Automatic elimination mechanism and powder filling machine thereof

Abstract

The invention discloses an automatic elimination mechanism and a powder filling machine thereof. A base shaft sleeve, a servo motor, a plurality of conveying stations, movable sorting assemblies, a rotary tray and a control module are included, wherein the base shaft sleeve is installed on a machine body working table, the servo motor is arranged at the lower end of the base shaft sleeve and is provided with a power main shaft penetrating the base shaft sleeve in a matched manner through a bearing, the conveying stations are annularly arranged on the base shaft sleeve, an input belt and an output belt are reserved between every two adjacent conveying stations, each output belt is provided with an unqualified way of the corresponding adjacent conveying stations and a far qualified way, themovable sorting assemblies are arranged in the unqualified ways, the rotary tray is fixed to the end of the power main shaft, is spaced from the base shaft sleeve, and is provided with a plurality oflimiting bayonets corresponding to the multiple conveying stations, and the control module is in electric connection. The movable sorting assemblies open or close the unqualified ways of the conveyingbelts according to metering information fed back by the control module, so that powder barrels conveyed by the rotary tray are automatically eliminated, qualified products and unqualified products are distinguished, and the prior manual elimination trouble can be avoided.

Description

technical field [0001] The invention belongs to the technical field of powder filling, and in particular relates to an automatic rejecting mechanism and a powder filling machine thereof. Background technique [0002] Milk powder is generally packed in iron cans with good sealing performance. The technology of filling milk powder into iron cans is generally screw metering filling. This filling method is filled by the screw in the filling hopper rotating and extruding the powder. The filling accuracy depends on The pitch of the screw and the helix angle of the helix, the filling accuracy is generally about ±5kg, the filling accuracy is not high, the reason is that the screw material is 304 stainless steel, it is easy to cause linear deformation of the screw during the welding of the helix, and the pitch of the helix is ​​all manual by the worker Caliper measurement, the cumulative error value is large, and the filling stability is not enough, the powder may overflow, the fil...

[0002] Milk powder is generally packed in iron cans with good sealing performance. The technology of filling milk powder into iron cans is generally screw metering filling. This filling method is filled by the screw in the filling hopper rotating and extruding the powder. The filling accuracy depends on The pitch of the screw and the helix angle of the helix, the filling accuracy is generally about ±5kg, the filling accuracy is not high, the reason is that the screw material is 304 stainless steel, it is easy to cause linear deformation of the screw during the welding of the helix, and the pitch of the helix is ​​all manual by the worker Caliper measurement, the cumulative error value is large, and the filling stability is not enough, the powder may overflow, the filling process cannot be accurately controlled, and the filling accuracy is not high

Therefore, after the filling is completed in the later stage, it is necessary to classify the qualified and unqualified products. The qualified products are packaged and collected, and the unqualified products continue to be filled. At present, there is no efficient and automatic mechanism for the classification of qualified and unqualified flats, and most of them are manually measured. Manual classification of screens is time-consuming and labor-intensive
