Abstract

The utility model provides an automatic powder weighing machine, in particular to a weighing machine for weighting powder materials with a plurality of materials and constituents and conveying the materials to a compression molding work station automatically. The automatic powder weighing machine consists of a mechanical system and an electric control system, and is characterized in that the mechanical system has components adopting the following modes: a material suction device (1) is connected with a material box (2), a filter cloth bag (3) is arranged above the material box (2) in which a rotational agitator (4) is disposed, a material feeder (5) is arranged at the discharge port of the bottom part of the material box, a weighing hopper (6) with a small door is hung on a weighing sensor (7) and disposed under the material feeder (5), a sliding chute (17) is arranged under the weighing hopper (6), and a material cup (8) is fixed on a conveyor chain (10) equidistantly by a gripping head (9) and corresponds to the sliding chute (17). The machine can weight powder materials with a plurality of materials and constituents simultaneously which are fed to the compression work station directly by a conveying apparatus, and the cup is returned automatically, so the weighing machine is very suitable for combining with a multi-position compacting press to form a product line.

Description

Powder automatic weighing machine

Technical field

The utility model belongs to automatic weighing machine, particularly is suitable for the weighing of the many components of multiple material of powder material, and automatic transport is to the compression molding station.

Background technology

The stamping of powder moulding is the mode of production of many mechanical component and commodity, at first will scale be good by weight with powder, and the mould of packing into then.Sometimes need two kinds of moulds of expecting successively to pack into to produce double-layer product.And the weight precision of weighing can directly influence the quality of product and the utilization factor of material.At present mostly powder weighing is all manually finished, and not only labour intensity is big, and dust from flying influences environment, and also there is arbitrariness in weighing error, directly influences product quality.Load weighted powder will be carried with container such as cup, and cup must be returned, and causes the production scene logistics capacity big, complex management, and the manpower waste is serious.

Summary of the invention

The purpose of this utility model provides the automatic weighing of a kind of suitable powder material, dress cup and delivers to the weighing machine of mold pressing station, and can claim the material more than two kinds simultaneously on request.

The purpose of this utility model is achieved in that accompanying drawings is as follows:

A kind of automatic powder weighing machine, form by mechanical system and electric-control system, described mechanical system is formed as follows: suction device 1 is connected with hopper 2, filter cloth bag 3 is equipped with in hopper 2 tops, the stirrer 4 of rotation is housed in the hopper, discharging opening place in the hopper bottom is equipped with feed appliance 5, the bucket 6 that has wicket is hung on the LOAD CELLS 7, and be arranged on the below of feed appliance 5, the below of bucket 6 is provided with lubricating substance groove 17, material cup 8 equidistantly is fixed on the carrier chain 10 by chuck 9, and corresponding with lubricating substance groove 17.

Said suction device 1 adopts induced draft fan.

Said hopper 2 can be columniform, also " U ", and according to several different material of while weighing, hopper can correspondingly be separated into several lattice.

Said feed appliance 5 is made up of drive motor 11, spiral conveyer 12 and material pipe 13, and the diameter of spiral conveyer and pitch can be selected according to the weight of every part of material.

Said feed appliance 5 can increase a minor diameter spiral conveyer 14 again at the output terminal of major diameter spiral conveyer 12.

On the said carrier chain 10, be provided with travel switch 16, and sensor block 15 be housed by the spacing of chuck 9.

Said lubricating substance groove 17 is connected with cylinder 18, can overturn front and back under cylinder 18 promotes, and is provided with collection box 19 below the correspondence of turning over behind the lubricating substance groove 17.

Embodiment

Further specify particular content of the present utility model below in conjunction with the accompanying drawing illustrated embodiment:

Powder material automatic weighing machine of the present utility model is made up of mechanical system and electric-control system.It is characterized in that described mechanical system forms as follows: is claimed the powder end to be drawn onto in the hopper 2, above the hopper filter cloth bag 3 is housed air is discharged by induced draft fan 1.The stirrer 4 that rotation is housed in the hopper prevents the powder layering and is full of discharging opening, feed appliance 5 is housed below discharging opening, feed appliance is to bucket 6 feedings under the control of electric-control system, bucket is hung on the LOAD CELLS 7, when the material weight of carrying reaches setting value, stop feeding, the door of bucket below is opened, with fall 8 li of feed cup of material, weighing enters next circulation.The material cup equidistantly is fixed on the carrier chain 10 by chuck 9, and every title finishes one group of material, and carrier chain can will be expected a glass station of delivering to appointment by instruction, and the operator takes off the material cup and pours powder into mould, and the empty glass of chuck of putting back to original position clamped, and carrier chain is again by new instruction operation.

Hopper 2 can be columniform, also " U ".When several differences of while weighing were expected, U moulding mixture case can correspondingly be separated into several lattice.

Feed appliance 5 is made up of drive motor 11, spiral conveyer 12 and material pipe 13, and the diameter of spiral conveyer and pitch can be selected according to the weight of every part of material.In order further to improve weighing precision, can increase a minor diameter spiral conveyer 14 at the output terminal of major diameter spiral conveyer again and further improve delivery precision.

Material cup 8 is clamped on the chuck 9 of carrier chain 10, on carrier chain 10, by the spacing of chuck 9 sensor block 15 is housed, and chain operation sensor block is during through travel switch 16, and electric-control system is counting and accurate its position that stops of control automatically.

Lubricating substance groove 17 can overturn front and back under the promotion of cylinder 18, when the material of institute's weighing is overproof, turns at electric control system controls lower cylinder 18 action lubricating substance grooves, and material is poured into collection box 19, shaves automatically and removes.Material in the collection box runs up in the sucked back hopper 2 in a certain amount of back.
