Sichuan Jinzhongde Science and Technology Research Institute has developed a practical invention of a 5-layer co extrusion blown film equipment for grass film blowing method. Involving the preservation of agricultural livestock and forage. Food vacuum packaging. Drug packaging. Aluminum battery packaging. Packaging for military equipment. Packaging for optical electronic products.
The high quality of this device lies in:
1. All domestic components are used to replace the high equipment prices that have long relied on Europe, America, and Taiwan
2. Adopt domestic operating control system and industrial control instrument for thickness gauge. Replace the monopoly technology of Europe and America.
3. The mold and screw are made of advantageous mixed steel with elemental components of molybdenum added. Improve corrosion resistance and service life
4. The whole machine adopts a frame structure. Easy to disassemble and assemble. Convenient transportation.
5. The winding adopts AB double winding surface friction structure. Equipped with online slitting. Waste recycling device
6. The traction adopts a horizontal rotating structure. The flatness of the film is uniform.
7. The equipment is efficient and energy-saving. High quality and excellent price. Replace imported equipment
8. Automatic adjustment of the wind ring equipped with an online thickness gauge. Try monitoring and adjusting the deviation of film thickness.
The structure is as follows:; S1 consists of 5 extruders placed at a 180 degree angle below the center point of the frame, and different raw materials are fed into the extruders in different proportions. The screen changer enters the composite mold S2 to form a mold base. Circular film bubbles are formed by cooling with wind ring S3. There are three external blowers connected to the chiller S4. One of the blowers blows cold air to inflate the film bubbles. The other one extracts the hot air inside the membrane bubble. There is also one that sends cold air into the air ring. Set the film bubble, fix it with a stable bubble holder S5, monitor the thickness deviation with a thickness gauge S6, and enter the herringbone board S7 vertically upwards. Flatten it into shape and enter the traction rotating device S8. The traction rotating device is provided. Traction bracket. Rotating device. The film passes through a rotating device. Guide roller. Enter the ultrasonic edge correction machine S9 to adjust the left and right deviation. Enter the lower traction S10. Edge cutting. The lower traction is equipped with a rack platform. Traction roller. Tension sensor. Cutting device. Finally, the film is cut and fed into S11 winding. S12 roll up. The winding machine is equipped. Main transmission roller. Flip frame. Cutting device. Spread the flat stick. Control electrical box. Mechanical arm. This device is equipped with a remote IoT monitoring and control system. Capable of handling faults and maintenance remotely.
