[0002] A clean air duct is a device used in an air transmission system, mainly used to remove dust, bacteria, viruses and other pollutants in the air to provide a cleaner and healthier indoor air environment. A clean air duct usually consists of a filter, a fan, a muffler, etc.; it can provide cleaner and healthier indoor air, reducing the impact on human health. Secondly, a clean air duct can prevent the spread of pollutants in indoor air, reducing the risk of respiratory diseases and infections. In addition, a clean air duct can also improve the working efficiency of the air conditioning system, extend the service life of the equipment, and reduce the frequency of maintenance and cleaning.

[0003] The prior art, such as the patent with the publication number CN217914062U, discloses a material cutting device for the production and processing of clean air ducts. This technology discloses that it includes an operating table, the upper surface of the operating table is fixedly connected with a protective cover, the inner top wall of the protective cover is fixedly connected with a first electric push rod and a second electric push rod respectively, the telescopic end of the first electric push rod is fixedly connected with a sliding plate, the bottom surface of the sliding plate is fixedly connected with a limiting frame, the upper surface of the operating table is fixedly connected with a pressing frame, a threaded hole is opened on the upper surface of the pressing frame, a rotating rod is threadedly connected to the inner circle of the threaded hole, the bottom end of the rotating rod is fixedly connected with a pressing plate, a clamping block is fixedly connected to the inner side wall of the limiting frame, the bottom end of the telescopic end of the second electric push rod is fixedly connected with a cutting mechanism, a chip discharge port is opened on the upper surface of the operating table, and two supporting legs are fixedly connected to the bottom surface of the operating table, and a collection box is placed on the upper surfaces of the two supporting legs together.

DETAILED DESCRIPTION OF THE INVENTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a material cutting device for the production and processing of a clean air duct, including a support frame 1. One end of the support frame 1 is provided with a first conveying component. Two groups of limiting components are arranged on the top of the first conveying component. One end of the first conveying component away from the support frame 1 is provided with a cutting component. One end of the cutting component away from the first conveying component is provided with a second conveying component. One end of the second conveying component is provided with a measuring component. One end of the second conveying component away from the cutting component is provided with a sorting component;

[0035] The measuring component includes two groups of special-shaped blocks 2. Special-shaped telescopic rods 3 are fixedly connected to the inner cavities of the two groups of special-shaped blocks 2. Clamping rods 4 are movably connected to the inner cavities of the two groups of special-shaped blocks 2 through connecting shafts. A hydraulic rod 5 is fixedly connected between the two groups of clamping rods 4 through a movable member;

[0036] The sorting component includes a sorting table 6. A rotating shaft 7 is movably connected to the inner cavity of the sorting table 6 through a first bearing. A dialing plate 8 is fixedly connected to the outer wall of the rotating shaft 7.

[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4The tube cutting structure in the present invention is similar to the existing patent announcement number CN217914062U, which proposes a tube cutting structure; first, the tube is placed on the top of the support frame 1 and the first conveying component, and the limiting component limits the position of the tube when it squeezes the tube downward. When the first conveying component rotates, it drives the tube to move toward the end of the cutting component, so that the end of the tube is close to the cutting component, and determines whether the position of the tube is correct, and adjusts the tube. After the adjustment of the tube is completed, the cutting component is driven to rise, and the first conveying component is driven again to push the tube to the bottom of the cutting component, and the cutting component is driven again to move slowly downward to cut the tube. The second conveying component can drive the cut tube to continue to move to one side. When it moves to the side end of the measuring component, the special-shaped telescopic rod 3 can drive the special-shaped block 2 to flip 90° in a fan-shaped manner, so that the two sets of clamping rods 4 fan-shapedly move to both ends of the tube body, and drive the hydraulic rod 5, so that when the hydraulic rod 5 contracts inward, the position of the tube body is corrected by the clamping rod 4 fan-shapedly moving around the connecting shaft. When the two sets of clamping rods 4 are completely close to the tube body port, the fit between the tube body and the clamping rod 4 can be used to judge whether the cross section of the tube body is flat or not. The sorting table 6 is provided with two sets of outlets, and the sorting table 6 is inclined, and the outlet is low, so that when the tube body moves to the top of the sorting table 6, it rolls down along the angle. When the tube body is cut flawlessly, the rotating shaft 7 can drive the toggle plate 8 to fan-shapedly move to block one side of the outlet, so that the tube body rolls through the other side of the outlet, so as to continue processing; when there is a defect in the incision of the tube body, the rotating shaft 7 can drive the toggle plate 8 to fan-shapedly move to block one side of the outlet, so that the tube body rolls through the other side of the outlet, so as to return to the factory for repair, thereby improving the quality of the tube body and avoiding problems in subsequent processing.

[0038] See also Figure 1 , Figure 2 and Figure 3 The outer wall of the special-shaped telescopic rod 3 is provided with a slider 9 through a second bearing movable sleeve, and a first motor is fixedly installed at one end of the slider 9. The special-shaped telescopic rod 3 passes through the slider 9 and is fixedly connected to the output shaft of the first motor. A support rod 10 is movably inserted into the inner cavity of the slider 9, and extension rods 11 are fixedly connected at both ends of the support rod 10. The two groups of sliders 9 can be moved to both sides through the support rod 10 to the same length as the cut tube body. At the same time, the special-shaped telescopic rod 3 can be adjusted as it is expanded or contracted, thereby improving the flexibility of the device; in addition, a program can be set for the first motor so that each time the first motor is driven so that its output shaft drives the special-shaped telescopic rod 3 to rotate, the special-shaped telescopic rod 3 can only flip 90°, so that when the special-shaped telescopic rod 3 drives the clamping rod 4 to flip, the angle of the clamping rod 4 can be better controlled to avoid offset and improve the accuracy of measurement.

[0039] See also Figure 1 and Figure 4A motor 12 is fixedly installed at the bottom of the sorting platform 6 through a limit plate, and the output shaft of the motor 12 is fixedly connected to the bottom of the rotating shaft 7. Limiting protrusions 13 are fixedly arranged at both ends of the top of the sorting platform 6. The bottom of the sorting platform 6 is fixedly connected with legs. The motor 12 can be driven to drive the output shaft to drive the rotating shaft 7 to rotate. At the same time, the two sets of limiting protrusions 13 can limit the toggle plate 8. After the toggle plate 8 moves in a fan shape to a suitable position, it is limited to avoid continuous flipping, which causes the moving position of the cut tube to be offset.

[0040] See also Figure 1 and Figure 5 The first conveying assembly includes a first conveying belt 14, a first column shaft 15 is movably inserted into the inner cavity of the first conveying belt 14, a second column shaft 16 is movably inserted into the inner cavity of the first conveying belt 14 at one end away from the first column shaft 15, both ends of the first column shaft 15 and the second column shaft 16 are movably connected with a first leg 17 through a third bearing, and a second motor 18 is fixedly installed on the end of the first leg 17 away from the first conveying belt 14 through a first support plate, one end of the first column shaft 15 passes through the first leg 17 and is fixedly connected to the output shaft of the second motor 18, and the second motor 18 can be driven to drive the output shaft of the first column shaft 15 to drive the first column shaft 15 to drive the second column shaft 16 to drive the first column shaft 15 to drive the second column shaft 16 to drive the first column shaft 15 to drive the second column shaft 16 to drive the first column shaft 15 to drive the second column shaft 16 to drive the first column shaft 15 to drive the first column shaft 15 to drive the second column shaft 16 to drive the first column shaft 15 to drive the first column shaft 15 to drive the first column shaft 16 ...6 to drive the first column shaft 15 to drive the first column shaft 16 to drive the first column shaft 16 to drive the first column shaft 15 to drive the first column shaft 16 to drive the first column shaft 16 to drive the first column When the shaft 15 and the first conveyor belt 14 rotate, the first conveyor belt 14 drives the top tube body to move to one side, so that when it moves to the bottom of the cutting assembly, the cutting assembly cuts it, thereby improving the convenience of the installation, enhancing the safety of the device, and avoiding the tube body from being offset due to force when the staff pushes the tube body to move; at the same time, when the first conveyor belt 14 rotates, it can drive the second column shaft 16 to rotate at one end of the two groups of first legs 17 through the third bearing, so that the second column shaft 16 supports the end of the first conveyor belt 14 away from the first column shaft 15, so that the first conveyor belt 14 can operate normally.

[0041] See also Figure 1 and Figure 6, the limiting component includes a rubber pressing column 19. A extending shaft 20 is fixedly connected to the axis of the rubber pressing column 19. Clamping blocks 21 are fixedly connected to both ends of the extending shaft 20. Limiting frames 22 are fixedly connected to both ends of the clamping blocks 21. A powerful spring 23 is fixedly connected to the top of the clamping blocks 21. A support frame 24 is fixedly connected to the top of the powerful spring 23. The support frame 24 can limit the top of the powerful spring 23, causing the clamping blocks 21 to drive the limiting frames 22 and the rubber pressing column 19 to move downward, squeezing the tops of different-shaped pipe bodies, thereby limiting them. Due to the shape of the limiting frames 22, when limiting a circular pipe body, the limiting frames 22 can push the circular pipe body towards the middle, making the pipe body stay at the center. When the cutting component cuts the pipe body, the stability of the pipe body can be improved, avoiding manual holding of the pipe body, enhancing the convenience of the device. At the same time, when the first conveyor belt 14 drives the pipe body to move to one side after the pipe body is cut, the rubber pressing column 19 can rotate around the extending shaft 20, limiting the pipe body while assisting the pipe body to move to one side.

[0042] Please refer to Figure 1 , Figure 7 and Figure 8 , the cutting component includes a cutting device 25. A sliding sleeve 26 is fixedly connected to the top of the cutting device 25. A second motor 27 is installed in the inner cavity of the sliding sleeve 26. A rotating gear 28 is fixedly connected to the output shaft of the second motor 27. The rotating gear 28 is meshed with a first toothed plate 29. By driving the second motor 27, the output shaft can drive the rotating gear 28 to rotate. When the rotating gear 28 moves up and down through the first toothed plate 29, it drives the cutting device 25 to move up and down. When the cutting device 25 slowly moves downward, it cuts the pipe body into the required size, facilitating subsequent processing and avoiding manual cutting that may cause the sparks generated during cutting to burn the human body.

[0043] Please refer to Figure 1 , Figure 7 and Figure 8 , a support shaft 30 is fixedly connected to the inner cavity of the sliding sleeve 26 through a fourth bearing. A connecting gear 31 is fixedly connected to the end of the support shaft 30 away from the fourth bearing. The connecting gear 31 is meshed with a second toothed plate 32. When the sliding sleeve 26 moves up and down, it can drive the connecting gear 31 to move up and down at one end of the sliding sleeve 26 through the support shaft 30, thereby maintaining the balance of both ends of the sliding sleeve 26, improving the stability of the sliding sleeve 26, and avoiding the height deviation of both ends of the sliding sleeve 26 during use, which may affect the cutting of the pipe body by the cutting device 25.

[0044] Please refer to Figure 1 and Figure 9, the second conveying component includes a second conveyor belt 33. A third column shaft 34 is movably inserted into the inner cavity of the second conveyor belt 33. Both ends of the third column shaft 34 are movably connected to a second leg 35 through a fifth bearing. One end of the second leg 35 away from the second conveyor belt 33 is fixedly connected to a third motor 36 through a second support plate. One end of the third column shaft 34 penetrates through the second leg 35 and is fixedly connected to the output shaft of the third motor 36. By driving the third motor 36, when its output shaft drives the third column shaft 34 and the second conveyor belt 33 to rotate, the second conveyor belt 33 conveys the cut pipe body to one side, which helps to improve the convenience of the installation. While reducing the handling of the staff, it avoids the sharpness of the cut of the pipe body, and during the handling process of the staff, it scratches the staff.

[0045] Please refer to Figure 1-2 , a fourth column shaft 37 is movably inserted into one end of the inner cavity of the second conveyor belt 33 away from the third column shaft 34. Both ends of the fourth column shaft 37 are movably connected to a third leg 38 through a sixth bearing. When the second conveyor belt 33 rotates, it can drive the fourth column shaft 37 to rotate at one end of two groups of third legs 38 through the sixth bearing respectively, so that the fourth column shaft 37 supports the inner cavity of one end of the second conveyor belt 33 away from the third column shaft 34. Thus, the second conveyor belt 33 can operate normally during use and drive the pipe body to move.

[0046] Please refer to Figure 1 , two groups of support connecting plates 39 are fixedly connected between the second leg 35 and the third leg 38. One end of a group of support connecting plates 39 away from the second conveyor belt 33 is fixedly connected to one end of the extension rod 11. The support connecting plate 39 can be erected through the second leg 35 and the third leg 38 and support the extension rod 11, so that the two groups of extension rods 11 respectively support both ends of the support rod 10. Thus, the stability of the support rod 10 is enhanced through the extension rod 11, avoiding the deviation of the slider 9 during use and affecting the accuracy when the clamping rod 4 compares and measures the pipe body.

[0047] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description.
