Abstract
The invention discloses a kind of pressure overload protection device; it comprises upper pressure wheel axle pivoted arm (1), upper pressure wheel axle (2), joint (3), extension bar (4), oil pressure cylinder (5); it is characterized in that; upper pressure wheel axle pivoted arm (1) is sleeved on the upper pressure wheel axle (2); joint (3) is installed in the right-hand member of upper pressure wheel axle pivoted arm (1); oil pressure cylinder (5) is installed on the lever, and joint (3) and oil pressure cylinder (5) connect by extension bar (4).When compression force is transshipped; oil pressure cylinder (5) upper end oil-out leaks; the piston rod of oil cylinder moves upward; drive upper pressure wheel axle pivoted arm (1) swing; making upper pressure wheel axle (2) be rotated counterclockwise the drive upper pressure wheel moves up; last lower pressure wheel spacing is from increase, and compression force reduces, and reaches the purpose of compression force overload protection.Avoid phenomenons such as vexed car and part of damage, improved production efficiency, prolonged the service life of machine.
Description
One, technical field
The present invention relates to a kind of pharmaceutical machine, particularly relate in the pharmaceutical machine compression force overload protection arrangement on the rotary tablet machine.
Two, background technology
Usually will have the pressed powder of certain effect or granule materials in industries such as the medicine of China, chemical industry, food is pressed into tablets and becomes tablet or health products.People are called tablet press machine with this plant equipment usually.And punch die is called rotary tablet machine by rotating disk driven rotary and the tablet press machine that pushes up and down with last lower railway.In the tablet press process, upper punch nail moves downward with the descending rail of upper punch, dash down nail with under rush to capable rail and move upward, extruding by last lower pressure wheel then, a powder or a material material are pressed into tablet, and in extrusion process, the power that last lower pressure wheel bears is called compression force.Compression force is along with the thick size of sheet, the variation of the characteristic of what and material of charging quantity and changing.Tablet press machine does not in the market all have pressure overload protection device; after in case puck position is adjusted up and down; last lower pressure wheel relative position just remains unchanged; thick the reducing of sheet when tablet; charging quantity increases or when suppressing the material of easy-formation not; when compression force enlarges markedly, become and just cause tablet press machine vexed car phenomenon to take place, or wheel pressing shaft damages up and down because of pressure overload (surpassing the rated designs value).Not only reduced production efficiency, shorten the service life of machine greatly, and production cost obviously improves.
Three, summary of the invention
The purpose of this invention is to provide a kind of novel pressure overload protection device, to solve the problem that the vexed car phenomenon that causes because of pressure is excessive in the compressing tablet process or parts damage.
To achieve these goals; a kind of pressure overload protection device of the present invention is on the upper pressure wheel axle; increase linkage; when compression force is excessive, by linkage the upper pressure wheel axle is rotated, make on the upper pressure wheel position and move; go up the lower pressure wheel spacing like this from increase; when dashing nail by last lower pressure wheel, extruding force reduces, and has avoided the generation of vexed car phenomenon and the damage of other parts.
The technical scheme of this pressure overload protection device is: it is made up of parts such as upper pressure wheel axle pivoted arm, upper pressure wheel axle, joint, extension bar, oil pressure cylinders.Wherein upper pressure wheel axle pivoted arm is sleeved on the upper pressure wheel axle, and joint is installed in the right-hand member of upper pressure wheel axle pivoted arm, and oil pressure cylinder is installed on the lever, with extension bar joint and oil pressure cylinder is coupled together.
When operation, unclamp the nut on the extension bar, the rotation extension bar drives the swing of upper pressure wheel axle pivoted arm, drives the rotation of upper pressure wheel axle, thereby upper pressure wheel is moved up and down.When upper pressure wheel is regulated the appropriate location, locking nut.When compression force was transshipped, oil pressure cylinder upper end oil-out leaked, and the piston rod of oil cylinder moves upward; drive the swing of upper pressure wheel axle pivoted arm, make the upper pressure wheel axle be rotated counterclockwise the drive upper pressure wheel and move up, last lower pressure wheel spacing is from increase; compression force reduces, and reaches the purpose of compression force overload protection.
The pressure overload protection device of making by technique scheme compared with prior art has following advantage: avoided the vexed car phenomenon that causes because of the pressure overload 1.; 2. avoid the damage of other parts, prolonged machine service life.
Four, description of drawings
Fig. 1: the front view of pressure overload protection device of the present invention.
Among the figure: 1. upper pressure wheel axle pivoted arm 2. upper pressure wheel axles 3. joints
4. extension bar 5. oil pressure cylinders
Five, the specific embodiment
Pressure overload protection device of the present invention is described further by following drawings and Examples.
As shown in Figure 1: pressure overload protection device of the present invention is made up of upper pressure wheel axle pivoted arm (1), upper pressure wheel axle (2), joint (3), extension bar (4), oil pressure cylinder (5); it is characterized in that upper pressure wheel axle pivoted arm (1) is sleeved on the upper pressure wheel axle (2); joint (3) is installed in the right-hand member of upper pressure wheel axle pivoted arm (1); oil pressure cylinder (5) is installed on the lever, with extension bar (4) joint (3) and oil pressure cylinder (5) is coupled together.
When operation, unclamp the nut on the extension bar (4), rotation extension bar (4) drives upper pressure wheel axle pivoted arm (1) swing, drives upper pressure wheel axle (2) rotation, thereby upper pressure wheel is moved up and down.When upper pressure wheel is regulated the appropriate location, locking nut.When compression force is transshipped; oil pressure cylinder (5) upper end oil-out leaks; the piston rod of oil cylinder moves upward; drive upper pressure wheel axle pivoted arm (1) swing; making upper pressure wheel axle (2) be rotated counterclockwise the drive upper pressure wheel moves up; last lower pressure wheel spacing is from increase, and compression force reduces, and reaches the purpose of compression force overload protection.
After adopting technique scheme, when compression force was transshipped, machine can be regulated automatically, has avoided phenomenons such as vexed car and part of damage, has improved production efficiency, has prolonged the service life of machine.
