Through the foregoing solution, for the existing die head of a blown film machine, the insertion of the air inlet 103 and the outlet pipe of the blown film machine is not additionally fixed, so loosening or even falling off of the insertion may occur during use, thereby affecting the subsequent normal use.

[0023] For this specific embodiment, the inner die 102 is located on one side of the outer die 101; the air inlet 103 is communicated with the inner die 102 and is located on one side of the inner die 102; the chassis 104 is arranged on one side of the inner die 102. The inner die 102 cooperates with the outer die 101 to form a die head. The air inlet 103 is used to connect with the air outlet pipe of the blown film machine. For the specific structures of the outer die 101 and the inner die 102, reference can be made to the patent document with the publication number CN212949166U, and no further elaboration will be made here.

[0024] Among them, the two plug-in blocks 106 are respectively fixedly connected to the outer mold 101 and are respectively located on both sides of the outer mold 101; the two mold fitting parts 107 are respectively arranged on both sides of the chassis 104; the assembly pipe 108 is communicated with the air inlet 103 and is located on one side of the air inlet 103; the two fixing structures 109 are respectively located on both sides of the chassis 104 close to the assembly pipe 108; the assembly frame 110 is fixedly connected to the chassis 104 and is located on one side of the chassis 104; the operating part 111 is arranged on one side of the fitting part frame; the pushing plate 112 is fixedly connected to the operating part 111 and is located on one side of the operating part 111; the guiding part 113 is arranged between the assembly frame 110 and the pushing plate 112; the resisting part 114 is arranged on one side of the pushing plate 112. When using the die head, the outer mold 101 is inserted into the mold fitting parts 107 on both sides of the chassis 104 through the two plug-in blocks 106, and the assembly of the outer mold 101 is completed through the mold fitting parts 107, making the assembly of the outer mold 101 and the inner mold 102 more convenient. Subsequently, the air outlet pipe of the blown film machine is inserted into the assembly pipe 108, and the operating part 111 on the assembly frame 110 on both sides of the chassis 104 is twisted to drive the pushing plate 112 to drive the resisting part 114 to resist the air outlet pipe of the blown film machine through the restriction of the guiding part 113, thus completing the auxiliary fixation of the connection between the blown film machine and the die head, and solving the problem that in the existing die head of the blown film machine, the insertion of the air inlet 103 and the outlet pipe of the blown film machine is not additionally fixed, so the insertion may become loose or even fall off during use, thereby affecting the subsequent normal use.

[0025] Secondly, the assembly frame 115 is fixedly connected to the chassis 104 and is located on one side of the chassis 104; the locking bolt 116 is threadedly connected to the assembly frame 115 and is located on one side of the assembly frame 115; the knob 117 is fixedly connected to the locking bolt 116 and is located on one side of the locking bolt 116; the twisting handle 118 is fixedly connected to the knob 117 and is located on one side of the knob 117.

Cooperating with the anti-slip pad 125 to increase the friction force of the abutting contact surface can complete the fixation of the film blowing machine and the die head assembly.

[0029] When using the present utility model, the outer die 101 is inserted into the assembly frames 115 on both sides of the chassis 104 through the two insertion blocks 106. After the insertion blocks 106 are inserted into the assembly frames 115, operate the twisting handle 118 to make the knob 117 drive the locking pin 116 to insert into the interior of the insertion block 106, and the assembly of the die head can be completed, making the assembly of the outer die 101 and the inner die 102 more convenient. Subsequently, insert the air outlet pipe of the blown film machine into the assembly pipe 108, twist the nut 120 to make the operating screw 119 rotate. The rotation of the operating screw 119 drives the telescopic rod 121 to drive the pushing plate 112 to cooperate with the guiding member 113 to expand and contract. The arc-shaped contact seat 124 is driven by the pushing plate 112 to move, so that the arc-shaped contact seat 124 abuts against the air outlet pipe of the blown film machine, and the anti-slip pad 125 is used to increase the friction force of the contact surface, and the auxiliary fixation of the connection between the blown film machine and the die head can be completed, thus solving the problem that for the existing die head of the blown film machine, the insertion of the air inlet 103 and the outlet pipe of the blown film machine is not additionally fixed, so the insertion may become loose or even fall off during use, and further affect the subsequent normal use.
