Description

Technical Field

[0001] This invention belongs to the field of electrode spraying technology, specifically an electrode spraying device. Background Technology

[0002] An alkaline electrolyzer is a commonly used device for producing hydrogen through water electrolysis, and one of its core components is the electrode. The main function of the electrode in an alkaline electrolyzer is to catalyze the decomposition of water molecules during electrolysis to produce hydrogen and oxygen. The electrode material for an alkaline electrolyzer is usually nickel mesh. During the manufacturing process, an oxide coating or catalyst coating needs to be sprayed onto the nickel mesh using a spraying device to improve the efficiency of hydrogen production through water electrolysis.

[0003] Patent CN117463519A discloses an automatic spraying device for mesh electrodes, including a base, a turntable, mounting seats, and mounting rods. The turntable is rotatably mounted on the base, and four sets of mounting seats are installed at equal angles on the turntable. The mounting seats are provided with mounting rods for limiting the mesh electrode body. This solution limits the mesh electrode body to the mounting seats by placing it on the mounting seats and applying pressure, thus preventing the mesh electrode body from being blown over by airflow or falling off the worktable. By driving the extrusion rod to one end near the protrusion, the protrusion is extruded outward from the first connecting groove until the protrusion is completely separated from the first connecting groove. At this time, the fixing block enters the fixing groove with the movement of the connecting rod, releasing the fixing of the mounting plate, thereby facilitating the replacement of the mesh electrode body by the operator.

[0004] In the above-mentioned scheme, only one side of the mesh electrode body can be sprayed at a time. Single-sided spraying will cause the oxide or catalyst to be unevenly distributed on the entire electrode surface, thus failing to guarantee the consistency of electrode performance. If two-sided spraying is performed, the mesh electrode body needs to be flipped over. Before flipping, the previously sprayed surface needs to be dried, which will waste a lot of time and reduce the efficiency of electrode spraying. Therefore, the present invention provides an electrode spraying device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The electrode spraying device of the present invention includes a base and two sets of chains. A bracket is fixedly installed on the base. Two sets of transmission shafts are rotatably installed inside the bracket. Two sets of sprockets are installed on each set of transmission shafts. Each set of chains meshes with two sets of sprockets. Several sets of chain plate assemblies are distributed on the outer ring of the chains. A mounting frame and a drying oven are fixedly installed on the bracket in sequence. Two sets of electric arc spraying guns are fixedly installed on the bracket. A drive shaft is rotatably installed at one end of the bracket. The chain plate assembly includes a plate body. Two sets of chains are fixedly connected to both ends of the plate body. The drive shaft is rotatably connected to the plate body. A rotating seat is rotatably installed on the plate body. A placement rod is fixedly installed on the rotating seat. Four sets of support feet are installed at equal angles on the outer ring of the placement rod.

[0007] The mesh electrode body is coated by two sets of arc spray guns and then dried in a drying oven, thereby improving the coating efficiency of the mesh electrode body.

[0008] Preferably, a rubber sleeve is fitted at the end of the drive shaft, and the rubber sleeve is in close contact with a set of plates;

[0009] By using rubber sleeves, direct contact between the drive shaft and the plate / rotary seat is avoided, thereby reducing wear between the drive shaft and the plate / rotary seat and increasing their service life.

[0010] Preferably, the chain plate assembly further includes a movable shaft, a placement rod inserted into the movable shaft, a spring sleeved on the placement rod, four sets of fixing members distributed at equal angles around the end of the movable shaft, four sets of clearance holes opened at equal angles on the placement rod, the four sets of fixing members respectively hinged to the four sets of clearance holes, four sets of clearance grooves opened at equal angles on the end of the movable shaft, rectangular grooves opened on the fixing members, one end of the fixing member located in the clearance groove, a pin is provided in each of the four sets of clearance grooves, the pin is located in the rectangular groove, a roller is rotatably installed on the other end of the movable shaft, a guide ring is provided in the bracket, the two ends of the guide ring are respectively sleeved on two sets of transmission shafts, the roller rotatably connects to the inner ring of the guide ring, the inner ring of the guide ring is composed of a first ring surface, a second ring surface, and an inclined surface;

[0011] The movable shaft drives four sets of pins to slide along four sets of rectangular grooves, causing the four sets of fixing parts to rotate. The fixing parts rotate out of the clearance holes until the fixing parts press against the mesh electrode body, so that the mesh electrode body is clamped between the fixing parts and the support feet, and the mesh electrode body is fixed on the placement rod, thereby ensuring that the placement rod and the mesh electrode body rotate synchronously, so that the mesh electrode body is sprayed more evenly.

