Description

Technical Field

[0001] The present invention relates to the technical field of palletizing and depalletizing devices, and particularly to an automatic paper bag feeding device. Background Art

[0002] Paper bags are a common and environmentally friendly packaging tool, and are widely used in various packaging and carrying needs due to their recyclability and the characteristics of reducing environmental pollution. During the production process of paper bags, it is crucial to ensure the accurate separation and smooth feeding of paper bags.

[0003] Chinese Patent Publication No. 202221516005.6, "An Automatic Paper Bag Feeding Device", includes: a conveying device, a resisting component, and a transmission component. The conveying device is used to convey stacked paper bags; the resisting component is located at the output end of the conveying device and forms a separation gap for a single paper bag to pass through between it and the conveying device; the transmission component includes a first roller shaft and a second roller shaft; the first roller shaft is installed above the second roller shaft and the two are arranged in parallel. There is a conveying gap between the first roller shaft and the second roller shaft, and their rotation directions are opposite; the paper bag coming out of the separation gap is output through the conveying gap.

[0004] Although this device can replace manual labor to feed the stacked paper bags into the next process, during the depalletizing of paper bags, due to factors such as static electricity, moisture, or adhesion between paper bags, multiple paper bags may fall together, easily causing machine jams, thereby affecting the efficiency and accuracy of feeding. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic paper bag feeding device, which solves the problem that in the existing device during the depalletizing process, due to the mutual adsorption between paper bags, the feeding efficiency and accuracy are affected.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An automatic paper bag feeding device, including a support frame, a top cover located above the support frame, and a lifting frame located inside the support frame for supporting paper bags, and further includes:

[0007] A depalletizing mechanism, including a lifting component, a vibration component, and a suction cup. A support plate is installed on the upper end surface of the suction cup. Fourth round rods are symmetrically and fixedly installed on both sides of the support plate. A fixed block is fixedly installed on the side of the fourth round rod away from the support plate. The outer wall of the fixed block is slidably installed on the support frame through a first chute opened on the support frame; the lifting component drives the paper bag at the top of the paper bag stack to rise through the suction cup. At this time, the vibration component drives the suction cup to vibrate through the support plate, reducing the adhesion between paper bags and preventing multiple paper bags from being adsorbed together;

[0008] The vibration assembly includes a plurality of extrusion blocks symmetrically installed on the outer wall of the support frame and fifth chutes symmetrically opened on the outer wall of the fourth round rod. A knocking rod is slidably installed on the inner wall of the fifth chute. A tension spring and a second sliding rod are respectively installed on both sides of the knocking rod. The side of the tension spring away from the knocking rod is installed on the support plate. One side of the second sliding rod penetrates through the fourth round rod and the fixed block to install a fixed frame. The third round rod is slidably installed on both sides of the fixed frame. When the third round rod extrudes the extrusion block, the third round rod stretches the tension spring through the fixed frame and the second sliding rod. When the third round rod does not extrude the extrusion block, the tension spring contracts, driving the knocking rod to knock the support plate, and the support plate drives the suction cup to vibrate.

[0009] Preferably, the lifting assembly includes an electric telescopic rod. The upper end surface of the electric telescopic rod is installed on the top cover, and the lower end surface of the electric telescopic rod is installed with a fixing plate. The fixing plate is symmetrically installed with sliding plates at the lower end surface. The outer wall of the sliding plate is provided with a fourth chute. Both sides of the sliding plate are slidably installed on the support frame through the second chute opened on the support frame. The inner wall of the fourth chute is slidably connected with the fourth round rod.

[0010] Preferably, the outer wall of the fixed frame is provided with a third chute. A second round rod is slidably installed on the inner wall of the third chute. A first sliding rod is installed on the side of the second round rod close to the support frame. Second magnets are symmetrically installed on the outer wall of the first sliding rod. A first magnet is installed on the side of the third round rod facing the second magnet. The opposite surfaces of the first magnet and the second magnet are of the same polarity.

[0011] Preferably, springs are symmetrically installed on the outer wall of the second round rod. A first round rod is installed on the side of the spring away from the second round rod. The first round rod is rotatably installed on the outer wall of the fixed frame.

