Description

Technical Field

[0001] This utility model relates to the field of intelligent color sorting equipment, and in particular to an intelligent color sorting equipment for calcium carbonate. Background Technology

[0002] Intelligent color sorters are high-tech intelligent sorting devices that utilize photoelectric detection, image processing, machine vision, and artificial intelligence technologies based on the differences in the optical properties of materials. They identify differences in color, shape, or texture of materials using optical cameras, automatically sorting out particles of different colors, shapes, and textures. They are widely used in various industries such as grains, food, plastics, ores, and traditional Chinese medicine. Their core functions include: 1) accurately collecting and analyzing material characteristics through color CCD sensors or AI sorting models; 2) achieving efficient decision-making through intelligent algorithms, driving solenoid valves or nozzle systems to quickly separate target impurities; and 3) possessing intelligent modules such as self-checking, environmental sensing, and real-time quality inspection, enabling real-time monitoring of equipment status, adjustment of process parameters, and optimization of sorting results. Compared to traditional equipment, intelligent color sorters have significant advantages in sorting accuracy, processing efficiency, flexible production, and end-to-end collaboration, making them key equipment for the intelligent upgrading of modern agriculture and industry.

[0003] In existing technologies, to accurately remove impurities, improve product quality, increase production efficiency, and meet the stringent requirements of downstream industries for material purity and stability, intelligent color sorters are often used to screen calcium carbonate products during production. However, in actual use, the inherent characteristics of calcium carbonate and the limitations of the equipment structure often lead to clogging problems in the feeding stage of existing intelligent color sorters. Calcium carbonate has a high content of fine powder and strong hygroscopicity, making it prone to agglomeration and accumulation in the feeding hopper; irregular particle shapes can also interlock, forming mechanical blockages. Simultaneously, some intelligent color sorters have unreasonable hopper designs, with excessively small cone angles, mismatched outlet sizes, and a lack of effective anti-clogging devices, further exacerbating the risk of clogging. Once the feeding hopper is clogged, it not only interrupts production and reduces efficiency but also causes unstable material flow, affecting the accuracy of optical detection in the color sorter, resulting in false or missed impurities and reduced product quality. Furthermore, frequent clogging and cleaning increase equipment wear and maintenance costs, hindering the intelligent upgrading and economic benefits improvement of calcium carbonate production. Utility Model Content

[0004] The main objective of this invention is to provide an intelligent color sorting device for calcium carbonate, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A calcium carbonate intelligent color sorting device includes an intelligent color sorter and a feed hopper mounted on the intelligent color sorter. The feed hopper has an anti-clogging mechanism inside, which includes an eccentric disc, a drive motor, a movable plate, a connecting rod, a reciprocating plate, a clearing shaft, and a clearing rod. The eccentric disc is movably connected to the side wall of a vertical plate on the top surface of the feed hopper via a first drive shaft on its side wall. The first drive shaft is fixedly connected to the output end of the drive motor via a coupling. The movable plate is movably connected to guide rails on the side wall of the vertical plate via sliders on both sides. The connecting rod is movably connected between the movable plate and the eccentric disc. The reciprocating plate is fixedly connected to the bottom surface of the movable plate, and the clearing shaft is fixedly connected to the bottom surface of the reciprocating plate. The clearing rod is fixedly connected to the outer wall of the clearing shaft.

[0007] Preferably, a horizontal plate is fixedly installed on the top surface of the feed hopper, and a plurality of first mounting holes are opened on the top surface of the horizontal plate in a horizontal array, and a linear bearing is fixedly installed in the hole of the first mounting hole.

[0008] Preferably, the vertical plate is fixedly installed on one side of the top surface of the feed hopper, and a set of symmetrical guide rails are fixedly installed on the left side wall of the vertical plate. A motor mounting bracket is fixedly installed on the right side wall of the vertical plate, and a second mounting hole is also provided on the side wall of the vertical plate. A first rotary bearing is fixedly installed in the second mounting hole.

[0009] Preferably, a first drive shaft is fixedly installed on the right side wall of the eccentric disk, and the first drive shaft and the first rotary bearing are inserted and fixedly installed together. The drive motor is fixedly installed on the outer side wall of the motor mounting bracket, and the output end of the drive motor is fixedly installed together with the first drive shaft through a coupling.

