Description

Technical Field

[0001] This utility model relates to the field of plating solution filling technology, and in particular to a hot-dip galvanizing low-temperature plating solution filling device. Background Technology

[0002] In metal processing plants, it is used to precisely fill low-temperature plating solution into electroplating tanks, suitable for hot-dip galvanizing of small or large parts such as bolts and steel pipes; in automotive parts production, it is used to quantitatively fill plating solution for the galvanizing process of vehicle frames and chassis parts to ensure uniform coating; in steel structure workshops, it is used to automatically fill plating solution for steel profiles and connectors.

[0003] A search revealed Chinese Patent Publication No. CN216916387U, which discloses a low-temperature hot-dip galvanizing solution filling device for metal surfaces. The device includes a U-shaped plate with a conveying device below it. The U-shaped plate is fixedly connected to both sides of the conveying device. A hydraulic cylinder is vertically mounted on the top of the U-shaped plate, and a strip plate is mounted on the bottom of the hydraulic cylinder, perpendicular to the cylinder. Multiple equidistant support discs are arranged along the length of the strip plate below it. The tops of the support discs are fixedly connected to the strip plate via support rods. A filling conduit is coaxially mounted on the bottom of the support discs. A liquid level sensor is installed at the lower end of one side of the filling conduit, and a sleeve is provided on the outer side of the bottom of the filling conduit. In use, the multiple guide rods slide within the cylindrical cavity, allowing the filling conduit to extend vertically into the carrier. Upon contact with the pressure sensor, filling begins. The liquid level sensor quantitatively monitors the entire filling process, ensuring that the plating solution does not overflow the carrier during filling.

[0004] The patent description mentions that "by sliding multiple guide rods within the cylindrical cavity, the filling conduit extends vertically into the carrier. Upon contact with the pressure sensor, filling begins. In conjunction with the liquid level sensor, the entire filling process is quantitatively monitored to ensure that the plating solution does not overflow from the carrier during filling." However, it cannot achieve precise positioning, resulting in poor alignment between the filling port and the container, which easily leads to plating solution overflow and waste, polluting the workshop environment. Furthermore, it has low adaptability to different specifications of filling containers, requiring repeated adjustments when changing containers. To address the above-mentioned problems, a low-temperature hot-dip galvanizing solution filling device is proposed. Utility Model Content

[0005] This utility model proposes a hot-dip galvanizing low-temperature plating solution filling device, which aims to improve the problem that some existing hot-dip galvanizing low-temperature plating solution filling devices cannot achieve precise positioning.

[0006] The hot-dip galvanizing low-temperature plating solution filling equipment provided in this application adopts the following technical solution: A hot-dip galvanizing low-temperature plating solution filling device includes a workbench, a plurality of fixed plates fixedly connected to the top of the workbench, a control panel fixedly connected to the outside of the workbench, a connecting block fixedly connected to the outside of the workbench, a positioning mechanism fixedly connected to the outside of the connecting block, and an anti-deviation mechanism fixedly connected to the outside of the fixed plates. The positioning mechanism includes a guide rail, which is disposed outside the connecting block. A slider is slidably connected to the outside of the guide rail. A connecting plate is fixedly connected to the outside of the slider. A groove is fixedly connected to the outside of the connecting plate. A sliding block is slidably connected to the outside of the groove. A strip plate is slidably connected to the outside of the groove. Multiple discs are fixedly connected to the bottom of the strip plate. An infusion conduit is fixedly connected to the bottom of the disc. A liquid level sensor is fixedly connected to the outside of the infusion conduit. A transmission assembly is fixedly connected to the outside of the disc.

[0007] The above solution utilizes the sliding cooperation of guide rails, sliders, and chutes to drive the connecting plate and strip plate to move in multiple directions, enabling flexible alignment of the filling conduit. The liquid level sensor monitors the plating solution level in real time, and the transmission components assist in precise adjustment, improving the adaptability of the filling position and the accuracy of the dosage, thus ensuring stable and efficient operation of the equipment.

[0008] Preferably, the anti-deviation mechanism includes a support frame, which is externally fixedly connected to the outside of the fixed plate. Multiple fixing blocks are fixedly connected to the left and right sides of the outside of the support frame. Connecting bolts are threaded onto the outside of the fixing blocks, and an adjustment knob is fixedly connected to the left side of the connecting bolts.

