Embodiment:
As shown in attached drawing 1 to attached drawing 8: a kind of limit of packaging material during the packaging process turns limiting device, including mounting plate
1, rolling bearing 101, rotating cylinder 2, rake tooth 201, limit rotary device 3, triangle switch block 301, fixture block 302, diving board 303, limit moving device
4, limited block 401, blend stop 402, fixed block 5, stubborn block 501, around block 502, inserted block 503 and lifting the ball 504;It is offered on mounting plate 1
Blind hole at one;101 outer circle of rolling bearing is by being interference fitted into the blind hole of mounting plate 1;Rotating cylinder 2 is stepped cylindrical structure, is used
In suit packaging material, bottom cylinder is by being interference fitted into 101 inner circle of rolling bearing;Rake tooth 201 is triangular prism structure,
It shares everywhere, circularizes and be distributed in 2 outer circle of rotating cylinder;Limit rotary device 3 is made of triangle switch block 301, fixture block 302, diving board 303,
It shares everywhere, circularizes and be distributed in the top side face of mounting plate 1;Moving device 4 is limited by 402 two parts group of limited block 401 and blend stop
At sharing at three, circularize and be distributed in 2 top side face of rotating cylinder;Limited block 401 is rectangular block, is fixed in 2 top side face of rotating cylinder;
Fixed block 5 is by twisting block 501, and around block 502, inserted block 503 and lifting the ball 504 are formed, and is set to 2 top side face the center point of rotating cylinder, corresponding rotating cylinder 2
Position offers downwards ladder sky, and the first ladder is delthyrium, and bottom outlet is cylindrical hole;Block 501 is twisted for cylinder, on outer circle circumference
Offer the groove of annular spread at three.
Wherein, triangle switch block 301 is triangular prism structure, is connected on mounting plate 1 by pin shaft, can do diameter around pin shaft axis
To movement, fillet is excessive at one jiao of pin shaft fixation, and when rotating cylinder 2 rotates clockwise, rake tooth 201 can be by triangle switch block 301
It pushes aside, in rotation counterclockwise, then rake tooth 201 can be stopped by triangle switch block 301, and then rotating cylinder 2 is made to stop operating.
Wherein, fixture block 302 is rectangular strip structure, and four rounding of angle, top offers dovetail groove at one, is connected by screw to solid
Due in 1 top side face of mounting plate, the trapezoidal side of left and right ends limits the rotational angle of triangle switch block 301.
Wherein, diving board 303 is rectangular slab at one, is fixed on fixture block 302 by spring at two, when 301 turns of triangle switch block
It when moving at this, can be rotated backward by elastic force, make the right angle of its right end always in the slewing area of rake tooth 201, make to turn
Cylinder 2 can be by the blocking of triangle switch block 301 when inverting.
Wherein, blend stop 402 is strip, and both ends rounding is connected in 2 top side face of rotating cylinder by pin shaft, can be around pin shaft
Axis does radial motion, is connected on limited block 401 on bottom side by spring, is connected to fixed block by drawstring on upper side
On 5, under the pulling force by 401 upper spring of limited block, blend stop 402 stretches out the outer circle of rotating cylinder 2, thin on rotating cylinder 2 to being attached to
Film roll, which is formed, to be stopped, and prevents its generation from moving radially.
Wherein, it is triangular prism structure around block 502, is set to and twists 501 bottom side of block, three faces is equipped with arc groove, and three angles
Place offers circular hole, and there is drawstring in system in hole, and when rotating fixed block 5, drawstring is wound on arc groove.
Wherein, inserted block 503 is corner block, is set to around 502 bottom side of block, radial motion will not be generated, by 5 turns of fixed block
It moves after packing up blend stop 402, is inserted into the stepped hole of 2 top surface of rotating cylinder.
Wherein, lifting the ball 504 is ball with holes, is set in inserted block 503, the stepped hole bottom on rotating cylinder 2 is connected to by spring
On end, when fixed block 5 is pulled upwardly, receive the pulling force of spring, only can pull-up certain altitude, meet the rotation need of fixed block 5
Ask, and lifting the ball 504 in the hole of inserted block 503 with the hole linear contact, by fixed block 5 rotation influenced, will not be with its turn
It is dynamic.
The specifically used mode and effect of the present embodiment:
In the present invention, when use, first pulls out fixed block 5 and rotates a few, and blend stop 402 is pulled to rotate, when 402 end of blend stop into
When entering within 2 outer circle range of rotating cylinder, film roll installation is set on rotating cylinder 2, then stir fixed block 5 outward and reversely rotate,
The pulling force that blend stop 402 receives 401 upper spring of limited block is swung out, and end is stretched out other than 2 outer circle of rotating cylinder, is formed at three and is stopped,
Prevent film roll from generating axial movement, and when rotating cylinder 2 rotates clockwise, the longest bevel edge of rake tooth 201 stirs triangle switch block
301, and when rotating cylinder 2 generates rotation counterclockwise, the right-angle side of rake tooth 201 stirs the longest bevel edge of triangle switch block 301, triangle
Switch block 301 is rotated clockwise around pin shaft, and the blocking by 302 upper trapezoid bevel edge of fixture block, is stopped operating, and rotating cylinder 2 stops at this time
Rotation, does not continue to rotate counterclockwise, fixed block 5 can rotate counterclockwise clockwise when in use, can form blend stop 402
Pulling force, the configuration of the present invention is simple, limit rotary device 3 are automatic trigger without operation, and limit moving device 4 is only in installing and dismounting film roll
It needs to operate, operation only needs to rotate fixed block 5, easy to operate.
The embodiment of the present invention is given for the purpose of illustration and description, and is not exhaustively or by this to send out
It is bright to be limited to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.Choosing
Selecting and describe embodiment is and to make those skilled in the art to more preferably illustrate the principle of the present invention and practical application
It will be appreciated that the present invention is to design various embodiments suitable for specific applications with various modifications.
