Description

Technical Field

[0001] The utility model relates to the field of aluminum foil processing, in particular to an aluminum foil coating device. Background Art

[0002] Aluminum foil is a hot stamping material that is directly rolled into thin sheets with metal aluminum. Its hot stamping effect is similar to that of pure silver foil, so it is also called fake silver foil. Aluminum foil is soft, ductile, and has a silvery white luster. If the rolled thin sheet is mounted on offset paper with sodium silicate and other materials to make aluminum foil, it can also be printed. In order to ensure that the aluminum foil has good processing resistance and corrosion resistance, the aluminum foil is generally coated.

[0003] Most of the existing aluminum foil coating devices generally pull out one end of the aluminum foil roll and install it on the winding device, so as to coat the double-sided or single-sided of the aluminum foil in the process of winding the aluminum foil to the winding device. However, since the aluminum foil is thin and light, once the aluminum foil is subjected to slight wind force or other forces in this process, it is easy to cause the aluminum foil pulled out from the aluminum foil roll to float slightly, thereby affecting the tension of the pulled aluminum foil, which is easy to affect the coating of the aluminum foil.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] An aluminum foil coating device comprises a stand, an upper extension plate is fixed to the upper end of the rear side of the stand, a mounting mechanism for loading the aluminum foil is mounted on the front end of the upper extension plate, and an operating mechanism for coating the upper and lower end surfaces of the aluminum foil;

[0007] The operating mechanism includes two limit rods, which are fixed in the middle of the front end surface of the platform. Two one-way screws are rotatably connected inside the upper extension plate. A third motor is installed at the input end of one of the one-way screws. Gears are fixed at the positions of the two one-way screws near the third motor, and the two gears are meshed with each other. Sliders are threadedly connected to the periphery of the two one-way screws, and the slides are slidably connected to the upper extension plate. A paint box is fixed at the front end of the slide, and a feed hopper is fixed at the upper end of the paint box. The corresponding ends of the two paint boxes are rotatably connected to coating rollers.

[0008] Preferably, the gap between the two limiting rods is located directly above the two coating rollers, and the diameter of the upper end of the feed hopper is greater than the diameter of the lower end thereof.

[0009] Preferably, the operating mechanism further comprises two electric heating racks, which are located below the lower coating roller and whose rear ends are fixed to the upper extension plate.

[0010] Preferably, the heating directions of the two electric heating racks correspond to each other, and there is a distance of fifteen centimeters between the two electric heating racks.

[0012] Preferably, the positions of the two splicing blocks on the upper extension frame correspond to the loading roller and the winding roller respectively, and a semicircular through groove is opened at one end of the splicing block corresponding to the loading roller and the winding roller.

[0013] The beneficial effects compared with the prior art are as follows:

[0014] When this device is in operation, if the pulled aluminum foil is subjected to other external forces, thereby affecting the tension, the two sliders are respectively threadedly connected to the two one-way screws and the slider is slidably connected to the upper extension plate. After starting the third motor, it can drive one of the one-way screws to rotate. At this time, through the mutual engagement of the two gears, when one of the one-way screws rotates, the other one-way screw can rotate in the opposite direction, so that the coating boxes at the front ends of the two sliders move in relative or opposite directions, so that the tension of the pulled aluminum foil can be adjusted, thereby preventing the pulled aluminum foil from being affected by other external forces and affecting the coating operation.
