Description

Technical Field

[0001] This utility model relates to the field of quilting equipment technology, and in particular to a transverse side cord quilting mechanism and a four-sided quilting machine. Background Technology

[0002] In existing technologies, four-sided quilting machines require quilting the edge cords to ensure a smooth and crisp quilt surface. However, current quilting equipment struggles to position the edge cords during the quilting process, necessitating welding for positioning before quilting. This increases costs and reduces processing efficiency. Therefore, this paper proposes a mechanism that positions and quilts the edge cords during the quilting process to improve quilt processing efficiency. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a transverse edge cord quilting mechanism and a four-sided quilting machine, which can achieve synchronous positioning and quilting of the transverse edge cords, thereby improving quilting efficiency.

[0004] This utility model discloses a transverse edge cord quilting mechanism, including a frame and four slide rails disposed on the top of the frame. A quilting head is disposed on every two slide rails. A stand is disposed on the side of the frame on the fabric input side, and a guide rail is disposed on the stand. One end of the guide rail extends outward from the end of the frame. A slide plate is disposed on the guide rail within the frame area, and another slide plate is disposed on the guide rail outside the frame area. A guide pressure plate is disposed between the two slide plates, and the guide pressure plate has a channel for the edge cord to pass through. Two side-by-side edge cord guide sleeves are disposed on the slide plate within the frame area, and the edge cord guide sleeves are located at the end of the guide pressure plate. The two edge cord guide sleeves correspond to the positions of the quilting head. A reciprocating motion mechanism is disposed on the stand, and the reciprocating motion mechanism drives the slide plate to reciprocate on the guide rail. An edge cord cutting mechanism is disposed on the side of the quilting head near the guide slide plate.

[0005] The reciprocating motion mechanism has the following structure: synchronous pulleys are provided on the uprights at both ends of the guide rail, a drive motor is provided at one end of the uprights, the drive motor is connected to the synchronous pulleys, a synchronous belt is wound between the synchronous pulleys, and the end of the slide plate is fixedly connected to the synchronous belt.

[0006] The edge rope cutting mechanism includes a mounting frame fixed to the side of the quilting machine head. Two vertically downward telescopic cylinders are stacked on the mounting frame. The telescopic cylinder near the quilting machine head has two vertically downward needle-type suction cups at its telescopic end, each needle-type suction cup corresponding to one edge rope. The telescopic cylinder away from the quilting machine head has two pneumatic scissors obliquely arranged at its telescopic end, each pneumatic scissor corresponding to one edge rope.

[0007] A fixed guide roller and a movable guide roller are installed on the frame on the fabric input side. A vertically downward first cylinder is installed on the frame above the fixed guide roller. The end of the movable guide roller is provided with the extension end of the first cylinder. The slide passes between the fixed guide roller and the movable guide roller.

[0008] It also includes a feeding mechanism for inputting filler material and fabric. Two tensioning mechanisms are arranged vertically at intervals on the feeding mechanism near the upright. The tensioning mechanism is structured as follows: two guide rollers are arranged at intervals, and a tensioning roller is arranged between the guide rollers. Vertical guide grooves are provided on the feeding mechanism at both ends of the tensioning roller, and both ends of the tensioning roller are located in the guide grooves. Gears are provided at both ends of the tensioning roller, and vertical racks are provided on the feeding mechanism corresponding to the gears. The gears mesh with the racks.

[0009] In the tensioning mechanism above, a second cylinder is installed vertically downward on the feeding mechanism above the guide rollers on the side near the upright. The two ends of the guide rollers are located at the extension and retraction ends of the second cylinders.

[0031] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0032] Example 1:

[0033] like Figure 1-15As shown, this utility model discloses a transverse edge cord quilting mechanism, including a frame 4 and four slide rails 11 disposed on the top of the frame 4. A quilting head 12 is disposed on each pair of slide rails 11. A stand 5 is disposed on the side of the frame 4 on the fabric 20 input side, and a guide rail 6 is disposed on the stand 5. One end of the guide rail 6 extends outward from the end of the frame 4. A slide plate 7 is disposed on the guide rail 6 within the range of the frame 4, and a slide plate 7 is also disposed on the guide rail 6 outside the range of the frame 4. A guide plate 8 is provided between the two slide plates 7, and the guide plate 8 has a channel for the edge rope to pass through. Two side-by-side edge rope guide sleeves 29 are provided on the slide plate 7 within the frame 4. The edge rope guide sleeves 29 are located at the ends of the guide plate 8, and the two edge rope guide sleeves 29 correspond to the positions of the quilting head 12. A reciprocating motion mechanism is provided on the upright frame 5, and the reciprocating motion mechanism drives the slide plate 7 to reciprocate on the guide rail 6. An edge rope cutting mechanism is provided on the side of the quilting head 12 near the guide slide plate 7.

