Description

Technical Field

[0001] This utility model relates to the field of swimwear processing technology, specifically to a hemming and sewing device for swimwear processing. Background Technology

[0002] In the sewing process of swimsuits, in order to ensure the product is comfortable to wear, aesthetically pleasing, and the seams are strong, it is often necessary to hem the edges of the fabric. Currently, this process mainly relies on manual operation, that is, the operator needs to manually roll up the side of the swimsuit fabric according to the process requirements to form the hem to be sewn, and then guide it to the presser feet of the sewing machine for sewing.

[0003] However, in practice, the hemming process relies entirely on the worker's skill and experience. Workers need to master certain techniques to ensure that the hemmed width is uniform and the tension is appropriate. This purely manual operation method has obvious drawbacks: the hemming quality is unstable, and differences may occur between different workers or even the same worker at different times, easily leading to problems such as inconsistent hemmed width and fabric distortion, which seriously affects the appearance quality and grade of the finished swimsuit. To address this, we propose a hemming and sewing device for swimsuit processing. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hemming and sewing device for swimsuit processing, comprising: a base, a placement groove formed at the rear edge of the top of the base, mounting blocks fixed at the front and rear edges of the placement groove, a circular hole formed in the middle of the mounting blocks and the placement groove, a rotating shaft rotatably connected to the circular hole via a bearing, a motor fixed at the rear end of the rotating shaft, a rotating plate fixed to the shaft body of the rotating shaft, a fixing block fixed at the right edge of the rotating plate, and two sets of fixing blocks symmetrically arranged at the bottom end of the fixing blocks. A fixed ring is provided, with a support shaft fixed at its central hole. A rotary spring is fitted on the middle of the shaft of the support shaft, and rotary rings are fitted at both ends of the shaft. A limit plate is fixed to the bottom of the rotary rings. A side mounting plate is fixed at the front edge of the top of the base. A guide groove is provided in the middle of the right side of the side mounting plate. A lead screw is rotatably connected to the inside of the guide groove through a bearing. A knob is fixed at the top of the lead screw. A slider is threadedly connected to the shaft of the lead screw. A pressure roller is provided on the right side of the slider.

[0005] As a preferred embodiment of this utility model, one end of the rotary spring abuts against the outer wall of the fixed block, and the other end abuts against the outer wall of the limiting plate.

[0006] As a preferred embodiment of this utility model, the limiting plate is inclined, and its bottom end abuts against the included angle of the rotating plate and the base.

[0007] As a preferred embodiment of this utility model, scales are provided on both sides of the rotating plate.

[0008] As a preferred embodiment of this utility model, the right side of the side mounting plate is flush with the right side of the rotating plate.

[0009] In a preferred embodiment of this invention, the slider is fitted with the guide groove, and the slider is slidably connected to the guide groove.

[0010] As a preferred embodiment of this utility model, the front end of the pressure roller is provided with a needle groove at the top of the base.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) Improve the stability and accuracy of the hem stitching quality: This device achieves visual and precise positioning of the hem width through a scale. Combined with the elastic fixation of the limiting plate and the 90-degree folding mechanism, it ensures that the hem width of each batch of swimsuits is consistent and the shape is standard. At the same time, the flush design of the side mounting plate and the rotating plate avoids the fabric from twisting during the process, which significantly improves the appearance quality and grade of the finished product and reduces the defect rate.

[0013] (2) Reduce reliance on manual labor and improve processing efficiency: The device integrates visual positioning, automatic folding and automatic pressing functions. There is no need for workers to manually complete the edge positioning and folding operations. Only simple equipment start-up and parameter adjustment are required to complete the operation, which greatly reduces the reliance on workers' operating skills and reduces manual operation steps and labor intensity.

[0014] (3) Ensure the stability of the sewing process and improve the firmness of the seam: The rolling and pressing of the roller at the rolled edge can ensure that the rolled edge shape does not loosen or shift during the sewing process, so that the sewing needle can accurately sew along the needle groove, avoiding problems such as misalignment of the sewing thread and missing stitches caused by the displacement of the rolled edge, significantly improving the firmness of the swimsuit seam and extending the product's service life.

A slider 19 is threadedly connected to the body of the lead screw 17. A pressure roller 20 is provided on the right side of the slider 19.

[0025] In order to enable the limiting plate 11 to have the ability to automatically reset, it can automatically press down by the spring force after being lifted, forming a stable and appropriate elastic pressing force on the edge of the swimsuit fabric, so as to prevent the fabric from shifting during the subsequent rotation and hemming of the rotating plate 6, and at the same time prevent rigid pressing from damaging the fabric. In this embodiment, as a preferred technical solution of the present invention, one end of the rotating spring 12 abuts against the outer side wall of the fixing block 7, and the other end abuts against the outer side wall of the limiting plate 11.

[0026] In order to ensure that the bottom end of the limiting plate 11 can precisely abut against the angle between the rotating plate 6 and the base 1 during the process of rotating the plate 6 from horizontal to perpendicular to the base 1, and thus guide the edge of the swimsuit fabric to automatically fold into a standardized rolled edge shape with the bottom end of the limiting plate 11 as the fulcrum, without the need for manual adjustment of the folding angle, and to ensure that the rolled edge angle is consistent for each batch, in this embodiment, as a preferred technical solution of the present invention, the limiting plate 11 is set in an inclined position, and its bottom end abuts against the angle between the rotating plate 6 and the base 1.

