Description

Technical Field

[0001] This invention relates to the field of biodegradable and environmentally friendly plastics technology, specifically to a biodegradable and environmentally friendly plastic, its manufacturing method, and production line equipment. Background Technology

[0002] Biodegradable and environmentally friendly plastics are mainly composed of natural polymer materials or polyesters synthesized by microorganisms, such as plant starch, cellulose, polyhydroxyalkanoates (PHA), and polylactic acid (PLA). Under specific environmental conditions, such as suitable humidity and temperature, these materials can be decomposed by microorganisms in nature into harmless substances such as carbon dioxide, water, and biomass, ultimately returning to the ecological cycle. With continuous technological advancements and market expansion, biodegradable and environmentally friendly plastics will show broad application prospects in various fields such as food packaging, agriculture, and medical devices. At the same time, as an important technology for sustainable development, they will play a significant role in reducing dependence on petroleum resources, reducing environmental pollution, and promoting a circular economy. In the future, with further reductions in production costs and continuous optimization of performance, biodegradable and environmentally friendly plastics are expected to become the mainstream material to replace traditional plastics, contributing significantly to solving the global plastic pollution problem.

[0003] The following shortcomings still exist in practical use:

[0004] 1. If the feed is too much or too little, the mixer will be unable to mix according to the designed formula ratio, resulting in uneven composition or unstable quality of the final product. This may affect the functionality, appearance, or performance of the product. Furthermore, excessive feed may cause the mixer to consume extra energy to process the excess raw materials, thus increasing energy consumption. Conversely, insufficient feed may cause the mixer to operate under load, resulting in low efficiency and increasing the energy cost per unit product. Feed amounts outside the designed range may also cause additional wear and tear on internal components of the mixer, affecting the equipment's lifespan and reliability.

[0005] 2. Furthermore, uneven mixing can result in different components or performance characteristics in the final product, leading to inconsistencies in product quality. This may affect the product's functionality, durability, or appearance. Uneven mixing can also cause some parts of the product to fail to meet design requirements, such as strength, density, or chemical reaction stability, thereby impacting the overall reliability and performance of the product.

[0019] Furthermore, a biodegradable and environmentally friendly plastic is proposed, with the following raw material proportions by weight: 30-50 parts starch, 30-50 parts diammonium hydrogen phosphate, 15-30 parts modified polybutylene succinate, 1-10 parts filler, 1-5 parts coupling agent, 1-10 parts plasticizer, 0.1-2 parts stabilizer, 0.1-1 part antibacterial agent, and 1-5 parts stearate;

[0020] Includes the following steps:

[0021] A. Ingredient preparation: Prepare the specified amounts of each component material as follows:

[0022] B. Dry mixing: Stir the prepared components to ensure that they are fully mixed.

[0023] C. Melting: The mixed raw materials are heated to a molten state;

[0024] D. Pelletizing: The molten raw materials are placed into a pelletizing machine and processed into granular biodegradable plastic pellets.

[0025] Furthermore, a method for producing biodegradable and environmentally friendly plastics is proposed, comprising the following steps:

[0026] Step 1: Select the raw materials and weigh out 30-50 parts of starch, 30-50 parts of diammonium hydrogen phosphate, and 15-30 parts of modified polybutylene succinate. Add them to the mixer, then start the motor and make the mixer rotate at high speed to mix. The mixing time usually needs to be 30-60 minutes for homogenization.

[0027] Step Two: Simultaneously, during the mixing process, 1-10 parts filler, 1-5 parts coupling agent, 1-10 parts plasticizer, 0.1-2 parts stabilizer, 0.1-1 part antibacterial agent, and 1-5 parts stearate need to be added. At the same time, a friction smoothing mechanism is used to ensure that the mixture containing 1-10 parts filler, 1-5 parts coupling agent, 1-10 parts plasticizer, 0.1-2 parts stabilizer, 0.1-1 part antibacterial agent, and 1-5 parts stearate is more evenly distributed on the surface of the raw materials (30-50 parts starch, 30-50 parts diammonium hydrogen phosphate, and 15-30 parts modified polybutylene succinate), reducing agglomeration and clumping. This makes the resulting viscous mixture easier to flow and shape during processing. Furthermore, it utilizes… When used in conjunction with a feeding shielding mechanism and a random dispensing mechanism, the speed and amount of 1-10 parts filler, 1-5 parts coupling agent, 1-10 parts plasticizer, 0.1-2 parts stabilizer, 0.1-1 part antibacterial agent, and 1-5 parts stearate entering the mixer can be adjusted and controlled. Furthermore, it allows the mixture containing 1-10 parts filler, 1-5 parts coupling agent, 1-10 parts plasticizer, 0.1-2 parts stabilizer, 0.1-1 part antibacterial agent, and 1-5 parts stearate to enter the material hopper in different directions and positions, thereby enhancing the uniformity and consistency of the mixture.

