Background Art

With the increase of per capita disposable income, people's lifestyles are changing, consumption is further expanding, the use of disposable straws is increasing, and the industry market size is showing a growing trend, but the related supporting production equipment has not kept up with the development of the existing market. According to data and research, the current market straw and tubular production equipment has the following problems:

(1) The existing production equipment has only one feed port, which cannot guarantee the stability of the product and cannot meet the needs of new large-scale preparation.

The current disposable straws on the market are mainly degradable straws and edible straws. The production of degradable straws and edible straws requires a variety of materials, and different materials have different physical and chemical properties. The changes and effects that occur at different stages in the extruder are also significantly different. The existing extruder equipment production mode on the market is basically that all materials enter the extruder at the same time, and when materials with different characteristics enter the extruder at the same time, many uncontrollable factors will appear. When the material that needs to be modified at low temperature and the high temperature resistant material are in the low temperature zone together, the high temperature resistant material and the low temperature modified material are mixed together, and the high temperature resistant material does not react or change, but occupies the space and heat of the low temperature modified material. Therefore, the modification time of the low temperature modified material is relatively short, and the heating area is relatively small, which hinders the modification process of the low temperature modified material to a certain extent. The low temperature modified material cannot be completely modified and cannot fully withstand high temperature. Therefore, it is easy to carbonize after entering the high temperature zone, and eventually more defective products are likely to appear; at the same time, it will also greatly reduce the role of the compatible material, resulting in unstable quality of the product in normal production, uneven strength of the tubular material, poor heat resistance and other problems, unable to guarantee the stability of the product, and unable to meet the new preparation method and scientific research experiments. This also indirectly leads to the fact that there has been no preparation method that can produce biodegradable plastic products with stable quality and large-scale production on the market. Therefore, a special processing method is needed to optimize, so that the production raw materials can fully play their role in the extruder and better maintain the characteristics of various materials.

(2) The existing production equipment can only produce a single piece, which cannot give full play to the performance of the production equipment, resulting in low production efficiency and energy waste.

The existing disposable straw and tubular production equipment has a complete production chain and has achieved industrial production. However, the existing extruders are basically single-piece production. Due to various reasons such as economic interest conflicts and technical breakthroughs, the straw and tubular production equipment has not been greatly improved, which ultimately leads to no significant improvement in production efficiency and inability to give full play to the production equipment.

The performance of the equipment is greatly affected, resulting in energy waste.

(3) Existing production equipment can only produce single or two colors, and cannot produce multiple colors or mixed colors.

The existing disposable straws and tubes are single-color or double-color. Disposable straws and tubes with more than two colors have not appeared in the market, nor have they been reported. The existing market is developing rapidly, while the production of disposable straws and tubes is not stable. There is not much improvement, and the original production style is still maintained, but the existing production style is very single, and people have visual fatigue with it. To a certain extent, the promotional appeal of related products using disposable straws and tubes is reduced. The market vitality and prospects are lacking, and it can no longer keep up with the existing market demand. People's consumption concepts have been changing, and the disposable straws and tubes market also needs to make more improvements and adjustments. The market needs more styles and colors of disposable straws and tubes.

(4) Existing tubular production equipment or material granule production equipment can only produce tubular products or material granules alone. To produce tubular products and material granules at the same time, two sets of production equipment are required, which wastes manpower, financial resources, and energy, and takes up space.

In the preparation method for producing tubular objects, the raw materials for producing straws and tubular objects basically require material particles, and straws and tubular objects can also be used as material particles to a certain extent, so tubular objects and material particles complement each other, coexist with each other, and can be used with each other. In the case of only tubular object production equipment, if material particles need to be produced, new production equipment needs to be added. In the case of only material particle production equipment, if tubular objects need to be produced, new production equipment also needs to be added. Adding new production equipment will inevitably increase the use of more sites, energy consumption, labor costs, etc., resulting in certain duplication of investment and superposition of costs, and will also lead to problems such as high energy consumption and high carbon emissions.

(5) In the existing tubular production equipment or material particle production equipment, the temperature of the tubular extruded from the discharge die is relatively high and in a molten state. It needs to be quickly cooled and shaped, otherwise the shape will be deformed and stick together, which will affect normal production. In addition, rapid cooling greatly improves the mechanical properties of tubular products, and packaging and sales also need to be cooled before they can be carried out, so cooling is required. Affected by the market and technical limitations, traditional cooling equipment is mostly conveyors equipped with fans for cooling and cooling. However, the fan cooling time lasts for a long time, the cooling effect is poor, the conveying equipment needs to be long, and the floor space is large, resulting in a large waste of space resources, making the equipment floor space, the number of personnel and the comprehensive energy consumption requirements large, and there are also problems such as high energy consumption and high carbon emissions, which no longer meet the current market industrial production needs.