[0012] Preferably, a first extrusion rod and a second extrusion rod are symmetrically installed on the outer wall of the support frame.

[0013] Preferably, a baffle is installed on the inner wall of the support frame.

[0014] Preferably, an inclined plate is installed on the inner wall of the support frame.

[0015] Preferably, the first sliding rod is made of iron material.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] The present invention is provided with a palletizing and depalletizing mechanism. After the suction cup adsorbs the paper bag, the electric telescopic rod contracts. The electric telescopic rod drives the sliding plate to slide upward in the second chute through the fixed plate. The sliding plate drives the fixed block to move upward in the first chute through the fourth chute and the fourth round rod. The fixed block and the fourth round rod drive the second sliding rod and the fixed frame to move. Since the second magnet is flush with the first magnet at this time and like poles repel each other, the third round rod extends outward at this time. While the fixed frame moves upward, the third round rod presses the extrusion block. At this time, the third round rod stretches the tension spring through the fixed frame and the second sliding rod, and the second sliding rod drives the knocking rod away from the support plate. When the third round rod does not press the extrusion block, the tension spring contracts, driving the second sliding rod and the knocking rod to move toward the support plate side. The knocking rod will knock the support plate. At this time, the support plate will cause the suction cup to vibrate slightly, vibrating the adsorbed paper bag. If there is a paper bag adsorbed below the paper bag adsorbed by the suction cup due to some factors at this time, the vibration will reduce the adhesion between the paper bags, causing the lower paper bag to fall, avoiding multiple paper bags being adsorbed together.

Detailed implementation mode

[0026] Please refer to Figures 1 to 7 , the present invention provides a technical solution: an automatic paper bag feeding device, including a support frame 2, a top cover 1 located above the support frame 2, and a lifting frame 12 located inside the support frame 2 for supporting paper bags, and further including:

[0027] A palletizing and depalletizing mechanism, including a lifting component, a vibration 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 and 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 a first chute 4 opened 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, reducing the adhesion between paper bags and preventing multiple paper bags from being adsorbed 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 chute 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 chute 29. A tension spring 30 and a second sliding rod 31 are respectively installed on both sides of the knocking rod 28. One side of the tension spring 30 away from the knocking rod 28 is installed on the support plate 23. One side of the second sliding rod 31 penetrates through the fourth round rod 27 and the fixing block 26 to install a fixing frame 13. Third round rods 18 are slidably installed on both sides of the fixing frame 13; when the third round rod 18 presses the extrusion block 6, the third round rod 18 stretches the tension spring 30 through the fixing frame 13 and the second sliding rod 31. When the third round rod 18 does not press the extrusion block 6, the tension spring 30 contracts, driving the knocking rod 28 to knock the support plate 23, and the support plate 23 drives the suction cup 25 to generate vibration.

[0029] Further, as shown in Figure 2 and Figure 5 , the lifting component 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 sliding plates 10. A fourth chute 24 is opened on the outer wall of the sliding plate 10. The sliding plates 10 are slidably installed on the support frame 2 through second chutes 8 opened on the support frame 2. The inner wall of the fourth chute 24 is slidably connected with the fourth round rod 27;

[0030] When the electric telescopic rod 7 extends or contracts, it drives the fixing plate 9 to move. The fixing plate 9 drives the sliding plate 10 to move in the second chute 8. The sliding plate 10 drives the fourth round rod 27 to move through the fourth chute 24;

[0031] Further, as shown in 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. At this time, the fixed block 26 returns along the original path in the first chute 4. Since the first magnet 21 on the third round rod 18 is adsorbed on the first slide rod 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 position in the first chute 4, the second extrusion rod 19 will squeeze the first slide rod 15, and the first slide rod 15 drives the second round rod 16 and the second magnet 22 to rise. When the second round rod 16 is above the first round rod 14, the spring 17 will hold against the second round rod 16, and the second round rod 16 prevents the first slide rod 15 from moving down. And at this time, the second magnet 22 is aligned with the first magnet 21. Due to the repulsion between like poles, the third round rod 18 extends outwards again, and at the same time, the suction cup 25 completes the adsorption of the paper bag. During this process, the lifting frame 12 will lift and lower to keep the paper bag always below the suction cup 25.
