Description

Technical Field

[0001] This utility model relates to the field of filling technology, and specifically to a rotary filling device. Background Technology

[0002] In industrial production, filling high-viscosity fluids has always been a highly challenging technical problem. With the continuous development of industry, the application of various high-viscosity materials, such as adhesives, sauces, and high-viscosity chemical agents, is becoming increasingly widespread, and the requirements for their filling efficiency and quality are becoming more and more stringent.

[0003] Existing high-viscosity fluid filling machines typically use gear pumps to draw raw materials from a storage tank and inject them into the container through a filling nozzle via pipes. However, due to the poor flowability of high-viscosity materials, they often accumulate in the center of the filling tank after injection, making it difficult to distribute them evenly around the perimeter. This not only leads to uneven distribution of the material within the tank but also causes it to accumulate continuously during the filling process, even overflowing the tank, thus affecting production efficiency and product quality.

[0004] Therefore, there is an urgent need for a filling equipment that can effectively solve the problem of uniformity in filling high-viscosity fluids, in order to improve production efficiency and product quality. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rotary filling device.

[0006] This application provides a technical solution that adopts the following approach:

[0007] A rotary filling device includes a rotating platform for placing filling barrels, a lifting device (1) for driving the rotating platform to rise and fall, and a conveying pipe for injecting materials into the filling barrels; one end of the conveying pipe is connected to a material storage tank, and the discharge end of the conveying pipe is set off from the rotation center of the rotating platform.

[0008] By adopting the above technical solution, when the rotary table drives the filling barrel to rotate, the high-viscosity material flows out from the filling nozzle near the inner wall of the barrel. Due to the poor flowability of the high-viscosity material, under the action of centrifugal force and rotation, the high-viscosity material can be deposited layer by layer from the edge of the barrel in a spiral trajectory, and evenly spread throughout the entire filling barrel. This effectively avoids the accumulation of high-viscosity material in the central area of ​​the filling barrel, ensures the uniformity of filling, and improves product quality.

[0009] Preferably, the lifting device includes a base, a scissor lift arm, and a lifting platform. The scissor lift arm is disposed above the base, and the lifting platform is disposed above the scissor lift arm. The scissor lift arm is provided with a hydraulic cylinder for driving the scissor lift arm to lift. The rotary table is rotatably mounted on the side of the lifting platform away from the scissor lift arm.

[0010] By adopting the above technical solution, the scissor lift arm structure possesses excellent stability and load-bearing capacity. Driven by a hydraulic cylinder, it enables the lifting platform to rise and fall smoothly. During the filling process, the height of the lifting platform can be flexibly adjusted according to changes in the liquid level within the filling container, ensuring that the filling nozzle maintains a suitable distance from the liquid surface, preventing the nozzle from being submerged by the material, and also ensuring better material distribution under centrifugal force, further improving filling quality. Moreover, this lifting structure is suitable for filling containers of different heights, enhancing the equipment's versatility.

[0011] Preferably, the lifting platform has a connecting hole on the side away from the scissor lift arm, and a first bearing seat is fixedly installed in the connecting hole. A rotating shaft is fixedly installed on the side of the rotating platform close to the lifting platform, and the end of the rotating shaft away from the rotating platform is rotatably installed in the first bearing seat. A control component for driving the rotating platform to rotate is fixedly installed on the lifting platform, and the control component is located between the lifting platform and the rotating platform.

[0012] By adopting the above technical solution, the rotating shaft on the rotary table is rotatably installed in the first bearing housing. The first bearing housing provides stable support for the rotation of the rotary table, reducing friction and shaking during rotation, and enabling the rotary table to drive the filling barrels to rotate more smoothly. The control components are installed between the lifting platform and the rotary table, with a compact structure that is easy to install and maintain. At the same time, this layout allows the control components to drive the rotary table more precisely, ensuring that the rotary table rotates at the set speed and direction, providing reliable power for uniform filling of materials.

[0013] Preferably, the scissor lift includes two inner booms and an outer boom, which are arranged crosswise. The middle parts of the outer booms and inner booms are connected by a scissor shaft. The tops of the two outer booms are hinged to the side of the lifting platform away from the rotary table, and the bottoms of the two outer booms are slidably connected to the base. The tops of the two inner booms are slidably connected to the side of the lifting platform away from the rotary table, and the bottoms of the two inner booms are hinged to the base.

