The invention provides a coiled material preparation production line suitable for coating household appliances, which comprises a traction device, a spraying device 4 and a drying device 5 which are sequentially connected;
in order to better understand the various processes of the coil preparation production line of the present application, the process flow is explained here, firstly, the coil processed in advance is drawn by the drawing device, so that the coil is unfolded into a flat part, and is conveyed to the spraying device 4 through the first conveying belt for spraying, and then the coated plate after spraying is conveyed to the drying device 5 through the second conveying belt for drying; it should be noted that, in actual production, the coiled material that has handled in advance still need include washing process, air-dry process and passivation process to and after drying the completion, still need cut and can accomplish final production, the coiled material preparation production line of this application only explains and pulls, spraying and stoving partial process, and is specific, the structure of the coiled material preparation production line suitable for household electrical appliances application of this application is as follows:
as shown in fig. 1 to 6, the traction device comprises a power mechanism 1 and an output mechanism 2 which are sequentially installed, the power mechanism 1 comprises a driving assembly and a traction roller 10, and the output mechanism 2 comprises an installation roller 21 and an output roller 22;
the driving assembly is used for driving the traction roller 10 to rotate and enabling the traction roller 10 to abut against the coiled material arranged on the installation roller 21 so as to drive the coiled material to synchronously rotate and enable the coiled material to be pulled to the output roller 22;
a first conveying belt is arranged between the spraying device 4 and the output roller 22, and the first conveying belt is provided with a calibration mechanism 3;
the spraying device 4 is used for spraying the coiled material calibrated by the calibration mechanism 3;
and a second conveying belt is arranged between the drying device 5 and the spraying device 4, and the drying device 5 is used for drying the sprayed coiled material.
In this embodiment, the driving assembly drives the traction roller 10 to rotate, and since the traction roller 10 abuts against the coil mounted on the mounting roller 21, when the traction roller 10 rotates, a rotational force is synchronously applied to the coil to unfold the coil into a flat portion, in order to better draw the coil onto the first conveyor belt, the coil is guided by the output roller 22, so as to avoid that the flat portion is folded and pressed with the first conveyor belt when the coil is unfolded due to a height difference between the coil and the first conveyor belt, so that the flat portion is folded and folded, and the flat portion is folded and affects subsequent production, so that when the coil is actually mounted and produced, the upper surface of the output roller 22 should be kept on the same horizontal line with the belt body of the first conveyor belt;
after the coiled material is conveyed by the first conveying belt, the flat part of the coiled material has the deviation problem caused by the operation of the device, so the calibrating mechanism 3 is arranged, the coiled material can enter the spraying device 4 for spraying after being calibrated by the calibrating mechanism 3, and the problem of incomplete spraying caused by the position deviation of the coiled material is avoided;
after passing through the spraying device 4, the flat part of the coiled material is sprayed into a coating plate, and the coating plate enters a drying device 5 for drying through the conveying of a second conveying belt;
in the present application, the conveying of the first conveyor belt and the second conveyor belt is not shown in the figures.

In this embodiment, the traction roller 10 is mounted on the traction roller mounting frame 11 in a straddling manner, and the traction roller 10 can be driven to rotate by a driving device such as a driving motor, which is conventional technology, so that the description is only made in this application and is not shown in the drawings;
when a coiled material is installed on the installation roller 21, the first lifting cylinder 14 and the second lifting cylinder 15 are driven to synchronously adjust respective lifting air shafts so as to enable the traction roller installation frame 11 to swing, and further enable the traction roller 10 to abut against the surface of the coiled material; the swing mode of the traction roller mounting frame 11 can be as follows: the first lifting cylinder 14 and the second lifting cylinder 15 are used for providing lifting power, so that the traction roller mounting frame 11 swings up and down around the auxiliary rotating shaft 13, namely, when viewed from the side, the frame body of the traction roller mounting frame 11 swings around the auxiliary rotating shaft 13 as a circle center;
further, when the coiled material constantly opens out the back, the diameter of the periphery of the barrel that the coiled material formed is constantly reducing, means that the volume of coiled material is constantly dwindling, needs to adjust this moment pull the height of roller 10, make pull roller 10 can always with the coiled material takes place to contradict, can utilize pull roller 10 drives the coiled material takes place to rotate, adjusts the mode of pulling roller 10's height is the same with the above, does not do extra explanation here.
