 8, and the collection box 9 is an iron collection box. In order to quickly install the collection box 9 in the collection groove of the protective cover 3, a magnetic strip is installed in the collection groove, and the collection box 9 is made of iron, so that the magnetic strip 33 can attract and fix the collection box 9. When separating the collection box 9 from the magnetic strip 33, force can be applied directly to pull the collection box 9 off the magnetic strip 33. The installation and disassembly are convenient and quick.

[0036] The working principle of this embodiment is as follows: After the combing mechanism 6 stretches, combs, and combines polyester and viscose staple fibers into fiber strips, the cover door 3 is opened to remove the fiber strips from the combing mechanism 6. The cover door 3 is then closed, and the suction device 8 draws airflow into the protective cover 3. By periodically changing the cross-sectional area, pressure, or flow rate of the airflow channel, the airflow is made to produce regular intermittent or oscillating airflow, forming a pulsed airflow. The pulsed airflow blows the fiber impurities generated by the combing mechanism 6 during the stretching, combing, and combining process toward the collection box 9 for dust removal. Then, the cleaning brush 75 moves horizontally to sweep the fiber impurities into the collection box 9, so as to clean the fiber impurities as much as possible and prevent the fiber impurities from accumulating in the protective cover and affecting the use of the device.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
