Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of dry compound machine feeding roller
Fixing device, has feeding roller and removes and installs more convenient advantage.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of dry compound machine send
The fixing device of material roller, including frame and feeding roller, the two ends of described feeding roller are provided with rotating shaft, and the end of described rotating shaft rotates even
Being connected to connecting shaft, described frame is provided with circumferentially fixed assembly and axial restraint assembly；
Described circumferentially fixed assembly includes the fixed station being fixed in frame, the caulking groove being opened on fixed station, is hinged on
Clip, the fixing groove being opened on clip on fixed station and be threaded in the fixture on clip and fixed station simultaneously,
Described caulking groove and fixing groove are conflicted on the surface of connecting shaft；
Described axial restraint assembly includes the supporting table being fixed on described fixed station, is fixed on described supporting table and fixes
Sleeve, it is located in fixing sleeve and abuts bar and the fixation kit for fixing abutting bar for push against connecting shaft；
Described fixation kit include being opened in abut on bar abut mouth, be located in abut in mouth pusher rod, two groups pairs
Claim be arranged on the fixing voussoir group abutted on mouth inwall and be arranged on fixing sleeve lining for pushing against fixing voussoir group
Abutting block group, each described fixing voussoir group includes being slidably connected at the fixing voussoir abutted on mouth diapire and two ends are fixed respectively
At fixing voussoir and the elastic component that abuts on mouth inwall, and under original state, the end face of two fixing voussoirs is affixed merging and draws in and exist
In abutting bar；
The end of described pusher rod is provided with on wedge shaped abutment plane and described fixing voussoir to offer and abuts with described
The slide surface that plane matches；When described pusher rod is inserted between fixing voussoir, described fixing voussoir stretch out abutting bar and with support
Connect block group inconsistent, and conflict on the surface of pusher rod in the end of fixing voussoir.
By using technique scheme, owing to connecting shaft is connected with axis of rotation, when connecting shaft is fixed, rotating shaft is still
Can rotate, and drive feeding roller to rotate during rotating, thus realize the function of feeding；When feeding roller is installed, first will
Connecting shaft is erected in the caulking groove on fixed station, and the surface fixing groove and connecting shaft when rotating clip subsequently fits, and then twists
Fastening locking member, fixture is threaded on fixed station, and is pressed in connecting shaft by clip, so that connecting shaft and fixed station
It is relatively fixed；Promote abutting bar to the most inconsistent with the end face of connecting shaft subsequently, the most inwardly promote pusher rod, make pusher rod insert
Fix between voussoir to two, now fix voussoir and stretch out outside abutting bar and conflict in abutting block group, and the end of fixing voussoir
Conflict on the surface of pusher rod, be pressed in pusher rod under the effect of elastic component elastic force, so that connecting shaft is axial simultaneously
Be relatively fixed, i.e. the circumferential and axial of connecting shaft have been fixed in frame the most relatively, install fixation procedure simple and convenient；During dismounting
Fixture is unscrewed and clip is overturn to side, pusher rod is outwards extracted out one end distance, fixing voussoir supporting at elastic component
Touching down and i.e. draw in abutting bar, abut bar and can be moved rearwards by being disconnected axle, unloading process is the most quick.
This utility model is further arranged to: described abutting block group includes being symmetricly set on pushing against on fixing sleeve lining
Block.
