Abstract
The utility model discloses a nut-rotating type all-electric liquid rubber injecting unit, comprising a material cylinder (9), a piston (8), a feeding pipe (10) and a discharging pipe (11), wherein a piston rod (7) of the piston is connected with a ball screw shaft (5) by a sliding plate (6); a ball screw nut (2) is connected with a belt transmission device (15), a bearing seat (16) and the ball screw shaft (5); the belt transmission device (15) is also connected with a precise planetary speed reducing box (3) which is connected with an extending shaft of a servo motor (1); an upper cross plate (13) for fixing the material cylinder (9), a lower cross plate (4) for fixing the bearing seat (16) are mutually parallel to the sliding plate (6) between the upper cross plate (13) and the lower cross plate (4); the left sides and the right sides of the upper cross plate (13), the lower cross plate (4) and the sliding plate (6) are respectively provided with guiding columns (14) which are also used as connecting rods; and the feeding pipe (10) and the discharging pipe (11) are provided with stop valves (12). Compared with the existing hydraulic driving similar machine, the nut-rotating type all-electric liquid rubber injecting unit has the advantages that the accuracy is high, the material injecting amount is accurate, the deviation is less, the displacement and the speed of the piston are controllable, the material is saved, the energy is saved and no noise is caused and the like.
Description
Technical field
The utility model relates to the injection machinery in a kind of liquid rubber make-up machine, is to be liquid rubber injection duplex machine, three-line machine or a how online unit of power with the motor.
Background technology
The injector of liquid rubber is online form when reality is used, according to what of liquid rubber manufactured goods raw material components, it is online to cooperate injecting unit with respective numbers to carry out, the usefulness duplex machine of two components, three components use three-line machine, the rest may be inferred by analogy.In the industry; Adopt the hydraulic-driven injector of enterprise production such as German 2KM company all the time; 200610149061 " low viscosity rubber extrusion forming vulcanization devices " of having authorized like the applicant; Also belong to this type of machinery, these machineries are bulky, pipeline is many, easy oil leakage, service life are not satisfactory.With such device fabrication liquid rubber goods, can't accurately control the materials amount, precision is low; The materials deviation is big, scraps because of lacking material for preventing goods, needs to strengthen the surplus of injecting material; Thereby the material that has increased in the mould is pressed, and produces thermal expansion along with the material temperature rises, and pressure is higher; Be prone to cause goods crackings and scrap, can only reduce thermal expansion by cooling, but cooling can cause again production efficiency low.It is thus clear that the precision of liquid rubber injector is low can bring a series of problem to production of articles.
The utility model content
The technical problem that the utility model will solve is to design the all-electric liquid rubber injecting unit of a kind of nut rotary type, in order to assemble duplex, three or the injector that joins as required more.
The technical scheme that solves this technical problem employing is: the all-electric liquid rubber injecting unit of this nut rotary type; Comprise material cylinder, piston, feed pipe and discharge nozzle; The piston rod of piston is connected with ballscrew shaft through slide plate; Ball-screw nut is connected with belt drive unit, bearing block and ballscrew shaft, and belt drive unit also is connected with accurate planetary reduction box, and the latter is connected with the servomotor projecting shaft again; The lower cross plate of the upper cross plate of fixing material cylinder and fixed bearing block and accurate row amount reduction box; And the slide plate that connects ballscrew shaft and piston rod between this two transverse slat is parallel to each other, and three's left and right sides respectively has the guide pillar of double as connecting rod, on feed pipe and the discharge nozzle stop valve is arranged.
Said belt drive unit is to be with and the synchronous pulley device synchronously.
The beneficial effect of the utility model is that the shot deviation is little because of the precision of piston displacement is high, and the speed of piston displacement is controlled on any position; Can realize accurate material feeding, produce the high dimensional accuracy goods, non-trimming; Material-saving, this cellular construction is compact, few, the long service life of pipeline.Energy-conservation, noiselessness.
Description of drawings
Accompanying drawing is the all-electric liquid rubber injecting unit of a nut rotary type structural representation.
The specific embodiment
Following the utility model combines embodiment and details with reference to accompanying drawing: with reference to accompanying drawing; The all-electric liquid rubber injecting unit of this nut rotary type; Comprise material cylinder 9, piston 8, feed pipe 10 and discharge nozzle 11, the piston rod 7 of piston is connected with ballscrew shaft 5 through slide plate 6, and ball-screw nut 2 is connected with belt drive unit 15, bearing block 16 and ballscrew shaft 5; Belt drive unit 15 also is connected with accurate planetary reduction box 3; The latter is connected with servomotor 1 projecting shaft again, the upper cross plate 13 of fixing material cylinder 9 and the lower cross plate 4 of fixed bearing block 16 with accurate row amount reduction box 3, and this two transverse slat 13, connect ballscrew shaft 5 and piston rod 7 between 4 slide plate 6 parallel to each other; Three's left and right sides respectively has the guide pillar 14 of double as connecting rod, on feed pipe 10 and the discharge nozzle 11 stop valve 12 is arranged.
Said belt drive unit 15 is to be with and the synchronous pulley device synchronously.
During use, start servomotor 1, the setting value that parameters such as its rotating speed are pressed in the microcomputer is carried out; Servomotor slows down through accurate planetary reduction box 3, drives ball-screw nut 2 rotations by belt drive unit 15, and ballscrew shaft 5 is changeed clockwise; Piston moves back for 8 times, and material enters material cylinder 9 to set amount by feed pipe 10, and after this servomotor 1 just changes counterclockwise; Piston 8 rises, and will expect to inject mould or static blender through discharge nozzle 11 in full.
The duplex machine is that both discharge nozzles lead in same mould or the static blender by the associating of two this full electric type liquid rubber injecting units, three-line machine, how online all like this mode carry out the associating of three unit, a plurality of unit, carefully do not state.
