In the dynamic world of footwear manufacturing, precision, efficiency, and adaptability are paramount. The TH-747A 9 Pincers Computer Memory Control Automatic Toe Lasting Machine stands as a testament to advanced engineering, designed to meet the rigorous demands of modern shoe production. With its state-of-the-art features and robust construction, the TH-747A ensures consistent quality, reduced downtime, and enhanced productivity.

Hydraulic Operation System

The TH-747A utilizes a fully hydraulic operation system, ensuring stable and reliable machine performance during the lasting process. This system provides consistent pressure and movement, resulting in uniform quality across all produced footwear.

PLC Controller with Touchscreen Interface

Equipped with a Programmable Logic Controller (PLC) and a user-friendly touchscreen interface, the machine offers intuitive operation. Parameters such as stroke and time can be set by entering numerical values, and a key switch prevents unauthorized changes, enhancing operational security.

Memory Storage for Shoe Patterns

The PLC controller can store up to 100 groups of shoe pattern parameter data and pincer locations. This feature allows for quick retrieval and setup, significantly reducing changeover time between different shoe models and increasing overall production efficiency.

Error Diagnostic Function

An integrated error diagnostic function enables rapid identification and troubleshooting of issues, minimizing downtime and maintaining continuous production flow.

Quick-Removal Pincers with Double Track Mechanism

The machine features pincers with a quick removal design, facilitating easy replacement and maintenance. These pincers are fixed in a patented double-track pincer disc mechanism with a second pincer displacement structure, allowing for precise adjustments and enhanced flexibility in handling various shoe designs.

Adjustable Middle and Fifth Pincers

• Middle Pincer Deflection: The middle pincer can deflect 15 degrees to the left and right, accommodating special toe cap shapes and various shoe model arrangements.

• Fifth Pincer Rotation: The fifth pincer can be set for automatic rotation, enhancing the lasting effect on the inner waist of the shoe.

Independent Pincer Control

Each pincer can be set to automatic pull-down stroke independently or manually operated lifting, allowing the tension of the vamp to be balanced to correct the optimal position of the lasting. After the pincer holds the vamp, operators can manually control the release and clamp of the pincers within the same group.

Two-Stage Inner Support Table Rise

The inner support table's height is adjustable from the machine's exterior and displayed with an indicator ruler. It can be set for a two-stage rise action, working in conjunction with the heel top seat action to prevent the latter from sliding, thereby ensuring precise positioning during lasting.

Adjustable Inner Support Platform

The front and back positions of the inner support platform can be adjusted up to 16mm using a handwheel located at the front of the machine. This adjustability allows for the accommodation of various shoe sizes and designs, enhancing the machine's versatility.

Two-Stage Press Head Mechanism

The press head mechanism adopts an adjustable two-stage pressure system. It can be set to either constant pressure control or positioning control during the first pressure stage, providing flexibility to suit different materials and shoe designs.

Optional Auxiliary Mechanisms

Depending on production needs, the TH-747A can be equipped with optional auxiliary mechanisms, including:

• Auxiliary Sweep Knife Mechanism: Enhances the lasting process by ensuring smooth and uniform material application.

• Auxiliary Holding Mechanism: Provides additional support during the lasting process, improving accuracy and consistency.

Three-Layer Pincer Disc Structure

The newest design of the three-layer pincer disc structure allows for rotating the dot to move left and right, matching the middle pincer with quick separation. This design enables rapid arrangement changes of pincers for different shoe styles, enhancing the machine's adaptability.

Operational Advantages

• High Precision: The digitized adjustments ensure consistent and precise toe lasting, reducing material wastage and rework.

• Enhanced Productivity: With a capacity of 2000 pairs per 8-hour shift, the TH-747A meets high-volume production demands.

• Versatility: The ability to store multiple shoe models and adjust to various materials makes it suitable for diverse production lines.

• Reduced Downtime: Quick adjustments and memory storage minimize setup times between different production runs.

Applications

The TH-747A is ideal for manufacturers producing:

• Casual Footwear: Ensuring comfort and consistency in design.

• Formal Shoes: Maintaining the sleek and precise appearance required.

• Sports Shoes: Handling diverse materials and designs with ease.

• Children's Footwear: Accommodating smaller sizes with high precision.

The TH-747A 9 Pincers Computer Memory Control Automatic Toe Lasting Machine is a fusion of innovation and practicality. Its advanced features, combined with user-friendly operations, make it an indispensable asset for footwear manufacturers aiming for excellence in quality and efficiency.
