Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tote bag manufacturing, and in particular to a hot pressing device for one-piece molded tote bags. Background Technology
[0002] Plastic tote bags are bags made primarily of plastic (common plastics include polypropylene, polyester, nylon, etc.). They are essential items in people's daily lives and are often used to carry other items.
[0003] Existing one-piece molded tote bag hot pressing devices, such as the hot pressing mechanism for processing the bag opening disclosed in utility model patent application number 202322111753.7, mainly include a hot pressing frame, a first stabilizing roller group and a second stabilizing roller group respectively longitudinally arranged at the middle of the upper and lower ends of the hot pressing frame, and a first hot pressing mechanism and a second hot pressing mechanism symmetrically arranged at the left and right ends of the middle of the hot pressing frame. In use, the first and second opening seats on the bag opening protective belt assembly open the bag opening after folding. The hot pressing protective belt strips on the first and second hot pressing protective belt strip assemblies isolate the outer ends of the bag opening from the hot pressing blocks on the first and second hot pressing mechanisms. Then, the operator clamps two reinforcing pieces with a clamping device and inserts them into the inner ends of the bag opening. Then, the first and second hot pressing mechanisms work synchronously, causing the two hot pressing blocks to move towards the protective belt strip in the middle of the bag opening and fit together.
[0004] However, most existing hot pressing devices have low integration and still require special equipment for cutting after hot pressing, which is very troublesome. Moreover, the plastic film is easily subjected to uneven stress during the hot pressing process, which affects the hot pressing effect. Utility Model Content
