Technical Field

[0001] This invention relates to the field of photosensitive material plate production equipment technology, specifically to a photosensitive material plate spraying device and a photosensitive material plate production method. Background Technology

[0002] A photosensitive material plate spraying device includes a frame on which a raw material roller, a variable diameter roller, a product roller, and a spraying device are mounted. An aluminum plate is released from the raw material roller and reaches the product roller to form a production path. The production path is further deflected by the variable diameter roller, creating a zigzag structure. The spraying device includes a spray head, with the spray point facing the production path. The spray head sprays photosensitive material onto the surface of the aluminum plate to form a photosensitive material layer, thus transforming the aluminum plate into a photosensitive material plate. In existing technology, the production path facing the spray head is planar, which limits the number of printing cycles of the produced photosensitive material plates; for example, under normal circumstances, the number of printing cycles can reach 35,000. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned shortcomings by providing a photosensitive material plate spraying apparatus and a photosensitive material plate production method that can increase the number of printing passes.

[0004] The technical solution of the photosensitive material plate spraying device of the present invention is implemented as follows: A photosensitive material spraying device includes a device frame, on which a raw material roller, a variable diameter roller, a product roller and a spraying device are installed. An aluminum plate is released from the raw material roller and runs forward to the product roller to form a production route. The production route is also changed in direction by the variable diameter roller, so that the production route forms a zigzag structure. The spraying device includes a photosensitive adhesive container and a spraying head connected to the photosensitive adhesive container. The part of the spraying head facing the production route is the spraying point. The spraying head sprays the photosensitive adhesive onto the surface of the aluminum plate to form a photosensitive material layer, thus turning the aluminum plate into a photosensitive material plate. The characteristic is that the production route where the spraying point is located has a convex arc structure, and the convex arc structure is formed by the variable diameter roller acting on the production route.

[0005] Furthermore, the spray head includes a rear spray head and a front spray head, and the spray point includes a rear spray point and a front spray point. The spray head facing the rear spray point is the rear spray head, and the spray head facing the front spray point is the front spray head. There is a drying section on the production line before the spray point. The section before the rear spray point is the rear drying section, and the section before the front spray point is the front drying section. A drying device is also installed on the device frame. The drying device can dry the photosensitive material plate in the drying section. The drying device is a blowing device. The blowing device has a blowing outlet connected to an air supply pipe. The blowing outlet faces the drying section and uses the blown drying gas to dry the photosensitive emulsion. The blowing outlet facing the rear drying section is the rear blowing outlet, and the blowing outlet facing the front drying section is the front blowing outlet.

[0006] Furthermore, the blowing device includes a gas storage tank, and the blowing outlet is connected to the gas storage tank by a delivery pipe. The gas storage tank is a gas storage tank for nitrogen, carbon dioxide, or a mixture of nitrogen and carbon dioxide.

[0007] Furthermore, a first air conditioner is installed on the device frame, which can make the temperature of the air coming out of the rear air outlet and the aluminum plate of the rear drying section reach T1, the value range of T1 being 20-25℃; a second air conditioner is installed on the device frame, which can make the temperature of the air coming out of the front drying section and the aluminum plate of the front drying section reach T2, the value range of T2 being 18-23℃.

[0008] Furthermore, the photosensitive emulsion container includes a first container and a second container, with a rear spray head connected to the first container and a front spray head connected to the second container; it also includes a third air conditioner and a fourth air conditioner, wherein the third air conditioner is capable of ensuring that the temperature of the photosensitive emulsion sprayed from the rear spray head reaches T3, and T3 is 7-10°C lower than T1; the fourth air conditioner is capable of ensuring that the temperature of the photosensitive emulsion sprayed from the front spray head reaches T4, and T4 is 7-10°C lower than T2.

[0009] Furthermore, the raw material roller has a raw material roller insulation box on its outer periphery, the raw material roller insulation box has a box door and a discharge gap, the production route passes through the discharge gap, and the device also includes a fifth air conditioner installed on the raw material roller insulation box, the fifth air conditioner can make the temperature inside the raw material roller insulation box reach T5, the temperature of T5 being 5-7°C lower than T1.

[0010] Furthermore, the product roller has a product roller insulation box on its outer periphery, the product roller insulation box has a box door and a receiving gap, the production route passes through the receiving gap, and the device also includes a sixth air conditioner installed on the product roller insulation box, the sixth air conditioner can make the temperature inside the product roller insulation box reach T6, the T6 being equal to the temperature T2.

[0011] The technical solution of the photosensitive material plate production method of the present invention is as follows: The photosensitive material plate production method uses photosensitive adhesive and aluminum plate as raw materials. The photosensitive adhesive is uniformly sprayed onto the surface of the aluminum plate. The photosensitive adhesive solidifies to form a photosensitive material layer to obtain the photosensitive material plate. When spraying the aluminum plate, the aluminum plate is in a convex arc structure, and the photosensitive adhesive is sprayed onto the surface of the convex arc structure. This process is the spraying process.

