Description

Technical Field

[0001] The utility model relates to the technical field of a waste PET bottle screening device, in particular to a waste PET bottle screening device. Background Art

[0002] PET bottles are not only widely used to package carbonated beverages, drinking water, fruit juice, enzymes and tea beverages, etc., and are the most widely used beverage packaging today, but are also widely used in many fields such as food, chemical, and pharmaceutical packaging. PET plastics are widely used in the packaging field. Whether it is packaging film, coils, or beer bottles, PET plastics are used. At present, PET bottles cannot be screened according to the size of the same type of PET bottles, and manual screening is required. However, the workload of manual screening is huge and the screening efficiency is low. Therefore, we propose a waste PET bottle screening device.

[0003] After searching, it was found that a new type of specific gravity separation device for PET bottle recycling was disclosed in the Chinese patent with authorization announcement 202123435053.0, including a frame, a first fan, a second fan, a hopper, a first screening pipe, a second screening pipe, a first connecting pipe, a second connecting pipe, a first conveying mechanism, a second conveying mechanism, a first collecting box and a second collecting box. The first screening pipe and the second screening pipe are provided with an arc-shaped portion in the middle and an opening is provided on the bottom surface of the arc-shaped portion. The first fan is arranged on the frame at the inlet end of the first screening pipe to blow the recovered PET bottles at the inlet end of the first screening pipe to the outlet of the first screening pipe. The second fan is arranged on the frame at the inlet end of the second screening pipe to blow the recovered PET bottles at the inlet end of the second screening pipe to the outlet of the second screening pipe.

[0004] However, the patents in the prior art have the following disadvantages:

[0005] The novel specific gravity separation device for recycling PET bottles can only screen PET bottles according to their weight, but not according to their size. PET bottles of the same size may be screened into different recycling bins due to their different weights. At the same time, the PET bottles cannot be cleaned and dusted during the screening process.
