[0047] The working principle of a sewing machine's alternating plate loading and unloading device according to an embodiment of this utility model is as follows:

[0048] S1: The operator loads materials onto the first loading / unloading plate 2;

[0049] S2: The lifting and transporting mechanisms 5 at both ends of the second upper and lower material plates 3 are activated. The lifting drive cylinder 51 of the lifting and transporting mechanism 5 drives the lifting seat 53 to slide upward along the direction of the third slide rail slider assembly 52, so that the second upper and lower material plates 3 rise. The synchronous wheel and synchronous belt drive assembly 61 of the second linear transport mechanism 6 drives the second sliding seat 63 to slide forward along the direction of the second slide rail slider assembly 62, so that the second upper and lower material plates 3 are moved to the top of the first upper and lower material plates 2.

[0050] S3: the pressing plate mechanism 7 pressed on the first upper and lower feeding plate 2 is lifted, wherein the telescopic drive cylinder 71 is extended, so that the rotating rod 72 is lifted by a certain angle, then the anti-falling drive cylinder 731 of the anti-falling module drives the anti-falling stopper 732 to extend, so that the anti-falling stopper 732 stops the rotating rod 72, to avoid the sudden falling of the rotating rod 72, and at the same time, a certain supporting force is given to the rotating rod 72;

[0051] S4: the first linear conveying mechanism 4 below the first upper and lower feeding plate 2 is actuated, the first linear drive cylinder 41 of the first linear conveying mechanism 4 drives the cylinder rod to move backward, so that the cylinder rod carries the connecting rod assembly 21 to move backward along the direction of the first slide rail slide block assembly 42, so that the first upper and lower feeding plate 2 comes to the position before the second upper and lower feeding plate 3, so that the first upper and lower feeding plate 2 is supplied to the sewing machine conveying mechanism of the prior art for feeding operation, and the next unloading operation is performed;

[0052] S5: the lifting drive cylinder 51 of the lifting conveying mechanism 5 drives the lifting seat 53 to slide downward along the direction of the third slide rail slide block assembly 52, so that the second upper and lower feeding plate 3 is lowered, so that the second upper and lower feeding plate 3 comes to the position before the first upper and lower feeding plate 2, and finally the second upper and lower feeding plate 3 realizes the next feeding operation;

[0053] S6: therefore, the first upper and lower feeding plate 2 and the second upper and lower feeding plate 3 reciprocate alternately to perform S1-S5 repeatedly, so that the first upper and lower feeding plate 2 and the second upper and lower feeding plate 3 reciprocate alternately to replace and switch the feeding and unloading operations.

[0054] In summary, the alternating plate replacing and feeding and unloading device of the sewing machine of the embodiment of the present application has the advantages that: through the reciprocating and alternating replacement of the first upper and lower feeding plate 2 and the second upper and lower feeding plate 3, the feeding and unloading of the two are realized, so that the operator can stand at the same position to feed and unload, avoiding the walking between feeding and unloading, so as to facilitate the feeding and unloading operation of the operator and reduce the labor intensity of the operator.

[0055] The above is only the preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
