DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Reference Figure 1-8 An embodiment of the present invention provides a CNC vibrating knife cutting machine, comprising a main body 1, on which a movable block 2, a bevel knife 3 and a reciprocating drive mechanism are arranged, the movable block 2 is rotatably connected to the main body 1; the bevel knife 3 is slidably arranged on the movable block 2; and the reciprocating drive mechanism is used to drive the bevel knife 3 to reciprocate on the movable block 2.

[0034] Specifically, the vibrating knife cutting machine is generally composed of a machine body, a moving mechanism, a vibrating mechanism, a cutting tool and a cutting table. When in use, the material to be cut (such as cartons, sound insulation cotton or cloth) is placed on the cutting table, and then the cutting tool is driven to vibrate by the vibrating mechanism. Then, the vibrating mechanism and the cutting tool are driven to move relative to the material on the cutting table by the moving mechanism to cut the material. This is a prior art and will not be described in detail here. For the straight knife, it is generally detachably connected to the vibrating mechanism so that the straight knife is driven to vibrate by the vibrating mechanism (driving the straight knife to vibrate along its own axis). For the oblique knife 3, its structure is the same as that of the straight knife, but the oblique knife 3 needs to adjust the angle according to the cutting situation to cut out an inclined surface (such as 30 degrees or 45 degrees), which makes the oblique knife 3 unable to adapt to the vibrating mechanism on the machine body. The innovation of the embodiment of the present invention lies in that the main body 1 is arranged on the above-mentioned fuselage, and the moving mechanism (such as a mechanical arm structure) on the fuselage can drive the main body 1 to move in plane and up and down on the cutting table. The movable block 2 is rotatably connected to the main body 1, and the bevel knife 3 is slidably connected to the movable block 2. In this embodiment, a reciprocating drive mechanism can be arranged on the movable block 2 to drive the bevel knife 3 to reciprocate on the movable block 2 (that is, to drive the bevel knife 3 to vibrate). The reciprocating drive mechanism can use the eccentric wheel vibration structure in the prior art. When in use, the angle of the bevel knife 3 can be adjusted by adjusting the angle between the movable block 2 and the main body 1. In this way, the reciprocating drive mechanism can drive the bevel knife 3 to vibrate at different angles and cut the material, thereby avoiding the situation of supporting the material during cutting as much as possible.

[0035] The CNC vibrating knife cutting machine provided in the embodiment of the present invention can adjust the angle of the bevel knife 3 by rotating the angle of the movable block 2. After the angle of the bevel knife 3 is determined, the reciprocating drive mechanism can drive the bevel knife 3 to reciprocate on the movable block 2, so that the bevel knife 3 can cut the material during vibration, and the situation of material support can be avoided as much as possible.

[0036] In another embodiment provided by the present invention, further, a slider 4 is slidably connected to the movable block 2, and the bevel knife 3 is limitedly connected to the slider 4. Specifically, a slide groove is constructed on the movable block 2, and the slider 4 is slidably connected in the slide groove. The reciprocating drive mechanism can be connected to the slider 4 or to the bevel knife 3, so as to drive the slider 4 and the bevel knife 3 to reciprocate synchronously along the slide groove through the reciprocating drive mechanism; the limited connection structure between the slider 4 and the bevel knife 3 can select a bolt connection structure or a clamping connection structure in the prior art, and such a setting can facilitate the replacement of the bevel knife 3.

[0037] Preferably, a connecting portion 5 is provided on the main body 1, and an arc groove 6 is constructed on the connecting portion 5, and the movable block 2 is slidably connected in the arc groove 6. Specifically, the movable block 2 can be directly connected to the main body 1 by a rotating shaft structure in the prior art to make the movable block 2 and the bevel knife 3 rotate around the rotating shaft, but in actual use, the tip of the tool is generally set at a specified position, such as the origin position, so that the tool can reciprocate close to or away from the origin position during the vibration process. Such a setting is convenient for setting or calculating the cutting trajectory and cutting range of the tool to improve the accuracy of the vibrating knife cutting machine; obviously, if a rotating shaft structure is selected, the rotating shaft needs to be set at the origin position, but the tool at the origin position needs to contact the material to cut the material, and for this reason, a connecting portion 5 and an arc groove 6 structure are set on the main body 1. The connecting portion 5 is constructed in an arc shape and is detachably connected to the main body 1 (such as a bolt connection structure). The arc groove 6 is constructed on one side of the connecting portion 5. The movable block 2 is constructed in an arc structure that is compatible with the arc groove 6. The center of the movable block 2 and the arc groove 6 structure is the above-mentioned origin position. When the bevel knife 3 is installed on the slider 4, if the slider 4 is at the end of the slide groove close to the origin position, the tip of the bevel knife 3 moves to the origin position; the advantage of such a setting is that when the slider 4 is at the end of the slide groove close to the origin position, no matter which position of the arc groove 6 the movable block 2 slides to, the tip of the bevel knife 3 is at the origin position, which limits the vibration range of the bevel knife 3, so that the bevel knife 3 can reciprocate close to or away from the origin position, thereby improving the accuracy of the bevel knife 3 in cutting the material.

