Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art all belong to the protection scope of the present invention.
The embodiment of the utility model provides a:
the ladder axle generally adopts numerical control lathe to turn and mill and process out, to traditional roll paper roller, it also adopts this mode design production equally, roll paper roller and be equivalent to the great section of radial dimension in the traditional ladder axle, this kind of traditional roll paper roller and axis of rotation design as an organic whole, roll paper roller and can't remove in the axis of rotation, after long-time work, roll the periphery of paper roller and will take place certain wearing and tearing, finally lead to whole roll paper roller to damage or even scrap.
In order to reduce the rejection rate of the stepped shaft and improve the repair process of the damaged paper rolling roller, a movable paper rolling roller 1 is specially designed, as shown in fig. 1-2, the movable paper rolling roller comprises a paper rolling roller 1 and a rotating shaft 2, and the paper rolling roller 1 and the rotating shaft 2 in the technical scheme can be separated; the axis of rotation 2 is the same with the axis of rotation in the original traditional paper rolls roller, and both ends all are equipped with the ladder section that is used for cup jointing the bearing, and the radial dimension in middle part is unanimous for set up paper rolls roller 1. In the present embodiment, the axial direction of the rotating shaft 2 is defined as the left-right direction.
A matching hole 12 penetrates through the left side and the right side of the paper rolling roller 1, one end of the matching hole 12 is opened on the left end face of the paper rolling roller 1, and the other end of the matching hole 12 is opened on the right end face of the paper rolling roller 1; the size of mating holes 12 agrees with 2 radial dimensions of axis of rotation each other, and the drum 1 of grinding is established on axis of rotation 2 through mating holes 12 cover, and the concrete degree of agreeing with characterization is: the paper rolls 1 can be moved on the rotating shaft 2 by an axially outward force. The paper grinding roller is characterized in that fixing holes are radially arranged on the circumferential surface of the paper grinding roller 1 at positions relatively close to the two ends, one ends of the fixing holes are opened in the matching holes 12, the other ends of the fixing holes are opened on the circumferential surface of the paper grinding roller 1, the number of the fixing holes is three at the left end of the paper grinding roller 1, the fixing holes are uniformly distributed at intervals along the circumferential surface of the paper grinding roller 1, the number of the fixing holes is also three at the right end of the paper grinding roller 1, and the distribution mode is the same as that of the fixing holes at the left end; the fixing hole in this embodiment is threaded hole 11, and when the paper grinding roll 1 is sleeved on the rotating shaft 2, the jackscrew can be screwed into the threaded hole 11, so that the axial movement of the paper grinding roll 1 can be limited.
The paper grinding roller 1 is provided with a friction part 10, the friction part 10 is straight knurling, and the friction part 10 is arranged on the circumferential surface of the paper grinding roller 1 and used for increasing the friction force between the paper grinding roller 1 and the friction part 10.
In this embodiment, two paper rolls 1 are provided, and the two paper rolls 1 are arranged at a left-right interval and sleeved on the rotating shaft 2.
The working principle is as follows:
the two paper grinding rolls 1 are sequentially sleeved on the two paper grinding rolls 1, and the jackscrews in the two paper grinding rolls 1 are screwed into the threaded holes 11 at corresponding positions respectively, so that the paper grinding rolls 1 are fixed on the rotating shaft 2. In the working process, one section of circumferential surface of the two paper grinding rollers 1 is contacted with paper to be conveyed, and the paper is conveyed continuously under the drive of the rotating shaft 2. In the actual use process, the two paper rolling rollers 1 can be axially moved by workers to meet the requirement of the paper rolling rollers 1 on adjustment of the friction force of paper, compared with the traditional integrated paper rolling roller, the movable paper rolling roller can directly separate the paper rolling roller 1 from the rotating shaft 2 when being repaired at the later stage, and the repairing process is more convenient and flexible than before; moreover, in this movable paper roll, after one section friction part 10 in paper roll 1 was worn and torn, can take off two paper portions of grinding from axis of rotation 2, control and transfer 180, overlap according to former route cover again and establish on axis of rotation 2, this can let out the part of wearing and tearing in original two paper rolls 1, makes the part of not wearing and tearing contact with the paper, has fully guaranteed paper roll 1's utilization ratio, has also reduced manufacturing cost simultaneously.
