Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, the invention provides an aging furnace, which comprises a heat treatment chamber 1, a circulating fan 2 and an air guide device, wherein the heat treatment chamber comprises a hot air output layer 11, a heating layer 12 for heat treatment of a workpiece and an air direction area 13 for guiding the air direction, the air guide device is arranged at two sides of the heat treatment chamber, and hot air flows from the hot air output layer 11 to the heating layer 12 through the air guide device;

the air guide device comprises a winding sheet 3 for guiding, a guide rail for guiding the winding sheet 3 to extend out and a driving device for winding and unwinding the winding sheet 3, the guide rail is provided with a plurality of guide grooves 4 for guiding the winding sheet to move in a bending mode, and the driving device drives the winding sheet 3 to move along the guide grooves 4 so as to separate the wind direction area 13 into a plurality of layers of hot air channels 6.

Specifically, the driving device includes a reel 5 for winding the roll sheet and a motor (not shown in the drawings) for driving the reel to rotate. In order to avoid the influence of high temperature on the motor, one end of the reel 5 extends out of the furnace body to be driven by the motor.

The guide grooves 4 are provided on both side inner walls of the heat treatment chamber 1 in terms of the formation of the hot air passage by the rolled sheet. Therefore, when the coiled sheet is coiled back, the skip car for carrying the material to be heat-treated can freely enter and exit the furnace, so that the feeding and discharging are convenient.

The guide groove 4 comprises an inlet segment 41 corresponding to the hot air output layer, an outlet segment 42 corresponding to the heating layer and a curling segment 43, and the rolled sheet 3 sequentially passes through the inlet segment 41, the curling segment 43 and the outlet segment 42. It should be noted that the curling section is an arc section with a preset curvature, the arc section is not shown in the figure, and preferably, the guide groove 4 is C-shaped as a whole.

The outlet segments 42 of the respective guide grooves 4 are spaced apart in the vertical direction so that the heat seal is guided through the web 3 to form air outlets at a plurality of heights, thereby improving the uniformity of the heat seal blow.

In order to ensure the fluidity of hot air passing through the reels, all the reels 5 are distributed in an inclined manner, so that the adjacent reels 5 are spaced apart by a preset distance in the horizontal direction and the vertical direction. Thereby avoiding that all reels 5 are concentrated in the same vertical plane and seriously hamper the flow of hot air.

In order to improve the flow stability of the hot air after being guided by the rolled sheet, the outlet segment 42 is horizontally arranged, so that the hot air can obtain a section of straight steady flow after passing through the rolled sheet in the area of the curling segment 43.

Further, the end of the outgoing section 42 is provided with a U-shaped section 421 for changing the wind guiding direction, so that whether the winding sheet 3 passes through the U-shaped section 431 and moves to any position of the U-shaped section 421 can be controlled by controlling the extending length of the winding sheet 3.

It should be noted that, in the process that the rolled sheet 3 passes through the U-shaped section 431, the direction of the tail end of the rolled sheet 3 changes, so the direction of the hot air blown out can be controlled by the motor, and the rolled sheet can be repeatedly stretched out and rolled to achieve the function of sweeping the air up and down, thereby improving the heating uniformity in the furnace.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
