For example, Chinese utility model patent with announcement number CN215002955U discloses a fixture for firing kiln shelf plates. The strength of the shelf plates with many circulation holes will be greatly affected, and they are prone to breakage when supporting the blanks, resulting in damage to the entire fired product. Utility Model Content

[0004] The utility model aims to solve the deficiencies of the prior art and provides a shelf support frame for firing.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] A shelf support frame for firing includes several layers of shelf boards, each shelf board is equipped with main support columns at the four corners of the bottom, each shelf board has four corners on the top and bottom of the shelf board and corresponding snap-in grooves corresponding to the main support columns, the main support columns of the upper shelf board are installed in the snap-in grooves of the lower shelf board, slideways are provided on the front and back sides of the top of the shelf board, several circulation shelf boards are provided on the top of the shelf board, and sliders are provided at the bottom of the circulation shelf board corresponding to the slideways and the sliders are slidably installed in the slideways.

[0007] A plug-in groove is provided in the middle of the bottom of each shelf plate, and an auxiliary support is provided between the upper plug-in groove and the upper surface of the lower shelf plate.

[0008] The beneficial effects of the utility model are as follows: the shelf of the utility model is equipped with a plurality of circulation racks through a slide, and the blank products are placed between the circulation racks, so that a heat circulation channel is formed between the blank products and the shelf, and the firing is more uniform, avoiding the influence of grooving on the shelf on the strength of the shelf, and making it more solid and durable.

[0017] As Figures 1 to 2 shown, a shed board support frame for firing includes a shed board 1, a main support column 2, a clamping groove 3, a slideway 4, a circulation shelf board 5, an insertion groove 6, and an auxiliary support column 7.

[0018] The shed board 1 has several layers. Main support columns 2 are installed at the four corners of the bottom of each shed board 1. Clamping grooves 3 are provided corresponding to the main support columns 2 at the four corners of the top and bottom of each shed board 1. The main support columns 2 of the upper shed board 1 are installed in the clamping grooves 3 of the lower shed board 1. Slideways 4 are provided on the front and back sides of the top of the shed board 1. Several circulation shelf boards 5 are provided on the top of the shed board 1. Sliders corresponding to the slideways 4 are provided at the bottom of the circulation shelf boards 5 and the sliders are slidably installed in the slideways 4.

[0019] The utility model installs a plurality of circulation racks 5 on the shelf 1 through a slide 4, and the blank products are placed between the circulation racks 5, so that a heat circulation channel is formed between the blank products and the shelf 1, and the firing is more uniform, avoiding the influence of too many circulation holes on the shelf 1 on the strength of the shelf, and making it more solid and durable.

[0020] The number of circulation racks 5 can be installed as needed, and the spacing can be adjusted to accommodate products of different widths, which is more flexible and diverse.

[0021] The depth of the slideway 4 is small to avoid causing a big impact on the structure of the shelf 1.

[0022] A plug-in groove 6 is provided at the middle position of the bottom of each shelf 1 , and an auxiliary support 7 is provided between the upper plug-in groove 6 and the upper surface of the lower shelf 1 .

[0023] After the blank product is placed on the shelf 1, pressure will be exerted thereon, especially in the middle position. Auxiliary pillars 7 can be installed as needed to play a role in strengthening the support.

[0024] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method.
