Description

Technical Field

[0001] This utility model relates to the field of strip processing technology, specifically to a strip electroplating conveying device. Background Technology

[0002] A strip electroplating conveyor is a device used in the electroplating process to transport strip materials through the electroplating tank at a stable speed, with appropriate tension and in the correct direction, thereby ensuring that the electroplating solution is applied evenly to the surface of the strip. However, while the conveyor conveys the strip through the conveyor belt, it is difficult to easily wind and flatten the strip during the strip electroplating transportation process, which limits its use.

[0003] Based on the above problems, the existing patent publication number CN222006726U discloses a strip electroplating conveyor device. By setting up a winding structure, the conveyor belt drives the rotating shaft to rotate during the rotation process, thereby winding up the roll material. Furthermore, the spacing between the fixed plate and the sliding plate is adjusted by a micro push rod, which facilitates the winding of strip materials of different sizes and prevents winding chaos. This achieves the purpose of facilitating the winding of electroplated strip materials without the need for an additional power supply.

[0004] However, when implementing the above-mentioned strip electroplating conveyor device, at least the following problems were found: Since most of the strip is made of metal, it is often coiled up for easy transportation. This means that if the strip is not tensioned enough during the electroplating process, it is easy to bend, which will affect the subsequent electroplating. Furthermore, if the coiling is too large when entering the electroplating tank, the strip is likely to come into contact with surrounding objects, causing scratches on the surface of the strip, which is not conducive to electroplating. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a strip electroplating conveying device, which solves the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides a strip electroplating conveying device, comprising: a frame, with a drum and a take-up device respectively installed inside both ends; a tensioning assembly, including an upper roller, a lower roller, a connecting plate, a movable block, a lead screw, and a servo motor, wherein the connecting plate is fixed on both sides of the frame, the movable block is slidably connected inside the connecting plate, the upper roller and the lower roller are rotatably connected to the movable block, the lead screw is threadedly connected to the movable block and rotatably connected at one end to the connecting plate, and the servo motor is fixedly installed on the top of the connecting plate and drives the lead screw to rotate; a smoothing roller, which is rotatably connected to the frame, and the strip can pass through between the two smoothing rollers; and an electroplating tank, which is fixed on the frame and located between the smoothing roller and the take-up device, with an inlet and an outlet on both sides of the electroplating tank.

[0009] Optionally, the gap between the two smoothing rollers is parallel to the feed inlet of the electroplating tank.

[0010] Optionally, two limiting rails are fixed inside the connecting plate, and the movable block is embedded in the limiting rails and slidably connected.

[0011] Optionally, an upper deflector roller is rotatably connected to the frame between the smoothing roller and the tensioning assembly.

[0012] Optionally, a lower turning roller is rotatably connected to the frame between the upper turning roller and the smoothing roller.

[0013] Optionally, nozzles are installed on both sides of the electroplating tank, and the nozzles can spray the electroplating solution in the electroplating tank onto the strip.

[0014] Optionally, a flexible scraper is provided on the inner side of the electroplating tank at the outlet.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a strip electroplating conveying device, which has the following features:

[0017] Beneficial effects:

[0018] 1. This utility model uses a servo motor to drive a lead screw to rotate, which in turn drives a movable block and an upper and lower roller connected to the movable block to move downward. At this time, the strip clamped between the upper and lower rollers is pressed and bent downward, and the strip is tensioned. Then it is transported into the electroplating tank for electroplating. This structure effectively gives the strip a certain tension. After the strip passes through the tensioning group and the smoothing roller, it can be stably transported into the electroplating tank for electroplating. This solves the problems in the prior art where the strip is easy to bend, affecting subsequent electroplating, and when entering the electroplating tank, the excessive bending amplitude makes the strip easy to come into contact with surrounding objects, causing scratches on the strip surface, which is not conducive to electroplating.

[0019] 2. This utility model uses the gap between the smoothing rollers to be parallel to the feed inlet of the electroplating tank. After the smoothing rollers flatten the strip, it can pass straight and smoothly into the electroplating tank through the feed inlet. This can ensure that the strip enters the electroplating solution in a flat state that meets the process requirements for electroplating to the greatest extent. It avoids bending, scratching and other situations that affect the electroplating quality due to changes in the direction of travel or position deviation of the strip. It helps to maintain the continuity of the entire electroplating process and the stability of the electroplating effect, and ensures the efficient and high-quality operation of the strip electroplating conveyor.

[0020] 3. This utility model, through the cooperation of the upper and lower turning rollers, can more accurately and flexibly change the travel path of the strip. The strip coming out of the tensioning group is first initially guided and turned by the upper turning roller, changing its general direction to be closer to the smoothing roller; then the lower turning roller further fine-tunes the path of the strip, ensuring that the strip can enter between the two smoothing rollers very smoothly and accurately, ensuring the smoothness of the entire strip conveying process, and minimizing the possibility of the strip getting stuck, twisted, or deviating from the normal path and getting tangled on the device components.

[0026] 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.

