Description

Technical Field

[0001] This utility model relates to the technical field of corrugated paper, specifically to waterproof corrugated paper with a double corrugated core. Background Technology

[0002] The existing technology for making corrugated cardboard into cartons involves punching the cardboard, then bending it to create creases, and finally assembling the cardboard into a carton. However, in general, a carton requires multiple applications of adhesive tape to form a complete box from folding to shaping.

[0003] Traditional corrugated cardboard boxes lack waterproof and moisture-proof properties, which reduces their functionality and lifespan. Furthermore, the assembly of waterproof corrugated cardboard boxes primarily relies on adhesive to bond the cardboard and paper. However, the amount of adhesive required increases with the size and thickness of the box, and relying solely on adhesive can negatively impact the structural strength of the corrugated cardboard. Summary of the Invention

[0004] The purpose of this invention is to provide a waterproof corrugated paper with a double corrugated core, so as to solve the above-mentioned defects caused by the prior art.

[0005] A double-walled waterproof corrugated paperboard includes a paperboard body. The outer side of the paperboard body includes an upper kraft paperboard. A corrugated paperboard is provided on one side of the upper kraft paperboard. An assembly mechanism is provided on the outer side of the corrugated paperboard. The assembly mechanism positions and glues the corrugated paperboard and the inner partition core to improve the strength of the connection between the corrugated paperboard and the inner partition core. A positioning mechanism is provided on the outer side of the corrugated paperboard. The positioning mechanism performs vertical positioning treatment on the outer sides of the corrugated paperboard, the upper kraft paperboard, and the lower kraft paperboard, improving the edge structural strength of the upper kraft paperboard and the lower kraft paperboard and preventing deformation of the paperboard body caused by external force collision.

[0006] Preferably, the assembly includes corrugated cardboard, curved slots, an inner partition core, an outer glue inlet, double-sided adhesive strips, and a lower kraft paper. Curved slots are provided on both the left and right sides of the corrugated cardboard. The corrugated cardboard is symmetrically arranged on both sides of the inner partition core. The outer side of the inner partition core is provided with equally spaced outer glue inlets. Double-sided adhesive strips are attached to both the left and right sides of the inner partition core. A lower kraft paper is provided directly below the inner partition core.

[0007] Preferably, the inner partition core is connected to the lower kraft paper side by a double-sided adhesive strip provided on one side.

[0008] Preferably, the positioning mechanism includes a vertical insert rod, side adhesive strips, positioning holes, an internal threaded tube, and an external threaded end. The vertical insert rod is symmetrically arranged on both sides of the upper and lower kraft paperboard. An external threaded end is provided on the outer side of the vertical insert rod. An internal threaded tube is connected to the outer side of the external threaded end. Side adhesive strips are symmetrically distributed on the outer side of the internal threaded tube. The positioning holes are equally spaced on the outer side of the corrugated cardboard.

[0009] Preferably, the corrugated cardboard is connected to the vertical insert rod through a positioning hole at the top.

[0010] Preferably, the vertical insertion rod is connected to the internal threaded tube through an external threaded end on the outer side.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The operator uses the vertical inserts on the outside of the lower and upper kraft paperboard to support the inside of the cardboard body, thereby preventing external hard objects from squeezing and damaging the cardboard body. The operator rotates the external thread end of the internal thread tube on the outside of the vertical insert to adjust the height of the internal thread tube, thus allowing adjustment of the height of the internal thread tube and the side adhesive strip.

[0013] 2. The corrugated cardboard on both sides is engaged by the curved grooves on both sides of the inner partition core, thereby assembling the corrugated cardboard with the inner partition core. This increases the structural strength of the cardboard body formed by the corrugated cardboard and the inner partition core, prevents rainwater from directly penetrating the side panels of the corrugated cardboard, and improves the waterproof strength of the corrugated cardboard.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 4 As shown, the double-walled waterproof corrugated paperboard includes a paperboard body 1. The outer side of the paperboard body 1 includes an upper kraft paper 2. A corrugated paperboard 3 is provided on one side of the upper kraft paper 2. An assembly mechanism 8 is provided on the outer side of the corrugated paperboard 3. The assembly mechanism 8 positions and glues the corrugated paperboard 3 and the inner partition core 7 to complete the connection strength between the corrugated paperboard 3 and the inner partition core 7. A positioning mechanism 12 is provided on the outer side of the corrugated paperboard 3. The positioning mechanism 12 performs vertical positioning treatment on the outer sides of the corrugated paperboard 3, the upper kraft paper 2, and the lower kraft paper 15 to improve the edge structural strength of the upper kraft paper 2 and the lower kraft paper 15 and avoid deformation of the paperboard body 1 caused by external force collision.

