[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example: Please refer to Figure 1 and Figure 2This embodiment provides a rolling cutting mechanism for machining blind holes. The mechanism includes a frame (not shown). The frame is provided with a pulling roller 1 for conveying blind slats. The pulling roller 1 is equipped with a corresponding drive device for rotating the pulling roller 1. The drive device rotates the pulling roller 1, thereby conveying the blind slats accordingly. The frame is also provided with a mounting frame 2, which is positioned away from the pulling roller 1 in the conveying direction of the blind slats. A first rotating shaft 3 and a second rotating shaft 4 are rotatably connected to the mounting frame 2. The bottoms of the first and second rotating shafts 3 and 4 extend downwardly from the bottom wall of the mounting frame 2. A first processing wheel 5 is provided at the bottom of the first rotating shaft 3, and a second processing wheel 6 is provided at the bottom of the second rotating shaft 4. A gap is provided between the first and second processing wheels 5 and 6 to allow the blind slats to pass through. The specific width of the gap can be determined based on the actual thickness of the blind slats. The first and second processing wheels 5 and 6 are positioned so that the blind slats conveyed by the pulling roller 1 can pass between the first and second processing wheels 5 and 6. A plurality of grooves 7 are provided on the wheel wall of the first processing wheel 5. The specific number of the grooves 7 can be determined according to the actual number of rows of shutter holes that need to be opened on the shutter. The wheel wall of the second processing wheel 6 is provided with rolling cutting rings 8 that are arranged one-to-one with the grooves 7. Each rolling cutting ring 8 is arranged to extend into the corresponding groove 7. Each rolling cutting ring 8 is provided with a plurality of breaking parts 9 to form a plurality of rolling cutting blocks 10. The number and width of the breaking parts 9 can be determined according to the actual situation. The required spacing between each row of shutter holes and the length of the shutter holes to be formed are determined.

[0023] To facilitate the cutting of the louver blades, the sidewall of each rolling ring 8, away from the second processing wheel 6, is inclined to form a pointed structure. The pointed structure enables the rolling ring 8 to more easily break the louver blade when it contacts the louver blade. The inclination of the pointed structure is specifically determined according to the shape of the louver hole. In actual use, the groove 7 can also be provided with an inclined wall adapted to the pointed structure to cooperate with the pointed structure to squeeze the position of the broken louver blade to meet the processing requirements of the louver hole shape. At the same time, each rolling block 10 is provided with an arc angle 11 at both ends. The setting of the arc angle 11 allows the rolling block 10 to more easily cut into the louver blade and remove from the louver blade when rotating with the second punching, thereby making it easier to cut the louver hole in the louver blade. The specific curvature of the arc angle 11 is determined according to the size of the arc portion of the louver hole to be cut.

[0024] Through the above-mentioned arrangement, when it is necessary to process holes in the louver sheet, the louver sheet transported by the traction roller 1 will pass between the first processing wheel 5 and the second processing wheel 6. Afterwards, by rotating the first processing wheel 5 and the second processing wheel 6, the rolling block 10 can penetrate into the groove 7, so that the rolling block 10 at the corresponding position can cut the passing louver sheet when following the rotation of the second processing wheel 6, so that corresponding louver holes can be cut out on the louver sheet. The interruption part 9 plays the role of providing spacing, which can leave the required spacing between the louver holes processed by the first processing wheel 5 and the second processing wheel 6 and control the length of the formed louver holes, that is, when the length of the interruption part 9 changes, the length of the corresponding rolling block 10 will also change, and then the length of the cut louver hole and the spacing between the louver holes in the same row will also change. At the same time, the grooves 7 provided in the annular structure prevent the rolling block 10 from interfering with the first processing wheel 5 when the first processing wheel 5 and the second processing wheel 6 rotate forward and reverse, thereby avoiding the phenomenon that the rolling block 10 is damaged by the first processing wheel 5 during the reversal process due to the gap in the gear transmission. In addition, in actual use, multiple first processing wheels 5 with different distribution forms of grooves 7 and multiple second processing wheels 6 with different distribution forms of rolling rings 8 and breaking parts 9 can be produced. In the actual processing process, according to the actual processing requirements of the actual blinds, the first processing wheels 5 and the second processing wheels 6 of appropriate styles can be replaced on the first rotating shaft 3 and the second rotating shaft 4 to complete the appropriate processing work. The first processing wheel 5 and the second processing wheel 6 can be detachably connected to the first rotating shaft 3 and the second rotating shaft 4 in a common detachable connection manner, such as a key connection, for easy use.

