TECHNICAL FIELD
[0001] The utility model relates to the technical field of the production equipment of photosensitive material board, and concretely relates to a photosensitive material substrate pickling device. BACKGROUND
[0002] The substrate used in the production of photosensitive material board is an aluminum substrate. During the production of photosensitive material board, the substrate needs to be pickled first. The pickling is performed by using, for example, dilute sulfuric acid to form an oxide film on the substrate, so that the photosensitive chemical liquid on the substrate is bonded more firmly, thereby forming a photosensitive material board. Therefore, the quality of the oxide film directly affects the quality of the product.
[0003] The photosensitive material substrate pickling device comprises a pickling tank, which has a left substrate inlet end and a right substrate outlet end. A variable-diameter roller is installed on the top and inside of the pickling tank. A conveying roller driven by a conveying motor is also installed on the pickling tank. The substrate enters from the inlet end, passes through the variable-diameter roller, is conveyed by the conveying roller, and is output from the outlet end to form a running route of the substrate, thereby completing the pickling of the substrate.
[0004] In the prior art, the photosensitive material substrate pickling device cannot wipe the substrate during pickling, has poor pickling effect, and is not conducive to improving product quality. SUMMARY
[0005] The utility model aims at the above-mentioned shortcomings and provides a photosensitive material substrate pickling device which can wipe the surface of the substrate during pickling, has good pickling effect, and is conducive to improving product quality.
[0006] The technical solution of the utility model is as follows: a photosensitive material substrate pickling device comprises a pickling tank, which has a left substrate inlet end and a right substrate outlet end. A variable-diameter roller is installed on the top and inside of the pickling tank. A conveying roller driven by a conveying motor is also installed on the pickling tank. The substrate enters from the inlet end, passes through the variable-diameter roller, is conveyed by the conveying roller, and is output from the outlet end to form a running route of the substrate, thereby completing the pickling of the substrate.
[0007] Further, the wiping roller has a plurality of openings around it.
[0008] Furthermore, the wiping material layer is a cloth layer or a rubber material layer.
[0009] Furthermore, multiple support rollers are installed inside the pickling tank, and these support rollers are located below the arc-shaped path.
[0010] The beneficial effects of this utility model are: such a photosensitive material substrate pickling device has the advantages of being able to wipe the surface of the substrate during the pickling process, having a good pickling effect, and being conducive to improving product quality.

[0016] In the description of the preferred embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate link; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0017] To better understand this utility model, the following description, in conjunction with the accompanying drawings, will provide further details.
[0018] like Figure 1 , 2As shown in Figures 3 and 4, a photosensitive material substrate pickling device includes a pickling tank 1, which has an inlet end 11 on the left side for the substrate and an outlet end 12 on the right side for the substrate. A variable diameter roller 2 is installed on and inside the pickling tank. A conveying roller 3 driven by a conveying motor 31 is also installed on the pickling tank. The substrate enters from the inlet end, undergoes diameter change by the variable diameter roller, is conveyed by the conveying roller, and is output from the outlet end, forming a substrate running path 4. A frame 5 is provided on the side of the pickling tank. The device is characterized by: a wiping roller 6 installed on the frame, and a wiping motor 61 installed on the frame. The wiping motor is connected to the wiping roller. A wiping material layer 62 is provided around the wiping roller. The wiping roller extends into the pickling tank. The running path also passes through an arc-shaped surface below the wiping roller, forming an arc-shaped path 41.
[0019] The above-mentioned features of this invention allow the substrate to be wiped during the oxidation process, thereby achieving the purpose of this invention.
[0020] The pickling tank is also equipped with a conveying roller 3 driven by a conveying motor, which ensures that the substrate moves from left to right in the pickling tank.
[0021] Furthermore, the wiping roller rotates in the direction from right to left, i.e. Figure 1 The middle part moves clockwise, which is opposite to the direction of the running path.
[0022] This design ensures the uniformity of the oxide layer on the substrate.
[0023] Furthermore, the wiping roller has multiple notches 63 around it.
[0024] This design also has the advantage of better wiping effect on the oxide layer, as the notch extends through the front and back of the wiping roller.
[0025] Furthermore, the width of the notch is 3-4 millimeters.
[0026] This design also has the advantage of better wiping effect on the oxide layer.
[0027] Furthermore, the wiping material layer is a cloth layer or a rubber material layer.
[0028] Furthermore, multiple support rollers 7 are installed inside the pickling tank, and these support rollers are located below the arc-shaped path.
[0029] This design also has the advantage of better wiping effect on the oxide layer.
[0030] In a further improved technical solution, the outer periphery of the support roller is further covered with a rubber layer, which is a second rubber layer 71.
[0031] This design also has the advantage of better wiping effect on the oxide layer.
[0032] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
