[0064] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0065] Example

[0066] according to Figure 1-Figure 10 ,like Figure 1 , 2 As shown in and 3, a betel nut seed roasting machine for production and processing provided by an embodiment of the present invention comprises a roasting box 1, wherein a roasting zone 11 and a cooling zone 12 are arranged inside the roasting box 1, a mounting frame 23 is fixedly connected to the outer wall of the roasting box 1, roasting racks 2 equidistantly distributed from top to bottom are arranged on the inner wall of the roasting zone 11, a conveyor belt 8 equidistantly distributed from top to bottom is fixedly installed on the inner wall of the cooling zone 12, and a driving assembly 3 is arranged between the mounting frame 23 and the roasting rack 2;

[0067] The baking rack 2 includes an upper cover 21 and a lower frame 22 that are butt-jointed with each other;

[0068] The driving assembly 3 comprises:

[0069] A rotating structure 4 for controlling the baking rack 2 to rotate on the baking area 11;

[0070] A lifting structure 5 for controlling the upper cover 21 and the lower frame 22 to separate from each other;

[0071] A conveying structure 6 for controlling the lower frame 22 to move between the baking area 11 and the cooling area 12;

[0072] A linkage structure 7 driving the rotating structure 4, the lifting structure 5 and the conveying structure 6;

[0073] The conveyor belt 8 is also provided with a heat pressing and shaping structure 9 for performing heat pressing and shaping treatment on the fruit seeds.

[0074] like Figure 8 In the embodiment, the hot pressing shaping structure 9 includes a shaping roller 91, which is rotatably connected to the inner wall of the cooling zone 12, and one end of the shaping roller 91 can be driven to rotate by an external toothed chain transmission structure; Figure 2 , Figure 3 and Figure 8 In the embodiment, a frame 81 is fixedly connected to the upper surface of the conveyor belt 8, and an inclined plate 82 is fixedly connected to the inner wall of the frame 81 near the baking area 11. The inclined plate 82 is used to limit the delivery area when the frame 81 delivers fruit seeds to the inclined plate 82 to prevent the fruit seeds from running off the track. An opening and closing plate 83 is provided on one side of the frame 81, and the opening and closing plate 83 is used to take out the fruit seeds on the conveyor belt 8;

[0075] like Figure 2 and Figure 4 In the embodiment, the rotating structure 4 comprises:

[0076] Two turntables 41 rotatably connected to the inner wall of the baking area 11;

[0077] The rotating rod 42 and the threaded screw 43 connected between the two rotating disks 41 are rotated, the rotating rod 42 is connected to the upper cover 21 through the lifting structure 5, and the threaded screw 43 is connected to the lower frame 22 through the transmission structure 6. When the rotating rod 42 rotates, the upper cover 21 can be lifted upward and separated from the lower frame 22 through the lifting structure 5, and then the threaded screw 43 can be rotated to thread the lower frame 22 to move between the baking area 11 and the cooling area 12;

[0078] The bottom support rod 44 is fixedly connected between the two rotating disks 41. The bottom support rod 44 can not only fix the rotating disk 41 and the rotating rod 42, but also connect the two rotating disks 41 under the action of the rotating rod 42 and the threaded screw 43, so as to provide stable support for the baking rack 2, and when the rotating disk 41 on one side rotates, the rotating disk 41 and the baking rack 2 on the other side can be driven to rotate synchronously;

[0079] One end of the rotating rod 42, the threaded screw rod 43 and the bottom support rod 44 are all extended to the outside of the baking oven 1 and are in transmission connection with the linkage structure 7. The rotating rod 42 and the threaded screw rod 43 are respectively controlled to rotate by the linkage structure 7, and the turntable 41 is driven to rotate by the bottom support rod 44.

