Problems solved by technology
[0004] The invention provides a method for recycling and reusing waste cartons, aiming to solve the following problems in the current recycling and reusing of waste cartons: (1) paper fragments and water will sink and accumulate in the cooking tank after mixing and absorbing water At the bottom, the paper fragments accumulated in the inner layer cannot be fully contacted with hot water, and the cooking effect is poor; (2) During the pulp stirring process, the paper materials are gathered by centrifugal force, forming a situation where water and paper materials are separated , reducing the uniformity of the pulp

Embodiment Construction
[0032] 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.
[0033] like figure 1 As shown, this embodiment provides a method for recycling and reusing waste cartons, including the following steps:
[0034] Step 1. Dismantling and cutting cartons: dismantling waste cartons into cardboard, cutting the cardboard to obtain paper fragments.
[0035] Step 2, steaming the paper chips: mixing the paper chips with water, heating and cooking, and stirring to obtain pulp.
[0036] Step 3, drying the pulp to make paper: drying the pulp to obtain a dry material, and flattening the dry material to obtain a new cardboard.
[0037] Among them, step two adopts such as Figure 2 to Figure 6 The waste carton recycling treatment device shown is completed by cooperation. The waste carton recycling treatment device includes a ...

The invention belongs to the technical field of carton recycling and processing, and specifically relates to a method for recycling and reusing waste cartons, comprising the following steps: Step 1, dismantling and cutting cartons: dismantling waste cartons into cardboards, and cutting the cardboards to obtain paper fragments; Step 2, cooking paper chips: mixing paper chips with water, heating and cooking, and stirring to obtain pulp; Step 3, drying pulp to make paper: drying the pulp to obtain dry material, and flattening the dry material to obtain new cardboard. Wherein, the second step is completed with the cooperation of a recycling and reusing processing device for waste cartons. The invention can ensure sufficient contact between paper fragments and hot water, thereby improving the effect of cooking; the invention avoids the separation of paper materials and water, and improves the uniformity of pulp.
Description
technical field [0001] The invention belongs to the technical field of carton recycling and processing, and in particular relates to a method for recycling and reusing waste cartons. Background technique [0002] Carton is the most widely used packaging product. It bears the important responsibility of containing, protecting products and looking beautiful. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc. Cartons have various specifications and models. After a period of use, the carton will be damaged and deformed, making it unusable. If the waste cartons are directly discarded, it will not only pollute the environment but also cause a waste of resources, so it is necessary to recycle the cartons. The recycling and reuse of waste cartons is to disassemble the waste cartons and cut them into paper pieces, then add water to the paper pieces for cooking to form pulp, and then process the pulp into new cardboard. At present, the...
