[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] A preferred embodiment of a multi-layer drying machine provided by the utility model is as follows: Figures 1 to 5 As shown: a multi-layer dryer includes a base 1, a dryer body 2 is arranged on the top of the base 1, the inner wall of the dryer body 2 is rotatably connected to a first conveyor mesh belt 3, the inner wall of the dryer body 2 is located on the side of the first conveyor mesh belt 3 and is fixedly connected to a blanking plate 4, and the surface of the dryer body 2 is provided with a layer changing mechanism 5.

[0028] In this embodiment, the first conveyor mesh belt 3 is provided with three groups, and the unloading plate 4 is inclined. By setting the unloading plate 4, because the unloading plate 4 is inclined, when the workpiece above the third layer of the first conveyor mesh belt 3 is dried, it will be above the conveyor belt unloading plate 4, and then slide downward due to its own gravity. At this time, the staff can pick up the workpiece, thereby achieving the purpose of unloading.

[0029] In this embodiment, two groups of layer changing mechanisms 5 are provided, and the two groups of layer changing mechanisms 5 are respectively located on both sides of the first conveyor mesh belt 3. The layer changing mechanisms 5 are staggered. By providing two groups of layer changing mechanisms 5, the workpieces can be conveyed from the bottom layer first conveyor mesh belt 3 to the top layer first conveyor mesh belt 3, so that a new batch of workpieces can be dried in time.

[0030] Example 2

[0031] Based on Example 1, a preferred embodiment of a multi-layer drying machine provided by the utility model is as follows: Figures 1 to 5 As shown: the layer changing mechanism 5 includes a screw rod 51, a slider 52, a transmission rod 53, a lifting plate 54 and a second conveying mesh belt 55. The surface of the dryer body 2 is rotatably connected to the screw rod 51, the surface of the screw rod 51 is threadedly connected to the slider 52, the surface of the slider 52 is rotatably connected to the transmission rod 53, the back of the transmission rod 53 is rotatably connected to the lifting plate 54, and the back of the lifting plate 54 is rotatably connected to the second conveying mesh belt 55.

[0032] In this embodiment, the two ends of the transmission rod 53 are respectively connected to the slider 52 and the lifting plate 54, and the transmission rod 53 is arranged at an angle. Since the two ends of the transmission rod 53 are respectively rotationally connected to the slider 52 and the lifting plate 54, and the transmission rod 53 is arranged at an angle, when the slider 52 slides, a thrust force is applied to the transmission rod 53, causing the transmission rod 53 to move upward, and at this time the lifting plate 54 will move upward accordingly.

[0033] In this embodiment, vertically arranged slide grooves are provided on the surface and back of the dryer body 2, and the second conveyor mesh belt 55 is embedded in the slide groove on the surface of the dryer body 2 and is slidably connected to the dryer body 2. Because the second conveyor mesh belt 55 is embedded in the slide groove on the surface of the dryer body 2 and is slidably connected to the dryer body 2, the second conveyor mesh belt 55 can be driven by the lifting plate 54 to slide upward in the vertical groove of the dryer body 2. When the second conveyor mesh belt 55 rises to be flush with the second-layer first conveyor mesh belt 3, the workpiece will be transported to the top of the second-layer first conveyor mesh belt 3, and then the workpiece will be transported to the top of the highest layer of the first conveyor mesh belt 3 through the layer changing mechanism 5 on the left, thereby achieving the purpose of layer changing. At this time, the bottom layer of the first conveyor mesh belt 3 will be vacant, and the staff can place a new batch of workpieces on it for drying, thereby achieving the purpose of simultaneous drying, thereby improving work efficiency.

[0034] The working principle and use process of the utility model are as follows: first, the dryer body 2 is started, and then the workpiece is placed on the first conveyor mesh belt 3 at the bottom layer. At this time, the first conveyor mesh belt 3 will drive the workpiece to move, so as to convey the workpiece to the second conveyor mesh belt 55 on the right side. At this time, the control motor drives the screw rod 51 to rotate clockwise, and the screw rod 51 will drive the slider 52 to slide to the left. Since the two ends of the transmission rod 53 are respectively connected to the slider 52 and the lifting plate 54 for rotation, and the transmission rod 53 is inclined, when the slider 52 slides, a thrust is applied to the transmission rod 53, so that the transmission rod 53 moves upward. At this time, the lifting plate 54 will move upward and drive the second conveyor mesh belt 55 to slide upward in the vertical groove of the dryer body 2. When the second conveyor mesh belt 55 rises to the same level as the second-layer first conveyor mesh belt 3, the workpiece will be conveyed to the top of the second-layer first conveyor mesh belt 3, and then the workpiece will be conveyed to the top of the first conveyor mesh belt 3 on the highest layer through the layer-changing mechanism 5 on the left, thereby achieving the purpose of layer-changing. At this time, the first conveyor mesh belt 3 on the bottom layer will be vacant, and the staff can place a new batch of workpieces on it for drying, thereby achieving the purpose of simultaneous drying and improving work efficiency.

[0035] By setting up the unloading plate 4, because the unloading plate 4 is set at an angle, when the workpiece above the third layer first conveyor belt 3 is dried, it will be conveyed to the top of the unloading plate 4, and then slide downward due to its own gravity. At this time, the staff can pick up the workpiece to achieve the purpose of unloading.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
