Description

Technical Field

[0001] This application relates to the technical field of fine cotton opening machines, and in particular to an anti-blocking device for the discharge port of a fine cotton opening machine. Background Technology

[0002] The cotton opening machine is mainly used for processing raw cotton of various grades or chemical fibers with a length of less than 76 mm. It is used as the last step in the cotton opening process. The raw cotton is sucked into the cotton feeding channel by the cotton condenser. The beaters open and comb the cotton, further opening up small pieces of raw material. The dust removal knife and dust cage remove impurities and short fibers. Then, the cotton is sucked into the next process by airflow.

[0003] However, most existing fine cotton opening machines do not have a detection device to check for blockages in the discharge pipe. When a blockage occurs, it cannot be detected in time, which can prevent the material from being discharged normally and may damage the equipment. Utility Model Content

[0004] The purpose of this application is to provide an anti-blocking device for the discharge port of a fine cotton opener, which has the advantages of facilitating real-time monitoring of the discharge pipe. This solves the problem that most existing fine cotton openers do not have a detection device for whether the discharge pipe is blocked. When the discharge pipe is blocked, it cannot be detected in time, which leads to the inability of material to be discharged normally and may cause damage to the equipment.

[0005] The present application provides a device for preventing blockage at the outlet of a fine cotton opener, which adopts the following technical solution: A device for preventing blockage at the outlet of a fine cotton opener includes a fine cotton opener body. Four threaded columns arranged in a rectangular array are fixedly connected to one side of the upper end of the fine cotton opener body. Two shim nuts arranged in a linear array are threadedly connected to the outer walls of the four threaded columns. An installation plate is slidably connected to the outer walls of the four threaded columns. A vertical plate is fixedly connected to the upper end of the installation plate. A support plate is fixedly connected to the upper end of the vertical plate. A photoelectric material level detection switch is fixedly connected to the upper end of the support plate. A fixing nut is threadedly connected to one end of each of the four threaded columns that passes through the installation plate. A discharge square tube is fixedly connected to one side of the upper end of the fine cotton opener body. Two transparent windows arranged in a linear array are fixedly connected inside the discharge square tube.

[0006] By adopting the above technical solution, a photoelectric level detection switch supported by a mounting plate, upright plate, and support plate is installed on one side of the upper part of the fine cotton opening machine body. This photoelectric level detection switch can detect whether there is a blockage inside the discharge square tube. By installing threaded posts, shims, and fixing nuts on the fine cotton opening machine body, the height of the mounting plate can be flexibly adjusted, thereby adjusting the position of the photoelectric level detection switch on the upright plate and support plate to correspond with the transparent window of the discharge square tube. This avoids the photoelectric level detection switch's illumination surface being too far from the transparent window, which could lead to insensitive alarms. When a blockage occurs inside the discharge square tube, causing material to accumulate to the point of obstructing the transparent window, the photoelectric level detection switch can promptly detect and send a signal, achieving real-time monitoring of whether there is a blockage inside the discharge tube. This allows for timely detection of blockages and prevents equipment damage due to material not being able to discharge normally.

[0007] Preferably, an audible and visual alarm is fixedly connected to one side of the upper end of the cotton opening machine body.

[0008] By adopting the above technical solution, an audible and visual alarm is installed on one side of the upper part of the fine cotton opening machine. When the photoelectric material level detection switch detects a blockage inside the discharge square tube, it will transmit a signal to the audible and visual alarm, causing it to emit sound and light warnings, which can attract the attention of the operator and ensure that the blockage is detected and dealt with in a timely manner.

[0009] Preferably, an inspection port is provided on one side of the discharge square tube, a sealing cover is rotatably connected to one side of the inspection port, and a handle is fixedly connected to one side of the sealing cover.

[0010] By adopting the above technical solution, an inspection port is opened on one side of the discharge square tube, and a sealing cover with a handle is rotated and connected at the inspection port. When a blockage is detected and needs to be cleared, the operator can easily open the sealing cover through the handle and directly clear the blockage material inside the discharge square tube from the inspection port without disassembling the entire discharge tube. After the cleaning is completed, the sealing cover is closed to restore normal operation. This simplifies the blockage handling process, quickly restores equipment operation, and reduces production downtime caused by clearing blockages.

[0011] Preferably, a sealing ring is fixedly connected to the end of the sealing cap away from the handle.

[0012] By adopting the above technical solution, a sealing ring is set at the end of the sealing cover away from the handle. When the sealing cover is closed, the sealing ring will fit tightly against the edge of the inspection port, thereby enhancing the sealing performance between the sealing cover and the discharge square tube. This prevents the airflow in the discharge square tube from carrying material and leaking out from the gap between the inspection port and the sealing cover during normal operation of the equipment, ensuring that the material can be transported normally.

[0013] Preferably, an upper cotton box is fixedly connected to the upper end of the cotton opening machine body, and observation windows are fixedly provided on both sides of the upper cotton box.

[0014] By adopting the above technical solution, by setting an upper cotton box at the top of the fine cotton opener and fixing observation windows on both sides of the upper cotton box, the operator can check the raw material storage and flow status inside the upper cotton box at any time through the observation windows, ensuring that the opening and impurity removal processes of the fine cotton opener can be carried out stably, and avoiding the impact of abnormal raw material status in the upper cotton box on the overall production process.

