During production, two ends of the material belt are placed on the limiting brackets 431 due to blocking of the limiting brackets 431, so that during descending of the weaving forks 4133, the limiting brackets 431 are arranged to support the material belt and cannot descend along with the weaving forks 4133 to influence weaving operation. In this embodiment, the two material insertion cylinders 4241 are arranged in an inverted eight-letter shape, and respectively drive the material insertion pieces 4242 thereon to insert the two ends of the material belt inwards. The purpose of this design is to make the two ends of the material belt placed on the lower mold 413 in a natural drooping state, so as to facilitate the knitting operation of the lower mold 413.

Further, the Z-axis lifting component 4122 comprises a Z-axis slide rail 41221 arranged on the lower die mounting rack 41213, a second mounting rack 41222 and a second ball screw 41223 penetrating and rotatably arranged on the second mounting rack; the lower die 413 slides along the Z-axis slide rail 41221, and the lower die 413 is provided at an output end of the second ball screw 41223, and the forward and reverse rotation of the second ball screw 41223 causes the lower die 413 to be lifted and lowered relative to the lower die mounting frame 41213, so that the fork heads 41331 of the two knitting forks 4133 are moved up and down alternately.

The working principle of the automatic knitting of the invention is as follows: referring to fig. 15, the specific steps are analyzed as follows:

STEP 1: starting the melting-pressing upper die 42 and the weaving lower die 41 to be in a separated state, the weaving fork I4133 a is positioned above the weaving fork II 4133b and is in a staggered state, and the material belt I with fixed length and a linear state is automatically placed at the upper end of the weaving fork I4133 a through the material belt supply mechanism 50;

STEP 2: the first weaving fork 4133a descends along the Z-axis direction, meanwhile, the second weaving fork 4133b retreats along the Y-axis direction, ascends along the Z-axis direction and advances along the Y-axis direction, at the moment, the second weaving fork 4133b is positioned above the first weaving fork 4133a and is in a staggered state, and the first linear material belt is positioned between the second weaving fork 4133b and the first weaving fork 4133 a;

STEP 3: the first weaving fork 4133a rises along the Z axis, so that the fork head 41331 of the second weaving fork 4133b and the first weaving fork 4133a are in a mutually opposite insertion state, and the first linear material belt is in a wavy structural state; then, the second material belt 4133b with fixed length and in a linear state is automatically placed on the first weaving fork 4133a through the material belt supply mechanism 50, at this time, the first material belt with the wave-shaped structure and the second material belt with the linear structure are partially contacted and overlapped, then the melt pressing lug 42331 descends along the Z axis, and the region where the first material belt and the second material belt are partially contacted and overlapped is melt-pressed and bonded through the high-frequency principle;

STEP 4: the first weaving fork 4133a, the second weaving fork 4133b and the first melt-pressed and bonded material belt and the second melt-pressed material belt are completely separated from the limiting part 432 synchronously under the STEP3 state through the synchronous action of the two Y-axis sliding components 4121, and the whole body is moved rightwards to one position under the action of the X-axis transplanting mechanism 411, so that the position of the melt-pressed lug 42331 is unchanged, and at the moment, the position of the melt-pressed lug 42331 on the second melt-pressed material belt is subjected to a dislocation phenomenon; through the synchronous action of the two Y-axis sliding assemblies 4121 along the opposite actions, the first weaving fork 4133a, the second weaving fork 4133b and the first fused and bonded material belt and the second fused and bonded material belt synchronously enter the avoidance groove 43211 of the limiting part 432 correspondingly, and at the moment, the second weaving fork 4133b is positioned above the first weaving fork 4133a and is in a staggered state;

STEP 5: the third strip material in a linear state is placed on the second weaving fork 4133b through the strip material supply mechanism 50, and at the moment, the third strip material in the linear state is overlapped with a local area of the second strip material in a wave-shaped structure state;

STEP 6: the melt-pressing bump 42331 descends along the Z axis, and the area where the third material belt and the second material belt are partially in contact and overlapped is melt-pressed and bonded through the high-frequency principle;

STEP 7: the first knitting fork 4133a retracts along the Y-axis direction, ascends along the Z-axis direction, advances along the Y-axis direction, and is inserted into the fork head 41331 of the second knitting fork 4133 b;

STEP 8: the second weaving fork 4133b descends along the Z axis, so that the third linear material belt is in a wavy structure; subsequently, a strip of material four in a straight line state is placed on the weaving fork one 4133a through the strip feeding mechanism 50, and the flow from STEP1 to STEP8 is repeated once again, so that the honeycomb core structure can be manufactured.
