Description

Technical Field

[0001] This invention relates to the field of down feeding devices, and more particularly to a down feeding device for down filling. Background Technology

[0002] Currently, in the production and processing of down products, the feeding device used to fill down into the cut pieces or product layers usually adopts a down filling tube (or down flushing tube) structure. This type of device generally includes a down storage hopper, a conveying pipeline, and a power mechanism connected to a high-pressure blower. Its working principle is to use the negative pressure generated by the high-speed airflow to draw the fluffy down from the storage container and transport it to the cut pieces of the product to be filled through the conveying pipeline. This pneumatic conveying method is widely used in the production lines of down jackets, down comforters and other thermal insulation products because of its relatively simple structure and high conveying efficiency. It is the basic equipment for realizing down filling operations.

[0003] However, most existing down filling tubes generally lack a pre-treatment structure for effectively beating or dispersing the down. Due to the lightweight, fluffy nature of down fibers and their tendency to generate static electricity due to friction, down raw materials easily form clumps of varying sizes or become entangled in the pipes due to electrostatic adsorption during long-term storage, stacking, and pneumatic conveying. These undispersed down clumps, when directly filled into the cut pieces of the product, result in extremely uneven down distribution, with some areas being too thick and others too thin. This severely affects the warmth and smoothness of the product and can even cause blockage of the filling port, interrupting the production process.

[0004] Therefore, how to provide a down feeding device for down filling is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] One object of the present invention is to provide a down feeding device for down filling, which solves the problems mentioned in the background art.

[0006] According to an embodiment of the present invention, a down feeding device for down filling includes a down filling tank and a down filling tube. The down filling tube is fixedly installed on the surface of the down filling tank, and a placement plate is fixedly installed on the surface of the down filling tank below the down filling tube. A driving assembly is fixedly installed on the side of the down filling tube, a driven shaft is fixedly installed on the surface of the driving assembly, and a striking assembly is fixedly sleeved on the surface of the driven shaft. The striking assembly includes a hammering head, which rotates with the driven shaft and strikes the surface of the down filling tube.

[0007] The drive assembly includes a drive motor, a drive gear, and a driven gear. The drive motor is fixedly mounted on the surface of the filling tube and fixedly connected. The drive gear is fixedly mounted on the end face of the output shaft of the drive motor. The driven gear is rotatably mounted on the surface of the filling tube. The drive gear and the driven gear mesh with each other. The driven shaft is fixedly mounted on the side of the driven gear.

[0008] The striking assembly also includes a retaining ring and a connecting rope. The retaining ring is fixedly sleeved on the surface of the driven shaft, the connecting rope is fixedly installed on the surface of the retaining ring, and the striking head is fixedly installed on the other end of the connecting rope.

[0009] The driven shaft has two sets of corresponding striking components, which are evenly distributed on the surface of the driven shaft. There are three sets of connecting ropes, which are arranged in a ring array with the center of the fixed ring as the array center. The number and position of the striking heads match the number and position of the connecting ropes.

[0010] The inside of the filling tube is provided with an annular groove, and a rotating ring is rotatably installed inside the annular groove. Two sets of disturbance blades are distributed in an annular array on the inner wall of the rotating ring. A rotating gear is fixedly sleeved on the side of the rotating ring, and the rotating gear meshes with the driven gear.

[0011] Protective covers are fixedly installed on the surface of the filling tube at the locations corresponding to the drive gear, transmission gear, and driven gear.

[0012] A support base is fixedly installed on the top of the placement plate at the port of the down filling tube. A slapping plate is rotatably installed on the support base. A through groove is opened on the side of the slapping plate. A support frame is fixedly installed on the top of the placement plate near the support base. A geared motor is fixedly installed on the inner side of the support frame. A rotating disk is fixedly installed on the output shaft of the geared motor. A driving rod is fixedly installed on the surface of the rotating disk near the outermost part. The driving rod is movably inserted into the inside of the through groove.

[0013] The number of the support base, the striking plate, the rotating disk and the driving rod are two sets, and the two sets of support bases and striking plates are arranged symmetrically about the reduction motor as the axis of symmetry.

