[0025] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In the embodiments of the present invention, the terms "first" and "second" are used solely for descriptive purposes to distinguish objects, such as substances, from one another and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. For example, a first XX could also be referred to as a second XX, and similarly, a second XX could also be referred to as a first XX, without departing from the scope of the embodiments of the present invention. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of such features.

[0027] It should be understood that when an element is referred to as being "connected," "coupled," "engaged," "attached," "secured," "abutted," etc. to another element, it can be directly connected to the other element or an indirect connection may exist. In contrast, when an element is referred to as being "directly connected," "directly coupled," etc. to another element, there are no intervening elements. Other words used to describe the relationship between elements should be interpreted in a similar manner (e.g., "between" versus "directly between," "adjacent" versus "directly adjacent," etc.).

[0028] See also Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the three-dimensional structure assembly of a bead turning machine provided by the utility model. Figure 2 for Figure 1 The bead turning machine 100 provided in the embodiment of the present invention is used to process a workpiece 200 to be processed. The workpiece 200 to be processed can be jewelry or accessories with a circular or curved surface. The bead turning machine 100 can be used for turning beads and engraving and patterning jewelry beads.

[0029] The ball turning machine 100 includes a frame 10, a feeding device arranged on the frame 10, a clamping mechanism 50, a processing mechanism 60 and a detection mechanism 70. The feeding device includes a feeding mechanism 20, a waiting mechanism 30 and a loading mechanism 40 connected and arranged. The feeding assembly 20 is used to feed the workpiece 200 to be processed. Figure 1 In the XYZ coordinate system shown, in the X-axis direction, the feeding mechanism 20, the waiting mechanism 30 and the clamping mechanism 50 are connected in sequence. The waiting mechanism 30 receives the workpiece to be processed 200 transmitted by the feeding component 20. The loading mechanism 40 is used to move the workpiece to be processed 200 from the waiting mechanism 30 to the processing space 500 of the clamping mechanism 50. The processing mechanism 60 is arranged in the Y-axis direction of the clamping mechanism 50, corresponding to the workpiece to be processed 200, and is used to process the workpiece to be processed 200. The detection mechanism 70 is fixed to the processing mechanism 60, corresponding to the processing space 500, and is used to obtain image information of the processing space 500.

[0030] The feeding mechanism 20 includes a vibration plate connecting base 21, a vibration plate 23, and a feeding channel 25. The vibration plate connecting base 21 is fixed to the frame 10. The vibration plate 23 is mounted on the vibration plate connecting base 21. The vibration plate 23 vibrates at a predetermined frequency. The vibration plate 23 has a discharge port 231, which is connected to one end of the feeding channel 25. The workpiece 200 to be processed slides into the feeding channel 25 through the discharge port 231. In this embodiment, the feeding channel 25 is tubular.

[0031] See also Figure 2 and Figure 3 , Figure 3 for Figure 2 The figure shows a schematic diagram of the three-dimensional assembly structure of the material-waiting mechanism. The material-waiting mechanism 30 is connected to the loading channel 25, which extends toward the material-waiting mechanism 30 and is inclined toward the negative half-axis of the Z axis. The material-waiting mechanism 30 includes an adjustment slide 31, a rotating power assembly 32, a base plate 33, a first transmission shaft 34, a second transmission shaft 35, a guide frame 36, an inductor mounting frame 37, and an inductor 38. The adjustment slide 31, the rotating power assembly 32, and the base plate 33 are fixed in sequence along the positive half-axis of the Z axis. The first transmission shaft 34, the second transmission shaft 35, and the guide frame 36 are fixed to the base plate 33. The inductor mounting frame 37 is fixed to the rotating power assembly 32, and the inductor 38 is fixed to the inductor mounting frame 37.

