DETAILED DESCRIPTION

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The present application embodiment discloses a material cutting machine for shoe production, referring to Figure 1 , Figure 2 and Figure 3 , including a cutting platform 1, a first mounting frame 2 is installed on the cutting platform 1 in a horizontal linear driving manner, the two ends of the first mounting frame 2 are mounted on both sides of the cutting platform 1, and a track is fixedly installed on the first mounting frame 2 horizontally and perpendicularly to the sliding direction of the first mounting frame 2. The first mounting frame 2 is driven by a motor on the first mounting frame 2 to rotate the gear and cooperate with the rack on the cutting platform 1, so that the first mounting frame 2 moves parallel to the cutting platform 1. A first moving seat 3 is slidably installed on the track on the first mounting frame 2, and a linear screw module is arranged in the first mounting frame 2 to drive the first moving seat 3 to slide linearly relative to the first mounting frame 2.

[0024] A rotating frame 4 is relatively rotatably mounted at the bottom end of the first movable seat 3, the rotating shaft of the rotating frame 4 is vertical, a second movable seat 5 is radially slidably mounted on the rotating frame 4 along its own rotating shaft, and a vibrating cutter head 6 is mounted at the bottom of the second movable seat 5. A downward pressing fixing piece is disposed on the first movable seat 3 at the outer side of the rotating frame 4. A first driving assembly for driving the rotating frame 4 to rotate is disposed on the first movable seat 3, a second driving assembly for driving the second movable seat 5 to rotate is disposed on the rotating frame 4, and a third driving assembly for driving the downward pressing fixing piece to vertically rise and fall is disposed on the first movable seat 3.

[0025] When cutting the cloth on the cutting platform 1, the rotating frame 4 is driven to rotate, and the second movable seat 5 on the rotating frame 4 moves back and forth, so that the vibrating cutter head 6 moves and cuts the required shape on the cloth. While cutting the cloth, the pressing and fixing components on both sides of the rotating frame 4 press the cloth on both sides of the rotating frame 4, avoiding the situation where the cloth that has been cut on the outside of the rotating frame 4 pops up and causes wrong cutting.

[0026] Specifically, a connecting sleeve 41 is vertically fixedly connected to the top wall at one end of the rotating frame 4, and the top end of the connecting sleeve 41 is relatively rotatably connected to the first movable seat 3. The first driving assembly includes a first driving motor 31, and the first driving motor 31 is fixedly arranged on the first movable seat 3. A gear ring is coaxially fixed on the outer wall of the connecting sleeve 41, and a gear is connected to the output shaft of the first driving motor 31. The gear on the first driving motor 31 is meshed with the gear ring on the connecting sleeve 41, and the first driving motor 31 is used to drive the connecting sleeve 41 to rotate.

[0027] The second driving assembly includes a second driving motor 44, a transmission screw 42 is rotatably arranged in the rotating frame 4, the transmission screw 42 passes through the second moving seat 5 and is threadedly connected to the second moving seat 5, a transmission rod 43 is coaxially connected in the connecting sleeve 41, and the second driving motor 44 is fixedly connected to the top of the connecting sleeve 41. The second driving motor 44 is used to drive the transmission rod 43 to rotate, and the transmission rod 43 and the transmission screw 42 are meshed and driven by bevel gears. When the second driving motor 44 is running, it drives the transmission rod 43 to rotate, and the transmission rod 43 drives the transmission screw 42 to rotate. The transmission screw 42 is threadedly matched with the second moving seat 5 during the forward and reverse rotation process, so that the second moving seat 5 can move back and forth linearly on the rotating frame 4.

[0028] The pressing fixture includes a second mounting frame 71 arranged on both sides of the rotating frame 4 along the moving direction of the first moving seat 3, and two mutually parallel transmission rollers 72 are arranged on the second mounting frame 71 to rotate at intervals along the length direction of the second mounting frame 71, and a belt 73 is sleeved on the two transmission rollers 72. Since the belt 73 and the transmission roller 72 are not driven by power, when the first moving seat 3 moves linearly, the pressing fixture keeps the cloth pressed on the cutting platform 1, and the belt 73 moves on the cloth through the friction between the belt 73 and the cloth, and the insole after cutting is pressed in time. Furthermore, anti-skid patterns can be set on the surface of the belt 73 to increase the friction of the belt 73 when it moves on the cloth, so as to avoid the belt 73 rubbing against the cloth.
