Description

Technical Field

[0001] This utility model belongs to the field of packaging and printing technology, and in particular relates to an electrolytic treatment device for a thermal CTP plate. Background Technology

[0002] There are currently four types of CTP plates on the market: thermal, silver halide, photopolymer, and pre-treatment-free. CTP plate-making technology is divided into photosensitive CTP plate-making technology and thermal CTP plate-making technology. Photosensitive CTP plates include silver halide diffusion plates, high-sensitivity resin plates, and silver halide / PS composite plates; thermal CTP plates include thermal cross-linking plates, thermal ablation plates, and thermal transfer plates. The electrolytic treatment device for thermal CTP plates (computer-to-plate) is a key piece of equipment in the plate-making production line, mainly used for electrolytic roughening of the plate material to enhance the surface adhesion, hydrophilicity, and printing performance of the plate base (usually aluminum). The main components of CTP plate electrolysis are: Electrolytic tank: a corrosion-resistant container holding the electrolyte (usually hydrochloric acid, nitric acid, or a mixed acid solution); Electrode system: Anode: aluminum plate base (the CTP plate to be treated); Cathode: inert material (such as titanium, stainless steel, or graphite). The system includes a power supply system, an electrolyte circulation system, a temperature control unit, and a waste gas treatment device. However, the following drawbacks still exist in actual electrolysis treatment:

[0003] The main functions of electrolytic aluminum plate base are: to form a uniform microporous structure on the surface of the aluminum plate base through electrolytic corrosion, thereby improving the adhesion of the photosensitive layer (thermal coating), removing the oxide layer and impurities on the surface of the aluminum plate, ensuring the quality of subsequent processing (such as anodizing and coating), and allowing the roughened surface to better retain moisture, reducing the problem of dirt on the printing process. However, during the electrolysis of the aluminum plate base, it is necessary to clamp the aluminum plate base. The clamped position of the aluminum plate base may not be able to fully contact the electrolyte, resulting in local non-electrolysis, which will affect the processing effect. If the clamping part (such as the clamp or conductive point) is mechanically blocked, the electrolyte in that area may not be able to flow freely, forming a "shielded area" that hinders the oxidation reaction or metal deposition.

[0004] Secondly, the size of the aluminum plate base is not uniform. The CTP plates used in different devices are of different sizes, which leads to the inconsistency of the aluminum plate base size. Therefore, different amounts of electrolyte and different sizes of electrolytic cells are required to be used together. However, the current size of electrolytic cells is generally constant and the size of the electrolytic cell cannot be changed.

[0005] Finally, after long-term use, some impurities may be generated in the electrolyte. If these impurities are not filtered or adjusted to the original concentration, the electrolysis effect will still be reduced, and improvements and optimizations are needed. Utility Model Content

[0006] The purpose of this utility model is to provide an electrolytic treatment device for a thermal CTP plate. By setting up a clamping assembly, an electrolytic cell, an isolation frame, a partition, a filter, and a delivery pump, it solves the problems that when the clamping fixture holds the aluminum plate for electrolysis, the clamping position may not be able to fully contact the electrolyte, resulting in partial failure to electrolyze; it is not applicable to electrolytic treatment of aluminum plates of various sizes; and the electrolyte needs to be filtered after long-term use.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is an electrolytic treatment device for a thermal CTP plate, including an electrolytic cell, a filter, a delivery pump, a mounting plate and a clamping assembly. The filter is provided on one side of the electrolytic cell and the delivery pump is provided on one end of the electrolytic cell.

[0009] The inner wall of the electrolytic cell is fixed with equidistantly distributed isolation frames, each isolation frame having a cavity and a partition inserted into the cavity;

[0010] Support plates are fixed at both ends of the top of the electrolytic cell, and two sliding rods are fixed between the two support plates.

[0011] The mounting plate is placed between two sliding rods, and a cylinder is fixed at the upper end of the mounting plate. The piston rod at the telescopic end of the cylinder passes through the mounting plate downward and is rotatably connected to a crossbeam. Multiple clamping components are slidably arranged below the crossbeam.

[0012] The clamping assembly includes a clamping plate one and a clamping plate two, and each of the clamping plate one and the clamping plate two has a pair of conductive needles that are spiked and arranged in a rectangular array fixed on their opposite surfaces.

[0013] Furthermore, a rubber pad is fixed on the outer edge of the partition, and a slot is provided on the inner wall of the isolation frame outside the cavity, into which the outer edge of the partition and the rubber pad are inserted.

[0014] Furthermore, each of the two sides of the isolation frame has a drain pipe fixed through the bottom of the electrolytic cell and extends outwards. One end of the drain pipe extending out of the electrolytic cell is fixed through the filter, and a valve is installed on the part of the drain pipe extending out of the electrolytic cell.

[0015] Furthermore, a pumping pipe is fixed to the pumping end of the pump, and the end of the pumping pipe away from the pump is fixedly connected to the end of the filter. An outlet pipe is fixed to the pumping end of the pump, and the end of the outlet pipe away from the pump extends into the electrolytic cell.

