Description

Technical Field

[0001] The utility model relates to the technical field of heat sealing of air column bags, in particular to a heat sealing device used for sealing air column bags. Background Art

[0002] Air column bags, also known as cushioning air column bags, inflatable bags, bubble column bags, and columnar inflatable bags, are new packaging materials filled with natural air. Air column bags use physical principles to inflate once, fill the entire row, and automatically lock the air to form a diving chamber. When damaged, only the damaged air column part will fail, and the remaining air columns will be completely unaffected, still maintaining the protective effect, convenient for long-term storage and transportation of airtight anti-seismic protection, and air column-type comprehensive cushioning protection to minimize the damage rate. During the production process of air column bags, the air column bags are heat-sealed by a heat-sealing device to form a seal.

[0003] When the existing heat sealing device seals the air column bag, it is generally adopted to manually hold the air column bag, and the bag mouth of the air column bag needs to be manually placed under the heating block for heat sealing. Not only is the degree of automation low, but the workers are prone to accidentally touch the heating block during the process, which may cause burns. There are certain safety hazards. For example, a packaging air column bag heat sealing device disclosed in application number CN201921469120.0, after the heat sealing device in this patent heat seals the air column bag, in order to facilitate storage and transportation, it is often necessary to roll up the air column bag. If the sealed air column bag cannot be rolled up, additional manual or mechanical means are required to complete this step, which requires more manual intervention and operation, increases the difficulty of operation and labor intensity, and leads to reduced production efficiency.

[0004] Therefore, it is necessary to invent a heat sealing device for sealing air column bags to solve the above problems. Utility Model Content

[0026] Working principle of this utility model:

[0027] Refer to the instruction manual Figure 1-5When using the utility model, firstly, the heat sealing device is stably placed in a suitable position, and the heat sealing device is connected to an external power supply so that the heat sealing device is in a powered-on working state, and then the rolled air column bag roll is put on the unwinding wheel 10, and one end of the air column bag roll is wound around the guide wheel 11 and extended to between the lower horizontal plate 12 and the upper horizontal plate 14, and then the driving motor 2 is started, and the driving motor 2 can drive the No. 1 pulley 3 to rotate, and the No. 1 transmission belt 5 can drive the No. 1 pulley 3 and the No. 2 pulley 4 to rotate synchronously, thereby the No. 2 pulley 4 drives the No. 1 rotating shaft 9 and the unwinding wheel 10 to unwind the air column bag, and when the No. 1 rotating shaft 9 rotates, it drives the No. 3 pulley 6 to rotate synchronously, thereby the No. 4 pulley 7 can be driven by the No. 2 transmission belt 8. It rotates synchronously with the No. 3 pulley 6, so that the No. 4 pulley 7 can drive the No. 2 rotating shaft 18 and the winding wheel 19 to rotate synchronously. At this time, the air column bag is transmitted and continuously inflated at the inflation mechanism 17, and then the upper cross plate 14 is driven by two cylinders 20 to descend and contact the air column bag. As a result, the inflated air column bag is squeezed against each other by the heat-pressing wheels 16 on the lower cross plate 12 and the upper cross plate 14, and the bag opening of the air column bag is heat-sealed. The sealed air column bag is rolled up by the winding wheel 19, thereby quickly completing the sealing of an air column bag. In this process, only the process of arranging the air column bags requires manual participation, and the subsequent processes do not require manual participation of the staff, thereby avoiding the risk of the staff being scalded by the heat-pressing wheel 16, and also improving the sealing speed of the air column bag.
