Description

Technical Field

[0001] The utility model relates to the technical field of mattress processing, in particular to a spring threading device for a mattress frame. Background Art

[0002] Spring mattresses are commonly known as "Simmons" in China. They are commonly used modern mattresses with good performance. Their core is composed of springs. The mattress has the advantages of good elasticity, good support, strong air permeability, and durability. When producing spring mattresses, the springs inside the mattress need to be connected in series with serpentine springs to form a rectangle. The traditional spring stringing process is manual. With the development of technology, semi-automatic spring stringing machines and automatic spring stringing machines have been introduced on the market. The more advanced one is the automatic spring stringing machine.

[0003] The Chinese patent with the authorization announcement number CN217959457U discloses a spring threading device for a mattress frame, including a base, a wire feeding mechanism and a feeding mechanism.

The spring threading device for a mattress frame pushes the spring into the spring threading machine through the feeding mechanism, thereby improving the production efficiency. At the same time, the spring can be placed in the spring threading machine just by pressing the pressing plate, thereby ensuring the practicality of the device. In combination with the existing spring threading machine equipment, the production efficiency of the device is improved. Manual labor only needs to place the spring in the placement slot, thereby reducing the manual labor and improving the work efficiency.
