Technical Field

The utility model relates to a POF thermal contraction membrane blowing machine aircraft nose belongs to film blowing technical field.

Background

Heating and melting solid plastic into liquid, adding the liquid into a die cavity with a certain shape, and cooling to obtain a pipe blank. This equipment, called a blow molding machine, is an essential device in the process of making heat shrink films. Most of existing blow molding machines blow mold a tube blank in an annular film cavity by using compressed air, but a feeding device directly feeds materials at one side of the film cavity, the materials are not uniformly distributed in the film cavity, and the problem of non-uniform thickness of the blown tube blank and a subsequently extruded film exists. In addition, after the tube blank is blown out, the tube blank is guided by two rows of herringbone rollers at present, and is flattened by an extruding roller, and gaps exist between the rollers, so that wrinkles are inevitably generated in the process of flattening by guiding, and the quality of a finished film product is greatly influenced.

The utility model discloses a realize through following technical scheme:

the POF thermal contraction membrane blowing machine head comprises an outer membrane and an inner membrane, a gap between the outer membrane and the inner membrane is called a membrane cavity, a charger is arranged above the outer membrane and the inner membrane, a mounting groove is formed in the top end of the inner membrane, a conical rotating head is arranged above the mounting groove, a motor is arranged inside the mounting groove, the motor is connected with the rotating head through a rotating shaft, a spiral cooling pipe is arranged in the lower portion of the outer membrane, the outer membrane is supported on the ground through a support, a connecting ring is connected to the lower portion of the outer membrane, the lower end of the inner membrane is fixedly connected with the connecting ring, two belt conveyors are arranged in the support through supporting rods.

In the utility model, the material is added on the rotating head, the rotating head rotates at high speed under the driving of the motor, and the material is thrown into the film cavity under the action of centrifugal force, so that the distribution of the material in the film cavity is more uniform, which is beneficial to improving the quality of the final film finished product; the cylinder blank is not easy to generate wrinkles in the process of extruding the film under the guidance of the two belt conveyors, so that the quality of the film is improved.

Further preferably, the top end of the mounting groove is provided with a cover plate through a bolt, and a bearing is arranged between the cover plate and the rotating shaft. Prevent that the material from entering into the mounting groove, also make things convenient for simultaneously to install and maintain the motor.

Preferably, the two ends of the spiral cooling pipe are respectively connected with the water inlet and the water outlet, the water inlet is communicated with the lower end of the spiral cooling pipe, and the water outlet is communicated with the upper end of the spiral cooling pipe. By the design, the upper temperature of the cooling water in the spiral cooling pipe is higher, and the lower the temperature is, the barrel blank is gradually cooled, so that the quality of the final film finished product is improved.

Preferably, the lower end of the connecting ring is provided with a cylindrical drum cloth which plays a role in guiding the drum blank and preventing wrinkles from occurring.

Compared with the prior art, the utility model discloses the beneficial effect who has is:
