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...

The invention discloses a method for manufacturing a paper plate. The method for manufacturing the paper plate comprises the steps of (1) sequentially placing a paper roll and a paperboard on a positioning jig, and positioning; (2) stapling the corrugated board and the paper roll together, and then removing as a whole from the positioning jig; (3) turning over the corrugated board, continuously placing on the positioning jig and positioning, and then placing another corrugated board on the positioning jig and positioning; (4) stapling a second corrugated board and the paper roll together, thenremoving as a whole from the positioning jig, and obtaining the paper plate; and (5) clipping a support in a gap between the two corrugated boards, then pressing and naturally placing the paper plate, taking the support out, and screening a qualified product. The method for manufacturing the paper plate provided by the invention has the remarkable characteristics of 'three low and one no-occupation' such as low paper plate rejection rate, low cost, low energy consumption and no location occupation, and not only solves the problems of high rejection rate existed in the way of manufacturing paper plates by manpower and high cost and large occupation space existed in the way of manufacturing the paper plates by machines, but also is more aligned with the ideas of energy conservation and environment 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...
