Description

Technical Field

[0001] The present application relates to material production equipment, in particular to an automatic material turning and circulating baking machine. Background Art

[0002] The description in this section only provides background information related to the present disclosure and does not constitute prior art. Baking is a process in the tea making process, and its purpose is to evaporate excess water in the tea leaves, promote the heating and aroma formation of the leaf contents, and facilitate storage. In the related art, the baking machine uses a multi-layer baking chain plate to move and bake the tea leaves. However, the baking time of different teas is different. When baking for a long time, the material needs to be output from the discharge port first, and then the material is transferred to the feeding conveyor belt for lifting and loading. In such a baking machine, during the cyclic baking process, the material needs to be removed from the inside of the baking box before feeding, which will cause heat loss when the material is cooled and then heated, resulting in uneven heating of the baking temperature of the material, affecting the baking quality of the material, and there is a problem of heat waste. Summary of the invention

[0003] In view of this, the present application provides an automatic material turning circulation baking machine, which can improve the baking quality of materials and reduce heat waste.

[0004] In order to achieve the above objectives, this application is implemented through the following technical solutions:

[0005] An automatic material turning circulation baking machine is characterized in that it comprises a baking box, a plurality of mobile conveying mechanisms arranged in the baking box for driving materials to turn over layer by layer from top to bottom, and a circulating feeding conveying mechanism installed in the baking box for lifting the materials outputted by the mobile conveying mechanism on the bottom layer to the mobile conveying mechanism on the top layer in the baking box; a discharging mechanism and a material guiding mechanism for selectively guiding the materials outputted by the mobile conveying mechanism on the bottom layer to the circulating feeding conveying mechanism for loading or to the discharging mechanism for discharging are also arranged in the baking box.

[0006] The above-mentioned automatic material turning and circulating baking machine of the present application can lift the material from the lowest layer of the mobile conveying mechanism to the upper layer of the mobile conveying mechanism in the baking box by arranging the material guide mechanism and the circulating material feeding and conveying mechanism in the baking box, thereby realizing the circulating baking inside the baking box. This can improve the baking quality of the material and reduce the waste of heat. And the material guide mechanism can selectively guide the material to the circulating material feeding and conveying mechanism or the material discharging mechanism, so that the baking machine can be suitable for baking needs at different times at the same time, and has better flexibility and applicability.

[0007] In some embodiments, the circulating loading and conveying mechanism and the discharging mechanism are arranged on both sides of the bottom-level movable conveying mechanism, and a bottom-level conveying component for transferring materials to the circulating loading and conveying mechanism is also arranged below the bottom-level movable conveying mechanism, and the material guiding mechanism selectively guides the materials to the bottom-level conveying component or the discharging mechanism.

[0008] In some embodiments, the material guiding mechanism includes a rotating shaft rotatably mounted in the baking box and a material guiding plate fixedly mounted on the rotating shaft, the rotating shaft is located between the output end of the lowest mobile conveying mechanism and the input end of the bottom conveying assembly, and the material guiding plate has a first state of guiding the material to the bottom conveying assembly and a second state of guiding the material to the discharging mechanism during forward and reverse rotation.

[0009] In some embodiments, the circulating feeding conveying mechanism is a conveying chain plate mechanism, and a hopper for storing materials is arranged on the chain plate of the conveying chain plate mechanism. The material output by the bottom conveying component falls into the hopper at the lower end of the circulating feeding conveying mechanism. During the movement of the circulating feeding conveying mechanism, the hopper is lifted to the top of the topmost mobile conveying mechanism and the posture of the hopper is deflected, thereby overturning the material onto the topmost mobile conveying mechanism.

[0010] In some embodiments, the circulating loading and conveying mechanism is arranged in a C shape, and the circulating loading and conveying mechanism includes a middle section located on the side of the mobile conveying mechanism, a lower arc section integrally connected to the lower end of the middle section and extending to below the output end of the bottom conveying component and bending downward, and an upper arc section integrally connected to the upper end of the middle section and extending to above the highest mobile conveying mechanism and bending upward.

