Abstract
The invention discloses a buffer disc dustband ejector of a high-speed rotary tablet machine, mainly comprising a screw bolt, a jacket, a first half core, a second half core and a nut, wherein the jacket coats the main body parts of the first half core and the second half core and is fixed together with the first half core through a screw; the first half core and the second half core are respectively provided with a tine protruding out of the jacket; the jacket and the side walls of the first half core and the second half core are respectively provided with through holes, and the screw bolt is in threaded connection with a screw cap after passing through the through holes.
Description
Technical field
The present invention relates to a kind of provision for disengagement of tablet press machine punch plate dust ring, especially a kind of buffer disc dustband ejector of high-speed rotary tablet machine belongs to the pharmaceutical equipment field.
Background technology
Highspeedrotarytabletpress is the medicine tablet manufacturing equipment of using always, by selecting the tool that dashes of different size for use, can suppress the tablet of disk, special-shaped tablets, impressing pattern and literal.Tablet press machine generally is made up of frame-type supporting construction, machine driven system, compressing tablet chamber, hydraulic system, lubricating system, filling device, slice device, electric control operation system.Wherein compressing tablet is indoor mainly by the punch plate assembly, form towards parts such as tool, main pinch rollers, and the punch plate assembly comprises upper and lower punch plate again.During tablet press machine work, under main pinch roller effect, in upper and lower punch plate, move back and forth, make towards the last low punch of tool and exert pressure, finish the compressing tablet process to medicinal powder towards tool.
When last low punch moves reciprocatingly in upper and lower punch plate, medicinal powder can be brought in the punching of punch plate, influence the normal operation of drift.For preventing that drift from bringing medicinal powder into punching, in upper and lower disk punching, hole punching, dust ring is installed usually.Owing to move back and forth at a high speed in punch plate towards tool during work, therefore dust ring needs to change dust ring in use for some time often because of causing damage with upper and lower drift high-speed friction.And dust ring and punch plate are blurted out and are closely linked, and also are not specifically designed to the device of loading and unloading dust ring in the prior art, can only use sharp-pointed aid, adopt mode such as prize, strike to load and unload dust ring.This handling mode not only difficulty is big, and very easily damages disk punching, hole punching.
Summary of the invention
The problem that the objective of the invention is to easy damaged disk punching, hole punching in, the cargo handling process big at tablet press machine punch plate dust ring loading and unloading difficulty provides a kind of dust ring handling instrument of special use, i.e. the dust ring ejector.
Dust ring ejector of the present invention mainly comprises bolt, overcoat, the first half cores, the second half core and nuts, and wherein overcoat has wrapped up the main part of the first half cores and the second half cores, and overcoat is fixed together with the first half cores by screw; The first half cores and the second half cores have tip to protrude in outside the overcoat respectively; Be respectively equipped with through hole on the sidewall of overcoat and the first half cores, the second half cores, bolt passes described through hole and nut is spirally connected.
Dust ring ejector provided by the invention can be in place dust ring exactly, avoids in installation process the punch plate mouth being damaged, and can save time, and efficient can improve more than 2 times; Can very easily dust ring be dismantled with the dust ring ejector, avoid equally in unloading process the punch plate mouth being damaged, and can save time, efficient can improve more than 3 times.
Description of drawings
Fig. 1 is the structural representation of dust ring ejector
Accompanying drawing 2 be among Fig. 1 the dust ring ejector along A-A to cutaway view
The specific embodiment
Referring to accompanying drawing, dust ring ejector of the present invention mainly comprises bolt 1, overcoat 2, the first half cores 3, the second half core 4 and nuts 5, wherein overcoat 2 has wrapped up the main part of the first half cores 3 and the second half cores 4, and overcoat 2 is fixed together with the first half cores 3 by screw 6; The first half cores 3 and the second half cores 4 have tip 31 and 41 to protrude in outside the overcoat 2 respectively; Be respectively equipped with through hole on the sidewall of overcoat 2 and the first half cores 3, the second half cores 4, bolt 1 passes described through hole and nut 5 is spirally connected.
When adopting ejector of the present invention to dismantle dust ring, to a direction rotating screw cap 5, can drive the first half cores 3 and the second half cores 4 are close mutually,, ejector be put into the dust ring endoporus of upper punch plate and lower punch plate respectively near when tip 31 and 41 can be put into the endoporus of dust ring; Rotating screw cap 5 round about again, drive the first half cores 3 and the second half cores 4 outwards launch, make tip 31 and 41 and the dust ring inwall be adjacent to, stretching dust ring from inside to outside, this moment is the application of force in the punching of upper punch plate and lower punch plate respectively, masterpiece is used on the inner bottom surface of overcoat 2, makes ejector break away from punch plate together with dust ring and blurts out.
When dust ring is installed, just opposite with disassembly sequence, make ejector stretching dust ring earlier, dust ring is placed the disk punching, hole punching place, the application of force in the punching of upper punch plate and lower punch plate respectively then, masterpiece is used on the outer bottom of overcoat, dust ring is compressed into disk punching, hole punching, dust ring is installed.
Half core can accurately be fixed on the appropriate location when making molding, can a sleeve 7 be set between nut 5 and overcoat 2, sleeve 7 is provided with the alignment pin 8 that pierces sleeve wall, and bolt 1 passes sleeve 7 and is spirally connected with nut 5, when nut turns to correct position, can bolt be located by this alignment pin 8.
For further fixing the position of half core, also pad 9 can be installed between sleeve 7 and overcoat 2.
In the above-mentioned installation and removal process,, therefore can not damage punching, and cargo handling process is simple and efficient because ejector does not directly contact with punching.
