Description

Technical Field

[0001] This utility model relates to the field of swing mechanism technology, and in particular to a worm gear synchronous belt correction device. Background Technology

[0002] The worm gear synchronous belt correction device mainly consists of a feeding device, a folding mechanism, a sewing mechanism, a control system, and a machine frame. The feeding device accurately delivers the fabric to the working area, equipped with adjustable rollers and sensors to adapt to fabrics of different thicknesses and textures, ensuring feeding speed and accuracy. The folding mechanism uses a robotic arm and folding plate to fold the hem, precisely folding according to set widths and angles to meet diverse hem requirements. The sewing mechanism is the core component, equipped with a high-speed sewing machine. Stitch length, stitch length, and other parameters can be flexibly adjusted, ensuring stable sewing along the folded edge. The control system coordinates the work of each part by programming operating modes and parameters. The machine frame provides stable support for all components, ensuring machine stability during high-speed operation. It is widely used in industries such as garment manufacturing. In practical applications, the worm gear synchronous belt correction device typically requires the following technologies:

[0003] 1. Precision feeding technology: High-precision servo motors drive the feeding rollers, combined with photoelectric sensors to monitor the position and feeding speed of the fabric in real time;

[0004] 2. Intelligent folding technology: By installing angle and position sensors in the folding mechanism, the movement of the folding plate is precisely controlled;

[0005] 3. High-efficiency sewing technology: The sewing machine adopts a direct drive motor, which has a fast response speed and can achieve high-speed sewing. In addition, by optimizing the movement trajectory of the needle bar and the pressure control of the presser foot, the occurrence of skipped stitches and thread breaks is reduced.

[0006] 4. Fault diagnosis and remote monitoring technology: Multiple sensors are installed inside the machine to monitor parameters such as motor temperature, speed, and sewing tension.

[0007] Currently, existing worm gear synchronous belt correction devices have many important functions. In terms of improving production efficiency, their automated operation process reduces the time spent on manual folding and sewing of hems, enabling the rapid processing of large quantities of garment hems and increasing the overall production speed of garment manufacturing. In terms of quality assurance, precise feeding, folding, and sewing technologies ensure the dimensional accuracy, shape accuracy, and sewing quality of the hems, making the quality of garment products more stable and reliable. In terms of operational convenience, various parameters can be easily adjusted through the control system to adapt to the processing requirements of hems for different styles of garments, reducing the labor intensity and technical threshold for operators. In terms of production management optimization, fault diagnosis and remote monitoring technologies facilitate enterprises in managing and maintaining equipment, extending equipment lifespan, and improving the economic benefits of enterprises.

[0008] However, the above methods have a prominent hardware structural problem. The selvage correction mechanism usually uses a worm gear mechanism installed inside the feeding roller. The worm gear mechanism uses the teeth of the worm wheel that protrude from the surface of the feeding roller to drag the fabric and correct the selvage position. Because the teeth of this structure are exposed on the surface of the feeding roller, they can hook onto the fabric when the ring-shaped fabric is fitted, making it inconvenient to operate. Another type is a structure in which a worm gear drives an elastic O-ring transmission belt to drag the fabric. This structure has a high transmission ratio of the worm gear pair and a slow transmission belt speed, resulting in slow selvage correction speed and a small contact area with the fabric, causing wrinkles. This application proposes a solution to this problem, in which the main spindle motor and the correction motor rotate simultaneously, and the speed is adjustable to adapt to different fabrics. The correction device includes a main spindle assembly, a correction wheel assembly, and a secondary wheel assembly connected in sequence. Both the main spindle and the correction motor are stepper motors, which can be operated by a PLC operating system or a microcontroller system. The main and secondary wheels use bearings to rotate internally, and synchronous belts are used externally for correction, increasing the point of action and contact surface for correction.

Another approach is a worm gear driven by an elastic O-ring transmission belt to drag the fabric.

When the fabric deviates, the rotation of the correction motor is controlled to make the correction wheel assembly rotate. At the same time, the 128 teeth of the SM2 synchronous belt move.

[0026] This application embodiment provides a worm gear and worm synchronous belt correction device, which effectively solves the problem that the common fabric edge correction mechanism uses a worm gear mechanism installed inside the feeding roller. This mechanism uses the teeth of the worm gear protruding from the surface of the feeding roller to drag the fabric and correct the edge position. However, because the teeth are exposed on the surface of the feeding roller, they can hook onto the fabric when fitting a ring-shaped piece, making operation inconvenient. Another method is a worm gear and worm drive elastic O-ring transmission belt to drag the fabric. However, this method has a high transmission ratio and slow belt speed. This design addresses the technical issues of slow fabric correction speed and small contact area with the fabric, leading to wrinkles. The correction device comprises a main shaft assembly, correction wheel assemblies (each assembly including a driven wheel, belt idler pulley, and driving wheel), and auxiliary wheel assemblies. The main shaft assembly includes a hollow main shaft, a fixed base, etc., connected to a main shaft motor for auxiliary feeding. The correction wheel assembly includes a planetary gear carrier, several sets of correction wheels housed within the planetary gear carrier, several belt idler pulleys, and multiple synchronous belts driven by the correction wheel assembly, connected to the correction motor for fabric correction. The auxiliary wheel assemblies include bearing assemblies, a drive shaft, etc., used to connect the main shaft and correction wheels for rotation. When fabric correction is not required, the main shaft motor rotates, causing the hollow main shaft to rotate; in this case, the correction wheel assembly does not perform correction operation. When the fabric shifts, the rotation of the correction motor causes the correction wheel assembly to rotate, and simultaneously the synchronous belt moves. The correction wheel assembly and the synchronous belt move the fabric on the correction wheel assembly in the opposite direction to the shift direction, thus positioning the fabric correctly and completing the correction operation. This automatic correction device prevents fabric from snagging during application, making operation convenient. Furthermore, its low transmission ratio ensures sensitive correction. Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application effectively solves the problem that the selvage correction mechanism typically uses a worm gear mechanism inside the feeding roller. This mechanism uses the teeth of the worm wheel protruding from the surface of the feeding roller to drag the fabric and correct the selvage position. However, this structure, because the teeth are exposed on the surface of the feeding roller, can hook onto the fabric when fitting an annular piece, making operation inconvenient. Another approach is a structure where a worm gear drives an elastic O-ring transmission belt to drag the fabric. This structure, due to the high transmission ratio of the worm gear pair and the slow speed of the transmission belt, results in slow selvage correction speed and a small contact area with the fabric, causing wrinkles. The overall approach is as follows:
