Abstract
Description
Technical Field
[0001] This utility model relates to the field of electroplating equipment technology, specifically to a cleaning device for electroplating pipe fittings. Background Technology
[0002] Electroplating, as an important surface treatment technology, deposits metal or alloy coatings on the surface of a substrate through electrolysis, significantly improving the material's corrosion resistance, wear resistance, conductivity, and aesthetics. Its core principle lies in using an applied current to drive metal ions in the electroplating solution to be reduced on the cathode (the workpiece to be plated), forming a uniform and dense metal layer. Simultaneously, the anode (the plating metal or inert material) dissolves to replenish the ion concentration, maintaining electrolytic equilibrium. From a process flow perspective, electroplating consists of three stages: pretreatment, electroplating, and post-treatment. Pretreatment, through steps such as degreasing, pickling, and activation, ensures the cleanliness of the substrate surface and enhances the adhesion of the coating. When pre-treating tubular workpieces, the tubing is typically placed in a cleaning tank and cleaned with a cleaning solution.
[0003] However, the above cleaning methods are only suitable for pipes with small diameters and lengths. They are difficult to use for pipes with large diameters and lengths. Manual cleaning of the inner walls of the pipes is usually required, which is costly and inefficient. Utility Model Content

Several nozzles are fixedly connected to the bottom of the spray pipe.
[0007] Furthermore, several clamping plates are evenly and parallelly arranged around the inner axis of the drum. Spring telescopic rods are vertically and fixedly connected between the two ends of the clamping plates and the inner wall of the drum.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4The cleaning equipment for pipe electroplating in this embodiment includes a frame 1. Several sets of rollers 2 are symmetrically arranged on both sides and the middle of the top of the frame 1. Rollers 3 are rotatably connected between the rollers 2. A cleaning mechanism 10 is installed inside the rollers 3 for cleaning the inner wall of the pipe. The cleaning mechanism 10 includes a spray pipe 1003, which is arranged parallel to the top inner side of the roller 3. A lifting frame 1001 is slidably connected to the end side wall of the frame 1. A lifting mechanism is installed at the bottom of the lifting frame 1001 to drive it to move up and down. The spray pipe 1003 is fixedly connected to the top of the lifting frame 1001. The side of the lifting frame 1001 away from the roller 3... A liquid inlet pipe 1002 is fixedly connected to the side wall, and the liquid inlet pipe 1002 is connected to the spray pipe 1003. Several nozzles 1004 are fixedly connected to the bottom of the spray pipe 1003. Several clamping plates 1005 are evenly and parallelly arranged around the axis inside the roller 3. Spring telescopic rods 1008 are fixedly connected vertically between the two ends of the clamping plate 1005 and the inner wall of the roller 3. Several feeding wheels 1006 are rotatably connected to the side wall of the clamping plate 1005 away from the inner wall of the roller 3. An inclined surface 1007 is provided at the end of each clamping plate 1005 away from the lifting frame 1001. A stop block 1009 is fixedly connected to the end of each clamping plate 1005 facing the lifting frame 1001. During cleaning, first adjust the height of the spray pipe 1003 according to the diameter of the pipe fitting. During adjustment, the lifting mechanism drives the lifting frame 1001 to rise and fall on the side wall of the frame 1. As the lifting frame 1001 moves, it causes the spray pipe 1003 to move inside the roller 3 until the distance between the spray pipe 1003 and the axis of the roller 3 is less than the radius of the pipe fitting. Then, install the pipe fitting inside the roller 3. During installation, insert the end of the pipe fitting along the inclined surface 1007 of the clamping plate 1005 into the roller 3, ensuring that the spray pipe 1003 extends into the interior of the pipe fitting. At this time, the ends of the clamping plate 1005... The spring telescopic rod 1008 shortens, generating an elastic force in the opposite direction on the clamping plate 1005, thereby clamping and fixing the pipe between the clamping plates 1005; during the clamping process, the feeding roller 1006 can reduce the friction between the pipe and the clamping plate 1005, and the pipe is inserted into the inside of the roller 3 until the end of the pipe abuts against the stop block 1009 at the other end of the clamping plate 1005, thereby limiting and fixing the pipe; then, cleaning fluid is introduced into the spray pipe 1003 through the liquid inlet pipe 1002, so that the cleaning fluid is sprayed out along the nozzle 1004 to the inner wall of the pipe, cleaning the inner wall of the pipe.
[0022] The height of the end of the roller 3 away from the lifting frame 1001 is higher than the height of the end facing the lifting frame 1001. A liquid collection tank 1010 is provided at the bottom outer side of the lower end of the roller 3, and the liquid collection tank 1010 is fixedly connected to the frame 1. During cleaning, the cleaning fluid flows into the liquid collection tank 1010 along the bottom end of the inclined pipe, realizing the recycling of the cleaning fluid.
[0023] A mounting bracket 5 is fixedly connected to the top center of the frame 1. A motor 6 is fixedly connected to the top of the mounting bracket 5. A drive gear 7 is fixedly connected to the shaft of the motor 6. A driven gear 8 is fixedly connected around the outer side of the middle of the roller 3. A chain 9 meshes between the drive gear 7 and the driven gear 8. An annular baffle 4 is fixedly connected around both ends of the outer wall of the roller 3. A pair of annular baffles 4 are located inside the two rollers 2. During the cleaning process, the motor 6 drives the drive gear 7 to rotate. When the drive gear 7 rotates, it drives the driven gear 7 to rotate through the meshing chain 9, causing the roller 3 and the pipe to rotate accordingly, thereby achieving all-round cleaning of the inner wall of the pipe and effectively improving the cleaning effect.
[0024] Working principle: During cleaning, the height of the spray pipe 1003 is first adjusted according to the diameter of the pipe fitting. During adjustment, the lifting frame 1001 is driven to rise and fall on the side wall of the frame 1 via a lifting mechanism. As the lifting frame 1001 moves, it drives the spray pipe 1003 to move inside the roller 3 until the distance between the spray pipe 1003 and the axis of the roller 3 is less than the radius of the pipe fitting. Then, the pipe fitting is installed inside the roller 3. During installation, the end of the pipe fitting is inserted into the roller 3 along the inclined surface 1007 of the clamping plate 1005. Insertion causes the spray pipe 1003 to extend into the pipe fitting. At this time, the spring extension rods 1008 at both ends of the clamping plate 1005 shorten, generating an elastic force in the opposite direction on the clamping plate 1005, thereby clamping and fixing the pipe fitting between the clamping plates 1005. During the clamping process, the pipe fitting is fed... The wheel 1006 reduces friction between the pipe and the clamping plate 1005. The pipe is inserted into the roller 3 until its end abuts against the stop block 1009 at the other end of the clamping plate 1005, thus limiting and fixing the pipe. Then, cleaning fluid is introduced into the spray pipe 1003 through the inlet pipe 1002, so that the cleaning fluid is sprayed out along the nozzle 1004 to the inner wall of the pipe to clean the inner wall of the pipe. During cleaning, the cleaning fluid flows into the collection tank 1010 along the inclined bottom end of the pipe, realizing the recycling of the cleaning fluid. During the cleaning process, the motor 6 drives the drive gear 7 to start rotating. When the drive gear 7 rotates, it drives the driven gear 7 to rotate through the meshing wheel chain 9, so that the roller 3 and the pipe rotate accordingly, thereby realizing all-round cleaning of the inner wall of the pipe and effectively improving the cleaning effect.
