Abstract
The invention provides a lead screw rotation type all-electric double-component metering pump which comprises a driving mechanism, a pump body (3), a material pipe (15) and a static material mixer (16); a feed opening on the lower end of the pump body is in contact with a component A (1) and a component B (2) in a charging basket through a pressing plate (17); a pump body shaft (4) is connected with a ball screw nut (7) through a connecting sleeve (5), and the upper part of a ball screw shaft (8) is connected with a precise planetary gearbox (11) through a bearing seat (9); a stretching shaft of a servo motor (12) is connected with the precise planetary gearbox (11); an upper cross slab (10) for fixing the bearing seat, a lower cross slab (14) for fixing the pump body and a sliding plate (6) at the middle part are parallel to each other, and shared guide posts (13) used as connecting rods are respectively arranged at the left sides and the right sides of the upper cross slab (10), the lower cross slab (14) and the sliding plate (6). Compared with a hydraulic driven metering pump, the invention has the advantages of high precision in controlling the rotating speed material distribution proportion, capability of burdening according to any proportion, precise and stable discharging quantity, energy saving and no noise.
Description
Technical field
The present invention relates to the metering supply device in a kind of liquid rubber moulding production procedure, is the measuring pump that adopts motor and ball screw assembly, to drive.
Background technology
At present; The measuring pump that is adopted in the liquid rubber moulding production process all relies on hydraulic-driven, two oil cylinder series systems both at home and abroad; 200610149060.5 " liquid silica gel interlocked injection method and the devices " that the applicant has authorized also belong to hydraulic-driven, two oil cylinder or heavy wool cylinder interlock mode.With hydraulically powered pair of component measuring pump, the mixed ratio of two kinds of components is fixed, and exists than large deviation; To the compensation of deviation difficulty, hydraulic system is bulky, easy oil leakage, pipeline is many, service life is not satisfactory, and power consumption greatly; Noise is arranged, few for a long time unstable during discharging.
Summary of the invention
The technical problem that the present invention will solve is to design the rotary all-electric two component measuring pumps of a kind of leading screw.
Solving this technical problem the technical scheme that is adopted is: the rotary all-electric pair of component measuring pump of this leading screw; Comprise driving mechanism; The pump housing; Material pipe and static blender; The charging aperture of pump housing lower end contacts with A component or B component in the charging basket through pressing plate; Pump housing beam warp adapter sleeve links to each other with ball-screw nut; Ball-screw top links to each other with accurate planetary reduction box through bearing block; The servomotor projecting shaft connects accurate row amount reduction box; The upper cross plate of fixed bearing block; Fixedly the lower cross plate of the pump housing and slide plate placed in the middle are parallel to each other, and three's left and right sides respectively has the guide pillar of common double as connecting rod.
The said pump housing is the volume type measuring pump pump housing.
The invention has the beneficial effects as follows and adopt servomotor, accurate planetary reduction box and ball screw assembly, is used as power and transmission mechanism; Machine volume is little, pipeline is few, long service life; The precision of control rotating speed is high; The adapted system controlled by computer; Place A, B two components of two charging baskets to mix respectively by arbitrary proportion; Feeding speed and feed pressure accurate and adjustable, energy-conservation, noiselessness.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The practical implementation method
The present invention details below in conjunction with embodiment and with reference to accompanying drawing: shown in the accompanying drawing; The rotary all-electric pair of component measuring pump of this leading screw; Comprise driving mechanism; The pump housing 3; Material pipe 15 and static blender 16; The charging aperture of pump housing lower end contacts with A component 1 or B component 2 in the charging basket through pressing plate 17; Pump housing axle 4 links to each other with ball-screw nut 7 through adapter sleeve 5; Ballscrew shaft 8 tops link to each other with accurate planetary reduction box 11 through bearing block 9; Servomotor 12 projecting shafts connect accurate planetary reduction box 11; The upper cross plate 10 of fixed bearing block; Fixedly the lower cross plate 14 of the pump housing is parallel to each other with slide plate 6 placed in the middle, and three's left and right sides respectively has the guide pillar 13 of common double as connecting rod.The present invention adopts the volume type measuring pump, and the said pump housing 3 is the volume type measuring pump pump housing.What accompanying drawing showed is the measuring pump that two components mix, if need three components to mix, then increases the identical cell arrangement of a cover again; Connect corresponding material pipe and C charging basket and get final product, (charging basket is used to hold the each component material, and this material is buied from factory); The rest may be inferred by analogy, until many components measuring pump.During work; Start servomotor 12; Press rotating speed and proportion scale running that microcomputer is set; The positive and negative rotation of servomotor drives ballscrew shaft 8 positive and negative rotations, and slide plate 6 goes up and down according to the stroke of setting repeatedly; Pulling pump housing axle 4 is with charging basket A component 1 and B component 2; Ratio in setting is extracted out, and exports from its discharging opening after the mixing through expecting that pipe 15 is injected in the static blender 16, has accomplished the process of whole metering in proportion, batch mixing and output.
Claims (2)
1. rotary all-electric pair of component measuring pump of leading screw; Comprise driving mechanism; The pump housing (3); Material pipe (15) and static blender (16); The charging aperture of pump housing lower end contacts with A component (1) or B component (2) in the charging basket through pressing plate (17); Pump housing axle (4) links to each other with ball-screw nut (7) through adapter sleeve (5); Ballscrew shaft (8) top links to each other with accurate planetary reduction box (11) through bearing block (9); Servomotor (12) projecting shaft connects accurate planetary reduction box (11); The upper cross plate of fixed bearing block (10); Fixedly the lower cross plate of the pump housing (14) is parallel to each other with slide plate (6) placed in the middle, and three's left and right sides respectively has the guide pillar (13) of common double as connecting rod.
