Description

Technical Field

[0001] This invention relates to the field of mixer technology, and in particular to a mixing machine with a transfer function that prevents pinching of pellets and has a lifting hopper. Background Technology

[0002] A mixer is a mechanical device that uses mechanical force and gravity to uniformly mix two or more materials. During the mixing process, it can increase the contact surface area of ​​the materials to promote chemical reactions and accelerate physical changes. Commonly used mixers are divided into four main categories: gas and low-viscosity liquid mixers, medium- and high-viscosity liquid and paste mixers, and powder and granular solid material mixers. The moving parts of the mechanical agitator exert a shearing effect on the liquid or powder when rotating. When the liquid flows through the container wall and various fixed components installed inside the container, it is also subjected to shearing action. These shearing actions induce many local eddy currents, thereby mixing the materials.

[0003] In existing technologies, when using a hopper to transfer mixed materials, it is often necessary to manually transport the hopper to the mixer. Furthermore, after the hopper is filled with material, it is also necessary to manually move the hopper, making the operation quite cumbersome. Therefore, we propose an anti-clamping hopper lifting mixer with a transfer function to solve the above-mentioned problems. Summary of the Invention

[0004] This invention provides an anti-clamping pellet distribution hopper lifting and mixing machine with a transfer function, which solves the problem of the cumbersome operation caused by the manual transfer of the distribution hopper in the prior art.

[0005] This invention provides the following technical solution:

[0006] A lifting and mixing machine with anti-pinch shot distribution hopper and transfer function includes a lifting mixer. A base plate is fixedly installed at the bottom of the lifting mixer, and a support frame is fixedly installed at the top of the base plate. A tray is slidably connected to the support frame, and a distribution hopper is placed through the tray. A cover plate is fitted to the opening of the distribution hopper. The mixer also includes:

[0007] The measuring mechanism is installed on the pallet and is used to weigh the material in the dispensing hopper.

[0008] The moving mechanism is installed on top of the support frame and is connected to the top of the tray;

[0009] The transfer mechanism is installed on the top of the base plate and is used to clamp and transport the material hopper.

[0010] The suction mechanism is installed on the transfer mechanism and is used to suction the cover plate to remove or clamp it from the hopper.

[0011] In one possible design, the metering mechanism includes multiple gravity sensors fixedly installed at equal intervals on the top of the pallet, with the same force ring fixedly installed on the top of the multiple gravity sensors, and a distribution hopper passing through the force ring and resting on the force ring.

[0012] In one possible design, the moving mechanism includes a first mounting plate and a second mounting plate fixedly mounted on the top of the support frame. A first screw and a second screw are rotatably connected to one side of the first mounting plate. Two threaded plates are symmetrically fixedly mounted on the top of the support plate. The first screw and the second screw pass through the corresponding threaded plates and are threadedly connected to the threaded plates. One end of the first screw and one end of the second screw are rotatably connected to one side of the second mounting plate. A drive motor is fixedly mounted on the other side of the first mounting plate. The output shaft of the drive motor passes through the first mounting plate and is fixedly connected to the other end of the first screw. The same belt assembly is connected to the first screw and the second screw.

[0013] In one possible design, the belt assembly includes two synchronous pulleys, which are respectively fixedly sleeved on the first screw and the second screw, and the same synchronous belt is driven on the two synchronous pulleys.

[0014] In one possible design, the transfer mechanism includes a support box fixedly installed on one side of the top of the base plate. A rotating cover is rotatably connected to the support box. A limiting conical tube is fixedly installed inside the rotating cover. A stepper motor is fixedly installed inside the support box. The output shaft of the stepper motor is fixedly connected to the bottom of the rotating cover. An electric push rod is fixedly installed on the bottom inner wall of the rotating cover. A push rod is fixedly installed on the output shaft of the electric push rod. The top end of the push rod passes through the limiting conical tube and extends above the limiting conical tube. The push rod is slidably connected to the inner wall of the limiting conical tube. A support plate is fixedly installed on the top end of the push rod. A clamping assembly is installed at the bottom of the support plate. The clamping assembly is used to clamp the dispensing hopper. A suction mechanism is installed at the bottom of the support plate.

[0015] In one possible design, the clamping assembly includes a mounting frame fixedly installed at the bottom of a support plate. Two movable plates are symmetrically arranged inside the mounting frame. Two sliding holes are symmetrically opened on the support plate. The top of the movable plate passes through the corresponding sliding hole and extends to the top of the support plate. The movable plate is slidably connected to the inner wall of the sliding hole. The bottom of the movable plate extends to the bottom of the mounting frame and is fixedly installed with a clamping plate. The two clamping plates cooperate to clamp and position the distributing hopper. Push rod motors are fixedly installed on both sides of the mounting frame. The output shaft of the push rod motor is fixedly connected to one side of the corresponding movable plate.

