[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] In this invention, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0041] like Figure 1 As shown, a mattress trim handle production line according to one embodiment of the present invention includes a trim side and vertical handle overlocking machine 1, a horizontal handle overlocking machine 2, a fully automatic labeling machine 3, and an automatic sewing machine 4. One end of the trim side and vertical handle overlocking machine 1 is used for feeding, the other end of the trim side and vertical handle overlocking machine 1 is connected to one end of the horizontal handle overlocking machine 2, the other end of the horizontal handle overlocking machine 2 is connected to one end of the fully automatic labeling machine 3, the other end of the fully automatic labeling machine 3 is connected to one end of the automatic sewing machine 4, and the other end of the automatic sewing machine 4 is used for discharging.

[0042] In the above scheme, the side and vertical handle overlock machines can continuously sew the handle straps to one side of the mattress, and the horizontal handle overlock machine 2 can continuously sew the handle straps to the other side of the mattress; the fully automatic label machine 3 transports the label to the fabric, so that the label and the fabric can be sewn together; the automatic sewing machine 4 is used to realize the double-sided sewing of the fabric. After the double-sided sewing is completed, the processing is finished. The whole process does not require manual operation, has a high degree of automation, can improve production efficiency, and reduce enterprise production costs.

[0043] like Figure 2As shown, in one embodiment, the overlock machine 1 for both sides of the welt and the vertical handle includes a first frame 5, a first worktable 6, a first conveyor plate 7, and a first sewing machine head 8. The first worktable 6 is fixedly installed on the first frame 5, the first conveyor plate 7 is fixedly installed on the first frame 5 and located above the first worktable 6, and the first sewing machine head 8 is installed on the first worktable 6. The overlock machine 1 for both sides of the welt and the vertical handle also includes a first conveying mechanism 9, a pre-storage mechanism 10, a first pressing mechanism 11, and a first gripping mechanism 12. The first conveying mechanism 9, the pre-storage mechanism 10, the first pressing mechanism 11, and the first gripping and feeding mechanism 12 are all fixedly installed on the first workbench 6. The first conveying mechanism 9 is located at the output end of the first conveying plate 7 and is used to convey the fabric from the input end of the first conveying plate 7 to the output end of the first conveying plate 7. The first gripping and feeding mechanism 12 is used to grip and feed the handle fabric to the pre-storage mechanism 10. The first pressing mechanism 11 is used to press the handle fabric stored in the pre-storage mechanism 10 onto the fabric located on the first conveying plate 7. The first sewing machine head 8 is used to sew the handle fabric onto the fabric.

[0044] In the aforementioned mattress handle overlock machine 1, the first conveying mechanism 9 transports the fabric from the input end of the first conveyor plate 7 to the output end, while the gripping mechanism places the handle strap on the pre-storage mechanism 10 to facilitate the first pressing mechanism 11 directly pressing the handle strap onto the fabric. Once the handle strap is pressed onto the fabric (i.e., the mattress side) by the first pressing mechanism 11, it can be sewn onto the fabric by the first sewing machine head 8. The first conveying mechanism 9, the pre-storage mechanism 10, the first pressing mechanism 11, and the first gripping mechanism 12, working in conjunction with the first sewing machine head 8, can continuously sew the handle strap onto the mattress side. The entire process requires no manual operation. Compared to existing mattress handle overlock machines, it has a higher degree of automation, improving production efficiency and reducing enterprise production costs.

[0045] like Figure 3As shown, in one embodiment, the first conveying mechanism 9 includes a first servo motor 21, a first driving roller 22, a first driven roller 23, a first support plate 24, and a first telescopic cylinder 25. There are two first support plates 24, which are parallel to each other and fixedly mounted on the first worktable 6. The first driving roller 22 is rotatably mounted between the two first support plates 24. The first servo motor 21 is fixedly mounted on one of the first support plates 24, and the output shaft of the first servo motor 21 is connected to one end of the first driving roller 22. The first driven roller 23 is installed between two first support plates 24 and above the first driving roller 22. The two ends of the first driven roller 23 are slidably connected to the two first support plates 24 respectively. There are two first telescopic cylinders 25, which are fixedly installed on the two first support plates 24 respectively. The piston rods of the two first telescopic cylinders 25 are fixedly connected to the two ends of the first driven roller 23 respectively. A first gap is left between the first driving roller 22 and the first driven roller 23. The first gap is adjacent to the output end of the first conveying plate 7.

