AI Technical Summary
When the load weight of the existing annealing furnace is too high, the material tray will deform due to thermal expansion and contraction, which may lead to serious consequences.
A furnace bottom structure of annealing furnace carrying heavy load material trays is designed, including multiple columns extending upward through the bottom of the annealing furnace. A roller is provided at the top of the column, and the rollers are rolled between the bottom of the material tray and the columns to avoid heat. Expansion, cooling and contraction produces greater stress.
It effectively prevents deformation of the material tray during heat treatment, and the load capacity can reach about 140 tons, which is much higher than that of conventional annealing furnaces.

Abstract
Description
Technical Field
[0001] The utility model relates to an annealing furnace bottom structure, in particular to an aluminum foil annealing furnace bottom structure capable of bearing a heavy-loaded material tray. Background Art
[0002] Aluminum foil annealing furnace is used to anneal aluminum foil. Aluminum foil coils are generally placed on trays and fed into the annealing furnace. The current commonly used annealing furnace generally has a loading capacity of about 30 tons at a time, and a little more can reach 40 tons. It is rare to exceed 50 tons. The main reason is that the bottom of the tray is placed on the column in the annealing furnace. When the load is too high, the weight of the aluminum foil acts on the column through the tray, resulting in a lot of pressure between the tray and the column. When heat treatment is carried out in the annealing furnace, the tray cannot be expanded and contracted to adapt to the thermal expansion and contraction of the tray, resulting in deformation of the tray. Because the tray load is too high, the deformation of the tray may have unpredictable serious consequences. Summary of the invention
[0003] The utility model aims to provide an annealing furnace bottom structure for carrying heavy-loaded material trays, which can effectively prevent the material trays from being deformed during the heat treatment process, and has a load capacity much higher than that of conventional annealing furnaces.
[0004] In order to achieve the above technical purpose, the technical solution adopted by the utility model is:
[0005] The bottom structure of the annealing furnace carrying a heavy-loaded material tray includes a plurality of columns extending upward through the bottom of the annealing furnace, wherein the columns are arranged in two rows in the width direction of the annealing furnace, and the columns in each row are arranged in the length direction of the annealing furnace. The tops of the plurality of columns near the middle and both ends in the length direction of the annealing furnace in the two rows are provided with rollers capable of rolling on the tops of the columns, and the tops of the columns without rollers are flush with the upper parts of the rollers.
[0006] The above-mentioned annealing furnace bottom structure that carries a heavy-loaded material tray also includes a positioning seat, which includes two guide plates with U-shaped grooves. The guide plates are located on opposite sides of the column, and the two guide plates are connected by a support plate. The bottom of the support plate is in contact with the top plane of the column, and the shaft diameter extending from both ends of the roller to both ends is located in the U-shaped groove.
[0007] In the above-mentioned annealing furnace bottom structure for carrying heavy-loaded material trays, the two rows of columns are located on the outside of the two guide rails in the annealing furnace in the width direction of the annealing furnace.
[0008] The beneficial effects of the utility model are as follows: rollers are arranged on the tops of multiple columns near the middle and both ends in each row of columns, and the tops of the columns without rollers are flush with the upper parts of the rollers, so that rollers are provided between the middle and both ends of the bottom of the material tray and the columns, and when the material tray expands and contracts due to heat and cold, the rollers can roll on the columns and basically will not limit the expansion and contraction of the material tray, so the inside of the material tray will not be deformed due to large stress generated by thermal expansion and contraction, and the load capacity of the material tray can reach about 140 tons.
[0009] The roller can be positioned on the column by using a positioning seat to prevent the roller from rolling arbitrarily when there is no material tray in the annealing furnace. At the same time, the positioning seat does not limit the rolling of the roller on the top plane of the column. The positioning seat can move on the top plane of the column as the roller rolls.
[0010] The two rows of columns are located outside the two guide rails in the width direction of the annealing furnace, so that a trolley can run on the guide rails. When the tray enters and exits the annealing furnace, the tray is located on a lifting platform on the trolley that can be raised and lowered. The trolley moves on the guide rails to enable the tray and parts such as aluminum foil rolls on the tray to enter and exit the annealing furnace. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The specific implementation of the utility model is further described below according to the accompanying drawings:
[0017] like Figure 1-2 As shown, the annealing furnace bottom structure carrying heavy-loaded material trays includes a plurality of columns 1 extending upward through the bottom of the annealing furnace. The columns are arranged in two rows in the width direction of the annealing furnace. The two rows of columns are located on the outside of two guide rails 2 in the annealing furnace in the width direction of the annealing furnace.
[0018] The columns in each row are arranged in the length direction of the annealing furnace. The columns in the two rows near the middle and both ends of the length direction of the annealing furnace are short columns 11 with relatively low heights, and the other columns are tall columns 12. The tops of the short columns 11 are provided with rollers 3 and positioning seats that can roll on the tops of the short columns, and the tops of the tall columns 12 without rollers are flush with the upper parts of the rollers 3.
[0019] See also Figure 3-5 The positioning seat includes two guide plates 4 with U-shaped grooves 41, the guide plates 4 are located on opposite sides of the short pillar 11, and the two sides of the two guide plates are connected by support plates 5, the bottom of the support plate 5 is in contact with the top plane of the short pillar 11, and the shaft diameter 31 extending from both ends of the roller 3 to both ends is located in the U-shaped groove 41. The diameter of the shaft diameter 31 is slightly smaller than or equal to the width of the U-shaped groove 41.
[0020] The material tray 7 loaded with the aluminum foil roll 6 is placed on the high column 12 and the roller 3.
