Problems solved by technology

For example, when a weighing hopper capacity of 1000g of a certain material is used to hold 500g of the same material, it will cause an increase in the drop between the material door and the weighing hopper when the packaging scale feeds, so it is necessary to estimate the time to close the material door in advance time
And this estimate is the main reason for the weighing error of the packaging scale.

Embodiment 1

[0051] A packing scale feeding device in this embodiment includes a feeding pipe, a feeding door and an air cylinder arranged in the feeding housing. according to figure 1 and figure 2 It can be seen from the front view and the top view that the feeding pipe 1 and the material door 2 are located in the same vertical direction, and the cylinders 31, 32 are located on the side of the feeding pipe 1 and the material door 2. A first rotating shaft 5 passes through the feed hopper shell 4 between the feed pipe 1 side and the cylinders 31 , 32 sides, and is hinged on the feed hopper shell 4 . Simultaneously, a second rotating shaft 6 positioned at the feeding pipe 1 side is provided, and a bearing seat 61 is fixedly arranged on the outer surface of the outermost feeding pipe 11 by means such as welding, and the second rotating shaft 6 is fixedly connected to the material gate 2. And it is hinged in the bearing seat 61 to realize the hinged connection between the feeding pipe 1 an...

Abstract

The invention provides a packaging scale feeding device. The packaging scale feeding device comprises a feeding hopper, a material door, a driving unit and a transmission unit; the feed hopper comprises at least two layers of feed pipes, and the feed pipe at the outermost layer of can move up and down; the transmission unit is respectively connected with the feeding pipe at the outermost layer andthe material door, and the telescopic height of the material door is equally adjusted according to the telescopic height of the feeding pipe at the outermost layer; and the driving unit is connectedwith the transmission unit and is linked with the material door to open and close through the transmission unit. By means of the packaging scale feeding device, weighing errors caused by overlarge drop from the material door to a scale hopper when a packaging scale is fed can be avoided, and feeding and weighing precision control is guaranteed.

Description

technical field [0001] The invention relates to weighing measurement, in particular to a packing scale feeding device. Background technique [0002] Automatic packaging scales are mechatronic equipment that can be used for accurate and rapid weighing and bagging of granular and powdery materials, and are widely used in grain, feed, chemical and other fields. Its basic working principle is that the meter controls the feeding of the feeder. After the material is added to the scale hopper through the feed pipe, the sensor hanging on the scale hopper feeds back the weight signal to the meter, and then the meter outputs various weights according to the preset program. Control instructions to perform cyclic work. [0003] The current feeding device of the packaging scale has a scheme of setting two layers of material doors inside and outside. When discharging and weighing, firstly, the inner and outer layers of material doors are simultaneously opened to discharge materials. Wh...
