Description

A distance adjustment device for ceramic roller coating Technical Field

[0001] This utility model relates to the field of printing accessories manufacturing, specifically to the plasma spraying ceramic anilox roller industry, and particularly to a distance adjustment device for ceramic roller spraying. Background Technology

[0002] Ceramic anilox rollers are precision rollers with a ceramic coating. Their core feature is the formation of a uniform, micron-sized mesh structure (typically honeycomb or oblique grooves) on the ceramic surface through laser engraving. They are primarily used in the printing, coating, composite material molding, and functional surface treatment industries. In the printing industry, as a core component of flexographic and gravure printing, they store ink through the mesh and precisely transfer it to the substrate (such as plastic film or paper), controlling ink layer thickness and printing uniformity.

[0003] The manufacturing process of ceramic anilox rollers generally includes the following steps in sequence: ① substrate pretreatment ② plasma spraying of ceramic layer ③ surface grinding ④ laser engraving of cells ⑤ post-treatment. In the plasma spraying of the ceramic layer, ceramic powder is melted and sprayed onto the roller surface using plasma spraying. Currently, to achieve a higher deposition rate, a closer spraying distance is used because a closer spraying distance results in a higher deposition rate and better melting state. However, for some smaller diameter ceramic rollers, the surface temperature is high after spraying, and the engraved cell wall is brittle and prone to detachment, easily creating lines during the printing process and affecting print quality. More specifically, for ceramic rollers with a diameter less than 120mm, using a more traditional spraying distance leads to a high surface temperature after spraying, making the ceramic roller prone to deformation, and the ceramic cell wall is brittle and lacks toughness, making it easy to detach.

[0004] Therefore, there is a need for a ceramic roller spraying technology that can reduce the surface temperature after spraying, reduce the deformation of the roller body after spraying, and improve the toughness of the engraved mesh wall when plasma spraying ceramic layers onto small-diameter ceramic rollers. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a ceramic roller spraying technology solution that can reduce the surface temperature after spraying, reduce the deformation of the roller body after spraying, and improve the toughness of the engraved mesh wall when plasma spraying ceramic layers onto small-diameter ceramic rollers.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A distance adjustment device for ceramic roller spraying includes a spraying distance adjustment mechanism, a temperature sensor, and a main control module. The spraying distance adjustment mechanism is connected to the spray gun and can adjust the distance between the spray gun and the workpiece to be coated. The temperature sensor can measure the temperature of the surface of the workpiece to be coated. Specifically, the temperature sensor is equipped with a temperature sensor and is positioned facing the surface of the workpiece to be coated. The temperature sensor and the spraying distance adjustment mechanism are respectively connected to the main control module.

[0008] Specifically, the spraying distance adjustment mechanism includes a mounting beam mounted on a frame, the mounting beam being arranged parallel to the workpiece to be coated; a transverse moving component is slidably mounted on the mounting beam along its length, the transverse moving component being equipped with a lifting mechanism, and the spray gun being connected to the lifting mechanism.

[0009] Furthermore, the lifting mechanism includes a limiting guide rail, a lifting motor, and a transmission belt; the limiting guide rail is arranged in a vertical direction, and the transmission belt is driven by the lifting motor to move in a vertical direction;

[0010] The lifting mechanism is provided with a mounting base, which is slidably mounted on the limiting guide rail and is connected to the transmission belt. A spray gun facing the workpiece and a temperature sensor are mounted on the mounting base.

[0011] When the lifting motor drives the transmission belt to move, it can cause the entire mounting base to move vertically, thereby adjusting the distance between the spray gun and the workpiece (i.e., the ceramic roller). The above solution is one feasible technical solution; other technical solutions that can effectively adjust the distance between the spray gun and the workpiece can also be used as alternatives.