[0022] In this embodiment, the combined mechanism 8 includes a corrugated cardboard 3, a curved slot 6, an inner partition core 7, an outer glue injection groove 13, double-sided adhesive strips 14, and a lower kraft paper 15. The corrugated cardboard 3 has curved slots 6 on both its left and right sides. The corrugated cardboard 3 is symmetrically arranged on both sides of the inner partition core 7. The outer glue injection grooves 13 are equally spaced on the outer side of the inner partition core 7. Double-sided adhesive strips 14 are attached to the left and right sides of the inner partition core 7. The lower kraft paper 15 is arranged directly below the inner partition core 7.

[0023] In this embodiment, the inner partition core plate 7 is connected to one side of the lower kraft paperboard 15 by a double-sided adhesive strip 14. The inner partition core plate 7 supports the interior of the paperboard, and the double-sided adhesive strip 14 increases the bonding strength of the lower kraft paperboard 15.

[0024] In this embodiment, the positioning mechanism 12 includes a vertical insert 4, side adhesive strips 5, positioning holes 9, an internal thread tube 10, and an external thread end 11. The vertical insert 4 is symmetrically arranged on both sides of the upper kraft paper 2 and the lower kraft paper 15. An external thread end 11 is provided on the outer side of the vertical insert 4. An internal thread tube 10 is connected to the outer side of the external thread end 11. Side adhesive strips 5 are symmetrically distributed on the outer side of the internal thread tube 10. The positioning holes 9 are equally spaced on the outer side of the corrugated cardboard 3. The friction at the assembly point is increased by the side adhesive strips 5 provided on the outer side.

[0025] In this embodiment, the corrugated cardboard 3 is connected to the vertical insert rod 4 through the positioning hole 9 at the top. The positioning hole 9 is used to position the outer side of the vertical insert rod 4, thus completing the assembly of the corrugated cardboard.

[0026] In this embodiment, the vertical insertion rod 4 is connected to the internal thread tube 10 through the external thread end 11 on the outer side. The height adjustment of the internal thread tube 10 is completed by connecting the external thread end 11 on the outer side of the vertical insertion rod 4 to the internal thread tube 10.

[0027] In practical applications, this type of double-walled waterproof corrugated paper includes the following tasks:

[0028] Step 1: The operator first injects the glue directly into the interior of the outer glue tank 13, and then uses the curved slots 6 on both sides of the two sets of symmetrically arranged corrugated cardboard 3 and the inner partition core board 7 to engage the two sides of the corrugated cardboard 3. The glue inside the outer glue tank 13 is used to glue and connect the contact surfaces of the corrugated cardboard 3 and the inner partition core board 7.

[0029] Step 2: The operator attaches the double-sided adhesive strip 14 to both sides of the inner partition core board 7, and then inserts the lower kraft paper 15 and the vertical insert 4 set below the upper kraft paper 2 into the positioning hole 9 opened at the top of the corrugated cardboard 3. The side adhesive strip 5 set outside the vertical insert 4 is pinched and tightened. When the side adhesive strip 5 is inserted into the positioning hole 9, the corrugated cardboard 3 is positioned by unfolding the side adhesive strip 5.

[0030] Step 3: Before inserting the vertical insert 4, according to the thickness of the corrugated cardboard 3, the operator holds the inner thread tube 10 and rotates the outer thread end 11 set on the outside of the vertical insert 4 to adjust the height of the inner thread tube 10, thereby satisfying the adjustment of the height of the inner thread tube 10 and the side adhesive strip 5, and supporting the connection of the inner partition core plate 7 through the side adhesive strip 5.

[0031] Step 4: The operator then attaches one side of the upper kraft paper 2 and the lower kraft paper 15 tightly to the outside of the double-sided adhesive strip 14, thereby completing the bonding of the upper kraft paper 2 and the lower kraft paper 15 to the left and right sides of the inner partition core board 7, sealing the sides of the inner partition core board 7 and the corrugated cardboard 3 to prevent rainwater from directly seeping into the contact between the inner partition core board 7 and the corrugated cardboard 3.

[0032] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
