[0001] The utility model belongs to the technical field of bag-opening equipment, and in particular relates to a high-efficiency full-automatic bag-opening machine. Background Art

[0002] During the production and processing process, products often need to be bagged to facilitate packaging. There are generally two ways to open the packaging bags on the production line: one is pure manual operation, that is, manually opening the bag mouth for loading, which is time-consuming and labor-intensive; the other is to use machinery to control the bag opening and bagging by machinery, which is highly efficient.

[0003] However, most existing bag-opening mechanisms can only open packaging bags of a specific size and cannot adjust the opening range according to the size of the packaging bag, which may cause the packaging bag to break or not be fully opened, so that the product to be packaged cannot be accurately filled into the packaging bag during filling, affecting packaging efficiency. At the same time, the existing bag-opening mechanism is not convenient for fully automatic operation. After the bag is filled, the bag-opening mechanism is retracted, and the packaging bag needs to be transferred to the next process through manual or subsequent operations, which increases manual operations and reduces production efficiency.

One side of the block 22 is connected to the outside of the first screw 20 through a threaded transmission and the other side is sleeved on the outside of the first limiting rod 21. The first limiting rod 21 can limit the first screw slider 22.

On the upper surface of the bag body, the bag-taking suction cup 25 is connected to the external air path, which enables it to suck the bag body, and then retract the movable end of the fourth double-axis cylinder 24 to suck up the bag body, and then retract the movable end of the third double-axis cylinder 23 to move the bag body a short distance into the operating table 1, and then control the first motor 19 to operate and drive the first screw 20 to rotate in the opposite direction, so that the first screw slider 22 moves in the direction away from the bag body placement structure, and can move the bag body to the top of the placement plate 4 and make the bag body correspond to the suction hole 6, and finally control the movable end of the fourth double-axis cylinder 24 to press down to place the bag body on the placement plate 4;

[0031] On one side of the operating table 1 close to the bag taking and placing structure, there is a bag placing structure, and the bag taking and placing structure is arranged above the bag placing structure.

The second limiting rod 36 is fixedly connected between the two support rods 7 on the side close to the second lead screw 33. The arc-shaped sleeve 35 is fixedly connected to the side of the second lead screw slider 34 close to the rectangular rod 31. One side of the second lead screw slider 34 is threadedly connected to the outside of the second lead screw 33 and the other side is sleeved on the outside of the second limiting rod 36. The second limiting rod 36 can limit the movement of the second lead screw slider 34, making it only move back and forth along the direction of the second limiting rod 36. The third motor 32 drives the second lead screw 33 to rotate, which can drive the second lead screw slider 34 to move horizontally;

The cylinder body of the fifth double-axis cylinder 39 is fixedly connected to the side of the sliding block 37 and the first bracket 40 is fixedly connected to the outside of the cylinder body of the fifth double-axis cylinder 39. Both sides of the inside of the first bracket 40 are rotatably connected to the bag-supporting arms 41 and the middle parts of the two bag-supporting arms 41 are rotatably connected to the first connecting rod 42. The ends of the two first connecting rods 42 that are close to each other are rotatably connected to the movable rod body part of the fifth double-axis cylinder 39. The movable end of the fifth double-axis cylinder 39 is retracted inwardly to drive the bag-supporting arms 41 on both sides to approach each other through the two first connecting rods 42, thereby adjusting the second The opening width of the bag-holding structure; the bag-holding arms 41 and the first connecting rod 42 on both sides are symmetrically arranged with the vertical midline of the first bracket 40 as the symmetry axis, and the second bag-holding structure includes a second bracket 43, a second connecting rod 44, a bag-holding clamp 45 and an adjusting rod 46. The two bag-holding arms 41 are fixedly mounted with the second bracket 43 at one end away from the first bracket 40, and the second connecting rod 44 is rotatably connected to the bag-holding clamp 45 on both sides of the second bracket 43, and the two second connecting rods 44 are rotatably connected to the bag-holding clamp 45 at one end away from the second bracket 43.