[0011] In some embodiments, the hopper includes a vertical plate fixedly connected to a chain plate of a circulating feeding conveying mechanism and an upper baffle fixedly connected to an upper end of the vertical plate, and the upper baffle is inclined from bottom to top as it extends outward from the upper end of the vertical plate.

[0012] In some embodiments, the bottom conveying assembly and the movable conveying mechanism are both baking chain plates, and the discharging mechanism is a discharging conveyor belt.

[0013] In some embodiments, an air duct inlet is disposed on the baking box, and a heat recovery system in communication with the baking box is disposed above the baking box.

[0014] In some embodiments, the baking oven is further provided with an external loading conveyor belt for lifting the materials onto the mobile conveying mechanism.

By arranging a material guiding mechanism and a circulating material feeding and conveying mechanism in a baking box, the material can be lifted from the lowest layer of the mobile conveying mechanism to the upper layer of the mobile conveying mechanism in the baking box, thereby realizing circulating baking inside the baking box.

In addition, the material guiding mechanism can selectively guide the material to the circulating material feeding and conveying mechanism or the material discharging mechanism, so that the baking machine can be simultaneously applicable to baking needs at different times, and has better flexibility and applicability.

[0023] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. The terms used in the implementation method of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0024] See also Figures 1 to 5The present application provides an automatic material turning and circulating baking machine; it includes a baking box 1, a plurality of mobile conveying mechanisms 2 arranged in the baking box 1 for driving materials to roll from top to bottom layer by layer, and a circulating feeding and conveying mechanism 3 installed in the baking box 1 for lifting the materials outputted from the bottom layer of the mobile conveying mechanism 2 to the upper layer of the mobile conveying mechanism 2 in the baking box. A discharging mechanism 4 and a material guiding mechanism 5 for selectively guiding the materials outputted from the bottom layer of the mobile conveying mechanism 2 to the circulating feeding and conveying mechanism 3 for loading or to the discharging mechanism 4 for discharging are also arranged in the baking box 1. The baking object of the baking machine is mainly tea leaves, but it is not limited to tea leaves and can also be other materials, such as edible fungi, vegetables, etc. The mobile conveying mechanisms are arranged layer by layer from top to bottom. In order to allow the materials of the upper layer to fall to the mobile conveying mechanisms of the lower layer, the mobile conveying mechanisms are staggered in the left and right directions.

[0025] The automatic material turning and circulating baking machine, by arranging a material guiding mechanism 5 and a circulating material feeding and conveying mechanism 3 in the baking box 1, can lift the material from the lowest layer of the mobile conveying mechanism 2 to the upper layer of the mobile conveying mechanism 2 in the baking box 1, thereby realizing circulating baking inside the baking box 1. This can improve the baking quality of the material and reduce the waste of heat. And the material guiding mechanism 5 can selectively guide the material to the circulating material feeding and conveying mechanism 3 or the material discharging mechanism 4, so that the baking machine can be simultaneously applicable to baking needs at different times, and has better flexibility and applicability.

[0026] The circulating feeding conveying mechanism 3 and the discharging mechanism 4 are arranged on both sides of the bottommost mobile conveying mechanism 2. For example, the circulating feeding conveying mechanism 3 is located on the left side, and the discharging mechanism 4 is located on the right side. A bottom conveying assembly 6 for transferring materials to the circulating feeding conveying mechanism 3 is also arranged below the bottommost mobile conveying mechanism 2. The material guiding mechanism 5 selectively guides the materials to the bottom conveying assembly 6 or the discharging mechanism 4. The addition of the bottom conveying assembly 6 can disperse the circulating feeding conveying mechanism 3 and the discharging mechanism 4 on the left and right sides of the mobile conveying group, so that the structural distribution is more reasonable. In some embodiments, the lower end of the circulating feeding conveying mechanism 3 can also be directly extended to the side of the material guiding mechanism 5 without separately arranging the bottom conveying assembly 6.

