Abstract
Description
Technical Field
[0001] The invention relates to the technical field of galvanized sheet passivation treatment, and in particular to a galvanized sheet passivation treatment device and method. Background Art
[0002] Galvanized sheet passivation refers to a film-forming process used in the galvanizing process. Since zinc is an active metal, if it is not properly post-treated after galvanizing, the coating will easily darken and white corrosion products will appear. In order to reduce the chemical activity of zinc, passivation treatment is usually used to form a passivation film on the surface of the zinc layer. This film can isolate the metal from external oxygen and moisture, prevent the metal from oxidation reaction, and thus extend the service life of the metal.
[0003] During the use of the current galvanized sheet passivation treatment device, it is often necessary to clamp the top two sides of the galvanized sheet through multiple sets of clamping plates arranged relatively to each other. However, due to the presence of the clamping plates, the clamping part of the galvanized sheet is difficult to contact with the passivation liquid, which leads to incomplete passivation of the galvanized sheet and defects in the passivation reaction. After the passivation of the galvanized sheet is completed, a large amount of passivation liquid adheres to the side of the galvanized sheet. Since the passivation liquid is a strong acidic liquid, if it remains on the galvanized surface, it will corrode the zinc layer, destroy the protective effect, and affect the service life. The existing treatment method will transfer the galvanized sheet to a cleaning tank for rinsing, but this cleaning transfer reduces the efficiency of the passivation treatment.

A hydraulic push rod 2 is fixedly connected to the top wall of the top plate 1, and the movable end of the hydraulic push rod 2 is fixedly connected to the inverted circular plate 3.
[0030] A method for using a galvanized sheet passivation treatment device comprises the following steps: S1, open the hydraulic push rod 2, and transport the galvanized sheet downward to immerse it in the passivation tank; S2, turning on the motor 40 and energizing the magnetic spring 34, so that the two clamping plates 18 on the left and the two clamping plates 18 on the right in each switching mechanism alternately switch and clamp the galvanized sheet, thereby improving the passivation quality of the galvanized sheet; S3. After the passivation reaction of the galvanized sheet is completed, the hydraulic push rod 2 is turned on to move the galvanized sheet upward, and the micro motor 22 is turned on to make the two processing blocks 27 drive the corresponding scrapers 29 to fit against the surface of the galvanized sheet from both sides to scrape off the passivation liquid adhered to the surface of the galvanized sheet; S4, the magnetic spring 34 is powered off, the motor 40 is turned on, and the cleaning liquid sprayed from the flushing nozzle 30 can flush the clamping part of the clamping plate 18 on the galvanized sheet, and the cleaning liquid after cleaning will flow into the water storage tank 28 opened on the processing block 27.
[0031] In the present invention, the passivation tank is placed at the lower position of the device, and a positive current is passed through the electromagnet 50, so that the electromagnet 50 and the magnetic rod 49 have a magnetic attraction force on each other, then the magnetic rod 49 will slide a distance into the inside of the slide tube 13, and the contact position of the magnetic rod 49 and the trapezoidal plate 47 can be changed. Then, under the action of the reset spring 17, the two relatively arranged clamping plates 18 will be separated by a large distance, which is convenient for the galvanized sheet to be inserted from bottom to top into the two clamping plates 18 by the external transportation device. Then, a reverse current is passed through the electromagnet 50, so that the electromagnet 50 and the magnetic rod 49 have a magnetic repulsion force on each other, then the magnetic rod 49 will slide outward for a distance inside the slide tube 13, so that the two relatively arranged clamping plates 18 in each group of switching mechanisms clamp and fix the galvanized sheet, and then the hydraulic push rod 2 is turned on, and the movable end of the hydraulic push rod 2 drives the movable plate 46 to move downward in the vertical direction through the inverted C-shaped plate 3 fixedly connected thereto, thereby transporting the clamped galvanized sheet downward and immersing it in the passivation liquid for passivation reaction.
[0032] When it is necessary to switch the clamping part on the galvanized sheet to improve the passivation effect on the whole galvanized sheet, the motor 40 is turned on at this time, and the output end of the motor 40 drives the cross bar 41 to rotate, and the cross bar 41 drives the push column 42 to rotate synchronously, so that the push column 42 slides on the inner wall of the circular plate 43, then the circular plate 43 will drive the synchronous block 44 fixedly connected to it to reciprocate on the moving plate 46, then the synchronous block 44 will drive the two rectangular blocks 4 fixedly connected to it to reciprocate synchronously, when the two rectangular blocks 4 move synchronously to the left (such as Figure 3As shown in the figure, since each rectangular block 4 has a symmetrically provided inner wall with a wedge-shaped hole 5, the wedge-shaped hole 5 on the right side of each rectangular block 4 will drive the wedge-shaped block 7 embedded and sliding therewith to move downward for a certain distance, and the wedge-shaped block 7 will drive the trapezoidal plate 47 to move downward for a certain distance through the tension spring 10. Since the magnetic rods 49 in the two sliding cylinders 13 slide against the side walls of the trapezoidal plate 47, the two sliding cylinders 13 will rotate so that the ends of the two sliding cylinders 13 away from the trapezoidal plate 47 are close to each other, and each sliding cylinder 13 will drive the connecting rod 48 to slide for a certain distance through the connecting column 8 and the sliding hole 16, so that each connecting rod 48 drives the clamping plate 18 fixedly connected thereto to clamp the galvanized plate immersed in the passivation liquid, and then the wedge-shaped block 7 continues to move downward to squeeze one end of the tension spring 10.
