Description

Technical Field

[0001] The present invention relates to the technical field of double-layer material belt conveying, and in particular to a double-layer material belt non-stop material changing device and a production process thereof. Background Art

[0002] In the production process of material strips such as PVC film, low-viscosity film, hydrocolloid, and non-woven fabrics, when the material strip on the unwinding shaft is almost used up, the traditional material changing device mostly uses a material receiving table. The material receiving table first aligns the new material and the old material and then cuts them, and then uses tape to bond them at the cut position to complete the material change. The traditional material changing device is only suitable for the material change of single-layer material strips. If the material strip is double-layered, the traditional material changing device does not have a space and mechanism for pasting the lower layer of tape. The traditional material changing device can only bond the upper layer of material strips, but not the lower layer of material strips. Therefore, the traditional material changing device has certain limitations for the material change of double-layer material strips.