[0032] See also Figure 4and Figure 5 , Figure 4 for Figure 3 The schematic diagram of the partial three-dimensional structure of the waiting mechanism at one angle is shown. Figure 5 for Figure 3 A schematic diagram of a partial three-dimensional structure decomposition of the material-waiting mechanism from another angle is shown. The adjustment slide 31 includes a first adjustment block 311, a second adjustment block 312, a third adjustment block 313, a first adjustment rod 314, a second adjustment rod 315, and a third adjustment rod 316, which are used to fine-tune the position of the rotating power assembly 32 in the Y-axis and Z-axis directions. The first adjustment block 311 and the second adjustment block 312 are connected by a slide rail structure extending along the Y-axis direction, and the first adjustment block 311 is provided with a first sliding hole 3111 extending along the Y-axis direction, and the second adjustment block 312 is provided with a column 3121 with a through hole extending along the X-axis direction. The column 3121 is inserted into the first sliding hole 3111, and the first adjustment rod 314 passes through the first adjustment block 311 and is inserted into the column 3121. By adjusting the first adjustment rod 314, the second adjustment block 312 moves relative to the first adjustment block 311 along the Y-axis, and the third adjustment block 313 moves synchronously with the second adjustment block 312. The first adjustment rod 314 can be a threaded adjustment rod that engages with the cylinder 3121 and is rotated to adjust the position of the second adjustment block 312. The second adjustment block 312 and the third adjustment block 313 are connected by a slide rail and slider structure extending along the Z-axis. The second adjustment rod 315 passes through the second adjustment block 312 and is inserted between the slide rail of the second adjustment block 312 and the slider of the third adjustment block 313. The second adjustment block 312 is provided with a second slide hole 3122 extending along the Z-axis. The third adjustment rod 316 passes through the second slide hole 3122 and the third adjustment block 313 in sequence. By adjusting the second adjusting rod 315, the third adjusting block 313 will move relative to the second adjusting block 312 along the Z-axis direction. After the adjustment is completed, the third adjusting rod 316 is locked with the second sliding hole 3122. The second adjusting rod 315 can be a toothed adjusting rod, which engages with the slider of the third adjusting block 313 and adjusts the position of the third adjusting block 313 by rotation.

[0033] The rotary power assembly 32 includes a first mounting seat 321, a first rotary drive member 322, a bearing rod 323, a bearing 324, a driving pulley 325, and a belt 326. The first mounting seat 321 is fixed to the third adjustment block 313. The position of the first mounting seat 321 in the Y-axis and Z-axis directions can be adjusted by adjusting the slide 31. The base plate 33 is fixed to the first mounting seat 321, forming a receiving space 3210. The first rotary drive member 322 is fixed to the receiving space 3210. The bearing rod 323 extends through the first mounting seat 321 and is sleeved within the bearing 324. The bearing 324, the driving pulley 325, the belt 326, the first transmission shaft 34, and the second transmission shaft 35 are connected by the belt 326.

[0034] The first transmission shaft 34 and the second transmission shaft 35 are relatively spaced apart and disposed on a surface of the base plate 33 away from the first rotary drive member 322, forming a workpiece channel 340. The width of the workpiece channel 340 is set corresponding to the diameter of the workpiece 200 to be processed. The first rotary drive member 322 drives the first transmission shaft 34 and the second transmission shaft 35 to rotate so that the inner holes of the workpiece 200 to be processed are arranged in an orderly manner in the workpiece channel 340. The adjustment slide 31 can adjust the position of the first mounting seat 321 by adjusting the relative positions of the first adjustment block 311 and the second adjustment block 312 in the Y-axis direction, thereby adjusting the position of the workpiece channel 340 in the Y-axis direction. Similarly, the workpiece channel 340 can be adjusted in the Z-axis direction by adjusting the relative positions of the second adjustment block 312 and the third adjustment block 313 in the Z-axis direction to align with the loading mechanism 40.

[0035] The guide frame 36 is fixed to the surface of the base plate 33 away from the first rotary drive member 322 and is located at the entrance of the workpiece channel 340. This is connected to the loading channel 25 of the feed mechanism 20. It is arranged in a "J" shape, spanning both sides of the first transmission shaft 34 and the second transmission shaft 35. The loading channel 25 passes through the guide frame 36, guiding the workpiece 200 to be processed into the workpiece channel 340. A sensor mounting frame 37 is mounted on the first mounting seat 321. A sensor 38 is mounted on the sensor mounting frame 37 and positioned corresponding to the detection position 3400 to detect whether a workpiece 200 to be processed is present at the detection position 3400 of the workpiece channel 340.

[0036] The belt 326 may be a polyurethane round belt.

[0037] It is understandable that the first rotary drive member 322 may be a rotary motor, and the rotary power assembly 32 may also be other power-providing devices, as long as they can drive the first transmission shaft 34 and the second transmission shaft 35 to rotate.