[0012] The temperature sensor is used to measure the surface temperature of the workpiece being coated, specifically the surface temperature after the ceramic roller has undergone plasma spraying of the ceramic layer. Since both the spraying distance adjustment mechanism and the temperature sensor are connected to the central control module, when the central control module detects from the signal collected by the temperature sensor that the surface temperature after the ceramic roller has undergone plasma spraying of the ceramic layer is too high (based on experience, temperatures exceeding 150 degrees Celsius pose a significant risk of the coating becoming too brittle and lacking toughness, or the ceramic roller deforming), the central control module can control the spraying distance adjustment mechanism to increase the distance between the spray gun and the workpiece being coated. This reduces the surface temperature after the ceramic roller has undergone plasma spraying of the ceramic layer, preventing deformation of the ceramic roller and a decrease in the toughness of the coating.

[0013] By adopting the above technical solution, the main control module can detect excessively high surface temperature of the ceramic roller through the temperature sensor and control the spraying distance adjustment mechanism to adjust the distance between the spray gun and the workpiece to be coated, so that the surface temperature of the ceramic roller is reduced to a range that will not cause deformation of the ceramic roller and reduction of the toughness of the mesh wall.

[0014] As an improvement, a distance sensor is also included, which is mounted on the mounting base and faces the workpiece to be coated. The distance sensor is arranged side by side with the spray gun (that is, the distance from the spray gun to the workpiece to be coated is equal to the distance from the distance sensor to the workpiece to be coated), and the distance sensor is signal-connected to the main control module.

[0015] As another solution, the distance from the distance sensor to the workpiece to be coated can be different from the distance from the spray gun to the workpiece to be coated, but the difference between the distance sensor and the distance from the spray gun to the workpiece to be coated should be constant. The main control module then calculates the distance from the spray gun to the workpiece to be coated based on the distance from the distance sensor to the workpiece to be coated and the difference between the distance sensor and the distance from the spray gun to the workpiece to be coated.

[0016] By adopting the above technical solution, the central control module can sense and record the distance data between the spray gun and the workpiece being coated through the distance sensor, and can further calculate the most suitable distance between the spray gun and the workpiece being coated to maintain the surface temperature within a safe range during plasma spraying for a certain type of workpiece based on the distance data between the spray gun and the workpiece being coated and the surface temperature data of the ceramic roller.

[0017] As an improvement, an air-blowing cooling module is also included, which has an air outlet facing the workpiece to be coated, and an air pump connected to the air outlet.

[0018] By adopting the above technical solution, when the distance between the spray gun and the workpiece is too large, but the surface temperature of the workpiece is still too high, the air-blowing cooling module can be activated to blow air onto the surface of the workpiece to reduce the temperature. Alternatively, air can be blown onto the surface of the workpiece to reduce the temperature while keeping the surface temperature within a safe range, in order to reduce the distance between the spray gun and the workpiece.

[0019] As an improvement, the air-blowing cooling module is also equipped with a refrigeration element, and the gas cooled by the refrigeration element is blown out through the air outlet by the air pump.

[0020] By adopting the above technical solution, the temperature of the airflow blown out of the air outlet is reduced by using refrigeration elements, thereby further improving the cooling effect of the air-blowing cooling module.

[0021] As an improvement, the air-blowing cooling module is also equipped with a liquid nitrogen storage chamber, which can release liquid nitrogen and blow it out through the air outlet.

[0022] By adopting the above technical solution, when it is necessary to improve the cooling effect of the air blowing cooling module, the liquid nitrogen storage tank can be controlled to release extremely cold nitrogen gas to blow air onto the surface of the workpiece to reduce the temperature.

[0023] As an improvement, the air-blowing cooling module is also equipped with an inlet air temperature sensor, which is signal-connected to the cooling element.

[0024] By adopting the above technical solution, when the factory temperature is too high and the ambient air is insufficient to effectively reduce the temperature of the workpiece surface by blowing air, the cooling element can start cooling based on the data from the inlet air temperature sensor to maintain the effect of reducing the temperature of the workpiece surface.

[0025] As an improvement, a workpiece measurement module is also included. This module is equipped with a coarseness sensor facing the workpiece to be coated, and is signal-connected to the main control module. Specifically, the coarseness sensor can be a visual signal sensor or other types of sensors capable of measuring the coarseness of the workpiece to be coated.

