Description

Technical Field

[0001] This utility model relates to the field of funeral supplies technology, and in particular to a portrait frame for the deceased. Background Technology

[0002] A memorial portrait frame is a frame specifically designed to display photographs of the deceased. It is primarily used in funeral ceremonies, memorial sites, or family remembrance events, serving as a means to remember the deceased and express grief.

[0003] Existing picture frames are typically made of materials such as wood, MDF (medium-density fiberboard), and PS. These materials require painting or baking varnishing after processing. Therefore, the production process involves many steps, each requiring machinery and posing numerous safety hazards, especially the painting process, which leads to the emission of environmental pollutants. From a cost perspective, the cost is also relatively high. Furthermore, compared to paper, incineration takes longer and releases more environmental pollutants. Utility Model Content

[0004] The main purpose of this utility model is to provide a portrait frame that can effectively solve the problems of high cost and long incineration time.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A portrait frame for the deceased, comprising a paper frame assembled by folding;

[0007] The paper skeleton is folded and fixed by insertion or gluing through connecting holes to form a rectangular frame. The outside of the frame is covered with wood grain paper, cloth or environmentally friendly coating.

[0008] Preferably, the paper skeleton is made of corrugated paper or compressed cardboard.

[0009] Preferably, the components of the skeleton are cut into folded structures by a blade pressing process, and the cut areas do not completely penetrate the material.

[0010] Preferably, the frame includes four detachable and assembleable frame components. Each frame component is fixed by inserting a protrusion at its end and a protrusion at its end into an adjacent connecting hole and a connecting hole, forming the main body of the photo frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This portrait frame uses recyclable corrugated cardboard or compressed cardboard as the frame material, combined with an environmentally friendly coating and low-VOC glue. When burned, the emission of harmful substances such as dioxins and smoke is significantly lower than that of traditional wooden / PS frames. It also burns quickly and leaves no solid residue, meeting the environmental protection requirements of the funeral industry.

[0013] 2. This portrait frame does not require complex processes such as painting and polishing. It can be formed by semi-cutting, folding and plugging, reducing equipment investment and labor costs. At the same time, the detachable structure facilitates transportation and storage and has strong adaptability. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1 and Figure 2 As shown, a portrait frame includes a paper frame 1 formed by folding and assembling. The frame is made of corrugated paper or compressed cardboard with a material thickness of 2-5 mm. The components of the frame are cut into folded structures by a blade pressing process. The cutting depth is 30%-60% of the material thickness, and the cutting area does not completely penetrate the material to facilitate folding.

[0019] In addition, the frame includes four detachable and assembleable frame components. Each frame component is fixed by inserting protrusion 2 and protrusion 3 at its end into the mating holes 4 and 5 of the adjacent frame. Protrusion 2 is a trapezoidal structure with a slope of 15°-30°. The diameter of mating hole 4 is 0.5-1mm smaller than the maximum width of protrusion 2 to form an interference fit. Protrusion 3 and mating hole 5 adopt a tenon structure with a tenon length of 10mm and a mortise depth of 8mm to ensure that the verticality error of the assembled frame is ≤0.5°.

[0020] The outer side of the frame is covered with wood grain paper, fabric, or an environmentally friendly coating. The covering material is glued with environmentally friendly adhesive with a volatile organic compound content of ≤50g / L, which enhances the texture while ensuring that no toxic gases are emitted during incineration.

[0021] The assembly method for this portrait frame is as follows:

[0022] 1. Material preparation: Taking a standard 4R size [10×15cm] photo frame as an example, select 3-layer corrugated paper [total thickness 3mm] or 5mm compressed cardboard and cut it into 200×300mm boards;

[0023] 2. Sheet cutting: Use a CNC cutting machine to cut the sheet to half depth at a speed of 50-80mm / s.

[0024] A. The trapezoidal protrusion has an upper base of 2mm, a lower base of 5mm, a height of 8mm, and a slope of 22°;

[0025] B. The diameter of the connecting hole 4 is 4.5mm, and the edge of the hole is chamfered by 0.3mm;

[0026] C. The depth of the folding crease line is 45% of the material thickness [e.g., 1.35mm for cutting 3mm corrugated paper].

[0027] 3. Folding and assembly

[0028] A. Fold the sheet metal along the crease line to form the frame component, insert the protrusion 2 into the joint hole 4 of the adjacent frame, and press until the interference fit is locked.

[0029] B. The corner is connected to the tenon joint structure of the second protrusion 3 and the second joint hole 5, and a small amount of corn starch glue [solid content ≥30%] is added to enhance stability;

[0030] C. After the four sides are assembled, a rectangular frame is formed, with a verticality error of ≤0.5°.

[0031] 4. Surface treatment: Apply three layers of composite covering material to the outside of the skeleton using Henkel Pattrol environmentally friendly adhesive [VOC content 45g / L] and cure for 2 hours at 25℃ and 50% humidity.

[0032] A. Bottom layer: 120g / m 2 Waterproof kraft paper;

[0033] B. Middle layer: 0.2mm thick wood grain heat transfer film;

[0034] C. Surface layer: 0.1mm thick water-based anti-stick coating;

[0035] 5. Back panel installation: A honeycomb paper back panel is installed on the back of the frame and connected to the skeleton through a slot. The back panel has ventilation holes with a diameter of 1.5mm and a hole spacing of 12mm to facilitate the replacement of the portrait and air circulation.

[0036] It should be noted that the specific installation methods, circuit connection methods, and control methods of corrugated paper, compressed cardboard, and CNC cutting machine in this utility model are all conventional designs, and will not be described in detail in this utility model.
