The roller brush cleaning device 33 is slidably assembled inside the arched frame 31, and the upper surface of the roller brush cleaning device 33 is uniformly provided with through holes 332; The arched frame 31 has symmetrically fixed purge pipes 34 on the front and rear sides of its upper surface, and the output end passes through the upper surface of the arched frame 31.
[0024] Specifically, in this embodiment, the support frame 1 is rectangular in shape, with legs at the bottom and an operating platform on the top; the hydraulic cylinder 32 is connected to an external hydraulic device for operation; Furthermore, the car seat frame to be cut is pushed and transferred on the rolling moving bracket 2 to facilitate cutting with the moving cutting mechanism 4. During the cutting process, cooling water is sprayed from the external cooling pipes to cool it down. After cutting, the frame passes through the car seat frame surface debris cleaning device 3 to clean the surface debris. More specifically, the car seat frame surface debris cleaning device 3 purges the pipes during operation. 34. Continuously supplying cold air to cool the cut skeleton while simultaneously cleaning it through the roller brush cleaning device. 33. Cleaning debris, achieving mechanical cleaning of debris from the surface of the cut car seat frame; Understandably, this device can also be used for cutting metal sheets and pipes and cleaning surface debris.
[0025] In some embodiments, the roller brush cleaning device 33 includes: U-shaped right-angle plate 331, with its opening facing downwards; The U-shaped right-angle plate 331 is slidably assembled inside the arched frame 31, and the through holes 332 are evenly opened on the top surface of the U-shaped right-angle plate 331; The inner wall of the U-shaped right-angle plate 331 is rotatably fitted with round rollers 333 on both the front and rear sides, and there are three round rollers 333 distributed laterally; The outer wall of the circular roller 333 is fitted with a bristle sleeve 334; The front wall of the U-shaped right-angle plate 331 has a rectangular groove 335 along the length direction, and the bottom surface of the groove is fixedly equipped with a drive motor 336 at the front end of the corresponding circular roller 333. The bottom surface of the rectangular groove 335 through the output rear end of the drive motor 336 is coaxially fixedly connected to the front end shaft of the corresponding circular roller 333.
[0026] Specifically, in this embodiment, the top center of the U-shaped right-angle plate 331 is fixedly connected to the lower end of the hydraulic cylinder 32; the drive motor 336 is specifically a geared motor used to drive the roller 333 and the brush sleeve 334 to rotate, and the rotating brush sleeve 334 is used to clean the debris on the surface of the car seat frame. Furthermore, three circular rollers 333 are distributed parallel to each other along the feeding and discharging direction of the support frame 1, which clean the debris on the surface of the cut car seat frame multiple times. More specifically, the hydraulic cylinder 32 extends and retracts to drive the roller brush cleaning device 33 to rise and fall, thereby causing the bristles 3342 of the rotating brush sleeve 334 to contact the cut surface of the car seat frame and clean the debris on its surface.
[0027] In some embodiments, the bristle sleeve 334 includes: The sleeve 3341 is sleeved and wrapped around the outer wall of the corresponding circular roller 333; The outer wall of sleeve 3341 is evenly pasted and fixed with bristles 3342.
[0028] Specifically, in this embodiment, the bristles 3342 are made of PEEK material. PEEK bristles have a higher heat distortion temperature and a melting point range of 335-345℃. They can be used for a long time in high-temperature environments above 180 degrees Celsius, maintaining good toughness and bending recovery, and are resistant to aging and deformation. Furthermore, the sleeve 3341 is clamped to the outer wall of the roller 333 to remain fixed. After applying external force, the sleeve 3341 can be disassembled, which facilitates the overall replacement of the sleeve 3341 and the bristles 3342.
[0029] In some embodiments, a sleeve limiting structure 5 is fitted between the inner annular surface of the brush-brush sleeve 334 and the outer wall of the corresponding circular roller 333, comprising: Strip-shaped protrusion 52 is integrally formed on the outer wall of the round roller 333 along its length; The inner ring of the brush sleeve 334 has a corresponding strip-shaped protrusion 52 and a strip-shaped groove 51. The strip-shaped protrusion 52 is inserted into the corresponding strip-shaped groove 51.
[0030] Specifically, in this embodiment, the strip-shaped protrusion 52 is inserted into the strip-shaped groove 51 for positioning, effectively preventing relative rotation between the brush sleeve 334 and the round roller 333; Understandably, the two ends of the roller 333 are fixedly connected to the inner wall of the U-shaped right-angle plate 331 and the shaft of the drive motor 336 through flanges, respectively. The roller 333 is disassembled by removing the bolts on the flange. After removing the roller 333, the brush sleeve 334 is disassembled and replaced from the end. The roller 333 is installed by reversing the operation.
[0031] In some embodiments, the purging conduit 34 includes: The exhaust pipe 341 has an output pipe 343 fixedly connected to its bottom surface along the length direction via a connecting pipe; The lower end of the output tube 343 penetrates the upper surface of the arched frame 31; The exhaust pipe 341 has a closed end near the middle of the upper surface of the arched frame 31, and the other end of the exhaust pipe 341 is fixedly connected to the intake pipe 342; The intake pipe 342 connects to an external air source.
[0032] Specifically in this embodiment, the intake pipe 342 is used to connect to an external high-pressure gas source for intake, and the high-pressure gas is ejected from the output pipe 343 through the exhaust pipe 341; Furthermore, the high-pressure airflow blows across the cut car seat frame after it has been cleaned by the brush 3342, further removing debris from the car seat frame.
[0033] In some embodiments, the lower end of the air inlet pipe 342 is inclined and bent toward the feed side of the upper surface of the support frame 1; The bottom surface of the arched frame 31 is provided with a reserved inclined hole at the lower end of the inclined bend of the air pipe 342, and the lower end of the inclined bend of the air pipe 342 is located in the corresponding reserved inclined hole. The bend design at the lower end of the air pipe 342 changes the direction of the air blowing force, which blows the debris toward the first rectangular window 13, making it easier to collect the debris. It is understandable that the bristles 3342 rotate with the roller 333 and will not continuously block the debris, so that the debris can be blown towards the first rectangular window 13. In other embodiments, baffles may be provided at the front and rear edges of the upper surface of the cavity plate 11 to prevent debris from spilling out.
[0034] In some embodiments, the support frame 1 includes: A rectangular frame 12, with a hollow plate 11 fixedly mounted on its upper end; A first rectangular window 13 is provided at the right end of the cavity plate 11; A second rectangular window 15 is provided on the top feed side of the cavity plate 11, and a mesh plate 16 is fixedly installed inside it.
[0035] Specifically, in this embodiment, the cavity plate 11 has a rectangular cavity inside, and the first rectangular window 13 has the same size as and overlaps with the rectangular cavity, which facilitates the cleaning of debris collected inside the cavity plate 11. Furthermore, the mesh panel 16 serves a certain shielding function to prevent debris from falling into the cavity panel 11; It is understandable that external tools, such as scrapers at the end of long rods, can be used when cleaning debris collected inside the cavity plate 11.
[0036] In some embodiments, a drawer 14 is inserted into the second rectangular window 15, and a handle is fixedly fitted on its outer wall. With the arrangement of the drawer 14, debris falling into the first rectangular window 13 will fall into the drawer 14, and gripping the handle makes it easy to pull out and insert the drawer 14.
[0037] In some embodiments, the rolling movable support 2 includes: The first rectangular rod 21 and the second rectangular rod 22 are fixedly assembled along the length direction on the front and rear sides of the middle of the top surface of the support frame 1; The first rectangular rod 21 and the second rectangular rod 22 are rotatably fitted with round rods 23 on their opposite faces, and the round rods 23 are evenly distributed along the length direction of the first rectangular rod 21 and the second rectangular rod 22; The top surfaces of the first rectangular rod 21 and the second rectangular rod 22 extend from the upper end of the round rod 23.
[0038] Specifically, in this embodiment, the round rod 23 can rotate on the opposite surfaces of the first rectangular rod 21 and the second rectangular rod 22. The upper end of the round rod 23 extends out to fit the top surfaces of the first rectangular rod 21 and the second rectangular rod 22 against the car seat frame placed on the upper end of the rolling moving bracket 2. As the round rod 23 rotates by pushing and pulling the car seat frame, the pushing and pulling friction of the car seat frame is reduced, and the movement is smoother. It is understandable that the rolling moving bracket 2 does not have a drive mechanism and is used in conjunction with the manual pushing and pulling of the car seat frame.
[0039] In some embodiments, the movable cutting mechanism 4 includes: The first electric push rod 41 has its lower end fixedly assembled to the material discharge side of the front wall of the support frame 1; The upper telescopic end of the first electric push rod 41 is fixedly equipped with one end of the linear module 42, and the other end of the linear module 42 extends backward to the top of the support frame 1. The slider of the linear module 42 is fixedly mounted with a second electric push rod 43 facing downwards, and a cutting machine 44 is fixedly mounted on its telescopic lower end.
[0040] Specifically in this embodiment, both the first electric push rod 41 and the second electric push rod 43 are connected to an external power supply and a controller. The controller is used to control the extension and retraction strokes of the first electric push rod 41 and the second electric push rod 43. This control method is a conventional application of the controller. Furthermore, the first electric push rod 41 drives the linear module 42, the second electric push rod 43, and the cutting machine 44 to move up and down; the slider of the linear module 42 drives the second electric push rod 43 and the cutting machine 44 to move back and forth; the second electric push rod 43 drives the cutting machine 44 to move up and down, and the first electric push rod 41 and the second electric push rod 43 work together to better control the height of the cutting machine 44; More specifically, the cables connecting the second electric push rod 43 and the cutting machine 44 are provided with a reserve, so that they can move with the second electric push rod 43 and the cutting machine 44; It is understandable that the main body of the cutting machine 44 is the cutting motor, and the cutting head is fixedly mounted on the shaft of the cutting motor.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
