TH-141L Double Wheel Dyeing Machine

The TH-141L Double Wheel Dyeing Machine is a precision-engineered tool designed for the detailed edge oiling of small leather goods, accessories, and specialized components. By utilizing a dual-roller system, this Dyeing Machine offers superior control over fluid thickness, making it a preferred choice for items with complex curved edges and small corners that require a refined finish.

In the professional production of high-end leather accessories, achieving a consistent edge coat on miniature parts is a significant technical challenge. The Double Wheel Dyeing Machine addresses this by providing a stable, low-profile platform that allows operators to guide workpieces with high accuracy. This equipment is particularly effective for finishing watch straps, jewelry wristbands, and zipper tails, where the quality of the edge oiling directly impacts the perceived value of the final product.

Precision Engineering of the Dual-Roller System

The fundamental advantage of the TH-141L lies in its mechanical configuration. Unlike standard single-wheel units, this Double Wheel Dyeing Machine employs two synchronized rollers to manage the application of edge paint. This design serves as a built-in regulation system for the oiling process.

The first wheel, partially submerged in the reservoir, acts as the pick-up roller. It carries the oil to the second wheel, which then transfers the paint onto the material. This indirect transfer method ensures that the application wheel of the Dyeing Machine is never over-saturated. By filtering the amount of oil passed between the wheels, the machine prevents common issues such as "beading" or overflow on the surface of the leather. For manufacturers working with delicate substrates or light-colored fabrics, this level of fluid management is an essential requirement for maintaining high yield rates.

Technical Parameters and Design Optimization

The TH-141L is designed with a focus on portability and energy efficiency, making it suitable for modular production lines or artisan workshops where bench space is limited.

The 2.2kg weight of the Double Wheel Dyeing Machine allows it to be easily repositioned within a facility to accommodate changing production needs. Furthermore, the 90mm height ensures that the operator's hands remain close to the workbench, which improves stability when handling small leather accessories. The 25W motor is calibrated to provide consistent torque at steady speeds, ensuring the rotating wheels do not stutter when they come into contact with the material.

Industrial Applications and Workflow Integration

This equipment is versatile enough to handle a wide range of materials beyond traditional leather. In modern garment and bag manufacturing, the Double Wheel Dyeing Machine is used to seal and color the edges of various substrates to improve both durability and aesthetics.

1. Watch Straps and Wristbands: The dual-wheel setup allows for a very fine application of paint, which is necessary for the tapered ends and narrow profiles of luxury watch bands.
2. Zipper Tails and Pullers: These small components often feature tight radii and small corners. The Dyeing Machine can navigate these shapes without clogging the zipper mechanism or leaving excess residue.
3. Leather Accessories: Items such as key fobs, luggage tags, and decorative charms benefit from the uniform coating provided by the dual-wheel system, ensuring a professional look across every unit in a batch.

By integrating the Double Wheel Dyeing Machine into the finishing department, factories can replace inconsistent manual painting with a standardized mechanical process. This leads to better uniformity in the "Bags And Leather Series" and reduces the time spent on quality control inspections.

Maintenance and Operational Longevity

To ensure the Dyeing Machine maintains its precision over years of use, a disciplined maintenance routine is necessary. Because edge oils are formulated to dry quickly and adhere strongly, any residue left on the mechanical parts can interfere with the fluid transfer.

The wheels of the Double Wheel Dyeing Machine should be removed and cleaned thoroughly after every shift. If oil is allowed to dry between the two rollers, it can create an uneven surface that causes streaks on the leather edge. Similarly, the reservoir must be emptied and rinsed to prevent the buildup of sediment that could be picked up by the primary roller. Regular lubrication of the internal drive shaft will keep the 25W motor running smoothly and quietly.
