Plastic bottle cap orientation screening device

Abstract

The invention discloses a plastic bottle cap orientation screening device which comprises a hopper and a chain-plank conveying belt, a push-off plate is fixed above the upper portion of the chain-plank conveying belt, an installing plate is arranged on the right side of the upper portion of the chain-plank conveying belt, a longitudinal stop lever is arranged on the installing plate, and a first screening rail is fixed to the position, below the longitudinal stop lever, of the installing plate. The lower end of the first screening rail abuts against a second screening rail, a height differenceexists between the lower end of the first screening rail and the higher end of the second screening rail, the lower end of the second screening rail communicates with a discharge opening, a stock guide is arranged below the first screening rail, and the upper end of the stock guide is fixedly connected with the installing plate. The lower end of the stock guide is located in the hopper. A partition plate is fixed to the edge of the outer side of the stock guide, a material collecting groove hopper is fixed to the right side of the partition plate, a material leaking opening is formed in the upper portion of the material collecting groove hopper, and a discharge outlet is formed in the partition plate. The plastic bottle cap orientation screening device provided by the invention is simplein structure, stable in operation, capable of being used for fast screening plastic bottle caps according to the orientation, and high in screening accuracy rate.

Description

technical field [0001] The invention relates to a plastic bottle cap screening device, in particular to a plastic bottle cap orientation screening device. Background technique [0002] In the modern pharmaceutical industry, the production and bottling of medicines are realized through highly automated assembly lines, which prevents sanitation problems caused by personnel intervention and improves production efficiency. Among them, when the bottle caps used for bottling enter the assembly line, the orientation of the bottle caps needs to be sorted so that the bottle caps enter the assembly line in the same direction. How to efficiently and accurately sort and adjust the orientation of bottle caps has become the key to improving production efficiency. [0003] For example, the authorized announcement number CN205294305U, and the Chinese patent on the authorized announcement date of 2016.06.08 discloses a sorting device for bottle caps. The conveying mechanism drives the bott...

AI Technical Summary

Problems solved by technology

The sorting device has the following defects: (1) The air ejected by the air injection mechanism generates a lateral thrust to make the bottle caps roll into the screening track, and the air source needs to be connected, which is not only complicated in structure, but also high in cost; (2) ) The circular cover rolls along the screening track at a faster speed or passes through the drain when kicked, causing mis-screening and reducing the screening accuracy
