DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the application clearer, the application will be further described in detail below with reference to the drawings. The terms used in the embodiment part of the application are only used for explaining the specific embodiments of the application, and are not intended to limit the application.

[0024] Reference Figures 1 to 5 ​The application provides an automatic material-turning and circulating baking machine. The baking machine comprises a baking box 1, a plurality of moving conveying mechanisms 2 arranged in the baking box 1 and used for turning and rolling the material layer by layer from top to bottom, a circulating material feeding conveying mechanism 3 installed in the baking box 1 and used for feeding the material output by the lowermost moving conveying mechanism 2 to the upper moving conveying mechanism 2, a material discharging mechanism 4 arranged in the baking box 1, and a material guiding mechanism 5 used for selectively guiding the material output by the lowermost moving conveying mechanism 2 to the circulating material feeding conveying mechanism 3 for feeding or to the material discharging mechanism 4 for discharging. The baking object of the baking machine is mainly tea, but it is not limited to tea and can also be other materials such as edible fungi and vegetables. The moving conveying mechanisms are arranged layer by layer from top to bottom, and the moving conveying mechanisms are arranged in staggered manner in the left-right direction so that the material of the upper layer can fall to the lower moving conveying mechanism.

[0025] The automatic material-turning and circulating baking machine can feed the material from the lowermost moving conveying mechanism 2 to the upper moving conveying mechanism 2 in the baking box 1 by arranging the material guiding mechanism 5 and the circulating material feeding conveying mechanism 3, thereby realizing the internal circulation baking of the baking box 1. In this way, the baking quality of the material can be improved, and the waste of heat can be reduced. The material guiding mechanism 5 can selectively guide the material to the circulating material feeding conveying mechanism 3 or the material discharging mechanism 4, so that the baking machine can be used for baking at different times, and the flexibility and applicability are better.

[0026] The circulating material feeding conveying mechanism 3 and the material discharging mechanism 4 are arranged on the left and right sides of the lowermost moving conveying mechanism 2, for example, the circulating material feeding conveying mechanism 3 is arranged on the left side, and the material discharging mechanism 4 is arranged on the right side. A bottom conveying assembly 6 is arranged below the lowermost moving conveying mechanism 2 and used for conveying the material to the circulating material feeding conveying mechanism 3. The material guiding mechanism 5 selectively guides the material to the bottom conveying assembly 6 or the material discharging mechanism 4. The bottom conveying assembly 6 can disperse the circulating material feeding conveying mechanism 3 and the material discharging mechanism 4 on the left and right sides of the moving conveying assembly, so that the structure is more reasonable. In some embodiments, the lower end of the circulating material feeding conveying mechanism 3 can directly extend to the side of the material guiding mechanism 5, and the bottom conveying assembly 6 is not arranged separately.

[0027] The material guiding mechanism 5 comprises a rotating shaft 51 rotatably arranged in the baking box 1 and a material guiding plate 52 fixedly arranged on the rotating shaft 51. The rotating shaft 51 is located between the output end of the lowermost moving conveying mechanism 2 and the input end of the bottom conveying assembly 6. The material guiding plate 52 has a first state of guiding the material to the bottom conveying assembly 6 and a second state of guiding the material to the material discharging mechanism 4 in the process of rotating forward and backward. Figure 2Wherein the guide plate 52 is in the first state when it is in solid line state, and is in the second state when it is in dashed line state. The driving of the rotating shaft 51 can be manual driving or automatic driving by adding an external motor.

[0028] The circulating feeding conveying mechanism 3 is a conveying chain plate mechanism, and the chain plate 35 of the conveying chain plate mechanism is provided with a hopper 34 for storing materials. The materials output by the bottom layer conveying assembly 6 fall into the hopper 34 at the lower end of the circulating feeding conveying mechanism 3. During the movement of the circulating feeding conveying mechanism 3, the hopper 34 is lifted to above the uppermost layer of the moving conveying mechanism 2, and the posture of the hopper 34 is deflected so as to overturn the materials to the uppermost layer of the moving conveying mechanism 2.

[0029] The circulating feeding conveying mechanism 3 is arranged in a C shape, and includes a middle section 31 located at the side of the moving conveying mechanism 2, a lower arc section 32 integrally connected with the lower end of the middle section 31 and extending downward and bending downward below the output end of the bottom layer conveying assembly 6, and an upper arc section 33 integrally connected with the upper end of the middle section 31 and extending upward and bending upward above the uppermost layer of the moving conveying mechanism 2. The material overturning of the hopper 34 occurs at the lower layer position of the upper arc section 33, as shown in Figure 4 , and the materials are gradually overturned as the angle of the hopper 34 changes. The lower arc section 32 and the upper arc section 33 are both circularly arc transitioned with the middle section 31, so as to avoid mutual interference between the chain plates 35.

[0030] As shown in Figure 5 , the hopper 34 includes a vertical plate 341 fixedly and vertically connected to the chain plate 35 of the circulating feeding conveying mechanism 3, and an upper baffle 342 fixedly connected to the upper end of the vertical plate 341. The upper baffle 342 is outwardly extended from the upper end of the vertical plate 341 and is obliquely arranged from bottom to top. The upper baffle 342 and the vertical plate 341 have a certain oblique angle, preferably 45°, which facilitates the discharge of the materials and reduces the extension length of the upper arc section 33. In order to prevent the materials from running out from the front and rear sides of the vertical plate 341, side baffles are preferably arranged on the front and rear sides of the vertical plate 341.

[0031] The bottom layer conveying assembly 6 and the moving conveying mechanism 2 are both baking chain plates, and the discharging mechanism 4 is a discharging conveying belt. In some embodiments, the discharging mechanism 4 can be a tea outlet, a tea sliding way or the like which directly guides the materials out of the baking box body 1.

[0032] The baking box body 1 is provided with an air duct air inlet 11, and a heat recovery system 7 is arranged above the baking box body 1 and communicates with the baking box body 1.

[0033] The baking box 1 is further provided with an outer feeding conveyor belt 8 for lifting materials to the moving conveying mechanism 2. The outer feeding conveyor belt 8 mainly lifts the outer materials to the oven.

[0034] The following briefly describes the working process and use method of the automatic turnover circulating baking machine of the above embodiment:

[0035] Taking baking tea leaves as an example, referring to Figure 1 , the tea leaves are lifted by the outer feeding conveyor belt 8 to the uppermost moving conveying mechanism 2 in the baking box 1 for baking. The tea leaves are moved with the uppermost moving conveying mechanism 2. When the tea leaves move to the output end, the tea leaves are turned over to the second layer of moving conveying mechanism 2. In this way, the tea leaves are rolled layer by layer from top to bottom in the baking box 1. Then, referring to Figure 2 , when the tea leaves are baked, the guide plate 52 is turned to the dotted line state, and the tea leaves are guided to slide to the discharge conveyor belt under the guide of the guide plate 52, and the tea leaves are conveyed from the baking box 1 to the outside. When the tea leaves still need to be baked, referring to Figure 2 , the guide plate 52 is turned to the solid line state, and the tea leaves are guided to the bottom conveying assembly 6. The tea leaves continue to move with the bottom conveying assembly 6. The tea leaves output from the output end of the bottom conveying assembly 6 fall and are caught by the hopper 34 at the lower end of the circulating feeding conveying mechanism 3. The hopper 34 lifts the tea leaves. When the hopper 34 moves to the lower arc segment 32, referring to Figure 4 , the posture of the hopper 34 is deflected, and the materials are gradually poured into the uppermost moving conveying mechanism 2 for continuous baking.

[0036] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the above embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments.
