Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, specifically a cleaning roller brush for the inner wall of a silk-making pipe. Background Technology

[0002] During the use of filament-making pipes, the cleanliness of the inner wall of the pipe directly affects the product quality and production efficiency. Currently, some pipe cleaning equipment based on technologies such as mechanical scraping, high-pressure water jetting, and chemical cleaning has appeared on the market. However, these devices often have problems such as complex structural design and low cleaning efficiency. In addition, these devices may cause damage to the inner wall of the pipe during operation or require additional auxiliary devices.

[0003] For example, the Chinese utility model patent (application number: 202120567845.2) discloses a "pipe inner wall cleaning device," which includes a drive motor, a transmission shaft, and a cleaning brush head mounted on the transmission shaft. The cleaning brush head is fixed to the transmission shaft via a threaded connection. The drive motor is connected to the transmission shaft via a coupling. A protective sleeve is provided outside the transmission shaft, and the protective sleeve has an inlet and an outlet. A flexible scraper is provided on the outer side of the cleaning brush head. This application can achieve basic cleaning of the inner wall of the pipe, but its structural design is poorly adaptable to pipes of different diameters, and the replacement of the cleaning brush head is cumbersome. The aforementioned patent can corroborate the limitations of the prior art.

[0004] Therefore, we have made improvements to this by proposing a cleaning roller brush for the inner wall of the silk-making pipe. Utility Model Content

[0005] The purpose of this invention is to solve the problems of complex structure, low cleaning efficiency and poor adaptability to pipes of different diameters in existing wire-making pipe cleaning devices, while avoiding damage to the inner wall of the pipe during the cleaning process.

[0006] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a cleaning roller brush for the inner wall of a filament-making pipe, comprising a drive module, a transmission module, and a cleaning module. The drive module is connected to the cleaning module via the transmission module. The cleaning module includes multiple cleaning units, each with a flexible cleaning strip on its outer side. The surface of the flexible cleaning strip is covered with microporous structures for adsorbing dirt particles. The cleaning module also includes an elastic adjustment component, which allows the cleaning units to adaptively expand and contract radially to match the inner walls of pipes with different diameters.

[0007] The drive module includes a motor and a reducer. The output shaft of the motor is connected to the input end of the reducer via a coupling, and the output end of the reducer is fixedly connected to the transmission module via a keyway. The transmission module includes a main shaft and multiple support rings sleeved on the main shaft. The support rings are evenly distributed along the axial direction of the main shaft, and each support ring has a groove on its outer side for mounting a cleaning unit.

[0008] As a preferred technical solution of this application, the cleaning unit includes a fixed seat and a movable seat. The fixed seat is fixedly connected to the support ring by bolts. The movable seat is embedded in the interior of the fixed seat by a sliding fit. The outer side of the movable seat is provided with a guide protrusion. The guide protrusion cooperates with the guide groove inside the fixed seat to realize the linear movement of the movable seat in the radial direction.

[0009] As a preferred technical solution of this application, the elastic adjustment component includes a spring and a limiting block. One end of the spring contacts the bottom end of the movable seat, and the other end contacts the bottom of the fixed seat. The limiting block is fixed inside the fixed seat to limit the maximum extension distance of the movable seat. When the cleaning roller brush enters the pipe, the movable seat is subjected to pressure from the inner wall of the pipe, and the cleaning unit achieves adaptive adjustment through the compression or extension of the spring.

[0010] As a preferred technical solution of this application, the flexible cleaning strip is connected to the movable seat through a snap-fit ​​structure. The snap-fit ​​structure includes a slot and a block. The slot is located on the outside of the movable seat, and the block is fixed on the inside of the flexible cleaning strip. The flexible cleaning strip can be quickly disassembled and replaced through the cooperation of the block and the slot.

[0011] As a preferred technical solution of this application, the main shaft is provided with bearing seats at both ends, which are fixed to the outside of the pipe by bolts. A sealing ring is provided inside the bearing seat to prevent external impurities from entering. A through hole is provided in the middle of the main shaft, extending axially along the main shaft, for conveying cleaning fluid to the cleaning module.

