Description

Technical Field

[0001] The utility model relates to the technical field of mattress machinery, in particular to a surface cloth cutting mechanism used in the production of bed nets. Background Art

[0002] Mattress is a commonly used furniture, generally composed of bed net and outer packaging.

[0003] The existing bed net production is generally made by welding or gluing multiple spring strips. When producing the bed net, a piece of cover cloth needs to be fixed on the top and / or bottom of the bed net. The existing production technology generally glues a continuous cover cloth on the top and / or bottom of the bed net during the welding / gluing process of the bed net, and the size of the cover cloth is larger than the size of the bed net, so the cover cloth needs to be cut after the production is completed to separate the finished products.

[0004] The existing cutting device directly sets a cutter that can cyclically move. When the face cloth between two bed nets passes the cutter, the cutter cuts through the face cloth between the two bed nets, thus completing the face cloth cutting process. However, in actual production, since the size of the face cloth is much larger than the size of the bed net, at this time, for some high-height bed nets, the two sides of the face cloth at the top of the bed net will naturally sag, and when tensioned by the tensioning roller, it is impossible to ensure that the two sides of the face cloth are tensioned. At this time, it is easy to cause the cutter to align with the two sides of the face cloth, resulting in the situation that the two sides are not cut off during cutting. Utility Model Content
