DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 5A PET sheet conveying device includes a frame 1, a first roller 2 is arranged on the frame 1, one end of the first roller 2 is connected to the output shaft 5 of the motor 6, the motor 6 drives the first roller 2 to rotate, so as to achieve the purpose of conveying the PET sheet 4, the motor 6 is arranged on the support seat 7, the support seat 7 is connected to the frame 1 through the fixing bolt 8, and a second roller 3 is arranged above the first roller 2, a PET sheet 4 is placed between the first roller 2 and the second roller 3, the PET sheet 4 passes through the first guide roller 9, the second guide roller 22, and the lead-out roller 23 in turn, and two groups of induction lifting rolling cleaning mechanisms are staggered between the first guide roller 9 and the second guide roller 22, one group is used to clean the dust on the upper surface of the PET sheet 4, and the other group is used to clean the dust on the lower surface of the PET sheet 4.

[0021] Reference Figure 3-Figure 5 The cleaning mechanism includes a rotating shaft 10, on which a sticky paper roll 11 is movably sleeved. After the sticky paper roll 11 has been used for a period of time, a layer of sticky paper on the surface can be torn off and the sticky paper roll 11 can be continued to be used until all the sticky paper rolls 11 are used up and a new sticky paper roll 11 can be replaced. One end of the rotating shaft 10 is connected to a mounting plate 12, and a fixing plate 15 is provided at the other end. The mounting plate 12 is provided on one side of an electric slider 13, and the electric slider 13 is slidably connected to an electric guide rail 14. The electric slider 13 can drive the rotating shaft 10 to slide on the electric guide rail 14, thereby adjusting the height of the sticky paper roll 11 so that it is always in contact with the surface of the PET sheet 4. The electric guide rail 14 is connected to the inner wall of the frame 1, and the fixing plate 15 is connected to the fixing block 16. The fixing block 16 is fixed to the rotating shaft 10 by a positioning bolt 17 At one end, when replacing the sticky paper roll 11, the positioning bolt 17 can be rotated to remove the fixing plate 15 and the fixing block 16, and then reinstall them after replacement. The cleaning mechanism also includes a positioning plate 18, and an infrared sensor 21 is arranged on the positioning plate 18, which is used to sense whether the sticky paper roll 11 is in contact with the surface of the PET sheet 4. When not in contact, the signal is transmitted to the electric guide rail 14 to control the electric slider 13 to slide until the sticky paper roll 11 is in contact with the surface of the PET sheet 4. The positioning plate 18 is installed on the frame 1 through a limiting bolt 19, and a slide groove 20 is arranged on one side of the frame 1. One end of the limiting bolt 19 is arranged in the slide groove 20, and the limiting bolt 19 slides in the slide groove 20 to adjust the height of the infrared sensor 21 to achieve the purpose of adapting to PET sheets 4 of different thicknesses.

[0022] During use, the PET sheet 4 passes through the first roller 2, the first guide roller 9, the second guide roller 22, and the lead-out roller 23 in sequence, the motor 6 is started, the first roller 2 rotates, and the PET sheet 4 is conveyed forward by friction. During the conveying process, the rotating shaft 10 also rotates under the action of friction. The two sets of sticky paper rolls 11 clean the dust on the upper and lower surfaces of the PET sheet 4 respectively. The infrared sensor 21 detects whether the sticky paper rolls 11 are in contact with the surface of the PET sheet 4. If not, the electric slider 13 will automatically adjust to a suitable position.
