Abstract
The invention discloses a strip tensioning device comprising a frame and a crossbeam mounted on the upper portion of the frame. A connecting frame is mounted on the lower portion of the frame. At least two airbags are arranged on the connecting frame. An air inlet is arranged at the bottom of each airbag. Joints extending into the air inlets are mounted on the connecting frame. Nuts used for fastening the airbags sleeve the joints. The joints are connected with air inlet pipes. A press plate is placed on the airbags, and felt is placed on the press plate. An air cylinder is vertically arranged on the crossbeam. A piston rod of the air cylinder penetrates the crossbeam. An upper pillow is mounted at the lower end of the piston rod. The strip tensioning device can meet the requirements on tensioned coiling of thin strips and guarantee strip coiling quality, and is simple in structure, convenient to use, low in production cost and convenient to popularize and use.
Description
Technical field
The present invention relates to a kind of tightening device, particularly relate to a kind of back tension bridle.
Background technology
In band slitting field, thickness of strip scope is increasing at present, and soft or hard state has concurrently.In order to meet the need of market, just building of band to be opened and claimed.Adopt hydraulic pressure to build for middle thick strip and guarantee reeling quality, will there will be following situations if thin strip also adopts hydraulic pressure to build: pressure is too small, and rolling staggered floor degree is large, loose winding; Pressure is excessive, have tear, the phenomenon of broken belt.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, a kind of back tension bridle is provided.This back tension bridle can meet compared with the tensioning of thin strip and batches, and guarantee strip coiling quality, and it is simple in structure, easy to use, productive costs is low, is convenient to promote the use of.
For achieving the above object, the technical solution used in the present invention is: a kind of back tension bridle, it is characterized in that: comprise frame and the crossbeam that is arranged on upper rack, the bottom of described frame is provided with link span, on described link span, be provided with at least two air bags, the bottom of described air bag offers admission port, the joint that stretches into described admission port is installed on described link span, on described joint, cover is useful on the nut of fastening air bag, described joint is connected with air inlet pipe, on described air bag, be placed with pressing plate, on described pressing plate, be placed with felt, on described crossbeam, be vertically provided with cylinder, the piston rod of described cylinder is through crossbeam, and the lower end of described piston rod is provided with upper pillow.
Above-mentioned a kind of back tension bridle, is characterized in that: on described link span, be provided with the air bag mounting hole suitable with described bladder shape.
Above-mentioned a kind of back tension bridle, is characterized in that: on described joint and between joint head and link span, overlap and have pad.
The present invention compared with prior art has the following advantages:
1, of the present invention simple in structure, rationally novel in design, be easy to install.
2, the present invention, by air bag, cylinder, upper pillow and pressing plate are set, by giving airbag aeration, makes to move on air sac belt dynamic pressure plate, give cylinder intake simultaneously, drive upper pillow to move down by cylinder piston rod, thereby band is carried out to tensioning, it is easy to use, and result of use is good.
3, the present invention arranges the air bag mounting hole suitable with bladder shape by being arranged on link span 11, can well locate air bag.
4, of the present invention to realize cost low, and result of use is good, is convenient to promote the use of.
In sum, the present invention is simple in structure, and rationally novel in design, functional reliability is high, and long service life can meet compared with the tensioning of thin strip and batch, and guarantee strip coiling quality, and it is easy to use, productive costs is low, is convenient to promote the use of.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.

The specific embodiment
A kind of back tension bridle as depicted in figs. 1 and 2, comprise frame 3 and the crossbeam 6 that is arranged on frame 3 tops, the bottom of described frame 3 is provided with link span 1, on described link span 1, be provided with at least two air bags 10, the bottom of described air bag 10 offers admission port, the joint 12 that stretches into described admission port is installed on described link span 1, on described joint 12, cover is useful on the nut 13 of fastening air bag 10, described joint 12 is connected with air inlet pipe 2, on described air bag 10, be placed with pressing plate 5, on described pressing plate 5, be placed with felt 4, on described crossbeam 6, be vertically provided with cylinder 7, the piston rod 7-1 of described cylinder 7 is through crossbeam 6, and the lower end of described piston rod 7-1 is provided with upper pillow 8.On described joint 12 and between joint 12 heads and link span 1, overlap and have pad 11.
As shown in Figure 2, on described link span 1, be provided with the air bag mounting hole 11-1 suitable with described air bag 10 shapes.By being set, air bag mounting hole 11-1 can well locate air bag 10.
In the present embodiment, this back tension bridle is by arranging air bag 10, cylinder 7, upper pillow 8 and pressing plate 5, inflate by giving air bag 10, air bag 10 is with on dynamic pressure plate 5 to be moved, give cylinder 7 air inlets simultaneously, drive upper pillow 8 to move down by cylinder 7 piston rod 7-1, thereby band is carried out to tensioning, it is easy to use, and result of use is good.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every any simple modification, change and equivalent structure transformation of above embodiment being done according to the technology of the present invention essence, all still belongs in the protection domain of technical solution of the present invention.
