When it is required to perform the dipping process on the substrate 001, the first passing roller 200 rotates around its own axis to support and transfer the substrate 001 into the dipping liquid in the tank 100, then the dipping roller 300 presses and transfers the substrate 001 in the dipping liquid to complete the dipping process on the substrate 001, and then the dipping roller 300 outputs the substrate 001 from the tank 100 to the second passing roller 400, and the second passing roller 400 supports and transfers the substrate 001 to a subsequent processing apparatus. When the dipping roller 300 needs to be cleaned, the pressing roller 500 is driven to descend so as to squeeze the substrate 001 between the first passing roller 200 and the pressing roller 500, and then the dipping roller 300 is driven to move upwards by the first driving member 700, and the substrate 001 does not move upwards synchronously along with the dipping roller 300 due to the pressing of the pressing roller 500 and the first passing roller 200, so that the dipping roller 300 is separated from the substrate 001, and the dipping roller 300 can be cleaned directly without worrying about touching and destroying the substrate 001 during cleaning, so that the cleaning dipping roller 300 does not need to cut the substrate 001, and does not touch and destroy the substrate 001 under the condition of not cutting the substrate 001. Specifically, after the cleaning of the dipping roller 300 is completed, the first driving member 700 drives the dipping roller 300 to move downward, so that the dipping roller 300 contacts and presses the substrate 001 again, and then drives the pressing roller 500 to ascend to release the pressing of the substrate 001, and then the dipping process of the substrate 001 can be continued.
Specifically, if the base material 001 in the tank 100 is not pressed by the pressing roller 500 and the first passing roller 200, the base material 001 in the tank 100 may be pulled up by gravity by the base material 001 that has not entered the tank 100 while the dipping roller 300 is ascending, thereby following the dipping roller 300 to move upward synchronously, so that the dipping roller 300 cannot be separated from the base material 001. The body of the base material 001 is wound around a cylinder and then transported through the first passing roller 200 or the like; because the cylinder is placed lower, when the dipping roller 300 moves upward, the substrate 001 below the dipping roller 300 is pulled around the first passing roller 200 by the substrate 001 on the cylinder and between the cylinder and the trough 100, so that the substrate 001 below the dipping roller 300 also moves upward along with the dipping roller 300, and the dipping roller 300 cannot be separated from the substrate 001.
In this embodiment, the substrate 001 is a subband made of carbon fiber; the second pass roller 400 is used to transport the substrate 001 to the oven; the press roll 500 is positioned right above the first passing roll 200, and the substrate 001 is positioned between the press roll 500 and the first passing roll 200; when the base material 001 is immersed, the base material 001 is worn in advance, so that the base material 001 bypasses above the first passing roller 200 and then stretches into the immersion liquid in the trough 100, then bypasses from the bottom of the immersion roller 300, and then the base material 001 bypasses from the trough 100 and from above the second passing roller 400; when the base material 001 is subjected to the dipping treatment, the dipping roller 300 is located in the trough 100, specifically, in general, the dipping roller 300 is located in the trough 100; when it is desired to clean the dip roll 300 or other special conditions are encountered, the dip roll 300 is raised and/or the trough 100 is lowered, the dip roll 300 may be moved beyond the trough 100 above the trough 100.
Specifically, the height of the first roller 200 is higher than the height of the trough 100, so that the process of conveying the substrate 001 into the trough 100 by the first roller 200 is more convenient.
