Description
Technical field
The utility model relates to woodworking machinery, specifically a kind of abrasive band pendulous device of sander.
Background technology
At present, the abrasive band pendulous device of existing sander generally adopts the contact limit switch to control the abrasive band and swings to the left or to the right, make the abrasive band be in the normal position all the time, to guarantee the sanding quality of sheet material, it comprises upper supporting roller, support, limit switch, cylinder and pneumatic arrangements for speed regulation, the two ends that drive the upper supporting roller that turns round in the abrasive band are through roll shaft, bearing is connected with support, the support lower end is connected with lathe bed through cylinder, support one side is provided with pneumatic arrangements for speed regulation, pneumatic arrangements for speed regulation are connected with cylinder through conduit, the effect of pneumatic arrangements for speed regulation is to utilize control air inflow size to control the time of pendulum band cylinder intake and exhaust, the speed thereby the control upper supporting roller deflects, just controlled the speed of service in abrasive band, limit switch is located at the lower surface at support two ends, limit switch is connected with cylinder through conduit, when sander is worked, when the abrasive band sideslip is run into the contact of left side on (or right side) limit switch, contact passes to cylinder with signal, support is a spot wobble and then the swing of drive abrasive band with cylinder, adjust the position in abrasive band, this device can get a desired effect at the use initial stage, but after long-term the use, because continuous contact, the sensitivity of switch descends gradually, the swing effect that causes the abrasive band worse and worse, finally cause the abrasive band to run band, can only change new limit switch so again and could recover original pendulum band effect, brought trouble for user's processing, reduce production efficiency, increased the lathe cost.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, and the abrasive band pendulous device of the sander of a kind of easy to use, safety, long service life, high efficiency is provided.
The utility model can reach by following measure:
A kind of abrasive band pendulous device of sander, be provided with lathe bed, upper supporting roller, support, cylinder and pneumatic arrangements for speed regulation, it is characterized in that lathe bed one side is provided with limiting photoelectric switch, pendulum band optoelectronic switch, time-delay relay, magnetic valve, brake, the corresponding lathe bed of abrasive band one end is limiting photoelectric switch fixedly, the other end is limiting photoelectric switch and pendulum band optoelectronic switch fixedly, pendulum band optoelectronic switch through tracheae respectively with time-delay relay, magnetic valve, cylinder is connected with pneumatic arrangements for speed regulation, limiting photoelectric switch through tracheae respectively with magnetic valve, cylinder, pneumatic arrangements for speed regulation are connected with brake.
The operation principle of the utility model pendulum band optoelectronic switch: when optoelectronic switch is exposed in the abrasive band, solenoid directional control valve outage in the optoelectronic switch, " A " chamber air inlet of pendulum band cylinder, " B " chamber exhaust, push upper supporting roller to Right deviation, at this moment creep left in the abrasive band, climbs to when covering optoelectronic switch when the abrasive band, and solenoid directional control valve gets, " A " chamber exhaust of cylinder, " B " chamber air inlet is pushed upper supporting roller to "Left"-deviationist, and at this moment creep to the right in the abrasive band, the size of control pendulum band amount, can be by adjusting the time-delay relay of control optoelectronic switch, the abrasive band side-play amount is increased or reduce, go round and begin again in the abrasive band like this puts to drive and does.
The operation principle of the utility model limiting photoelectric switch: control pendulous device at work and deviation in a single day occurs, the abrasive band (or to the right) may occur continuously left and creep, when any any one optoelectronic switch that hides in the limiting photoelectric switch left side (or right) in the upper supporting roller left side (or the right) two abrasive bands, the electrical system control loop cuts off the power supply at once, the sand roller motor cuts off the power supply simultaneously, brake is braked, and charging stops, and need restart lathe after fault is got rid of and process.
The utility model is owing to adopt said structure, has advantages such as easy to use, safety, high efficiency, lathe cost are low, long service life.
