Description

Technical Field

[0001] The present invention relates to the technical field of material conveying, and in particular to a spiral conveying device for roasting green coffee beans. Background Art

[0002] In the coffee roasting industry, efficient and precise conveying of raw coffee beans plays a vital role in ensuring roasting quality and production efficiency. Screw conveyors, due to their simple structure and stable conveying, are widely used to transport raw coffee beans from storage to roasting.

[0003] Currently, common screw conveying equipment has numerous shortcomings in controlling conveying volume. Most equipment utilizes a fixed discharge port design, making it difficult to flexibly adjust the conveying volume to meet the needs of different roasting processes. For example, when roasting different varieties and batches of raw coffee beans, the optimal conveying volume required varies due to the varying characteristics of the beans, such as particle size, moisture content, and density. A fixed discharge port cannot meet diverse needs. This can lead to excessive conveying volume, causing coffee beans to accumulate and clog within the screw conveyor, impacting equipment efficiency. Alternatively, the conveying volume may be too small to meet the roasting equipment's production capacity, reducing production efficiency.

[0004] At the same time, existing screw conveyors also need improvement in terms of material transport uniformity. When raw coffee beans enter the screw conveyor from the feed port, the lack of effective guidance means the beans tend to concentrate in a single location on the screw conveyor, resulting in uneven material distribution. This not only affects the conveying efficiency of the screw conveyor but also causes uneven heating of the beans during the subsequent roasting process, seriously affecting roasting quality and leading to inconsistent coffee flavor, making it difficult to meet consumer demand for high-quality coffee.

[0005] Therefore, the present invention proposes a spiral feeding device for roasting green coffee beans to solve the above problems. Summary of the Invention

[0010] Preferably, the material discharge angle control mechanism includes a fixed cavity, which is fixedly connected to the loading chute body, and the fixed cavity is located directly below the storage plate. Electric-controlled telescopic rods are fixedly connected on both sides of the fixed cavity, and a bending positioning frame is fixedly connected to the middle of the fixed cavity. The tops of the four bending positioning frames are also fixedly connected to auxiliary bodies, and the tops of the auxiliary bodies are rotatably connected to electric-controlled swivels.

[0011] Preferably, the blanking angle control mechanism also includes a sleeve frame, which is slidably sleeved on the outer ring of the auxiliary body, and the outer ring of the sleeve frame is fixedly connected to an annular groove body, and a groove is provided on the inner side of the annular groove body. The annular groove body is fitly connected to the upper surface of the fixed cavity, and an adjusting rod is rotatably connected in the electric control rotating ring, and one end of the adjusting rod is fixedly connected to an arc guide rod, and the arc guide rod is slidably connected to the groove provided on the inner side of the annular groove body, and the end of the adjusting rod away from the arc guide rod is fixedly connected to a receiving plate.

[0012] Preferably, six sliding grooves are arranged around the center of the auxiliary cavity.

[0013] Preferably, a sliding rod is fixedly connected to the upper surface of the polygonal block, and the polygonal block is slidably connected in the slide groove through the sliding rod. There are six polygonal blocks, and the deflection telescopic rod is controlled to be extended and retracted by an external controller.

[0015] Preferably, the receiving plate is an arc-shaped surface, and the receiving plate is located directly below the discharge hole.

[0016] Compared with the prior art, the present invention provides a spiral feeding device for roasting green coffee beans, which has the following beneficial effects: 1. Through the setting of the delivery rate adjustment mechanism, under the extension and retraction action of the deflection telescopic rod, the forward and reverse rotation of the adjustment plate is controlled, thereby changing the size of the discharge hole to adjust the material delivery rate. The size of the discharge hole is adjusted in real time according to the roasting process parameters, so that the flow rate of green coffee beans entering the material conveyor is dynamically matched with the roasting requirements. For example, when the roaster enters the rapid heating stage, the adjustment mechanism automatically increases the delivery rate to improve production capacity; while in the fine roasting stage, the flow rate is reduced to ensure uniform heating, thereby achieving an optimal balance between energy consumption and efficiency in the overall process, ensuring that each batch of coffee beans can obtain the appropriate heating time and temperature during roasting, thereby ensuring the stability of the taste and quality of the roasted coffee, and avoiding over-burning or under-roasting. Furthermore, according to the specific characteristics of the green coffee beans, the delivery rate can be flexibly adjusted, so that the equipment can adapt to various types of green coffee beans, improving the versatility and applicability of the equipment.