[0016] In one possible design, limiting plates are fixedly installed on both sides of the movable plate, and two limiting holes are symmetrically opened on the inner walls of both sides of the mounting frame. The limiting plates pass through the corresponding limiting holes and are slidably connected to the inner walls of the limiting holes.

[0017] In one possible design, the suction mechanism includes a support cover fixedly installed at the bottom of a support plate, the support cover being located inside a mounting frame, the bottom of the support cover extending below the mounting frame, a cylinder fixedly installed inside the support cover, a piston plate fixedly installed on the piston rod of the cylinder, the piston plate being tightly slidably connected to the inner wall of the support cover, a plurality of air holes equally spaced on the inner wall of the support cover, all located between the cylinder and the piston plate, a suction tube fixedly installed inside the support cover, the bottom end of the suction tube extending below the support cover and fixedly installed with a suction cup, the suction tube being connected to the suction cup.

[0018] In this invention, after the mixed material needs to be loaded into the dispensing hopper, the dispensing hopper can be placed between two clamping plates. Simultaneously, two push rod motors are activated to move the corresponding moving plates, allowing the two clamping plates to come together and stably clamp the dispensing hopper. Then, a stepper motor is activated to rotate the rotating cover, causing the dispensing hopper to move in an arc shape and move it above the support plate. Next, an electric push rod is activated to move the top rod downwards, moving the dispensing hopper onto the support plate, where a force ring supports it. Then, two push rod motors are activated to move the two clamping plates away from each other, while a cylinder is activated to move the piston plate upwards. This draws gas from the suction cup into the support cover, creating a negative pressure state within the suction cup, allowing for a tight seal of the cover plate. Then, when the electric push rod is activated to move the support plate upwards, it moves the suction cup upwards, removing the cover plate from the dispensing hopper. Finally, a drive motor is activated to drive the first screw... When the first screw rotates, it drives the second screw to rotate synchronously through the transmission cooperation of two synchronous pulleys and a synchronous belt. When the first and second screws rotate, they drive the pallet to move laterally along the support frame through the threaded transmission with the corresponding threaded plates. This moves the hopper to below the lifting mixer, making it easier to feed materials into the hopper. When feeding materials into the hopper, multiple gravity sensors weigh the materials loaded into the hopper, thus accurately controlling the loading amount. After the materials are loaded, the drive motor can be started to drive the first screw to rotate in the opposite direction. Through the reverse transmission of the structure, the hopper can be moved to below the cover plate. Then, the electric push rod is started to move the cover plate downward, so that the cover plate locks the hopper. Next, the two push rod motors are started again to rotate the hopper using two clamping plates. Then, the electric push rods and stepper motors are started respectively to move the hopper out of the pallet and transfer the hopper.

[0019] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0020] Beneficial effects: In this invention, through the metering mechanism, after the distribution hopper is moved to the bottom of the lifting mixer, multiple gravity sensors can weigh the material loaded into the distribution hopper when the material is fed into the distribution hopper, thereby accurately controlling the loading amount of the material in the distribution hopper.

[0021] In this invention, the moving mechanism can drive the first screw to rotate by starting the drive motor. At this time, under the transmission action of the belt assembly, the second screw can be driven to rotate synchronously. When the first and second screws rotate, under the thread transmission action with the corresponding threaded plate, the pallet can be driven to move laterally along the support frame, thereby moving the distributing hopper to the bottom of the lifting mixer, so as to facilitate the feeding of materials into the distributing hopper. After the materials are fed into the distributing hopper, the drive motor can be started to drive the first screw to rotate in the opposite direction. Through the reverse transmission of the structure, the distributing hopper can be moved to the initial position.

[0022] In this invention, the transfer mechanism allows the material hopper to be clamped by the clamping assembly. Then, an electric push rod can be activated to move the top rod longitudinally, which in turn moves the support plate longitudinally. This allows the material hopper to move synchronously via the clamping assembly, moving it from the pallet into or out of the tray. Finally, a stepper motor is activated to rotate the rotating cover, causing the material hopper to move in an arc shape, facilitating automatic transfer of the material hopper.

