[0020] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0021] like Figure 1 As shown, a specific embodiment of the utility model discloses an annealing furnace base, including a bottom plate 100, a support frame 200 fixedly arranged on the top surface of the bottom plate 100, the support frame 200 includes a support plate 240, the bottom surface of the support plate 240 is connected to the top surface of the bottom plate 100 by a plurality of support blocks, and a ventilation channel is left between the support plate and the bottom plate; a mesh frame 250 is fixedly arranged on the top surface of the support plate 240, and an air hole 260 connected to the ventilation channel is arranged on the empty bottom surface of the mesh frame 250.

[0022] The above-mentioned annealing furnace base has a novel structure and includes a bottom plate and a support frame fixedly arranged on the top surface of the bottom plate. The support frame includes a support plate. The bottom surface of the support plate and the top surface of the bottom plate are connected by multiple support blocks to provide stable support. A ventilation channel is left empty between the support plate and the bottom plate. A mesh frame is fixedly arranged on the top surface of the support plate. The empty bottom surface of the mesh frame is provided with air holes connected to the ventilation channel. The mesh frame serves as a direct contact part with the copper strip roll and can provide overhead support for the bottom of the copper strip roll. The ventilation channel is provided as a ventilation part. Hot air can enter from the ventilation channel and then be transported to the bottom of the copper strip roll through the air holes, thereby maintaining smooth ventilation, facilitating heat transfer, and improving the efficiency and quality of the annealing process.

[0023] Furthermore, an extension plate is provided at the edge of the base plate, and a through-hole is provided on the extension plate, so that the base plate can be fixed to the ground by bolts passing through the through-holes to provide a stable basic support; two annular grooves of different depths are provided on the top surface of the edge of the base plate to adapt to the furnace cover, provide alignment and the required basic sealing, and prevent the heat from being discharged.

[0024] Furthermore, the mesh frame 250 includes a plurality of convex rings 251 nested in sequence from the inside to the outside, and the convex rings 251 are connected by a plurality of convex strips 252, which extend in the radial direction of the support plate 240, and the plurality of convex strips 252 are distributed in an array around the central circumference of the support plate 240, and a plurality of grids 253 are formed between the convex strips 252 and the convex rings 251, and the air holes 260 are correspondingly arranged at the bottom of the grids 253; the convex rings and convex strips are used as raised supports to form an overhead area in the grid area, thereby preventing the bottom of the copper strip roll from blocking the air holes and maintaining the required ventilation; and the mesh structure formed by the convex rings and convex strips of the above-mentioned shape can effectively expand the coverage area and effectively enhance the overall structural strength.

[0025] Furthermore, a plurality of threaded holes are provided inside the convex ring located on the inner side of the support plate, and the plurality of threaded holes are distributed in an array around the central circumference of the support plate. On the one hand, they can be used as vents, and on the other hand, they can be used to install guide strips or interlayer brackets. When only a single-layer large coil is annealed, the guide strip can be used to install the guide strip so that the entire coil is placed along the guide strip to prevent deviation; when multiple coils are annealed, the interlayer bracket can be used to install the interlayer bracket to facilitate the distribution and placement of the coils and facilitate practical use.

[0026] Furthermore, the length of the air hole 260 in the grid 253 gradually increases from the center of the support plate 240 outward, and the air hole 260 is located at the center of the corresponding grid 253. Due to the different grid sizes, the corresponding air hole is matched according to the grid size to achieve better ventilation.

[0027] Furthermore, the support blocks are divided into a first support block 210, a plurality of second support blocks 220, and a plurality of third support blocks 230; the first support block 210 is disposed at the center of the support plate 240 to provide basic support for the center portion;

[0028] The second support block 220 is in the form of an elongated strip, and a plurality of second support blocks 220 are distributed in an array around the central circumference of the support plate 240, and the second support blocks 220 are arranged corresponding to the air holes 260; the support range is effectively expanded by means of a plurality of second support blocks, and the overall support effect is further enhanced; the third support blocks 230 are distributed in a plurality of groups, and a plurality of third support block groups are distributed in an array around the central circumference of the support plate, and the third support block groups are staggered and spaced apart from the second support blocks; a third support block group includes a plurality of third support blocks evenly spaced apart in the radial direction; the arrangement of the third support blocks can further enhance the overall support effect, and the spaced distribution can provide the necessary spacing to maintain the required gas transmission channel.

[0029] Furthermore, the second support block 220 gradually expands outward from the center of the support plate 240, and the second support block 220 is located on the center line of the corresponding air hole 260, and the corresponding air hole 260 is divided into two by the second support block 220; the opening part of the air hole is supported and strengthened by the second support block, and the second support block is gradually widened outward, which effectively prevents rupture when subjected to weight, strengthens the structural strength of the overall structure, and does not block the air hole position to prevent affecting normal ventilation.

[0030] Furthermore, the diameter of the third support block 230 of the same third support block group gradually increases in the direction away from the center of the support plate 240. Since the distance between two adjacent second support blocks gradually widens outward, the gradual increase in the third support block can strengthen the support for the middle part of the widened part, thereby maintaining the overall structural strength and support strength.

[0031] Furthermore, the third support block 230 is arranged at the intersection of the corresponding convex strip 252 and the convex ring 251. This design can achieve the correspondence between the upper and lower walls of the support plate, facilitate the transmission of force, and further enhance the overall structural strength.

[0032] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the claims of this application are within the scope of protection of the present invention.
