After starch molecules degrade, they do not cause harm to water, air, or soil. By using appropriate processes to thermoplasticize starch, it can achieve the mechanical properties used to manufacture plastic materials. Using starch containing more than 90% starch, adding other components, and using a co-rotating parallel twin-screw extruder to mix and modify the starch and corresponding components, the starch molecules are altered in structure and disordered, forming starch plastics with thermoplastic properties, which are called thermoplastic starch plastics.

[0032] The geared motor 9 and the electrical control box 10 are installed on the upper right bottom of the base frame 1. The operation of the geared motor 9 and the speed of the geared motor 9 are controlled by the electrical control box 10. The drive sprocket 13 is installed at the output shaft end of the geared motor 9. The drive sprocket 13 is connected to the driven sprocket 12 through the drive chain. The speed of the geared motor 9 is adjusted by the electrical control box 10. The geared motor 9 drives the drive sprocket 13 to rotate. The drive sprocket 13 drives the driven sprocket 12 to rotate through the drive chain.

[0033] like Figures 6 to 8As shown, the drive sprocket assembly 11 includes a drive roller 19 and drive journals 20 and A21 located on both sides of the drive roller 19, and a sprocket 14. The drive journals 20 and A21 are respectively housed in the outer spherical bearings 4 on both sides of the top right end of the base frame 1. The outer spherical bearings 4 on both sides of the top right end of the base frame 1 support and position the drive sprocket assembly 11. The end of the drive journal 20 of the drive sprocket assembly 11 is provided with a keyway 22. The driven sprocket 12 is connected to the end of the drive journal 20 by a key and the keyway 22. The drive journals 20 and A21 of the drive sprocket assembly 11 are respectively connected to the sprocket 14 through a flat key 15. The sprocket 14 is provided with positioning screw holes 17 for installing positioning screws. Pins are used to prevent the sprocket 14 from shifting. The chain steel wire 6 includes a steel wire and a chain. Chains are provided on both sides of the steel wire. The sprockets 14 on both sides of the drive sprocket assembly 11 are respectively connected to the chains on both sides of the chain steel wire 6 at their respective locations. The drive rollers 19 of the drive sprocket assembly 11 are connected to and support the steel wire of the chain steel wire 6 at their respective locations. The driven sprocket 12 rotates, causing the sprockets 14 and drive rollers 19 on both sides of the drive sprocket assembly 11 to rotate synchronously and in the same direction. The sprockets 14 on both sides engage the chains on both sides of the chain steel wire 6 at their respective locations. The sprockets 14 and drive rollers 19 on both sides drive the chain steel wire 6 located above to move from left to right, while the chain steel wire 6 located below moves from right to left.

[0034] like Figure 4 and 5 As shown, the sprocket assembly 5 includes a roller 18, journals 16 on both sides of the roller 18, and a sprocket 14. The journals 16 on both sides of several sprocket assemblies 5 are respectively set in the corresponding outer spherical ball bearings 4 on the top sides of the base frame 1 and the vertical supports 23 on both sides of the base frame 1. The several sprocket assemblies 5 are supported and positioned by the corresponding outer spherical ball bearings 4. The journals 16 on both sides of the sprocket assembly 5 are connected to the sprocket 14 through flat keys 15. The sprocket 14 is provided with positioning screw holes 17 for installing positioning screws to prevent the sprocket 14 from moving. The sprockets 14 on both sides of the sprocket assembly 5 are respectively connected to the chains on both sides of the chain steel wire 6 at their respective locations. The rollers 18 of the sprocket assembly 5 are connected to and support the steel wire of the chain steel wire 6 at their respective locations. When the chain steel wire 6 moves, it drives the several sprocket assemblies 5 to rotate synchronously. The strip-shaped starch plastic output from the extruder head of the co-rotating parallel twin-screw extruder is extruded onto the upper left end of the upper chain steel wire 6 of the steel wire air-cooled conveyor. The upper chain steel wire 6 supports the molten strip-shaped starch plastic, and the molten strip-shaped starch plastic moves from left to right along with the upper chain steel wire 6.

Several axial flow cooling fans 8 are respectively installed on the top of the corresponding axial flow fan brackets 7. Several axial flow cooling fans 8 are respectively set above the chain steel wire 6. The operation of the axial flow cooling fans 8 is controlled by the electrical control box 10. The axial flow cooling fans 8 can cool and shape the molten strip starch plastic that moves with the chain steel wire 6 above, and at the same time achieve the effect of cold air drying on the surface of the material. The chain steel wire 6 above transports the cooled and shaped strip starch plastic to the strip pelletizer for cutting and granulation.

[0036] The functions of the steel wire strip air-cooled conveyor are as follows:

[0037] The electrical control box 10 starts the geared motor 9, which drives the driven sprocket 12 to rotate via the drive sprocket 13 and drive chain. The driven sprocket 12 drives the drive sprocket assembly 11 to rotate, which in turn drives the upper chain steel wire 6 to move from left to right, while the lower chain steel wire 6 moves from right to left. The electrical control box 10 also starts several axial flow cooling fans 8, extruding strip-shaped starch plastic from the extruder head of the co-rotating parallel twin-screw extruder onto the upper left end of the upper chain steel wire 6 on the steel wire air-cooled conveyor. The steel wire of the steel wire 6 supports the molten strip of starch plastic. The molten strip of starch plastic moves from left to right along with the steel wire 6 above. The running axial flow cooling fan 8 cools and shapes the molten strip of starch plastic that moves with the steel wire 6 above. The steel wire 6 above conveys the cooled and shaped strip of starch plastic to the strip pelletizer for cutting and granulation, producing biodegradable starch plastic granules for subsequent product processing. This makes it easier for the thermoplastic starch plastic granules to be stored in a dry environment to prevent them from degrading before being processed into products and affecting the processing performance of the products.
