Embodiment 1

[0017] Embodiment one: see attached figure 1 , 3 and 4, the present invention provides a roll film installation device, including two parallel baffles 1, 2, a spacer 3 arranged between the two baffles, the key is: in the hollow cavity of the spacer 3 A film tensioning assembly is provided, and the above-mentioned film tensioning assembly includes a driving shaft 4 with a forward-rotating threaded portion 4-1 and a reverse-rotating threaded portion 4-2, respectively connected to the forward-rotating threaded portion 4-1 and the forward-rotating threaded portion 4-1 of the driving shaft 4 The two tensioning drive blocks 5 that are threaded with the anti-rotation thread part 4-2, the tensioning block 6 that is limited in the limit groove 3-1 arranged along the axial direction of the spacer 3, the above two tensioning drive blocks 5 The tensioning driving part 5-1 is symmetrically limited on both sides of the bottom of the tensioning block 6, and the above-mentioned tensioning bl...

Embodiment 2

[0037] Embodiment 2: The difference from Embodiment 1 is that a tension block reset assembly is provided between the drive shaft 4 and the tension block 6, and the tension block reset assembly includes a set on the drive shaft 4 and is located on the forward-rotating threaded part 4- 1 and the mounting sleeve 7 between the anti-rotation threaded part 4-2 and the return spring 8 arranged between the installation sleeve 7 and the tension block 6, the above-mentioned return spring 8 is an extension spring. The mounting sleeve 7 is only sleeved on the driving shaft 4, but will not rotate with the driving shaft 7.

[0038] In this embodiment, when the tensioning block 6 protrudes from the limiting groove 3-1, the return spring 8 is pulled to give the tensioning block 6 an inward pulling force to facilitate the reset of the tensioning block 6 . Obviously, no matter the return spring 8 is a tension spring or a compression spring, the force it provides to the tension block 6 is the fo...

Abstract

The invention, which belongs to the technical field of plastic packaging of paper money, discloses an apparatus for installing a rolling film. The apparatus comprises two baffle plates arranged in parallel and a spacer bush arranged between the two baffle plates. The apparatus is characterized in that a rolling film expanding assembly is arranged in a hollow cavity of the spacer bush and consists of a driving rotating shaft having a forward-rotation thread part and a reverse-rotation thread part, two expansion driving blocks in a screw-thread fit relationship with the forward-rotation thread part and the reverse-rotation thread part of the driving rotating shaft respectively, and an expansion block limited in a limit groove arranged along the axial direction of the spacer bush. Expansion driving parts of the two expansion driving blocks are limited at the two sides of the bottom of the expansion block symmetrically; and the expansion block has freedom of movement along the radial direction of the spacer bush under driving from the driving rotating shaft. When the apparatus is used for pre coating, the axial and radial directions of a pre-coated film can be localized with high positioning precision. And when the apparatus is used for rolling a wasted film, the expansion block extends out of the limit groove of the spacer bush in an initial state; after the wasted film winds fully, the driving rotating shaft is rotated to realize contraction of the expansion block, so that the wasted film can be taken down conveniently.

Description

technical field [0001] The invention belongs to the technical field of banknote plastic sealing, and in particular relates to a rolling film installation device applied to a banknote plastic sealing packaging machine or a banknote plastic packaging assembly line. Background technique [0002] Renminbi is the legal currency in circulation in my country. In the circulation process of RMB, the safe and reliable packaging and storage of banknotes not only has economic value, but also has very important significance for the currency security of our country. At present, due to improper packaging of banknotes, the problem of banknote damage is more serious, and the bank's storage and maintenance costs are increased. Banknote packaging has extremely high requirements on safety, and the banknotes cannot be scattered during transportation, and the outer packaging cannot be broken. The process of banknote return and sorting in developed countries is: use environmentally friendly heat...