[0038] See also Figure 6-7 , Figure 6 for Figure 1 The three-dimensional structural assembly diagram of the feeding mechanism is shown in FIG. Figure 7 for Figure 6The figure shows an exploded perspective view of the three-dimensional structure of the feeding mechanism. The feeding mechanism 40 includes a feeding rail 411, a first driving member 412, a feeding rack 413, a second driving member 414, a balancing block 415, a suction rod assembly 416, and a guide assembly 417. The feeding rail 411 extends along the X-axis direction, that is, the feeding rail 411 extends from the waiting mechanism 30 to the clamping mechanism 50. The first driving member 412 drives the feeding rack 413 to move along the feeding rail 411. The second driving member 414 is fixed to the feeding rack 413, and the driving rod 4141 of the second driving member 414 passes through the balancing block 415 and is fixedly connected to the suction rod assembly 416. Guide assembly 417 includes a linear bearing 4171 and a linear guide shaft 4172. Linear bearing 4171 is fixed to feed frame 413 and is fitted with linear guide shaft 4172. Linear guide shaft 4172 extends through feed frame 413 and is fixed to balance block 415. When the drive rod 4141 of the second drive member 414 extends or retracts along the Z-axis, balance block 415 and linear guide shaft 4172 move synchronously with it. The linear guide shaft 4172 and linear bearing 4171 work together to maintain linear motion, thereby enhancing the driving stability of the second drive member 414.

[0039] The first driving member 412 may be a servo motor, and the second driving member 414 may be a cylinder.

[0040] Among them, the feeding rack 413 is provided with a strip hole corresponding to the linear guide shaft 4172, which can increase the fault tolerance rate.

[0041] The suction rod assembly 416 includes a suction rod head 4161, a vacuum head 4162, and an air pipe connector 4163. The suction rod head 4161 is fixed to the end of the drive rod 4141. The vacuum head 4162 is located at the end of the suction rod head 4161 and reciprocates along the Z axis driven by the drive rod 4141. The air pipe connector 4163 is located in the Y axis direction of the suction rod head 4161. The vacuum head 4162 is used to suck the workpiece 200 to be processed from the workpiece channel 340. The vacuum head 4162 may be a rubber vacuum head.

[0042] It is understandable that the nozzle diameter of the vacuum suction head 4162 is smaller than the diameter of the workpiece 200 to be processed. Moreover, those skilled in the art can replace the vacuum suction head 4162 with a nozzle of different diameter to adapt to workpieces 200 to be processed with different diameters.

[0043] Please refer to Figure 2 、 8 and 9, Figure 8 for Figure 2 The three-dimensional structural assembly diagram of the clamping mechanism is shown at one angle. Figure 9 for Figure 2A schematic diagram of the three-dimensional structure assembly of the clamping mechanism from another angle is shown. The clamping mechanism 50 includes a mounting plate 51, at least two clamping groups disposed on the mounting plate 51, and a top assembly 54. The top assembly 54 and the clamping groups are disposed on opposite sides of the mounting plate 51, with each clamping group corresponding to one top assembly 54. The clamping group includes at least two clamping units 520. In this embodiment, the at least two clamping groups include a first clamping group 52 and a second clamping group 53. The first clamping group 52 includes two clamping units 520 disposed opposite each other along the X-axis, and the second clamping group 53 includes two clamping units 520 disposed opposite each other along the Y-axis. There are two top-to-top components 54. The first top-to-top component 541 is set corresponding to the first clamping group 52, and is used to drive the two clamping units 520 of the first clamping group 52 to move relative to or opposite to each other along the X-axis direction. The second top-to-top component 542 is set corresponding to the second clamping group 53, and is used to drive the two clamping units 520 of the second clamping group 53 to move relative to or opposite to each other along the Y-axis direction, so that the four clamping units 520 clamp the workpiece 200 to be processed in the processing space 500 from four different directions.

[0044] It is understandable that in other embodiments, the number of clamping groups may be three, four, five, etc., as long as they can clamp the workpiece 200 to be processed in the processing space 500 .

