Technical Field

[0001] The present invention relates to the technical field of photosensitive material plate production equipment, and also to a photosensitive material plate production method, in particular to a photosensitive material plate production device and a photosensitive material plate production method. Background Art

[0002] The photosensitive material plate is a consumable material for printing. After a certain number of prints, it will be scrapped due to pattern problems. The photosensitive material plate includes a substrate below and a photosensitive material coating on the substrate. The substrate is an aluminum alloy thin plate. The photosensitive material coating is formed by condensing the photosensitive material coated on the substrate. The photosensitive material is also called photosensitive material solution.

[0003] The production of photosensitive material plates is completed on a photosensitive material plate production device, which includes a device frame, on which are provided a substrate roller and a product roller. When in use, the substrate is wound around the substrate roller, and the photosensitive material plate to be produced is wound around the product roller. The substrate forms a production route from the substrate roller to the product roller. There is also a photosensitive material liquid nozzle on the device frame, and the nozzle faces the production route. The nozzle can spray the photosensitive material liquid. The photosensitive material liquid is sprayed on the substrate and condensed to produce the photosensitive material plate.

[0004] In the prior art, the photosensitive material plate production devices are basically processed in a free state. For example, the photosensitive material liquid sprayed by the spray head is directed to the substrate in a free state. The products produced in this way have fewer print runs, and after a certain number of prints, the pattern is prone to cracks, and new photosensitive material plates must be replaced, which is not conducive to extending the life of the photosensitive material plates. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned shortcomings and provide a photosensitive material plate production device and a photosensitive material plate production method that can extend the service life and reduce the occurrence of breakage after printing a certain number of patterns.

[0006] The technical solution adopted by the photosensitive material plate production device of the present invention is as follows: the photosensitive material plate production device includes a device frame, on which there are a substrate roller and a product roller. When in use, the substrate is wound on the substrate roller, and the photosensitive material plate to be produced is wound on the product roller. The substrate forms a production route from the substrate roller to the product roller. There is also a nozzle for photosensitive material liquid on the device frame, and the nozzle faces the production route. The part where the nozzle faces the production route is the spraying point. The nozzle can spray the photosensitive material liquid to produce the photosensitive material plate; its characteristic is that: there are also two pairs of tension wheels installed on the device frame, and the two pairs of tension wheels are respectively a front tension wheel installed in front of the spraying point and a rear tension wheel installed behind the spraying point. The part between each pair of tension wheels is the part where the production route passes, and each pair of tension wheels clamps the production route. The tension wheels are connected to a motor, and the peripheral speed of the front tension wheel is greater than the peripheral speed of the rear tension wheel.

[0007] Furthermore, a top wheel is installed on the device frame, the production route is located above the top wheel, and the top wheel is installed below the spraying point, so that the substrate is in a raised state at the spraying point.

[0008] In one technical solution, the central angle of the raised state is 90-120 degrees, and the radius of the top wheel is 10-20 centimeters.

[0009] In one technical solution, the cross section of the front tensioner along the shaft core is an "H"-shaped structure with expansion edges on both sides, and the two expansion edges are components acting on the sides of the base.

[0010] Furthermore, the above-mentioned spray head and spray point are respectively the rear spray point and the rear spray head, and the rear spray point and the rear spray head form a rear spray unit. There is also a front spray unit in front of the rear spray unit on the device frame, and the front spray unit includes a front spray head and a front spray head point.

[0011] Furthermore, a rear insulation chamber is installed on the device frame around the rear spraying unit, and the rear insulation chamber makes the internal temperature around the rear spraying unit reach 30-35°C; a front insulation chamber is also installed on the device frame around the front spraying unit, and the front insulation chamber makes the internal temperature around the front spraying unit reach 25-30°C, and the temperature of the rear insulation chamber is 5-7°C higher than the temperature in the front insulation chamber.

[0012] Furthermore, a product insulation chamber is installed on the device frame, and the product insulation chamber can keep the temperature inside at 20-22°C.