[0046] The first gap is used to allow fabric located on the first conveyor plate 7 to pass through. By controlling the extension and retraction of the first telescopic cylinder 25, the first driven roller 23 can be moved up and down along the height direction of the first support plate 24, thereby controlling the size of the first gap between the first driven roller 23 and the first driving roller 22, so as to transport fabric of different thicknesses from the input end of the first conveyor plate 7 to the output end of the first conveyor plate 7 by driving the first driving roller 22 to rotate.

[0047] In one embodiment, the first conveying mechanism 9 further includes a first gear 26, and both first support plates 24 are provided with first slide rails 27. The two ends of the first driven roller 23 are slidably connected to the first slide rails 27. The first gear 26 is fixedly installed at one end of the first driving roller 22 and one end of the first driven roller 23, respectively. When the first gear 26 on the first driving roller 22 meshes with the first gear 26 on the first driven roller 23, the first driving roller 22 and the first driven roller 23 can rotate synchronously by driving the first servo motor 21 to better convey the fabric.

[0048] like Figures 4-5As shown, in one embodiment, the first gripping and conveying mechanism 12 includes a second support plate 42, a second telescopic cylinder 43, a first slide rail 44, a first slide plate 45, a third telescopic cylinder 46, a handle cloth storage frame 47, a first connecting plate 48, and a cylinder suction cup 49. The second support plate 42 is fixedly installed on the first workbench 6. The second telescopic cylinder 43 and the first slide rail 44 are both fixedly installed on the second support plate 42. The piston rod of the second telescopic cylinder 43 is fixedly connected to the first slide plate 45. The first slide plate 45 is slidably connected to the first slide rail 44. The third telescopic cylinder 46 is fixedly installed on the first slide plate 45. The cylinder suction cup 49 is fixedly installed on the piston rod of the third telescopic cylinder 46 through the first connecting plate 48. The first slide rail 44 is parallel to the axis of the second telescopic cylinder 43. The first slide rail 44 is located above the first conveying plate 7 and spans the first conveying plate 7. The handle cloth storage frame 47 is fixedly installed on the first workbench 6 and located below the first slide rail 44.

[0049] The mattress handle cloth is stored in the handle cloth storage box 47. By controlling the third telescopic cylinder 46 and the cylinder suction cup 49, the mattress handle cloth can be picked up. Then, by controlling the second telescopic cylinder 43 and the third telescopic cylinder 46, the mattress handle cloth can be placed on the pre-storage mechanism 10 so that the first pressing mechanism 11 can press the mattress handle cloth onto the fabric.

[0050] like Figures 4-7 As shown, in one embodiment, the first gripping and conveying mechanism 12 further includes a second servo motor 50, a third support plate 51, a second lead screw 52, ​​a second slide plate 53, and a first push plate 54. The third support plate 51 is fixedly installed on the first worktable 6 and located below the first worktable 6. The second servo motor 50 is fixedly installed on the end of the third support plate 51 away from the first worktable 6. The second slide plate 53 passes through the first worktable 6 and the handle cloth storage frame 47 and is slidably connected to both the first worktable 6 and the handle cloth storage frame 47. The output shaft of the second servo motor 50 is fixedly connected to the second lead screw 52. The second lead screw 52 is threadedly connected to one end of the second slide plate 53. The other end of the second slide plate 53 is fixedly connected to the push plate. The push plate and the other end of the second slide plate 53 are both located inside the handle cloth storage frame 47.

[0051] The second lead screw 52 is threadedly connected to the second slide plate 53. When the second servo motor 50 rotates, the second slide plate 53 slides up and down relative to the handle cloth storage frame 47, thereby driving the first push plate 54 to move up and down. By controlling the action of the second servo motor 50, the first push plate 54 can be driven to move upward, so that the mattress handle cloth in the handle cloth storage frame 47 moves upward and closer to the opening of the handle cloth storage frame 47, so that the cylinder suction cup 49 can pick it up and transport it to the pre-storage mechanism 10.

