Commodity packaging device capable of realizing isochronous heat sealing and avoiding wrinkles

Abstract

The invention relates to the technical field of commodity wholesale trade, and discloses a commodity packaging device capable of realizing isochronous heat sealing and avoiding wrinkles. The commoditypackaging device comprises a base, through cooperative use of a ratchet wheel disc, a positioning rib, an electromagnet, a first rotating shaft, an outer sleeve rod, a second rotating shaft and rotating wheels, and a bag automatically stops moving during heat sealing by means of capacitance change, so that the condition that a packing bag cannot be sealed due to wrinkles can be avoided, and the sealing effect is improved. The packing bag is moved again after being sealed and transferred to the next processing step, through cooperative use of cams and heating plates, the heating time during heat sealing is kept consistent, and the situation that due to insufficient heating time, a plastic bag is insufficient in thermoforming, or due to too long time, thermoforming is excessive, is avoided,and the sealing intelligence of the entire device is improved. Through cooperative use of a first disc and a limiting sleeve, two steps of movement stopping of the packing bag and automatic isochronous heat sealing are linked, the linkage performance of the whole device is improved, and operation is simpler.

Description

technical field [0001] The invention relates to the technical field of commodity wholesale trade, in particular to a commodity packaging device capable of isochronous heat sealing and avoiding wrinkles. Background technique [0002] In order to reduce the cost of purchase and meet the demand for large-scale purchases, customers often wholesale goods in batches, some of which need to be packaged to facilitate subsequent transportation and storage. In the process of packaging, heat sealing is usually required The traditional heat sealing machine is relatively simple to set up. On the one hand, the heating time cannot be controlled during the heat sealing process. If the heating time is too long, the packaging bag will be overheated, resulting in damage to the bag, and subsequent packaging needs to be repackaged. , when the heating time is too short, it will cause insufficient heating of the packaging bag, which will cause the bag to not be fully bonded, and the packaging needs...

[0002] In order to reduce the cost of purchase and meet the demand for large-scale purchases, customers often wholesale goods in batches, some of which need to be packaged to facilitate subsequent transportation and storage. In the process of packaging, heat sealing is usually required The traditional heat sealing machine is relatively simple to set up. On the one hand, the heating time cannot be controlled during the heat sealing process. If the heating time is too long, the packaging bag will be overheated, resulting in damage to the bag, and subsequent packaging needs to be repackaged. , when the heating time is too short, it will cause insufficient heating of the packaging bag, which will cause the bag to not be fully bonded, and the packaging needs to be reheated later, and the packaging effect will be poor. On the other hand, the product is still moving during the heat sealing process, thus Wrinkles are prone to appear at the seal, which will not only affect the appearance but also affect the heat sealing effect
