Description

Technical Field

[0001] This invention relates to the field of down filling device technology, specifically to a rapid down filling device for down comforters and its usage method. Background Technology

[0002] Down comforters are widely popular due to their lightweight and warmth. In current down comforter manufacturing, filling typically involves using a down filling machine to insert down into the comforter cover. During operation, the machine uses a fan to blow the down into the cover. However, the airflow during operation cannot guarantee an even distribution of down within the comforter cover, necessitating continuous repositioning of the filling tube. As the filling tube is moved, the continuous airflow from the tube affects down in other areas, causing the already filled down to disperse and resulting in uneven down distribution. Summary of the Invention

[0003] Technical problems to be solved In view of the above-mentioned shortcomings of the existing technology, the present invention provides a down comforter rapid filling device and its usage method, which can solve the problem that the wind force sprayed by the down filling machine during the filling process causes the down in other parts of the comforter to be blown away and the down to be unevenly distributed.

[0004] Technical solution To achieve the above objectives, the present invention provides the following technical solution: A rapid down filling device for a down comforter includes a down filling machine and a down filling bed. The down filling bed is equipped with a duvet cover fixing mechanism and a down filling mechanism. The down filling mechanism is connected to the down filling machine via a connecting hose. A first moving mechanism is installed on the down filling bed. The duvet cover fixing mechanism includes four sets of fixing units mounted on the first moving mechanism. These four sets of fixing units are used to fix the four corners of the duvet cover. The first moving mechanism drives the four sets of fixing units to slide and tighten the four corners of the duvet cover, causing the duvet cover to lie flat on the surface of the down filling bed. A second moving mechanism is also installed on the down filling bed to drive the down filling mechanism to slide linearly and insert into the duvet cover for down filling. A pressing mechanism is installed above the down filling mechanism to press against the surface of the duvet cover, separating the filled and unfilled spaces, as the down filling mechanism slides outward and fills the duvet cover.

[0005] Furthermore, both the first and second moving mechanisms are moving mechanisms, each including a slide rail, a reciprocating lead screw, a slider, and a motor. The reciprocating lead screw is mounted on the slide rail and is distributed in parallel. The motor is connected to the slide rail, and the output shaft of the motor is connected to the reciprocating lead screw via a transmission. The slider is configured as two sets of compatible sliders mounted on the surface of the reciprocating lead screw, with the two sets of sliders sliding in opposite directions on the reciprocating lead screw. The slider is used to mount the workpiece to be moved.

[0006] Furthermore, the first moving mechanism for installing the duvet cover fixing mechanism is configured as three groups, one group of the first moving mechanism is distributed horizontally, and two groups are distributed vertically. The two groups of the first moving mechanism distributed vertically are respectively installed on the two groups of sliders distributed horizontally, and two groups of fixing units are installed on the two groups of sliders distributed vertically.

[0007] Furthermore, the duvet cover fixing mechanism includes a base plate and a fixing plate mounted on a motor. The base plate is located below the fixing plate, and an electric telescopic rod is mounted above the fixing plate. The lower end of the piston rod of the electric telescopic rod is provided with a clamping plate.

[0008] Furthermore, the down filling mechanism is mounted on a set of vertically distributed second moving mechanisms below the down filling machine. The down filling mechanism includes a down filling tube mounted on a slider. The front end surface of the down filling tube is provided with uniformly distributed nozzles. The connecting hose is mounted on the rear end of the down filling tube.

[0009] Furthermore, the filling tube is configured with a "T" shaped structure, and two sets of symmetrically distributed movable tubes are inserted at the front end of the filling tube. The surfaces of the two sets of movable tubes are also provided with evenly distributed nozzles. The end of the movable tube inserted into the filling tube is open. An air tube is installed inside the filling tube. A sliding rod is connected to the surface of the movable tube. The sliding rod is inserted into the air tube in a matching manner. A pressure pump is installed at the rear end of the filling tube. The pressure pump is used to adjust the pressure inside the air tube.

[0010] Furthermore, the pressing mechanism includes a mounting frame installed on the surface of the filling tube, with a central pressure roller rotatably connected to the front end of the mounting frame, and the lower surface of the central pressure roller abutting against the surface of the filling bed.

[0011] Furthermore, the length of the central pressure roller is equal to the length of the front end of the filling tube, and a fixing rod is fixedly connected to both sides of the mounting frame. A rotating block is rotatably connected to the surface of the fixing rod, and a side pressure roller is rotatably connected to the surface of the rotating block. A threaded hole is provided on the surface of the rotating block, and a limit bolt is installed in the threaded hole.

[0012] Furthermore, the surface of the down filling bed is provided with a collection groove.