[0017] 2. Through the setting of the material discharge angle control mechanism, the coordinated use of the annular trough and the regulating rod, as well as the rotation of the electric control swivel, changes the inclination angle of the receiving plate, and at the same time makes the receiving plate rotate, so as to guide the flow direction of the material transported to the conveying thread rod from above. By reasonably adjusting the feeding angle, the material can be guided to enter the conveying thread rod in a specific direction and angle, so that it is more evenly distributed on the conveying thread rod, avoiding the accumulation or deflection of the material at the feeding port, ensuring the uniform transportation of the material in the material conveyor, which is conducive to improving the uniformity of subsequent baking, making the material more evenly heated during the baking process, and improving the overall quality of the subsequent finished product. Changing the falling trajectory and speed of the material can reduce the possibility of material jamming and clogging between the discharge port and the feed port. Especially for coffee beans with uneven particle size, irregular shape or high humidity, a suitable feed angle can effectively improve the smoothness of material transportation, reduce the probability of equipment shutdown due to blockage, ensure production continuity, and improve equipment operation efficiency. When the feed angle is appropriate, the coffee beans can enter the conveying thread rod more smoothly, reducing the impact and friction on the internal components of the conveying thread rod, thereby reducing the wear of the equipment, extending the service life of the equipment, reducing the maintenance cost and replacement frequency of the equipment, and improving the stability and reliability of the equipment.

[0018] 3. With the coordinated use of the delivery volume adjustment mechanism and the material discharge angle control mechanism, the delivery volume adjustment mechanism preliminarily sets the flow rate of materials entering the material conveyor based on the requirements of the roasting process. The material discharge angle control mechanism, on this basis, performs secondary fine-tuning of the material falling speed and flow rate by changing the angle. The delivery volume adjustment mechanism controls the overall material flow rate, and the material discharge angle control mechanism guides it to fall into the delivery screw rod at the optimal angle and direction to avoid material accumulation or blockage near the feed port. The two work together to make the entire process of material from the feed chute through the delivery volume adjustment mechanism to the delivery screw rod smoother, greatly improving the material transportation efficiency per unit time and increasing production output. Stable material transportation ensures the stability of the roasting environment, which is beneficial for roasters to accurately control the roasting curve, produce coffee products with stable flavor and high quality, and enhance brand reputation.

[0022] The present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0024] The conveying volume adjustment mechanism 2 is used to adjust the material conveying volume according to demand and the state of the material when the raw coffee beans enter the conveying threaded rod 13 for conveying. The conveying volume adjustment mechanism 2 includes a placement plate 21, which is fixedly connected to the bottom of the loading chute 11. A cover plate 22 is fixedly connected to the middle of the placement plate 21. A discharge hole 23 is provided in the middle of the cover plate 22.

The auxiliary block on one side of the adjustment plate 27 is fixedly connected to a deflection telescopic rod 29.

The end of the deflection telescopic rod 29 away from the adjustment plate 27 is rotatably connected to the bottom of the storage plate 21. The deflection telescopic rod 29 is controlled by an external controller to retract and retract. The discharge hole 23 is also opened in the middle of the auxiliary cavity 24 and the adjustment plate 27.

[0026] Further examples: Please refer to Figures 6 and 7 As shown: The unloading angle control mechanism 3 is used to provide unloading angle control for materials according to the conveying amount. The unloading angle control mechanism 3 includes a fixed cavity 31, which is fixedly connected to the loading trough 11. The fixed cavity 31 is located directly below the storage plate 21. Electric telescopic rods 32 are fixedly connected on both sides of the fixed cavity 31. The electric telescopic rods 32 are mainly used to telescopically adjust the vertical position of the annular trough 37 and then adjust the inclination angle of the receiving plate 310 by changing the sliding position of the control rod 38 in the annular trough 37. The electric telescopic rods 32 are electrically connected to an external controller. A bending positioning frame 33 is fixedly connected to the middle of the fixed cavity 31. Four bending positioning frames 33 are arranged around the center of the fixed cavity 31. The tops of the four bending positioning frames 33 are also fixedly connected to auxiliary bodies 34. The tops of the auxiliary bodies 34 are rotatably connected to electric swivels 35, and the electric swivels 35 are electrically connected to the external controller.

