Combining method and equipment for forming case by using corrugated boards

Abstract

The invention discloses a combining method for forming a case by using corrugated boards. Combining positions of two sides of the corrugated boards are stitched integrally by stitching lines. The invention further discloses combining equipment for processing the corrugated case in a matched manner. The combining equipment comprises a base, an upright column, an upper cross beam and a lower cross beam, wherein the upright column is arranged on the base; the upper cross beam and the lower cross beam are arranged at the upper end of the upright column; a first servo motor and a second servo motor are respectively arranged at one end of the upper cross beam and one end of the lower cross beam; a first transmission shaft, a case stitching needle and a corner presser are arranged on the upper cross beam; a ball screw, a second transmission shaft, a needle pitch pushing block, a pressure plate and a bottom shuttle are arranged on the lower cross beam; the first transmission shaft is connected with the first servo motor and drives the case stitching needle and the bottom shuttle; and the ball screw is connected with the second servo motor and drives the needle pitch pushing block. The corrugated packaging case is stitched by the lines, the combining positions are firm, the corrugated packaging case is environmentally friendly, wide in applicability and convenient to recycle, and the cost of the used stitching lines is low; and meanwhile, by the combining equipment, high-speed stitching of the corrugated packaging case can be carried out, and therefore, production efficiency is improved.

Description

technical field [0001] The invention relates to a method and equipment for combining corrugated cardboard into boxes. Background technique [0002] At present, the joints on both sides of corrugated boxes are generally combined by nail box or glue box. [0003] The principle of the nail box is the same as that of an ordinary stapler. Its disadvantages are: the nails used in the nail box are prone to rust and pollution; it is easy to damage the contents of the box; the cost of the nail is high; strength; use is limited, cartons using iron nails are not allowed to be exported, cannot be placed in cold storage for a long time, and cannot hold food and items that are afraid of being scratched; when waste cartons are recycled and re-pulped for reuse, all Nails cleaned. [0004] The principle of gluing boxes is to use white latex or chemical synthetic glue to bond corrugated cardboard together. The disadvantage is that the glue will open when it is damp; If the combination is n...

[0003] The principle of the nail box is the same as that of an ordinary stapler. Its disadvantages are: the nails used in the nail box are prone to rust and pollution; it is easy to damage the contents of the box; the cost of the nail is high; strength; use is limited, cartons using iron nails are not allowed to be exported, cannot be placed in cold storage for a long time, and cannot hold food and items that are afraid of being scratched; when waste cartons are recycled and re-pulped for reuse, all nails clean

[0004] The principle of gluing boxes is to use white latex or chemical synthetic glue to bond corrugated cardboard together. The disadvantage is that the glue will open when it is damp; If the combination is not good, that is, the peeling and blistering of the surface paper or lining paper and the corrugated paper occurs, it is easy to greatly reduce the strength of the bond, its compressive and ring compressive strength, the geometric dimensions of the carton are unstable, and it is easy to appear after the goods are packed. The phenomenon of tearing from the bonding place; the use is also limited, and it cannot be bonded to cartons and calcium-plastic boxes with plastic film on the surface of corrugated cardboard; at the same time, the adhesive used for gluing boxes is harmful to human health.
