Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, and in particular to a shoe material cutting machine and its cutting method that produces regular cuts. Background Technology

[0002] A vibrating blade cutting machine, also known as a vibrating shearing machine, is a CNC device that uses high-frequency mechanical vibration for cutting. Its core working principle is as follows: the machine uses an internal vibrating motor and eccentric shaft-linkage mechanism to drive the upper cutting blade to reciprocate rapidly at a high frequency of thousands of times per minute. During cutting, the high-speed vibrating blade contacts the material, instantly generating and concentrating a huge shearing force, thereby cutting the material.

[0003] The main advantage of this technology is that it is "non-thermal cutting." Unlike lasers or hot knives, it does not generate high heat during the cutting process, thus effectively avoiding scorching, deformation, or unpleasant odors, making it particularly suitable for heat-sensitive materials. At the same time, it has broad material adaptability, capable of precisely cutting a variety of materials from soft leather, textiles, and composites to rigid materials such as KT board, EPE foam, and rubber.

[0037] The present invention will be further described below with reference to the accompanying drawings:

[0038] like Figure 1 — Figure 6 As shown, this embodiment provides a shoe material cutting machine with regular cuts, including a shoe material conveying device, a cutting motion device 1, a cutting traverse device 2, a frame 4, a cutting lifting device 3, a cutting vibration device 5, a cutting rotation device 6, and a vibration strengthening device 7.

The cutting motion device 1 is slidably installed on the frame 4, and the movement direction of the cutting motion device 1 is parallel to the conveying direction of the shoe material conveying device, driving the cutting traverse device 2 to move. The cutting traverse device 2 is slidably installed on the cutting motion device 1, and the cutting traverse device 2 moves.

The cutting lifting device 3 is mounted on the cutting transverse device 2 to realize the lifting of the cutting vibration device 5. The cutting vibration device 5 is mounted on the cutting lifting device 3. A vibration strengthening device 7 is installed on the lower side of the cutting vibration device 5. A cutting blade 8 is installed on the lower side of the vibration strengthening device 7. The cutting rotation device 6 is rotatably mounted on the cutting vibration device 5. The cutting blade 8 passes through the cutting rotation device 6. The rotation of the cutting rotation device 6 drives the cutting blade 8 to realize the rotation of the cutting blade 8.

[0039] Specifically, the vibration enhancement device 7 includes a vibration enhancement motor 71, an upper vibration ratchet 72, a lower vibration ratchet 73, and a return spring 75. The cutting blade 8 is mounted on the lower side of the lower vibration ratchet 73. The cutting vibration device 5 is provided with a rotating hole 531 for the cutting blade 8 to pass through. There is a gap of 0.2 mm to 1 mm between the rotating hole 531 and the cutting blade 8, thereby constraining the position of the cutting blade 8 and the lower vibration ratchet 73. The lower side of the return spring 75 presses on the cutting vibration device 5, and the lower vibration ratchet 73 presses on the upper side of the return spring 75. The vibration enhancement motor 71 is mounted on the cutting vibration device 5, and the upper vibration ratchet 72 is mounted on the output end of the vibration enhancement motor 71. The upper side of the lower vibration ratchet 73 is adapted to the lower side of the upper vibration ratchet 72. When the vibration enhancement motor 71 rotates, it causes the upper vibration ratchet 72 to rotate. The upper vibration ratchet 72 pushes the lower vibration ratchet 73 intermittently downward, enhancing the vibration frequency of the cutting blade 8.

[0040] Specifically, the shoe material conveying device includes a shoe material conveying motor and a shoe material conveying belt. The shoe material conveying motor is installed on the frame 4, and the shoe material conveying belt is installed on the frame 4. The shoe material conveying motor and the shoe material conveying belt are connected in a drive connection to realize the conveying of shoe material raw materials.