[0027] The feeding angle control mechanism 3 also includes a sleeve frame 36, which is slidably sleeved on the outer ring of the auxiliary body 34. The outer ring of the sleeve frame 36 is fixedly connected to an annular groove body 37. A groove is provided on the inner side of the annular groove body 37. The annular groove body 37 is fitly connected to the upper surface of the fixed cavity 31. A regulating rod 38 is rotatably connected in the electric control swivel 35. One end of the regulating rod 38 is fixedly connected to an arc-shaped guide rod 39. The arc-shaped guide rod 39 is slidably connected in the groove provided on the inner side of the annular groove body 37. The end of the regulating rod 38 away from the arc-shaped guide rod 39 is fixedly connected to a receiving plate 310. The receiving plate 310 is mainly used to adjust the inclination angle to control the flow direction of the raw coffee bean material conveyed by the feeding hole 23. The receiving plate 310 is an arc-shaped surface and is located directly below the feeding hole 23.

[0028] Everything in the above example works as follows: The following is the working process of the delivery rate regulating mechanism 2 for regulating the material delivery rate according to demand and the state of the material when the green coffee beans enter the delivery threaded rod 13 for delivery: During use, the green coffee beans are stored in the feeding chute 11. When the green coffee beans are roasted, the material conveyor 1 is started, driving the conveying threaded rod 13 to rotate clockwise, and then the green coffee beans are conveyed to the roasting room. In this state, according to the state of the green coffee beans, if the conveying amount needs to be increased, the external controller drives the deflection telescopic rod 29 to retract. At this time, under the contraction action of the deflection telescopic rod 29, the adjustment plate 27 is pulled to rotate in the auxiliary cavity 24 in the opposite direction, and then the hexagonal groove 28 provided on the adjustment plate 27 rotates in the opposite direction along with the adjustment plate 27 in the auxiliary cavity 24. The reverse rotation of the hexagonal groove 28 drives the polygonal block 210 slidably connected in the hexagonal groove 28 to slide in the opposite direction along the straight groove of the hexagonal groove 28, so that the polygonal block 210 slides in the hexagonal groove 28. The rod in the hexagonal groove 28 is a fulcrum, and under the control of the slide 26 on the deflection of the polygonal blocks 210, the six polygonal blocks 210 are all deflected in the opposite direction. At this time, the end of the polygonal block 210 away from the hexagonal groove 28 is gradually deflected toward the edge of the auxiliary cavity 24. At this time, the wider the range of the discharge hole 23 is opened, the faster the green coffee beans stored above the storage plate 21 flow to the bottom under the action of gravity, and the delivery amount of green coffee beans increases. If the delivery amount needs to be reduced, the controller drives the deflection telescopic rod 29 to extend, pushing the adjustment plate 27 to rotate forward in the auxiliary cavity 24, driving the polygonal block 210 to deflect forward and approach the center of the auxiliary cavity 24, thereby reducing the flow space of the discharge hole 23. In this way, the delivery amount of green coffee beans is adjusted by controlling the flow opening size of the discharge hole 23.

[0029] By configuring the delivery rate adjustment mechanism 2, the forward and reverse rotation of the adjustment plate 27 is controlled by the extension and retraction of the deflecting telescopic rod 29, thereby changing the size of the discharge opening 23 and adjusting the material delivery rate. The size of the discharge opening 23 is adjusted in real time according to roasting process parameters such as roaster capacity and temperature profile, dynamically matching the flow rate of green coffee beans entering the material conveyor 1 with roasting requirements. For example, when the roaster enters the rapid heating phase, the adjustment mechanism automatically increases the delivery rate to increase production capacity; while during the fine roasting phase, the flow rate is reduced to ensure uniform heating, thereby achieving an optimal balance between energy consumption and efficiency in the overall process. This ensures that each batch of coffee beans receives the appropriate heating time and temperature during roasting, thereby ensuring the stability of the roasted coffee taste and quality and avoiding over-burning or under-roasting. Furthermore, the delivery rate can be flexibly adjusted according to the specific characteristics of the green coffee beans, making the equipment adaptable to various types of green coffee beans and improving the versatility and applicability of the equipment.

[0030] Please refer to the above working process Figures 1 to 5 .

