DETAILED DESCRIPTION

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] Reference below Figure 1-Figure 6 A vibration packaging device for pillow production according to an embodiment of the present invention is described. The vibration packaging device for pillow production is used in conjunction with a down filling device 9. The filling device 9 has a nozzle 91. The nozzle 91 is used in conjunction with a pillowcase 8. When processing the pillow, in order to facilitate the processing of the pillow, an opening can be reserved at the end of the pillowcase 8 and at the middle position so that the pillowcase 8 can be mounted on the nozzle 91.

[0024] like Figure 1 , Figure 2 As shown, the vibrating packaging device for pillow production includes: a frame 1, a clamping mechanism 2, a movable cover 3, and a driving mechanism 4. The clamping mechanism 2 is arranged on the frame 1, and the clamping mechanism 2 is used to clamp the end of the pillowcase 8 on the nozzle 91 of the filling device 9. The movable cover 3 is arranged on one side of the clamping mechanism 2, and the two ends of the movable cover 3 along the first direction are penetrated, and the first direction is the length direction of the pillowcase 8, and the pillowcase 8 is arranged in the movable cover 3. The driving mechanism 4 is connected to one side of the movable cover 3, and the driving mechanism 4 is used to drive the movable cover 3 to reciprocate along the second direction to vibrate the pillowcase 8, and the second direction is perpendicular to the first direction.

[0025] In an embodiment of the present invention, the clamping mechanism 2 is mounted on the frame 1, and one end of the pillowcase 8 is fixed on the nozzle 91 of the filling device 9. This ensures that during the filling process, the position of the pillowcase 8 is stable and will not slide or fall off. After the pillowcase 8 is clamped and fixed, the filling device 9 starts to fill the antibacterial down into the pillowcase 8, and the movable cover 3 is driven to reciprocate by the driving mechanism 4. Since the end position of the pillowcase 8 connected to the nozzle 91 is fixed, and the pillowcase 8 is located in the movable cover 3, the pillowcase 8 can be shaken by the movable cover 3, and then the down in the pillowcase 8 can be loosened, and the down can be smoothly and evenly filled into the pillowcase 8. When the pillowcase 8 is filled to a predetermined amount, the driving mechanism 4 stops working, the clamping mechanism 2 is released, and the filled pillow can be moved out of the production line to enter the next processing step.

[0026] In some specific examples, the first direction is the direction in which the down is conveyed, that is, the length direction of the pillowcase 8. By pouring the down from one end of the pillowcase 8, it is possible to facilitate the down to be quickly filled into the pillowcase 8.

[0027] Reference Figure 1 , Figure 2 According to some embodiments of the present invention, the cross section of the movable cover 3 is elliptical. When the pillowcase 8 is not filled with down, it is placed in the movable cover 3 with a gap between it and the inner top surface of the movable cover 3, and the length of the movable cover 3 is greater than the length of the pillowcase 8. The unique vibration mode generated by the elliptical movable cover 3 can make the down more evenly distributed inside the pillowcase 8, avoiding local over-density or sparseness.

[0028] Reference Figure 1 , Figure 2 According to some embodiments of the present invention, the movable cover 3 includes an upper cover body 31 and a lower cover body 32 which are hinged to each other on one side, and the upper cover body 31 and the lower cover body 32 are detachably connected on the other side by a connecting piece 33. Since the upper cover body 31 and the lower cover body 32 are hinged, the movable cover 3 can be opened conveniently, thereby facilitating the placement of the pillowcase 8 in the movable cover 3 and the removal of the pillow filled with down. Exemplarily, the connecting piece 33 can be a buckle.

