Description

Technical Field

[0001] The utility model relates to the technical field of plastic packaging bag production, in particular to a spraying device for plastic packaging bag production. Background Art

[0002] Plastic packaging bags are made of plastic as raw material and are widely used in daily life and industrial production. During the production process of plastic packaging bags, a spraying device is required to spray them. Spraying can enhance the wear resistance, corrosion resistance and UV resistance of plastic packaging bags, thereby extending the service life of the packaging bags. It can also form a protective film on the plastic surface. This film can not only prevent the packaging bags from being scratched or worn during use, but also resist the erosion of certain chemicals.

[0003] Most of the spraying devices currently used only have the function of clamping the packaging bags, but cannot make the packaging bags move back and forth. Workers are required to constantly move the parts that fix the packaging bags or hold the spray nozzles for spraying. Repetitive physical labor can easily lead to worker fatigue. This spraying method cannot achieve a uniform spraying effect, which will cause the thickness of the coating on the surface of the packaging bags to be uneven. In addition, the spraying device cannot turn the packaging bags over. After spraying one side of the packaging bag, the worker needs to remove the packaging bag and replace it. This method adds extra operation steps and time, thereby reducing overall production efficiency. Utility Model Content

The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to conventional methods in the field, and this technical solution will not be further elaborated.

[0025] Working principle: When spraying the packaging bag, turn on the stepper motor 61, and the stepper motor 61 can drive the driving shaft 62 to rotate. When the driving shaft 62 rotates, it can drive the turntable 63 to rotate, and then the turntable 63 rotates to move the first fixed column 64. Next, the movement of the first fixed column 64 can move the transmission rod 65. When the transmission rod 65 moves, it can drive the second fixed column 66 to move. Then, when the second fixed column 66 moves, it can drive the movable seat 7 to move back and forth. Next, the reciprocating movement of the movable seat 7 can drive the mounting seat 9 to move back and forth. When the mounting seat 9 moves back and forth, the parts above the mounting seat 9 can move back and forth, and then The packaging bag is moved back and forth. When the other side of the packaging bag needs to be sprayed, the rotating frame 111 is pressed down. When the rotating frame 111 rotates downward, the rotating rods 112 on both sides can rise, and then the rising rotating rods 112 on both sides can drive the clamping group 12 to rise. Next, the clamping group 12 can rotate during the rising process. When the clamping group 12 rotates, it can drive the fixed rods 115 on both sides to move, and then the movement of the fixed rods 115 on both sides can cause the linkage plates 114 on both sides to rotate. Next, when the linkage plates 114 on both sides are rotated to the appropriate position, the clamping group 12 can be turned over, and when the clamping group 12 is turned over, the packaging bag can be turned over.
