Abstract
Description
Technical Field
[0001] This application relates to the field of cotton inlet pipe technology for multi-compartment machines, specifically to a cotton inlet pipe for preventing blockage in multi-compartment machines. Background Technology
[0002] Multi-bin machines are key equipment in the opening and cleaning process of modern textiles. They mainly use airflow to evenly distribute pre-treated fibers into multiple parallel cotton storage bins to achieve thorough mixing of the fibers and provide a uniform cotton flow for subsequent spinning. This is a core step in ensuring the quality of yarn.
[0003] However, in existing multi-compartment cotton inlet pipes, there is usually a step or right angle transition at the connection between the inlet pipe and the distribution channel. The airflow that transports the fibers is prone to become turbulent at this point, causing some fibers to break away from the main airflow and continuously entangle and accumulate in the corner, forming a blockage. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a method for preventing blockages in the cotton inlet pipe of a multi-compartment machine. This method has the advantage of reducing the formation of blockages and solves the problem that in existing multi-compartment machine cotton inlet pipes, there is usually a step or right angle transition at the connection between the cotton inlet pipe and the cotton distribution channel. The airflow that transports fibers is prone to become turbulent at this point, causing some fibers to break away from the main airflow and continuously entangle and accumulate in the corner, forming a blockage.
[0005] This application provides a technical solution for an anti-clogging cotton inlet pipe for a multi-compartment machine, comprising a cotton distribution pipe and a cotton inlet pipe. A connecting pipe is fixedly connected to one side of the cotton distribution pipe, and a first connecting frame is fixedly connected to the end of the connecting pipe away from the cotton distribution pipe. Multiple first through holes arranged in a rectangular array are provided inside the first connecting frame. Two gaskets arranged in a mirror-image configuration are fixedly connected to one side of the first connecting frame, and each of the two gaskets has a second through hole. L-shaped baffles are provided on both sides inside the connecting pipe, and two third through holes are provided on the surface of each of the two L-shaped baffles. A second connecting frame is fixedly connected to one side of the cotton inlet pipe, and multiple connecting bolts arranged in a rectangular array are slidably connected inside the second connecting frame.
[0006] By adopting the above technical solution, the airflow turbulence at the right-angle transition between the cotton inlet pipe and the cotton distribution channel can be improved through the setting of two gaskets and L-shaped baffles. When cotton is conveyed into the cotton distribution channel by airflow, the two L-shaped baffles can gather the airflow and guide the cotton flow, reducing airflow turbulence at the right-angle transition between the cotton inlet pipe and the cotton distribution channel. This avoids fiber blockage at the right-angle transition between the cotton distribution channel and the cotton inlet channel, optimizing the cotton inlet process. During operation, cotton enters the connecting pipe from the cotton inlet pipe. The L-shaped baffles guide the cotton flow and prevent cotton from concentrating and clogging at the right-angle transition of the cotton distribution channel, allowing the cotton flow to enter the cotton distribution pipe more evenly. At the same time, the bolted connection structure facilitates the installation, disassembly, and subsequent maintenance of the device. This device, through the setting of two L-shaped baffles, optimizes the cotton inlet process of the multi-compartment machine, reduces congestion problems, and improves the overall operational stability.
[0007] Preferably, a spark detector is fixedly connected to the upper end of the cotton inlet pipe, a control box is fixedly connected to one side of the cotton inlet pipe, a connecting wire is fixedly connected to one side of the upper end of the control box, and an alarm light is fixedly connected to the side of the upper end of the control box away from the connecting wire.
[0008] By adopting the above technical solution, a spark detector is installed at the upper end of the cotton inlet pipe, and a control box is equipped on one side of the cotton inlet pipe. The spark detector and the control box are connected by connecting wires, and an alarm light is installed on the control box. During operation, the spark detector can monitor in real time whether sparks are generated during the cotton conveying process inside the cotton inlet pipe. Once a spark is detected, it will transmit the signal to the control box through the connecting wire. After receiving the signal, the control box will trigger the alarm light to start, promptly issuing a safety warning to the staff. This allows the staff to quickly detect and deal with potential fire hazards, avoiding safety accidents caused by sparks, thereby providing a safety guarantee for the operation of the cotton inlet pipe of the multi-compartment machine.
[0009] Preferably, one side of the cotton distribution pipe is fixedly connected to a plurality of observation windows arranged in a linear array.
