[0065] The technical effects and advantages of this invention are as follows:

[0066] This invention utilizes a combination of a second gear, a first gear, a mounting ring, a movable ring, a fixed block, a locking tooth, a rotating disk, and a movable rod. The rotation of the second gear drives two first gears to rotate together. One of the first gears drives the movable ring to rotate, and the movable rod rotates with the movable ring. One end of the movable rod pushes the fixed block to rotate, which in turn drives the mounting ring to rotate. The two connecting arms and the fixed disk rotate with the mounting ring. The other first gear drives the rotating disk to rotate. When the mounting ring drives the two fixed disks to rotate 135 degrees clockwise, the connection between the movable rod and the fixed block is released, and the locking tooth on the rotating disk and the fixed block engages. As the rotating disk rotates, it drives the fixed block and the mounting ring to rotate, causing the two fixed disks to rotate counterclockwise. One fixed disk passes over the injection mold and the linear module sequentially for loading, while the other fixed disk passes over the injection mold for unloading, thus achieving automated loading of shaver heads and improving production efficiency.

[0067] This invention utilizes a combination of a connecting arm, a pushing block, a fixed rod, a movable block, and an extrusion groove. The connecting arm drives the pushing block to rotate, causing the pushing block to press against the inner wall of the extrusion groove, thereby moving the pushing block. The fixed rod and the movable block move together with the pushing block. The bottom of the pushing block moves from the position of maximum diameter of the extrusion groove to the position of minimum diameter, driving the movable block and the fixed plate to move back and forth, thus realizing the telescopic movement of the fixed plate.

[0068] This invention utilizes a combination of a movable ring, a movable rod, a second compression spring, a groove, and a connecting hole. The movable ring drives the movable rod to rotate together. When one end of the movable rod rotates into the inner cavity of the groove, the elasticity of the second compression spring pushes the movable rod inward, causing one end of the movable rod to separate from the connecting hole and disconnect the movable rod from the fixed block. When one end of the movable rod moves out of the inner cavity of the groove, it comes into contact with the outer wall of the column, pushing the other end of the movable rod to insert into the inner cavity of the connecting hole, causing the movable rod to drive the fixed block to rotate together.

[0086] Specifically, the feeding mechanism 4 includes fixed plates 41, which are symmetrically arranged on both sides of the column 2. These fixed plates 41 are used to fix and install the suction plates and drive their movement. The included angle between the two fixed plates 41 is 135 degrees. One fixed plate 41 is used for feeding the shaver head, and the other fixed plate 41 is used for unloading the shaver head after injection molding. The two fixed plates 41 drive the two suction plates to reciprocate, completing the loading and unloading operations. A connecting arm 42 is also included, with one end positioned above the fixed plates 41. The connecting arm 42 connects the fixed plates 41 and the mounting ring 43, driving the fixed plates 41 forward. The mounting ring 43, which is interlocked with the column 2, consists of two semi-circular rings. The mounting ring 43 is used to mount the fixing plate 41 and connecting arm 42 onto the column 2, and drives the fixing plate 41 to rotate around the column 2. A connecting rod 44, one end of which is fixedly connected to the outer wall of the mounting ring 43, is used to connect the fixing block 45. A fixing block 45, one end of which is fixedly connected to the other end of the connecting rod 44, is arc-shaped and rotates with the mounting ring 43. A movable rod 46 is located inside the fixing block 45 and is used for... The fixed block 45 is rotated by the movable ring 46, which is located between the movable ring 49 and the fixed block 45, causing the mounting ring 43 to rotate the fixed block 45 clockwise. A rotating disk 47 is located outside the column 2 and is used to rotate the fixed block 45 and the mounting ring 43 counterclockwise.

The first gear 411 is fixedly interlocked with both the movable ring 49 and the fixed shaft 410. The first gear 411 is used to drive the movable ring 49 and the fixed shaft 410 to rotate.The second gear 412 is positioned between the first gears 411 and meshes with them. The two first gears 411 mesh with opposite sides of the second gear 412. Rotation of the second gear 412 causes both first gears 411 to rotate together. One of the first gears 411 drives the movable ring 49 to rotate, causing the movable rod 46 to rotate as well. One end of the movable rod 46 pushes the fixed block 45 to rotate, which in turn drives the mounting ring 43 to rotate. The two connecting arms 42 and the fixed plate 41 rotate with the mounting ring 43. As the rotating disc 47 rotates, the other first gear 411 drives the rotating disk 47 to rotate as well. When the mounting ring 43 drives the two fixed disks 41 to rotate 135 degrees clockwise, the connection between the movable rod 46 and the fixed block 45 is released, and the locking teeth 48 on the rotating disk 47 and the fixed block 45 engage. As the rotating disk 47 rotates, it drives the fixed block 45 and the mounting ring 43 to rotate, causing the two fixed disks 41 to rotate counterclockwise. One fixed disk 41 passes over the injection mold 3 and the linear module in sequence for loading, while the other fixed disk 41 passes over the injection mold 3 for unloading.

The injection molding module is located to one side of the vibratory feeding module. The injection molding module is used to connect the metal cutter head to the plastic connector for injection molding. The injection molding module mainly consists of an injection molding machine and an injection mold. The material handling module places the metal cutter head onto the injection mold, and the injection molding machine then injection molds the plastic connector, pressing the metal cutter head and plastic connector together. The material handling module is located on the injection molding module. It receives the metal cutter head from the gripping module and conveys it to the injection molding module. Simultaneously, it removes the injection-molded razor head. The material handling module uses a motor to rotate the material tray at a fixed angle, allowing the tray to simultaneously feed material and remove the injection-molded razor head, reducing waiting time and improving production efficiency.

[0091] The working principle of this invention is as follows: The rotation of the second gear 412 drives the two first gears 411 to rotate together. One of the first gears 411 drives the movable ring 49 to rotate, and the movable rod 46 rotates along with the movable ring 49. One end of the movable rod 46 moves out of the inner cavity of the groove 75, and the other end of the movable rod 46 fits against the outer wall of the column 2, pushing the other end of the movable rod 46 into the inner cavity of the connecting hole 74. This causes one end of the movable rod 46 to push the fixing block 45 to rotate, and the fixing block 45 drives the mounting ring 43 to rotate together. The two connecting arms 42 and the fixing disk 41 rotate with the mounting ring 43. The other first gear 411 drives the rotating disk 47 to rotate together. When the mounting ring 43 drives the two fixing disks 41 to rotate clockwise by 135 degrees, the connection between the movable rod 46 and the fixing block 45 is released, and the rotating disk 47... The 7 and the fixed block 45 are engaged by the 48. As the rotating disk 47 rotates, it drives the fixed block 45 and the mounting ring 43 to rotate, which in turn drives the two fixed disks 41 to rotate counterclockwise. One fixed disk 41 passes over the injection mold 3 and the linear module in sequence to perform the loading operation, and the other fixed disk 41 passes over the injection mold 3 to perform the unloading operation. 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 maximum diameter position of the extrusion groove 69 to the minimum position, which drives the movable block 62 and the fixed disk 41 to move back and forth, realizing the telescopic movement of the fixed disk 41.
