Description

Technical Field

[0001] The invention relates to the technical field of steel strip electroplating, and in particular to a steel strip electroplating device. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. During electroplating, the plating metal or other insoluble materials serve as the anode, and the workpiece to be plated serves as the cathode. The cations of the plating metal are reduced on the surface of the workpiece to be plated to form a plating layer. In order to eliminate the interference of other cations and make the plating uniform and firm, a solution containing the plating metal cations is required as the electroplating solution to keep the concentration of the plating metal cations unchanged. The purpose of electroplating is to plate a metal coating on the substrate to change the surface properties or size of the substrate. Electroplating can enhance the corrosion resistance of metals, increase hardness, prevent wear, and improve conductivity, smoothness, heat resistance and surface beauty.

When the upper end surface of the steel belt contacts, the upper baffle 22 can squeeze the upper switch 211 so that the upper switch 211 is turned on, and then the liquid sprayed by the upper nozzle 221 flushes down part of the impurities on the upper end surface of the steel belt, and then the upper baffle 22 is separated from the squeezing of the upper switch 211, and then the lower end surface of the upper baffle 22 contacts the upper end surface of the steel belt, and the unlocking block 251 is inserted into the socket 1 again under the action of the elastic member 2, and the upper rack 26 is meshed with the gear 1 271 again, and the elastic member 1 is in the state of storing force again.

At this time, the lower rack 36 is meshed with the second gear 371, and the elastic member 3 is in a state of storing force. It should be noted that the speed at which the motor 2 drives the lower rack 36 to move is consistent with the moving speed of the steel belt; the lower guide plate 31 has a lower guide surface for sliding the lower baffle plate 32, and the lower guide surface is arc-shaped. The lower guide surface is equipped with a 321 sprays liquid from the lower switch 311, the lower switch 311 is used to control the start and stop of the water pump 1, when the lower baffle 32 slides along the lower guide surface, it can squeeze the lower switch 311 so that the lower switch 311 is opened and stored in the lower guide plate 31, at this time, the electrolyte in the tank body 10 is transported to the lower nozzle 321 through the water pump 1, so that the liquid sprayed by the lower nozzle 321 can wash down a part of the impurities on the lower end surface of the steel strip, when the lower baffle 32 is separated from the squeezing of the lower switch 311, the lower switch 311 can be reset, and at this time the lower nozzle 321 stops spraying liquid, it should be noted that when the upper baffle 22 squeezes the upper switch 211, the lower baffle 32 also squeezes the lower switch 311 synchronously, and when the upper baffle 22 is separated from the squeezing of the upper switch 211, the lower baffle 32 is synchronously separated from the squeezing of the lower switch 311.

[0034] The lower baffle plate 32 is in the process of being in contact with the lower end surface of the steel belt on one side toward the lower end surface of the steel belt, and as the lower baffle plate 32 moves synchronously with the steel belt, when the lower baffle plate 32 stops against the unlocking piece 2 35, the lower elastic telescopic rod 34 is in a contracted state, and the unlocking piece 2 35 disengages from the insertion hole 2. At this time, the elastic piece 3 can quickly drive the lower elastic telescopic rod 34 to swing downward, so that the lower baffle plate 32 is disengaged from the contact with the steel belt downward, and then the lower rack 36 is disengaged from the meshing with the gear 2 371, and then under the action of the third spring, the lower elastic telescopic rod 34 extends and causes the lower baffle plate 32 to slide along the lower guide surface, and the side of the lower baffle plate 32 facing the lower end surface of the steel belt is about to be in contact with When the lower end surface of the steel belt contacts, the lower baffle plate 32 can squeeze the lower switch 311 so that the lower switch 311 is opened, and then the liquid sprayed by the lower nozzle 321 flushes down part of the impurities on the lower end surface of the steel belt, and then the lower baffle plate 32 is separated from the squeezing of the lower switch 311, and then the lower baffle plate 32 contacts the lower end surface of the steel belt on the side facing the lower end surface of the steel belt, and the unlocking block 2 351 is inserted into the socket 2 again under the action of the elastic member 4, and the lower rack 36 is meshed with the gear 2 371 again, and the elastic member 3 is in the state of storing force again. It should be noted that at this time, there are no impurities remaining at the position where the lower baffle plate 32 contacts the lower end surface of the steel belt on the side facing the lower end surface of the steel belt.

[0035] like Figure 1 , Figure 8 and Fig. 9 As shown, an upper roller 51 for cleaning the upper surface of the steel strip and a lower roller 61 for cleaning the lower surface of the steel strip are rotatably installed between the two support rods 11, and a driving member 3 70 for controlling the rotation of the upper roller 51 and the lower roller 61 is installed on one of the support rods 11. The driving member 3 70 is a motor 3, and a gear 3 is installed at the output end of the motor 3. A gear 4 meshing with the gear 3 is coaxially fixedly installed on one side of the upper roller 51, and a gear 5 meshing with the gear 3 is coaxially fixedly installed on one side of the lower roller 61. A plurality of upper sponge strips 52 are arranged at intervals on the periphery, an upper plate 53 for squeezing out the liquid in the upper sponge strips 52 is fixedly mounted on the support rod 11, a plurality of lower sponge strips 62 are arranged at intervals on the periphery of the lower roller 61, a lower plate 63 for squeezing out the liquid in the lower sponge strips 62 is fixedly mounted on the support rod 11, along the moving direction of the steel belt, the upper roller 51 is located in front of the upper nozzle 23, the upper nozzle 23 is located in front of the upper baffle 22, the lower roller 61 is located in front of the lower nozzle 33, and the lower nozzle 33 is located in front of the lower baffle 32.

