[0045] Embodiment 5: Figure 1 and 2 As shown, a transplanting mechanism for loading and unloading a knurling machine disclosed in the fifth embodiment of the utility model has a structure that is basically the same as that in the first embodiment, except that a second guide rail 5 is installed on the surface of the support frame 101 outside the first connecting block 102, a fourth sliding block 501 is installed on the surface of the second guide rail 5, and the surface of the fourth sliding block 501 is connected to the inner cavity of the first sliding block 2;

[0047] Example 6: Figure 1 , 2 , 3 and 6, a transplanting mechanism for loading and unloading a knurling machine disclosed in the sixth embodiment of the utility model has a structure that is basically the same as that in the second embodiment, except that a downward pressure cylinder 6 is installed on the surface of the third connecting plate 209, a pressing plate 601 is installed at one end of the output rod of the downward pressure cylinder 6, a fifth connecting plate 602 is installed at the top end of the third connecting plate 209, a second spring 603 is installed at the bottom end of the fifth connecting plate 602, a first supporting plate 604 is installed at the bottom end of the third connecting plate 209, the top end of the first supporting plate 604 is fitted with the bottom end of the fourth connecting plate 301, a second supporting plate 605 is installed at the bottom end of the third connecting plate 209 outside the first supporting plate 604, a connecting column 606 is installed in the inner cavity of the second supporting plate 605, a telescopic column 607 is installed in the inner cavity of the connecting column 606, a rubber block 608 is installed at one end of the telescopic column 607, and one end of the rubber block 608 is fitted with the bottom end of the fourth connecting plate 301;

[0048] By setting the downward pressing cylinder 6 and starting the downward pressing cylinder 6, the output rod of the downward pressing cylinder 6 drives the pressing plate 601 to move downward. Since the connecting shaft 3 is connected between the third connecting plate 209 and the fourth connecting plate 301, when the pressing plate 601 moves downward, the fourth connecting plate 301 can be adjusted downward in angle. Since the fourth connecting plate 301 is adjusted downward in angle, the fourth connecting plate 301 can drive the second spring 603 to extend and squeeze the rubber block 608 to shrink the telescopic column 607. At this time, when the transplanting mechanism is conveying the product for knurling, the product can be obliquely knurled. When the oblique knurling is completed, the output rod of the downward pressing cylinder 6 shrinks and returns to its original position. At this time, the telescopic column 607 starts to extend and the second spring 603 shrinks, driving the fourth connecting plate 301 to its original position.

[0049] By providing the first support plate 604 , when the bottom end of the fourth connecting plate 301 is in contact with the top end of the first support plate 604 , it means that the fourth connecting plate 301 has returned to its original position and is in a horizontal state.

[0050] Embodiment 7: Figure 1 As shown, a transplanting mechanism for loading and unloading a knurling machine disclosed in the seventh embodiment of the present utility model has a structure that is basically the same as that in the fifth embodiment, except that a third support plate 7 is installed on the surface of the support frame 101 outside the second guide rail 5, and a drive motor 701 is installed on one side of the third support plate 7 and one end of the second screw rod 202;

[0051] By providing a driving motor 701 , the driving motor 701 is mainly used to drive the first screw rod 103 and the second screw rod 202 to rotate.

[0052] Embodiment 8: Figure 1As shown, the structure of a transplanting mechanism for loading and unloading a knurling machine disclosed in the eighth embodiment of the present utility model is basically the same as that in the seventh embodiment, except that the driving motor 701 is connected to the first screw rod 103 by means of a coupling 8;

[0053] By setting the coupling 8, the coupling 8 is mainly used to transmit torque and power, compensate for shaft centering errors, reduce vibration and absorb impact, and protect against overload.

[0054] The specific scheme is as follows: first, the drive motor 701 is started to drive the first screw rod 103 to rotate, so that the transplanting component moves to the feeding mechanism, and then the drive motor 701 is started again to rotate the second screw rod 202. The rotation of the second screw rod 202 can drive the second sliding block 203 to move up and down. The lifting of the second sliding block 203 can drive the first connecting plate 204, the second connecting plate 205, the third connecting plate 209 and the fourth connecting plate 301 to move up and down, thereby driving the clamping cylinder 303, the supporting cylinder 304, the clamping claw 403 and the supporting claw 404 to move up and down, so that the clamping claw 403 and the supporting claw 404 move to the feeding mechanism, clamp the product from the feeding mechanism, and after clamping the outer side, the second screw rod 202 is reversed to make the transplanting component The parts will return to their original positions, and the first screw rod 103 will be rotated again at this time, so that the transplanting part will transfer the product to the knurling machine, so that the knurling machine will knurl the product. After the knurling is completed, the second screw rod 202 will rotate again, so that the transplanting part will drive the product away from the knurling machine. At this time, the slide cylinder 206 will be started, and the output rod of the slide cylinder 206 can drive the third connecting plate 209, the fourth connecting plate 301, the clamping cylinder 303, the supporting cylinder 304, the clamping claw 403 and the supporting claw 404 to move forward. At this time, the second screw rod 202 will be started again, driving the clamping claw 403 and the supporting claw 404 to move downward, so that the product is above the unloading mechanism. At this time, the clamping claw 403 and the supporting claw 404 are loosened, and the product can fall into the unloading mechanism. When oblique knurling is required, the pressing cylinder 6 is moved, and the output rod of the pressing cylinder 6 drives the pressing plate 601 to move downward. Since the connecting shaft 3 is connected between the third connecting plate 209 and the fourth connecting plate 301, when the pressing plate 601 moves downward, the fourth connecting plate 301 can be adjusted downward in angle. Since the fourth connecting plate 301 is adjusted downward in angle, the fourth connecting plate 301 will drive the second spring 603 to extend and squeeze the rubber block 608 to shrink the telescopic column 607. At this time, the transplanting mechanism can perform oblique knurling on the product when conveying the product for knurling. When the oblique knurling is completed, the output rod of the pressing cylinder 6 shrinks and returns to its original position. At this time, the telescopic column 607 begins to extend and the second spring 603 shrinks, driving the fourth connecting plate 301 to When the clamping claw 403 or the supporting claw 404 needs to be installed, the inner cavity of the clamping claw 403 or the supporting claw 404 is first aligned with the surface of the second connecting block 402, so that the second connecting block 402 enters into the inner cavity of the clamping claw 403 or the supporting claw 404, and the second connecting block 402 is squeezed upward to shrink the first spring 401. During the rising process of the second connecting block 402,When the inner cavity of the second connecting block 402 is aligned with the inner cavity of the limiting block 4, the fixing pin 405 is inserted, so that the fixing pin 405 can fix the clamping claw 403 or the supporting claw 404.