The two ends of the internally threaded tube are threadedly connected to the threaded rods, and the two threaded rods are rotatably connected to the inside of the bag-holding clamps 45 on both sides. By rotating the internally threaded tube, the overall length of the adjusting rod 46 can be adjusted, thereby adjusting the opening distance of the two bag-holding clamps 45, so that the bag-holding clamps 45 can be adjusted according to the size of the bag body, so as to be used when holding bags of different sizes;

[0034] The third motor 32 drives the second lead screw 33 to rotate, thereby driving the second lead screw slider 34 to move toward the side of the bag body that has been opened by the upper and lower suction cup structures. Since the arc sleeve 35 on the side of the second lead screw slider 34 is engaged with the clamping plate 38 on the sliding block 37, it can drive the first bag-holding structure and the second bag-holding structure to move synchronously to the position corresponding to the bag body. Then, the second motor 30 is controlled to operate to drive the rectangular rod 31 to rotate ninety degrees counterclockwise, so that the second bag-holding structure can be inserted into the bag body whose opening has been opened, thereby opening the upper and lower parts of the bag body. Then, the fifth dual-axis cylinder 39 is controlled to push the movable rod part outward, so that the bag-holding arms 41 on both sides move away from each other, so that the second bag-holding structures on both sides can open the left and right sides of the bag body. At this time, the bag body can be completely opened.

[0035] The first conveyor belt 2 and the second conveyor belt 3 are both arranged on the front side of the operating table 1. The first conveyor belt 2 and the second conveyor belt 3 are both well-known prior arts, so no further elaboration will be made here. The first conveyor belt 2 and the second conveyor belt 3 are arranged perpendicular to each other and the second conveyor belt 3 is higher than the first conveyor belt 2. At the position corresponding to the upper and lower suction cup structures on the top of the first conveyor belt 2, a pusher cylinder 47 is fixedly installed. The movable rod part of the pusher cylinder 47 is fixedly connected with a pusher plate 48. After the first bag-supporting structure and the second bag-supporting structure expand the bag body, the movable end of the pusher cylinder 47 extends outwards, and the material on the first conveyor belt 2 is pushed into the bag body through the pusher plate 48, thus completing the bagging work. Then, the upper suction cup 14 and the lower suction cup 18 lose suction. The second motor 30 drives the rectangular rod 31 to rotate clockwise by ninety degrees, which can make the first bag-supporting structure and the second bag-supporting structure drive the bag body filled with materials to rotate upwards and make the bag body in a state with the opening facing upwards. Then, control the third motor 32 to operate to drive the second lead screw 33 to rotate, so that the second lead screw slider 34 moves towards the direction close to the second conveyor belt 3, and can drive the sliding block 37 to slide on the rectangular rod 31 through the arc-shaped sleeve 35 and the clamping plate 38, so that the bag body moves onto the second conveyor belt 3. Then, control the movable rod part of the fifth double-shaft cylinder 39 to retract, so that the two bag-supporting arms 41 approach each other. Then, drive the rectangular rod 31 to continue to rotate clockwise by a small angle through the second motor 30, so that the second bag-supporting structure can be taken out from the bag body, and the bag body is transported to the next process under the action of the second conveyor belt 3;

Control the operation of the first motor 19 to drive the first lead screw slider 22 to move towards the bag placing structure through the first lead screw 20, so that the bag-taking suction cup 25 moves above the bag. Then, control the movable end of the fourth double-axis cylinder 24 to descend, so that the bag-taking suction cup 25 sucks the bag. Then, retract the movable end of the fourth double-axis cylinder 24 to lift the bag. Subsequently, control the first motor 19 to rotate in the reverse direction to drive the first lead screw 20 to rotate in the reverse direction, so that the first lead screw slider 22 moves away from the bag placing structure, and the bag can be moved above the placing plate 4 and the bag is aligned with the suction holes 6. Control the movable end of the fourth double-axis cylinder 24 to press down to place the bag on the placing plate 4, and then retract the bag-taking suction cup 25;

[0040] 3. The second double-axis cylinder 11 drives the upper fixing plate 12 to move downward, so that the upper suction cup 14 drops to tightly suck the upper part of the bag opening, and the lower suction cup 18 below tightly sucks the lower part of the bag opening. Then, drive the upper part of the bag opening to rise through the second double-axis cylinder 11, so as to open the bag opening.
