Problems solved by technology

[0005] The present invention can solve the problem that the existing printing waste is usually collected by bagging. However, there is a large gap after the printing waste is bagged, and the waste cannot be compressed, resulting in the waste volume after bagging. Large, low density, thus increasing transportation costs and other problems

Embodiment Construction

[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0036] Such as Figure 1 to Figure 5 Shown, a kind of printing and packaging waste disposal method comprises the following steps:

[0037] S1. Waste collection: manually collect waste such as carton scraps and packaging films after printing;

[0038] S2. Waste pretreatment: pour the waste collected in step S1 through the feed port 2, and under the action of the high-pressure fan, the waste is sucked into the treatment box 1, and the pretreatment device 3 performs crushing and pretreatment on the waste ;

[0039] S3. Extrusion molding: the waste obtained in step S2 is accumulated in the middle of the treatment box 1 through the blocking mechanism 42. When the thickness of the waste gas accumulation reaches one meter, the electromagnet plate 422 is ...

Abstract

The invention relates to a treatment method for printing and packaging waste, which includes a treatment box, a material inlet, a pretreatment device and a compression device. The treatment box is a rectangular hollow structure, and a material inlet is installed at the right end of the treatment box. A pretreatment device is installed on the side, a compression device is installed on the left side of the processing box, and a suction port is installed at the left end of the processing box, and the suction port is connected with the existing high-pressure suction fan. The present invention can solve the problem that the existing printing waste is usually collected by bagging. However, there is a large gap after the printing waste is bagged, and the waste cannot be compressed, resulting in the waste volume after bagging. Large, low density, thus increasing transportation costs and other problems.

Description

technical field [0001] The invention relates to the field of packaging and printing, in particular to a method for treating printing and packaging waste. Background technique [0002] Environmental protection and rational utilization of resources is an urgent and arduous task. Packaging waste is a source of pollution, but it is also a resource that can be used. At present, the recycling of packaging waste has attracted the attention of countries all over the world, and there are countless research conferences and research materials on packaging waste treatment. In my country, due to the rapid development of the packaging industry, the problem of packaging waste has become increasingly prominent. However, my country has not yet established a scientific and complete waste recycling system, and packaging waste recycling regulations still need to be improved, so it is necessary to pay attention and research. [0003] At present, waste generated after printing and packaging us...
