[0002] A mattress is an item placed between a human body and a bed to ensure that consumers obtain healthy and comfortable sleep. There are various mattress materials, and mattresses made of different materials can bring different sleep effects. With the continuous progress of material civilization and technology, the types of mattresses used by modern people are gradually tending towards diversification, mainly including: spring mattresses, palm mattresses, latex mattresses, water mattresses, inclined headrest spinal care mattresses, air mattresses, magnetic mattresses, etc. Among these mattresses, spring mattresses account for a relatively large proportion.

[0003] However, during mattress production, it is necessary to pack the mattress by putting a bag cover into the mattress and then sewing the bag cover. However, due to the different specifications of mattresses, it is easy to have deviations during manual packing, and with long-term work, it is easy to lead to low work efficiency and there are also certain risks.
