A honeycomb is a hexagonally arranged structure (as shown in Figure 1), which has a hexagonal opening at one end and the bottom of a closed hexagonal pyramid at the other end. In the field of applied materials, honeycomb materials are world-renowned for their excellent compressive and flexural properties and ultra-light structural characteristics; from a mechanical point of view, the closed hexagonal equilateral honeycomb structure can use the least amount of material compared to other structures. The maximum force is obtained, and when the honeycomb structure is subjected to vertical load, its bending stiffness is almost the same as that of the solid material of the same material and thickness, or even higher, but its weight is 70-90% lighter. Therefore, it is widely used in the field of applied materials.

The plastic honeycomb core in the prior art is formed by molding, which is to hot-press a single layer or several layers of adhesive tape into a corrugated plate with a neat shape with a mold, and then stick it into a honeycomb-shaped blank with resin at an appropriate position. And harden the resin under appropriate temperature and pressure, and finally cut the hardened honeycomb material along the vertical direction of the holes. Or use the upper and lower templates and the mandrel to match and press molding. Many honeycomb-shaped grooves are engraved on the surface of the template, which is used as a fixed mandrel. When pressing, first place the glass cloth on the template and the mandrel to form corrugations. After the adhesive is applied to the vertex of the pressed corrugated blank, the adhesive-coated blanks are stacked so that the vertexes of each two adjacent corrugations are in contact with each other.

STEP4: Through the synchronous action of the two Y-axis sliding components 4121, the braiding fork 1 4133a, the braiding fork 2 4133b and the melt-pressure-bonded material tape 1 and material tape 2 in the STEP3 state are synchronized from the limit The position piece 432 is completely disengaged, and then moved by the X-axis transplanting mechanism 411 to move one position to the right. The position where 42331 is melted and pressed on the second material belt is dislocated; through the synchronous action of the two Y-axis sliding components 4121 along the opposite actions, the first braided fork 4133a, the second braided fork 4133b and the melted pressure The bonded material tape 1 and material tape 2 enter into the avoidance groove 43211 of the limiting member 432 synchronously and correspondingly, at this time, the weaving fork 2 4133b is above the weaving fork 1 4133a and is in a staggered state;

STEP5: Place the linear material belt 3 on the weaving fork 2 4133b through the material belt supply mechanism 50, and at this time, the linear material belt 3 and the wavy material belt 2 have a partial area stack;

STEP6: The melting pressure bump 42331 goes down along the Z axis, and melts and bonds the area where the third and second material strips are partially contacted and overlapped by the high-frequency principle;

STEP7: The first braiding fork 4133a retreats along the Y axis, the Z axis rises, and then advances along the Y axis, and is inserted into the fork head 41331 of the second braiding fork 4133b;

STEP8: The second braiding fork 4133b descends along the Z-axis, so that the material tape 3 in a straight state has a wavy structure; subsequently, the material tape 4 in a straight state is placed on the braiding fork one 4133a through the material tape supply mechanism 50 On, go through the process of STEP1 to STEP8 again, so that the honeycomb core structure can be made.
