Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cotton filling equipment, specifically a cotton filling device for a seat cushion. Background Technology
[0002] Cotton filling equipment is mainly used to fill plush toys, sofa cushions, pillows and seat cushions with cotton or other filling materials. They are usually characterized by high efficiency and precision, which can significantly improve production efficiency and the quality of filled products. In the furniture manufacturing industry, the quality of seat cushion filling materials directly affects the comfort and service life of the seat cushion.
[0003] According to the search results, Chinese patent document, publication number CN 213387795 U, discloses a cotton filling device for modular sofas, belonging to the field of mechanical technology. It solves the technical problems of existing cotton filling machines, such as the inability to replace the filling head as needed. This cotton filling device for modular sofas includes a base. Its features include a mixing box and a filling box on the base. The mixing box has a dispersing structure, a feeding box, and a feeding structure. The filling box has several filling pipes and an adjustment structure. The mixing box and the filling box are connected by a connecting pipe, on which a filling fan is mounted. The filling fan is fixed to the base. This invention has the advantage of good performance.
[0004] The above-mentioned technology also has certain shortcomings. For example, although a stirring shaft and stirring rod are installed in the mixing box, the stirring rod can only perform unidirectional stirring and dispersing in the horizontal direction. This single stirring method cannot simultaneously disperse the cotton in the vertical direction in the mixing box, resulting in the cotton fibers not being fully fluffed. In addition, cotton is prone to compaction and clumping during storage and transportation. If the clumped cotton is directly filled into the cushion, it will not only reduce the uniformity of cotton fiber distribution and fluffiness in the cushion, but also directly affect the production quality of the cushion. Therefore, we provide a cotton filling device for cushions to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cushion filling device, comprising a workbench, an installation platform fixedly connected to the top of the workbench, and a stirring tank fixedly connected inside the installation platform. A stirring mechanism is provided inside the stirring tank. A receiving groove is provided inside the workbench, with the inlet of the receiving groove facing the outlet of the stirring tank.

At the same time, the dual-output motor drives the stirring blade to rotate horizontally through the support rod. This bidirectional compound motion can perform three-dimensional dispersing treatment on cotton, ensuring that the cotton fibers are fully fluffed, laying the foundation for high-quality filling in the future.
[0015] Second, this utility model, through the clamping mechanism, activates the electric push rod through the controller, driving the clamping block two to move smoothly upward along the guide block track, forming a cooperative clamping mechanism with the fixed clamping block one, effectively preventing fiber scattering during the filling process, ensuring the cleanliness of the working environment, and realizing fully automated clamping operation.

[0022] 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.
[0023] like Figure 1-4 As shown, this utility model provides a technical solution: a cushion filling device, including a workbench 1, an installation platform 2 fixedly connected to the top of the workbench 1, and a stirring tank 3 fixedly connected inside the installation platform 2. A stirring mechanism 4 is provided inside the stirring tank 3. A receiving groove 6 is opened inside the workbench 1, and the inlet of the receiving groove 6 faces the outlet of the stirring tank 3. A connecting pipe 7 is fixedly connected inside the receiving groove 6, and a filling fan 8 is fixedly connected to one end of the connecting pipe 7. A filling pipe 9 is fixedly connected to one end of the filling fan 8, and a clamping mechanism 5 is provided on the outer wall of the filling pipe 9. An installation column 10 is inserted into the outer wall of the filling pipe 9. A placement platform 11 is slidably connected to the top of the workbench 1, and a threaded rod 12 is threadedly connected to the bottom end of the placement platform 11. A servo motor 13 is fixedly connected to one end of the threaded rod 12.
[0024] First, the controller synchronously starts the servo motor 14 and the stirring mechanism 4, causing the stirring mechanism 4 to perform a compound motion. The servo motor 14 drives the stirring mechanism 4 to rotate vertically, so that the stirring roller 15 and the stirring mechanism 4 form a vertical stirring trajectory. At the same time, the stirring mechanism 4 rotates horizontally. This bidirectional compound motion can perform three-dimensional dispersing treatment on the cotton, ensuring that the cotton fibers are fully fluffed, laying the foundation for high-quality filling later. Then, the solenoid valve is opened, and the processed cotton is guided from the stirring tank 3 to the receiving tank 6. When the controller starts the filling fan 8, the system extracts the high-quality cotton fibers from the bottom of the receiving tank 6 through the connecting pipe 7, forming a continuous and stable cotton conveying flow through the filling pipe 9. At this time, the operator needs to... The filled cushion is positioned on the movable placement platform 11, and the cushion's cotton inlet is connected to the cotton outlet of the filling tube 9. After connection, the clamping mechanism 5 is activated by the controller, driving it to move smoothly upwards. This forms a cooperative clamping mechanism with the fixed clamping mechanism 5, effectively preventing fiber scattering during the filling process. This ensures a clean working environment and achieves fully automated clamping operation. Finally, the servo motor 13 drives the threaded rod 12, causing the placement platform 11 to perform displacement movement. The placement platform 11 can automatically adjust the cushion's spatial position according to the filling progress, ensuring that the cotton is evenly distributed inside the cushion. This solves the problem of uneven filling caused by the need for manual adjustment of the cushion position, improving production efficiency and product quality.