[0015] Preferably, a cotton condenser is fixedly connected to the upper end of the cotton box, and a dust discharge pipe is fixedly connected to one side of the cotton condenser.

[0016] By adopting the above technical solution, the cotton condenser can adsorb and transport external raw cotton and other materials into the upper cotton box. At the same time, during the adsorption and transportation process, dust and fine impurities mixed in the raw materials are separated out. These impurities are discharged to the outside of the equipment through the dust exhaust pipe, ensuring the purity of the raw materials entering the upper cotton box.

[0017] Preferably, the photoelectric level detection switch is electrically connected to the audible and visual alarm.

[0018] By adopting the above technical solution, and electrically connecting the photoelectric level detection switch with the audible and visual alarm, when the photoelectric level detection switch detects a blockage inside the discharge square tube, it will immediately transmit a signal to the audible and visual alarm, enabling the audible and visual alarm to respond quickly and issue a warning. This achieves automatic linkage between blockage detection and alarm, completing the process from detection to warning without manual intervention, ensuring that operators can know about the blockage situation and handle it in a timely manner.

[0019] Preferably, the photoelectric level detection switch corresponds to the transparent viewing window.

[0020] By adopting the above technical solution, the light emitted by the photoelectric material level detection switch can detect the material status inside the discharge square tube through the transparent window. When the material inside the tube accumulates to the point of blocking the transparent window, the detection switch can directly sense the change in light, thereby accurately judging the blockage.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] This anti-clogging device for the discharge port of a fine cotton opener uses threaded posts, shims, and fixing nuts on the machine body to install a mounting plate with a vertical plate and a support plate. A photoelectric level detection switch on the support plate corresponds to the transparent window of the discharge square tube, enabling real-time monitoring of blockages inside the tube. When material accumulates and obstructs the transparent window, the photoelectric level detection switch sends a signal. Electrical connection to an audible and visual alarm allows the alarm to promptly issue sound and light warnings, alerting the operator. Simultaneously, the inspection port on the discharge square tube, equipped with a sealing cover and handle, facilitates quick cleaning of blocked materials. The sealing ring on the cover ensures the equipment's airtightness during operation, preventing material and airflow leakage. The observation windows on the upper cotton box and both sides allow for easy monitoring of the raw material status. Combined with the condenser and dust exhaust pipe for purified raw material transport, this device reduces the risk of blockages, preventing equipment damage and production interruptions due to undetected blockages in the discharge pipe, thus improving equipment stability and production efficiency.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0031] Example 1: A device for preventing blockage at the outlet of a fine cotton opening machine. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3The machine includes a fine cotton opener body 1. Four threaded posts 2 arranged in a rectangular array are fixedly connected to one side of the upper end of the fine cotton opener body 1. Two shim nuts 3 arranged in a linear array are threaded to the outer walls of each of the four threaded posts 2. A mounting plate 4 is slidably connected to the outer walls of the four threaded posts 2. The height of the mounting plate 4 can be flexibly adjusted by setting the threaded posts 2, shim nuts 3, and fixing nuts 8 on the fine cotton opener body 1. A vertical plate 5 is fixedly connected to the upper end of the mounting plate 4. A support plate 6 is fixedly connected to the upper end of the vertical plate 5. A photoelectric material level detection switch 7 is fixedly connected to the upper end of the support plate 6. By setting the photoelectric material level detection switch 7, supported by the mounting plate 4, vertical plate 5, and support plate 6, on one side of the upper end of the fine cotton opener body 1, the photoelectric material level detection switch 7 can detect whether there is a blockage inside the discharge square tube 9. The four threaded posts... One end of column 2, which passes through mounting plate 4, is threaded with a fixing nut 8. A discharge square tube 9 is fixedly connected to one side of the upper end of the fine cotton opening machine body 1. Inside the discharge square tube 9, two transparent windows 10 arranged in a linear array are fixedly connected. The position of photoelectric material level detection switches 7 on the upright plate 5 and support plate 6 is adjusted so that they correspond to the transparent windows 10 of the discharge square tube 9. This avoids the photoelectric material level detection switch 7 being too far from the transparent windows 10, which would cause the alarm to be insensitive. When the discharge square tube 9 is blocked and the material accumulates to the position that blocks the transparent windows 10, the photoelectric material level detection switch 7 can detect it in time and send a signal, realizing real-time monitoring of whether the discharge tube is blocked. This allows the blockage to be detected in time, avoiding equipment damage caused by the inability of material to be discharged normally.

