TECHNICAL FIELD

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

[0002] In the coffee roasting industry, efficient and accurate conveying of green coffee beans is crucial to ensure roasting quality and production efficiency. Spiral material conveying devices are widely used in the conveying process of green coffee beans from the storage link to the roasting link due to their simple structure and stable conveying.

[0003] Currently, the common spiral material conveying device has many deficiencies in conveying capacity control. Most devices use fixed discharge port design, and the conveying capacity is difficult to adjust flexibly according to different roasting process requirements. For example, when roasting different varieties and batches of green coffee beans, the optimal conveying capacity required is different due to the different particle size, humidity, density and other characteristics of coffee beans. The fixed discharge port cannot meet the diversified needs, which may cause the coffee beans to accumulate and block in the spiral conveyor, affecting the operation efficiency of the device, and may also cause the conveying capacity to be too small to meet the production capacity requirements of the roasting equipment, reducing the production efficiency.

[0004] At the same time, the existing spiral material conveying device also needs to be improved in the uniformity of material conveying. When the green coffee beans enter the spiral conveyor from the discharge port, there is a lack of effective guiding measures, and the coffee beans are easy to concentrate in a local position of the spiral conveyor, resulting in uneven distribution of materials. This not only affects the conveying efficiency of the spiral conveyor, but also causes uneven heating of coffee beans in the subsequent roasting process, seriously affecting the roasting quality, leading to unstable coffee flavor, and being difficult to meet the needs of consumers for high-quality coffee.

[0018] Compared with the prior art, the present application provides a spiral conveying device for roasting green coffee beans, which has the following advantages:

[0019] 1. By adjusting the conveying amount adjusting mechanism, the rotation of the adjusting plate is controlled and adjusted under the telescopic action of the deflection telescopic rod, thereby changing the size of the discharging hole, adjusting the conveying amount of the material, and adjusting the size of the discharging hole in real time according to the roasting process parameters, so that the flow of green coffee beans entering the material conveyor is dynamically matched with the roasting demand. For example, when the roaster enters the rapid heating stage, the conveying amount is automatically increased to improve the production capacity; and in the fine roasting stage, the flow 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 appropriate heating time and temperature during roasting, thereby ensuring the stability of the taste and quality of the roasted coffee, avoiding overcooking or undercooking, and further adjusting the conveying amount according to the specific characteristics of the green coffee beans, so that the device can adapt to various types of green coffee beans, improving the versatility and application range of the device.

[0020] 2. By adjusting the discharging angle control mechanism, the inclination angle of the receiving plate is changed under the cooperation of the annular groove body and the adjusting rod, and the receiving plate is rotated under the rotating action of the electric control rotating ring, thereby guiding the flow of the material conveyed into the conveying screw rod above, adjusting the feeding angle, guiding the material to enter the conveying screw rod in a specific direction and angle, and making the material more evenly distributed on the conveying screw rod, avoiding material accumulation or deviation at the feeding port, ensuring uniform conveying of the material in the material conveyor, and improving the uniformity of subsequent roasting, making the material more evenly heated during roasting, improving the overall quality of the finished product, and changing the falling trajectory and speed of the material, reducing the possibility of material jamming and blocking between the discharge port and the feeding port, especially for coffee beans with uneven particle size, irregular shape or high humidity. The appropriate feeding angle can effectively improve the smoothness of material conveying, reduce the probability of equipment downtime due to blockage, ensure the continuity of production, improve the operating efficiency of the equipment, and when the feeding angle is appropriate, the coffee beans can enter the conveying screw rod more smoothly, reducing the impact and friction on the internal components of the conveying screw rod, thereby reducing the degree of wear of the equipment, prolonging 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.

