Referring to fig. 1, an embodiment of the present invention provides a blanking control mechanism 45, which includes a horizontal mounting substrate 450, a horizontal pushing driving cylinder 451 transversely disposed on the horizontal mounting substrate 450, a guiding plate 452 connected to an output end of the horizontal pushing driving cylinder 451 and longitudinally disposed, a sliding rail 453 disposed on a lower end surface of the horizontal mounting substrate 450, a sliding block 454 disposed on the sliding rail 453 and connected to the guiding plate, a connecting block 455 connected to a lower end of the guiding plate 452, and a blanking control block 456 connected to an end of the connecting block 455 and inserted into the horizontal moving cavity 422, wherein a blanking opening 4561 is formed on the blanking control block 456, and the guiding plate is L-shaped.

The blanking control mechanism 45 provided by the embodiment is particularly suitable for a full-automatic metal nut implanting machine. In addition to the blanking control mechanism, as shown in fig. 1 and 2, the full-automatic metal nut implanting machine further includes a machine table 1, at least one carrying tray 2 disposed on the machine table 1, a lifting driving mechanism 3 erected on the machine table 1 and connected to the transverse mounting substrate 450, a metal nut implanting mechanism 4 including the blanking control mechanism 45, and a nut feeding mechanism 5 connected to the metal nut implanting mechanism 4. The metal nuts 10 are fed to the metal nut implanting mechanism 4 through the nut feeding mechanism 5, the lifting driving mechanism 3 drives the nut feeding mechanism 5 to integrally move up and down, so that the metal nuts 10 are fed into the plastic strips 20 on the loading disc 2 one by one through the metal nut implanting mechanism 4, as shown in fig. 7, automatic feeding operation of the metal nuts 10 is completed, and compared with manual operation, the automatic feeding device is high in automation degree and obviously improves working efficiency.

In this embodiment, as shown in fig. 1, the metal nut implanting mechanism 4 includes a blanking base 42 connected to the lower end of the horizontal mounting substrate 450, a hollow blanking heating tube 43 disposed below the blanking base 42, a nut positioning assembly 44 disposed on the blanking base 42, and the blanking control mechanism 45 slidably disposed on the side of the blanking base 42, wherein a vertical blanking chamber 421 located between the nut positioning assembly 44 and the hollow blanking heating tube 43, and a horizontal moving chamber 422 for inserting one end of the blanking control mechanism 45 movably and communicating with the vertical blanking chamber 421 are formed in the blanking base 42, and a feeding hole 423 communicating with the side of the vertical blanking chamber 421 is formed in the blanking base 42.

The metal nuts 10 conveyed by the nut feeding mechanism 5 enter the longitudinal blanking chamber 421 one by one through the feeding hole 423, and only one metal nut 10 enters the longitudinal blanking chamber 421 at the same time. After the metal nuts 10 enter the longitudinal blanking cavity 421, the metal nuts 10 are controlled by the blanking control mechanism 45 to fall into the hollow blanking heating tube 43 one by one; then, the metal nuts 10 are fed into the mounting holes of the plastic strips 20 on the carrier tray 2 through the hollow blanking heating tubes 43; next, the nut positioning assembly 44 positions the metal nut 10; and because the metal nut 10 falls through the hollow blanking heating tube 43, in the falling process, the hollow blanking heating tube 43 transfers heat to the metal nut 10, the temperature of the metal nut 10 entering the mounting hole of the plastic strip 20 rises, the plastic part on the side wall of the mounting hole is melted, and the metal nut 10 is adhered and fixed on the inner wall of the mounting hole, so that the operations of feeding and hot melting and fixing the metal nut 10 are completed.

The working principle of the blanking control mechanism 45 is as follows: the transverse pushing driving cylinder 451 provides a transverse driving force to drive the guide plate 452 to transversely and linearly slide along the slide rail 453, so that the connecting block 455 drives the blanking control block 456 to slide in the transverse movable cavity 422, and the blanking port 4561 on the blanking control block 456 is switched between being aligned with the longitudinal blanking cavity 421 and being away from the longitudinal blanking cavity 421. Specifically, as shown in fig. 3, in an initial state, the blanking port 4561 is staggered from the longitudinal blanking cavity 421, and the metal nut 10 cannot fall from the blanking port 4561 and enter the hollow blanking heating tube 43; when the blanking control block 456 slides leftwards to align the blanking opening 4561 with the longitudinal blanking cavity 421, as shown in fig. 4, the metal nut 10 can fall from the blanking opening 4561 into the hollow blanking heating tube 43; when the blanking control block 456 slides backward to the right so that the blanking opening 4561 is offset from the longitudinal blanking chamber 421, the metal nut 10 cannot fall from the blanking opening 4561 into the hollow blanking heat-generating tube 43, as shown in fig. 3.

In the present embodiment, the metal nuts 10 are dropped and loaded by controlling the drop control block 456 to slide left and right, so that the metal nuts 10 are sequentially dropped and loaded onto the plastic strip one by one.

When the metal nut 10 falls through the blanking port 4561, the lifting push cylinder 441 provides downward driving force to drive the nut positioning thin rod 442 to move downwards to enter the longitudinal blanking cavity 421 and closely follow the back of the metal nut 10, so that the next metal nut is blocked, and the next metal nut is prevented from falling along with the previous metal nut; when the metal nut 10 enters the plastic strip 20 on the carrying disc 2 through the hollow blanking heating tube 43, the nut positioning thin rod 442 also passes through the blanking port 4561, finally penetrates out the hollow blanking heating tube 43, is inserted into the central hole of the metal nut 10, and positions the metal nut 10, so that the metal nut 10 can be accurately adhered and fixed in the mounting hole of the plastic strip 20, and therefore the accuracy of the position of the metal nut 10 in feeding and hot melting fixing of the plastic strip 20 is improved.

In order to make the hollow blanking heating tube 43 generate heat and transmit the temperature to the metal nut 10, the hollow blanking heating tube 43 is connected with a plurality of heating wires 46 in the embodiment. In order to facilitate the hollow blanking heating tube 43 to smoothly transfer heat to the metal nut 10, preferably, the hollow blanking heating tube 43 is made of a metal material. Meanwhile, it should be noted that, since the plastic can be partially melted by heating, as long as the metal nut 10 has heat higher than normal temperature, the plastic on the inner wall of the mounting hole of the plastic strip 20 can be partially melted, and as long as the plastic is partially and slightly melted, the metal nut 10 can be stuck and fixed.

In the embodiment, the metal nuts 10 which are fed into the plastic strip 20 are adhered and fixed in a hot melting mode, so that the metal nuts 10 are prevented from being displaced, and the product quality is guaranteed.