[0080] A sliding sleeve 45 is fixedly connected to the turntable 41 near the cooling zone 12. The sliding sleeve 45 is sealingly and slidingly connected to the lower frame 22. When the lower frame 22 is docked with the sliding sleeve 45, the interior of the baking zone 11 can be closed, and support can be provided when the lower frame 22 moves. The interval between the sliding sleeve 45 and the lower frame 22 effectively limits the passage of a single layer of betel nuts. When the lower frame 22 moves into the baking zone 11, the fruit seeds on the inner bottom wall of the lower frame 22 are scraped flat and spread out.

[0081] like Figure 4 , Figure 5 and Figure 6 In the embodiment, the lifting structure 5 comprises: a lateral support column 52 fixedly connected to the rotating disk 41, a fixing seat 53 sleeved on the rotating rod 42 and the lateral support column 52, and transmission bevel gears 54 are arranged on the rotating rod 42 and the fixing seat 53, one of the transmission bevel gears 54 is fixedly connected to the rotating rod 42, and the other transmission bevel gear 54 is rotatably connected to the fixing seat 53, and the two transmission bevel gears 54 are meshed and connected with each other;

[0082] The internal thread sleeve 55 is rotatably connected to the fixing seat 53;

[0083] Two transmission gear discs 56 are installed under the fixed seat 53, one of which is coaxially fixedly connected to the transmission bevel gear 54 on the fixed seat 53, and the other transmission gear disc 56 is fixedly sleeved on the outer wall of the internal thread sleeve 55, and the two transmission gear discs 56 are meshed and connected with each other;

[0084] The externally threaded rod 57 is threadedly sleeved inside the internally threaded sleeve 55, and the bottom end of the externally threaded rod 57 is fixedly connected to the outer wall of the upper cover 21. When the rotating rod 42 rotates, the transmission bevel gear 54 is driven to rotate, and the transmission bevel gear 54 on the rotating rod 42 drives the transmission bevel gear 54 on the fixed seat 53 to rotate, and the transmission toothed disc 56 coaxially mounted with the transmission bevel gear 54 on the fixed seat 53 rotates, thereby driving another transmission toothed disc 56 meshing with this transmission toothed disc 56 to rotate, thereby driving the internally threaded sleeve 55 to rotate, so that the externally threaded rod 57 on the threaded upper cover 21 moves, and can drive the upper cover 21 and the lower frame 22 to separate and merge;

[0085] The upper surface and the bottom of the fixing seat 53 are both fixedly connected with an isolation cover 51 , which provides external protection for the transmission bevel gear 54 , the internal thread sleeve 55 and the transmission gear disc 56 inside the isolation cover 51 .

[0086] like Figure 4 and Figure 7 In the embodiment, the transmission structure 6 comprises:

[0087] A threaded transmission sleeve 61 threadably sleeved on the threaded screw 43;

[0088] A slide cylinder 62 slidably sleeved on the bottom support rod 44, wherein the threaded transmission sleeve 61 and the slide cylinder 62 are both fixedly connected to the lower frame 22;

[0089] like Figure 2 , Figure 3 , Figure 8 and Fig. 9 In the embodiment, the support plate 68 is fixedly connected between two adjacent conveyor belts 8, such as Figure 8 In the middle, a gap is left between the support plate 68 and the conveyor belt 8 for a single layer of betel nut seeds to pass through. When the conveyor belt 8 carries the seeds through, the upper layer of seeds is intercepted and the single layer of seeds is allowed to pass through, and the single layer of seeds is spread flat on the upper layer of the conveyor belt 8, which is conducive to cooling;