[0012] As a preferred technical solution of this application, a diversion pipe is provided on the outer side of the support ring. One end of the diversion pipe is connected to the through hole of the main shaft, and the other end is connected to the interior of the cleaning unit. A nozzle is provided on the outer side of the diversion pipe, and the nozzle is used to spray the cleaning liquid evenly onto the inner wall of the pipe.

[0013] As a preferred technical solution of this application, the microporous structure of the flexible cleaning strip is made of a polymer material. The polymer material has hydrophilicity and wear resistance, which can effectively adsorb dirt particles during the cleaning process and reduce wear on the inner wall of the pipe.

[0014] Compared with existing technologies, the advantages of this invention are as follows: Through the designed elastic adjustment component and cleaning unit, the cleaning roller brush achieves adaptive adjustment within pipes of different diameters. When the cleaning roller brush enters the pipe, the movable seat is subjected to pressure from the inner wall of the pipe. The radial expansion and contraction of the cleaning unit is achieved through the compression or extension of the spring, ensuring that the flexible cleaning strip always maintains close contact with the inner wall of the pipe. The microporous structure on the surface of the flexible cleaning strip effectively adsorbs dirt particles, while the hydrophilicity and abrasion resistance of its polymer material reduce damage to the inner wall of the pipe. Furthermore, through the design of the through-hole in the main shaft and the diversion pipe, the cleaning fluid can be evenly sprayed onto the inner wall of the pipe, further improving cleaning efficiency.

[0015] This utility model solves the problems of complex structure, low cleaning efficiency, and poor adaptability to pipes of different diameters in existing cleaning devices through the above technical solution. At the same time, it avoids damage to the inner wall of the pipe during the cleaning process, and has high practicality and promotion value. Attached Figure Description

[0022] This utility model provides a cleaning roller brush for the inner wall of a silk-making pipe, the specific implementation of which is as follows. Figure 1 As shown, the overall structure of the cleaning roller brush includes a drive module 1, a transmission module 2, and a cleaning module 3, wherein the drive module 1 is connected to the cleaning module 3 through the transmission module 2. The drive module 1 consists of a motor 9 and a reducer 10. The output shaft of the motor 9 is connected to the input end of the reducer 10 through a coupling, and the output end of the reducer 10 is fixedly connected to the transmission module 2 through a keyway fit. The transmission module 2 includes a main shaft 4 and multiple support rings 5 ​​sleeved on the main shaft 4. The support rings 5 ​​are evenly distributed along the axial direction of the main shaft 4, and each support ring 5 has a groove on its outer side for mounting a cleaning unit 6.

[0023] The cleaning module 3 includes multiple cleaning units 6, each consisting of a fixed base 15 and a movable base 16. The fixed base 15 is fixedly connected to the support ring 5 by bolts, and the movable base 16 is slidably fitted into the interior of the fixed base 15. A guide protrusion is provided on the outer side of the movable base 16, which engages with a guide groove inside the fixed base 15 to achieve linear movement of the movable base 16 in the radial direction. A flexible cleaning strip 7 is also provided on the outer side of the movable base 16, and the flexible cleaning strip 7 is connected to the movable base 16 via a snap-fit ​​structure. The snap-fit ​​structure includes a slot 19 and a block 20. The slot 19 is located on the outer side of the movable base 16, and the block 20 is fixed to the inner side of the flexible cleaning strip 7. The engagement of the block 20 and the slot 19 enables quick disassembly and replacement of the flexible cleaning strip 7. The surface of the flexible cleaning strip 7 is distributed with a microporous structure made of a polymer material, which is hydrophilic and abrasion-resistant, and can adsorb dirt particles during the cleaning process.

[0024] The cleaning module 3 also includes an elastic adjustment component 8, which consists of a spring 17 and a limiting block 18. One end of the spring 17 contacts the bottom end of the movable seat 16, and the other end contacts the bottom of the fixed seat 15. The limiting block 18 is fixed inside the fixed seat 15 to limit the maximum extension distance of the movable seat 16. When the cleaning roller brush enters the pipe, the movable seat 16 is subjected to pressure from the inner wall of the pipe, and the cleaning unit 6 is adaptively adjusted by the compression or extension of the spring 17. Figure 5 As shown, the working principle of the elastic adjustment component 8 is as follows: when the movable seat 16 is subjected to pressure from the inner wall of the pipe, the spring 17 is compressed and the movable seat 16 moves inward along the guide groove; when the pressure decreases, the spring 17 returns to its original state and pushes the movable seat 16 outward, thereby realizing the radial extension and retraction of the cleaning unit 6.