[0009] The above solution provides stable support for the entire system by fixing the support frame to the fixed plate. The left and right side fixing blocks are connected with bolts, and the bolt positions can be flexibly adjusted by adjusting the knobs. This allows for precise adjustment according to the container size, enhances the limiting ability of the filling container, and reduces deviation.

[0010] Preferably, the transmission assembly includes a sleeve, a pressure sensor is fixedly connected inside the sleeve, a guide rod is slidably connected inside the sleeve, and the top of the guide rod is fixedly connected to the outside of the disc.

[0011] The above solution provides installation space for the pressure sensor and guide rod. The guide rod is slidably connected to the sleeve and connected to the disc, and can move flexibly as the disc position changes. The pressure sensor can monitor pressure changes in real time and provide feedback on the force status during the filling process, ensuring accurate adjustment and stable equipment operation.

[0012] Preferably, a support plate is fixedly connected to the outside of the sliding block, a hydraulic cylinder is fixedly connected to the outside of the support plate, and an infusion pipe is fixedly connected to the outside of the strip plate.

[0013] The above solution involves a sliding block that fixes the hydraulic cylinder to a support plate, providing stable support for the hydraulic cylinder. The hydraulic cylinder can drive the strip plate to precisely adjust its position to adapt to different filling requirements. The liquid delivery pipe connected to the strip plate can stably deliver the plating solution. Combined with position adjustment, this achieves efficient filling and ensures continuous plating solution delivery and operational flexibility.

[0014] Preferably, the external thread of the connecting bolt is connected to a follower rod, the top of the follower rod is fixedly connected to a U-shaped plate, and the external part of the follower rod is slidably connected to the inside of the fixed block.

[0015] The above solution involves connecting bolts and follower rods with threads. Rotating the bolts drives the follower rods to move. The follower rods slide within the fixed block to ensure smooth movement. The U-shaped plate at the top of the follower rods transmits power, enabling precise adjustment of the positions of subsequent components. This adapts to different container sizes and enhances the adjustment flexibility and stability of the anti-deviation mechanism.

[0016] Preferably, the U-shaped plate is externally fixedly connected to a support rod, the support rod is externally fixedly connected to a positioning plate, and the support frame is externally fixedly connected to a conveying assembly.

[0017] The above solution involves connecting the positioning plate with a support rod, which allows the adjustment force to be transmitted to the positioning plate, enabling precise clamping and positioning of the container. The conveying components on the support frame can stably transport the container, working in conjunction with the positioning plate to ensure that the container is fixed in position during filling, reducing offset and improving the stability and efficiency of the filling operation.

[0018] Preferably, the conveying assembly includes a conveying roller, the outside of which is fixed to the outside of the support frame, and a conveyor belt is provided on the outside of the conveying roller.

[0019] The above solution involves fixing the conveyor rollers of the conveying assembly to the support frame, providing stable support and driving force for the conveyor belt. The conveyor belt operates by relying on the conveyor rollers, which can smoothly transport the containers to be filled, ensuring that the containers move to the filling position in an orderly manner. In conjunction with the positioning mechanism, it reduces conveying deviation and ensures that the filling operation is carried out continuously and efficiently.

[0020] Preferably, the slider is fixedly connected to the outside of the connecting plate, and the connecting plate is slidably connected to the outside of the connecting block.

[0021] The above solution involves a slider that is fixedly connected to a connecting plate, which can drive the connecting plate to move synchronously. The connecting plate is slidably connected to a connecting block, and the connecting block provides support for smooth sliding. This ensures that the positioning mechanism adjusts its position along a predetermined trajectory, enhances the stability and accuracy of component movement, and provides a reliable basis for filling position adjustment.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, the connecting plate is driven by the slider, which in turn drives the strip plate to move. This causes the sleeve to slide outside the chute, thereby accurately calibrating the relative position of the filling head and the container. This allows for the adaptation to various container sizes, offsetting positioning errors of the conveyor belt or container, reducing leakage and splashing, facilitating quick switching of filling parameters, enhancing the equipment's adaptability to minor changes in the production environment, and ensuring filling consistency and stability.

[0023] 2. In this utility model, a fixing block is installed on the outside of the support frame. When it is necessary to adjust the spacing of the positioning plates, the adjustment knob is turned so that the connecting bolt drives the follower rod to move, which in turn causes the U-shaped plate to drive the support rod to move. This allows for flexible adaptation to workpieces of different specifications, improves the versatility of the equipment, and ensures that the workpiece is centered by precise fine-tuning of the spacing, reduces conveying deviation, adapts to the plating solution environment, and ensures filling accuracy and production continuity.

