Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and more specifically, to a device for blending and extruding high-rigidity and high-toughness materials. Background Technology

[0002] High-rigidity and high-toughness materials refer to those that can maintain high hardness (rigidity) while absorbing a large amount of energy without fracturing (toughness) when subjected to external forces. These materials are widely used in aerospace, automotive manufacturing, sporting goods, building structures, and other fields where extremely high strength and durability are required. The production and processing of high-rigidity and high-toughness materials involves melting and mixing the raw materials before extrusion molding.

[0003] However, when processing high-rigidity and high-toughness materials, the existing blending extrusion equipment cannot ensure that the various raw materials enter the extruder accurately and uniformly according to the preset ratio because these materials usually contain a variety of raw materials with different properties (such as particle size, density, flowability, etc.). The large differences in flowability between different materials can easily cause some raw materials to flow into the extruder preferentially, resulting in unstable feed rate and affecting the performance consistency of the final product, making it difficult for the product to achieve the ideal high-rigidity and high-toughness characteristics.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a blending and extrusion device for high-rigidity and high-toughness materials to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An extrusion apparatus for blending high-rigidity and high-toughness materials includes: a frame; a protective housing disposed at the top of the frame; an extrusion cylinder disposed inside the protective housing; a feeding and mixing mechanism disposed on the outside of one end of the extrusion cylinder; a drive motor disposed on one end of the extrusion cylinder; a control box disposed on one side of the frame; and an exhaust treatment mechanism disposed on the outside of the extrusion cylinder.

[0008] Furthermore, in order to achieve close cooperation with the feeding and mixing mechanism, so that the feeding and mixing mechanism can accurately and stably feed the mixed raw materials into the extrusion cylinder, several uniformly arranged heating plates are provided on the outside of the extrusion cylinder, and a screw is provided inside the extrusion cylinder, with one end of the screw penetrating through the side wall of the extrusion cylinder and connected to the output shaft of the drive motor; a feed port that cooperates with the feeding and mixing mechanism is opened on the outside of the extrusion cylinder and inside the protective shell, and several exhaust holes are opened on the outside of the extrusion cylinder and inside the protective shell.

[0009] Furthermore, in order to achieve the mixing of raw materials, multiple storage chambers are set up so that each storage chamber can independently store different types or proportions of raw materials. This helps ensure that various raw materials enter the extruder accurately according to a preset ratio, and also overcomes the problem of preferential flow of some raw materials due to differences in the fluidity between different materials, ensuring uniform supply of raw materials and solving the problem of unstable feeding rate caused by differences in physical properties, thereby improving the performance consistency of the final product and giving the product better high rigidity and high toughness characteristics. The feeding and mixing mechanism includes a feeding cylinder set on the outside of one end of the extrusion cylinder, and the bottom end of the feeding cylinder is connected to the feed port. A storage tank is set at the top of the feeding cylinder, and several extension cylinders are set at the bottom of the outside of the storage tank. Several storage cavities are opened on the outside of the storage tank, and an installation cavity is opened in the middle of the storage tank. A drive rod is set inside the installation cavity. The top end of the drive rod passes through the top of the storage tank and is equipped with a feeding motor. A first bevel gear is set at the bottom end of the drive rod. Several second bevel gears are meshed on the outside of the top end of the first bevel gear. An auger is set on one side of the second bevel gear, passing through the bottom end of the storage cavity. A feeding pipe connected to the feeding cylinder is set at the bottom end of the extension cylinder, and several feed ports connected to the storage cavities are set at the top of the storage tank.

[0010] Furthermore, in order to allow the raw materials inside the storage chamber to flow to the auger and avoid the accumulation of raw materials inside the storage chamber, an installation groove that cooperates with the auger is opened in the middle of the bottom end of the storage chamber, and the height of both sides of the bottom end of the storage chamber gradually decreases along the direction closer to the middle of the bottom end of the storage chamber.

[0011] Furthermore, to ensure that the gas entrained in the molten material can smoothly enter the cavity inside the collar through the vent holes for effective degassing, and to prevent backflow by obstructing and interfering with the gas flow, thus maintaining a stable environment inside the extruder, the venting mechanism includes collars symmetrically arranged on the outside of the extruder, with both sides of the two sets of collars connected by bolts. One set of collars has a first connecting pipe at its top and a vacuum pump at its bottom. The other set of collars has a connection point at its bottom that connects to the first connecting pipe. The second connecting pipe is connected; the cross-section of the collar is a semi-circular structure, and the collar has a cavity inside. The bottom of the middle part of the cavity has a first through hole that communicates with the exhaust port, and the top of the middle part of the cavity has a second through hole that mates with the first connecting pipe. An anti-backflow plate is provided inside the cavity and between the first and second through holes. The anti-backflow plate has several evenly arranged disturbance channels inside. The disturbance channels are composed of two sets of inclined air intake channels, and a turbulence block is provided on one side of the air intake channel. The bottom of the turbulence block has an arc-shaped surface.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model has a reasonable and reliable structure. Through the uniform feeding of the feeding and mixing mechanism and the stable extrusion function of the extrusion cylinder, the continuity and stability of the production process are guaranteed, and the production efficiency is improved. The exhaust treatment mechanism can discharge the gas generated during the extrusion process in a timely and stable manner, which further improves the quality of the product.

