Description
Technical field
The utility model is related to cutting machine technical field, especially a kind of gas expansion shaft buffer gear.
Background technology
Cutting machine is that the big various thin materials such as paper, film, non-woven fabrics, aluminium foil, mica tape of rolling up are cut into different width
Equipment before the print of degree rouleau, after print, is usually used in papermaking equipment and printing packaging machinery, is frequently necessary to use gas expansion shaft in cutting machine
Volume to do coiled strip material send operation.Gas expansion shaft can cause serious bias when harmomegathus is inflated between gas expansion shaft and sleeve pipe, therefore
Also can be seriously eccentric during cutting product, cause tension fluctuation very big, coiled strip material is neglected pine and neglects tight, causes product staggered floor serious, frequent
The problems such as broken belt, gas expansion shaft deformation, bearing life shorten.Therefore need buffer gear to reduce the eccentric degree of gas expansion shaft, carry
The efficiency of cutting machine high and the qualification rate of product.
Utility model content
The technical problems to be solved in the utility model is：In order to solve gas expansion shaft when harmomegathus is inflated, gas expansion shaft and sleeve pipe
Between can cause serious bias, also can seriously bias, the problem for causing tension fluctuation very big, there is provided a kind of gas rises during cutting product
Axle buffer gear.
The utility model solves the technical scheme that its technical problem used：A kind of gas expansion shaft buffer gear, including bottom
Seat, support bar and buffer spring, the post upper are connected with locating piece, and the locating piece upper surface offers rises for gas
The locating slot of axle two ends positioning, the two ends of gas expansion shaft are fastened in locating slot, and pilot hole, the support bar are provided with the base
It is arranged in pilot hole, the buffer spring is set in outside support bar, the buffer spring is supported between base and locating piece,
When gas expansion shaft is installed, the two ends of gas expansion shaft are placed in the locating slot of locating piece, because the lower section of locating piece is by buffer spring
Support, when gas expansion shaft is inflated, buffer spring can reduce the eccentric degree of gas expansion shaft and sleeve pipe, prevent from cutting eccentric during product, guarantor
Hold even tension, it is to avoid the problems such as causing serious product staggered floor, frequent broken belt, gas expansion shaft deformation, bearing life to shorten.
Further, be threaded with adjusting nut on the support bar, the adjusting nut away from the base one
End is provided with platform, and the buffer spring is located between the platform and locating piece.
The beneficial effects of the utility model are that the utility model sets buffer unit, gas expansion shaft inflation at gas expansion shaft two ends
When, buffer spring can reduce the eccentric degree of gas expansion shaft and sleeve pipe, prevent from cutting eccentric during product, holding even tension, it is to avoid
The problems such as causing serious product staggered floor, frequent broken belt, gas expansion shaft deformation, bearing life to shorten.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the front view of the utility model embodiment 1；
Fig. 2 is the left view of the utility model embodiment 1.
Fig. 3 is the front view of the utility model embodiment 2
In figure：1st, gas expansion shaft, 2, base, 3, support bar, 4, buffer spring, 5, locating piece, 6, adjusting nut, 601, flat
Platform.
Specific embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Basic structure of the present utility model is only illustrated in a schematic way, therefore it only shows the composition relevant with the utility model.
Embodiment 1
As illustrated in fig. 1 and 2, a kind of gas expansion shaft buffer gear, including base 2, support bar 3 and buffer spring 4, the support
The upper end of bar 3 is connected with locating piece 5, and the upper surface of the locating piece 5 offers the locating slot for the two ends of gas expansion shaft 1 positioning, and gas rises
The two ends of axle 1 are fastened in locating slot, and pilot hole is provided with the base 2, and the support bar 3 is arranged in pilot hole, described
Buffer spring 4 is set in outside support bar 3, and the buffer spring 4 is supported between base 2 and locating piece 5, when gas expansion shaft 1 is installed,
The two ends of gas expansion shaft 1 are placed in the locating slot of locating piece 5, because the lower section of locating piece 5 is supported by buffer spring 4, gas rises
When axle 1 is inflated, buffer spring 4 can reduce the eccentric degree of gas expansion shaft 1 and sleeve pipe, prevent from cutting eccentric during product, holding tension force
Uniformly, it is to avoid cause the problems such as serious product staggered floor, frequent broken belt, gas expansion shaft 1 deform, bearing life shortens.
Embodiment 2
As shown in figure 3, embodiment 2 is with the difference of embodiment 1：Adjusting nut is threaded with the support bar 3
6, the adjusting nut 6 is provided with platform 601 away from one end of the base 2, and the buffer spring 4 is located at the platform 601
Between locating piece 5.
In the present embodiment can according to the eccentric degree of gas expansion shaft 1 and sleeve pipe, rotate adjusting nut 6 to locating piece 5 near or
Away from adjusting the elastic force of buffer spring 4 with this so that buffer spring 4 reaches best buffering effect；In addition as use is buffered
The elastic force of spring 4 can slowly diminish, now in order to avoid changing the waste that buffer spring 4 is caused, on rotatable adjusting nut 4
Move so that the elastic force of buffer spring 4 becomes big.
With above-mentioned according to desirable embodiment of the present utility model as enlightenment, by above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this utility model technological thought completely.This reality
The content on specification is not limited to new technical scope, it is necessary to its technology is determined according to right
Property scope.
