Description

Technical Field

[0001] The invention relates to the technical field of hardware processing, in particular to an ultrasonic cleaning device for processing hardware fasteners. Background Art

[0002] Ultrasonic cleaning devices for hardware, namely ultrasonic cleaning machines for hardware, are mainly used for surface treatment processes such as dust removal, oil removal, wax removal, rust removal, and debris removal for hardware. The core components of ultrasonic cleaning devices are ultrasonic cleaning tanks and ultrasonic generators. The inner wall at the bottom of the cleaning tank is equipped with ultrasonic transducer oscillators, which are used to convert the high-frequency and high-voltage signals generated by the ultrasonic generator into mechanical vibrations. The transducer and the vibration plate produce high-frequency resonance together, so that the solvent in the cleaning tank (such as water-based neutral detergents, municipal water or pure water, etc.) is subjected to ultrasonic waves to clean the dirt on the surface of the hardware. Metal gaskets play a variety of key roles in bolted connections, which indirectly enhance the tightness and stability of the connection. In the process of metal gasket processing, it is necessary to clean impurities and debris on the surface, and ultrasonic cleaning devices are required.

[0003] The ultrasonic cleaning device uses a combination of metal mesh belts and chains (metal mesh conveyor belts with chains on both sides) to move the metal gasket into the cleaning tank for cleaning, and then move it out of the cleaning tank for subsequent spray cleaning, drying, etc. The entire ultrasonic cleaning device is very long. During the cleaning process, the metal gasket first enters the ultrasonic cleaning tank, and most of the debris and impurities on its surface fall into the cleaning liquid inside the cleaning tank. After filtering in the cleaning tank with a filter pump and a filter tank, it can flow back into the cleaning tank to achieve multiple uses of the cleaning liquid. Other subsequent cleaning steps, such as spray cleaning, immersion cleaning and other facilities are also equipped with filter tanks. However, the surface of the metal gasket also carries large particles of impurities and metal chips. Since the metal gasket enters the ultrasonic cleaning tank first, most of the impurities will flow back to the filter pump with the liquid, especially the large particles of impurities and metal chips, which will cause the filter pump equipped in the cleaning tank to be easily blocked or even severely worn. At the same time, during the cleaning process, the metal gasket moves with the mesh belt, and its bottom surface part contacts the surface of the mesh belt, which is easy to be not cleaned properly and there are dead corners for cleaning. In addition, since the device is relatively long, the mesh belt and chain are relatively long, and the chain passes through many parts, the chain joints are easy to carry impurities generated by cleaning or subsequent incompletely dried water back into the ultrasonic cleaning tank, causing secondary pollution to the cleaning fluid.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0021] See also Figure 1-11, an ultrasonic cleaning device for processing hardware fasteners, including a frame 1, a cleaning tank body 2, a filter pump body 3, a filter tank 4, a sub-tank 5, a metal mesh belt 6 and a chain body 7 (the chain in the figure is only illustrated by a rectangular line head), a shell 8 is also bolted to one side of the frame 1, and the filter pump body 3 is bolted to the inside of the shell 8. The device also includes an infusion mechanism 15, a preliminary filter mechanism 16 and a blowing mechanism 17. A drive motor 9 is bolted to the rear side of the frame 1. An active roller 10 is rotatably connected to the surface of the frame 1 and is located near the drive motor 9. An auxiliary roller 13 is also rotatably connected to the surface of the frame 1. The number of active rollers 10 is single, and the number of auxiliary rollers 13 is several. The surfaces of the active rollers 10 and the auxiliary rollers 13 are provided with rubber transmission belts 11. Under the action of the active rollers 10 and the auxiliary rollers 13, the rubber transmission belt 11 is in an inverted trapezoidal shape, and the rubber transmission belt 11 can During normal operation, part of the rubber transmission belt 11 is located inside the cleaning tank body 2 and close to the surface of the metal mesh belt 6 located inside the cleaning tank body 2. A long box body 12 is bolted inside the cleaning tank body 2. Several electromagnets 18 are fixed inside the long box body 12. The material of the long box body 12 is metal material, specifically martensitic stainless steel, which can transmit magnetism. The bottom of the long box body 12 is flush with the bottom of the auxiliary roller 13 and fits below the surface of the rubber transmission belt 11. Several auxiliary sprockets 14 are also rotatably connected to the inside of the cleaning tank body 2, and the auxiliary sprockets 14 are meshed with the chain body 7. Under the action of the auxiliary sprockets 14, the direction of the chain body 7 inside the cleaning tank body 2 is restricted to prevent it from rising under the attraction of the electromagnet 18. The outlet end of the filter pump body 3 is connected with a return pipe 19, and the other end of the return pipe 19 is connected with the inlet of the filter tank 4.

