Description

Technical Field

[0001] This utility model belongs to the field of mattress processing technology and relates to a four-way centering alignment device for mattresses. Background Technology

[0002] A mattress is an item placed between the human body and a bed to ensure consumers get healthy and comfortable sleep. Mattresses are made of a variety of materials, and mattresses made of different materials can provide different sleep effects.

[0003] Chinese Patent Publication No. CN217295061U discloses a mattress centering machine, comprising: a support frame; two slide rails mounted on the support frame; a first push rod assembly and a second push rod assembly, both slidably mounted on the two slide rails; a drive mechanism mounted on the support frame, used to synchronously drive the first push rod assembly and the second push rod assembly to move closer to each other along the slide rails to center and correct the mattress located between the first push rod assembly and the second push rod assembly, or to move further apart along the slide rails. The drive mechanism includes a drive motor, a transmission shaft driven to rotate by the drive motor, a first sprocket fixedly mounted on the end of the transmission shaft, a second sprocket fixedly mounted on the support frame, and a chain mounted between the first sprocket and the second sprocket. Each end of the transmission shaft has a first sprocket fixed to it, and each first sprocket is mounted with a chain. There are two first connectors and two second connectors, each fixed to one of the two chains.

[0004] The patent provides a mattress centering machine that uses a chain drive. This structure is noisy, and after long-term use, the teeth of the sprocket will wear due to friction, resulting in changes in tooth shape and uneven tooth pitch. When the wear reaches a certain level, the fit between the chain and the sprocket deteriorates, and the chain is prone to falling off the sprocket. The fallen chain will cause entanglement, affecting production efficiency. Utility Model Content