[0052] like Figure 8As shown, in one embodiment, the pre-storage mechanism 10 includes a support plate 28, a first support frame 29, a first rotating shaft 30, and a fourth telescopic cylinder 31. The first support frame 29 is inverted U-shaped and fixedly installed on the first worktable 6. The first conveying plate 7 passes through the first support frame 29. The first rotating shaft 30 is located in the first support frame 29 and is rotatably connected to the first support frame 29. One end of the support plate 28 is fixedly connected to the first rotating shaft 30. The fourth telescopic cylinder 31 is fixedly installed on the first support frame 29. The piston rod of the fourth telescopic cylinder 31 is fixedly connected to the other end of the support plate 28. The first rotating shaft 30 and the support plate 28 are both located above the first conveying plate 7.

[0053] Since the other end of the support plate 28 is fixedly connected to the piston rod of the fourth telescopic cylinder 31, and one end of the support plate 28 is fixedly connected to the first rotating shaft 30, when the first pressing mechanism 11 moves downwards towards the other end of the support plate 28, the support plate 28 will rotate around the first rotating shaft 30 as the rotation axis towards the first worktable 6, thereby pressing the mattress handle cloth placed on the other end of the support plate 28 onto the fabric. The pre-storage mechanism 10 works in conjunction with the first pressing mechanism 11 to quickly and accurately press the mattress handle cloth onto the fabric, making it convenient for the first sewing machine head 8 to sew the mattress handle cloth onto the fabric.

[0054] like Figures 12-13 As shown, in one embodiment, the first pressing mechanism 11 includes a third servo motor 32, a second support frame 33, a rack 34, a second gear 35, a second slide rail 36, a third sliding plate 37, a fifth telescopic cylinder 38, a second connecting plate 39, a first connecting rod 40, and a first pressing block 41. The second support frame 33 is fixedly installed on the first workbench 6 and located on one side of the first conveying plate 7. The rack 34 and the second slide rail 36 are both fixedly installed on the third sliding plate 37 and are parallel to the moving direction of the first conveying plate 7. The third sliding plate 37 is slidably connected to the slide rail. The third servo motor 32 is fixedly installed on the slide rail 37. The output shaft of the third servo motor 32 is fixedly connected to the second gear 35, which meshes with the rack 34. The fifth telescopic cylinder 38 is fixedly installed on the third slide plate 37. The second connecting plate 39 is fixedly connected to the piston rod of the fifth telescopic cylinder 38 and is located above the first conveying plate 7. One end of the first connecting rod 40 is fixedly connected to the second connecting plate 39, and the other end of the second connecting rod is fixedly connected to the first pressure block 41. The first connecting rod 40 is perpendicular to the first conveying plate 7, and both the first connecting rod 40 and the first pressure block 41 are located above the first conveying plate 7.

[0055] By controlling the rotation of the third servo motor 32, the second gear 35 can be driven to rotate, thereby driving the third slide plate 37 to slide along the second slide rail 36. Since the third slide plate 37 and the second slide rail 36 are both parallel to the movement direction of the first conveyor plate 7, the positions of the third slide plate 37 and the fifth telescopic cylinder 38 can be adjusted through the third servo motor 32, the third slide plate 37, the gear, the rack 34, and the second slide rail 36. When the fifth telescopic cylinder 38 is activated and presses the mattress handle cloth onto the fabric through the first connecting rod 40 and the first pressure block 41, by controlling the second servo motor 50 to rotate synchronously with the first servo motor 21, the mattress handle cloth can be moved to the position of the first sewing machine head 8, so that the first sewing machine head 8 can sew the mattress handle cloth onto the fabric.

[0056] like Figures 14-15 As shown, in one embodiment, the overlock machine 1 for both sides of the welt and the vertical handle also includes a first adjustment mechanism 17 and a second adjustment mechanism 18. The first sewing machine head 8 includes a first head 19 and a second head 20. The first adjustment mechanism 17 and the second adjustment mechanism 18 are fixedly installed on the first workbench 6. The first head 19 is fixedly installed on the first adjustment mechanism 17, and the second head 20 is fixedly installed on the second adjustment mechanism 18. The first adjustment head and the second adjustment head are located on both sides of the first conveyor plate 7. The first adjustment mechanism 17 is used to adjust the position of the first head 19, and the second adjustment head is used to adjust the position of the second head 20.