[0014] The two sets of drive rods and rotating disks are arranged in a ring array with the geared motor as the array center. The geared motor is a dual-spindle motor, and the two sets of rotating disks are symmetrically fixed at both ends of the output shaft of the geared motor.

[0015] The beneficial effects of this invention are: This invention incorporates a striking component that uses a drive motor to rotate a driven shaft. This causes a striking head, fixed to the end of a connecting rope, to continuously strike the outer wall of the filling tube. This intermittent physical vibration effectively breaks down feathers that are electrostatically adsorbed onto the inner wall of the tube, allowing them to be re-integrated into the airflow and discharged. This not only prevents long-term accumulation of down on the tube wall but also effectively prevents tube blockage caused by electrostatic adsorption, ensuring the continuity and stability of the filling process. Furthermore, the combination of nylon rope and rubber or hard plastic balls significantly reduces operating noise while achieving the striking effect.

[0016] This invention creates a rotating airflow disturbance structure on the inner wall of the down filling tube by setting a rotating ring and disturbance blades driven by a driven gear. When down passes through the down filling tube, the rotating disturbance blades can actively agitate and disperse the down in the tube, effectively breaking up down clumps and tangles formed by long-term stacking or compression. This significantly improves the dispersion and flow uniformity of the down, fundamentally solving the problem of excessive local thickness caused by down clump filling, and greatly improving the warmth retention and flatness of down-filled products.

[0017] This invention employs a beating mechanism driven by a geared motor to synchronously beat the filled down products during the filling process. As the filling tube fills the product with down, the geared motor drives a rotating disk, which, through the interaction of a drive rod and a through-slot, drives the beating plate to oscillate back and forth, effectively beating and dispersing the newly filled down in real time. This design ensures that the down is immediately and evenly distributed upon entering the product, avoiding uneven distribution caused by down accumulation in localized areas. It also eliminates the need for subsequent manual beating and dispersing, significantly improving production efficiency and product quality.

[0018] This invention achieves alternating beating actions by symmetrically arranging two sets of beating plates and driving them with dual spindle motors. When one beating plate falls to beat the down product, the other beating plate rises simultaneously, creating a staggered and continuous beating effect. This alternating beating method ensures that the down is subjected to a continuous and balanced dispersing force inside the product, further improving the uniformity of down distribution, effectively preventing down from knotting after filling, and improving the operational stability and working efficiency of the beating mechanism.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0029] Example 1 refer to Figures 1-8In this embodiment, a down filling tank 1 and a down filling tube 2 are included. The down filling tube 2 is fixedly installed on the surface of the down filling tank 1. A placement plate 3 is fixedly installed on the surface of the down filling tank 1 below the down filling tube 2. A drive assembly 4 is fixedly installed on the side of the down filling tube 2. The drive assembly 4 includes a drive motor 8, a drive gear 9, and a driven gear 10. The drive motor 8 is fixedly installed on the surface of the down filling tube 2 and fixedly connected. The drive gear 9 is fixedly installed on the end face of the output shaft of the drive motor 8. The driven gear 10 is rotatably installed on the surface of the down filling tube 2. The drive gear 9 and the driven gear 10 mesh with each other. The driven shaft 5 is fixedly installed on the side of the driven gear 10.

[0030] In specific implementation, the drive motor 8 is matched with the switch. The drive motor 8 is powered by the municipal power supply system. The drive motor 8 is a small geared motor 20. The drive motor 8 is adjusted and matched using existing technology. After matching, the drive motor 8 is started by the switch during the filling process. The drive motor 8 drives the drive gear 9 to rotate. The rotation of the drive gear 9 drives the driven gear 10 to rotate.