[0041] Specifically, the cutting motion device 1 includes a cutting motion beam 11, a cutting motion motor 12, and a cutting motion rack 13. The cutting motion rack 13 is mounted on the frame 4, and the cutting motion motor 12 is mounted on the cutting motion beam 11. The cutting motion motor 12 is connected to the cutting motion rack 13 through a gear set. The cutting motion beam 11 slides along the frame 4, and the cutting transverse movement device 2 is slidably mounted on the cutting motion device 1. The cutting motion device 1 drives the cutting transverse movement device 2 to move.

[0042] Specifically, the cutting transverse movement device 2 includes a cutting transverse movement slider 21, a cutting transverse movement motor 22, and a cutting transverse movement rack 23. The cutting transverse movement rack 23 is mounted on the cutting motion device 1, and the cutting transverse movement motor 22 is mounted on the cutting transverse movement slider 21. The cutting transverse movement motor 22 is connected to the cutting transverse movement rack 23 through a gear set. The cutting transverse movement slider 21 slides along the cutting motion device 1, and the cutting lifting device 3 is slidably mounted on the cutting transverse movement device 2 in the lifting direction. The cutting transverse movement device 2 drives the cutting lifting device 3 to move transversely.

[0043] Specifically, the cutting lifting device 3 includes a cutting lifting frame 31, a cutting lifting slider 32, a cutting lifting motor 33, and a cutting lifting screw. The cutting lifting frame 31 is mounted on the cutting transverse device 2, the cutting lifting slider 32 is slidably mounted on the cutting lifting frame 31, the cutting lifting motor 33 is mounted on the cutting transverse device 2, and the cutting lifting screw is mounted on the output end of the cutting lifting motor 33. The cutting lifting screw and the cutting lifting slider 32 are connected by a threaded pair. The cutting vibration device 5 is mounted on the cutting lifting slider 32 to realize the lifting and lowering of the cutting vibration device 5 and adjust the height of the cutting blade 8 so that it is close to the shoe material fabric.

[0044] Specifically, the cutting vibration device 5 includes a cutting vibration motor 51, a cutting vibration cam 52, and a cutting vibration slider 53. The cutting vibration cam 52 is installed on the output end of the cutting vibration motor 51. The cutting vibration slider 53 is connected to the cutting lifting slider 32 of the cutting lifting device 3 through a sliding pair. The cutting vibration motor 51 is installed on the cutting lifting slider 32. The cutting vibration cam 52 and the cutting vibration slider 53 are hinged together by a connecting rod 55. The vibration strengthening motor 71, the upper vibration ratchet 72, the lower vibration ratchet 73, and the return spring 75 mentioned above are all installed on the cutting vibration slider 53. The rotation of the cutting vibration cam 52 realizes the vibration of the cutting blade 8.

[0045] Specifically, the cutting rotation device 6 includes a cutting rotary table 61 and a cutting rotary motor 62. The cutting rotary table 61 is rotatably mounted on the cutting transverse device 2 via bearings. The cutting rotary table 61 is provided with a rotation control slot 611 for the cutting blade 8 to pass through. The cutting rotary motor 62 is mounted on the cutting transverse device 2 and is connected to the cutting rotary table 61 for transmission, thereby realizing the rotation of the cutting blade 8.

[0046] When the vibration enhancement motor 71 rotates, the upper vibration ratchet 72 and the lower vibration ratchet 73 of the cutting blade 8 move relative to each other under the constraint of the rotation control slot 611. The upper vibration ratchet 72 pushes the lower vibration ratchet 73 intermittently downward. Since the upper vibration ratchet 72 and the lower vibration ratchet 73 are always in relative rotation, the upper vibration ratchet 72 will not jam the lower vibration ratchet 73 regardless of whether the rotation control slot 611 rotates forward or backward. The lower vibration ratchet 73 is reset under the elastic force of the return spring 75, realizing the vibration of the cutting blade 8. On the other hand, the cutting vibration cam 52 drives the cutting vibration slider 53 to vibrate up and down. The two vibrations are superimposed. The cutting vibration cam 52 provides a large amplitude and low frequency vibration, while the upper vibration ratchet 72 provides a small amplitude and high frequency vibration, ensuring the cutting effect of the cutting blade 8.
