Description

Technical Field

[0001] This utility model relates to a sewing device for forming loops of webbing, and more particularly to a webbing marking device for elastic waistbands in clothing. Background Technology

[0002] In the field of clothing production, belts are a common garment component, and the quality of their connection with the garment directly affects the comfort and overall shape of the garment. Currently, most garment belts on the market are made of elastic material, while the garment itself is mostly made of non-elastic fabric. The difference in the material properties of the two places strict requirements on the sewing process. If the elasticity of the belt is not evenly distributed, problems such as local wrinkles and inconsistent tightness may occur after sewing, which seriously affects the wearing experience and appearance quality of the garment. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a webbing marking device for elastic waistbands of clothing.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A webbing marking device for elastic waistbands in clothing includes a base plate mounted on a feeding mechanism of a sewing machine for looping webbing. A slide rail is mounted on the base plate, and at least one mounting seat is adjustablely mounted on the slide rail. A cylinder is mounted on the mounting seat, and a telescopic seat is mounted on the telescopic shaft of the cylinder. A swing arm for lowering or lifting a marking pen is hinged to the telescopic seat. A compression spring for pushing the swing arm to swing is installed between the upper side of the swing arm and the telescopic seat. A limiting part is provided on the mounting seat that abuts against the lower side of the swing arm.

[0005] The swing arm has an upper inclined part and a lower inclined part on the side near the telescopic seat. The compression spring is installed between the upper inclined part and the telescopic seat, and the lower inclined part abuts against the limiting part.

[0006] The swing arm is equipped with a rotatable and adjustable clamping seat, which has a first through hole for inserting the marker pen and a hand screw for fixing the marker pen.

[0007] The swing arm is equipped with a mounting shaft, and the clamping seat is provided with a mounting hole corresponding to the mounting shaft, and the mounting shaft is rotatably installed in the mounting hole.

[0008] The cylinder is mounted on a fixed seat, and the telescopic seat is provided with an adjusting seat corresponding to the fixed seat. The fixed seat is provided with a second through hole along the direction of the adjusting seat, and an adjusting screw is provided in the second through hole. The end of the adjusting screw is threaded onto the adjusting seat.

[0009] The base plate is provided with scale markings along the length of the slide rail.

[0010] A slider is fixed to the bottom of the mounting base, and the slider is slidably mounted on the slide rail.

[0011] The beneficial effects of this utility model are as follows: A slide rail is installed on the base plate, and at least one mounting seat is adjustablely mounted on the slide rail. A cylinder is mounted on the mounting seat, and a telescopic seat is mounted on the telescopic shaft of the cylinder. A swing arm for lowering or raising the marker pen is hinged to the telescopic seat. A compression spring for pushing the swing arm to swing is installed between the upper side of the swing arm and the telescopic seat. A limiting part is provided on the mounting seat that abuts against the lower side of the swing arm. During operation, the cylinder extends, causing the swing arm to disengage from the limiting part, and the compression spring pushes the swing arm downward to lower the pen, allowing marking lines to be drawn on the webbing. When the cylinder retracts, after the swing arm abuts against the limiting part, the limiting part pushes the swing arm upward to raise the pen, preventing the webbing from contacting the marker pen during feeding. This allows for precise and stable marking on elastic waistbands, providing a positioning reference for precise sewing of elastic waistbands and non-elastic garment bodies. It effectively solves the problems of local wrinkles and inconsistent tightness in garments after sewing, improving garment production quality and efficiency. Attached Figure Description

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0015] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0016] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0017] Reference Figure 1-5A webbing marking device for elastic waistbands in clothing includes a base plate 1 mounted on the feeding mechanism of a sewing machine for looping webbing. A slide rail 2 is mounted on the base plate 1. A slider 19 is fixed to the bottom of a mounting base 3 and slidably mounted on the slide rail 2. At least one mounting seat 3 is adjustablely mounted on the slide rail 2. A cylinder 4 is mounted on the mounting seat 3. A telescopic seat 5 is mounted on the telescopic shaft of the cylinder 4. A swing arm 6 for lowering or lowering a marking pen 9 is hinged to the telescopic seat 5. A compression spring 7 for pushing the swing arm 6 to swing is installed between the upper side of the cylinder 4 and the telescopic seat 5. A limiting part 8 is provided on the mounting seat 3 to abut against the lower side of the swing arm 6. Through the extension and retraction of the cylinder 4, the swing arm 6, in conjunction with the compression spring and the limiting part 8, enables the marking pen 9 to be put down or lifted, which can accurately and stably complete the marking on the elastic waistband of the garment. This provides a positioning reference for the precise sewing of the elastic waistband and the non-elastic garment body, effectively solving the problem of local wrinkles and inconsistent tightness of the garment after sewing, and improving the quality and efficiency of garment production.

