When cutting and conveying, there may be partial bending or wrinkling, which affects the positioning accuracy of the positioning mechanism 2 and the cutting accuracy. Therefore, please refer to Figures 1 to 6 In some possible embodiments, the cutting positioning device is also equipped with a flattening mechanism 3 and a feeding mechanism 4. The flattening mechanism 3 is installed on the feeding side of the cutting mechanism 1, and its main function is to flatten the material to be cut, ensuring that the material is flat and wrinkle-free before entering the cutting link, thereby helping to improve the cutting accuracy and efficiency.

The guide direction of the guide 22 is consistent with the length direction of the material conveying channel. The flattening mechanism 3 and the positioning mechanism 2 are respectively arranged at the feeding end and the discharging end of the material conveying channel, so that the oil net is first flattened by the flattening mechanism 3 during the conveying process to remove possible bending or wrinkling, and then smoothly conveyed to the positioning mechanism 2 by the feeding mechanism 4. The stopper 21 in the positioning mechanism 2 is accurately positioned according to the preset cutting size, and the guide 22 ensures the stability and accuracy of the stopper 21. Then, the cutting mechanism 1 is started, and the cutting knife 11 reciprocates under the action of the driving part 12, and the pressing plate 13 presses the oil net stably to ensure the smooth progress of the cutting process.

The unwinding roller 42 is installed at the feeding position of the material passing groove, the driving motor 43 is installed on one side of the workbench 41, the driving shaft of the driving motor 43 is connected with the unwinding roller 42, for driving the unwinding roller 42 to rotate, so as to gradually unwind the oil net in the form of a roll.

The design makes the oil net be flattened by the flattening mechanism 3 before being cut, so as to remove the wrinkles and bending, and then the oil net is stably conveyed to the positioning mechanism 2 through the feeding mechanism 4, so as to ensure the cutting precision and efficiency.

[0042] It should be noted that, in the embodiment, the driving assembly 33 is a pneumatic cylinder, a hydraulic cylinder or an electric push rod, etc. In addition, the top surface of the conveying belt 44 is above the bottom plate 31, and when the flattening operation is performed, the driving motor 43 needs to be stopped, so that the conveying belt 44 is kept in a stationary state, so as to avoid interference with the flattening operation.