[0034] The frame 4 of the transverse edge cord quilting mechanism serves as the framework of the entire quilting machine, providing support and mounting for components; its specific structure is not limited. Two quilting heads 12 are mounted on four slide rails 11 at the top of the frame 4, one head for every two slide rails 11. The quilting heads 12 are existing, known structures that can move laterally on the slide rails 11 to sew the transverse edge cords to the fabric 20. They can also sew the fabric 20, filling material 21, and transverse edge cords together. A stand 5 is mounted on the side of the frame 4 on the fabric 20 input side. A guide rail 6 is mounted on the stand 5, and a slide plate 7 is mounted on the guide rail 6. A guide pressure plate 8 is mounted at the end of the slide plate 7. The guide pressure plate 8 is located between the two layers of fabric 20, hence the stand 5 needs to be positioned on the fabric 20 input side. The two layers of fabric 20 on the input side of fabric 20 are open. The slide plate 7 and guide plate 8 extend between the two layers of fabric 20 to the area where the edge cord needs to be sewn. The quilting head 12 is located above the two layers of fabric 20. The guide plate 8 extends from the outside of the frame 4 through the frame 4 into the inside of the frame 4. One end of the slide plate 7 of the guide plate 8 is within the frame 4, while the other end is outside the frame 4. A reciprocating motion mechanism drives the slide plate 7 and guide plate 8 to move back and forth, conveying the outer edge cord inward. The guide plate 8 has a channel inside for the edge cord to pass through. The outer edge cord passes through the channel to the edge cord guide sleeve 29 at the end, which is used to position the edge cord. The edge cord guide sleeve 29 is a known existing component.

[0035] During normal transverse edge cord sewing, the entire guide plate 8 is first moved into the machine frame 4 via a reciprocating motion mechanism, allowing the edge cord guide sleeve 29 at the end of the guide plate 8 to move across the width of the entire fabric 20. Simultaneously, the quilting head 12 moves to the corresponding position, at which point the transverse edge cord is located at one end of the width of the two layers of fabric 20. The quilting head 12 sews the fabric 20 and the edge cord together, sealing the end of the edge cord. During this process, the guide plate 8 retracts outward, and the quilting head 12 simultaneously sews the edge cord output from the guide plate 8 to ensure accurate positioning. The transverse sewing of the edge cord on the fabric 20 is completed when the guide plate 8 is completely removed from between the fabrics 20. At this point, the edge cord can be cut using the edge cord cutting mechanism, allowing for side edge sewing of the quilt.

[0036] The reciprocating motion mechanism is structured as follows: synchronous pulleys 9 are provided on the uprights 5 at both ends of the guide rail 6, a drive motor 27 is provided at one end of the uprights 5, the drive motor 27 is connected to the synchronous pulleys 9 for transmission, a synchronous belt 10 is wound between the synchronous pulleys 9, and the end of the slide plate 7 is fixedly connected to the synchronous belt 10.

[0037] The reciprocating motion mechanism uses a synchronous pulley 9 and a synchronous belt 10 in cooperation. The drive motor 27 controls the forward and reverse rotation of the synchronous pulley 9, thereby realizing the reciprocating motion of the slide plate 7 on the synchronous belt 10 on the track. The drive motor 27 can be a servo motor, which can precisely control the running direction and speed of the synchronous belt 10 to ensure the stable and controllable operation of the guide plate 8.

[0038] The edge rope cutting mechanism includes a mounting frame 22, which is fixed to the side of the quilting machine head 12. Two vertically downward telescopic cylinders 23 are stacked on the mounting frame 22. The telescopic end of the telescopic cylinder 23 near the quilting machine head 12 is provided with two vertically downward needle suction cups 24, each needle suction cup 24 corresponding to one edge rope. The telescopic end of the telescopic cylinder 23 away from the quilting machine head 12 is provided with two pneumatic scissors 25, each pneumatic scissors 25 corresponding to one edge rope.

[0039] When cutting the edge cord, the edge cord cutting mechanism needs to be located within the gap between the quilting machine head 12 and the guide pressure plate 8. To reduce the power required for the reciprocating motion of the edge cord cutting mechanism, it can be directly fixed to the mounting bracket 22 on the quilting machine head 12. This mounting bracket 22 is located on the side of the quilting machine head 12 closest to the guide pressure plate 8, i.e., between the quilting machine head 12 and the guide pressure plate 8. After the transverse edge cord is sewn, the guide pressure plate 8 detaches from the fabric 20, leaving a gap between them. The edge cord cutting mechanism is located above this gap. A vertically downward telescopic cylinder 23 is installed on the mounting bracket 22, with a needle suction cup 24 at its end. When edge cord cutting is required, the telescopic cylinder 23 moves downward, causing the needle suction cup 24 to adhere to the edge cord and pierce and suction it. Then, the telescopic cylinder 23 retracts, raising it to a certain height. Another telescopic cylinder 23 is also installed on its outer side, with a pneumatic scissors 25 corresponding to its telescopic end. After the side rope is raised, another telescopic cylinder 23 drives the pneumatic shears 25 to descend to the side rope and cut it. This design allows for rapid cutting of the side rope with high stability.

