Hereinafter, the operation of the coating liquid automatic recovery device 100 according to the present invention.

When coating the plated strip 1 with the chromium liquid 9, when the thickness is 1.0 mm or more, the coating liquid automatic recovery device 100 according to the present invention is operated to guide the guide screw 90 of the guide unit 90. Motor 99 coupled to both ends of 92 is actuated.

By the operation of the motor 99, the suction roll 11 of the suction unit 10 is advanced along the guide screw 92 toward the center of the strip (1). At this time, when the detection sensor 97 disposed above the device body 91 of the guide unit 90 detects the edge of the strip 1, the forwarding of the suction roll 11 is stopped, and the device is stopped. The cylinder 93 mounted on the rear side of the body 91 is operated so that the suction roll 11 is placed in contact with the surface of the strip 1.

Referring to FIG. 6, as the strip 1 progresses, the suction roll 11 abutting the strip 1 is rotated counterclockwise. When the suction roll 11 is rotated, a plurality of suction devices 20 mounted inside the suction roll 11 pass through the N pole magnet 36 mounted on the surface of the solution induction roll 31. When doing so, the S-pole magnet 22 mounted at the lower end of the suction devices 20 is drawn in the axial direction of the suction roll 11 by the magnetic force.

Referring to FIG. 3, the push plate 26 screwed with the connecting bar 23 is pulled in the axial direction by the axial drag of the S-pole magnet 22, and the sealing plate 27 is also in the same direction. Is pulled out. As the sealing plate 27 is pulled, a gap is formed between the sealing plate 27 and the rubber sealing plate 27a.

Therefore, the coating liquid 9 at the edge of the strip 1 flows into the suction roll 11 through the gap via the holes 11b of the surface of the suction roll 11.

Referring to FIG. 6, the coating liquid 9 flowing into the suction roll 11 is transferred to the solution induction tool 33 by a plurality of suction guide bands 15 mounted inside the suction roll 11. It is pumped up and sucked into the sponge roll 35 in the solution guide roll 31.

Meanwhile, referring to FIG. 2, as the suction roll 11 rotates, the second belt 75b integrally formed around the shaft 11a of the suction roll 11 is rotated and wound around the first belt 75c. ) Rotates, and the first pulley 75a integrally formed on the first rotation shaft 74a is rotated by this driving force. As the first pulley 75a is rotated, the second gear 76b integrally formed with the second rotation shaft 74b rotated and engaged with the first gear 76a integrally formed with the first rotation shaft 74a on the side. Is rotated. Rotation of the second gear 76b leads to rotation of the third pulley 77a integrally formed on the second rotation shaft 74b on the side, and thus the second belt 77c wound on the third pulley 77a. ) Is rotated. The fourth pulley 77b mounted around the shaft 45 of the rotary roll 40 is rotated by the rotation of the second belt 77c, and the rotary roll 40 is rotated accordingly.

As a result, referring to FIG. 6, when the suction roll 11 is rotated counterclockwise, the rotation roll 40 is rotated clockwise by the gear and the belt device of the rotation transmitting unit 70.

When the rotary roll 40 is rotated in the clockwise direction, the solution guide roll 41 is rotated clockwise while in close contact with the sponge roll 35 and thus the coating liquid 9 sucked into the sponge roll 35. Is squeezed out and discharged. The discharged coating solution 9 is guided counterclockwise on the solution collecting roll 51 as the solution guide roll 41 rotates and collected into the chamber 57 formed above the solution collecting roll 51. do.

The coating liquid 9 collected into the chamber 57 is discharged through the drop pipe 52 connected to the lower side of the chamber 57 and the suction roll through the discharge pipe 53 screwed to the drop pipe 52. (11) It is discharged to the outside.

Referring to FIGS. 7A and 7B, the coating liquid 9 discharged to the outside of the suction roll 11 passes through a drain pipe 81 and an expand pipe 83. 85 is collected and discharged to the outside through the drain pipe 87 connected to the drip pan 85 side.

Figure 7c is a perspective view showing the operation of the coating liquid automatic recovery device 100 according to the present invention.

Referring to FIG. 3, a rubber step 14 including a special rubber tube 16 is formed at an intermediate point of the rubber layer 17 of the suction roll 11, which forms a thick strip 1. In this case, the expansion of the special rubber tube 16 occurs in the direction of the arrow (right direction) while the suction roll 11 is rotated while closely contacting the strip 1, and thus the rubber layer 17 The outer shape is slightly deformed so that the coating liquid 9 exiting between the edge rolls of the strip 1 is completely squeezed and introduced into the suction roll 11 and eventually the remaining coating liquid 9 at the edge of the strip 1. This is completely removed.

Through a series of operations of the coating liquid automatic recovery device 100 according to the present invention as described above, the coating liquid 9 at the edge of the strip 1 is reliably automatically recovered to improve the quality of the strip 1.

As described above, according to the coating liquid automatic recovery apparatus of the strip edge according to the present invention, the coating liquid flowing to the strip edge automatically recovered in the conventional coating operation of the strip to prevent the coating liquid from scattering to the outside, and the atmosphere by the coating liquid There is a useful effect to prevent the breakdown of the peripheral equipment by pollution and surrounding transfer.

In addition, according to the coating liquid automatic recovery apparatus of the strip edge according to the present invention, there is a useful effect to prevent the drop mark is generated on the surface of the strip by the contaminated mass made of the coating liquid to improve the quality of the strip.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below.