[0022] When working, there is a motor on the device to drive the metal mesh belt 6 and the chain body 7 to move the metal gasket placed on the surface of the metal mesh belt 6 and gradually enter the inside of the cleaning tank body 2. The inner wall of the cleaning tank body 2 is connected to an ultrasonic transducer (which is a prior art and not shown in the figure), which generates ultrasonic waves on the inner wall of the cleaning tank body 2 and cooperates with the cleaning liquid inside the cleaning tank body 2 to clean the metal gasket on the surface of the metal mesh belt 6. At the same time, the drive motor 9 is turned on, and the output shaft of the drive motor 9 is connected to the active roller 10 through a gear transmission. The output shaft of the drive motor 9 drives the active roller 10 to rotate counterclockwise (with a gear). Figure 6The viewing angle is a positive viewing angle), and then the active roller 10 drives the auxiliary roller 13 to rotate through the rubber transmission belt 11, so that the upper half of the rubber transmission belt 11 runs in the left direction, and the lower half of the rubber transmission belt 11 follows the metal mesh belt 6 to run in the right direction. At the same time, the electromagnet 18 is turned on, which generates magnetic force around it. The magnetic force penetrates the rubber transmission belt 11 and attracts the metal gasket to move upward. At this time, the bottom of the metal gasket is out of contact with the surface of the metal mesh belt 6, thereby preventing the part of the metal gasket that contacts the metal mesh belt 6 from being effectively cleaned. The gasket is adsorbed on the surface of the rubber transmission belt 11 under the action of magnetic force. In the cleaning tank body 2, the top surface of the front half of the metal gasket is completely exposed to the liquid for cleaning, and the back half of the metal gasket temporarily follows the rubber transmission belt 11 to move, and the bottom is completely exposed to the liquid for cleaning, thereby reducing the cleaning dead corners. After that, the metal gasket continues to move with the metal mesh belt 6, and enters the subsequent spray cleaning, spray rinsing and drying links (these are all functions of the existing device and will not be described in detail). The metal gasket after cleaning and drying is unloaded from the end of the device.

[0023] The infusion mechanism 15 includes a connecting pipeline 151, an infusion pipeline 152 and a vertical cylinder 153. The connecting pipeline 151 is interconnected with the bottom of the cleaning pool body 2, the infusion pipeline 152 is interconnected with the connecting pipeline 151, and the other end of the infusion pipeline 152 is interconnected with the vertical cylinder 153. The interior of the vertical cylinder 153 is rotatably connected with a rotating column 154, and a spiral blade 155 is welded on the surface of the rotating column 154. In actual use, the height of the vertical cylinder 153 is lower than the height of the liquid level inside the cleaning pool body 2. According to the communicating vessel principle, part of the liquid inside the cleaning pool body 2 will automatically pass through the connecting pipeline 151 and the infusion pipeline 152 into the interior of the vertical cylinder 153, so that the interior of the vertical cylinder 153 is filled with liquid. The top end of the rotating column 154 extends to the top of the vertical cylinder 153 and is bolted with a crankshaft 156. The penetration of the rotating column 154 and the vertical cylinder 153 is connected by a The sealed bearing is fixed, which can rotate and prevent liquid from seeping out. A connecting plate 157 is bolted to one side of the top of the vertical cylinder 153. The surface of the connecting plate 157 is rotatably connected to a transverse column 158. The top of the crankshaft 156 is connected to the transverse column 158 through a bevel gear transmission. One end of the transverse column 158 is connected to the active roller 10 through a bevel gear transmission. The active roller 10 can drive the transverse column 158 to rotate through the bevel gear during rotation. The active roller 10 drives the transverse column 158 to rotate in the manner of a large gear driving a small gear, thereby speeding up. During the rotation of the transverse column 158, the crankshaft 156 can also be driven to rotate through the bevel gear. The crankshaft 156 drives the rotating column 154 and the spiral blade 155 below to rotate, and then the spiral blade 155 drives the liquid inside the vertical cylinder 153 to move upward. A connecting pipe 159 is also provided on one side of the vertical cylinder 153.

