Description

Technical Field

[0001] This utility model relates to the field of processing technology, and in particular to a self-feeding mattress rewinding device. Background Technology

[0002] Mattress roll-up technology is a key innovative process developed to address the problems of traditional mattresses being bulky and incurring high warehousing and transportation costs. This technology significantly reduces the size of the mattress by forcefully compressing it, allowing it to be packaged and transported in a rolled-up form. This significantly reduces logistics difficulties and costs, and is particularly well-suited to the needs of modern e-commerce direct sales models.

[0003] Currently, the mainstream rolling and packaging processes are as follows:

[0004] ①Lamination: A special packaging film is pre-covered on the top and bottom surfaces of the mattress, with the edges of the film extending to the outside of the mattress;

[0005] ②Thinning: Thinning the mattress;

[0006] ③ Sealing: The edges of the upper and lower packaging films are heat-sealed, so that the upper and lower packaging films form a sealed "film bag" that completely encapsulates the compressed mattress. Moreover, after the mattress is released, the mattress's own elasticity is not enough to tear the sealed edge of the packaging film, thus keeping the mattress in a compressed state.

[0007] ④ Rolling: Roll up the compressed mattress to turn the original block mattress into a roll.

[0008] After receiving the package, consumers only need to unfold the rolled-up mattress, flatten it, and then tear open the packaging film. The mattress will then return to its original shape thanks to its own elasticity.

[0009] Despite significant advancements in compression and securing technologies, achieving a high degree of automation, existing wrapping equipment suffers from a common drawback at the end of the process: after wrapping operations (including lamination, thinning, edge sealing, and winding) are completed, the rolled-up mattress roll remains on the equipment's mattress reel. The subsequent unloading process—removing the mattress roll from the reel—still relies entirely on manual operation.

[0010] This manual material unloading method has become a key bottleneck restricting further improvements in production efficiency. Therefore, it is necessary to improve existing rolling and packaging equipment to solve the problem of its inability to achieve mechanized unloading of mattress rolling and packaging.

[0011] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0094] In summary, the self-feeding mattress winding device provided in this embodiment has the following advantages:

[0095] ① By setting a mattress receiving groove 2011 and a hot pressing strip 2012 on the edge sealing plate 201, the pressing and edge sealing processes are completed simultaneously, ensuring the quality of edge sealing and simplifying the structure.

[0096] ②The movable clamping plate 3041 with inclined surface 3041a in the clamping assembly 304 can be easily inserted into the bottom of the mattress and clamp the starting end, which improves the feeding efficiency and reliability.
