[0025] The present invention will be described in detail below with reference to the accompanying drawings:

[0026] Embodiment 1

[0027] The cutting device of this embodiment includes: a cutting part 1, as Figure 1 shown, the cutting part 1 includes a cross - knife mechanism 2, and the cross - knife mechanism 2 includes: a main beam 4, the main beam 4 has two ends, namely a first end 5 and a second end 6. The first end 5 of the main beam 4 is movably arranged along the direction of material travel or the opposite direction of material travel, and the second end 6 of the main beam 4 is movably arranged along the direction of material travel or the opposite direction of material travel; a feeding mechanism, and the feeding mechanism is spaced from the cutting part 1.

[0028] A first driving device 7 is arranged at the first end 5 of the main beam 4. The first driving device 7 drives the first end 5 to move along the direction of material travel or the opposite direction of material travel, or the first driving device 7 drives through a first transmission mechanism to move along the direction of material travel or the opposite direction of material travel; a second driving device 8 is arranged at the second end 6 of the main beam 4. The second driving device 8 drives the second end 6 to move along the direction of material travel or the opposite direction of material travel, or the second driving device 8 drives through a second transmission mechanism to move the second end 6 along the direction of material travel or the opposite direction of material travel.

[0029] The described first transmission mechanism includes a first lead screw 9 and a first slider 10. The first slider 10 is slidably arranged along the first lead screw 9. The first end 5 of the main beam 4 is rotatably connected to the first slider 10. The second transmission mechanism includes a second lead screw 11 and a second slider 12. The second slider 12 is slidably arranged along the second lead screw 11. The cutting part 1 further includes a third slider 13 and a compensation guide rail 14. The third slider 13 is slidably arranged along the compensation guide rail 14. The compensation guide rail 14 is arranged at the bottom of the second end 6 of the main beam 4. The third slider 13 is arranged above the second slider 12. The third slider 13 is rotatably connected to the second slider 12. The rotatable connection between the first end 5 of the main beam 4 and the first slider 10 and the rotatable connection between the third slider 13 and the second slider 12 can both be realized by arranging a rotating bearing 31.

[0030] A first guide rail 15 is provided at the bottom of the first slider 10. The first guide rail 15 guides the first slider 10 to slide along the first lead screw 9. A second guide rail 16 is provided at the bottom of the second slider 12. The second guide rail 16 guides the second slider 12 to slide along the second lead screw 11.

[0031] This embodiment further includes a tool rest 17 and a cutting tool 18. The tool rest 17 is arranged on the main beam 4. The tool rest 17 is slidably arranged along the axial direction of the main beam 4. In this embodiment, the tool rest 17 is driven by a driving motor 30 to move along the axial direction of the main beam 4.

[0032] The cutting tool 18 is arranged on the tool rest 17. The position of the cutting tool 18 is adjustably arranged along the axial direction of the tool rest 17. The cutting tool 18 is arranged on the tool rest 17 by a fixing member 19. A slotted hole 20 is provided on the fixing member 19. By adjusting the fixing position of the slotted hole 20, the position of the cutting tool 18 can be adjusted along the axial direction of the tool rest 17. The axial direction of the tool rest 17 is the direction perpendicular to the ground.

[0033] This embodiment further includes a first image recognition device 21 and a second image recognition device 22. The first image recognition device 21 and the second image recognition device 22 are respectively arranged on the top of the main beam 4. The first image recognition device 21 and the second image recognition device 22 are respectively slidably arranged along the axial direction of the main beam 4.

[0034] When the transverse mechanism cuts the material, it generally makes a transverse cut perpendicular to the advancing direction of the material. However, sometimes the material may deviate. The head edge of the material is inclined at a certain angle with the horizontal direction, which will cause the transverse cut not to be parallel to the head edge of the material, that is, the cut material is no longer in a horizontal and vertical shape. At this time, in order for the transverse cut to still be parallel to the head edge of the material, or perpendicular to the side of the material, it is necessary to adjust the cutting direction of the cutting tool 18.

[0035] The first image recognition device 21 and the second image recognition device 22 detect both ends of the cutting mark on the material. The cutting mark is inclined. The first image recognition device 21 and the second image recognition device 22 recognize that the positions of the two ends moving forward are inconsistent, and then transmit the information to the controller. The controller controls the first driving device 7 and the second driving device 8 to make adjustments according to the signal. Both ends of the main beam 4 move forward or backward in the direction of material movement for adjustment. The first end 5 of the main beam 4 rotates relative to the first slider 10, and the third slider 13 rotates relative to the second slider 12. Both ends of the main beam 4 are no longer horizontal, but are at the same inclination angle as the cutting mark of the material, so that the cutting knife 18 can cut out a cutting edge that is horizontal with the edge of the head of the material. Here, due to the inclination of the main beam 4, compared with the length side when it is horizontal, the third slider 13 slides along the compensation guide rail 14, which can provide displacement compensation after the rotation of the main beam 4. In this way, regardless of whether the material is offset, the cutting knife 18 can be adjusted along the actual movement direction of the material, so that the cutting direction of the cutting knife 18 is perpendicular to the actual movement direction of the material, thus ensuring the flatness of the cutting. The controller can be a computer, an industrial control computer or a PLC.

[0036] As Figure 2 shown, the feeding mechanism includes a support positioning member 23. The support positioning member 23 is arranged at an interval from the cutting part 1, and the support positioning member 23 is rotatably arranged; both ends of the support positioning member 23 are rotatably arranged respectively.