[0031] A driven shaft 5 is fixedly mounted on the surface of the drive assembly 4. A striking assembly 6 is fixedly sleeved on the surface of the driven shaft 5. The striking assembly 6 includes a hammer head 7, which rotates with the driven shaft 5 and strikes the surface of the filling tube 2. The striking assembly 6 also includes a fixing ring 11 and a connecting rope 12. The fixing ring 11 is fixedly sleeved on the surface of the driven shaft 5, and the connecting rope 12 is fixedly mounted on the surface of the fixing ring 11. The hammer head is fixedly mounted on the other end of the connecting rope 12. There are two sets of striking assemblies 6 corresponding to the driven shaft 5. The two sets of striking assemblies 6 are evenly distributed on the surface of the driven shaft 5. There are three sets of connecting ropes 12. The three sets of connecting ropes 12 are arranged in a ring array with the center of the fixing ring 11 as the array center. The number and position of the hammer head match the number and position of the connecting rope 12.

[0032] In practice, the rotation of the driven gear 10 drives the driven shaft 5 to rotate, which in turn drives the striking assembly 6 to rotate. The rotation of the striking assembly 6, in turn, drives the connecting rope 12 to rotate via the rotating fixed ring 11. The rotation of the connecting rope 12 drives the striking head to rotate. The connecting rope 12 is a nylon rope. The striking head is made of a suitable material, such as hard plastic or a solid rubber ball. This achieves the purpose of striking while reducing the noise generated by striking. The three sets of striking heads rotate and continuously strike the filling tube 2, causing the filling tube 2 to vibrate. The vibration of the filling tube 2 causes the down that is statically attracted to the inner wall of the tube to fall off and follow along. During the filling process, it is discharged along with other down, avoiding adsorption on the inner wall of the tube and affecting the next filling, as well as avoiding accumulation and blockage.

[0033] Example 2 refer to Figures 1-8In this embodiment, the interior of the down filling tube 2 is provided with an annular groove 13, and a rotating ring 14 is rotatably installed inside the annular groove 13. Two sets of disturbance blades 15 are distributed in an annular array on the inner wall of the rotating ring 14. A rotating gear 16 is fixedly sleeved on the side of the rotating ring 14. The rotating gear 16 meshes with the driven gear 10. A protective cover 17 is fixedly installed on the surface of the down filling tube 2 at the locations corresponding to the drive gear 9, the transmission gear, and the driven gear 10.

[0034] In specific implementation, when the driven gear 10 rotates, it drives the rotating gear 16 to rotate synchronously. The rotation of the rotating gear 16 drives the rotating ring 14 to rotate on the inner wall of the filling tube 2. Rotary sealing rings are fixedly installed at both ends of the rotating ring 14. In order to prevent down from entering the gaps, the rotating ring 14 drives the internal disturbance leaf 15 to rotate. The rotation of the disturbance leaf 15 agitates and disperses the knotted down in the filling tube 2, so as to avoid the knots affecting the filling weight and quality, improve the dispersion and achieve uniform filling. Here, the protective cover 17 covers the surface of the drive gear 9, transmission gear and driven gear 10 to protect them, prevent the down that escapes from affecting their operation, and improve the stability of the drive gear 9 and driven gear 10. The driven shaft 5 is rotatably mounted on the protective cover 17 through the bearing to position the driven shaft 5.

[0035] Example 3 refer to Figures 1-8 In this embodiment, a support base is fixedly installed on the top of the placement plate 3 at the port of the down filling tube 2. A slapping plate 23 is rotatably installed on the support base. A through groove 18 is opened on the side of the slapping plate 23. A support frame 19 is fixedly installed on the top of the placement plate 3 near the support base. A reduction motor 20 is fixedly installed on the inner side of the support frame 19. A rotating disk 21 is fixedly installed on the output shaft of the reduction motor 20. A driving rod 22 is fixedly installed on the surface of the rotating disk 21 near the outermost part. The driving rod 22 is movably inserted into the inside of the through groove 18.

