Description

Technical Field

[0001] The invention relates to a curling device, in particular to a bowl edge curling device for a paper bowl machine for processing anti-scalding paper bowls, belonging to the technical field of paper bowl processing. Background Art

[0002] With the development of industrial technology, the modern food industry has become more and more perfect. Due to the accelerated pace of modern society, modern people have less and less time to cook for themselves. As a result, a lot of paper bowls are needed in the food industry to fill processed industrial foods. Anti-scalding paper bowls are mass-produced during processing and production. As a result, the rims of the paper bowls need to be curled during the processing. The curling is done by a forming mold. The forming mold has a cup mold and a curling mold. The curling mold will cooperate with the lower mold to curl the rim. The cup body will be put outside the cup mold, and the cup bottom paper will be placed directly on the bottom of the cup mold.

[0003] Among them, the "disposable paper bowl mold" disclosed in the application number "202322887025.5" "comprises a mold body, a guide rod is provided on the mold body, and a curling structure is installed on the guide rod, the curling structure comprises a lifting sleeve, a threaded sleeve and a curling assembly, the lifting sleeve is fixedly connected to the threaded sleeve, and the lifting sleeve and the threaded sleeve are penetrated by through holes." In the present invention, the curling assembly is threadedly connected to the threaded sleeve through the set curling structure. When needed, the curling assembly can be quickly removed from the threaded sleeve, which is convenient for replacing curling assemblies with curling grooves of different models, thereby improving the adaptability of the entire mold. The curling assembly is installed in a threaded connection manner, has high stability after installation, and is easy to install and disassemble. A positioning ring is set in the curling assembly, which is used in conjunction with the positioning groove on the mold body. It can play a guiding and positioning role during the mold closing process, ensure the accuracy of the mold closing, and further ensure the normal progress of the curling work.

[0004] However, the above method still has the following defects: different types of crimping components are installed by threading the crimping components at the threaded sleeve; however, during the installation and removal of the crimping components, the threaded connection method is adopted, which requires the user to prepare special tools to perform tightening or loosening operations, which undoubtedly increases the labor intensity of the staff. Furthermore, when different types of crimping components need to be replaced, the cumbersome installation and removal process will delay the operation progress, and ultimately have an adverse effect on the production efficiency of paper bowls.
