Description

Technical Field

[0001] This invention relates to the field of duct manufacturing technology, specifically to a self-rotating fiberglass duct outer circle grinding device. Background Technology

[0002] Fiberglass ducts are becoming increasingly widely used, but during the duct production process, the outer circumference of the duct needs to be ground to remove surface burrs and trim the shape. Currently, the most common grinding methods involve manual hand-held grinding tools or localized grinding using simple grinding equipment. However, manual grinding is not only labor-intensive, but the grinding quality is also greatly affected by human factors, making it difficult to ensure uniform grinding. Most existing equipment can only process ducts of a fixed diameter. For ducts of different diameters, it is necessary to replace parts or even replace the equipment, which is not convenient to use. In addition, the grinding process generates a lot of dust, which not only affects the working environment but may also have adverse effects on the health of operators. Summary of the Invention

[0003] The purpose of this invention is to address the deficiencies and shortcomings of existing technologies by providing a rationally designed self-rotating fiberglass duct outer circle grinding device, which can solve the aforementioned deficiencies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a body, on which a pipe feeding mechanism for conveying pipes is installed, and a grinding mechanism for grinding air ducts is installed on the body via an angle adjustment mechanism, and a dust suction mechanism connected to the grinding mechanism is provided inside the body.

[0005] Preferably, the grinding mechanism includes multiple grinding wheels, two support frames are provided on the machine body, a rotating frame is rotatably connected between the two support frames, the grinding wheels are all located at the front end of the rotating frame, and a drive motor is also provided on the machine body, the shaft of the drive motor is drivenly connected to the grinding wheels.

[0006] Preferably, both ends of the rotating frame are rotatably connected to the support frame via annular support bearings. A rotating shaft is rotatably mounted on the two support frames via a bearing. The rotating shaft passes through the support bearing and the two are concentrically mounted. The front end of the drive motor shaft is connected to a rotating shaft, which is driven to the rotating shaft, and the rotating shaft is driven to the rotating shaft of the grinding wheel.

[0007] Preferably, the angle adjustment mechanism includes multiple tension springs located at the bottom of the rotating frame, which are connected between the bottom surface of the rotating frame and the platform of the machine body. A height adjustment mechanism is also provided on the platform, comprising a guide seat mounted on the platform, with two lifting screws on its inner side. A lifting cover is slidably mounted on the guide seat, and a lifting block is connected downwards inside the lifting cover. Blind holes are opened in the lifting blocks, and nuts are respectively installed in the blind holes. The lifting screws are threaded into the nuts. A support block is rotatably connected to the top of the lifting cover via a movable shaft, and the top surface of the support block is in contact with the rotating frame. A transmission box is located below the platform, and a lifting motor is located on its side. The shaft of the lifting motor is connected to the two lifting screws via the transmission box.

[0008] Preferably, the rotating frame is provided with multiple dust covers, all of which are located above the grinding wheel. The dust collection mechanism includes a dust collection fan located inside the machine body and a filter box connected thereto. The filter box is also connected to a main air duct for sucking in impurity gases. Each dust cover has an air intake connected to both ends. Each air intake is connected to an air duct 2 through an air duct 1. The air duct 2 is connected to an air duct 3 through a flexible air duct. On the table, multiple bottom dust collection grooves are provided below the grinding wheel. The bottom dust collection grooves and the air duct 3 are all connected to the main air duct.

[0009] Preferably, a partition is provided at the top of the filter box to form a U-shaped air duct, and multiple W-shaped filter plates are provided on both sides of the partition. The main air duct and the outlet air duct are respectively connected to the two ends of the air duct. An isolation mesh plate is provided inside the filter box, with the top surface of the isolation mesh plate attached to the bottom surface of the partition. A filling cavity is formed below the isolation mesh plate, which is filled with filter material.

[0010] Preferably, the feeding mechanism includes a feeding roller shaft rotatably mounted on the machine body, with threaded grooves on its surface, and a number of driven wheels arranged in a straight line on the machine body; a reducer is provided on the machine body, and the rotating shaft passes through two support frames and is connected to the input end of the reducer via a transmission belt, while its output end is connected to the feeding roller shaft via a transmission belt.

[0011] Preferably, the bottom of the machine body is provided with multiple support feet.

