Description

Technical Field

[0001] This invention relates to the field of pillow filling technology, and more specifically to a pillow filling device that can eliminate static electricity. Background Technology

[0002] In the mass production process of pillow cores, cotton fillings generally adopt a positive pressure pneumatic conveying filling process. First, the pillowcase opening is accurately positioned and fixed on the tooling fixture of the filling device. High-speed, high-pressure airflow is used to directly inflate and fully expand the inner cavity of the pillowcase. Then, the fluffy cotton fibers, which have undergone opening, combing, and dust removal pretreatment, are evenly injected into the inner cavity of the pillowcase through a quantitative conveying air pipe with the airflow. After quantitative filling is completed, compaction, shaping, and sealing are performed to ensure the fullness, density uniformity, and production efficiency of the pillow core filling.

[0003] Cotton fibers are prone to static electricity and clumping during pretreatment. Although existing pillow filling devices mostly use metal grounding for anti-static treatment during the injection stage, they cannot completely eliminate static electricity. In addition, after the cotton fibers enter the pillowcase, they move with the airflow and rub against each other, which will continue to generate static electricity. Ultimately, this results in uneven distribution of cotton fibers in the pillowcase and insufficient filling.

[0004] Currently, some technical solutions involve adding a vibration mechanism to the filling device, using the bottom plate of the operating table to pat the pillow core, thereby breaking up cotton fibers that have clumped due to static electricity and improving the fluffiness of the filling. However, this solution still has significant drawbacks: it is difficult to achieve zoned and irregular patting operations. Because the entire bottom plate vibrates synchronously, in the same direction, and at the same frequency, cotton fibers tend to slide along the vibration direction, leading to localized accumulation, missing cotton at the edges and corners, and even more severe delamination with repeated vibration. The overall filling quality of the pillow core still needs improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a pillow filling device that can eliminate static electricity, enabling zoned and irregular patting operations, and further eliminating clumping caused by static electricity by combining with metal grounding, thereby improving the quality of pillow filling.

This reduces equipment investment costs and avoids problems such as inadequate patting and pillowcase scratches caused by mismatched specifications. It balances filling effect and ease of operation, allowing the solution to flexibly handle the filling operations of various pillow cores and improve the practicality and applicability of the solution.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] like Figures 1 to 11 As shown: A pillow filling device capable of eliminating static electricity includes an operating table 1, with a support plate 11 fixedly connected to the inner wall of the operating table 1. It also includes a first loosening component 2 and a driving component 3. The first loosening component 2 includes multiple sets of top plates 20, multiple rotating shafts 21, and multiple sets of cams 22. The multiple sets of top plates 20 are arrayed on the top of the operating table 1. A slide rod 23 is fixedly connected to the bottom of the top plate 20. The slide rod 23 passes through the top wall of the operating table 1 and is slidably connected to it. The multiple rotating shafts 21 are equidistantly distributed inside the operating table 1 and are rotatably connected to the inner wall of the operating table 1. The multiple sets of cams 22 are coaxially connected to the multiple rotating shafts 21 respectively. The cams 22 are used to push the slide rods 23 to slide vertically. The driving component 3 is installed on the operating table 1 and is used to drive the rotating shafts 21 to rotate.

[0036] During pillow filling, the open end of the pillowcase is first fitted onto the feed pipe 53 and secured, then placed on the operating table 1. The sealing and filling assembly 5 then drives the cover plate 50 to rotate horizontally to prevent the pillow from bouncing, and cotton fibers are injected into the pillow through the feed pipe 53. Subsequently, the drive assembly 3 is activated, causing multiple rotating shafts 21 to rotate simultaneously. Multiple cams 22 on the rotating shafts 21 drive the corresponding top plates 20, causing them to slide vertically back and forth rapidly under the push of the slide rod 23, thus achieving a bottom-up patting effect on the pillow. Furthermore, the segmented arrangement of the multiple top plates 20 allows each plate to pat different parts of the pillow, improving the looseness and uniformity of the filling, and further eliminating the problem of clumping caused by static electricity.

