Description
Technical field
The utility model relates to band sawing machine technical fields, more particularly to a kind of anti-sticking sawed-off saw device.
Background technique
Band sawing machine generally connects driving wheel, follower, pulley tightener by saw blade and carries out shuttling movement, utilizes the steel on saw blade
Tooth cuts steel.Due in saw blade sawing process always using from up to down, the penetration of a cutting tool mode of traverse feed, and process
In two degree of adjustings generally will not be carried out artificially for the revolving speed of sawing machine, once therefore steel middle position occur excessive high hardness or
There is the case where impurity, it is most likely that cause saw blade to block, however the speed of direction of feed is unaffected.Generally occur such
Situation finds to will lead to carry out frontal impact between saw blade and steel not in time, the case where being broken after saw blade is pullled occurs.
Chinese Patent Application No.: 200720184152.7, a kind of band-rapture safety arrangement for band sawing machine is disclosed, it
Including the backstand being mounted on saw frame, which is equipped with the tensioning sliding block that can be horizontally slipped, tension screw right end activity
Backstand is stretched out in connection tensioning sliding block, left end sliding, and is socketed compressed spring and connection handwheel, and tensioning sliding block is equipped with movement
Plate, movable plate left are correspondingly provided with microswitch.
Foregoing invention creation structure is complex, and cost of manufacture is higher.
Utility model content
The purpose of this utility model is that overcoming the drawbacks described above of the prior art, a kind of anti-sticking sawed-off saw device is provided.
To achieve the above object, the technical scheme that the utility model is provided is as follows: a kind of anti-sticking sawed-off saw device, including saw
Bed fuselage, sawing machine fuselage bottom be equipped with power switch, sawing machine fuselage be equipped with buck, buck be equipped with driving wheel, follower and
Tensioning wheel is connected with saw blade between driving wheel, follower and tensioning wheel, side is equipped with round fixinig plate at follower axle center,
Rule is convexly equipped with several raised lines around in the round fixinig plate center of circle, and sawing machine fuselage corresponds to follower side equipped with column, column top
Corresponding raised line side is held to be equipped with speed sensor.
Further, the spacing between speed sensor and raised line is 1 to 3cm.
Further, power switch, which is electrically connected, is equipped with relay.
Further, relay and speed sensor are electrically connected.
The benificial effect of the utility model is to structure is simple, the disconnected saw of saw blade can be prevented by autostop after saw blade card saw,
It should be widely promoted.
Detailed description of the invention
Fig. 1 is a kind of overall structure diagram of anti-sticking sawed-off saw device of the utility model；
Fig. 2 is a kind of follower stereoscopic schematic diagram of anti-sticking sawed-off saw device of the utility model.
Specific embodiment
With reference to the accompanying drawing and preferred embodiment is further described with regard to the technical solution of the utility model.
As Figure 1-Figure 2, the anti-sticking sawed-off saw device of one kind described in the utility model, including sawing machine fuselage 1, sawing machine machine
1 bottom of body is equipped with power switch (not shown), and sawing machine fuselage 1 is equipped with buck 2, and buck 2 is equipped with driving wheel (in figure not
Show), follower 3 and tensioning wheel 4, saw blade 5 is connected between driving wheel, follower 3 and tensioning wheel 4, at 3 axle center of follower
Side is equipped with round fixinig plate 31, and rule is convexly equipped with several raised lines 32 around in round 31 center of circle of fixinig plate, and sawing machine fuselage 1 is corresponding
3 side of follower is equipped with column 61, and 61 top of column corresponds to 32 side of raised line equipped with speed sensor 62.
Further, the spacing between speed sensor 62 and raised line 32 is 1 to 3cm.
Further, power switch, which is electrically connected, is equipped with relay (not shown).
Further, relay and speed sensor 62 are electrically connected.
Further, 32 quantity of raised line is 1-4 piece, and shape corresponds to each other between raised line 32.
More than, the utility model mechanism is simple, when steel 7 are cut on sawing machine fuselage 1, is moved using raised line 32
The feature synchronous with follower 3 passes through column 61 by the raised line 32 being arranged in 3 side of follower, and in 1 side of sawing machine fuselage
Speed sensor 62 is arranged in corresponding raised line 32, when occurring blocking saw phenomenon, once speed sensor 62 senses raised line 32 no longer
After movement, signal is issued to the relay of sawing machine fuselage 1 immediately and is automatically cut off the power, reach autostop after saw blade card saw, prevent
The only effect of the disconnected saw of saw blade.
Above-described is only the principles of the present invention and preferred embodiment.It should be pointed out that the common skill of this field
For art personnel, without departing from the principle of this utility model, moreover it is possible to make several variations and modifications, also should be regarded as belonging to
In the protection scope of the utility model.