[0012] Preferably, a stacking mechanism for placing the mesh electrode body is provided below the support. The stacking mechanism includes two sets of fixing plates, which are symmetrically installed on both sides below the support. Several sets of rollers are rotatably installed on the inner side of the fixing plates. A stacking barrel is provided below one end of the fixing plate, and a fixed seat is provided below the stacking barrel. The two sets of fixing plates form a feeding port between their ends. The stacking barrel is located directly below the feeding port. A guide groove is opened at the lower end of the stacking barrel, and a guide rail is provided on the fixed seat. The guide rail is slidably connected to the guide groove.

[0013] When the mesh electrode body moves to the discharge port, it will fall into the stacking bin through the discharge port. The above operation is repeated cyclically, and the mesh electrode bodies will fall into the stacking bin one by one, realizing the automatic collection of the mesh electrode bodies. This not only improves the automation rate of the device, but also improves the efficiency of sorting the mesh electrode bodies.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The mesh electrode body is sprayed with two sets of electric arc spray guns and dried in a drying oven, thereby improving the spraying efficiency of the mesh electrode body.

[0016] 2. After the mesh electrode body is placed on the chain plate assembly, the spring inside the chain plate assembly is in a compressed state, and the roller on the chain plate assembly is on the first ring surface. When several sets of chain plate assemblies are driven to make circular motion, the roller will roll from the first ring surface to the second ring surface. Under the action of the spring rebound force, the movable shaft along with the roller moves towards the second ring surface, so that the roller contacts the second ring surface. At the same time, the movable shaft drives the four sets of pins to slide along the four sets of rectangular grooves respectively, so that the four sets of fixing parts rotate and the fixing parts rotate out of the clearance hole until the fixing parts squeeze the mesh electrode body, so that the mesh electrode body is clamped between the fixing parts and the support foot, and the mesh electrode body is fixed on the placement rod, thereby ensuring that the placement rod and the mesh electrode body rotate synchronously, so that the mesh electrode body is sprayed more evenly.

[0017] 3. After spraying, the mesh electrode body enters the drying chamber for drying. During the movement of the mesh electrode body in the drying chamber, the rollers roll along the second annular surface. At the same time, the mesh electrode body is clamped between the fixing parts and the support feet. When the mesh electrode body moves out of the drying chamber, the rollers will roll onto the inclined surface. The rollers will be squeezed by the inclined surface, causing the rollers to drive the movable shaft to compress the spring, causing the four sets of fixing parts to return to the placement rod. This continues until the rollers roll onto the first annular surface, releasing the fixing of the mesh electrode body and allowing it to fall onto the rollers. At the same time, the placement rod drives the mesh electrode body to move along the rollers towards the discharge port. When the mesh electrode body reaches the discharge port, it will fall into the stacking bin through the discharge port. The above operation is repeated, and the mesh electrode bodies will fall into the stacking bin one by one, realizing the automatic collection of the mesh electrode bodies. This not only improves the automation rate of the device but also improves the efficiency of sorting the mesh electrode bodies. Attached Figure Description

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example 1

[0029] like Figures 1 to 3 As shown in the embodiment of the present invention, an electrode spraying device includes a base 1 and two sets of chains 5. A bracket 2 is fixedly installed on the base 1. Two sets of transmission shafts 3 are rotatably installed inside the bracket 2. Two sets of sprockets 4 are installed on each set of transmission shafts 3. Each set of chains 5 meshes with two sets of sprockets 4. Several sets of chain plate assemblies 6 are distributed on the outer ring of the chains 5. A mounting frame 7 and a drying oven 8 are fixedly installed on the bracket 2 in sequence. Two sets of arc spraying guns 9 are fixedly installed on the bracket 2. A drive shaft 10 is rotatably installed at one end of the bracket 2. The chain plate assembly 6 includes a plate body 601. Two sets of chains 5 are fixedly connected to both ends of the plate body 601. The drive shaft 10 is rotatably connected to the plate body 601. A rotating seat 602 is rotatably installed on the plate body 601. A placement rod 603 is fixedly installed on the rotating seat 602. Four sets of support feet 604 are installed at equal angles on the outer ring of the placement rod 603.