[0023] In this invention, the suction mechanism allows the suction cup and cover plate to be tightly bonded. Then, a cylinder can be activated to move the piston plate upwards, drawing gas from the suction cup into the support cover and creating a negative pressure within the suction cup. This ensures a tight seal with the cover plate. Subsequently, when the electric push rod is activated to move the support plate upwards, the suction cup moves upwards, removing the cover plate from the hopper. After the hopper is filled with material and moved below the cover plate, the electric push rod can be activated to move the top rod downwards, simultaneously moving the cover plate downwards and engaging it with the hopper.

[0024] This invention enables the automatic movement and filling of material distribution hoppers, and after the hoppers are filled with materials, the invention enables the automatic transfer of the hoppers, thereby improving the level of automation, reducing the labor intensity of workers, and providing excellent ease of use.

[0035] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the devices are connected to each other and their relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of the present invention, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, and are not intended to indicate or imply that the device or element 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 embodiments of the present invention.

[0036] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0037] In this embodiment of the invention, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0038] References to "one embodiment" or "some embodiments" as used in this specification mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the invention. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless otherwise specifically emphasized.

[0039] Example 1: Refer to Figures 1-7 This embodiment of a mixer includes a lifting mixer 1. A base plate 2 is fixedly installed at the bottom of the lifting mixer 1, and a support frame 3 is fixedly installed at the top of the base plate 2. A tray 4 is slidably connected to the support frame 3, and a distributing hopper 7 is placed through the tray 4. A cover plate 8 is fitted into the opening of the distributing hopper 7. Furthermore, the mixer also includes the following mechanisms:

[0040] The metering mechanism consists of multiple gravity sensors 5 fixedly installed at equal intervals on the top of the pallet 4. A force-bearing ring 6 is fixedly installed on the top of the multiple gravity sensors 5. The distribution hopper 7 passes through the force-bearing ring 6 and is mounted on the force-bearing ring 6. When the distribution hopper 7 moves to the bottom of the lifting mixer 1 to feed materials, the multiple gravity sensors 5 can jointly weigh the material loaded into the distribution hopper 7, ensuring the accuracy of the loading amount of material in the distribution hopper 7.

[0041] The moving mechanism is as follows: A first mounting plate 9 and a second mounting plate 10 are fixedly installed on the top of the support frame 3. A first screw 12 and a second screw 13 are rotatably connected to one side of the first mounting plate 9. Two threaded plates 16 are symmetrically fixedly installed on the top of the support plate 4. The first screw 12 and the second screw 13 pass through the corresponding threaded plates 16 and are threadedly connected to them. One end of the first screw 12 and one end of the second screw 13 are rotatably connected to one side of the second mounting plate 10. A drive motor 11 is fixedly installed on the other side of the first mounting plate 9. The output shaft of the drive motor 11 passes through the first mounting plate 9 and is fixedly connected to the other end of the first screw 12. At the same time, a belt assembly is connected to both the first screw 12 and the second screw 13. The belt assembly includes two synchronous pulleys 14 and a synchronous belt 15. The two synchronous pulleys 14 are fixedly sleeved on the first screw 12 and the second screw 13, respectively, and the synchronous belt 15 is driven and sleeved on the two synchronous pulleys 14. When the drive motor 11 is started, its output shaft drives the first screw 12 to rotate. Simultaneously, through the transmission of the two synchronous pulleys 14 and the synchronous belt 15, the second screw 13 rotates synchronously. As the first screw 12 and the second screw 13 rotate, the threaded transmission with the corresponding threaded plate 16 drives the pallet 4 to move laterally along the support frame 3, thereby moving the distribution hopper 7 below the lifting mixer 1 for easy material feeding. After feeding, starting the drive motor 11 again drives the first screw 12 to rotate in the opposite direction, thus moving the distribution hopper 7 back to its initial position through the reverse transmission of the structure.