[0024] The preliminary filtering mechanism 16 includes a box body 161, a driving rod 162, a cross bar 163 and a vertical rod 164. The box body 161 is arranged inside the housing 8. One end of the driving rod 162 is rotatably connected to the crankshaft 156, and the other end of the driving rod 162 is rotatably connected to the cross bar 163. Both sides of the bottom of the cross bar 163 are bolted with vertical rods 164, and one side of the vertical rod 164 is bolted with a movable rod 165. One end of the movable rod 165 away from the vertical rod 164 passes through the interior of the box body 161 and is bolted with a push plate 1610. The movable rod 165 is connected to the box body 161. The movable rod 165 is connected to the through-hole of 61, which enables the movable rod 165 to slide back and forth. The crankshaft 156 can drive one end of the driving rod 162 to make a circular motion during the rotation, and then drive the cross bar 163 to make a reciprocating motion along the horizontal direction, and drive the movable rod 165 to make a reciprocating motion through the cross bar 163 and the vertical rod 164, and drive the push plate 1610 to make a reciprocating motion back and forth. The end of the connecting pipe 159 away from the vertical cylinder 153 penetrates into the interior of the box body 161. The preliminary filtering mechanism 16 also includes a filter screen 166 bolted thereto, and the filter screen 166 is connected to the box body. The bottom of the push plate 1610 is flush with the top of the filter screen 166. The liquid passing through the connecting pipe 159 is discharged from the outlet end of the connecting pipe 159 located inside the box body 161, and is filtered through the filter screen 166 to intercept large particles of impurities and metal chips in the refluxed liquid, so as to prevent the reflux of metal chips and large particles of impurities from causing blockage or serious wear of the filter pump body 3. At the same time, when large particles of impurities and metal chips accumulate on the surface of the filter screen 166, a collection box 167 is also provided on one side of the box body 161. The collection box 167 is a pull-out device. The push plate 1610 can push the impurities on the surface of the filter 166 into the collection box 167 while moving back and forth, so as to prevent large particles of impurities and metal chips from accumulating on the surface of the filter 166 and causing blockage. A first magnet 168 is also fixed on the surface of the collection box 167, and the collection box 167 is adsorbed and fixed to the box body 161 through the first magnet 168. A support plate 1614 is also bolted to the top of the box body 161, and the transverse column 158 is rotatably connected to the support plate 1614 to increase the rotational stability of the transverse column 158. Fig.12 As shown in the figure, the structure of the crankshaft 156 is shown. The upper part of the crankshaft 156 is a thicker metal column, and a long metal rod is welded to the bottom end. Figure 8The lower part of the crankshaft 156 is a smaller bevel gear, and it is a thicker metal column on the same axis as the metal column on the upper part. At the same time, a long metal rod is welded to the top of the lower metal column. The upper and lower parts of the crankshaft 156 adopt a similar design. The upper and lower long metal rods together constitute the extended end of the crankshaft 156. At the same time, the upper and lower long metal rods are connected by a short metal column in the middle, and the metal column and the upper and lower long metal rods are welded. Therefore, the upper and lower parts of the crankshaft 156 are fixed to each other, and there is no hinged connection between them, so that the crankshaft 156 can operate normally using a principle similar to the engine crank connecting rod, and the drive rod 162 is in a rotational connection with the short metal column in the middle part of the crankshaft 156.

[0025] The bottom of the box body 161 is connected to a lower tube 1615, and the other end of the lower tube 1615 is connected to the inlet end of the filter pump body 3. The liquid preliminarily filtered by the filter net 166 enters the filter pump body 3 after passing through the lower tube 1615, and then enters the filter tank 4 for further filtration after secondary filtration in the filter pump body 3. Finally, under the action of other supply pumps, it flows back to the cleaning pool body 2 (the above process is a mature technology in the existing device, and the specific process will not be described in detail).

