[0026] A first air cylinder 2 is fixedly installed on the first support platform 1. The first air cylinder 2 is located between the left template 8 and the right template 17. A first air needle is fixedly installed inside the telescopic rod of the first air cylinder 2. The telescopic movement of the telescopic rod of the first air cylinder 2 drives the telescopic movement of the first air needle, so that the first air needle penetrates into the tail end 22 of the material and brings out the tail end 22 of the material.

[0027] A second air cylinder 14 is fixedly installed at the bottom of the left template 8 through a screw 15. A second air needle is fixedly installed inside the telescopic rod of the second air cylinder 14. The telescopic movement of the telescopic rod of the second air cylinder 14 drives the telescopic movement of the second air needle, so that the second air needle penetrates into the head end 24 of the material and brings out the head end 24 of the material.

[0028] The blowing assembly includes a third air cylinder 16, a fixing plate 7 and a blowing needle. The fixing plate 7 is fixedly installed on the outer surface of the left template 8. The third air cylinder 16 is fixedly installed on the inner surface of the fixing plate 7. A blowing needle is fixedly installed inside the telescopic rod of the third air cylinder 16. The telescopic movement of the telescopic rod of the third air cylinder 16 drives the blowing needle to reciprocate into the blank of the material, blow air to the blank of the material, and form the blank of the material to make a product 23.

The telescopic rod of the fourth air cylinder 5 is locked on the annular bolt of the third connecting piece 20. The reciprocating movement of the telescopic rod of the fourth air cylinder 5 drives the extension and bending of the first connecting rod 19 and the second connecting rod 21. When the blow molding die rotates under the extruder, the telescopic rod of the fourth air cylinder 5 extends to control the straightening of the first connecting rod 19 and the second connecting rod 21, and further control the closing of the left template 8 and the right template 17 to clamp off the blank of the material extruded by the extruder, preparing for the subsequent blowing and forming by the blowing assembly.

[0030] Working principle:

[0031] When the blow molding die rotates below the extruder, the telescopic rod of the fourth cylinder extends to keep the first connecting rod and the second connecting rod in a straight state, so that the left template and the right template are closed to clamp off the blank. The telescopic rod of the third cylinder extends into the blank, and the blowing needle blows air into the blank to blow the blank into shape. Subsequently, the telescopic rod of the first cylinder extends to drive the first air needle to extend into the tail of the material to cut the tail of the material; at the same time, the telescopic rod of the second cylinder extends to drive the second air needle to extend into the head of the material to cut the head of the material. Furthermore, the telescopic rod of the fourth cylinder retracts to bend the first connecting rod and the second connecting rod, so that the left template and the right template are opened. At this time, the telescopic rods of the first cylinder and the second cylinder retract, and the tail and the head of the material fall off. Subsequently, the electromagnetic valve controls to blow air into the first cavity of the right template, and the formed product falls into the predetermined position.
