Description

Technical Field

[0001] This utility model relates to the field of down pillow filling technology, specifically an automatic down pillow fluffing machine. Background Technology

[0002] After filling, down pillows undergo a fluffing process called "patting" to restore their loft, evenly distribute the filling, remove clumps and impurities, and improve breathability. After filling, the down may be compacted, clumped, or unevenly piled, affecting the pillow's comfort and performance. Patting helps the down disperse, restoring its original elasticity and fluffiness, thus enhancing the pillow's softness and resilience for a better sleep experience. Furthermore, patting helps distribute the down evenly within the pillow core, preventing overly dense or porous areas and ensuring the overall stability and comfort of the pillow's structure. During the process, staff will gently pat the pillow on a clean, flat work surface using their palms or a special patting stick, spreading the down from the center outwards repeatedly until the desired fluffiness is achieved. While patting, the pillow should also be turned over to ensure that every corner is fully treated. However, manual patting is a labor-intensive task that takes a long time and requires a lot of physical strength. The number of times and the force of patting each pillow must be controlled by the worker. The operation consumes a lot of human resources and makes it difficult to achieve efficient production. Especially when the production line is expanded or the order volume increases, relying on manual patting is difficult to meet the production capacity demand and can easily become a production bottleneck. Furthermore, the different operating habits, strength, and skill levels of different workers result in differences in the fluffiness of each pillow, making it difficult to guarantee the uniformity of the fluffiness of down pillow products. Utility Model Content

[0003] The purpose of this invention is to provide an automatic down pillow fluffing machine. The down pillow to be fluffed is transported by a rotary drive unit and a belt conveyor. During the translation, the upper drive shaft, the patting plate, and the linkage reciprocating patting structure receive power from the rotary drive unit through a gear reduction transmission structure. This allows the down pillow to be continuously patted by multiple patting plates and the linkage reciprocating patting structure during the translation, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic down pillow fluffing machine, comprising a frame, a belt conveyor installed inside the frame for horizontally transferring down pillow workpieces, and a rotary drive unit installed on one side of the bottom of the frame for driving the belt conveyor. L-shaped baffles are fixed on both the front and rear inner walls of the frame. Several equally spaced upper drive shafts are rotatably installed between two L-shaped baffles in the X-axis horizontal direction. A beater is fixed to one end of each upper drive shaft. A linkage-type reciprocating beater structure is installed between two L-shaped baffles on one side of the upper drive shaft. A primary drive transmission structure for power transmission is installed between the linkage-type reciprocating beater structure and the upper drive shaft. A secondary drive transmission structure for maintaining power connection is installed between the multiple upper drive shafts in the X-axis horizontal direction. A gear reduction transmission structure for power connection is installed between one of the linkage-type reciprocating beater structures and the belt conveyor. A motor controller electrically connected to the input end of the rotary drive unit is installed on one side of the frame surface.

[0005] Preferably, the rotary drive unit consists of a motor, a synchronous pulley, and a synchronous belt. The motor is mounted on one side of the bottom of the frame via a hanger. The synchronous pulley is mounted on the output shaft end of the motor and the end of one of the belt rollers of the belt conveyor. The synchronous belt is fitted onto the two synchronous pulleys. The input end of the motor is electrically connected to the output end of the motor controller.

[0006] Preferably, each of the two L-shaped baffles has a support fixed on its outer wall, and a vertical bearing seat is bolted to the top of the support. The upper drive shaft is rotatably mounted between the two vertical bearing seats in the same Y-axis direction.

[0007] Preferably, the linkage-type reciprocating striking structure includes driven shafts rotatably mounted on both sides of the top of the frame via bearing seats, a turntable fixed at one end of the driven shafts, and a connecting rod hinged to one end of the turntable surface. The linkage-type reciprocating striking structure also includes a column fixed to one side of the top of the support and convex plates slidably mounted on the two columns. The top of the connecting rod is hinged to one side of the outer wall of the convex plate. A U-shaped striking frame is fixed to one side of the bottom of the convex plate. The primary drive transmission structure is set on the opposite ends of the two driven shafts, and the driven shafts drive the upper drive shaft to rotate through the primary drive transmission structure.

