Abstract

The utility model discloses a pressure overload protection device comprising an upper pressuring wheel shaft swiveling jib (1), an upper pressuring wheel shaft (2), a joint (3), an extension rod (4) and an oil pressure cylinder (5). The pressure overload protection device is characterized in that the upper pressuring wheel shaft swiveling jib (1) is sleeved on the upper pressuring wheel shaft (2), the joint (3) is arranged at the right end of the upper pressuring wheel shaft swiveling jib (1), the oil pressure cylinder (5) is arranged on a lever, and the joint (3) is connected with the oil pressure cylinder (5) through the extension rod (4). When the pressure is overloaded, the oil outlet at the upper end of the oil pressure cylinder (5) leaks oil, and a cylinder rod of the oil pressure cylinder (5) moves upward to drive the upper pressuring wheel shaft swiveling jib (1) to swing causing the upper pressuring wheel shaft (2) to rotate anticlockwise to drive an upper pressuring wheel to shift upward leading the distance between the upper pressuring wheel and a lower pressuring wheel to be larger and the pressure to be reduced and accordingly achieving the purpose of pressure overload protection. The utility model avoids the blockage and component damage, improves the production efficiency and prolongs the service life.

Description

A kind of pressure overload protection device
One, technical field
The utility model relates to a kind of pharmaceutical machine, particularly relates 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, utility model content
The purpose of this utility model provides 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 utility model 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 the utility model pressure overload protection device.
Among the figure: 1. upper pressure wheel axle pivoted arm 2. upper pressure wheel axles 3. joints 4. extension bars 5. oil pressure cylinders
Five, the specific embodiment
Pressure overload protection device of the present utility model is described further by following drawings and Examples.
As shown in Figure 1: pressure overload protection device of the present utility model 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.
