Description

Technical Field

[0001] This utility model relates to the field of color sorter technology, specifically a color sorter for screening and grading green coffee beans. Background Technology

[0002] In the coffee production and processing process, the quality of green coffee beans directly determines the flavor, aroma, and taste of the final coffee beverage, and sorting and grading are key steps to improve the uniformity of green bean quality. Currently, green coffee bean sorting and grading mainly involves separating impurities (such as stones, broken husks, and weeds), removing defective beans (such as insect-damaged beans, moldy beans, and broken beans), and grading them according to dimensions such as particle size, color depth, and density to meet the needs of different roasting processes and product positioning.

[0003] However, most existing color sorters have independently placed storage tanks. When the storage tank is nearly full, operators must pause the sorter's feeding operation, manually move the full tank from below the feeding port to a designated area, and then precisely place the empty tank directly below the feeding port. Only after this adjustment and stability can the feeding process be restarted. This manual tank replacement process is not only cumbersome but also leads to a long interruption in the feeding operation, directly affecting the continuous operating efficiency of the color sorter and increasing production time and labor costs. Therefore, we propose a color sorter for screening and grading green coffee beans. Utility Model Content

[0004] The purpose of this invention is to provide a color sorter for screening and grading green coffee beans, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions: A color sorter for screening and grading green coffee beans includes a machine body, a feeding pipe is provided inside the machine body, a rotating mechanism is rotatably connected to the bottom of the feeding pipe on the machine body, a baffle is fixedly connected to the bottom of the rotating mechanism on the machine body, a feeding port is opened in the baffle, a feeding pipe is fixedly connected to the bottom of the feeding port, and a storage tank is placed on the machine body below the feeding pipe. A switching component is provided between the machine body and the storage tank. The machine body rotates through the switching component to quickly change the storage tank. An adjustment component for extension and retraction is provided on the discharge pipe.

[0006] Preferably, the switching assembly includes a ratchet turntable rotatably connected to the machine body. Two sets of limiting rings are symmetrically fixedly connected to the top of the ratchet turntable. A storage tank is placed inside the limiting ring, and the mouth of one set of the storage tank is aligned with the discharge pipe. Two sets of rotating grooves are symmetrically opened on the machine body on both sides of the ratchet turntable. A rotating rod is rotatably connected to the rotating groove. A torsion spring is wound around the rotating rod. A pawl is fixedly connected to the top of the rotating rod. The pawl meshes with the tooth groove on the ratchet turntable. A rotating ring is fixedly connected to the outer wall of the limiting ring, and the rotating ring is coaxial with the ratchet turntable.

[0007] Preferably, the inner ring of the rotating ring has several sets of grooves at equal intervals, and the grooves are designed as arc grooves.

[0008] Preferably, the torsion spring is wound around the middle of the rotating rod, and one end of the torsion spring is fixed to the inner wall of the rotating groove by welding.

[0009] Preferably, the adjusting assembly includes a fixed frame fixedly connected to the front surface of the storage tank, a lead screw rotatably connected inside the fixed frame, a transmission block threadedly connected to the lead screw, the transmission block being linearly slidably connected to the fixed frame, a handwheel being coaxially fixedly connected to the top of the lead screw, a guide pipe being slidably connected to the discharge pipe, and the outer end of the guide pipe being fixedly connected to the outer end of the transmission block.

[0012] The beneficial effects of this utility model are: 1. This utility model uses the ratchet turntable and pawl of the switching component to quickly switch between two sets of storage tanks by simply rotating the rotating ring. Empty tanks can be connected to the discharge pipe immediately without stopping the color sorter. Compared with the traditional manual replacement method, the operation interruption time is shorter and the downtime of the equipment is effectively reduced, which significantly improves the efficiency of large-scale production. At the same time, the torsion spring provides continuous reset force for the pawl, ensuring accurate positioning after the ratchet turntable rotates and preventing the storage tank from shifting.

[0013] 2. The adjustment component of this utility model can drive the guide tube to slide and extend along the feed tube by rotating the handwheel, accurately adapting to storage tanks of different heights, ensuring that the guide tube is tightly connected to the mouth of the storage tank, effectively preventing spillage when feeding raw beans. At the same time, after the storage tank is replaced, the connection position can be quickly calibrated by adjusting the component, further simplifying the operation. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-4As shown, a color sorter for screening and grading green coffee beans includes a body 1, a feed pipe 2 inside the body 1, a rotating mechanism 3 rotatably connected to the bottom of the feed pipe 2 on the body 1, a baffle 4 fixedly connected to the bottom of the rotating mechanism 3 on the body 1, a discharge port 5 inside the baffle 4, a discharge pipe 6 fixedly connected to the bottom of the discharge port 5, a storage tank 7 placed on the body 1 below the discharge pipe 6, and a switching component 8 between the body 1 and the storage tank 7. The body 1 rotates through the switching component 8 to quickly change the storage tank 7. The discharge pipe 6 is equipped with an adjustment component 9 for extension and retraction. The switching component 8 includes... The machine includes a ratchet turntable 81 rotatably connected to the machine body 1. Two sets of limiting rings 82 are symmetrically fixedly connected to the top of the ratchet turntable 81. A storage tank 7 is placed inside the limiting ring 82. The mouth of one set of storage tanks 7 is aligned with the discharge pipe 6. Two sets of rotating grooves 83 are symmetrically opened on the machine body 1 on both sides of the ratchet turntable 81. A rotating rod 84 is rotatably connected inside the rotating groove 83. A torsion spring 85 is wound on the rotating rod 84. A pawl 86 is fixedly connected to the top of the rotating rod 84. The pawl 86 meshes with the tooth groove on the ratchet turntable 81. A rotating ring 87 is fixedly connected to the outer wall of the limiting ring 82, and the rotating ring 87 is coaxial with the ratchet turntable 81.

