Detailed Description

The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.

As shown in fig. 1-9, an automatic batching device for powder coating production structurally comprises a conveying belt 11, a conveying frame 12 and a material box 13, and further comprises an open-pore top plate unit 1 arranged on the conveying frame 12 and positioned above the conveying belt 11, a bending pipe unit 2 which is inserted and arranged on the open-pore top plate unit 1 and used for connecting a material cylinder, a lifting plate unit 3 arranged on the upper surface of the open-pore top plate unit 1, and a stirring motor unit 4 which is arranged on the lower surface of the lifting plate unit 3, inserted and connected with the open-pore top plate unit 1 and used for carrying out a material mixing operation in the material box 13.

In this embodiment, a plurality of the material boxes 13 are all placed on the conveyor belt 11, sequentially pass through the position below the stirring motor unit 4 and are suspended, during the suspension period, the bending pipe unit 2 firstly drops all the raw materials for producing the powder coating, then the stirring motor unit 4 is further below and is started, after the stirring and mixing are completed, the stirring motor unit 4 is further lifted upwards and separated, finally the material box 13 is removed, and the next empty material box 13 is continued.

Wherein the lifting plate unit 3 provides a lifting function for the stirring motor unit 4, otherwise the bin 13 is blocked by the stirring motor unit 4 before coming under the stirring motor unit 4 or when the bin 13 needs to be removed.

In addition, according to the mode of prior art above the buckling pipe unit 2, a feed cylinder and a valve are matched, so that various raw materials of the powder coating can fall down as required.

Finally, the stirring motor unit 4 may not need to be turned on, i.e. the mixing degree is sufficient in the process of the raw materials falling into the material box 13, or the subsequent melt extrusion equipment has sufficient mixing function, and the stirring motor unit 4 always keeps high and does not contact with the material box 13.

The perforated top plate unit 1 comprises an upright post 101 arranged on the conveying frame 12, a rectangular transverse plate 102 arranged on the upper end surface of the upright post 101, a round hole 103 arranged on the rectangular transverse plate 102 and used for being inserted and fixed with the bent pipe unit 2, and a central hole 104 arranged on the rectangular transverse plate 102 and used for being inserted and penetrated through the stirring motor unit 4.

In this embodiment, the upright posts 101 may be disposed on one side or both sides, so as to ensure that the rectangular cross plate 102 is still stable after mainly loading the weight of the stirring motor unit 4, where the above-mentioned charging barrel is provided with a fixing structure, and the weight of the charging barrel is not pressed on the rectangular cross plate 102.

Furthermore, the circular hole 103 is required to clamp the bent pipe unit 2, ensuring that the latter is not easily dropped and is not easily shaken, whereas the central hole 104 is just opposite and cannot clamp the stirring motor unit 4, since the latter requires relatively frequent lifting adjustments.

The number of the round holes 103 is 3-5.

In this embodiment, the number of the bending tube units 2 is 3-5, which corresponds to the same number of barrels. In other words, if the powder coating requires a substantial excess of raw material types, the dosing operation may be performed by a plurality of the automated dosing devices in sequence, one after the other.

The perforated top plate unit 1 further comprises a lateral U-shaped plate 105 which is arranged on the lower end face of the upright post 101 and is clamped with the conveying frame 12, and a sealing side plate 106 which is arranged on the lateral U-shaped plate 105 and is used for clamping the conveying frame 12.

In this embodiment, the sealing side plates 106 are fixed on the lateral U-shaped plates 105 by means of fastening bolts, that is, the carriage 12 is clamped at the same time, so that the whole perforated top plate unit 1 is not easy to fall off and slide on the carriage 12, otherwise, the material box 13 may be difficult to align with the stirring motor unit 4, or the pipe on the material cylinder is bent and broken.

The bending pipe unit 2 comprises a vertical fixing pipe 201 arranged on the round hole 103 and a bending pipe 202 arranged at the pipe orifice of the lower end of the vertical fixing pipe 201 and with a discharge hole facing one side of the stirring motor unit 4.

In this embodiment, the plurality of bending pipes 202 face the stirring motor unit 4, so that the raw materials fall to a good degree of uniformity. In other words, all the circular holes 103 are uniformly spaced apart in a circumferential arrangement on the side of the central hole 104.

Finally, the upper end of the vertical fixing pipe 201 is connected with a blanking pipe of the charging barrel, and an adjusting valve can be arranged on the blanking pipe.

The lifter plate unit 3 includes an air cylinder 301 provided on the upper surface of the rectangular cross plate 102, and a lifter plate 302 provided on the air cylinder 301 and used for mounting the agitator motor unit 4.

In this embodiment, the stroke of the cylinder 301 needs to be relatively large, so as to ensure that the lowest point of the stirring motor unit 4 can fully and properly extend into the bin 13, and that the highest point of the stirring motor unit 4 can completely leave the moving space of the bin 13 and cannot collide with the bin 13.