[0025] In this embodiment, the mounting frame 2 is provided with symmetrically arranged mounting holes 12, wherein a fixed sleeve 13 is fixedly disposed in one of the mounting holes 12, and an eccentric sleeve 14 is rotatably connected in the other mounting hole 12. The eccentric sleeve 14 is eccentrically arranged relative to the corresponding mounting hole 12. The first rotating shaft 3 penetrates into the fixed sleeve 13, and the second rotating shaft 4 penetrates into the eccentric sleeve 14. The second rotating shaft 4 and the eccentric sleeve 14 are coaxially arranged. The first rotating shaft 3 is rotatably connected in the fixed sleeve 13, and the second rotating shaft 4 is rotatably connected in the eccentric sleeve 14. A first bevel gear 15 is rotatably connected to the top of each of the fixed sleeve 13 and the eccentric sleeve 14. The penetration ends of the first rotating shaft 3 and the second rotating shaft 4 are fixedly connected to the first bevel gear 15 at the corresponding positions. The mounting frame 2 is also provided with a drive assembly for driving the first bevel gear 15 to rotate. The drive assembly includes mounting blocks 16 symmetrically arranged on the mounting frame 2. A drive shaft 17 is movably inserted between the mounting blocks 16 on both sides. The drive shaft 17 is rotatably connected to the mounting blocks 16 via bearings 18. The drive shaft 17 is provided with a second bevel gear 19 arranged in a one-to-one correspondence with the first bevel gear 15. The second bevel gear 19 meshes with the corresponding first bevel gear 15. A transmission sprocket 20 is also fixedly provided on the drive shaft 17. The transmission sprocket 20 is used to connect to an external transmission motor via a transmission chain. The mounting frame 2 is also provided with a protective cover 21. The protective cover 21 covers the first bevel gear 15 and the second bevel gear 19 inside to prevent external impurities from damaging the first bevel gear 15 and the second bevel gear 19.

[0026] Through the above-mentioned setting, when the external transmission motor starts working, it can drive the transmission sprocket 20 to rotate through the transmission chain, thereby driving the drive shaft 17 to rotate. After the drive shaft 17 rotates, it can drive the second bevel gear 19 to rotate, so that the first bevel gear 15 can follow the rotation, and then drive the first rotating shaft 3 and the second rotating shaft 4 to rotate, so as to realize the rotation of the first processing wheel 5 and the second processing wheel 6. At the same time, the setting of the eccentric sleeve 14 allows the eccentric sleeve 14 to change the position of the second rotating shaft 4 when rotating in the mounting hole 12, so as to achieve fine-tuning of the distance between the first rotating shaft 3 and the second rotating shaft 4, and then achieve adjustment of the distance between the first processing wheel 5 and the second processing wheel 6, so as to adapt to the different plate thicknesses of the blinds. It should be noted that this adjustment distance should be small to avoid the phenomenon of separation between the first bevel gear 15 and the second bevel gear 19.

[0027] To facilitate the use of the eccentric sleeve 14, a plurality of rotation holes 22 are provided on the outer wall of the eccentric sleeve 14. The distribution of the rotation holes 22 on the eccentric sleeve 14 can be determined according to specific circumstances. By providing the rotation holes 22, a worker can conveniently rotate the eccentric sleeve 14 by inserting a tool such as a wrench into the rotation holes 22. At the same time, a fixing plate 23 is fixedly provided on the bottom surface of the mounting frame 2. The fixing plate 23 is provided with a fixing hole 24. The eccentric sleeve 14 is provided through the fixing hole 24. The diameter of the fixing hole 24 is slightly larger than the outer diameter of the eccentric sleeve 14. The fixing plate 23 is also provided with a deformation gap 25. The deformation gap 25 is connected to the fixing hole 24, and one side end of the deformation gap 25 is provided through the fixing plate 23. The fixing plate 23 is also provided with a locking hole 26. The locking hole 26 is perpendicular to the deformation gap 25 and is provided through the deformation gap 25. A locking screw is inserted into the locking hole 26. Through the above-mentioned arrangement, after the eccentric sleeve 14 rotates to adjust the distance between the first rotating shaft 3 and the second rotating shaft 4, the locking screw is locked into the locking hole 26. After the locking screw is inserted into the locking hole 26, it can squeeze the deformation gap 25, so that the fixing plate 23 undergoes adaptive deformation in the deformation gap 25, thereby changing the aperture of the fixing hole 24, so that the fixing hole 24 can clamp the eccentric sleeve 14, thereby fixing the eccentric sleeve 14 on the mounting frame 2, and preventing the eccentric sleeve 14 from rotating during the rotation of the second rotating shaft 4 and affecting the progress of the processing work.

[0028] The working principle of the present invention is that when working, the common vertical installation method or horizontal installation method can be selected to install the rolling cutting mechanism according to actual conditions, that is, the position of the rolling cutting mechanism can be adjusted accordingly according to whether the shutter pieces need to be transported horizontally or vertically, and the first processing wheel 5 and the second processing wheel 6 of the appropriate style can be selected to be installed on the first rotating shaft 3 and the second rotating shaft 4. Afterwards, by making the traction roller 1 and the drive shaft 17 start to rotate, the specific rotation speed can be determined according to the actual required conveying speed, and the louver piece that needs to be processed with holes will be conveyed by the traction roller 1 to between the first processing wheel 5 and the second processing wheel 6. Since the rolling block 10 can penetrate into the groove 7, the rolling block 10 at the corresponding position can cut the passing louver piece when rotating with the second processing wheel 6, so that corresponding louver holes can be cut on the louver piece. The first processing wheel 5 and the second processing wheel 6 can also convey the louver piece while cutting the louver piece. The louver piece output by the first processing wheel 5 and the second processing wheel 6 is the louver piece with the corresponding louver hole processed.

Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