[0026] By adopting the above technical solution, the main control module can determine the thickness of the workpiece through the coarseness sensor. If the workpiece is coarse, there is no need to worry about the surface temperature being too high, and the distance between the spray gun and the workpiece can be reduced. When the workpiece is thin, such as with a diameter of less than 120mm, the main control module controls the spraying distance adjustment mechanism to adjust the distance between the spray gun and the workpiece according to the actual situation, so as to keep the surface temperature of the workpiece below the safe range.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] The main control module can detect excessively high surface temperature of the ceramic roller through temperature sensors and control the spraying distance adjustment mechanism to adjust the distance between the spray gun and the workpiece being coated, so that the surface temperature of the ceramic roller is reduced to a range that will not cause deformation of the ceramic roller or a decrease in the toughness of the mesh wall.

[0044] Implementation Case 1:

[0045] As shown in Figures 1-5, a distance adjustment device for ceramic roller spraying includes a spraying distance adjustment mechanism, a temperature sensor, and a main control module. The spraying distance adjustment mechanism is connected to the spray gun 4 and can adjust the distance between the spray gun 4 and the workpiece 5 to be coated. The temperature sensor is positioned facing the surface of the workpiece 5. The temperature sensor and the spraying distance adjustment mechanism are respectively connected to the main control module.

[0046] The spraying distance adjustment mechanism includes a mounting beam 10 mounted on a frame 1, which is parallel to the workpiece 5 to be coated. A transverse moving component 14 is slidably mounted on the mounting beam 10 along its length. A lifting mechanism is mounted on the transverse moving component 14. The lifting mechanism includes a limiting guide rail 12, a lifting motor 3, and a transmission belt 11. The limiting guide rail 12 is arranged vertically, and the transmission belt 11 is driven by the lifting motor 3 to move vertically.

[0047] The lifting mechanism is provided with a mounting base 15, which is slidably mounted on the limiting guide rail 12. The mounting base 15 is connected to the transmission belt 11. A spray gun 4 facing the workpiece 5 and a temperature sensor 2 are mounted on the mounting base 15.

[0048] As shown in Figure 5, when the lifting motor (3) drives the transmission belt to move, the mounting base is driven by the transmission belt (11) to move up and down. The lifting motor (3) driving the transmission belt to move can drive the mounting base to move up and down as a whole, thereby adjusting the distance between the spray gun 4 and the workpiece 5 to be coated. The above solution is one of the technical solutions that can be implemented. Other technical solutions that can effectively adjust the distance between the spray gun 4 and the workpiece 5 to be coated can also be used as alternatives. The temperature sensor is equipped with a temperature sensor for measuring the surface temperature of the workpiece 5 to be coated, specifically, the surface temperature after the ceramic roller plasma sprays the ceramic layer. Since both the spraying distance adjustment mechanism and the temperature sensor are connected to the main control module, when the main control module detects from the signal collected by the temperature sensor that the surface temperature of the ceramic roller after plasma spraying the ceramic layer is too high (based on experience, a temperature exceeding 150 degrees Celsius carries a significant risk of the mesh wall becoming too brittle and lacking toughness, or the ceramic roller deforming), the main control module can control the spraying distance adjustment mechanism to increase the distance between the spray gun 4 and the workpiece 5 being coated, thereby reducing the surface temperature of the ceramic roller after plasma spraying the ceramic layer and preventing the ceramic roller from deforming and the mesh wall from becoming less tough.

[0049] The main control module can detect excessively high surface temperature of the ceramic roller through the temperature sensor and control the spraying distance adjustment mechanism to adjust the distance between the spray gun 4 and the workpiece 5 to reduce the surface temperature of the ceramic roller to a range that will not cause deformation of the ceramic roller or a decrease in the toughness of the mesh wall.

[0050] It also includes a distance sensor, which is mounted on the spraying distance adjustment mechanism and positioned toward the workpiece 5 to be coated. The distance sensor is connected to the main control module via a signal connection.

