[0035] As mentioned in the background art, conventional laser marking equipment cannot be used to identify colored tubes. The original marking method, inkjet pad printing, requires flipping the tube to achieve markings greater than 240°. This method suffers from poor ink adhesion, easy detachment, and staining, cumbersome maintenance, high consumable costs, and low operating efficiency. Furthermore, inkjet pad printing marking uses ink with low adhesion, easily scraped off, and high consumable costs. Furthermore, it can only mark one-third of the tube circumference at a time. If markings greater than 240° are required, the formed tube must be flipped over. Since most products are irregularly shaped, i.e., non-straight tubes, the flipping process is time-consuming and labor-intensive, and the consumable costs are high.

[0036] In order to solve this technical problem, the utility model provides a color tube ultraviolet laser marking device, please refer to Figure 1-5 , specifically including:

The ultraviolet laser head is selected to realize laser marking and marking of multiple color tubes 9. Ordinary laser heads cannot realize color marking such as: red, yellow, green, purple, blue, etc.; the ultraviolet laser emission heads 5 of the two ultraviolet laser marking mechanisms are located in the same vertical direction; the lifting and lateral adjustment tooling includes a first mechanical slide 6 and a second mechanical slide 7, and the first mechanical slide 6 and the second mechanical slide 7 are arranged vertically.

[0039] Please refer to Figure 4 、 5The pipe stopper 4 has two sets of U-shaped openings 41, which are staggered and located on different sides of the pipe stopper 4.

Therefore, two workstations are designed to accommodate pipes of different shapes. The pipe stopper 4 is provided with a through-port 42 that communicates with the through-port 3. The pipe stopper 4 is removably mounted on the cantilever plate 2 using bolts (the bolts and screw holes are not shown in the figure).

The pipe limiting tool 4 is provided with a hole groove 44 that is connected to the two U-shaped opening grooves 41. The detection ends of the two in-place sensors 43 are installed at both ends of the hole groove 44; the in-place sensor 43 is preferably an infrared sensor or other sensor with in-place signal transmission. The internal structure and principle of the in-place sensor 43 are not within the scope of protection of this case and will not be further elaborated or limited here.

The ultraviolet light can simultaneously perform laser marking and marking on the upper and lower surfaces of the color tube, achieving a marking range of more than 240° at one time without turning over (the 240° here means that the arc of the marking on the upper and lower surfaces of the color tube is more than 240° in total, which can be understood as the upper ultraviolet laser emission head marks a 120° mark, and the lower ultraviolet laser emission head marks a 120° mark). Marking 120° lines), the marking efficiency of pipe fittings is improved from 30 seconds / piece for a single double line to 10 seconds / piece, and it can achieve 240° marking of various colored pipe fittings in one action without flipping, and the marking is clear.

In another embodiment, please refer to Figure 6 The other end of the pipe pressing member 46 is rotatably connected to the output end 452. The side of the pipe pressing member 46 near the output end 452 is hingedly connected to a transmission rod 462, which is further hingedly connected to the support column 453. The telescopic movement of the telescopic cylinder 451 drives the pressure block 461 to flip and rotate. In another embodiment, the pipe pressing member 46 can also be fixedly installed at the output end of the driving member 45, and the driving member 45 drives the pipe pressing member 46 to move up and down.
