There is the shaftless liquid gallows of brake adjustment system
Technical field
This utility model relates to hydraulic pressure paper frame mechanism, relate to the shaftless liquid gallows with brake adjustment system.
Background technology
The paper rack brake disc of corrugated paper production line is tension force in time controlling that in production process, paper roll unreels.
Certain tension force must be remained when body paper unreels during corrugated board production, and tension force is wanted uniformly
Constant just can prevent paper not wrinkle from not relaxing, thus ensure the quality of production of corrugated paper.Chinese patent is open
A kind of zero speed paper holder electro-magnetic tension friction disk (Authorization Notice No.: CN 201068944Y), it has and interconnects mutually
The paper frame wallboard connect and steel housings, housing and iron core, magnesium iron brake disc surround a cavity, in it jointly
If being surrounded by the coil of resin bed, brake disc is fixed on guiding mandrel by nylon guide pin bushing, brake disc and housing,
Being vertically arranged the iron disc of channel steel shape between iron core, brake block is placed in the groove of disc, and its side is close to
On brake disc, between disc and resin bed, form a space, disc is machined with one group of through hole, space
Width range is 3~5mm, and nylon guide pin bushing is shaped with shaft shoulder side towards the input guiding mandrel.But this stop
The structure of hull is complex, and manufacturing cost is higher, and during existing brake disc regulation brake degree of tightness, can only
Manually regulate by screw rod, adjust to obtain the paper that the most easily breaks, adjust pine paper not have pulling force that product is had an impact.

The cone of post arranges and makes coordinating between its with rubber ring can regulate compression, is stretched in hole by braking column
The degree of depth, regulates the thrust between braking column and rubber ring and brake is played the effect that regulation controls, can pin
Different brake requires to realize emergency brake or the progressively function such as brake, simple to operate, easy left-hand seat.
As preferably, clamp arm is provided with guide rail, braking column is provided with the slide block coordinated with guide rail, electricity
Being provided with gear on machine, slide block is provided with the tooth bar coordinated with gear, and motor passes through gear and the cooperation of tooth bar
Band movable slider moves, and slide block drives braking column to move in hole.Braking column can be controlled by the rotation of motor
Translational speed, simple to operate, easy left-hand seat.
As preferably, paper holder is provided with for increasing the convex tendon of frictional force between paper holder and paper roll.Pass through
Paper roll can be preferably controlled by convex tendon, prevents the situation of paper roll idle running.
This utility model, owing to have employed above technical scheme, has a significant technique effect: the circle of braking column
Taper arranges and makes coordinating between its with rubber ring can regulate compression, is stretched into the degree of depth in hole by braking column,
Regulate the thrust between ball and rubber ring and the effect that regulation controls is played in brake, can be for different
Brake requirement realizes emergency brake or the progressively function such as brake, simple to operate, easy left-hand seat.

The toponym that in accompanying drawing, each number designation is referred to is as follows: 1 frame, 2 main shafts, 3 clamp arms,
4 paper holders, 5 motors, 6 braking columns, 7 fixed arms, 8 gears, 31 guide rails, 41 holes,
42 rubber rings, 43 convex tendons, 61 annular grooves, 62 balls, 63 slide blocks, 631 tooth bars.
Detailed description of the invention
With embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1
There is the shaftless liquid gallows of brake adjustment system, as it can be seen, include frame 1 and be arranged on frame 1
On main shaft 2, main shaft 2 is provided with fixed arm 7 and the clamp arm 3 moved horizontally, fixed arm 7 and clamping
Being mounted on paper holder 4 on arm 3, paper roll is by the paper holder 4 on fixed arm 7 and the tray paper on clamp arm 3
Device 4 is arranged in frame 1, and the end face outside of paper holder 4 is provided with hole 41, is provided with rubber ring in hole 41
42, clamp arm 3 is provided with motor 5 and the braking column 6 being controlled by motor 5 and moving, braking column 6 is circle
Taper, the summit of braking column 6 is arranged towards the direction in hole 41, and the outer surface of braking column 6 is provided with three rings
Connected in star 61, is mounted on ball 62 in each annular groove 61, the degree of depth of annular groove 61 is less than ball
The diameter of 62, ball 62 outwardly convex, protruding and form arch on the taper surface of braking column 6, this projection
Arcuate surface contact with rubber ring 42 and rubber ring 42 contacted, when static braking column 6 with rotate in torr
When paper device 4 directly contacts, the contact area of braking column 6 and paper holder 4 can be made to subtract by the design of ball 62
Little and play the effect of buffering, prevent braking column 6 and rubber ring 42 impaired, braking column 6 is by inserting hole 41
In the degree of depth control braking column 6 to the thrust of rubber ring 42 and paper holder 4 is played regulation rotating speed merit
Energy.Guide rail 31 is installed on clamp arm 3, braking column 6 is provided with the slide block 63 coordinated with guide rail 31,
Being provided with gear 8 on motor 5, slide block 63 is provided with the tooth bar 631 coordinated with gear 8, and motor 5 passes through
The mating band movable slider 63 of gear 8 and tooth bar 631 moves, and slide block 63 drives braking column 6 to move in hole 41
Dynamic.Motor 5 driven gear 8 rotates, and gear 8 drives and is provided with the slide block 63 of tooth bar 631 on guide rail 31
Sliding, braking column 6 is realized displacement by the effect of slide block 63, when braking column 6 puts in hole 41, stops
Ball 62 on car post 6 contacts with rubber ring 42, prevents braking column 6 directly contacting also rubber ring 42
Cause braking column 6 and the damage of rubber ring 42, now serve the effect of slowly braking;When braking column 6 continues
Continuing and go deep into hole 41, owing to braking column 6 is tapered pole, therefore rubber ring 42 is produced and becomes larger by braking column 6
Thrust and reduce the rotating speed of paper holder 4 thus reach the purpose of Quick brake.Paper holder 4 is provided with use
In increasing the convex tendon 43 of frictional force between paper holder 4 and paper roll.
In a word, the foregoing is only preferred embodiment of the present utility model, all apply for a patent according to this utility model
Equalization change and the modification that scope is made, all should belong to the covering scope of this utility model patent.
