Abstract
The utility model relates to a sealing device between a feeder supporting plate and a rotary table, which comprises the feeder supporting plate and a sealing strip. The position of the feeder supporting plate close to the rotary table is provided with a circular-arc step, a circular-arc groove with the U-shaped cross section is arranged along the step of the feeder supporting plate, the length of the circular-arc groove is equal to that of the step, one side of the sealing strip extends to form an insert edge so that the cross section of the sealing strip is right-angled, and the insert edge of the sealing strip is placed in the U-shaped arc circular-arc groove of the step of the feeder supporting plate. The feeder supporting plate is combined with the sealing strip so that circular arcs are coupled tightly to form smooth circular-arc surfaces, the radius of the circular arcs is identical to the outer diameter of the rotary table, and then the circular arcs can tightly cling to the outer circle of the rotary table, thereby preventing fine powder in materials from leaking outwards and prolonging service life of the sealing strip. As a plurality of mounting screw holes and screws are omitted, the sealing strip has fine interchangeability and is conveniently and fast in assembly and replacement.
Description
[technical field]
The utility model relates to rotary tablet machine feeder supporting plate that industry production such as pharmacy, food use and the sealing device between turntable.
[background technology]
During rotary tablet machine work, the sealing strip of making of nonmetallic materials between the feeder supporting plate that maintains static and the turntable of rotation separates.Present sealing strip is fastened on the feeder supporting plate arch steps by a plurality of sunk screws, and another side is close to the turntable cylindrical, thereby prevents that fine powder spills in the material, plays sealing function.
There is following shortcoming technically in above-mentioned sealing device: one, sealing strip is fixed on the feeder supporting plate arc-shaped surface by a plurality of sunk screws, the joint portion is that the arc-shaped surface by the side plane of sealing strip and supporting plate step constitutes, similar in appearance to the circumference inscribed polygon, cannot not contact slidingly suitablely with the arc surface of turntable cylindrical thereby have influence on sealing strip, influence sealing strip service life; They are two years old, sealing strip is a consumable accessory, if the spare part that factory provides is made installing hole in advance, can cause installation screw misalignment with feeder supporting plate arc surface, if the raising machining accuracy guarantees the interchangeability of sealing strip then will significantly increase cost, As-Is is that the sealing strip spare part that factory offers the user does not have installing hole, joins work voluntarily by the user, brings inconvenience to the user.
[summary of the invention]
The utility model improves at the problems referred to above, and providing a kind of can fit tightly with feeder supporting plate arc surface, and it is suitable to contact cunning again with the arc surface of turntable, can also make to change the quick and easy sealing device of spare part.
The technical solution of the utility model is: the sealing device between a kind of feeder supporting plate and turntable, comprise feeder supporting plate and sealing strip, feeder supporting plate and turntable are the step of circular arc near the place, it is characterized in that along the step of feeder supporting plate offer a sliver transvers section be the U type, with the isometric arc-shaped slot of step, one side of sealing strip is extended a built-in edges is rectangular in shape the cross section of sealing strip, and the built-in edges of sealing strip places the U type arc groove of feeder supporting plate step.
For making sealing strip not be subjected to the influence of turntable rotation to produce displacement, can adopt further measure: one, the book office of the built-in edges of sealing strip is provided with a waist hole, be provided with the combination bore that through hole and screw are formed at U type arc groove and waist hole correspondence position, described through hole is opened in contiguous turntable one side of U type arc groove, and described screw is opened at U type arc groove away from turntable one side, and a screw passes through hole, one end is tightened in the screw, and the other end is stuck in the sealing strip waist hole; Its two, the built-in edges of sealing strip and U type arc groove interference fit.
Feeder supporting plate of the present utility model combines with sealing strip, the wedging close-fitting of circular arc and circular arc, and the arc surface of formation is sliding suitable, arc radius is consistent with the turntable outside dimension, can fit closely with the turntable cylindrical, prevent that fine powder spills in the material, prolong sealing strip service life.Because of casting out many screw and screw are installed, sealing strip interchangeability is good, assembles, changes convenient and swift.
[description of drawings]
Fig. 1 is the utility model user mode schematic diagram;
Fig. 2 is the utility model perspective view;
Fig. 3 is the A-A cutaway view among Fig. 1.
[specific embodiment]
Be described further below in conjunction with the utility model embodiment and accompanying drawing thereof.
As the sealing device between each a kind of feeder supporting plate shown in the drawings and turntable, comprise feeder supporting plate 1 and sealing strip 2, feeder supporting plate 1 is the step 11 of circular arc with turntable 4 near the place, present embodiment along the step 11 of feeder supporting plate offer a sliver transvers section be the U type, with the isometric arc-shaped slot 12 of step, one side of sealing strip 2 is extended a built-in edges 21 is rectangular in shape the cross section of sealing strip 2, and the built-in edges 21 of sealing strip 2 places the U type arc groove 12 of feeder supporting plate step 11.The sealing strip 2 of present embodiment can guarantee that with the assembling mode of the U type arc groove 12 of feeder supporting plate step 11 joint portion also is to be arc surface, consistent with the external arc of turntable 4, can be adjacent on the external arc of turntable 4, both improve sealing property, reduce friction between the two again.
For making sealing strip not be subjected to the influence of turntable rotation to produce displacement, the built-in edges 21 of sealing strip adopts interference fit with U type arc groove 12.The book office of the built-in edges 21 of sealing strip 2 is provided with a waist hole 22 again, be provided with the combination bore of through hole 13 and screw 14 compositions at U type arc groove 12 and waist hole 22 correspondence positions, through hole 13 is opened in U type arc groove 12 contiguous turntable 4 one sides, screw 14 is opened at U type arc groove 12 away from turntable 4 one sides, one screw 3 passes through hole 13, one end is tightened on 14 li of screws, the other end is stuck in 22 li in sealing strip waist hole, so generally speaking strengthening measure only needs one group of combination bore and waist hole 22, has avoided changing the problem of spare part misalignment screw fully.
When changing sealing strip, screw out screw 3, trip out sealing strip 2, new sealing strip 2 is loaded onto, screw screw 3 and get final product.
