Application of Gravimetric dosing system


The plastic metering uniform mixing equipment adds the main and auxiliary materials to the equipment in a certain proportion, and the equipment evenly mixes and stirs the required proportion of materials, and the weighing and mixing values are more accurate. In the prior art plastic mixing, the main material and auxiliary materials are manually weighed in a certain proportion, then poured into the mixer and stirred, and finally transferred to the heating cylinder of the injection molding machine. Therefore, the main material must be added to. Weighing in proportion to auxiliary materials is inefficient, and the operation is very troublesome, and continuous mass production is impossible. The new weighing and mixing equipment will solve many problems. Automatic feeding, automatic weighing, automatic mixing and automatic unloading. Due to the software digital program system, the weighing error is very accurate, and the particles can be accurate to the particles. Make the blend value more accurate.

The specific embodiment of the new weighing mixer is only and is not used to limit the present utility model. For those skilled in the art, the new weighing mixer can have various changes and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the new weighing mixer should be included in the protection scope of the present invention.

It can mix 1 kind of pellet, 2 kinds of granules, 3 kinds of color masterbatches granules, 4 kinds of resin particles, 5 kinds of plastic pellets, 6 kinds of powders, 7 kinds of color masterbatches, and more plastic granules. For example: POM, ABS, TPE, PAL, ABS, CAB, EVA (2), EVOH, LM (4), LCP, PA11, PA6.46.6, PAI, PAR, PBT, PC,PC/ABS,PC/PBT,PE.HDEPE,LDPE black3%,PE.HDEPE.LDPE black40%,PEEK,PE(1), PEN,PES,PET,PETG,PI,PMMA,POM,PP,PPO,PPS,PS,[GPPS.EPS.HIPS],PSU,PIT,PUR, PVC, SAN, SB, TPE, TPE, TPO, TPU, and other plastic granular resin materials or powder color masterbatches

Operation Guide for Gravimetric dosing system

The auxiliary material conveying and weighing mechanism of the plastic mixing automatic feeding system is characterized by including more than two auxiliary material feeding bins, a spare feeding bin and a central dust collector. Each auxiliary material feeding bin and the spare feeding bin are passed through a dust suction pipe The central dust collector is connected, and the dust suction pipe is equipped with a pneumatic butterfly valve. The auxiliary material feeding bin includes a feeding port in the bin body and a bin door. A proximity switch is set on one side of the feeding port to contact the bin door. The proximity switch is connected to the pneumatic butterfly valve and the switch of the central dust collector.
There is a screw conveying device under the silo body, the outlet of the screw conveying device is connected to the first discharging pipe with a pneumatic flapper valve, the first discharging pipe is connected to the auxiliary material sub-metering tank, the first lower of two or three auxiliary material feeding bins The material pipe is connected to an auxiliary material sub-metering tank. The auxiliary material sub-metering tank is equipped with an auxiliary material electronic scale. The auxiliary material sub-metering tank is connected to the second discharge pipe and is equipped with a pneumatic clamping valve. The second discharge pipe is connected to the auxiliary material total measuring tank. The total auxiliary material measuring tank is equipped with a total auxiliary material electronic scale, and the discharge pipe is connected under the auxiliary material total measuring tank.
The auxiliary material conveying and weighing mechanism of the new plastic mixing automatic feeding system. At work, when workers want to open the warehouse door to put in auxiliary materials, the warehouse door does not touch the proximity switch, and the proximity switch controls the pneumatic butterfly valve and the central dust collector (the specific structure of the dust collector).
The central dust collector (based on the existing technology) is opened, and the central dust collector evacuates the inside of each auxiliary material feeding box through the dust suction pipe. When the worker pours each auxiliary material into each auxiliary material feed chute (an auxiliary material), pour it into the auxiliary material feed chute. The corresponding auxiliary material bin can be set according to the number of auxiliary materials. The central dust collector will absorb dust to ensure the sanitation of the working environment. After the auxiliary materials enter the auxiliary material feeding bin, they will drop. The screw conveying device is conveyed to the position of the first discharge pipe by the screw conveying device while stirring. When using auxiliary materials, the pneumatic cartridge valve is controlled by the loop to make the auxiliary materials fall into the second discharge pipe. The auxiliary material auxiliary measuring tank is equipped with auxiliary material auxiliary measuring tank. The auxiliary material electronic scale auxiliary material sub-metering box is connected to two or three auxiliary material feeding boxes at the same time.
The auxiliary material electronic scale weighs 2-3 kinds of auxiliary materials, and mixes 2-3 kinds of auxiliary materials. First, mix them in the auxiliary material auxiliary measuring tank, and then The mixed auxiliary materials mixed in the auxiliary material auxiliary measuring tank are transported to the auxiliary material total measuring tank through the second discharge pipe, and the total amount of auxiliary materials is set as the auxiliary material total measuring tank. The auxiliary material electronic scale is used for the total weighing of the auxiliary material electronic scale and mixing all auxiliary materials, and finally output downward from the discharge pipe.
The auxiliary material conveying and weighing mechanism of the plastic mixing automatic feeding system of this scheme. Workers only need to pour the entire package of auxiliary materials into the auxiliary material feeding box, the auxiliary materials will be automatically transported, and the electronic scale will be proportionally controlled by the circuit. Weighing and mixing do not require workers to weigh separately and then feed materials, thereby improving production efficiency and contributing to automatic continuous production.
