Abstract
The invention discloses a raw material weighing and metering device of a polyurethane mixer. The device comprises a storage hopper; the storage hopper is provided with a feeding hole and a discharge hole; the side wall of the storage hopper is connected with one end of a weighing sensor; the other end of the weighing sensor is fixedly arranged on a fixed support; and a speed regulating discharge valve is arranged at the discharge hole of the storage hopper. The device has the advantages that: because the weighing sensor is arranged on the storage hopper, the raw material in the storage hopper can be directly weighed; and the device is simple and accurate, and avoids the phenomena of chromatic aberration, instable quality and the like due to the adding error of the raw material.
Description
Technical field
The present invention relates to the raw material WT-MSR on the polyurethane batch mixer.
Background technology
The polyurethane batch mixer is when foam production; Raw material is delivered into earlier in the storage bin hopper on the polyurethane batch mixer through the spiral feeder; Described storage bin hopper is provided with charging aperture and discharging opening, and its charging aperture is connected with the spiral feeder, and its discharging opening is connected with the batch mixing chamber of polyurethane batch mixer.Present raw material metering method is: through calculating in the spiral feeder frequency control motor in the weight of inside spin feeder transferring raw material of following unit interval of different rotating speed; Thereby configure the rotating speed and the corresponding duration of runs thereof of frequency control motor in the spiral feeder, control the weight of the raw material in the storage bin hopper.Above-mentioned metering method is complicated, and accurate inadequately, and each raw material error of adding is bigger, make the product of at every turn producing have aberration, and quality is unstable.
Summary of the invention
The objective of the invention is: the raw material Weighing device that a kind of metering method is simple, can accurately count heavy polyurethane batch mixer is provided.
For realizing above-mentioned purpose; The technical scheme that the present invention adopts is: the raw material Weighing device of polyurethane batch mixer; Comprise storage bin hopper, described storage bin hopper is provided with charging aperture and discharging opening, and the sidewall of described storage bin hopper is connected with an end of LOAD CELLS; The other end of described LOAD CELLS is fixedly installed on the fixed support, and the discharging opening place of described storage bin hopper is provided with the speed governing blow-off valve.
Further, the raw material Weighing device of aforesaid polyurethane batch mixer wherein, also is provided with pneumatic hammer on the sidewall of described storage bin hopper.
Advantage of the present invention is: on storage bin hopper, be provided with LOAD CELLS; Just can be directly the weight of the inner raw material of storage bin hopper be weighed up; This apparatus structure is simple, metering is accurate, has avoided causing because of the error that raw material adds the generation of phenomenons such as aberration and quality instability.
Description of drawings
Fig. 1 is the structural representation of the raw material Weighing device of polyurethane batch mixer of the present invention.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment the present invention is done further detailed description.
As shown in Figure 1; The raw material Weighing device of polyurethane batch mixer comprises storage bin hopper 1, and described storage bin hopper 1 is provided with charging aperture 12 and discharging opening 11; The sidewall of described storage bin hopper 1 is connected with an end of LOAD CELLS 2; The other end of described LOAD CELLS 2 is fixedly installed on the fixed support 3, and discharging opening 11 places of described storage bin hopper 1 are provided with speed governing blow-off valve 4, on the sidewall of storage bin hopper 1, also are provided with pneumatic hammer 5.
Principle of work of the present invention is following: during use, charging aperture 12 is connected with the spiral feeder, discharging opening 11 is connected with the batch mixing chamber of polyurethane batch mixer; The spiral feeder is delivered into raw material in the storage bin hopper 1 that is connected with the batch mixing chamber of polyurethane batch mixer from charging aperture 12, when the weight of storage bin hopper 1 reached setting value, LOAD CELLS 1 sent in the electronic controller of signal to polyurethane batch mixer; Electronic controller transmits signal and gives pneumatic hammer 5; Make its sidewall that begins to impact storage bin hopper 1, and send signal speed governing blow-off valve 4 is opened, raw material just is delivered in the batch mixing chamber of polyurethane batch mixer from discharging opening 11 like this; The raw material that makes in the storage bin hopper 1 that impacts of pneumatic hammer 5 becomes flexible; Discharge from discharging opening 11 more easily, and make raw material be difficult to be bonded on the inwall of storage bin hopper 1, improved the precision of metering better.
Advantage of the present invention is: on storage bin hopper 1, be provided with LOAD CELLS 2, just can directly enough weight with storage bin hopper 1 inner raw material weigh up, this device is simple, accurate, has avoided causing because of the error that raw material adds the generation of phenomenons such as aberration and quality instability.
Claims (2)
