Film expansion mechanism of coating machine

Abstract

The invention discloses a film-expanding mechanism for a film packaging mechanism, which comprises structures of a film feeding wheel, a support, a guide wheel bracket, a guide inner wheel, a guide wheel limiting rod, a guide inner wheel base, and a guide outer wheel. A guide wheel bracket arranged symmetrically is fixed on a vertical plane on the upper end of the support; the guide outer wheel is arranged in the guide wheel bracket; a guide outer wheel shaft on the upper end of the guide wheel bracket is upwards connected with a guide wheel limiting rod, and the upper end of the guide wheel limiting rod is upwards connected with a guide floating lever; and a guider floats in an annular film. The film packaging machine arranged in filling pipeline accords with the requirements on small batch and various-variety packaging automation, aligns quickly, fills up the blank domestically, and greatly reduces the input of fixed assets; the film packaging quality is high, and the percent of pass is more than 98 percent; and because of the simple structure, the fault rate is small, the maintenance is convenient, and the packaging quality of foods and medicines is improved, thus the film-expanding mechanism is advantageous to improve the international competitive capacity of foods and pharmaceutical industries.

Description

1. Technical field: [0001] The film expansion mechanism of the film covering machine of the present invention relates to the technical field of design and manufacture of packaging machinery, in particular to the technical field of design and manufacture of filling machinery, and is applied to the sleeve labeling and sealing of bottled containers. 2. Background technology: [0002] At present, there are similar machines in the international market, but there is no such machine in the domestic market. In China, the labels are set by hand, and the productivity is low. The foreign sets of labels and sealing machines have a single application range and cannot be adjusted in the filling line. , the setting of the mechanism can only adapt to one product. At the same time, due to its relatively complex structure, it causes high prices, many failures, and difficult maintenance. It cannot meet the design requirements of domestic multi-variety and small-batch production, which restricts...
