Abstract
Description
Technical Field
[0001] This utility model belongs to the field of stone care technology, and specifically relates to an automated feeding device for stone care raw materials. Background Technology
[0002] In the field of modern architectural decoration, stone is widely used in various buildings, such as commercial buildings, hotels, and residences, for flooring and wall decoration due to its unique beauty and durability. With the increasing use of stone, the importance of stone care is becoming increasingly prominent. Stone care can effectively extend the service life of stone and maintain its beauty and functionality. In the process of stone care, the supply of raw materials is crucial.
[0003] In the process of mixing and preparing stone care raw materials, different raw materials need to be transported to the mixing equipment. However, the height of common mixing equipment varies. When a fixed feeding device faces such mixing equipment with different heights, the large height difference between the two becomes the main cause of raw material spillage. Due to the spillage, the actual amount of raw materials entering the mixing equipment deviates from the preset formula. This results in an unbalanced composition ratio of the final mixed care product, which fails to achieve the expected care effect and reduces customer satisfaction.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in the related technologies, this utility model proposes an automated feeding device for stone care materials to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to an automated feeding device for stone care materials, comprising a support frame, on which a screw feeding mechanism is rotatably mounted. The bottom end of the screw feeding mechanism is connected to a feed hopper, and the top end of the screw feeding mechanism is connected to a flexible hose. A sliding mechanism is fitted onto the screw feeding mechanism, and a lifting mechanism is provided on the support frame. The lifting mechanism is equipped with a drive mechanism to change its height. The lifting mechanism and the sliding mechanism are rotatably configured. An electromagnetic flow valve and a flow sensor are sequentially arranged from top to bottom inside the flexible hose. A controller is fixedly mounted on the support frame, and the controller is electrically connected to the screw feeding mechanism, the electromagnetic flow valve, and the flow sensor.
[0008] Furthermore, the screw feeding mechanism includes a housing, the bottom of which is rotatably mounted on the support frame. The two ends of the housing are respectively connected to the feed hopper and the hose. A drive motor is installed at the bottom of the housing. An output shaft is fixedly installed at the output end of the drive motor within the cavity of the housing. The other end of the output shaft extends to the hose.
[0009] Furthermore, a dragon blade is fixedly installed on the outer wall of the output shaft, and guide blocks are symmetrically provided on the outer wall of the housing.
[0010] Furthermore, the sliding mechanism includes a circular slider, which is sleeved on the outer wall of the housing and slidably mounted with the two guide blocks. Hinge blocks are symmetrically fixedly mounted at both ends of the circular slider.
[0011] Furthermore, the lifting mechanism includes two first hinge rods and a fixing block. The bottom ends of the two first hinge rods are rotatably mounted on the support frame, and the top ends of the two first hinge rods are rotatably mounted with connecting blocks.
[0012] Furthermore, each of the two first hinge rods is rotatably connected to a second hinge rod at its top end, and the two connecting blocks are rotatably mounted to the two second hinge rods respectively. The other ends of the two second hinge rods are rotatably mounted on the fixed block, and two connecting rods are fixedly mounted on the top of the fixed block. The two connecting rods are respectively hinged to the two hinge blocks.
[0013] Furthermore, the driving mechanism includes a bidirectional threaded screw with symmetrical and opposite threads, and the two threads on the bidirectional threaded screw are respectively threadedly installed with two connecting blocks. Anti-detachment blocks and handwheels are respectively fixedly installed at both ends of the bidirectional threaded screw.
[0014] This utility model has the following beneficial effects:
[0015] This invention allows workers to manually rotate a drive mechanism. This rotation converts the drive mechanism's own motion into a change in lateral length, which in turn converts the longitudinal length change into a lateral length change, thus achieving lifting motion. Because the lifting mechanism is rotatably connected to a sliding mechanism, and the sliding mechanism is mounted on the screw feeding mechanism, the two mechanisms are in a sliding motion relationship. Therefore, the lifting mechanism's movement drives the screw feeding mechanism to rise and fall synchronously through the sliding mechanism. During this process, the sliding mechanism slides along the screw feeding mechanism. Since the screw feeding mechanism is rotatably mounted on a support frame, as the lifting mechanism drives the screw feeding mechanism to rise and fall, the screw feeding mechanism rotates around the rotational connection point on the support frame. The hose mounted on the screw feeding mechanism also rotates accordingly. When the angle between the screw feeding mechanism and the ground increases, the hose height increases; when the angle decreases, the hose height decreases. In this way, the hose can be flexibly adjusted according to the height of the mixing equipment, effectively eliminating the height difference between the hose and the mixing equipment and fundamentally preventing raw material spillage.
[0016] This invention uses a flow sensor to monitor the flow rate of raw materials through a flexible tube in real time and transmits this data quickly and accurately to a controller. The controller then compares the received data with the preset required amount of raw materials in real time. Once the flow rate monitored by the flow sensor reaches the preset required amount, the controller immediately issues a command to close the electromagnetic flow valve and stop the rotation of some components of the screw feeding mechanism. The electromagnetic flow valve responds quickly, cutting off the flow of raw materials in the tube, thus accurately completing one feeding task. This automated control process avoids errors that may occur with manual operation, ensuring the accuracy and stability of each feeding, and providing a reliable foundation for the subsequent mixing and preparation of stone care materials.

Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0028] Please see Figures 1-5As shown, this utility model is an automated feeding device for stone care materials, including a support frame 1. A screw feeding mechanism 2 is rotatably mounted on the support frame 1. The bottom end of the screw feeding mechanism 2 is connected to a feeding bucket 3, and the top end of the screw feeding mechanism 2 is connected to a flexible hose 4. A sliding mechanism 5 is sleeved on the screw feeding mechanism 2. A lifting mechanism 6 is provided on the support frame 1. The lifting mechanism 6 is provided with a driving mechanism 7 to change its height. The lifting mechanism 6 and the sliding mechanism 5 are rotatably arranged. An electromagnetic flow valve 8 and a flow sensor 9 are arranged sequentially from top to bottom inside the flexible hose 4. A controller 10 is fixedly provided on the support frame 1. The controller 10 is electrically connected to the screw feeding mechanism 2, the electromagnetic flow valve 8, and the flow sensor 9.
[0029] Firstly, when dealing with mixing equipment of different heights, it is important to note that the drive mechanism 7 in this device is operated manually by the operator. The height of the hose 4 needs to be adjusted, and the operator manually rotates the drive mechanism 7. The rotation of the drive mechanism 7 converts its own motion, allowing the lifting mechanism 6 connected to it to convert the longitudinal length change into a lateral length change, thereby achieving lifting motion. Because the lifting mechanism 6 is rotatably connected to the sliding mechanism 5, and the sliding mechanism 5 is mounted on the screw feeding mechanism 2, the sliding mechanism 5 and the screw feeding mechanism 2 have a sliding motion relationship. Therefore, the lifting of the lifting mechanism 6 will drive the screw feeding mechanism 2 to lift synchronously through the sliding mechanism 5. During this process, the sliding mechanism 5 slides along the screw feeding mechanism 2. Since the screw feeding mechanism 2 is rotatably mounted on the support frame 1, during the lifting process of the lifting mechanism 6 driving the screw feeding mechanism 2 to lift, the screw feeding mechanism 2 will rotate around the rotational connection point on the support frame 1 as the center. As the screw feeder 2 rotates, the hose 4 installed on it also rotates. When the angle between the screw feeder 2 and the ground increases, the height of the hose 4 rises; when the angle between the screw feeder 2 and the ground decreases, the height of the hose 4 decreases (assuming the angle between the screw feeder 2 and the ground is α, then the range of α is 0° < α < 90°. It should be noted that the angle is described from the side where the lifting mechanism 6 is located). In this way, the hose 4 can be flexibly adjusted according to the height of the mixing equipment, effectively eliminating the height difference between the hose 4 and the mixing equipment, and fundamentally preventing the spillage of raw materials. It is worth noting that the hose 4 is made of a soft material. Due to its softness, the hose 4 can flexibly adapt to the positional changes of the screw feeder 2, keeping the hose 4 perpendicular to the ground. Thus, during the discharge process, the raw materials can flow down naturally by their own gravity, avoiding the inability of the raw materials to flow into the mixing equipment due to the tilt of the hose 4.
[0030] Secondly, after the position of the hose 4 is adjusted, the liquid raw material is placed into the feed tank 3. The feed tank 3 can also be connected to an external feed source to ensure that the device can continuously obtain raw materials, such as an external large-capacity liquid storage tank. This eliminates the need for frequent manual addition of raw materials and greatly improves work efficiency. Before the device starts working, the staff first sets the required amount of raw materials in the controller 10. The controller 10, as the "brain" of the entire device, controls some parts of the screw feeding mechanism 2 to rotate according to the preset instructions. The bottom end of the screw feeding mechanism 2 is connected to the feed tank 3. During its rotation, the liquid raw material in the feed tank 3 is transported upward to the hose 4 at the top.
[0031] Finally, inside the hose 4, the flow sensor 9 can monitor the flow rate of the raw material flowing through the hose 4 in real time and transmit this data quickly and accurately to the controller 10. The controller 10 then compares the received data with the preset required amount of raw material in real time. Once the flow rate monitored by the flow sensor 9 reaches the preset required amount, the controller 10 immediately issues a command to close the electromagnetic flow valve 8 and stop the rotation of some components of the screw feeding mechanism 2. The electromagnetic flow valve 8 responds quickly and cuts off the flow of raw material inside the hose 4, thereby accurately completing a feeding task. Through this automated control process, errors that may occur during manual operation are avoided, ensuring the accuracy and stability of each feeding and providing a reliable foundation for the subsequent mixing and preparation of stone care raw materials. It is important to note that the distance between the flow sensor 9 and the electromagnetic flow valve 8 inside the hose 4 is designed to be relatively close. After the controller 10 issues a command to close the electromagnetic flow valve 8 based on the feedback data from the flow sensor 9, it can minimize the extra flow caused by the inertial flow of the raw material during the time from issuing the command to the actual closure of the electromagnetic flow valve 8.
