Abstract
The utility model discloses a winding shaft which comprises an inner core. An air bag is wrapped on the outer side of the inner core. A first tube wall is arranged on the outer side of the air bag and is formed by enclosing of at least two groups of tube petals. Joint positions of all groups of tube petals are connected through telescopic pieces. By adoption of the winding shaft, inner cores of winding materials and a winding barrel can be firmly combined, great convenience is brought to installation and detachment of the inner cores of the winding materials, and working efficiency is improved.
Description
Technical field
The utility model relates to coiler, is specifically related to a kind of spool.
Background technology
Current, coiler is widely used in multiple industry, for example, and cloth coiled strip, plastic sheeting coiled strip, adhesive tape coiled strip and sheet metal coiled strip etc.
Existing coiler all is to provide power by motor, and the motion by transmission shaft drives spool and is rotated, and when executable operations, reel is enclosed within on the spool, finishes coiled strip under the turning effort of spool.
Because current spool all is that fixed diameter is constant, in the coiled strip process, increasing gradually of material the loosening phenomenon of coiled strip can occur, simultaneously, because the reel of coiled strip is different with roll size, can there be the reel shaking phenomenon, or has the problem of loading and unloading difficulty, directly have influence on the rolling of product or the operation of next procedure, influence product design, also reduced work efficiency simultaneously.
The utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of spool, realize that reel and the spool of coiled strip can be fixed, for convenience detach, improved work efficiency.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of spool, it comprises inner core, and the described inner core outside is enclosed with air bag, and the described air bag outside is provided with tube wall one, and around forming, each junction of organizing described pipe lobe is connected by extensible member described tube wall one by at least two group pipe lobes.
Preferably, described tube wall one outside is arranged with tube wall two, and described tube wall two is centered on by at least two group pipe lobes and forms.
Preferably, the junction of the pipe lobe of the junction of the pipe lobe of described tube wall one and described tube wall two is crisscross arranged.
Preferably, described tube wall one is centered on by three groups of pipe lobes and forms.
Preferably, described tube wall two is centered on by three groups of pipe lobes and forms.
Preferably, also be provided with vent plug on the diametric plane of described inner core, described vent plug is connected with described air bag.
Preferably, described extensible member is spring.
Pass through technique scheme, spool disclosed in the utility model, it is its form that is set to the inflatable convergent-divergent, expansion or contraction by two-layer tube wall on the spool, the reel of coiled strip can be set on this spool securely, not be moved, simultaneously, also make things convenient for the loading and unloading of reel, improved work efficiency.
Description of drawings
Fig. 1 is the schematic cross-section of the disclosed a kind of spool of the utility model embodiment;
Fig. 2 is the structural representation of the disclosed spool of the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
Referring to Fig. 1 and Fig. 2, comprise inner core 11, inner core 11 outsides are enclosed with air bag 12, and air bag 12 outsides are provided with tube wall 1, and tube wall 1, is connected by spring 15 between every group of pipe lobe around forming by three groups of pipe lobes 14.
The outside of tube wall one is provided with tube wall 2 16, and tube wall 2 16 also is to be centered on by three groups of pipe lobes 14 to form, and is connected by spring 15 between the pipe lobe.The pipe lobe junction of the pipe lobe junction of tube wall 1 and tube wall 2 16 is crisscross arranged, and air bag can be wrapped like this, can not be exposed to the junction of pipe lobe, prevents the air bag breakage.
The diametric plane place of volume core also is provided with vent plug 17, and vent plug 17 directly is connected with air bag.Use air pump that vent plug 17 is inflated, make air bag 12 inflations, the spring 15 that drives each pipe lobe junction of tube wall 1 is upheld, thereby the internal diameter of tube wall 1 enlarges, the internal diameter that drives tube wall 2 16 simultaneously enlarges, when making the internal diameter of outer wall draw together to a certain degree according to actual needs, just stop air bag 12 inflations.
In real work, the spool under the initial condition is in contraction state, and the reel of coiled strip is enclosed within on this spool, by air pump vent plug 17 is inflated then, spool enlarges gradually, makes reel be enclosed within on the spool securely, be not moved, behind the end-of-job, unplug the gas match, gas is emitted, spring on tube wall one and the tube wall two shrinks, make reel get back to initial condition, with convenient dismounting to reel, realize blanking.
This spool is used on the coiler, can cooperate motor to use, under the drive of motor, be rotated rolling, because this spool is set to the form of inflatable convergent-divergent, by expansion or the contraction of spool, reel can be set on the spool securely, be not moved, make things convenient for the loading and unloading of reel, improved work efficiency.
Claims (7)
1. a spool is characterized in that, comprises inner core, and the described inner core outside is enclosed with air bag, and the described air bag outside is provided with tube wall one, and around forming, each junction of organizing described pipe lobe is connected by extensible member described tube wall one by at least two group pipe lobes.
2. a kind of spool according to claim 1 is characterized in that, described tube wall one outside is arranged with tube wall two, and described tube wall two is centered on by at least two group pipe lobes and forms.
