[0014] The present invention has the following beneficial effects: 1. The present invention drives the first material guide cover to move horizontally toward the first motor through the rotation of the first screw, and the bean material grinding roller moves to the right along the inner wall of the arc-shaped filter plate. During the movement of the bean material grinding roller to the right, the vertical material guide channel that moves upward gradually compresses the elastic element. During this process, the first gear rotates clockwise along the fixed gear seat, and the axial moving disk that rotates synchronously with the bean material grinding roller drives the second screw to rotate. Under the thread cooperation of the second screw and the internal threaded member, the axial moving disk moves gradually toward the first motor. The inner threaded part is moved until the first blocking part and the second blocking part completely release the blocking of the V-shaped material guiding channel. At this time, one end of the V-shaped material guiding channel is just aligned with the vertical material guiding channel. The coffee beans in the vertical material guiding channel fall into the V-shaped material guiding channel and slide onto the inner wall of the arc-shaped filter plate. Subsequently, the first motor drives the first screw to rotate in the opposite direction. The rotation of the first screw drives the first material guiding cover to move horizontally in the opposite direction until the first material guiding cover returns to the initial position. In this process, the coffee beans are ground by the bean grinding roller rolling along the inner wall of the arc-shaped filter plate.

[0015] 2. The present invention enables the axially movable disk to move gradually close to the bean material grinding roller through the thread cooperation between the second screw and the internal threaded part, until the thread structure on the second screw just disengages from the internal threaded part, and as the first gear continues to rotate counterclockwise along the fixed gear seat, the bean material grinding roller moves to the left side close to the inner wall of the arc filter plate, and the bean material grinding roller moving to the left side pushes the arc filter plate to rotate counterclockwise until the outer wall of the arc filter plate abuts against the powder vibrator, and the powder vibrator vibrates the arc filter plate to achieve screening of coffee powder on the arc filter plate, and the screened refined coffee powder falls along the powder guide cover and is discharged.

[0016] When the bean material grinding roller is controlled to move to the right side and return to the initial position, the third motor is used to drive the conveying power shaft to rotate, and the bean material conveying pipe is driven to rotate inside the bean storage box under the action of the fixed frame. In this process, the coffee beans in the bean storage box enter the bean material conveying pipe along the feed opening. When the traveling gear moves to contact the arc-shaped inner gear seat, the traveling gear rolling along the arc-shaped inner gear seat drives the conveying auger to rotate. During the rotation of the conveying auger, the coffee beans at the feed opening are gradually conveyed to the discharge opening. When the discharge opening enters the inner side of the second material guide cover, the coffee beans in the bean material conveying pipe gradually fall into the second material guide cover along the discharge opening under the rotation action of the conveying auger. The coffee beans entering the second material guide cover slide along the inclined guide plate to the third material passing opening, and fall into the hollow material transfer box through the third material passing opening. Subsequently, a certain amount of coffee beans can be conveyed to the first material guide cover through the joint action of the bean material transfer mechanism and the second material guide mechanism.

[0038] A fixed shaft 402 rotatably connected to the corresponding lateral material baffle plate 307 is fixedly provided at one end of the bean material grinding roller 401 (specifically, the fixed shaft 402 is rotatably connected to the corresponding lateral material baffle plate 307 through a torsion spring), a first gear 403 is fixedly installed at the end of the fixed shaft 402, two limiting guide tubes 114 are symmetrically fixedly provided on the top of the second mounting frame 105, a vertical slide bar is slidably provided inside the limiting guide tube 114, a fixed gear seat 115 meshing with the first gear 403 is fixedly provided on the top of the vertical slide bar, and a linkage plate 308 is slidably fitted on the bottom of the fixed gear seat 115.

