[0002] An automatic quantitative feeding device is a mechanical device that continuously weighs, measures, and quantitatively conveys solid bulk materials (lumps, granules, powders, etc.). However, during the conveying of powdered materials, due to the inherent characteristics of powdered materials—poor flowability and strong adhesion—bridges easily occur within the feeding chamber, making it difficult for traditional feeding devices to meet the requirements of continuous, stable, and automatic feeding. This not only affects production efficiency but may also lead to material waste and equipment failure. Therefore, a new type of feeding device is urgently needed to solve these problems.

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] refer to Figure 1-3 An easily detachable automatic quantitative feeding device includes two fixed frames 1, a feeding pipe 2, a hopper 3, a discharge pipe 4, a feeding mechanism 5, and an arch-breaking mechanism 6. The two fixed frames 1 can support and fix the entire feeding device. The feeding pipe 2 passes through the two fixed frames 1 and provides a material conveying channel. The hopper 3 is located in the middle of the feeding pipe 2 and is connected to the feeding pipe 2. It can store the material to be conveyed, which is convenient for subsequent material conveying. The discharge pipe 4 is located at the bottom of one side of the feeding pipe 2 and is used to discharge the material from the feeding device. The feeding mechanism 5 is connected to the feeding pipe 2 and can convey the material in the feeding pipe 2 from the hopper 3 to the discharge pipe 4. The arch-breaking mechanism 6 is connected to the hopper 3 and can break the powder bridging in the hopper 3. It works with the feeding mechanism 5 to prevent the phenomenon of powder bridging in the feeding pipe 2, thereby ensuring that the material is smoothly discharged from the discharge pipe 4, realizing automatic, stable, and quantitative feeding of the feeding device.

[0032] In some embodiments, a back-blowing dust collection mechanism 7 is also included. The back-blowing dust collection mechanism 7 is located on one side of the feeding pipe 2 and directly above the discharge pipe 4. The discharge pipe 4 is connected to the airflow crusher and classifier. The back-blowing dust collection mechanism 7 can be welded and fixed to the feeding pipe 2 by a short section of stainless steel pipe. It can release the pressure of the material discharged from the double butterfly valve of the airflow crusher and classifier in a timely manner and collect dust to prevent dust leakage. The structure and working principle of the back-blowing dust collection mechanism 7 are existing technologies and will not be described in detail here.

[0033] In some embodiments, a material replenishment reminder component 8 is also included. The material replenishment reminder component 8 includes a fixing rod 81, a material level sensor 82, and an alarm 83. The fixing rod 81 passes through one side wall of the hopper 3. The material level sensor 82 is located inside the hopper 3 and fixed to one side of the fixing rod 81. The alarm 83 is located outside the hopper 3 and fixed to the other side of the fixing rod 81, and is electrically connected to the material level sensor 82. The material level sensor 82 senses the material height in the hopper 3. When the material in the hopper 3 is too low, the material level sensor 82 sends a signal to the alarm 83. The alarm 83 emits light and sound warning signals to remind the staff to replenish the material.

[0034] In some embodiments, the feeding mechanism 5 includes a feeding drive motor 51, two end caps 52, and a shaft-driven auger 53. The two end caps 52 are respectively sealed on both sides of the feeding pipe 2 and are detachably connected to the feeding pipe 2. The detachable connection between the end caps 52 and the feeding pipe 2 can be achieved through bolt assemblies, which facilitates the assembly and disassembly of the feeding mechanism 5 and the feeding pipe 2, thereby facilitating the cleaning of materials inside the feeding pipe 2. The shaft-driven auger 53 is driven by the two end caps 52. Bearings may be provided on the end caps 52 to enable the shaft-driven auger to drive the material. The auger 53 rotates on the two end caps 52, and one side of the auger 53 passes through the end cap 52 and is connected to the feeding drive motor 51. The feeding drive motor 51 drives the auger 53 to rotate, thereby realizing the transportation of materials from the hopper 3 to the discharge pipe 4 and finally discharging them from the discharge pipe 4. The auger 53 can be a wide-pitch single spiral auger, and the auger length of the auger 53 covers half of the opening of the discharge pipe 4. The number of rotations of the auger 53 can realize the quantitative conveying of materials.