[0029] Reference Figure 3 , Figure 4According to some embodiments of the present invention, the driving mechanism 4 includes: a mounting frame 41, a main shaft 42, a turntable 43, a driving rod 44, and a driving motor 45. The mounting frame 41 is arranged on the frame 1. The main shaft 42 is rotatably connected to the mounting frame 41 and extends along the first direction. The turntable 43 is arranged on the main shaft 42 and is arranged concentrically with the main shaft 42. One end of the driving rod 44 is hinged to the eccentric part of the turntable 43, and the other end of the driving rod 44 is hinged to one side of the movable cover 3. The driving motor 45 is arranged on the frame 1 and connected to one end of the main shaft 42. When the driving motor 45 is started, the main shaft 42 is driven to rotate, and the turntable 43 located on the main shaft 42 rotates. As the turntable 43 rotates, the driving rod 44 will reciprocate, thereby driving the movable cover 3 to reciprocate along the second direction (a direction perpendicular to the first direction), so that the down and pillowcase 8 in the movable cover 3 can be uniformly distributed by vibration while being filled.

[0030] In some specific examples, two drive rods 44 are provided, and four turntables 43 are provided. Two turntables 43 form a group, and a group of turntables 43 are arranged at intervals along the axial direction of the main shaft 42. A drive rod 44 is provided between a group of turntables 43, and the ends of the drive rod 44 are hinged to the eccentric parts of the group of turntables 43. The two drive rods 44 are respectively close to the two ends of the main shaft 42, and the other ends of the two drive rods 44 are respectively hinged to the positions close to the two ends of the movable cover 3, which can provide uniform pulling force and thrust force to the movable cover 3, so that the movable cover 3 is more stable when reciprocating. Specifically, the drive rod 44 is hinged to one side of the lower cover body 32.

[0031] Reference Figure 2 According to some embodiments of the present invention, a plurality of rollers 34 are disposed at the bottom of the movable cover 3 , a guide rail 11 extending along the second direction is disposed on the frame 1 , and the rollers 34 are in rolling cooperation with the guide rail 11 .

[0032] Specifically, two groups of guide rails 11 are arranged at intervals, and four rollers 34 are arranged at the bottom of the movable cover 3 . Two rollers 34 form a group, and each group of rollers 34 cooperates with one guide rail 11 , further improving the stability of the movement of the movable cover 3 .

[0033] Reference Figure 2-Figure 4 According to some embodiments of the present invention, suction mechanisms 5 are provided on the opposite sides of the upper cover body 31 and the lower cover body 32, and the two suction mechanisms 5 are used to adsorb the upper surface and the lower surface of the pillowcase 8 respectively.

[0034] As the suction mechanisms 5 are activated, they generate adsorption forces on the upper and lower surfaces of the pillowcase 8, respectively. This adsorption force ensures that the pillowcase 8 remains stable during the filling process, preventing it from moving or wrinkling inside the movable cover 3. After the pillowcase 8 is firmly adsorbed and fixed by the upper and lower suction mechanisms 5, the down begins to be filled into the pillowcase 8 through the filling device 9. Since the pillowcase 8 is stably fixed, the down can be more evenly distributed in the pillowcase 8. At the same time, the driving mechanism 4 drives the movable cover 3 to reciprocate in the second direction, and the down in the movable cover 3 is vibrated, which further promotes the uniform distribution and looseness of the down.

[0035] Reference Figure 2-Figure 4 According to some embodiments of the present invention, the suction mechanism 5 includes: a suction pipe assembly 51, a suction head 52, a collection pipe 53, and a suction fan 54. The suction pipe assembly 51 is arranged on the surface of the movable cover 3. A plurality of suction heads 52 are arranged on the opposite sides of the upper cover body 31 and the lower cover body 32; the plurality of suction heads 52 are all connected to the suction pipe assembly 51. The collection pipe 53 is connected to the suction pipe assembly 51, and the collection pipe 53 is a telescopic pipe. The collection pipe 53 is connected to the air inlet of the suction fan 54.