[0090] The docking triangle plate 63 is rotatably connected to the support plate 68, and the bottom of the docking triangle plate 63 is slidably connected to the support plate 68. Two docking columns 64 of the same height are fixedly connected to the outer wall of the docking triangle plate 63. The docking columns 64 are used to provide support for the bottom of the lower frame 22 when the lower frame 22 moves into the cooling zone 12 under the transmission action of the conveying structure 6, so that the lower frame 22 remains stable when it rotates and tilts. When the linkage structure 7 drives the threaded screw 43 to rotate, the threaded feed threaded transmission sleeve 61 moves, and at the same time, the slide 62 fixed to the lower frame 22 moves on the bottom support rod 44. The movement of the lower frame 22 is also restricted by the sliding sleeve 45, so that when the threaded screw 43 rotates, the threaded feed lower frame 22 can move between the baking zone 11 and the cooling zone 12, and move between the two conveyor belts 8 in the cooling zone 12. When moving between the two, the bottom of the lower frame 22 maintains a sliding connection with the docking column 64, and when the turntable 41 drives the lower frame 22 to rotate, the docking triangle plate 63 is driven to rotate on the support plate 68 through the docking column 64. After the lower frame 22 is separated from the docking column 64, the docking column 64 is kept at the bottom position under the action of the center of gravity of the docking triangle plate 63; a slide rail 69 is fixedly connected to the side wall of the support plate 68, and an arc-shaped slide groove 65 is opened on the side wall of the slide rail 69. The inside of the arc-shaped slide groove 65 is slidably connected with an arc-shaped slider 66, and the arc-shaped slider 66 is fixedly connected to the docking triangle plate 63. Reset springs 67 are fixedly connected between the two ends of the arc-shaped slider 66 and the inner wall of the docking column 64. After the lower frame 22 is separated from the docking column 64, the docking column 64 is reset by the elastic action of the reset spring 67 itself, which is convenient for next use;

[0091] like Figure 3 , Figure 4 and Fig.10 In the embodiment, the linkage structure 7 comprises:

[0092] A driven gear 73 fixedly connected to the rotating disk 41, the rotating rod 42 and the threaded screw 43;

[0093] A support plate 74 mounted on one end of the rotating plate 41, the rotating rod 42 and the threaded screw 43 located outside the baking oven 1;

[0094] The driving gear sleeve 75 connected to the supporting plate 74 is rotatably connected, and the outer wall of the driving gear sleeve 75 can be driven to rotate by an external gear chain transmission structure;

[0095] A polygonal column 71 slidably sleeved on the driving gear sleeve 75;

[0096] A driving gear 72 fixedly connected to the polygonal column 71, wherein the driving gear 72 can be meshed and connected with the driven gear 73 on the rotating disk 41, the rotating rod 42, and the threaded screw 43 respectively;

[0097] The cylinder 76 fixedly connected to the mounting frame 23 has an output end fixedly connected to the polygonal column 71. The polygonal column 71 and the driving gear 72 are driven to slide in the driving gear sleeve 75 through the cylinder 76. On the basis of retaining the transmission effect of the driving gear sleeve 75 on the polygonal column 71, the position of the driving gear 72 is adjusted to mesh with the rotating rod 42, the threaded screw rod 43 and the driven gear 73 on the bottom support rod 44 respectively. When the driving gear 72 meshes with the driven gear 73 on the rotating rod 42, the rotation of the driving gear sleeve 75 can drive the rotating rod 42 to rotate. When the driving gear 72 meshes with the driven gear 73 on the threaded screw rod 43, the rotation of the driving gear sleeve 75 can drive the threaded screw rod 43 to rotate through the polygonal column 71. When the driving gear 72 meshes with the driven gear 73 on the bottom support rod 44, since the bottom support rod 44 is fixedly connected to the two rotating disks 41, the rotating disk 41 can be driven to rotate on the baking area 11, and the supporting disk 74 can be driven to rotate synchronously. Fig.10 In the embodiment, the interior of the polygonal column 71 is slidably sleeved with a limited inner rod 79, and the limited inner rod 79 is fixedly connected to the turntable 41 to assist the sliding of the polygonal column 71. A positioning rod 77 is rotatably connected to the outer wall of the polygonal column 71. One end of the positioning rod 77 passes through the side wall of the sliding connection support plate 74 and is inserted with a positioning frame 78. The positioning frame 78 is fixedly connected to the mounting frame 23. The positioning rod 77 is separated from the driven gear 73 on the bottom support rod 44. When the cylinder 76 pulls the polygonal column 71 to make the driving gear 72 engage with the driven gear 73 on the rotating rod 42 and the screw rod 43, the positioning rod 77 will be synchronously driven to insert into the positioning frame 78, so that the turntable 41 and the lower frame 22 maintain a horizontal position.