[0026] One end of the connecting pipe 159 is also connected to a horizontal box 169, and a through groove 1613 is formed on the surface of the horizontal box 169. A blocking plate 1612 is slidably connected to the inner wall of the horizontal box 169. One end of the blocking plate 1612 extends to the outside of the box body 161 and is bolted to a fixing plate 1611. The fixing plate 1611 and the vertical rod 164 are bolted to each other. When the vertical rod 164 reciprocates back and forth, it can drive the blocking plate 1612 to move along the inner wall of the horizontal box 169. The wall moves horizontally back and forth, and the blocking plate 1612 moves together with the push plate 1610. When the push plate 1610 approaches the collection box 167, the blocking plate 1612 moves to the through groove 1613 to achieve temporary blocking, preventing the liquid discharged from the connecting tube 159 from directly falling on the surface of the push plate 1610 or behind the forward path of the push plate 1610. When the push plate 1610 is away from the collection box 167, the blocking plate 1612 is also away from the through groove 1613, thereby achieving normal discharge of the liquid.

[0027] The blowing mechanism 17 includes a cylinder 171, a piston 172, a movable column 173 and an air inlet 174. The cylinder 171 is in two groups and is bolted to both sides of the top of the vertical cylinder 153. The movable column 173 is bolted to one side of the cross bar 163 close to the cylinder 171. The movable column 173 is slidably connected to the inner wall of the entrance of the cylinder 171. The end of the movable column 173 away from the cross bar 163 is bolted to the piston 172. The blowing mechanism 17 also includes an air inlet 174 and an air outlet 179 which are connected and arranged at the upper and lower sides of the cylinder 171. The inner walls of the air inlet 174 and the air outlet 179 are respectively bolted with a first ring body 175 and a second ring body 1710. The inner diameter of the first ring body 175 is the same as the inner diameter of the second ring body 1710. The inner diameter of the air inlet 174 is the same as the inner diameter of the second ring body 1710. The wall is also bolted with a first sliding sleeve 176, the inner wall of the first sliding sleeve 176 is slidably connected with a first sliding rod 177, one end of the first sliding rod 177 is bolted with a first sealing plug 178, the inner wall of the air outlet 179 is also bolted with a second sliding sleeve 1711, the inner wall of the second sliding sleeve 1711 is slidably connected with a second sliding rod 1712, one end of the second sliding rod 1712 is bolted with a second sealing plug 1713, while the cross bar 163 reciprocates back and forth, the cross bar 163 drives the movable column 173 and the piston 172 to reciprocate, in the non-working state, the first sealing plug 178 contacts with the first sliding sleeve 176 under the action of gravity, the interior of the first ring body 175 is unobstructed, the second sealing plug 1713 contacts with the second sliding sleeve 1711, and the second ring The cylinder 1710 also remains unobstructed. At the same time, when the piston 172 moves toward the air inlet 174 and the air outlet 179, the volume of the cylinder 171 on the side close to the air inlet 174 and the air outlet 179 decreases, and the air pressure increases. Under the action of the air pressure, it pushes up the first sliding rod 177 and the first sealing plug 178, so that the first sealing plug 178 temporarily blocks the first ring body 175 to prevent air from being discharged. At the same time, the second sealing plug 1713 moves downward to keep the second ring body 1710 unobstructed. The bottom of the air outlet 179 is connected to the air supply pipe 1714, so that the internal gas of the cylinder 171 is discharged into the air supply pipe 1714. When the piston 172 moves in the direction away from the air inlet 174 and the air outlet 179, the cylinder The volume of the body 171 on this side increases, which allows the external air to push open the first sealing plug 178 under the action of the air pressure difference and pass through the first ring body 175 to enter the interior of the cylinder 171. At the same time, the air that has previously entered the air pipe 1714 can also push the second sliding rod 1712 and the second sealing plug 1713 to move upward, temporarily blocking the second ring body 1710 to prevent air backflow. In this way, during the reciprocating motion of the piston 172, air is continuously input into the air pipe 1714. The end of the air pipe 1714 away from the air outlet 179 is connected to a transverse pipe 1715, and the bottom of the transverse pipe 1715 is connected to a plurality of air outlet nozzles 1716, and the air outlet nozzles 1716 are aligned with the surface of the chain body 7.The air is discharged through the air delivery pipe 1714, the transverse pipe 1715 and the air outlet nozzle 1716, and blown to the surface of the chain body 7, preventing impurities or residual water from remaining at the chain hinge, and preventing the impurities brought by the continuously running chain from polluting the liquid inside the cleaning tank.