[0018] In operation, initially, the mouth of the storage tank 7 within a set of limiting rings 82 in the switching component 8 is precisely aligned with the feeding pipe 6. Green coffee beans enter the machine body 1 through the feeding pipe 2. After impurities are removed and graded by the rotating mechanism 3 in conjunction with the color sorting module, qualified green beans fall into the storage tank 7 through the feeding port 5 of the baffle 4 and the feeding pipe 6, achieving normal collection. When the storage tank 7 is nearly full, the operator holds the rotating ring 87 and applies rotational force. The rotating ring 87 drives the coaxial ratchet turntable 81 to rotate synchronously. The tooth grooves of the ratchet turntable 81... The pawl 86 is pushed to rotate around the rotating rod 84. At the same time, the rotating rod 84 is wound with the torsion spring 85 to store the elastic force. When the ratchet turntable 81 rotates 180°, another set of empty storage tanks 7 moves with the limiting ring 82 to directly below the feeding pipe 6. At this time, the torsion spring 85 resets and pushes the pawl 86 to re-engage into the tooth groove of the ratchet turntable 81, realizing the positioning of the ratchet turntable 81. The empty tanks are immediately connected to the feeding pipe 6. While the color sorter is continuously feeding, the operator can remove the full storage tanks 7 from the limiting ring 82 and replace them with new empty tanks, completing the seamless switching.

[0019] As a technical optimization of this utility model, the inner ring of the rotating ring 87 is provided with several sets of grooves at equal intervals, and the grooves are designed as arc grooves.

[0020] In practice, the arc-shaped groove can serve as a point of force application for the operator's hand or tool, preventing slippage when rotating the rotating ring 87. At the same time, the arc-shaped structure conforms to ergonomic design, reducing the pressure on the operator's hand when it comes into contact with the rotating ring 87, and improving operating comfort.

[0021] As a technical optimization of this utility model, a torsion spring 85 is wound around the middle of the rotating rod 84, and one end of the torsion spring 85 is fixed to the inner wall of the rotating groove 83 by welding.

[0022] In practice, welding and fixing can ensure the connection stability of one end of the torsion spring 85 and prevent it from falling off due to vibration after long-term use; the other end of the torsion spring 85 is fixedly connected to the rotating rod 84. When the rotating rod 84 rotates with the pawl 86, the torsion spring 85 can be evenly stressed and store elastic force. After the ratchet turntable 81 rotates to the designated position, the torsion spring 85 releases the elastic force to drive the rotating rod 84 and the pawl 86 to reset, ensuring that the pawl 86 is accurately engaged in the tooth groove of the ratchet turntable 81.

[0023] As a technical optimization of this utility model, the adjustment component 9 includes a fixed frame 91 fixedly connected to the front surface of the storage tank 7, a lead screw 92 rotatably connected inside the fixed frame 91, a transmission block 93 threadedly connected to the lead screw 92, the transmission block 93 being linearly slidably connected to the fixed frame 91, a handwheel 94 coaxially fixedly connected to the top of the lead screw 92, a guide pipe 95 slidably connected to the feed pipe 6, and the outer end of the guide pipe 95 being fixedly connected to the outer end of the transmission block 93.

[0024] In use, turn the handwheel 94 to rotate the lead screw 92 inside the fixed frame 91. Since the transmission block 93 is cross-shaped and slidably connected to the cross through hole of the fixed frame 91, when the lead screw 92 rotates, it drives the transmission block 93 to slide linearly along the fixed frame 91. The transmission block 93 pulls the guide tube 95 to slide along the feed tube 6 until the lower end of the guide tube 95 is close to the mouth of the storage tank 7 to prevent raw beans from spilling. The anti-slip rubber sleeve of the handwheel 94 can prevent slippage when rotating and ensure adjustment accuracy.

[0025] As a technical optimization of this utility model, the handwheel 94 is fitted with a rubber sleeve, and the outer wall of the rubber sleeve is provided with anti-slip texture.

[0026] In practice, the rubber sleeve is made of wear-resistant and elastic nitrile rubber, which can extend the service life of the handwheel 94 and buffer the impact force on the operator's hand when turning the handwheel 94. The anti-slip pattern is a uniformly distributed diagonal or diamond pattern, which can significantly increase the friction between the hand and the rubber sleeve and prevent slippage when turning the handwheel 94. It is especially suitable for scenarios where the hands are covered with coffee bean powder.

[0027] As a technical optimization of this utility model, the transmission block 93 is designed in a cross shape, and the fixed frame 91 has a cross through hole that matches the transmission block 93. One end of the transmission block 93 passes through the fixed frame 91 and is slidably connected to the fixed frame 91.

[0028] In practice, the cross-shaped design and cross-shaped through hole can strictly limit the rotational freedom of the actuator block 93, ensuring that the transmission block 93 slides only along the straight line of the fixed frame 91 under the drive of the lead screw 92, and avoids the guide tube 95 from getting stuck due to the rotation of the transmission block 93; the through-type design makes the connection between the transmission block 93 and the guide tube 95 more stable, preventing the guide tube 95 from falling off due to force when receiving green coffee beans.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