[0027] Example: Please refer to Figures 1 to 4 According to an embodiment of this utility model, a technical solution is provided: a strip electroplating conveying device, comprising: a frame 1, with a roller 18 and a retractor 17 respectively installed inside both ends; a tensioning assembly, comprising an upper roller 2, a lower roller 3, a connecting plate 4, a movable block 5, a lead screw 6 and a servo motor 7, the connecting plate 4 being fixed on both sides of the frame 1, the movable block 5 being slidably connected inside the connecting plate 4, the upper roller 2 and the lower roller 3 being rotatably connected to the movable block 5, the lead screw 6 being threadedly connected to the movable block 5 and rotatably connected at one end to the connecting plate 4, the servo motor 7 being fixedly installed on the top of the connecting plate 4 and driving the lead screw 6 to rotate; a smoothing roller 8, which is rotatably connected to the frame 1, and the strip can pass through between the two smoothing rollers 8; an electroplating tank 9, which is fixed on the frame 1 and located between the smoothing roller 8 and the retractor 17, with an inlet 10 and an outlet 11 on both sides of the electroplating tank 9.

[0028] In the strip electroplating conveyor with the above structure, one end of the strip wound on the drum 18 is first pulled out and passed sequentially between the upper roller 2 and the lower roller 3, between the smoothing roller 8, and through the inlet 10 and outlet 11 of the electroplating tank 9. It is then wound up by the rewinder 17. Afterwards, the servo motor 7 is started to drive the lead screw 6 to rotate, which in turn drives the movable block 5 and the upper roller 2 and lower roller 3 rotatably connected to the movable block 5 to move downwards. At this time, the strip clamped between the upper roller 2 and the lower roller 3... The strip bends downwards under pressure while being tensioned, and is then transported to the electroplating tank 9 for electroplating. This structure effectively provides the strip with a certain degree of tension. After passing through the tensioning assembly and the smoothing roller 8, the originally wound strip can be stably transported to the electroplating tank 9 for electroplating. This solves the problems in the prior art where the strip is easily bent, affecting subsequent electroplating, and when entering the electroplating tank, the excessive bending amplitude makes the strip prone to contact with surrounding objects, causing scratches on the strip surface, which is not conducive to electroplating.

[0029] The gap between the two smoothing rollers 8 is parallel to the feed inlet 10 of the electroplating tank 9. When the strip passes between the two smoothing rollers 8, since the gap between the smoothing rollers 8 is parallel to the feed inlet 10 of the electroplating tank 9, the strip can pass straight and smoothly through the feed inlet 10 into the electroplating tank 9 after being smoothed by the smoothing rollers 8. This can ensure that the strip enters the electroplating solution in a flat state that meets the process requirements for electroplating to the greatest extent, avoiding bending, scratching and other situations that affect the electroplating quality due to changes in the direction of travel or position deviation of the strip. This helps to maintain the continuity of the entire electroplating process and the stability of the electroplating effect, and ensures the efficient and high-quality operation of the strip electroplating conveyor.

[0030] Two limiting rails 12 are fixed inside the connecting plate 4. The movable block 5 is embedded in the limiting rails 12 and slidably connected. The limiting rails 12 limit the movement direction of the movable block 5, so that the movable block 5 can only slide up and down along the path specified by the limiting rails 12. This ensures that the upper roller 2 and lower roller 3 connected to the movable block 5 always maintain stable vertical movement during the tension adjustment process, without lateral deviation or other irregular shaking. This ensures that the tension adjustment of the strip by the upper roller 2 and lower roller 3 is accurate and stable, avoiding problems such as uneven tension or adjustment failure caused by the position deviation of the movable block 5.

[0031] An upper turning roller 13 is rotatably connected to the frame 1 between the smoothing roller 8 and the tensioning group. A lower turning roller 14 is rotatably connected to the frame 1 between the upper turning roller 13 and the smoothing roller 8. The upper turning roller 13 and the lower turning roller 14 work together to more accurately and flexibly change the travel path of the strip. The strip coming out of the tensioning group is first initially guided and turned by the upper turning roller 13, changing its general direction to be closer to the smoothing roller 8. Then the lower turning roller 14 further fine-tunes the route of the strip, ensuring that the strip can enter between the two smoothing rollers 8 very smoothly and accurately. This ensures the smoothness of the entire strip conveying process and minimizes the possibility of the strip getting stuck, twisted, or deviating from the normal path and getting tangled on the device components. This allows the strip to flow orderly between the various functional components, laying the foundation for the smooth progress of the subsequent electroplating process.

[0032] Spray nozzles 15 are installed on both sides of the electroplating tank 9. The spray nozzles 15 can spray the electroplating solution in the electroplating tank 9 onto the strip. The electroplating process depends on the full and uniform contact between the electroplating solution and the surface of the strip. Under normal circumstances, the strip is only immersed in the electroplating tank 9, and there may be some areas that do not have sufficient contact with the electroplating solution. The spray nozzles 15 can spray the electroplating solution in the electroplating tank 9 onto the strip, so that the electroplating solution impacts the surface of the strip with a certain pressure and angle. This can ensure that all parts of the strip, especially some corners and gaps where the electroplating solution is prone to insufficient coverage, can be fully coated by the electroplating solution, thereby promoting a more uniform and efficient electroplating reaction, which helps to improve the quality of the electroplated layer, making its thickness more uniform and its adhesion stronger, and thus improving the overall performance and appearance quality of the strip after electroplating.

[0033] A flexible scraper 16 is provided on the inner side of the electroplating tank 9 at the outlet 11. When the strip leaves the electroplating tank 9 after electroplating, a large amount of electroplating solution will be attached to its surface. If this electroplating solution is carried directly out of the electroplating tank 9, it will not only waste the electroplating solution, but may also pollute the surrounding environment. The flexible scraper 16 can gently scrape off the excess electroplating solution on the surface of the strip, so that the electroplating solution can flow back into the electroplating tank 9 for recycling. This achieves effective resource recovery, reduces the cost of the electroplating production process, and also meets the requirements of environmental protection and resource conservation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