[0028] Step 3: After mixing evenly, stop the mixer and discharge the viscous mixture from the discharge port on the outer wall of the mixer to complete the thorough mixing of the components.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] (1) The present invention utilizes the toothed plate groove and the baffle plate to cooperate with each other. The feeding baffle mechanism can accurately control the feeding time and feeding amount of raw material additives, ensuring that the additives are added to the mixer at the right time and in the right proportion. This can avoid the problem of uneven mixing caused by adding the additives too early or too late, thereby improving the mixing efficiency. At the same time, the precise control of feeding can reduce the waste of additives. If too much or too little additives are added, it will affect the mixing effect and product quality. The use of the feeding baffle mechanism can effectively avoid this situation. Furthermore, the feeding baffle mechanism can block other materials inside the mixer during feeding, preventing unnecessary contact and mixing between the additives and these materials, thereby avoiding cross-contamination. This is especially important for products that require high purity or high cleanliness. At the same time, when adding certain powdered additives, without a feeding shielding mechanism, a large amount of dust may be generated, which will not only pollute the production environment, but may also harm the health of operators. The use of a feeding shielding mechanism can effectively reduce the occurrence of dust. In addition, the feeding shielding mechanism can also prevent materials from overflowing outside the mixer during the feeding process, causing chaos and safety hazards on the production site.

[0031] (2) The present invention utilizes the combination of the swivel plate and the inclined plate trough. The random feeding mechanism can ensure that the additives are fed into different positions and directions in the mixer, thereby achieving all-round and multi-angle mixing. This mixing method helps to break the natural stratification and agglomeration of materials, so that the additives are more evenly dispersed in the main material. At the same time, the traditional fixed-point feeding method may cause mixing dead corners inside the mixer, that is, the materials in some areas are difficult to be fully mixed. The random feeding mechanism can reduce or eliminate these dead corners and ensure that all materials can be evenly mixed. In addition, since the random feeding mechanism can accelerate the mutual flow and collision of materials, the mixing process can be accelerated, thus shortening the mixing time to a certain extent. This not only improves production efficiency but also reduces energy consumption and production costs. Furthermore, the comprehensive and multi-angle mixing method helps to enhance the mixing effect, allowing additives to be more fully mixed with the main ingredients. This improved mixing effect helps to improve product quality and stability. Finally, the random dispensing mechanism can prevent materials from accumulating in a certain position during the mixing process, thereby reducing material waste and loss. By randomly dispensing additives, the risk of pollution caused by excessively high local concentrations can be reduced. At the same time, this mixing method also helps to reduce dust flying and material splashing, thereby reducing environmental pollution at the production site.

[0032] (3) This invention utilizes the cooperation of the adapter rod and the friction plate to ensure that the raw material additives are more evenly distributed on the surface of the main raw material during the mixing process through friction smoothing, reducing agglomeration and clumping, thereby improving the uniformity of the overall mixture. In some cases, the additives and the main raw material have different physical properties such as density and particle size, which can easily lead to stratification. The friction smoothing mechanism can effectively reduce this stratification phenomenon and ensure the stability of the mixture. The friction smoothing mechanism can enable the additives to better adhere to the surface of the main raw material, increase the contact area between the additives and the main raw material, thereby optimizing the effect of the additives, such as improving the color, taste, and texture of the product. In addition, for products that require... For additives that require chemical reactions, such as catalysts, the friction smoothing mechanism can promote the contact and reaction between the additive and the main raw material, thereby improving product performance and quality. Because the friction smoothing mechanism can accelerate the dispersion and fusion of additives in the main raw material, it can shorten the mixing time, improve production efficiency, and reduce downtime for adjustment due to uneven mixing, thus improving the continuous operation capability and production efficiency of the equipment. At the same time, the friction smoothing mechanism can reduce the dust and impurities generated by the additive during the mixing process, reducing the impact on product quality. Finally, by ensuring the uniform distribution and effective mixing of additives, it can improve the consistency and stability of the product and reduce batch-to-batch differences.

