A single-servo full-open weighing device

Abstract

The invention discloses a single-servo full-open weighing device, which includes a hopper, an adjustment chamber, an operation cabinet and a discharge bin, the adjustment chamber is located between the input hopper and the operation cabinet, and the operation cabinet It is located between the adjustment chamber and the discharge bin, wherein a buffer bin connected to the hopper is provided in the adjustment chamber, and arc sealing doors are movably connected to both sides of the buffer bin through a rotating shaft. The arc sealing door is adapted to the bottom end of the buffer bin, and the first rotating piece is sleeved on the rotating shaft, and the two ends of the first rotating piece are respectively movably connected with a servo-connected synchronizing rod, and one end of the servo-connected synchronizing rod A second rotating piece is connected, and the second rotating piece is connected with a double-pole reducer arranged on one side of the adjustment chamber through a coupling, and the double-pole reducer is connected with a servo motor. The present invention not only has fast response speed, but also accurately controls blanking, more excellent sealing control, faster blanking, and higher production efficiency.

Description

technical field [0001] The invention relates to the technical field of industrial automation, in particular to a single-servo full-open weighing device. Background technique [0002] Industrial automation is the trend of widely using automatic control and automatic adjustment devices in industrial production to replace manual manipulation of machines and machine systems for processing and production. Under the conditions of industrial production automation, people only indirectly take care of and supervise the production of machines. Industrial automation, according to its development stage, can be divided into: (1) semi-automation: that is, part of it adopts automatic control and automatic device, while the other part is produced by manual operation machine. (2) Fully automated: refers to all processes in the production process, including loading, unloading, loading and unloading, etc., do not require people to directly perform production operations (people only indirectly...

Problems solved by technology

[0003] At present, in the process of industrial automation production, granular products need to be packaged, and in the packaging process, granular products need to be weighed and self-discharged to improve production efficiency. At present, conventional self-discharged materials are controlled and adjusted by cylinders or motors. However, the reciprocating motion of the conventional cylinder is relatively slow, and the precision control is not particularly obvious, and the existing mechanical structure design does not eliminate the influence of the inertia well, so that not only the efficiency is poor, but also the precision is low, so that there is a problem in use. Certain limitations
