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

The machine features optional pincers with a quick removal design, facilitating easy replacement and maintenance. This design minimizes downtime during pincer changes and ensures consistent, lasting quality.

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.

Manual Control of Pincer Groups

After the pincers hold the vamp, operators can manually control the release and clamp of the pincers within the same group. This feature allows for fine-tuning during the finishing process, ensuring optimal fit and finish.

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-739MA 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

• Automatic Glue Feeding Mechanism: Automates the glue application process, ensuring precise gluing positions, reducing labor requirements, and increasing production efficiency.

Electric Control Pincer Plate

The pincer plate features electric control for left and right lateral opening and closing, facilitating convenient pincer replacement and maintenance.
