It is engineered to provide uniform pressure, ensure strong adhesion, and enhance production efficiency through automation. This machine caters to manufacturers who require a reliable, precise, and easy-to-operate machine to reinforce and press soles during shoe assembly. With its double station design, it offers increased productivity and smooth workflow integration.

Features and Working Principle

Suitable for Reinforcing and Pressing All Kinds of Shoes

The TH-587-1 machine is versatile and robust, capable of reinforcing and pressing various types of footwear when the sole is bonded. Whether you are producing casual shoes, formal shoes, sports shoes, or boots, this machine is designed to handle diverse shoe styles and sole materials. It effectively improves the bonding strength between the sole and upper, ensuring the shoe structure remains intact during use.

Automated Control via Electrical and Pneumatic Components

This machine integrates electrical control systems with pneumatic components for fully automatic operation. The electrical control elements govern the pneumatic valves and cylinders, ensuring that the pressing process is consistent and repeatable.

• Air Source Pressure Regulating Valve: This valve allows the operator to adjust the working air pressure to the required level. Different shoes and sole materials may need different pressure settings, and this feature provides flexibility and precision.

• Time Relay for Pressure Holding: The time relay enables the machine to maintain pressure for a specific duration, which can be preset according to the adhesive and sole material requirements. This guarantees the glue cures properly, resulting in a strong, uniform bond.

User-Friendly Operation: Double Start Button Control

The machine requires the operator to place the shoes, pre-coated with adhesive, into the lower air box. To begin the pressing process, the operator simultaneously presses two start buttons. This safety feature ensures that the operator's hands are clear of the machine before activation, minimizing the risk of injury.

Pneumatic Pressing Using Inflatable Rubber Bags

Once activated, the air pressure automatically flows into the upper and lower rubber bags, inflating them to exert even pressure on the shoe. The inflation and deflation cycle presses the shoe firmly from both sides, ensuring:

• Uniform and tight bonding of the sole to the upper

• Enhanced adhesive layer performance

• Improved durability and wear resistance

• Reduced manual labor with quick operation cycles

The inflatable rubber bag design allows the machine to adapt to various shoe shapes and sizes, applying consistent pressure without damaging delicate materials.

Technical Specifications

• Voltage: 220V / 50Hz — Standard power supply compatible with most industrial settings worldwide.

• Air Pressure Range: 0.2 to 0.6 MPa — Adjustable air pressure ensures the machine can be fine-tuned for different shoe types and adhesive requirements.

• Machine Dimensions: 81 cm (Length) × 85 cm (Width) × 110 cm (Height) — Compact footprint suitable for diverse factory layouts.

• Package Dimensions: 90 cm (Length) × 95 cm (Width) × 133 cm (Height) — Dimensions for shipping and storage.

• Net Weight / Gross Weight: 265 kg / 290 kg — Sturdy construction using high-quality materials ensures durability and stability during operation.

Benefits of the TH-587-1 Machine

Enhanced Bonding Quality

The pneumatic pressing system ensures that the sole and shoe upper are bonded under uniform pressure, eliminating common defects like air bubbles, weak adhesion spots, and wrinkles in the sole. This uniformity significantly improves the shoe’s structural integrity and longevity.

Increased Production Efficiency

With its double station design, the machine allows for alternating operations: while one shoe is being pressed at one station, the operator can load or unload the other station. This continuous workflow increases output and minimizes downtime.

Reduced Labor Intensity

Automation of the pressing process reduces manual effort, decreasing operator fatigue and minimizing errors caused by inconsistent pressure application. This leads to better product quality and higher workforce efficiency.

Safety Features

The dual start-button control and pneumatic inflation system ensure that the machine operates only when it is safe to do so, reducing the risk of operator injury.

Flexibility and Adaptability

The adjustable air pressure and time relay settings allow the machine to be tailored to different materials and shoe constructions, accommodating evolving production needs without requiring extensive mechanical modifications.

Applications

The TH-587-1 machine is well-suited for:

• Footwear manufacturing companies specializing in bonded sole construction

• Factories producing diverse shoe types, including sports, casual, formal, and work boots

• OEM and ODM manufacturers seeking consistent quality and efficiency in sole-attaching processes

• Repair shops or small-scale producers requiring reliable pressing machines with automatic control

Operational Guidelines

Preparation

Before starting the operation, ensure the machine is connected to a stable power supply (220V/50Hz) and an air compressor capable of supplying air at pressures between 0.2 and 0.6 MPa.Adjust the air pressure regulating valve and time relay according to the adhesive manufacturer's recommendations and the specific sole material.

Loading the Shoes

Place the shoes, with the sole already coated in adhesive, into the lower air box of the machine’s pressing station. Make sure the shoe is properly positioned to ensure uniform pressure application.

Starting the Pressing Process

Press both start buttons simultaneously to initiate the pressing cycle. This safety mechanism ensures both of the operator's hands are clear. Once activated, air will inflate the upper and lower rubber bags, pressing the sole and upper together. The machine will maintain pressure for the preset duration, ensuring adhesive curing.

Unloading and Repeating

After the cycle ends, the air is exhausted, and the rubber bags deflate, releasing the shoe. Remove the pressed shoe and load the next pair to maintain workflow.

Maintenance Tips

Regularly inspect pneumatic hoses and rubber bags for wear or leaks. Keep electrical components clean and dry . Check and calibrate air pressure and timing controls periodically to maintain optimal performance. Lubricate moving parts as recommended by the manufacturer.