[0014] By adopting the above technical solution, the interlocking inner and outer booms, connected by the scissor lift shaft, form a stable scissor lift structure. The top of the outer boom is hinged to the lifting platform, and the bottom is slidably connected to the base. The bottom of the inner boom is hinged to the base, and the top is slidably connected to the lifting platform. This connection method ensures that the scissor lift arm maintains good stability and synchronization during lifting. Under the action of the hydraulic cylinder, the inner and outer booms can move in tandem, achieving smooth rising and falling of the lifting platform and providing stable lifting support for the turntable and filling barrels. Even when the equipment operates for extended periods or carries heavy filling barrels, this structure ensures that the lifting platform will not tilt or jam, guaranteeing the reliability of the equipment operation.

[0015] Preferably, the control component includes a worm gear, a worm, and a drive motor. The lifting platform is provided with a mounting block and a second bearing seat, which are arranged parallel to the mounting block. The drive motor is mounted on the mounting block with its output end facing the second bearing seat. One end of the worm is rotatably mounted in the second bearing seat, and the end of the worm away from the second bearing seat is fixedly connected to the output end of the drive motor. The worm gear is fixedly mounted on a rotating shaft, and the worm meshes with the worm.

[0016] By adopting the above technical solution, the worm gear drive features a large transmission ratio and good self-locking performance. After the drive motor starts, it drives the worm to rotate, which in turn drives the worm wheel meshing with it to rotate. The worm wheel is fixedly mounted on the rotating shaft, thereby causing the rotary table on the rotating shaft to rotate. The large transmission ratio allows the drive motor to output at a relatively low speed, achieving a relatively low and stable speed of the rotary table. This facilitates precise control of the rotary table's rotation speed, meeting the speed requirements for filling different materials. Simultaneously, the self-locking performance ensures that the rotary table will not rotate arbitrarily due to external forces after the drive motor stops working, ensuring the stability and safety of the filling process.

[0017] Preferably, a lower cross brace is provided between the two outer booms, and an upper cross brace is provided between the two inner booms, with the lower cross brace and the upper cross brace being horizontally arranged respectively.

[0018] By adopting the above technical solution, the lower and upper cross braces enhance the overall structural strength and stability of the scissor lift boom. The lower cross brace connects the two outer booms, and the upper cross brace connects the two inner booms. These effectively prevent twisting and deformation of the inner and outer booms during lifting, ensuring the scissor lift boom can still operate normally under load. This structural design makes the stress on various parts of the scissor lift boom more even during lifting, further improving the reliability and service life of the equipment. Even with frequent lifting and lowering during long-term, high-intensity production operations, the scissor lift boom maintains good structural performance, reducing the frequency of equipment maintenance and parts replacement, and lowering production costs.

[0019] Preferably, there are two hydraulic cylinders, and the two ends of the two hydraulic cylinders are respectively hinged to the lower cross brace and the upper cross brace.

[0020] By adopting the above technical solution, the two hydraulic cylinders work simultaneously, providing greater driving force and ensuring the smooth lifting and lowering of the scissor lift arm. Furthermore, by hinged at both ends of the hydraulic cylinders to the lower and upper cross braces respectively, the force of the hydraulic cylinders can be evenly transmitted to the entire scissor lift arm structure, avoiding excessive localized stress.

[0021] Preferably, the bottom of the two outer booms is provided with a first pulley, and the base is provided with a first slide rail that cooperates with the first pulley.

[0022] By adopting the above technical solution, the cooperation between the first pulley and the first slide rail reduces the friction between the bottom of the boom and the base, making the sliding of the boom smoother during lifting. This structure reduces energy consumption during equipment operation, reduces wear between components, and extends the service life of the equipment. Simultaneously, the cooperation between the first pulley and the first slide rail also acts as a guide, ensuring that the boom moves along a predetermined trajectory during lifting, further improving the stability and accuracy of the scissor lift. During long-term operation, this design effectively reduces lifting errors caused by friction and component wear, ensuring the equipment always maintains good working condition.

[0023] Preferably, the top of the two inner booms is provided with a second pulley, and the side of the lifting platform away from the rotary table is provided with a second slide rail that cooperates with the second pulley.