[0057] The positions of the first machine head 19 and the second machine head 20 relative to the first conveyor plate 7 can be adjusted by the first adjustment mechanism 17 and the second adjustment mechanism 18, which facilitates the sewing of mattress handle fabrics of different sizes and improves the applicability of the overlock machine.

[0058] In one embodiment, the overlock machine 1 for both sides of the strip and the vertical handle also includes a guide mechanism 14, which is fixedly installed on the first frame 5 and adjacent to the input end of the first conveyor plate 7. The guide mechanism 14 is used to guide the fabric to the input end of the first conveyor plate 7.

[0059] In one embodiment, the side rails and vertical handle overlock machine 1 also include a feeding mechanism 15 located on the side of the guide mechanism 14 away from the first conveyor plate 7, the feeding mechanism 15 being used to store the fabric roll.

[0060] like Figures 7-9As shown, in one embodiment, the overlocking machine 1 for both sides of the strip and the vertical handle also includes a first feeding mechanism 13. The first feeding mechanism 13 includes a third support frame 55, a fourth support plate 56, a fourth servo motor 57, a second driving roller 58, a second driven roller 59, a sixth telescopic cylinder 60, a cutter 61, a second rotating shaft 62, a pad 63, and a slide base 64. The third support frame 55 is fixedly installed on the first workbench 6. The first driving roller 22 and the second driven roller 59 are both fixedly installed on the third support frame 55 and are rotatably connected to the third support frame 55. The fourth servo motor 57 is fixedly installed on the third support frame 55. The output shaft of the fourth servo motor 57 passes through... The belt is connected to one end of the second driving roller 58. A second gap is left between the second driving roller 58 and the second driven roller 59 to allow the handle cloth to pass through. The slide base 64 is provided with a second slide 65. The outlet end of the second slide 65 is adjacent to the second gap. The pad 63 is fixedly installed on one end of the third support frame 55 near the first conveyor plate 7. The fourth support plate 56 is fixedly installed on the top of the third support frame 55. The sixth telescopic cylinder 60 is fixedly installed on the fourth support plate 56. The piston rod of the sixth telescopic cylinder 60 is hinged to one end of the cutter 61. The other end of the cutter 61 is rotatably connected to the third support frame 55 through the second rotating shaft 62. The cutter 61 is located above the pad 63.

[0061] One end of the mattress handle fabric passes sequentially through the second slide rail 65 and the second gap. When the fourth servo motor 57 rotates, the mattress handle fabric moves towards the support plate 28. When a portion of the mattress handle fabric moves onto the support plate 28, the sixth telescopic cylinder 60 is driven to move the cutter 61 towards the pad 63, cutting the mattress handle fabric located between the cutter 61 and the pad 63. By setting the first feeding mechanism 13, the mattress handle fabric can be easily conveyed onto the support plate 28 so that the first pressing mechanism 11 can press the mattress handle fabric onto the fabric.

[0062] The first feeding mechanism 13 works in conjunction with the first gripping and feeding mechanism 12 to cyclically feed mattress handle fabric to the pre-storage mechanism 10, which can improve the working performance of the overlock machine, enabling the overlock machine to work continuously and efficiently, and further improving the automation level of the overlock machine.

[0063] In one embodiment, such as Figure 2 , Figure 13 As shown, transparent doors and windows 16 are installed around the first workbench 6 to facilitate operators to check the working status of the overlock machine and improve the safety protection performance of the overlock machine.

[0064] like Figure 16As shown, in one embodiment, the horizontal handle overlock machine 2 includes a second frame 66, a second worktable 67, a second conveyor plate 68, and a second sewing machine head 69. The second worktable 67 is fixedly mounted on the second frame 66, and the second sewing machine head 69 and the second conveyor plate 68 are both fixedly mounted on the second worktable 67. The horizontal handle overlock machine 2 also includes a second conveying mechanism 70, a second gripping mechanism 71, a second feeding mechanism 72, and a second pressing mechanism 73. All are fixedly installed on the second workbench 67. The second conveying mechanism 70 is located at the output end of the second conveying plate 68 and is used to convey the fabric from the input end of the second conveying plate 68 to the output end of the second conveying plate 68. The second feeding mechanism 72 is used to convey the handle belt. The second gripping and feeding mechanism 71 is used to grip and feed the handle belt located on the second feeding mechanism 72 to the area directly below the second sewing machine head 69. The second pressing mechanism 73 is used to press the handle belt located on the second gripping and feeding mechanism 71 onto the fabric located on the second conveying plate 68. The second sewing machine head 69 is used to sew the handle belt onto the fabric.

[0065] In the aforementioned horizontal handle overlock machine 2, the second conveying mechanism 70 is used to convey the fabric from the input end to the output end of the second conveyor plate 68, the second feeding mechanism 72 is used to convey the handle strap, and the second gripping mechanism 71 is used to grip and feed the handle strap located on the second feeding mechanism 72 to directly below the second sewing machine head 69 so that the pressing mechanism can directly press the handle strap onto the fabric. After the handle strap is pressed onto the fabric (i.e., the side of the mattress) by the second pressing mechanism 73, the handle strap can be sewn onto the fabric by the second sewing machine head 69. The second conveying mechanism 70, the second gripping mechanism 71, the second feeding mechanism 72, and the second pressing mechanism 73, together with the second sewing machine head 69, can continuously sew the handle strap onto the side of the mattress. The entire process requires no manual operation. Compared with existing mattress handle overlock machines, it has a higher degree of automation, which can improve production efficiency and reduce enterprise production costs.

[0066] like Figures 17-18 As shown, in one embodiment, the fully automatic label machine 3 includes a third frame 74 and a third worktable 75. The third worktable 75 is used to place fabric and is mounted on the third frame 74. The third frame 74 is provided with a fixed platform 76, a suction device 77, a first feeding device 78, and a first sewing device 79 in sequence along the label conveying direction. The fixed platform 76 is used to store labels. The suction device 77 is used to transfer the labels located on the fixed platform 76 to the first feeding device 78. The first feeding device 78 is used to place the labels onto the fabric. The first sewing device 79 is used to sew the labels onto the fabric. The fixed platform 76, the suction device 77, the first feeding device 78, and the first sewing device 79 are all located above the third worktable 75.

[0067] The fully automatic label machine 3 solves the problems of low efficiency and poor quality in traditional label sewing by incorporating a third frame 74 for support, a third worktable 75 for holding fabric, a fixed platform 76 for storing labels, a suction device 77 for transporting labels to a first feeding device 78, a first feeding device 78 for transporting labels onto fabric, and a first sewing device 79 for sewing labels onto fabric.

[0068] like Figures 19-20 As shown, in one embodiment, the automatic sewing machine 4 includes a fourth worktable 80, a cutting device 81, a second sewing device 82, and a second feeding device 83. The fourth worktable 80 is provided with a cutting position, a feeding position, and a sewing position in sequence along the fabric feeding direction. The cutting device 81 is used to cut the fabric and is located at the cutting position. The second sewing device 82 is used to sew the fabric and is located at the sewing position. The second feeding device 83 includes a fourth frame 84 and a clamping mechanism 85 and a flipping mechanism 86 disposed on the fourth frame 84. The fourth frame 84 is mounted on the fourth worktable 80. The clamping mechanism 85 can reciprocate relative to the fourth frame 84 between the cutting position and the feeding position. The flipping mechanism 86 is located in the feeding position and is used to clamp the fabric and flip it.

[0069] The aforementioned automatic sewing machine 4 improves its automation level by setting a cutting device 81, a second sewing device 82, and a second feeding device 83 on the fourth worktable 80. This solves the problem that traditional sewing equipment requires high skill from workers and involves high labor intensity, making it impossible to achieve large-scale automated production. By setting a clamping mechanism 85, the machine clamps the fabric and moves it between the cutting and feeding positions, thus solving the fabric conveying problem. By setting a flipping mechanism 86, the machine flips the fabric, enabling double-sided sewing, and completing the processing after double-sided sewing.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
