According to a preferred version of the present utility model, described at least one pair of metering pump be correspondingly 2-8 to metering pump, be for example 8 pairs of metering pumps.In this case, in order to save the space, described 8 pairs of metering pumps are arranged to two-layer up and down, and every layer comprises 4 pairs of metering pumps, and this lead-screw drive mechanism is arranged between this two-layer metering pump.More advantageously, each the two pairs of metering pumps in every layer of 4 pairs of metering pump are arranged symmetrically with respect to lead-screw drive mechanism.Certainly, other arrangement that it may occur to persons skilled in the art that also is encompassed in scope of the present utility model, takes up room as long as can save, and makes the more compact structure of colour mixer.
In the utility model, described leading screw is preferably ball screw, because the surface friction drag of ball screw is less, can further improve sport efficiency and precision.
In addition, metering pump has stock inlet and grout outlet, and in order to be conducive to the exhaust of metering pump, this stock inlet and this grout outlet all are configured to be open upwards.
In the utility model, rotate along different directions by this leading screw of this motor driving, make the piston rod of described metering pump can be with screw seat board linear reciprocating motion, thereby make a metering pump in every pair of metering pump in described at least one pair of metering pump suck mill base from mill base bucket, and another metering pump with mill base from wherein discharging.
The utility model also provides a kind of colour mixer that comprises aforementioned metering pump drive unit.Compare with colour mixer of the prior art, this colour mixer has the characteristics of compact structure.
Description of drawings
Below, by reference to the accompanying drawings to being described in detail according to the metering pump drive unit for colour mixer of the present utility model, wherein:
Fig. 1 is the structural representation according to the metering pump drive unit for colour mixer of the present utility model.
Embodiment
It should be understood by one skilled in the art that content that this paper discusses is only the description to one exemplary embodiment, is not to limit scheme more widely of the present utility model.
In addition, some directivity are described and will be introduced in following description." on ", D score, " level ", etc. directed based on the specific embodiment shown in figure.
Fig. 1 schematically shows an embodiment according to the metering pump drive unit for colour mixer of the present utility model.For the sake of clarity, do not draw out mill base bucket, the mode of communicating of mill base bucket and metering pump is that related domain is common.In the embodiment show in figure 1, colour mixer comprises 8 pairs of metering pumps 2 of horizontal arrangement, correspondingly comprises 8 to (16) mill base bucket, and each mill base bucket is equipped with a corresponding metering pump 2, and every pair of horizontal positioned opposite of metering pump 2.But it will be appreciated by those skilled in the art that, colour mixer also can comprise the metering pump of other suitable number, for example 4 pairs, 6 pairs, 7 pairs, 10 pairs etc., this can determine according to the color category that colour mixer will distribute.
As can be seen from the figure, in this embodiment, the metering pump drive unit comprises drive motor 4 and lead-screw drive mechanism, and this lead-screw drive mechanism comprises screw seat board 10, is arranged on the screw 7 of this screw seat board central position, and the leading screw 4 that extends through this screw 7.The live axle of drive motor 4 links by the end of coupling 6 with leading screw.Advantageously, the 8 pairs of metering pumps 2 are divided on the two-layer pedestal 1 that is installed in colour mixer in up and down, this two-layer metering pump in up and down is arranged symmetrically with respect to lead-screw drive mechanism, and every layer comprise 4 pairs of metering pumps, and these 4 pairs of metering pumps are arranged symmetrically in the both sides of leading screw 4 with respect to lead-screw drive mechanism.The piston rod 3 of each metering pump 2 is connected respectively on screw seat board 10 by piston head draw-bar seat 11, wherein piston rod.It will be appreciated by those skilled in the art that and also can adopt other suitable mechanism that piston rod 3 is connected to screw seat board 10.
Thus one, when drive motor for example rotates along clockwise direction, leading screw 4 rotates screw seat board 10 is for example moved towards the direction away from motor along leading screw, thereby the piston rod 3 of the opposed metering pump of push/pull, make two row's metering pumps 2 near motor 5 suck mill base from separately mill base bucket, and opposed, outpour mill base away from two row's metering pumps 2 of motor.And when drive motor for example rotates in the counterclockwise direction, leading screw 4 rotates screw seat board 10 is for example moved towards the direction near motor along leading screw, thereby the piston rod 3 of the opposed metering pump of push/pull, make two row's metering pumps 2 near motor 5 outpour mill base, and opposed, suck mill base away from two row's metering pumps 2 of motor from separately mill base bucket.
In this model utility, metering pump has stock inlet 9 and grout outlet 12, and in order to be conducive to the exhaust of metering pump, this stock inlet 9 and this grout outlet 12 all are configured to be open upwards
In the utility model, drive motor 5 is for example actuating motor, and leading screw 4 is for example ball screw.But the motor that other is suitable and leading screw also are encompassed in scope of the present utility model.
Be particularly useful for pouring-in colour mixer simultaneously according to drive unit of the present utility model, in this embodiment, injecting simultaneously is not to be that all 16 metering pumps are realized outpouring of mill base simultaneously, and 8 metering pumps that are positioned at the same side are realized injecting simultaneously and outpouring.Advantageously, in the utility model, the grout outlet of metering pump can be connected with the distributing valve of return flow type, metering pump 4 can select whether to outpour mill base as required, if do not need the mill base of certain color, can close the distribution outlet of distributing valve, make the mill base that distributes from metering pump 4 be back to mill base bucket.So, when not needing the mill base of certain color, do not needed piston rod and the lead-screw drive mechanism of corresponding metering pump are disconnected, the piston rod that makes like this is simpler with connecting of lead-screw drive mechanism.
By this drive unit of the present utility model, make the colour mixer that is equipped with this drive unit have compact structure, (especially height space) the less advantage that takes up room, and the power less of the drive motor that uses, cost is lower.
In the situation that do not exceed spirit and scope of the present utility model, those of ordinary skills can make to the utility model these and other change and variation, and this has done in accompanying claims more specifically and has set forth.Be to be further appreciated that, different embodiments' many aspects can completely or partially be replaced mutually.In addition, the explanation that one of ordinary skill in the art will appreciate that the front is only exemplary, can be to the utility model Composition of contents restriction that further describes in accompanying claims.
