Put, it is simple in construction, from mechanical aspects and electrically aspect to motor and roll up the dual anti-blocking rotation protection of bits machine mechanical part, add and set
Standby service life, security performance are high.
To achieve these goals, the blocking rotation protection device of a kind of volume bits machine provided by the invention, including mechanical protection
Part and electic protection part, the mechanical protection part include sprocket wheel, friction plate, ring flange, power transmission shaft, disk spring and circle
Nut, the electric prospection part include sensing support and sensor, and the sprocket wheel considers electromechanical machine to be worth doing with volume and passes through chain drive, institute
State that sprocket wheel passes sequentially through friction plate, ring flange is mutually driven with power transmission shaft, disk spring is arranged between round nut and ring flange；
Preferably, the sensing support is arranged between disk spring and round nut, and the circumferencial direction for sensing support is set
There is sensing chip；
Preferably, sensor is provided with above the sensing support, lamp is in bright in sensor face sensing chip, is passed
Lamp is in and gone out when between the sensing chip of sensor face two；
Preferably, sensing support, disk spring, round nut and the power transmission shaft are coaxially disposed；
Preferably, the friction plate is provided with two, respectively positioned at sprocket wheel both sides；
Preferably, the ring flange is provided with two, is located at is connected by friction plate with sprocket wheel respectively；
Preferably, the ring flange is connected by flat key with power transmission shaft.
It is provided by the invention, have the advantages that：
1. the size of frictional drive power according to the weight of actual volume bits machine institute Roll Sushi body, can be adjusted by rotating round nut,
Once rolling up bits machine because blocking and stall, the power of stall is more than frictional force, sprocket wheel, left friction plate, right friction plate slipping, volume bits
Machine power transmission shaft does not turn, so as to protect motor and volume bits machine mechanical part.
2. also increase electic protection mode carries out Combined Protection, once Machine guarding failure, can pass through sensor
Sensing support on sensing volume bits machine power transmission shaft, sets sensor sensing signal time-out arbitration functions in motor control program,
When the bright signal of lamp is more than the signal that 1 second or lamp go out and is more than 4 seconds, cut-out volume bits motor power, and then protect motor and
Bits machine mechanical part is rolled up, adds the service life of equipment, security performance is higher.
Brief description of the drawings
Fig. 1 is the structural representation for the blocking rotation protection device that a kind of volume provided by the invention considers machine to be worth doing.
In figure：
1. left 3. left flange plate of friction plate, 4. power transmission shaft, the 5. right right flat key 8. of ring flange 7. of friction plate 6. of sprocket wheel 2.
The round nut 10. of disk spring 9. senses the sensor of support 11..
Embodiment
With reference to specific embodiments and the drawings, the present invention will be further described, to help present disclosure is understood
As shown in figure 1, be a kind of blocking rotation protection device of volume bits machine provided by the invention, including mechanical protection part and
Electic protection part, mechanical protection part include sprocket wheel 1, friction plate 2 and 5, ring flange 3 and 6, power transmission shaft 4, the and of disk spring 8
Round nut 9, electic protection part include sensing support 10 and sensor 11, and volume bits motor is rotated by chain-driving sprocket wheel 1, chain
The right side frictional drive on 1 left side and left friction plate 2, the left side of left friction plate 2 and the right side frictional drive of left flange plate 3 are taken turns, from
And volume bits machine power transmission shaft 4 is driven to rotate；The left side frictional drive of the right side of sprocket wheel 1 and right friction plate 5, the right side of right friction plate 5 with
The left side frictional drive of right ring flange 6, right ring flange 6 drive volume bits machine power transmission shaft 4 to rotate by flat key 7.Disk spring 8 is set
Between round nut 9 and right ring flange 6, disk spring 8 is turned left to be applied to right ring flange 6, right friction plate 5, sprocket wheel 1, left friction plate 2
Add certain pressure, the size of this pressure can change left friction plate 2 and frictional force size, pressure caused by right friction plate 5
Size can be adjusted by the round nut 9 on the screw thread that is set installed in volume bits machine power transmission shaft 4 outer end, if up time
Pin rotates round nut 9, and pressure caused by disk spring 8 increases, and then frictional drive power increases, otherwise reduces.So round nut 9
It can be used for adjusting frictional drive power.If bits machine is rolled up because blocking and stall, when the power of stall is more than frictional force, sprocket wheel 1, a left side
Friction plate 2, the slipping of right friction plate 5, volume bits machine power transmission shaft 4 do not turn, so as to protect motor and volume bits machine mechanical part.
If Machine guarding failure, i.e. sprocket wheel 1, left friction plate 2, right friction plate 5 not slipping, still with transmission
Axle 4 connects.Combined Protection is carried out using another electic protection mode simultaneously, installed between disk spring 8 and round nut 9
One sensing support 10, sensing on support 10 has 6 sensing chips, evenly distributes circumferentially, every 60 degree of sensing chips, is feeling
Answer and a sensor 11 is installed above support, lamp is bright when sensor 11 faces sensing chip, between two sensing chips
Go out, under normal circumstances, when volume bits machine power transmission shaft 4 rotates, sensor 11 goes out 4 seconds, bright 1 second.If bits machine is rolled up because of card
Firmly stall, volume bits machine power transmission shaft 4 is motionless, otherwise the light yellow always of sensor 11, otherwise go out always.Therefore in motor control journey
The induced signal time-out arbitration functions of sensor 11 are set in sequence, when the signal that bright signal is more than 1 second or gone out is more than 4 seconds,
Cut-out volume bits motor power, so as to protect motor and volume bits machine mechanical part.
Specific case used herein is elaborated to inventive concept, and the explanation of above example is only intended to
Help to understand core concept of the invention.It should be pointed out that for those skilled in the art, this is not being departed from
On the premise of inventive concept, any obvious modification, equivalent substitution or other improvement for being made, the present invention should be included in
Protection domain within.