[0013] A method for using a down comforter quick filling device includes the following steps: Step 1: Place the four corners of the quilt onto the four fixing units respectively, and use the fixing units to clamp and fix the four corners of the quilt. Step 2: Activate one set of horizontally distributed first moving mechanisms and two sets of vertically distributed first moving mechanisms. Adjust the horizontal and vertical spacing between the four fixed units through the three sets of first moving mechanisms so that the four corners of the duvet cover are tightened and laid flat on the down filling bed surface, and the zipper opening of the duvet cover faces the down filling mechanism side. Step 3: Activate the operation of another set of vertically distributed second moving mechanisms, control the down filling mechanism to insert into the duvet cover from the zipper opening, and move to the deepest end inside the duvet cover; Step 4: Turn on the down filling machine and transport the down to the filling mechanism through the connecting hose to fill the duvet cover. During the filling process, the filling mechanism slides outward from the duvet cover, and the pressing mechanism presses on the duvet cover surface at the same time to separate the filled and unfilled spaces. Step 5: After the down filling mechanism slides out of the zipper opening of the duvet cover, it stops outputting down until the pressing mechanism slides off the surface of the duvet cover, thus achieving complete down filling inside the duvet cover.

[0014] Beneficial effects The technical solution provided by this invention has the following advantages compared with the known prior art: This invention, through its duvet cover fixing mechanism and its structural design, allows the duvet cover to be clamped and fixed at its four corners by four fixing units before filling. The position of the four fixing units can then be adjusted to tighten the four corners of the duvet cover, thereby making the duvet cover lay flat on the surface of the filling bed. This facilitates the even distribution of down in the duvet cover during the subsequent filling process. At the same time, the duvet cover fixing mechanism can be used to fill duvet covers of different sizes, improving the applicability of this device.

[0015] This solution, through the structural design of the down filling mechanism, allows the filling range to be adjusted according to the width of the duvet cover when the filling mechanism is inserted into the duvet cover. Furthermore, during the filling process, the filling mechanism can completely, evenly, and fully fill the filling area in front of it, ensuring the uniform distribution of down within the duvet cover during filling.

[0016] This solution uses a pressure mechanism to ensure that when the filling mechanism moves outward during the filling process, the pressure roller will press down on the already filled area of ​​the duvet cover. This separates the filled and unfilled areas inside the duvet cover, thus preventing the filling tube from blowing away the down in the already filled area during the continuous filling process, which would otherwise result in uneven distribution of down inside the duvet cover.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0021] The present invention will be further described below with reference to embodiments.

[0022] Example: Please refer to the appendix. Figure 1-8 This solution proposes a rapid down filling device for comforters, including a down filling machine 1 and a down filling bed 2. The down filling machine 1 and the down filling mechanism 6 are connected. A comforter cover fixing mechanism 4 is installed on the down filling bed 2. In use, the comforter cover to be filled is placed on the surface of the down filling bed 2, and the four corners of the comforter cover are fixed by the comforter cover fixing mechanism 4. Then, down is added to the down filling machine 1, and the down filling machine 1 is turned on. By inserting the down filling mechanism 6 inside the comforter cover, the down can be filled into the comforter cover.

[0023] Specifically, the surface of the down-filled bed 2 is equipped with a first moving mechanism, and the duvet cover fixing mechanism 4 includes four sets of fixing units installed on the first moving mechanism. The distribution position of the four sets of fixing units can be adjusted through the first moving mechanism, so that the four sets of fixing units can clamp and fix duvet covers of different sizes, thereby increasing the applicability of the device.

[0024] The device also includes a second moving mechanism. The first and second moving mechanisms have the same structure, both being moving mechanism 3. Moving mechanism 3 includes a slide rail 301, a reciprocating lead screw 302, a slider 303, and a motor 304. The reciprocating lead screw 302 is mounted on the slide rail 301 and is distributed in parallel. The motor 304 is connected to the slide rail 301, and the output shaft of the motor 304 is drively connected to the reciprocating lead screw 302. Two sets of sliders 303 are configured to be fitted onto the surface of the reciprocating lead screw 302, and the two sets of sliders 303 slide in opposite directions on the reciprocating lead screw 302. The sliders 303 are used to mount the workpiece to be moved. In use, the motor 304 is turned on, driving the reciprocating lead screw 302 to rotate and controlling the sliders 303 to slide linearly on the slide rail 301, thus adjusting the position of the workpiece mounted on the sliders 303. Furthermore, by sliding the two sets of sliders 303 in opposite directions, the distance between the two sets of workpieces mounted on the moving mechanism can be adjusted.

