DETAILED DESCRIPTION

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0038] The present invention will be further described below in conjunction with the embodiments.

[0039] Example:

[0040] Please refer to the attached Figure 1-8 This solution proposes a down quilt fast filling device, 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, and a quilt cover fixing mechanism 4 is installed on the down filling bed 2. When in use, the quilt cover to be filled with down is placed on the surface of the down filling bed 2, and the four corners of the quilt cover are fixed by the quilt 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 quilt cover, the down can be filled into the quilt cover.

[0041] Specifically, a movable mechanism 3 is installed on the surface of the down-filled bed 2, and the quilt cover fixing mechanism 4 includes four groups of fixing units installed on the movable mechanism 3. The distribution positions of the four groups of fixing units can be adjusted through the movable mechanism 3, so that the four groups of fixing units can clamp and fix quilt covers of different sizes, thereby increasing the applicability of the device.

[0042] The mobile mechanism 3 includes a slide rail 301, a reciprocating screw rod 302, a slider 303 and a motor 304. The reciprocating screw rod 302 is installed 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 connected to the reciprocating screw rod 302 in a transmission connection. The motor 304 is configured as two groups of motors 304 that are adapted to be installed on the surface of the reciprocating screw rod 302, and the sliding directions of the two groups of motors 304 on the reciprocating screw rod 302 are opposite. The motor 304 is used to install the workpiece to be moved. When in use, the motor 304 is turned on to drive the reciprocating screw rod 302 to rotate, and the motor 304 is controlled to slide linearly on the slide rail 301, so that the position adjustment of the workpiece installed on the motor 304 can be realized. And through the reverse sliding of the two groups of motors 304, the spacing adjustment of the two groups of workpieces installed on the mobile mechanism 3 can be realized.

[0043] The mobile mechanism 3 for installing the quilt cover fixing mechanism 4 is set to three groups, one group of mobile mechanisms 3 is distributed horizontally, and two groups are distributed vertically. The mobile mechanism 3 distributed horizontally includes a slide rail 301 installed on the filling machine 1, and the slide rails 301 in the two groups of mobile mechanisms 3 distributed vertically are respectively installed on the two groups of sliders 303 distributed horizontally. Two groups of fixed units are installed on the two groups of mobile mechanisms 3 distributed vertically, and the two groups of fixed units are adaptively installed on the two groups of motors 304 distributed vertically. At the same time, the spacing between the two groups of mobile mechanisms 3 distributed vertically can be adjusted by running the mobile mechanism 3 distributed horizontally, and the size of the two groups of fixed units distributed vertically can be adjusted by running the mobile mechanism 3 distributed vertically. Further, the quilt cover fixing mechanism 4 can form a matrix distribution of different sizes under the coordinated operation of the three groups of mobile mechanisms 3, so as to facilitate the fixing of quilt covers of different lengths and widths, thereby improving the practicality of the device.

[0044] The quilt cover fixing mechanism 4 includes a bottom plate 401 and a fixing plate 402 installed on the motor 304, the bottom plate 401 is located below the fixing plate 402, an electric telescopic rod 403 is installed above the fixing plate 402, and a clamping plate 404 is provided at the lower end of the piston rod of the electric telescopic rod 403. When the quilt cover fixing mechanism 4 needs to fix the quilt cover, one corner of the quilt cover is placed on the surface of the bottom plate 401 and spread out flat, and the clamping plate 404 is driven to slide down by the electric telescopic rod 403 and pressed on the quilt cover, so that the quilt cover can be clamped and fixed between the bottom plate 401 and the clamping plate 404. The four corners of the quilt cover are placed on the four fixing units for clamping in turn, so that the quilt cover can be installed on the quilt cover fixing mechanism 4. And through the operation of the three groups of moving mechanisms 3, the spacing of the four groups of fixing units can be adjusted, so that the four groups of fixing units tighten the four corners of the quilt cover, and then the quilt cover is spread flat on the surface of the down-filled bed 2, which is convenient for the subsequent filling process, and the down can be evenly distributed in the quilt cover.

