The moving part 6 can be a screw that drives the cutting piece 5 to move on the workbench 1, or it can be driven by a cylinder to drive the cutting piece 5 to slide on the workbench 1. When the placement plate 4 moves to the processing station, it drives the cutting piece 5 to move. The above two operating and moving methods are both common existing technologies in this field, and their specific structural principles will not be described in detail in this article.

[0027] like Figure 1 and Figure 2 As shown, a driving rod 7 is provided in the workbench 1, and a driving assembly for driving the turntable 2 to rotate intermittently is provided on the driving rod 7. The driving assembly includes a driving disk 8, a driving gear 9 and a driving member. A mounting plate 10 is fixed in the workbench 1, and the driving rod 7 is vertically penetrated on the mounting plate 10. The driving disk 8 is coaxial with the driving rod 7 and is fixedly sleeved on the driving rod 7. A mounting sleeve 11 is fixed on the mounting plate 10, and the driving gear 9 is rotatably arranged on the mounting sleeve 11. A connecting rod 12 is fixed at the axis of the driving gear 9. The connecting rod 12 is vertically upward and fixedly connected to the axis of the turntable 2. The driving member is arranged between the driving disk 8 and the driving gear 9, and the driving member includes a first connecting rod 13, a connecting block 14 and a second connecting rod 15. The first connecting rod 13 is rotatably arranged on the mounting plate 10, and a slide groove is provided on the driving disk 8. One end of the first connecting rod 13 is slidably arranged in the slide groove, as shown Figure 2As shown, the slide includes a semi-arc-shaped first slide 19, a semi-arc-shaped second slide 20 and two inclined grooves 21. The radius of the first slide 19 is smaller than the radius of the second slide 20. The two inclined grooves 21 are respectively connected to the ends of the first slide 19 and the second slide 20. The connecting block 14 is slidably inserted into the mounting sleeve 11. The end of the first connecting rod 13 away from the slide and the end of the connecting block 14 are hinged to the rod through a bearing. A mounting rod 16 is rotatably provided on the end of the first connecting rod 13 away from the slide. The end of the mounting rod 16 away from the first connecting rod 13 is fixed with a mounting block 17. One end of the second connecting rod 15 is hinged to the rod through a bearing and is arranged on the driving disk 8, and is not coaxial with the driving disk 8. Specifically, the end of the second connecting rod 15 is located between one end of the first connecting rod 13 on the driving plate and the axis of the driving disk 8. The end of the second connecting rod 15 away from the driving disk 8 is slidably inserted into the mounting block 17. Figure 2 and Figure 3 As shown, the mounting block 17 is provided with a mounting groove 28, and the side wall of the mounting groove 28 is provided with a groove 29. The second connecting rod 15 is provided with a protrusion 30, which is slidably arranged in the groove 29. The second connecting rod 15 is provided with a tooth segment 18 for engaging with the driving gear 9. The end of the connecting block 14 away from the first connecting rod 13 is fixed with a fixed tooth 22. When the driving disk 8 rotates, one end of the first connecting rod 13 slides in the sliding groove on the driving disk 8. When the end of the first connecting rod 13 slides from the first sliding groove 19 to the second sliding groove 20, the end of the first connecting rod 13 passes through one of the inclined grooves 21. At this time, the end of the first connecting rod 13 away from the driving disk 8 drives the connecting block 14 to slide in the mounting sleeve 11, and drives the mounting rod 16 and the mounting block 17 to move toward the driving gear 9. At the same time, the second connecting rod 15 slides on the mounting block 17, and the tooth segment 18 on the second connecting rod 15 engages with the driving gear 9. The continuous rotation of the driving disk 8 drives the second connecting rod 15 to The mounting block 17 slides back and forth in the mounting groove 28 on the mounting block 17, further driving the meshed drive gear 9 to rotate; when the end of the first connecting rod 13 slides from the second sliding groove 20 to the first sliding groove 19, the end of the first connecting rod 13 passes through another inclined groove 21. At this time, the end of the first connecting rod 13 away from the drive disk 8 drives the connecting block 14 to slide in the mounting sleeve 11, and drives the mounting rod 16 and the mounting block 17 to move away from the drive gear 9. At the same time, the tooth segment 18 on the second connecting rod 15 is separated from the drive gear 9, and the fixed tooth 22 at the end of the connecting block 14 is engaged with the drive gear 9 to prevent the drive gear 9 from rotating.