[0036] As the suction fan 54 works, the suction head 52 continuously adsorbs the upper and lower surfaces of the pillowcase 8. In this way, the pillowcase 8 can be firmly fixed in a predetermined position during the entire filling process, maintaining tension and preventing displacement or wrinkles. The pillowcase 8 is fixed by a stable suction force, ensuring that the pillowcase 8 does not move during the filling process, thereby making the down distribution more uniform and improving the quality of the final product.

[0037] In some specific examples, the suction head 52 is a columnar structure, one end of the suction head 52 is fixed to the inner top surface or the inner bottom surface of the movable cover 3, and the other end of the suction head 52 passes through the movable cover 3 and is connected to the suction pipe assembly 51. A plurality of ventilation holes are opened on the circumferential surface of the suction head 52, and the ventilation holes are connected to the suction pipe assembly 51. By opening holes on the circumferential surface of the suction head 52, it is not easy to block the ventilation holes when the pillowcase 8 is sucked.

[0038] Reference Figure 2-Figure 4According to some embodiments of the present invention, the suction duct assembly 51 includes: a first duct 511, a second duct 512, a first straight duct 513, a second straight duct 514, a first arc duct 515, and a second arc duct 516. The upper cover 31 and the lower cover 32 are both provided with a plurality of first ducts 511 extending in the second direction. A plurality of first ducts 511 are arranged at intervals along the first direction, and each first duct 511 is connected to a plurality of suction heads 52. The plurality of first ducts 511 located on the upper cover 31 are all connected to one second duct 512, and the plurality of first ducts 511 located on the lower cover 32 are all connected to another second duct 512, and the second duct 512 is extended in the first direction. The first straight duct 513 is connected to one second duct 512 and is arranged in the second direction. The second straight duct 514 is connected to another second duct 512 and is arranged in the second direction. One end of the first arc duct 515 is connected to the other end of the first straight duct 513. One end of the second arc tube 516 is connected to the other end of the second straight tube 514, the upper cover body 31 and the lower cover body 32 are connected by a hinge shaft, the centers of the first arc tube 515 and the second arc tube 516 are both located on the axis of the hinge shaft, one end of the first arc tube 515 is inserted into the second arc tube 516 and slidably cooperates with the second arc tube 516, and one end of the collection tube 53 is connected to one side of the second arc tube 516. When the suction fan 54 is started, a continuous suction force is generated through the collection tube 53, the second arc tube 516, the first arc tube 515, the first straight tube 513, the second straight tube 514, the second air duct 512 and the first air duct 511 to reach each suction head 52, thereby adsorbing the pillowcase 8.

[0039] One end of the first arc tube 515 is inserted into the second arc tube 516 and slidably cooperates with the second arc tube 516 to adapt to the movement of the movable cover 3. Moreover, when the movable cover 3 is opened to put in the pillowcase 8 or take out the pillow, the upper cover body 31 is flipped to one side to open the movable cover 3. When opening the movable cover 3, the first arc tube 515 and the second arc tube 516 can guide the flipping of the upper cover body 31 so that the upper cover body 31 can be stably opened.

[0040] In some specific examples, the collecting pipe 53 includes a main pipe 531 and a sub-pipe 532, both of which are square pipes, and one end of the sub-pipe 532 is inserted into the main pipe 531, the sub-pipe 532 and the main pipe 531 are slidably matched, one end of the main pipe 531 is connected to the suction fan 54, and the other end of the sub-pipe 532 is connected to one side of the second arc pipe 516, so that the collecting pipe 53 can adapt to the reciprocating motion of the movable cover 3 along the second direction. When the upper cover body 31 is closed on the lower cover body 32, the arc structure formed by the first arc pipe 515 and the second arc pipe 516 is parallel to the edge of the ellipse of the movable cover 3, and the connection between the first arc pipe 515 and the second arc pipe 516 is spaced from the side wall of the movable cover 3. The lower end of the first arc pipe 515 is higher than the upper surface of the collecting pipe 53, and the upper end of the second arc pipe 516 is higher than the lower surface of the upper cover body 31, so that the wind in the suction pipe assembly 51 can be smoothly conducted.