[0045] More specifically, a group of vertically distributed moving mechanisms 3 are also installed on the lower surface of the filling machine 1, and the filling mechanism 6 is adaptively installed on the moving mechanism 3. By covering the operation of the group of moving mechanisms 3, the filling mechanism 6 can be linearly slid above the filling bed 2. After the quilt cover is laid flat on the surface of the filling bed 2, the zipper opening of the quilt cover is facing the side of the filling mechanism 6. Through the operation of the moving mechanism 3, the quilt cover fixing mechanism 4 can be controlled to be inserted into the quilt cover for down filling, and the filling mechanism 6 is driven to slide during the filling process, so that the filling mechanism 6 moves in the quilt cover, which is convenient for filling different positions in the quilt cover.

[0046] The filling mechanism 6 includes a filling tube 601 mounted on the motor 304. The front end surface of the filling tube 601 is provided with uniformly distributed nozzles 602. The rear end of the filling tube 601 is connected to the filling machine 1 through the connecting hose 5. When in use, the down in the filling machine 1 can be input into the filling tube 601 through the connecting hose 5, and under the action of wind, the down is ejected from the nozzle 602 at the front end of the filling tube 601, so that the down can be filled into the quilt cover through the filling tube 601.

[0047] The filling tube 601 is set as a "T"-shaped structure, and two groups of symmetrically distributed movable tubes 603 are inserted at the front end of the filling tube 601. The surfaces of the two groups of movable tubes 603 are also provided with uniformly distributed nozzles 602, and one end of the movable tube 603 inserted inside the filling tube 601 is open, so that the down inside the filling tube 601 will also 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 pipe 604 is installed inside the filling tube 601, and a sliding rod 606 is connected to the surface of the movable tube 603. The sliding rod 606 is inserted into the air pipe 604 in a matching manner. At the same time, a pressure pump 605 is installed at the rear end of the filling tube 601, and the pressure pump 605 and the air pipe 604 are connected. By adjusting the pressure in the air pipe 604 through the pressure pump 605, the sliding rod 606 can be controlled to slide in the air pipe 604, and the movable tube 603 can be further controlled to extend and retract at the front end of the filling tube 601 to adjust the extension length of the movable tube 603.

[0048] When the quilt cover has not yet been laid on the surface of the down-filled bed 2, the filling mechanism 6 is moved to one side of the down-filled bed 2 by the moving mechanism 3, so that the quilt cover will not be blocked when it is spread out by the quilt cover fixing mechanism 4. After the quilt cover is spread out, the filling mechanism 6 is driven to move to one side of the quilt cover by the moving mechanism 3, and the zipper of the quilt cover is manually opened, so that the filling tube 601 can be inserted into the quilt cover, which is convenient for subsequent filling. During the insertion of the filling mechanism 6, the movable tube 603 is retracted into the filling tube 601 to prevent the zipper from reciprocating into the small zipper.

[0049] 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 meets the minimum quilt cover width, and further, after the filling tube 601 is inserted into the quilt cover, it just matches the width of the quilt cover. When the quilt cover is filled with down, the front position of the filling tube 601 will be uniformly filled with down at the same time. By extending the movable tube 603 in the filling tube 601, the overall filling length can be adjusted, thereby adapting to quilt covers of different widths, thereby improving the applicability of the device.

[0050] The difference is that a quilt pressing mechanism 7 is installed above the filling mechanism 6. When the moving mechanism 3 drives the filling mechanism 6 to move, the quilt pressing mechanism 7 will be controlled to move synchronously. The quilt pressing mechanism 7 includes a mounting frame 701 mounted on the surface of the filling tube 601. The front end of the mounting frame 701 is rotatably connected to a central pressing roller 702, and the lower surface of the central pressing roller 702 contacts the surface of the filling bed 2. When the filling tube 601 is inserted into the quilt cover, the central pressing roller 702 will press on the upper surface of the quilt cover. And when the filling tube 601 slides from one end of the quilt cover to the zipper opening to fill the quilt, the central pressing roller 702 will synchronously press on the surface of the quilt cover and slide toward the zipper opening. Furthermore, when the filling tube 601 moves during the filling process, the central pressure roller 702 will just roll over the filled position of the quilt cover, separating the filled position from the unfilled position in the quilt cover, thereby preventing the filling tube 601 from blowing away the down in the filled position during the continuous filling process, resulting in uneven distribution of the down in the quilt cover.

[0051] 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 quilt cover when dividing it to prevent wind from passing through.