[0027] In order to provide operators with a visual positioning reference for the hem width, so that operators can accurately align the edge of the swimsuit fabric to the corresponding scale line according to the different hem widths required by the process, avoid the deviation of the hem width caused by manual estimation, and achieve standardized control of the hem width, in this embodiment, as a preferred technical solution of the present invention, scales 13 are provided on both sides of the rotating plate 6.

[0028] In order to ensure that the swimsuit fabric travels in a straight line from the rotating plate 6 to the pressure roller 20, and to avoid the fabric shifting or twisting during the conveying process due to uneven edges, thereby ensuring the accurate position of the seam during subsequent sewing and improving the sewing quality, in this embodiment, as a preferred technical solution of the present invention, the right side of the side mounting plate 15 is flush with the right side of the rotating plate 6.

[0029] In order to limit the movement direction of the slider 19 and ensure that the slider 19 moves vertically up and down along the guide groove 16 under the drive of the lead screw 17, so as to avoid the slider 19 from shifting laterally or rotating, and thus ensure that the pressure roller 20 can stably adjust the height and accurately form a pressing force on the rolled edge of the swimsuit, in this embodiment, as a preferred technical solution of the present invention, the slider 19 fits into the guide groove 16 and the slider 19 is slidably connected to the guide groove 16.

[0030] In order to provide a dedicated travel channel for the sewing needle of the sewing equipment, and to ensure that the sewing needle can sew the rolled edge of the swimsuit after being pressed by the pressure roller 20 along a fixed path, so as to avoid interference between the sewing needle and other parts of the device, and at the same time ensure that the stitch position is neat and accurate, and improve the sewing effect, in this embodiment, as a preferred technical solution of the present invention, the front end of the pressure roller 20 is provided with a needle groove 14 at the top of the base 1.

[0031] In summary, with the help of the above-described technical solution of this utility model,

[0032] Working Principle: In the initial state, the rotating plate 6 is placed horizontally in the placement groove 2 on the rear side of the top of the base 1, ensuring the stability of the fabric placement space in the initial state. When the hem-rolling operation is required, the operator first lifts the limiting plate 11 upwards. Since the limiting plate 11 is sleeved on the shaft of the support shaft 9 through the rotating ring 10, and the support shaft 9 is fixed to the bottom of the fixing block 7 through the fixing ring 8, the lifting action can drive the rotating ring 10 to rotate along the support shaft 9, while compressing the rotating spring 12 sleeved in the middle of the support shaft 9. At this time, one end of the rotating spring 12 abuts against the outer wall of the fixing block 7, and the other end abuts against the outer wall of the limiting plate 11, providing elasticity for subsequent reset. Then, the edge of the swimsuit fabric to be hemmed is placed on the surface of the rotating plate 6. Using the scale 13 on both sides of the rotating plate 6, the edge of the fabric is aligned with the corresponding scale line according to the hem width required by the process, achieving precise pre-positioning of the hem width. After positioning is completed, the limiting plate 11 is released. Under the reset force of the rotating spring 12, the limiting plate 11 automatically presses down to elastically fix the edge of the swimsuit fabric.

[0033] The motor 5 on the rear side of the base 1 is started. The output shaft of the motor 5 drives the rotating shaft 4 fixed to it to rotate. The rotating plate 6 fixed to the shaft of the rotating shaft 4 rotates synchronously until the rotating plate 6 rotates from a horizontal state to a vertical state perpendicular to the base 1. During this process, the bottom end of the limiting plate 11, which is set at an inclination, gradually abuts against the angle formed by the rotating plate 6 and the base 1. At this time, the edge of the swimsuit fabric automatically folds to form a rolled edge shape of less than 90 degrees with the bottom end of the limiting plate 11 as the fulcrum. No manual folding is required, and the rolled edge shape is standardized. The front end of the folded swimsuit rolled edge is moved to the bottom of the pressure roller 20. Since the side mounting plate 15 is fixed to the front edge of the top of the base 1, and the right side of the side mounting plate 15 is flush with the right side of the rotating plate 6, it can be ensured that the swimsuit fabric travels in a straight line when transitioning from the rotating plate 6 to the pressure roller 20, effectively avoiding fabric twisting. The operator rotates the knob 18 at the top of the lead screw 17, causing the lead screw 17 to rotate within the guide groove 16 in the middle of the right side of the side mounting plate 15. Because the slider 19 is threadedly connected to the lead screw 17, and the slider 19 is fitted and slidably connected to the guide groove 16, the rotation of the lead screw 17 drives the slider 19 to move up and down along the guide groove 16, thereby adjusting the height of the pressure roller 20 connected to the slider 19 until the pressure roller 20 applies appropriate rolling pressure to the rolled edge of the swimsuit, ensuring the rolled edge remains stable during the sewing process. Finally, the sewing needle of the sewing equipment moves along the needle groove 14 at the top of the base 1, positioned at the front end of the pressure roller 20, completing the precise sewing of the rolled edge. The motor model mentioned above is a servo motor LW-200 / 60. This servo motor has a built-in controller with functions such as speed adjustment, direction adjustment, and programming. The above motor model is for reference only and should meet the work requirements.