[0012] The beneficial effects of the present invention after adopting the above structure are: This invention sets up a feeding mechanism and a grinding mechanism, with a drive motor simultaneously driving the grinding wheel to rotate and the feeding roller shaft to rotate. A single motor can complete both feeding and grinding, saving costs and improving utilization.

[0013] This invention, by setting an angle adjustment mechanism, makes the angle of the rotating frame adjustable, thereby changing the processing space size formed between the grinding wheel, the feeding roller shaft, and the driven wheel, so that the device can adapt to the processing needs of air ducts of different diameters and has good equipment versatility.

[0014] This invention provides a dust cover above the grinding wheel and a dust-collecting structure on both sides and bottom of the grinding area. This allows the dust generated during grinding to be sucked in from multiple angles in a timely manner, even if it splashes. At the same time, the dust is filtered through the filter plate and filter media in the filling chamber, thereby reducing dust overflow and improving the working environment.

[0015] This invention enables the rotating frame to be stably supported and its height adjusted by setting a tension spring and a lifting adjustment structure. The structure is simple and reliable. Not only can it be used for height adjustment, but the spring can also be stretched. When the force on the air duct is too great, the rotating frame can also be raised, which improves the overall operational stability of the equipment. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] See Figures 1-10 As shown, it includes a body 1, with multiple support feet 2 at the bottom of the body 1. The body 1 is equipped with a pipe feeding mechanism for conveying pipes and a grinding mechanism for grinding air ducts. The grinding mechanism is mounted on the body 1 via an angle adjustment mechanism. A protective cover 7 is provided outside the grinding mechanism to reduce dust from flying out. A dust collection mechanism connected to the grinding mechanism is provided inside the body 1. The grinding mechanism includes multiple grinding wheels 19. The machine body 1 is provided with two support frames 9, and a rotating frame 12 is rotatably connected between the two support frames 9. The grinding wheels 19 are all located at the front end of the rotating frame 12. The machine body 1 is also provided with a drive motor 8, and the rotating shaft of the drive motor 8 is connected to the grinding wheels 19. The two ends of the rotating frame 12 are rotatably connected to the support frame 9 via annular support bearings 15. A rotating shaft 10 is rotatably mounted on each of the two support frames 9 via a bearing 14. The rotating shaft 10 passes through the support bearings 15 and is concentrically mounted. A rotating shaft 11 is connected to the front end of the drive motor 8's shaft. The rotating shaft 11 is driven to the rotating shaft 10, which is then driven to the shaft of the grinding wheel 19. Specifically, the rotating frame 12 contains a grinding transmission shaft 17, which is connected to the rotating shaft 10 via a transmission belt assembly 16. The grinding transmission shaft 17 is connected to the shaft of the grinding wheel 19 via a transmission gear assembly 18. The grinding speed is adjusted by the gear ratio of this gear assembly to adapt to the motor speed and the required grinding speed. A shaft protection cover 21 is provided on the outer side of one of the support frames 9 away from the drive motor 8, located outside the rotating shaft 10. The angle adjustment mechanism includes multiple tension springs 22 located at the bottom of the rotating frame 12, which are connected between the bottom surface of the rotating frame 12 and the platform of the machine body 1. A height adjustment mechanism is also provided on the platform, including a guide seat 26 mounted on the platform. Two lifting screws 28 are located inside the guide seat 26. A lifting cover 23 slides on the guide seat 26. A lifting block 27 is connected downwards inside the lifting cover 23. Blind holes are formed in the lifting block 27, and nuts 29 are respectively installed in the blind holes. The lifting screws 28 are threaded into the nuts 29. The top of the lifting cover 23 is movably rotated... A support block 24 is rotatably connected to shaft 25, and the top surface of support block 24 is in contact with rotating frame 12; a transmission box 30 is provided below the platform, and a lifting motor 32 is provided on its side. The lifting motor 32 is a servo motor that can precisely control the lifting height; two connecting rods 31 are rotatably installed inside the transmission box 30. The top ends of the connecting rods 31 are connected to the lifting screw 28 through couplings, and the two connecting rods 31 are connected by transmission gear 34. The two rotate in the same direction and at the same speed. After the shaft of the lifting motor 32 extends into the transmission box 30, it is connected to one of its connecting rods 31 through bevel gear set 33. The pipe feeding mechanism includes a feeding roller shaft 5 rotatably mounted on the machine body 1, with threaded grooves on its surface. The machine body 1 is also provided with several driven wheels 6 arranged in a straight line. The machine body 1 is provided with a reducer 13. The rotating shaft 11 passes through two support frames 9 and is connected to the input end of the reducer 13 via a transmission belt. Its output end is connected to the feeding roller shaft 5 via a transmission belt. The machine body 1 is provided with V-shaped inlet pipe grooves 3 and outlet pipe grooves 4 on both sides to facilitate temporary storage of pipes during entry and exit and prevent them from falling.

[0020] The drive motor 8 serves as the power source for grinding and feeding. On one hand, it drives the feeding roller shaft 5 to rotate through the rotating shaft 2 11 and the reducer 13, pushing the air duct inward in a spiral manner until it is finished and sent out. On the other hand, it drives the grinding wheel 19 to rotate through the rotating shaft 10, the transmission belt group 16 and the transmission gear group 18. Both paths are equipped with speed regulation. By changing the gear reduction ratio or the reduction ratio of the reducer 13, motors with different speeds can be used, or the feeding or grinding speed can be changed separately. This saves production costs and allows for the selection of appropriate speeds according to needs, making the equipment highly flexible. The angle of the rotating frame 12 determines the height of the front grinding wheel 19. The heights of the lower feeding roller shaft 5 and driven wheel 6 are fixed. Therefore, adjusting the angle of the rotating frame 12 changes the diameter of the round pipe that can be accommodated between the grinding wheel 19, the lower feeding roller shaft 5, and the driven wheel 6, thus adapting to the processing of air ducts of different diameters. Specifically, the tension spring 22 and the gravity of the rotating frame 12 will cause it to press down, and it is rotatably connected to the support frame 9. At this time, the support block 24 limits the rotation of the rotating frame 12. The lifting motor 32 drives the two lead screws to rotate through the gear set, which in turn drives the lifting cover 23 to rise and fall through the thread, thereby changing the height of the support block 24. The support block 24 is rotatably connected, so when the angle of the rotating frame 12 changes, the support block 24 will also rotate adaptively. During this process, friction will also occur between the surface of the support block 24 and the rotating frame 12. Therefore, the surface of the support block 24 and the bottom surface of the rotating frame 12 can be coated with Teflon or molybdenum disulfide to reduce wear caused by surface friction.

[0021] See Figures 1-11 As shown, the rotating frame 12 is equipped with multiple dust covers 20, all of which are located above the grinding wheel 19. The dust collection mechanism includes a dust collection fan 43 located inside the machine body 1 and a filter box 42 connected thereto. The filter box 42 is also connected to a main air duct 40 for sucking in impurity gases. Each dust cover 20 has a suction port 35 connected to both ends. The suction port 35 is connected to a second air duct 37 through an air duct 1 36. The second air duct 37 is connected to a third air duct 39 through a flexible air duct 38. On the table, multiple bottom dust collection grooves 41 are provided below the grinding wheel 19. The bottom dust collection grooves 41 and the third air duct 39 are all connected to the main air duct 40. A partition is provided at the top of the filter box 42 to form a U-shaped air duct. Multiple W-shaped filter plates 45 are provided on both sides of the partition. The main air duct 40 and the outlet air duct 44 are respectively connected to the two ends of the air duct. An isolation mesh plate 46 is provided inside the filter box 42. The top surface of the isolation mesh plate 46 is attached to the bottom surface of the partition. A filling cavity 47 is formed below the isolation mesh plate 46, which is filled with filter media. The filter media is activated carbon. A removable door is provided at the front of the filter box 42 to facilitate the replacement of filter media or the cleaning of filter plates 45.

[0022] By suctioning from multiple points, airflow can be generated simultaneously on both sides of the grinding wheel 19 and below the grinding position, allowing the dust generated during grinding to enter with the airflow and then be filtered out by the filter plate 45 and activated carbon. The airflow is discharged by the fan, and the flexible air duct 38 can maintain airflow continuity as the angle of the rotating frame 12 changes.

[0023] The installation, connection, or setting methods of the components not detailed above are all common mechanical methods, and the specific structure, model, and coefficient indicators of all their components are their own technologies, such as gear reduction ratios and motor control methods. As long as they can achieve their beneficial effects, they can be implemented, so they will not be elaborated further.

[0024] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention.