[0045] See also Figure 10 and 11 , Figure 10 for Figure 2 The schematic diagram of the three-dimensional structure of the clamping unit is shown. Figure 11 for Figure 10 A cross-sectional view of the clamping unit is shown. The clamping unit 520 includes a second rotary drive member 521, an ejector shaft 523 having a groove 5231, an ejector pin 524, and a locking cap 525. The ejector shaft 523 is fixed to the second rotary drive member 521, and the ejector pin 524 is mounted in the groove 5231 for clamping the workpiece 200 to be processed. The space enclosed by the four clamping units 520 constitutes the processing space 500. The locking cap 525 can be loosely or loosely mounted on the open end of the groove 5231 to facilitate replacement of the ejector pin 524. The locking cap 525 includes a hollow cap body 5251 and a hollow spring collet 5253 disposed within the cap body 5251. The spring collet 5253 is sleeved around the ejector pin 524 and is clamped between the ejector shaft 523 and the ejector pin 524. The second rotary drive member 521 drives the ejector shaft 523 to rotate, driving the ejector 524 to rotate, and further driving the workpiece 200 to rotate, so that the processing mechanism 60 can perform all-around processing on the workpiece 200. In this embodiment, the second rotary drive member 521 can drive the ejector 524 to rotate 360 ​​degrees.

[0046] It is understood that the user can replace different types of ejector pins 524 as needed by loosening and tightening the locking cap 525 to process different workpieces 200. When the workpiece 200 to be processed is a bead with an inner hole, the four ejector pins 524 can be configured with two opposing ejector pins 524 in a group with pointed tips to fit the inner hole of the bead, and the other group of two opposing ejector pins 524 can be configured with rounded tips to fit the rounded surface of the bead.

[0047] Among them, the second rotary driving member 521 can be a rotary motor, and the ejector shaft 523 is connected to the second rotary driving member 521 through a coupling 591 to achieve synchronous rotation. The ejector shaft 523 is accommodated in the second mounting seat 592, and the second rotary driving member 521 is fixed to the second mounting seat 592 through a pad 593, and the second mounting seat 592 is connected to the mounting plate 51 through a slide rail slider structure. The ejector shaft 523 is outer-circuited with a plurality of centripetal thrust ball bearings 595, washers 596 and sealing ring deep groove ball bearings 597, washers 596 are arranged between the centripetal thrust ball bearings 595, and a bearing cover 598 is arranged between the centripetal thrust ball bearings 595 and the second mounting seat 592.

[0048] Please refer to Figure 8 、 9 and 12, Figure 12 for Figure 9 The diagram shows a schematic diagram of the three-dimensional structure of the top-to-bottom assembly. The two clamping units 520, which are positioned opposite each other along the X-axis, are a first clamping unit 520a and a second clamping unit 520b. The first top-to-bottom assembly 541 is fixed to a surface of the mounting plate 51 away from the clamping group and includes a third driving member 5411, a screw rod 5412, a first transmission member 5413, and a second transmission member 5414. The third driving member 5411 drives the screw rod 5412 in forward and reverse rotation. The first transmission member 5413 is fixed to the screw rod 5412 and the second mounting base 592 of the first clamping unit 520a. The second transmission member 5414 is fixed to the screw rod 5412 and the second mounting base 592 of the second clamping unit 520b. When the third driving member 5411 drives the screw rod 5412 to rotate forward and reverse, the first clamping unit 520a and the second clamping unit 520b can be driven to move toward or away from each other through the slide rail structure through the first transmission member 5413 and the second transmission member 5414, so that the ejector pin 524 clamps and releases the workpiece 200 to be processed.

[0049] Among them, the third driving member 5411 can be a servo motor, the first transmission member 5413 and the second transmission member 5414 can be fixedly connected to the screw 5412 through a screw nut, the first transmission member 5413 passes through the mounting plate 51 and is fixedly connected to the first clamping unit 520a, and the second transmission member 5414 passes through the mounting plate 51 and is fixedly connected to the second clamping unit 520b.

[0050] It can be understood that the structures of the two clamping units 520 and the second top assembly 542 arranged opposite to each other along the Y-axis direction are the same as the structures of the two clamping units 520 and the first top assembly 541 arranged opposite to each other along the X-axis direction, and are not repeated here.

[0051] When the clamping units 520 and the top assembly 54 are working, during the processing of the workpiece 200 to be processed, the four clamping units 520 can clamp and fix the workpiece 200 to be processed from four different directions to keep the workpiece 200 to be processed stationary; when the workpiece 200 to be processed needs to be rotated, according to the requirements of the rotation direction, the two opposite clamping units 520 clamp the beads to be processed and rotate synchronously to complete the rotation of the workpiece 200 to be processed. At this time, the top assembly 54 drives the other two clamping units 520 to move backwards to prevent its ejector pins 524 from damaging the workpiece 200 to be processed.