[0025] The main shaft 4 has bearing seats 11 at both ends, which are fixed to the outside of the pipe by bolts. Each bearing seat 11 has a sealing ring inside to prevent external impurities from entering. A through hole 12 is provided in the middle of the main shaft 4, extending axially along the main shaft 4, for conveying cleaning fluid to the cleaning module 3. Figure 4 As shown, a diversion pipe 13 is provided on the outer side of the support ring 5. One end of the diversion pipe 13 is connected to the through hole 12 of the main shaft 4, and the other end is connected to the interior of the cleaning unit 6. A nozzle 14 is provided on the outer side of the diversion pipe 13. The nozzle 14 is used to evenly spray the cleaning fluid onto the inner wall of the pipe. The cleaning fluid flows into the diversion pipe 13 from the through hole 12 of the main shaft 4, and then is sprayed onto the inner wall of the pipe through the nozzle 14, working together with the flexible cleaning strip 7 to complete the cleaning task.

[0026] In practical applications, the operator first places the cleaning roller brush into the filament-making pipe to be cleaned. After starting the motor 9, the output shaft of the motor 9 drives the reducer 10 to rotate. The output end of the reducer 10 drives the main shaft 4 to rotate through a keyway connection. The rotation of the main shaft 4 causes the support ring 5 and the cleaning unit 6 mounted on it to rotate together. When the cleaning roller brush enters the pipe, the movable seat 16 is subjected to pressure from the inner wall of the pipe. The spring 17 compresses or extends according to the pressure, thereby causing the movable seat 16 to move along the guide groove. The flexible cleaning strip 7 adjusts its position accordingly to ensure that it always maintains close contact with the inner wall of the pipe. The microporous structure on the surface of the flexible cleaning strip 7 can effectively adsorb dirt particles from the inner wall of the pipe, while the hydrophilicity and wear resistance of its polymer material reduce wear on the inner wall of the pipe. At the same time, the cleaning fluid enters the diversion pipe 13 through the through hole 12 of the main shaft 4 and is evenly sprayed onto the inner wall of the pipe through the nozzle 14, further improving the cleaning effect.

[0027] After cleaning is complete, the operator can remove the flexible cleaning strip 7 from the movable seat 16 for replacement. For example... Figure 3 As shown, the snap-fit ​​design of the flexible cleaning strip 7 makes replacement simple and quick; disassembly is completed simply by removing the clip 20 from the slot 19. Furthermore, all components of the cleaning roller brush are designed with standardization in mind, facilitating maintenance and replacement and extending the equipment's lifespan.

[0028] The above embodiments describe in detail the specific structure and operating principle of this utility model, demonstrating the connection, positional, and cooperative relationships between the various components. Through the coordinated operation of the drive module 1, transmission module 2, and cleaning module 3, the cleaning roller brush achieves adaptive adjustment within pipes of different diameters. Simultaneously, the use of cleaning fluid significantly improves cleaning efficiency, meeting practical application requirements. To better enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with specific application scenarios.

[0029] In actual operation, the cleaning roller brush is first placed into the filament-making tube to be cleaned. After starting the motor 9, the output shaft of the motor 9 drives the reducer 10 to rotate, and the reducer 10 drives the main shaft 4 to rotate through a keyway engagement. The rotation of the main shaft 4 causes the support ring 5 and the multiple cleaning units 6 mounted on its outer side to rotate together. Figure 1 As shown, the cleaning units 6 are evenly distributed within the grooves of the support ring 5, and each cleaning unit 6 includes a fixed seat 15 and a movable seat 16. The fixed seat 15 is fixedly connected to the support ring 5 by bolts, while the movable seat 16 is embedded inside the fixed seat 15 and achieves linear movement in the radial direction through the cooperation of the guide protrusion and the guide groove. When the cleaning roller brush enters the pipe, the movable seat 16 is subjected to pressure from the inner wall of the pipe. The spring 17 in the elastic adjustment assembly 8 compresses or extends according to the pressure, thereby pushing the movable seat 16 to move along the guide groove. This design ensures that the flexible cleaning strip 7 always maintains close contact with the inner wall of the pipe, while avoiding the risk of damage to the inner wall of the pipe due to excessive pressure.