[0014] 2. By setting up a feeding and mixing mechanism, the raw materials are mixed. The multiple storage chambers allow each chamber to independently store different types or proportions of raw materials. This helps ensure that various raw materials enter the extruder accurately according to the preset ratio. It also overcomes the problem of preferential flow of some raw materials due to differences in the flowability between different materials, ensuring a uniform supply of raw materials and solving the problem of unstable feed rate caused by differences in physical properties. This improves the performance consistency of the final product and gives the product better high rigidity and high toughness characteristics.

[0015] 3. By setting up an exhaust treatment mechanism, the gas entrained in the molten material can smoothly enter the cavity inside the collar through the exhaust hole, achieving effective degassing. Under the action of the anti-backflow plate, the gas is obstructed and interfered with, making it difficult for it to pass smoothly, thus ensuring the stability of the environment inside the extrusion barrel.

Detailed Implementation

[0029] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0030] According to an embodiment of the present invention, an apparatus for blending and extruding high-rigidity and high-toughness materials is provided.

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-10 As shown, the extrusion apparatus for blending high-rigidity and high-toughness materials according to an embodiment of the present invention includes: a frame 1; a protective housing 2 disposed at the top of the frame 1; an extrusion cylinder 3 disposed inside the protective housing 2; a feeding and mixing mechanism 4 disposed on the outer side of one end of the extrusion cylinder 3; a drive motor 5 disposed on one end of the extrusion cylinder 3; a control box 6 disposed on one side of the frame 1; and an exhaust treatment mechanism 7 disposed on the outer side of the extrusion cylinder 3.

[0032] It should be further noted that the control box 6 contains a PLC control system, and the feeding and mixing mechanism 4, drive motor 5, and exhaust treatment mechanism 7 are all electrically connected to the control box 6. The PLC control system has high-precision data processing and control capabilities, and can accurately adjust parameters such as the feeding speed of the feeding and mixing mechanism 4, the speed of the drive motor 5, and the suction intensity of the exhaust treatment mechanism 7 according to the characteristics of different materials and production requirements. Furthermore, the control box 6 is equipped with an intuitive human-machine interface, such as a touch screen or operation panel. Operators can use this interface to view the real-time operating status of the device, the working parameters of each component, and production data. Simultaneously, various operations can be performed on the interface, such as starting and stopping the device, adjusting operating parameters, and setting production formulas.

[0033] With the help of the above-mentioned technical solution of this utility model, the structure of this utility model is reasonable and reliable. Through the uniform feeding of the feeding and mixing mechanism 4 and the stable extrusion function of the extrusion cylinder 3, the continuity and stability of the production process are guaranteed, and the production efficiency is improved. The exhaust treatment mechanism 7 can timely and stably discharge the gas generated during the extrusion process, further improving the quality of the product.

[0034] In one embodiment, for the extrusion cylinder 3, a plurality of uniformly arranged heating plates 301 are provided on the outer side of the extrusion cylinder 3, and a screw 302 is provided inside the extrusion cylinder 3, with one end of the screw 302 penetrating through the side wall of the extrusion cylinder 3 and connected to the output shaft of the drive motor 5; an inlet 303 that cooperates with the feeding and mixing mechanism 4 is opened on the outer side of one end of the extrusion cylinder 3, and a plurality of exhaust holes 304 are opened on the outer side of the extrusion cylinder 3 and inside the protective housing 2, thereby achieving a close cooperation with the feeding and mixing mechanism 4, so that the feeding and mixing mechanism 4 can accurately and stably feed the mixed raw materials into the extrusion cylinder 3.

[0035] It should be noted that the heating element 301 is electrically connected to the control box 6 and is precisely controlled by the PLC control system inside the control box 6. The operator can set the desired extrusion temperature on the human-machine interface of the control box 6. The PLC control system will monitor the actual temperature inside the extrusion cylinder 3 in real time according to the set temperature value and control the temperature by adjusting the heating power of the heating element 301. To achieve precise temperature control, a temperature sensor is usually installed inside the extrusion cylinder 3 to monitor the temperature inside the extrusion cylinder 3 in real time and feed the temperature signal back to the control box 6. This is existing technology and will not be elaborated upon further here.

[0036] The working principle of the extrusion cylinder 3 is as follows: by starting the drive motor 5, its output shaft drives the screw 302 inside the extrusion cylinder 3 to rotate. The raw material entering the extrusion cylinder 3 is pushed forward along the extrusion cylinder 3 by the screw thread of the screw 302. The rotation of the screw 302 generates shearing and stirring effects on the raw material, further promoting the mixing of different raw materials. At the same time, the heating plate on the outside of the extrusion cylinder 3 heats the inside of the extrusion cylinder 3. As the raw material is conveyed in the extrusion cylinder 3, the temperature gradually rises. The raw material is plasticized at a suitable temperature, changing from a solid state to a molten state with a certain fluidity.

