Abstract

The utility model relates to packaging equipment for automatically metering and filling powder material into big package quantity. A main machine is composed of a power head, a storage room for powder material, a filling barrel and a bag holding mechanism which are fixedly installed on an oblong machine body from top to bottom; a bag beating device is used as a box body, and is independent at one side of the lower side of the filling barrel. The metering part is a combined mode by a volume type metering screw with variable diameter and variable pitch and a pulse digital circuit, and adopts a combined type clutch brake with fast response to control the rotation number and the stopping angular position of the screw. The packed weight is controlled in 1-50 kg, and the precision is 2/1000.

Description

The granular material bottle placer

The utility model relates to the automatic gauge of the big package weight of a kind of granular material and the packaging facilities of can, and it will measure with can and hold for one, once finish, and being particularly suitable for Polywoven Bag, cloth bag etc. is the metering packing of the granular material of packaging bag.

Single station quantitative package machine of flour manufacturer use both at home and abroad is to use the screw rod feeding now, beam scale is made meter outfit, though the producer that has has used electronic scales, but packing is still used old-fashioned packaging facilities, adopt compression packing or directly blanking packing, this manner of packing of weighing is downstairs to use pipeline feeding from past upstairs, the back packing of downstairs weighing, and occupation area of equipment is big; And change nominal titre and adjust extremely inconvenience, the flour amount of flying upward out in the packaging process is very big, and the dust content in the working environment is too high, is easy to cause the dust detonation, and is dangerous.

The purpose of this utility model is to provide a kind of granular material bottle placer, to reach granular material is carried out the automatic gauge packing, can adjust the weight of the granular material of each packaging bag packaging as requested easily, reduce the dust of working space, avoid guaranteeing the cleaning and the safety of working space owing to the excessive detonation that may cause of Dust Capacity.

For this reason, the granular material bottle placer is made up of the main and auxiliaries two large divisions, and main frame comprises unit head, granular material logical sequence, (comprising feed pipe and the part of losing heart), can bucket and folder bag mechanism; Down install and fix successively above the oblong body that constitutes from steelframe, clap bagging apparatus, be independent of a following side of can bucket as a casing; The metering section of main frame is positive displacement reducing, the displacement metering screw mode that combines with Pulse and Digital Circuits, and has adopted quick response combination formula clutch-brake, and the electric control system controls box is installed in frame one side, is operated by the plate face.

Unit head is arranged on the top of complete machine, is a little case of being made by steel plate of oblong, and a side vertically is installed with two abutment shafts of being controlled by magnetic clutch and magnet stopper in the case; Above an imput shaft, drive by belt wheel and V-belt by a motor of the side, top of case; Below one be driven shaft; Connect one with key below the axle and be used for metering screw and rotate the number of turns and should stop the gear of angle position, the pulse count of the number of teeth on the wheel, the number of pairing central angle, automatically controlled counting machine is corresponding one by one; The then coaxial metering screw that is linking the positive displacement of a reducing, displacement again; The upper diameter and the pitch of screw rod are bigger, and in the then less and drum shape can bucket of packing into of the diameter of bottom and pitch, a bucket end is a sieve plate with holes.

In addition, below driven shaft, be with the long wheel navel of a belt wheel between counting gear and displacement, the diameter progressive screw coaxially, and maintain certain interval between driven shaft, the wheel navel is fixed on below the unit head with antifriction-bearing box, and this independent motor of taking turns by opposite side in the unit head drags; Wheel navel bottom is equipped with a fork-shaped agitator, rotates with wheel, stirs the granular material in the granular material logical sequence, makes its even feed, along with the rotation of screw rod, enters the can bucket in sieve plate bleeds packaging bag.

The powder material logical sequence is the conical funnel shape cavity that sheet steel is made, and feed pipe and leakage port are arranged on the plane, top, connects cylindrical can bucket down; The both sides of bucket are provided with the folder bag mechanism of being done control link by the push rod of two atmospheric pressure actuating cylinders, go up the back and clamp sack when packaging bag is enclosed within bucket, and the chuck of folder bag mechanism is two semicircle steel rods, one side the two ends of rod near barrel haul a braided wire belt again; Chuck and control link join, and utilize the promotion of cylinder piston, are controlling opening, drawing in of connecting rod and chuck, reach and clamp sack, and put down the purpose of sack after filling granular material.

The main portion that subsidiary engine is clapped bagging apparatus is contained in below the can bucket in independently rectangular cabinet of a side, it is the net of a rectangular planes grid strip that exterior bag is clapped, two places link with eccentric wheel in the cabinet by rocking arm, connecting rod up and down, rotate by an independent motor band eccentric wheel, bag is clapped reciprocally from bag side made real granular material the bag, so that increase packed capacity.

The accuracy rate of every bag of can weight of granular material bottle placer carries out two giving by the electric-control system counting machine to be put control and guarantees, and adds that load leaf spring structure rapid response type clutch-brake guarantees that positive displacement calculates that screw rod rotates the number of turns and the angle position that should stop meets and gives the numerical value of putting by giving.

This machine is simple in structure, and is easy to maintenance, and floor area is little, and pack speed is fast, the precision height, and nominal quantity can be adjusted arbitrarily and easily; Error can be controlled in about 2 ‰, and granular material is not only flour; Metering packing for granular materials such as other material such as starch, medicinal powder, white sugar all is suitable for.

Now specify its architectural feature by Figure of description and embodiment.
