Description

Technical Field

[0001] The utility model relates to the technical field of radiation processing, and specifically relates to a metal support plate for radiation processing. Background Art

[0002] Radiation processing is a process of irradiating processed articles with γ-rays spontaneously emitted by radioactive isotopes (cobalt-60 or cesium-137), high-energy electron beams generated by electron accelerators, or X-rays generated by electron beam hitting targets, so as to improve their quality or performance. It has been widely used in industries such as disinfection and sterilization of healthcare products, irradiation modification of polymer materials, and food irradiation preservation.

[0003] The production environments, constituent materials, packaging structures, and expected functions of processed articles are different, and their radiation processing requirements are also different. Generally, they can be summarized by the maximum acceptable dose and the required minimum dose. The ratio between the maximum acceptable dose and the required minimum dose (hereinafter referred to as the dose non-uniformity) can be used to measure the difficulty of the product irradiation process. The smaller the ratio, the more difficult the product is to process. Since the structure of the irradiation device and the arrangement of cobalt sources are basically determined when installed, the dose distribution inside the irradiation container is also determined. To meet the irradiation process requirements of products with low dose non-uniformity, special loading modes such as partial loading and intermediate loading are required to place the product in a specific space area inside the irradiation container, and this specific space area has excellent dose non-uniformity.

[0004] To meet the needs of the special loading mode of products, fillers with appropriate heights are commonly made of materials such as polyethylene, polystyrene, or corrugated paper, and the products are placed on the fillers to meet the space control requirements during product irradiation. After long-term use, the rays will damage materials such as polyethylene, polystyrene, and corrugated paper. These materials will gradually form fine powder during use and fall into the storage well in the irradiation room, resulting in unqualified water quality of the storage well, and further affecting the safety of cobalt sources.

[0005] Therefore, there is an urgent need in the market for a product support structure that can meet the space control requirements of product irradiation and at the same time does not affect the water quality of the storage well of the irradiation device. Summary of the Utility Model

By bending three of the broken lines, the bending surface is folded into a support foot in the shape of a right-angled column or a triangular column, and weight-reducing holes or weight-reducing grooves are evenly distributed on the support plate body.

[0008] Preferably, when the broken line is a right-angled broken line, the bending surface is bent by the right-angled broken line to form a right-angled column. A support bar is provided on the outer side edge of the bending surface. The upper surface of the right-angled broken line is a plane, and a 90-degree bending notch is provided on the lower surface.

[0027] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0028] The present utility model provides a metal support plate for radiation processing. Specifically, refer to Figure 1 , and its difference from the prior art is that: a support surface 11 is provided in the middle of the support plate body 1 of the support plate. On both sides of the support surface 11 are symmetrically arranged bent surfaces 14. On each of the two bent surfaces, a symmetrically arranged broken line group is provided. Each broken line group includes several broken lines 21 arranged parallel to each other. By bending three of the broken lines, the bent surface is folded into a support foot of a right-angled column or a triangular column. Uniformly distributed weight reduction holes 22 or weight reduction grooves 23 are provided on the support plate body. Here, the right-angled column refers to a square or rectangular column, and each interior angle is a right angle.

[0029] In use, the metal support plate of the utility model is made of pure aluminum. The bent surfaces 14 on both sides are processed by folding along the broken lines to form left and right symmetrically arranged support feet. The left and right support feet are provided with support surfaces, forming a firm and stable support structure, which can load and effectively support the irradiated products. At the same time, the entire metal support plate is provided with weight-reducing holes or weight-reducing grooves, which not only reduce the weight of the support plate, but also reduce the blockage of rays and improve the ray utilization rate.

[0030] Embodiment 1

[0031] In this embodiment, a support surface 11 is provided in the middle of the support plate body 1. The two sides of the support surface are bent surfaces 14. A pair of symmetrically arranged broken line groups are respectively provided on the two bent surfaces. Each broken line group includes several mutually parallel broken lines. By folding three of the broken lines, the bent surface is folded into the left support foot 12 and the right support foot 13 of a right-angled column. The support plate body is provided with uniformly distributed weight-reducing holes 22.

