An electronic packaging scale

Abstract

The invention discloses an electronic packing scale with high weighing accuracy. The electronic packing scale comprises a machine frame, a feeding mechanism, a weighing mechanism and a packing mechanism, wherein a feeding bin is provided with a feeding port and a discharging port, the discharging port comprises a first discharging port body and a second discharging port body which are of different calibers, the outlet of a first feeding auger and the outlet of a second feeding auger are located above a weighing hopper, and a weight sensor is located on the weighing hopper and is connected with a controller. According to the electronic packing scale, the discharging port is composed of the first discharging port body and the second discharging port body which are of different calibers, so that materials entering the corresponding augers are different in amount, the augers are flexibly adjusted by controlling individual drive motors, further the feeding speed is controlled, and multi-level feeding is achieved. Materials are conveyed by a conveying belt to the position of a sewing device, so that a tying opening is sewn, and automatic machining is achieved. Compared with the prior art, the electronic packing scale has the advantages of being simple in structure, low in cost, high in weighing accuracy, high in work efficiency and the like.

Description

【Technical field】 [0001] The invention relates to the technical field of weighing tools, in particular to an electronic packaging scale. 【Background technique】 [0002] The electronic packaging scale is a mechanical and electrical integration product, mainly suitable for granular materials with good fluidity such as: soybeans, corn, etc. The feeding mechanism in the prior art is divided into three types: electromagnetic vibration feeding, screw feeding and self-flowing Feeding, screw feeding and electromagnetic vibration feeding are likely to cause more dust during the feeding process of dry powder materials; self-flow feeding has a simple structure, but the flow of materials is the most difficult to control, and the accuracy of weighing and measurement is difficult to guarantee. There is also a feeding form that is to set a large feeding door and a fine feeding door at the mouth of the hopper. When feeding quickly, the two doors are opened at the same time. When feeding at ...

[0002] The electronic packaging scale is a mechanical and electrical integration product, mainly suitable for granular materials with good fluidity such as: soybeans, corn, etc. The feeding mechanism in the prior art is divided into three types: electromagnetic vibration feeding, screw feeding and self-flowing Feeding, screw feeding and electromagnetic vibration feeding are likely to cause more dust during the feeding process of dry powder materials; self-flow feeding has a simple structure, but the flow of materials is the most difficult to control, and the accuracy of weighing and measurement is difficult to guarantee. There is also a feeding form that is to set a large feeding door and a fine feeding door at the mouth of the hopper. When feeding quickly, the two doors are opened at the same time. When feeding at a slow speed, the large feeding door is closed. When feeding is stopped, the two doors are closed. close at the same time

This feeding method is inconvenient and flexible to adjust the material flow, and it is also prone to material blocking. At the same time, after the weighing is completed, the existing electronic packaging scale needs to manually sew the opening of the bag containing the finished product. The efficiency is low, and the labor cost is also high, so there is a conveyor belt and a sewing machine to complete the stitching of the bag, which improves the degree of automation. However, when the bag falls from the electronic scale, the shape of the bag There are no rules, so it needs to be sorted manually, the production efficiency is low, and because of the different products or the height of the bag, it will cause the height of the sealing line of the bag to be different and skewed, which will affect the outer packaging of the product Aesthetic effect, its production range is narrow
