Embossing device for plastic film bag

Abstract

The invention relates to an embossing device for a plastic film bag, and belongs to the field of plastic embossing equipment. The embossing device comprises a rack, an embossing roller assembly, an upper pressing roller assembly and a lower supporting roller assembly; the upper pressing roller assembly comprises two upper rubber pressing rollers and a first driving mechanism; and the lower supporting roller assembly comprises two lower rubber supporting rollers and a second driving mechanism; the upper rubber pressing rollers and the lower rubber supporting rollers are both connected with the rack in a relatively rotating mode; the embossing roller assembly comprises a connecting support, a first embossing roller and a second embossing roller; the first embossing roller is located between the two upper rubber pressing rollers, and the second embossing roller is located between the two lower rubber supporting rollers; embossing gaps for a film bag to pass through are reserved between the first embossing roller and the upper rubber pressing rollers and between the second embossing roller and the lower rubber pressing rollers; and the first embossing roller and the second embossing roller are both used for embossing the film bag. The embossed patterns protrude outwards from the interior of the film bag, so that the friction coefficient of the outer surface of the film bag is effectively increased, and the thin film bag is convenient to take and stack.

Description

technical field [0001] The present application relates to the field of plastic embossing equipment, in particular to an embossing device for plastic film bags. Background technique [0002] Plastic film is mostly produced by blown film method. During production, the plastic raw material is melted and extruded from the circular extrusion port of the blown film machine head, blown into a cylindrical film bubble, and then gradually flattened by the herringbone splint. Then the film is flattened by the traction nip roller to form a double-layer film. Film bags are widely used in the market, and most film bags need to be embossed in order to meet the needs of packaging and aesthetics. [0003] The relevant announcement number is the Chinese utility model patent of CN2853379, which discloses a production device for embossed plastic film used in vacuum packaging, which includes a casting type plastic film production mechanism, and the rear of the casting type plastic film producti...
