[0069] When in use, the operator puts the material into the storage hopper 41, and then starts the automatic unloading and canning packaging equipment. The material in the storage hopper 41 falls from the storage unloading port onto the vibration plate 42 under the action of its own gravity, and then the material on the vibration plate 42 continues to fall from the vibration unloading port onto the weighing mechanism 43 after vibration. When the material on the weighing mechanism 43 reaches a preset weight, the vibration plate 42 stops vibrating, and the weighing unloading port opens to allow the material to continue to fall into the discharge hopper 44 through the weighing unloading port. When the material on the weighing mechanism 43 does not reach the preset weight, the vibration plate 42 continues to vibrate, and the weighing unloading port is closed to prevent the material from continuing to fall into the discharge hopper 44 through the weighing unloading port.

[0078] In this embodiment, the press driver 452 adopts a linear cylinder, but those skilled in the art know that the press driver 452 in this case can also adopt other conventional power devices, such as motors and screws, etc. Therefore, the protection scope of this case should not be limited by the specific form of the press driver 452.

[0100] The first can clamping unit 611 includes a first sensor 613, and the first sensor 613 is used to sense the packaging can 6 conveyed to the first can clamping unit 611 on the can conveying device 3. When the first sensor 613 senses the packaging can 6, the first can clamping unit 611 clamps the sensed packaging can 6 to stop conveying it forward until the second can clamping unit 612 releases the previous packaging can 6.

[0101] The second can clamping unit 612 includes a second sensor 614, which is used to sense the packaging can 6 transported to the second can clamping unit 612 from the can feeding device 3. When the second sensor 614 senses the packaging can 6, the second can clamping unit 612 clamps the sensed packaging can 6 to stop forward conveyance until a predetermined time is reached.

[0102] When in use, when the second sensor 614 senses that the packaging can 6 on the can feeding device 3 is conveyed to the second can clamping unit 612, the second can clamping unit 612 clamps the sensed packaging can 6 to stop it from being conveyed forward to the various unloading positions of the unloading device 4 or the various sealing positions of the sealing device 5 until a predetermined time is reached, and then releases the packaging can 6 to continue to be conveyed forward. The clamping time of each packaging can 6 by the second can clamping unit 612 can be adjusted according to the can feeding speed of the can feeding device 3 and the required feeding speed. The required can delivery spacing is the spacing between each unloading position or the spacing between each sealing position; when the first sensor 613 senses that the packaging can 6 on the can delivery device 3 is conveyed to the first can clamping unit 611, the first can clamping unit 611 clamps the sensed packaging can 6 to stop it from being conveyed forward to avoid it from flowing into the second can clamping unit 612, until the second can clamping unit 612 releases the previous packaging can 6, and then releases the packaging can 6 to allow it to flow into the second can clamping unit 612.

[0103] The first can clamping unit 611 and the second can clamping unit 612 each include a can clamping bracket 615 and a can clamping claw 616. The can clamping bracket 615 has an opening upward, and the can feeding device 3 passes through the opening of the can clamping bracket 615 to convey the packaging can 6 forward; the can clamping claw 616 is arranged on both sides of the opening of the can clamping bracket 615, the first sensor 613 is arranged at the opening of the can clamping bracket 615 of the first can clamping unit 611, and the second sensor 614 is arranged at the opening of the can clamping bracket 615 of the second can clamping unit 612.

[0104] In this embodiment, the can clamping gripper 616 adopts a mechanical gripper, but those skilled in the art know that the can clamping gripper 616 in this case can also adopt other conventional grippers, such as a suction cup gripper, etc. Therefore, the protection scope of this case should not be limited by the specific form of the can clamping gripper 616.

[0105] The positioning mechanism 62 includes a front and rear positioning unit 621, a side positioning unit 622 and a height positioning unit 623.

[0106] The front-to-back positioning unit 621 is used to position the packaging can 6 in the front-to-back direction along its conveying direction, and includes two conveying blocks 6211 and a block driver connected to drive the two conveying blocks 6211 to move relative to each other. The two conveying blocks 6211 are respectively arranged on two sides perpendicular to the conveying direction of the packaging can 6. When the two conveying blocks 6211 are relatively close to each other, the distance between the two conveying blocks 6211 is smaller than the width of the packaging can 6, which can prevent the packaging can 6 from passing through and cannot be further conveyed forward. When the two conveying blocks 6211 are relatively far away from each other, the distance between the two conveying blocks 6211 is larger than the width of the packaging can 6, which can allow the packaging can 6 to pass through and continue to be conveyed forward.

[0107] The two side positioning units 622 are used to position the packaging cans 6 in the two side directions perpendicular to the conveying direction thereof, and are located on the side of the front and rear positioning units 621 facing the can sorting mechanism 61, and include two conveying clamps 6221 and a clamp driver connected to drive the two conveying clamps 6221 to move relative to each other. When the two conveying clamps 6221 are relatively close to each other, the two conveying clamps 6221 will jointly clamp the packaging cans 6 blocked by the front and rear positioning units 621; when the two conveying clamps 6221 are relatively far away from each other, the two conveying clamps 6221 will jointly release the packaging cans 6 blocked by the front and rear positioning units 621;

[0108] The height positioning unit 623 is used to position the packaging can 6 in the height direction, and is connected to the two side positioning units 622 to drive the two side positioning units 622 to move up and down, thereby driving the packaging can 6 clamped by the two side positioning units 622 to move up and down together, including a lifting platform and a can lifting driver connected to drive the lifting platform to move up and down, and the two side positioning units 622 are arranged on the lifting platform.

[0109] When in use, each packaging can 6 whose feeding spacing is adjusted by the can sorting mechanism 61 is simultaneously sent to the corresponding positioning mechanism 62 by the can feeding device 3. First, the two conveying blocks 6211 in the front and rear positioning units 621 are relatively close to each other to block the corresponding packaging can 6, so that it cannot continue to be conveyed forward and stops at the corresponding unloading position or sealing position. Then, the two conveying clamps 6221 in the two side positioning units 622 are relatively close to each other to clamp the corresponding packaging can 6 to prevent the packaging can 6 from shifting to the left and right sides. Then, the height positioning unit 623 drives the two side positioning units 622 together with the corresponding packaging can 6 to the required height. Finally, the unloading device 4 or the sealing device 5 unloads or seals the packaging can 6.

[0110] The positioning mechanism 62 includes a positioning bracket 624, which also has an opening upward. The can conveying device 3 passes through the opening of the positioning bracket 624 to convey the packaging can 6 forward; the conveying block 6211 and the conveying clamp 6221 are arranged on both sides of the opening of the positioning bracket 624, and the can lifting unit is arranged below the opening of the positioning bracket 624.

[0111] In this embodiment, the block driver, splint driver and tank lifting driver all use linear cylinders, but those skilled in the art know that the block driver, splint driver and tank lifting driver in this case may also use other conventional power devices, such as electrodes and screw rods, etc. Therefore, the protection scope of this case should not be limited by the specific forms of the block driver, splint driver and tank lifting driver.

[0112] The above-mentioned embodiments merely express the implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. Any technical solution obtained in the form of equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