[0038] Furthermore, a bolt hole 7 is constructed on the movable block 2, and a bolt 8 is threadedly connected to the inner thread of the bolt hole 7. Specifically, in the above embodiment, the position of the movable block 2 in the arc groove 6 can be adjusted by a linear drive structure, such as a cylinder whose two ends are respectively hinged to the connecting portion 5 and the movable block 2 (this is a prior art and will not be repeated here). Preferably, the bolt hole 7 is through-constructed on the movable block 2, the bolt 8 is threadedly connected in the bolt hole 7, the end of the bolt 8 is constructed as a rough surface and the end of the bolt 8 contacts the inner wall of the arc groove 6; when the bolt 8 is screwed out of the bolt hole 7, there is no restriction between the movable block 2 and the connecting part 5, so that the movable block 2 can slide along the arc groove 6 to adjust the angle of the bevel knife 3. After the angle of the bevel knife 3 is determined, the bolt 8 is screwed into the bolt hole 7 until the end of the bolt 8 contacts the inner wall of the arc groove 6. At this time, the friction between the movable block 2 and the arc groove 6 can be increased through the contact of the bolt 8 with the inner wall of the arc groove 6, so as to limit the relative position of the movable block 2 and the arc groove 6, and try to avoid the position of the movable block 2 from being offset after the angle of the bevel knife 3 is determined.

[0039] In another embodiment provided by the present invention, further, the reciprocating drive mechanism includes a transmission rod 9 slidably connected in the main body 1, and the transmission rod 9 is transmission-connected with the slider 4. Specifically, a vibration mechanism is provided on the main body 1 and the output end of the vibration mechanism is connected to the transmission rod 9. The vibration mechanism can select an eccentric shaft vibration structure in the prior art to drive the transmission rod 9 to reciprocate on the main body 1 through the vibration mechanism (the main body 1 in the prior art is provided with a vibration mechanism, and at this time, the straight knife can be directly connected to the end of the transmission rod 9 to drive the straight knife to vibrate. This is the prior art, not shown in the figure, and will not be repeated here); the transmission connection between the transmission rod 9 and the slider 4 can select a connecting rod transmission, so that when the transmission rod 9 reciprocates along the main body 1, the slider 4 is driven to reciprocate along the movable block 2, thereby driving the oblique knife 3 to vibrate; preferably, a connecting rod 10 is fixed on the transmission rod 9, and a connecting column 11 is provided on the slider 4, and a connecting groove 12 adapted to the connecting column 11 is constructed on the connecting rod 10. The connecting column 11 is slidably connected in the connecting groove 12, and the connecting column 11 can rotate in the connecting groove 12; the connection method between the connecting column 11 and the slider 4 can select the telescopic rod structure in the prior art to adjust the distance between the connecting column 11 and the slider 4; when the positions of the connecting column 11 and the slider 4 are relatively fixed, the transmission rod 9 can reciprocate along the main body 1 to drive the connecting rod 10 to move synchronously. When the connecting rod 10 reciprocates, it can contact the connecting column 11 through the inner wall of the connecting groove 12 and drive the slider 4 to reciprocate along the movable block 2 through the connecting column 11. During the process, the connecting column 11 will move relatively in the connecting groove 12 to adapt to the changes in the positions of the slider 4 and the connecting rod 10. The advantage is that when the device stops running, the transmission rod 9 and the connecting rod 10 are both at the bottom of their stroke. At this time, the position of the movable block 2 is first adjusted to determine the angle of the bevel knife 3. When adjusting the position of the movable block 2, the position of the connecting column 11 is also changed accordingly. In this way, the connecting column 11 and the slider 4 can be forced to move along the movable block 2 adaptively through the inner wall of the connecting groove 12 until the angle of the bevel knife 3 is determined. The relative position of the slider 4 and the connecting column 11 is adjusted to drive the tip of the bevel knife 3 to move to the origin position again. In this way, the transmission rod 9 at the bottom of the stroke and the bevel knife 3 with the tip at the origin position correspond to each other, so that the bevel knife 3 is driven to reciprocate close to or away from the origin position when the transmission rod 9 reciprocates in the subsequent process. The advantage is that in this embodiment, the reciprocating drive mechanism is arranged on the main body 1. When adjusting the angle of the bevel knife 3, the relative position of the slider 4 and the connecting column 11 can be adjusted adaptively, so that the reciprocating drive mechanism can maintain the drive of the bevel knife 3, so that the bevel knife 3 reciprocates close to or away from the origin position, and the application range of the device and the accuracy of cutting materials are improved as much as possible.

