As a further technical scheme of the utility model, the bottom edge of main shaft cover plate forms fixed connection structure through bolt and main shaft.

As the utility model discloses further technical scheme, tight key and through-hole looks adaptation expand, symmetrical pressure spring is installed at the outside both ends of extension board.

As a further technical scheme of the utility model, the centre of a circle department of main shaft cover plate is provided with the charging connector that is linked together with the gasbag.

As a further technical scheme of the utility model, inflatable joint and charging connector looks adaptation.

Advantageous effects

The utility model provides an automatic tight mechanism that expands of label feed. Compared with the prior art, the method has the following beneficial effects:

the utility model provides an automatic tight mechanism that expands of label feed, through the mode that adopts the gas pressure mode to expand the tight material of book and roll up, not only can eliminate the problem that the material was rolled up and is slipped for the feed is stable, and in addition after the gasbag gassing, the material is rolled up and also can easily be put and get, thereby has improved the practicality of use.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution of an automatic expansion mechanism for label feeding: the utility model provides an automatic tight mechanism that expands of label feed, includes material book 1, bloated tight subassembly 2 and inflation joint 3, and material book 1 cover is established in the outside of bloated tight subassembly 2, and inflation joint 3 and charging connector 211 looks adaptation, inflation joint 3 connect compressed air.

Referring to fig. 2-3, the expansion assembly 2 includes a material roll tray 21, a spindle 22 is installed on the top of the material roll tray 21, an air bag 23 penetrates through the spindle 22, the top of the air bag 23 is connected with a spindle cover plate 25 through an air bag clamp 24, the bottom edge of the spindle cover plate 25 forms a fixed connection structure with the spindle 22 through bolts, a plurality of groups of through holes 26 distributed in a circumferential shape at equal intervals are formed in the side surface of the air bag 23, a plurality of groups of support plates 27 corresponding to the through holes 26 are installed on the outer side surface of the air bag 23, an expansion key 28 is installed on the outer side of each support plate 27, the expansion key 28 penetrates through the through holes 26 and is connected with expansion tiles 29, the expansion key 28 is matched with the through holes 26, symmetrical compression springs 210 are installed at two ends of the outer side of each support plate 27, an inflation material roll nozzle 211 communicated with the air bag 23 is arranged at the center of the spindle cover plate 25, and the diameter of the spindle 22 is smaller than the inner diameter of the spindle 1.

The utility model discloses a theory of operation: when the device is used, the inflating nozzle 211 is pressed to exhaust the air bag 23, the expansion key 28 can drive the expansion tiles 29 to contract inwards and is smaller than the inner diameter of the material coil 1, at the moment, the material coil 1 can be easily put in or taken out, if the material coil 1 is put in, the inflation connector 3 connected with compressed air can be used for pressing the inflating nozzle 211 after the material coil 1 is put in, the compressed air is filled in the air bag 23, and along with the expansion of the air bag 23, the expansion key 28 can push the expansion tiles 29 to expand all around until the material coil 1 is jacked, so that the non-slip effect can be achieved.
