Description

Wire drawing tension broken wire detection mechanism

Technical Field

The utility model belongs to the technical field of the wire drawing machine production technique and specifically relates to a wire drawing tension broken string detection mechanism.

Background

In the production process of the silk machine, when the broken line occurs, an operator needs to find and manually stop the machine. If the machine cannot be stopped in time, the take-up and pay-off machine cannot brake in time, so that the loose wire arrangement has influence on the surface of the aluminum wire. Meanwhile, the broken wire end can swing when the wire is taken up, and machine parts and operators are damaged.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the existing wire drawing machine in the using process, the utility model provides a wire drawing tension broken wire detection mechanism.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a wire drawing tension broken string detection mechanism, includes the tension bracket, installs the rotation axis of gyro wheel through the bearing on the tension bracket, installs gyro wheel shut down alarm device on the tension bracket.

According to the utility model discloses a further embodiment, further include, shut down alarm device includes the transformer mounting bracket of bolt fastening on the tension bracket lateral wall, has the rotary transformer through the bolt fastening on the transformer mounting bracket, and rotary transformer's transformer axle is connected with the axis of rotation.

According to the utility model discloses a further embodiment includes, the tip of rotation axis has the shaft hole of indent, and in the transformer axle stretched into the shaft hole, round pin axle fastening rotation axis and transformer axle.

According to the utility model discloses a further embodiment, further include, shut down alarm device including fixing the reflection piece in gyro wheel one side, the inboard of tension bracket has the mount through the bolt fastening under the reflection piece, has proximity switch through the bolt fastening on the mount.

The beneficial effects of the utility model are that, this kind of wire drawing tension broken string detection mechanism monitors the operating condition of the gyro wheel on the tension bracket through the device when using, and the gyro wheel stops when the broken string appears, and then judges the condition of broken string, carries out automatic alarm and shuts down, plays critical effect to guarantee safety and product quality.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic structural diagram of an embodiment of the present invention;

in the figure, the device comprises a tension bracket 1, a bearing 2, a bearing 3, a rotating shaft 4, a roller 5, a shaft hole 6, a rotary transformer 7, a transformer shaft 8, a pin shaft 9, a reflecting block 10, a fixing frame 11, a proximity switch 12 and a transformer mounting frame.

Detailed Description

Fig. 1-2 are the structural schematic diagram of the utility model, a wire drawing tension broken string detection mechanism, including tension bracket 1, through the rotation axis 3 of bearing 2 installation gyro wheel 4 on the tension bracket 1, install gyro wheel 4 on the tension bracket 1 and shut down alarm device.

When the wire drawing tension wire breakage detection mechanism is used, the shutdown alarm device on the device gives an alarm when wire breakage occurs, and meanwhile, the shutdown alarm device is connected with a PLC (programmable logic controller) of equipment, and controls the wire drawing machine to shut down when giving an alarm, so that safety and product quality are guaranteed.

According to the utility model discloses a further embodiment, further include, shut down the alarm device and include the transformer mounting bracket 12 of bolt fastening on tension bracket 1 lateral wall, have rotary transformer 6 through the bolt fastening on the transformer mounting bracket 12, and rotary transformer 6's transformer axle 7 is connected with rotation axis 3.

Drive rotary transformer 6 through rotation axis 3 and begin work, rotary transformer can produce the voltage difference at 6 in the pivoted to give PLC with voltage information transfer, when taking place the broken string, gyro wheel 4 will stall, just can not produce the voltage difference on rotary transformer 6, PLC judges the broken string state this moment, and the wire drawing machine of controlling again is shut down the operation, cooperates other buzzer light and so on warning instrument to play the effect of reminding.

According to the utility model discloses a further embodiment includes, the tip of rotation axis 3 has the shaft hole 5 of indent, and in transformer axle 7 stretched into shaft hole 5, the fixed rotation axis 3 of round pin axle 8 and transformer axle 7.

The rapid installation of the rotating shaft 3 and the transformer shaft 7 can be rapidly completed through the pin shaft 8.

According to the utility model discloses a further embodiment, further include, shut down alarm device is including fixing the reflection piece 9 in gyro wheel 4 one side, and the inboard of tension bracket 1 has mount 10 through the bolt fastening under reflection piece 9, has proximity switch 11 through the bolt fastening on mount 10.

When the roller 4 is in normal work, the reflecting block 9 on the roller 4 is periodically close to the proximity switch 11, the proximity switch 11 periodically sends proximity information to the PLC, when the wire break occurs, the roller 4 can rotate under inertia and finally can stop, the wire break state is judged when the proximity information fed back by the proximity switch 11 is greater than 10% of the period, the wire drawing machine is controlled to stop through the PLC, meanwhile, the warning is sent, and the worker can conveniently patrol.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
