Packaging sealing device using new material as base material

Abstract

The invention relates to the technical field of automatic packaging mechanical equipment, and discloses a packaging sealing device using a new material as a base material. The device comprises a shell, wherein pressing plates are movably connected with the interior of the shell. The neatening operation is automatically controlled to be conducted, and the follow-up heat sealing operation is triggered by utilizing a capacitance principle; the air in a packaging bag is automatically extruded, a bag opening is closed, the content of the air in the packaging bag is reduced, the size of a packaged finished product is reduced, the situation that the packaged product is exploded due to the excessive air content in the packaging bag is effectively avoided, the opening degree of the bag opening is reduced, the problem that the bag opening is expanded due to the fact that the packaged product bears the vibration effect of equipment in the transferring process is solved, and the probability that the bag opening cannot be effectively sealed due to sealing dislocation and early shrinking of the bag opening is reduced; and double-side sealing is automatically conducted on the neatened packaging bag, the sealing state is temporarily kept, the sealing tightness is enhanced, the probability that the packaged finished product falls off due to the fact that the sealing is not tight is reduced, andtransfer of the packaged finished product is facilitated.

Description

technical field [0001] The invention relates to the technical field of automatic packaging machinery and equipment, in particular to a packaging sealing device based on new materials. Background technique [0002] Packaging is one of the common processes in the product processing process. In addition to the function of packaging boxes, packaging also has the effect of modifying items, which has a certain impact on the choice of consumers. In order to keep the product in a sealed state, ensure its quality, and avoid product loss, the packaging container is often sealed with the help of a sealing machine. Due to the vibration of the conveying device during the transfer of the product through the conveying device, the product in the packaging bag continuously impacts the packaging bag, causing the opening of the packaging bag to expand. When the sealing machine seals it, the opening of the bag is prone to appear. Before bonding, the two ends of the bag mouth will shrink premat...