[0031] The following is the working process of the material discharge angle control mechanism 3 for controlling the material discharge angle according to the conveying amount: When in use, the deflection telescopic rod 29 is controlled by an external controller to extend and retract to control the size of the discharge hole 23. When the size of the discharge hole 23 changes, if the conveying volume decreases and the feeding angle needs to be reduced synchronously, the electric-controlled telescopic rod 32 is started and extended upward. In the process of the electric-controlled telescopic rod 32 extending upward, since the electric-controlled telescopic rod 32 is fixedly connected to the annular groove body 37, the electric-controlled telescopic rod 32 extends to push the annular groove body 37 to move upward. Since the arc guide rod 39 is slidably connected in the annular groove body 37, the change in the vertical position of the annular groove body 37 drives the arc guide rod 39 slidably connected in the annular groove body 37 to deflect as the annular groove body 37 rises. Since the arc guide rod 39 and the receiving plate 310 are in parallel, and are respectively located on both sides of the regulating rod 38, the arc guide rod 39 can be adjusted by adjusting the arc guide rod 39. The deflection direction of the receiving plate 310 is controlled to control the deflection angle of the receiving plate 310. When the arc guide rod 39 gradually becomes parallel to the annular groove body 37 as it rises with the annular groove body 37, the deflection angle of the receiving plate 310 is changed synchronously, and gradually becomes parallel to the annular groove body 37. Then the built-in power supply of the auxiliary body 34 is started, driving the electric control swivel 35 to rotate slowly in the positive direction, and further driving the rotation of the control rod 38 through the electric control swivel 35 to control the synchronous rotation of the receiving plate 310. Then, when the inclination angle of the receiving plate 310 is reduced and the material conveying amount is synchronously slowed down, the material flows to the receiving plate 310 through the discharge hole 23, and under the action of the arc surface of the receiving plate 310, the circulation speed of the material is controlled to be slowed down, the horizontal speed component is increased, and the landing point of the material entering the conveying threaded rod 13 is more dispersed, avoiding the concentration of material in a certain local position.

[0032] If the conveying volume increases, the electrically controlled telescopic rod 32 contracts, driving the annular groove body 37 to move downward. At this time, when the annular groove body 37 controls the angle change of the arc guide rod 39, the inclined surface of the receiving plate 310 increases synchronously, and gradually becomes perpendicular to the annular groove body 37. The vertical velocity component of the material increases when it falls, and the horizontal velocity component decreases relatively, so that the material enters the conveying threaded rod 13 faster, and the landing point is closer to the central axis position of the conveying threaded rod 13. At this time, under the guidance of the inclined surface of the receiving plate 310, the circulation speed of the material is improved and the circulation of the material is guided, so as to avoid accumulation or agglomeration during material conveying, and is more conducive to the uniform distribution of the material on the conveying threaded rod 13.

[0033] By setting the material discharge angle control mechanism 3, the annular groove body 37 and the regulating rod 38 are used in conjunction with the rotation of the electrically controlled swivel 35, and the inclination angle of the receiving plate 310 is changed, and the receiving plate 310 is rotated at the same time, so as to guide the flow direction of the material transported from above to the conveying threaded rod 13. By reasonably adjusting the feeding angle, the material can be guided to enter the conveying threaded rod 13 in a specific direction and angle, so that it is more evenly distributed on the conveying threaded rod 13, avoiding the accumulation or deflection of the material at the feeding port, ensuring the uniform transportation of the material in the material conveyor 1, which is conducive to improving the uniformity of subsequent baking, making the material more evenly heated during the baking process, and improving the quality of the subsequent finished product. The overall quality of the material is improved, and the falling trajectory and speed of the material are changed, and the possibility of the material getting stuck or blocked between the discharge port and the feed port is reduced. Especially for coffee beans with uneven particle size, irregular shape or high humidity, a suitable feeding angle can effectively improve the smoothness of material transportation, reduce the probability of equipment shutdown due to blockage, ensure production continuity, and improve the operating efficiency of the equipment. When the feeding angle is appropriate, the coffee beans can enter the conveying threaded rod 13 more smoothly, reducing the impact and friction on the internal components of the conveying threaded rod 13, thereby reducing the wear of the equipment, extending the service life of the equipment, reducing the maintenance cost and replacement frequency of the equipment, and improving the stability and reliability of the equipment.

[0034] Furthermore, with the coordinated use of the delivery volume adjustment mechanism 2 and the material discharge angle control mechanism 3, the delivery volume adjustment mechanism 2 preliminarily sets the flow rate of the material entering the material conveyor 1 based on the requirements of the roasting process, and the material discharge angle control mechanism 3 performs secondary fine-tuning of the material falling speed and flow rate by changing the angle on this basis, and the delivery volume adjustment mechanism 2 controls the flow rate of the entire material, and the material discharge angle control mechanism 3 guides it to fall into the delivery thread rod 13 at the optimal angle and direction to avoid material accumulation or blockage near the feed port. The two work together to make the entire process of the material from the loading chute 11 through the delivery volume adjustment mechanism 2 to the delivery thread rod 13 smoother, greatly improving the material transportation efficiency per unit time and increasing production output. Stable material transportation ensures the stability of the roasting environment, which is beneficial for roasters to accurately control the roasting curve, produce coffee products with stable flavor and high quality, and enhance brand reputation.
