Ball-shaped object screening device for package field

Abstract

The invention belongs to the technical field of screening and particularly relates to a ball-shaped object screening device for the package field. The ball-shaped object screening device comprises a first collecting box, a screening pipeline, a second collecting box, a support and a trigger screening plate. In the device, modularization is adopted in the trigger screening plate for screening, a traditional door structure and a swing plate are combined into one, and thus the trigger screening plate is convenient to install compared with a screening device in which a door structure and a swing plate are located on the upper side and the lower side correspondingly. According to the designed screening device, the upper portion of a screening pipeline does not need to be destroyed, the triggerscreening plate is directly installed on two shaft holes formed in the screening pipeline, and the installing cost is reduced. According to the designed screening device, triggering and screening of the device are achieved at the lower side of the screening pipeline, space needing for installing the trigger screening plate is small, and the utilization rate of the screening pipeline is high.

Description

[0001] Technical field [0002] The invention belongs to the technical field of screening, in particular to a spherical object screening device used in the packaging field. Background technique [0003] Nowadays, many items need to be packaged to prevent them from being damaged during handling and transportation, and the items need to be simply classified before packaging; [0004] At present, there is a sorting mechanism, as recorded in Chapter 14 of "Practical Mechanisms and Devices Atlas of Mechanical Design", when spherical objects come down from the hopper, they must pass through a door, which is also the spring lock of the swing door; it meets the standard size The ball will pass directly without touching the gate, but the gate is generally designed on the upper side of the pipe, and the lower side of the pipe is designed with a swing plate. When the oversized ball hits the gate on the upper side, the upper The door will control the swing of the swing plate on the lower...

Problems solved by technology

[0004] At present, there is a sorting mechanism, as recorded in Chapter 14 of "Practical Mechanisms and Devices Atlas of Mechanical Design", when spherical objects come down from the hopper, they must pass through a door, which is also the spring lock of the swing door; it meets the standard size The ball will pass directly without touching the gate, but the gate is generally designed on the upper side of the pipe, and the lower side of the pipe is designed with a swing plate. When the oversized ball hits the gate on the upper side, the upper The door will control the swing of the swing plate on the lower side through the transmission, so that the balls exceeding the standard size will fall into the groove specially equipped with waste products. It will bring inconvenience to the installation of the structure with the size of the screening ball, and it is not easy to arrange in space. It needs to destroy the pipeline to install, the cost is high, and the installation efficiency is low. Therefore, we design a classification that is easy to install, takes up less space, and is low in cost. device is very necessary
