Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for electroplating processing, and in particular to a protective structure for a column bearing used in the copper plating process of a printing roller. Background Technology

[0002] In the copper plating process of printing rollers, the protective effect of the column bearings directly affects the operating accuracy and service life of the equipment. In traditional copper plating processes, column bearings are often exposed to the copper plating solution environment: acidic plating solutions overflowing during the copper plating process and volatile corrosive gases can easily seep into the bearing, causing ball corrosion and grease failure. This not only increases the bearing rotation resistance and reduces the rotational accuracy of the printing roller, resulting in quality problems such as uneven copper plating layer thickness and rough surface, but also requires frequent shutdowns to replace the bearings, increasing maintenance costs and the risk of production interruption. Furthermore, impurities in the plating solution adhering to the bearing surface can exacerbate mechanical wear and even cause the printing roller to shift due to bearing jamming, thus restricting the stability and automation level of the copper plating process. The column bearing protection structure has significant shortcomings in the copper plating scenario of printing rollers. The protective structure is not compatible with the copper plating tank, and the installation and disassembly are inconvenient. As the copper plating of printing rollers develops towards high precision and long cycle production, the market urgently needs a bearing protection structure that can effectively isolate corrosive media and has both sealing and heat dissipation performance. It is necessary to solve the problems of bearing failure and copper plating quality fluctuation caused by plating solution erosion by integrating multi-layer sealing, corrosion-resistant materials and heat dissipation design.

[0003] In existing technologies, the column bearing protection structure used in the copper plating process of printing rollers uses simple sealing covers for protection. However, in actual use, due to poor water vapor penetration and limited protection against corrosion from acidic plating solutions, the lack of a sealing design makes it impossible to meet the sealing requirements when the printing roller rotates at high speed. This easily leads to plating solution leakage, corrosion of the bearing, bearing damage, poor rotation, and even affects the electroplating quality and equipment life. Therefore, we propose a column bearing protection structure for the copper plating process of printing rollers. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a column bearing protection structure for the copper plating process of printing rollers. Multiple protective structures are set on the column that holds the printing roller to rotate, including: a sealing ring is set at the connection between the column and the printing roller to form the first sealing barrier to prevent the copper acid solution from directly entering the interior of the column; and a guide groove is set on the outside of the first protective ring to guide the small amount of leaked copper acid solution to the collection container to avoid the accumulation of copper acid solution.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A protective structure for a column bearing in a copper plating process of a printing roller includes a connecting mechanism, a sealing mechanism fixedly connected to the left and right ends of the connecting mechanism, and a drainage mechanism fixedly installed at the left and right ends of the sealing mechanism.

[0007] The diversion mechanism includes a protective ring with connection ports at the center of both ends. A diversion groove is provided on the inner side of the inner end of the protective ring. By setting a sealing ring at the connection between the column and the roller, a first sealing barrier is formed to prevent the copper acid solution from directly entering the inside of the column. A diversion groove is provided on the outer side of the first protective ring to divert a small amount of leaked copper acid solution to a collection container, preventing the copper acid solution from accumulating, improving the sealing effect of the device, and enhancing the device's protection function for the bearing.

[0008] Furthermore, the sealing mechanism includes a column body, a sealing ring is provided at the middle of the front end of the column body, the sealing ring is fixedly installed on the inner side of the protective sleeve, a fixing rod is fixedly connected to the front end of the protective sleeve, and a connecting sleeve is connected to the front end of the fixing rod. By setting the sealing ring, the sealing performance during connection is improved, preventing the leakage of acid copper solution from corroding the bearing, and improving the protective performance of the device.

[0009] Furthermore, the connecting mechanism includes a printing roller body, and connecting rods are fixedly provided on the left and right sides of the upper end of the printing roller body. By setting connecting rods fixedly on the left and right sides of the upper end of the printing roller body, the printing roller body can be easily fixed and limited, thereby improving the protection performance of the device for the core area.

[0010] Furthermore, the protective ring is fixedly installed between the protective sleeve and the column body. By setting the protective ring to be fixedly installed between the protective sleeve and the column body, the protective sleeve and the column body are connected, and the printing roller body is fixedly connected, which facilitates the copper plating work and improves the convenience and protection of the device during use.

[0011] Furthermore, the connecting rod is fixedly connected to the inner side of the inner end of the connecting sleeve.

[0012] Furthermore, the protective ring has a disc-shaped structure with openings at both ends smaller than those in the middle.

[0013] Furthermore, the number of the guide channels is several, and the several guide channels are rectangular grooves arranged in parallel.

[0014] Furthermore, the number of the protective ring, protective sleeve, and connecting sleeve are all two.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By setting a sealing ring, the sealing performance during connection is improved, preventing the leakage of copper acid solution from corroding the bearing and improving the protection performance of the device. By setting a sealing ring at the connection between the column and the roller, the first sealing barrier is formed, preventing the copper acid solution from directly entering the inside of the column.

