Description

UV conduction band printer of adjustable guipure rate of tension

Technical Field

The utility model relates to a UV conduction band printer especially relates to the guipure structure module of UV conduction band printer.

Background

The UV conduction band printer is generally used for printing materials such as super-transparent stickers, car stickers, flexible films, canvas, lamp sheets and the like, and the printing materials are basically printed in rolls. During printing, the material is attached to a mesh belt of a UV printer. Need the guipure to possess higher rate of tension in order to guarantee to print quality, current UV conduction band printer adjusts the guipure rate of tension through adjusting the conduction band roller. In the process of tensioning the mesh belt by adjusting the backward movement of the belt guide roller, the belt guide roller can be bent towards the middle due to the tension of the mesh belt, so that the mesh belt is tensioned at two ends, and the middle part is loosened. Because the tight centre in both ends is loose, can influence the printing material laminating degree in printing process, and then influence printing quality.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the UV conduction band prints the inconsistent defect of guipure rate of tension that causes easily when adjusting the guipure.

In order to solve the technical problem, the UV conduction band printer of adjustable guipure rate of tension, roller and guipure behind roller, conduction band front roller, conduction band, the guipure suit is on roller behind roller and the conduction band before the conduction band, be provided with adjusting bolt behind the conduction band on the roller, conduction band front roller side is provided with the top roller device.

According to the further optimization of the technical scheme, the top roller device is composed of a top roller and an adjusting screw rod, and the top roller is arranged at the end part of the adjusting screw rod.

According to the technical scheme, the jacking roller is composed of the supporting shaft, the V-shaped supporting frames and the roller shafts, the supporting shaft is vertically arranged at the end part of the adjusting screw rod, the V-shaped supporting frames are symmetrically arranged at the two ends of the supporting shaft, the roller shafts are arranged at the end parts of the V-shaped supporting frames at the two sides, and the roller shafts are arranged in the middle of the V-shaped supporting frames at the two sides.

According to the further optimization of the technical scheme, two ends of the roll shaft are fixed with the V-shaped support frame through bearings.

According to the further optimization of the technical scheme, the adjusting screw rod is provided with the mounting plate, the mounting plate and the adjusting screw rod are movable, and nuts are arranged on two sides of the mounting plate.

According to the technical scheme, the V-shaped support frame supports against the guide belt front roller, and the adjusting screw is fixed on the support frame between the guide belt front roller and the guide belt rear roller through the mounting plate.

The UV conduction band printer of adjustable guipure rate of tension of this scheme has eliminated the deflection in the middle of conduction band front-end roll and the conduction band back-end roll, makes the printing material step-by-step more accurate, has further improved the printing precision.

Detailed Description

The utility model provides a UV conduction band printer of adjustable guipure rate of tension is the improvement of going on current UV conduction band printer's basis, has all left out to the department that does not improve, mainly explains in detail to the department that improves.

Referring to fig. 1, the UV conduction band printer capable of adjusting the tensity of the conduction band comprises a conduction band front roller 2, a conduction band rear roller 1 and the conduction band, wherein the conduction band is sleeved on the conduction band front roller 2 and the conduction band rear roller 1, and the conduction band front roller 2 and the conduction band rear roller 1 form a synchronous rotating structure through the conduction band. And an adjusting bolt 3 is arranged on the guide belt rear roller 1, and a top roller device 5 is arranged on the side edge of the guide belt front roller. The top roller device 5 is arranged in the middle of the front roller 2 and the back roller 1 of the guide belt.

Referring to fig. 2 to 4, the top roller device 5 is composed of a top roller 51 and an adjusting screw 52. The top roller 51 mainly comprises a support shaft 511, a V-shaped support frame 512 and a roller shaft 513.

Wherein the support shaft 511 is fixed to an end of the adjustment screw 52, and the support shaft 511 and the adjustment screw 52 are vertically disposed. The support shaft 511 may be fixed to the adjustment screw 52 by welding or may be fixed to the adjustment screw 52 by screw engagement.

V-shaped supporting frames 512 are symmetrically arranged at two ends of the supporting shaft, bearings 514 are arranged at two ends of each V-shaped supporting frame, and the roll shafts 513 are arranged in the bearings 514. The roller shaft 513 is disposed in parallel with the support shaft 511.

The adjusting screw 52 is sleeved with a movable mounting plate 521, the mounting plate 521 is fixed on the support frame 4 between the guide belt front roller 2 and the guide belt rear roller 1 through a bolt sleeve, the adjusting screw 52 is horizontally arranged, meanwhile, the roller shaft 513 is attached to the guide belt front roller 2, and the adjusting screw 52 is locked through a nut 522.

When the top roller device 5 is not provided, the adjusting bolt 3 is used for enabling the guide belt rear roller 1 to move backwards to tension the mesh belt, the guide belt front roller 2 and the guide belt rear roller 1 can flex towards the middle due to the tension of the mesh belt, so that the two ends of the mesh belt are tensioned, and the middle part of the mesh belt is loosened due to the flexing of the guide belt front roller 2 and the guide belt rear roller 1. After the top roller assembly 5 is installed, the adjusting screw 52 is now adjusted by the nut 522 to advance the top roller 51 toward the front belt guide roller 2 to offset the deflection of the front belt guide roller, thereby tensioning the middle portion of the belt as well as the ends. When the guide front roller 2 rotates, the roller shaft 513 also rotates, and the deflection of the guide front roller can be continuously kept offset.
