Abstract
Swelling device in the production of PE film bags, the swelling device includes three fixed transfer rollers being located in rack and three floating transfer rollers positioned at frame lower, three floating transfer rollers are located at the lower section of three fixed transfer rollers, three floating transfer rollers are rotatably arranged on floating shelf, the front end of floating shelf is rotatably arranged on frame lower, the both sides of floating shelf are connected to the lower end of a gas spring, the upper end of gas spring is hinged on upper rack, PE films passed through under the floating transfer roller of front again from the fixation transfer roller of front around passed through under intermediate floating transfer roller again again from intermediate fixation transfer roller around passed through under the floating transfer roller at rear portion again bypassed from the fixation transfer roller at rear portion again after to rear conveying.This swelling device can effectively prevent PE films in the direction of the width pulling force unevenness when occur gauffer influence conveying the problem of.
Description
Technical field
The utility model is related to PE film bag production equipments, the more particularly to swelling device in the production of PE films bag, belong to packaging
Equipment technical field.
Background technology
In the production of PE film bags, need the processes such as feeding, hot weld, shearing that could complete, the PE films in hot weld and shearing
Feed mechanism stops, and feed mechanism, which starts, after completing hot weld, shearing continues to convey backward, so between the feeding on production line is
Progress of having a rest needs energy to ensure that siltation blocking occurs for the smooth and portion of film bag in feeding process in feed mechanism
Enough its is set to keep planarization, tension mechanism common at present under tensioner state in conveying in the device of PE film tensioners automatically
For a dancer, dancer is arranged under PE film pipelines, and PE films are passed through from dancer lower part, and dancer is pressed on PE films, this
Although kind of a mode can realize tensioner, but if in the pulling force unevenness in PE film width directions, PE films in the direction of the width to
Some position is concentrated, and gauffer occurs, and what the conveying power of PE films leaned on is pinch roller, the thickness meeting at the position after the generation of gauffer
It changes, the normal of PE films can be influenced and conveyed backward, it in time can be by pinch roller, after being also resulted in two membranes hot weld
Continuous quality problems eventually lead to the generation of waste product.
Invention content
The above problem existing for swelling device in being produced the purpose of the utility model is to overcome current PE film bags, carries
A kind of swelling device in being produced for PE films bag.
To realize the purpose of this utility model, following technical solutions is used：Swelling device in the production of PE film bags, institute
The swelling device stated include be located at rack on three fixed transfer rollers and three floating transfer rollers positioned at frame lower, described three
Root floating transfer roller is located at the lower section of three fixed transfer rollers, and three floating transfer rollers are rotatably arranged on floating shelf, the front end of floating shelf
It is rotatably arranged on frame lower, the both sides of floating shelf are connected to the lower end of a gas spring, and the upper end of gas spring is hinged on
Upper rack, PE films are passed through under the floating transfer roller of front again from the fixation transfer roller of front around again from intermediate floating transfer roller
Under across again from intermediate fixation transfer roller around passed through under the floating transfer roller at rear portion again again from the fixation transfer roller at rear portion around
Later it conveys backward；Further；The fixed transfer roller of described three is located in a plane, and three fixed transfer rollers are identical, three
Floating transfer roller is located in a plane, and three floating transfer rollers are identical；Further；Between the lower end and rack of the gas spring
It is hinged.
The positive advantageous effects of the utility model are：This swelling device coordinates gas bullet using more floating transfer rollers
Spring, can effectively prevent PE films in the direction of the width pulling force unevenness when occur gauffer influence conveying the problem of, raising can produce
Efficiency and Homes Using TV.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the schematic diagram of floating transfer roller.
Specific implementation mode
In order to more fully explain the implementation of the utility model, the embodiment of the utility model is provided.These implement real
Example is only the elaboration to the utility model, does not limit the scope of the utility model.
In conjunction with attached drawing to the further details of explanation of the utility model, in attached drawing in respectively label for：1：Rack；2:Front
Fixed transfer roller；3：Intermediate fixation transfer roller；4：The fixation transfer roller at rear portion；5:The floating transfer roller of front；6：Intermediate floating transfer roller；
7：The floating transfer roller at rear portion；8：Floating shelf；9：Floating shelf shaft；10：Gas spring；11：PE films；
As shown in the picture, the swelling device in the production of PE films bag, the swelling device include three be located in rack
Fixed transfer roller and three floating transfer rollers positioned at frame lower, three fixing rollers are respectively the fixation transfer roller of front shown in 2,3
Shown in intermediate fixation transfer roller, rear portion shown in 4 fixation transfer roller；Three dancers are respectively the floating of front shown in 5
Transfer roller, floating transfer roller intermediate shown in 6, rear portion shown in 7 floating transfer roller；Three floating transfer rollers are located at three admittedly
Determine the lower section of transfer roller, three floating transfer rollers are rotatably arranged on floating shelf 8, and the front end of floating shelf 8 is rotatably arranged under rack 1
Portion, 9 show floating shelf shaft, and the both sides of floating shelf 8 are connected to the lower end of a gas spring, and the upper end of gas spring is hinged
Hinged between upper rack, the lower end and rack of the gas spring, 10 show gas spring in figure, and PE films are floated from front
It passes through to bypass to pass through under intermediate floating transfer roller again again from the fixation transfer roller of front under turn roller and turn again from intermediate fixation
On roller around passed through under the floating transfer roller at rear portion again bypassed from the fixation transfer roller at rear portion again after to rear conveying；Described three
Fixed transfer roller is located in a plane, and three fixed transfer rollers are identical, and three floating transfer rollers are located in a plane, and three floatings turn
Roller is identical.
In pinch roller feeding backward, floating shelf lifts this tensioner wheel apparatus, and when pinch roller shuts down, floating shelf is fallen
It realizes that expansion tightening wheel, the gas spring of both sides are extended and retracted with rising and falling for floating shelf, feeding process is made steadily to carry out.
After the embodiment that the utility model is described in detail, one of ordinary skilled in the art is clearly understood that,
It does not depart from above-mentioned claim and various change and modification can be carried out under spirit, it is all according to the technical essence of the utility model
To any simple modification, equivalent change and modification made by above example, the range of technical solutions of the utility model is belonged to,
And the utility model is also not only restricted to the embodiment of example in specification.
