The linear driving piece 19 is installed on the installation seat 11, and the lifting plate 20 is connected to the linear driving piece 19 in a transmission manner and is used for moving linearly under the drive of the linear driving piece 19. Two links 21 are connected between the lifter plate 20 and the two rocker arms 14, respectively, to convert the linear movement of the lifter plate 20 into rotation of the rocker arms 14. One end of the link 21 is rotatably connected to the lifter plate 20 and the other end is rotatably connected to the rocker arm 14 at a position between the first end 16 and the second end 17.

Alternatively, a bearing hole is formed at one end of the connecting rod 21 connected to the lifting plate 20, and a rolling bearing 23 (e.g., flange-type deep groove ball bearing) is respectively inserted into the front and rear surfaces of the bearing hole, and a bearing sleeve 25 is inserted into the rolling bearing 23 and then locked to the lifting plate 20 by a screw 24. The two sets of links 21 are connected mirror symmetrically to both sides of the lifter plate 20 and ensure that the height of both links 21 and the swing arms 14 are identical when they are actuated. In other embodiments, the connecting rod 21 may also be engaged with the lifter plate 20 in other manners.

One end of the connecting rod 21 connected with the rocker arm 14 is provided with a bearing hole, the front surface and the rear surface of the bearing hole are respectively embedded into a rotary bearing 23 (such as a flange type deep groove ball bearing), and a bearing sleeve 25 is embedded into the rotary bearing 23; the rocker arm 14 is connected with a connecting pin shaft 26, the connecting pin shaft 26 is pressed into a rotating bearing 23 on the connecting rod 21, the rotating connection of the rocker arm 14 and the connecting rod 21 is realized, and the axial limit of the rocker arm 14 and the connecting rod 21 is realized through a screw 24 connected with the connecting pin shaft 26.

In this embodiment, the mounting base 11 is provided with a guide shaft 27, and the axis of the guide shaft 27 is parallel to the direction of linear movement of the lifter plate 20. The lifting plate 20 is connected with a linear bearing 28, and the linear bearing 28 is slidably engaged with the guide shaft 27. The linear bearing 28 may be provided with external threads on the outer peripheral surface and fixedly connected to the threaded hole on the mount 11 by screw-fitting. The movement accuracy of the movement of the lifter plate 20 can be improved by the linear guide of the guide shaft 27 and the linear bearing 28.

In this embodiment, the lifting plate 20 is provided with a fitting groove 29 concavely formed from one side, and two groove surfaces of the fitting groove 29 are respectively convexly provided with a clamping strip 30. The linear driving member 19 is connected to a connection block 31, and the connection block 31 may be formed in a substantially cylindrical shape, and one end of the connection block 31 is connected to the linear driving member 19, and the other end is fitted into the fitting groove 29. The connecting block 31 is provided with two opposite clamping grooves 32 at one end in the matching groove 29, and the two clamping grooves 32 are respectively clamped and matched with the two clamping strips 30. The lifting plate 20 is connected with a baffle 33, and the baffle 33 is blocked at the notch of the clamping groove 32 to limit the connection block 31 from falling out of the clamping groove 32.

When the hydraulic buffer 34 is installed, the upper end of the hydraulic buffer 34 is fixedly arranged, and the lower end of the hydraulic buffer abuts against the lifting plate 20, so that when the lifting plate 20 is driven by the linear driving piece 19 (such as the linear cylinder 22) to lift, the hydraulic buffer 34 can absorb the impact during part of lifting action. In addition, the distance of contact of the feed roller 15 with the target 200 can be adjusted by adjusting the hydraulic damper 34.

In this embodiment, the friction ring 18 may be optionally fitted around the outer circumference of the feed roller 15 to ensure contact friction between the feed roller 15 and the target 200.

The two rocker arms 14 form a V shape with an included angle capable of being increased or decreased, and the connecting line of the driving pulley 36 and the driven pulley 37 is parallel to the extending direction of the rocker arms 14. Alternatively, in a plane perpendicular to the axis of the rotary drive 35, the projections of the line connecting the center points of the driving pulley 36 and the driven pulley 37 and the line connecting the centers of rotation of both ends of the rocker arm 14 coincide. In this way, the synchronous belt 38 is kept from loosening or being excessively lengthened while the feeding roller 15 and the driven pulley 37 are synchronously rotated during the rotation of the rocker arm 14.

The mounting seat 11 of the feeding assembly 10 may be fixedly arranged to fixedly support the feeding assembly 10 as a whole at a suitable height. The feeding roller 15 can move along with the rocker arm 14 under the driving of the first driving component 12 to press the target piece 200 onto the supporting rail 101, and rotate under the driving of the second driving component 13 to convey the target piece 200 along the supporting rail 101.

In the state shown in fig. 4, the linear driving member 19 drives the lifting plate 20 to lift, and further drives the two rocker arms 14 to rotate upwards through the two connecting rods 21, so that the feeding roller 15 is located at a position far from the supporting track 101;
