The electric driving module 43 of the present invention is the prior art, and is composed of a speed reducer and a motor, wherein the output shaft of the motor is connected with the input shaft of the speed reducer; the third gear 42 is mounted on the output shaft of the reducer.
In the invention, the annular space between the outer stepped cylinder 2 and the inner stepped cylinder 4 corresponds to the annular space between the rotary cylinder 25 and the first rotary ring block 30, so that the powder coating leaked from the annular space between the rotary cylinder 25 and the first rotary ring block 30 directly falls between the outer stepped cylinder 2 and the inner stepped cylinder 4 and is filled into a packaging bag positioned below the outer stepped cylinder 2 and the inner stepped cylinder 4.
The differential mechanism 13 of the present invention works on the same principle as the differential mechanism of an automobile, and the first output shaft 55, the second output shaft 53 and the differential input shaft 57 of the differential mechanism 13 correspond to two output half shafts and a driving input shaft of the automobile differential mechanism.
The working process of the invention is as follows: in the initial state, the first trapezoidal guide block 41 is located at the bottom of the corresponding trapezoidal guide groove 10, the second trapezoidal guide block 36 is located at the top of the corresponding trapezoidal guide groove 10, the distance between the first trapezoidal guide block 41 and the top of the corresponding trapezoidal guide groove 10 is equal to the distance between the second trapezoidal guide block 36 and the bottom of the corresponding trapezoidal guide groove 10, one end of the limiting block 18 with the inclined surface is located in the first limiting groove 21 on the limiting wheel 20, the through hole at the center of the rotary circular block 32 is blocked by the plug to prevent the powder coating from leaking out of the through hole, and the spring of the limiting block 18 is in a pre-compression state.
For the grinding of the blocky powder coating, a conveying and grinding device in the prior art is adopted, and the ground powder coating particles are conveyed into a hopper 58; the hopper 58 of the present invention may be mounted on existing feed grinding apparatus.
When powder coating needs to be screened and packaged, the power is switched on to enable the conveying and grinding device to start grinding, the electric driving module 43 drives the third gear 42 to rotate after the power is switched on, the third gear 42 drives the rotary cylinder 25 to rotate along the annular groove 3 on the outer stepped cylinder 2 through the toothed ring 26, and the rotary cylinder 25 drives the first rotary ring block 30, the second rotary ring block 31 and the rotary circular block 32 to synchronously rotate through the first connecting plate 28 and the second connecting plate 29.
Then the powder coating falls onto the rotary round block 32 which is positioned in the fine screen cylinder 33 and continuously rotates from the hopper 58, under the action of centrifugal force, the powder coating falling onto the rotary round block 32 moves to the periphery of the rotary round block 32 and is blocked by the fine screen cylinder 33, and the fine screen groove 34 on the fine screen cylinder 33 leaks the powder coating smaller than the width size of the powder coating; under the continuous action of centrifugal force, the powder coating leaked from the fine screen cylinder 33 falls into a space between the inner stepped cylinder 4 and the outer stepped cylinder 2 from an annular gap between the first rotating ring block 30 and the rotating cylinder 25, and falls into a packaging bag sleeved at the lower end of the outer stepped cylinder 2 from a space between the inner stepped cylinder 4 and the outer stepped cylinder 2; powder coating is continuously added into the fine screen cylinder 33, and under the action of centrifugal force, the fine powder coating leaks through the fine screen groove 34 on the fine screen cylinder 33 and falls into a packaging bag sleeved at the lower end of the outer stepped cylinder 2 through the annular gap between the first rotating ring block 30 and the rotating cylinder 25 and the space between the inner stepped cylinder 4 and the outer stepped cylinder 2.