[0066] Step 1: Select the raw materials and weigh out 30-50 parts of starch, 30-50 parts of diammonium hydrogen phosphate, and 15-30 parts of modified polybutylene succinate. Add them to mixer 1, then start motor 14 and make mixer 12 rotate at high speed to mix. The mixing time usually needs to be 30-60 minutes for homogenization.

[0067] Step Two: Simultaneously, during the mixing process, 1-10 parts filler, 1-5 parts coupling agent, 1-10 parts plasticizer, 0.1-2 parts stabilizer, 0.1-1 part antibacterial agent, and 1-5 parts stearate need to be added. At the same time, the friction smoothing mechanism 4 is used to ensure that the mixture containing 1-10 parts filler, 1-5 parts coupling agent, 1-10 parts plasticizer, 0.1-2 parts stabilizer, 0.1-1 part antibacterial agent, and 1-5 parts stearate is more evenly distributed on the surface of the raw materials (30-50 parts starch, 30-50 parts diammonium hydrogen phosphate, and 15-30 parts modified polybutylene succinate), reducing agglomeration and clumping. This makes the resulting viscous mixture easier to flow and shape during processing. Furthermore, the use of... The material shielding mechanism 2 and the random feeding mechanism 3 work together to adjust and control the speed and amount of filler 1-10 parts, coupling agent 1-5 parts, plasticizer 1-10 parts, stabilizer 0.1-2 parts, antibacterial agent 0.1-1 parts, and stearate 1-5 parts entering the mixer 1. They also enable the mixture containing filler 1-10 parts, coupling agent 1-5 parts, plasticizer 1-10 parts, stabilizer 0.1-2 parts, antibacterial agent 0.1-1 parts, and stearate 1-5 parts to enter the material hopper 11 in different directions and positions, thereby enhancing the uniformity and consistency of the mixture containing filler 1-10 parts, coupling agent 1-5 parts, plasticizer 1-10 parts, stabilizer 0.1-2 parts, antibacterial agent 0.1-1 parts, and stearate 1-5 parts.

[0068] Step 3: After mixing evenly, stop mixer 1 and discharge the viscous mixture from the discharge port 13 on the outer wall of one side of mixer 1 to complete the thorough mixing of the components.

[0069] The following are the complete usage steps and working principle of the above embodiments:

[0070] This device is mainly used for: such as Figure 1 As shown, firstly, the operator prepares the various raw materials to be mixed according to the formula and performs necessary pretreatment, such as crushing, sieving, or pre-processing, to ensure that the raw materials meet the mixing requirements. Then, the pre-treated raw materials are fed into the material hopper 11 of the mixer 1. Next, after the raw materials enter the mixer 1, the actual mixing process begins. The mixer 1 is usually equipped with a rotating agitator 12, which uses a motor 14 to mix, stir, tumble, and fold the raw materials to ensure that all raw materials are fully contacted and mixed. During the mixing process, additives or other specific components can be added to the mixer 1 as needed to improve the performance or processing characteristics of the mixture. Finally, after the mixing process is completed, the mixed product is usually discharged from the mixer 1 through the discharge port 13.

[0071] The feed blocking mechanism 2, used to control the feed flow rate of raw material additives and ensure the accuracy of each feed amount, is used in the following ways:

[0072] like Figures 3 to 4As shown, since a geared motor is externally connected to the output end of one end of the drive shaft 21, the starting of the geared motor will drive the drive shaft 21 to rotate. In addition, a worm 22 is fixedly connected to one end of the drive shaft 21, and the rotation of the drive shaft 21 will synchronously drive the worm 22 to rotate. Furthermore, the worm 22 meshes with the worm wheel 23, so the rotation of the worm 22 will cause the worm wheel 23 to rotate. Secondly, a first ring gear 24 is fixedly connected to the upper end of the worm wheel 23, and a first half-tooth gear 25 is fixedly connected to the upper end of the first ring gear 24. Therefore, the rotation of the worm wheel 23 will jointly drive the first ring gear 24 and the first half-tooth gear 25 to rotate together. Furthermore, the first ring gear 24 meshes with the second ring gear 26, and a second half-tooth gear 25 is fixedly connected to the upper end of the second ring gear 26. The first half-tooth gear 25 rotates, which in turn drives the second ring gear 26 and the second half-tooth gear 27 to rotate. In addition, the first half-tooth gear 25, the second half-tooth gear 27 and the toothed plate groove 29 are partially meshed. Therefore, when the first half-tooth gear 25 and the second half-tooth gear 27 rotate, they will jointly push the toothed plate groove 29 to slide back and forth inside the slide plate 28. Moreover, the lower end of the toothed plate groove 29 is fixedly connected to the baffle plate 210, and the diameter of the baffle plate 210 is adapted to the diameter of the square opening slot opened inside the cover glass plate 15. Therefore, as the toothed plate groove 29 moves, it will drive the baffle plate 210 to block the square opening slot opened inside the cover glass plate 15, thereby controlling the speed and amount of raw material additives added.