[0037] This embodiment further includes a frame 24 and a horizontal bracket 25. The horizontal bracket 25 is arranged on the frame 24. The frame 24 supports the cutting part 1. The support positioning member 23 includes an air shaft. The feeding mechanism includes a tension roller 26. The air shaft and the tension roller 26 are arranged on the horizontal bracket 25 at intervals; the air shaft is arranged at an interval from the cutting part 1. Two support rods 33 are arranged on the horizontal bracket 25. Each support rod 33 is respectively provided with a vertically arranged U-shaped groove 34 for supporting both ends of the air shaft. The opening of the vertically arranged U-shaped groove 34 faces upward. Both ends of the air shaft are rotatably arranged on the vertically arranged U-shaped groove 34.

[0038] The tension roller 26 is arranged at an interval from the cutting part 1. The air shaft, the tension roller 26 and the cutting part 1 are arranged in sequence. When the material is fed, it passes through the air shaft and the tension roller 26 in sequence, and then enters the cutting part 1. The material is wound on the air shaft. When feeding, a layer of material is pulled out from the direction of the air shaft, bypasses the tension roller 26, and enters the cutting part 1.

[0039] The cutting part 1 includes a longitudinal knife mechanism 3 and a transverse knife mechanism 2. The cutting direction of the longitudinal knife mechanism 3 is parallel to the movement direction of the material. In this embodiment, the longitudinal knife mechanism 3 can be a conventional mechanism.

[0040] The material is set on the unexpanded air shaft in a rolled-up manner. After the feeding is completed, the air shaft expands and tightens the rolled-up material, and the axial position of the rolled-up material on the air shaft will not shift. This achieves a good positioning effect on the material. Moreover, due to the tensioning effect of the air shaft, the material is more tightly wound during the rolled-up feeding, which is beneficial to the cutting of the material.

[0041] Embodiment 2

[0042] As Figure 3 shown, this embodiment further includes a third driving device 27. The third driving device 27 drives the first image recognition device 21 and the second image recognition device 22 to be arranged to move axially along the main beam 4, or the third driving device 27 drives the first image recognition device 21 and the second image recognition device 22 to move axially along the main beam 4 through a third transmission mechanism.

[0043] The third transmission mechanism includes a third lead screw 28. The first image recognition device 21 and the second image recognition device 22 are arranged on a sliding groove 29, and the first image recognition device 21 and the second image recognition device 22 can slide in the sliding groove 29 respectively. The third lead screw 28 is connected to the sliding groove 29, and the third lead screw 28 can drive the sliding groove 29 to move along the axis of the main beam 4. A guiding mechanism of a slider and a guide rail is provided at the bottom of the sliding groove 29.

[0044] In this embodiment, the first image recognition device 21 and the second image recognition device 22 can automatically adjust their positions, so that the recognition range can be increased.

[0045] Embodiment 3

[0046] As Figure 4 and Figure 5 shown, this embodiment further includes a frame 24. The frame 24 supports the cutting part 1. The supporting and positioning member 23 includes an air shaft. Slightly different from Embodiment 1, the air shaft is arranged at the lower part of the frame 24, that is, below the frame 24 and below the cutting part 1. The two ends of the air shaft are respectively rotatably arranged on the frame 24, that is, the air shaft is arranged to be rotatable by itself. This embodiment provides a feeding method different from that of Embodiment 1 to adapt to materials of different specifications. The material enters the cutting part 1 from the air shaft.

[0047] One end of the supporting and positioning member 23 described in this embodiment is arranged to be movable radially, and the other end of the supporting and positioning member 23 is arranged to be rotatable radially. The supporting and positioning member 23 is an air shaft.

[0048] A support bearing is provided at one end of the described frame 24 on the support positioning member 23, and a support seat is provided at the other end of the support positioning member 23. A horizontal U-shaped groove 32 is provided on the support seat; one end of the support positioning member 23 is arranged on a universal bearing, and the other end is arranged in the horizontal U-shaped groove 32. That is, one end of the air shaft is provided with a universal bearing, and the other end is arranged in a horizontal U-shaped groove 32. The opening of the horizontal U-shaped groove 32 faces away from the frame 24. When feeding the material, one end of the air shaft is radially moved out of the horizontal U-shaped groove 32 of the support seat, and the material can be fed. After the feeding is completed, this end of the air shaft is moved into the horizontal U-shaped groove 32 of the support seat.

[0049] A blocking member is provided at the radially rotatable end of the described support positioning member 23, and the blocking member can block the radial rotation of the support positioning member 23. There are multiple blocking members, which are respectively arranged around the support bearing and are located outside the axial direction of the support positioning member 23. In this embodiment, the support positioning member 23, that is, the universal bearing of the air shaft, is arranged in a support frame 40. One side of the support frame 40 protrudes to form a first blocking member 44. The other blocking members are all rods 41, 42, 43 arranged on the first blocking member 44. The first blocking member 44 and the rods 41, 42, 43 are connected to each other in pairs to form a frame. When this end of the air shaft rotates radially, if it rotates within a reasonable range, it will not touch the blocking member. If it rotates beyond the set reasonable range, it will touch the blocking member. In this way, the blocking member can prevent the radial over-rotation of the air shaft.

[0050] The present invention can realize the adjustment of the transverse cutting of the material according to the actual feeding direction. Moreover, the feeding mechanism of the present invention can realize the positioning of the material feeding, prevent the deviation of the material, and control the cutting quality better. After the material is wound and fed, it is more compact, which can also improve the cutting quality.

[0051] The embodiments in the present invention are only used to illustrate the present invention and do not constitute a limitation on the scope of the claims. Other substantially equivalent alternatives that can be conceived by those skilled in the art are all within the protection scope of the present invention.