When the fine particle powder coating is basically screened and the thicker powder coating which cannot be leaked out in the fine screen drum 33 is accumulated to a certain amount, the self-locking motor 22 is controlled to start rotating through the remote control system, and the self-locking motor 22 drives the first gear 56 to rotate through the differential input shaft 57 on the differential mechanism 13; since the limit wheel 20 is limited by the limit block 18, the second gear 14 mounted on the second output shaft 53 does not rotate, and the power output by the self-locking motor 22 is transmitted to the second gear 14 engaged with the first rack 40 through the first gear 56, the gear barrel 51, the first bevel gear 54, the corresponding second bevel gear 52 and the first output shaft 55; the second gear 14 drives the first rack 40 to move upwards along the corresponding trapezoidal guide groove 10; the first rack 40 drives the coarse screen cylinder 38 to move upwards synchronously; when the first trapezoidal guide block 41 moves upwards along the corresponding trapezoidal guide groove 10 to the limit position, the first rack 40 and the coarse screen cylinder 38 stop moving under the limit of the trapezoidal guide groove 10; the whole power output from the self-locking motor 22 is transmitted to the second gear 14 meshed with the second rack 35 through the first gear 56, the gear barrel 51, the first bevel gear 54, the corresponding second bevel gear 52 and the second output shaft 53 in sequence; the second gear 14 drives the limiting wheel 20 to act on the upper inclined plane of the limiting block 18 through the second output shaft 53, so that the limiting block 18 is retracted inwards along the second limiting groove 17, the limiting spring 19 is compressed, the limiting block 18 removes the rotation limitation on the limiting wheel 20, the second gear 14 drives the second rack 35 to move downwards along the corresponding trapezoidal guide groove 10, the differential spring 37 is compressed, and the second rack 35 drives the fine screen cylinder 33 to move downwards synchronously; in the process of moving the fine screen drum 33 downwards, the powder coating left after being screened by the fine screen drum 33 loses the blockage of the fine screen drum 33 and moves towards the raised coarse screen drum 38 under the action of centrifugal force; when the fine screen cylinder 33 moves downwards to the limit, the limiting block 18 just enters the first limiting groove 21 on the limiting wheel 20 again, and the limiting block 18 limits the limiting wheel 20 again; and then the self-locking motor 22 is controlled to stop running, the motor shaft is self-locked, further the gear in the differential mechanism 13 does not rotate any more, finally the first rack 40 and the second rack 35 do not move any more, all the residual powder coating in the fine screen drum 33 moves to the coarse screen drum 38 under the action of centrifugal force, and a part of the residual powder coating moves to the rotary drum 25 through the coarse screen groove 39 on the coarse screen drum 38 and falls into the space between the inner stepped drum 4 and the outer stepped drum 2 from the annular gap between the first rotary ring block 30 and the rotary drum 25, and then falls into an empty packaging bag sleeved at the lower end of the outer stepped drum 2 from the space between the inner stepped drum 4 and the outer stepped drum 2.
When the powder coating in the coarse screen cylinder 38 can be completely screened out by the powder coating passing through the coarse screen groove 39, the particle size of the remaining powder coating is maximum; then the power supply is cut off to stop the operation of the electric driving module 43, and the rotary cylinder 25, the first rotary ring block 30, the second rotary ring block 31 and the rotary round block 32 stop rotating; the plug for blocking the through hole of the rotary round block 32 is taken off, and the residual powder coating in the coarse screen cylinder 38 falls into a new packaging belt sleeved at the lower end of the outer stepped cylinder 2 from the through hole of the rotary round block 32 through the discharging pipe 45 and the discharging hole 6 on the circular plate 5 of the base.
When the residual powder coating after sieving in the coarse sieving drum 38 is cleaned up, the self-locking motor 22 is controlled to rotate reversely by the control system, and the self-locking motor 22 drives the first gear 56 to rotate reversely through the differential input shaft 57; since the stopper wheel 20 is restricted by the stopper 18, the rotation of the second gear 14 coaxial with the stopper wheel 20 is restricted, and the second gear 14 on the first output shaft 55 is not restricted at this time; the first gear 56 is driven by the gear barrel 51, the first bevel gear 54 and the second bevel gear 52 to rotate reversely with the second gear 14 on the first output shaft 55, and the second gear 14 drives the coarse screen cylinder 38 to move downwards synchronously through the first rack 40; when the first rack 40 drives the coarse screen drum 38 to move downwards to the limit position, the trapezoidal guide groove 10 matched with the first trapezoidal guide block 41 on the first rack 40 forms a new limit to the rotation of the second gear 14 on the first output shaft 55; at this time, the first gear 56 which continuously rotates reversely under the driving of the reverse self-locking motor 22 drives the second gear 14 installed on the second output shaft 53 to rotate reversely through the gear barrel 51, the first bevel gear 54 and the second bevel gear 52, the limiting wheel 20 overcomes the limitation of the limiting block 18 to rotate, the second gear 14 on the second output shaft 53 drives the fine screen cylinder 33 to move synchronously upwards through the second rack 35, and the differential spring 37 releases energy; when the second rack 35 drives the fine screen cylinder 33 to move upwards synchronously to the initial position, the differential spring 37 restores to the original state, and the limiting block 18 enters the first limiting groove 21 on the limiting wheel 20 again to form new limiting on the limiting wheel 20; and then the self-locking motor 22 is controlled by the control system to stop running, and the screening of the powder coating is finished.
In conclusion, the invention has the beneficial effects that: the powder coating packaging machine can realize the screening of powder coatings from the hopper 58 by the fine screen cylinder 33 and the coarse screen cylinder 38 which are lifted alternately, the powder coatings mixed by the large particles and the small particles from the hopper 58 are classified by coarse and fine screening, and the screened powder coatings with different sizes are filled into different packaging bags, so the coating screening efficiency is improved; the traditional powder coating screening equipment needs to realize alternate lifting between the fine screen cylinder 33 and the coarse screen cylinder 38 through alternate work of two motors, but the powder coating packaging machine in the invention can respectively drive the coarse screen cylinder 38 and the fine screen cylinder 33 to alternately lift through the first rack 40 and the second rack 35 only through one self-locking motor 22, so as to realize automatic screening of powder coating, thereby reducing the production cost of the equipment, simplifying the control system of the motors and enabling the equipment to be operated more easily.