[0021] 3. With the combined use of the conveying volume adjustment mechanism and the feeding angle control mechanism, the conveying volume adjustment mechanism initially sets the flow rate of the material entering the material conveyor based on the requirements of the roasting process. The feeding angle control mechanism then makes a secondary fine adjustment to the material falling speed and flow rate by changing the angle. The conveying volume adjustment mechanism controls the overall material flow rate, while the feeding angle control mechanism guides it to fall into the conveying screw at the optimal angle and direction, avoiding material accumulation or blockage near the feed inlet. The two work together to make the entire process of material flowing from the feeding trough through the conveying volume adjustment mechanism and then to the conveying screw smoother, greatly improving the material conveying efficiency per unit time, increasing production output, and ensuring a stable material conveying environment. This allows roasters to accurately control the roasting curve, produce coffee products with stable flavor and superior quality, and enhance brand reputation. Attached Figure Description

[0042] The working principle of all the above embodiments is as follows:

[0043] The following is the working process of the conveying amount adjusting mechanism 2 for adjusting the conveying amount of the green coffee beans according to the requirements and the state of the material when the green coffee beans enter the conveying screw rod 13 for conveying:

[0044] In use, the green coffee beans are stored in the feeding groove body 11, and when the green coffee beans roasting work starts, the material conveying machine 1 is started to drive the conveying screw rod 13 to rotate clockwise, thereby conveying the green coffee beans into the roasting chamber. In this state, according to the state of the green coffee beans, if it is necessary to increase the conveying amount, the external controller drives the deflection telescopic rod 29 to contract, at this time, under the contraction action of the deflection telescopic rod 29, the adjusting plate 27 is pulled to rotate reversely in the auxiliary cavity 24, and then the hexagonal groove 28 provided on the adjusting plate 27 rotates reversely 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 reversely along the straight groove of the hexagonal groove 28, the rod on which the polygonal block 210 slides in the hexagonal groove 28 is used as a fulcrum, and under the control of the slide groove 26 on the deflection of the polygonal block 210, the six polygonal blocks 210 are all deflected reversely, at this time, the end of the polygonal block 210 away from the hexagonal groove 28 is gradually deflected to the edge of the auxiliary cavity 24, at this time, the larger the opening range of the blanking hole 23, the faster the green coffee beans stored above the placing plate 21 flow to the lower side under the action of gravity, at this time, the conveying amount of the green coffee beans is increased, if it is necessary to reduce the conveying amount, the controller drives the deflection telescopic rod 29 to extend, pushes the adjusting plate 27 to rotate forwardly in the auxiliary cavity 24, drives the polygonal block 210 to deflect forwardly, and approaches the center of the auxiliary cavity 24, thereby reducing the flow space of the blanking hole 23, so as to adjust the conveying amount of the green coffee beans by controlling the size of the flow port of the blanking hole 23.

[0045] By setting the conveying amount adjusting mechanism 2, the forward and reverse rotation of the adjusting plate 27 is controlled under the telescopic action of the deflection telescopic rod 29, thereby changing the size of the discharging hole 23 to adjust the conveying amount of the material. In this way, the size of the discharging hole 23 is adjusted in real time according to the roasting process parameters such as the capacity of the roasting machine and the temperature curve, so that the flow of green coffee beans entering the material conveyor 1 dynamically matches the roasting demand. For example, when the roasting machine enters the rapid heating stage, the adjusting mechanism automatically increases the conveying amount to improve the production capacity; while in the fine roasting stage, the flow is reduced to ensure uniform heating, thereby achieving the optimal balance between energy consumption and efficiency in the overall process. This ensures 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, avoiding overcooking or undercooking, and further adjusting the conveying amount according to the specific characteristics of the green coffee beans, so that the equipment can adapt to various types of green coffee beans, improving the versatility and application range of the equipment.

[0046] The above working process is described in detail in the following Figures 1 to 5 .

[0047] The following is the working process of the discharging angle control mechanism 3 for controlling the discharging angle of the material according to the conveying amount:

[0048] In use, when the size of the blanking hole 23 is changed by controlling the deflection telescopic rod 29 to extend or retract through the external controller, if the feeding angle needs to be reduced synchronously when the conveying amount is reduced, the electric control telescopic rod 32 is started to extend upward. During the upward extension of the electric control telescopic rod 32, the electric control telescopic rod 32 extends to push the annular groove body 37 to move upward because the electric control telescopic rod 32 is fixedly connected with the annular groove body 37. Since the arc-shaped guide rod 39 is slidingly connected in the annular groove body 37, the change of the vertical position of the annular groove body 37 drives the arc-shaped guide rod 39 slidingly connected in the annular groove body 37 to deflect with the upward movement of the annular groove body 37. Since the arc-shaped guide rod 39 is in parallel with the receiving plate 310 and is located on both sides of the regulating rod 38, the deflection direction of the arc-shaped guide rod 39 is adjusted to control the deflection angle of the receiving plate 310. During the upward movement of the arc-shaped guide rod 39, the deflection angle of the receiving plate 310 is changed synchronously when the arc-shaped guide rod 39 gradually becomes parallel with the annular groove body 37, and then the built-in power source of the auxiliary body 34 is started to drive the electric control rotating ring 35 to rotate forward slowly. The rotation of the electric control rotating ring 35 drives the rotation of the regulating rod 38 to control the synchronous rotation of the receiving plate 310. In this way, when the inclination angle of the receiving plate 310 is reduced and the conveying amount is reduced synchronously, the material flows through the blanking hole 23 to the receiving plate 310, and the flow speed of the material is controlled by the arc-shaped surface of the receiving plate 310, the horizontal velocity component is increased, and the falling point of the material into the conveying screw rod 13 is more dispersed to avoid the accumulation of the material in a local position.

[0049] If the conveying amount is increased, the electric control telescopic rod 32 is retracted to drive the annular groove body 37 to move downward. In this case, the inclination surface of the receiving plate 310 is increased synchronously when the angle of the arc-shaped guide rod 39 is changed by the annular groove body 37, and the vertical velocity component of the material is increased when the material falls, and the horizontal velocity component is relatively reduced, so that the material enters the conveying screw rod 13 more quickly, and the falling point is closer to the central axis position of the conveying screw rod 13. In this way, the flow speed of the material is increased and the flow of the material is guided under the guiding action of the inclination surface of the receiving plate 310, so that the accumulation or caking phenomenon of the material during conveying is avoided, and the uniform distribution of the material on the conveying screw rod 13 is more facilitated.

[0050] By setting the discharging angle control mechanism 3, the cooperation of the annular groove body 37 and the control rod 38, and the rotating action of the electric control rotating ring 35, the inclination angle of the receiving plate 310 is changed, and at the same time the receiving plate 310 is rotated, thereby guiding the flow direction of the material conveyed into the conveying screw rod 13 from above, reasonably adjusting the feeding angle, guiding the material to enter the conveying screw rod 13 in a specific direction and angle, making it more evenly distributed on the conveying screw rod 13, avoiding the accumulation or deflection of the material at the feeding port, ensuring the uniform conveying of the material in the material conveyor 1, which is beneficial to improve the uniformity of subsequent baking, make the material more evenly heated during baking, improve the overall quality of the finished product, and change the falling trajectory and speed of the material, reduce the possibility of jamming and blocking between the discharge port and the feeding port, especially for coffee beans with uneven particle size, irregular shape or high humidity. The appropriate feeding angle can effectively improve the smoothness of material conveying, reduce the probability of equipment downtime due to blockage, ensure the continuity of production, improve the operating efficiency of the equipment, when the feeding angle is appropriate, the coffee beans can enter the conveying screw rod 13 more smoothly, reducing the impact and friction on the internal components of the conveying screw rod 13, thereby reducing the degree of equipment wear and tear, prolonging the service life of the equipment, reducing maintenance costs and replacement frequency, and improving the stability and reliability of the equipment.

[0051] Further, in the cooperation of the conveying amount adjusting mechanism 2 and the discharging angle control mechanism 3, the conveying amount adjusting mechanism 2 preliminarily sets the flow of the material entering the material conveyor 1 based on the requirements of the baking process, and the discharging angle control mechanism 3 further finely adjusts the falling speed and flow of the material by changing the angle, and the conveying amount adjusting mechanism 2 controls the flow of the material, and the discharging angle control mechanism 3 guides it to fall into the conveying screw rod 13 at the best angle and direction, avoiding the accumulation or blockage of the material near the feeding port, and the cooperation of the two makes the whole process of the material from the feeding chute 11 through the conveying amount adjusting mechanism 2 to the conveying screw rod 13 more smooth, greatly improves the material conveying efficiency per unit time, increases the production output, and stable material conveying ensures the stability of the baking environment, which is beneficial to the precise control of the baking curve by the baker, and produces coffee products with stable flavor and excellent quality, improving the brand reputation.