[0026] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be further described in detail. Example: A hot-dip galvanizing low-temperature plating solution filling device, referring to... Figure 1 , Figure 2 and Figure 4 A hot-dip galvanizing low-temperature plating solution filling device includes a workbench 1. Multiple fixed plates 2 are fixedly connected to the top of the workbench 1. The fixed plates 2 are rectangular plate-like structures, vertically erected on the top of the workbench 1, and evenly distributed along the length of the workbench 1. A control panel 3 is fixedly connected to the outside of the workbench 1. Connecting blocks 4 are rectangular block-like structures, fixed to the edge of the top of the workbench 1. A groove adapted to a guide rail 51 is formed on one side of the block. The inner wall of the groove is smooth, providing stable support for the installation of the guide rail 51. The connecting block 4 is externally fixedly connected to a positioning mechanism 5, and the fixing plate 2 is externally fixedly connected to an anti-offset mechanism 8. The positioning mechanism 5 includes a guide rail 51, which is externally located outside the connecting block 4. A slider 52 is slidably connected to the outside of the guide rail 51. The top plane of the slider 52 is tightly fitted with the bottom of the connecting plate 53. When sliding, it can drive the connecting plate 53 to move synchronously. The slider 52 is externally fixedly connected to a connecting plate 53, and the connecting plate 53 is externally fixedly connected to a sliding groove 54. The sliding groove 54 is a long strip-shaped groove structure arranged along the width direction of the connecting plate 53. A sliding block 55 is slidably connected to the outside of the slide groove 54. The sliding block 55 has a block-shaped structure and a groove at the bottom that matches the slide groove 54. A wear-resistant pad is installed in the groove to reduce wear during sliding. The sliding block 55 can move freely along the slide groove 54, and the direction of movement is perpendicular to the sliding direction of the slider 52, thereby driving the support plate 56 to adjust its position. A strip plate 58 is slidably connected to the outside of the slide groove 54. When the hydraulic cylinder 57 is working, the piston rod will extend or retract, pushing the strip plate 58 to slide, thereby adjusting the position of the strip plate 58. The bottom of the strip plate 58 is fixedly connected to multiple discs 59. The diameter of the discs 59 is slightly larger than the diameter of the pouring conduit 510, which can provide stable support for the pouring conduit 510. The center of the disc 59 has a through hole that is connected to the pouring conduit 510. The bottom of the disc 59 is fixedly connected to the pouring conduit 510. The inner wall of the pouring conduit 510 is smooth, which can reduce the resistance when the plating solution flows. The end of the conduit is cut at an angle, so that the plating solution can flow smoothly into the container. The outside of the pouring conduit 510 is fixedly connected to a liquid level sensor 511. The liquid level sensor 511 is a small cylindrical structure, installed near the end of the filling conduit 510. The probe of the liquid level sensor 511 extends into the conduit and can detect the liquid level of the plating solution in the conduit in real time and transmit the signal to the control panel 3. The transmission assembly 6 is fixedly connected to the outside of the disc 59. The transmission assembly 6 includes a sleeve 61. The pressure sensor 62 is fixedly connected inside the sleeve 61. The guide rod 63 is slidably connected inside the sleeve 61. The top of the guide rod 63 is fixedly connected to the outside of the disc 59. The support plate 56 is fixedly connected to the outside of the sliding block 55. The hydraulic cylinder 57 is fixedly connected to the outside of the support plate 56. The infusion tube 7 is fixedly connected to the outside of the strip plate 58. The infusion tube 7 has a certain elasticity and can bend with the movement of the strip plate 58 without affecting the delivery of the plating solution. The slider 52 is fixedly connected to the outside of the connecting plate 53. The connecting plate 53 is slidably connected to the outside of the connecting block 4. Specifically, after starting via the control panel 3, the slider 52 of the positioning mechanism 5 slides along the guide rail 51, driving the connecting plate 53 and the slide groove 54 to move. The sliding block 55 slides along the slide groove 54, and the strip plate 58 slides along the slide groove 54 under the action of the hydraulic cylinder 57, adjusting the position of the disc 59 and the bottom filling conduit 510. The liquid delivery pipe 7 delivers the plating solution to the disc 59, which is then filled through the filling conduit 510. The liquid level sensor 511 detects the liquid level of the plating solution in the conduit. The guide rod 63 of the transmission component 6 slides in the sleeve 61, the pressure sensor 62 operates, and the anti-deviation mechanism 8 works in conjunction with the fixing plate 2.

