Description

Technical Field

[0001] This utility model relates to the field of blown film machine technology, and in particular to an environmentally friendly blown film machine. Background Technology

[0002] Film blowing machines heat and melt plastic particles before blowing them into thin films. The freshly blown film is very hot and needs to be cooled. Current film blowing machines directly cool the film by blowing air, causing significant heat waste. Therefore, there is an urgent need to develop an environmentally friendly film blowing machine that facilitates heat recovery and utilization, overcoming current shortcomings and meeting current needs. Utility Model Content

[0003] The purpose of this invention is to provide an environmentally friendly blown film machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An environmentally friendly blown film machine includes an extrusion mechanism, a feeding port, a conveying pipe, a forming mechanism, a machine cover, a hot air duct, a fan, a winding mechanism, a first guide roller, and a second guide roller. The feeding port is installed on the top of the extrusion mechanism, and the outlet end of the extrusion mechanism is connected to the forming mechanism through the conveying pipe. The machine cover is installed on the upper side of the forming mechanism. Multiple first guide rollers are installed on both the left and right sides inside the machine cover. A second guide roller is installed on the top outer side of the machine cover. A fan is installed on the machine cover, and a hot air duct connected to the feeding port is installed on the machine cover. The fan faces the hot air duct.

[0006] Preferably, the extrusion mechanism includes an outer cylinder, a first motor, a spiral auger, and a heating coil. The spiral auger is rotatably connected inside the outer cylinder. The first motor is fixed to the outside of the outer cylinder, and the output shaft of the first motor is fixed to the spiral auger. The heating coil is installed on the outside of the outer cylinder.

[0007] Preferably, a winding mechanism is provided on one side of the machine cover on the ground.

[0008] Preferably, the winding mechanism includes a frame, a second motor, and a winding roller. The second motor is fixed on the frame, and the output shaft of the second motor is fixed to the winding roller.

[0009] Preferably, the molding mechanism includes: a housing, a mandrel, a molding cavity, an air inlet, an air pump, and an air supply pipe. The mandrel is installed inside the housing, and a molding cavity is formed between the housing and the mandrel. An air inlet is provided inside the mandrel. An air pump is installed below the housing on the ground, and an air supply pipe is installed on the air pump and inserted into the air inlet.

[0010] The beneficial effects of this utility model are as follows: In use, this environmentally friendly blown film machine involves adding plastic granules into the feeding port. The granules slowly fall from the bottom of the feeding port into the outer cylinder. A first motor drives a spiral auger to rotate, conveying the plastic granules forward. Simultaneously, an electric heating coil heats and melts the plastic granules. The high-temperature liquid plastic enters the forming cavity through the conveying pipe to form a plastic film preform. Then, an air pump blows air into the plastic film preform to cause it to expand. As the plastic film preform passes upward through the first guide roller, it is gradually compressed and thinned. A person then winds the front end of the film onto the take-up roller, which is driven by a second motor to rotate and wind the film. Simultaneously, a fan blows air onto the plastic film preform to cool it. The heat is carried by the airflow through the hot air duct into the feeding port, preheating the raw material inside, thereby improving heat utilization and making it more energy-efficient and environmentally friendly. In summary, this utility model facilitates heat recovery and utilization, and is more energy-efficient and environmentally friendly. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Specific implementation examples are given below.

[0021] See Figures 1-6 In this embodiment of the utility model, an environmentally friendly blown film machine includes an extrusion mechanism 1, a feeding port 2, a conveying pipe 3, a forming mechanism 4, a machine cover 5, a hot air duct 6, a fan 7, a winding mechanism 8, a first guide roller 9, and a second guide roller 10. The feeding port 2 is installed on the top of the extrusion mechanism 1. The outlet end of the extrusion mechanism 1 is connected to the forming mechanism 4 through the conveying pipe 3. The machine cover 5 is installed on the upper side of the forming mechanism 4. Multiple first guide rollers 9 are installed on both the left and right sides inside the machine cover 5. A second guide roller 10 is installed on the outer side of the top of the machine cover 5. A winding mechanism 8 is set on the ground on one side of the machine cover 5. A fan 7 is installed on the machine cover 5. A hot air duct 6 connected to the feeding port 2 is installed on the machine cover 5. The fan 7 faces the hot air duct 6. A shielding net (not shown in the figure) is installed at one end of the hot air duct 6 inside the feeding port 2. The shielding net can prevent plastic particles from entering the hot air duct 6.

[0022] The extrusion mechanism 1 includes an outer cylinder 101, a first motor 102, a spiral auger 103, and a heating coil 104. The spiral auger 103 is rotatably connected inside the outer cylinder 101. The first motor 102 is fixed to the outside of the outer cylinder 101, and the output shaft of the first motor 102 is fixed to the spiral auger 103. The heating coil 104 is installed on the outside of the outer cylinder 101. When plastic granules enter the outer cylinder 101, the first motor 102 drives the spiral auger 103 to rotate, and the spiral auger 103 conveys the plastic granules forward. At the same time, the heating coil 104 heats and melts the plastic granules.

[0023] The molding mechanism 4 includes: a housing 401, a mandrel 402, a molding cavity 403, an air inlet 404, an air pump 405, and an air pipe 406. The mandrel 402 is installed inside the housing 401, and the molding cavity 403 is formed between the housing 401 and the mandrel 402. An air inlet 404 is provided inside the mandrel 402. An air pump 405 is provided below the housing 401 on the ground, and an air pipe 406 inserted into the air inlet 404 is installed on the air pump 405.

[0024] The winding mechanism 8 includes a frame 801, a second motor 802, and a winding roller 803. The second motor 802 is fixed on the frame 801. The output shaft of the second motor 802 is fixed to the winding roller 803. In use, the front end of the film is wound onto the winding roller 803, and the second motor 802 drives the winding roller 803 to rotate and wind the film.

[0025] Working Principle: In this environmentally friendly blown film machine, plastic granules are added to the feeding port 2. The granules slowly fall from the bottom of the feeding port 2 into the outer cylinder 101. The first motor 102 drives the auger 103 to rotate, conveying the plastic granules forward. Simultaneously, the heating coil 104 heats and melts the plastic granules. The high-temperature liquid plastic enters the forming cavity 403 through the conveying pipe 3 to form a plastic film preform. Then, the air pump 405 blows air into the plastic film preform to expand it. As the plastic film preform passes upward through the first guide roller 9, it is gradually compressed and thinned. The front end of the film is then wound onto the take-up roller 803. The second motor 802 drives the take-up roller 803 to rotate and wind the film. Simultaneously, the fan 7 blows air onto the plastic film preform to cool it. The heat, carried by the airflow, enters the feeding port 2 through the hot air duct 6, preheating the raw material in the feeding port 2, thereby improving heat utilization and making it more energy-efficient and environmentally friendly.
