Description

Technical Field

[0001] This invention relates to the technical field of pickling and drying equipment for tin-plated copper wire, specifically to a continuous integrated pickling and drying equipment for tin-plated copper wire. Background Technology

[0002] Tinned copper wire combines the excellent conductivity of copper with the corrosion resistance and solderability of tin, and is widely used in industries such as wire and cable, electronics and electrical appliances and new energy.

[0003] The pickling and drying equipment for tin-plated copper wire is a key pretreatment equipment in the production process of tin-plated copper wire. Its core function is to perform efficient pickling and drying treatment on the copper wire before tin plating, thereby removing impurities such as oxide film, oil stains, and copper mud from the surface of the copper wire, while removing residual acid and moisture after pickling, so as to provide a clean and dry copper wire surface for the subsequent tin plating process.

[0004] However, the existing pickling tanks for tin-plated copper wire still lack efficiency and stability in multi-stage filtration and cleaning of the acid solution, which reduces the efficiency of subsequent acid recycling. At the same time, the existing tin-plated copper wire pickling equipment also lacks integration in drying the copper wire after pickling. Therefore, there is an urgent need for a continuous tin-plated copper wire pickling and drying integrated equipment to solve the above problems. Summary of the Invention

[0036] Two sets of drain pipes 1 are fixedly installed at the bottom of the cleaning tank 4, and the filtrate assembly 2 is connected to the cleaning tank 4 through the drain pipes 1.

[0037] The power output end of the servo motor 8 is provided with a transmission turntable 9, and a guide pin 6 is provided on the lower end face of the transmission turntable 9.

[0038] like Figure 3 and Figure 4 The filtrate assembly 2 includes a support base 24, two sets of meshing filter components 22 are rotatably engaged on the inner end face of the support base 24, a stepper motor 21 is provided on the side of the upper end face of the support base 24, and a drive gear 23 is provided at the power output end of the stepper motor 21. An alignment guide tube 25 is fixedly provided at the center of the lower end face of the support base 24.

[0039] like Figure 5 The filter assembly 22 includes a liquid guide cylinder 221. A driven gear 222 is fixedly installed on the outside of the liquid guide cylinder 221. Four sets of positioning grooves 223 are equally spaced on the inner end face of the liquid guide cylinder 221. Three sets of filter plates 225 are equally spaced on the inner end face of the liquid guide cylinder 221. Four sets of limiting sliders 226 are provided on the side of each set of filter plates 225. A threaded cap 224 is threadedly connected to the top of the liquid guide cylinder 221.

[0040] like Figure 6 The screening component 3 includes a screening box 34. A guide slide plate 33 is fixedly installed at the center of the upper end face of the screening box 34, and three sets of filter screens 32 are equidistantly slidably engaged on the inner end face of the screening box 34. Three sets of positioning guide grooves 31 are equidistantly opened on the side end face of the screening box 34.

[0041] like Figure 7 and Figure 8 The pickling and drying assembly 7 includes a pickling chamber 72 for support, a sealing cover 73 fixedly installed on the top of the pickling chamber 72, a liquid pump 74 fixedly installed on the top of the sealing cover 73, and a liquid pipe 711 fixedly installed at the bottom of the pickling chamber 72. The inner end face of the pickling chamber 72 is provided with a first guide roller 71 at equal intervals, and a drying chamber 710 for drying is fixedly installed at the front of the pickling chamber 72. The inner end face of the drying chamber 710 is provided with a second guide roller 79 at equal intervals and rotatably engaged. A fixed cover 76 is fixedly installed at the top of the drying chamber 710 and an air inlet pipe 75 is fixedly installed at the center of the upper end face of the fixed cover 76. Four sets of drying fans 77 are fixedly installed at equal intervals on the inner walls of the drying chamber 710 and the fixed cover 76. A cleaning sleeve 78 is provided at the material guide opening of the pickling chamber 72 and the drying chamber 710.

[0042] like Figure 6 The filter screen 32 is slidably engaged inside the screening box 34 via the positioning guide groove 31. The pickling box 72 is connected to the inlet pipe 10 through the liquid guide pipe 711, and the side of the liquid guide pump 74 is connected to 25 through the liquid replacement pipe. This makes it convenient for the filter screen 32 to be removed from the screening box 34 through the positioning guide groove 31 after long-term use, thus improving the ease of use.

[0043] like Figure 2 The transmission turntable 9 is adapted to the guide plate 33 through the guide pin 6, thereby driving the screening box 34 to move back and forth inside the cleaning tank 4. The upper part of the threaded cover 224 is sealed and rotated with the drain pipe 1. During screening, the guide pin 6 can move back and forth inside the cleaning tank 4 through the sliding limit with the guide plate 33, thereby improving the efficiency of removing various impurities inside the acid solution.

[0044] like Figure 5 The driving gear 23 meshes with the driven gear 222, and the filter plate 225 slides and engages with the positioning groove 223 via the limiting slider 226. After long-term use, the threaded cover 224 can be separated from the upper part of the liquid guide cylinder 221 by means of threads, and the filter plate 225 can be disassembled and replaced via the positioning groove 223, which improves the convenience of subsequent use.

[0045] Working principle: Before use, the operator can connect one end of the liquid replacement pipeline to the liquid transfer pump 74 and the other end of the liquid replacement pipeline to the alignment guide tube 25 to facilitate the circulation of acid solution for subsequent pickling.

[0046] During pickling and drying, the workers can sequentially pass the tin-plated copper wires to be pickled and dried through the pickling tank 72 and the drying tank 710. Multiple sets of guide rollers 71 located inside the pickling tank 72 and the drying tank 710 can transport and guide the tin-plated copper wires. The guide rollers 71 are located at the bottom of the pickling tank 72, which allows the introduced tin-plated copper wires to be immersed in the bottom of the pickling tank 72, improving the reaction stability with the acid solution. At the same time, the pickled tin-plated copper wires are initially cleaned by the cleaning sleeve 78 and then enter the drying tank 710. The guide rollers 79 are located in the middle of the drying tank 710, which allows the dried part of the tin-plated copper wires to pass through the middle of the drying tank 710, thereby improving the drying efficiency of the upper and lower sets of drying fans 77. After drying, the tin-plated copper wires are cleaned again by the outermost cleaning sleeve 78 and then exported.

[0047] If cleaning of the acid solution after pickling tin-plated copper wire is required, the operator can start the liquid pump 74 via the external touch screen module. The liquid pump 74 facilitates the extraction of the cleaned acid solution from the bottom of the alignment guide tube 25 and then introduces it into the pickling tank 72. At the same time, the turbid liquid at the bottom of the pickling tank 72 can be introduced into the cleaning tank 4, completing the liquid circulation. Then, the servo motor 8 and stepper motor 21 can be started via the PLC in the external touch screen module. At this time, the servo motor 8 can drive the transmission turntable 9 to rotate, so that the transmission turntable 9 can be guided by the guide shaft 6 and the guide. The sliding limit of the slide plate 33 drives the screening box 34 and multiple sets of filter screens 32 to move back and forth, thereby performing all-round reciprocating screening of the acid solution introduced by the inlet pipe 10, and initially filtering the impurities inside. Then, the screened acid solution is introduced into the liquid guide cylinder 221 through the drain pipe 1. At this time, the stepper motor 21 can drive the two sets of liquid guide cylinders 221 to rotate synchronously through the drive gear 23 and two sets of driven gears 222, so that the liquid guide cylinder 221 can perform multi-stage filtration of the acid solution through multiple sets of filter plates 225 inside, improving the cleanliness of the acid solution in the subsequent return.