Biodegradable materials are a feasible and effective way to solve the environmental pollution caused by plastic waste and alleviate the shortage of petroleum resources. Biodegradable materials are mainly made by synthesizing biodegradable polymers through extruders, such as thermoplastic starch plastics, polylactic acid, etc. With the promulgation of the new version of the plastic restriction order, China is expected to become the world's largest consumer market for biodegradable plastics in recent years. The backwardness of production equipment has limited the preparation method of degradable particles to a certain extent. The existing production mode of extruder equipment on the market is basically that all materials enter the extruder at the same time, and when materials with different characteristics enter the extruder at the same time, many uncontrollable factors will appear, which is particularly obvious in the production of material particles. When the low-temperature material and the high-temperature material are mixed and in the low-temperature zone at the same time, the high-temperature material does not react or change, but occupies the space and heat of the low-temperature material. Therefore, the modification time of the low-temperature material becomes relatively shorter, and the heating area becomes relatively smaller. The low-temperature material cannot be completely modified, and the quality is prone to instability, resulting in uneven particle strength and physical

There are problems such as unstable performance, so like the tubular production equipment, it is necessary to fully utilize and maintain the material properties.

The advantages and disadvantages of existing production equipment are listed in Table 1:

In summary, the existing production equipment has only one feed port, and the material can only enter the extruder at one time, which cannot fully utilize the characteristics of different materials, and is prone to problems such as uneven product strength and unstable physical properties. During production, only a single tube can be produced, which limits the production capacity of the extruder, and a single tube can only produce single-color or two-color tubes, and cannot produce multi-color or mixed-color tubes. The production style is single and lacks market publicity appeal.

In the preparation method for producing tubular objects, the production raw materials basically require material particles, and the tubular objects can also be used as material particles to a certain extent. Therefore, the tubular objects and material particles complement each other and coexist with each other. There are many situations in the existing market that require the simultaneous production of tubular objects and material particles, but the existing equipment can only produce tubular objects or material particles alone, which can no longer keep up with the existing market demand.

It is widely used in industry, medicine, catering, daily necessities and various plastics and degradable materials. It is energy-saving, low-carbon and environmentally friendly. The production process is continuous and stable, safe and pollution-free, and is suitable for large-scale industrial production.

(1) The feed inlet module of the present invention is provided with 4 feed inlets, so that materials with different physical properties can enter the specific temperature zone through different feed inlets, giving full play to the physical properties and characteristics of various materials, significantly improving the mechanical properties, heat resistance and physical stability of the product, and facilitating the use and invention of more preparation methods, see Figures 4 and 5. The conventional plastic raw materials used by the existing market screw extruders in the production of plastic tubular objects or plastic particles are single raw materials and are synthetic. They can directly enter the screw extruder from a single feed inlet, be heated and melted, and then be extruded from the screw extruder after becoming molten.

As environmental protection requirements become increasingly stringent, new biodegradable plastics are widely used;

New biodegradable plastics need to be modified due to physical properties and the requirements of end products. The required raw materials include low-temperature materials, modified materials, compatible materials, high-temperature materials and other materials with different physical properties. The low-temperature materials and modified materials need to be mixed and modified to reach a state of withstanding high temperatures and melt and react with the high-temperature materials. Then, during the production process, compatible materials are added for surface modification to increase the dispersibility of the low-temperature materials and their compatibility with the high-temperature materials. Ultimately, the polarity difference between the low-temperature materials and the high-temperature materials is overcome. With the help of the intermolecular bonding force, the low-temperature materials are evenly distributed in the entire high-temperature material system, which promotes the combination of the two incompatible polymers into one, thereby obtaining a stable blend, thereby greatly improving the compatibility and dispersibility of the composite material.

The traditional equipment has only one feed port. When all materials enter the screw extruder through the same feed port, the materials that need to be modified at low temperature and the high temperature resistant materials are in the low temperature area together. The high temperature resistant materials do not react or change, but occupy the space and heat of the low temperature modified materials. Therefore, the modification time of the low temperature modified materials is relatively shortened, and the heating area is relatively smaller, which hinders the modification process of the low temperature modified materials to a certain extent. The low temperature modified materials cannot be completely modified and cannot be fully The plastic cannot withstand high temperatures, so it is easy to carbonize after entering the high temperature zone, and eventually more defective products will appear. At the same time, it will greatly reduce the role of the compatible material, resulting in unstable quality of the product during normal production, uneven strength of the tubular product, poor heat resistance, etc., which cannot guarantee the stability of the product and cannot meet the requirements of new preparation methods and scientific research experiments. This indirectly leads to the fact that there has been no preparation method for stable quality and large-scale production of biodegradable plastic products on the market. Therefore, a special processing method is needed to optimize the production of raw materials so that they can fully play their role in the extruder and better maintain the various materials.

