The stirrup feeding unit 1000 coarsely limits the position of the stirrup sent out through the inner side surfaces of the two limiting plates 1003, but the distance between the two limiting plates 1003 cannot be equal to or smaller than the size of the stirrup, otherwise, the stirrup is blocked to influence the feeding, and the lever type precise limiting mechanism is used, so that the sending end positions of the two limiting plates 1003 are provided with two action surfaces 1094 which respectively protrude out of the inner side surfaces, when in implementation, the distance between the two action surfaces 1094 is smaller than or equal to the size of the stirrup, the gap between the inner side surfaces of the two limiting plates 1003 and the stirrup can be compensated, the precise limiting effect is achieved, the stirrup can be sent out precisely according to the design position, the action surface 1094 is a flexible contact surface provided through one end of the lever action plate 1009, even if the distance between the two action surfaces 1094 is smaller than the size of the stirrup, when the stirrup passes through, the lever movement can compress the elastic element 1095 to achieve the effect of effective abdication and keeping the limiting action force, the accurate sending-out position is effectively limited, and simultaneously, the stirrup cannot be clamped, and the feeding and sending-out effects are guaranteed. The stirrup is acted on the inner side surfaces of the two limiting plates 1003 from the left direction and the right direction, the part of the lower surface of the vertical sliding block 1008 protruding out of the inner side surfaces of the limiting plates 1003 can act on the stirrup from top to bottom, so that the effect of limiting the stirrup from the periphery is achieved, the feeding position and posture are better guaranteed, and the welding machine unit 2000 is convenient to link up. The mode that vertical slider 1008 adopted the top-and-bottom slip is because the limiting plate 1003 has carried out the restriction of rigidity from the left right direction, if vertical slider 1008 also carries out the rigidity of height direction spacing, the lower surface of vertical slider 1008 is low excessively, the distance from the barrel 1002 is nearer promptly, the circumstances that the stirrup can't be sent into between two limiting plates 1003 and vertical slider 1008 below can appear, so, during the use, vertical slider 1008 is located vertical gliding high point earlier, let the stirrup send into between two limiting plates 1003 earlier, the vertical lapse of rethread vertical slider 1008, top-down effect stirrup, keep sending out the gesture and do not influence the sending of stirrup again. During implementation, the distance between the two limiting plates 1003 can be adjusted to improve the applicability, the movement of the two limiting plates 1003 can be electrically controlled, and the sending-out position of the stirrup sent by the limiting plates 1003 can be limited through the movement of the limiting plates 1003.

A connecting lug is arranged on the outer side surface of the limiting plate 1003, and the middle part of the lever action plate 1009 is connected with the connecting lug through a vertical rotating shaft 1096; the positioning portion 1093 is a boss provided on a surface of the action end 1092 opposite to the outer side surface of the limit plate 1003.

Therefore, the connecting structure is simple, the action and the positioning are reliable, and the using effect is guaranteed.

The free end of the action end 1092 extends out of the sending-out end of the limit plate 1003 and continues to extend towards the inner side of the limit plate 1003 to form two horizontal flanks 1097, the two horizontal flanks 1097 are vertically and horizontally arranged in an opposite mode, a vertical fine correction roller 1098 is rotatably connected between the two horizontal flanks 1097, and the outer circumferential surface of the fine correction roller 1098 is formed into the action surface 1094.

Thus, the contact during the precise restraint is also changed from the sliding friction between the stirrup and the original acting surface 1094 to the rolling friction between the stirrup and the fine aligning roller 1098, which is more advantageous for the feeding process and does not scratch the stirrup.

Wherein the limiting plate 1003 is long, an upward convex edge 1031 protruding inwards is arranged on the upper edge of the limiting plate 1003, the limiting plate is connected with a plurality of rotatable vertical rollers 1004 through the upward convex edge 1031, all the vertical rollers 1004 are vertical, the upper ends of the vertical rollers 1004 are rotatably connected with the upward convex edge 1031, all the vertical rollers 1004 are arranged at intervals along the limiting plate 1003, the vertical rollers 1004 are positioned between two adjacent rollers 1002 such that the vertical rollers 1004 and the rollers 1002 are in an alternating configuration, the lower edge of the limiting plate 1003 is provided with downward extensions 1032 corresponding to the vertical rollers 1004 one by one, the extensions 1032 are also located between two adjacent rollers 1002, and an inwardly projecting lower ledge 1033 is provided at the lower edge of the extension 1032, the upper surface of the lower ledge 1033 being lower than the highest point of the outer circumference of the roller barrel 1002 (i.e., the plane of the feed stirrup), the lower ends of the vertical rollers 1004 are rotatably connected with the corresponding lower flanges 1033 so as to act as stirrups through the vertical rollers 1004 and ensure the stability of the vertical rollers 1004; the outer circumference of the fine roller 1098 protrudes from the outer circumference of the vertical roller 1004 in a direction toward the inside of the limit plate 1003, that is, the highest point of the outer circumference of the fine roller 1098 is higher than the highest point of the outer circumference of the vertical roller 1004.

Thus, the distance between the roller cylinders 1002 is skillfully utilized, the lower ends of the vertical rollers 1004 are connected with the convex edges of the extension parts 1032 extending downwards from the limiting plate 1003, the vertical rollers 1004 can be effectively contacted and acted on the stirrups, meanwhile, the connection stability of the vertical rollers 1004 is effectively improved, the use time limit can be greatly prolonged, and the use effect can be always guaranteed.

Therefore, a feasible driving connection mode is provided, the connection is simple, and the force transmission is reliable.

At least two ends of the limiting plate 1003 are respectively provided with one vertical slider 1008.

Thus, the effect of restricting the posture of the stirrup can be improved, and theoretically, a vertical sliding block 1008 can be arranged between every two adjacent vertical rollers 1004; when only one vertical slide block 1008 is arranged on one limiting plate 1003, the vertical slide block is preferably arranged at the sending-out end of the limiting plate 1003; in this embodiment, two vertical sliding blocks 1008 (including corresponding telescopic cylinders 1083) are provided on one limiting plate 1003, and are preferably respectively provided at two ends of the limiting plate 1003, so as to ensure the effect of limiting the posture of the stirrup.

Wherein, two limiting plates 1003 continue to extend respectively towards the one end of supplied materials and are equipped with deflector 1005, and the interval of two deflector 1005 enlarges gradually in order to guarantee the direction effect and increase the direction scope of action.