[0032] Example 2: Please refer to Figure 1 , Figure 4 and Figure 5A device for preventing blockage at the discharge port of a fine cotton opener is disclosed. An audible and visual alarm 11 is fixedly connected to one side of the upper end of the fine cotton opener body 1. When a photoelectric material level detection switch 7 detects a blockage inside the discharge square tube 9, it transmits a signal to the alarm 11, causing it to emit sound and light warnings. This attracts the operator's attention, ensuring the blockage is detected and addressed promptly. An inspection port 12 is provided on one side of the discharge square tube 9. A sealing cover 13 is rotatably connected to one side of the inspection port 12. A handle 14 is fixedly connected to one side of the sealing cover 13. By providing an inspection port 12 and a sealing cover 13 with a handle 14, the operator can easily access the device by using the handle 14 when a blockage is detected and cleaning is required. Open the sealing cover 13 directly to clean the blockage inside the discharge square tube 9 through the inspection port 12. There is no need to disassemble the entire discharge tube. After cleaning, close the sealing cover 13 to restore normal operation. This simplifies the blockage handling process and allows for quick equipment recovery, reducing production downtime caused by blockage cleaning. A sealing ring 15 is fixedly connected to the end of the sealing cover 13 away from the handle 14. By setting the sealing ring 15 at the end of the sealing cover 13 away from the handle 14, when the sealing cover 13 is closed, the sealing ring 15 will fit tightly against the edge of the inspection port 12, thereby enhancing the sealing between the sealing cover 13 and the discharge square tube 9. This prevents the airflow inside the discharge square tube 9 from carrying material through the gap between the inspection port 12 and the sealing cover 13 during normal equipment operation, ensuring that the material can be transported normally.

[0033] Please see Figure 1 , Figure 3 and Figure 4The upper part of the cotton opening machine body 1 is fixedly connected to the upper cotton box 16. Observation windows 17 are fixedly installed on both sides of the upper cotton box 16. By setting the upper cotton box 16 at the upper part of the cotton opening machine body 1 and fixing the observation windows 17 on both sides of the upper cotton box 16, the operator can check the raw material storage and flow status inside the upper cotton box 16 at any time through the observation windows 17. This ensures that the opening and impurity removal processes of the cotton opening machine can be carried out stably and avoids the overall production process from being affected by abnormal raw material status inside the upper cotton box 16. The upper cotton box 16 is fixedly connected to the upper end of the cotton box 16. A dust discharge pipe 19 is fixedly connected to one side of the cotton box 18. The cotton box 18 can adsorb and transport external raw materials such as raw cotton into the upper cotton box 16. At the same time, during the adsorption and transportation process, dust and fine impurities mixed in the raw materials are separated. These impurities are discharged outside the equipment through the dust discharge pipe 19, ensuring that the raw materials entering the upper cotton box 16 are clean and safe. The purity of the raw materials is ensured by the photoelectric level detection switch 7, which is electrically connected to the audible and visual alarm 11. By electrically connecting the photoelectric level detection switch 7 and the audible and visual alarm 11, when the photoelectric level detection switch 7 detects a blockage inside the discharge square tube 9, it will immediately transmit a signal to the audible and visual alarm 11, causing the audible and visual alarm 11 to respond quickly and issue a warning. This achieves automatic linkage between blockage detection and alarm, completing the process from detection to warning without manual intervention. This ensures that operators can know about the blockage situation and deal with it in a timely manner. The photoelectric level detection switch 7 corresponds to the transparent window 10. The light emitted by the photoelectric level detection switch 7 can detect the material status inside the discharge square tube 9 through the transparent window 10. When the material in the tube accumulates to the point of blocking the transparent window 10, the detection switch can directly sense the change in light, thereby accurately judging the blockage situation.

[0034] The implementation principle of this application embodiment is as follows:

[0035] During operation, the cotton condenser 18 adsorbs and transports external raw cotton and other materials to the upper cotton box 16. Simultaneously, dust and fine impurities mixed in the raw materials are discharged through the dust exhaust pipe 19, ensuring the purity of the raw materials entering the upper cotton box 16. Operators can monitor the storage volume and flow status of the internal raw materials at any time through the observation windows 17 on both sides of the upper cotton box 16. After the raw materials undergo opening and impurity removal by the fine cotton opener body 1, they enter the discharge square pipe 9 and are transported to the next process. During this process, the photoelectric material level detection switch 7 installed on the threaded column 2 corresponds to the transparent window 10 on the discharge square pipe 9, allowing real-time monitoring of the material status inside the pipe. Furthermore, the shim nut 3 and fixing nut 8 on the threaded column 2 can flexibly adjust the height of the mounting plate 4 to ensure the photoelectric material level detection switch... The relative positions of switch 7 and transparent window 10 are precise, avoiding the impact of distance deviation on detection sensitivity. When a blockage occurs inside the discharge square tube 9, causing material to accumulate and obstruct the transparent window 10, the photoelectric level detection switch 7 will immediately sense the change in light and send a signal. The signal will be quickly transmitted to the audible and visual alarm 11, which will simultaneously emit sound and light warnings to promptly remind the operator to handle the blockage. After receiving the warning, the operator can open the sealing cover 13 at the inspection port 12 through handle 14 and directly clean the blockage material inside the tube through the inspection port 12. After cleaning, the sealing cover 13 is closed. At this time, the sealing ring 15 at one end of the sealing cover 13 fits tightly with the edge of the inspection port 12, ensuring the sealing of the discharge square tube 9, preventing material and air leakage, and ensuring that the equipment quickly returns to normal operation.
