Abstract

The utility model discloses a machine is mixed to proportion of weighing, including storage vat, bucket, weighing sensor and agitator, the storage vat is located the top of agitator, the storage vat bottom is equipped with by motor drive pivoted blowing screw rod, weighing sensor passes through the mounting and sets up in the both sides of agitator upper portion inner wall, the bucket is hung on weighing sensor through the horizontal outwardly directed arm sling that hangs that the upper end both sides were equipped with, it presses in weighing sensor's top to hang the lower surface of arm, the bottom of agitator is equipped with agitating unit. The utility model discloses simplify the structure of equipment, reduced the manufacturing cost of equipment, improved the precision of weighing the plastic raw materials. Simultaneously, the rotatory blowing through the screw rod is weighed to the bucket, can control the blowing speed according to different situation, when showing that weight is close the default, reduces blowing speed and can avoid reaching and still have the more material condition of hopper of weighing that drops yet behind the default, can improve the precision of weighing from this.

Description

Ratio of weighing mixer

Technical field

The utility model relates to plastics injection molding art technology, is specifically related to one and weighs ratio mixer.

Background technology

Often run into by multiple material composition situation used in combination according to a certain percentage on plastic product forming is produced, tradition mixes after manually weighing again, in order to comply with the requirement that industry automation development and Product Precision improve constantly, the plastic pellet having occurred having the heavy function of meter is weighed mixer.

Existing mixer of weighing generally comprises storage vat, to weigh hopper and agitator, weigh hopper by support installing on LOAD CELLS, storage vat is positioned at the top of hopper of weighing, agitator is positioned at the below of charging basket of weighing, storage vat is weighed in charging basket of weighing by the valve opening and closing blowing controlled by cylinder, controller controls the cut out of material inlet valve according to the signal of LOAD CELLS, when weight of weighing is identical with the weight of setting, control to close, directly falling into from the bottom of storage vat due to raw material weighs charging basket, be difficult to ensure the even of charging, therefore still having part material also not drop to completely when just closing weighs in hopper, cause the precision of weighing not high, as the words of the speed of high charging, just there will be larger deviation, the ratio causing raw material to mix is inaccurate, and make to produce the product quality drawn thus and meet the requirements.

Utility model content

The utility model, for the disappearance of prior art existence, provides a kind of structure simple, what weighing precision was higher weigh ratio mixer.

For achieving the above object, the technical solution adopted in the utility model is as follows:

One is weighed ratio mixer, comprise storage vat, bucket, LOAD CELLS and agitator, described storage vat is positioned at the top of agitator, be provided with by the blowing screw rod of motor-driven rotation bottom described storage vat, described LOAD CELLS is arranged at the both sides of agitator upper inside wall by fixture, the outwardly directed suspension arm of transverse direction that described bucket is provided with by both sides, upper end hangs on LOAD CELLS, the lower surface of described suspension arm is pressed on the top of LOAD CELLS, and the bottom of described agitator is provided with agitating device.

As a kind of preferred version, the bottom of described bucket is provided with the baiting valve controlled to agitator blowing.

As a kind of preferred version, the below of described agitator is provided with compound storage barrel, is provided with baiting valve between described agitator and compound storage barrel.

As a kind of preferred version, described storage vat lower end is provided with vomit pipe, and the charging aperture of described vomit pipe is communicated with agitator, and described charging aperture is positioned at the top of bucket, and described blowing screw rod is arranged in vomit pipe.

As a kind of preferred version, described vomit pipe is obliquely installed upward.

As a kind of preferred version, described storage vat is at least two.

The utility model is by adopting upper above technical scheme, compared with prior art there is obvious advantage, specifically, LOAD CELLS is fixed on the both sides of agitator upper inside wall by fixture, the outwardly directed suspension arm of transverse direction that described bucket is provided with by both sides, upper end hangs on LOAD CELLS, simplifies the structure of equipment, reduces the manufacturing cost of equipment, avoid the interference of the heavy result of other symmetrical configuration simultaneously, improve the precision that plastic material is weighed.Simultaneously, blowing screw rod is provided with bottom storage vat, weighed to bucket by the rotation blowing of screw rod, the stability of blowing can be improved, blowing screw rod has the motor pattern controlling blowing speed, control blowing precision high, the speed of blowing can be controlled according to different situations, when showing weight close to preset value, reducing after dispensing speed can avoid reaching preset value still has more material also not drop to the situation of hopper of weighing, further increase the precision of weighing, ensure that the accurate of Raw Material Blending Ratio, and then improve the quality of the product that injection moulding is produced.

Detailed description of the invention

For more clearly setting forth architectural feature of the present utility model, technological means and the specific purposes reached thereof and function, below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:

As depicted in figs. 1 and 2, one is weighed ratio mixer, comprise storage vat 10, bucket 30, LOAD CELLS 33 and agitator 20, described storage vat 10 lower end is provided with the vomit pipe 13 arranged slightly to surface thereof, the charging aperture of described vomit pipe 13 is communicated with agitator 20, and described charging aperture is positioned at the top of bucket 30, be provided with the blowing screw rod 11 being driven rotation by motor 12 in described vomit pipe 13, by the rotation of blowing screw rod 11 plastic material in storage vat 10 shifted onto bucket 30 from the vomit pipe 13 tilted and weigh.

Described LOAD CELLS 33 is arranged at the both sides of agitator 20 upper inside wall by fixture 34, the outwardly directed suspension arm 32 of transverse direction that described bucket 30 is provided with by both sides, upper end hangs on LOAD CELLS 33, the lower surface of described suspension arm 32 is pressed on the top of LOAD CELLS 33, and the bottom of described bucket 30 is provided with the baiting valve 31 controlled to agitator 20 blowing.By arranging suspension arm 32 in the both sides of bucket 30, simplifying the mounting structure of equipment, reducing the manufacturing cost of equipment, by this simple designs, decrease the interference of other symmetrical configuration amounts, also make weighing result more accurate.

The lower end of described agitator 20 is provided with agitating device 21, and bottom is provided with baiting valve 22, after stirring completes, opens baiting valve 22, and compound falls into the compound storage barrel 23 of below.
