Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology, and more specifically, it relates to a sewing guide structure for textile bags. Background Technology

[0002] Reflective vests (also known as high-visibility warning vests) are personal protective equipment (PPE) used to improve the wearer's visibility in low-light or hazardous environments. They are widely used in transportation, construction, sanitation, emergency rescue and other fields.

[0003] Current reflective vests are typically made by sewing reflective strips onto a fluorescent fabric. The entire bundle of reflective strips needs to be pulled onto a sewing machine to sew them onto the vest, with any excess trimmed off. However, the rolled-up reflective strips are quite long and narrow, and tend to curl inwards on both sides when being pulled out, resulting in missed stitches. This requires manual inspection to check for folds and curls and straighten them, increasing the workload for workers.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a sewing guide structure for textile bags in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a sewing guide structure for textile bags, which solves the problem that reflective strips tend to curl inwards on both sides when sewing, resulting in empty stitches and requiring manual observation to check for folding and straightening, thus increasing the workload of workers.

[0006] The purpose and function of this utility model's sewing guide structure for textile bags are achieved through the following specific technical means:

[0007] A sewing guide structure for textile bags includes a presser foot consisting of a base and an mounting head. The base has a through hole for thread passing through. A guide piece is connected to one end of the base. The guide piece is inclined upwards. A triangular paddle is provided at the front end of the guide piece. The triangular paddle is connected to the guide piece through a connecting frame. Two triangular paddles are arranged in parallel. A strip of fabric passes through the gap between the two triangular paddles, and the two sides of the two triangular paddles are connected by a connecting strip.

[0008] Furthermore, inner buckle plates are connected to both sides of the guide plate, and the inner buckle plates are bent below the guide plate.

[0009] Furthermore, support plates are symmetrically installed on both sides of the guide plate, and Y-shaped supports extend from the edges of the support plates. Guide rollers are rotatably connected between the supports on the corresponding support plates.

[0010] Furthermore, the guide plate is provided with a support plate, and the support plate is mounted on the support plate and connected to it by bolts.

[0011] Furthermore, the connection between the base and the guide plate is arc-shaped.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The presser foot is installed on the sewing machine head via the mounting head. The base presses down on the vest. The reflective strip that is pulled in is combed by the triangular pick, and the two sides that were rolled inward are gradually flattened and attached to the guide plate before entering under the base to wait for sewing. The reflective strip can be prevented from rolling inward without human intervention, thus avoiding empty needles. Attached Figure Description

[0021] Example:

[0022] As attached Figure 1 To be continued Figure 2 As shown:

[0023] This utility model provides a sewing guide structure for textile bags, including a presser foot composed of a base 1 and a mounting head 3. The presser foot is connected to the sewing machine head through the mounting head 3. The base 1 is responsible for pressing down the fabric to be sewn, such as pressing down the vest when making a reflective vest.

[0024] The base 1 has a through hole 2 for threading, which is used for sewing machine to thread the needle. One end of the base 1 is connected to a guide plate 4. The guide plate 4 is set at an upward angle. The guide plate 4 can guide the reflective fabric strip from the outside to the bottom of the base 1 and sew it with the vest.

[0025] The front end of the guide plate 4 is provided with a triangular lever 9, which is connected to the guide plate 4 through the connecting frame 8. There are two triangular levers 9 arranged in parallel, with a strip of cloth passing through the gap between the two triangular levers 9. The two sides of the two triangular levers 9 are connected by a connecting strip 10. The reflective cloth strip passes smoothly between the two triangular levers 9 and then enters the guide plate 4. The arrangement of the triangular levers 9 causes the curved and inwardly rolled reflective cloth strip to contact the triangular levers 9 from the inside first. During the movement, the contact area between the two sides of the triangular levers 9 and the reflective cloth strip gradually increases, and the cloth strip is smoothed, so that it is automatically straightened without human intervention.

[0026] During the process of the reflective strip entering the guide plate 4, inner buckle plates 401 are connected to both sides of the guide plate 4. The inner buckle plates 401 are bent below the guide plate 4. The inner buckle plates 401 restrict the reflective strip so that it does not curl inward during the entire process of entering the base 1, making it flatter. At the same time, support plates 5 are symmetrically installed on both sides of the guide plate 4. Y-shaped supports 6 extend from the edges of the support plates 5. Guide rollers 7 are rotatably connected between the supports 6 on the corresponding support plates 5. The two guide rollers 7 clamp the reflective strip, so that the reflective strip enters the guide plate 4 and the inner buckle plates 401 more smoothly. The rolling of the guide rollers 7 can also squeeze the reflective strip, making its surface flat and wrinkle-free.

[0027] The guide plate 4 is provided with a support plate 402, and the support plate 5 is installed on the support plate 402 and connected to it by bolts. The support plate 402 increases the thickness of a part of the guide plate 4 so that the bolts will not pass through the guide plate 4 and affect the movement space of the reflective strip. At the same time, the support plate 5 can be disassembled.

[0028] As the reflective strip enters the base 1 from the guide plate 4, the connection between the base 1 and the guide plate 4 is arc-shaped to avoid creases forming at the turning point of the reflective strip.

[0029] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
