Embodiment

[0042] The invention provides a method for making paper trays, aiming to solve the problems of high waste rate in manual paper trays and high cost and large occupied space in machine-made paper trays. The process of the present invention is mainly divided into several major steps of corrugated cardboard processing, paper tray making, and packaging, which are respectively as follows:

[0043] 1. Corrugated cardboard processing

[0044] First of all, choose corrugated cardboard with 3 layers and C-type corrugation as the surface of the paper tray.

[0045] Then, a number of corrugated cardboards of the same size and specification are stacked sequentially in the order of alternating front and back, and the stacking height does not exceed 1m (usually 5-10 cardboards are stacked). Then press the stacked corrugated cardboard, the pressure is greater than 1 ton, and the pressing time is more than 7 days. After pressing, let it stand naturally for more than 3 days, and then select q...

Abstract

The invention discloses a method for making a paper tray, comprising: (1) sequentially placing a paper roll and a cardboard on a positioning mold and positioning them; (2) nailing the corrugated cardboard and the paper roll together, (3) Turn over the corrugated cardboard, continue to place it on the positioning tool and position it, then place another piece of corrugated cardboard on the positioning tool and position it; (4) Put the second corrugated cardboard and paper roll Nail together, and then take it off as a whole from the positioning mold to obtain the paper tray; (5) Insert the support in the gap between the two corrugated cardboards, then press the paper tray, place it naturally, take out the support, And screen qualified products. The invention has the remarkable characteristics of "three lows and one non-occupancy" such as low waste rate of paper trays, low cost, low energy consumption, and no occupation of space. The problem of high cost and large space occupation, and it is more in line with the concept of energy saving and environmental protection.

Description

technical field [0001] The invention relates to the field of paper tray processing, in particular to a method for making a paper tray. Background technique [0002] For the consideration of environmental protection and some other aspects, it has gradually become a mainstream to take up wire-like objects through paper discs. At present, the main production method of the paper plate is manual bonding, that is, foam is used in the middle, foam blocks are placed on the four sides to support the flatness, and then glue is applied on both sides to bond the paper plate. This artificial bonding method not only has the situation that the quality is not uniform, but also the size of the gap between the two disk surfaces of the paper tray is difficult to control, and the scrap rate of the paper tray is higher (may reach more than 20%). At present, there are also paper trays produced by automatic bonding of machines to ensure the control of the size of the gap. However, such machines a...
