Insole gluing machine

Types of insole gluing machines

An insole gluing machine is a specialized piece of equipment used to attach insoles to the inner bottom part of shoes. It performs the same function as hand pasting but with more efficiency and speed. There are various ways to classify the insole gluing machines. Based on the method of application, they can broadly be divided into spray applicators, roll applicators, and brush applicators.

• Spray applicator:

  The spray applicator is built with a sprayer that applies adhesive evenly on the insole or the shoe last. It is often combined with a hot air blow device that helps the adhesive activate and dry properly. This machine is advantageous because it minimizes the amount of adhesive required to achieve a bond while also reducing the time spent on the gluing process. The uniform application of adhesive leads to consistent and high-quality results.

• Roll applicator:

  This machine applies adhesive to the insole using a rotating roller. The roller is designed to distribute adhesive evenly across the insole surface. This method of application reduces the amount of adhesive needed and ensures uniform coverage. In addition to reducing adhesive waste, the roll applicator speeds up the gluing process considerably, allowing for higher productivity in shoe-making operations.

• Brush applicator:

  In some cases, adhesive is applied with a brush to a designated area of the shoe or insole. The adhesive is then allowed to dry before the two parts are brought together. The brush applicator offers the flexibility to control the amount of glue applied, but it is not as efficient as other types of applications.

Insole gluing machines can also be classified based on their automation. There are low-tech machines that are manually operated and semi-automated machines that are partially automated but require manual intervention. Other types include the manual insole gluing machine and the automatic insole gluing machine. The manual machine requires a manual adjustment of the heating plate while the automatic has a programmable control system with automatic heating and cooling function.

Specifications and Maintenance

Some remarkable characteristics and requirements for specific types of insole-gelling machines are as follows:

• Production Capacity: Different machines have different production rates, often documented in pairs of shoes each hour. For instance, some might make 800-1000 pairs of shoes in one hour. This means that if a business runs a machine for 10 hours, it could produce between 8,000 and 10,000 pairs of shoes in a day. Knowing the production rate helps businesses plan how many machines they need to meet their production goals.
• Insole Types and Adhesives Compatibility: Different machines are built to work with particular kinds of insoles (like foam, gel, or custom) and specific shoe parts. An insole gluing machine should effectively apply adhesive to multiple insole materials, ensuring a strong bond. Also, the adhesive used in the gluing process is essential. An insole gluing machine must work effectively with different adhesives, whether water-based, solvent-based, hot melt, or spray adhesive. The machine must apply the adhesive uniformly and consistently for optimal bonding between the insole and the shoe.
• Precision and Speed: Precision insole gluing machines ensure accurate adhesive placement, avoiding excess glue and ensuring a perfect fit. On the other hand, Speed refers to how fast the machine works, often measured in how many parts it handles in a set time. Balancing precision and speed is essential for efficient insole attachment without compromising quality control.
• Adjustability and Automation: Adjustability and automation in an insole glue machine enhances agility and efficiency in the insole attachment process. Automation reduces manual intervention, accelerating production while maintaining consistent adhesive application. Adjustable settings allow the machine to accommodate various insole shapes and sizes, ensuring a perfect fit for different shoe designs.

For the machine to serve its purpose for a long time, maintenance is crucial. For an insole gluing machine, several maintenance methods are required for the machine to function properly. Regular cleaning is very important. It helps to ensure that the application parts and nozzles are always clean. Notably, during routine cleaning, strong corrosive chemicals shouldn't be used to avoid damaging the machine.

Secondly, lubrication of moving parts is essential. Lubricating moving parts helps to avoid friction and wear. It extends the lifespan of the machine. Operators are advised to use high-quality lubricant products only.

Regular inspection and replacement of damaged parts is another maintenance technique. Performing regular inspections helps operators to note and replace quickly any damaged or worn-out parts. This helps the machine maintain optimal performance.

Finally, periodic calibration is required for the machine to function optimally. It helps to ensure that adhesive application pressure and quantity are correct. Also, operators can adjust the machine according to the different sizes and types of insoles required.

Usage scenarios of insole gluing machines

Insole gluing machines apply hotmelt adhesives or other types of adhesives to attach shoe insoles to the interiors of shoes. These machines play a crucial role in ensuring that insoles are securely bonded to the shoe interior, thereby providing comfort, support, and durability to the footwear. The use of insole gluing machines is widespread.

• Industrial shoe manufacturing: Large-scale shoe manufacturers typically use insole gluing machines to mass-produce various types of athletic, casual, and specialty footwear. These machines are often used in high-production facilities to efficiently attach insoles to shoes. The precision and speed of insole gluing machines make them suitable for use in automated or semi-automated insole-attaching lines, where multiple machines may be used simultaneously to meet high production volumes.
• Small-scale shoe manufacturing: Small-scale shoe manufacturers, such as those producing boutique or specialty footwear, may also utilize insole gluing machines in their production processes. While the production volumes may be lower compared to large-scale manufacturers, the efficiency and consistency offered by insole gluing machines are valuable even in smaller production settings. These machines help small-scale manufacturers maintain quality, streamline their operations, and meet the demands of discerning customers who expect well-constructed shoes with properly attached insoles.
• Shoe repair services: An insole gluing machine can also be used in shoe repair services to reattach insoles to shoes that have become loose or damaged. Shoe repair services typically provide restoration, mending, and maintenance services to help individuals extend the life of their footwear. With time and usage, the insoles of shoes can become detached or worn out, requiring replacement or reattachment. An insole gluing machine can be a valuable tool for shoe repair technicians, as it allows for precise and even adhesive application when reattaching insoles to shoes.

How to choose an insole gluing machine

• Quality of work:

  When it comes to insole gluing machines, the standard of work they do is crucial.

• Compatibility with production line:

  Indeed, it is vital to ensure that the machine used to glue insoles fits well with the rest of the tools and machines used to make shoes. Because of this, it operates smoothly and increases productivity effortlessly. The shoe production process becomes more manageable and efficient when all the equipment collaborates effectively.

• Budget:

  When buying an insole-gluing machine, people need to consider how much money they have to spend carefully. It's essential to have a spending plan that includes the amount set aside for purchasing the machine. This budget will help determine what kind of machines can be bought and which are within the reasonable spending range. Investigating different machines and knowing their prices can significantly impact deciding which one to choose that fits the budget the best.