[0028] like Figure 2 、 Figure 4 and Figure 5As shown, the driving rod 7 is provided with a rotating part for driving the placement plate 4 to rotate during processing. The rotating part includes a rotating rod 23, a half gear 24, two pulleys 25 and a belt 26. A connecting gear 27 is fixed on each of the rotating shafts 3. One end of the rotating rod 23 is rotatably arranged on the mounting plate 10, and the other end is vertically upward and passes through the workbench 1. The half gear 24 is fixed to the end of the rotating rod 23 extending out of the workbench 1 and is used to engage with the connecting gear 27 on one of the rotating shafts 3. The two pulleys 25 are respectively fixedly mounted on the driving rod 7 and the rotating rod 23. The belt 26 is mounted on the two pulleys 25. The belt 26 is cross-wound and the two pulleys 25 rotate in opposite directions. The two pulleys 25 and the belt 26 effectively drive the rotating rod 23 to rotate when the driving rod 7 rotates. Furthermore, the half gear 24 at the end of the rotating rod 23 engages with the connecting gear 27 on the rotating shaft 3, driving the rotating shaft 3 to rotate, so that the sponge blank located on the rotating shaft 3 and the placement plate 4 is processed under the action of the cutting member 5. Specifically, when the tooth segment 18 is separated from the driving gear 9, the half gear 24 is in meshing with the connecting gear 27. When the tooth segment 18 is engaged with the driving gear 9, the half gear 24 is not meshing with the connecting gear 27. Several placement plates 4 are each provided with a plurality of fixing pins 32 for securing the sponge blank. Typically, each placement plate 4 is provided with two fixing pins 32. A protective cover 33 is provided on the outer wall of the workbench 1 and located on the turntable 2.

[0029] Working principle:

[0030] During operation, the drive rod 7 is first rotated as a power source. Specifically, this can be achieved by an external motor. Rotation of the drive rod 7 drives the drive disc 8, which is fixed to it, to rotate. A chute on the drive disc 8 guides one end of the first connecting rod 13 within it. As the end of the first connecting rod 13 slides along the chute 21 from the first chute 19 with a smaller radius to the second chute 20 with a larger radius, the first connecting rod 13 drives the connecting block 14 within the mounting sleeve 11 toward the drive gear 9. This movement, through the mounting rod 16, drives the mounting block 17 and the second connecting rod 15 slidingly inserted therethrough toward the drive gear 9, ultimately causing the tooth segments 18 on the second connecting rod 15 to mesh with the drive gear 9. Subsequently, the continued rotation of the drive disc 8 drives the second connecting rod 15 to reciprocate within the mounting slot 28 of the mounting block 17, thereby rotating the meshed drive gear 9. The rotation of the drive gear 9 is transmitted to the turntable 2 via the connecting rod 12 at its axis, causing the turntable 2 to rotate precisely to the angle corresponding to the position where the plate 4 is placed. After the rotation is completed, when the end of the first connecting rod 13 slides back from the second slide groove 20 to the first slide groove 19 along another inclined groove 21, the connecting block 14 is pulled back, driving the second connecting rod 15 away from the driving gear 9, causing its tooth segment 18 to separate from the driving gear 9. At the same time, the fixed teeth 22 at the end of the connecting block 14 engage with the driving gear 9, locking it firmly in the current position to prevent rotation during processing.

[0031] While the turntable 2 is locked in the processing position, two key actions occur simultaneously. First, the rotation of the drive rod 7, via two oppositely oriented pulleys 25 and belt 26, drives the rotating rod 23, which in turn rotates the half gear 24 at its tip. When one of the placement plates 4 on the turntable 2 rotates the sponge stock to the cutting position, the connecting gear 27 on the rotating shaft 3 engages with the rotating half gear 24. The half gear 24 drives the connecting gear 27, which in turn rotates the corresponding rotating shaft 3, the placement plate 4 bolted thereto, and the sponge stock. Second, the moving member 6 on the worktable 1 drives the cutting member 5 toward the rotating sponge stock. A pre-set electric cutting wire contacts the rotating sponge stock, cutting the sponge using the heat-melting principle to form the desired contour. The sponge stock is positioned by fixing pins 32 on the placement plate 4 to prevent it from shifting or falling out during processing.

[0032] When sponge cutting is complete at one station, the moving element 6 drives the cutting element 5 back to its original position. The drive disc 8 continues to rotate, unlocking the drive gear 9 and driving it via the second connecting rod 15, causing the turntable 2 to precisely rotate to the next station. The cut sponge is removed from the placement plate 4 and placed on the uncut sponge blank. Simultaneously, the half gear 24 at the top of the rotating rod 23 engages the connecting gear 27 on the new rotating shaft 3, which has moved to its meshing position, preparing to rotate the next sponge blank. The cutting element 5 advances again to make the cut. This cycle repeats, achieving continuous and efficient processing of special-shaped sponges at multiple stations.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
