[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0029] Reference Figures 1 to 4 As shown, in one embodiment of the utility model, a paper bag sealing device comprises a lifting mechanism 1 and a mounting plate 2 arranged up and down, the lifting mechanism 1 drives the mounting plate 2 to rise and fall, a lifting plate 3 is arranged above the mounting plate 2, a first cylinder 4 is arranged on the lifting plate 3, the first cylinder 4 is connected to the mounting plate 2 to drive the lifting plate 3 to rise and fall, and the mounting plate 2 extends along the length direction of the paper bag;

[0030] The mounting plate 2 is provided with clamping plates 5 on both sides along its length direction, and the lower end of the clamping plates 5 is lower than the mounting plate 2. The lifting plate 3 is provided with a second cylinder 6, and the second cylinder 6 can drive the two clamping plates 5 to move in opposite directions;

[0031] A blocking mechanism 7 for blocking the tail of the paper bag is provided at one end of the mounting plate 2 along its length direction, and a sealing mechanism 8 for bending the reserved section of the paper bag is provided at the other end of the mounting plate 2 along its length direction;

[0032] Specifically, when a preset number of round covers are loaded into the paper bag, the lifting mechanism 1 will start to lower the mounting plate 2 to a preset position, and then the two clamping plates 5 will approach each other to hold the paper bag, and the lifting plate 3 will rise again to press the paper bag against the mounting plate 2, thereby completing the fixation of the paper bag. The lifting mechanism 1 will then lift the mounting plate 2 to empty the paper bag, and then the blocking mechanism 7 will start to block the tail of the paper bag to prevent the paper bag from moving when the reserved section of the paper bag is bent, and then the sealing mechanism 8 will bend the reserved section of the paper bag to complete the sealing. At this time, the sealed paper bag can be placed in other positions, and then the sealing of the next paper bag can be continued.

[0033] In this embodiment, the lower portion of the clamping plate 5 is bent in a direction close to the other clamping plate 5. Therefore, when the two clamping plates 5 are close to each other, the two clamping plates 5 can hold up the paper bag, thereby supporting the round cover in the paper bag and preventing the round cover in the paper bag from falling.

[0034] In this embodiment, there are two first cylinders 4 arranged at intervals along the extension direction of the mounting plate 2, which can stably drive the lifting plate 3 to rise and fall; there are also two second cylinders 6 arranged at intervals along the extension direction of the mounting plate 2, which can effectively drive the two clamping plates 5 to move.

[0035] In this embodiment, the blocking mechanism 7 includes a baffle 71 and a third cylinder 72 fixed on the mounting plate 2, and the third cylinder 72 drives the baffle 71 to move along the extension direction of the mounting plate 2;

[0036] When the paper bag is emptied, the third cylinder 72 is activated, and the baffle 71 approaches the mounting plate 2, thereby contacting the paper bag and pressing against the round cover inside the paper bag;

[0037] Preferably, a contoured groove for positioning the round covers in the paper bag is provided on one side of the baffle 71 close to the paper bag. After the baffle 71 is pressed onto the paper bag, the round cover at the rear end of the paper bag will be stuck in the contoured groove and will not move around. Since the round covers in the paper bag are stacked together, after the rear end of the round cover is stuck, the entire stack of round covers can be positioned and will not move around.

[0038] In this embodiment, the sealing mechanism 8 includes a push plate 81 and a fourth cylinder 82 fixed on the mounting plate 2, and the fourth cylinder 82 drives the push plate 81 to move along the extension direction of the mounting plate 2;

[0039] When the baffle 71 blocks the tail of the paper bag, the fourth cylinder 82 is started to move the push plate 81 close to the mounting plate 2, so that the push plate 81 bends the reserved section of the paper bag. At this time, the reserved section of the paper bag is bent 90 degrees, completing the first bend.

[0040] Specifically, the sealing mechanism 8 includes a roller 83, a fifth cylinder 84 and a sixth cylinder 85. The fifth cylinder 84 is connected to the mounting plate 2, and the sixth cylinder 85 is connected to the output end of the fifth cylinder 84. The fifth cylinder 84 drives the sixth cylinder 85 to move up and down. The roller 83 is connected to the output end of the sixth cylinder 85, and the sixth cylinder 85 drives the roller 83 to move along the extension direction of the mounting plate 2.

[0041] Before the action, the roller 83 is higher than the push plate 81 and is located on the side of the push plate 81 away from the mounting plate 2, ensuring that the roller 83, the fifth cylinder 84 and the sixth cylinder 85 do not interfere with the movement of the push plate 81;

[0042] After the push plate 81 completes the first bending of the reserved section of the paper bag, the fifth cylinder 84 operates first to drive the sixth cylinder 85 to descend, so that the roller 83 is lower than the push plate 81, and then the sixth cylinder 85 operates to make the roller 83 close to the mounting plate 2. The roller 83 presses the reserved section of the paper bag to bend 90 degrees again, completing the second bending. At this time, the reserved section of the paper bag can reach the bottom of the round cover pile, completing the sealing of the paper bag.

[0043] In this embodiment, the axis of the roller 83 is arranged horizontally, and the axis of the roller 83 is perpendicular to the extension direction of the mounting plate 2 .

[0044] In this embodiment, when the two clamping plates 5 hold the paper bag, the distance between the lower ends of the two clamping plates 5 should be greater than or equal to the length of the roller 83 to ensure that the roller 83 can roll the reserved section of the paper bag.

[0045] In this embodiment, the outer diameter of the roller 83 gradually increases from the middle to both ends, so that the roller 83 can adapt to the shape of the round cover. When the roller 83 rolls the reserved section of the paper bag, the reserved section can fit to the bottom of the paper bag.

[0046] In this embodiment, the lifting mechanism 1 is a screw-nut lifting assembly, which drives the screw to rotate through a servo motor, thereby driving the nut to move up and down, and the nut then drives the mounting plate 2 to move up and down, so that the height of the mounting plate 2 can be accurately controlled.

[0047] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate 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 claims and their equivalents.
