[0002] A coffee roaster is a device used to roast coffee beans. It changes the flavor and aroma of the coffee beans by causing a chemical reaction through heating. After roasting, the temperature of the beans is very high. In order to prevent the roasted coffee beans from being affected by the temperature and undergoing the chemical reaction after coming out of the drum, the roasted coffee beans need to be placed on a cooling plate and stirred while the hot air is removed. This will cool the coffee beans down gradually, fixing their flavor and aroma.

In addition to the natural cooling of the coffee beans, an exhaust fan can also be provided on one side of the cooling frame 4 to quickly extract the hot air generated by the coffee beans, so that the cooling frame 4 The temperature nearby is lowered, which is also conducive to increasing the cooling speed of the coffee beans. In addition, the grabbing component 7 can be used to reach deep into the accumulated coffee beans to grab a part of the coffee beans and then lift them into the air, thereby releasing the grabbing effect of the grabbing component 7 on the coffee beans, and the coffee beans fall from the air back onto the partition 5 of the cooling frame 4, thereby increasing the contact area between the coffee beans and the air to promote heat dissipation. When the coffee beans are thrown into the air, they are in full contact with the surrounding air, so that the heat can be transferred to the air more quickly, thereby accelerating the cooling process. In addition, this method can also avoid the accumulation of coffee beans in the cooling plate, reduce the possibility of local overheating or overcooling, and help maintain uniform cooling of the coffee beans. The grabbing component 7 is used multiple times to grab and release the coffee beans, which can shorten the cooling time of the coffee beans. After all the coffee beans are cooled, the cover plate 3 is opened, and the coffee beans on the partition 5 are pushed into the discharge chute 52 and then discharged through the discharge frame 2 set in the notch 41. The cylinder 6 provides support for the grabbing component 7.

[0028] See also Figure 4-Figure 7 As shown, in this embodiment, preferably, the grab assembly 7 includes a fixed plate 71, a moving rod 72 is movably provided at the center of the fixed plate 71, a fixed block 73 is fixedly provided on the side of the moving rod 72 away from the fixed plate 71, and rotating plates 74 are axially symmetrically provided on both sides of the fixed block 73, and a moving plate 75 is rotatably connected to the side of the rotating plate 74 away from the fixed block 73, the top of the moving plate 75 is slidably connected to the fixed plate 71, and a grab frame 76 is rotatably connected to the bottom of the moving plate 75, and a plurality of slits 77 are provided on the outer side of the grab frame 76; the grab frame 76 is initially located above the coffee beans. , the fixed plate 71 is moved downward, and the downward movement of the fixed plate 71 will drive the moving rod 72, the fixed block 73, the rotating plate 74, the moving plate 75 and the grabbing frame 76 to move downward synchronously. When the grabbing frame 76 contacts the surface of the coffee beans, the grabbing frame 76 is in a horizontal state without an inclination angle. There are multiple gaps 77 on the outside of the grabbing frame 76, so that the grabbing frame 76 can be more labor-saving and convenient to penetrate into the depth of the accumulated coffee beans after contacting the surface of the coffee beans. The gaps 77 can reduce the resistance of the grabbing frame 76 during the movement. After the grabbing frame 76 penetrates into the depth of the coffee beans, the moving rod 72 is moved upward along the fixed plate 71. The upward movement of the moving rod 72 will drive the fixed block 73 to move upward, and the upward movement of the fixed block 73 will drive the rotating plate 74 to rotate, thereby driving the moving plates 75 on both sides to move toward each other along the fixed plate 71, and the mutual approach of the moving plates 75 will drive the grabbing frames 76 to approach each other deep inside the coffee beans, and the grabbing frames 76 will also move horizontally inside the coffee beans so that more coffee beans can be grabbed into the grabbing frames 76, and then the fixed plate 71 is moved upward until the grabbing frame 76 moves above the coffee beans, and then the moving rod 72 is moved downward, and the downward movement of the moving rod 72 will drive the fixed block 73 to move downward, thereby driving the rotating plate 7 The two moving plates 75 are rotated in the opposite direction, and the two grabbing frames 76 are also moved away from each other. The coffee beans in the grabbing frames 76 move upward so that the coffee beans can fully contact with the surrounding air, so that the heat can be transferred to the air more quickly, thereby accelerating the cooling process. Since the grabbing frames 76 are movably connected to the bottom of the moving plate 75, the grabbing frames 76 can rotate relative to the moving plate 75, so that the grabbing frames 76 rotate at a certain angle to facilitate pouring out the coffee beans in the grabbing frames 76. In this way, more coffee beans can contact with the air during one grabbing process, further ensuring the cooling efficiency.

