[0017] The present invention is provided with a destacking mechanism. After the suction cup absorbs the paper bag, the electric telescopic rod is retracted, and the electric telescopic rod drives the slide plate to slide upward in the second slide slot through the fixed plate, and the slide plate drives the fixed block to move upward in the first slide slot through the fourth slide slot and the fourth round rod, and the fixed block and the fourth round rod drive the second slide bar and the fixed frame to move. Because the second magnet is flush with the first magnet at this time and repel each other with the same charge, the third round rod extends outward at this time, and while the fixed frame moves upward, the third round rod squeezes the squeezing block. At this time, the third round rod stretches the tension spring through the fixed frame and the second slide bar, and the second slide bar drives the knocking rod away from the supporting plate. When the third round rod does not squeeze the squeezing block, the tension spring contracts, driving the second slide bar and the knocking rod to move to one side of the supporting plate, and the knocking rod will knock the supporting plate. At this time, the supporting plate will cause the suction cup to vibrate slightly, causing the absorbed paper bag to vibrate. If a paper bag is absorbed under the paper bag absorbed by the suction cup due to some factors at this time, the vibration will reduce the adhesion between the paper bags, thereby causing the paper bags below to fall off, thereby preventing multiple paper bags from being absorbed together.

[0027] The destacking mechanism includes a lifting component, a vibrating component and a suction cup 25. A support plate 23 is installed on the upper end surface of the suction cup 25. Fourth round rods 27 are symmetrically fixedly installed on both sides of the support plate 23. A fixing block 26 is fixedly installed on the side of the fourth round rod 27 away from the support plate 23. The outer wall of the fixing block 26 is slidably installed on the support frame 2 through the first slide groove 4 provided on the support frame 2; the lifting component drives the paper bag at the top of the paper bag stack to rise through the suction cup 25. At this time, the vibration component drives the suction cup 25 to vibrate through the support plate 23, so that the adhesion between the paper bags is reduced to prevent multiple paper bags from being sucked together;

[0028] The vibration component includes a plurality of extrusion blocks 6 symmetrically installed on the outer wall of the support frame 2 and a fifth slide groove 29 symmetrically opened on the outer wall of the fourth round rod 27, a knocking rod 28 is slidably installed on the inner wall of the fifth slide groove 29, and a tension spring 30 and a second slide rod 31 are respectively installed on both sides of the knocking rod 28, the tension spring 30 is installed on the support plate 23 away from the knocking rod 28, and a fixed frame 13 is installed on one side of the second slide rod 31 that passes through the fourth round rod 27 and the fixed block 26, and a third round rod 18 is slidably installed on both sides of the fixed frame 13; when the third round rod 18 squeezes the extrusion block 6, the third round rod 18 stretches the tension spring 30 through the fixed frame 13 and the second slide rod 31, and when the third round rod 18 does not squeeze the extrusion block 6, the tension spring 30 contracts, driving the knocking rod 28 to knock on the support plate 23, and the support plate 23 drives the suction cup 25 to vibrate.

[0029] Further, such as Figure 2 and Figure 5 As shown, the lifting assembly includes an electric telescopic rod 7, the upper end surface of the electric telescopic rod 7 is installed on the top cover 1, the lower end surface of the electric telescopic rod 7 is installed with a fixing plate 9, the lower end surface of the fixing plate 9 is symmetrically installed with a slide plate 10, the outer wall of the slide plate 10 is provided with a fourth slide groove 24, both sides of the slide plate 10 are slidably installed on the support frame 2 through the second slide groove 8 provided on the support frame 2, and the inner wall of the fourth slide groove 24 is slidably connected with the fourth round rod 27;

[0030] When the electric telescopic rod 7 is extended or retracted, it drives the fixed plate 9 to move, and the fixed plate 9 drives the slide plate 10 to move in the second slide groove 8, and the slide plate 10 drives the fourth round rod 27 to move through the fourth slide groove 24;

[0031] Further, such as Figure 3 and Figure 4As shown, the outer wall of the fixed frame 13 is provided with a third slide groove 20, the inner wall of the third slide groove 20 is slidably mounted with a second round rod 16, the second round rod 16 is mounted with a first slide rod 15 on the side close to the support frame 2, the outer wall of the first slide rod 15 is symmetrically mounted with a second magnet 22, the third round rod 18 is mounted with a first magnet 21 on the side facing the second magnet 22, and the opposite surfaces of the first magnet 21 and the second magnet 22 are of the same polarity;

[0032] When the first slide bar 15 moves up and down in the fixed frame 13, it drives the second round bar 16 to move in the third slide groove 20. At the same time, the first slide bar 15 drives the second magnet 22 to move. When the second magnet 22 is flush with the first magnet 21, due to like charges repelling each other, the first magnet 21 drives the third round bar 18 away from the first slide bar 15. When the second magnet 22 is staggered with the first magnet 21, the first magnet 21 attracts the first slide bar 15. At this time, the third round bar 18 moves to the side close to the first slide bar 15.