[0033] At this time, the two relatively arranged clamping plates 18 on the right side of each switching mechanism will complete the clamping of the galvanized sheet, and in this process, the wedge-shaped hole 5 on the left side of each rectangular block 4 first causes the wedge-shaped block 7 embedded and sliding therewith to slide upward for a distance during the movement. At this time, since the corresponding tension spring 10 is in a compressed recovery state, the tension spring 10 can always provide elastic support force to the wedge-shaped block 7 during this process, and the stiffness coefficient of the tension spring 10 is much greater than the stiffness coefficient of the reset spring 17. Then, the wedge block 7 still drives the two relatively arranged clamping plates on the left side through the corresponding two sliding cylinders 13, the connecting column 8 and the connecting rod 48. The plate 18 clamps the galvanized sheet until the two clamping plates 18 on the right complete the clamping switch of the galvanized sheet, and the two relatively arranged clamping plates 18 on the left will be separated from the galvanized sheet, so that this clamping part of the galvanized sheet contacts the passivation liquid to produce a passivation reaction. Since the motor 40 is in the on state, the two clamping plates 18 on the left and the two clamping plates 18 on the right in each switching mechanism will switch and clamp the galvanized sheet alternately, so that the clamping part of the galvanized sheet can contact and react with the passivation liquid for a longer time, thereby avoiding the situation in the prior art that part of the area of the galvanized sheet is clamped for a long time and cannot contact and react with the passivation liquid.
[0034] During the reciprocating motion of each rectangular block 4, the toothed belt 6 symmetrically fixedly connected to the side wall of the rectangular block 4 will also drive the gear 20 meshing with it to rotate forward and reversely, and the gear 20 will drive the spline shaft 19 keyed to it to rotate, and the spline shaft 19 will drive the multiple stirring blades 39 fixed on the bottom side wall to rotate forward and reverse, thereby stirring the passivation liquid in the passivation tank, improving the uniformity of the passivation liquid, and improving the passivation quality of the galvanized sheet. During this process, the magnetic spring 34 is energized and contracted, so that the matching block 36 cannot contact the adjacent cam 31.
[0035] After the passivation reaction of the galvanized sheet is completed, the galvanized sheet needs to be taken out of the passivation tank. Then the galvanized sheet is moved upward by controlling the hydraulic push rod 2, and the micro motor 22 is turned on. The output end of the micro motor 22 drives the round rod 24 fixedly connected thereto to rotate a certain angle, so the round rod 24 will drive the switching rod 25 fixedly connected thereto to move a distance, and the switching rod 25 will drive the processing block 27 rotatably connected thereto to move. Since the processing block 27 is also rotatably connected to the circular frame 21 through the limit rod 26, the processing block 27 will be horizontally close to the galvanized sheet until the two processing blocks 27 drive the corresponding scrapers 29 to fit against the surface of the galvanized sheet from both sides. Then, the scraper 29 will scrape off the passivation liquid adhered to the surface of the galvanized sheet during the upward lifting process, so as to avoid the strong acidic passivation liquid from being attached to the side of the galvanized sheet in large quantities, and the passivation liquid remaining for a long time will corrode the galvanized layer and affect its service life.
[0036] Then, the magnetic spring 34 is de-energized, and after the magnetic spring 34 is de-energized, the corresponding matching block 36 and the adjacent cam 31 are in contact with each other, and the motor 40 is turned on. At this time, the spline shaft 19 can drive the matching block 36 that slides against it to move through the cam 31, so that the matching block 36 drives the sliding plug 35 fixedly connected to it to slide back and forth in the corresponding processing box 33 in a sealed manner, and then the cleaning liquid in the external water tank is pumped into the processing box 33 through the first one-way pipe 37, and then the cleaning liquid in the processing box 33 is squeezed into a plurality of flushing holes through the second one-way pipe 38. The cleaning liquid is sprayed out from the washing nozzle 30, and the sprayed cleaning liquid will contact the side of the galvanized sheet for washing. Since the multiple relatively arranged clamping plates 18 are still being switched at this time, the cleaning liquid sprayed from the washing nozzle 30 can wash the clamping part of the clamping plate 18 on the galvanized sheet, and then the side of the galvanized sheet can be covered and cleaned. The cleaning liquid after cleaning will flow into the water storage tank 28 opened on the processing block 27 to avoid falling into the passivation tank. The water storage tank 28 can be connected to the external collection pipe to collect the cleaning liquid after cleaning.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
