[0029] The shielding component 204 can shield the feed port of the heating furnace 1, reduce the heat loss inside the heating furnace 1, and achieve better use effect;

[0030] The unloading assembly 202 includes a rack 20201, a slide groove 205 is provided on the upper surface of the workbench 201, the rack 20201 is slidably connected inside the slide groove 205, a placement plate 20202 is provided on the upper surface of the rack 20201, a placement seat 206 is provided on the upper surface of the workbench 201, a driving motor 20203 is installed on the placement seat 206, a driving gear 20204 is installed on the output end of the driving motor 20203, and the driving gear 20204 is meshed and connected with the rack 20201;

[0031] When heating the workpiece, first place the workpiece on the upper surface of the placement plate 20202, and start the driving motor 20203 so that the output end of the driving motor 20203 drives the driving gear 20204 to rotate, and the driving gear 20204 pushes the rack 20201 to move in the slide groove 205 toward the end close to the heating furnace 1, so that the placement plate 20202 is located inside the heating furnace 1, and then the heating furnace 1 heats the workpiece on the placement plate 20202. After the workpiece is heated, start the driving motor 20203 so that the output end of the driving motor 20203 drives the driving gear 20204 to rotate, and the driving gear 20204 pushes the rack 20201 to move in the slide groove 205 toward the end away from the heating furnace 1, so that the placement plate 20202 is separated from the inside of the heating furnace 1, and the unloading of the workpiece is completed;