characteristic;

Based on the above reasons, the feed port module of the present invention is provided with 4 feed ports, the low-temperature material enters through the first feed port, the modified material enters through the second feed port, the compatible material enters through the third feed port, and the high-temperature material enters through the fourth feed port. The low-temperature material enters the primary screw extruder through the first feed port, is mixed with the modified material entering through the second feed port, and is mixed with the compatible material entering through the third feed port. After mixing, compatible modification occurs in the low-temperature zone of 70 to 100°C, and the high-temperature temperature resistant to the modified composite material reaches a high-temperature temperature similar to that resistant to the high-temperature material. The modified composite material is mixed with the high-temperature material entering through the fourth feed port, and after mixing, it is matured and melted in the high-temperature zone of 130 to 230°C. Materials with different physical properties enter the specific temperature zone of the primary screw extruder through different feed ports, giving full play to the different characteristics of various materials such as low-temperature materials, modified materials, compatible materials, and high-temperature materials, thereby improving the physical strength and performance of the final product; it has the following beneficial effects:

(1) It solves the problems of uneven product strength and unstable physical properties after different materials enter the extruder at the same feed port. At the same time, it significantly improves the mechanical properties, heat resistance and physical stability of the product with advanced preparation methods, which is conducive to the use and invention of more preparation methods; the experimental research of this patent application found and verified that: taking the modification of PBAT by adding compatible materials as an example, when PBAT is modified by filling starch, the addition of starch causes the crystallization temperature of the blend to shift to the high temperature direction, and the crystallinity decreases accordingly. The addition of compatible materials not only improves the dispersion effect of starch, but also greatly improves the compatibility between starch and PBAT; significantly improves the mechanical properties and glass transition temperature of the modified material, toughens the modification, tensile and impact strength, achieves high filling, reduces the amount of high temperature materials, improves processing rheology, and improves surface finish.

(2) The present invention can produce multiple tubular systems, and each tubular system is processed with 1 to 500 discharge holes. The present invention can concentrate 2 to 16 tubular systems in simultaneous production, greatly improving production efficiency. See Figure 10, which shows 8 tubular systems being produced simultaneously.

When producing plastic tubular products, the existing screw extruders in the market can only produce single pieces, and all supporting equipment can only process single pieces. With the continuous changes in emerging market demand and the international environment, issues such as emission reduction, energy conservation and environmental protection are becoming more and more important. Coupled with the continuous increase in raw material costs, the existing single-piece production of screw extruders can no longer meet market demand.

Based on the above reasons, the present invention is a system for producing multiple tubular objects, and the tubular object system produces 1 to 500 tubular objects. The mold core shaft plate has 1 to 500 mold core shafts evenly fixed in the vertical direction of the plate surface. The first discharge plate, the second discharge plate, the third discharge plate and the discharge mold each have 1 to 500 discharge holes corresponding to them, and 2 to 16 sets of tubular object systems are concentrated for simultaneous production; the tubular object system is provided with an antistatic annular cooling ring sleeve combination, including an antistatic annular cooling ring head mold sleeve and an antistatic annular cooling ring shaping sleeve, and the antistatic annular cooling ring head mold sleeve The first one is set on the discharge mold to control the rapid cooling of the discharge mold. The antistatic annular cooling ring shaping sleeve is set between the discharge mold and the traction system to control the rapid cooling of the output tubular product. The 1 to 500 processed discharge holes are evenly arranged on the discharge mold. With the new production equipment and the new preparation process, the process is as follows: the production material is modified → mixed → matured → melt reaction → antistatic annular cooling ring head mold sleeve → tubular product extrusion → antistatic annular cooling ring shaping sleeve → traction → rotary cutting → sterilization → packaging → obtaining a plurality of tubular products.

It has the following beneficial effects:

①: It solves the problem of limited output of existing tubular production equipment in the traditional market, improves the production efficiency of tubular products, and also improves the utilization rate of production equipment, gives full play to the production capacity of the extruder, reduces production energy consumption, reduces carbon emissions, improves production efficiency, and also improves the utilization rate of production equipment, which is more in line with the market's industrialized production needs and more in line with national requirements in terms of emission reduction, energy saving, and environmental protection.

②: The production capacity that can be achieved by the present invention has been significantly improved and enhanced compared with the traditional production methods in the existing market, solving the problem of the shortcomings of the existing traditional market equipment.

(3) The present invention produces multiple tubular objects and modified material particles simultaneously, which improves the utilization rate of the equipment and greatly improves the production efficiency, as shown in FIG12 :

The existing market screw extruder can only produce tubular objects or material particles. With the increasing requirements for environmental protection, the use of new biodegradable materials is becoming more and more common. The preparation methods of new biodegradable tubular objects all use biodegradable particles. Tubular objects can also be used as material particles to a certain extent. This has led to the need to produce tubular objects and material particles at the same time. Therefore, a new relationship has emerged between tubular objects and material particles, and the two complement each other and coexist with each other. In the case of only tubular object production equipment, if material particles need to be produced, new material particle production equipment needs to be added. In the case of only material particle production equipment, if tubular objects need to be produced, new tubular object production equipment also needs to be added. Adding new production equipment will inevitably increase the use of more sites, energy consumption, labor costs, etc., resulting in certain investment duplication and cost superposition, and will also lead to problems such as high energy consumption and high carbon emissions.

Based on the above reasons, the screw extruder combination module of the present invention is provided with a primary screw extruder, a secondary screw extruder and a tertiary screw extruder, wherein the secondary screw extruder and the tertiary screw extruder are respectively equipped with a tubular system and a granulation system, and can simultaneously produce a plurality of-single multi-color tubular objects and modified material particles. The extruders used in the screw extruder combination module include single-screw extruders, twin-screw extruders and multi-axis screw extruders, etc. According to the preparation requirements of different products, two or three of the single-screw extruders, twin-screw extruders and multi-axis screw extruders are adjusted to be combined.

The present invention can produce multiple tubular objects and modified material particles simultaneously, and has the following beneficial effects: it solves the problem of equipment that needs to produce tubular objects and material particles at the same time. For equipment that produces tubular objects separately and equipment that produces material particles separately, the present invention concentrates the advantages of two types of production equipment, optimizes equipment configuration, reduces the overall floor space, reduces corresponding equipment costs and labor costs, reduces production energy consumption, reduces carbon emissions, improves production efficiency, and also improves the utilization rate of production equipment, which is more in line with the market demand for industrialized production and more in line with national requirements in terms of emission reduction, energy conservation, and environmental protection.

(4) The present invention's single-tube multi-color mixed system makes the tubular article colorful and multi-color, greatly enhancing the market vitality and prospects, as shown in Figures 10-11.

The existing market screw extruders only produce single-color or double-color plastic tubes. Affected by the original cognition, awareness and environment, single-color or double-color tubes met most of the needs at that time. However, the main consumer force at that time has gradually aged. Now young people have become the new main consumer force. With the development of science and technology, life is becoming more and more colorful. Single-color and double-color tubes can no longer meet the needs of young people today. The market urgently needs more colorful products to attract young people to consume. The society is developing rapidly, but there has been no great improvement in the production of tubes. It still maintains the original single and old style. The market vitality and prospects are lacking and it can no longer keep up with market demand.

Based on the above reasons, the multi-color mixing system of the present invention adds more colors to the production of tubular products through a new color injection method. Its diversion system is equipped with 2 to 16 diversion channels, which can connect 2 to 16 sets of color injection barrels, mixers, etc. The color injection barrel, mixing barrel and flow guide system of the multi-color mixing system are all equipped with 2 to 16 material channels. Each material channel of the color injection barrel is equipped with a color injection port, which can inject 2 to 16 colors at the same time, so that the tubular product finally presents a multi-color tubular product with 2 to 16 different colors.

The present invention has the following beneficial effects: it solves the problem that the existing tubes in the market are only single-color

Or the deficiency of two colors, it enriches the types of tubular objects, makes the colors of tubular objects multi-color or multi-color mixed, improves the visual appreciation of tubular objects, meets the different pursuits of young people and the different needs of the market, and to a certain extent improves the attractiveness of related products using tubular objects, enhances market vitality and prospects, and meets market demand.

(5) The present invention sets anti-static annular cooling ring combination one and two, respectively, to cool the head mold one and two and the product extremely quickly, and efficiently shape them, which greatly reduces the cooling equipment, usage site and energy consumption, carbon emissions, and effectively saves cooling time. As shown in Figures 11-12, in the existing tubular production equipment or material particle production equipment, the tubular product and material particle product extruded from the discharge die are in a molten state and need to be quickly cooled and shaped, otherwise there will be shape deformation and adhesion, which affects normal production. In addition, rapid cooling has a great improvement on the mechanical properties of the tubular product, and packaging and sales also need to be cooled before they can be carried out, so cooling and cooling are required. Affected by the market and technical limitations, traditional cooling equipment is mostly equipped with a fan to cool down the conveyor, and the fan is used for cooling. However, the cooling effect of the fan is poor, the time is long, the cooling equipment is large, the floor area is large, and a lot of space resources are wasted. The equipment floor area, the number of personnel and the comprehensive energy consumption are large, and there are problems such as high energy consumption and high carbon emissions, which no longer meet the existing market industrial production needs.