[0025] like Figure 1-3As shown, the stirring mechanism 4 includes a stirring rod 401, a receiving block 402, a dual-output motor 403, a support rod 404, and a stirring blade 405. Both ends of the multiple receiving blocks 402 are fixedly connected to the outer wall of the stirring rod 401. The output end of the dual-output motor 403 is fixedly connected to one end of the support rod 404, and the outer wall of the support rod 404 is fixedly connected to the inside of the stirring blade 405. The bottom end of the dual-output motor 403 is fixedly connected to the inside of the receiving block 402. A servo motor 14 is fixedly connected to the top of the stirring rod 401. The end of the support rod 404 away from the receiving block 402 is slidably connected to the inner wall of the stirring tank 3. Two stirring rollers 15 are fixedly connected to the outer wall of the stirring rod 401, and the two stirring rollers 15 are distributed at equal intervals.
[0026] First, the servo motor 14 and the dual-output motor 403 are started synchronously by the controller to drive the stirring mechanism 4 to perform compound motion: the servo motor 14 drives the stirring rod 401 to rotate vertically, so that the stirring roller 15 and the stirring blade 405 form a vertical stirring trajectory. At the same time, the dual-output motor 403 drives the stirring blade 405 to rotate horizontally through the support rod 404. This bidirectional compound motion can perform three-dimensional dispersing treatment on the cotton, ensuring that the cotton fibers are fully fluffed, laying the foundation for high-quality filling in the future.
[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the clamping mechanism 5 includes a first clamping block 501, a second clamping block 502, a guide block 503, and an electric push rod 504. The output end of the electric push rod 504 is fixedly connected to the bottom end of the second clamping block 502. One side of the guide block 503 is fixedly connected to one end of the second clamping block 502. The first clamping block 501 is located above the second clamping block 502. The cotton filling tube 9 is located on the opposite side of the first clamping block 501 and the second clamping block 502. One end of the first clamping block 501 is fixedly connected to one side of the mounting column 10. One end of the guide block 503 is slidably connected to one side of the mounting column 10. The bottom end of the electric push rod 504 is fixedly connected to the top end of the worktable 1.
[0028] The controller activates the electric push rod 504, driving the clamping block 502 to move smoothly upward along the guide block 503 track, forming a cooperative clamping mechanism with the fixed clamping block 501. This effectively prevents fiber scattering during the filling process, ensuring a clean working environment and achieving fully automated clamping operation. Finally, the servo motor 13 drives the threaded rod 12 to perform displacement movement, which automatically adjusts the position of the cushion according to the filling progress, ensuring that the cotton is evenly distributed inside the cushion. This solves the problem of uneven filling caused by the need for manual adjustment of the cushion position, improving production efficiency and product quality.
[0029] Working principle: First, the controller synchronously starts servo motor 14 and dual-output motor 403, driving the stirring mechanism 4 to perform compound motion: servo motor 14 drives the stirring rod 401 to rotate vertically, so that the stirring roller 15 and stirring blade 405 form a vertical stirring trajectory. At the same time, the dual-output motor 403 drives the stirring blade 405 to rotate horizontally through the support rod 404. This bidirectional compound motion can perform three-dimensional dispersing treatment on the cotton. Then, the solenoid valve is opened, and the processed cotton is guided from the stirring tank 3 to the receiving tank 6. When the controller starts the cotton filling fan 8, the system draws the cotton from the receiving tank through the connecting pipe 7. The high-quality cotton fibers at the bottom layer form a continuous and stable cotton conveying flow through the filling tube 9. At this time, the operator needs to position the cushion to be filled on the movable placement platform 11 and connect the cushion's cotton inlet with the cotton outlet of the filling tube 9. After the connection is completed, the controller activates the electric push rod 504, which drives the clamping block 2 502 to move smoothly upward along the guide block 503 track, forming a cooperative clamping mechanism with the fixed clamping block 1 501, effectively preventing fiber scattering during the filling process. Finally, the servo motor 13 is started to drive the threaded rod 12 to perform displacement movement, and the placement platform 11 can automatically adjust the spatial position of the cushion according to the filling progress.
