The implementation principle of the embodiment is as follows:

the transmission motor 35 is started to drive the second transmission roller 34 to rotate through the meshing of the first transmission gear 36 and the second transmission gear 37, and the second transmission roller 34 is used as a driving roller to pull the metal coiled material so as to drive the metal coiled material to be pulled and transmitted in the previous process. In this process, the first conveying roller 33 can limit the metal coil, so that the metal coil is not easily scraped with the floor 1 around the through hole 32.

When the metal coil is pulled by the second conveying roller 34, the second conveying roller 34 and the first rubber roller 46 clamp the metal coil, so that the metal coil is attached to the first rubber roller 46. At this time, the first coating device 4 is in an activated state, the first driving motor 47 drives the first belt roller 45 to rotate through the engagement of the first driving gear 48 and the first transmission gear 49, so as to actively take up the coating material in the first tray 43 through the first belt roller 45. Because the first belt material roller 45 is contacted with the first rubber roller 46, the coating material on the first belt material roller 45 can be transferred onto the first rubber roller 46, and the coating material on one rubber roller is transferred onto the metal coil through the interaction force between the first rubber roller 46 and the second conveying roller 34, namely the coating on one side of the metal coil is finished.

On the other hand, when coating a metal coil, the amount of coating needs to be controlled, but if the first tape roll 45 can pick up a large amount of coating material in an indefinite amount, the amount of coating material that the first tape roll 45 can transfer to the first glue roll 46 also varies. At this time, the first driving lever 522 is rotated by rotating the first driving handwheel 524, so that the first driving bevel gear 523 is driven to rotate by the first driving lever 522, and the first driving bevel gear 523 can drive the first driven bevel gear 526 engaged with the first driving bevel gear to rotate and drive the first driven lever 525 to rotate by the first driven bevel gear 526. Since the first driven rod 525 and the first metering mounting frame 51 are in threaded connection, and the first driving shell 521 and the first frame 42 are fixedly connected, the rotation of the first driven roller can push the first metering mounting frame 51 to slide along the first slide rail 5, so as to adjust the abutting degree of the first metering roller 53 and the first rubber roller 46. The excessive coating material on the first rubber roller 46 can be extruded by the tight contact between the first metering roller 53 and the first rubber roller 46, and the tight contact between the first adjusting roller and the first rubber roller 46 can be adjusted, so that the amount of the coating material on the first rubber roller 46 can be adjusted, and the amount of the coating material transferred to the metal coil by the first rubber roller 46 can be controlled.

In addition, the coating on the first metering roll 53 is easily rotated by the first metering roll 53 and is transferred to the first glue roll 46 again, rather than falling into the first tray 43. The coating material transferred again to the first rubber covered roll 46 is also transferred to the metal coil, and since the amount of coating material transferred to the first rubber covered roll 46 by the first metering roll 53 is not controllable, the amount of coating material transferred to the metal coil by the first rubber covered roll 46 is also not controllable, resulting in uneven coating and affecting the coating quality. The first scraper 55 can scrape off the coating material on the first metering roller 53, so that the coating material on the first metering roller 53 falls into the first tray 43, thereby improving the stability of the first rubber roller 46 transferring to the coating material on the metal coil.

And through rotating adjustment handle 414, adjusting rod 413 can be driven to rotate, and because adjusting rod 413 and guide rail 411 threaded connection, the rotation of adjusting rod 413 can drive first frame 42 to slide along guide rail 411, makes the degree of support between first rubber roll 46 and second conveying roller 34 change to can adjust the distance between first rubber roll 46 and second conveying roller 34 according to the thickness of metal coil.

After the coating of one side of the metal coil is finished, the side of the metal coil which is not coated is attached to the second conveying roller 34, and is driven by the second conveying roller 34 to continue conveying and is in contact with the second rubber roller 65. During this process, the second coating device 6 is in the activated state. That is, the second driving motor 66 drives the second material taking roller 64 to rotate through the engagement of the second driving gear 67 and the second transmission gear 68, so as to actively take up the coating material in the second material tray 62 through the second material taking roller 64. The second material-carrying roller 64 transfers the coating material to the second rubber roller 65, so that the coating material is transferred to the side of the metal coil which is not coated to be coated, and then the double-side coating of the metal coil can be completed.

On the other hand, when coating a metal coil, the amount of coating needs to be controlled, but if the second tape roll 64 can pick up a large amount of coating material in an indefinite amount, the amount of coating material that the second tape roll 64 can transfer to the second glue roll 65 varies. At this time, the second driving rod 722 is rotated by rotating the second driving handwheel 724, so that the second driving bevel gear 723 is driven to rotate by the second driving rod 722, and the second driving bevel gear 723 can drive the second driven bevel gear 726 engaged with the second driving bevel gear 726 to rotate, and the second driven rod 725 is driven to rotate by the second driven bevel gear 726. Since the second driven rod 725 is in threaded connection with the second metering mounting frame 71, and the second driving shell 721 is fixedly connected with the second frame 61, the rotation of the second driven roller can push the second metering mounting frame 71 to slide along the second slide rail 7, so as to adjust the abutting degree of the second metering roller 73 and the second rubber roller 65. The second metering roller 73 and the second rubber roller 65 tightly abut against each other to extrude the redundant coating material on the second rubber roller 65, and the abutting degree of the second adjusting roller and the second rubber roller 65 is adjustable, so that the amount of the coating material on the second rubber roller 65 is also adjustable to control the amount of the coating material transferred to the metal coil by the second rubber roller 65.

In addition, the coating on the second metering roller 73 is easy to rotate under the driving of the second metering roller 73, and the coating is transferred to the second rubber roller 65 again instead of falling into the second tray 62. The coating material transferred to the second rubber covered roller 65 is also transferred to the metal coil, and the amount of the coating material transferred to the metal coil by the second rubber covered roller 65 is also uncontrollable because the amount of the coating material transferred to the second rubber covered roller 65 by the second metering roller 73 is uncontrollable, thereby causing uneven coating and affecting the coating quality. The second scraper 75 can scrape off the coating on the second metering roller 73, so that the coating on the second metering roller 73 falls into the second tray 62, and the stability of the coating transferred to the metal coil by the second rubber roller 65 is improved.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
