The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0037] like Figure 1 As shown, a vertical handle overlock machine for both sides of a sash in one embodiment of the present invention comprises a frame 1, a workbench 2, a conveying plate 3, a sewing machine head 4, a conveying mechanism 5, a pre-storage mechanism 6, a pressing mechanism 7, and a grabbing mechanism 8. The workbench 2 is fixedly mounted on the frame 1, and the conveying plate 3 is fixedly mounted on the frame 1 and located above the workbench 2. The sewing machine head 4 is mounted on the workbench 2, and the conveying mechanism 5, the pre-storage mechanism 6, the pressing mechanism 7, and the grabbing mechanism 8 are all fixedly mounted on the workbench 2. The conveying mechanism 5 is located at the output end of the conveying plate 3 and is used to convey the fabric from the input end of the conveying plate 3 to the output end of the conveying plate 3. The grabbing mechanism 8 is used to grab the handle tape to the pre-storage mechanism 6. The pressing mechanism 7 is used to press the handle tape stored on the pre-storage mechanism 6 onto the fabric on the conveying plate 3. The sewing machine head 4 is used to sew the handle tape onto the fabric.

[0038] In the aforementioned vertical handle overlock machine for both sides of the mattress, the conveying mechanism 5 is used to transport the fabric from the input end to the output end of the conveyor plate 3, while the gripping mechanism is used to place the handle strap on the pre-storage mechanism 6 to facilitate the pressing mechanism 7 to directly press the handle strap onto the fabric. Once the handle strap is pressed onto the fabric (i.e., the side of the mattress) by the pressing mechanism 7, the sewing machine head 4 can sew the handle strap to the fabric. The conveying mechanism 5, pre-storage mechanism 6, pressing mechanism 7, and gripping mechanism 8, in conjunction with the sewing machine head 4, can continuously sew the handle strap to the side of the mattress. The entire process requires no human intervention. Compared to existing mattress handle strap overlock machines, this machine has a higher degree of automation, which can improve production efficiency and reduce production costs.

[0039] In one embodiment, Figure 2As shown, the conveying mechanism 5 includes a first servo motor 50, a first active roller 51, a first driven roller 52, a first support plate 53 and a first telescopic cylinder 54. There are two first support plates 53, which are parallel to each other and fixedly mounted on the workbench 2. The first active roller 51 is rotatably mounted between the two first support plates 53. The first servo motor 50 is fixedly mounted on one of the first support plates 53. The output shaft of the first servo motor 50 is transmission-connected to one end of the first active roller 51. The first driven roller 52 is mounted between the two first support plates 53 and is located above the first active roller 51. The two ends of the first driven roller 52 are respectively slidably connected to the two first support plates 53. There are two first telescopic cylinders 54, which are respectively fixedly mounted on the two first support plates 53. The piston rods of the two first telescopic cylinders 54 are respectively fixedly connected to the two ends of the first driven roller 52. A first gap is left between the first active roller 51 and the first driven roller 52, and the first gap is adjacent to the output end of the conveying plate 3.

[0040] The first gap is used to allow fabric on the conveyor plate 3 to pass through. By controlling the extension and contraction of the first telescopic cylinder 54, the first driven roller 52 can be moved up and down along the height direction of the first support plate 53, thereby controlling the size of the first gap between the first driven roller 52 and the first active roller 51. By driving the first active roller 51 to rotate, fabrics of different thicknesses can be conveyed from the input end of the conveyor plate 3 to the output end of the conveyor plate 3.

[0041] In one embodiment, Figure 2 As shown, the conveying mechanism 5 further includes a first gear 55. A first slideway 56 is provided on each of the two first support plates 53. Both ends of the first driven roller 52 are slidably connected to the first slideways 56. The first gear 55 is fixedly mounted on one end of the first active roller 51 and one end of the first driven roller 52. When the first gear 55 on the first active roller 51 meshes with the first gear on the first driven roller 52, the first servo motor is driven to cause the first active roller 51 and the first driven roller 52 to rotate synchronously, thereby better conveying the fabric.

[0042] In one embodiment, Figure 3 as well as Figure 4As shown, the grabbing mechanism 8 includes a second support plate 80, a second telescopic cylinder 81, a first slide rail 82, a first slide plate 83, a third telescopic cylinder 84, a handle belt storage frame 85, a first connecting plate 86 and a cylinder suction cup 87. The second support plate 80 is fixedly mounted on the workbench 2, the second telescopic cylinder 81 and the first slide rail 82 are both fixedly mounted on the second support plate 80, the piston rod of the second telescopic cylinder 81 is fixedly connected to the first slide plate 83, the first slide plate 83 is slidingly connected to the first slide rail 82, the third telescopic cylinder 84 is fixedly mounted on the first slide plate 83, and the cylinder suction cup 87 is fixedly mounted on the piston rod of the third telescopic cylinder 84 through the first connecting plate 86. The first slide rail 82 is parallel to the axis of the second telescopic cylinder 81, the first slide rail 82 is located above the conveying plate 3 and spans the conveying plate 3, and the handle belt storage frame 85 is fixedly mounted on the workbench 2 and is located below the first slide rail 82.

[0043] The mattress handle strap is stored in the handle strap storage frame 85. By controlling the movement of the third telescopic cylinder 84 and the cylinder suction cup 87, the mattress handle strap can be sucked up. Then, by controlling the movement of the second telescopic cylinder 81 and the third telescopic cylinder 84, the mattress handle strap can be placed on the pre-storage mechanism 6 so that the pressing mechanism 7 can press the mattress handle strap onto the fabric.

[0044] In one embodiment, Figure 3 、 Figure 4 、 Figure 5 as well as Figure 6 As shown, the grabbing mechanism 8 also includes a second servo motor 88, a third support plate 89, a second screw rod 810, a second slide plate 811 and a first push plate 812. The third support plate 89 is fixedly mounted on the workbench 2 and is located below the workbench 2. The second servo motor 88 is fixedly mounted on the end of the third support plate 89 away from the workbench 2. The second slide plate 811 passes through the workbench 2 and the handle strap storage frame 85. The second slide plate 811 is slidingly connected to the workbench 2 and the handle strap storage frame 85 respectively. The output shaft of the second servo motor 88 is fixedly connected to the second screw rod 810. The second screw rod 810 is threadedly connected to one end of the second slide plate 811. The other end of the second slide plate 811 is fixedly connected to the first push plate 812. The other ends of the first push plate 812 and the second slide plate 811 are both located in the handle strap storage frame 85.

[0045] The second screw rod 810 is threadedly connected to the second slide plate 811. When the second servo motor 88 rotates, the second slide plate 811 slides up and down relative to the handle strap storage frame 85, thereby driving the first push plate 812 to move up and down. By controlling the operation of the second servo motor 88, the first push plate 812 can be driven upward, causing the mattress handle strap located in the handle strap storage frame 85 to move upward as a whole and approach the opening of the handle strap storage frame 85, thereby facilitating the cylinder suction cup 87 to suck the mattress handle strap into the pre-storage mechanism 6.

[0046] In one embodiment, Figure 7 As shown, the pre-storage mechanism 6 includes a carrying plate 60, a first support frame 61, a first rotating shaft 62 and a fourth telescopic cylinder 63. The first support frame 61 is inverted U-shaped and is fixedly installed on the workbench 2. The conveying plate 3 passes through the first support frame 61. The first rotating shaft 62 is located in the first support frame 61 and is rotatably connected to the first support frame 61. One end of the carrying plate 60 is fixedly connected to the first rotating shaft 62. The fourth telescopic cylinder 63 is fixedly installed on the first support frame 61. The piston rod of the fourth telescopic cylinder 63 is fixedly connected to the other end of the carrying plate 60. The first rotating shaft 62 and the carrying plate 60 are both located above the conveying plate 3.

[0047] Because the other end of the carrier plate 60 is fixedly connected to the piston rod of the fourth telescopic cylinder 63, and one end of the carrier plate 60 is fixedly connected to the first rotating shaft 62, when the pressing mechanism 7 moves downwardly relative to the other end of the carrier plate 60, the carrier plate 60 rotates about the first rotating shaft 62 toward the workbench 2, thereby pressing the mattress handle strap placed on the other end of the carrier plate 60 against the fabric. The pre-storage mechanism 6 cooperates with the pressing mechanism 7 to quickly and accurately press the mattress handle strap against the fabric, facilitating the sewing machine head 4 to sew the mattress handle strap onto the fabric.

[0048] In one embodiment, Figure 11 as well as Figure 12As shown, the clamping mechanism 7 includes a third servo motor 70, a second support frame 71, a rack 72, a second gear 73, a second slide rail 74, a third slide plate 75, a fifth telescopic cylinder 76, a second connecting plate 77, a first connecting rod 78 and a first pressing block 79. The second support frame 71 is fixedly mounted on the workbench 2 and is located on one side of the conveying plate 3. The rack 72 and the second slide rail 74 are both fixedly mounted on the third slide plate 75 and are parallel to the moving direction of the conveying plate 3. The third slide plate 75 is slidably connected to the slide rail. The third servo motor 70 is fixedly mounted on the third slide plate 75 The output shaft of the third servo motor 70 is fixedly connected to the second gear 73, the gear is engaged with the rack 72, the fifth telescopic cylinder 76 is fixedly mounted on the third slide 75, the second connecting plate 77 is fixedly connected to the piston rod of the fifth telescopic cylinder 76 and is located above the conveying plate 3, one end of the first connecting rod 78 is fixedly connected to the second connecting plate 77, the other end of the first connecting rod 78 is fixedly connected to the first pressure block 79, the first connecting rod 78 is perpendicular to the conveying plate 3, and the first connecting rod 78 and the first pressure block 79 are both located above the conveying plate 3.

[0049] By controlling the rotation of the third servo motor 70, the second gear 73 can be driven to rotate, thereby driving the third slide 75 to slide along the second slide rail 74. Since the third slide 75 and the second slide rail 74 are parallel to the movement direction of the conveyor plate 3, the position of the third slide 75 and the fifth telescopic cylinder 76 can be adjusted by the third servo motor 70, the third slide 75, the gear, the rack 72, and the second slide rail 74. When the fifth telescopic cylinder 76 is activated and presses the mattress handle strap against the fabric via the first connecting rod 78 and the first pressure block 79, the mattress handle strap can be moved to the position of the sewing machine head 4 by controlling the operation of the second servo motor 88 and rotating it synchronously with the first servo motor 50, thereby facilitating the sewing of the mattress handle strap to the fabric.

[0050] In one embodiment, Figure 13 as well as Figure 14As shown, the vertical handle overlock machine on both sides of the strip also includes a first adjusting mechanism 40 and a second adjusting mechanism 41, and the sewing machine head 4 includes a first head 42 and a second head 43. The first adjusting mechanism 40 and the second adjusting mechanism 41 are fixedly mounted on the workbench 2, the first head 42 is fixedly mounted on the first adjusting mechanism 40, and the second head 43 is fixedly mounted on the second adjusting mechanism 41. The first adjusting mechanism 40 and the second adjusting mechanism 41 are respectively located on both sides of the conveying plate 3, the first adjusting mechanism 40 is used to adjust the position of the first head 42, and the second adjusting mechanism 41 is used to adjust the position of the second head 43.

[0051] Through the first adjustment mechanism 40 and the second adjustment mechanism 41, the positions of the first head 42 and the second head 43 relative to the conveying plate 3 can be adjusted, which facilitates the sewing of mattress handle straps of different sizes and improves the applicability of the overlock machine.

[0052] Since the first adjustment mechanism 40 and the second adjustment mechanism 41 are conventional technical means in this technical field, they are not described in detail here.

[0053] In one embodiment, Figure 14 As shown, the vertical handle overlock machine on both sides of the strip further includes a guiding mechanism 10, which is fixedly mounted on the frame 1 and adjacent to the input end of the conveyor plate 3, and is used to guide the fabric to the input end of the conveyor plate 3.

[0054] In one embodiment, Figure 14 As shown, the vertical handle edge-locking machine on both sides of the strip further includes a discharge mechanism 11 located on the side of the guide mechanism 10 away from the conveying plate 3, and the discharge mechanism 11 is located on the discharge mechanism 11 for storing fabric rolls.

[0055] In one embodiment, Figure 8 、 Figure 9 as well as Figure 10As shown, the vertical handle edge locking machine on both sides of the strip also includes a feeding mechanism 9, which includes a third support frame 90, a fourth support plate 91, a fourth servo motor 92, a second active roller 93, a second driven roller 94, a sixth telescopic cylinder 95, a cutter 96, a second rotating shaft 97, a pad 98 and a slide base 99. The third support frame 90 is fixedly mounted on the workbench 2, the first active roller 51 and the second driven roller 94 are both fixedly mounted on the third support frame 90 and are rotatably connected to the third support frame 90, the fourth servo motor 92 is fixedly mounted on the third support frame 90, and the output shaft of the fourth servo motor 92 is connected to one end of the second active roller 93 through a belt. Then, a second gap is left between the second active roller 93 and the second driven roller 94 for the handle belt to pass through, and a second slide 910 is provided in the slide base 99, and the outlet end of the second slide 910 is adjacent to the second gap, and the pad 98 is fixedly mounted on one end of the third support frame 90 close to the conveying plate 3, and the fourth support plate 91 is fixedly mounted on the top of the third support frame 90, and the sixth telescopic cylinder 95 is fixedly mounted on the fourth support plate 91, and the piston rod of the sixth telescopic cylinder 95 is hinged to one end of the cutter 96, and the other end of the cutter 96 is rotatably connected to the third support frame 90 through the second rotating shaft 97, and the cutter 96 is located above the pad 98.

[0056] One end of the mattress handle strap sequentially passes through the second slideway 910 and the second gap. When the fourth servo motor 92 rotates, the mattress handle strap moves toward the support plate 60. When a portion of the mattress handle strap moves onto the support plate 60, the sixth telescopic cylinder 95 is actuated to move the cutter 96 toward the backing plate 98, severing the mattress handle strap between the cutter 96 and the backing plate 98. The feed mechanism 9 facilitates the delivery of the mattress handle strap to the support plate 60, allowing the pressing mechanism 7 to press the mattress handle strap against the fabric.