[0012] Furthermore, the spraying process consists of at least two parts: a first spraying process and a second spraying process.

[0013] Furthermore, after each spraying process is completed, the surface of the sprayed photosensitive emulsion is dried by blowing air to make the solvent of the photosensitive material layer evaporate faster. The airflow blown onto the photosensitive emulsion is nitrogen gas, carbon dioxide gas, or a mixture of nitrogen and carbon dioxide gas. This process is the drying process.

[0014] Furthermore, the drying process is carried out while the photosensitive material plate is in a flat state.

[0015] Furthermore, after the first spraying process, the temperature of the aluminum plate reaches T1, with a value range of 20-25℃; after the second spraying process, the temperature of the aluminum plate reaches T2, with a value range of 18-23℃.

[0016] Furthermore, during the first spraying, the temperature of the photosensitive emulsion is T3, which is 7-10°C lower than T1; during the second spraying, the temperature of the photosensitive emulsion is T4, which is 7-10°C lower than T2.

[0017] Furthermore, when spraying the aluminum plate, the temperature of the aluminum plate is T5, and T5 is 5-7°C lower than T1.

[0018] Furthermore, after forming the photosensitive material plate, the photosensitive material plate is also subjected to a fixation treatment at a temperature of T6, which is equal to the temperature of T2.

[0019] The beneficial effects of this invention are that the photosensitive material plate spraying apparatus and the photosensitive material plate production method obtained by this invention have the advantage of increasing the number of printing cycles. Attached Figure Description

[0022] In the description of the preferred embodiments of the present invention, 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 the present invention according to the specific circumstances.

[0023] It should be noted that the air conditioner can make the air coming out of the air outlet and the aluminum plate of the drying section reach a certain temperature. The air conditioner can be used to change the temperature of the gas stored in the gas tank. Alternatively, the air conditioner can have a cold air circulation pipe, which is wrapped around the gas pipeline to change the temperature of the blown gas. The same structure can also be used to change the temperature of the photosensitive emulsion.

[0024] To better understand this invention, the following description, in conjunction with the accompanying drawings, will provide further details.

[0025] like Figure 1As shown, a photosensitive material plate spraying device includes a frame 1, on which a raw material roller 11, a variable diameter roller 12, a product roller 13, and a spraying device 2 are mounted. An aluminum plate is released from the raw material roller and moves forward to the product roller to form a production route 15. The production route is also changed in direction by the variable diameter roller, forming a zigzag structure. The spraying device includes a photosensitive adhesive container 21 and a spraying head 22 connected to the photosensitive adhesive container. The part of the spraying head facing the production route is the spraying point 151. The spraying head sprays the photosensitive adhesive onto the surface of the aluminum plate to form a photosensitive material layer, thus turning the aluminum plate into a photosensitive material plate. The characteristic is that the production route where the spraying point is located has a convex arc structure, which is formed by the variable diameter roller acting on the production route.

[0026] The present invention employs the above-mentioned technical method, in which the aluminum plate is in a convex arc-shaped structure during the spraying of photosensitive adhesive, so that the surface of the aluminum plate has more photosensitive adhesive, which can improve the printing effect, for example, by 5-8% under normal circumstances, thus achieving the purpose of the present invention.

[0027] Furthermore, the spray head includes a rear spray head 221 and a front spray head 222, and the spray points include a rear spray point 1511 and a front spray point 1512. The spray head facing the rear spray point is the rear spray head 221, and the spray head facing the front spray point is the front spray head 222. There is also a drying section 152 on the production line in front of the spray points. The rear drying section 1521 is in front of the rear spray point, and the front drying section 1522 is in front of the front spray point. A drying device 3 is also installed on the device frame. The drying device can dry the photosensitive material plate in the drying section. The drying device is a blowing device. The blowing device has a blowing outlet 31 connected to the air supply pipe. The blowing outlet faces the drying section and uses the blown drying gas to dry the photosensitive adhesive. The blowing outlet facing the rear drying section is the rear blowing outlet 311, and the blowing outlet facing the front drying section is the front blowing outlet 312.

[0028] The present invention employs the above-mentioned technique, namely, the photosensitive emulsion is sprayed twice, and a drying is performed after each spraying, which can significantly increase the number of prints on the photosensitive material plate. Based on the above-mentioned embodiments (i.e., based on sequential spraying), the number of prints is generally increased by 4-5%.

[0029] In one technical solution, the drying section is a straight section on the production route.

[0030] The present invention adopts the above technical solution, which also has the advantages of a smoother product surface and fewer spots observed under a microscope, thereby improving product quality and increasing the rate of high-quality products.