[0030] Specifically, a resistance wire heater 81 is installed on the drying oven 8. The resistance wire heater 81 can heat the inside of the drying oven 8. When it is necessary to spray the mesh electrode body, the mesh electrode body is placed on an empty set of placement rods 603, and the four sets of support feet 604 on the placement rods 603 support the mesh electrode body, so that the mesh electrode body is placed on the chain plate assembly 6. Then, a set of transmission shafts 3 is driven to rotate by a motor, and the motor used to drive the drive shaft 10 is in a de-energized state. The set of transmission shafts 3 drives two sets of sprockets 4 to rotate. The sprockets 4 drive the chain 5 and several sets of chain plate assemblies 6 to perform circular motion. Below is attached Figure 2The middle arrow indicates the direction of circular motion. Simultaneously, several sets of moving plates 601 drive the drive shaft 10 to rotate until the mesh electrode body moves directly below the mounting bracket 7. At this point, two sets of arc spray guns 9 are angled towards the top and bottom surfaces of the mesh electrode body, and the outer ring of the drive shaft 10 contacts the rotating seat 602. Then, the motor driving the drive shaft 10 is energized, causing it to rotate. The rotating drive shaft 10 drives the rotating seat 602, along with the placement rod 603, support foot 604, and mesh electrode body, to rotate together. Simultaneously, the two sets of arc spray guns 9 are activated to spray the top and bottom surfaces of the mesh electrode body, achieving coating of both surfaces. After the mesh electrode body is coated, the arc spray guns 9 are paused, and the drive shaft 10 is activated. The motor of drive shaft 10 is de-energized, but continues to drive several sets of chain plate assemblies 6 to perform circular motion until they are directly below the next set of moving mounting brackets 7. During this process, the sprayed mesh electrode body will move into the drying chamber 8. Since the drying chamber 8 is heated by the resistance wire heater 81, the sprayed material on the mesh electrode body is evaporated, thus drying the mesh electrode body. After drying, the mesh electrode body will automatically fall onto the base 1 as the chain plate assembly 6 performs circular motion, thus unloading the mesh electrode body. Then, the above operation is repeated. Compared with the prior art, spraying the mesh electrode body with two sets of electric arc spray guns 9 and drying the mesh electrode body with the drying chamber 8 improves the spraying efficiency of the mesh electrode body.

[0031] Furthermore, a rubber sleeve 11 is fitted at the end of the drive shaft 10, and the rubber sleeve 11 is in close contact with a set of plates 601.

[0032] Specifically, by setting the rubber sleeve 11, direct contact between the drive shaft 10 and the plate 601 and the rotating seat 602 is avoided, thereby reducing wear between the drive shaft 10 and the plate 601 and the rotating seat 602 and improving the service life of the drive shaft 10 and the plate 601 and the rotating seat 602.

[0033] like Figures 4 to 6As shown, the chain plate assembly 6 also includes a movable shaft 605, which is inserted into a placement rod 603. A spring 606 is sleeved on the placement rod 603. Four sets of fixing members 607 are evenly distributed around the end of the movable shaft 605. Four sets of clearance holes 6031 are evenly formed on the placement rod 603. The four sets of fixing members 607 are respectively hinged to the four sets of clearance holes 6031. Four sets of clearance grooves 6052 are evenly formed on the end of the movable shaft 605. Rectangular grooves 6071 are formed on the fixing members 607. One end of 607 is located in the clearance groove 6052. Each of the four clearance grooves 6052 is provided with a pin 6053. The pin 6053 is located in the rectangular groove 6071. The other end of the movable shaft 605 is rotatably mounted with a roller 6051. The bracket 2 is provided with a guide ring 201. The two ends of the guide ring 201 are respectively fitted onto two sets of transmission shafts 3. The roller 6051 is rotatably connected to the inner ring of the guide ring 201. The inner ring of the guide ring 201 is composed of a first annular surface 2011, a second annular surface 2012, and an inclined surface 2013.