[0040] As an alternative to the above-mentioned adjustment of the relative position between the slider 4 and the connecting column 11 by the telescopic rod structure, further, the slider 4 is slidably connected with a slide rod 13, and one end of the slide rod 13 is fixed to the connecting column 11. Specifically, the slider 4 is constructed with an adapting groove adapted to the slide rod 13, the slide rod 13 is slidably connected in the adapting groove, and the end of the slide rod 13 away from the origin position is located outside the adapting groove and is fixed to the connecting column 11, the slider 4, the slide groove, the bevel knife 3, the slide rod 13 and the adapting groove are all arranged in the same direction (determined according to the position of the movable block 2 in the arc groove 6); when the transmission rod 9 is at the bottom of its stroke, the tip of the bevel knife 3 is at the origin position, and at this time, the angle of the bevel knife 3 can be adjusted by adjusting the position of the movable block 2 in the arc groove 6. During the adjustment process, the slide rod 13 slides along the adapting groove, and the connecting column 11 moves in the connecting groove 12. In this way, the angle of the bevel knife 3 can be adjusted when the tip of the bevel knife 3 is at the origin position; after the relative position between the slide rod 13 and the slider 4 is determined, the relative position of the slide rod 13 and the slider 4 can be fixed by the block structure in the prior art, so that the connecting column 11 and the slider 4, the bevel knife 3 and other structures are fixed together, and then when the transmission rod 9 moves back and forth, the slider 4 and the bevel knife 3 are driven to move synchronously along the movable block 2. Preferably, a brake pad 14 is elastically connected to the slider 4, and the side of the brake pad 14 away from the slider 4 is constructed as a smooth surface, and also includes an extrusion piece 15 for forcing the brake pad 14 to approach the slide rod 13. Elastic plates 16 are fixed at both ends of the brake pad 14, and the other ends of the two elastic plates 16 are fixed to the slider 4, such as Figure 6As shown, the brake pad 14 can be forced to move away from the slider 4 through two elastic sheets 16, and the slide bar 13 slightly protrudes from the adapting groove. A rubber pad is fixed to one end of the brake pad 14 close to the slide bar 13. The effect of such a setting is that when the extrusion member 15 squeezes the brake pad 14 to force the brake pad 14 close to the slide bar 13, the elastic sheet 16 deforms and stores elastic potential energy. At the same time, the rubber pad on the brake pad 14 can squeeze the slide bar 13 and the outer wall of the slider 4 to fix the relative position of the slider 4 and the slide bar 13. At this time, the brake pad 14 and the extrusion member 15 are in a state of being ... The friction between the brake pad 14 and the extrusion piece 15 is small (because the side of the brake pad 14 close to the extrusion piece 15 is constructed as a smooth surface), and the two can move relative to each other, that is, the extrusion piece 15 keeps squeezing the brake pad 14 to fix the relative position of the slider 4 and the slide bar 13, and in the process, the extrusion piece 15 can move relative to the slider 4; the length of the brake pad 14 is greater than the length of the extrusion piece 15, and in the process of relative movement of the extrusion piece 15 and the brake pad 14, the extrusion piece 15 can keep squeezing the brake pad 14 to limit the relative position of the slide bar 13 and the slider 4. The advantage is that the extrusion piece 15 can be set on the movable block 2 to squeeze the brake pad 14 after the angle of the bevel knife 3 is determined, thereby limiting the relative position of the exchange and the slider 4. Preferably, in order to further reduce the friction between the extrusion piece 15 and the brake pad 14, a plurality of rollers 17 are rotatably connected to the side of the extrusion piece 15 close to the brake pad 14. While the brake pad 14 is squeezed by the rollers 17, the brake pad 14 can also drive the rotating shaft to rotate as the slider 4 moves, so as to reduce the friction between the two while maintaining the squeezing force of the extrusion piece 15 on the brake pad 14.

