A powder packaging bag crushing and screening machine

Abstract

The invention discloses a powder packaging bag crusher screen which is characterized by comprising a rack (1), a crushing mechanism (2), a screening mechanism (3), a material collecting device, a fan filter (4) and an anti-explosion control box (5), wherein the screening mechanism (3) comprises a screen cage (3.1) obliquely arranged on the rack (1), a workbench (6) is arranged at the relatively high end part of the screen cage (3.1), the crushing mechanism (2) is arranged between the screen cage (3.1) and the workbench (6), and the fan filter (4) is arranged at the end part, far away from the crushing mechanism (2), of the screen cage (3.1). When the powder packaging bag crusher screen is used, a packaging bag just needs to be arranged at a bag feeding hole directly, materials can be shaken out from a shredded bag sufficiently due to the arrangement of the screen cage, and a negative pressure state is kept in the screen cage all the time due to the arrangement of the fan filter, so that harmful dust cannot diffuse to the working environment, and therefore, material recovery rate is high and safety performance is high.

Description

technical field [0001] The invention relates to the technical field of crushers, in particular to a crushing and screening machine for powder packaging bags. Background technique [0002] With the progress of society and the development of science and technology, human labor in all walks of life is gradually replaced by automation equipment. The production of automation equipment has increased production speed and reduced production costs, which is also the trend of modern social development. Packaging bags, boxes or bottles are the main packaging methods for packaging products now. For powder products, packaging bags and bottles are mostly used for packaging. The production cost of bottles is high and the waste of resources is great. Therefore, most of the powder products are now The product is packaged in a bag. In the field of agrochemical production technology, packaging powder pesticides in bags is widely used because of its low cost and convenient use. These bagged pr...

Problems solved by technology

Packaging bags, boxes or bottles are the main packaging methods for packaging products now. For powder products, packaging bags and bottles are mostly used for packaging. The production cost of bottles is high and the waste of resources is great. Therefore, most of the powder products are now The product is packed in a bag

In the field of agrochemical production technology, packaging powder pesticides in bags is widely used because of its low cost and convenient use. These bagged products need to be recycled after they are damaged or expired. At present, the processing method adopted by various manufacturers is to manually cut the packaging bag with scissors, and then pour out the powder for recycling. The disadvantage of this processing method is that the work efficiency is low, and the working environment of the employees is poor. Floating in the air, it is easy to pollute the environment and is not conducive to people's health, especially pesticide products, which are highly dangerous to handle and manual separation of powder and bags is not clean and thorough

[0003] In the prior art, there are some liquid packaging bag crushing and screening machines, the working principle of which is to first cut the liquid packaging bag into pieces, and then separate the liquid from the packaging bag through roller extrusion, but this kind of equipment cannot be used to crush and separate powder Therefore, the processing of powder packaging bags in the prior art mainly relies on manual processing, which is a kind of high degree of automation, simple structure, safe and convenient use, high work efficiency, complete separation, and harmless to human body and atmospheric environment. Powder packaging bag crushing and screening machine urgently needs to be developed