[0032] Specifically, every three corresponding right-angled broken lines can fold the bent surface into a right-angled column. The same color can be applied to every three corresponding right-angled broken lines for convenient folding. The right-angled broken lines at different positions can form right-angled columns with different heights and sizes, so that the metal-made plate can meet the space loading requirements of different products.

[0033] Furthermore, a support strip is provided on the outer side edge of the bent surface, so that the bent surface and the support surface can be well connected. The bent surface can effectively support the support surface and strengthen the bearing capacity of the entire support surface. The right-angled broken line here is only the broken line that can form a 90-degree right angle after folding. The upper surface of the right-angled broken line 211 is a plane, and a 90-degree bent notch is provided on the lower surface, so that the 90-degree fold angle formed after folding is relatively firm.

[0034] Furthermore, as Figure 1 shown, the plate body is made of a whole-piece pure aluminum plate with a thickness of 1.4 mm, a length of 1200 mm, and a width of 900 mm. Circular holes with a diameter of 5 mm are evenly opened on the plate body, and the distance between the holes is 5 mm. The two ends of the plate body are right-angled folded three times at an interval of 100 mm to form left and right support feet with a height of 100 mm, and a flat support surface with a length of 1200 mm and a width of 300 mm is formed at the top of the plate body.

[0035] Furthermore, within a range of 5 mm on both sides of each folding line at both ends of the plate body, no holes are opened.

[0036] Preferably, the folding distance at both ends of the plate body is adjustable, forming left and right support feet with heights ranging from 50 mm to 150 mm. The support surface has a length of 1200 mm and a width of 100 - 500 mm, which can meet the space loading requirements of different products.

[0037] Specifically, the utility model has the following beneficial effects:

[0038] 1. The support plate of the utility model is made of metal material, has excellent radiation resistance, can be reused repeatedly, and reduces the radiation cost.

[0039] 2. The plate body is evenly perforated at a certain interval. While ensuring the bearing strength of the plate body, the weight of the plate body is reduced, and the radiation dose can be directly increased by about 5%, which has good economic benefits.

[0040] 3. The metal support plate of the utility model is folded from an integrated plate body, and a 5-mm interval is reserved at both ends of each fold line without perforation, which can effectively ensure the support strength of the plate body.

[0041] 4. The folding distance at both ends of the plate body is adjustable, and support feet with different heights and support surfaces with different widths can be formed, which can meet the space loading requirements of different products.

[0042] Embodiment 2

[0043] In this embodiment, a support surface 11 is provided in the middle of the support plate body 1 of the support plate. The two sides of the support surface are bending surfaces 14. A pair of symmetrically arranged fold line groups are respectively provided on the two bending surfaces. Each fold line group includes a plurality of fold lines 21 arranged in parallel. By bending three of the fold lines, the bending surface is folded into the support feet of a triangular column. The support plate body is provided with uniformly distributed weight-reducing holes or weight-reducing grooves.

[0044] Specifically, the thickness of the plate body reaches 2 mm. Here, the fold line is a triangular fold line. Every three mutually cooperating triangular fold lines can be painted the same color to facilitate the user's bending treatment. After being bent by the triangular fold lines, the bending surface forms an equilateral triangular column. A support bar is provided on the outer side of the bending surface. The upper surface of the triangular fold line is a plane, and a 120-degree bending notch is provided on the lower surface, so that the 60-degree fold angle formed after bending is relatively firm.

[0045] Furthermore, the aperture of the weight-reducing hole is 4-6 mm, and the adjacent hole spacing is 4-5 mm; the groove diameter of the weight-reducing groove is 4-6 mm, and the adjacent groove spacing is 5-6 mm. The range within 3-5 mm on both sides of each fold line is a non-weight-reducing area. No weight-reducing holes or weight-reducing grooves are provided in the non-weight-reducing area, and a reinforcing plate or a reinforcing rib is provided in the non-weight-reducing area. The area ratio of the support surface to the bending surface is 1:1.5-3. The support plate body is made of pure aluminum. Compared with materials such as polyethylene, polystyrene, and corrugated paper, the radiation resistance of the plate body is greatly improved, which is beneficial for long-term use and has no pollution to the storage source well water of the radiation device; at the same time, compared with other metals, the density of aluminum metal is light, and the ray blocking effect is small, which can minimize the influence of the metal plate body on the ray utilization rate.
