The linear conveying module is arranged on the material taking module and is used to drive the grasping module and the metal razor heads to move horizontally. The linear conveying module moves the metal razor heads on the grasping module to the material taking module and places the metal razor heads on the tray on the material taking module. The injection molding module is arranged on one side of the vibrating feeding module and is used to inject and connect the metal razor heads and plastic connectors. The injection molding module mainly consists of an injection molding machine and an injection mold. The metal razor heads are placed on the injection mold through the material taking module, and then the injection molding machine injects and forms the plastic connectors, and presses and connects the metal razor heads and the plastic connectors. The material taking module is arranged on the injection molding module and is used to receive the metal razor heads on the grasping module and convey the metal razor heads to the injection molding module. At the same time, it takes out the injection-molded razor heads. The material taking module drives the tray to rotate at a fixed angle through the operation of the motor, enabling the tray to take out the injection-molded razor heads while performing the feeding function, reducing the waste of operation waiting time and improving the production efficiency.

[0038] Working principle of the present invention: Through the rotation of the second gear 412, the two first gears 411 are driven to rotate together. One of the first gears 411 drives the movable ring 49 to rotate, and the movable rod 46 rotates together with the movable ring 49. One end of the movable rod 46 moves out of the inner cavity of the groove 75, and one end of the movable rod 46 is in contact with the outer wall of the column 2, pushing the other end of the movable rod 46 to penetrate into the inner cavity of the connection hole 74, so that one end of the movable rod 46 pushes the fixed block 45 to rotate, and the fixed block 45 drives the mounting ring 43 to rotate together. The two connecting arms 42 and the fixed disk 41 rotate with the mounting ring 43. The other first gear 411 drives the rotating disk 47 to rotate. When the mounting ring 43 drives the two fixed disks 41 to rotate clockwise by one hundred and thirty-five degrees, the connection between the movable rod 46 and the fixed block 45 is released, and the cogs 48 on the rotating disk 47 and the fixed block 45 are meshed and connected. As the rotating disk 47 rotates, it drives the fixed block 45 and the mounting ring 43 to rotate, driving the two fixed disks 41 to rotate counterclockwise. One of the fixed disks 41 passes above the injection mold 3 and the linear module in sequence for feeding operation, and the other fixed disk 41 passes above the injection mold 3 for discharging operation. And when the connecting arm 42 rotates around the column 2, it drives the pushing block 66 to rotate together, so that the pushing block 66 is pressed against the inner wall of the extrusion groove 69, thereby driving the pushing block 66 to move. The fixed rod 63 and the movable block 62 move together with the pushing block 66. The bottom of the pushing block 66 moves from the position with the largest diameter of the extrusion groove 69 to the position with the smallest diameter, driving the movable block 62 and the fixed disk 41 to perform reciprocating displacement, realizing the telescopic movement of the fixed disk 41.
