The front end of the gear 23 is fixed by a The body is fixedly connected with a handle 5, and the surface of the handle 5 is provided with anti-slip grooves. The bottom end of the driving rod 24 is fixed with a pressing plate 10 through integral molding, and the bottom end of the pressing plate 10 is on the same vertical line as the groove of the second material box 4. The bottom end of the fixed plate 1 is fixed with a fixing rod 22 through integral molding, and the bottom end of the fixing rod 22 is fixed with a bottom plate 2 through integral molding. The outer side of the bottom plate 2 is fixed with a second fixing block 20 through integral molding. There are two second fixing blocks 20, which are respectively fixed at the left and right ends of the driving frame 19. The top end of the second fixing block 20 is tightly pressed against the first material box 3, and a groove is provided inside the first material box 3. The area of the groove of the first material box 3 is the same as that of the pressing plate 10. This arrangement makes it easy to press the mask body inside the first material box 3 or the second material box 4 downward onto the conveyor belt 18.

The left end of the first material box 3 is fixedly connected to the second material box 4 through integral molding, and the rear ends of the second material box 4 and the first material box 3 are fixedly provided with a baffle 7 through integral molding. The conveyor belt 18 can only convey one mask body, and the top mask body of the bottom mask body is blocked by the baffle 7 to prevent the conveyor belt 18 from conveying multiple mask bodies at one time. The bottom end of the second material box 4 is tightly pressed against the driving frame 19, and the interior of the driving frame 19 is tightly pressed against the conveyor belt 18. The interior of the conveyor belt 18 is rotatably connected to the first rotating shaft 6, and the right end of the first rotating shaft 6 is rotatably connected to the second motor 17. The second motor 17 rotates The first rotating shaft 6 is controlled to rotate, thereby controlling the rotation of the conveyor belt 18, and the transmission belt is stretched out by the second rotating shaft 21. The other end of the conveyor belt 18 is rotatably connected to the second rotating shaft 21, and the left and right ends of the second rotating shaft 21 are rotatably connected to the driving frame 19.

When the mask body is conveyed to the bottom end of the fixing frame 9, the material sensor 8 will control the second motor 17 to stop running. When the mask body at the bottom end of the fixing frame 9 moves away, the material sensor 8 controls the second motor 17 to start again When the first material box 3 is on the second fixed blocks 20 on both sides of the driving frame 19, the mask body can be put into the groove of the first material box 3. At this time, the second material box 4 is on the conveyor belt 18. The mask body is slid into the conveyor belt 18, which can improve the work efficiency of the user. After the mask body in the second material box 4 is transmitted, the first fixed block 11 is controlled to move by starting the first motor 16. The first fixed block 11 moves and drives the first material box 3 to the top of the driving frame 19, so that the conveyor belt 18 transmits the mask body in the groove of the first material box 3. At this time, the user puts the mask body into the groove of the second material box 4.

When the user fails to put the mask body neatly into the groove of the first material box 3 or the second material box 4, the mask body in the groove is blocked and the mask body cannot be moved downward, the gear 23 is controlled to rotate by the driving handle 5, and the gear 23 is meshed and connected with the rack 25, thereby driving the driving rod 24 to move downward, and the driving rod 24 drives the pressing plate 10 to move downward, and the mask bodies in the grooves of the first material box 3 and the second material box 4 are pressed out by the support of the fixing plate 1 and the fixing rod 22 on the bottom plate 2, and the driving rod 24 is prevented from moving downward without external force by the spring 13, and is fixedly arranged on the top of the fixing plate 1 by the fixing bolt 14 on the driving plate 12 and another fixing bolt 14, and is on the same vertical line as the fixing bolt 14 on the driving plate 12, to prevent the driving rod 24 from moving excessively.

The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