[0033] Furthermore, a spring 17 is symmetrically mounted on the outer wall of the second round rod 16, and a first round rod 14 is mounted on the side of the spring 17 away from the second round rod 16, and the first round rod 14 is rotatably mounted on the outer wall of the fixed frame 13;

[0034] When the second round rod 16 is located on the upper side or the lower side of the first round rod 14, the spring 17 is extended to support the second round rod 16 to prevent the second round rod 16 from moving;

[0035] Further, such as Figure 5 As shown, the outer wall of the support frame 2 is symmetrically mounted with a first extrusion rod 5 and a second extrusion rod 19;

[0036] The first extrusion rod 5 and the second extrusion rod 19 squeeze the first sliding rod 15;

[0037] Further, such as Figure 2 As shown, a baffle 11 is installed on the inner wall of the support frame 2;

[0038] One side of the paper bag stack is against the baffle 11;

[0039] Further, such as Figure 1 As shown, an inclined plate 3 is installed on the inner wall of the support frame 2;

[0040] The paper bag slides down from the inclined plate 3 and enters the next process;

[0041] Furthermore, the first slide bar 15 is made of iron material;

[0042] The first magnet 21 will attract the first slide bar 15 , thereby driving the third round rod 18 to move toward the first slide bar 15 .

[0043] Working principle: Step 1: After connecting the external power supply and controller, place the paper bag stack on the lifting frame 12 (existing technology). After the suction cup 25 absorbs the paper bag, control the electric telescopic rod 7 to retract. The electric telescopic rod 7 drives the slide plate 10 to slide upward in the second slide groove 8 through the fixed plate 9. The slide plate 10 drives the fixed block 26 to move upward in the first slide groove 4 through the fourth slide groove 24 and the fourth round rod 27. The fixed block 26 and the fourth round rod 27 drive the second slide bar 31 and the fixed frame 13 to move. At this time, since the second magnet 22 is flush with the first magnet 21 and the same charges repel each other, the third round rod 18 extends outward at this time. While the fixed frame 13 moves upward, the third round rod 18 squeezes The squeezing block 6 is pressed, and the third round rod 18 stretches the tension spring 30 through the fixed frame 13 and the second sliding rod 31, and the second sliding rod 31 drives the knocking rod 28 away from the support plate 23. When the third round rod 18 does not squeeze the squeezing block 6, the tension spring 30 contracts, driving the second sliding rod 31 and the knocking rod 28 to move toward the side of the support plate 23, and the knocking rod 28 knocks the support plate 23. At this time, the support plate 23 causes the suction cup 25 to vibrate slightly, causing the adsorbed paper bag to vibrate. If there is a paper bag adsorbed under the paper bag adsorbed by the suction cup 25 due to some factors, the vibration will reduce the adhesion between the paper bags, so that the paper bag below falls on the paper bag pile, avoiding multiple paper bags from being adsorbed together;

[0044] Step 2: When the fixed block 26 moves to the bottom of the first extrusion rod 5, the first extrusion rod 5 will squeeze the first slide bar 15, and the first slide bar 15 will drive the second round rod 16 to move downward in the third slide groove 20, and the second round rod 16 will drive the spring 17 to rotate with the first round rod 14 as the center of the circle. At this time, the spring 17 is compressed. When the second round rod 16 is located below the first round rod 14, the spring 17 stretches out and will support the second round rod 16. The second round rod 16 will prevent the first slide bar 15 from moving up. Since the first slide bar 15 is made of iron material, and the first slide bar 15 moves downward and drives the second magnet 22 to descend, at this time, the second magnet 22 is staggered with the first magnet 21, and the first magnet 21 will be adsorbed inward on the first slide bar 15;

[0045] Step 3: As the slide plate 10 rises, the fourth chute 24 drives the fixed block 26 to move horizontally in the first chute 4 through the fourth round rod 27. When the suction cup 25 is located above the inclined plate 3, the suction cup 25 stops sucking the paper bag, and the paper bag falls above the inclined plate 3 and enters the next process.

[0046] Step 4: After the paper bag enters the next process, the electric telescopic rod 7 descends, and the fixed block 26 returns to the original path in the first slide groove 4. Since the first magnet 21 on the third round rod 18 is adsorbed on the first slide bar 15 at this time, the third round rod 18 will not be blocked by the extrusion block 6. When the fixed block 26 moves to the lowest point in the first slide groove 4, the second extrusion rod 19 will squeeze the first slide bar 15, and the first slide bar 15 drives the second round rod 16 and the second magnet 22 to rise. When the second round rod 16 is located above the first round rod 14, the spring 17 will support the second round rod 16, and the second round rod 16 prevents the first slide bar 15 from moving downward, and at this time the second magnet 22 is aligned with the first magnet 21. Due to the repulsion of like charges, the third round rod 18 extends outward again at this time, and the suction cup 25 completes the adsorption of the paper bag. During this process, the lifting frame 12 will be lifted and lowered so that the paper bag is always located below the suction cup 25.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
