When the brush is in work, a power supply is switched on, a switch is switched on, the motor 4 drives the driving gear 2 to rotate, the driving gear 2 drives the worm gear 9 to rotate, the worm gear 9 drives the rotating shaft 10 to rotate, the brush head 7 continuously rotates under the action of the rotating shaft 10, meanwhile, the driving gear 2 drives the driven gear 5 to rotate, the cylindrical cam 6 also starts to rotate under the action of the driven gear 5, due to the rotation of the cylindrical cam 6, the roller 15 which is in contact with the cylindrical cam 6 moves linearly along the oval barrel wall of the cylindrical cam 6, and the linkage plate 8 also moves linearly relative to the guide rod 12. When the roller 15 is at the second level 63, the spring 13 is in a normal state, and when the roller 15 moves to the first level 61 along the oval barrel wall of the cylindrical boss 6 in a relative motion manner, the linkage plate 8 moves to the farthest position on the guide rod 12, the boss 24 moves to the farthest position in the I-shaped clamping groove 25, and the spring 13 is in a stretched state; when the roller 15 moves to the second level 63 along the first level 61 of the elliptic barrel wall of the cylindrical cam 6, the linkage plate 8 moves to the initial position on the guide rod 12, the I-shaped clamping groove 25 moves to the initial position, and the spring 13 returns to the normal state, so that the brush head 7 is driven to reciprocate in cycles. When brushing glue, the glue enters the inside of the rotating shaft 10 through the rubber tube 21 and reaches the glue outlet 73 along the inside of the rotating shaft 10, the rubber tube 21 only follows the boss 24 to do linear motion, when the roller 15 is positioned at the first level 61 and the second level 63 of the oval barrel wall of the cylindrical cam 6, the glue outlet operation is started, the glue is discharged through the glue outlet 73 on the brush head 7, the brush bristles 72 perform the glue brushing operation on the part, and the brush head 7 rotates and moves back and forth simultaneously, so that the glue can be uniformly brushed on the surface of the part. Further, since the speed of the brush head 7 is continuously reduced due to the resistance of the spring due to the tension when the roller 15 moves to the first level 61 along the oval barrel wall of the cylindrical boss 6 in a relative motion, the rotational speed of the motor can be increased so that the speed is maintained in a constant state; when the roller 15 moves to the second level 63 along the first level 61 of the elliptic barrel wall of the cylindrical cam 6 in a relative motion, the speed of the brush head 7 is continuously increased due to the tension action of the spring, so that the rotating speed of the motor can be reduced, the speed is kept at the same speed, the speed of the brush head 7 is kept constant when the brush head reciprocates, and the effect of uniform and efficient glue brushing can be achieved. Furthermore, the bristles 72 are arranged in a spiral distribution, and since the glue is discharged from the glue outlet 73 in the middle of the brush head 7, the glue is thrown outwards due to the centrifugal force when the brush head 7 rotates, and the spiral brush head can enable the glue to diffuse outwards gradually, so that the uniformity of the brush glue is improved.
The reciprocating uniform glue brushing device has the following advantages: utilize the motor to drive inside gear and cylindrical cam mechanism and form reciprocating structure to drive the brush mucilage binding and put and carry out reciprocating motion, improve the even effect of brushing gluey, also can brush simultaneously to a plurality of parts and glue, improve the efficiency of brushing gluey, further keep reciprocating motion at invariable speed, can reach the even effect of brushing gluey high-efficient. Further, set the brush hair to the spiral and distribute, because glue is from the mouth of gluing and spit out in the middle of the brush head, can glue outwards to get rid of because of the effect of centrifugal force when the brush head is rotatory, spiral helicine brush head can let glue outwards diffusion gradually to improve the homogeneity that the brush was glued, and owing to set up the setting of brush head brush hair, can brush to the product of different shapes or spare part and glue, application scope is wider, the brush head is in the state of working always simultaneously, avoided empty out of work, practiced thrift the energy.