[0029] See also Figure 5 and Figure 8As shown, in this embodiment, preferably, a fixing rod 8 is movably provided through the center of the cylinder 6, the bottom of the fixing rod 8 is fixedly connected to the cooling frame 4, a first bevel gear 9 is fixedly sleeved on the outer side of the fixing rod 8, rotating rods 10 are axially symmetrically provided on both sides of the cylinder 6, a plurality of stirring rods 11 are fixedly provided on the outer side of the rotating rod 10, one end of the rotating rod 10 away from the stirring rod 11 is located in the cylinder 6 and a second bevel gear 12 is fixedly provided at the end, and the second bevel gear 12 is meshed with the first bevel gear 9 for transmission; when the roasted coffee beans are poured onto the partition 5, the motor of the cylinder 6 is started, the cylinder 6 rotates around the fixing rod 8, and the rotation of the cylinder 6 drives the rotating rod 1 0 and the stirring rod 11 rotate synchronously, and the rotation of the rotating rod 10 and the stirring rod 11 in the cooling frame 4 can stir the coffee beans, make the coffee beans loose and discharge part of the heat. Secondly, the rotating rod 10 will drive the second bevel gear 12 to rotate around the first bevel gear 9 during the rotation. The second bevel gear 12 will also rotate during the revolution, thereby driving the rotating rod 10 to rotate. The rotation of the rotating rod 10 drives the stirring rod 11 to rotate, which can further enhance the stirring effect on the coffee beans and accelerate the discharge of heat. In this step, the meshing relationship between the second bevel gear 12 and the first bevel gear 9 is used to achieve that the rotating rod 10 can also rotate during the revolution, which has a better stirring and heat dissipation effect on the coffee beans.

[0030] See also Figure 6 and Figure 7 As shown, in the present embodiment, preferably, vertical grooves 61 are axially symmetrically provided on both sides of the cylinder 6, and a moving block 13 is slidably embedded in the vertical groove 61, and a connecting rod 14 is fixedly provided on the side of the moving block 13 away from the cylinder 6, and the other end of the connecting rod 14 is fixedly connected to the fixed plate 71, and a reset spring 15 is fixedly provided between the bottom of the moving block 13 and the bottom of the vertical groove 61; when it is necessary to move the grabbing frame 76 deep into the coffee beans, the moving block 13 is moved downward along the vertical groove 61, and the downward movement of the moving block 13 will drive the connecting rod 14 and the fixed plate 71 to descend synchronously, and the reset spring 15 will be compressed in this process, and the downward movement of the fixed plate 71 will eventually drive the grabbing frame 76 to enter the coffee beans to grab the coffee beans.

[0031] See also Figure 7-Figure 10As shown, in this embodiment, preferably, a fixing frame 16 is fixedly provided at the bottom of the movable plate 75, and a movable rod 17 is rotatably provided between the fixing frames 16. Two positioning plates 18 are fixedly sleeved on the outer side of the movable rod 17, and one end of the positioning plate 18 away from the movable rod 17 is fixedly connected to the grabbing frame 76; when the grabbing frame 76 moves downward until it contacts the surface of the coffee beans, the positioning plate 18 is in a vertical downward state, and the grabbing frame 76 is also in a vertical downward state, and then the grabbing frame 76 enters the depth of the coffee beans to load a part of the coffee beans into the grabbing frame 76, and then the moving block 13 moves upward along the vertical slot 61 The movement will drive the grabbing frame 76 to move above the coffee beans. At this time, the movable rod 17 is rotated. The rotation of the movable rod 17 will drive the positioning plate 18 to rotate so that the two grabbing frames 76 rotate in directions facing each other. The rotation of the grabbing frame 76 causes the coffee beans in the grabbing frame 76 to flow out and fall back onto the partition 5 from a high place. This process allows the coffee beans to fully contact with the air. The fixed frame 16 provides support for the movable rod 17. In this step, the rotation of the movable rod 17 drives the grabbing frame 76 to rotate, which can facilitate the coffee beans in the grabbing frame 76 to roll out, so that more coffee beans can contact with the air, thereby enhancing the cooling effect.