[0016] Furthermore, both ends of the mounting plate are fixed with sleeves, and the two sleeves are slidably fitted onto the two sliding rods respectively.

[0017] Furthermore, a sliding groove is provided at the lower part of the crossbeam, a connecting rod is fixed at the upper end of the clamping plate, a slider is fixed at the upper end of the connecting rod, and the slider is slidably disposed in the sliding groove. A power connection post is also fixed at the upper end of the clamping plate next to the connecting rod.

[0018] Furthermore, a stud is fixed to the surface of the clamping plate above the conductive needle, and the end of the stud away from the clamping plate extends through the clamping plate and is screwed with a wing nut.

[0019] This utility model has the following beneficial effects:

[0020] This invention solves the problem of partial electrolysis failure when clamping aluminum plates during electrolysis by setting up clamping components. The clamping position may not be able to fully contact the electrolyte, leading to localized electrolysis failure. When clamping the aluminum plate, the appropriate number of clamping components is selected based on the size of the aluminum plate. The aluminum plate is placed between clamping plate one and clamping plate two. Then, the wing nut on the stud is rotated, causing clamping plate two to move closer to clamping plate one until clamping plate one and clamping plate two clamp the aluminum plate tightly. Because conductive pins are provided on the opposing surfaces of clamping plate one and clamping plate two, the tips of the conductive pins contact the aluminum plate. Although this increases the contact points, it greatly reduces the contact area, hardly affecting the flow of electrolyte. The clamping position will not fail to contact the electrolyte, preventing localized electrolysis failure. This effectively ensures that electrolysis can be carried out fully and effectively while clamping. Clamping plate one, clamping plate two, stud, and conductive pins are all made of metallic conductive materials, while the connecting rod is made of non-metallic insulating material.

[0021] This invention solves the problem of being unable to electrolyze aluminum plates of various sizes by setting up an electrolytic cell, an isolation frame, and partitions. Depending on the size of the aluminum plate to be electrolyzed, partitions are inserted into an appropriate isolation frame; for example, if only one area needs to be electrolyzed, then... Figure 1 As shown, if a larger area is needed, such as three areas, insert a partition into the third partition, then move the mounting plate and rotate the crossbeam to make it parallel to the long side of the electrolytic cell, and then clamp the aluminum plate base for electrolysis.

[0022] This invention solves the problem of electrolyte filtration after long-term use by setting up a filter and a delivery pump. After the electrolyte has been used for a period of time, the valve can be opened to allow the electrolyte to enter the filter, and then be pumped by the delivery pump to the electrolytic cell. After repeating this process for a period of time, the filtration process can be completed. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0034] Please see Figure 1-7 As shown, this utility model is an electrolytic treatment device for a thermal CTP plate, including an electrolytic cell 1, a filter 2, a delivery pump 3, a mounting plate 4 and a clamping assembly 5. The filter 2 is provided on one side of the electrolytic cell 1, and the delivery pump 3 is provided on one end of the electrolytic cell 1.

[0035] Electrolytic cell 1 stores a certain amount of electrolyte for electrolytic treatment. Filter 2 is used to filter the electrolyte after a period of use. Then, in conjunction with transfer pump 3, the filtered electrolyte is pumped back to electrolytic cell 1.

[0036] An equidistantly distributed isolation frame 105 is fixed on the inner wall of the electrolytic cell 1. A cavity 1051 is provided inside the isolation frame 105, and a partition 106 is inserted into the cavity 1051.

[0037] By inserting a partition 106 into the corresponding isolation frame 105, the area in the electrolytic cell 1 can be divided into different sizes, thus adapting to aluminum plate bases of different sizes for electrolytic treatment.

[0038] Two support plates 101 are fixed at both ends of the top of the electrolytic cell 1, and two sliding rods 102 are fixed between the two support plates 101; two sleeves 401 are fixed at both ends of the mounting plate 4, and the two sleeves 401 are slidably sleeved on the two sliding rods 102 respectively.

[0039] Mounting plate 4 is placed between two sliding rods 102, and cylinder 402 is fixed at the upper end of mounting plate 4. The piston rod at the telescopic end of cylinder 402 passes through mounting plate 4 and is rotatably connected to crossbeam 403. Multiple clamping components 5 are slidably arranged below crossbeam 403.

[0040] The slide bar 102 is installed using the support plate 101, and the mounting plate 4 is slidably sleeved on the slide bar 102 through the sleeve 401, so that the mounting plate 4 can be linearly moved along the slide bar 102 to adjust the corresponding position. After the aluminum plate base and the cathode are clamped by the clamping assembly 5, the cylinder 402 can work to drive the crossbeam 403 to descend, so that the clamping assembly 5 and the aluminum plate base are immersed in the electrolyte for electrolytic treatment.

[0041] The clamping assembly 5 includes a first clamping plate 501 and a second clamping plate 502. On the opposite surfaces of the first clamping plate 501 and the second clamping plate 502, there are conductive needles 503 that are spike-shaped and arranged in a rectangular array.

[0042] Clamping plate 1 501 and clamping plate 2 502 clamp the aluminum plate base and the cathode. According to the corresponding aluminum plate base size, select an appropriate number of clamping components 5 for clamping. Clamping plate 2 502 is brought close to clamping plate 1 501 and locked until the conductive pin 503 between clamping plate 1 501 and clamping plate 2 502 contacts the aluminum plate base and clamps it.

[0043] A rubber pad 1061 is fixed on the outer edge of the partition 106. A slot 1052 is provided on the inner wall of the isolation frame 105 outside the cavity 1051. The outer edge of the partition 106 and the rubber pad 1061 are inserted into the slot 1052. The partition 106 is inserted into the cavity 1051 inside the isolation frame 105, and the edge of the partition 106 and the rubber pad 1061 are inserted into the slot 1052. This not only restricts the position of the partition 106, but also ensures sufficient sealing and prevents the electrolyte from flowing on both sides of the partition 106.

[0044] Each isolation frame 105 has a drain pipe 103 fixed through the bottom of the electrolytic cell 1 on both sides and extends out. One end of the drain pipe 103 extending out of the electrolytic cell 1 is fixed through the filter 2, and a valve 104 is installed on the part of the drain pipe 103 extending out of the electrolytic cell 1.

[0045] When it is necessary to filter the electrolyte, open valve 104 to allow the drain pipe 103 to be open, and the electrolyte in the electrolytic cell 1 will enter the filter 2 through the drain pipe 103.

[0046] The pump 3 has a pump pipe 301 fixed at its pumping end. The end of the pump pipe 301 away from the pump 3 is connected to the end of the filter 2. The pump 3 has an outlet pipe 302 fixed at its outlet end. The end of the outlet pipe 302 away from the pump 3 extends into the electrolytic cell 1.

[0047] The electrolyte filtered by filter 2 is pumped out of filter 2 by pump 3 through pump pipe 301 and then output to electrolytic cell 1 through outlet pipe 302. After a period of time, the filtration is completed.

[0048] The lower part of the crossbeam 403 is provided with a sliding groove 4031, the upper end of the clamping plate 501 is fixed with a connecting rod 5011, the upper end of the connecting rod 5011 is fixed with a slider 5012, and the slider 5012 is slidably disposed in the sliding groove 4031. The upper end of the clamping plate 501 next to the connecting rod 5011 is also fixed with a power connection post 5013.

[0049] On clamping plate 501, a connecting rod 5011 is used to connect slider 5012 to slide groove 4031, so that slider 5012 can slide in slide groove 4031, thereby changing the position of clamping component 5 and adapting it to aluminum plate bases of various sizes for clamping use.

[0050] A stud 504 is fixed on the surface of the clamping plate 501 above the conductive needle 503. The end of the stud 504 away from the clamping plate 501 extends through the clamping plate 502 and is screwed with a wing nut 5041.

[0051] Rotate the wing nut 5041 to bring the second clamp 502 closer to the first clamp 501 until the first clamp 501 and the second clamp 502 clamp the aluminum plate base tightly.

[0052] The specific working principle of this utility model is as follows: First, based on the size of the aluminum plate base, select the required electrolysis area within the electrolytic cell 1. If only one area is needed for electrolysis, then... Figure 1As shown, the partition 106 is inserted into the first adjacent isolation frame 105, and the partition 106 is inserted into the cavity 1051 inside the isolation frame 105. The edge of the partition 106 is fitted with the rubber pad 1061 and inserted into the slot 1052. Then, the mounting plate 4 is moved above the electrolysis area. Then, an appropriate number of clamping components 5 are selected to clamp the aluminum plate base and the cathode. The aluminum plate base is placed between the first clamping plate 501 and the second clamping plate 502. Then, the wing nut 5041 on the stud 504 is rotated so that the second clamping plate 502 moves closer to the first clamping plate 501 until the first clamping plate 501 and the second clamping plate 502 clamp the aluminum plate base. Because conductive pins 503 are provided on the opposite surfaces of the first clamping plate 501 and the second clamping plate 502, the tips of the conductive pins 503 contact the aluminum plate base and clamp it. Then, the cylinder 402 drives the crossbeam 403 to descend, so that the clamping components 5 and the aluminum plate base are immersed in the electrolyte for electrolysis.

[0053] After the electrolyte has been used for a period of time, valve 104 can be opened, and the electrolyte in the electrolytic cell 1 will enter the filter 2 through the drain pipe 103. Then, through the operation of the transfer pump 3, the electrolyte filtered in the filter 2 will be extracted by the water pumping pipe 301 and output to the electrolytic cell 1 through the water outlet pipe 302. After a period of time, the filtration will be completed.

[0054] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
