Description

Technical Field

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

[0002] The shoe material vibrating knife cutting machine is an advanced CNC cutting device designed specifically for the shoe industry. It is used to efficiently and accurately cut various flexible shoe materials. Its core principle is to drive the blade to perform high-speed vertical reciprocating vibration to cut the material.

[0003] The CNC system controls the cutter head to move at high speed along a preset path, and the vibrating blade moves downward to complete the precise cut. During the cut, the vibration distance of the cutter must be at least greater than the thickness of the shoe material. When using a vibrating motor, although the amplitude can be adjusted, when the amplitude is adjusted to a large value, the vibration of the equipment will increase accordingly, affecting the cutting accuracy and causing significant deviations in the cutting dimensions. Summary of the Invention

[0004] To overcome the technical defects of the existing technology, the present invention provides a shoe material vibrating knife cutting machine and its cutting method, which reduces equipment vibration and increases dimensional accuracy.

[0005] The technical solution adopted in this invention is: A shoe material vibrating knife cutting machine includes a shoe material conveying system, a vibrating knife motion system, a shoe material side adjustment device, a frame, a finished product clamping system, a vibrating knife vibration system, and a dynamic range extender. The vibrating knife motion system is mounted on the frame, and a vibrating knife rod is mounted on the vibrating knife motion system. The dynamic range extender is mounted on the bottom of the vibrating knife rod. The shoe material conveying system is mounted on the frame, and the vibrating knife rod points towards the shoe material conveying system. The finished product clamping system is slidably mounted on the vibrating knife motion system, and the sliding direction of the finished product clamping system is perpendicular to the shoe material conveying system. The conveying direction of the feeding system is vertical. The dynamic range extender includes two side vibrating rods and a range extender blade. Each side vibrating rod is hinged to both sides of the vibrating blade rod. Each side vibrating rod is inclined and symmetrically arranged relative to the vibrating blade rod. Each side vibrating rod is mounted on the vibrating blade rod by a torsion spring. The range extender blade is slidably mounted on the bottom of the vibrating blade rod. The hinged position of the side vibrating rod engages with the side wall of the range extender blade. When the vibrating blade rod rises and falls, each side vibrating rod will drive the range extender blade to move. The direction of movement of the range extender blade relative to the vibrating blade rod is consistent with the direction of movement of the vibrating blade rod.

[0006] Preferably, the shoe material conveying system includes a shoe material conveying motor, a shoe material conveying roller, and a shoe material conveying belt. The shoe material conveying roller is rotatably mounted on the frame, the shoe material conveying motor is mounted on the frame, the shoe material conveying belt passes around the shoe material conveying roller, and the shoe material conveying motor is drivenly connected to the shoe material conveying roller.

[0007] Preferably, the vibrating knife motion system includes a vibrating knife lateral movement device, a vibrating knife longitudinal movement device, and a vibrating knife lifting device. The vibrating knife longitudinal movement device is mounted on the frame, the vibrating knife lateral movement device is slidably mounted on the vibrating knife longitudinal movement device, the vibrating knife lifting device is slidably mounted on the vibrating knife lateral movement device, and the vibrating knife vibration system is mounted on the vibrating knife lifting device.

[0008] Preferably, the shoe material side adjustment device includes a shoe material side adjustment cylinder and a shoe material side adjustment plate. The shoe material side adjustment cylinder is mounted on the frame, and the shoe material side adjustment plate is mounted on the output end of the shoe material side adjustment cylinder. The shoe material side adjustment plate is parallel to the conveying direction of the shoe material conveying system.

[0009] Preferably, the finished product clamping system includes a clamping longitudinal movement device, a clamping lifting device, a clamping rotary device, and a clamping suction cup device. The clamping longitudinal movement device is slidably mounted on the vibrating knife motion system. The clamping lifting device is mounted on the clamping longitudinal movement device. The clamping rotary device is mounted on the output end of the clamping lifting device. The clamping suction cup device is mounted on the bottom of the clamping rotary device.

[0010] Preferably, the angle between the side vibration rod and the vibrating knife rod is 45 degrees.

[0011] Preferably, the vibrating knife vibration system is a voice coil motor.

[0012] The cutting method of a shoe material vibrating knife cutting machine includes the following steps: S1: Footwear materials are conveyed on the footwear material conveying system; S2: The vibrating cutter motion system drives the vibrating cutter bar to move; S3: The vibrating knife vibration system drives the vibrating knife bar to rise and fall, and the side vibrating rod pushes the extended blade to vibrate longitudinally during the rising and falling of the vibrating knife bar.

[0013] The beneficial effects of this invention are: The vibrating knife motion system is mounted on the frame, the vibrating knife vibration system is mounted on the vibrating knife motion system, the vibrating knife vibration system is equipped with a vibrating knife rod, the dynamic range extender is mounted on the bottom of the vibrating knife rod, the shoe material conveying system is mounted on the frame to realize the conveying of shoe materials, the vibrating knife rod points towards the shoe material conveying system, and the finished product clamping system is slidably mounted on the vibrating knife motion system, the sliding direction of the finished product clamping system is perpendicular to the conveying direction of the shoe material conveying system.

Each rod is mounted on the rod via a torsion spring. The range extender blade is slidably mounted at the bottom of the rod. The hinged positions of the side vibrating rods engage with the side walls of the range extender blade. When the rod rises and falls, the side vibrating rods drive the range extender blade, and the direction of movement of the blade relative to the rod is the same as the direction of movement of the rod itself. That is, when the rod accelerates downwards, the side vibrating rods rotate upwards due to inertia, causing the range extender blade to accelerate downwards and automatically move further downwards. Conversely, when the rod accelerates upwards, the side vibrating rods rotate downwards due to inertia, causing the range extender blade to automatically move further upwards. This design reduces the vibration amplitude of the vibrating cutter system, lowers equipment vibration, and increases dimensional accuracy while ensuring sufficient stroke for the range extender blade.

Each side vibrating rod 71 is mounted on the vibrating cutter rod 61 via a torsion spring to counteract the weight of each side vibrating rod 71. The range extender blade 72 is slidably mounted on the bottom of the vibrating cutter rod 61 via a dovetail joint. The hinged position of the side vibrating rod 71 engages with the side wall of the range extender blade 72. When the vibrating cutter rod 61 rises and falls, each side vibrating rod 71 drives the range extender blade 72. The extended-stroke blade 72 moves relative to the vibrating cutter bar 61 in the same direction as the vibrating cutter bar 61 itself. That is, when the vibrating cutter bar 61 accelerates downward, the side vibrating rod 71 rotates upward under inertia, causing the extended-stroke blade 72 to accelerate downward. The extended-stroke blade 72 will automatically move further downward. When the vibrating cutter bar 61 accelerates upward, the side vibrating rod 71 rotates downward under inertia, and the extended-stroke blade 72 will automatically move further upward.
