Specific embodiment:
In order to keep the above objects, features and advantages of the present invention more obvious and easy to understand, with reference to the accompanying drawing to this hair
Bright specific embodiment is described in detail.
As shown in Figure 1-3, a kind of cloth winding up roller of textile printing and dyeing finishing phase comprising main axis of dilatation and setting are swollen
Reel 111 on the outside of swelling shaft, main axis of dilatation include cylindrical axis body, plunger 104, reset spring 106, expansion pin retainer and multiple
Expansion pin 110, cylindrical axis body include shaft body inner surface, axis body outer surface, and the left and right ends of cylindrical axis body are respectively formed with
First axle end opening 116 and the second shaft end opening, first axle end opening 116 are open with the second shaft end and are connected to by hollow axocoel;
Multiple body openings are provided on cylindrical axis body, plunger 104 is cylinder, and plunger includes having plunger first end 121, plunger
The piston body of second end 123, piston body have outer plunger surface, and piston body includes the length point along outer plunger surface
Multiple protrusions of cloth and multiple recess;Main axis of dilatation further includes first handle and second handle, wherein first handle and second handle
Structure is identical, includes handle chassis and handle actuator, and first handle immovably one end with cylindrical axis body
The handle actuator of connection, first handle is prominent from first axle end opening 116;Second handle is immovable with piston body
One end is connected, and second handle rotation rotates piston body;The second handle immovably other end with cylindrical axis body
It is connected, so that the handle actuator of second handle is from the open-ended protrusion of the second axis, and piston body is made to be located at cylinder
In shape axis body, return spring 106 is located between the handle base of first handle and the end of piston body;Cylindrical axis body includes
The gas chamber 150 being located on the opposite end of main axis of dilatation is provided with reset spring 106 in gas chamber 150, also sets up on cylindrical axis body
There is the air inlet 152 for air pressure to be introduced to gas chamber 150, wherein air inlet 152 is hermetically connected to gas chamber 150.
When first handle and second handle are immovably connect with cylindrical axis body, piston body is located in hollow shaft
It is intracavitary, so that multiple protrusions are aligned with multiple body openings.
Multiple body openings are provided with multirow, and multirow body openings are distributed along the length and perimeter of cylindrical axis body, and
Extend along the longitudinal axis of cylindrical axis body.
Piston body has plungers length, the first diameter of plunger, the second diameter of plunger, wherein the first diameter of plunger is more
The diameter of the plunger body of a raised position, the second diameter of plunger are the diameters of the plunger body of multiple recessed positions.
Each of multiple expansion pins 110 include plunger and pin main body, and expansion pin retainer includes along expansion pin
Multiple pins opening of retainer distribution.
The size of multiple pin openings is equal to the shank size of expansion pin 110, and plunger size is greater than the size of pin opening, to permit
Perhaps expansion pin 110 is located in pin opening and plunger is not passed through pin opening.
Expansion pin 110 is located in pin opening, and to be located at hollow shaft intracavitary for expansion pin retainer, so that multiple expansion pins
110 shank is prominent from multiple body openings, so that plunger is aligned with multiple protrusions, so that multiple protrusions are protruded outward in plunger
On, the pin main body of multiple expansion pins 110 is prominent from multiple body openings.
When main axis of dilatation is located in the cavity of reel 111, multiple shanks are protruded outward to be pressed against the inner wall of reel 111, will
Main axis of dilatation 100 is movably associated with reel 111.
In order to remove main axis of dilatation 100 from the cavity of reel 111, actuator handle is moved along the longitudinal axis of main axis of dilatation,
So that multiple recess are aligned with multiple body openings, plunger is allowed to be moved into multiple recess, so that they are no longer press against volume
The inner wall of cylinder 111, main axis of dilatation 100 can take out from reel 111.
Gas chamber 150 is associated with plunger first end 121, so that making a reservation for when the air pressure in gas chamber 150 is equal to or higher than
When horizontal, gas chamber 150 pushes plunger first end 112, so that plunger 104 is moved along the direction that plungers length extends.This makes
It obtains plunger 104 and is located so that multiple protrusions are aligned with expansion pin 110, and 123 compression reseting spring 106 of plunger second end.
When the air pressure in gas chamber 150 is lower than predeterminated level, gas chamber 150 is pushed against plunger first end 121.Therefore, bullet is resetted
Spring 106 compresses, so that plunger 104 moves in the opposite direction along the axis extended along plungers length.This makes plunger 104 fixed
Position is retracted into hollow axocoel at multiple recess are directed at expansion pin 110 to allow to clamp pin.
The embodiment is to be illustrated the present invention, and is not intended to limit the present invention.Anyone skilled in the art
Without departing from the spirit and scope of the present invention, it modifies to the embodiment, therefore rights protection model of the invention
It encloses, should be as listed in the claims of the present invention.