[0027] Reference Figure 1 , Figure 3 and Figure 5 The anti-deviation mechanism 8 includes a support frame 81, which is externally fixed to the outside of the fixing plate 2. Multiple fixing blocks 82 are fixedly connected to the left and right sides of the support frame 81. The fixing blocks 82 are rectangular block structures, evenly distributed along both sides of the support frame 81. Threaded holes and smooth through holes are provided inside the blocks. The threaded holes are adapted to the connecting bolts 83, and the smooth through holes allow the follower rod 85 to pass through. The sides of the fixing blocks 82 are tightly fitted to the rod body of the support frame 81 to ensure stable installation. The external threads of the fixing blocks 82... The connection is made of a connecting bolt 83, which is a cylindrical rod structure with uniform threads engraved on its surface. One end passes through the threaded hole of the fixing block 82 and is connected to the follower rod 85, and the other end is fixed to the adjusting knob 84. The threads of the bolt match the threads of the fixing block 82 and the follower rod 85. When rotated, it can drive the follower rod 85 to move. The adjusting knob 84 is fixedly connected to the outer left side of the connecting bolt 83. The follower rod 85 is connected to the outer thread of the connecting bolt 83. The top of the follower rod 85 is fixedly connected to a U-shaped plate 86. The follower rod 85 is externally slidably connected to the inside of the fixed block 82. The U-shaped plate 86 is externally fixedly connected to a support rod 87. The support rod 87 is a cylindrical rod structure, vertically fixed to the side of the U-shaped plate 86, and extends towards the center of the support frame 81. The length of the rod can be adjusted according to the size of the filling container. The extended end is connected to the positioning plate 88 and can swing synchronously with the movement of the U-shaped plate 86. The support rod 87 is externally fixedly connected to a positioning plate 88. The positioning plate 88 is a rectangular plate structure, vertically fixed to the extended end of the support rod 87. The plate surface is smooth, and a wear-resistant rubber pad is pasted on the side facing the filling container. It can move closer to or away from the container as the support rod 87 moves, thereby clamping the container and preventing the container from shifting during the filling process. The support frame 81 is externally fixedly connected to a conveying assembly 89. The conveying assembly 89 includes a conveying roller 891. The conveying roller 891 is externally fixed to the outside of the support frame 81, and a conveyor belt 892 is provided on the outside of the conveying roller 891. Specifically, operating the adjustment knob 84 causes the connecting bolt 83 to rotate. Since the connecting bolt 83 is threadedly connected to the follower rod 85, the follower rod 85 slides inside the fixed block 82. When the follower rod 85 moves, the top U-shaped plate 86 moves synchronously, thereby causing the support rod 87 and the positioning plate 88 to change position. After the conveying assembly 89 is started, the conveying roller 891 starts to rotate, and the conveyor belt 892 moves under the drive of the conveying roller 891, conveying the container to be filled to the designated position. The positioning plate 88 continuously adjusts its position with the support rod 87 to adapt to containers of different sizes, ensuring that the container remains stable during the conveying and filling process.

[0028] The implementation principle of this application embodiment is as follows: the slider 52 slides along the guide rail 51, which drives the connecting plate 53 and the slide groove 54 to move, so that the sliding block 55 slides along the slide groove 54, adjusts the position of the support plate 56 and the hydraulic cylinder 57, and the piston rod of the hydraulic cylinder 57 extends and retracts, pushing the strip plate 58 to slide along the slide groove 54, and then the disc 59 and the filling conduit 510 move with the strip plate 58, aligning with the container opening, the infusion tube 7 delivers the plating solution to the sleeve 61, the guide rod 63 slides in the sleeve 61, the pressure sensor 62 detects the plating solution pressure, and the plating solution flows into the filling conduit 510 through the disc 59 and is injected into the container; By placing the filling container on the conveyor belt 892, the conveyor roller 891 rotates, driving the conveyor belt 892 to move. The container is conveyed downwards to the filling conduit 510 along the conveyor belt 892. Rotating the adjustment knob 84 causes the connecting bolt 83 to rotate, and the follower rod 85 slides along the through hole of the fixed block 82, causing the U-shaped plate 86 and the support rod 87 to move synchronously. The positioning plate 88 moves closer to the container and clamps the container. After filling is completed, the positioning plate 88 moves away from the container, the conveyor belt 892 conveys the container out, and all components are reset, ready for the next filling.

[0029] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
