Treadmill belt and running belt joint heat welding

As people's living standards improve, more and more people begin to pay attention to their health. As a convenient fitness equipment, treadmills have become an indispensable part of many people's daily lives. As one of the important components of a treadmill, the quality of the treadmill belt directly affects the performance and service life of the treadmill. This article will give a detailed introduction to the treadmill belt, and focus on the joint heat welding process.

1. Types and characteristics of treadmill belts

1. Nylon belt: Nylon belt is a commonly used treadmill belt material with high strength and wear resistance and a long service life. At the same time, the air permeability and moisture discharge of nylon belts are good, which can effectively reduce the heat and moisture generated during exercise.

2. Polyester belt: Polyester belt is a high-strength and high-wear-resistant treadmill belt material, suitable for high-speed and heavy-load use environments. However, the air permeability and moisture discharge of polyester belts are relatively poor, which can easily lead to excessive heat and moisture during exercise.

3. PVC belt: PVC belt has good flexibility and tensile strength.

4. Rubber belt: Rubber belt is a treadmill belt material with high elasticity, which can effectively absorb the impact force generated during exercise and protect the safety of the treadmill and the user. However, the price of rubber belt is relatively high, and its oil resistance, acid and alkali corrosion resistance are poor.

2. Selection and installation of treadmill belt

1. Selection: When choosing a treadmill belt, you should choose the appropriate belt material and specifications according to the type of treadmill, the use environment and personal needs. Generally speaking, high-speed and heavy-load treadmills should use high-strength and high-wear-resistant running belts; while low-speed and light-load treadmills can choose running belts with better softness and tensile resistance.

2. Installation: The installation of the treadmill belt requires professional operation to ensure that the belt is installed accurately and the tension is moderate. During the installation process, the following points should be noted:

Ensure that the contact surface between the belt and the treadmill gear is clean and free of oil;
When adjusting the belt tension, the belt should be slightly tightened;
Apply an appropriate amount of hot melt adhesive to the belt interface, and then heat the two belts together through the heat sealer to ensure that the interface is firm and reliable.

3. High-frequency heat-sealing welding process for running belt joints

The high-frequency heat-sealing welding process for joints is a common way to connect treadmill belts, which has the characteristics of firm connection and strong durability. The following is a detailed introduction to the joint heat-sealing welding process:

Preparation: Before performing joint heat-sealing welding, the treadmill belt interface should be cleaned to remove impurities such as oil and dust; at the same time, turn on the high-frequency welding machine for preheating and preparation.
Heating: Raise the temperature of the high-frequency machine to an appropriate range.
Alignment: Align the treadmill belt interfaces to be welded at both ends to ensure that the interface parts are on the same plane. During the alignment process, try to avoid stretching or compressing the belt.
Heat-sealing: Lower the head of the high-frequency machine and press the joint. During the compression process, a certain pressure time should be maintained so that both ends of the running belt joint are fused together.
Curing: Wait for a period of time (generally 10-30 seconds) to form a firm structural connection during the cooling process.
Inspection: After heat sealing, you can gently pull the interface by hand to check whether the connection is firm. If you find that the connection is not firm or there are problems such as bubbles, you should adjust and deal with it in time.

IV. Summary

As an important part of the treadmill, the quality of the treadmill belt directly affects the performance and service life of the treadmill. Therefore, when purchasing and using the treadmill belt, you should pay attention to reasonable selection, correct installation, and firm heat welding of the joints to ensure the safe and stable operation of the treadmill. At the same time, regular inspection and maintenance of the treadmill belt is also an important measure to extend its service life.