[0051] The main control module can sense and record the distance data between the spray gun 4 and the workpiece 5 to be coated through the distance sensor, and can further calculate the most suitable distance between the spray gun 4 and the workpiece 5 to maintain the surface temperature within a safe range during plasma spraying for a certain type of workpiece 5 based on the distance data between the spray gun 4 and the workpiece 5 to be coated and the surface temperature data of the ceramic roller.

[0052] It also includes an air-blowing cooling module, which has an air outlet 7 facing the workpiece 5 to be coated, and an air pump 8 connected to the air outlet 7.

[0053] A wind speed sensor is installed at the air outlet 7, and the wind speed sensor is connected to the air pump 8 via a signal connection.

[0054] If the distance between the spray gun 4 and the workpiece 5 is too large, but the surface temperature of the workpiece 5 is still too high, the air cooling module can be activated, and air can be blown onto the surface of the workpiece 5 through the air outlet 7 to reduce the temperature. Alternatively, air can be blown onto the surface of the workpiece 5 through the air outlet 7 to reduce the temperature while keeping the surface temperature of the workpiece 5 within a safe range, in order to reduce the distance between the spray gun 4 and the workpiece 5.

[0055] The air-blowing cooling module is also equipped with a refrigeration element 9. The gas cooled by the refrigeration element 9 is blown out through the air outlet 7 by the air pump 8.

[0056] The use of cooling element 9 reduces the temperature of the airflow blown out of air outlet 7, further improving the cooling effect of the air-blowing cooling module.

[0057] The air-blowing cooling module is also equipped with a liquid nitrogen storage chamber, which can release liquid nitrogen and blow it out through the air outlet 7.

[0058] When it is necessary to improve the cooling effect of the air blowing cooling module, the liquid nitrogen storage tank can be controlled to release extremely cold nitrogen gas to blow air onto the surface of the workpiece 5 to reduce the temperature.

[0059] The air-blowing cooling module is also equipped with an inlet air temperature sensor, which is connected to the cooling element 9 via a signal.

[0060] When the factory temperature is too high and the ambient air is insufficient to effectively reduce the temperature of the surface of the workpiece 5 being coated, the cooling element 9 can start cooling based on the data from the inlet air temperature sensor to maintain the effect of reducing the surface temperature of the workpiece 5 being coated.

[0061] It also includes a workpiece measurement module, which is equipped with a coarseness sensor facing the workpiece 5 to be coated. The workpiece measurement module is signal-connected to the main control module. Specifically, the coarseness sensor can be a visual signal sensor or other types of sensors capable of measuring the coarseness of the workpiece 5 to be coated.

[0062] The main control module can determine the thickness of the workpiece 5 to be coated through the thickness sensor. If the workpiece 5 is relatively thick, there is no need to worry about the surface temperature being too high, and the distance between the spray gun 4 and the workpiece 5 can be reduced. When the workpiece 5 is relatively thin, such as with a diameter of less than 120mm, the main control module controls the spraying distance adjustment mechanism to adjust the distance between the spray gun 4 and the workpiece 5 according to the actual situation, so as to keep the surface temperature of the workpiece 5 within the safe range.

[0063] As shown in the figure, the temperature sensor that senses the surface temperature of the workpiece 5 and the distance sensor 6 that senses the distance between the spray gun 4 and the surface of the workpiece 5 are both set around the spray gun 4. Depending on the actual needs, the temperature sensor or the distance sensor 6 can also be set at an appropriate position on the frame 1.

[0064] As shown in Figure 3, the air-blowing cooling module has its air outlet facing the workpiece 5 being coated. Simply setting up this outlet and the air pump 8 is sufficient for basic air-blowing cooling. To increase the cooling capacity, a cooling element 9 or a storage tank for refrigerant such as liquid nitrogen can be added as needed. This allows for the use of electric cooling or the spraying of refrigerant to lower the temperature of the airflow from the outlet, thereby improving cooling capacity. Alternatively, increasing the power of the air pump 8 can increase the airflow velocity at the outlet, further enhancing cooling performance.

[0065] In summary, after reading this utility model document, those skilled in the art can make various other corresponding modifications based on the technical solution and concept of this utility model without creative mental effort. Different application scenarios are all within the scope of protection of this utility model.
