The particles are milky white in appearance and easy to absorb moisture. During the film blowing process, the biodegradable masterbatch can be cooled by air through the cold air ring.

[0003] The existing cooling air ring is fixedly installed on the die head. At this time, the positions of the air holes opened on the cooling air ring are fixed. Therefore, during air cooling, the fixed air holes fix the blowing cooling parts of the film, and there is always a certain distance between adjacent air holes, which leads to uneven air output and uneven cooling of different parts of the film.

Therefore, when air cooling is performed, the fixed air holes fix the blowing cooling parts of the film, and there is always a certain distance between adjacent air holes, which leads to uneven air output and uneven cooling of different parts of the film.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A cooling air ring for biodegradable masterbatch production comprises a base, a ring seat, an air inlet nozzle and air holes. The circular base is rotatably mounted with the ring seat in a trumpet shape. A plurality of air inlet nozzles are mounted at equal angles on the outside of the base. The air inlet nozzles are connected to a fan through a connecting pipe. A plurality of air holes are provided on the inside of the ring seat.

[0007] Preferably, a first seat cavity is defined in the base, and an annular groove communicating with the first seat cavity is defined on the base.

[0008] Preferably, a second seat cavity connected to a plurality of air holes is opened in the ring seat, and an annular clamping seat is arranged on the bottom side of the bottom of the ring seat, and the clamping seat passes through the clamping slot and is located in the first seat cavity.

[0009] Preferably, a sealing ring is provided between the card seat and the inner wall of the top of the first seat cavity.

[0010] Preferably, a seat ring is arranged on the outer side of the ring seat, and external teeth are arranged on the outer side of the seat ring.

[0011] Preferably, a mounting plate is arranged on the outer side of the ring seat, a motor is mounted on the bottom side of the mounting plate, a rotating tooth is mounted on the output end of the motor, and the rotating tooth is meshed with the external tooth.

[0012] The beneficial effect of the utility model is that when air blowing cooling is carried out, the ring seat is rotatably installed with the base through the clamping seat, and the rotating teeth are driven to rotate by the motor to cooperate with the meshing external teeth, thereby driving the ring seat to rotate on the base, driving the ring seat to rotate back and forth to achieve uniform air blowing, and then continuously adjusting the position of the air hole to achieve uniform air blowing cooling, thereby ensuring that the quality of the produced film is excellent.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Specific examples are given below.

[0020] See also Figure 1 to Figure 3 A cooling air ring for the production of biodegradable masterbatch comprises a base 1, a ring seat 2, an air inlet nozzle 3 and air holes 4. The ring seat 2 is rotatably mounted on the circular base 1, and the ring seat 2 is trumpet-shaped. A plurality of air inlet nozzles 3 are mounted at equal angles on the outside of the base 1, and the air inlet nozzles 3 are connected to the fan through a connecting pipe, and a plurality of air holes 4 are opened on the inside of the ring seat 2.

[0022] A sealing ring 10 is provided between the card seat 9 and the top inner wall of the first seat cavity 6 to ensure the sealing performance of the installation between the base 1 and the ring seat 2.

[0023] A seat ring 5 is arranged on the outside of the ring seat 2, and an external tooth 11 is arranged on the outside of the seat ring 5. A mounting plate 12 is arranged on the outside of the ring seat 2. A motor 13 is installed on the bottom side of the mounting plate 12. A rotating tooth 14 is installed on the output end of the motor 13, and the rotating tooth 14 is meshed with the external tooth 11. The rotating tooth 14 is driven to rotate by the operation of the motor 13 and cooperates with the meshing external tooth 11, thereby driving the ring seat 2 to rotate on the base 1, and the ring seat 2 performs reciprocating rotation motion.

[0024] The cooling air ring is installed at the die discharge port of the film blowing machine. When the biodegradable masterbatch is heated and melted and blown into a film through the die and passes through the cooling air ring, the fan works at this time, and the cooling air passes through the air inlet nozzle 3 into the first seat cavity 6 and the second seat cavity 8, and is finally blown out from the air hole 4 to cool the film. During cooling, the motor 13 drives the rotating gear 14 to rotate, and cooperates with the meshing external gear 11, thereby driving the ring seat 2 to rotate on the base 1. At this time, the ring seat 2 rotates back and forth, and the angle of each rotation is the same as the angle between the horizontally adjacent air holes 4, so as to achieve uniform blowing.