[0032] See also Figure 9-10 As shown, in this embodiment, preferably, one end of the movable rod 17 movably passes through one side of the fixing frame 16 and a swing plate 19 is fixedly arranged at the end, and a torsion spring 20 is fixedly arranged between the two positioning plates 18 and the fixing frame 16 on one side away from each other, and the movable rod 17 is movably arranged inside the torsion spring 20; when the grabbing frame 76 moves from the depth of the coffee beans to the height and finally moves to the top of the coffee beans, it will drive the swing plate 19 to move upward together, and when the grabbing frame 76 moves to the top of the coffee beans, the swing plate 19 is rotated, and the swing plate 19 is rotated. The rotation of the torsion spring 20 will drive the movable rod 17 to rotate. During this process, the torsion spring 20 will be twisted to store energy and the grab frame 76 will rotate to pour out the coffee beans inside. When all the coffee beans in the grab frame 76 are poured out, the force applied to the swing plate 19 to make it rotate is removed. Under the force of the torsion spring 20 to restore the state, the movable rod 17, the swing plate 19 and the grab frame 76 will be driven to rotate back to the initial position, so that the grab frame 76 will return to the vertical state, which will facilitate the grab frame 76 to continue to descend to grab the coffee beans.

[0033] See also Figure 9-10As shown, in the present embodiment, preferably, a baffle rod 21 is fixedly provided axially symmetrically on the outer side of the cylinder 6, and the baffle rod 21 is movably abutted against the swing plate 19; when the grabbing frame 76 moves from the depth of the coffee beans to a higher place and finally moves to above the coffee beans, the swing plate 19 will abut against the baffle rod 21, thereby causing the swing plate 19 to rotate, and the rotation of the swing rod will eventually drive the grabbing frame 76 to rotate, thereby pouring out the coffee beans, and when all the coffee beans in the grabbing frame 76 are poured out, it will move downward again into the depth of the coffee beans, and the swing plate 19 will gradually lose the abutment of the baffle rod 21 when moving downward, and will drive the grabbing frame 76 to return to its initial state under the action of the torsion spring 20, thereby facilitating the subsequent grabbing of the coffee beans.

[0034] See also Figure 5 , Figure 7 and Fig. 9 As shown, in this embodiment, preferably, a positioning spring 22 is fixedly arranged between the fixing block 73 and the fixing plate 71, and the positioning spring 22 is movably sleeved on the outside of the moving rod 72. Limiting plates 23 are axially symmetrically arranged on both sides of the cylinder 6, and the limiting plates 23 are movably abutted against the fixing block 73; when the grabbing frame 76 moves downward, the fixing plate 71 and the fixing block 73 also move downward. When the grabbing frame 76 moves to the deep of the coffee beans, the fixing block 73 will abut against the limiting plate 23 during the descending process, so that the fixing block 7 3 moves upward, thereby driving the moving rod 72 to move upward. During this process, the positioning spring 22 will be compressed. The moving rod 72 moves upward and finally realizes that the two grabbing frames 76 move toward each other until they abut against each other, so that more coffee beans can be grabbed. Then the fixing plate 71, the fixing block 73 and the grabbing frame 76 move upward. During the upward movement of the fixing block 73, due to the loss of the abutment of the limiting plate 23, the moving rod 72 and the fixing block 73 are driven to move downward under the action of the positioning spring 22, so that the two grabbing frames 76 are away from each other.

[0035] See also Figure 7 As shown, in the present embodiment, preferably, the height of the limit plate 23 is lower than the height of the baffle 21; when the grabbing frame 76 is at the highest point, the baffle 21 is in contact with the swing plate 19, and the grabbing frame 76 is in an inclined state. Subsequently, during the downward movement of the grabbing frame 76, the swing plate 19 is first released from the contact with the baffle 21, and under the action of the torsion spring 20, the grabbing frame 76 is no longer tilted, and then continues to move downward until the grabbing frame 76 enters the coffee beans. After that, the limit plate 23 abuts against the fixed block 73, allowing the grabbing frame 76 to move laterally in the coffee beans to grab more coffee beans. Subsequently, during the upward movement of the grabbing frame 76, the limit plate 23 will first be released from the contact with the fixed block 73, allowing the two grabbing frames 76 to move away from each other, and then the swing plate 19 abuts against the baffle 21, allowing the grabbing frame 76 to rotate to pour out the coffee beans, thereby avoiding collision during the rotation of the grabbing frame 76.

