Detailed Description

The following description of the preferred embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1, the scroll heating art painting according to the present invention comprises a painting body 1, a buckle 2 and a shaft head 3, wherein each of two ends of the painting body 1 is respectively fixed in the shaft head 3 through two buckles 2, i.e. each of four angles of the painting body 1 is respectively fixed in the shaft head 3 through one buckle 2.

As shown in fig. 2, the easel 1 includes a graphene heating layer 11, and a first TPU layer 12 and a second TPU layer 13 coated outside the graphene heating layer. The easel 1 also includes an artistic canvas layer 14 attached to the first TPU layer 12 and a rare earth material adsorption layer 15 attached to the second TPU layer 13. In this embodiment, the painting body 1 is rectangular.

As shown in fig. 3, the graphene heat generating layer 11 includes a fiber woven body 111 and soft copper wires 112 woven in the fiber woven body 111. In particular, referring to patent application CN201810890616.9, the graphene heat-generating layer 11 is woven by weft yarns and warp yarns, for example, the weft yarns are graphene aramid fibers, and the warp yarns are flame-retardant fibers with a high flame-retardant coefficient and soft copper wires 112, wherein the graphene aramid fibers and the flame-retardant fibers are woven to form the fiber woven body 111, and the soft copper wires 112 are woven in the fiber woven body 111 as copper poles of the graphene heat-generating layer 11. The number of the soft copper wires 112 can be specifically calculated according to (total overload current) × s (number of soft copper wires), for example, the number of braided wires is at least 45, so that stable power output can be ensured. In addition, in order to control and adjust the temperature of the canvas, the graphene heating layer 11 further comprises a temperature control probe 113 woven in the middle of the heating area by using fiber materials such as externally non-conductive enameled wires, and since an insulating layer is arranged outside the enameled wires, the current cannot pass through a wire to influence the heating uniformity performance of the enameled wires in the use process, and simultaneously, since the density of heated air is lower than that of air with lower temperature, the heated hot air rises in the use process, and the temperature control probe 113 is arranged above the canvas to achieve the control range of the maximum temperature.

As shown in fig. 4, the clip 2 includes a base plate 21, two connecting plates 22 and two legs 23, wherein the two connecting plates 22 extend vertically upward from opposite sides of the base plate 21, respectively, at a distance from each other, and the two legs 23 extend forward and backward from ends of the connecting plates 22, which are far from the base plate 21, respectively. Wherein, a canvas notch 221 for accommodating the painting body 1 is formed between the two connecting plates 22, and the two connecting plates 22 are provided with corresponding reserved holes 222, so that the painting body 1 can be fixed between the two connecting plates 22 by fixing members (such as rivets or screws) passing through the reserved holes 222. In addition, the end surface 231 of the leg 23 remote from the connecting plate 22 is formed as a slope. In this embodiment, the clip 2 is an insulating clip.

As shown in fig. 5, the spindle head 3 has a cylindrical structure with an elongated cloth-engaging notch 31. As can be seen from FIG. 1, the notch 31 is opposite to the canvas notch 221 of the clip 2 so that the picture body 1 can be fixed by extending into it. In addition, since the end surfaces 231 of the legs 23 of the clip 2 are formed as slopes, which form four contact lines 231a with the inner surface of the stub shaft 3, the relative fixing of the clip 2 in the stub shaft 3 is more stable when bearing the external weight. In this embodiment, the stub shaft 3 is a metal stub shaft, for example formed of stainless steel or iron. In the present embodiment, the canvas slot 221 has a span (width) of 0.3 mm. In addition, the shaft head 3 can be provided with a fixing head (such as a pterocarpus santalinus fixing head) which is convenient for subsequent installation and fixing.

In this embodiment, the shaft head 3 includes an upper shaft head piece and a lower shaft head piece with similar structures, wherein the lower shaft head piece has a 220V power interface, correspondingly, the buckle 2 includes an upper buckle piece and a lower buckle piece with similar structures, wherein the lower buckle piece has a power interface, and the positions of the picture body 1 and the wire interface need to be coated with insulating glue, so that a rectangular clamping groove needs to be opened on one side of the lower buckle piece, so that the joint part can be conveniently clamped and then insulation can be realized by injecting the insulating glue. In addition, the diameter of the lower shaft head piece is 3-4 times that of the upper shaft head piece, the lower shaft head piece also needs to bear the effect of a balance weight and can provide constant tension to the cloth surface when in use, and the flatness of the cloth surface is ensured when in use.