[0008] Preferably, the gear reduction transmission structure includes a primary gear mounted on the end of another belt roller of the belt conveyor, a secondary gear shaft and a tertiary gear shaft rotatably mounted on one side of the frame surface, and a reduction gear ring fixed on the outer circumference of the turntable, wherein the primary gear, the secondary gear shaft, the tertiary gear shaft and the tertiary gear shaft mesh sequentially.

[0009] Preferably, the convex plate and the U-shaped racket frame are both made of hard plastic components.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This automatic down pillow fluffing machine is equipped with a rotating drive unit, a belt conveyor, two L-shaped baffles on the left and right, a gear reduction transmission structure, multiple upper drive shafts in the conveying direction, a beater, and a linkage reciprocating beating structure, etc., working together. The down pillow to be fluffed is transported by the rotating drive unit and the belt conveyor. During the translation, the upper drive shafts, beaters, and linkage reciprocating beating structure receive power from the rotating drive unit through the gear reduction transmission structure, so that the down pillow is continuously beaten by multiple beaters and linkage reciprocating beating structures during the translation. The rotating drive unit, as the power source, can provide stable and continuous power output, providing a solid power foundation for the entire fluffing system. The belt conveyor smoothly transports the down pillow to the beater. The patting process ensures the pillow remains consistently positioned during movement, providing a good foundation for subsequent patting operations. The gear reduction transmission structure and two-stage drive transmission structure effectively reduce the rotational speed of the drive unit, converting high-speed power into a low-speed, high-torque output suitable for patting actions. This allows each pat to be performed at a slower but more powerful rhythm, ensuring sufficient and even force in each pat. It also reduces uneven patting caused by unstable speed, ensuring each down pillow undergoes thorough and continuous patting, improving production continuity and efficiency. Secondly, the collaboration of multiple patting plates and a linkage-type reciprocating patting structure allows the down pillow to be continuously patted at multiple points during movement, more comprehensively affecting all parts of the pillow, effectively breaking up the compacted down, restoring its loft, and improving the uniformity of down distribution.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Example 1, by Figures 1 to 5 The present invention includes a frame 1, a belt conveyor 2 for horizontally transferring down pillow workpieces installed inside the frame 1, and a rotary drive unit 3 for driving the belt conveyor 2 installed on one side of the bottom of the frame 1. L-shaped baffles 4 are fixed on the front and rear inner walls of the frame 1. Several equally spaced upper drive shafts 5 are rotatably installed between two L-shaped baffles 4 in the horizontal direction of the X-axis. A beater 6 is fixed to one end of the surface of the upper drive shaft 5. A linkage reciprocating beater structure 7 is installed between two L-shaped baffles 4 on one side of the upper drive shaft 5. A primary drive transmission structure 11 for power transmission is installed between the linkage reciprocating beater structure 7 and the upper drive shaft 5. A secondary drive transmission structure 9 for maintaining power connection is installed between the multiple upper drive shafts 5 in the horizontal direction of the X-axis. The secondary drive transmission structure 9 is used to transmit the rotational power of the upper drive shaft 5 to the next linkage reciprocating beater structure 7, ensuring that the multiple linkage reciprocating beater structures 7 in the horizontal direction all operate synchronously.

[0019] A gear reduction transmission structure 8 for power connection is installed between one of the linkage reciprocating beat structure 7 and the belt conveyor 2, and a motor controller 10 electrically connected to the input end of the rotary drive unit 3 is installed on one side of the frame 1 surface.

[0020] The rotary drive unit 3 consists of a motor, a synchronous pulley, and a synchronous belt. The motor is mounted on one side of the bottom of the frame 1 via a hanger. The synchronous pulley is mounted on the output shaft end of the motor and the end of one of the belt rollers of the belt conveyor 2. The synchronous belt is fitted onto the two synchronous pulleys. The input end of the motor is electrically connected to the output end of the motor controller 10. The motor in the rotary drive unit 3 works according to the direction, speed, angle, and response time set by the motor controller 10. Then, the motor drives one of the belt rollers of the belt conveyor 2 to rotate through the synchronous pulley and the synchronous belt, thereby driving the belt conveyor 2 to perform working translation.

[0021] Two L-shaped baffles 4 are fixed with support bases 401 on their outer walls that are far apart. Vertical bearing seats 402 are bolted to the top of the support bases 401. The upper drive shaft 5 is rotatably installed between the two vertical bearing seats 402 in the same Y-axis direction.

