Abstract
The utility model aims to provide an air expansion shaft, which has a simple structure, can tightly cooperate with other devices and can improve the whole production efficiency. In order to achieve the aim, the technical scheme is the air expansion shaft. The air expansion shaft comprises a metal casing. A rubber inner sleeve is disposed in the metal casing. The metal casing is provided with a plurality of hollow grooves, and one side of the metal casing is provided with an air hole. With the adoption of the above technical scheme, the air expansion shaft is advantageous in that the air hole is inflated, the rubber inner sleeve is expanded, and the rubber inner sleeve extends out from the hollow groove, forming a projection, and thereby a paper roll sleeving the projection can be effectively clamped.
Description
Technical field
The utility model relates to the manufacturing technology of aluminum foil and adhesive tape, relates in particular to the gas expansion shaft that is adopted in its technology.
Background technology
Gas expansion shaft is a kind of purpose made rolling, unreeling shaft, can expand through high-pressure aerated back surface portion, and the venting back surface portion axle of withdrawal rapidly is called inflatable axle, airpressure axle, main axis of dilatation, flatulence axle, inflatable roller, inflation axle, pressure axis etc.Inflatable axle, inflatable are overlapped extremely easy to use, quick; Only need the user to provide source of the gas for oneself; Air-pressure controlling is in the 6-8kg scope, when needing the locking reel core, as long as air gun just can be accomplished facing to the inflation of the valve on the inflatable axle; In the time of need loosening the reel core discharging, promptly exit with the slip gaseous core that hand is pressed on the valve.It still is not enough hommization that but such structure directly is used for the aluminum foil and adhesive tape manufacturing line, so we need make improvements, and makes it more be applicable to specific unreeling machine.
The utility model content
The purpose of the utility model provides gas expansion shaft, and is simple in structure, using and can closely cooperating with other equipment, improves production efficient.
In order to reach said purpose, the technical scheme that the utility model adopted is a gas expansion shaft, comprises betal can, and cover in the rubber is housed in the betal can, has a plurality of dead slots on the said betal can, and betal can one side has pore.
Preferably, also be provided with the venting valve on the said pore.The venting valve is compared with slip gaseous core of the prior art, and is more durable, and avoids because maloperation causes exitting at work and causes the generation of accident.
Preferably, said betal can is provided with slide calliper rule.Such structure makes things convenient for the location after paper roll is installed first, also helps detecting the length of paper roll in addition, avoids putting into the paper roll that falls short of specifications.
Owing to adopted said technical scheme, the utility model gas expansion shaft is through putting on the air to pore, makes cover bulging in the rubber, and cover leans out from dead slot in the rubber, forms protrudingly, just can effectively block socket paper roll above that.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the utility model gas expansion shaft overall system structure scheme drawing.
Fig. 2 is the constructional drawing of cover in the utility model rubber.
The specific embodiment
As shown in Figure 1, gas expansion shaft comprises betal can 1, and cover 2 in the rubber is housed in the betal can 1, has a plurality of dead slots 3 on the said betal can 1, and betal can 1 one sides have pore 4.Also be provided with venting valve 5 on the said pore 4.Said betal can 1 is provided with slide calliper rule 6.
When volume dress be as long as receive the paper roll cover on the gas expansion shaft, then through pore 4 is put on the air, makes cover 2 bulging in the rubber, and cover 2 leans out from dead slot 3 in the rubber, forms convexity, just can effectively block the paper roll that is socketed on the betal can 1.Also be provided with venting valve 5 on the said pore 4, avoid when rotating, opening pore 4 and cause paper roll to get loose.Whether simultaneously whether said betal can 1 is provided with slide calliper rule 6 and not only can detects and observe paper roll and place correctly, and can also meet the requirements by the test paper volume specification.
Through such structure, the present invention further improves gas expansion shaft, makes it more be applicable to the manufacturing technology of aluminum foil and adhesive tape.
The above is merely the specific embodiment of the utility model; But the architectural feature of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
