Description

Promote gift box L type seal cutting machine structure of thermal contraction homogeneity Technical Field The utility model belongs to the technical field of sealing and cutting machines, and particularly relates to an L-shaped gift box sealing and cutting machine structure for improving heat shrinkage uniformity. Background In the modern gift packaging industry, the heat shrinkage packaging technology is widely applied because the heat shrinkage packaging technology can enable the package to closely fit the appearance of the gift box, and provides a packaging effect with attractive appearance and strong protection. The gift box L-shaped sealing and cutting machine is used as key equipment in the heat shrink packaging process, and has the main function of sealing and cutting the gift box sleeved with the heat shrink film, so that the heat shrink film can shrink and tightly wrap the gift box in the subsequent heating process. The conventional L-shaped gift box sealing and cutting machine structure generally comprises a sealing and cutting table, a sealing and cutting mechanism, a conveying device and other basic components. The sealing and cutting mechanism generally comprises a sealing cutter and a heating element which are arranged oppositely, and in the sealing and cutting process, the heating element is used for heating the heat shrinkage film to soften the heat shrinkage film, and then the sealing cutter is used for cutting off and sealing the heat shrinkage film at the edge of the gift box. However, this conventional structure has various drawbacks, which seriously affect the uniformity of heat shrinkage. Firstly, the sealing cutter of the traditional sealing cutter is simpler in structure and is mostly of a flat plate type fixed design. When the gift boxes with different sizes and shapes are faced, the sealing and cutting pressure and angle cannot be flexibly adjusted, so that the stress of the heat shrinkage film at the sealing and cutting position is uneven. For example, when the corner of the gift box is arc-shaped or has a special shape, the flat plate type sealing cutter is difficult to be completely attached, so that the sealing effect of the heat shrinkage film at the corner is poor, the condition of wrinkling or poor sealing is easy to occur, and the uniformity of heat shrinkage is further affected. Secondly, the layout of the heating elements of the traditional sealing and cutting machine is not reasonable enough. The heating elements are often simply distributed near the sealing and cutting knife, and the heating requirement of the heat-shrinkable film in the whole sealing and cutting area is not fully considered. This results in differences in the rate and extent of heating of the heat shrink film at different locations, portions closer to the heating element may be over heated, while portions farther from the heating element may be under heated. In the subsequent heat shrinkage process, the heat shrinkage film heated unevenly can shrink to different degrees, so that the surface of the packed gift box has the problems of uneven and wrinkled appearance, and the aesthetic degree and quality of the package are seriously affected. In summary, the traditional L-shaped gift box sealing and cutting machine structure has a plurality of defects in the aspect of heat shrinkage uniformity, and is difficult to meet the requirements of the modern gift packaging industry on high quality and exquisite packaging. Therefore, research and development of the gift box L-shaped sealing and cutting machine structure capable of effectively improving the uniformity of heat shrinkage has important practical significance.
