The internal diameter of cylinder and the outer diameter size of the foamed cotton pipe after grinding are close, so that being obstructed during being inserted in, causes to be inserted in difficulty, because
This time-consuming and laborious, low efficiency by the way of being manually directly inserted in.
Utility model content
For overcome the deficiencies in the prior art, providing a kind of can mitigate being obstructed, mentioning during rubber thin-walled cylinder is inserted in
The rubber thin-walled cylinder of the charging roller of high efficiency is inserted in device.
The utility model uses technical solution below.
A kind of rubber thin-walled cylinder of charging roller is inserted in device, including pedestal, and the pedestal upper end is equipped with circular abutment, institute
It states circular abutment and is sliding combined with top beam, the top beam is fixedly connected by going up and down lock with circular abutment, is set on the top beam
There is vertically disposed hollow tube, the upper port of the hollow tube is equipped with gas-tpe fitting, and the gas-tpe fitting is connected with by tracheae
The lower port of air valve, the hollow tube is equipped with spray head.
Further, the spray head includes cylindrical body and the circle shoulder set on cylindrical body bottom end, in the cylindrical body insertion
In the lower port of blank pipe, the round shoulder resists the lower port of hollow tube, the circumferential surface of the cylindrical body be uniformly provided with four it is vertical recessed
Slot, the perpendicular grooves extend to the middle part of round shoulder from the upper end of cylindrical body, and the upper surface of the round shoulder is equipped with and vertical recessed grain
One end of one-to-one horizontal groove, the horizontal groove is connected to perpendicular grooves, and the other end extends to the circumferential surface of round shoulder.
Further, the bottom end of the spray head is equipped with the type chamber being bonded with charging roll end, the bottom immediately below spray head
Seat upper end is equipped with jig, and the upper end of the jig is equipped with the recessed grain of cone corresponding with type chamber.Type chamber and the recessed grain of cone cooperate
Position-limiting action is risen to charging roller.
The utility model has the following beneficial effects: the compressed air that the utility model is sprayed by spray head is to rubber thin-walled cylinder
Apply expansionary force, extruding force is applied to foamed cotton pipe, reduces rubbing between rubber thin-walled cylinder and foamed cotton pipe during being inserted in
Power is wiped, so that being inserted in more easily, and then improves production efficiency.
