[0024] In this paper-plastic cutting machine, the paper-plastic piece to be cut is placed on the jig plate 11, and the first suction cup 31 in the first transfer mechanism 3 moves to the jig plate 11, and the paper-plastic piece located at the top is sucked out and transferred to the cutting mold 22, and then returns to reset, and the jig plate 11 moves up to prepare for the next loading of paper-plastic pieces, and the main force-applying part is transmitted to the middle of the cutting plate 23, and the sub-force-applying part is transmitted to the side of the cutting plate 23, driving the cutting plate 23 to move down to the cutting mold 22, and the paper-plastic piece is cut. After the processing is completed, the main force-applying part and the sub-force-applying part drive the cutting plate 23 to move upward, and the second suction cup 41 in the second transfer mechanism 4 moves to the cutting mold 22 to absorb the processed paper-plastic parts and transfer them out of the cutting mold 22. In this way, the paper-plastic parts can be automatically loaded, cut and unloaded, which reduces manual intervention, reduces production costs, and improves the efficiency of cutting paper-plastic parts. The main force-applying part and the sub-force-applying part are respectively transmitted to the middle and side of the cutting plate 23 to improve processing accuracy and stability.

[0025] The force applying sub-portion can apply force to the positions of multiple side edges of the cutting plate 23, thereby driving the cutting plate 23 to move up and down. In this embodiment, Figure 2 As shown, the sub-force-applying part includes a fixed seat 241, a guide column 242, a driven sprocket 243, a chain belt 244, a first motor 245 and a driving sprocket. The fixed seat 241 is located above the cutting plate 23, the first motor 245 is connected to the fixed seat 241, and the first motor 245 is driven to connect the driving sprocket. Multiple corner positions of the fixed seat 241 are respectively rotatably connected to the guide column 242, and the tops of the multiple guide columns 242 are respectively and synchronously connected to the driven sprocket 243. The chain belt 244 is transmission-connected to the driving sprocket and the multiple driven sprockets 243, and the bottoms of the multiple guide columns 242 are respectively rotatably connected to the platform 21, and the cutting plate 23 is respectively threadedly connected to the multiple guide columns 242. When it is necessary to drive the cutting board 23 to move up and down, the first motor 245 provides a rotational driving force to the driving sprocket, and the power can be transmitted to the chain belt 244 through the driving sprocket, thereby driving the multiple driven sprockets 243 to rotate, thereby driving the multiple guide pillars 242 to rotate. When the multiple guide pillars 242 rotate, they can provide active driving force from multiple positions of the cutting board 23 respectively, so that the force-applying part applies force to multiple side positions of the cutting board 23, thereby stably driving the cutting board 23 to move up and down.

[0026] The main force-applying part mainly applies force to the middle position of the cutting plate 23, thereby driving the cutting plate 23 to move up and down. In the present embodiment, the main force-applying part comprises a second motor 251, an output connecting rod 252, a crank connecting rod 253 and a slide 254. The second motor 251 is connected to the fixed seat 241. The second motor 251 is driven to connect one end of the output connecting rod 252. The other end of the output connecting rod 252 is rotatably connected to the top end of the crank connecting rod 253. The bottom end of the crank connecting rod 253 is rotatably connected to the slide 254. A guide column 242 is connected to the slide 254. The guide column 242 is slidably connected to the fixed seat 241 along the up and down directions. The slide 254 is transmission-connected to the cutting plate 23. The output connecting rod 252 and the crank connecting rod 253 form a crank rocker structure. When it is necessary to drive the cutting plate 23 to move up and down, the second motor 251 transmits power through the output connecting rod 252 and the crank connecting rod 253, which can drive the slide 254 to move reciprocatingly up and down, thereby driving the cutting plate 23 to cut the workpiece downward and reset it upward.

Since the rotation connection point at the bottom end of the third link 257 is closer to the second link 256, at this time, the distance between the rotation connection point of the third link 257 and the end of the first link 255 close to the second link 256 is smaller than the distance between the rotation connection point of the third link 257 and the end farthest from the first link 255, the third link 257 can drive the first link 255 to rotate with less force.
