Description

Technical Field

[0001] The invention relates to the technical field of bronze strip passivation treatment, in particular to a surface passivation treatment device for a tin-phosphor bronze strip. Background Art

[0002] As an important metal material, tin-phosphor bronze is widely used in electrical, mechanical, chemical and other fields. In order to ensure that tin-phosphor bronze strips are not easily oxidized and corroded in humid or corrosive environments, tin bronze needs to be surface passivated to improve its corrosion resistance and stability. Surface passivation forms a dense oxide film on the metal surface to prevent direct contact between the metal and the external environment, thereby achieving the purpose of improving corrosion resistance and improving its surface gloss and mechanical properties, thereby improving the overall use effect.

[0003] In the prior art, the tin-phosphorus bronze strip is transferred in a passivation tank filled with passivation liquid through the cooperation of unwinding and rewinding equipment. After continuous immersion in the passivation liquid, a dense oxide film is formed on the surface of the tin-phosphorus bronze strip for protection. In the process of removing the tin-phosphorus bronze strip from the passivation tank, a part of the passivation liquid will be taken away, which will not only lead to waste of the passivation liquid, but also make the passivation liquid drip into the external working environment, thereby polluting the external working environment. With the continuous improvement of technology, there are also matching structures on the market for scraping off the passivation liquid attached to the surface of the tin-phosphorus bronze strip, but most of them only have basic scraping ability, so that the water droplets on the surface can be taken away, but there is no good solution for the water film generated by the sliding of the water droplets, and the actual drying ability is limited. In this regard, the present invention provides a surface passivation treatment device for tin-phosphorus bronze strip to solve the above problems. Summary of the invention

[0048] The extrusion assembly includes a guide rod 416 fixed to the front and back sides of the rectangular plate 414 respectively, four guide arc plates 417 are fixed to the front and rear inner walls of the support frame 401, and two corresponding guide arc plates 417 on the same side form a guide channel capable of guiding and restricting the guide rod 416, two vertical plates 424 are fixed between the front and rear inner walls of the support frame 401, and a trapezoidal frame 425 with openings on both the front and rear sides is fixed between the opposite sides of the two vertical plates 424, a water collecting box 428 is fixed to the opposite sides of the two vertical plates 424, and a guide pipe 429 connected to the inside of the water collecting box 428 is fixed to the bottom; a plurality of drain holes 426 are opened on the opposite sides of the two trapezoidal frames 425, and the openings of the drain holes 426 are arc-shaped, a drain port 427 is opened at the bottom of the trapezoidal frame 425, and the inner bottom wall of the water collecting box 428 is inclined toward the side close to the corresponding guide pipe 429;

[0049] The control component includes two limiting rods 440 fixed to the right side of the extrusion plate 439 and the right ends of which pass through the left side of the adjustment plate 431. The right side of the adjustment plate 431 is rotatably connected to an internal threaded tube 441 through a bearing. Two handle rods 442 are fixedly installed on the outer side of the internal threaded tube 441. A threaded rod 443 is fixed to the right side of the extrusion plate 439.

[0050] like Figure 8 As shown, it should be noted that the inner side of the passivation box 202 is rotatably connected to the third guide roller 321 located below the support frame 401 through a bearing, so that the bronze belt can be conveyed to the side close to the support frame 401 through the guiding effect of the third guide roller 321, and the left and right sides of the internal threaded cylinder 441 are both open, and the right end of the threaded rod 443 passes through the left side of the adjustment plate 431 and extends to the right side of the adjustment plate 431, and the outer side of the threaded rod 443 and the inner side of the internal threaded cylinder 441 are threadedly connected, and the internal threaded cylinder 441 is rotated by two handle bars 442. Under the limiting effect of the two limiting bars 440, the extrusion plate 439 can not be driven to rotate, so that the internal threaded cylinder 441 can rotate while pushing the threaded rod 443 to move through the inner thread, and compressing the second spring 437 to adjust the pressure on the movable drying plate 433.

[0051] like Figure 7 As shown, in addition, the side of the trapezoidal frame 425 away from the corresponding vertical plate 424 is an inclined surface and can be used for squeezing the corresponding sponge pad 415. The guide channel can limit the internal guide rod 416, and then when the sponge pad 415 is squeezed by the trapezoidal frame 425, the compression degree of the first spring 412 can be limited, so that the sponge pad 415 can be fully squeezed so that the internal liquid can be discharged. The drain port 427 is located above the water collecting tank 428, so that the water discharged from the drain port 427 can be received by the water collecting tank 428.

