Description

Technical Field

[0001] The utility model relates to the technical field of binding strap production, in particular to a binding strap label sewing mechanism. Background Art

[0002] Sewing tie labels is a common and critical process in the manufacturing of clothing, luggage, and other products. Traditionally, this process relies on manual labor, requiring workers to manually place the tie labels on the sewing machine and constantly adjust their position to ensure they are sewn precisely onto the label. This method is not only inefficient but also prone to human error, resulting in inconsistent product quality.

[0003] In order to improve production efficiency and product quality, the industry has developed some automated strap label sewing equipment. For example, the prior art uses a clamp to fix the strap, and a robotic arm is used to deliver the strap to the sewing station. However, this method still has the problem of inaccurate positioning when handling soft or thin straps, and the opening and closing action of the clamp increases the complexity and failure rate of the mechanism. Another common method is to use a vacuum suction cup to fix the strap. Although this method can fix the strap well, the vacuum suction cup often blocks the sewing area, affecting the sewing operation. In addition, the suction force of the vacuum suction cup is difficult to distribute evenly, which may cause local deformation of the strap, affecting the sewing quality.

[0004] Some designs use a conveyor system to transport the straps, and use positioning pins or photoelectric sensors to position them at the sewing station. Although this method improves the level of automation, it is complex and difficult to debug, and it is difficult to adapt to straps of different sizes and materials.

[0005] Therefore, the industry still lacks a simple, efficient, and adaptable strap label sewing mechanism that can simultaneously solve the problems of automatic strap delivery, precise positioning, and secure fixation. Existing technologies often struggle to achieve both efficiency and precision when processing straps of various materials and sizes. Utility Model Content

[0028] The present invention will be further described below with reference to specific embodiments. It should be understood that the following specific embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0029] Example 1: See Figure 1-6 In order to achieve the above objectives, the present application discloses a strap label sewing mechanism, which specifically includes:

[0030] The sewing machine body 1 includes the basic functional components of the sewing machine, such as the needle, the cloth feeding mechanism, etc. In this embodiment, a pneumatic clamp is used to transport the tape label to be sewn;

[0031] A turntable 2 is rotatably mounted at the sewing station of the sewing machine body 1 via a bearing;

[0032] A plurality of placement slots 3 are provided on the turntable 2 ; they can specifically match the shape of the straps. In this embodiment, three placement slots 3 are provided, and the three placement slots 3 are distributed on the turntable 2 at equal intervals.

[0033] A plurality of cavities 4 are independently formed inside the turntable 2, and each cavity 4 corresponds to a placement slot 3;

[0034] A plurality of adsorption holes 5 are provided on the bottom surface of each placement slot 3, and the adsorption holes 5 are connected to the corresponding cavity 4;

[0035] An avoidance groove 6 is provided in the placement groove 3 and is used to avoid the needle head of the sewing machine body 1;

[0036] A plurality of arc-shaped slots 7 are provided at the bottom of the turntable 2, each arc-shaped slot 7 is connected to a cavity 4, and the plurality of arc-shaped slots 7 are surrounded to form a ring shape;

[0037] The air extraction hole 8 is provided at the bottom of the turntable 2 corresponding to the sewing station and is located on the rotation track of the arc-shaped slot 7.

[0038] When the turntable 2 rotates, the arc-shaped slot hole 7 gradually passes through the exhaust hole 8, and the air in the cavity 4 is extracted through the exhaust hole 8 to form a negative pressure, so that the adsorption hole 5 can adsorb the strap placed in the placement slot 3; when the arc-shaped slot hole 7 passes over the exhaust hole 8, the cavity 4 is disconnected from the exhaust hole 8, and the adsorption state of the adsorption hole 5 in the placement slot 3 is released, so that the strap in the placement slot 3 can be taken out.

[0039] Specifically, the process includes the following:

[0040] Preparation stage: Place the strap in the placement slot 3 of the turntable 2;

[0041] Adsorption stage: When the turntable 2 rotates, the arc-shaped groove 7 gradually passes through the exhaust hole 8. At this time, the exhaust device extracts the air in the cavity 4 through the exhaust hole 8, forming a negative pressure. The negative pressure is transmitted to the placement groove 3 through the adsorption hole 5, thereby firmly adsorbing the strap in the placement groove 3.

[0042] Sewing stage: Turntable 2 rotates the strap to the sewing station. The sewing machine needle passes through the avoidance groove 6 to sew the label onto the strap.

[0043] Release stage: After sewing is completed, the arc groove 7 continues to rotate and passes over the air extraction hole 8. At this time, the cavity 4 is disconnected from the air extraction hole 8, the negative pressure disappears, and the adsorption hole 5 in the placement groove 3 loses its adsorption force, making it easier to remove the sewn strap.

[0044] Circular operation: the turntable 2 continues to rotate, the next placement slot 3 arrives at the sewing station, and the above process is repeated.

[0045] The avoidance groove 6 is provided at the center of the placement groove 3, and the adsorption holes 5 are provided in at least two rows, and the two rows of adsorption holes 5 are arranged at the two side edges of the placement groove 3. The two rows of adsorption holes 5 are arranged at the two side edges of the placement groove 3, which can better fix the two sides of the strap, prevent the strap from being deformed or displaced during sewing, and further improve the sewing quality.

[0046] The strap label sewing mechanism further includes a driving device 9 for driving the turntable 2 to rotate intermittently. The driving device 9 can be a stepper motor or a servo motor, which is connected to the turntable 2 through a gear or a belt.

[0047] The device also includes an air extraction device 10 connected to the air extraction hole 8 for generating negative pressure. The air extraction device 10 can be a vacuum pump or a negative pressure generator.

[0048] In this embodiment, the rotation of the turntable 2 and the coordination of the suction mechanism enable automatic conveying and securing of the straps, significantly improving production efficiency. The suction mechanism securely holds the straps in place, preventing them from shifting during the sewing process and enhancing sewing precision. The operator simply places the straps into the placement slot 3, and the rest of the process is automatically completed, reducing operational difficulty and labor intensity.

[0049] Embodiment 2: The two side walls of the placement groove 3 are inclined surfaces that gradually approach each other from top to bottom.

[0050] The placement groove 3 is made to be in an inverted trapezoidal or V-shaped shape as a whole. Due to the inclined design of the two side walls, the strap will automatically center under the action of gravity, forming a stable V-shaped posture.

[0051] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
