[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1 to 5 A coffee bean polishing and processing machine is shown, characterized in that it includes: a processing box 1, support feet 2 fixedly arranged around the bottom of the processing box 1, a feed inlet 3 arranged above the processing box 1, a discharge outlet 4 arranged below the processing box 1, a hinged door 6 movably connected to the discharge outlet 4, a support part 5 arranged on the processing box 1, an inclined sieving mechanism 7 arranged on the support part 5, a peeling mechanism 8 arranged inside the processing box 1, a flipping mechanism 9 arranged on the rear side of the processing box 1 that can drive the hinged door 6 to flip, a peeling mechanism 10 arranged below each of the support feet 2, and a partition mechanism 11 arranged on the inclined sieving mechanism 7.

[0022] In the above-described coffee bean polishing and processing machine, the user places coffee beans on the inclined screening mechanism 7 on the support part 5, allowing the inclined screening mechanism 7 to screen the coffee beans. At this time, the screened coffee beans fall into the processing chamber 1 through the discharge port 4. Simultaneously, the peeling mechanism 8 polishes and removes the silver skin of the coffee beans. After the coffee beans are processed, the flipping mechanism 9 drives the opening and closing door 6 to flip, causing the coffee beans in the processing chamber 1 to fall onto the peeling mechanism 10. At this time, the peeling mechanism 10 screens the silver skin of the coffee beans. After the inclined screening mechanism 7 finishes screening, the screened coffee beans are discharged through the partition mechanism 11. Compared with the existing technology, it can automatically polish and remove the silver skin on the surface of the coffee beans, and can also screen qualified coffee beans, removing the silver skin after peeling the coffee beans.

[0023] like Figure 4 As shown, in some embodiments of this utility model, the support part 5 includes inclined fixing plates 51 symmetrically fixed above the processing box 1. A plug-in frame 52 is fixed at the inclined end of each of the inclined fixing plates 51. A guide surface 53 is provided below each of the inclined fixing plates 51 and connected to the feed inlet 3. After the coffee beans are sieved, they are guided to the feed inlet 3 through the guide surface 53 and fall into the processing box 1. The inclined sieving mechanism 7 is set on the plug-in frame 52 of the inclined fixing plate 51.

[0024] like Figure 3 and 4 As shown, in some embodiments of this utility model, the inclined sieving mechanism 7 includes a sieving plate 71 movably inserted into the insertion frame 52. A waist-shaped groove 72 is fixed on the right side of the sieving plate 71 and passes through the insertion frame 52. A first motor 73 is fixed on the right side of the insertion frame 52. A turntable 74 is fixed at the output end of the first motor 73. An eccentric shaft 75 movably disposed in the waist-shaped groove 72 is fixed on one side of the periphery of the turntable 74. A guide plate 77 is provided on the left side of the sieving plate 71. A surrounding edge 76 is provided on the sieving plate 71. The first motor 73 drives the turntable 74 to rotate, causing the turntable 74 to drive the eccentric shaft 75 on it to rotate. At this time, the eccentric shaft 75 drives the sieving plate 71 to reciprocate along the insertion frame 52 through the waist-shaped groove 72, so that the coffee beans on the sieving plate 71 are sieving. After sieving, the partition mechanism 11 is driven to guide the sieving coffee beans to the guide plate 77 for export.

[0025] like Figure 4 and 5As shown, in some embodiments of this utility model, the peeling mechanism 8 includes a rotating shaft 81 rotatably sleeved inside the processing box 1. Multiple partitions 82 are fixed at intervals on the rotating shaft 81. Rollers 83 are connected to each partition 82. Multiple grinding blocks 84 are evenly distributed and fixed on the inner walls of the processing box 1 and the switch door 6. A second motor 85 is provided at the right end of the rotating shaft 81 and fixed to the right side of the processing box 1. When coffee beans fall, they fall onto the rollers 83. At this time, the coffee beans are separated by the partitions 82. Then, the second motor 85 drives the rotating shaft 81 to rotate, so that the rotating shaft 81 drives the rollers 83 to rotate. At this time, the coffee beans on the rollers 83 are polished and peeled on the multiple grinding blocks 84 evenly distributed and fixed on the inner walls of the processing box 1 and the switch door 6.

[0026] like Figure 3 and 4 As shown, in some embodiments of this utility model, the flipping mechanism 9 includes a hinge rod 91 movably hinged to the middle of the switch door 6. A plug seat 95 is fixedly provided on the rear side of the processing box 1. A first threaded sleeve 92 is movably plugged into the plug seat 95. The first threaded sleeve 92 and the hinge rod 91 are hinged to each other. A third motor 93 is fixedly provided on the rear side of the processing box 1. A first threaded rod 94 that can threadedly engage with the first threaded sleeve 92 is fixed at the output end of the third motor 93. The third motor 93 drives the first threaded rod 94 to rotate. This causes the first threaded rod 94 to drive the first threaded sleeve 92 to move along the plug seat 92. At this time, the first threaded sleeve 92 drives the hinge rod 91 to move. When the hinge rod 91 moves, it causes the switch door 6 to flip, so that coffee beans are discharged from the outlet 4.

[0027] like Figure 4 and 5 As shown, in some embodiments of this utility model, the sieve mechanism 10 includes a fixed seat 101 fixedly mounted on each of the support legs 2, a sieve filter plate 103 provided below the processing box 1, guide rods 102 that can be inserted into the fixed seats 101 at the four corners of the sieve filter plate 103, a spring 104 connected between the sieve filter plate 103 and each of the fixed seats 101, and a connecting plate 105 fixedly connected between two of the support legs 2, with a fixed section in the middle of the connecting plate 105. A fourth motor 106 is provided, and a rotating disk 107 is fixed at the output end of the fourth motor 106 and through the connecting plate 105. A protrusion 108 is fixed on one side of the periphery of the rotating disk 107. The fourth motor 106 drives the rotating disk 107 to rotate, so that the rotating disk 107 drives the protruding part of the sieve filter plate 103 to move through the protrusion 108. This causes the sieve filter plate 103 to vibrate on the fixed base 101 through the spring 104 and the guide rod 102, thereby sieving out the silver skin from the coffee beans symmetrically.

[0028] like Figure 4 and 5 As shown, in some embodiments of this utility model, the partition mechanism 11 includes a through groove 111 provided on the guide plate 77, a blocking plate 112 movably inserted into the through groove 111, a fixing frame 113 fixedly provided below the blocking plate 112, a second threaded sleeve 114 provided on the fixing frame 113, a fifth motor 115 fixedly provided below the guide plate 77, and a second threaded rod 116 that can be threadedly engaged with the second threaded sleeve 114 fixed at the output end of the fifth motor 115. The fifth motor 115 drives the second threaded rod 116 to rotate, so that the second threaded rod 116 drives the fixing frame 113 to move through the second threaded sleeve 114, so that the fixing frame 113 drives the blocking plate 112 to move until the blocking plate 112 and the guide plate 77 are level, so that the coffee beans can be discharged.
