Abstract

The utility model discloses a web flattening mechanism. The web flattening mechanism comprises a support frame, a support shaft is arranged on the support frame, the support shaft is provided with a flattening roller in a sleeved mode, the flattening roller is formed by two flattening roller bodies with spiral grooves, the two flattening roller bodies with the spiral grooves are coaxially and symmetrically jointed in a split mode, and the spiral grooves on the flattening roller bodies tilt from inside to outside. According to the structure, due to the fact that the flattening roller is formed by the two flattening roller bodies with the spiral grooves, the two flattening roller bodies with the spiral grooves are coaxially and symmetrically jointed in a split mode, and the spiral grooves on the flattening roller bodies tilt from inside to outside. Therefore, when paper passes through the flattening roller bodies, the spiral grooves tilting from inside to outside on the flattening roller bodies enable the paper to be quickly expanded and flattened only from the middle to both ends. Compared with the prior art, the web flattening mechanism has a more rapid flattening speed and better flattening effect.

Description

The flatten mechanism of paper in reel

Technical field

The utility model relates to a kind of flatten mechanism of paper in reel.

Background technology

The flatten mechanism of paper in reel is a kind of mechanical device that paper in reel is launched and paves, and described flatten mechanism comprises support, is equiped with pivot shaft on the described support; Be arranged with leveling roller on the pivot shaft; But the leveling roller in the existing paper in reel flatten mechanism is an integral type band spiral fluted leveling roller body, and the plug helix on the said leveling roller body be the straight trough perpendicular to the leveling roller central axis, therefore when paper passes through the leveling roller body; Straight trough on the leveling roller body is to impel paper to extend simultaneously until flattening to all directions; Though such structure also can be with sheet spread, paper is slowly to flatten towards all directions from all directions, and flattening speed is slow; And all directions are traction each other easily, and the flattening effect is relatively poor.

Summary of the invention

To the deficiency of prior art, the utility model provide a kind of flatten speed faster, flatten the better paper in reel flatten mechanism of effect.

For realizing above-mentioned purpose; The utility model provides a kind of flatten mechanism of paper in reel; Comprise support, be equiped with pivot shaft on the described support, be arranged with leveling roller on the pivot shaft; Described leveling roller is spliced with rotational symmetry by two band spiral fluted leveling roller bodies, and the plug helix on the said leveling roller body tilts from inside to outside.

The beneficial effect of the utility model is: adopt said structure; Because the leveling roller that the utility model provided is spliced with rotational symmetry by two band spiral fluted leveling roller bodies; And the plug helix on the said leveling roller body tilts from inside to outside, therefore when paper during through the leveling roller body, on the leveling roller body from inside to outside the bevelled plug helix will impel paper only towards by the centre to two ends rapidly expansion pave; Compare prior art, it flattens, and speed is faster, the flattening effect is also better.

The utility model can further be set to be equiped with bearing between pivot shaft and the leveling roller body.

The specific embodiment

Provided a kind of flatten mechanism of paper in reel like Fig. 1, shown in 2; Comprise support 1; Be equiped with pivot shaft 2 on the described support 1, be arranged with leveling roller 3 on the pivot shaft 2, described leveling roller 3 is spliced with rotational symmetry by the leveling roller body 31 of two band plug helixs 311; And the plug helix 311 on the said leveling roller body 31 tilts from inside to outside, is equiped with bearing 4 between pivot shaft 2 and the leveling roller body 31.Adopt said structure; Because the leveling roller 3 that the utility model provided is spliced with rotational symmetry by the leveling roller body 31 of two band plug helixs 311; And the plug helix 311 on the said leveling roller body 31 tilts from inside to outside, therefore when paper during through leveling roller body 31, on the leveling roller body 31 from inside to outside bevelled plug helix 311 will impel paper only towards by the centre to two ends rapidly expansion pave; Compare prior art, it flattens, and speed is faster, the flattening effect is also better.

Claims

1. the flatten mechanism of a paper in reel; Comprise support; Be equiped with pivot shaft on the described support; Be arranged with leveling roller on the pivot shaft, it is characterized in that: described leveling roller is spliced with rotational symmetry by two band spiral fluted leveling roller bodies, and the plug helix on the said leveling roller body tilts from inside to outside.
