Single-servo full open weighing device

Abstract

The invention discloses a single-servo full open weighing device. The single-servo full open weighing device comprises a feed hopper, an adjustment chamber, an operation cabinet and a discharge chamber. The adjustment chamber is located between the feed hopper and the operation cabinet. The operation cabinet is located between the adjustment chamber and the discharge chamber. A slow storage chamber communicating with the feed hopper is arranged in the adjustment chamber. The two sides of the slow storage chamber are movably connected with circular arc-shaped sealing doors through rotary shafts. The circular arc-shaped sealing doors are matched with the bottom end the slow storage chamber. Each rotary shaft is sleeved with a first rotary sheet. The two ends of the first rotary sheet are movably connected with servo connection synchronous rods correspondingly. One ends of the servo connection synchronous rods are connected with the second rotary sheet. The second rotary sheet is connected to a bipolar speed reducer arranged on one side of the adjustment chamber through a coupling. The bipolar speed reducer is connected with a servo motor. The single-servo full open weighing device has the advantages of being high in response speed, accurate in discharge control, more remarkable in sealing control, faster in discharge and higher in 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 can be divided according to its development stage: (1) Semi-automation: that is, part of it uses automatic control and automatic devices, while the other part is produced by manually operated machines. (2) Full automation: 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 take ...

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
