[0022] In actual use, the lifting device 4 further comprises two lifting synchronous wheels 44, one of which is arranged on the output shaft of the lifting motor 41, and the other is arranged on the rack 1. When the lifting motor 41 works, one of the lifting synchronous wheels 44 rotates, thereby driving the lifting synchronous belt 42 to convey, and thereby driving the lifting frame 43 to lift under the driving of the lifting synchronous belt 42. By controlling the rotating direction of the lifting motor 41, the lifting of the lifting frame 43 can be controlled. In order to facilitate speed control, a speed reducer is connected to the output end of the lifting motor 41, and the corresponding lifting synchronous wheel is arranged on the output shaft of the speed reducer.

[0023] In actual use, in order to facilitate the stable lifting of the lifting frame 43, two guide rails 10 are fixed on the rack 1 through screws, the two guide rails 10 are located on both sides of the lifting synchronous belt 42, the guide rail 10 is vertically arranged, and a sliding block is fixed on the lifting frame 43 and matched with the guide rail 10.

[0024] The first front-back conveying device 5 comprises a first motor 51, a first synchronous belt 52 and first synchronous wheels 53. The first motor 51 is arranged on the lifting frame 43. The first synchronous wheels 53 are two, one of which is sleeved on the output shaft of the first motor 51, and the other is arranged on the lifting frame 43. The first synchronous belt 52 is sleeved on the two first synchronous wheels 53. The first synchronous belt 52 corresponds to the second front-back conveying device 6, that is, the tray output by the second front-back conveying device 6 is conveyed onto the first synchronous belt 52.

[0025] The first synchronous belt 52 is two groups and is arranged in parallel. The first synchronous wheels 53 are correspondingly increased by two. The two groups of first synchronous belts 52 are connected by a rotating shaft between the corresponding front-back moving synchronous wheels, so as to facilitate synchronous conveying of the two groups of first synchronous belts 52.

Through cooperation of the jacking rod 33 and the oven, the jacking rod can be limited in position. The jacking rod and the jacking plate 32 can be prevented from rotating. Thus, when the third motor 31 is working, the jacking plate 32 can be lifted relative to the output shaft of the third motor 31.

[0028] Therefore, when the lowermost tray needs to be unloaded, the third motor 31 is started, the lifting plate 32 and the top rod 33 are pushed to move upward, the top rod 33 acts on the tray upward, and the whole stack of trays is supported, at this time, the cylinder 21 drives the baffle 22 to move to both sides, and the blocking of the tray is released; then, the third motor 31 is reversed, so that the top rod 33 supporting the tray moves downward, when the lowermost tray is lowered to below the baffle 22, the baffle 22 is pushed out under the action of the cylinder 21, and the remaining trays except the lowermost tray are prevented from continuing to move downward under the action of the baffle 22; when the tray is placed on the second synchronous belt 62 under the action of the lifting device 3, the tray is lowered to the position; then, the second motor 61 rotates, so that the tray is driven by the second synchronous belt 62 and moves to the first synchronous belt 52, and the tray is unloaded in the oven. When the tray is moved to the first synchronous belt 52, the corresponding equipment outside can take the roasted product from the tray. Then, the lifting motor 41 is started, the lifting frame 43 is driven to move downward, so that the whole first front and rear conveying device 5 moves downward, and the tray on the first synchronous belt 52 moves downward synchronously; when it is lowered to the position, the first motor 51 drives the first synchronous belt 52 to convey the tray to the next station.

[0029] The tray unloading mechanism also comprises a mounting frame 20, the mounting frame 20 is fixed on the lifting frame 43 through screws, and the first front and rear conveying device 5 is arranged on the mounting frame 20.

The limiting roller 8 is arranged along the length direction of the first synchronous belt 52, the limiting roller 8 can limit the tray on the first synchronous belt 52, and meanwhile, the movement of the tray is facilitated, and the frictional force on both sides is reduced.

[0031] The above is only a preferred embodiment of the present application, and it should be pointed out that, for ordinary skilled persons in the art, without departing from the creative concept of the present application, a plurality of modifications and improvements can be made, which all belong to the protection scope of the present application.
