[0004] The inventors discovered the following drawbacks in the above content: when quilting the duvet cover is required, a quilting machine is usually used to sew it together, and the duvet cover needs to be fixed between sewing. However, in the prior art, after the duvet cover is fixed, when quilting the other side of the duvet cover is required, the operator needs to disassemble and re-clamp the duvet cover. The steps are too cumbersome, which not only reduces work efficiency but also increases labor costs. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that, after the quilt cover is fixed, when it is necessary to quilt the other side of the quilt cover, the operator needs to disassemble and re-clamp the quilt cover, which is too cumbersome, reduces work efficiency, and increases labor costs.

[0006] To solve the above technical problems, this utility model provides a quilting positioning device for a duvet cover, comprising: a machine frame, a movable frame mounted on the upper surface of the machine frame, a movable rod fixedly connected to the inner side of the movable frame, a quilting assembly mounted on the arc surface of the movable rod, a control panel on one side of the movable frame, a drive mechanism for driving the movable frame inside the machine frame, and a fixing device inside the machine frame, the fixing device comprising two connecting rods, the two connecting rods being movably connected to both sides of the inner wall of the machine frame, and concave frames fixedly connected to the ends of the two connecting rods that are close to each other, the upper surface of the concave frames being threaded... A threaded connection is provided, with a rod head fixedly connected to the top of the screw. A pressure plate is rotatably connected to the end of the screw away from the rod head. The end of the connecting rod away from the concave frame completely penetrates the machine tool frame. Circular grooves are provided on both sides of the machine tool frame corresponding to the positions of the connecting rods. A turntable is fixedly connected to the end of the connecting rod near the circular groove. Two insertion holes are provided on the inner wall of the circular groove. A pin slides through the turntable on the side away from the connecting rod. The pin is slidably connected to the inner wall of one of the insertion holes. An elliptical plate is fixedly connected to the arc surface of the pin. A limit rod is fixedly connected to the side of the turntable away from the connecting rod. The elliptical plate is slidably connected to the limit rod.

[0007] The aforementioned components achieve the following effects: when quilting is required, the quilt cover can be clamped and fixed to ensure that the position of the quilt cover does not change during quilting; and the quilt cover can be rotated and turned over to quilt the other side, thereby saving the step of re-clamping and turning the quilt cover over, and speeding up the work efficiency.

[0008] Preferably, a plurality of rubber strips are fixedly connected to the lower surface of the pressure plate, and the plurality of rubber strips are evenly distributed on the lower surface of the pressure plate.

[0009] The effect achieved by the above components is that when the pressure plate is used to clamp the shell, the rubber strip can increase the friction on the surface of the pressure plate, thus making the fixing effect better.

[0010] Preferably, a spring is fitted onto the arc surface of the pin, and the two ends of the spring are fixedly connected to the elliptical plate and the turntable, respectively.

[0011] The effect achieved by the above components is that when the elliptical plate is used to insert or remove the pin, the spring is stretched, causing the spring to generate elastic force. When the elliptical plate is released, the spring uses its elastic force to automatically insert the pin into the socket.

[0012] Preferably, a handle is fixedly connected to the side of the elliptical plate away from the turntable, and the handle has a "U" shaped cross-section.

[0013] The effect achieved by the above components is that when the elliptical plate needs to be pulled, it can be operated with the help of a handle, making the operation simpler and more convenient.

[0014] Preferably, the inner side of the machine tool frame is provided with a cleaning device, which includes two slide grooves. The two slide grooves are respectively opened on both sides of the inner wall of the machine tool frame. The inner walls of the two slide grooves are fixedly connected to slide rods. The arc surface of the slide rods is movably connected to a connecting cylinder. The arc surface of the connecting cylinder is fixedly connected to a connecting plate. The side of the connecting plate away from the connecting cylinder is fixedly connected to a concave plate. The lower surface of the concave plate is threaded with a lead screw. One end of the lead screw is rotatably connected to the inner side of the concave plate. The lower end of the lead screw is fixedly connected to a knob. The two ends of the lead screw are threaded with opposite directions. The arc surface of the lead screw is threaded with two rectangular plates. Cleaning brushes are installed on the side of the two rectangular plates that are close to each other. The inner walls of the machine tool frame are provided with slots on both sides.

[0015] The effect achieved by the above components is as follows: after the quilted cover is quilted, the cover can be positioned between the two cleaning brushes. The position of the two cleaning brushes can be adjusted so that they contact the top and bottom surfaces of the cover. At this time, the concave plate is pushed to drive the cleaning brushes to clean the quilt cover of impurities such as loose threads.

[0016] Preferably, the knob has a plurality of arc grooves on its arc surface, and the plurality of arc grooves are evenly distributed on the arc surface of the knob.

[0017] The effect achieved by the above components is that when the lead screw needs to be rotated, the knob can be rotated by the arc groove of the knob, which in turn drives the lead screw to rotate, thus preventing slippage when rotating the knob.

