The shape of the discharge groove 201 is not fixed, and the PIN 9 can slide down to the bottom end of the discharge groove 201 in the discharge groove 201 according to the needs. The bottom end of a discharging frame 2 is provided with a 203, the bottom end of a discharging groove 201 and a discharging hole 202 are communicated with the 203, a feeding roller 3 is rotationally inserted in the 203 and is coaxial with the 203, the outer peripheral surface of the feeding roller 3 is in sliding fit or close to fit with the inner wall of the 203, the bottom end of the discharging groove 201 is positioned in a first quadrant or a second quadrant of a quadrant angle formed by the center of the feeding roller 3, so that a PIN needle 9 in the discharging groove 201 can fall on the feeding roller 3 under the action of gravity, the discharging hole 202 is positioned in a third quadrant or a fourth quadrant of the quadrant angle formed by the center of the feeding roller 3, and the PIN needle 9 falling on the feeding roller 3 can be automatically discharged from the discharging hole 202 when the feeding roller 3 rotates through the discharging hole 202.
The outer circumferential surface of the feeding roller 3 is circumferentially provided with a plurality of accommodating grooves 301, the bottom surface of each accommodating groove 301 is an arc surface or a plane, the left side surface and the right side surface are planes parallel to the warp direction surface of the feeding roller 3, the width of an opening of each accommodating groove 301 is not smaller than the diameter of a PIN needle 9, the length of the opening of each accommodating groove 301 is not smaller than the length of each PIN needle 9, so that each accommodating groove 301 can accommodate the PIN needle 9, and the feeding roller 3 drives the plurality of accommodating grooves 301 to sequentially pass through the discharging groove 201 when rotating so that the lowest PIN needle 9 in the discharging groove 201 falls into the corresponding accommodating groove 301 to be conveyed. When the accommodating groove 301 accommodating the PIN 9 passes through the discharge hole 202 in the process of rotation, the PIN 9 can be discharged from the discharge hole 202 under the action of gravity of the PIN 9, the discharged PIN 9 falls on the top of the receiving plate 5, the top of the receiving plate 5 is inclined downwards in a direction away from the feeding roller 3, and after the PIN 9 discharged from the discharge hole 202 falls on the receiving plate 5, the PIN 9 continuously rolls along the top surface of the receiving plate 5 in a direction away from the feeding roller 3 under the action of gravity of the PIN 9.
Because the material receiving plate 5 is slidably inserted with the plurality of movable blocks 7, the sliding direction of the movable blocks 7 is the vertical direction, the plurality of movable blocks 7 are arranged at intervals along the rolling direction of the PIN needle 9, the material receiving plate 5 is elastically slidably inserted with the push plates 6 which are intermittently linked with the feed roller 3 and are sequentially slidably abutted to the bottom ends of the plurality of movable blocks 7, the sliding direction of the push plates 6 is the horizontal direction, so that the feed roller 3 can be in a state of being linked with or not linked with the push plates 6 in one rotation period of the feed roller 3, the push plates 6 are in an initial state when the feed roller 3 is not linked with the push plates 6, the push plates 6 can be driven to slide towards the direction of the feed roller 3 when the feed roller 3 is linked with the push plates 6, the sliding of the push plates 6 pushes the plurality of movable blocks 7 to sequentially rise, and the ascending sequence of the plurality of movable blocks 7 is from far to near relative to the feed roller 3; meanwhile, in one rotation period of the feed roller 3, the PIN needles 9 in the discharge groove 201 can be driven to be discharged from the discharge holes 202 one by one and fall on the top of the receiving plate 5, the time of each PIN needle 9 discharged from the discharge holes 202 is later, and the rising time of each movable block 7 is earlier.
The specific working principle is as follows: in the initial state, the feeding roller 3 is not linked with the push plate 6, and the push plate 6 is in the initial state (refer to fig. 11); starting the feeding roller 3 to rotate, while the rotating feeding roller 3 drops the PIN needle 9 in the discharging groove 201 in the accommodating groove 301 and continuously drives the PIN needle 9 to rotate towards the discharging hole 202, and simultaneously is linked with the pushing plate 6 to drive the pushing plate 6 to elastically slide towards the feeding roller 3, the pushing plate 6 continuously approaches to the movable block 7 far away from the feeding roller 3 in the process of elastically sliding, when the pushing plate 6 abuts against the movable block 7 far away from the feeding roller 3 and pushes the movable block 7 to rise, the accommodating groove 301 (namely, the first accommodating groove 301) accommodating the PIN needle 9 is overlapped with the discharging hole 202 so that the PIN needle 9 in the accommodating groove 301 is discharged through the discharging hole 202 and drops on the top of the material connecting plate 5, then the PIN needle 9 rolls along the direction of the movable block 7 with the top surface of the material connecting plate 5 upwards, the top of the raised movable block 7 protrudes out of the top of the material connecting plate 5, and the PIN needle 9 drops on the movable block 5 before the rising, so that the PIN needle 9 drops on the movable block 5, and the PIN 9 can be blocked by the movable block 7 after the PIN needle 9 drops on the material connecting plate 5, and the PIN 9 can be blocked by referring to the first drawing (see fig. 14); the push plate 6 pushes the second movable block 7 to rise, and at the same time, the next accommodating groove 301 accommodating the PIN 9 (i.e. the second accommodating groove 301) coincides with the discharge hole 202 so that the second PIN 9 falls on the material receiving plate 5 to roll until the second PIN 9 abuts against the second rising movable block 7, thereby realizing the arrangement of the second PIN 9 (refer to fig. 15). And the like, until a plurality of PIN needles 9 discharged in one rotation period of the feeding roller 3 are abutted with a plurality of ascending movable blocks 7 one by one, the arrangement work of the PIN needles 9 is realized, and the PIN needles 9 are in one-to-one correspondence with a plurality of ejector PINs 11 after the arrangement is finished.
