Description

Technical Field

[0001] This utility model relates to the field of garment manufacturing technology, and in particular to an overlock sewing device. Background Technology

[0002] The seam allowance in clothing refers to the raised seam formed by overlocking the edges of fabric. In some garment manufacturing requirements, such as where seams intersect, the seams need to be turned to a specific side. For example, at the sleeve position, the end of the sleeve is first sewn to the front and back panels of the garment to form the first seam allowance. Then, the lower side of the sleeve is sewn together, and the front and back panels of the garment are sewn together to form the second seam allowance. At the armpit position, the first and second seams intersect. When sewing the second seam allowance, the upper and lower sections of the first seam allowance need to be turned to the same side, and its two ends are joined to the second seam allowance when overlocking it.

[0003] Currently, when sewing, the operator needs to manually press the seam bobby to a specific side and hold it down before pushing the garment to the overlock sewing machine's needle area for overlock sewing. This means the entire sewing operation must be done manually, which is inefficient. For safety reasons, the operator's hand cannot press the seam bobby too close to the overlock position, as this can cause the seam bobby to easily lift up to the other side during the movement. Utility Model Content

[0004] The main purpose of this invention is to propose an overlock sewing device that aims to solve the technical problems in the prior art where manual pushing of the garment and pressing down of the seam bob are required during overlock sewing, resulting in low safety and the seam bob easily lifting up.

[0005] To achieve the above objectives, this utility model proposes an overlock sewing device, comprising:

[0006] A frame, on which a processing platform is provided, and on which garment placement area and overlocking area are arranged opposite to each other;

[0007] An overlock sewing machine, which is fixed on the frame, and the overlock sewing machine is located on the overlock sewing area;

[0008] The first garment pressing assembly includes a left-right moving device, a first lifting moving device, a first garment pressing plate, and a pressing member. The left-right moving device is mounted on the frame, the first lifting moving device is mounted on the moving end of the left-right moving device, the first garment pressing plate is mounted on the moving end of the first lifting moving device, and the pressing member is fixed to the first garment pressing plate. The left-right moving device can drive the first lifting moving device, the first garment pressing plate, and the pressing member to move left and right between the garment placement area and the overlocking area. The first lifting moving device can drive the first garment pressing plate and the pressing member to move up and down. The first garment pressing plate can press the garment onto the processing platform, and the pressing member is used to press down the seam boning. The first garment pressing plate and the pressing member are offset from the overlocking machine, and in the front-back direction, the pressing member is located on the side of the first garment pressing plate closer to the overlocking machine.

[0009] The garment to be overlocked is placed on the garment placement area of ​​the processing platform. The already overlocked seam bob is positioned to the correct side. The first pressure plate moves to the top of the garment, with the pressure plate directly above the seam bob. Then, the first lifting and moving device drives the first pressure plate downwards, pressing the garment onto the processing platform. Once the overlocked edge is exposed outside the first pressure plate, the pressure plate holds down the seam bob to maintain its orientation. Next, the left and right moving device moves the first lifting and moving device, the first pressure plate, and the pressure plate toward the overlock machine located in the overlocking area. Under the pressure and friction of the first pressure plate, the garment moves toward the overlock machine. During this movement, the overlock machine overlocks the edge of the garment to be overlocked.

[0010] This overlock sewing equipment uses a first pressure plate to press down the garment and move it towards the overlock sewing machine for overlock sewing. Furthermore, it uses a pressure plate to press down the seam bob, which can be placed closer to the sewing position. This ensures that the seam bob remains on the desired side during the movement of the garment and the overlock sewing process, improving the safety of manual operation.

[0011] Preferably, a puncture needle is provided on the lower side of the bone-pressing component, and the puncture needle is used to puncture the bone.

[0012] When the pressure plate holds the suture bone in place, the puncture needle will penetrate into the suture bone. The puncture needle can further stabilize the position of the suture bone and further keep the orientation of the suture bone on the desired side.

[0013] Preferably, the processing platform is provided with a needle-reaming seam, which extends laterally between the garment placement area and the overlocking area, and the lower end of the puncture needle is located within the needle-reaming seam.

[0014] When the lower end of the puncture needle passes through the suture bone, the connection stability between the puncture needle and the suture bone can be improved. Therefore, a needle gap is set so that the lower end of the puncture needle can pass through the suture bone and clothing and enter the needle gap, so as to prevent the processing platform from pressing against the puncture needle.

[0015] Preferably, the overlock sewing equipment further includes a second garment pressing assembly, which is located above the garment placement area. The second garment pressing assembly includes a second lifting and moving device and a second pressing component. The second lifting and moving device is located on the frame, and the second pressing component is located on the moving end of the second lifting and moving device. The second lifting and moving device can drive the second pressing component to move up and down. In the front-back direction, the second pressing assembly is located on the side of the first pressing assembly closer to the overlock sewing machine. The second pressing component can press the garment onto the processing platform. The first pressing plate and the second pressing component are arranged in a front-back arrangement.

[0016] When placing the garment on the storage area, first lay the edge of the garment to be overlocked flat and arrange it under the second pressing component. The second lifting and moving device moves the second pressing component downwards to press and fix the edge of the garment to be overlocked. This leaves space under the first pressing plate for manual adjustment of the garment and seam boning. After adjustment, the first pressing plate presses the garment downwards, and the seam boning component presses down on the seam boning. Then, the second lifting and moving device moves the second pressing component upwards to leave the edge to be overlocked, and the first pressing plate then moves the garment towards the overlocking machine. By setting up the second pressing component, the position of the garment and seam boning can be assisted manually, making the garment positioning and overlocking position more accurate.

[0017] Preferably, the second pressing member is provided with a relief groove, the relief groove is provided in a position corresponding to the pressing member, and the side of the pressing member away from the first pressing plate can be provided in the relief groove.

[0018] When the second pressing piece holds the garment down, the clearance groove avoids the position of the seam bob, making it easy to adjust the seam bob. When the pressing piece holds the seam bob down, it is also easy to observe whether the seam bob has shifted.

[0019] Preferably, there are two second garment-pressing components, which are spaced apart horizontally. This increases the area where the garment is pressed down.

[0020] Preferably, the left and right moving device includes a left and right moving base and a left and right driving motor. The left and right moving base is slidably connected to the frame in the left and right direction. The left and right driving motor is disposed on the frame or the left and right moving base. The left and right moving base is drivenly connected to the left and right driving motor. The left and right moving base is the moving end of the left and right moving device.

[0021] Preferably, the first lifting and moving device includes a first lifting cylinder, a first slider, and a first guide rail. The cylinder body of the first lifting cylinder and the first slider are fixed on the left and right moving seats. The first guide rail extends in the vertical direction. The first slider is slidably connected to the first guide rail. The lower side of the first guide rail is fixedly connected to the first pressing plate. The piston shaft of the first lifting cylinder is fixedly connected to the first pressing plate.

[0022] The piston shaft of the first lifting cylinder, the first guide rail, and the first pressing plate extend to the lower side of the left and right moving seat. This reduces the height of the left and right moving seat and allows more space on the lower side of the left and right moving seat for adjusting the clothes and sewing.

[0023] Preferably, the processing platform is provided with a plurality of negative pressure holes that can generate negative pressure, and at least some of the negative pressure holes are located on the garment storage area.

[0024] When clothes are placed in the storage area, the negative pressure holes can create negative pressure to hold the clothes in place, making it easy to fix them in place after the clothes are positioned. Attached Figure Description

[0040] like Figures 1 to 9 As shown, an overlock sewing device includes a frame 1, an overlock sewing machine 2, and a first garment pressing assembly 3.

[0041] The frame 1 is equipped with a processing platform 11, which has a garment placement area 111 and a sewing area 112 arranged on the left and right sides. The surface of the processing platform 11 is relatively smooth, which reduces the friction between the processing platform 11 and the garment 9.

[0042] The overlock sewing machine 2 is fixed on the frame 1 and is located on the overlock sewing area 112. The overlock sewing machine 2 includes a sewing head for overlock sewing. When the garment 9 passes through the needle insertion area under the sewing head, the sewing head overlocks the garment 9.

[0043] The first garment pressing assembly 3 includes a left-right moving device 4, a first lifting moving device 5, a first garment pressing plate 6, and a pressing member 61. The left-right moving device 4 is mounted on the frame 1. The first lifting moving device 5 is mounted on the moving end of the left-right moving device 4. The first garment pressing plate 6 is mounted on the moving end of the first lifting moving device 5. The pressing member 61 is fixed to the first garment pressing plate 6. The left-right moving device 4 can drive the first lifting moving device 5, the first garment pressing plate 6, and the pressing member 61 to move left and right between the garment placement area 111 and the overlock sewing area 112. The first lifting moving device 5 can drive the first garment pressing plate 6 and the pressing member 61 to move up and down. The first garment pressing plate 6 can press the garment 9 onto the processing platform 11. The pressing member 61 is used to press down the seam bob 91. The first garment pressing plate 6 and the pressing member 61 are offset from the overlock sewing machine 2. In the front-back direction, the pressing member 61 is located on the side of the first garment pressing plate 6 closer to the overlock sewing machine 2.

[0044] The garment 9 to be overlocked is placed on the garment placement area 111 of the processing platform 11. The already overlocked seam allowance 91 is positioned to the correct side. The first pressing plate 6 is moved to the top of the garment 9, referring to... Figure 1 And the pressure plate 61 is located directly above the suture bone 91; then the first lifting and moving device 5 drives the first pressing plate 6 to move downward, and the first pressing plate 6 presses the garment 9 onto the processing platform 11, referring to... Figure 6Once the overlock edge 92 is exposed outside the first pressing plate 6, the pressing piece 61 presses down on the seam bob 91 to maintain the orientation of the seam bob 91, referring to... Figure 7 The pressure plate 61 does not press down on the edge 92 to be overlocked; then the left and right moving device 4 drives the first lifting moving device 5, the first pressing plate 6, and the pressure plate 61 to move towards one side of the overlocking machine 2 located in the overlocking area 112. Under the pressure and friction of the first pressing plate 6, the garment 9 moves towards the overlocking machine 2, as shown in the figure. Figure 9 The first pressing plate 6 passes in front of the overlock machine 2, and during the movement, the overlock machine 2 overlocks the edge 92 of the garment 9 to be overlocked.

[0045] This overlock sewing equipment uses a first pressure plate 6 to press down the garment 9 and move it towards the overlock sewing machine 2 for overlock sewing. In addition, the pressure plate 61 presses down the seam bob 91. The pressure plate 61 can be closer to the sewing position to prevent it from lifting up. This ensures that the direction of the seam bob 91 is kept on the required side during the movement of the garment 9 and the overlock sewing process, improving the safety of manual operation.

[0046] In some specific embodiments, reference is made to Figure 5 The lower side of the bone pressing component 61 is provided with a puncture needle 611, which is used to puncture the bone 91.

[0047] When the pressure plate 61 presses down on the seam bob 91, the piercing needle 611 will pierce into the seam bob 91. The piercing needle 611 can further stabilize the position of the seam bob 91 and further keep the orientation of the seam bob 91 on the desired side, especially in positions similar to the armpit of a sleeve. There are seam bobs 91 on the upper and lower sides of the garment 9 and the edge 92 to be sewn. It is required that the upper and lower seam bobs 91 are oriented to the same side. The piercing needle 611 will pass through the two seam bobs 91 vertically. Refer to Figure 8 This ensures that the positions of the two suture bones 91 do not protrude. When the puncture needle 611 is inserted into the suture bone 91, manual pressure can be used to assist in its insertion.

[0048] Furthermore, the processing platform 11 is equipped with a needle-sewing mechanism 12, as shown in the reference. Figure 3 The slit 12 extends left and right between the garment placement area 111 and the overlock area 112, with the lower end of the piercing needle 611 positioned within the slit 12. The length of the slit 12 matches the movement of the garment 9.

[0049] When the lower end of the puncture needle 611 passes through the suture bone 91, the connection stability between the puncture needle 611 and the suture bone 91 can be improved. Therefore, the needle slit 12 is set so that the lower end of the puncture needle 611 can pass through the suture bone 91 and the clothing 9 and enter the needle slit 12, so as to prevent the processing platform 11 from pressing against the puncture needle 611.

[0050] In some embodiments, the pressure member 61 is fixed to the first pressure plate 6 by screws. The first pressure plate 6 has a plurality of mounting screw holes 62 arranged in a left-right direction, allowing the pressure member 61 to be adjusted to connect to suitable mounting screw holes 62 as needed.

[0051] In some specific embodiments, the overlock sewing equipment also includes a second garment pressing assembly 7, which is located on the upper side of the garment placement area 111. The second garment pressing assembly 7 includes a second lifting and moving device 71 and a second garment pressing component 72. The second lifting and moving device 71 is located on the frame 1, and the second garment pressing component 72 is located on the moving end of the second lifting and moving device 71. The second lifting and moving device 71 can drive the second garment pressing component 72 to move up and down. In the front-back direction, the second garment pressing assembly 7 is located on the side of the first garment pressing assembly 3 closer to the overlock sewing machine 2. The second garment pressing component 72 can press the garment 9 onto the processing platform 11. The first garment pressing plate 6 and the second garment pressing component 72 are arranged in a front-back arrangement.

[0052] When placing garment 9 on the garment storage area 111, one side of the edge 92 to be overlocked can be laid flat and arranged under the second pressing piece 72. The second lifting and moving device 71 moves the second pressing piece 72 downward to press down and fix the edge 92 to be overlocked on the garment 9. Space can be left under the first pressing plate 6 for manual adjustment of the orientation of garment 9 and seam boning 91. After adjustment, the first pressing plate 6 presses down on garment 9, and the pressing piece 61 presses down on seam boning 91. (Refer to...) Figure 7 Then, the second lifting and moving device 71 drives the second pressing component 72 to rise and leave the garment 9, leaving the edge 92 to be overlocked. The first pressing plate 6 then moves the garment 9 toward the overlocking machine 2. By setting the second pressing component 7, the position of the garment 9 and the seam boning 91 can be manually adjusted, making the positioning of the garment 9 and the overlocking position more accurate. The second lifting and moving device 71 can be a cylinder.

[0053] Furthermore, the second pressing member 72 is provided with a relief groove 721, which is positioned corresponding to the pressing member 61. The side of the pressing member 61 that is away from the first pressing plate 6 can be located in the relief groove 721.

[0054] When the second pressing piece 72 presses down on the garment 9, the second pressing piece 72 presses down on the area near the intersection of the seam bob 91, so that the nearby position does not shift when the seam bob 91 is adjusted. The avoidance groove 721 avoids the position of the seam bob 91, which makes it easy to adjust the seam bob 91. When the pressing piece 61 presses down on the seam bob 91, it is also easy to observe whether the seam bob 91 has shifted.

[0055] In some specific embodiments, there are two second garment-pressing components 7, which are spaced apart from each other. This increases the number of positions that press down on the garment 9 along the length of the edge 92 to be overlocked.

[0056] In some specific embodiments, the left and right moving device 4 includes a left and right moving seat 41 and a left and right driving motor 42. The left and right moving seat 41 is located above the processing platform 11. The left and right moving seat 41 is slidably connected to the frame 1 in the left and right direction. The left and right driving motor 42 is mounted on the frame 1 or the left and right moving seat 41. The left and right moving seat 41 is connected to the left and right driving motor 42 in a transmission manner. The left and right moving seat 41 is the moving end of the left and right moving device 4.

[0057] Furthermore, a second guide rail 14 extending in the left-right direction is fixed on the frame 1, and a second slider is slidably connected to the second guide rail 14. The left-right moving seat 41 is fixedly connected to the second slider. The left-right drive motor 42 is fixed on the frame 1, and a drive pulley is fixedly connected to the shaft of the left-right drive motor 42. A driven pulley is provided on the other side of the frame 1. A synchronous belt is wound around the drive pulley and the driven pulley. The synchronous belt is connected to the left-right moving seat 41 and drives the left-right moving seat 41 to move left and right. In some other embodiments, the left-right drive motor 42 can also be fixed on the left-right moving seat 41, and a gear is fixed on the shaft of the left-right drive motor 42. A rack is fixed on the frame 1, and the gear and rack mesh to drive the left-right moving seat 41 to move. The left-right drive motor 42 can also drive the left-right moving seat 41 to move through a motion mechanism such as a lead screw.

[0058] In some specific embodiments, the first lifting and moving device 5 includes a first lifting cylinder 51, a first slider 52 and a first guide rail 53. The cylinder body of the first lifting cylinder 51 and the first slider 52 are fixed on the left and right moving seats 41. The first guide rail 53 extends in the vertical direction. The first slider 52 is slidably connected to the first guide rail 53. The lower side of the first guide rail 53 is fixedly connected to the first pressing plate 6. The piston shaft of the first lifting cylinder 51 is fixedly connected to the first pressing plate 6.

[0059] The piston shaft of the first lifting cylinder 51, the first guide rail 53, and the first pressing plate 6 extend to the lower side of the left and right moving seat 41. This reduces the height of the left and right moving seat 41, allowing more space under the left and right moving seat 41 for adjusting the garment 9 and the seam boning 91. The first lifting cylinder 51 uses air pressure as its power source. After pressing down on the garment 9, it stops moving and maintains the pressure on the garment 9. The structure is relatively simple, and the force pressing down on the garment 9 can be adjusted by adjusting the air pressure. In other embodiments, the first lifting moving device 5 can also use a lead screw, gear rack, or other moving mechanism.

[0060] In some specific embodiments, reference is made to Figure 3 The processing platform 11 is provided with a plurality of negative pressure holes 13 that can generate negative pressure, and at least some of the negative pressure holes 13 are located on the clothing storage area 111.

[0061] When the garment 9 is placed on the garment placement area 111, the negative pressure hole 13 can generate negative pressure to hold the garment 9 in place, thus facilitating its fixation after adjustment. When the first pressure plate 6 moves the garment 9, the negative pressure of the negative pressure hole 13 can be closed to release the garment 9. A negative pressure pipe is provided on the lower side of the processing platform 11, which is connected to a negative pressure device. Multiple negative pressure holes 13 are connected to the negative pressure channel to generate negative pressure.

[0062] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