[0034] Specifically, when the drive shaft 10 drives the rotating seat 602, along with the placement rod 603, support foot 604, and mesh electrode body to rotate together, the rotation of the mesh electrode body is achieved through the friction between the support foot 604 and the mesh electrode body. However, the friction between the support foot 604 and the mesh electrode body is limited, causing the rotation between the placement rod 603 and the mesh electrode body to be out of sync, resulting in uneven coating of the mesh electrode body. Therefore, after the mesh electrode body is placed on the chain plate assembly 6, the spring 606 inside the chain plate assembly 6 is in a compressed state, and the roller 6051 on the chain plate assembly 6 is on the first annular surface 2011. When several sets of chain plate assemblies 6 are driven to perform circular motion, the roller 6051 will move from the first annular surface 2011. Rolling towards the second annular surface 2012, the movable shaft 605, along with the roller 6051, moves towards the second annular surface 2012 under the rebound force of the spring 606. The roller 6051 contacts the second annular surface 2012. At the same time, the movable shaft 605 drives the four sets of pins 6053 to slide along the four sets of rectangular grooves 6071, causing the four sets of fixing parts 607 to rotate. The fixing parts 607 rotate out of the clearance hole 6031 until the fixing parts 607 press against the mesh electrode body, so that the mesh electrode body is clamped between the fixing parts 607 and the support foot 604, and the mesh electrode body is fixed on the placement rod 603. This ensures that the placement rod 603 and the mesh electrode body rotate synchronously, making the spraying of the mesh electrode body more uniform. Example 2

[0035] like Figure 7 and Figure 8As shown in the comparative embodiment one, another embodiment of the present invention is as follows: A stacking mechanism 12 for placing the mesh electrode body is provided below the support 2. The stacking mechanism 12 includes two sets of fixing plates 121, which are symmetrically installed on both sides below the support 2. Several sets of rollers 122 are rotatably installed on the inner side of the fixing plates 121. A stacking barrel 123 is provided below one end of the fixing plate 121. A fixing seat 124 is provided below the stacking barrel 123. The two sets of fixing plates 121 are connected at one end to form a discharge port 125. The stacking barrel 123 is located directly below the discharge port 125. A guide groove 126 is opened at the lower end of the stacking barrel 123. A guide rail 127 is provided on the fixing seat 124. The guide rail 127 is slidably connected to the guide groove 126.

[0036] Specifically, the coated mesh electrode body will fall onto the base 1, requiring workers to collect it before proceeding to the next step. Because the position of the mesh electrode body on the base 1 is not fixed, collecting it is inconvenient and affects work efficiency. Therefore, the coated mesh electrode body will enter the drying chamber 8 for drying. During its movement within the drying chamber 8, the roller 6051 will roll along the second annular surface 2012, while the mesh electrode body is held between the fixing member 607 and the support foot 604. After the mesh electrode body moves out of the drying chamber 8, the roller 6051 will roll onto the inclined surface 2013, and the roller 6051 will be subjected to the force of the inclined surface 2013. The compression causes the roller 6051 to drive the movable shaft 605 to compress the spring 606, causing the four sets of fixing parts 607 to return to the placement rod 603 until the roller 6051 rolls onto the first annular surface 2011, releasing the fixing of the mesh electrode body and allowing the mesh electrode body to fall onto the roller 122. At the same time, the placement rod 603 drives the mesh electrode body to move along the roller 122 towards the discharge port 125. When the mesh electrode body moves to the discharge port 125, it will fall into the stacking bin 123 through the discharge port 125. The above operation is repeated, and the mesh electrode bodies will fall into the stacking bin 123 one by one, realizing the automatic collection of the mesh electrode bodies. This not only improves the automation rate of the device, but also improves the efficiency of sorting the mesh electrode bodies.

