Description

a frame structure

The utility model relates to a photo frame and a picture frame, in particular to a frame bar structure of the photo frame and the picture frame.

In order to attract consumers' desire to buy, general photo frames and picture frames are often made with various patterns or line changes on the surface of the frame bars that form the frame to increase the appearance. Traditional photo or picture frames are mostly made of wood or metal frame strips. Due to the increasing scarcity of wood resources, the cost is high; and the metal frame strips are mostly straight lines due to the difficulty in processing, and the appearance is too monotonous. Therefore, the foamed plastic with lower cost is used as the raw material to make frame strips for photo frames or picture frames in the market at present. It uses the external foaming method to form a polystyrene base layer in the mold, and then forms an embossed layer on the surface of the base layer by heating embossing or hot rolling, and finally uses bronzing or paint on the surface of the embossed layer. Method Apply a processing layer. Although the material price of this kind of frame bar structure is relatively low, a variety of patterns or line changes can be obtained; but it has some defects as follows:

1. The accuracy of the heating process is not easy to control, and the frame strips are often deformed due to improper temperature control, which reduces the yield and increases the production cost.

2. The frame made of a single foamed plastic has low strength and is easily damaged by external force.

3. The surface of the embossed layer is rough and the three-dimensional effect is poor, so that the aesthetic effect of the processed layer is greatly reduced; in addition, due to the low strength of the foamed plastic, the pattern or line of the embossed layer is limited to make complex changes.

The purpose of the utility model is to provide a frame bar structure, which has high yield and low cost; high strength, not easy to damage; fine and clean surface, strong three-dimensional effect, suitable for manufacturing embossed layers with complex and changing patterns or lines.

The purpose of this utility model is achieved like this: a kind of frame structure, it comprises the base layer of foamed plastics and the processing layer that is coated on the outside, it is characterized in that the mixed layer between described base layer and processing layer is set, The above mixed layer is formed by mixing and stirring wood powder and binder.

The above-mentioned frame bar structure is characterized in that: a cold-pressed embossed layer is arranged on the surface layer of the mixed layer, and the above-mentioned processed layer covers the above-mentioned embossed layer.

In the utility model, a mixed layer formed by mixing sawdust powder and binder is added between the base layer of the foamed plastic and the outer processing layer. After the mixed layer is solidified, it not only has high strength, so that the frame bars are not easy to be damaged, but also has a smooth and delicate surface, so that the processed layer coated on it is dazzling. In the process of solidification and hardening of the mixed layer, the method of cold pressing can be adopted to form various embossed layers with complex and changing patterns or lines on the surface layer of the mixed layer. Because the mixed layer has good fluidity and plasticity before it is completely solidified and hardened, the pattern of the embossed layer is clear, the lines are full, and it is full of three-dimensional effect. There is no risk of deformation and scrap caused by thermal processing. In addition, the use of sawdust as a waste material from wood processing, which is ground into powder, not only reduces the cost of materials, but also turns waste into treasure, and is also beneficial to the improvement of the environment.

Below in conjunction with accompanying drawing, utility model is described further.

Figure 1 is a three-dimensional schematic diagram of a photo frame or picture frame using the utility model.

Fig. 2 is a schematic sectional view of the utility model.

Fig. 3 is a schematic diagram of the production process of the utility model.

The utility model comprises a base layer 1 and a processing layer 4 (seeing the second figure). The base layer 1 is located at the lowermost layer of the frame structure and is formed by foaming and pressing polystyrene. On the base layer 1, the mixed layer 2 formed by mixing and stirring the wood powder and the binder is bonded by the binder. The sawdust powder in the mixed layer 2 is the powder obtained by grinding waste material-sawdust produced in the wood processing process. During the above hardening process of the mixed layer 2, an embossed layer 3 can be formed on its surface by cold working. The above-mentioned embossed layer 3 can add changes in patterns and lines to achieve rich aesthetic effects. The processing layer 4 is coated on the embossing layer 3 and covers it, and the processing layer 4 can be bronzing or sprayed with paints of various colors.

The utility model manufacturing process is as follows (referring to the 3rd figure):

1. Plastic external foaming 51. In the mould, use polystyrene (or the waste material of polystyrene foamed plastic) to foam and extrude the molding base layer 1 .

2. Make the sawdust layer 52 . On the base layer 2, a mixed layer 2 formed by stirring wood powder and binder is set up.

3. Embossing53. Embossing is carried out on the surface of the mixed layer by cold pressing or flower wheel rolling. Since the wood powder and the binder are stirred and mixed, it will be completely hardened in about 3 hours. Therefore, embossing can be easily performed in desired patterns or lines. At the same time, the hybrid layer 2 is closely bonded to the base layer 1 .

Four. Bronzing 54. On the embossed layer 3, the processing layer 4 is made by hot stamping process. This operation also can adopt spraying various paints to make processing layer 4.

The utility model can be used to make photo frames and picture frames of various styles. Fig. 1 is a three-dimensional schematic diagram of an example.
