The cylinder barrel of the electric cylinder 172 is fixed in the mounting groove 171.

[0028] Embodiment 3: The food packaging bag composite film printing detection device provided by the preferable embodiment of the utility model differs from the above-mentioned embodiments only in that:

[0029] The positioning mechanism 194 is installed on the cross plate 180, and the positioning mechanism 194 is provided for quickly positioning and aligning the paper tube or plastic tube on both sides. The positioning mechanism 194 comprises a U-shaped plate 1941, a second guide rod 1942, a pull plate 1943, a locking piece 1944 and a spring 1945. The U-shaped plate 1941 is fixed to the outer wall of the two cross plates 180. The second guide rod 1942 slides through the U-shaped plate 1941 and the cross plate 180 at the same time. The center line of the second guide rod 1942 is aligned with the center line of the inflatable shaft 191. One end of the second guide rod 1942 is fixed to the outer wall of the pull plate 1943. The spring 1945 is fixed between the U-shaped plate 1941 and the pull plate 1943. The second guide rod 1942 passes through the spring 1945.

[0030] Working principle: in use, according to the model of the rolled composite film and the paper tube, the pull plate 1943 is moved, that is, the position of the second guide rod 1942 is adjusted. After adjustment, hold the pull plate 1943, rotate the locking piece 1944, and the end of the locking piece 1944 is pressed against the outer wall of the second guide rod 1942, so that the second guide rod 1942 is fixed on the U-shaped plate 1941. Then the rolled composite film and the empty paper tube are sleeved on different inflatable shafts 191, and the rolled composite film and the paper tube are pressed against the second guide rod 1942. Then the inflatable shaft 191 works to fix the rolled composite film and the paper tube. Then the composite film is pulled out of the rolled composite film, and then passes through the guide roller 192 and is fixed on the empty paper tube. The motor 161 drives the double-headed threaded rod 162 to work. The two partitions 164 move towards or away from each other under the joint action of the double-headed threaded rod 162 and the first guide rod 163, so as to adjust the distance between the two partitions 164, that is, to separate the print on the composite film. Then the image acquisition device 140, the industrial computer 150 and the double-output shaft motor 190 work to realize the winding and unwinding of the composite film under the action of the double-output shaft motor 190, the belt transmission member 193, the rolled composite film and the paper tube. The image acquisition device 140 takes a photo of the print. The industrial computer 150 identifies the image. When the image is unqualified, the industrial computer 150 transmits a signal to the control main terminal, and the control main terminal controls the electric cylinder 172 to work. The piston rod of the electric cylinder 172 extends to drive the marker pen 173 to mark on the composite film. Then the piston rod of the electric cylinder 172 returns to the initial position. Then the composite film is continuously detected. The food packaging bag composite film print detection device uses the positioning mechanism 194 to quickly position and align the rolled composite film and the empty paper tube, and is convenient for adjusting the distance between the two partitions 164, saving time and effort, improving the detection efficiency of the print, and bringing better use experience to the user.