[0037] like Figures 1 to 8 As shown: To further enhance the loosening effect by patting multiple top plates 20 at different times, the top of the operating table 1 is provided with multiple grooves 10 for accommodating the top plates 20. Each set of cams 22 has multiple cams, and the long axis 13 ends of the multiple cams 22 point in different directions. Both sides of the cams 22 have concave structures. The bottom of the slide rod 23 is fixedly connected to a U-shaped plate 24. The inner wall of the U-shaped plate 24 is rotatably connected to a first roller 25 and a pair of second rollers 26. The two second rollers 26 are symmetrically arranged at both ends of the U-shaped plate 24. The bottom of the first roller 25 abuts against the top of the cam 22, and the second roller 26 abuts against the inner wall of the cam 22. When all the first rollers 25 abut against the short axis ends of the cams 22, all the top plates 20 are located in the grooves 10.

[0038] When cam 22 rotates, its edge contacts the first roller 25 and the second roller 26, causing the U-shaped plate 24 to move up and down with the rotation of cam 22. This further drives the slide rod 23 and the top plate 20 to slide back and forth, realizing the patting operation. At the same time, the arrangement of the first roller 25 and the second roller 26 reduces friction and extends the service life. Since the long axis 13 ends of the multiple cams 22 on a single rotating shaft 21 point in different directions, the timing of the reciprocating movement of the multiple top plates 20 in each group is also different, further improving the irregularity of the patting, thus making the filling effect more uniform. When the rotating shaft 21 rotates to a specific angle, all cams 22 rotate so that their short axis ends point upwards, causing all top plates 20 to move into the bottom groove 10. At this time, the top of the top plate 20 is flush with the operating table 1, which can maintain the flatness of the operating table 1 and facilitate the operation of clamping and placing the pillow core.

[0039] like Figures 4 to 8 As shown: The drive assembly 3 includes a motor 30, a drive shaft 31, a plurality of first bevel gears 32 and a plurality of second bevel gears 33. The bottom of the motor 30 is fixedly connected to the support plate 11. The output shaft of the motor 30 is coaxially connected to the drive shaft 31. The drive shaft 31 is coaxially connected to the first bevel gears 32. The second bevel gears 33 are coaxially connected to one end of the rotating shaft 21. The first bevel gears 32 and the second bevel gears 33 mesh with each other.

[0040] When the motor 30 is powered on, its output shaft drives the drive shaft 31 to rotate, which in turn drives multiple first bevel gears 32 to rotate. Through the meshing transmission between the first bevel gears 32 and the second bevel gears 33, multiple rotating shafts 21 can be driven to rotate simultaneously, thereby synchronously driving all the cams 22 to rotate and pushing the top plate 20 to perform the patting operation.

[0041] like Figures 4 to 10 As shown: The present invention also includes a plurality of second loosening components 12 and a plurality of linkage components 4. The plurality of second loosening components 12 are equidistantly distributed on the support plate 11. The second loosening components 12 have the same structure as the first loosening components 2. The number of top plates 20 of the second loosening components is half the number of top plates 20 of the first loosening components 2. The linkage components 4 are installed on the support plate 11. The linkage components 4 are used to make the rotating shaft 21 of the first loosening components 2 rotate synchronously with the rotating shaft 21 of the second loosening components 12.

[0042] The linkage assembly 4 includes a pair of round rods 40, a sliding sleeve 41, an insert plate 42, a rack 43, and a spur gear 44. The two round rods 40 are coaxially connected to the rotating shaft 21 of the first loosening assembly 2 and the rotating shaft 21 of the second loosening assembly 12, respectively. Each of the two round rods 40 has a slot 400 at one of its opposite ends. The sliding sleeve 41 is slidably connected to the outer periphery of the round rods 40. The inner wall of the sliding sleeve 41 is fixedly connected to the insert plate 42. One end of the insert plate 42 is slidably connected to one of the slots 400, and the other end of the insert plate 42 is inserted into the other slot 400. The rack 43 is fixedly connected to the bottom of the sliding sleeve 41. The rack 43 meshes with the spur gear 44. The spur gear 44 is rotatably mounted on the support plate 11.

[0043] The present invention also includes multiple long shafts 13, multiple turntables 14, multiple locking blocks 15, multiple first telescopic rods 16, and multiple first springs 17. The multiple long shafts 13 pass through the spur gears 44 of multiple sets of linkage components 4 and are coaxially connected with them. The long shafts 13 pass through the inner wall of the operating table 1 and are rotatably connected with it. The turntables 14 are coaxially connected with the long shafts 13. The locking blocks 15 mesh with the spur gears 44. The bottom of the locking blocks 15 is fixedly connected to the telescopic end of the first telescopic rods 16. The bottom of the first telescopic rods 16 is fixedly connected to the support plate 11. The first springs 17 are sleeved on the periphery of the first telescopic rods 16. One end of the first springs 17 is fixedly connected to the locking blocks 15, and the other end of the first springs 17 is fixedly connected to the support plate 11.

