Description

Technical Field

[0001] The utility model relates to the technical field of feeding materials for a blister machine, in particular to a dust-proof feeding structure for a blister machine. Background Art

[0002] The blister machine, also known as the thermoplastic forming machine, is a machine that blister-forms heated and plasticized thermoplastic plastic coils such as PVC, PE, PP, PET, HIPS, etc. into various shapes of advanced packaging decoration boxes, frames, and other products. Using the vacuum suction force generated by the vacuum pump, the heated and softened thermoplastic plastic sheets such as PVC and PET are blister-formed into various shapes of vacuum covers, blister trays, bubble shells, etc. through molds, and the blister machine usually needs to be equipped with a feeding structure to transport the blister film to the inside of the blister machine.

[0003] In the prior art, patent number CN202223153290.2 proposes a blister packaging film blister coil feeding mechanism, in which two slides are pushed to move relative to each other by a supporting spring, thereby pushing two dust removal rollers to fit the outer surface of the blister coil, so that the dust removal rollers can be completely in contact with the outer surface of the blister coil, and the dust attached to the surface of the blister coil can be completely cleaned by the dust removal rollers, thereby avoiding the impact of dust accumulation on product quality. The dust removal roller of the patent with patent number CN202223153290.2 needs to be replaced or the surface of the dust removal roller needs to be cleaned after too much dust adheres to the surface. When the dust removal roller is replaced or cleaned, the blister machine needs to be stopped, thereby delaying the production of blister boxes. Therefore, a dust-proof feeding structure for a blister machine is proposed. Utility Model Content
