Description

Technical Field

[0001] This invention relates to the field of photosensitive material plate production equipment, specifically to an aluminum plate sealing device for photosensitive material plates, a photosensitive material plate, and a method for sealing aluminum plates for photosensitive material plates. Background Technology

[0002] The production of photosensitive material plates uses aluminum plates and photosensitive emulsion. The photosensitive emulsion is sprayed onto the aluminum plate to form the photosensitive material plate. The aluminum plate is anodized, and this anodized aluminum plate undergoes sealing. This sealing process creates a porous alumina film (porosity approximately 5%–30%) on the surface of the anodized aluminum plate. While this porous structure has strong adsorption capacity, facilitating the subsequent adhesion of the photosensitive emulsion, it also has poor corrosion resistance. Therefore, sealing is necessary. Sealing is achieved through physical or chemical means to fill or reduce the micropores on the oxide film surface. For example, room temperature sealing involves using a solution containing inorganic salts such as nickel fluoride at room temperature (20℃–30℃). The principle is a dissolution-deposition reaction, where the resulting nickel hydroxide precipitate fills the pores in the film. The device used is an aluminum plate sealing device for photosensitive material plates.

[0003] A sealing device for aluminum plates used in photosensitive materials includes a sealing groove with an internal cavity. The sealing groove has an entry side on the left and an exit side on the right. External guide rollers are installed on the entry and exit sides, namely a left external guide roller on the left and an external guide roller on the right. Two internal guide rollers are installed in the cavity, namely a left internal guide roller on the left and a right internal guide roller on the right. The aluminum plate passes through the upper side of the left external guide roller, the lower sides of the two internal guide rollers, and the upper side of the right external guide roller to form a sealing path. In the prior art, there is no component in the sealing groove to repeatedly bend the aluminum plate to be sealed. The aluminum plate to be sealed does not undergo repeated bending in the sealing groove, which has the disadvantage of not achieving a satisfactory sealing effect. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a sealing device and method for aluminum plates used in photosensitive material boards that offers better sealing performance.

[0005] The technical solution of the aluminum plate sealing device for photosensitive material plates of the present invention is as follows: The aluminum plate sealing device for photosensitive material plates includes a sealing groove, the sealing groove having an internal cavity, the sealing groove having an entry side on the left and an exit side on the right, and an outer guide roller is installed on the entry side and the exit side respectively, namely a left outer guide roller on the left and a right outer guide roller on the right; an inner guide roller is installed in the cavity, and there are two inner guide rollers, namely a left inner guide roller on the left side of the cavity and a right inner guide roller on the right side of the cavity; The aluminum plate forms a sealing path by passing through the upper side of the left outer guide roller, the lower sides of the two inner guide rollers, and the upper side of the right outer guide roller; characterized in that: a rubber component is also installed in the groove cavity, the rubber component has a through gap from left to right, the gap has a left end on the left side and a right end on the right side, the left inner guide roller is installed on the upper side of the left end of the gap, the right inner guide roller is installed on the upper side of the right end of the gap, the cross-section of the gap is a structure of multiple complete waves, and the gap is a segment of the sealing path.

[0006] Furthermore, the rubber component is made of hollow rubber. In use, the groove cavity is filled with sealing liquid, and the rubber component floats on top of the sealing liquid, while the gap is below the sealing liquid. The rubber component has multiple sliders around it, and the inner side of the sealing groove has multiple vertical grooves, in which the sliders are installed.

[0007] Furthermore, the gap has a narrow section, the upper and lower parts of which are made of silicone rubber. In its natural state, the height of the gap is less than the thickness of the aluminum plate to be sealed.

[0008] In one embodiment, the narrow slit segment has at least two complete waveform structures.

[0009] Furthermore, the gap has a section that is made of sponge, with the top and bottom of the sponge section being made of sponge, and the sponge section is in front of the narrow gap section.

[0010] Furthermore, the rubber part is also equipped with a vibration device, the vibration device generates an amplitude of 2-3 mm, and the vibration frequency of the vibration device is 5-10 Hz.