[0036] See also Figure 6-Figure 8 As shown, in the present embodiment, preferably, a cylinder 24 is fixedly provided on the top of the fixed rod 8, and a curved groove 241 is provided on the outer side of the cylinder 24, and limit rods 25 are axially symmetrically provided on both sides of the curved groove 241, and the two limit rods 25 are fixedly connected to the moving blocks 13 on both sides on the side away from the curved groove 241; during the rotation of the cylinder 6 around the fixed rod 8, the limit rods 25 will be driven to rotate around the curved groove 241 provided on the cylinder 24, thereby realizing the reciprocating up and down movement of the moving blocks 13 on both sides in the vertical groove 61, and finally realizing the reciprocating up and down movement of the grabbing frame 76 to achieve the purpose of grabbing and releasing the coffee beans, because the cylinder 6 is also in a rotating state during the process of grabbing and releasing the coffee beans by the grabbing frame 76, the areas of the grabbed coffee beans are also different, which can better ensure the uniformity of the heat dissipation of the coffee beans.

[0037] The working principle of the present invention is as follows: coffee beans are roasted by using a host 1, and the roasted coffee beans are poured onto a partition 5 of a cooling frame 4. A plurality of air holes 51 are provided on the partition 5, so that the hot air emitted by the coffee beans can be discharged more quickly, thereby accelerating the cooling efficiency of the coffee beans. The motor of the cylinder 6 is started, and the cylinder 6 rotates around the fixed rod 8. The rotation of the cylinder 6 drives the rotating rod 10 and the stirring rod 11 to rotate synchronously. The rotation of the rotating rod 10 and the stirring rod 11 in the cooling frame 4 can stir the coffee beans, so that the coffee beans are loose and part of the heat can be discharged. Secondly, the rotating rod 10 will drive the second bevel gear 12 to rotate around the first bevel gear 9 during its rotation, and the second bevel gear 12 will also rotate during its revolution, thereby driving the rotating The rod 10 rotates, and the rotation of the rotating rod 10 drives the stirring rod 11 to rotate, which can further enhance the stirring effect on the coffee beans and accelerate the heat discharge. At the same time, the cylinder 6 rotates around the fixed rod 8, which drives the limiting rod 25 to rotate around the curved slide groove 241 provided on the cylinder 24, thereby realizing the reciprocating up and down movement of the moving blocks 13 on both sides in the vertical groove 61. When the grabbing frame 76 is at the highest point, the blocking rod 21 is in contact with the swing plate 19, and the grabbing frame 76 is in an inclined state. When the grabbing frame 76 moves downward, the fixed plate 71 and the fixed block 73 also move downward. When the grabbing frame 76 moves to the deep end of the coffee beans, the fixed block 73 will abut against the limiting plate 23 during the descending process, so that the fixed block 73 moves upward, thereby driving the moving rod 72 The positioning spring 22 will be compressed during this process, and the upward movement of the moving rod 72 will drive the fixed block 73 to move upward. The upward movement of the fixed block 73 will drive the rotating plate 74 to rotate, thereby driving the moving plates 75 on both sides to move toward each other along the fixed plate 71. The mutual approach of the moving plates 75 will drive the grabbing frame 76 to approach each other deep in the coffee beans, and the grabbing frame 76 will also move laterally inside the coffee beans so that more coffee beans can be grabbed into the grabbing frame 76. Subsequently, the fixed plate 71, the fixed block 73 and the grabbing frame 76 move upward. During the upward movement of the fixed block 73, due to the loss of the abutment of the limit plate 23, the moving rod 72 and the fixed block 73 will be driven to move downward under the action of the positioning spring 22, and the moving rod 72 moves downward The fixed block 73 will be driven to move downward, thereby driving the rotating plate 74 to rotate in the opposite direction, so that the two movable plates 75 move away from each other, and the two grab frames 76 also move away from each other. The coffee beans in the grab frame 76 move upward so that the coffee beans can fully contact with the surrounding air, so that the heat can be transferred to the air more quickly, thereby accelerating the cooling process. Subsequently, during the upward movement, the swing plate 19 will abut against the baffle 21, so that the swing plate 19 rotates. The rotation of the swing rod will eventually drive the grab frame 76 to rotate, thereby pouring out the coffee beans. In this process, the torsion spring 20 will twist and store energy. When all the coffee beans in the grab frame 76 are poured out, it will move downward again into the depth of the coffee beans. The swing plate 19 will gradually lose the abutment of the baffle 21 when it moves downward.Under the action of the torsion spring 20, the grabbing frame 76 will be driven to return to the initial state, so as to facilitate the subsequent grabbing of coffee beans.