[0041] It should be noted that the travel of the transmission rod 9 and the connecting rod 10 is certain, and the thickness of the material is also certain. When the angle of the inclined knife 3 and the slide bar 13 is adjusted, the travel of the connecting rod 10 driving the connecting column 11 and the slide bar 13 to move will also change accordingly. Figure 3 As shown, the angle is small, and the contact area between the bevel knife 3 and the material is also small. At this time, the amplitude of vibration of the bevel knife 3 driven by the connecting rod 10 is also small; when the movable block 2 slides to the left along the arc groove 6, the inclination angle of the bevel knife 3 becomes larger, and the contact area between the bevel knife 3 and the material is also larger. At this time, the amplitude of vibration of the bevel knife 3 driven by the connecting rod 10 is also increased accordingly, so that the vibration amplitude of the bevel knife 3 can be adaptively adjusted to adapt to different cutting conditions.

[0042] Furthermore, a mounting groove 19 is formed at one end of the bolt hole 7 away from the arc-shaped groove 6 , and a mounting block 18 adapted to the mounting groove 19 is fixed on the extrusion member 15 . Specifically, the mounting groove 19 is connected to the bolt hole 7, and the cross-sections of the mounting groove 19 and the mounting block 18 are both constructed as polygons, so that after the mounting block 18 is inserted into the mounting groove 19, the position of the extrusion piece 15 can correspond to the brake pad 14 to extrude the brake pad 14, thereby fixing the relative positions of the slide bar 13 and the slider 4; a through hole is constructed on the mounting block 18, and the bolt 8 is inserted into the through hole and threadedly connected in the bolt hole 7, so that the mounting block 18 can be restricted in the mounting groove 19 when the bolt 8 is screwed into the bolt hole 7, thereby restricting the position of the extrusion piece 15; the advantage is that when the bolt 8 is screwed out of the bolt hole 7, the movable block 2 loses the restriction of the bolt 8 and can move in the arc groove 6, and at the same time, the extrusion piece 15 also loses the restriction of the bolt 8 and can move out of the mounting groove 19, thereby simultaneously releasing the restriction between the movable block 2 and the connecting portion 5 and the restriction between the slide bar 13 and the slider 4, so that when the movable block 2 moves along the arc groove 6, the slide bar 13 can slide relative to the slider 4, thereby adapting to the change in the position of the connecting column 11 in the connecting groove 12.