[0052] At the same time, the front and back sides of the torsion spring 403 are respectively fixedly connected to the inner front side wall of the support frame 401 and the front side of the corresponding connecting block 404, so that when the connecting block 404 rotates, it can drive the corresponding torsion spring 403 to undergo elastic deformation, and then the triangular scraper 405 can continue to fit the surface of the bronze belt. The four limit blocks 406 are respectively located on the left and right sides of the two connecting blocks 404, which are used to limit the maximum left and right rotation angles of the connecting blocks 404. The first telescopic rod 413 and the second telescopic rod 438 are both composed of a sleeve and an inner rod slidably connected to the inner side of the sleeve, and the end of the inner rod passes through the outer side of the sleeve and extends to the outside world. A limit plate with a diameter larger than the diameter of the inner rod is fixed to one end of the inner rod located inside the corresponding sleeve, which can enable the first telescopic rod 413 and the second telescopic rod 438 to have the ability to telescopically and slidably cooperate, so as to cooperate with the first spring 412 and the second spring 437 to work.

[0053] Among them, the two first hot air pipes 419 both penetrate the back side of the support frame 401 and one end of the back side of the corresponding air guide pipe 407 and extend into the interior thereof. The outer side of the first hot air pipe 419 and the inner side of the corresponding air guide pipe 407 are rotatably connected, so that the hot air inside the first hot air pipe 419 can be transported to the interior of the air guide pipe 407, that is, it can be discharged through the air delivery hole 409 and the air blowing pipe 410 to blow and dry the bronze belt. The two arc-shaped air guide plates 421 can guide the hot air blown out of the air blowing pipe 410 away from the side of the bronze belt upward and downward, and then can make certain use of it to assist in blowing the upper and lower parts of the bronze belts.

[0054] like Fig. 9 As shown, it should also be noted that the right side of the correction roller 422, the right side of the wavy scraper 434 on the positioning drying plate 430, and the left side of the matching roller 423 are all located in the same longitudinal plane, so that the bronze belt transmitted through the right side of the correction roller 422 and the left side of the matching roller 423 can be corrected to be parallel and fit to the right side of the wavy scraper 434 on the positioning drying plate 430, so that the right side wavy scraper 434 can be stably flatly fitted, so that the scraping and drying effects can be improved.

[0055] In addition, the wavy scraper strip 434 is composed of two V-shaped scraper strips, and a circular hole is opened at the bottom of the V-shaped scraper strip. The outer corners of the wavy scraper strip 434 are arc-shaped, so that the wavy scraper strip 434 can fit and scrape the surface of the bronze belt. Under the restriction of the double V-shaped structure, the scraped liquid can flow toward the sharp end of the bottom instead of flowing to the sides. The liquid accumulated on the top of the wavy scraper strip 434 can be discharged normally through the circular hole, thereby improving the scraping and drying effect.

[0056] It should be understood that one end of the back side of the bronchial hose 435 passes through the back side of the support frame 401 and is fixedly connected to the outer side of the corresponding second hot air duct 420, and the fixed tubes 436 on the left and right sides, away from one end of the corresponding bronchial hose 435, respectively pass through the opposite side of the positioning drying plate 430 and the movable drying plate 433, and extend to the opposite side of the positioning drying plate 430 and the movable drying plate 433, respectively, so that the hot air transported from the inside of the second hot air duct 420 can enter the inside of the bronchial hose 435 and then be discharged through the fixed tube 436 to dry the surface of the bronze belt.

[0057] The working principle of the above embodiment is:

[0058] (1) When the tin-phosphor bronze strip is passivated, the tin-phosphor bronze strip is allowed to enter the interior of the cleaning box 201, and is sequentially passed through the top of the outer side of the first first guide roller 308 on the left, the bottom of the outer side of the hollow guide roller 318 in the cleaning box 201, the top of the outer side of the first first guide roller 308 on the right, and the top of the second guide roller 320, and is then transported to the interior of the passivation box 202, and then sequentially passes through the outer sides of the three hollow guide rollers 318 in the passivation box 202, and under the guidance of the third guide roller 321, sequentially passes between the opposite sides of the two triangular scrapers 405 and between the opposite sides of the two support rollers 408, and under the action of the correction roller 422 and the matching roller 423, the inclined tin-phosphor bronze strip can be corrected to a vertical state, so that it can be moved in a vertical state to between the opposite sides of the positioning drying plate 430 and the movable drying plate 433, and finally is reeled by the reeling mechanism 203.

[0059] (2) After the tin-phosphor bronze strip enters the cleaning box 201 through the above process, the air delivery fan 301 is started so that the filtered air can be delivered through the second main pipe 313 and the first main pipe 302, wherein the air inside the second main pipe 313 is delivered to the inside of the second branch pipe 314 and each third branch pipe 315. Under the action of the connecting hole 316, the air inside the second branch pipe 314 and the third branch pipe 315 can be discharged, and then discharged to the inside of the cleaning box 201 and the passivation box 202 through the through hole on the outer surface of the hollow guide roller 318, so as to improve the activity and fluidity of the liquid, so that the tin-phosphor bronze strip can be more fully In order to achieve the cleaning and passivation effect, starting the ultrasonic cleaner 306 can release ultrasonic waves to the inside of the cleaning box 201, thereby causing the liquid to vibrate, so that the cleaning effect is further improved. Moreover, under the cleaning action of the two cleaning pads 312, the conveyed tin-phosphor bronze belt can be wiped to remove the stains attached to its surface. The air entering the first main pipe 302 enters the inside of the two exhaust pipes 304 respectively through the two first branch pipes 303, and is finally discharged through the nozzle 305. The air sprayed from the nozzle 305 can blow away the water droplets on the surface of the tin-phosphor bronze belt to prevent it from dripping into the outside during the conveying process.

