Oppositely oriented II 3-3 of direction rotation axis of bag on roll is torn, while preventing connecting cylinder 3-2 from rotating with hand, utilizes screw nut driving
Principle, connecting cylinder 3-2 can be separated from II 3-3 of bumping post 3-1-1 and axis quickly, convenient for quick-replaceable it is coiled company volume
Bag.Embodiment ten:
Illustrate that present embodiment, present embodiment are below with reference to Fig. 1,2,3,4,5,6,7,8,9,10,11,12,13,14
Further explanation to embodiment one.
Multiple screws are connected on the compression ring 6, the axis of the screw is in the same plane, and the screw encloses
Axis around the compression ring 6 is uniformly distributed, and the compression ring 6 squeezes the connecting shaft 3 by screw and is fixed on institute to realize
It states in connecting shaft 3.
The working principle of the invention is:
When installation, rectangular strip 2-5 and resistance are stopped into 2-6 out of rotation slot 1-2 first and passed through, so that resistance stops a 2-6 and is located at
The outside of connecting plate 1.Connecting cylinder 3-2 is covered on multi-diameter shaft 3-1, and the small end of multi-diameter shaft 3-1 is worn out of connecting hole 1-1
Out, so that the small end of multi-diameter shaft 3-1 is located at the outside of connecting plate 1, stop a 2-6 with resistance and be in the same side.Block 2 is passed through into connection
Ring 2-1 covers on multi-diameter shaft 3-1 and adjusts the size of slot 2-1-1 opening, so that block 2 can not be detached from from multi-diameter shaft 3-1,
It can be rotated on multi-diameter shaft 3-1 again.Multi-diameter shaft 3-1 is rotatably connected on connecting plate 1 by bearing I 4.By the fixed company of gear 7
The small end in multi-diameter shaft 3-1 is connect, it is corresponding to stop the position of a 2-6 with resistance, so that block 2 rotates one on the multi-diameter shaft 3-1
When determining angle, the card that the resistance stops on a 2-6 stops tooth 2-6-1 and engages with the gear 7, so that the gear 7 stops operating.Its
It is secondary, I 3-4 of axis is rotatably connected on connecting plate 1 by bearing II 5, two compression rings 6 and coiled bag on roll are covered in axis II
On 3-3, and coiled bag on roll is fixed between two compression rings 6, fixes two compression rings 6 and coiled bag on roll is turned
It will drive the rotation of compression ring 6 when dynamic, the rotation band of compression ring 6 II 3-3 of moving axis is rotated.Then, by connecting cylinder 3-2 by multi-diameter shaft 3-
1 and II 3-3 of axis is fixed together, so that II 3-3 of axis rotation will drive multi-diameter shaft 3-1 rotation, thus with 7 turns of moving gear
It is dynamic.
It is singlehanded quickly to pull bag on roll when tearing bag on roll, it is to pull from the bottom to the top and from even when pulling bag on roll
It rolls up bag one end to pull to operator one end, so that bag on roll rotates cylindrical body 2-4 to this end of operator, so that block
2 rotate on multi-diameter shaft 3-1, and after turning an angle, the card that resistance stops on a 2-6, which stops tooth 2-6-1, to be engaged with gear 7, so that
The gear 7 stops operating.For 7 meeting of gear so that multi-diameter shaft 3-1 stops operating, multi-diameter shaft 3-1 makes axis II by connecting cylinder 3-2
3-3 stops operating, and II 3-3 of axis then makes compression ring 6 stop operating, so that coiled bag on roll stops operating.At
The moment that the bag on roll of volume stops operating, the pulling force that bag on roll receives can make the separator bar between bag on roll be destroyed, thus
Bag on roll is torn from coiled bag on roll.After bag on roll is torn, cylindrical body 2-4 is no longer influenced by the power of bag on roll, in weight
Cylindrical body 2-4 can be rotated to oppositely oriented direction under the action of power, so that card stops tooth 2-6-1 and separates with gear 7, be convenient for
Bag on roll is torn next time.
When replacing bag on roll, firstly, to direction rotation axis II 3-3 oppositely oriented with tearing bag on roll, while being hindered with hand
Only connecting cylinder 3-2 is rotated, can be quickly by connecting cylinder 3-2 from bumping post 3-1-1 and axis II using the principle of screw nut driving
It is separated on 3-3.Then, II 3-3 of rotation axis, convenient for unloading the compression ring 6 for being located at the one end connecting cylinder 3-2, to replace in rolls
Bag on roll.After replacement, method when by compression ring 6 according to installation is fixed on II 3-3 of axis.Finally, side when according to installation
Rotation axis II 3-3 and multi-diameter shaft 3-1 are fixed together by method with connecting cylinder 3-2.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, the art
The variations, modifications, additions or substitutions that those of ordinary skill is made within the essential scope of the present invention also belong to guarantor of the invention
Protect range.