[0041] In some other examples, an inclined bracket 6 is fixedly mounted on the frame 1, the bracket 6 is located on one side of the movable cover 3, and two brackets 6 are arranged at intervals along the first direction, the bracket 6 is inclined from bottom to top toward the upper side close to the movable cover 3, and a magnet 61 is arranged on the side of the bracket 6 close to the movable cover 3, and an iron block 35 magnetically attracted to the magnet 61 is fixed on the outer surface of the upper cover body 31. When it is necessary to open the upper cover body 31, the upper cover body 31 is flipped toward the side close to the bracket 6 by unfastening the connector 33. At this time, the magnet 61 is attracted to the iron block 35 to fix the upper cover body 31, thereby facilitating the placement of the pillowcase 8 or the removal of the pillow. Specifically, the angle between the lower surface of the bracket 6 and the upper surface of the frame 1 is 60°.

[0042] Reference Figure 2 , Figure 3 According to some embodiments of the present invention, two clamping mechanisms 2 are provided, and the two clamping mechanisms 2 are used to clamp the two ends of the pillowcase 8 respectively.

[0043] By providing two clamping mechanisms 2 and clamping the two ends of the pillowcase 8 respectively, the pillowcase 8 can be stably fixed on the frame 1, which is convenient for filling with down.

The positioning spring 255 is sleeved on the positioning rod 252, and the two ends of the positioning spring 255 are respectively connected to the mounting seat 251 and the positioning block 253. The positioning block 253 is inserted into the positioning hole 246 by the action of the positioning spring 255. When the pull-out rod 242 is pushed toward the direction close to the pillowcase 8, the positioning block 253 is inserted into the positioning hole 246, so that the pull-out rod 242 cannot move. When the pull-out rod 242 is pulled to slide in the direction away from the pillowcase 8, the positioning block 253 overcomes the elastic force of the positioning spring 255 and shrinks to the side away from the pull-out rod 242 under the action of the inclined surface. When the positioning block 253 is aligned with the adjacent positioning hole 246, the positioning block 253 can be inserted into the adjacent positioning hole 246 under the action of the positioning spring 255 to position the pull-out rod 242. When the pull-out rod 242 needs to be slid toward the side away from the pillowcase 8, the positioning plate 254 can be pulled so that the positioning rod 252 overcomes the elastic force of the positioning spring 255 and slides toward the side away from the pull-out rod 242, and the positioning block 253 disengages from the positioning hole 246, so that the pull-out rod 242 can be flexibly pulled to move along the guide sleeve 241.

[0049] Reference Figure 2 , Figure 3 According to some embodiments of the present invention, a suction nozzle 7 is provided on the frame 1, and the other end of the pillowcase 8 is formed with an opening that is sleeved on the suction nozzle 7. Another clamping mechanism 2 is used to clamp the pillowcase 8 on the suction nozzle 7. The other end of the suction nozzle 7 is connected to a ventilation pipe 71, and the ventilation pipe 71 is connected to the collecting pipe 53.

[0050] Specifically, one end of the ventilation pipe 71 is connected to the main pipe 531 , and the movable cover 3 will not interfere with the ventilation pipe 71 when reciprocating.

[0051] When the pillowcase 8 is firmly fixed by the suction nozzle 7 and the clamping mechanism 2, the filling device 9 starts to fill the pillowcase 8 with down. The other end of the pillowcase 8 is connected to the collecting pipe 53 through the ventilation pipe 71. The suction fan 54 is used to generate negative pressure on the other end of the pillowcase 8, so that the nozzle 91 blows air to one end of the pillowcase 8 and the suction nozzle 7 sucks air to the other end of the pillowcase 8, which helps to quickly fill the pillowcase 8 with down. At the same time, the movable cover 3 moves according to a predetermined reciprocating mode to promote the uniform distribution of the down in the pillowcase 8.