[0044] By adding a second loosening component 12, the number of top plates 20 is increased, expanding the patting area and thus adapting to the filling needs of pillow cores of different sizes. Simultaneously, the linkage component 4 controls whether the second loosening component 12 works synchronously with the first loosening component 2. When the second loosening component 12 needs to work, it is driven to work synchronously with the first loosening component 2 via the linkage component 4, eliminating the need for an additional power source. When the second loosening component 12 does not need to work, its connection with the first loosening component 2 is disconnected via the linkage component 4, preventing the top plate 20 from moving and scratching the pillowcase.

[0045] Rotating the turntable 14 causes the long shaft 13 to simultaneously drive multiple spur gears 44 to rotate. Through the meshing transmission between the spur gears 44 and the rack 43, the sliding sleeves 41 of multiple linkage components 4 are driven to slide horizontally around the round rod 40, so that one end of the insert plate 42 is inserted into the slot 400. At this time, both ends of the insert plate 42 are respectively engaged with the slots 400 on the two round rods 40. When one of the round rods 40 rotates, the insert plate 42 can synchronously drive the other round rod 40 to rotate, so that the rotating shaft 21 of the first loosening component 2 and the rotating shaft 21 of the second loosening component 12 rotate synchronously to achieve linkage. Conversely, simply rotating the turntable 14 in the opposite direction can disconnect the linkage effect.

[0046] Multiple turntables 14 are located between the first loosening component 2 and the second loosening component 12, as well as between two adjacent second loosening components 12. Rotating one turntable 14 corresponds to whether one second loosening component 12 is working. Simultaneously, when the turntable 14 is rotated, the engagement of the locking block 15 and the spur gear 44 increases the sliding resistance of the sliding sleeve 41, preventing automatic slippage during linkage operation and ensuring the stability of the linkage. The rotation of the spur gear 44 pushes the locking block 15 up and down, causing the first spring 17 to repeatedly compress and rebound, enabling the sliding sleeve 41 to move. Furthermore, the first telescopic rod 16 prevents the first spring 17 from bending, improving stability.

[0047] like Figures 1 to 11 As shown: The present invention also includes an edge sealing and filling component 5, which includes a cover plate 50, an edge pressing strip 51, an edge pressing table 52, a material conveying pipe 53, and an air duct 54. The cover plate 50 is hinged to one side of the operating table 1. One end of the cover plate 50 is fixedly connected to the edge pressing strip 51. The edge pressing table 52 is fixedly connected to one end of the operating table 1. The middle parts of the edge pressing strip 51 and the middle parts of the edge pressing table 52 are both concave and can be combined to form a ring structure. The material conveying pipe 53 is vertically movable and installed on the operating table 1. One end of the material conveying pipe 53 passes through the middle of the edge pressing table 52, and the other end of the material conveying pipe 53 is connected to the air duct 54. A grounding wire 530 is fixedly connected to one side of the material conveying pipe 53.

[0048] The edge sealing and filling assembly 5 also includes a fixing ring 531, a pair of second telescopic rods 55 and a pair of second springs 56. The fixing ring 531 is fixedly connected to the material conveying pipe 53. The two second telescopic rods 55 are symmetrically arranged on both sides of the fixing ring 531. The bottom of the second telescopic rod 55 is fixedly connected to the operating table 1. The telescopic end of the second telescopic rod 55 is fixedly connected to the fixing ring 531. The second spring 56 is sleeved around the second telescopic rod 55. One end of the second spring 56 is fixedly connected to the fixing ring 531 and the other end of the second spring 56 is fixedly connected to the operating table 1.

[0049] The edge sealing and filling assembly 5 also includes a hydraulic cylinder 57. The bottom of the hydraulic cylinder 57 is rotatably connected to the operating table 1. A support shaft 500 and a pair of swing arms 501 are fixedly connected to one side of the cover plate 50. The support shaft 500 is rotatably connected to the telescopic end of the hydraulic cylinder 57, and the bottom of the swing arms 501 is rotatably connected to the operating table 1.