[0024] By adopting the above technical solution, the cooperation between the second pulley and the second slide rail functions similarly to that between the first pulley and the first slide rail. It reduces the friction between the top of the inner boom and the lifting platform, making the movement of the inner boom smoother during lifting. Simultaneously, the second pulley and the second slide rail also serve a guiding function, ensuring that the inner and outer booms move in tandem during lifting, guaranteeing the levelness and stability of the lifting platform, and providing a guarantee for the stable operation of the rotary table and filling barrels.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When the rotary table drives the filling barrel to rotate, the high-viscosity material flows out from the filling nozzle near the inner wall of the barrel. Due to the poor flowability of the high-viscosity material, under the action of centrifugal force and rotation, the high-viscosity material can be deposited layer by layer from the edge of the barrel in a spiral trajectory, and evenly spread throughout the entire filling barrel. This effectively avoids the accumulation of high-viscosity material in the central area of ​​the filling barrel, ensures the uniformity of filling, and improves product quality.

[0027] 2. The scissor lift arm structure boasts excellent stability and load-bearing capacity. Driven by a hydraulic cylinder, it enables the lifting platform to rise and fall smoothly. During the filling process, the height of the lifting platform can be flexibly adjusted according to changes in the liquid level within the filling container, ensuring that the filling nozzle maintains a suitable distance from the liquid surface, preventing the nozzle from being submerged in material. This also ensures better material distribution under centrifugal force, further improving filling quality. Moreover, this lifting structure is suitable for filling containers of varying heights, enhancing the equipment's versatility.

[0028] 3. The interlocking inner and outer booms, connected by the scissor lift shaft, form a stable scissor lift structure. The top of the outer boom is hinged to the lifting platform, and the bottom is slidably connected to the base. The bottom of the inner boom is hinged to the base, and the top is slidably connected to the lifting platform. This connection method ensures good stability and synchronization of the scissor lift during lifting. Under the action of the hydraulic cylinder, the inner and outer booms can move in tandem, achieving smooth rising and falling of the lifting platform and providing stable lifting support for the turntable and filling barrels. Even when the equipment operates for extended periods or carries heavy filling barrels, this structure ensures that the lifting platform will not tilt or jam, guaranteeing the reliability of the equipment operation.

[0035] This application discloses a rotary filling device.

[0036] A rotary filling device, as described in the reference Figure 1 and Figure 2 The system includes a lifting device 1, a rotating platform 2, and a conveying pipe 3. The rotating platform 2 is rotatably mounted on the lifting device 1, and the side of the rotating platform 2 facing away from the lifting device 1 is used to place the filling barrel. The conveying pipe 3 is located above the filling barrel, and one end of the conveying pipe 3 is fixedly installed on and connected to a material storage tank. A filling nozzle 4 is fixedly installed at the end of the conveying pipe 3 away from the material storage tank, and the end of the conveying pipe 3 near the filling nozzle 4 faces the filling barrel and is offset from the rotation axis of the filling barrel. By offsetting the end of the conveying pipe 3 near the filling nozzle 4 from the rotation axis of the filling barrel, when the rotating platform 2 drives the filling barrel to rotate, the high-viscosity material enters the barrel from the edge, and can be filled more evenly throughout the filling barrel under the action of rotation.

[0037] Specifically, the lifting device 1 includes a base 11, a scissor lift arm 12, and a lifting platform 13. One end of the scissor lift arm 12 is mounted on the base 11, and the lifting platform 13 is mounted on the end of the scissor lift arm 12 away from the base 11. A hydraulic cylinder 5 for driving the scissor lift arm 12 to lift is mounted on the scissor lift arm 12. A rotary table 2 is located on the side of the lifting platform 13 opposite to the scissor lift arm 12.

[0038] Furthermore, the scissor lift boom 12 includes two outer boom frames 121 and an inner boom frame 122, which are arranged crosswise and connected at their midpoints by a scissor shaft 6. One end of each of the two outer boom frames 121 is hinged to the side of the lifting platform 13 away from the rotary table 2, and a first pulley 7 is provided at the end of each of the two outer boom frames 121 away from the lifting platform 13. A first slide rail 8 that slides and engages with the first pulley 7 is provided on the base 11. One end of each of the two inner boom frames 122 is hinged to the base 11, and a second pulley 9 is provided at the end of each of the two inner boom frames 122 away from the base 11. A second slide rail 14 that slides and engages with the second pulley 9 is provided on the side of the lifting platform 13 away from the rotary table 2.

[0039] A lower cross brace 15 is provided between the two outer booms 121, and the two outer booms 121 are connected by the lower cross brace 15; an upper cross brace 16 is provided between the two inner booms 122, and the two inner booms 122 are connected by the upper cross brace 16. There are two hydraulic cylinders 5, and the two ends of the two hydraulic cylinders 5 are respectively hinged to the lower cross brace 15 and the upper cross brace 16.

[0040] Specifically, the lifting platform 13 has a connecting hole 17 on the side near the rotating platform 2, and a first bearing seat 18 is fixedly installed in the connecting hole 17. The rotating platform 2 has a rotating shaft 19 on the side near the lifting platform 13. The rotating platform 2 passes through the rotating shaft 19 and is rotatably mounted on the lifting platform 13. The lifting platform 13 is also provided with a control component 20 for driving the rotating platform 2 to rotate. The control component 20 is fixedly installed between the lifting platform 13 and the rotating platform 2.

[0041] During material filling, the lifting platform 13 is first raised to its highest position via the scissor lift arm 12 and hydraulic cylinder 5. At this point, the end of the conveying pipe 3 near the filling nozzle 4 extends into the filling barrel, and the filling nozzle 4 is offset from the rotation center of the filling barrel and close to the inner wall of the filling barrel. Subsequently, the control component 20 drives the rotary table 2 to rotate the filling barrel, and at the same time, the material conveying is activated, allowing the high-viscosity material to continuously flow out from the filling nozzle 4. Due to the rotation of the filling barrel, the material is deposited layer by layer from the edge of the barrel in a spiral trajectory, and under the action of centrifugal force, it is evenly spread throughout the entire barrel, avoiding accumulation in the center. During the filling process, the lifting platform 13 is gradually lowered via the scissor lift arm 12 and hydraulic cylinder 5 to ensure that the filling nozzle 4 and the high-viscosity material in the filling barrel maintain a certain distance, preventing the filling nozzle 4 from being submerged due to the rise of the filling liquid level.

[0042] Furthermore, the control component 20 includes a worm gear 201, a worm 202, and a drive motor 203. A mounting block 21 and a second bearing seat 22 are fixedly installed between the lifting platform 13 and the rotary table 2, with the mounting block 21 and the second bearing seat 22 arranged parallel to each other. The drive motor 203 is fixedly mounted on the mounting block 21, with its output end facing the second bearing seat 22. One end of the worm 202 is rotatably mounted on the second bearing seat 22, and the end of the worm 202 away from the second bearing seat 22 is fixedly connected to the output end of the drive motor 203. The worm gear 201 is fixedly fitted onto the rotating shaft 19 on one side of the rotary table 2 and meshes with the worm 202. The drive motor 203 controls the rotation of the worm 202, and the worm gear 201 meshing with the worm 202 then drives the rotary table 2 on the rotating shaft 19 to perform circular motion.

[0043] The implementation principle of the application embodiment is as follows: Before the filling operation, the high-viscosity material is placed in the material storage tank, and the filling barrel is placed on the rotary table 2. After the equipment is started, the hydraulic cylinder 5 of the lifting device 1 drives the scissor lift arm 12. Utilizing the sliding cooperation between the first pulley 7 at the bottom of the outer boom 121 and the first slide rail 8 of the base 11, the second pulley 9 at the top of the inner boom 122 and the second slide rail 14 of the lifting platform 13, and the enhanced structural strength of the lower cross brace 15 and the upper cross brace 16, the lifting platform 13 is raised, allowing the filling nozzle 4 on the conveying pipe 3 to reach a position offset from the rotation axis of the filling barrel. Then, the drive motor 203 of the control component 20 drives the worm gear 202 to rotate, which, through meshing with the worm wheel 201, causes the rotary table 2 to rotate, and the filling barrel rotates accordingly. At this time, the material conveying is activated, and the high-viscosity material flows out from the filling nozzle 4, and is evenly distributed inside the barrel under the action of centrifugal force and rotation. During the filling process, to prevent the filling nozzle 4 from being submerged, the hydraulic cylinder 5 controls the scissor lift arm 12 to descend, driving related components to descend synchronously, ultimately achieving efficient and uniform filling of high-viscosity materials, improving production efficiency and product quality.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