[0018] The swing arm 6 is provided with an upper inclined part 10 and a lower inclined part 11 on the side near the telescopic seat 5. The compression spring 7 is installed between the upper inclined part 10 and the telescopic seat 5. The lower inclined part 11 abuts against the limiting part 8. The upper inclined part 10 and the lower inclined part 11 are provided to provide sufficient space for the swing arm 6 to swing.

[0019] The swing arm 6 is equipped with a rotatable and adjustable clamping seat 12. The clamping seat 12 is provided with a first through hole 13 for passing the marker pen 9 through. The clamping seat 12 is equipped with a hand screw 14 for fixing the marker pen 9. When installing the marker pen 9, after passing the marker pen 9 through the first through hole 13, the hand screw 14 is tightened. The end of the hand screw 14 abuts against the marker pen 9 and presses it against the inner wall of the first through hole 13, thereby fixing the marker pen 9.

[0020] The swing arm 6 is equipped with a mounting shaft 20, and the clamping seat 12 is provided with a mounting hole corresponding to the mounting shaft 20. The mounting shaft 20 is rotatably installed in the mounting hole. Through the cooperation between the mounting hole and the mounting shaft 20 (the swing arm 6, the clamping seat 12 and the mounting shaft 20 are all locked with screws. After adjustment, the screws are screwed in, and the end of the screw will press the mounting shaft 20 tightly. In actual operation, the screw between the swing arm 6 and the mounting shaft 20 is always fixed. When adjusting the clamping seat 12, it is only necessary to adjust by loosening or tightening the screw between the clamping seat 12 and the mounting shaft 20), the clamping seat 12 can be rotated to adjust the angle between the marking pen 9 and the vertical direction, that is, to adjust the contact area between the marking pen 9 and the webbing. The larger the contact area, the thicker the line; conversely, the smaller the contact area, the thinner the line. In addition, the marking pen 9 can also be adjusted to avoid collision with other structures of the sewing equipment, thereby improving its flexibility.

[0021] The cylinder 4 is mounted on a fixed seat 15. The telescopic seat 5 is provided with an adjusting seat 16 corresponding to the fixed seat 15. The fixed seat 15 is provided with a second through hole 17 along the direction of the adjusting seat 16. An adjusting screw 18 is provided in the second through hole 17. The end of the adjusting screw 18 is threaded onto the adjusting seat 16. The head size of the adjusting screw 18 is larger than the second through hole 17. When the cylinder 4 extends, the telescopic seat 5 slides outward. The adjusting seat 16 and the adjusting screw 18 move synchronously. When the head of the adjusting screw 18 contacts the fixed seat 15, the telescopic seat 5 can no longer slide, thereby limiting the limit distance of the extension of the cylinder 4, that is, controlling the length of the mark drawn by the marking pen 9.

[0022] The base plate 1 is provided with a scale along the length of the slide rail 2. The position of the marking pen can be adjusted by the scale to improve the marking accuracy on the webbing, ensure the precise sewing of the loop tape to the garment, and avoid the problem of uneven elasticity of the loop tape.

[0023] The first method of using this device: The extension limit of the cylinder 4 is greater than the length by which the lower side of the swing arm 6 disengages from the limiting part 8: The cylinder 4 extends to the lower side of the swing arm 6 and disengages from the limiting part 8. The compression spring 7 pushes the swing arm 6 to swing downward, thereby causing the marking pen 9 to swing synchronously, achieving the effect of writing. At this time, the cylinder 4 continues to extend, and the marking pen 9 can draw a line mark on the webbing. When the cylinder 4 retracts, the marking pen 9 will draw a line in the same position (that is, a line will be drawn in both reciprocating strokes. During this process, the webbing will not be conveyed. That is, two lines are drawn in the same position, which only makes the color of the line mark clearer) until the lower side of the swing arm 6 abuts against the limiting part 8. The limiting part 8 will push the swing arm 6 to swing upward, thereby causing the marking pen 9 to swing synchronously, achieving the effect of lifting the pen.

[0024] The second way to use this device: The extension limit of the cylinder 4 is equal to the length by which the lower side of the swing arm 6 disengages from the limiting part 8: When the cylinder 4 extends to its limit, the lower side of the swing arm 6 just disengages from the limiting part 8, and the compression spring 7 pushes the swing arm 6 to swing downward, so that the marking pen 9 swings synchronously, achieving the effect of writing and drawing a dot on the webbing, that is, drawing a dot-shaped mark. When the cylinder 4 retracts, the marking pen 9 can be lifted.

[0025] Furthermore, for the second usage method, the maximum extension length of the telescopic seat 5 can be increased slightly (e.g., 1-5 mm) to make the dot markings clearer.
