Abstract

The invention relates to a symmetrical bottle-pushing positioning weighing mechanism, and comprises an outer bottle-pushing air cylinder, an outer positioning block, an inner positioning block and an inner bottle-pushing air cylinder, wherein, the outer positioning block is fixed on a pushing rod of the outer bottle-pushing air cylinder; the inner positioning block is fixed on a pushing rod of the inner bottle-pushing air cylinder; the outer positioning block and the inner positioning block are arranged at both sides of an electronic scale. The symmetrical bottle-pushing mechanism is adopted, so that when the bottles that are to be filled are inputted to the pre-determined filling position, the bottles are ensured to be disposed at a precise weighing position because the bottle-pushing mechanism can correctly push the bottle bodies on the tray of the electronic scale and can be correctly released; the bottle mouth of the bottles that are to be filled aim towards a dibit filling valve, so that conditions are provided for pre-weighing the empty bottles and for the precise filling of the bottles.

Description

The symmetrical expression bottle pulling and positioning weighing mechanism

Technical field:

The present invention relates to a kind of fixed heavy bottle placer that contains the aqueous material of soft grit, relate in particular to bottle pulling and positioning weighing mechanism wherein.

Background technology:

In industries such as agricultural chemicals, chemical industry, coating, daily-use chemical industry, food, have in many liquid to be filled and all contain particulate matter, the material to be filled that has is a paste, adopt common plunger pump to come very easily jam of can, very easily cause the pump housing inner wall abrasion when especially can contains granule materials, and filling accuracy is not high, for the material that has strict weight to require, the weight can such as can't realize, designed a kind of electronic weighing and loading in person, wherein the symmetrical expression bottle pulling and positioning weighing is to guarantee accurately one of the key mechanism of can of whole bottle placer for this reason.

Summary of the invention:

Goal of the invention of the present invention provides a kind of symmetrical expression bottle pulling and positioning weighing mechanism, and it can be stablized, accurately bottle to be filled be delivered on the pallet of electronic scales.

The bottle of the present invention registration device of weighing, comprise fast-slow two-position filling valve 1, electronic scales 2, an extrapolation bottle cylinder 3, outside fix piece 4, interior locating piece 5 and in push away bottle cylinder 6, outside fix piece 4 is fixed on the push rod of extrapolation bottle cylinder 3, push away on the push rod of bottle cylinder 6 in interior locating piece 5 is fixed on, outside fix piece 4 and interior locating piece 5 are distributed in the both sides of electronic scales 2 symmetrically.

Owing to adopted the symmetrical expression bottle pushing mechanism, when making bottle to be filled import pre-filling position, bottle to be filled is accurately shifted onto on the pallet of electronic scales by bottle pushing mechanism, unclamp then, thereby guarantee that bottle is in accurate weighing positions, and make the bottleneck of bottle to be filled aim at the dibit filling valve, claim empty bottle weight, accurate can that condition is provided for pre-.