[0052] The surfaces of both sides of the mounting frame 701 are fixedly connected with fixed rods 703, the surfaces of the fixed rods 703 are rotatably connected with rotating blocks 704, and the surfaces of the rotating blocks 704 are rotatably connected with side pressure rollers 705. When the width of the quilt cover is greater than the length of the central pressure roller 702, the quilt cover that exceeds the length distribution of the central pressure roller 702 can be rolled by the side pressure rollers 705, thereby ensuring that the space inside the quilt cover is effectively separated. In addition, the surface of the rotating block 704 is provided with threaded holes, and the threaded holes are provided with limit bolts 706 for limiting and fixing. By rotating the rotating block 704 on the fixed rod 703, the relative angles of the side pressure rollers 705 and the central pressure roller 702 can be adjusted, and then the rolling lengths of the central pressure rollers 702 and the side pressure rollers 705 can be adapted to the width of the quilt cover, and at the same time, the quilt cover fixing mechanism 4 will not be interfered with during the movement, thereby ensuring the stability of the operation of the device.

[0053] The surface of the down-filled bed 2 is provided with a collecting groove 8. When the quilt cover is spread out on the surface of the down-filled bed 2, the zipper opening of the quilt cover is aligned with the collecting groove 8. When the down-filling mechanism 6 moves the down inside the quilt cover and slides out from the zipper opening, the down-filling mechanism 6 stops filling the down, and the quilt pressing mechanism 7 continues to roll the quilt cover surface until the quilt pressing mechanism 7 slides away from the quilt cover surface. Since the zipper opening of the quilt cover is open, the quilt pressing mechanism 7 will squeeze out part of the quilt cover during the sliding process, and the quilt pressing mechanism 7 will align the zipper opening of the quilt cover through the collecting groove 8, so that the discharged down will fall into the collecting groove 8 and be collected, thereby avoiding the waste of down.

[0054] A method for using a down quilt quick filling device comprises the following steps:

[0055] Step 1: Place the four corners of the quilt cover on four fixing units respectively, and clamp and fix the four corners of the quilt cover by the fixing units;

[0056] Step 2: Start one set of transversely distributed moving mechanisms 3 and two sets of vertically distributed moving mechanisms 3 to operate, and adjust the transverse and vertical spacings between the four sets of fixed units through the three sets of moving mechanisms 3, so that the four corners of the quilt cover are tightened and laid flat on the surface of the filling bed 2, and the zipper opening of the quilt cover faces the side of the filling mechanism 6;

[0057] Step 3: start another set of vertically distributed moving mechanisms 3 to operate, control the filling mechanism 6 to insert into the quilt cover from the zipper opening of the quilt cover, and move to the deepest end in the quilt cover;

[0058] Step 4: Start the filling machine 1, transport the down to the filling mechanism 6 through the connecting hose 5, and fill the quilt cover with down. During the filling process, the filling mechanism 6 slides toward the outside of the quilt cover, and the pressing mechanism 7 presses on the surface of the quilt cover synchronously to separate the filled and unfilled spaces;

[0059] Step 5: After the filling mechanism 6 slides out from the zipper opening of the quilt cover, it stops outputting down until the quilt pressing mechanism 7 slides away from the surface of the quilt cover, thereby achieving complete filling of the quilt cover with down.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements 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.

The method for using the down quilt quick filling device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Place the four corners of the quilt cover on four fixing units respectively, and clamp and fix the four corners of the quilt cover by the fixing units; Step 2: Start a set of transversely distributed moving mechanisms (3) and two sets of vertically distributed moving mechanisms (3) to operate, and adjust the transverse spacing and vertical spacing between the four sets of fixed units through the three sets of moving mechanisms (3), so that the four corners of the quilt cover are tightened and laid flat on the surface of the filling bed (2), and the zipper opening of the quilt cover is facing the side of the filling mechanism (6); Step 3: another set of vertically distributed moving mechanisms (3) is started to operate, and the filling mechanism (6) is controlled to be inserted into the quilt cover from the zipper opening of the quilt cover, and moved to the deepest end of the quilt cover; Step 4: Start the filling machine (1) to run, transport the down to the filling mechanism (6) through the connecting hose (5), and fill the quilt cover with down. During the filling process, the filling mechanism (6) slides toward the outside of the quilt cover, and the pressing mechanism (7) presses on the surface of the quilt cover synchronously to separate the filled and unfilled spaces; Step 5: After the filling mechanism (6) slides out from the zipper opening of the quilt cover, it stops outputting down until the quilt pressing mechanism (7) slides away from the surface of the quilt cover, thereby achieving complete filling of the quilt cover with down.