[0031] Furthermore, the blowing device includes a gas storage tank 32, and the blowing outlet is connected to the gas storage tank by a delivery pipe. The gas storage tank is a gas storage tank for nitrogen, carbon dioxide, or a mixture of nitrogen and carbon dioxide.

[0032] The present invention adopts the above-mentioned technology and also has the advantage of a longer shelf life of the photosensitive adhesive on the photosensitive material plate. Under normal circumstances, the shelf life can be extended by 20%.

[0033] Furthermore, a first air conditioner 41 is installed on the device frame, which can make the temperature of the air coming out of the rear air outlet and the aluminum plate of the rear drying section reach T1, the value range of T1 being 20-25℃; a second air conditioner 42 is installed on the device frame, which can make the temperature of the air coming out of the front drying section and the aluminum plate of the front drying section reach T2, the value range of T2 being 18-23℃.

[0034] The present invention, by employing the above-mentioned techniques, also has the advantage of obtaining better product quality. For example, the printed pattern has good clarity and long preservation time. In general, burrs may easily appear around the pattern in the later stages of printing. Using the above-mentioned technical solution of the present invention, the phenomenon of burrs around the pattern is significantly reduced.

[0035] Furthermore, the photosensitive emulsion container includes a first container 211 and a second container 212, with a rear spray head 221 connected to the first container and a front spray head 222 connected to the second container; it also includes a third air conditioner 43 and a fourth air conditioner 44, wherein the third air conditioner is capable of making the temperature of the photosensitive emulsion sprayed from the rear spray head reach T3, wherein T3 is 7-10°C lower than T1; and the fourth air conditioner is capable of making the temperature of the photosensitive emulsion sprayed from the front spray head reach T4, wherein T4 is 7-10°C lower than T2.

[0036] The above-mentioned settings of the present invention, namely, controlling the temperature of the photosensitive emulsion during the two spraying processes, result in a more durable product.

[0037] Furthermore, the raw material roller has a raw material roller insulation box 5 on its outer periphery. The raw material roller insulation box has a door and a discharge gap. The production route passes through the discharge gap. The device also includes a fifth air conditioner 45 installed on the raw material roller insulation box. The fifth air conditioner can make the temperature inside the raw material roller insulation box reach T5. The temperature T5 is 5-7°C lower than T1.

[0038] The above-mentioned configuration of the present invention also has the advantages of saving the amount of photosensitive emulsion, achieving the same quality, and reducing costs.

[0039] Furthermore, the product roller has a product roller insulation box 6 on its outer periphery. The original product roller insulation box has a box door and a receiving gap. The production route passes through the receiving gap. The device also includes a sixth air conditioner 46 installed on the product roller insulation box. The sixth air conditioner can make the temperature inside the product roller insulation box reach T6, where T6 is equal to the temperature of T2.

[0040] The above-mentioned features of the present invention also have the advantage of extending the shelf life of the photosensitive material plate.

[0041] The technical solution of the photosensitive material plate production method of the present invention is as follows: The photosensitive material plate production method uses photosensitive adhesive and aluminum plate as raw materials. The photosensitive adhesive is uniformly sprayed onto the surface of the aluminum plate. The photosensitive adhesive solidifies to form a photosensitive material layer to obtain the photosensitive material plate. When spraying the aluminum plate, the aluminum plate is in a convex arc structure, and the photosensitive adhesive is sprayed onto the surface of the convex arc structure. This process is the spraying process.

[0042] Furthermore, the spraying process consists of at least two parts: a first spraying process and a second spraying process.

[0043] Furthermore, after each spraying process is completed, the surface of the sprayed photosensitive emulsion is dried by blowing air to make the solvent of the photosensitive material layer evaporate faster. The airflow blown onto the photosensitive emulsion is nitrogen gas, carbon dioxide gas, or a mixture of nitrogen and carbon dioxide gas. This process is the drying process.

[0044] Furthermore, the drying process is carried out while the photosensitive material plate is in a flat state.

[0045] Furthermore, after the first spraying process, the temperature of the aluminum plate reaches T1, with a value range of 20-25℃; after the second spraying process, the temperature of the aluminum plate reaches T2, with a value range of 18-23℃.

[0046] Furthermore, during the first spraying, the temperature of the photosensitive emulsion is T3, which is 7-10°C lower than T1; during the second spraying, the temperature of the photosensitive emulsion is T4, which is 7-10°C lower than T2.

[0047] Furthermore, when spraying the aluminum plate, the temperature of the aluminum plate is T5, and T5 is 5-7°C lower than T1.

[0048] Furthermore, after forming the photosensitive material plate, the photosensitive material plate is also subjected to a fixation treatment at a temperature of T6, which is equal to the temperature of T2.
