Abstract

A pulling device which is pulled by air is composed of two pulling elements which are collocated symmetrically and have identical structure and composing, which is characterized in that holdfasts of upper and lower roller of each pulling element are arranged on a straight guide rail. The straight guide rail is arranged on a pivot shaft which is provided with components of angular adjustment. Adjust pressing point components of the upper and lower roller are arranged on the straight guide rail. Pressing points of the upper and lower roller are adjusted on the common tangent of exoteric circularity of a guide roller and a screw roller. The guide roller is used for leading in flexible filmy materials and the screw roller is used for leading out flexible filmy materials. Each pulling element is also provided with a cylinder which is equipped with an air pressure adjustment component and provides folding power of the upper and lower roller. The pulling device can achieve novel pulling mechanism, advanced design of structure, good property, high accuracy and good pulling effect. Flexible filmy materials which need to be pulled do not contact with geometric curving side of the pulling element of the pulling device, so pulling device can hard bring the physical deformation, and the surface of the pulling device can not be abraded up to wastrels. The pulling device has high adaptability of pulling which is made of different kinds of flexible filmy materials, especially flexible filmy materials of wider breadth.

Description

A kind of pneumatic traction flattening device

Technical field the utility model relates to and spreads out soft thin material, relates in particular to a kind of pneumatic traction flattening device.

The plastic sheeting that background technology is common, paper, soft thin material such as cloth, in technological process, often be easy to produce the fold phenomenon, have a strong impact on and cut, normally carrying out of winding process, need soft thin material be stretched to both wings by flattening device, tighten, in order to avoid produce the wrinkle fold, influence is cut, rolling quality and aesthetic appearance, existing flattening device, comprise Chinese patent CN2225455Y, " a kind of diaphragm that is used for removes the stretcher that wrinkles " that CN2466178Y and CN2496641Y announce respectively, " a kind of novel plastic film leveling roller " and " a kind of novel leveling roller of blow moulding machine ", and the bending rubber that adopts mostly, adjustable bow curved roll, arch rollers, thread roller and waist drum roller etc., basically all be to utilize soft thin material and flatten the geometric curved surfaces that parts contact, soft thin material is subjected in transport process under the effect of geometric curved surfaces, the motion that generation is slided to the both sides span from central authorities' nature is to realize the flattening of soft thin material.This exhibition sliding movement is based on soft thin material and produces with contacting of flattening component geometry curved surface, if it is lower to flatten the smoothness or the cleanliness level of component geometry curved surface, will increase because of the friction coefficient of the not flat spot of part, and have a strong impact on the flattening effect, and, to different types of soft thin material, the parameter that flattens the component geometry curved surface is inequality, the comformability of existing flattening device is all poor especially for the soft thin material of wide format, big with the relative contact that flattens the component geometry curved surface, more be easy to generate physical deformation, and abrade soft thin material surface, cause waste product.

Summary of the invention is the defective that remedies prior art, the utility model proposes a kind of pneumatic traction flattening device, and the technical scheme of employing is as follows respectively:

This pneumatic traction flattening device, be arranged between deflector roll that imports soft thin material and the thread roller of the deriving soft thin material, forming identical flattening parts looking-glass symmetry configuration by two nested structures forms, every cover flattens parts and comprises base, has a pair of pinch under roll and the support thereof gone up that assembly is adjusted in the position, it is characterized in that:

The support of last pinch under roll is separately positioned on the straight line guideway, and this line slideway auxiliary is arranged on one again and has on the hinge of pivot angle adjustment assembly.

Be provided with pinch under roll pressure point adjustment assembly on the line slideway auxiliary, the pressure point of last pinch under roll is adjusted on the cylindrical common tangent of deflector roll that imports soft thin material and the thread roller of deriving soft thin material.

Also be provided with and have the cylinder that the adjustment of inflation pressure assembly provides pinch under roll folding power.

The further feature of this pneumatic traction flattening device is:

It is that assembly is adjusted in the position that a position adjusting accuracy is up to state standards more than 5 grades that assembly is adjusted in the position of last pinch under roll.

Last pinch under roll is the aluminium alloy core tube roller that is coated with antistatic rubber.

The pivot angle of hinge is-10 °～+ 10 °, adjusts according to transport linear velocity, thickness and the tension force of soft thin material.

The pivot angle of hinge adjust assembly comprise adjusting hand wheel, with the conjuncted swing of hinge indicating the pointer of its pivot angle, and with the pivot angle tolerance dish of pointer adapted.

Cylinder is low friction cylinder.

The adjustment of inflation pressure assembly is one to include the pressure regulating valve that air pressure is measured meter.

The bleed pressure of cylinder is 1～4 kg/cm, according to soft thin material transport linear velocity and thickness is adjusted.

The utility model beneficial effect against existing technologies is, flattens the mechanism novelty, structural design optimization, and performance is good, and the precision height flattens effective.The soft thin material that needs to flatten is when transporting at a high speed, be subjected to preestablishing the component effect that the both sides nip rolls of best pivot angle is produced to two side-linings in the process of pinching, to both sides stretching row wrinkle, and it is flattened, do not contact with the geometric curved surfaces that flattens parts, neither be easy to generate physical deformation, its surface can not be scratched again and cause waste product, and, flattening comformability to different types of soft thin material such as plastic sheeting, paper, cloth etc. is strong, especially is suitable for flattening the soft thin material of wide format.
