Abstract

A paper manufacturing machinery net portion tensioner comprises a support, a pneumatic tire and a rocker arm. The rocker arm is used for swaying around a support shaft. A bearing seat for supporting a dry net guide rail is fixed to the upper portion of the rocker arm, one end of the pneumatic tire is fixed to the rocker arm, the other end of the pneumatic tire is fixed to the support, the pneumatic tire extends to push the rocker arm to rotate during air inflation, and the direction of the pneumatic tire is opposite to the tension force direction of a dry net, so that the dry net is tensioned. The pneumatic tire is adopted to provide tension fore, the constant tension force effect can be achieved only by adjusting pressure intensity of compressed air, constant tension force control is achieved, and an adjusting function is achieved.

Description

A kind of papermaking equipment wet end stretcher

Technical field

The utility model relates to a kind of tensioning apparatus for the dry net of papermaking equipment, especially for the constant force tensioner of the dry net tensioning of papermaking equipment, and a kind of papermaking equipment wet end stretcher specifically.

Background technology

Dry net stretcher is parts at papermaking equipment wet end, and major function is the dry net of tensioning, and dry net pretension is provided, and makes not to be with the roller of driving to turn round under the pulling force of dry net, makes dry net open smooth simultaneously, is unlikely to produce pleat, and produces paper defects.On low speed paper machine, general dry net is not used constant force tensioner, and existing stretcher generally can produce following deficiency: uncontrollable Tensity size.During electronic or manual stretcher, operating personnel are crawl or manual operation often, carry out by rule of thumb dry net tensioning, when dry net tension, can cause deflector roll bearing load to increase, make deflector roll lifetime, dry net also can be easy to because of overtension wearing and tearing, reduces service life, does while netting pine, can produce pleat, thereby produce paper defects.

In order to overcome the defect of prior art, the utility model provides a kind of constant force tensioner for the dry net tensioning of papermaking equipment, and this device can regulate the tension force of dry net automatically.

Utility model content

For the problems referred to above, the utility model aims to provide a kind of papermaking equipment wet end stretcher.

For realizing this technical purpose, scheme of the present utility model is: a kind of papermaking equipment wet end stretcher, comprises bearing, pneumatic tyre and rocking arm; Described rocking arm is used for shaking around bearing axle; Described rocking arm top is fixed with the bearing block that supports dry net deflector roll; Described pneumatic tyre one end and rocking arm are fixed; The described pneumatic tyre other end and bearing are fixed; Thereby during described pneumatic tyre inflation, extend and promote rocking arm rotation, direction is contrary with dry net direction of pull, thereby strains dry net.

Further, described pneumatic tyre comprises air bag, interior steel ring and end plate, and interior steel ring is fixed on cell edges inboard, and end plate is fixed on cell edges outside, and two clamp cell edges, guarantee the air-tightness of pneumatic tyre.

The utility model constant force tensioner is subject to fabric tension sensor and controller action, and the signal of fabric tension sensor passes to controller, and controller is controlled the interior pressure of pneumatic tyre, thereby it is constant automatically to realize fabric tension.

Beneficial effect

The utility model adopts pneumatic tyre that tension force is provided, because the tension force of pneumatic tyre is determined by compressed-air actuated pressure, as long as regulate compressed air pressure, just can play permanent tension force effect, realize permanent tension force and control, when dry net fluffs or become tight, due to the self-aligning action of pneumatic tyre, also correspondingly elongate or shorten, play regulating action.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

In figure: bearing 1, pneumatic tyre 2, rocking arm 3, deflector roll 4, bearing axle 5.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.

As shown in Figure 1, a kind of papermaking equipment wet end stretcher of the utility model embodiment, comprises bearing 1, pneumatic tyre 2, rocking arm 3; Described rocking arm 3 is used for shaking around bearing axle 5; Described rocking arm 3 tops are fixed with the bearing block that supports dry net deflector roll 4; Described pneumatic tyre 2 one end and rocking arm 3 are fixing; Described pneumatic tyre 2 other ends and bearing 1 are fixing; Thereby extend during described pneumatic tyre 2 inflation, promote rocking arm 3 rotations, direction is contrary with dry net direction of pull, thereby strains dry net.

Further, described pneumatic tyre 2 comprises air bag, interior steel ring and end plate, and interior steel ring is fixed on cell edges inboard, and end plate is fixed on cell edges outside, and two clamp cell edges, guarantee the air-tightness of pneumatic tyre.

The above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any trickle modification that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in the protection domain of technical solutions of the utility model.

Claims
