Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a box opening device used for forming a packaging box. Background Art

[0002] Gift boxes are divided into inner boxes and outer boxes, and sometimes they also have lids. The outer boxes are further divided into bottomless boxes and bottomed boxes. The bottomless boxes are rectangular or polygonal in shape, with a through-shaped accommodating cavity in the center, and the inner box is installed in the outer box in a pull-out manner; the bottomed boxes have a bottom composed of several folding tongues at the bottom, and the accommodating cavity is open at the top. The outer box needs to be opened when the gift box is processed and formed.

[0003] Publication No. CN216360054U discloses a gift packaging outer box opening machine. This patent utilizes a suction cup driven by a suction cup cylinder to suck sheet-shaped outer boxes in a receiving chamber one by one onto a workbench. In the suctioned state, a flap swings, and the flap cooperates with a limiting flange to limit the side of the outer box, squeezing and driving the side to gradually swing to 90 degrees, completing the box opening action. Compared with the prior art, this utility model automatically opens the sheet-shaped outer box, facilitates the loading of the inner box, completes the packaging process, and improves work efficiency.

The specific contents are as follows:

[0020] 1. A box opening assembly is provided inside and at the bottom of the workbench. When opening a box, the box is placed on the top of the workbench with one side contacting the vertical plate. The telescopic cylinder can then be activated to extend. Due to the presence of the torsion spring, the telescopic cylinder can drive the movable plate to move after extension, so that the fixed frame slides on the support rod, so that the positioning plate fits the other side of the box. The fixed frame can drive the L-shaped rod to move during the movement.

The air is pumped out, and the packaging box is fixed under the action of atmospheric pressure. After the packaging box is fixed, the movable plate continues to move to drive the L-shaped rod to slide on the mounting plate and stretch the telescopic spring. When the telescopic spring is stretched, the torsion spring will not produce excessive deformation. The movable plate moves to make the positioning plate abut against the other side of the packaging box. Then the telescopic cylinder can push the movable plate to rotate. The rotation of the movable plate can push the packaging box along the fold to complete the opening. The box opening assembly makes it possible to open boxes of different sizes, thereby improving the overall scope of application. The packaging box can be fixed while opening, thereby improving practicality.

[0021] 2. When opening the packaging box, the electric push rod is started to drive the movable block to move upward. While moving upward, the movable block slides on the guide rod to limit its position. After the movable block moves upward, it can drive the ejector pin to move. After the ejector pin moves, it can drive the connecting rod to rotate on the connecting frame. After the connecting rod rotates, it can push the ejector pin to slide inside the movable block. While moving upward, the ejector pin can extend into the interior of the packaging box, and then the packaging box can be opened with the help of the ejector pin, which improves practicality.

[0032] Working principle: Before using this kind of box opening device for packaging box forming, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, a box opening component 2 is provided inside and at the bottom of the workbench 1. When opening a packaging box, the packaging box is placed on the top of the workbench 1, with one side abutting against the vertical plate 102. Then the telescopic cylinder 205 can be started to extend. Due to the presence of the torsion spring 207, the telescopic cylinder 205 can drive the movable plate 202 to move after it extends, so that the fixed frame 206 slides on the support rod 2061, so that the positioning plate 203 fits with the other side of the packaging box. The fixed frame 206 can drive the L-shaped rod 209 to move during the movement. After the L-shaped rod 209 moves, the movable rod 216 can be driven to move through the mounting plate 217, so that the piston 215 moves inside the cylinder 214. After the piston 215 moves, the suction cup 212 is evacuated through the connecting pipe 213, so that the packaging box and the suction cup are in contact. The lever 212 is pressed against the bottom edge of the packaging box 217, and the suction cup 212 is evacuated to fix the packaging box under the action of atmospheric pressure. After the packaging box is fixed, the movable plate 202 continues to move to drive the L-shaped rod 209 to slide on the mounting plate 217 and stretch the telescopic spring 218. When the telescopic spring 218 is stretched, the torsion spring 207 does not produce excessive deformation. The movable plate 202 moves to make the positioning plate 203 abut against the other side of the packaging box. Then the telescopic cylinder 205 can push the movable plate 202 to rotate. The movable plate 202 rotates to push the packaging box along the fold to complete the opening of the box. The opening assembly 2 allows packaging boxes of different sizes to be opened, thereby improving the overall scope of application. The packaging box can be fixed while opening the box, thereby improving practicality.

[0033] When the packaging box is opened, the electric push rod 302 is started to drive the movable block 303 to move upward. While the movable block 303 moves upward, it slides on the guide rod 304 to limit its position. After the movable block 303 moves upward, it can drive the ejector pin 305 to move. After the ejector pin 305 moves, it can drive the connecting rod 306 to rotate on the connecting frame 307. After the connecting rod 306 rotates, it can push the ejector pin 305 to slide inside the movable block 303. While moving upward, the ejector pin 305 can extend into the interior of the packaging box, and then the ejector pin 305 can assist in the packaging box opening operation, thereby improving practicality.