[0010] Preferably, sliders are fixedly installed on both sides of the movable plate, and the sliders are slidably installed together with the guide rail.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the anti-clogging mechanism, used in conjunction with the intelligent color sorter, drives the eccentric disk to rotate via a drive motor and coupling. A connecting rod converts the eccentric disk's circular motion into the reciprocating motion of a movable plate along a guide rail. This, in turn, drives the reciprocating plate, unblocking shaft, and unblocking rod to continuously agitate the material in the feed hopper. This effectively breaks down blockages caused by calcium carbonate powder adhesion, damp lumps, or irregular particle aggregation, preventing blockages in the feed hopper, avoiding production interruptions, and improving efficiency. Simultaneously, reducing the frequency of blockages lowers the intensity of manual cleaning and equipment wear, reducing labor and maintenance costs, and improving economic benefits. Ultimately, this enables the intelligent color sorter to have an automatic anti-clogging function, thereby improving processing efficiency. Attached Figure Description

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 - Figure 5As shown, a calcium carbonate intelligent color sorting device includes an intelligent color sorter 1 and a feed hopper 2 installed on the intelligent color sorter 1. The feed hopper 2 is equipped with an anti-clogging mechanism 3, which includes an eccentric disc 12, a drive motor 14, a movable plate 17, a connecting rod 19, a reciprocating plate 22, a clearing shaft 23, and a clearing rod 24. The eccentric disc 12 is movably connected to the side wall of a vertical plate 7 on the top surface of the feed hopper 2 via a first transmission shaft 13 on the side wall. The first transmission shaft 13 is fixedly connected to the output end of the drive motor 14 via a coupling 15. The movable plate 17 is movably connected to the guide rail 8 on the side wall of the vertical plate 7 via sliders 18 on both sides. The connecting rod 19 is movably connected between the movable plate 17 and the eccentric disc 12. The reciprocating plate 22 is fixedly connected to the bottom surface of the movable plate 17. The clearing shaft 23 is fixedly connected to the bottom surface of the reciprocating plate 22. The clearing rod 24 is fixedly connected to the outer wall of the clearing shaft 23.

[0022] like Figure 2 As shown, a horizontal plate 4 is fixedly installed on the top surface of the feed hopper 2, and a number of first mounting holes 5 are opened in a horizontal array on the top surface of the horizontal plate 4. A linear bearing 6 is fixedly installed in the hole of the first mounting hole 5. The horizontal plate 4 is fixed to the top surface of the feed hopper 2, and the array of first mounting holes 5 on it provides mounting positions for the linear bearing 6. The linear bearing 6 and the unblocking shaft 23 are movably interlocked. When the unblocking shaft 23 moves with the reciprocating plate 22, the linear bearing 6 greatly reduces the resistance through rolling friction. This ensures the linear accuracy and stability of the unblocking shaft 23's up-and-down reciprocating motion, avoids swaying and deviation during the motion, and allows the unblocking rod 24 to accurately act on the material in the feed hopper 2.

[0023] like Figure 2 As shown, the vertical plate 7 is fixedly installed on one side of the top surface of the feed hopper 2, and a set of symmetrical guide rails 8 are fixedly installed on the left side wall of the vertical plate 7. A motor mounting bracket 9 is fixedly installed on the right side wall of the vertical plate 7, and a second mounting hole 10 is also provided on the side wall of the vertical plate 7. A first rotary bearing 11 is fixedly installed in the hole of the second mounting hole 10. The vertical plate 7 is fixed on one side of the top surface of the feed hopper 2 as a support component. The guide rail 8 on the left side wall provides sliding guidance for the movable plate 17. The motor mounting bracket 9 on the right side wall is used to install the drive motor 14. The first rotary bearing 11 in the second mounting hole 10 allows the first transmission shaft 13 to rotate flexibly, providing stable support and installation foundation for the entire anti-blocking mechanism 3. The movement guidance and installation position of each component are clearly defined. The effect is to ensure that the drive motor 14, eccentric plate 12 and other components are installed firmly, and the movable plate 17 slides smoothly along the guide rail 8, providing a reliable guarantee for subsequent transmission.

[0024] like Figure 3 and Figure 5As shown, a first drive shaft 13 is fixedly installed on the right side wall of the eccentric disk 12, and the first drive shaft 13 is inserted and fixedly installed together with the first rotary bearing 11. The drive motor 14 is fixedly installed on the outer side wall of the motor mounting bracket 9, and the output end of the drive motor 14 is fixedly installed together with the first drive shaft 13 through a coupling 15. The power output of the drive motor 14 is transmitted to the eccentric disk 12 through the coupling 15, and the rotational motion of the motor is transmitted to the eccentric disk 12. The effect is to provide a power source for the entire anti-blocking mechanism, and the eccentric structure of the eccentric disk 12 creates conditions for the subsequent conversion of circular motion into linear reciprocating motion.