[0018] Preferably, a magnetic sheet is fixedly connected to the inner wall of the card slot, and the connecting plate is an iron plate.

[0019] The effect achieved by the above components is as follows: after cleaning the shell, the cleaning brush is moved to the slot, the connecting cylinder is rotated to make the cleaning brush turn to a vertical position and fit against the inner wall of the slot. The magnetic sheet is used to attract the connecting plate, which serves to temporarily store the cleaning brush.

[0020] Compared with related technologies, the quilting positioning device for a duvet cover provided by this utility model has the following beneficial effects:

[0021] By operating the fixing device, when quilting the duvet cover is required, the two ends of the duvet cover can be clamped and fixed in the pressure plate and concave frame with the help of the pressure plate.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 6 The present invention provides a quilting positioning device for a duvet cover, comprising: a machine frame 1, a movable frame 2 mounted on the upper surface of the machine frame 1, a movable rod 3 fixedly connected to the inner side of the movable frame 2, a quilting assembly 4 mounted on the arc surface of the movable rod 3, a control panel 5 provided on one side of the movable frame 2, a drive mechanism for driving the movable frame 2 provided inside the machine frame 1, a fixing device 6 provided inside the machine frame 1, and a cleaning device 7 provided inside the machine frame 1.

[0033] In the embodiments of this utility model, please refer to Figures 1 to 4The fixing device 6 includes two connecting rods 601, which are movably connected to both sides of the inner wall of the machine tool frame 1. A concave frame 602 is fixedly connected to the end of each connecting rod 601 closest to each other. A screw 604 is threaded onto the upper surface of the concave frame 602. A rod head 603 is fixedly connected to the top of the screw 604. A pressure plate 605 is rotatably connected to the end of the screw 604 away from the rod head 603. The end of the connecting rod 601 away from the concave frame 602 completely penetrates the machine tool frame 1. The two sides of the machine tool frame 1 corresponding to the connecting rods 601... A circular groove 610 is provided at the position. A turntable 607 is fixedly connected to one end of the connecting rod 601 near the circular groove 610. Two insertion holes 614 are provided on the inner wall of the circular groove 610. A pin 609 slides through the turntable 607 on the side away from the connecting rod 601. The pin 609 is slidably connected to the inner wall of one of the insertion holes 614. An elliptical plate 612 is fixedly connected to the arc surface of the pin 609. A limiting rod 608 is fixedly connected to the side of the turntable 607 away from the connecting rod 601. The elliptical plate 612 is slidably connected to the limiting rod 608. This design allows the duvet cover to be clamped and fixed when quilting is required, ensuring that the duvet cover does not change position during quilting. It also allows the duvet cover to be rotated and turned over for quilting on the other side, thus saving the step of re-clamping and turning the duvet cover over, and speeding up the work efficiency. Several rubber strips 606 are fixedly connected to the lower surface of the pressure plate 605, and the rubber strips 606 are evenly distributed on the lower surface of the pressure plate 605. This increases the friction of the pressure plate 605 surface when the pressure plate 605 is used to clamp the outer shell, resulting in a better fixing effect. A spring 611 is fitted onto the arc surface of the pin 609, and the two ends of the spring 611 are fixedly connected to the elliptical plate 612 and the turntable 607, respectively. This stretches the spring 611 when the pin 609 is inserted or removed using the elliptical plate 612, causing the spring 611 to generate elastic force. When the elliptical plate 612 is released, the spring 611 uses its elastic force to automatically insert the pin 609 into the insertion hole 614. A handle 613 is fixedly connected to the side of the elliptical plate 612 away from the turntable 607. The handle 613 has a U-shaped cross-section. This achieves the effect that when the elliptical plate 612 needs to be pulled, it can be operated with the help of the handle 613, making the operation simpler and more convenient.

[0034] In the embodiments of this utility model, please refer to Figure 1 , Figure 5 and Figure 6The cleaning device 7 includes two slides 701, which are respectively opened on both sides of the inner wall of the machine tool frame 1. The inner walls of the two slides 701 are fixedly connected to slide rods 702. The arc surface of the slide rods 702 is movably connected to a connecting cylinder 703. The arc surface of the connecting cylinder 703 is fixedly connected to a connecting plate 704. The side of the connecting plate 704 away from the connecting cylinder 703 is fixedly connected to a concave plate 705. The lower surface of the concave plate 705 is threaded with a lead screw 706. One end of the lead screw 706 is rotatably connected to the inner side of the concave plate 705. The lower end of the lead screw 706 is fixedly connected to a knob 707. The two ends of the lead screw 706 are threaded in opposite directions. The arc surface of the lead screw 706 is threaded with two rectangular plates 709. Cleaning brushes 710 are installed on the side of the two rectangular plates 709 that are close to each other. The inner walls of the machine tool frame 1 are provided with slots 711. After the duvet cover is quilted, it can be positioned between two cleaning brushes 710. Adjusting the position of the two cleaning brushes 710 allows them to contact the top and bottom surfaces of the duvet cover. At this point, pushing the concave plate 705 drives the cleaning brushes 710 to clean loose threads and other impurities from the duvet cover. The knob 707 has several arc-shaped grooves 708 evenly distributed on its arc surface. This allows the knob 707 to be rotated using the arc-shaped grooves 708, preventing slippage when rotating the knob 707. A magnetic sheet 712 is fixedly connected to the inner wall of the slot 711, and the connecting plate 704 is made of iron. After cleaning the casing, move the cleaning brush 710 to the slot 711, rotate the connecting cylinder 703 to make the cleaning brush 710 rotate to a vertical position and fit against the inner wall of the slot 711. Use the magnetic sheet 712 to attract the connecting plate 704, which serves to temporarily store the cleaning brush 710.

[0035] The working principle of the quilting positioning device for duvet covers provided by this utility model is as follows: When quilting a duvet cover is required, the duvet cover needs to be fixed. First, the operator places both ends of the duvet cover in two concave frames 602, respectively, below the pressure plate 605. Then, the operator holds the rod head 603 and rotates it. When the rod head 603 is rotated, it will drive the screw 604 to rotate and move downward in the threaded hole of the concave frame 602. As the screw 604 moves downward, it pushes the pressure plate 605 to move downward. When the rubber strip 606 on the lower surface of the pressure plate 605 contacts the duvet cover, it undergoes elastic deformation, which increases the contact area and generates frictional resistance to achieve clamping and fixing of the duvet cover. When quilting is required on the other side of the duvet cover, the operator holds handle 613 and pulls it away from the machine tool frame 1. Handle 613 pulls the elliptical plate 612 to move. As the elliptical plate 612 moves, it slides along the arc surface of the limiting rod 608. The elliptical plate 612 causes the pin 609 to disengage from the insertion hole 614 on the inner wall of the circular groove 610, thus releasing the lock. At this time, the spring 611 is stretched, generating a spring force opposite to the direction of movement of the elliptical plate 612. Then, the turntable 607 is rotated. The turntable 607 drives the concave frame 602 and the entire clamped duvet cover to rotate through the connecting rod 601. When the duvet cover is rotated 180 degrees, the handle 613 is released. The spring force generated by the release of the spring 611 pushes the pin 609 into the corresponding insertion hole 614 through the elliptical plate 612 to complete the positioning and fixation. During the quilting process, the moving frame 2 drives the quilting assembly 4 to move along the moving rod 3 to process the duvet cover. When it is necessary to turn it over, the above operation is performed to rotate the duvet cover 180 degrees to process the other side of the duvet cover. The entire working process is reliably clamped by the rotating rod head 603 driving the pressure plate 605, the duvet cover is positioned at multiple angles by the rotation of the turntable 607, the quick locking is achieved by the engagement of the pin 609 and the insertion hole 614, the spring 611 mechanism ensures automatic reset, the rubber strip 606 provides anti-slip protection, and the handle 613 design makes operation more convenient, thereby achieving efficient quilting processing of the duvet cover.

[0036] When cleaning the surface of the duvet cover is required, the operator applies force to the knob 707 by rotating it using the arc groove 708 on the arc surface. The arc groove 708 provides a non-slip grip to prevent slippage during rotation. The knob 707 drives the lead screw 706 to rotate inside the concave plate 705. Since the two ends of the lead screw 706 have threads in opposite directions, the rotation of the lead screw 706 synchronously drives the two rectangular plates 709 to move towards or away from each other along the inner side of the concave plate 705. The rectangular plates 709 drive the cleaning brushes 710 to adjust their spacing to suit the thickness of the duvet cover. After the two cleaning brushes 710 contact the upper and lower surfaces of the duvet cover, they push the connecting plate 704 to apply thrust. The connecting plate 704 slides horizontally along the axis of the slide rod 702 through the connecting cylinder 703. The connecting cylinder 703 drives the concave plate 705 to move, and the concave plate 705 pulls the cleaning brushes 710 through the rectangular plates 709 to clean the surface of the duvet cover and remove lint and impurities. After cleaning, move the cleaning brush 710 to the slot 711 and rotate the connecting cylinder 703 90 degrees around the axis of the sliding rod 702, turning the cleaning brush 710 into a vertical position. When the connecting plate 704 is in contact with the inner wall of the slot 711, the magnetic piece 712 attracts the iron connecting plate 704 for fixed storage. When it is needed for reuse, rotate the connecting cylinder 703 in the opposite direction to separate the connecting plate 704 from the magnetic piece 712, and restore the cleaning brush 710 to a horizontal working state. The entire cleaning process is achieved by adjusting the spacing of the cleaning brushes 710 by rotating the knob 707, moving the cleaning brush 710 for cleaning by pushing the connecting plate 704, changing the working state by rotating the connecting cylinder 703, and fixing it in place by the magnetic piece 712. The arc groove 708 ensures anti-slip operation. The cleaning brush 710 continuously contacts the surface of the casing during movement to complete the cleaning operation, and the magnetic fixation method ensures the stability of the stored state.