[0043] In another embodiment provided by the present invention, further, a limiting mechanism is included for limiting the relative position of the slider 4 and the movable block 2. Specifically, the limiting mechanism can select the electric clamping block structure in the prior art to limit the relative position of the slider 4 and the movable block 2 when the limiting mechanism is running; in the above embodiment, when the bolt 8 is removed from the bolt hole 7, the restriction between the movable block 2 and the connecting portion 5 and the restriction between the slide rod 13 and the slider 4 are released synchronously, so that when the movable block 2 moves along the arc groove 6, the connecting column 11 can adapt to move in the connecting groove 12, but in this process, the position between the slider 4 and the movable block 2 may be offset, which will cause the position of the tip of the bevel knife 3 to be offset from the origin. The position is moved away, thereby changing the vibration range of the bevel knife 3. For this purpose, a limiting mechanism is provided. When the transmission rod 9 is at the bottom of its stroke, the tip of the bevel knife 3 is at the origin position. At this time, after the bolt 8 is removed from the bolt hole 7, the relative position of the slider 4 and the movable block 2 can be limited by the limiting mechanism, and the tip of the bevel knife 3 can be prevented from being separated from the origin position as much as possible; the advantage is that by providing a limiting mechanism, when the bolt 8 is screwed into the bolt hole 7, the relative position of the movable block 2 and the connecting part 5 can be limited by the end of the bolt 8, and at the same time, the brake pad 14 can be pressed by the extrusion piece 15 The sliding rod 13 is pressed to limit the relative position of the sliding block 4. During this process, the limiting mechanism operates synchronously to release the relative position limit of the sliding block 4 and the movable block 2, so that the movable block 2 is fixed on the connecting portion 5, and the sliding rod 13 is fixed on the sliding block 4. Then, the reciprocating motion of the connecting rod 10 drives the sliding rod 13, the sliding block 4 and the bevel knife 3 to reciprocate, so that the material is cut by the bevel knife 3; on the contrary, when the device stops running, the connecting rod 10 is at the bottom of its stroke, and the tip of the bevel knife 3 stays at the origin. At this time, the bolt 8 is screwed out of the bolt hole. 7 can release the restriction on the movable block 2, and at the same time release the restriction on the relative position of the slide bar 13 and the slider 4. During this process, the limiting mechanism operates synchronously to limit the relative position of the slider 4 and the movable block 2, so that the angles of the movable block 2, the slider 4 and the bevel knife 3 can be adjusted when the tip of the bevel knife 3 is at the origin position, and when adjusting the angle, the connecting column 11 can adaptably move in the connecting groove 12, and the slide bar 13 can also adaptably slide on the slider 4. After the angle is determined, the bolt 8 can be screwed in again to make the device run again to cut the material.

[0044] Preferably, the limiting mechanism includes a movable groove constructed on the movable block 2, in which a buckle 20 is rotatably connected, and a torsion spring is provided in the movable groove for forcing the buckle 20 to contact the slider 4. The movable groove is connected to the bolt hole 7, and the buckle 20 extends into the bolt hole 7. Specifically, the slide groove and the bolt hole 7 are connected through a movable groove, and the middle part of the buckle 20 is rotatably connected to the inner wall of the movable groove. The end of the buckle 20 close to the slide groove is the braking end, and the end close to the bolt hole 7 is the contact end. In the process of the slider 4 sliding along the slide groove, the buckle 20 can be forced to rotate through the torsion spring so that the braking end contacts the slider 4. The side of the braking end close to the slider 4 is constructed as a rough surface (a toothed structure or a rubber structure can be provided at the corresponding position between the braking end and the slider 4) to limit the relative position of the slider 4 and the connecting part 5 when the braking end contacts the slider 4. When the bolt 8 is screwed into the bolt hole 7, the contact end can be contacted by the end head and outer wall of the bolt 8, thereby forcing the buckle 20 to rotate to drive the braking end away from the slider 4, so that the relative position limit between the slider 4 and the connecting part 5 can be released when the bolt 8 is screwed into the bolt hole 7. In this embodiment, when the device stops running, the connecting rod 10 stays at the bottom of its stroke, and accordingly, the tip of the bevel knife 3 stays at the origin position. At this time, the angle of the bevel knife 3 can be adjusted by simply screwing the bolt 8 out of the bolt hole 7. When the bolt 8 is screwed out of the bolt hole 7, the restriction between the movable block 2 and the connecting portion 5 is released, the restriction between the slide rod 13 and the slider 4 is released, and the relative position between the slider 4 and the connecting portion 5 is restricted by the buckle 20, so that when the movable block 2 moves along the arc groove 6 to adjust the angle of the bevel knife 3, the relative position of the slider 4 and the movable block 2 remains unchanged (that is, the tip of the bevel knife 3 remains at the origin position). ), the connecting column 11 adapts to move in the connecting groove 12, and the sliding rod 13 adapts to slide on the slider 4 until the angle of the bevel knife 3 is determined, and then the bolt 8 is screwed into the bolt hole 7 again, so as to limit the relative position of the movable block 2 and the connecting part 5. At the same time, the relative position of the sliding rod 13 and the slider 4 can be limited by the extrusion piece 15 (the extrusion piece 15 does not affect the relative displacement between the slider 4 and the movable block 2), and the relative position between the slider 4 and the connecting part 5 can be released by the bolt 8 contacting the buckle 20, so that the bevel knife 3 can reciprocate on the movable block 2 through the slider 4, and then cut the material.

[0045] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