[0032] In one embodiment, the screw feeding mechanism 2 includes a housing 201, the bottom of which is rotatably mounted on the support frame 1. The two ends of the housing 201 are respectively connected to the feed hopper 3 and the hose 4. A drive motor 202 is installed at the bottom of the housing 201. An output shaft 203 is fixedly installed at the output end of the drive motor 202 and located inside the housing 201. The other end of the output shaft 203 extends to the hose 4.
[0033] The output shaft 203 is fixedly mounted with a dragon blade 204, and the outer wall of the housing 201 is symmetrically provided with guide blocks 205.
[0034] The staff first sets the required amount of raw materials in the controller 10. The controller 10 sends an operation signal to the drive motor 202 according to the preset instructions. The drive motor 202 is installed at the bottom of the housing 201, and its output end is fixedly connected to the output shaft 203 located in the inner cavity of the housing 201. When the drive motor 202 starts, it drives the output shaft 203 to rotate at high speed. The auger blades 204 fixedly installed on the outer wall of the output shaft 203 rotate synchronously. Since the bottom of the housing 201 is rotatably installed on the support frame 1, and both ends are connected to the feed tank 3 and the hose 4 respectively, the auger blades 204 can push the liquid raw materials in the feed tank 3 upward along the inner wall of the housing 201 during the rotation. As the auger blades 204 continue to rotate, the raw materials are continuously transported to the hose 4, thereby realizing the transportation of raw materials.
[0035] In one embodiment, the sliding mechanism 5 includes a circular slider 501, which is sleeved on the outer wall of the housing 201 and slidably mounted with two guide blocks 205. Hinges 502 are symmetrically fixedly mounted at both ends of the circular slider 501.
[0036] The lifting mechanism 6 includes two first hinge rods 601 and a fixing block 604. The bottom ends of the two first hinge rods 601 are rotatably mounted on the support frame 1, and the top ends of the two first hinge rods 601 are rotatably mounted with connecting blocks 602.
[0037] The top ends of the two first hinge rods 601 are rotatably connected to the second hinge rods 603, and the two connecting blocks 602 are rotatably installed with the two second hinge rods 603 respectively. The other ends of the two second hinge rods 603 are rotatably installed on the fixed block 604. The top of the fixed block 604 is fixedly installed with two connecting rods 605, and the two connecting rods 605 are respectively hinged to the two hinge blocks 502.
[0038] The drive mechanism 7 includes a bidirectional threaded screw 701 with symmetrical and opposite threads on the bidirectional threaded screw 701. The two threads on the bidirectional threaded screw 701 are respectively threadedly installed with two connecting blocks 602. Anti-disengagement blocks 702 and handwheels 703 are respectively fixedly installed at both ends of the bidirectional threaded screw 701.
[0039] When the height of the housing 201 needs to be adjusted, the operator manually turns the handwheel 703 to rotate the double-threaded screw 701. Since the two threads on the double-threaded screw 701 are respectively threaded onto the two connecting blocks 602, as the double-threaded screw 701 rotates, the two connecting blocks 602 will move towards or away from each other along the double-threaded screw 701. The anti-detachment block 702 is to prevent the connecting block 602 from moving excessively and causing the connecting block 602 to detach from the double-threaded screw 701.
[0040] The top ends of both first hinge rods 601 are rotatably mounted on connecting block 602. Connecting block 602 is also rotatably mounted on second hinge rod 603. When connecting block 602 moves, it causes the first hinge rods 601 and second hinge rods 603 to change angles. The bottom ends of the two first hinge rods 601 are rotatably mounted on support frame 1. The two second hinge rods 603 are also rotatably mounted on fixed block 604. As connecting block 602 moves, the structure formed by the first hinge rods 601, second hinge rods 603, support frame 1, and fixed block 604 deforms, meaning the height of fixed block 604 also changes. Since fixed block 604 is hinged to hinge block 502 via connecting rod 605, circular slider 501 is sleeved on housing 201, and guide blocks 2 are symmetrically arranged with respect to the outer wall of housing 201. 05 Sliding installation: The two ends of the circular slider 501 are symmetrically fixed with hinge blocks 502. When the two second hinge rods 603 drive the hinge blocks 502 to move through the fixed block 604 and the connecting rod 605, the circular slider 501 slides along the trajectory of the guide block 205, thereby realizing the lifting and lowering of the housing 201 driven by the circular slider 501. Because the bottom of the housing 201 is rotatably mounted on the support frame 1, the screw feeding mechanism 2 will rotate around the rotating connection point on the support frame 1 during the lifting and lowering process. Since the hose 4 is connected to the housing 201, the height of the hose 4 can be flexibly adjusted. In this way, the hose 4 can be flexibly adjusted according to the height of the mixing equipment, effectively eliminating the height difference between the hose 4 and the mixing equipment, and fundamentally preventing the phenomenon of raw material spillage.
