TH-141M Single Wheel Dyeing Machine

The TH-141M Single Wheel Dyeing Machine is a compact, benchtop unit designed for the precision oiling of small-scale leather components and

In industrial leather production, the challenge of finishing small corners often involves managing the fluid thickness on a narrow applicator. The Dyeing Machine features a 150mm wide footprint, allowing it to fit into modular assembly stations without obstructing other mechanical operations. By employing a single-roller design, the equipment reduces the complexity of the fluid transfer path, which is essential for maintaining consistent

Mechanical Design and Edge Processing

The structural layout of the TH-141M Single Wheel Dyeing Machine is centered on direct-drive rotation. The motor provides steady torque to a brass or stainless steel wheel that sits partially submerged in an integrated oil reservoir. This direct contact ensures that the wheel picks up a continuous film of edge paint, which is then transferred to the leather substrate as it is guided along the rotating surface.

The narrow profile of the wheel on this Dyeing Machine is a technical requirement for processing zipper tails and small leather pulls. When an operator guides a curved edge against the wheel, the single contact point allows for a smooth pivot. This prevents the "edge-clumping" effect often seen when trying to use wide-roller machines on sharp internal arcs. The mechanical simplicity of the single shaft also means there is less friction and heat buildup, which preserves the chemical integrity of temperature-sensitive edge oils.

Technical Parameters and Benchtop Specifications

The TH-141M is engineered for energy efficiency and portability, utilizing a standard 220V power supply that is compatible with most industrial and workshop electrical grids.

The 1.1kg chassisSingle Wheel Dyeing Machine maintains enough structural mass to prevent "walking" on the workbench while the 25W motor is engaged. The 110mm height is ergonomically matched to standard seated workstations, allowing operators to maintain a natural wrist angle when feeding materials like tapered wristbands or circular leather patches.

Application Logic for Small Components

For a Single Wheel Dyeing Machine, the operational logic is based on the speed of the wheel relative to the manual feed rate of the operator. Achieving a professional finish on a 90-degree corner or a 5mm radius requires the machine to maintain a constant RPM without stalling under the pressure of the leather piece.

1. Watch Straps and Wristbands: The single wheel allows the operator to coat the narrow edges and buckle holes with high precision. The narrow applicator prevents oil from seeping into the stitching channels.
2. Zipper Tails and Pullers: These parts require a 360-degree finish. The Dyeing Machine allows for a continuous rotation of the part against the wheel, ensuring the rounded end is sealed without leaving a visible "start-stop" mark.
3. Circular Leather Edges: The 150mm length of the machine provides enough clearance for the operator to rotate circular discs or curved handbag ornaments without the workpiece hitting the motor housing.

By utilizing this specialized Single Wheel Dyeing Machine, factories can reduce the reject rate associated with manual oiling. The mechanical application ensures that the depth of the oil penetration into the leather fibers is uniform, which is necessary for achieving long-term adhesion and preventing the edge paint from peeling in humid environments.

Maintenance and Component Care

The longevity of the Dyeing Machine is directly tied to the cleanliness of the applicator wheel and the internal drive assembly. Because edge oil is a fast-drying polymer, even a small amount of dried residue can cause the wheel to become unbalanced or create physical striations in the finish.

• Wheel Cleaning: The applicator wheel of the Single Wheel Dyeing Machine should be detached at the end of every shift. Soaking the wheel in a compatible solvent removes hardened paint from the microscopic grooves of the metal, ensuring the next batch of oil adheres correctly.
• Reservoir Management: The small oil tank must be emptied and wiped down to prevent sediment from settling at the bottom. Sediment buildup can increase the load on the 25W motor and lead to premature wear of the drive gears.
• Drive Shaft Lubrication: A drop of industrial lubricant on the rotating shaft of the Dyeing Machine every 50 hours of operation will maintain the quiet, low-vibration performance required for precision work.

Guangdong Tenghong Machinery Technology Co., Ltd. has manufactured these units since 2000, utilizing a 15,000㎡ production base to ensure all mechanical tolerances are met. The TH-141M Single Wheel Dyeing Machine is a result of years of field testing in high-volume footwear and bag factories where durability and ease of cleaning are the primary concerns.

For B2B buyers, the integration of this Dyeing Machine into the final assembly line represents a move toward standardized detailing. Our hardware is currently exported to 26 countries, reflecting the global demand for reliable, small-scale leather finishing solutions. The TH-141M provides the specific mechanical torque and applicator geometry needed to handle the most difficult leather shapes in any modern production environment.

Choosing the TH-141M Single Wheel Dyeing Machine ensures that your facility can handle intricate detailing with the same level of consistency as straight-edge production. With its 1.1kg portable design and efficient 25W motor, it remains a functional staple in the toolset of any professional leathergoods manufacturer.
