The workbench 1 is U-shaped, and the PET sheet 21 can be placed inside. The oil pump 24 is located on the upper side of the PET sheet 21. The oil in the oil storage tank 25 can be extracted through the first pipe 27, and then sprayed onto the PET sheet 21 through the second pipe 28 to achieve the oiling of the PET sheet 21. While oiling, the trackless cylinder 23 can drive the oil pump 24 to move, so that the entire upper side of the PET sheet 21 can be oiled, and the support rod 29 can support the first pipe 27, so that the first pipe 27 is not easy to collapse to the upper side of the PET sheet 21.

[0024] See also Figure 2-3 The clamping and flipping mechanism includes a second hollow groove 31 opened on one side of the workbench 1, a first hollow block 32 is connected to one side of the second hollow groove 31, a threaded rod 33 is connected to the inside of the first hollow block 32, and the threaded rod 33 is located on one side of the PET sheet 21, a ratchet 34 is connected to one side of the first hollow block 32, a first fixed rod 35 and a second fixed rod 37 are connected to one side of the workbench 1, a pawl 36 is connected to the outer side of the first fixed rod 35, and the pawl 36 and the ratchet 34 are meshed with each other, a leaf spring 38 is provided on the upper side of the pawl 36, and the leaf spring 38 is connected to the second fixed rod 37, a rotating block 39 is connected to the inside of the workbench 1, the PET sheet 21 can be placed between the threaded rod 33 and the rotating block 39, and the threaded rod 33 rotates when rotating The first hollow block 32 and the ratchet 34 will be driven to rotate, but the ratchet 34 will be limited by the pawl 36, so the first hollow block 32 cannot rotate. At this time, the threaded rod 33 threadedly connected to the first hollow block 32 can be moved by rotation, and the PET sheet 21 can be clamped after moving. Moreover, due to the threaded connection between the threaded rod 33 and the first hollow block 32, the clamping can be made more stable. When the PET sheet 21 needs to be turned over after coating one side, the threaded rod 33 can be directly rotated in the opposite direction. The threaded rod 33 will directly drive the first hollow block 32, the ratchet 34 and the PET sheet 21 to rotate and turn over, and will not be limited by the pawl 36, thereby realizing the turning over and oiling of the PET sheet 21, and there is no need to remove the PET sheet 21, turn it over and clamp it, which is more convenient.

A fixed block 43 is connected to the upper side of the slide rod 42, and a spring 44 is connected to the lower side of the fixed block 43, and the spring 44 is connected to the second hollow block 41. Since the reverse rotation of the threaded rod 33 can only drive the PET sheet 21 to rotate but cannot remove the PET sheet 21, the fixed block 43 can be pressed downward first, and the fixed block 43 will drive the slide rod 42 to move downward and press the pawl 36, so that the pawl 36 cannot rotate. At this time, the ratchet 34 and the first hollow block 32 cannot rotate either. Therefore, the threaded rod 33 can move by rotation, thereby disengaging from the PET sheet 21, which is convenient for removing the PET sheet 21, and the spring 44 can support the fixed block 43 and the slide rod 42, so that the slide rod 42 can be stabilized inside the second hollow block 41.

[0032] The working principle and use process of the utility model are as follows: first, the PET sheet 21 is placed between the threaded rod 33 and the rotating block 39, and then the threaded rod 33 is rotated, the threaded rod 33 will move inside the first hollow block 32, and the first hollow block 32 will be limited by the pawl 36 through the ratchet 34 and cannot rotate, so the threaded rod 33 can smoothly move and clamp the PET sheet 21, and because the threaded rod 33 is threadedly connected to the first hollow block 32, the clamping of the PET sheet 21 can be made more stable, and then the oil pump 24 is started to extract the oil inside the oil storage tank 25 through the first pipeline 27, and then sprayed onto the surface of the PET sheet 21 through the atomizing nozzle 53, and at the same time, the trackless cylinder 23 will drive the oil pump 24 to move, so as to realize the oiling work of the PET sheet 21;

[0033] After coating one side of the PET sheet 21, the threaded rod 33 can be rotated in the opposite direction, and the threaded rod 33 will drive the first hollow block 32 and the ratchet 34 to rotate.
