Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, in particular to an automatic laser bag opening machine. Background Art

[0002] Laser bag opening machine is a device that uses laser technology to open bags. It uses a high-energy laser beam to cut the bag material and form a neat opening at the bag mouth.

[0003] Referring to the Chinese patent with patent announcement number CN221621170U, an automatic laser bag opening machine is disclosed, including a workbench, a moving structure and a cleaning structure; the bag is placed on the placement plate, the telescopic part drives the clamping plate to descend, and the bag is clamped on the placement plate, the driving part drives the moving block to move, and drives the clamped bag to move toward the bottom of the laser head. At this time, the laser head performs a cutting operation on the bag through the square opening, the telescopic part drives the clamping plate to rise, and removes the bag from the placement plate. During cleaning, the lifting part drives the short cleaning plate brush to rise. At this time, the short cleaning plate is higher than the placement plate. At the same time, the motor drives the horizontal screw to rotate, driving the block to move horizontally along the groove, and drives the long cleaning plate brush to move. The long cleaning plate brush cleans the fine particles on the workbench, and the short cleaning plate brush cleans the fine particles on the placement plate.

[0004] However, during actual use of the laser bag opening machine, continuous movement of the bag body or the laser cutting machine can easily cause the particles produced by the laser cutting to come into contact with the position just cut, causing the two parts just cut to stick together, which will affect the actual bag opening effect.

On the other hand, by blowing air downward toward the position where the bag has just been opened, the edges of the two parts separated by the laser cutting are bent downward and separated, thereby increasing the opening area, thereby further effectively preventing the high-temperature particles from adhering.

[0017] 2. In the present invention, the outer walls of the bottom ends of the cutting sleeve, the air blowing head and the dust collecting head are all arranged flush with the top outer wall of the upper plate, so that there is a gap between the bottom ends of the cutting sleeve, the air blowing head and the dust collecting head and the surface of the bag body, so that the dust collecting head can absorb the particles before cutting, so as to facilitate the cutting operation.

[0018] 3. In the present invention, when the smoothing block and the vacuum head move close to the pressing block, the lower pressing pieces at both ends are used to pull and smooth the edges of the to-be-cut position outward, and cooperate with the smoothing block moving toward the side to improve the flatness of the position to be cut. When the cutting sleeve approaches for cutting operation, and the blowing head approaches after cutting is completed, the friction between the lower pressing piece and the surface of the bag body is used to pull the opening after cutting outward to increase, thereby effectively preventing the generated high-temperature particles from sticking again and affecting the bag opening operation effect.
