Film delivering and receiving device for sealing of wide-mouth barrel

Abstract

The invention discloses a film feeding and collecting device for wide-mouth barrel sealing, which comprises a motor, a film feeding roller, and a film collecting roller. The motor is connected with a first sprocket, and the first sprocket is respectively connected to the The second sprocket is connected to the third sprocket, the second sprocket is connected to the film feeding roller through the film feeding shaft, the third sprocket is connected to the fourth sprocket through a hinge, and the fourth sprocket is The film shaft is connected with the film collecting roller, and the second sprocket is slidingly connected with the film feeding shaft. The present invention is a film feeding and collecting device used for wide-mouth barrel sealing. The device has a simple structure and is easy to operate. The sprocket and the film feeding shaft are designed to be slidingly connected, and the sprocket is used to slip to overcome the mismatch between film feeding and film collection. , can effectively reduce the tension of the sealing film and prevent the sealing film from being torn; it can effectively reduce the production cost and improve the sealing efficiency of the jar.

Description

technical field [0001] The invention relates to the technical field of jar sealing, in particular to a film feeding and collecting device for sealing jars. Background technique [0002] At present, the general wide-mouth barrels on the market are sealed by adding a sealing ring between the lid and the opening of the barrel wall to achieve the sealing effect, but in some special cases, the wide-mouth barrel with this structure will have leakage problems, especially Leakage occurs when the jar is tilted or tipped over. For some wide-mouth barrels, a layer of sealing film is added to the wide-mouth barrel to enhance the sealing effect and avoid leakage problems, but the operation of feeding and collecting the sealing film is more complicated. The sealing film is torn, which not only increases the production cost, but also reduces the sealing efficiency of the wide mouth barrel. Contents of the invention [0003] In order to solve the above problems, the present invention pr...
