Enter to carry the screw of spanner, the installation of both sides nylon jacket be major part outwardly, microcephaly is inwardly.Last both sides are manually tightened together pulls
Hand, is fixed for the cardboard tube of overlay film volume.The installation weight is big, high to cardboard tube intensity requirement, needs two people same during installation
When coordinated, while need very great strength can fix, using terminate dismantle when, taper nylon jacket be not easy take out, very
It is inconvenient.
Utility model content
The purpose of this utility model is a kind of easily assembling cardboard tube fixing device rolled up for overlay film of offer, and it has
It is simple in construction and the characteristics of be easy to handling, to solve above-mentioned to ask present in overlay film volume cardboard tube fixation procedure in the prior art
Topic.
For up to this purpose, the utility model uses following technical scheme：
A kind of easily assembling cardboard tube fixing device rolled up for overlay film, it includes main cylinder, the two ends of the main cylinder
Connecting portion is provided with, wherein, offer and be movably disposed in several through holes, the through hole on the outer wall of the main cylinder
Have to be provided with medium runner, the medium runner in tightening piece, the main cylinder and be passed through flow media, coordinate tightening piece in institute
State and expansion valve be provided with main cylinder, the expansion valve is connected with the medium runner, the valve element of the expansion valve with it is described
Tightening piece is connected, and the two ends of the main cylinder are correspondingly arranged on the medium being connected with the medium runner and enter control valve and Jie
Matter discharges control valve.
Especially, the radius of the connecting portion is less than the radius of the main cylinder, and is provided with bearing thereon.
Especially, the medium is any of gas or liquid.
Especially, the through hole is strip, offers 12, and every four are distributed in for one group, every group of four through holes
On the same circumference of the main cylinder.
Especially, the outer wall of the tightening piece is the circular arc for coordinating the main cylinder outer wall.
The beneficial effects of the utility model are, described compared with prior art to consolidate for the easily assembling cardboard tube that overlay film is rolled up
Determine device and the fixation and dismounting to cardboard tube are realized by the flexible of tightening piece, be not only simple in structure, it is ingenious in design；And
It is easy to handling, it is time saving and energy saving, improve production efficiency.
Brief description of the drawings
Fig. 1 is the easily assembling cardboard tube fixing device rolled up for overlay film that the utility model embodiment 1 is provided
Structural representation.
Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1, Fig. 1 is that the easily assembling for being used for overlay film volume that the utility model embodiment 1 is provided is hard
The structural representation of cardboard tube fixing device.
It is a kind of to include main cylinder 1, the main cylinder for the easily assembling cardboard tube fixing device that overlay film is rolled up in the present embodiment
The two ends of body 1 are provided with connecting portion 2, and the radius of the connecting portion 2 is less than the radius of the main cylinder 1, and is provided with thereon
Bearing 3.12 through holes 4 are offered on the outer wall of the main cylinder 1, the through hole 4 is the strip along the length direction of main cylinder 1
Hole, every four are distributed on the same circumference of the main cylinder 1 totally for one group, three groups, every group of four through holes 4.The through hole 4
Inside it is movably disposed within tightening piece 5, the main cylinder 1 being provided with gas flow 6, the gas flow 6 and is passed through compression
Air, coordinates tightening piece 5 in being provided with gas expansion valve 7 in the main cylinder 1, the gas expansion valve 7 and the gas stream
Road 6 is connected, and the valve element 8 of the gas flow 6 is connected with the tightening piece 5, in the outside of the bearing 3 on the connecting portion
Charge valve 9 and air bleeding valve 10 are installed, the charge valve 9 and air bleeding valve 10 are connected with the gas flow 6.
The outer wall of the tightening piece 5 is the circular arc for coordinating the outer wall of main cylinder 1.
In use, first main cylinder 1 is penetrated in cardboard tube, open charge valve 9 and compression sky is passed through into gas flow 6
Gas, compressed air enters each gas expansion valve 7, promotes the valve element 8 of gas expansion valve 7 to be displaced outwardly, and then drives tightening piece 5
It is displaced outwardly holding out against the inwall of cardboard tube, that is, plays fixed overlay film volume cardboard tube；, only need to the row of opening during using finishing dismounting
Air valve 10, the compressed air in gas flow 6 is discharged, and the return of valve element 8 drives tightening piece 5 to move inward, with cardboard tube
Inwall is separated, you can complete dismounting.
Above example is to elaborate general principle of the present utility model and characteristic, and the utility model is not by above-mentioned example
Limitation, on the premise of the utility model spirit and scope are not departed from, the utility model also has various change and change, these changes
Change and change and both fall within the range of claimed the utility model.Scope is claimed in the utility model will by appended right
Ask book and its equivalent thereof.
