Abstract
The present invention relates to a flow rate control device of a rotary preforming press of pharmaceutical machinery. The flow rate control device is characterized in that a rotating shaft of a powder apron is installed inside a feeding device, and the powder apron is fixed at the rotating shaft by bolts; a handle of a positioning plate and the positioning plate are welded together and are installed at the rotating shaft, and the handle of the positioning plate and the rotating shaft of the powder apron are linked by pins. Because a flow rate control device is adopted, the powder apron can be just turned, and the size of a material outlet inside the feeding device can be adjusted casually to make the rate of flow of the material inside the feeding material fit for the requirement of preforming and ensure that the material inside the feeding device is correspondingly invariable, and the width error of a troche is convenient for controlling.
Description
One, technical field
The present invention relates to a kind of pharmaceutical machine, particularly relate to a kind of volume control device on the rotary tablet machine of slugging in a kind of pharmaceutical machine.
Two, background technology
In industries such as the medicine of China, chemical industry, food, the solid particle that will have certain effect usually is pressed into tablets and becomes tablet or health products.People also often are called tablet press machine with this class machinery, and in tablet press machine, middle mould are installed on the turntable and with the machinery that turntable rotates be called rotary tablet machine.In rotary tablet machine, generally the parts that a kind of key is all arranged are feeder, and its function is to store material and make material enter middle mould.All do not have material flow amount governor motion in the common in the market feeder, in entering the material of mould how much depend primarily on what of material in the feeder, Flow of Goods and Materials often is in disordered state in the feeder, flow is difficult to control.During use, regular meeting makes the tablet thickness generation difference of compacting, thereby often causes the medicine of compacting defective.Sometimes, if mass flow is too big in the feeder, material is overflowed, this also can cause a large amount of wastes of material.
Three, summary of the invention
The objective of the invention is to provide a kind of volume control device, to solve the tablet press machine problem that mass flow can't be regulated in the feeder in the compressing tablet process, guarantees that the tablet thickness of compacting meets the requirements.
The technical scheme of this volume control device is: increase a rotating powder blocking plate in original feeder exit, by the rotation of powder blocking plate, regulate the mass flow size.This volume control device is made up of parts such as location-plate handle, location-plate, powder blocking plate rotating shaft, powder blocking plates.Wherein, the powder blocking plate rotating shaft is contained in the feeder, and powder blocking plate is screwed in rotating shaft, is sleeved in the rotating shaft after location-plate handle and the location-plate welding, and with pin the location-plate handle is connected with the powder blocking plate rotating shaft.During work, rotate and regulate handle, drive the powder blocking plate rotating shaft and rotate, rotating shaft drives powder blocking plate and rotates together, thereby changes material outlet size in the feeder, reaches the purpose of regulating mass flow.
This volume control device of making according to technique scheme compared with prior art has following advantage: owing to adopted a kind of volume control device, only need to rotate powder blocking plate, just can regulate material outlet size in the feeder arbitrarily, make mass flow adaptation compressing tablet demand in the feeder, be convenient to control the thickness error of tablet.
Four, description of drawings
Fig. 1: a kind of volume control device cutaway view of the present invention.
Fig. 2: the A of a kind of volume control device of the present invention is to view.
Among the figure: 1. location-plate handle 2. location-plates 3. powder blocking plate rotating shafts
4. powder blocking plate 5. trip bolts
Five, the specific embodiment
A kind of volume control device of the present invention is described further by following drawings and Examples.
As shown in Figure 1 and Figure 2: this volume control device is to increase a rotating powder blocking plate (4) in original feeder exit, then, rotates by powder blocking plate, regulates the mass flow size.It is made up of location-plate handle (1), location-plate (2), powder blocking plate rotating shaft (3), powder blocking plate parts such as (4).Wherein, powder blocking plate rotating shaft (3) is contained in the feeder, powder blocking plate (4) is screwed in rotating shaft, location-plate handle (1) is sleeved in the rotating shaft after welding with location-plate (2), and location-plate handle (1) is connected with powder blocking plate rotating shaft (3) with pin, lock-screw (5) is installed on the location-plate handle (1), the angle that the control rotating shaft is rotated.
During work, when rotational positioning plate handle (1), powder blocking plate rotating shaft (3) is rotated thereupon, drives the swing of powder blocking plate (4), thereby changes material outlet size in the feeder, reaches the purpose of regulating mass flow in the feeder.After adjustment finishes, locking lock-screw (5).Like this, it is constant that the mass flow in feeder exit keeps, and to flow in each in the mould inventory identical thereby make, thereby guaranteed the uniformity of tablet thickness.
Adopted the tablet press machine of this volume control device, only needed to rotate powder blocking plate, just can regulate material outlet size in the feeder arbitrarily, thus control enter in mould material what, and make inventory keep constant, also make the thickness of tablet keep even.
Claims (2)
1. volume control device, it is made up of location-plate handle (1), location-plate (2), powder blocking plate rotating shaft (3), powder blocking plate (4), locking lock-screw (5), it is characterized in that: powder blocking plate rotating shaft (3) is contained in the feeder, powder blocking plate (4) is screwed in rotating shaft, location-plate handle (1) is sleeved in the rotating shaft after welding with location-plate (2), and with pin location-plate handle (1) is connected with powder blocking plate rotating shaft (3), lock-screw (5) is installed on the location-plate handle (1).
2. a kind of volume control device according to claim 1 is characterized in that, increases a rotating powder blocking plate (4) in the feeder exit.