Further, the number of the cylinders 301 is 2, and the cylinders are disposed on the side plate of the center hole 104, and do not collide with the vertical fixing pipe 201.

The stirring motor unit 4 includes a vertical extension rod 401 provided on the lower surface of the lifting plate 302 and inserted into the central hole 104, a gear motor 402 provided on the lower end surface of the vertical extension rod 401, and stirring blades 403 provided on the gear motor 402.

In this embodiment, the lowest point of the stirring motor unit 4 is that the air cylinder 301 is fully retracted, the highest point is that the stirring blade 403 just touches the lower surface of the rectangular cross plate 102, and at this time, if the reducing motor 402 is directly mounted on the lower surface of the lifting plate 302, the lifting amplitude is small, and the stirring blade 403 is completely impossible to enter the bin 13. This is thus the effect of the vertical extension bar 401.

In addition, the rotation speed of the stirring blade 403 is several tens of revolutions per minute, and the paint raw material a is not required to be thrown out too fast, otherwise.

On the lower surface of the rectangular cross plate 102, a carriage unit 5 for vertically supporting the speed reduction motor 402 in an idle state is further provided.

In this embodiment, when the coating raw material a can be mixed to a desired uniformity by only falling, the carriage unit 5 needs to be turned on to support the gear motor 402, so that the gear motor is always at a high level, and at this time, the air supply system on the air cylinder 301 can be deactivated, so as to achieve a relatively energy-saving effect.

The carriage unit 5 includes an arc-shaped support plate 501 provided on the lower surface of the inverted gear motor 402, a socket rod 502 provided on the arc-shaped support plate 501, and a hole plate 503 provided on the lower surface of the rectangular cross plate 102 for inserting and fixing the socket rod 502.

In this embodiment, the arc-shaped support plate 501 and the plugging rod 502 are a single body which can slide only on the orifice plate 503 to the left and right, and cannot rotate. When the stirring motor unit 4 needs to be started up and down, the arc-shaped supporting plate 501 is always positioned at the side far away from the gear motor 402.

When the stirring motor unit 4 is not needed, the gear motor 402 is pulled to the highest point, then the arc-shaped supporting plate 501 slides to the lower part of the gear motor 402, and finally the air cylinder 301 is slowly lowered until the arc-shaped supporting plate 501 can support and limit the gear motor 402, and at the moment, the air cylinder 301 can be closed.

In this process, the carriage unit 5, by virtue of its structural rigidity, ensures that the gear motor 402 together with the stirring blade 403 is always in a relatively high position, i.e. the stirring blade 403 is above the upper surface of the bin 13.

The carriage unit 5 further includes a snap ring 504 disposed on the insertion rod 502 and configured to block and limit the lateral extension length of the arc-shaped support plate 501.

In this embodiment, the vertical cross-section of the plugging rod 502 is square, and the material of the clamping ring 504 is common rubber, which has at least two functions: 1. the push-pull action of the plug rod 502 is more comfortable, and the clamping ring 504 is a holding handle; 2. the arc-shaped supporting plate 501 is prevented from being excessively extended, otherwise, the motor shaft of the gear motor 402 is prevented from being bumped or damaged.

Therefore, the snap ring 504 needs to be tightened on the insertion rod 502, and no relative sliding can occur.

Finally, the advantages of the automated batching plant in this embodiment are summarized below.

First, lifter plate unit 3 provides a lift function for the stirring mixing operation of agitator motor unit 4, and then makes continuous movement mode of conveyer belt 11 and workbin 13 be suitable for, and agitator motor unit 4 can not collide with workbin 13 promptly, and finally whole batching operation is full automatization, and efficiency is higher.

And the whole installation structure of the bending material pipe unit 2 and the stirring motor unit 4 is high in stability, and the continuous material proportioning device is suitable for continuous material proportioning on a conveyor.

Thirdly, the discharge gate of buckling material pipe unit 2 is whole inwards, and concentrate the unloading in a department, consequently make all kinds of raw materials just have certain degree of mixing when the whereabouts, alleviate agitator motor unit 4's work load, can even need not agitator motor unit 4, and then need not lifter plate unit 3 finally realizes more suitable, energy-conserving batching operation effect.

Fourth, the stirring motor unit 4 has a vertical lifting effect that is not easy to deflect left and right, so as to ensure that the stirring blade 403 can sufficiently and properly stir various raw materials.

Fifthly, when the stirring motor unit 4 is idle and the lifting plate unit 3 is closed, the sliding frame unit 5 can fully support and fix the stirring motor unit 4, so that the stirring blades 403 are prevented from colliding with the feed box 13, and the flexible, selectable, safe and stable stirring function of the batching equipment is ensured.

Sixth, the carriage unit 5 is in a retracted state when not in use, and the lifting effect of the stirring motor unit 4 is not affected or interfered.