[0042] The transfer mechanism is as follows: A support box 17 is fixedly installed on one side of the top of the base plate 2. A rotating cover 18 is rotatably connected to the support box 17, and a limiting conical tube 19 is fixedly installed inside the rotating cover 18. A stepper motor 20 is fixedly installed inside the support box 17, and the output shaft of the stepper motor 20 is fixedly connected to the bottom of the rotating cover 18. An electric push rod 21 is fixedly installed on the bottom inner wall of the rotating cover 18. A push rod 22 is fixedly installed on the output shaft of the electric push rod 21. The top end of the push rod 22 passes through the limiting conical tube 19 and extends above the limiting conical tube 19, and is slidably connected to the inner wall of the limiting conical tube 19. A support plate 23 is fixedly installed on the top end of the push rod 22, and a clamping assembly and a suction mechanism are installed on the bottom of the support plate 23. The clamping assembly includes a mounting frame 24 fixedly installed at the bottom of the support plate 23. Two movable plates 25 are symmetrically arranged within the mounting frame 24. Two sliding holes are symmetrically formed on the support plate 23. The top of each movable plate 25 passes through the corresponding sliding hole and extends above the support plate 23, slidingly connecting with the inner wall of the sliding hole. The bottom of each movable plate 25 extends below the mounting frame 24 and is fixedly fitted with a clamping plate 26. The two clamping plates 26 cooperate to clamp and position the distributing hopper 7. Push rod motors 28 are fixedly installed on both sides of the mounting frame 24, and the output shafts of the push rod motors 28 are fixedly connected to one side of the corresponding movable plate 25. Limiting plates 27 are fixedly installed on both sides of each movable plate 25. Two limiting holes are symmetrically formed on the inner walls of both sides of the mounting frame 24, and the limiting plates 27 pass through the corresponding limiting holes and slidely connect with the inner walls of the limiting holes. After placing the dispensing hopper 7 between the two clamping plates 26, the two push rod motors 28 can be started simultaneously to move the corresponding moving plates 25. At this time, the two clamping plates 26 will move closer together and stably clamp the dispensing hopper 7. After clamping, the electric push rod 21 can be started to drive the top rod 22 to move longitudinally, thereby driving the support plate 23 to move longitudinally, and driving the dispensing hopper 7 to move synchronously through the clamping assembly, moving the dispensing hopper 7 into or out of the support plate 4. Then, the stepper motor 20 is started to drive the rotating cover 18 to rotate, thereby driving the dispensing hopper 7 to perform an arc-shaped movement, realizing the movement and automatic transfer of the dispensing hopper 7.

[0043] This application can be used in the field of mixer technology, or in other fields applicable to this application.

[0044] Example 2: Refer to Figure 7A mixing and lifting hopper with anti-pinch shot distribution function is disclosed, belonging to the field of mixing technology. The suction mechanism specifically comprises: a support cover 29 fixedly installed at the bottom of a support plate 23, the support cover 29 being located within a mounting frame 24, and the bottom of the support cover 29 extending below the mounting frame 24. A cylinder 30 is fixedly installed inside the support cover 29, and a piston plate 31 is fixedly installed on the piston rod of the cylinder 30, the piston plate 31 being tightly slidably connected to the inner wall of the support cover 29. Multiple air holes, all located between the cylinder 30 and the piston plate 31, are evenly spaced on the inner wall of the support cover 29. A suction pipe 32 is sealed and fixedly installed inside the support cover 29, the bottom end of the suction pipe 32 extending below the support cover 29 and fixedly installed with a suction cup 33, the suction pipe 32 being connected to the suction cup 33. After the suction cup 33 is tightly attached to the cover plate 8, the cylinder 30 is activated to move the piston plate 31 upward. At this time, the gas inside the suction cup 33 is drawn into the support cover 29, creating a negative pressure state inside the suction cup 33, thereby tightly adhering to the cover plate 8. Then, the electric push rod 21 is activated to move the support plate 23 upward, which in turn moves the suction cup 33 upward, thus removing the cover plate 8 from the distribution hopper 7. After the distribution hopper 7 is filled with material and moves to below the cover plate 8, the electric push rod 21 is activated to move the top rod 22 downward, which simultaneously moves the cover plate 8 downward, causing the cover plate 8 to engage with the distribution hopper 7.

[0045] In operation, the distributing hopper 7 is first moved below the lifting mixer 1, and then material is fed into it and weighed by the metering mechanism. After feeding, the distributing hopper 7 is moved back to its initial position and clamped by the clamping assembly of the transfer mechanism. Then, the cover plate 8 is removed from the distributing hopper 7 by the suction mechanism. Next, the distributing hopper 7 is moved above the lifting mixer 1 by the transfer mechanism for unloading. After unloading, the empty distributing hopper 7 is moved back to its initial position by the transfer mechanism, and the cover plate 8 is secured back onto the distributing hopper 7 by the suction mechanism, ready for the next use. Throughout this process, the distributing hopper 7 is automatically transferred and protected against pellet clamping, improving work efficiency and safety.

[0046] However, as is well known to those skilled in the art, the working principles and wiring methods of the lifting mixer 1, gravity sensor 5, drive motor 11, stepper motor 20, electric push rod 21, push rod motor 28 and cylinder 30 are commonplace and belong to conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0047] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
