Automatic face mask packer

Abstract

An automatic face mask packer comprises a rack, a face mask conveying mechanism, a bag molding device and a sealing device, wherein the sealing device comprises a drawing mechanism, a longitudinal sealing mechanism, a transverse sealing and cutting mechanism, a conveyor belt and an exhaust mechanism; the longitudinal sealing mechanism comprises a longitudinal heating mechanism and a longitudinal pressure-tight sealing mechanism; the longitudinal heating mechanism comprises two longitudinal heater strips which are arranged side by side right and left; the drawing mechanism, as well as the longitudinal pressure-tight sealing mechanism, comprises a first runner and a second runner which are in press fit with each other and rotate relative to each other; the conveyor belt is provided with an advancing segment which moves from front to back; the drawing mechanism and the longitudinal sealing mechanism are located right above the advancing segment of the conveyor belt; the exhaust mechanismis located between the longitudinal sealing mechanism and the transverse sealing and cutting mechanism and comprises an exhaust compression roller in a left-and-right direction; and the exhaust compression roller and the advancing segment of the conveyor belt are in pressure fit with each other. According to the automatic face mask packer, gas in a package film which is longitudinally sealed can be exhausted by the sealing device to ensure that the transverse sealing and cutting mechanism can perform transverse sealing and cutting in an accurate position of a transverse sealing part, such thatthe sealing quality is improved.

Description

technical field [0001] The invention relates to the technical field of packaging machinery, in particular to an automatic mask packaging machine. Background technique [0002] At present, packaging film (such as plastic film or aluminum-plastic composite film) is usually used to make a packaging bag and pack the mask in it to protect the mask, keep the mask hygienic, and be easy to store and carry. [0003] An existing mask packaging machine comprises a frame, a mask conveying mechanism, a bag forming device and a sealing device, and the mask conveying mechanism, the bag forming device and the sealing device are sequentially installed on the frame from front to back. When working, the packaging film is first bent into a U shape by the bag forming device (the cross-section of the packaging film is U-shaped), and then the mask is sent into the U-shaped packaging film by the mask conveying mechanism, and finally sealed The device seals the U-shaped packaging film to make a pac...

AI Technical Summary

Problems solved by technology

However, there is often a certain amount of gas in the packaging film that is longitudinally sealed by the longitudinal sealing mechanism, which will make it difficult for the horizontal sealing and cutting mechanism to perform horizontal sealing and slitting at the exact position of the horizontal sealing position, easily producing defective and waste products, and The finished packaging bag will occupy a large space and is not convenient for storage and portability