[0027] The material guide mechanism 5 includes a rotating shaft 51 rotatably mounted in the baking box 1 and a material guide plate 52 fixedly mounted on the rotating shaft 51. The rotating shaft 51 is located between the output end of the bottom mobile conveying mechanism 2 and the input end of the bottom conveying assembly 6. The material guide 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 discharge mechanism 4 during the forward and reverse rotation process. Figure 2, wherein the guide plate 52 is in the solid line state, it is the first state mentioned above, and the guide plate 52 is in the dotted line state, it is the second state mentioned above. The drive of the rotating shaft 51 can be manually driven, or it can be automatically driven by adding an external motor.

[0028] The circulating feeding conveying mechanism 3 is a conveying chain plate mechanism, and a hopper 34 for storing materials is arranged on the chain plate 35 of the conveying chain plate mechanism. The material output by the bottom conveying component 6 falls 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 the top of the uppermost mobile conveying mechanism 2 and the posture of the hopper 34 is deflected, thereby overturning the material onto the uppermost mobile conveying mechanism 2.

[0029] The circulating feeding conveying mechanism 3 is arranged in a C shape, and comprises a middle section 31 located at the side of the mobile conveying mechanism 2, a lower arc section 32 integrally connected to the lower end of the middle section 31 and extending to the lower side of the output end of the bottom conveying assembly 6 and bending downward, and an upper arc section 33 integrally connected to the upper end of the middle section 31 and extending to the upper side of the highest mobile conveying mechanism 2 and bending upward. The material dumping of the hopper 34 occurs at the lower position of the upper arc section 33, see Figure 4 , the material is gradually poured out as the angle of the hopper 34 changes. The lower arc section 32 and the upper arc section 33 and the middle section 31 are all arc transitions, which can avoid mutual interference between the chain plates 35.

[0030] See also Figure 5 The hopper 34 includes a vertical plate 341 fixedly 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 inclined from bottom to top during the process of extending outward from the upper end of the vertical plate 341. There is a certain inclination angle between the upper baffle 342 and the vertical plate 341, preferably 45°, which is convenient for material discharge and can reduce the extension length of the upper arc section 33. In order to ensure that the material does not run out from the front and rear sides of the vertical plate 341, side baffles are preferably provided on the front and rear sides of the vertical plate 341.

[0031] The bottom conveying assembly 6 and the mobile conveying mechanism 2 are both baking chain plates, and the discharging mechanism 4 is a discharging conveyor belt. In some embodiments, the discharging mechanism 4 can be a tea outlet, a tea chute, etc. that directly guides the material out of the baking box 1.

[0032] An air duct inlet 11 is arranged on the baking box 1 , and a heat recovery system 7 in communication with the baking box 1 is arranged above the baking box 1 .

[0033] The baking box 1 is also provided with an external feeding conveyor belt 8 for lifting the materials onto the mobile conveying mechanism 2. The external feeding conveyor belt 8 is mainly used to lift the external materials into the oven.

[0034] The following briefly describes the working process and use method of the automatic material turning cycle baking machine in the above embodiment:

[0035] Take roasted tea leaves as an example, see Figure 1 The tea leaves are lifted by the external feeding conveyor belt 8 to the uppermost mobile conveying mechanism 2 in the baking box 1 for baking. The tea leaves are moved by the uppermost mobile conveying mechanism 2. When the tea leaves move to the output end, the tea leaves are turned over to the second-layer mobile conveying mechanism 2. In this way, the tea leaves roll layer by layer from top to bottom in the baking box 1, and then the tea leaves move to the output end of the lowermost mobile conveying mechanism 2. Figure 2 When the tea leaves are baked, the guide plate 52 is rotated to the dotted line state, and the tea leaves slide onto the discharging conveyor belt under the guidance of the guide plate 52, and the tea leaves are transported from the baking box 1 to the outside. Figure 2 , the guide plate 52 is rotated to the solid line state, the tea leaves are guided to the bottom conveying assembly 6, and 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 down and are caught by the hopper 34 at the lower inner layer of the circulating feeding conveying mechanism 3. The hopper 34 moves with the tea leaves to move to the lower arc section 32. Figure 4 As the posture of the hopper 34 is deflected, the material is gradually poured onto the uppermost mobile conveying mechanism 2 to continue baking.
