DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 A pre-stocked automatic screw machine comprises a machine body 1 and a sliding track 2 fixed on the upper end of the machine body 1, a fixing machine 3 is slidably arranged on the sliding track 2, a hopper 4 is fixedly connected to both sides of the upper end of the machine body 1, and a circulation trigger is fixedly connected to the end of the hopper 4 within the range of the machine body 1, and the circulation trigger is matched with the end of the fixing machine 3, and a feeding piece is arranged in the hopper 4, and the feeding piece is matched with the circulation trigger.

[0022] Specific working principle and implementation method: the fixing machine 3 moves horizontally on the sliding track 2, and the fixing machine 3 is driven up and down by the cylinder. The fixing machine 3 absorbs the screws from the feeding piece in the hopper 4 to perform a fixing operation. When the fixing machine 3 absorbs the screws through the cylinder, the circulation trigger part is triggered, and the circulation trigger part drives the feeding piece so that the pre-stored screws can be continuously fed. The advantage of this design is that after the screws are fixed, the fixing machine 3 moves to both sides to take the material through the magnetic screw. When the fixing machine 3 moves downward, it first magnetically absorbs the screws, and then moves upward to trigger the circulation trigger part, and then the next screw that needs to be magnetically absorbed is fed, and the screws are placed on the feeding piece and circulated through the circulation trigger part.

[0023] like Figure 2 and Figure 4As shown, the circulation triggering member includes a fixing frame 5 fixed on both sides of the upper end of the hopper 4, a guide groove 6 is provided on the inner side of the fixing frame 5, a triggering block 7 is arranged between the two fixing frames 5, both ends of the triggering block 7 are fixedly connected with guide rods 8 located in the guide groove 6, a material taking hole 9 is provided on the upper end of the triggering block 7, a spring 10 is fixedly connected to the lower end of the triggering block 7, both sides of the lower end of the triggering block 7 are fixedly connected with limit stops 11, the lower end of the limit stop 11 is fixedly connected with a connecting member 12, a triggering rod 13 is rotatably connected in the connecting member 12, and the triggering rod 13 is rotatably connected in the inner side of the connecting member 12. 13 is matched with both sides of the end of the feeding piece, and the trigger rod 13 is arranged on the limit stop 11 below. When the fixing machine 3 presses the fixing frame 5 downward, the spring 10 is compressed. At this time, the fixing machine 3 magnetically attracts the screw, and the fixing machine 3 moves upward after magnetically attracting the screw, and drives the trigger rod 13 to move upward when moving upward. The trigger rod 13 can drive the feeding piece to operate upward, and then the pre-stored screws can be continuously fed. When the trigger rod 13 moves downward, it hits the feeding piece and rotates upward. When it moves upward, it will be blocked by the limit stop 11 to drive the feeding piece.

[0024] like Figure 2 and Figure 5 As shown, the feeding member includes a driving roller 14 rotatably connected to one end of the inner side of the hopper 4, gears 19 are fixedly connected to both sides of the driving roller 14, and the trigger rod 13 is matched with the gear 19 and arranged accordingly. A driven roller 15 is rotatably connected to the other end of the inner side of the hopper 4, and a tooth groove 18 is provided on the driving roller 14. A feeding belt 16 is sleeved on the driving roller 14 and the driven roller 15. The inner side of the feeding belt 16 is matched with the tooth groove 18, and a plurality of fixed cylinders 17 are fixedly connected to the outer end of the feeding belt 16. The trigger rod 13 is downward. When moving, it will contact with the gear 19. At this time, the trigger rod 13 has rotation space and will rotate upward. After the fixing machine 3 is magnetically attracted to the screw, it moves upward. At this time, the trigger rod 13 is restricted by the limit stop 11, and the trigger rod 13 is located in the meshing position of the gear 19, thereby driving the gear 19 to rotate. The rotation of the gear 19 drives the driving roller 14 to rotate. The tooth groove 18 provided on the driving roller 14 is used to drive the conveyor belt 16 to rotate, and then the fixing cylinder 17 fixed at the upper end of the conveyor belt 16 can be rotated to the position for the next feeding.

[0025] like Figure 5 As shown, a ratchet 20 is fixedly connected to the outer end of the gear 19, and a rotating rod 21 is rotatably connected to the inner end of the hopper 4. A pawl 22 meshing with the ratchet 20 is fixedly connected to the rotating rod 21. Through the arrangement of the ratchet 20 and the pawl 22, the gear 19 will rotate when it rotates in the reverse direction, thereby preventing the gear 19 from rotating clockwise and making the overall operation more stable and smooth.

[0026] like Figure 4As shown, the trigger rod 13 is arranged in a folded shape. The trigger rod 13 is arranged in a folded shape so that the trigger rod 13 can rotate upward in advance when it touches the gear 19, and can quickly engage with the gear 19 to drive the conveyor belt 16 when moving upward.

[0027] like Figure 4 As shown, one end of the connecting member 12 is sleeved with a torsion spring, and the other end of the torsion spring is fixedly connected to the rotating end of the trigger rod 11. The torsion spring drives the rotation of the trigger rod 13. After the trigger rod 13 rotates upward, it can quickly return to its original position to prevent the trigger rod 13 from affecting the meshing with the gear 19.
