Abstract
The utility model provides a power transmission structure for a paper rolling disk. The power transmission structure comprises a spindle and a belt pulley, and is characterized in that: the belt pulley is sleeved on the spindle through a bearing in an idle way; the spindle is fixedly provided with a first frictional disk and a second frictional disk at an interval; the belt pulley is positioned between the first frictional disk and the second frictional disk; and two end faces of the belt pulley are in friction contact with the first and second frictional disks. The rotation speed of the paper rolling disk can be automatically controlled, and metal strip packing paper on the paper rolling disk is always kept at constant tension, so that the paper collecting speed of the paper rolling disk is kept synchronous with the self-release speed of the packing paper; and therefore, the constant tension of the metal strip packing paper on the paper rolling disk is kept and the paper rolling efficiency is improved.
Description
Technical field
The utility model relates to a kind of power transmission structure, relates in particular to a kind of power transmission structure of paper tray.
Background technology
The rolling work of metal tape interleaving paper is accomplished through paper tray, and paper tray drives paper tray through Poewr transmission mechanism and rotates the collection work of accomplishing, in the process of collection work; The collection speed that must guarantee paper tray is identical with the speed that unreels certainly of metal tape interleaving paper; If the collection speed that furls paper disc then can not realize synchronous collection less than unreeling speed certainly, if the collection speed of paper tray is greater than unreeling speed certainly; It is big that the tension force of packing paper becomes, thereby damage packing paper.The power transmission structure of existing paper tray comprises main shaft and is fixed on the belt pulley on the main shaft; Belt pulley is through driven by motor choosing dress; Therefore the velocity of rotation of main shaft can not be automatically along with the metal tape interleaving paper changes from the change of the speed of unreeling; Therefore the metal tape interleaving paper can not keep permanent tension force, can not realize synchronous collection or cause the fracture of metal tape interleaving paper easily.
The utility model content
The technical matters that the utility model solves is: a kind of power transmission structure of paper tray simple in structure is provided, and rotative speed that can the automatic guidance paper tray makes the metal tape interleaving paper on the paper tray remain permanent tension force.
The technical scheme of the utility model is: a kind of power transmission structure of paper tray; Comprise main shaft and belt pulley; It is characterized in that said belt pulley is enclosed within on the main shaft through the bearing sky, be fixed with spaced first friction disc and second friction disc on the said main shaft; Said belt pulley between first friction disc and second friction disc, the both ends of the surface of belt pulley wipe contact respectively and between first friction disc, second friction disc.
Said main shaft is provided with outside thread, and said second friction disc is through being threaded on the main shaft.
Said second friction disc is provided with axially extended cylinder, and this cylinder passes through screw retention on main shaft.
The beneficial effect of the utility model is: during use; The belt pulley of the utility model is connected with motor through belt, and belt pulley does not directly drive the main shaft rotation, but drives the main shaft rotation through first friction disc of driven pulley and its both sides, friction force between second friction disc; Regulate the collection tension force size of main shaft; And the speed that makes belt pulley is slightly larger than the speed that unreels certainly of packing paper, makes to be in slipping state all the time between two end faces of belt pulley and first friction disc, second friction disc rotative speed that therefore can the automatic guidance paper tray; Make the metal tape interleaving paper on the paper tray remain permanent tension force; Make that the collection speed of paper tray is synchronous with the speed that unreels the certainly maintenance of packing paper all the time, thereby keep the permanent tension force of the metal tape interleaving paper on the paper tray, improve coil paper efficient.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the state reference map of installing and using of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Referring to Fig. 1; A kind of power transmission structure of paper tray; Comprise main shaft 1 and belt pulley 2, belt pulley 2 is enclosed within on the main shaft 1 through bearing 3 skies, is fixed with spaced first friction disc 4 and second friction disc 5 on the main shaft 1; Belt pulley 2 between first friction disc 4 and second friction disc 5, the both ends of the surface of belt pulley 2 wipe contact respectively and between first friction disc 4, second friction disc 5.For the ease of regulating the friction force size between the belt pulley 2 and second friction disc 5; On main shaft 1, be provided with outside thread; Second friction disc 5 is through being threaded on the main shaft 1; And second friction disc 5 is provided with axially extended cylinder, and this cylinder, rotates thereby prevent to produce circumferentially between second friction disc 5 and the main shaft 1 on main shaft 1 through screw retention; Therefore can adjust the pressure between second friction disc and the belt pulley, and then realize regulating the friction force size between the belt pulley and second friction disc.
The utility model is installed and used like this: referring to Fig. 2, paper tray 6 is installed on the main shaft 1, and main shaft 1 is installed on the base 8 through bearing seat 7, is fixed with motor 9 on the base 8, is connected through belt 11 between the belt pulley 2 on the main shaft and the motor pulley 10.After motor 9 starts, idle running between the belt pulley 2 on the main shaft and the main shaft 1, the belt pulley 2 on the main shaft drives first friction disc 4,5 rotations of second friction disc through friction force, thus first friction disc 4 drives 6 rotations of main shafts 1 rotation drive paper tray with second friction disc 5.