[0010] By adopting the above technical solution, and by setting multiple observation windows in a straight array on one side of the cotton distribution pipe, the staff can directly observe the flow of cotton inside the cotton distribution pipe through the windows without disassembling the pipe or stopping the machine. Once an abnormality is detected, the location of the problem can be quickly determined and targeted measures can be taken.
[0011] Preferably, both gaskets and the L-shaped baffle are disposed between the connecting pipe and the cotton inlet pipe.
[0012] By adopting the above technical solution, by placing two gaskets and an L-shaped baffle between the connecting pipe and the cotton inlet pipe, the gaskets can fill the gap at the connection between the connecting pipe and the cotton inlet pipe during assembly, reducing airflow leakage caused by loose connection and preventing airflow leakage from affecting the stability of cotton flow. At the same time, the L-shaped baffle fixes one side of the short side between the connecting pipe and the cotton inlet pipe, guiding the cotton flow when it enters the right-angle transition area, reducing cotton flow turbulence that may be caused at the right-angle transition, and preventing cotton fibers from accumulating and clogging at the joint.
[0013] Preferably, each of the plurality of connecting bolts has a nut threadedly connected to one end of the first through hole, and the plurality of connecting bolts are disposed inside the second and third through holes.
[0014] By adopting the above technical solution, multiple connecting bolts are sequentially passed through the second through hole of the gasket and the third through hole of the baffle, and a nut is threaded through the first through hole of the first connecting frame. This allows the connecting pipe and the cotton inlet pipe to be tightly fixed through the first and second connecting frames. At the same time, the baffle and gasket are firmly clamped between the connecting pipe and the cotton inlet pipe, ensuring that they will not shift or loosen when cotton flow impacts or equipment operating vibrations. Furthermore, when maintenance is required, the bolts can be removed to quickly separate the components, facilitating the inspection or replacement of the baffle, gasket, etc.
[0015] Preferably, one end of each of the two L-shaped baffles passes through the inside of the connecting pipe and extends into the cotton distribution pipe.
[0016] By adopting the above technical solution, by passing one end of the two L-shaped baffles through the connecting pipe and extending them into the cotton distribution pipe, when cotton enters the connecting pipe from the cotton inlet pipe, the L-shaped baffles can play a role in the transition area where the cotton flow is about to enter the cotton distribution pipe. The part extending into the cotton distribution pipe can directly guide the cotton flow entering this area, avoid cotton from concentrating on one side of the cotton distribution pipe, reduce congestion in the cotton distribution pipe, and ensure the smoothness of cotton transportation.
[0017] Preferably, the end of the connecting wire furthest from the control box is fixedly connected to the spark detector, and the spark detector is electrically connected to the control box.
[0018] By adopting the above technical solution, the spark detector and the control box are electrically connected by fixing the end of the connecting wire away from the control box. When the spark detector detects a spark in the cotton inlet pipe, it can quickly transmit the signal to the control box through the connecting wire, so that the control box can receive and process the signal in time, thereby triggering the alarm light to issue a warning, ensuring that the staff can quickly know the safety hazards in the pipe and prevent safety accidents caused by sparks.
[0019] Preferably, the detection end of the spark detector is installed through the upper end of the cotton inlet pipe.
[0020] By adopting the above technical solution, the detection end of the spark detector is installed through the upper end of the cotton inlet pipe, allowing the detection end to directly contact the cotton conveying environment inside the cotton inlet pipe. When sparks are generated due to friction or other reasons during the flow of cotton in the pipe, the detection end can directly capture the spark signal, ensuring that the spark detector can quickly and accurately monitor potential safety hazards in the pipe. This provides timely and reliable basis for the control box to trigger alarms, further improving the safety of the cotton inlet pipe operation.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] This anti-clogging multi-compartment machine cotton inlet pipe uses a connecting pipe between the cotton distribution pipe and the cotton inlet pipe. A combination of a first connecting frame, a second connecting frame, and connecting bolts and nuts securely clamps a gasket and an L-shaped baffle between the connecting pipe and the cotton inlet pipe. This ensures a tight pipe connection to reduce airflow leakage and allows for easy maintenance through bolt removal and installation. One end of the L-shaped baffle extends into the cotton distribution pipe, effectively guiding the cotton flow at the right-angle transition area after the cotton enters the connecting pipe from the cotton inlet pipe. This concentrates the airflow and cotton flow, preventing the cotton from concentrating in the cotton distribution pipe due to inertia. To prevent congestion on one side, a spark detector at the top of the cotton inlet pipe extends directly into the pipe, monitoring potential sparks during transport in real time. The signal is transmitted to the control box via a connecting wire, triggering an alarm light to promptly alert staff and prevent accidents. Multiple observation windows on one side of the cotton distribution pipe allow staff to visually observe the internal cotton flow without stopping the machine, facilitating timely detection and handling of abnormalities. The device also reduces airflow turbulence at the right-angle transition between the cotton inlet pipe and the cotton distribution channel by using two L-shaped baffles, thus minimizing the occurrence of cotton blockage.

