Description

Technical Field

[0001] The utility model belongs to the technical field of inner tube processing, in particular to an automatic inner tube nozzle pressing machine. Background Art

[0002] An inner tube, commonly known as a tire, is a donut-shaped elastic tube with a tire valve that maintains internal tire pressure. The valve is used to inflate and maintain a constant air pressure within the inner tube. Inner tubes should exhibit excellent airtightness, heat resistance, elasticity, aging resistance, and minimal permanent deformation. They are typically made of butyl rubber. Inner tubes serve as air-bearing containers for inflation and vibration reduction, serving as auxiliary pressure-bearing containers within the tire cavities of trucks, motorcycles, bicycles, and rickshaws.

[0003] Tire valves, also known as valve nozzles, are one-way valves used to inflate and discharge gas or liquid in tires and can maintain and detect internal pressure. During the inner tube processing process, the valve nozzles are pressed into the inner tube. However, when pressing the valve nozzles, the inner tube needs to be perforated in advance, and then the valve nozzles need to be manually placed in the perforated position before the pressing process can be performed. Although this method can press the valve nozzles, it is difficult to quickly open and press the valve nozzles and inner tube, which reduces the efficiency of the equipment. Utility Model Content