[0013] The technical solution adopted by the photosensitive material plate production method of the present invention is as follows: the photosensitive material plate production method, the materials used to produce the photosensitive material plate include a substrate, the substrate is an aluminum alloy plate, and a layer of photosensitive material liquid is sprayed on the substrate during production. The feature is that when spraying the liquid, the substrate is in a stretched state and sprayed thereon.

[0014] Furthermore, the spraying of the substrate includes two spraying steps, namely a first spraying step and a second spraying step, wherein the second spraying step is performed when the substrate is in a natural state.

[0015] Furthermore, the spraying of the substrate includes two sprayings, namely the first spraying and the second spraying. The first spraying is carried out at an ambient temperature of 30-35°C, and the second spraying is carried out at an ambient temperature of 25-30°C. The ambient temperature of the first spraying is 5-7°C higher than the ambient temperature of the second spraying.

[0016] Furthermore, after the second spraying of the photosensitive material plate is completed, the temperature of 20-22° C. is maintained for 24-48 hours.

[0017] The beneficial effects of the present invention are as follows: such a photosensitive material plate production device and a photosensitive material plate production method have the advantages of extending the service life and reducing the occurrence of breakage when a certain number of patterns are printed.

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, the photosensitive material plate production device includes a device frame 1, on which there are a substrate roller 11 and a product roller 12. When in use, the substrate is wound on the substrate roller, and the photosensitive material plate to be produced is wound on the product roller. The substrate forms a production route 13 from the substrate roller to the product roller. There is also a nozzle 3 for photosensitive material liquid on the device frame, and the nozzle faces the production route. The part of the nozzle facing the production route is the spraying point 31. The nozzle can spray the photosensitive material liquid to produce the photosensitive material plate; its characteristic is that: there are also two pairs of tension wheels 4 installed on the device frame, the two pairs of tension wheels are respectively a front tension wheel 41 installed in front of the spraying point and a rear tension wheel 42 installed behind the spraying point, between each pair of tension wheels is the part where the production route passes, and each pair of tension wheels clamps the production route, the tension wheels are connected to a motor 43, and the peripheral speed of the front tension wheel is greater than the peripheral speed of the rear tension wheel.

[0026] Design principle: Due to the above arrangement, when producing photosensitive material plates, the substrate is coated with photosensitive material solution in a stretched state, which has the effect of making the coated photosensitive material solution denser, so that the photosensitive material plates can be printed more times. That is, under the same scrap conditions, the number of prints can generally be increased by 6-8%, thereby obtaining better economic benefits.

[0027] The nozzle can be used as long as it can spray out photosensitive materials. For example, the nozzle is connected to a photosensitive material storage tank, and a pressure pump is provided on the photosensitive material storage tank so that the photosensitive material is sprayed out from the nozzle at a certain pressure. Those skilled in the art should know this.

[0028] For example, under the same conditions, the product obtained by the prior art is the first product, and the product obtained by the present invention is the second product. The number of prints of the first product can reach 5,000, and the number of prints of the second product can reach 5,400.

[0029] In one technical solution, the front tension wheel and the rear tension roller are connected to a motor, and the circumference of the front tension wheel is greater than the circumference of the rear tension roller. In short, as long as the substrate can be in a stretched state at the spraying position, it will be fine.

[0030] Furthermore, a top wheel 5 is installed on the device frame, and the production route is located above the top wheel. The top wheel is installed below the spraying point, so that the substrate is in a raised state at the spraying point.

[0031] The present invention is arranged in this way so that the substrate can be stretched more during spraying.

[0032] In a technical solution, the central angle α of the raised state is 90-120 degrees, and the radius r of the top wheel is 10-20 centimeters.

[0033] The present invention is arranged in this way to ensure the use effect of the formed convex state.

[0034] After testing, the printing rate of this product can be increased to 8-11% compared with the first product, which means the quality is improved again.

[0035] In a technical solution, Figure 2 As shown, the cross section of the front tensioner along the shaft core is an "H"-shaped structure with expansion edges 44 on both sides, and the two expansion edges are components acting on the sides of the base.

[0036] The present invention is configured in this way, which can reduce the direct effect of the front tensioner on the surface of the photosensitive material on the substrate. At this time, the surface coating of the photosensitive material plate is still relatively immature, and the front tensioner directly acts on the surface of the photosensitive material on the substrate, which is easy to cause damage. The extended edges on both sides act on the side of the substrate, which is the clamping part on the printing machine. Generally speaking, it is not the part where the pattern is formed, and it will not cause adverse effects on the product.

[0037] Furthermore, the spray head and the spray point are the rear spray point 311 and the rear spray head 32 respectively, and the rear spray point and the rear spray head form a rear spray unit. There is also a front spray unit in front of the rear spray unit on the device frame, and the front spray unit includes a front spray head 33 and a front spray head point 312.

[0038] According to the design principle, the present invention is configured in this way to achieve secondary spraying of photosensitive materials on the product, so that the printing quality is better and the printing times are improved; for example, after testing, the printing times of the obtained product can be increased to 12-15% compared with the first product, that is, the quality is improved again.

[0039] Furthermore, a rear insulation chamber 61 is installed on the device frame around the rear spraying unit, and the rear insulation chamber makes the temperature inside the rear spraying unit reach 30-35°C; a front insulation chamber 62 is also installed on the device frame around the front spraying unit, and the front insulation chamber makes the temperature inside the front spraying unit reach 25-30°C, and the temperature of the rear insulation chamber is 5-7°C higher than the temperature in the front insulation chamber.

[0040] According to the design principle, the present invention is configured in this way to realize spraying of the product under two different temperature conditions, so that the printing quality is better and the printing times are improved; for example, after testing, the printing times of the obtained product can be increased to 12-15% compared with the first product, that is, the quality is improved again.

[0041] Of course, in order to achieve a certain temperature in the front insulation chamber and the rear insulation chamber, a temperature regulating component 64 is respectively provided in the front insulation chamber and the rear insulation chamber. The temperature regulating component here includes a heating component or a cooling component, which should be known to those skilled in the art.

[0042] Furthermore, the device frame is also provided with a product insulation chamber 63, which can maintain the temperature inside at 20-22° C. When in use, the produced photosensitive material plate can be placed in the product insulation chamber for insulation treatment, generally for 24-48 hours.

[0043] The present invention is configured in this way, and also has the effect of extending the shelf life. For example, the shelf life is 36 months without insulation. After being treated in the insulation chamber of this product, the shelf life can be extended by 4-8 months to achieve the same aging state (attenuation of the photosensitive material layer).

[0044] Of course, in order to make the product insulation chamber reach a certain temperature, a temperature regulating component 64 is provided in the product insulation chamber. The temperature regulating component here includes a heating component or a cooling component, which should be known to those skilled in the art.

[0045] The technical solution adopted by the photosensitive material plate production method of the present invention is as follows: the photosensitive material plate production method, the materials used to produce the photosensitive material plate include a substrate, the substrate is an aluminum alloy plate, and a layer of photosensitive material liquid is sprayed on the substrate during production. The feature is that when spraying the liquid, the substrate is in a stretched state and sprayed thereon.

[0046] Furthermore, the spraying of the substrate includes two spraying steps, namely a first spraying step and a second spraying step, wherein the second spraying step is performed when the substrate is in a natural state.

[0047] Furthermore, the spraying of the substrate includes two sprayings, namely the first spraying and the second spraying. The first spraying is carried out at an ambient temperature of 30-35°C, and the second spraying is carried out at an ambient temperature of 25-30°C. The ambient temperature of the first spraying is 5-7°C higher than the ambient temperature of the second spraying.

[0048] Furthermore, after the second spraying of the photosensitive material plate is completed, the temperature of 20-22° C. is maintained for 24-48 hours.

[0049] It should be noted that the positive effects and functions of the photosensitive material plate production device of the above-mentioned embodiment can help explain the photosensitive material plate production method, and the above-mentioned photosensitive material plate production method can also help understand the photosensitive material plate production device; technical personnel in this field can understand each other based on the above-mentioned photosensitive material plate production device and photosensitive material plate production method.
