Problems solved by technology

With the continuous increase of market demand, the scale of corrugated box production is rapidly expanding, and the market competition is becoming increasingly fierce. This requires a comprehensive study of the production process of corrugated boxes, how to effectively reduce the production cost of corrugated boxes, and improve its durability. Safety is particularly important. The existing corrugated boxes are relatively rough in production process, and the strength of corrugated boxes is low. Most of them are used as disposable packaging boxes, which are not economical enough to cause waste and increase the cost of use.

Embodiment 1

[0036] Such as Figure 1-2 As shown, a high-strength corrugated box manufacturing process according to an embodiment of the present invention includes a corrugated cardboard 1, and the corrugated cardboard 1 includes a waterproof board-2 and a fixing board-3 located at the upper end of the waterproof board-2. The side of the fixed plate one 3 away from the waterproof plate one 2 is provided with a reinforcing plate one 4, and the side of the reinforcing plate one 4 away from the fixed plate one 2 is provided with a reinforcing plate two 5, and the reinforcing plate two 5. The side away from the reinforcing plate 4 is provided with a fixing plate 2 6, and the side of the fixing plate 2 6 away from the reinforcing plate 4 is provided with a waterproof plate 2 7. The reinforcing plate 4 is connected with the reinforcing plate 2. A reinforcing mechanism 8 is provided between the two plates 5 .

Embodiment 2

[0038] Such as image 3 As shown, the reinforcing mechanism 8 includes a spherical honeycomb 9, and the spherical honeycomb 9 is composed of a spherical core 10 and ninety partitions 11.

[0039] Such as Figure 3-4 As shown, the spherical center 10 and the ninety partitions 11 form twelve pentagonal pyramid cylinders 12 and twenty hexagonal pyramid cylinders 13 .

Embodiment 3

[0041] Such as Figure 5 As shown, a manufacturing process of a high-strength corrugated box according to an embodiment of the present invention includes the following steps:

[0042] Step 1 S101, pretreatment of fiber raw materials: putting bamboo stalks and wheat straws into a pulverizer and crushing them into scraps, and then grinding the scraps into pulp by a refiner for later use;

[0043] Step 2 S103, enzymatic hydrolysis: cooling the fiber slurry, adding amylase and acid-base regulator;

[0044] Step 3 S105, beating and blending: beating and blending the enzymatically hydrolyzed fibers to obtain uniformly mixed pulp;

[0045] Step 4 S107, making cardboard: Pour the homogeneously mixed slurry after beating and mixing into the cardboard making template, use a paper machine to dehydrate and press to form, and dry, calender, hot press, and curl to obtain base paper;

[0046] Step 5 S109, coating treatment: the base paper is coated by a laminating machine to obtain a water...

Abstract

The invention discloses a manufacturing technology of a high-strength corrugated carton. The manufacturing technology comprises corrugated boards, and the corrugated boards comprise waterproof platesI and fixed plates I positioned at the upper ends of the waterproof plates I; reinforcing plates I are arranged on the sides, away from the waterproof plates I, of the fixed plates I; reinforcing plates II are arranged on the sides, away from the fixed plates I, of the reinforcing plates I; fixed plates II are arranged on the sides, away from the reinforcing plates I, of the reinforcing plates II;and waterproof plates II are arranged on the sides, away from the reinforcing plates II, of the fixed plates II. The manufacturing technology has the beneficial effects that reinforcing mechanisms are added in the reinforcing plates I and the reinforcing plates II in the corrugated boards, strength of the corrugated boards can be improved, and the corrugated boards are prevented from being deformed due to extrusion during the transportation or stacking process; and stress tolerance of the corrugated boards can be improved through a spherical honeycomb structure, extrusion force is decomposedthrough the spherical honeycomb structure when the corrugated carton is extruded, the corrugated carton is prevented from being deformed or damaged due to extrusion, the service life of the corrugatedcarton is prolonged, objects in the corrugated carton are protected, loss is reduced, and economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of cartons, in particular to a manufacturing process of high-strength corrugated cartons. Background technique [0002] Corrugated box is an ideal packaging container, which is light, strong, vibration-absorbing and suitable for mechanized production. It has been used for transportation packaging and sales packaging for many years. Corrugated boxes have won the market for their exquisite appearance and inner good quality. In addition to protecting the goods and facilitating storage and transportation, it also plays the role of beautifying and promoting the goods. With the continuous increase of market demand, the scale of corrugated box production is rapidly expanding, and the market competition is becoming increasingly fierce. This requires a comprehensive study of the production process of corrugated boxes, how to effectively reduce the production cost of corrugated boxes, and improve its durability. Saf...