[0036] In specific implementation, the shape of the through groove 18 is as follows: Figure 8As shown, the geared motor 20 is also powered by the municipal power supply system. The switch of the geared motor 20 is the same as the switch of the drive motor 8. When the switch is turned on, the geared motor 20 will start. When filling down, the product opening is placed on the surface of the down filling tube 2, and then the existing equipment inside the down filling tank 1 is started to perform the down filling operation. When filling down, the product is located between the patting plate 23 and the placement plate 3. After the down enters the product through the down filling tube 2, the product is filled with down and gas and puffs up. Then the geared motor 20 rotates and drives the rotating disk 21 to rotate. The rotation of the rotating disk 21 will cause the driving rod 22 to rotate around the center of the rotating disk 21. The rotation of the driving rod 22 in the through groove 18 will drive the patting plate 23 to swing back and forth around the connection between the patting plate 23 and the support seat. The patting plate 23 swings back and forth and will pat the down product that has just been filled with down, so that the down inside the down product is dispersed, which is convenient for subsequent processing and manufacturing.

[0037] Example 4 refer to Figures 1-8 In this embodiment, there are two sets of support seats, beating plates 23, rotating disks 21, and driving rods 22. The two sets of support seats and beating plates 23 are symmetrically arranged about the reduction motor 20 as the axis of symmetry. The symmetrically arranged beating plates 23 beat the down products that have just been filled with down. Here, the two sets of beating plates 23 are rotatably installed on the top of the two sets of support seats near one end. At this time, there is a gap between the beating plates 23 and the placement plate 3. The gap is used to place the products to be filled with down. When filling with down, the reduction motor 20 is started. When the geared motor 20 starts, it drives two sets of drive rods 22 and rotating disks 21 to be arranged in a circular array with the geared motor 20 as the array center. The geared motor 20 is a dual-spindle motor. The two sets of rotating disks 21 are symmetrically fixed at both ends of the output shaft of the geared motor 20. This arrangement is to make the two beating plates 23 beat in a staggered manner. That is, when one beating plate 23 beats, the other beating plate 23 is raised, and when the other beating plate 23 beats, the first beating plate 23 is raised. This effectively beats the down evenly.

[0038] In practice, the dual spindle motors synchronously drive two sets of rotating disks 21 to rotate. The rotation of the two sets of rotating disks 21 drives the rotating rods 22 to rotate. Since the two rotating rods 22 are arranged in a circular array, when one rotating rod 22 rotates and drives the beating plate 23 to beat through the through slot 18, the other rotating rod 22 drives the other beating plate 23 to lift through the through slot 18 without beating. When the beating plate 23 is lifted, the other beating plate 23 falls and beats the surface of the down product, achieving the purpose of alternating beating, further improving the beating effect, and avoiding the need for subsequent dispersing work after the down filling is knotted.

[0039] The working principle of this invention is: In operation, the present invention first activates both the drive motor 8 and the reduction motor 20 simultaneously via a switch. The drive motor 8 drives the drive gear 9 to rotate, which meshes with the driven gear 10, causing the driven shaft 5 to rotate. The fixing ring 11, which is fixedly sleeved on the surface of the driven shaft 5, rotates accordingly, thereby driving the hammer head 7, connected by the connecting rope 12, to rotate and continuously strike the outer wall of the filling tube 2. This causes the filling tube 2 to vibrate, shaking off the down feathers that are electrostatically attracted to the tube wall. At the same time, the driven gear 10 meshes with the rotating gear 16 during rotation, driving the rotating ring 14 to rotate in the annular groove 13 inside the filling tube 2. This causes the disturbance blade 15, which is fixedly installed on the inner wall of the rotating ring 14, to rotate, thus affecting the down feathers passing through the filling tube 2. Active agitation and dispersion are performed to prevent down from clumping. After the down is filled into the product placed between the placement plate 3 and the beating plate 23 through the down filling tube 2, the reduction motor 20 starts and drives the rotating disk 21 to rotate. This causes the driving rod 22, which is fixed on the surface of the rotating disk 21, to move in the through groove 18 on the side of the beating plate 23, driving the beating plate 23 to swing back and forth around the support base. Since the reduction motor 20 is a dual-spindle motor and the two sets of beating plates 23 are symmetrically arranged, the two sets of beating plates 23 form an alternating beating action, continuously beating the product that has just been filled with down, so that the down is evenly distributed inside the product. Finally, the down dispersion treatment is achieved throughout the entire process from pipe vibration and internal disturbance to external beating, ensuring that the down filling quality is uniform and stable.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
