Description

Technical Field

[0001] The utility model belongs to the technical field of film processing equipment, and in particular relates to an environmentally friendly film blowing device. Background Art

[0002] Plastic film is made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins. The surface tension of plastic film depends on the surface free energy of plastic film, and the surface energy of film depends on the molecular structure of film material itself. Plastic film can be used for food packaging, electrical product packaging, daily necessities packaging, clothing packaging, etc. Film blowing machine is a special machine that heats and melts plastic particles and blows them into film. Its working principle is that the high and low pressure plastics are heated and melted by the extruder, and then compressed air is used to blow them into film bubbles when they are extruded from the die head, and then they are pressed into film by the roller installed above the die head, and then rolled up.

[0003] Since the outlet channel diameter of the feed hopper of the film blowing device gradually becomes smaller, the material is easily blocked during the falling process, affecting the progress of the film blowing work. In addition, since the temperature of the blown film is high, and the herringbone plate of the existing film blowing device does not have a cooling structure, the film shrinkage is inconsistent and wrinkles are formed, which seriously affects the quality of the film. Utility Model Content

[0004] The utility model aims to provide an environmentally friendly film blowing device to solve the technical problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: an environmentally friendly film blowing device, comprising a heating device and a first motor, the heating device is provided with a feed hopper, the feed hopper is provided with an anti-blocking mechanism, the heating device is provided with a conveying device connected to the first motor, the output end of the conveying device is connected with a mold tube, the mold tube is provided with a die head, the outer side of the die head is provided with a support frame, the support frame is provided with a herringbone plate above the die head, and the herringbone plate is provided with a water cooling structure;

[0006] The anti-blocking mechanism includes a second motor and a stirring shaft, the shaft of the second motor is connected to a first gear, the top end of the stirring shaft is sleeved with a second gear, the stirring shaft is located on the central axis of the feed hopper, and stirring blades are arranged on both sides of the bottom of the stirring shaft, and the bottom of the stirring blades extends to the bottom of the inner cavity of the feed hopper;

[0007] The water cooling structure includes a serpentine tube arranged on the surface of the herringbone plate, one end of the serpentine tube is a liquid inlet, and the other end is a liquid outlet. The liquid inlets of the two serpentine tubes are connected by a first shunt tube, and the liquid outlets of the two serpentine tubes are connected by a second shunt tube. The first shunt tube is provided with a liquid inlet pipe, and the second shunt pipe is provided with a liquid outlet pipe.

[0008] Preferably, a fixing frame is fixedly connected to the side wall of the feed hopper, the bottom of the second motor is fixedly connected to the upper surface of the fixing frame, and the stirring shaft passes through the fixing frame and is rotatably connected to the fixing frame through a bearing.

[0009] Preferably, the first gear is rotatably connected to the second gear, and the first gear and the second gear are meshed with each other.

[0010] Preferably, the surface of the herringbone plate is provided with a serpentine groove matching the serpentine tube.

[0011] The environmentally friendly film blowing device of the utility model has the following advantages:

[0012] 1. The utility model starts the second motor so that the first gear drives the second gear to rotate, which in turn drives the stirring shaft to rotate, which in turn drives the two stirring blades to rotate, so that the stirring blades stir the material in the feed hopper. Since the bottom outlet of the feed hopper gradually becomes smaller, the material is kept loose at all times through the stirring of the stirring blades, which is conducive to the rapid passage of the material through the outlet of the feed hopper and can effectively prevent the feed hopper from being blocked.

[0013] 2. Through the setting of the serpentine tube, the coolant is connected to the liquid inlet pipe, so that the coolant flows through the serpentine tube, so that the herringbone plate is in a low temperature state. Therefore, when the blown film contacts the herringbone plate, the film can be fully cooled, which can effectively avoid the generation of serious wrinkles and improve the quality of the blown film.
