Abstract
A liquid jetter consists of a cylindrical cylinder, internal gears and external gears. The inner wall of the cylinder allocates with external gears. An internal gear is arranged in the cylinder, the axial direction of the internal gear is parallel with the cylinder's, the internal gear can engage with the external gear completely, its diameter is less than the cylinder's, and its rotation center diverges from the center of the cylinder. The cylinder is provided radially with two channels which are crossed but mutually non-parallel. Because the engage movement is continuous, accordingly, the liquid can be jetted out continuously. Because the teeth shape of the gears is fixed, accordingly, the jetting quantity of the liquid is stable. Because the engage movements of the gears are smooth, accordingly, they are uneasy to be abraded and the failure rate is small. The apparatus is suitable for the oil varnish, the color, the printing ink and other similar thick liquid.
Description
Technical field
The present invention relates to a kind of liquid distributor that is used for dispensing viscous liquid and measures its volume.
Background technique
In traditional toning equipment, the function of metering liquid volume is to realize by the reciprocating pump in the distributor.It outpours liquid by the to-and-fro motion of piston, simultaneously by the dial metered volume on the reciprocating pump outer wall.Its shortcoming is to outpour continuously, measure inaccurate, and easily wearing and tearing.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing liquid dispensing apparatus can not outpour, measure shortcomings such as inaccurate, easy wearing and tearing continuously.
The present invention discloses a kind of liquid dispensing apparatus for this reason, and it is made up of cylinder block, internal gear and external gear, is distributed with external gear on inboard wall of cylinder block; An internal gear is arranged in cylinder body, its axial and cylinder body parallel to an axis, this internal gear can mesh fully with the aforementioned external teeth wheel, and its diameter is less than cylinder diameter, and its rotating center departs from the center of cylinder body; Radially be provided with passage 2 intersections, that be not parallel to each other at cylinder body.
Because gear motion is continuous, therefore make liquid to outpour continuously.
Because tooth-formation of gear fixes, so the amount of outpouring of liquid depends on the rotating speed of gear, promptly can determine the amount of outpouring of liquid by the rotating speed that reads gear.
Because gear meshing motion is mild, do not resemble and can produce bigger impact force the reciprocating pump, therefore not easy to wear, rate of fault is little.
This device is applicable to paint, pigment, printing ink and other similar thick liquid.
Description of drawings
Figure is the structural representation that liquid described in the utility model outpours device;
Wherein, 1. cylinder body, 2. external gear, 3. internal gear, 4 liquid gateways
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
As shown in drawings, liquid described in the utility model outpours device to be made up of cylinder block 1, external gear 2 and internal gear 3, is distributed with external gear 2 on the inwall of cylinder body 1; An internal gear 3 is arranged in cylinder body 1, its axial and cylinder body parallel to an axis, this internal gear 3 can be taken turns 2 engagements fully with aforementioned external teeth, and its diameter is less than cylinder diameter, and its rotating center departs from the center of cylinder body; At radially being provided with of cylinder body 1 passage 2 intersections, that be not parallel to each other, promptly the liquid gateway 4.
During work, internal gear 3 is subjected to the driving of drive unit, and its center moves in a circle around the center of cylinder body 1, and internal gear 3 and external gear 2 engagements form malleation, thereby the liquid extrusion is gone when two gears enter engagement; When two gears leave engagement, form negative pressure, thereby draws fluid is come.And so forth, can make liquid constantly be sucked into and come, be forced out immediately again, thereby realized uninterruptedly outpouring of liquid.
