Embodiment Construction

[0009] All features disclosed in this specification, or all disclosed methods or steps in the process, except for mutually exclusive features and / or steps, can be combined in any manner.

[0010] Any feature disclosed in this specification, unless specifically stated, can be replaced by other equivalent or equivalent alternative features. That is, unless otherwise stated, each feature is just one example of a series of equivalent or similar features.

[0011] Such as figure 1 The tension roller shown includes a roller body 1. Two guide grooves 2 are opened on the roller body 1. The guide grooves 2 extend spirally from the middle position of the roller body 1. The tension roller of the present invention , The two guide grooves 2 are symmetrical to each other. In the present invention, since two guiding grooves extending outward in a spiral shape are provided, the film can be stretched and stretched during the rotation process, which ensures that the film does not wrinkle.

Abstract

The invention discloses a tensioning roll which comprises a roll body (1). Two guide grooves (2) are formed in the roll body (1) and extend outwards from the middle of the roll body (1) to form a spiral shape. According to the tensioning roll, the two guide grooves extending outwards in the spiral shape are formed, so that a film can be expanded and tensioned in the rotating process, and it is guaranteed that the film cannot be crinkled.

Description

Technical field [0001] The invention relates to the field of printing machinery, in particular to a tension roller. Background technique [0002] The tension rollers in the existing printing machinery are only ordinary rollers with smooth surfaces. During the printing process, additional tensioning devices need to be added, otherwise the film will wrinkle after a period of printing. Summary of the invention [0003] In order to solve the problem of poor tensioning effect of the current tensioning roller, the present invention provides a tensioning roller, which includes a roller body 1 on which two guide grooves 2 are opened. 2 extends spirally from the middle position of the roller body 1 outward. [0004] In the tension roller of the present invention, the two guide grooves 2 are symmetrical to each other. [0005] The beneficial effects of the present invention are: [0006] In the present invention, since two guiding grooves extending outward in a spiral shape are provided, the f...