[0060] (3) The tin-phosphor bronze strip entering the passivation box 202 can be stably transported inside the passivation box 202 through the support and guidance of the corresponding hollow guide roller 318 and the air output by the third branch pipe 315, while improving a certain passivation efficiency, so that it can be fully passivated. The passivated tin-phosphor bronze strip is transported upward under the action of the second guide roller 320. Under the elastic support of the torsion spring 403, the triangular scraper 405 can be tightly attached to the surface of the tin-phosphor bronze strip to scrape water, so that large particles of passivation liquid droplets can be scraped off. The tin-phosphor bronze strip continues to be driven by the winding mechanism 203 for transportation, and the sponge pads 415 on both sides are driven by the friction force to move forward. The first spring 412 and the first telescopic rod 413 cooperate to make the rectangular plate 414 have a certain activity space, so that the sponge pad 415 can continuously fit with the surface of the tin-phosphor bronze belt, and the rectangular plate 414 that is rotated to the side away from the tin-phosphor bronze belt can be limited under the cooperation of the guide arc plate 417 and the guide rod 416, so that the first spring 412 will not be over-compressed, and the sponge pad 415 can be fully squeezed by the trapezoidal frame 425 on the same side, so that the liquid inside can be discharged, and flow into the water collecting box 428 through the drain hole 426 and the drain port 427, and finally discharged back to the passivation box 2 through the guide pipe 429. 02, start the hot air blower 418, so that the hot air enters the first hot air pipe 419 and the second hot air pipe 420 respectively, the hot air in the first hot air pipe 419 is transported to the inside of the corresponding air guide pipe 407, and is discharged through the air delivery hole 409 and the air blowing pipe 410, and the tin-phosphor bronze belt moving through the sponge pad 415 is preliminarily dried, and the hot air in the air blowing pipe 410 that rotates to the side away from the tin-phosphor bronze belt is transported upward or downward under the guidance of the arc-shaped air guide plate 421, and then the tin-phosphor bronze belt of the upper and lower sections is auxiliary dried, thereby improving the utilization rate of the hot air, and the tin-phosphor bronze belt of the sponge pad 415 is continuously transported upward, and the second spring Under the squeezing action of 437, the movable drying plate 433 is abutted against the right side of the tin-phosphorus bronze strip, and the left side of the tin-phosphorus bronze strip is pushed to abut against the right side of the positioning drying plate 430. Under the action of the wavy scraper 434, the water film remaining on the surface of the transported tin-phosphorus bronze strip can be scraped more deeply, and the hot air transported in the second hot air duct 420 will be transported to the inside of each branch air hose 435, and then discharged through the fixed pipe 436, so as to deeply dry and blow the surface of the tin-phosphorus bronze strip, complete the cleaning and drying of the passivation liquid on the surface of the tin-phosphorus bronze strip, so that the passivation liquid will not drip into the outside world and affect the external working environment, and can improve a certain treatment effect.

[0061] Compared with the prior art, the surface passivation treatment equipment for tin-phosphor bronze strip, through the cooperation between the cleaning box 201, the passivation box 202, the winding mechanism 203 and the guide processing mechanism 300, can make the tin-phosphor bronze strip passivated after effective cleaning, so that the dust and dirt on the surface can be effectively removed. At the same time, by continuously introducing clean air into the inside of the cleaning box 201 and the passivation box 202, the activity of the cleaning liquid and the passivation liquid is improved, so that they can flow fully, thereby improving the cleaning effect and the effectiveness of passivation, that is, the passivation treatment effect of the tin-phosphor bronze strip is further improved, and the quality and stability of the finished product are guaranteed. By using the cleaning and drying mechanism 400, the passivation liquid inside the passivation box 202 can be cleaned. The tin-phosphor bronze strip after the liquid passivation treatment is dried. Through a segmented coordinated cleaning method, the water droplets on the surface of the tin-phosphor bronze strip are first scraped away, so that the surface will not carry large particles of water droplets, and then some water films will be formed. Then, the water film on the surface is adsorbed and dried by using a structural adsorption combined with a pre-blow water drying method, so that the surface of the tin-phosphor bronze strip can be in a relatively dry state. Finally, the surface of the tin-phosphor bronze strip is further deeply dried by a scraping and drying method, so that the passivation liquid on its surface can be fully dried and will not drip into the outside world to pollute the external working environment. The problem that the existing surface passivation treatment equipment for tin-phosphor bronze strips cannot effectively clean the passivation liquid remaining on the surface of the tin-phosphor bronze strip after the passivation treatment is completed is solved.
