Waste cartons refurbishment technology This technology relates to the production of new cartons using old cartons as the main raw material.
The cartons refurbished with this technology are beautiful in appearance and the cost is 30-50% lower than the original new cartons. Compression resistance, burst resistance, and puncture strength are all superior to national standards.
The technology is simple and easy to operate, improves the utilization rate and conversion speed of the carton, and has certain application value and economic benefits.
The present technology relates to the production of paper products in the field of packaging technology, and in particular to a technology for converting and manufacturing new cartons using waste cartons as main raw materials.
At present, the old carton used in the society is processed through chemical pulp and paper and then processed into cartons. This consumes a lot of manpower and material resources.
The purpose of the present technology is to provide a technical method for converting an old carton directly into a new carton without technical pulping and through technological transformation.
This technology is achieved through the following technical measures:
The old cartons are pinned off, the old carton board after nailing is pressed and flattened, the excess part of the old flat carton board that is pressed and flattened is removed by a separator as required, and the old carton board is then brushed with a stitching and splicing part. Hardener layer, then paste a layer of paper, as the inner strip, paste the paper strip wider than the white strip on the outside of the inner strip, as the outer strip, then paste and splicing the outer and inner sides of the old carton board and paste a layer of paper. Inside the paper, the old carton board is converted into a new carton board, and finally the carton board is processed into a new carton by dividing the paper, touching the wire, and cutting corner nail boxes.
The carton reformed with this technology is beautiful in appearance and comparable to the new one. The cost is about 1/2 the cost of the original new type of carton. It is tested by the Quality Supervision, Inspection and Testing Center of Henan Province's packaging cartons, and it is resistant to pressure and heat. The breaking and puncture strengths were respectively 27%, 95%, and 38% higher than the national standard (GB6543-6548-sb). The technology also has the advantages of simple implementation and easy operation.
The specific implementation of this technology is as follows:
a. Disassemble the old cartons by size, remove the pins, store them separately, store about 1700mm in height, press the upper plate with 30kg or so, and press it for 24 hours to refurbish it.
b. Press down the old flat carton board according to the user's needs to divide the paper with a paper separator. If the old carton board is required to dry the carton board, separate the excess part. If the old carton board is smaller than the required carton board, then use The paper machine is divided into one piece! The day box is spliced ​​to another old box so that the dimensions of the required box are initially achieved.
C. Apply a layer of hardener to the felt and splicing areas of the old carton board, and then attach a layer of paper with a width of 40mm-60mm and a weight of 180-300g/m2 as the inner bar, outside the inner bar. Paste a strip of paper with a width of 70-100mm and a weight of 60-150g/m2 as the outer strip. Finally paste and splicing the outer and inner surfaces of the old carton board and paste the one layer paper and the inner paper according to the user's requirements. The carton board is changed to a new carton board.
d. The carton board of the reformed box was separated by a paper separator.
e. Match the carton board that has been cut and neatly according to the user's requirements to the toucher.
f. Cut the corners of the carton board with corner cutters.
g. The carton board after corner cutting is nailed with a nail box machine.