[0039] An axial movable disk 406 coaxial with the movable opening 310 is arranged inside the movable opening 310, and a first blocking member 407 and a second blocking member 408 are fixedly arranged on one side of the axial movable disk 406, respectively. The first blocking member 407 and the second blocking member 408 are respectively slidably matched with the corresponding axial groove 409 on the peripheral side of the bean material grinding roller 401, and a second screw 404 coaxial with the movable disk 406 is fixedly arranged on the other side of the axial movable disk 406, and the internal threaded member 309 is sleeved on the second screw 404 and the two are threadedly matched, and a positioning spring is arranged inside the bean material grinding roller 401, and the positioning spring is connected to the axial movable disk 406. In the initial state, the second screw 404 is threadedly matched with the internal threaded member 309, and the bean material grinding A V-shaped material guiding channel 405 is fixedly provided inside the roller 401, and the first blocking member 407 and the second blocking member 408 are both used for blocking the V-shaped material guiding channel 405; after the coffee beans are conveyed to the inside of the first material guiding cover 302, the coffee beans falling into the vertical material guiding channel 305 along the first material guiding cover 302 are supported by the arc-shaped blocking plate 301, and when the first motor 108 is started to drive the first screw 107 to rotate, the first material guiding cover 302 is driven to move horizontally toward the first motor 108 as the first screw 107 rotates (the first material guiding cover 302 is ensured to move horizontally smoothly under the action of the guide frame 304), and the bean material grinding roller 401 moves to the right along the inner wall of the arc-shaped filter plate 202 (such as Figure 1 As shown in the figure, the vertical guide channel 305 moves upwards during the movement of the bean material grinding roller 401 to the right and gradually compresses the elastic element 306. During this process, the first gear 403 rotates clockwise along the fixed gear seat 115, and the axial moving disk 406 that rotates synchronously with the bean material grinding roller 401 drives the second screw 404 to rotate. Under the thread cooperation between the second screw 404 and the internal threaded member 309, the axial moving disk 406 moves and gradually approaches the internal threaded member 309 until the first blocking member 407 and the second blocking member 408 are completely released. Except for blocking the V-shaped material guiding channel 405 (at this time, the positioning spring is stretched), at this time, one end of the V-shaped material guiding channel 405 is just aligned with the vertical material guiding channel 305, and the coffee beans in the vertical material guiding channel 305 fall into the V-shaped material guiding channel 405 and slide onto the inner wall of the arc-shaped filter plate 202, and then the first motor 108 drives the first screw 107 to rotate in the opposite direction, and the rotation of the first screw 107 drives the first material guiding cover 302 to move horizontally in the opposite direction until the first material guiding cover 302 returns to the initial position, that is, the bean grinding roller 401 returns to the initial position. Figure 1 In the position shown, during this process, the coffee beans are ground by the bean grinding roller 401 rolling along the inner wall of the arc-shaped filter plate 202.

[0040] After the bean material grinding roller 401 is controlled to return to the initial position, the first motor 108 continues to drive the first screw 107 to rotate, and under the action of the first screw 107, the first material guide cover 302 is driven to move horizontally away from the first motor 108 (that is, move to the left, and the fixed gear seat 115 does not move up and down). During this process, the lateral material baffle plate 307 slides along the top of the powder flow guide cover 101, and the first gear 403 rotates counterclockwise along the fixed gear seat 115. The axial moving disk 406 that rotates synchronously with the bean material grinding roller 401 drives the second screw 404 to rotate. Under the thread cooperation between the second screw 404 and the internal threaded part 309, the axial moving disk 406 moves gradually close to the bean material grinding roller 401 until the thread structure on the second screw 404 just disengages from the internal threaded part 309 (at this time, the positioning spring is compressed), and as the first gear 403 continues to rotate counterclockwise along the fixed gear seat 115 The bean material grinding roller 401 moves to the left side close to the inner wall of the arc-shaped filter material plate 202 (in this process, grinding is continued by the rolling bean material grinding roller 401). The bean material grinding roller 401 moving to the left side pushes the arc-shaped filter material plate 202 to rotate counterclockwise until the outer wall of the arc-shaped filter material plate 202 abuts against the powder vibrator 102. The powder vibrator 102 vibrates the arc-shaped filter material plate 202 to achieve screening of the coffee powder on the arc-shaped filter material plate 202. The screened refined coffee powder falls and is discharged along the powder guide cover 101. Then, the first motor 108 continues to drive the first screw 107 to rotate. As the first screw 107 rotates, it drives the first guide cover 302 to move horizontally toward the first motor 108 (under the action of the guide frame 304, the first guide cover 302 is ensured to move horizontally smoothly). The bean material grinding roller 401 moves to the right side along the inner wall of the arc-shaped filter material plate 202 (such as Figure 1 As shown), until the bean grinding roller 401 returns to the initial position again, at which time a certain amount of coffee beans is again conveyed into the first material guide cover 302, and then the coffee bean grinding operation is continued in the same control manner as above.

In this process, the coffee beans in the bean storage box 109 enter the bean material conveying pipe 705 along the feed inlet 707. When the running gear 711 moves to contact the arc-shaped inner gear seat 112, the running gear 711 rolling along the arc-shaped inner gear seat 112 drives the conveying auger 710 to rotate. During the rotation of the conveying auger 710, the coffee beans at the feed inlet 707 are gradually moved to the discharge port 708. When the discharge port 708 enters the inner side of the second material guide cover 503, the coffee beans in the bean material conveying tube 705 gradually fall into the second material guide cover 503 along the discharge port 708 under the rotation of the conveying auger 710. The coffee beans entering the second material guide cover 503 slide along the inclined guide plate 504 to the position of the third material passing port 507, and fall into the hollow material transfer box 602 through the third material passing port 507. Subsequently, a certain amount of coffee beans can be conveyed to the first material guide cover 302 through the joint action of the bean material transfer mechanism 6 and the second material guide mechanism 5.
