Description

Technical Field

[0001] The utility model relates to the technical field of weighing machines, in particular to a linear module suction and unloading structure. Background Art

[0002] The multi-column weighing machine is usually connected to the back of the multi-column packaging machine. The spacing between the columns of the packaging machine is very small, and the structure needs to be compact. The existing high-precision multi-column weighing machine uses the weight of the product itself as the power. The product slides onto the weighing table for weighing. After weighing, the push plate mechanism allows the product to leave the weighing table. The push plate mechanism is independent for each column and is controlled separately. If it is a 10-column weighing machine, 10 sets of push plate mechanisms are required.

[0003] The push plate mechanism is usually located directly below the weighing platform. The push plate mechanism contains a cylinder, a cylinder mounting plate, a guide shaft, a push plate, and connectors. Too many parts will result in the column spacing not being very small; and the compact structure and too many parts are not convenient for later maintenance, and will also increase production costs.
