The working principle of the pushing type automatic adhesive tape sticking machine for the aluminum tube of the LED fluorescent lamp is as follows:
in operation, the pushing and moving plate 24 is at the rightmost end, the left limit block 261 is at the uppermost end, the right limit block 271 is at the lowermost end, and the right end of the adhesive tape is clamped between the left limit block 261 and the right limit block 271, at this time, the adhesive tape is in a tensioned state and is arranged right above the aluminum pipe arrangement groove 210 from left to right, the aluminum pipe (not shown) is installed in the aluminum pipe arrangement groove 210 with the adhesive end face facing upward, the pushing and moving plate 24 moves from right to left, so that the pressing wheel 242 presses the adhesive tape to be adhered to the aluminum pipe (not shown), in this process, the adhesive tape roll mounting disc 29 rotates clockwise step by step to keep the adhesive tape in a tensioned state and avoid the adhesive tape from deforming, so that the pushing and moving plate 24 reaches the leftmost end, then the suction nozzle 244 moves downward to suck the adhesive tape, then the left and right ends of the adhesive tape on the aluminum pipe are cut off manually, the left limiting block 261 descends, the right limiting block 271 ascends, the adhesive tape waste on the left limiting block is manually removed, meanwhile, the pushing and moving plate 24 moves from left to right to return, the right end of the adhesive tape is driven to the right end of the upper supporting plate 15, in the process, the adhesive tape roll mounting disc 29 rotates clockwise step by step to keep the adhesive tape in a tensioned state and avoid the deformation of the adhesive tape, then the left limiting block 261 ascends to abut against the adhesive tape, the right limiting block 271 descends and the left limiting block 261 act together to clamp the right end of the adhesive tape, then the suction force of the suction nozzle 244 disappears and ascends, and;
meanwhile, as the adhesive tape is continuously consumed, the adhesive tape roll mounting disc 29 gradually rises to ensure that the adhesive tape is positioned right above the aluminum pipe support plate 21 but is not released from the aluminum pipe (not shown) in advance, so that accidental adhesion is avoided.
The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description herein, since various changes and modifications can be made in the details of the embodiment and the application range according to the spirit of the present invention.