[0037] Working principle: The mesh electrode body is placed on an empty set of placement rods 603, and the four sets of support feet 604 on the placement rods 603 support the mesh electrode body, thus placing the mesh electrode body on the chain plate assembly 6. Then, a set of transmission shafts 3 is driven to rotate by a motor, while the motor driving the drive shaft 10 is in a de-energized state. The set of transmission shafts 3 drives two sets of sprockets 4 to rotate, and the sprockets 4 drive the chain 5 and several sets of chain plate assemblies 6 to perform circular motion. At the same time, the moving plates 601 drive the drive shaft 10 to rotate until the mesh electrode body moves directly under the mounting frame 7. At this time, the two sets of arc spray guns 9 are respectively diagonally pointing to the upper and lower surfaces of the mesh electrode body, and the outer ring of the drive shaft 10 is in contact with the rotating seat 602. Then, the motor driving the drive shaft 10 is energized, and the motor drives the drive shaft 10 to rotate. The rotating drive shaft 10 drives the rotating seat. 602, together with the placement rod 603, support foot 604, and mesh electrode body, rotates together. At the same time, two sets of electric arc spray guns 9 are started to spray the upper and lower surfaces of the mesh electrode body, thus achieving spraying of the upper and lower surfaces of the mesh electrode body. After the mesh electrode body is sprayed, the spraying of the electric arc spray guns 9 is stopped, and the motor driving the drive shaft 10 is de-energized. Several sets of chain plate assemblies 6 continue to drive in a circular motion until they are directly under the next set of moving mounting brackets 7. During this process, the sprayed mesh electrode body will move into the drying chamber 8. Since the drying chamber 8 is heated by the resistance wire heater 81, the sprayed material on the mesh electrode body is evaporated, thus achieving the drying of the mesh electrode body. After drying, the mesh electrode body will automatically fall onto the base 1 as the chain plate assembly 6 moves in a circular motion, thus achieving the unloading of the mesh electrode body. Then the above operation is repeated.

[0038] After the mesh electrode body is placed on the chain plate assembly 6, the spring 606 inside the chain plate assembly 6 is in a compressed state, and the roller 6051 on the chain plate assembly 6 is on the first annular surface 2011. When several sets of chain plate assemblies 6 are driven to perform circular motion, the roller 6051 will roll from the first annular surface 2011 towards the second annular surface 2012. Under the rebound force of the spring 606, the movable shaft 605, together with the roller 6051, moves towards the second annular surface 2012, causing the roller 6051 to engage with... When the second annular surface 2012 is touched, the movable shaft 605 drives the four sets of pins 6053 to slide along the four sets of rectangular grooves 6071 respectively, causing the four sets of fixing parts 607 to rotate, and the fixing parts 607 rotate out of the clearance hole 6031 until the fixing parts 607 press against the mesh electrode body, so that the mesh electrode body is clamped between the fixing parts 607 and the support foot 604, and the mesh electrode body is fixed on the placement rod 603, thereby ensuring that the placement rod 603 and the mesh electrode body rotate synchronously;

[0039] After being sprayed, the mesh electrode body enters the drying chamber 8 for drying. During its movement within the drying chamber 8, the roller 6051 rolls along the second annular surface 2012. Simultaneously, the mesh electrode body is held between the fixing member 607 and the support foot 604. Once the mesh electrode body exits the drying chamber 8, the roller 6051 rolls onto the inclined surface 2013, where it is compressed. This compression causes the roller 6051 to drive the movable shaft 605, compressing the spring 606 and causing the four sets of fixing members 607 to... Returning to the placement rod 603, until the roller 6051 rolls onto the first annular surface 2011, the fixing of the mesh electrode body is released, allowing the mesh electrode body to fall onto the roller 122. At the same time, the placement rod 603 drives the mesh electrode body to move along the roller 122 towards the discharge port 125. When the mesh electrode body moves to the discharge port 125, it will fall into the stacking bin 123 through the discharge port 125. The above operation is repeated, and the mesh electrode bodies will fall into the stacking bin 123 one by one, realizing the automatic collection of the mesh electrode bodies.
