Description
Technical Field
The invention relates to a mechanical device for synchronously producing a plurality of single multicolor tubular objects and modified material particles by adopting a plurality of feed inlets, belongs to the field of production of tubular objects and particles by adopting an extruder, and in particular relates to a mechanical device for synchronously producing a plurality of single multicolor tubular objects and modified material particles by adopting a plurality of feed inlets.
Background
With the improvement of incomes which can be controlled by people, the life style of people is changing, the consumption scale is further enlarged, the use amount of disposable straws is larger and larger, the market scale of industry is in a trend of increasing, and related matched production equipment does not keep pace with the development of the existing market. According to data display and research, the existing production equipment for straws and tubes in the market currently has the following problems:
(1) The existing production equipment only has one feed inlet, so that the stability of the product cannot be ensured, and the new large-scale preparation cannot be met
The disposable straws in the existing market mainly comprise degradable straws and edible straws, various materials are needed for producing the degradable straws and the edible straws, different materials have different physical and chemical properties, the change and the produced effect at different stages in the extruder also have obvious differences, all materials basically enter the extruder at the same time in the existing production mode of the extruder equipment in the market, and materials with different characteristics enter the extruder at the same time, so that a plurality of uncontrollable factors can appear. The materials needing low-temperature modification and the high-temperature resistant materials are mixed together in a low-temperature area, the high-temperature resistant materials and the low-temperature resistant modified materials are not reacted or changed, but the space and the heat of the low-temperature resistant modified materials are occupied, so that the modification time of the low-temperature resistant modified materials is relatively reduced, the heating area is relatively reduced, the modification process of the low-temperature resistant modified materials is blocked to a certain extent, the low-temperature resistant modified materials cannot be completely modified, and cannot be completely resistant to high temperature, so that the low-temperature resistant modified materials are easy to carbonize after entering the high-temperature area, and finally more defective products are easy to appear; meanwhile, the effect of compatible materials is greatly reduced, the quality instability of products in normal production is caused, the problems of uneven strength, poor heat resistance and the like of tubular products are caused, the stability of the products cannot be ensured, and a new preparation method and scientific research test cannot be met, so that the preparation mode for producing degradable plastic products with stable quality and large scale production is not always available in the current market. Therefore, a special treatment mode is needed to optimize, so that the production raw materials fully play the role in the extruder, and the characteristics of various materials are better kept.
(2) The existing production equipment can only produce a single product, cannot fully exert the performance of the production equipment, has low production efficiency and causes energy waste
The existing disposable straw and tubular object production device has the advantages that the production chain is complete, industrial production is realized, but the existing extruder is basically single production, the straw and tubular object production device is not greatly improved all the time due to various reasons such as economic benefit conflict and difficult technical breakthrough, and finally, the production efficiency is not obviously improved, and the production device cannot be fully utilized
The standby performance causes energy waste.
(3) The existing production equipment can only produce single color or double colors and can not produce multicolor or mixed color
The existing disposable straws and tubes are single-color or double-color, and the disposable straws and tubes with more than two colors have not been found in the market and have not been reported. The existing market is rapidly developed, the production of disposable straws and tubes is not greatly improved, the original production style is still maintained, but the existing production style is quite single, people have visual fatigue, the propaganda attractiveness of related products using the disposable straws and tubes is reduced to a certain extent, the market vitality and prospect are deficient, the existing market demands are not kept up, the consumer view of people is always changed, the market of the disposable straws and tubes also needs to be further improved and adjusted, and the market needs the disposable straws and tubes with more styles and colors.
(4) The existing tubular product production equipment or material particle production equipment can only singly produce tubular products or singly produce material particles, and two sets of production equipment are needed for producing the tubular products and the material particles, so that not only are manpower, financial resources and energy resources wasted, but also the space is occupied
In the preparation method for producing the tubular objects, the raw materials for producing the tubular objects and the straw basically need material particles, and the tubular objects and the straw can also serve as the material particles to a certain extent, so that the tubular objects and the material particles complement each other, mutually symbiotic and mutually used. In the case of only the production equipment of the tubular objects, if the production equipment is needed, new production equipment is needed, in the case of only the production equipment of the material particles, if the production equipment is needed, new production equipment is also needed, and the new production equipment is added, more using sites, energy consumption, labor cost and the like are increased, so that certain investment repetition and cost superposition are caused, and the problems of high energy consumption, high carbon emission and the like are also caused.
(5) The existing tubular product production equipment or material particle production equipment has the defects that the temperature of a tubular product extruded from a discharge die is high, the tubular product is in a molten state, quick cooling and shaping are needed, otherwise, the phenomenon of shape deformation and adhesion can occur, normal production can be influenced, in addition, the mechanical property of a tubular product is greatly improved by quick cooling, and the packaging and selling can be carried out after cooling is needed, so that the cooling is needed. The traditional cooling equipment is mostly cooled and cooled by adding fans to a conveyor due to market influence and technical limitation and utilizes the fans to cool. But the cooling time of the fan is longer, the cooling effect is worse, the requirement of conveying equipment is longer, the occupied area is larger, the waste of large space resources is caused, the requirements on the occupied area of equipment, the number of personnel and comprehensive energy consumption are larger, the problems of high energy consumption, high carbon emission and the like are also caused, and the industrial production requirements of the existing market are not met.
The biodegradable material is a feasible and effective way for solving the problems of environmental pollution caused by plastic wastes and relieving the shortage of petroleum resources. The biodegradable material is mainly prepared by synthesizing biodegradable polymers such as thermoplastic starch plastics, polylactic acid and the like through an extruder. With the issuance of new edition of plastic limiting command, china is expected to become the global maximum biodegradable plastic consumer market in recent years. And the production equipment is behind, so that the preparation method of the degradation particles is limited to a certain extent. All materials enter the extruder at the same time in the existing production mode of extruder equipment in the market basically, but materials with different characteristics enter the extruder at the same time, so that a plurality of uncontrollable factors can appear, the phenomenon is particularly obvious when material particles are produced, the low-temperature materials and the high-temperature materials are mixed and do not react and change in a low-temperature region at the same time, but occupy the space and heat of the low-temperature materials, so that the modification time of the low-temperature materials is relatively reduced, the heated area is relatively reduced, the low-temperature materials are not completely modified, unstable quality easily appears, the particle strength is uneven, and the physical property is caused
The problems of unstable performance and the like are solved, and therefore, the material characteristics are required to be fully exerted and maintained as in the production device of the tubular product.
The advantages and disadvantages of the existing production equipment are shown in table 1:
in summary, the existing production equipment only has one feed inlet, materials can only enter the extruder once, the characteristics of different materials cannot be fully utilized, and the problems of uneven product strength, unstable physical properties and the like are easy to occur; during production, only a single tube can be produced, the production capacity of an extruder is limited, and single production can only produce single-color or double-color tubes, and multi-color or mixed-color tubes cannot be produced, so that the production style is single, and the market propaganda attractiveness is lacking.
In the preparation method for producing the tubular objects, the production raw materials basically need material particles, the tubular objects can also serve as the material particles to a certain extent, so that the tubular objects and the material particles complement each other and mutually form symbiosis, a plurality of conditions of simultaneously producing the tubular objects and the material particles are required in the existing market, and the existing equipment can only singly produce the tubular objects or singly produce the material particles and cannot meet the existing market demands.
