Description

Technical Field

[0001] This utility model relates to the field of armband sewing technology, and in particular to an armband wrapping sewing mechanism. Background Technology

[0002] Armbands, as common water sports aids, fitness equipment accessories, and children's toys, are widely used in daily life and various industries. With rising living standards and changing consumption habits, the demand for armbands is becoming increasingly diversified. In terms of materials, there are different types, including rubber, silicone, and plastic; in terms of function, in addition to basic buoyancy assistance, there are products with special functions such as massage and illumination; and in terms of design, they come in a wide variety of colors and shapes. Armbands with different aperture sizes meet the needs of people of different ages and body types; for example, children's armbands have relatively smaller apertures, while adult armbands have larger apertures to ensure comfort and a good fit. This diversified product demand prompts manufacturers to continuously seek more efficient and flexible production methods to meet market needs.

[0003] Most existing equipment's clamping and support structures lack versatility and are difficult to adapt to the fixing requirements of arm rings with different aperture diameters. Some equipment's clamping devices are designed for specific aperture diameters, and cannot effectively clamp and support arm rings with large aperture differences. This causes the arm rings to easily shift or wobble during sewing, affecting sewing accuracy and increasing the defect rate. Therefore, an arm ring wrapping sewing mechanism is proposed.

[0014] (III) Beneficial Effects

[0015] This utility model provides an arm loop wrapping sewing mechanism, which has the following beneficial effects:

[0016] 1. This arm ring surrounding sewing mechanism, through the setting of the clamping mechanism, when in use, the arm ring is placed on the surface of four clamping heads, and then the servo motor on one side of the clamping head is started. The servo motor drives the end rotating disk to rotate, so that the four connecting rods on the surface of the rotating disk pull the end limiting plate to move during the rotation, thereby realizing the relative movement of the clamping head connected to the top of the limiting plate.

[0017] 2. This arm-shaped sewing mechanism, through the setting of the lifting mechanism, allows for height adjustment of the worktable at the bottom base by activating the drive motor according to the different heights of the operators. The drive motor drives the end screws to rotate, which in turn causes the two threaded blocks connected by the threads on the surface of the screws to move relative to each other. The two support rods at the top of the threaded blocks rotate accordingly, thereby achieving the effect of adjusting the height of the worktable at the top of the support rods. This makes it convenient for operators of different heights to use, providing convenience for operators. Attached Figure Description