[0073] Summary 1: Compared with existing technologies that manually feed excessive or insufficient materials, this mechanism achieves a system where the movement of the toothed plate groove 29 causes the baffle plate 210 to block the square opening slot inside the cover glass plate 15. The feeding baffle mechanism 2 can precisely control the feeding time and amount of raw material additives, ensuring that the additives are added to the mixer 1 at the appropriate time and proportion. This avoids uneven mixing caused by adding additives too early or too late, thereby improving mixing efficiency. At the same time, precise control of feeding can reduce additive waste. If too much or too little additive is added, it will affect the mixing effect and product quality. The use of the feeding baffle mechanism 2 can effectively avoid this situation. Furthermore, the feeding baffle mechanism 2 can block other materials inside the mixer 1 during feeding, preventing unnecessary contact and mixing between the additives and these materials, thereby avoiding cross-contamination. This is especially important for products that require high purity or high cleanliness. At the same time, when adding certain powdered additives, without the feed shielding mechanism 2, a large amount of dust may be generated, which will not only pollute the production environment, but may also harm the health of operators. The use of the feed shielding mechanism 2 can effectively reduce the occurrence of dust. In addition, the feed shielding mechanism 2 can also prevent materials from overflowing outside the mixer 1 during the feeding process, causing chaos and safety hazards on the production site.

[0074] The random dispensing mechanism 3, used to allow raw material additives to enter the material hopper 11 in different directions and positions, is specifically used as follows:

[0075] like Figures 5 to 7 As shown, when the drive shaft 21 rotates, the first bevel gear 31, which is fixedly connected to the outer wall of the drive shaft 21, will rotate synchronously. The first bevel gear 31 meshes with the second bevel gear 32, so the rotation of the first bevel gear 31 will synchronously drive the second bevel gear 32 to rotate. Furthermore, a cam 33 is fixedly connected to the upper end of the second bevel gear 32, so the rotation of the second bevel gear 32 will also drive the cam 33 to rotate. Moreover, the outer wall of the cam 33 and the outer wall of the rocker arm 35 both have protrusions that abut against each other. Therefore, the rotation of the cam 33 will cause the rocker arm 35 to deflect to the left. Furthermore, the hook-shaped end of the rocker arm 35 is engaged in a recessed groove on the outer wall of the rotating ring gear 36. Therefore, when the rocker arm 35 deflects to the left, it will pull the rotating ring gear 36 to rotate counterclockwise. The upper end of the rotating ring tooth 36 is also fixedly connected to the swing plate 37. Therefore, the counterclockwise rotation of the rotating ring tooth 36 will drive the swing plate 37 to rotate counterclockwise as well. In addition, the outer wall of the swing plate 37 is provided with multiple scrapers arranged in a ring. Thus, the rotation of the swing plate 37 will drive the scrapers to rotate as well. This will push the raw material additive placed inside the placement plate 38 to move and be put into the material hopper 11. Furthermore, the interior of the inclined plate trough 39 is also rotatably connected to the swing member 310. Therefore, when the scraper on the outer wall of the swing plate 37 pushes the raw material additive placed inside the placement plate 38 into the wedge-shaped groove in the inclined plate trough 39, the movement of the raw material additive in the wedge-shaped groove will drive the swing member 310 to rotate, thereby allowing the raw material additive to enter the material hopper 11 from different positions of the wedge-shaped groove in the inclined plate trough 39.