[0098] In this embodiment, fruit seeds can be put into the uppermost conveyor belt 8 through the feeding port at the top of the baking box 1. When the fruit seeds pass through the gap between the conveyor belt 8 and the support plate 68, only a single layer of fruit seeds are allowed to pass through and are put on the lower frame 22. As the lower frame 22 moves, the fruit seeds are spread on the lower frame 22. When the lower frame 22 passes through the sliding sleeve 45 on the turntable 41, the distance between the inner bottom wall of the lower frame 22 and the sliding sleeve 45 allows a single layer of betel nuts to pass through. As a result, when the lower frame 22 gradually slides into the baking area 11, the fruit seeds are spread on the lower frame 22. After one end of the lower frame 22 is sealed with the sliding sleeve 45, the rotating rod 42 is controlled to rotate, so that the upper cover 21 moves down and merges with the lower frame 22 to clamp and fix the fruit seeds. When the turntable 41 is controlled to rotate on the baking area 11, the merged upper cover 21 and the lower frame 22 are rotated inside the baking area 11, so that the fruit seeds are heated evenly during baking.

[0099] After baking to the set time, the control rod 42 is rotated to move the upper cover 21 upward and separate from the lower frame 22. The control screw rod 43 is rotated to feed the lower frame 22 in a translational manner, so that the lower frame 22 slides toward the inside of the cooling zone 12, so that the lower frame 22 enters between the two conveyor belts 8, and the bottom of the lower frame 22 is docked with the rotating structure 4 of the conveyor belt 8 to stably support the lower frame 22. The control turntable 41 is rotated to tilt one end of the lower frame 22 downward, and the fruit seeds are dumped onto the conveyor belt 8 below. The fruit seeds are cooled synchronously during the baking process. Therefore, after the pouring is completed, the turntable 41 is controlled to rotate in the opposite direction to keep the lower frame 22 horizontal. Then, the screw rod 43 is controlled to rotate to control the lower frame 22 to gradually enter the baking area 11 and reset. At the same time, the upper conveyor belt 8 gradually pours the cooled fruit seeds onto the lower frame 22. When the lower frame 22 passes through the sliding sleeve 45, the fruit seeds are spread flat on the lower frame 22, so that the lower frame 22 enters the baking area 11 again. After the upper cover 21 is controlled to reset and merge with the lower frame 22, the fruit seeds can be baked again.

[0100] In this way, the fruit seeds can be roasted and cooled in a cycle; the fruit seeds can be roasted and cooled repeatedly without stopping the machine; the lower frame 22 is shifted between the roasting area 11 and the cooling area 12 to put in the roasted fruit seeds and receive the cooled fruit seeds, and the fruit seeds can be put in continuously during a period of time, and the roasting and cooling cycle can be continuously carried out, thereby improving the production and processing efficiency of betel nut.

[0101] In this embodiment, after the roasted fruit seeds are directly placed on the conveyor belt 8, the conveyor belt 8 transmits the fruit seeds counterclockwise. When the fruit seeds pass through the gap between the support plate 68 and the conveyor belt 8, only a single layer of betel nuts are allowed to pass through. Then, the shaping roller 91 is driven by the external toothed chain transmission structure to rotate, and the fruit seeds are crushed while hot, and the fruit seeds are heat-shaped. The fruit seeds gather at one end of the surrounding frame 81. After the heat-setting process, the conveyor belt 8 is controlled to drive clockwise. After passing through the gap between the support plate 68 and the conveyor belt 8, the fruit seeds are spread on the upper layer of the conveyor belt 8 and cooled in the cooling zone 12. In the process of cyclic baking and cooling of the fruit seeds, the fruit seeds are heat-shaped for multiple times, which is not only conducive to the clamping of the fruit seeds in the lower frame 22 and the upper cover 21, but also does not need to perform subsequent heat-setting processing on the betel nuts separately, thereby simplifying the betel nut processing procedure and reducing production costs.

[0102] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