[0040] A fixed guide roller 13 and a movable guide roller 14 are provided on the frame 4 on the side of the fabric 20 input. A vertically downward first cylinder 28 is provided on the frame 4 above the fixed guide roller 13. The end of the movable guide roller 14 is provided with the telescopic end of the first cylinder 28. The slide plate 7 passes between the fixed guide roller 13 and the movable guide roller 14.

[0041] Two layers of fabric 20 enter the frame 4 from the fabric 20 input side and are sewn together by the quilting head 12. The lower layer of fabric 20 goes around the fixed guide roller 13 before entering the frame 4, while the upper layer of fabric 20 goes around the top and below the movable guide roller 14 before entering the frame 4. The movable guide roller 14 is located at the extension end of the first cylinder 28. The distance between the movable guide roller 14 and the fixed guide roller 13 can be controlled by extending and retracting the first cylinder 28 at both ends. Before the guide plate 8 and slide plate 7 enter the two layers of fabric 20, the movable guide roller 14 needs to move upward to increase the gap between the movable guide roller 14 and the fixed guide roller 13, thereby increasing the gap between the two layers of fabric 20 so that the guide plate 8 and slide plate 7 can enter through without interfering with the fabric 20. After the guide plate 8 is in place, the first cylinder 28 extends, causing the movable guide roller 14 to press down, thereby bringing the two layers of fabric 20 closer together for sewing.

[0042] It also includes a feeding mechanism 1 for inputting filler material 21 and fabric 20. Two tensioning mechanisms are arranged vertically at intervals on the feeding mechanism 1 near the upright frame 5. The tensioning mechanism is structured as follows: two guide rollers 15 are arranged at intervals, and a tensioning roller 16 is arranged between the guide rollers 15. Vertical guide grooves 17 are provided on the feeding mechanism 1 at both ends of the tensioning roller 16. Both ends of the tensioning roller 16 are located in the guide grooves 17. Gears 18 are provided at both ends of the tensioning roller 16. A vertical rack 19 is provided on the feeding mechanism 1 at the position corresponding to the gear 18. The gears 18 and rack 19 mesh.

[0043] The feeding mechanism 1 is used to convey the filler material 21 and fabric 20 into the frame 4 of the quilting mechanism, mainly for conveying the fabric 20. The fabric 20 needs to be kept taut during conveying, so two tensioning mechanisms are provided on the feeding mechanism 1. The upper tensioning mechanism tensions the upper layer of fabric 20, and the lower tensioning mechanism tensions the lower layer of fabric 20. The tensioning mechanism consists of two guide rollers 15 and one tensioning roller 16, with both ends of the tensioning roller 16 positioned within guide grooves 17. The fabric 20 passes over the guide rollers 15, and the tensioning roller 16 is positioned above the fabric 20. Under the influence of gravity, the tensioning roller 16 moves along the guide grooves 17, pulling the fabric 20 between the two guide rollers 15 downwards, thus achieving tension. Since the ends of the tensioning roller 16 can move freely within the guide grooves 17, measures are taken to prevent the tensioning roller 16 from tilting and causing the fabric 20 to be conveyed skewed. Gears 18 are rotatably mounted at both ends of the tension roller 16, and a vertical rack 19 is mounted on the feeding mechanism 1 corresponding to the gears 18, with the two meshing together. Under the action of gravity and the tension of the fabric 20, the tension roller 16 can rise and fall, but with the cooperation of the gears 18 and rack 19, both ends of the tension roller 16 remain horizontal and rise and fall synchronously, resulting in a better tension and stability effect on the fabric 20.

[0044] In the tensioning mechanism above, a second cylinder 26 is installed vertically downward on the feeding mechanism 1 above the two ends of the guide roller 15 near the upright frame 5. The two ends of the guide roller 15 are located at the extension and retraction ends of the second cylinder 26.

[0045] The upper tensioning mechanism tensions the upper layer of fabric 20. In actual use, since the upper layer of fabric 20 needs to wrap around the movable guide roller 14, the movable guide roller 14 needs to rise before the guide pressure plate 8 moves between the fabric 20. At this time, the upper layer of fabric 20 between the frame 4 and the tensioning mechanism will become loose and cannot be quickly tensioned. Therefore, the upper tensioning mechanism needs to be equipped with second cylinders 26 at both ends of the guide roller 15 near the upright 5. While the first cylinder 28 drives the movable guide roller 14 to rise, the second cylinder 26 retracts, driving the guide roller 15 to rise, thereby allowing the fabric 20 between the two to be quickly tensioned. This also rapidly increases the opening between the two layers of fabric 20, facilitating the entry of the guide pressure plate 8 and improving processing efficiency.
