The utility model belongs to the technical field of pharmaceutical equipment, and relates to an online powder gravimetric  batch blender.

Background technique:
In powder production, each material is blended on-line. Different powder materials need to be weighed separately. The weighed materials enter the packaging container on the conveyor line, and then they are sealed. Different materials require separate ingredients and gravimetric mechanisms. , The existing batching gravimetric mechanism has a complicated structure and incomplete feeding, which causes the gravimetric value to be inconsistent with the actual feeding value.
Technical realization elements:
The purpose of the utility model is to provide an online powder gravimetric and batching mixer in view of the above-mentioned problems in the existing technology. The technical problem to be solved by the utility model is how to improve the precision of the batching.
powder gravimetric batch blender,gravimetric batch blender
The purpose of the utility model can be achieved by the following technical solutions: an online powder gravimetric and batching mixer, characterized in that the batching mixer includes a number of gravimetric and unloading mechanisms, the gravimetric and unloading mechanism includes a mounting frame, A support rod, a balance rod and a hopper, the hopper is fixed at one end of the balance rod, the other end of the balance rod has a pulley, the middle of the balance rod is hinged with the support rod, and the support rod is fixed on the mounting frame, The lower end of the hopper is open, the balance bar has a guide hole in it, a slide bar is slidably connected to the guide hole, and one end of the slide bar has a shutter that can cover the opening at the lower end of the hopper. The sliding rod and the balance rod are connected by a return spring in a compressed state, the other end of the sliding rod is connected with a pull rope, and the pull rope is fixedly connected to the mounting frame after passing through the pulley; the mounting frame is fixed An armature column is provided, an energizing coil is wound on the armature column, and an iron block corresponding to the armature column is fixedly arranged on the balance rod.
The conveyor belt is located under the hopper, and the mounting frame is fixed on the frame on the side of the conveyor belt. A number of gravimetric and unloading mechanisms are sequentially arranged on the side of the conveyor belt. The packaging container passes intermittently on the conveyor belt. The discharging tank on the frame, the powder material enters the hopper at a constant speed and a small flow rate, and is subjected to the magnetic adsorption of the iron block by the armature column. After the material in the hopper reaches the set value, the armature column separates from the adsorption force on the iron block, and the balance bar Tilt to the side of the hopper, and at the same time, stretch and pull to drive the slide bar to move, the shutter is pulled away from the lower end of the hopper, and the bottom of the material is opened when the hopper is inclined, and the material falls into the corresponding packaging container. A contact switch is set between the iron block and used to control the opening and closing of the lowering tank, so that the hopper is in the feeding state and the lowering tank is closed, so that every gravimetric is accurate.
Because the hopper is in an inclined state during the cutting process, the cutting is complete, and the return spring can drive the slide bar to move to the side of the hopper, thereby pulling the balance bar back to position. After returning to a certain degree, the armature column and the iron block can interact with each other. Adsorption.
composition:
1. Mounting frame; 2. Support rod; 3. Balance rod; 4. Hopper; 51, pulley; 52, slide bar; 53, shutter; 54, return spring; 55, pull rope; 61, armature column; 62, Iron block.
Detailed ways
The following are specific embodiments of the present utility model combined with the accompanying drawings to further describe the technical solution of the present utility model, but the present utility model is not limited to these embodiments.
The batching mixer includes several gravimetric and unloading mechanisms. The gravimetric and unloading mechanism includes a mounting frame 1, a support rod 2, a balance rod 3, and a hopper 4. The hopper 4 is fixed at one end of the balance rod 3, and the other end of the balance rod 3 has A pulley 51, the middle of the balance bar 3 is hinged with the support rod 2, the support rod 2 is fixed on the mounting frame 1, the lower end of the hopper 4 is open, the balance rod 3 has a guide hole in it, and the slide rod 52 is slidably connected in the guide hole, One end of the slide bar 52 has a shutter 53 that can cover the opening at the lower end of the hopper 4. The slide bar 52 and the balance bar 3 are connected by a return spring 54 in a compressed state, and the other end of the slide bar 52 is connected with a pull rope. 55. The draw rope 55 is fixedly connected to the mounting frame 1 after passing through the pulley 51; the mounting frame 1 is fixedly provided with an armature column 61, the armature column 61 is wound with an energizing coil, and the balance rod 3 is fixedly provided with a piece and the armature column 61 The corresponding iron block 62.
The conveyor belt is located under the hopper 4, the mounting frame 1 is fixed on the frame on the side of the conveyor belt, multiple gravimetric and unloading mechanisms are sequentially arranged on the side of the conveyor belt, the packaging containers pass intermittently on the conveyor belt, and the hopper 4 is set above There is a discharging tank fixed on the frame, the powder material enters the hopper 4 at a uniform speed and a small flow rate, and is subjected to the magnetic adsorption of the armature column 61 to the iron block 62. After the material in the hopper 4 reaches the set value, the armature column 61 separates from the With the adsorption force of the iron block 62, the balance bar 3 is inclined to the side of the hopper 4. At the same time, the slide bar 52 is moved by the stretching and pulling, and the shutter 53 is withdrawn from the lower end opening of the hopper 4, and the material is in the inclined state of the hopper 4 The bottom is opened, and the material falls into the corresponding packaging container. A contact switch is set between the armature column 61 and the iron block 62 to control the opening and closing of the feeding tank, so that the hopper 4 is in the feeding state. It is turned off to make every gravimetric accurate.
Since the hopper 4 is in an inclined state during the feeding process, the feeding is complete, and the return spring 54 can drive the slide bar 52 to move to the side of the hopper 4, thereby pulling the balance bar 3 back to position. After returning to a certain degree, the armature column 61 and The iron blocks 62 can adsorb each other.
