Description

Dismount convenient roller clamping mechanism

Technical field

The utility model belongs to technical field of film preparation, more particularly, to a kind of convenient roller clamping mechanism of dismounting.

Background technique

In the film production process, need the miscellaneous roller such as delivery roll, idler roller, wind-up roll, some rollers need through Often dismounting, if using existing roller installation in screw, nut be fixedly mounted by the way of, will lead to dismounting it is time-consuming and laborious, and by It is smaller in the opening of mounted roller, it is unfavorable for quickly being put into for the bearing being set on roller, additionally due to the openings of sizes of mounted roller Be it is fixed, the scope of application is small.

Utility model content

The purpose of this utility model be in view of the above-mentioned problems, provide it is a kind of design rationally, solve roller it is easy to disassemble and increase Add the convenient roller clamping mechanism of the dismounting of scope of application problem.

In order to achieve the above objectives, the utility model uses following technical proposal: the convenient roller of the dismounting of the utility model With clamping mechanism, on the lateral side of rack, including the fixing seat being connect with rack, be convexly equipped at the top of fixing seat two be between Every the first clamp and the second clamp of setting, it is characterised in that: the first clamp upper inner, which offers, to be tilted upward and outside First inclination folder face, the second clamp upper inner, which offers, to be tilted upward and the second outside inclination folder face, the bottom of the first clamp The spacing of the side of the bottom adjacent side of portion and the second clamp is less than the winding bearing of the outside on external wind-up roll The spacing of the opposite upper in outer diameter, the opposite upper in the first inclination folder face and the second inclination folder face is greater than the outer diameter of winding bearing； Second clamp is telescopic mast；It is equipped between first clamp and the second clamp for adjusting between the second clamp and the first clamp spacing Away from component is adjusted, it includes the clamp between the second clamp and the first clamp on fixing seat top that spacing, which adjusts component, Sliding rail, clamp sliding rail cooperate with the clamp card slot for being opened in the second clamp lower end.First inclination folder face and the second inclination folder face are in The setting of herringbone facilitates winding bearing and is quickly inserted in and is sandwiched between the first clamp and the second clamp, when disassembly, only needs Shrinking the second clamp flushes its top planes with fixing seat top planes, and wind-up roll is facilitated quickly to remove, and spacing adjusts component Setting facilitate spacing between the second clamp and the first clamp adjusted according to the size of winding bearing, enhance applicable model It encloses.

Preferably, the arcwall face of to be all for cross section be the first inclination folder face and the second inclination folder face arc.Increase with Wind the contact area of bearing.

Preferably, fixing seat top end face and rack top end face are located at same level.Facilitate the installation of winding bearing.

Preferably, the first clamp is linked together with fixing seat.Improve the working strength of the first clamp.

Preferably, the clamp positioning screw hole being in communication with the outside, clamp positioning are offered in at least one side wall of clamp card slot Screw hole cooperates to connect positioning bolt with clamp sliding rail with positioning bolt.The setting of clamp positioning screw hole and positioning bolt increases The strong bonding strength of second clamp and clamp sliding rail.

Preferably, the cross section of clamp sliding rail is I-shaped, and size, the shape of clamp card slot are adapted with clamp sliding rail. By increasing contact area, enhances the firmness of the connection of the second clamp and clamp sliding rail, improve the stability of wind-up roll operation.

Compared with prior art, the advantages of this dismounting convenient roller clamping mechanism is: the second clamp is telescopic mast, is torn open When unloading, only need to shrink the second clamp flushes its top planes with fixing seat top planes, and wind-up roll is facilitated quickly to remove；Spacing The setting for adjusting component is facilitated according to the spacing between size the second clamp of adjustment of winding bearing and the first clamp, is enhanced The scope of application；The spacing of the opposite upper in the first inclination folder face and the opposite upper in the second inclination folder face is greater than the outer of winding bearing Diameter, the first inclination folder face and the second inclination folder face facilitate winding bearing in the setting of herringbone and are quickly inserted in and are sandwiched in first Between clamp and the second clamp.
