Shaftless liquid gallows with adjustable brake system
Technical field
This utility model relates to hydraulic pressure paper frame mechanism, relate to the shaftless liquid gallows with adjustable brake 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.
Summary of the invention
This utility model is for complicated, the relatively costly shortcoming of brake disc structure in prior art, it is provided that band
There is the shaftless liquid gallows of adjustable brake system.
In order to solve above-mentioned technical problem, this utility model is addressed by following technical proposals:

End face is provided with hole, is provided with rubber ring in hole, clamp arm is provided with motor and by motor control movement
Braking column, braking column be cone, the summit of braking column towards hole direction arrange, the appearance of braking column
Face is provided with multiple circular hole, is mounted on ball in each circular hole, and braking column is come by the degree of depth inserted in the hole
Control braking column to the thrust of rubber ring and paper holder is played regulation rotating speed function.The circular cone of braking column
Shape arranges and makes coordinating between its with rubber ring can regulate compression, is stretched into the degree of depth in hole by braking column, adjusts
Save the thrust between braking column 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.
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.

Detailed description of the invention
With embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1
With the shaftless liquid gallows of adjustable brake 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 12
Circular hole 61, is mounted on ball 62 in each circular hole 61, the degree of depth of circular hole 61 is less than the diameter of ball 62,
Ball 62 outwardly convex, protruding and form arch on the taper surface of braking column 6, the arcuate surface of this projection with
Rubber ring 42 contacts and contacts rubber ring 42, when static braking column 6 is direct with the paper holder 4 in rotation
During contact, the contact area of braking column 6 and paper holder 4 can be made to reduce by the design of ball 62 and play slow
The effect of punching, prevents braking column 6 and rubber ring 42 impaired, and braking column 6 is by inserting the degree of depth in hole 41
Control braking column 6 to the thrust of rubber ring 42 and paper holder 4 is played regulation rotating speed function.Clamping
Guide rail 31 is installed on arm 3, braking column 6 is provided with the slide block 63 coordinated with guide rail 31, on motor 5
Being provided with gear 8, slide block 63 is provided with the tooth bar 631 coordinated with gear 8, and motor 5 is by gear 8 He
The mating band movable slider 63 of tooth bar 631 moves, and slide block 63 drives braking column 6 to move in hole 41.Motor
5 driven gears 8 rotate, and gear 8 drives the slide block 63 being provided with tooth bar 631 to slide on guide rail 31, brake
Post 6 is realized displacement by the effect of slide block 63, when braking column 6 puts in hole 41, on braking column 6
Ball 62 contacts with rubber ring 42 and produces frictional force, now serves the effect of slowly braking;Work as brake
Post 6 continues deeper into hole 41, owing to braking column 6 is tapered pole, therefore ball 62 rubber ring 42 is produced by
Thrust that gradual change is big also reduces the rotating speed of paper holder 4 thus reaches the purpose of Quick brake.On paper holder 4
It is provided with the convex tendon 43 for increasing 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.