[0025] The first moving mechanism for installing the duvet cover fixing mechanism 4 is configured in three groups: one group is horizontally distributed, and two groups are vertically distributed. The horizontally distributed first moving mechanism includes a slide rail 301 mounted on the filling machine 1. The slide rails 301 in the two vertically distributed first moving mechanisms are respectively mounted on the two horizontally distributed sliders 303. Each of the two vertically distributed first moving mechanisms has two sets of fixing units installed, and these fixing units are fitted onto the two vertically distributed sliders 303. Simultaneously, the operation of the horizontally distributed first moving mechanism adjusts the distance between the two vertically distributed first moving mechanisms, and the operation of the vertically distributed first moving mechanism adjusts the size of the two vertically distributed fixing units. Furthermore, with the coordinated operation of the three groups of first moving mechanisms, the four fixing units of the duvet cover fixing mechanism 4 can form a matrix distribution of different sizes, thus facilitating the fixing of duvet covers of different lengths and widths and improving the practicality of the device.

[0026] The duvet cover fixing mechanism 4 includes a base plate 401 and a fixing plate 402 mounted on a slider 303. The base plate 401 is located below the fixing plate 402, and an electric telescopic rod 403 is mounted above the fixing plate 402. A clamping plate 404 is provided at the lower end of the piston rod of the electric telescopic rod 403. When the duvet cover fixing mechanism 4 needs to fix the duvet cover, one corner of the duvet cover is placed on the surface of the base plate 401 and laid flat. The clamping plate 404 is driven to slide down by the electric telescopic rod 403 and presses onto the duvet cover, thus achieving clamping and fixing of the duvet cover between the base plate 401 and the clamping plate 404. By sequentially placing the four corners of the duvet cover on the four fixing units and clamping them, the duvet cover can be installed on the duvet cover fixing mechanism 4. Through the operation of the three sets of first moving mechanisms, the spacing of the four sets of fixing units can be adjusted, so that the four sets of fixing units tighten the four corners of the duvet cover, thereby making the duvet cover lay flat on the surface of the down filling bed 2, which facilitates the even distribution of down in the duvet cover during the subsequent filling process.

[0027] More specifically, a set of vertically distributed second moving mechanisms is also installed on the lower surface of the down filling machine 1. The down filling mechanism 6 is adapted to be installed on the second moving mechanisms. Through the operation of this set of second moving mechanisms, the down filling mechanism 6 can be linearly slid above the down filling bed 2. After the duvet cover is laid flat on the surface of the down filling bed 2, the zipper opening of the duvet cover is facing the side of the down filling mechanism 6. Through the operation of the second moving mechanisms, the down filling mechanism 6 can be controlled to insert into the duvet cover to fill it with down. During the filling process, the down filling mechanism 6 is driven to slide, so that the down filling mechanism 6 moves in the duvet cover, which facilitates the filling of different positions in the duvet cover with down.

[0028] The down filling mechanism 6 includes a down filling tube 601 mounted on a slider 303. The front end of the down filling tube 601 has evenly distributed nozzles 602, and the rear end of the down filling tube 601 is connected to the down filling machine 1 via a connecting hose 5. In use, down from the down filling machine 1 is fed into the down filling tube 601 through the connecting hose 5, and under the action of airflow, it is ejected from the nozzles 602 at the front end of the down filling tube 601, allowing the down to fill the duvet cover.

[0029] The filling tube 601 is designed with a "T" shape. Two sets of symmetrically distributed movable tubes 603 are inserted into the front end of the filling tube 601. The surfaces of the two sets of movable tubes 603 are also provided with evenly distributed nozzles 602. The end of the movable tube 603 inserted inside the filling tube 601 is open, allowing the down inside the filling tube 601 to enter the movable tube 603 under the action of wind and be ejected from the nozzles 602 on the surface of the movable tube 603. An air tube 604 is installed inside the filling tube 601. A slide rod 606 is connected to the surface of the movable tube 603 and is appropriately inserted inside the air tube 604. A pressure pump 605 is installed at the rear end of the filling tube 601 and is connected to the air tube 604. The pressure inside the air tube 604 is adjusted by the pressure pump 605, which controls the sliding rod 606 to slide inside the air tube 604, and further controls the extension and retraction of the movable tube 603 at the front end of the filling tube 601, thus adjusting the extension length of the movable tube 603.

[0030] Before the duvet cover is laid on the surface of the down filling bed 2, the second moving mechanism moves the down filling mechanism 6 to one side of the down filling bed 2, ensuring that the duvet cover is not obstructed when it is laid out flat by the duvet cover fixing mechanism 4. After the duvet cover is laid out flat, the second moving mechanism drives the down filling mechanism 6 to move to one side of the duvet cover, and the zipper of the duvet cover is manually opened, allowing the down filling tube 601 to be inserted into the duvet cover for subsequent down filling. During the insertion of the down filling mechanism 6, the movable tube 603 is retracted into the down filling tube 601 to prevent reciprocating insertion due to the small zipper opening.