Detailed Implementation
[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 The following is a detailed description of the preferred options for this application.
[0031] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 The system includes a cotton distribution pipe 1 and a cotton inlet pipe 9. A connecting pipe 2 is fixedly connected to one side of the cotton distribution pipe 1. A first connecting frame 3 is fixedly connected to the end of the connecting pipe 2 away from the cotton distribution pipe 1. Multiple first through holes 4 arranged in a rectangular array are provided inside the first connecting frame 3. Two gaskets 5 arranged in a mirror distribution are fixedly connected to one side of the first connecting frame 3. The two gaskets 5 can increase the airtightness of the connection between the cotton distribution pipe 1 and the cotton inlet pipe 9. A second through hole 6 is provided inside each of the two gaskets 5. L-shaped baffles 7 are provided on both sides inside the connecting pipe 2. The two L-shaped baffles 7 can gather the airflow and guide the cotton flow, reduce the airflow turbulence at the right angle transition between the cotton inlet pipe and the cotton distribution channel, and avoid the phenomenon of fiber blockage at the right angle transition between the cotton distribution channel and the cotton inlet channel, thus optimizing the cotton inlet process. Two third through holes 8 are provided on the surface of each of the two L-shaped baffles 7. A second connecting frame 10 is fixedly connected to one side of the cotton inlet pipe 9. Multiple connecting bolts 11 arranged in a rectangular array are slidably connected inside the second connecting frame 10.
[0032] Example 2: Please refer to Figure 2 , Figure 4 and Figure 5A spark detector 13 is fixedly connected to the upper end of the cotton inlet pipe 9. A control box 14 is fixedly connected to one side of the cotton inlet pipe 9. A connecting wire 15 is fixedly connected to one side of the upper end of the control box 14. An alarm light 16 is fixedly connected to the upper end of the control box 14 away from the connecting wire 15. By installing a spark detector 13 at the upper end of the cotton inlet pipe 9 and equipping a control box 14 on one side of the cotton inlet pipe 9, and connecting the spark detector 13 and the control box 14 with the connecting wire 15, and installing an alarm light 16 on the control box 14, the spark detector 13 can monitor in real time whether sparks are generated during the cotton conveying process inside the cotton inlet pipe 9. Once a spark is detected, it will transmit a signal to the control box 14 through the connecting wire 15. After receiving the signal, the control box 14 will trigger... The alarm light 16 is activated to promptly warn staff of potential fire hazards, allowing them to quickly detect and address such hazards and prevent accidents caused by sparks. This ensures the safe operation of the cotton inlet pipe 9 of the multi-compartment machine. Multiple observation windows 17 arranged in a linear array are fixedly connected to one side of the cotton distribution pipe 1. These windows allow staff to directly observe the flow of cotton inside the distribution pipe 1 without disassembling the pipe or stopping the machine. Any abnormalities detected can be quickly identified, and targeted measures can be taken. Two gaskets 5 and an L-shaped baffle 7 are installed between the connecting pipe 2 and the cotton inlet pipe 9. During assembly, the gasket 5 fills the gap between the connecting pipe 2 and the cotton inlet pipe 9, reducing airflow leakage caused by loose connections and preventing airflow leakage from affecting the stability of cotton flow. Simultaneously, the L-shaped baffle 7 fixes one side of the short side between the connecting pipe 2 and the cotton inlet pipe 9, guiding the cotton flow when it enters the right-angle transition area, reducing potential cotton flow turbulence at the right-angle transition, and preventing cotton fibers from accumulating and clogging the joint. Multiple connecting bolts 11 are threaded through one end of the first through hole 4 and connected to a nut 12. Multiple connecting bolts 11 are also installed inside the second through hole 6 and the third through hole 8. By allowing multiple connecting bolts 11 to pass sequentially through the second through hole 6 of the gasket 5 and the third through hole 8 of the baffle 7, and passing through the first connecting frame 3... A threaded nut 12 is connected to a through hole 4, allowing the connecting pipe 2 and the cotton inlet pipe 9 to be tightly fixed through the first connecting frame 3 and the second connecting frame 10. Simultaneously, the baffle 7 and gasket 5 are