[0030] The flexible cleaning strip 7 has a microporous structure on its surface, made of a polymer material that is hydrophilic and abrasion-resistant. During cleaning, when the flexible cleaning strip 7 comes into contact with the inner wall of the pipe, its microporous structure effectively adsorbs dirt particles. Figure 2 As shown, the movable seat 16 is connected to the flexible cleaning strip 7 via a snap-fit ​​structure, which includes a slot 19 and a locking block 20. When the flexible cleaning strip 7 needs to be replaced, disassembly can be completed simply by removing the locking block 20 from the slot 19. This design not only simplifies the maintenance process but also improves the overall service life of the equipment.

[0031] Meanwhile, the through hole 12 in the middle of the spindle 4 is used to deliver cleaning fluid to the cleaning module 3. For example... Figure 4 As shown, the cleaning fluid flows into the distribution pipe 13 through the through hole 12 of the main shaft 4, and is then evenly sprayed onto the inner wall of the pipe through the nozzle 14. The design of the nozzle 14 allows the cleaning fluid to cover a larger area of ​​the inner wall of the pipe, thereby working together with the flexible cleaning strip 7 to improve the cleaning effect. The introduction of the cleaning fluid not only helps to soften stubborn dirt, but also washes away dirt particles adsorbed by the flexible cleaning strip 7, thereby further improving cleaning efficiency.

[0032] The flexible adjustment component 8 plays a crucial role in ensuring that the cleaning roller brush can adaptively adjust within pipes of different diameters. For example... Figure 5As shown, the elastic adjustment assembly 8 consists of a spring 17 and a limiting block 18. One end of the spring 17 contacts the bottom end of the movable seat 16, and the other end contacts the bottom of the fixed seat 15. When the movable seat 16 is subjected to pressure from the inner wall of the pipe, the spring 17 is compressed, and the movable seat 16 moves inward along the guide groove. When the pressure decreases, the spring 17 returns to its original shape, pushing the movable seat 16 outward. The limiting block 18 limits the maximum extension distance of the movable seat 16, thereby preventing structural damage caused by excessive extension. This adaptive adjustment mechanism allows the cleaning roller brush to be used with pipes of various diameters, significantly improving the versatility and practicality of the equipment.

[0033] Furthermore, the bearing seats 11 at both ends of the main shaft 4 are fixed to the outside of the pipe with bolts, and a sealing ring is provided inside to prevent external impurities from entering the bearing seat. This design not only ensures the stable rotation of the main shaft 4, but also extends the service life of the equipment. A diversion pipe 13 is provided on the outside of the support ring 5. One end of the diversion pipe 13 is connected to the through hole 12 of the main shaft 4, and the other end is connected to the inside of the cleaning unit 6. Multiple nozzles 14 are provided on the outside of the diversion pipe 13. The positions of these nozzles 14 are precisely designed to ensure that the cleaning fluid can evenly cover the inner wall of the pipe, thereby maximizing the cleaning effect.

[0034] After cleaning is complete, the operator can quickly replace the flexible cleaning strip 7. For example... Figure 3 As shown, the flexible cleaning strip 7 is connected to the movable seat 16 via a snap-fit ​​structure. This snap-fit ​​design makes replacement simple and quick. Removal is achieved by simply removing the clip 20 from the slot 19, followed by installation of the new flexible cleaning strip 7. This design not only reduces maintenance costs but also improves the efficiency of the equipment.

[0035] Through the aforementioned steps and the coordinated operation of its components, the cleaning roller achieves efficient cleaning of the inner walls of pipes with different diameters. The microporous structure of the flexible cleaning strip 7, combined with the cleaning fluid, significantly enhances the cleaning effect, while the adaptive adjustment mechanism of the elastic adjustment component 8 ensures stable operation of the equipment under various working conditions. This invention not only solves the problems of complex structure, low cleaning efficiency, and poor adaptability to pipes of different diameters in existing cleaning devices, but also reduces damage to the inner walls of pipes through optimized design, thus possessing high practicality and promotional value.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