Based on the above reasons, the anti-static annular cooling sleeve assembly device of the present invention is respectively arranged between the tubular object, the material particle head mold and the discharge mold and the traction system, and uses a high-pressure fan to generate high-speed flowing air to instantly and efficiently cool the produced tubular products and particle products. The device is equipped with a variable frequency automatic adjustment system to ensure that the wind pressure and flow are stable and controllable. The sleeve body adopts dual-channel dual-circuit circulating water cooling. The anti-static annular cooling sleeve assembly of the present invention quickly cools and shapes the molten tubular object and material particles extruded by the discharge mold, and has the following beneficial effects:

①: The cooling temperature can be set according to product requirements to ensure extremely fast cooling of the product, efficient shaping, and guaranteed product quality.

②: It solves the adhesion problem between products and between products and equipment, and also solves the deformation problem of products. Rapid cooling greatly improves the mechanical properties of tubular products and material particles.

③: The problem of uniform cooling can be achieved with only 1-5 meters of conveying equipment, which solves the low efficiency problems of traditional cooling devices that use 15-20 meters or even longer conveying devices with fans for cooling and cooling, long cooling time, uneven cooling, and large footprint. It not only greatly shortens the length of the cooling device and reduces the footprint of the equipment, but also reduces equipment costs, labor costs, production energy consumption and carbon emissions, improves production efficiency, and is more in line with the new market industrialization needs in terms of emission reduction, energy saving, and environmental protection.

(6) The present invention stacks the drying module and the screw extruder assembly module in multiple layers, which reduces the floor space and makes full use of the plant space, as shown in FIG. 7

Existing screw extruders are basically arranged in a plane. For example, when multiple screw extruders are needed to be used in coordination according to market development requirements, each screw extruder occupies a certain area. Multiple screw extruders are arranged in a front-to-back straight, L-shaped or T-shaped manner and occupy a lot of useless space when they are placed, resulting in a certain degree of waste of space. The overall area is large, and the height space is not fully utilized, resulting in a waste of space resources, and also requiring greater personnel arrangements and comprehensive energy consumption.

Based on the above reasons, the drying module and the screw extruder combination module of the present invention are configured as a multi-layer cloth The drying module is at the top, the first-stage screw extruder device is in the middle, and the second-stage and third-stage screw extruders are at the bottom. After being dried by the drying module, the material enters the first-stage screw extruder. After being extruded by the first-stage screw extruder, it enters the two second-stage and third-stage screw extruders at the bottom for synchronous production. The two screw extruders work synchronously to produce multiple-single-stage multi-color tubular objects and modified material particles simultaneously. The equipment is compactly placed up and down, making full use of the plant space, reducing the floor space of the equipment, reducing the number of operators to a certain extent, and reducing the comprehensive energy consumption, carbon emissions, personnel costs, etc.

The present invention stacks the drying module and the screw extruder combination module in multiple layers, which has the following beneficial effects: it solves the problems of large floor space, high labor costs, and high energy consumption of equipment for producing tubular objects and material particles; when producing tubular objects and particles at the same time, it reduces the floor space, reduces the corresponding equipment costs and labor costs, reduces production energy consumption, reduces carbon emissions, and improves production efficiency, which is more in line with the current market demand for industrialized production and more in line with national requirements in terms of emission reduction, energy saving, and environmental protection.

In summary, the present invention gives full play to the characteristics of each material and improves the physical strength and performance of the product. At the same time, the advanced preparation method improves the mechanical properties, heat resistance and physical stability of the product, which is conducive to the use and invention of more preparation methods; the present invention improves the production efficiency of tubular objects, while increasing the benefits, enriching the types of tubular objects, and allowing the colors of tubular objects to be mixed in multiple colors, which to a certain extent improves the attractiveness of related products using tubular objects, enhances market vitality and prospects, and meets the existing market demand.

The technology involved in the present invention is a typical multidisciplinary comprehensive technology, which requires professional knowledge of plastic processing, polymer molding machinery, physics and mechanical molds, etc. The present invention has both excellent comprehensive performance and green environmental protection characteristics, and has significant economic value and social significance.
