Description
Technical field
The utility model relates to a kind of particulate matter measuring pump.
Background technology
At present, most of packing operation is by artificial direct control, in packing material pouring volume cup, because the human element of outwardness, the problem of the inaccurate and packing finite volume of packing dosage must appear, and exist simultaneously and divide process of assembling loaded down with trivial details, waste time and energy shortcoming such as efficient is low.Some dispensing apparatus have also appearred on the market, its shortcoming complex structure, and the packing precision is low, and the packing effect is undesirable.
The utility model content
The purpose of this utility model is that a kind of simple in structure, particulate matter measuring pump that the packing precision is high is provided in order to solve the problems of the technologies described above.
To achieve these goals, the utility model is by the following technical solutions:
A kind of particulate matter measuring pump, it comprises: the output shaft of motor, housing and packing wheel, described motor is connected driving packing wheel, even spacer ring is provided with some capaciting material grooves on the outer circumference surface of this packing wheel, this packing wheel is installed with in described housing cavity, this packing wheel chamber section coupling cooresponding with it coincide, this housing upper end is provided with the feeding-passage that is communicated with described packing wheel, is provided with the vertical tapping channel that is communicated with this packing wheel bottom in the bottom surface of housing.
Described motor is a stepping motor.
Described feeding-passage is communicated with the highest point of described packing wheel, and it is vertical shape.
The diameter dimension of described feeding-passage is consistent with the width of described packing wheel capaciting material groove.
Circular clearance between described packing wheel and the described housing cavity inwall is less than the material size of institute's packing.
Described packing wheel is for being installed in the gear in the rotating shaft, and the output shaft of described motor is connected with an end of this rotating shaft.
The beneficial effects of the utility model: the resulting particulate matter measuring pump of the utility model, it is simple in structure, has reduced human element greatly and has carried out the error that packing brings, and has improved packing precision and packing efficient greatly.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model particulate matter measuring pump;
Fig. 2 be among Fig. 1 A-A to structural representation.
The specific embodiment
A kind of particulate matter measuring pump, it comprises: the output shaft of motor, housing and packing wheel, motor is connected driving packing wheel, even spacer ring is provided with some capaciting material grooves on the outer circumference surface of packing wheel, the packing wheel is installed with in housing cavity, packing wheel chamber section coupling cooresponding with it coincide, the housing upper end is provided with the feeding-passage that is communicated with the packing wheel, is provided with the vertical tapping channel that is communicated with packing wheel bottom in the bottom surface of housing.
As depicted in figs. 1 and 2, the specific embodiment of the utility model particulate matter measuring pump, it comprises: motor 1, housing 2 and packing wheel 3.Motor 1 is a stepping motor.Housing 2 is provided with a chamber 21, and this chamber 21 is one to run through ladder hole.The outside wall surface of packing wheel 3 is provided with some capaciting material grooves along the even spacer ring of circumferencial direction, and each capaciting material groove scantling of structure is identical.Packing wheel 3 is one to be installed in the gear 32 in the rotating shaft 31.Motor 1 output shaft drives rotating shaft 31 driven gears 32 and rotates.This chamber 21 has one section chamber section of coincideing with gear 32 profiles coupling, and this chamber section is cylindrical.Top and bottom at housing 2 are respectively equipped with feeding-passage 22 and the tapping channel 23 that is communicated with the teeth groove of gear 32, and feeding-passage 22 aligns with the vertex of gear 32 and is communicated with, and tapping channel 23 aligns with the nadir of gear and is communicated with.In the rotating shaft 31 of gear 32 both sides, be arranged with bearing 4, be respectively equipped with catch 5 at the two ends of gear 32, this catch 5 is set in the rotating shaft 31, does not rotate with rotating shaft 31, the outer ring of this catch 5 and housing 2 chamber walls are close to, and prevent that the aliquot materials flow from going out the teeth groove of gear 32.Between catch 5 and bearing 4, be provided with and support securing device 6, be used for firm bearing and catch, prevent its play.Be installed with bearing cap shim 7a, 7b at the two ends of housing 1.
The chamber section of gear and its coupling is the axis hole free-running fit.Circular clearance between gear teeth tips and its corresponding shell chamber inner wall should determine that its circular clearance is less than the material outside dimension of institute's packing according to the size of packing material, prevents to reveal and be stuck between chamber wall and the tooth top wall.Annular gaps is greater than 0, and it prevents to contact wall and produces friction.
The length direction of feeding-passage is that the length direction along gear tooth slot is the length direction that the axis direction of gear is called feeding-passage, and the Width of feeding-passage is the Width that is called feeding-passage along the circumferencial direction of gear.The length dimension of feeding-passage is not more than the length dimension of gear tooth slot.The feeding-passage length dimension is consistent with the length dimension of gear tooth slot in the present embodiment.The width dimensions of feeding-passage is at least greater than the width dimensions of a gear tooth slot.The consistent size of feeding-passage and tapping channel, top and bottom that it is separately positioned on housing are 180 ° of settings up and down.
The packing explanation: particulate matter relies on deadweight to flow into packing wheel capaciting material groove by feeding-passage, and fills with capaciting material groove.Along with the rotation of packing wheel, particulate matter flows into sub-bottling by tapping channel, and a packing what just put the volumetric flask of much capacity, configures the branch loading amount, and the packing wheel can stop automatically.
More than be preferred embodiment of the present utility model and design graphic; above-mentioned preferred embodiment and to design graphic only be casehistory; be not to be used to limit interest field of the present utility model; all with equalization technological means or be the interest field that contained of the application's claim and the implementer does not all break away from protection domain of the present utility model.
