The utility model provides a following technical scheme: the utility model provides a but quick assembly disassembly's of rolling equipment inflatable shaft, includes axis body and connecting seat, the equipartition has a plurality of mounting hole on the connecting seat, and each mounting hole is equipped with the spacing protruding muscle that extends towards the mounting hole middle part including the screw portion of entering and the spacing portion of screw that switches on with the screw portion of entering respectively, the bottom department of the inner wall of the spacing portion of mounting hole position screw, and the space between spacing protruding muscle and the spacing portion top of screw is spacing space. Adopt above-mentioned technical scheme, but provide a quick assembly disassembly's of rolling equipment physiosis axle of easy dismounting, simple structure.
Description
Technical Field
The utility model relates to a rolling equipment, in particular to but quick assembly disassembly's of rolling equipment inflatable shaft.
Background
The supermarket cash register paper and label paper are automatically rolled through rolling equipment, and the equipment mainly comprises a feeding device, a rolling device, a cutting device, a paper feeding tube core device, a rolling device, a labeling device and a finished product output device.
The rolling device is a rotatable turntable, and a plurality of air expansion shafts for rolling are uniformly distributed on the turntable along the circumference in the reverse direction.
The existing air expansion shaft mainly comprises a shaft body and a connecting seat, and the connecting seat is provided with a plurality of screw holes for mounting screws.
In the dismouting in-process, need set up the screw hole that corresponds with the screw on the connecting seat in advance on the carousel, then correspond the connecting seat of inflatable shaft with the screw hole on the carousel, install the screw at last. The process can be completed only by matching two operators, and the process is time-consuming and complex in disassembly and assembly structure.
Disclosure of Invention
Not enough to prior art exists, the utility model provides a but quick assembly disassembly's of easy dismounting, simple structure's rolling equipment inflatable shaft.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a but rolling equipment's quick assembly disassembly's inflatable shaft, includes axis body and connecting seat, its characterized in that: the connecting seat on the equipartition have a plurality of mounting hole, each mounting hole is equipped with the spacing protruding muscle that extends towards the mounting hole middle part including the screw portion of acceping and the spacing portion of screw that switches on with the screw portion of acceping respectively, the bottom department of the inner wall that the mounting hole is located the spacing portion of screw is equipped with spacing protruding muscle, the space between spacing protruding muscle and the spacing portion top of screw is spacing space.
The cross section of each mounting hole is oval.
By adopting the technical scheme, the connecting seat of the air expansion shaft is inserted into the corresponding screw head part through the screw inlet part on the connecting seat, after the screw head part completely enters the screw inlet part, the connecting seat is rotated to enable the screw to enter the screw limiting part, the head of the screw is positioned in the limiting space at the moment, and the screw rod is positioned in the space of the limiting convex rib to realize quick installation. On the contrary, if the air expansion shaft needs to be disassembled, the selection and the grabbing in the direction opposite to the installation direction enable the head of the screw to be located at the screw inlet part, and therefore the connecting seat and the screw can be disassembled. Not only is the dismounting convenient and time-saving, but also the structure is simple.
The present invention will be further described with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic perspective view of an embodiment of the present invention;
fig. 2 is a schematic view of an installation state of the embodiment of the present invention.
Detailed Description
As shown in fig. 1 and 2, the quick detachable air expansion shaft of the winding device includes a shaft body 1 and a connecting seat 2, the connecting seat 2 and the shaft body 1 can be integrally formed or separately arranged, and the connection is implemented by welding or riveting after being respectively formed. The equipartition has a plurality of mounting hole 3 on the connecting seat 2, and each mounting hole 3 is equipped with spacing protruding muscle 321 towards 3 middle parts of mounting hole extension including screw entering portion 31 and the spacing portion 32 of screw that switches on with screw entering portion 31 respectively, the bottom department that mounting hole 3 is located the inner wall of the spacing portion 32 of screw, and the space between spacing protruding muscle 321 and the spacing portion 32 top of screw is spacing space 322. The connecting seat 2 of the air expansion shaft is inserted into the corresponding screw head part through the screw inlet part 31 on the air expansion shaft, after the screw head part completely enters the screw inlet part 31, the connecting seat 2 is rotated to enable the screw to enter the screw limiting part 32, the head part of the screw is positioned in the limiting space 322 at the moment, and the screw rod is positioned in the space of the limiting convex rib 321 to realize quick installation. Conversely, if the air expansion shaft needs to be disassembled, the connecting seat 2 and the screw can be disassembled by rotating the air expansion shaft in the direction opposite to the installation direction and enabling the head of the screw to be located at the screw inlet part 31. Not only is the dismounting convenient and time-saving, but also the structure is simple.
The cross section of the mounting hole 3 in the embodiment of the present invention is oval, and of course, can be determined according to the shape of the screw, and can also be rectangular. It should be noted that the screw 42 may be attached to the turntable 4 in advance, or the screw attachment base 41 may be attached to the turntable 4, and then the screw 42 may be attached to the screw attachment base 41.