[0011] The technical solution of the method for sealing holes in aluminum plates for photosensitive material plates of the present invention is as follows: In the method for sealing holes in aluminum plates for photosensitive material plates, the aluminum plate to be sealed is sealed by repeatedly bending it into a wavy shape.

[0012] When sealing the holes, the sealing fluid used is the upper layer sealing fluid.

[0013] During the sealing process, the top and bottom of the aluminum plate to be sealed are wiped with silicone rubber. This process is called silicone rubber wiping.

[0014] During the sealing process, the top and bottom of the aluminum plate to be sealed are wiped with a sponge. This sponge wiping process follows the silicone rubber wiping process.

[0015] During the sealing process, the aluminum plate to be sealed is also subjected to vertical vibration, with an amplitude of 2-3 mm and a frequency of 5-10 Hz.

[0016] The technical solution of the photosensitive material plate of the present invention is implemented as follows: the photosensitive material plate includes an aluminum plate and a photosensitive adhesive, wherein the aluminum plate is an oxidized aluminum plate with an oxide layer, and the oxide layer is further sealed. The photosensitive adhesive is sprayed onto the oxide layer of the aluminum plate to form the photosensitive material plate; the characteristic is that the aluminum plate is obtained by the above-mentioned aluminum plate sealing method for the photosensitive material plate.

[0017] A method for manufacturing a photosensitive material plate involves oxidizing an aluminum plate to form an oxide layer on its surface, sealing the oxide layer after oxidation, and then spraying photosensitive adhesive onto the oxide layer to form a photosensitive material plate. The method is characterized in that the sealing of the oxide layer is performed using the sealing method described in claim 6, 7, or 8.

Detailed Implementation

[0025] To gain a deeper understanding of the present invention, the invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] As shown in the figure, the aluminum plate sealing device for photosensitive material plates includes a sealing groove 1, which has an internal cavity 11. The sealing groove has an entry side 12 on the left and an exit side 13 on the right. External guide rollers 2 are installed on the entry and exit sides respectively, namely a left external guide roller 21 on the left and a right external guide roller 22 on the right. Two internal guide rollers 3 are installed inside the cavity: a left internal guide roller 31 on the left and a right internal guide roller 32 on the right. The aluminum plate passes through the left external guide roller... The upper side of the roller, the lower sides of the two inner guide rollers, and the upper side of the right outer guide roller form a sealing route 4; characterized in that: a rubber component 5 is also installed in the groove cavity, the rubber component has a through gap 51, the gap has a left end 52 on the left and a right end 53 on the right, the left inner guide roller 31 is installed on the upper side of the left end of the gap, the right inner guide roller 32 is installed on the upper side of the right end of the gap, the cross section of the gap is a structure of multiple complete waves, and the gap is a segment of the sealing route.

[0027] With the above-mentioned configuration of the present invention, when sealing holes in an aluminum plate, the aluminum plate is repeatedly bent in the sealing liquid, which can further reduce the porosity of the sealing holes and achieve the purpose of the present invention.

[0028] In one embodiment, the narrow slit segment has at least two complete waveform structures.

[0029] Furthermore, the rubber component is made of hollow rubber 50. In use, the groove cavity is filled with sealing liquid, and the rubber component floats on the surface of the sealing liquid, while the gap is below the sealing liquid. The rubber component is surrounded by multiple sliders 54, and the inner side of the sealing groove has multiple vertical grooves 14, in which the sliders are installed.

[0030] The above-mentioned configuration of the present invention allows the main sealing path within the tank cavity to change with the rise and fall of the sealing liquid. That is, this sealing path is always close to the top of the sealing liquid, and the sealing liquid used has fewer impurities, thus achieving a better sealing effect.

[0031] In one technical solution, the hollow core has an opening and a sealed cap on the opening (view omitted). This allows different weights to be placed inside the hollow core to adjust the overall mass of the rubber component, making it suitable for sealing liquids of different densities. It also allows adjustment of the position of the rubber component in the sealing liquid.