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] Reference Figure 1-5As shown, a column bearing protection structure for copper plating process of printing roller is provided in a preferred embodiment of this utility model. It includes a connecting mechanism 1, a sealing mechanism 2 is fixedly connected to the left and right ends of the connecting mechanism 1, and a diversion mechanism 3 is fixedly installed on the left and right ends of the sealing mechanism 2.

[0027] The diversion mechanism 3 includes a protective ring 301. Connecting ports 302 are provided at the center of both the front and rear ends of the protective ring 301. A guide groove 303 is provided on the inner side of the inner end of the protective ring 301. The protective ring 301 has a disc-shaped structure with openings at both ends smaller than the number of guide grooves 303 in the middle. These guide grooves 303 are rectangular grooves arranged in parallel. By providing the guide grooves 303, the small amount of leaked copper acid solution is diverted to a collection container, preventing the accumulation of copper acid solution and further improving the protective performance of the device. There are two protective rings 301, two protective sleeves 203, and two connecting sleeves 205. By setting two protective rings 301, two protective sleeves 203, and two connecting sleeves 205, protective devices are installed at both ends of the printing roller body 101 that need to be connected. The design of the protective ring 301 makes the bearings inside the printing roller body 101 less susceptible to acid corrosion, improving the protective performance of the device during use. By setting the protective ring 301 to a disc-shaped structure with the openings at both ends smaller than the middle, acid entering at the two ends will collect in the center of the protective ring 301 under the action of gravity and centrifugal force, making it less likely to enter the interior of the printing roller body 101, thus improving the protective performance of the device. By setting a sealing ring 202 at the connection between the column and the printing roller, a first sealing barrier is formed to prevent copper acid solution from directly entering the interior of the column. A guide groove 303 is set on the outside of the first protective ring 301 to guide a small amount of leaked copper acid solution to a collection container, avoiding the accumulation of copper acid solution, improving the sealing effect of the device, and enhancing the device's protection function for the bearings.

[0028] Reference Figure 1-3 As shown, the sealing mechanism 2 includes a column body 201. A sealing ring 202 is provided at the middle of the front end of the column body 201. The sealing ring 202 is fixedly installed on the inner side of the protective sleeve 203. A fixing rod 204 is fixedly connected to the front end of the protective sleeve 203. A connecting sleeve 205 is connected to the front end of the fixing rod 204. By setting the sealing ring 202, the sealing performance during connection is improved, preventing the leakage of copper acid solution from corroding the bearing and improving the protective performance of the device.

[0029] Reference Figure 1-2 As shown, the connecting mechanism 1 includes a printing roller body 101. Connecting rods 102 are fixedly arranged on the left and right sides of the upper end of the printing roller body 101. The connecting rods 102 are fixedly connected to the inner side of the inner end of the connecting sleeve 205. By setting the connecting rods 102 fixedly arranged on the left and right sides of the upper end of the printing roller body 101, the printing roller body 101 can be easily fixed and limited, which improves the protection performance of the device for the core area.

[0030] Reference Figure 2-5As shown, the protective ring 301 is fixedly installed between the protective sleeve 203 and the column body 201. By setting the protective ring 301 to be fixedly installed between the protective sleeve 203 and the column body 201, the protective sleeve 203 and the column body 201 are connected, and the printing roller body 101 is fixedly connected, which facilitates the copper plating work and improves the convenience and protection of the device during use.

[0031] Specific implementation process: First, assemble the device. At the connection between the column body 201 and the printing roller body 101, select a suitable sealing ring 202 according to the design dimensions. Use professional tools to embed the sealing ring 202 into the pre-processed sealing groove, ensuring that the sealing ring 202 is completely embedded without twisting or damage, so that it fits tightly with the column body 201 and the printing roller body 101, thereby forming the first sealing barrier. On the surface of the column body 201 outside the first sealing ring 202, a guide groove 303 is opened by mechanical processing. The shape, size, and tilt angle of the guide groove 303 need to be carefully designed to ensure that the copper acid solution can flow smoothly along the groove. After the sealing ring 202 and the guide groove 303 are installed, the column body 201 and the printing roller body 101 are assembled as a whole. During the assembly process, the installation position and connection tightness of each component are carefully checked. After the assembly is completed, a trial run is conducted to observe whether there are any abnormalities during the rotation of the column body 201, ensuring that the protective structure can work normally. In the copper plating process of the printing roller, the copper acid solution will come into contact with the surface of the printing roller for electroplating. At this time, the first sealing barrier - the O-ring 202 or the lip seal 202 plays a key role. With its good elasticity and sealing performance, it fits tightly with the connection between the column and the printing roller, effectively preventing the copper acid solution from directly entering the interior of the column and preventing the solution from corroding and damaging key components such as the column bearing. When a very small amount of copper acid solution leaks and breaks through the first sealing barrier, the guide groove 303 immediately comes into play. Because the guide channel 303 has a specific tilt angle, the leaked copper acid solution will flow along the channel of the guide channel 303 towards the collection container under the action of gravity, thereby achieving multiple effective protections for the column bearing and ensuring the stable and efficient operation of the copper plating process of the printing roller.