[0050] The top of the operating table 1 has a sunken structure. The edge sealing and filling assembly 5 also includes a pair of sprockets 58 and a support rod 59. The bottom of the support rod 59 is rotatably connected to the end of the operating table 1 away from the pressing table 52. The top of the support rod 59 is in close contact with the bottom of the cover plate 50. One of the sprockets 58 is coaxially connected to the bottom of the swing arm 501, and the other sprocket 58 is coaxially connected to the bottom of the support rod 59. The two sprockets 58 are driven by a chain.

[0051] The opening of the pillow core is fitted around the conveyor pipe 53, with its bottom aligned with the pressing table 52. Then, the hydraulic cylinder 57 is activated, its telescopic end pushing the support shaft 500 and causing it to rotate around it. Simultaneously, the bottom of the hydraulic cylinder 57 rotates on one side of the operating table 1, causing the cover plate 50 to rotate from a vertical position around the bottom of the swing arm 501 to a horizontal position. At this point, the cover plate 50 is positioned above the pillow core, preventing it from jumping. The pressing strip 51 follows the cover plate 50 in its rotation, squeezing the pillow core from above, and working with the pressing table 52 to hold the opening of the pillow core in place. During this process, the conveyor belt is squeezed downwards, and the fixing ring 531 moves accordingly, causing the second telescopic rod 55 to shorten and the second spring 56 to compress. Simultaneously, the swing arm 501 drives one of the sprockets 58 to rotate. Through the chain transmission between the two sprockets 58, the support rod 59 rotates to a vertical position and is aligned with the bottom of the cover plate 50, preventing the cover plate 50 from tilting and shaking due to a lack of support at one corner.

[0052] Subsequently, high-speed airflow, along with cotton fibers, is injected into the feeding pipe 53 via the air duct 54. The feeding pipe 53 is made of conductive metal. As the cotton fibers pass through the feeding pipe 53 and enter the pillow core, they come into contact with the inner wall of the feeding pipe 53, causing their charge to be discharged by the feeding pipe 53 and conducted along the grounding wire 530, thereby initially eliminating static electricity. After filling is completed, the cover plate 50 flips back to its original position. At this time, the second spring 56 rebounds and pushes the feeding pipe 53 upward, making it easier to remove the pillow core.

[0053] In practical use, the static-eliminating pillow filling device of this invention first fixes the open end of the pillow core onto the conductive metal feeding pipe 53 and places it on the operating table 1. Then, the top plate 20 of the drive plate of the edge-sealing filling component 5 is flipped to a horizontal position, and the hydraulic cylinder 57 is activated to flip the cover plate 50 to a horizontal position. This, together with the edge-pressing table 52 and the edge-pressing strip 51, firmly clamps the open end of the pillow core, preventing the pillow core from jumping during filling. At the same time, the support rod 59 supports the cover plate 50 through the sprocket 58 and chain drive, preventing the cover plate 50 from tilting and shaking, and ensuring clamping stability. Next, high-speed airflow and cotton fibers are injected into the feeding pipe 53 through the air duct 54. After the cotton fibers come into contact with the inner wall of the feeding pipe 53, static electricity is discharged and conducted, initially preventing the cotton fibers from clumping.

[0054] Simultaneously, cotton fibers are injected into the pillow core, and the motor 30 is started. Multiple rotating shafts 21 are driven to rotate via bevel gear transmission, causing the cam 22, slide rod 23, and top plate 20 to slide back and forth, patting the pillow core in different areas. Combined with the different directions of the cam 22, irregular patting is achieved, effectively improving the looseness of the cotton fibers and the uniformity of the filling, further eliminating the problem of static clumping. When the rotating shaft 21 rotates to a specific angle, the top plate 20 retracts into the groove 10, flush with the operating table 1, ensuring the operating table 1 is flat. If different specifications of pillow cores need to be accommodated, rotating the turntable 14 enables the first and second loosening components 12 to be linked via gear transmission, expanding the patting area without an additional power source. The locking block 15 and the spur gear 44 cooperate to ensure stable linkage. Reversing the rotation of the turntable 14 can disconnect the linkage, preventing scratches on the pillowcase. After filling is complete, the cover plate 50 is reset, and the feed pipe 53 moves upward, facilitating the removal of the pillow core. Throughout the process, all components work together, balancing filling efficiency, quality, and equipment lifespan.
