A Stable Feeding Mechanism for Electronic Packaging Scale

Abstract

The invention discloses a stable feeding mechanism of an electronic packing scale. The mechanism comprises a feeing bin and a controller, wherein an outlet is formed in the feeding bin, a crawler conveying mechanism is arranged below the outlet and comprises a tensioning wheel, a driving wheel, a conveying crawler and a driving motor, the tensioning wheel and the driving wheel are wrapped in the conveying crawler, the driving wheel is connected with the driving motor, and a material jumping preventing assembly is arranged on the conveying crawler and comprises a multiple article grooves which are evenly arranged on the outer surface of the conveying crawler. According to the mechanism, materials enter the feeding bin through a feed inlet and fall onto the conveying crawler through the outlet of the feeding bin, feeding speed is adjusted flexibly by controlling the speed of the driving motor, and the material jumping preventing assembly on the conveying crawler can prevent the materials from jumping or rolling after the materials fall into the conveying crawler. Compared with the prior art, the mechanism has the advantages of being simple in structure, low in cost, high in feeding accuracy, good in stability, high in working efficiency and the like.

Description

【Technical field】 [0001] The invention relates to the technical field of weighing tools, in particular to a stable feeding mechanism of an electronic packaging scale. 【Background technique】 [0002] The feeding mechanism is an important part of the electronic packaging scale. There are three feeding methods in the prior art: electromagnetic vibration feeding, screw feeding and self-flow feeding. The electromagnetic vibration feeding method is weighed and measured every time. The amount of feeding in the later stage is easy to control, but the main problem is that it is easy to cause more dust during the feeding process of dry powder materials, and the stability of the material flow is difficult to control; the advantage of the spiral feeding method is that the material flow The stability of the feeder is easy to control, but there are two main problems: one is prone to material blocking, and the other is that the granular material is inevitably crushed, so it is not suitable...

[0002] The feeding mechanism is an important part of the electronic packaging scale. There are three feeding methods in the prior art: electromagnetic vibration feeding, screw feeding and self-flow feeding. The electromagnetic vibration feeding method is weighed and measured every time. The amount of feeding in the later stage is easy to control, but the main problem is that it is easy to cause more dust during the feeding process of dry powder materials, and the stability of the material flow is difficult to control; the advantage of the spiral feeding method is that the material flow The stability of the feeder is easy to control, but there are two main problems: one is prone to material blocking, and the other is that the granular material is inevitably crushed, so it is not suitable for granular materials; the structure of the self-flowing feeding method is simple, but the flow rate of the material is the highest It is not easy to control, and the accuracy of weighing and measurement is difficult to guarantee. There is also a way of conveying by crawlers after self-flowing feeding. Etc., the items are easy to jump on the conveyor belt, thus affecting the feeding efficiency and feeding stability