[0036] The upper plate 53 has an upper cavity therein, and the bottom surface of the upper cavity is inclined so that the liquid in the upper cavity can flow downward into the tank body 10. In this embodiment, a third tube connected to the upper cavity is installed on one side of the upper plate 53, one end of the third tube is close to the inclined end of the bottom surface of the upper cavity, and the other end of the third tube faces the tank body 10. The upper plate 53 has an inclined surface 1 that can be squeezed and contacted with the upper sponge strip 52 on the side facing the upper roller 51, and a plurality of upper through holes 531 connected to the upper cavity are opened on the inclined surface 1. When the roller 51 rotates rapidly, the upper sponge strip 52 can absorb the residual electrolyte on the upper end surface of the steel strip, and then when it is squeezed with the inclined surface, the upper sponge strip 52 can release the absorbed electrolyte into the upper cavity. The lower plate 63 is located below the lower roller 61, and a plurality of lower through holes 631 are provided on the lower plate 63. When the lower roller 61 rotates rapidly, the lower sponge strip 62 can be squeezed and contacted with the lower plate 63, so that the liquid in the lower sponge strip 62 can flow downward into the trough body 10 through the lower through holes 631.

[0037] In this embodiment, the upper roller 51 and the lower roller 61 both rotate counterclockwise (viewed from front to rear along the axial direction of the upper roller 51 ).

[0038] It should be noted that the upper baffle 22 has a guide portion 223 on the side facing the upper roller 51, and the guide portion 223 is triangular in shape, so that in the process of the lower end surface of the upper baffle 22 contacting the upper end surface of the steel belt, when the upper nozzle 23 sprays liquid to the upper end surface of the steel belt, the electrolyte can flush the impurities on the upper end surface of the steel belt along the upper end surface of the steel belt, and then under the action of the guide portion 223, the impurities can flow downward from the front and rear sides of the steel belt along the guide portion 223 into the filter frame 40.

[0039] Specific working principle: Reference Figure 1-Figure 9When the steel strip is discharged upward after being electroplated in the tank body 10, the waste floating on the surface of the electroplating solution in the tank body 10 will adhere to the upper and lower end surfaces of the steel strip and then be carried out, and there is also excess electroplating solution attached to the surface of the steel strip. In order to recycle this part of the electroplating solution and clean up the waste floating on the electroplating solution at the same time, the following steps are implemented: Step 1: First, the end of the steel strip output from the tank body 10 is passed around the shaft 12, and when the upper elastic telescopic rod 24 is in the longest state, the outer surface of a section of the steel strip located between the shaft 12 and the upper baffle 22 is rinsed clean with an electrolyte free of impurities; Step 2: Control the lower end surface of the upper baffle 22 to contact the upper end surface of the steel strip, and at the same time control the lower baffle 32 to contact the lower end surface of the steel strip on the side facing the lower end surface of the steel strip, and at this time control the motor 1 and the motor 2 to operate so that the upper baffle 22 and the lower baffle 32 move synchronously with the steel strip; Step 3: When the upper baffle plate 22 abuts against the unlocking piece 1 25, the lower baffle plate 32 abuts against the unlocking piece 2 35, so that the upper baffle plate 22 is disengaged from the contact with the steel belt upwards, and the lower baffle plate 32 is disengaged from the contact with the steel belt downwards, then the upper elastic telescopic rod 24 is extended and the upper baffle plate 22 slides along the upper guide surface, the lower elastic telescopic rod 34 is extended and the lower baffle plate 32 slides along the lower guide surface, when the lower end surface of the upper baffle plate 22 is about to contact the upper end surface of the steel belt, the liquid sprayed by the upper nozzle 221 flushes down a part of the impurities on the upper end surface of the steel belt, and the liquid sprayed by the lower nozzle 321 flushes down a part of the impurities on the lower end surface of the steel belt, then The lower end surface of the upper baffle 22 contacts the upper end surface of the steel strip, and the lower baffle 32 contacts the lower end surface of the steel strip on one side facing the lower end surface of the steel strip, and then the upper nozzle 23 and the lower nozzle 33 are controlled to spray liquid respectively. During this process, the electrolyte in the upper nozzle 23 can flush the impurities on the upper end surface of the steel strip along the upper end surface of the steel strip, and then under the action of the guide part 223, the impurities can flow downward from the front and rear sides of the steel strip along the guide part 223 into the filter frame 40, and the electrolyte in the lower nozzle 33 can flush the impurities on the lower surface of the steel strip into the filter frame 40, the flushed impurities will remain in the filter frame 40, and the electrolyte will flow back to the tank body 10 to be used.

[0040] Then, step three can be repeated to clean the impurities on the surface of the steel strip in sections. When the cleaned steel strip passes through the upper roller 51 and the lower roller 61, the upper sponge strip 52 and the lower sponge strip 62 can absorb the residual electrolyte on the surface of the steel strip. Then, when the upper sponge strip 52 is squeezed with the inclined surface and the lower sponge strip 62 is squeezed with the lower plate 63, the upper sponge strip 52 can release the absorbed electrolyte into the upper cavity, and then flow downward into the tank body 10 through the third tube, and the liquid in the lower sponge strip 62 can flow downward into the tank body 10 through the lower through hole 631.
