Abstract
The utility model provides a power transmission device for a paper reeling disc. The power transmission device for the paper reeling disc comprises a main shaft and a pulley and is characterized in that: the pulley is hollowly sleeved on the main shaft through a bearing; a first friction disc and a second friction disc are arranged on two sides of the pulley; two sides of the pulley are in frictional contact with the first friction disc and the second friction disc respectively; the first friction disc is fixed with the main shaft; the second friction disc is fixed with the main shaft circumferentially and can move in the axial direction of the main shaft; the main shaft is provided with external thread; an adjusting nut is arranged on the external thread part of the main shaft; and a compression spring is sleeved on the main shaft and positioned between the second friction disc and the adjusting nut. The power transmission device for the paper reeling disc can automatically control the rotating speed of the paper reeling disc, so that metal belt material packing paper on the paper reeling disc still maintains constant tensile force, the paper-reeling speed of the main shaft still maintains synchronous with the automatically unreeling speed of the metal belt material packing paper, the tensile force of the metal belt material packing paper on the paper reeling disc is maintained and paper-reeling efficiency is improved.
Description
Technical field
The utility model relates to a kind of torque transfer, relates in particular to a kind of torque transfer 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 torque transfer 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 of paper tray 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 torque transfer 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 torque transfer 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 torque transfer of paper tray, comprise main shaft and belt pulley, and it is characterized in that; Said belt pulley is enclosed within on the main shaft through the bearing sky, and the both sides of belt pulley are provided with first friction disc and second friction disc, the two sides of belt pulley wipe contact respectively and between first friction disc, second friction disc; Wherein, first friction disc and main shaft fix, and be circumferentially fixing between second friction disc and the main shaft; And second friction disc can be along the moving axially of main shaft, and said main shaft is provided with outside thread, and the external thread part of main shaft is provided with setting nut; One compression spring is set on the main shaft, and compression spring is between second friction disc and setting nut.
Said main shaft is provided with axial male splines, and the centre hole of said second friction disc is provided with axial female splines, and the female splines of second friction disc matches with the male splines of 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; Friction force size between second friction disc and the belt pulley is confirmed by the elastic force that compression spring produces; The elastic force that compression spring produces can be adjusted through setting nut, regulates the collection tension force size of main shaft, and makes the speed of belt pulley be slightly larger than the speed that unreels certainly of metal tape interleaving paper; Make and be in slipping state all the time between two sides of belt pulley and first friction disc, second friction disc; Therefore rotative speed that can the automatic guidance paper tray makes the metal tape interleaving paper on the paper tray remain permanent tension force, and the collection speed of paper tray keeps synchronously with the speed that unreels certainly of metal tape interleaving paper all the time; Thereby the permanent tension force of the metal tape interleaving paper on the maintenance paper tray improves coil paper efficient.