[0022] Example 2, based on Example 1, is... Figure 4 and Figure 5 The connecting rod reciprocating striking structure 7 includes a driven shaft 701 rotatably mounted on both sides of the top of the frame 1 via a bearing seat, a turntable 702 fixed at one end of the driven shaft 701, and a connecting rod 704 hinged to one end of the surface of the turntable 702. The connecting rod reciprocating striking structure 7 also includes a column 403 fixed to one side of the top of the support 401 and a convex plate 703 slidably mounted on the two columns 403. The top of the connecting rod 704 is hinged to one side of the outer wall of the convex plate 703. When the convex plate 703 and the U-shaped striking frame 705 reciprocate and slide, the column 403 guides the convex plate 703 to slide, ensuring the stability of the movement of the convex plate 703 and the U-shaped striking frame 705.

[0023] A U-shaped racket frame 705 is fixed on one side of the bottom end of the convex plate 703. The primary drive transmission structure 11 is set on the opposite ends of the two driven shafts 701. The driven shafts 701 drive the upper drive shaft 5 to rotate through the primary drive transmission structure 11. Both the convex plate 703 and the U-shaped racket frame 705 are made of hard plastic components.

[0024] The gear reduction transmission structure 8 includes a primary gear 801 mounted on the end of another belt roller of the belt conveyor 2, a secondary gear shaft 802 and a tertiary gear shaft 803 rotatably mounted on one side of the frame 1, and a reduction gear ring 804 fixed on the outer circumference of the turntable 702. The primary gear 801, the secondary gear shaft 802, and the tertiary gear shaft 803 mesh sequentially. A belt roller of the belt conveyor 2 away from the rotary drive unit 3 drives the secondary gear shaft 802 and the tertiary gear shaft 803 to rotate sequentially through the primary gear 801, so that the linkage reciprocating patting structure 7 near the starting end of the belt conveyor 2 can work. Then, the linkage reciprocating patting structure 7 drives the upper drive shaft 5 and the patting plate 6 to rotate through the primary drive transmission structure 11. At this time, the patting plate 6 rotates around the upper drive shaft 5 and pats the down pillow on the belt surface of the belt conveyor 2.

[0025] The reduction gear ring 804, turntable 702, and driven shaft 701 are driven to rotate by the three-stage gear shaft 803. The rotational motion of the turntable 702 is converted into the vertical reciprocating linear motion of the convex plate 703 and the U-shaped beater 705 through the connecting rod 704. The U-shaped beater 705 continuously beats the down pillow on the belt surface of the belt conveyor 2.

[0026] In this embodiment, the operator first places the down pillow to be processed at the starting position of the belt conveyor 2, ensuring that the pillow is correctly and evenly positioned between the two L-shaped baffles 4. The rotational speed of the rotary drive unit 3 is then set by the motor controller 10. This rotational speed is directly proportional to the feeding speed of the belt conveyor 2, the rotational speed of the upper drive shaft 5, and the beating frequency of the patting plate 6 and the linkage-type reciprocating beating structure 7. After the rotary drive unit 3 starts working, it provides a stable power source to the belt conveyor 2, causing the conveyor 2 to slowly move the down pillow along the conveying direction towards the beating area of ​​the patting plate 6 and the linkage-type reciprocating beating structure 7. During this process, the two L-shaped baffles 4 serve a positioning and guiding function, ensuring that the down pillow remains within the predetermined beating range, providing precise positioning for subsequent beating operations. The process begins as the down pillow reaches the beating area of ​​the first patting plate 6 and the linkage reciprocating beating structure 7. The gear reduction transmission structure 8 drives one of the linkage reciprocating beating structures 7 and the upper drive shaft 5 to begin operation. The patting plate 6 on the upper drive shaft 5 continuously contacts the down pillow, and the linkage reciprocating beating structure 7 reciprocates vertically, beating the down pillow until it passes multiple patting plates 6 and linkage reciprocating beating structures 7 along the conveying direction. No manual intervention is required during the beating process; simply ensure the device is operating normally. The patting plate 6 and linkage reciprocating beating structure 7 will continuously beat the down pillow at multiple points with a preset frequency and force to break up clumps in the down, restore its loft, and ensure even distribution of the down. After a certain period of beating, the down pillow continues to move along the conveyor line of the belt conveyor 2, entering the next process or packaging stage.
