Abstract
An air flow balance structure of a tablet press is characterized in that materials mixed with air are sucked into a closed cavity through a suction port under the action of a vacuum generator, the materials can fall into a discharging pipeline from the closed cavity after the suction is stopped, and then fall into a feeder from the discharging pipeline, meanwhile, an internal circulation can be formed in the closed cavity, the discharging pipeline, the feeder and an exhaust hose by air formed by the air sucked into the closed cavity, so that air pressure generated by the air flowing into the closed cavity is stable, the air flow is prevented from being formed into a turbulent flow and being sprayed out from a valve actuator, a sealing ring connected with the discharging pipeline and the feeder, and the like, dust is effectively prevented from entering the air to pollute the working environment, and the stable quality of subsequently produced products is ensured.
Description
Technical Field
The utility model relates to an air current balanced structure of tablet press.
Background
The tablet press is an automatic continuous production device for pressing granular materials into tablets, and is mainly applied to pharmacy. During the working process of the tablet press, a vacuum feeding machine in the tablet press sucks materials doped with air, in the process of sucking the materials, gas turbulence can be formed in a pipeline of the vacuum feeding machine and a sealed cavity for containing the materials, after the sucking is stopped, a valve actuator on the side wall of the sealed cavity for containing the materials is opened, the materials pour downwards and fall into a material feeder along discharging pipelines on two sides of the bottom of the sealed cavity for containing the materials, meanwhile, the disordered air flow in the tablet press needs to find a pressure relief opening, the disordered air flow can be ejected out from the valve actuator and a sealing ring connected with the discharging pipeline and the material feeder, and the interior dust can be brought out together during the ejection, so that the production environment is severe, and the quality of subsequently produced products is unstable.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can make the balanced structure of air current in the vacuum material loading machine of tablet press, avoid the dust blowout in the vacuum material loading machine to the air in and pollute operational environment, guarantee the product quality stability of follow-up production.
An air current balanced structure of tablet press, including the airtight cavity of dress material, lower part in airtight cavity is provided with the three-way valve, two interfaces of three-way valve are equallyd divide and do not correspond sealing connection with two exhaust hose that run through airtight cavity, set up the backward flow gas vent on last glassware, the tip of every exhaust hose all with the last backflow gas vent sealing connection on the glassware that corresponds the side.
An air current balanced structure of tablet press, effect through vacuum generator, make the material that is mingled with the air inhale airtight cavity inside by inhaling the material mouth, after stopping inhaling the material, the material can be by during airtight cavity falls the unloading pipeline, descend to the glassware in by the unloading pipeline again, and simultaneously, the air current that is inhaled air formation in the airtight cavity can be at airtight cavity, the unloading pipeline, form an inner loop in last glassware and the exhaust hose, thereby the atmospheric pressure that the air current that makes among the airtight cavity produces is steady, avoid the air current to form the sinuous flow and from local blowout such as sealing washer department that valve executor and unloading pipeline and last glassware are connected, effectively avoid in the dust gets into the air and pollute operational environment, also guarantee follow-up production's product quality stable.

Detailed Description
The utility model provides an air current balanced structure of tablet press, as shown in figure 1, including the airtight cavity 1 of dress material, lower part in airtight cavity 1 is provided with three-way valve 2, two interfaces of three-way valve 2 are equallyd divide and are corresponded sealing connection with two exhaust hose 3 that run through airtight cavity 1 respectively, set up the backward flow gas vent on last glassware 4, every exhaust hose 3's tip all with the backward flow gas vent sealing connection on the last glassware 4 that corresponds the side. Through the action of the vacuum generator 5, the material mixed with air is sucked into the closed cavity 1 through the suction port 6, after the suction is stopped, the material can fall into the discharging pipeline 7 from the closed cavity 1 and then fall into the charging device 4 through the discharging pipeline 7, meanwhile, an internal circulation can be formed in the closed cavity 1, the discharging pipeline 7, the charging device 4 and the exhaust hose 3 by airflow formed by the air sucked into the closed cavity 1, so that the air pressure generated by the airflow entering the closed cavity 1 is stable, the airflow is prevented from being formed into a turbulent flow and being sprayed out from the valve actuator 8, a sealing ring connected with the discharging pipeline 7 and the charging device 4 and the like, the dust is effectively prevented from entering the air to pollute the working environment, and the quality stability of a subsequently produced product is also ensured.
The two exhaust hoses 3 are symmetrically arranged on two sides of the three-way valve 2, so that the air flow circulation is more stable and smooth.
A three-way support 9 is arranged in the closed cavity 1, the three-way valve 2 is arranged in the three-way support 9, and the two exhaust hoses 3 are respectively connected with the interfaces of the three-way support 9 on the corresponding side in a sealing manner. The two exhaust hoses 3 can be symmetrically arranged on two sides of the three-way support 9, so that stable and smooth circulation of air flow is ensured.
The short side of the three-way support 9 is perpendicular to the upper end face and the lower end face of the closed cavity 1, and the long side of the three-way support 9 is perpendicular to the side wall face of the closed cavity 1, so that air flows in the exhaust hoses 3 at two ends of the three-way support 9 can be kept balanced.
The side wall of the closed cavity 1 is provided with the valve actuator 8, the three-way support 9 is arranged below the valve actuator 8, so that air flow formed by air can enter internal circulation, excessive air flow is prevented from being sprayed out from the valve actuator 8 and a sealing ring connected with the feeding device 4 and the like due to the fact that the excessive air flow cannot enter the internal circulation, the quality of products produced in the follow-up process is further guaranteed to be stable, and dust is effectively prevented from entering the air to pollute the working environment.