[0025] like Figure 3 and Figure 4 As shown, sliders 18 are fixedly installed on both sides of the movable plate 17, and sliders 18 are slidably installed together with guide rail 8. Second drive shafts 16 are fixedly installed on the left side walls of the movable plate 17 and the eccentric disk 12, respectively. Third mounting holes 20 are opened on the upper and lower sides of the side wall of the connecting rod 19, and second rotary bearings 21 are fixedly installed in the holes of the third mounting holes 20. The second drive shaft 16 and the second rotary bearing 21 are inserted and fixedly installed together. When the eccentric disk 12 rotates, the circular motion is converted into the vertical reciprocating motion of the movable plate 17 along the guide rail 8 through the connecting rod 19. The second rotary bearing 21 ensures flexible rotation between the connecting rod 19 and the second drive shaft 16. By converting the rotational power of the eccentric disk 12 into the linear motion of the movable plate 17, a motion basis is provided for subsequent material unblocking, and the motion is stable and reliable.

[0026] like Figure 3 As shown, the reciprocating plate 22 is fixedly installed on the bottom surface of the movable plate 17, and several unblocking shafts 23 are fixedly installed on the bottom surface of the reciprocating plate 22. The unblocking shafts 23 are movably interlocked with the linear bearing 6. Several unblocking rods 24 are also fixedly installed on the outer wall of the unblocking shafts 23. The linear reciprocating motion of the movable plate 17 is transmitted to the reciprocating plate 22, which in turn causes the unblocking shafts 23 to perform linear reciprocating motion within the linear bearing 6, driving the unblocking rods 24 to agitate and unblock the material in the feed hopper 2. This can continuously break up the agglomeration and hollow structure of the material, prevent the calcium carbonate material from clogging in the feed hopper 2, and ensure smooth material conveying.

[0027] The specific operating principle of the anti-clogging mechanism 3 in conjunction with the intelligent color sorter 1 is as follows:

[0028] When calcium carbonate material becomes clogged inside the feed hopper 2, the drive motor 14, mounted on the outer wall of the motor mounting bracket 9, is activated. After power-on, the drive motor 14 rotates its output end. The output end of the drive motor 14, via the coupling 15, drives the first transmission shaft 13 on the eccentric disc 12 to rotate within the first rotary bearing 11 installed in the second mounting hole 10 on the side wall of the vertical plate 7. The first transmission shaft 13 drives the eccentric disc 12 to rotate. At this time, because the second transmission shaft 16 on the eccentric disc 12 and the movable plate 17 are respectively inserted into the second rotary bearing 21 installed in the third mounting hole 20 on the side wall of the connecting rod 19, the second transmission shaft 16 rotates within the second rotary bearing 21, causing the connecting rod 19 to swing under the rotation of the eccentric disc 12. During this swinging motion, the movable plate 17 is driven to move along the guide rail 8 installed on the side wall of the vertical plate 7 via the sliders 18 on both sides. The moving plate 17 moves up and down, and during this movement, it will simultaneously drive the reciprocating plate 22 mounted on the bottom to move up and down. At this time, the unblocking shaft 23 mounted on the bottom of the reciprocating plate 22 is inserted into the linear bearing 6 installed in the first mounting hole 5 on the top surface of the horizontal plate 4. The linear bearing 6 greatly reduces the resistance of the unblocking shaft 23 during movement through rolling friction, and at the same time provides precise linear guidance to ensure that the unblocking shaft 23 will not deviate or shake during movement, so that the unblocking shaft 23 moves vertically up and down. The unblocking rod 24 fixed on the outer wall of the unblocking shaft 23 is regularly stirred in the feed hopper 2 as the unblocking shaft 23 reciprocates. This mechanically breaks up the blockage structures such as arch bridges and rat holes formed by the agglomeration of calcium carbonate fine powder, moisture adhesion, or irregular particles hooking together, so that the material always remains in a loose and flowing state, preventing the calcium carbonate material from blocking in the feed hopper 2, and ensuring that the material is continuously and evenly fed to the intelligent color sorter 1.

[0029] When calcium carbonate material smoothly enters the intelligent color sorter 1 from the feed hopper 2, the color CCD sensor or AI sorting model inside the intelligent color sorter 1 starts to operate at high speed, acquiring images of the material and capturing optical feature information such as color, brightness, texture, and shape of each particle. This information is then transmitted to the control system of the intelligent color sorter 1 and compared and analyzed in real time with the pre-set qualified product parameters. The intelligent algorithm quickly makes a decision based on the analysis results. Once it identifies particles of different colors, shapes, or substances, it immediately triggers the corresponding solenoid valve or nozzle system. By precisely controlling the direction and intensity of the high-pressure airflow, the impurity particles are accurately separated from the material flow and fall into the waste collection area. The qualified calcium carbonate particles continue to be transported to the finished product collection area along the predetermined path, ultimately achieving efficient and high-precision screening of calcium carbonate products, effectively improving product purity and quality stability, and meeting the strict requirements of downstream industries for material quality.