[0032] The rubber component is made of hollow rubber, which ensures that it has a certain degree of buoyancy. This prevents the rubber component from sinking to the bottom of the cavity due to its high density.

[0033] Furthermore, the gap has a narrow gap section 511, the upper and lower parts of which are made of silicone rubber 58. In its natural state, the height of the gap is less than the thickness of the aluminum plate to be sealed.

[0034] The above-described configuration of this invention also allows the aluminum plate to be wiped by silicone rubber during the sealing process, achieving a better sealing effect. With this configuration, there will always be sealing fluid in the gaps, acting on the surface of the aluminum plate.

[0035] In one embodiment, the aluminum plate is not wiped with silicone rubber and has a porosity of 2% after sealing; in another embodiment, the aluminum plate is wiped with silicone rubber and has a porosity of 1% after sealing.

[0036] Specifically, such as Figure 1 , 5 As shown, the surface of the silicone rubber has a toothed structure, which has tooth peaks 581 and tooth valleys 582. The height of the gap being less than the thickness of the aluminum plate to be sealed means that the distance between the upper and lower silicone rubber tooth peaks is less than the thickness of the aluminum plate to be sealed; the distance between the upper and lower silicone rubber tooth valleys is greater than the thickness of the aluminum plate to be sealed.

[0037] The present invention is configured such that when the aluminum plate to be sealed passes through the tooth peaks, the surface of the aluminum plate can be wiped; when the aluminum plate to be sealed passes through the tooth valleys, the sealing liquid can enter the surface of the aluminum plate and act on the surface of the aluminum plate to perform normal sealing.

[0038] The above-mentioned settings of the present invention can achieve a very high frequency of wiping and sealing of the surface of the sealing hole repeatedly, so as to achieve a better sealing effect.

[0039] Furthermore, the gap has a section that is a sponge gap section 512, the upper and lower parts of which are made of sponge 57, and the sponge gap section is in front of the narrow gap section.

[0040] The above-mentioned configuration of the present invention also allows the aluminum plate to be wiped by the sponge during the sealing process, which can achieve a better sealing effect.

[0041] In one embodiment, the aluminum plate, without being wiped by a sponge, has a porosity of 1% after sealing; in another embodiment, the aluminum plate, after being wiped by a sponge, has a porosity of 0.5% after sealing.

[0042] Furthermore, the rubber part is also equipped with a vibration device 6, the vibration device generates an amplitude of 2-3 mm, and the vibration frequency of the vibration device is 5-10 Hz.

[0043] The above-mentioned settings of the present invention can also make the aluminum plate vibrate during the sealing process, which can achieve a better sealing effect.

[0044] In one embodiment, the aluminum plate is not vibrated and has a porosity of 1% after sealing; in another embodiment, the aluminum plate is vibrated and has a porosity of 0.5% after sealing.

[0045] In one embodiment, the rubber component has an upper panel 55 on its upper surface and a lower panel 56 on its lower surface.

[0046] The above-mentioned design of the present invention can also prevent the entire rubber component from becoming too soft and limp.

[0047] The technical solution of the method for sealing holes in aluminum plates for photosensitive materials of the present invention is as follows: In the method for sealing holes in aluminum plates for photosensitive materials, the aluminum plate to be sealed is sealed in the liquid in the sealing tank and is subjected to repeated bending and wavy deformation.

[0048] During the sealing process, the sealing fluid used is the upper layer of sealing fluid in the sealing tank.

[0049] During the sealing process, the top and bottom of the aluminum plate to be sealed are also wiped with silicone rubber. This process is called silicone rubber wiping.

[0050] During the sealing process, the top and bottom of the aluminum plate to be sealed are wiped with a sponge. This sponge wiping process follows the silicone rubber wiping process.

[0051] During the sealing process, the aluminum plate to be sealed is also subjected to vertical vibration, with an amplitude of 2-3 mm and a frequency of 5-10 Hz.

[0052] The above technical solutions can achieve better sealing results.