[0052] Further, see Figure 8 The clamping mechanism 50 also includes a material guide trough 55, a debeading plate 56, and a tool setter 57. The material guide trough 55 is located below the processing space 500. Chips generated during the processing of the workpiece 200 fall into the trough 55 and slide down the trough to the bottom of the trough 55, improving the chip recovery rate. The debeading plate 56 is fixed to the mounting plate 51, corresponding to the processing space 500, in a "7" shape, with a pointed end facing the processing space 500. The tool setter 57 is fixed to the clamping unit 520.

[0053] Further, see Figure 2 The clamping mechanism 50 also includes a swing assembly 58, which includes a left support plate 581, a right support plate 582, a speed reducer 583, a third mounting seat 584, and a third rotational drive member 585. The mounting plate 51 is in an inverted U-shape and includes a horizontal plate 511 and two vertical plates 512. The horizontal plate 511 is cross-shaped and is used to mount four clamping units 520. The four clamping units 520 are respectively mounted at the four ends of the horizontal plate 511. The two vertical plates 512 are arranged along the X-axis. The left support plate 581 and the right support plate 582 are spaced apart and oppositely arranged along the X-axis and are respectively fixed to the two vertical plates 512 on the side away from the horizontal plate 511. The speed reducer 583 is fixed to the left support plate 581 and is drivingly connected to the vertical plates 512. The third rotational drive member 585 is fixed to the speed reducer 583 via the third mounting seat 584. The third rotational drive member 585 drives the mounting plate 51 to swing in a cradle-like manner at a predetermined angle. In this embodiment, the third rotation driving member 585 may be a rotation motor, and the swing angle of the mounting plate 51 is plus or minus 110 degrees.

[0054] See also Figure 13 ,for Figure 1A schematic diagram of the three-dimensional assembly structure of the processing mechanism is shown. The processing mechanism 60 is located in the positive Z-axis direction of the clamping mechanism 50 and includes a processing support 61, an X-axis module 62, a Y-axis module 63, a Z-axis module 64, and a processing assembly 65. The processing support 61 includes a crossbeam 611 and columns 612 at both ends of the crossbeam 611. The X-axis module 62 is located on the crossbeam 611 of the processing support 61 along the X-axis direction, the Y-axis module 63 is located on the X-axis module 62 along the Y-axis direction, and the Z-axis module 64 is located on the Y-axis module 63 along the Z-axis direction. The loading slide 411 of the loading mechanism 40 is fixed to the column 612 and faces the side of the clamping mechanism 50.

[0055] The processing support 61 is preferably a gantry.

[0056] The X-axis module 62 includes an X-axis servo motor 621, an X-axis ball screw 622, an X-axis movable part 623 and an X-axis linear guide group 624 arranged on both sides of the X-axis ball screw 622.

[0068] See also Figure 16-17 , Figure 16 for Figure 1 The schematic diagram of the three-dimensional structure assembly of the detection mechanism shown in FIG. Figure 17 for Figure 16 The following is an exploded perspective view of the detection mechanism. The detection mechanism 70 is fixed to the tool magazine fixed plate 68 and includes a mounting bracket 71, a lens mount 72, a camera 73, and a protective lens 75. The lens mount 72 is rotatably mounted on the mounting bracket 71, and the camera 73 is mounted on the lens mount 72. The lens 731 of the camera 73 is housed in the lens mount 72. The lens 731 is a wide-angle telephoto lens. The protective lens 75 covers the lens 731 to prevent dust and filter UV light.

[0069] By adjusting the angle of the lens mounting seat 72 relative to the mounting bracket 71 , the lens 731 can be adjusted to align with the processing space 500 , so that the processing process and processing effect of the workpiece 200 to be processed can be more intuitively detected.

[0070] The mounting bracket 71 is provided with a first through hole 711 and an arc-shaped hole 712. The lens mounting seat 72 is provided with a second through hole 721 corresponding to the first through hole 711 and a third through hole 722 corresponding to the arc-shaped hole 712. A first bolt passes through the first through hole 711 and the second through hole 721, and a second bolt passes through the arc-shaped hole 712 and the third through hole 722. With the first bolt as a fulcrum, the mounting bracket 71 and the lens mounting seat 72 can rotate relative to each other. At this time, the third through hole 722 slides along the extending direction of the arc-shaped hole 712. When the lens 731 is rotated to align with the processing space 500, the second bolt is tightened to maintain the relative position of the mounting bracket 71 and the lens mounting seat 72, thereby achieving stable image acquisition.