[0031] When both sets of movable tubes 603 are retracted into the filling tube 601, the length of the front end of the filling tube 601 matches the minimum width of the duvet cover. This ensures that the filling tube 601, once inserted into the duvet cover, perfectly matches its width. During filling, the front portion of the filling tube 601 is simultaneously and evenly filled with down. The overall filling length can be adjusted by the movable tube 603 extending from the filling tube 601, thus adapting to duvet covers of different widths and sizes, improving the applicability of this device.

[0032] The difference lies in the fact that a pressing mechanism 7 is installed above the filling mechanism 6. When the second moving mechanism drives the filling mechanism 6 to move, it controls the pressing mechanism 7 to move synchronously. The pressing mechanism 7 includes a mounting bracket 701 mounted on the surface of the filling tube 601. A central pressure roller 702 is rotatably connected to the front end of the mounting bracket 701, and the lower surface of the central pressure roller 702 abuts against the surface of the filling bed 2. When the filling tube 601 is inserted into the duvet cover, the central pressure roller 702 presses against the upper surface of the duvet cover. And when the filling tube 601 slides from one end of the duvet cover toward the zipper opening to fill the duvet cover, the central pressure roller 702 simultaneously presses against the surface of the duvet cover and slides toward the zipper opening. Furthermore, when the filling tube 601 moves during the filling process, the central pressure roller 702 will just press down on the filled position of the duvet cover, separating the filled and unfilled positions inside the duvet cover. This prevents the filling tube 601 from blowing away the down in the filled position during the continuous filling process, thus avoiding uneven distribution of down inside the duvet cover.

[0033] It is worth noting that the length of the central pressure roller 702 is equal to the length of the front end of the filling tube 601, which further enables the central pressure roller 702 to completely block the space inside the duvet cover when dividing it, thus preventing wind from passing through.

[0034] Both sides of the mounting frame 701 are fixedly connected to fixing rods 703. Rotating blocks 704 are rotatably connected to the surfaces of the fixing rods 703, and side pressure rollers 705 are rotatably connected to the surfaces of the rotating blocks 704. When the width of the quilt cover is greater than the length of the central pressure roller 702, the side pressure rollers 705 can roll over the quilt cover beyond the length of the central pressure roller 702, thus ensuring effective space division within the quilt cover. Furthermore, the rotating blocks 704 have threaded holes, in which limiting bolts 706 are installed for positioning and fixing. By rotating the rotating blocks 704 on the fixing rods 703, the relative angle between the side pressure rollers 705 and the central pressure roller 702 can be adjusted, allowing the rolling length of the central pressure roller 702 and the side pressure rollers 705 to match the width of the quilt cover. Simultaneously, during movement, there is no interference with the quilt cover fixing mechanism 4, thus ensuring the stability of the device's operation.

[0035] The surface of the down-filled mattress 2 is provided with a collection groove 8. When the duvet cover is laid flat on the surface of the down-filled mattress 2, the zipper opening of the duvet cover is aligned with the collection groove 8. When the down-filling mechanism 6 moves inside the duvet cover to fill down and slides out from the zipper opening, the down-filling mechanism 6 stops filling down, while the pressing mechanism 7 continues to press the surface of the duvet cover until the pressing mechanism 7 slides off the surface of the duvet cover. Since the zipper opening of the duvet cover is in an open state, the pressing mechanism 7 will squeeze out some of the down inside the duvet cover during the sliding process. As the collection groove 8 aligns with the zipper opening of the duvet cover, the discharged down will fall into the collection groove 8 and be collected, thus avoiding waste of down.

[0036] A method for using a down comforter quick filling device includes the following steps: Step 1: Place the four corners of the quilt onto the four fixing units respectively, and use the fixing units to clamp and fix the four corners of the quilt. Step 2: Activate one set of horizontally distributed first moving mechanisms and two sets of vertically distributed first moving mechanisms. Adjust the horizontal and vertical spacing between the four sets of fixed units through the three sets of first moving mechanisms so that the four corners of the duvet cover are tightened and laid flat on the surface of the down filling bed 2, and the zipper opening of the duvet cover faces the down filling mechanism 6. Step 3: Activate the operation of another set of vertically distributed second moving mechanisms, and control the down filling mechanism 6 to insert into the duvet cover from the zipper opening and move to the deepest end inside the duvet cover; Step 4: Turn on the down filling machine 1 and transport the down to the down filling mechanism 6 through the connecting hose 5 to fill the duvet cover. During the filling process, the down filling mechanism 6 slides outward from the duvet cover, and the duvet pressing mechanism 7 presses on the duvet cover surface at the same time to separate the filled and unfilled spaces. Step five: After the down filling mechanism 6 slides out of the zipper opening of the duvet cover, it stops outputting down until the pressing mechanism 7 slides off the surface of the duvet cover, thus achieving complete down filling inside the duvet cover. The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