[0035] In some embodiments, the feeding mechanism 5 further includes a feeding reducer 54, which is located between the feeding drive motor 51 and the shaft auger 53. The feeding reducer 54 can be a right-angle reducer. The feeding reducer 54 can increase the output torque applied by the feeding drive motor 51 to the shaft auger 53, ensuring that the shaft auger 53 rotates smoothly in the material.

[0036] In some embodiments, the arch-breaking mechanism 6 includes an arch-breaking motor 61, an arch-breaking shaft 62, and multiple arch-breaking rods 63. The two sides of the arch-breaking shaft 62 are rotatably connected to the two side walls of the hopper 3, allowing the arch-breaking shaft 62 to rotate in the hopper 3. It can be fixed to the hopper 3 by flanges, bearings, and bolt assemblies to achieve a detachable connection between the hopper 3 and the arch-breaking shaft 62, and simultaneously allow the arch-breaking shaft 62 to rotate within the hopper 3. One side of the arch-breaking shaft 62 penetrates the side wall of the hopper 3 and is connected to the arch-breaking motor 61. The multiple arch-breaking rods 63 are evenly spaced on the arch-breaking shaft 62. The arch-breaking motor 61 drives the arch-breaking shaft 62 to rotate, thereby causing the multiple arch-breaking rods 63 to rotate in the material, breaking up the material and destroying the powder bridging. At the same time, the rod-shaped design can reduce the intensity of the force on the arch-breaking rods 63 during the arch-breaking process, thereby preventing damage to the arch-breaking rods 63 and extending their service life. The two adjacent anti-bridging rods 63 are perpendicular to each other, and can break up materials in different directions at the same time, thereby enhancing the destructive effect on powder bridging.

[0037] In some embodiments, the arch-breaking mechanism 6 further includes an arch-breaking reducer 64, which is disposed between the arch-breaking motor 61 and the arch-breaking shaft 62. The arch-breaking reducer 64 can be a right-angle reducer. The arch-breaking reducer 64 can increase the output torque applied by the arch-breaking motor 61 to the arch-breaking shaft 62, ensuring the smooth rotation of the arch-breaking shaft 62 in the material, thereby driving the arch-breaking rod 63 to rotate, breaking the powder bridging, and ensuring the smooth discharge of the material.

[0038] In some embodiments, the arch-breaking shaft 62 is provided with a plurality of through holes at equal intervals, and a mounting hole is provided vertically on the through hole. The arch-breaking rod 63 is coaxially provided in the through hole, and a screw rod passes through the mounting hole. The screw rod is threadedly connected to the arch-breaking shaft 62, which can realize the detachable connection between the arch-breaking shaft 62 and the arch-breaking rod 63, making it convenient for the replacement and maintenance of the arch-breaking rod 63.

[0039] In some embodiments, all parts in contact with materials in the automatic quantitative feeding device can be made of sanitary stainless steel, ensuring the corrosion resistance and hygiene of the equipment.

[0040] The specific working principle is as follows:

[0041] After the feeding drive motor 51 starts, it drives the shaft auger 53 to rotate through the feeding reducer 54. The shaft auger 53 conveys the material from the hopper 3 to the discharge pipe 4, and finally discharges it through the discharge pipe 4. Since the shaft auger 53 adopts a wide-pitch single spiral design and its length covers half of the discharge pipe opening, quantitative feeding can be achieved by controlling the number of rotations of the shaft auger 53.

[0042] When the feeding mechanism 5 conveys materials, the anti-bridging motor 61 starts synchronously, driving the anti-bridging shaft 62 to rotate via the anti-bridging reducer 64. Multiple anti-bridging rods 63 on the anti-bridging shaft 62 rotate accordingly, breaking up bridging in the material and ensuring smooth discharge. When the material is discharged from the discharge pipe 4, the resulting pressure is released through the back-blowing dust collection mechanism 7. Simultaneously, dust generated during the pressure relief process is collected to prevent dust leakage.

[0043] During the material conveying process, the level sensor 82 monitors the material height in the hopper 3 in real time. When the material level is too low, the level sensor 82 will transmit a signal to the alarm 83, which will issue an alarm signal to remind the staff to replenish the material in time to ensure continuous feeding.