[0071] When the ball turning machine 100 is working, the workpiece 200 to be processed is added to the vibration plate 23 of the feeding mechanism 20, and the vibration plate 23 vibrates, so that the workpiece 200 to be processed enters the loading channel 25 and is arranged in order, and then enters the workpiece channel 340 of the loading mechanism 30 from the loading channel 25; the first rotary driving member 322 drives the first transmission shaft 34 and the second transmission shaft 35 to rotate, so that the inner holes of the workpiece 200 to be processed are arranged in order in the workpiece channel 340; the first driving member 412 drives the feeding rack 413 to move along the loading slide rail 411 to the top of the workpiece channel 340; when the driving rod 4141 of the second driving member 414 extends along the Z-axis direction, the balancing block 415 and the linear guide shaft 4172 move synchronously therewith, keeping the driving rod 4141 extending straightly, and at the same time, the vacuum suction head 4162 moves along the negative half-axis direction of the Z-axis to the workpiece channel 340 to suck the workpiece 200 to be processed ; After the suction is completed, when the driving rod 4141 of the second driving member 414 retracts along the Z-axis direction, the balance block 415 and the linear guide shaft 4172 move synchronously therewith, keeping the driving rod 4141 retracted linearly. At the same time, the vacuum suction head 4162 moves with the workpiece to be processed 200 along the positive half-axis direction of the Z-axis; the first driving member 412 drives the feeding rack 413 to move along the loading slide rail 411 to the top of the clamping mechanism 50, and releases the workpiece to be processed 200 to the processing space 500 of the clamping mechanism 50. The clamping mechanism 50 cooperates with the processing mechanism 60 to adjust the processing surface of the workpiece to be processed 200 to the processing direction of the processing mechanism 60. The processing mechanism 60 selects a preset tool or a batching knife 673 as needed, and moves it to the processing space 500 to process the workpiece to be processed 200. At the same time, the detection mechanism 70 obtains image information of the processing space 500.

[0073] The material waiting mechanism 30 is provided with a first rotating power component 32 to drive the first transmission shaft 34 and the second transmission shaft 35 to rotate, so that the inner holes of the workpiece 200 to be processed can be arranged in order in the workpiece channel 340, preventing the suction rod component 416 of the loading mechanism 40 from being unable to absorb the workpiece 200 to be processed.

[0074] When the driving rod of the second driving member 414 of the loading mechanism 40 is extended and retracted, the balance block 415 and the linear guide shaft 4172 move synchronously therewith, thereby improving the extension and retraction stability of the second driving member 414 and improving the reliability of the loading mechanism 40 in sucking the workpiece 200 to be processed.

[0075] The clamping mechanism 50 is provided with a locking cap 525 which can be loosely or tightly mounted on the open end of the groove 5231 . By loosening or tightening the locking cap 525 , the ejector pins 524 of various styles can be replaced.

[0076] The clamping mechanism 50 drives the first clamping unit 520a and the second clamping unit 520b to move toward or away from each other through the screw rod 5412 of the ejection assembly 54, so that the ejector pin 524 can clamp or release the workpiece 200 to be processed.

[0077] The pattern cutting assembly 67 is provided with a Z-axis lifting module 671 to adjust the position of the fourth rotary drive member 672 and the pattern cutting knife 673 on the Z axis.

In addition, the second rotary motor 6722 drives the third synchronous wheel 677 to rotate, which is driven by a belt to synchronously rotate the fourth synchronous wheel 678, the bearing drive seat 675, and the pattern cutting knife 673. The pattern cutting knife 673 rotates around the Z axis to adjust the angle of the pattern cutting knife 673 and achieve 360-degree angle adjustment. The first rotary motor 6721 drives the first synchronous wheel 674 to rotate, which is driven by a belt to synchronously rotate the transition wheel 6753, the second synchronous wheel 676, and the pattern cutting knife 673, driving the pattern cutting knife 673 to rotate around its center of circle, achieving self-rotating pattern cutting processing.