[0076] Summary 2: Compared with existing technologies, which may have the possibility of uneven mixing in certain areas, this mechanism achieves a solution where, after the scraper on the outer wall of the tray 37 pushes the raw material additive placed in the placement plate 38 into the wedge-shaped groove in the inclined plate trough 39, the movement of the raw material additive in the wedge-shaped groove will drive the swinging component 310 to rotate, thereby allowing the raw material additive to enter the material hopper 11 from different positions in the wedge-shaped groove of the inclined plate trough 39. The random dispensing mechanism 3 can ensure that the additive is dispensed at different positions and directions in the mixer 1, thereby achieving all-round and multi-angle mixing. This mixing method helps to break the natural stratification and agglomeration of materials, making the additive more evenly dispersed in the main material. At the same time, the traditional fixed-point dispensing method may cause mixing dead corners inside the mixer 1, that is, the material in some areas is difficult to be fully mixed. The random dispensing mechanism 3 can reduce or eliminate these dead corners, ensuring that all materials are evenly mixed. In addition, since the random dispensing mechanism 3 can accelerate the mutual flow and collision of materials, thereby speeding up the mixing process, it can shorten the mixing time to a certain extent. This not only improves production efficiency but also reduces energy consumption and production costs. Furthermore, the comprehensive and multi-angle mixing method helps to enhance the mixing effect, allowing the additives to be more fully mixed with the main ingredients. This improved mixing effect helps to improve the quality and stability of the product. Finally, the random dispensing mechanism 3 can prevent materials from accumulating in a certain position during the mixing process, thereby reducing material waste and loss. By randomly dispensing additives, the risk of pollution caused by excessively high local concentrations can be reduced. At the same time, this mixing method also helps to reduce the occurrence of dust flying and material splashing, thereby reducing environmental pollution at the production site.

[0077] The friction smoothing mechanism 4 is used to ensure that the raw material additives are more evenly distributed on the surface of the main raw material during the mixing process. In specific applications:

[0078] like Figures 8 to 9As shown, when the drive shaft 21 rotates, it synchronously drives the arc-shaped gear 41, which is fixedly installed on the outer wall of the drive shaft 21, to rotate. Furthermore, the arc-shaped gear 41 partially meshes with the rack plate 42. Therefore, when the arc-shaped gear 41 rotates, it synchronously pushes the rack plate 42 to move longitudinally inside the slide rail groove 43. Secondly, when the obstruction post 412, which is fixedly connected to the lower surface of the front end of the rack plate 42, moves to abut the top of the support shaft 411, the obstruction post 412 will press down on the support shaft 411. As a result, the downward movement of the support shaft 411 will push the buckle plate 410 downward, thereby rotating it within the buckle plate 410. The adapter rod 49 of the part will deflect downward to a horizontal state. Furthermore, the end of the adapter rod 49 away from the buckle plate 410 is also fixedly connected to a friction plate 48. Thus, the downward deflection of the adapter rod 49 will push the friction plates 48 to move towards each other. Furthermore, the outer wall of the friction plate 48 is also fixedly connected to a long plate 47, and both sides of the outer wall of the long plate 47 are rotatably connected to connecting rods 46. In this way, when the two friction plates 48 move towards each other, they will simultaneously push the connecting rods 46 to deflect left and right. In summary, the deflection of the adapter rod 49 drives the opposite movement of the friction plates 48 to achieve friction on the surface of the raw material additive placed inside the plate body 38.

[0079] Summary 3: Compared with existing technologies, which often result in agglomeration and clumping when mixing raw materials and additives, this mechanism achieves friction on the surface of the raw material additives placed inside the placement plate 38 by deflecting the adapter rod 49 to drive the opposing movement of the friction plate 48. Through friction and smoothing, the raw material additives can be more evenly distributed on the surface of the main raw material during the mixing process, reducing agglomeration and clumping, thereby improving the uniformity of the overall mixture. In some cases, the additives and the main raw material have different physical properties such as density and particle size, which can easily lead to stratification. The friction and smoothing mechanism 4 can effectively reduce this stratification phenomenon and ensure the stability of the mixture. The friction and smoothing mechanism 4 can make the additives adhere better to the surface of the main raw material, increasing the contact area between the additives and the main raw material. The effect of additives can be optimized, such as improving the color, taste, and texture of the product. In addition, for additives that require chemical reactions, such as catalysts, the friction smoothing mechanism 4 can promote the contact and reaction between the additives and the main raw materials, thereby improving the performance and quality of the product. Since the friction smoothing mechanism 4 can accelerate the dispersion and fusion of additives in the main raw materials, it can shorten the mixing time, improve production efficiency, and reduce the downtime adjustment time caused by uneven mixing, thereby improving the continuous operation capability and production efficiency of the equipment. At the same time, the friction smoothing mechanism 4 can reduce the dust and impurities generated by additives during the mixing process, thereby reducing the impact on product quality. Finally, by ensuring the uniform distribution and effective mixing of additives, the consistency and stability of the product can be improved, and the batch-to-batch differences can be reduced.