securely clamped between the connecting pipe 2 and the cotton inlet pipe 9, ensuring that they do not shift or loosen during cotton flow impact and equipment operation vibration. Furthermore, when maintenance is required, the components can be quickly separated by removing the bolts, facilitating inspection or replacement of the baffle 7, gasket 5, etc. One end of each of the two L-shaped baffles 7 passes through the interior of the connecting pipe 2 and extends into the cotton distribution pipe 1. By having one end of each L-shaped baffle 7 pass through the connecting pipe 2 and extend into the cotton distribution pipe 1, the L-shaped baffles 7 function in the transition area where the cotton flow is about to enter the cotton distribution pipe 1 after entering the connecting pipe 2 from the cotton inlet pipe 9.The portion extending into the cotton distribution pipe 1 can directly guide the cotton flow entering this area, preventing cotton from concentrating on one side of the distribution pipe 1, reducing congestion within the distribution pipe 1, and ensuring smooth cotton delivery. The end of the connecting wire 15 furthest from the control box 14 is fixedly connected to the spark detector 13, and the spark detector 13 and the control box 14 are electrically connected. By fixing the end of the connecting wire 15 furthest from the control box 14 to the spark detector 13, the spark detector 13 and the control box 14 are electrically connected. When the spark detector 13 detects a spark in the cotton inlet pipe 9, it can quickly transmit the signal to the control box 14 through the connecting wire 15, allowing the control box 14 to receive and process it promptly. This signal triggers alarm light 16 to issue a warning, ensuring that staff can quickly identify potential safety hazards within the pipeline and prevent accidents caused by sparks. The detection end of spark detector 13 penetrates the upper end of the cotton inlet pipe 9, allowing it to directly contact the cotton conveying environment inside. When sparks are generated due to friction or other reasons during cotton flow within the pipe, the detection end can directly capture the spark signal, ensuring that spark detector 13 can quickly and accurately detect potential safety hazards within the pipeline. This provides timely and reliable information for the control box 14 to trigger an alarm, further enhancing the operational safety of the cotton inlet pipe 9.
[0033] The working principle of the above embodiments is as follows:
[0034] During installation, multiple connecting bolts 11 are sequentially passed through the second through hole 6 of the gasket 5 and the third through hole 8 of the baffle 7, and a threaded nut 12 is threaded through the first through hole 4 of the first connecting frame 3. This allows the connecting pipe 2 and the cotton inlet pipe 9 to be tightly fixed through the first connecting frame 3 and the second connecting frame 10. Simultaneously, the baffle 7 and gasket 5 are securely clamped between the connecting pipe 2 and the cotton inlet pipe 9, ensuring that they will not shift or loosen during cotton flow impact and equipment operation vibration. During the cotton feeding process of the multi-compartment machine, cotton enters the connecting pipe 2 from the cotton inlet pipe 9, and is then transported to the cotton distribution pipe 1 through the connecting pipe 2. One end of the L-shaped baffle 7 on both sides of the connecting pipe 2 extends into the cotton distribution pipe 1, converging and guiding the cotton flow when it passes through the right-angle transition area, preventing cotton from... Due to inertia, the cotton flow is concentrated on one side of the cotton distribution pipe 1, causing congestion. This allows the cotton to enter the cotton distribution pipe 1 more evenly. The spark detector 13 at the upper end of the cotton inlet pipe 9 extends directly into the pipe to monitor the sparks that may be generated during the cotton conveying process in real time. Once a spark is detected, the signal is transmitted to the control box 14 on one side through the connecting wire 15. After receiving the signal, the control box 14 immediately triggers the alarm light 16 to issue a warning, reminding the staff to deal with the safety hazard in time. At the same time, multiple observation windows 17 on one side of the cotton distribution pipe 1 allow the staff to observe the internal cotton flow status at any time without stopping the machine, making it easier to detect and resolve abnormalities in a timely manner. The device, through the setting of two L-shaped baffles, achieves smooth cotton conveying, reduces congestion, and ensures the stable operation of the cotton inlet system of the multi-bin machine.
