Abstract
The utility model discloses an automatic expansion mechanism used for coiling and uncoiling a chart drum. The automatic expansion mechanism used for coiling and uncoiling the chart drum is characterized in that a movable automatic expansion choke plug is connected with a driving shaft through a locating key and an inner hole, the movable automatic expansion choke plug is enabled to move in the shaft direction relative to the driving shaft, and the movable automatic expansion choke plug is driven to rotate by the driving shaft. When the movable automatic expansion choke plug extends out, an automatic expansion key retracts, and on the contrary, the automatic expansion key expands. According to the automatic expansion mechanism used for coiling and uncoiling the chart drum, the movable automatic expansion choke plug is enabled to be in a retracted state through a spring, a blocking disc and a clamping ring when the movable automatic expansion choke plug does not work. When materials are loaded, air enters an air cylinder, crosswise force is given to a normal choke plug, and then the normal choke plug pulls a roll paper core to move to the movable automatic expansion choke plug. The spring is pressed, so the movable automatic expansion choke plug retracts, then the automatic expansion key expands, the roll paper core is expanded, and the operation of loading the material is finished. The automatic expansion mechanism used for coiling and uncoiling the chart drum has the advantages that the structure is reasonable, and the space is reduced; movements are all mechanical, and pollution and emission are reduced; the clamp force is strong and non-slip; the roll paper core is not prone to abrasion and can be recycled, so the cost is saved, resources are saved, the structure is simple and materials are saved and the like.
Description
Technical field
The utility model relates to a kind of automatic expansion mechanism, is specifically related to a kind of for the automatic expansion mechanism of unwinding and rewinding paper web.
Background technology
Along with the progress of society, the development of science and technology, the unwinding and rewinding mechanism that exists on the market does not possess automatic swelling function, and the paper web of loading onto is looser; When unwinding and rewinding, paper web is loose, and tension force is little, and skidding occurs often, thereby makes tension force control inaccurate, has affected greatly overall performance; Production is brought inconvenience.Simultaneously very easily damage paper web, the recycling rate of paper web is low, does not meet the demand of modern society.
The utility model content
The utility model has overcome the shortcoming of prior art, provides a kind of for the automatic expansion mechanism of unwinding and rewinding paper web.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of for the automatic expansion mechanism of unwinding and rewinding paper web, it is characterized in that horizontal rigid drive shaft fixes by bearing seat, the tail end key connects synchronous pulley, mobilely is connected with imput shaft with endoporus by positioning key from swollen plug, making it relative imput shaft can axially move, and by the imput shaft driven rotary; The imput shaft front end has tapering, from swollen key bottom tapering is arranged also, and overlap with imput shaft, when mobile plug stretched out, certainly swollen key shrank, otherwise, from swollen key distending, this mechanism makes mobile certainly swollen plug be in contraction state from swollen key when not working by spring, stifled dish and snap ring, when our material loading, common stifled first transverse force is given in the cylinder ventilation, and common plug promotion this moment paper core moves, push to mobile from swollen plug, Compress Spring makes mobile certainly swollen plug indentation, and this moment is from swollen key expansion, the swelling paper core is finished the material loading operation; Regulate in addition stop nut and can change swell diameter from swollen key.
With respect to prior art, the utlity model has following advantage:
1, rational in infrastructure, reduce the space;
2, full mechanical action, fault rate is little;
3, gripping power is large, and is non-slip, impels the control of tension force and speed stable, thereby promoted overall performance;
4, paper core is not easy to wear, can be recycled, and Cost reduction economizes on resources;
5, simple in structure, economical with materials.

Fig. 1 is structural principle partition schematic diagram of the present utility model;
Fig. 2 is principle of work schematic diagram of the present utility model.
The specific embodiment
Shown in Fig. 1-2, a kind of for the automatic expansion mechanism of unwinding and rewinding paper web, it is characterized in that horizontal rigid drive shaft 1 fixes by bearing seat, the tail end key connects synchronous pulley, mobile certainly swollen plug 2 is connected with imput shaft 1 with endoporus by positioning key 8, making it relative imput shaft 1 can axially move, and by imput shaft 1 driven rotary; Imput shaft 1 front end has tapering, from swollen key 3 bottoms tapering is arranged also, and overlap with imput shaft 1, mobile when swollen plug 2 stretches out, certainly swollen key 3 shrinks, otherwise, from swollen key 3 distendings, this mechanism is by spring 4, stifled dish 5 and snap ring 6 make mobile certainly swollen plug 2 be in contraction state from swollen key 3 when not working, when our material loading, 10 1 transverse forces of common plug are given in cylinder 11 ventilations, and this moment, common plug 10 promotion paper core 9 moved, push to mobile from swollen plug 2, Compress Spring 3 makes mobile certainly swollen plug 2 indentations, and this moment is from swollen key 3 expansions, swelling paper core 9 is finished the material loading operation; Regulate in addition stop nut 7 and can change swell diameter from swollen key 3.
