When feeding, screws are added into the material box 2, the screws automatically slide into the hopper 3 along the bottom wall of the material box 2, the hopper 3 rotates, the screws are supported by the material lifting plates 31 and then are adjusted into the feeding track 4, the feeding track 4 further conveys the screws into the feeding mechanism 6, the feeding mechanism 6 blows the screws into a screw gun by compressed air, and thus the automatic feeding process is completed.

[0032] With reference to Figure 2 , Figure 3 , the lifting plates 31 are bent in the same direction, and the bending direction of the lifting plates 31 is consistent with the rotating direction of the hopper 3. During the rotation of the hopper 3, the bending arrangement of the lifting plates 31 enables the screws to be held in the lifting plates 31 to prevent falling, and the screws will only fall from the lifting plates 31 when the lifting plates 31 are transported to be higher than the feeding track 4, thereby ensuring that the screws can fall into the feeding track 4.

[0033] With reference to Figure 2 , Figure 3 , the inner wall of the hopper 2 is fixedly connected with baffles 22, the baffles 22 are provided with two and are located on both sides of the material passage 21, the distance between the baffle 22 and the side wall of the hopper 2 gradually increases away from the bottom wall of the hopper 2, the bottom wall of the baffle 22 and the inner bottom wall of the hopper 2 form a feeding hole 23, the two baffles 22 form a screw-preventing standby material space 24, and the baffle 22 and the inner wall of the hopper 2 form a discharging space 25. The feeding track 4 is located in the standby material space 24. During the feeding process in the operation of the equipment, the screws can first enter the discharging space 25, and then slide into the inside of the standby material space 24 through the feeding hole 23, so that during the feeding process, the screws will not fall into the track from above to cause the screws that have been arranged to be rearranged, thereby preventing abnormality in the conveying process.

[0034] In the embodiment of the present application, the top wall of the feeding hole 23 is lower than the lower edge of the feeding track 4, thereby effectively preventing the screws in the standby material space 24 from being accumulated to be higher than the feeding track 4, and ensuring that the track can normally convey the screws.

[0035] With reference to Figure 4 , the feeding track 4 includes a rejection track 41 arranged inside the hopper 2 and a conveying track 42 arranged outside the hopper 2, the conveying track 42 is fixedly connected with a vibrator 43 at the bottom, the conveying track 42 includes a bottom plate 421, side plates 422 fixedly connected on both sides of the bottom plate 421, and a scrap receiving plate 423 arranged below the bottom plate 421 and fixedly connected with the two side plates 422, and the bottom plate 421 is provided with through holes 424 for falling of the scraps. During the conveying process, some screws may have scraps remaining thereon, the vibrator 43 drives the conveying track 42 to convey the screws, and at the same time, the scraps can be shaken off and fall into the scrap receiving plate 423, and the scraps are transported together in the scrap receiving plate 423, thereby preventing the occurrence of material jamming during the conveying process.

The stirring plate 512 is fixed on the rotating shaft 511 by screws, and the rotating shaft 511 is arranged inside the feeding hole and above the rejection track 41 respectively. The stirring structure 51 above the rejection track 41 cooperates with the material falling hole 411 to stir the improperly positioned screws downward, thereby preventing the feeding track 4 from being blocked and causing poor material conveying. The stirring structure 51 inside the feeding hole can break the bridging phenomenon in the material space 25, thereby ensuring that the screws can slide into the material space 24 from the feeding hole and ensuring that the screws can continuously and smoothly fall into the hopper 3.

[0037] The pulley 513 is arranged on the outer wall of the material box 2, and a synchronous belt 514 is engaged with the outer periphery of the pulley 513.

One end of the connecting rod 523 close to the driving motor 521 is eccentrically arranged, and the other end is rotatingly connected to the end of the rocker arm 522 away from the rotating shaft 511. The connecting rod 523 converts the rotary motion of the output shaft of the driving motor 521 into the reciprocating motion of the rocker arm 522, and the eccentric arrangement makes the rocker arm 522 drive the stirring plate 512 to perform stable swinging motion, thereby effectively rejecting the improperly positioned screws.

The clamping groove 621 is provided with at least two, and the distance between adjacent clamping grooves 621 is equal to the distance between the discharge pipe 64 and the placing groove 611. The provision of multiple clamping grooves 621 can realize parallel conveying, one clamping groove 621 receives the screws conveyed by the feeding track while the other clamping groove 621 is just opposite the discharge pipe 64, thereby simultaneously performing the actions of receiving screws and conveying screws, eliminating waiting time and greatly improving the feeding efficiency.