[0037] In one embodiment, the feeding and mixing mechanism 4 includes a feeding cylinder 401 disposed on the outer side of one end of the extrusion cylinder 3, with the bottom end of the feeding cylinder 401 communicating with the inlet 303. A storage tank 402 is disposed at the top of the feeding cylinder 401, and several extension cylinders 403 are disposed at the bottom outer side of the storage tank 402. Several storage cavities 404 are opened on the outer side of the storage tank 402, and an installation cavity 405 is opened in the middle of the storage tank 402. A drive rod 406 is disposed inside the installation cavity 405, with the top end of the drive rod 406 penetrating through the top end of the storage tank 402 and housing a feeding motor 407. A first bevel gear 408 is disposed at the bottom end of the drive rod 406. Several second bevel gears 409 are meshed on the outer side of the top end, and an auger 410 is provided on one side of the second bevel gears 409, penetrating the bottom end of the storage cavity 404; a discharge pipe 411 connected to the discharge cylinder 401 is provided at the bottom end of the extension cylinder 403; an installation groove 4041 that cooperates with the auger 410 is opened in the middle of the bottom end of the storage cavity 404, and the height of both sides of the bottom end of the storage cavity 404 gradually decreases along the direction close to the middle of the bottom end of the storage cavity 404; several feed inlets 412 connected to the storage cavity 404 are provided at the top of the storage hopper 402, thereby realizing the mixing of raw materials. The setting of multiple storage cavities 404 allows each storage cavity 404 to independently store different types or proportions of raw materials. This helps ensure that various raw materials enter the extrusion cylinder accurately according to the preset ratio. It can also overcome the problem of some raw materials flowing in preferentially due to the difference in flowability between different materials, ensuring a uniform supply of raw materials and solving the problem of unstable feed rate caused by differences in physical properties. This improves the performance consistency of the final product and gives the product better high rigidity and high toughness characteristics.

[0038] In addition, in specific applications, the bottom and top ends of the drive rod 406 are connected to the storage tank 402 by bearings, one end of the auger 410 is connected to the inner wall of the storage cavity 404 by bearings, and the other end of the auger 410 is connected to the inner wall of the extension cylinder 403 by bearings.

[0039] Since different raw materials require different qualities, the pitch of each auger 410 is different. For raw materials requiring a larger conveying capacity, the pitch of the corresponding auger 410 will be set relatively large. A larger pitch allows the raw material to obtain a greater axial propulsion force per unit length, thereby accelerating the conveying speed and increasing the conveying capacity per unit time. For example, in the production of high-rigidity and high-toughness materials, if a certain main material needs to be supplied in large quantities, the pitch of the auger 410 corresponding to the storage chamber 404 containing that main material will be designed to be larger to meet the feeding requirements of the main material. Conversely, for additives that require precise control of the addition amount and are added in relatively small quantities, the pitch of the corresponding auger 410 will be smaller to slow down the conveying speed and ensure that the additive can enter the feed cylinder 401 slowly and stably according to a precise ratio. Moreover, the diameter of each auger 410 is also different, and the diameter of the auger can be adjusted according to specific needs. Generally speaking, augers with larger diameters are suitable for high-flow material conveying, while augers with smaller diameters are more suitable for low-flow, fine-control scenarios. By precisely controlling the feed rate of each raw material, we ensure that all components are mixed in the correct proportions (the above are all existing technologies and will not be elaborated on here).

[0040] The working principle of the feeding and mixing mechanism 4 is as follows: The operator pours high-rigidity and high-toughness materials with different properties into the storage chambers 404 of the storage tank 402 in the feeding and mixing mechanism 4, and then starts the feeding motor 407. The output shaft of the feeding motor 407 drives the drive rod 406 to rotate, which in turn causes the first bevel gear 408 to rotate. Under the meshing of the first bevel gear 408 and multiple second bevel gears 409, the first bevel gear 408 drives each second bevel gear 409 to rotate, thereby driving the auger 410 to rotate in the mounting groove 4041 at the bottom of the storage chamber 404. Through the rotation of the auger 410, the raw materials in the storage chamber 404 are transported to the discharge cylinder 401, and then enter the extrusion cylinder 3 through the discharge pipe 411, so as to achieve uniform feeding and preliminary mixing of different raw materials.

[0041] In one embodiment, the exhaust treatment mechanism 7 includes symmetrically arranged collars 701 on the outside of the extrusion cylinder 3, with both sides of the two sets of collars 701 connected by bolts 702; one set of collars 701 has a first connecting pipe 703 at its top end and a vacuum pump 704 at its bottom end; the other set of collars 701 has a second connecting pipe 705 at its bottom end connected to the first connecting pipe 703; the collars 701 have a semi-annular cross-section, and a cavity 7011 is formed inside the collars 701. A first through hole 7012 communicating with the exhaust port 304 is formed at the bottom center of the cavity 7011, and a through hole 7012 communicating with the exhaust port 304 is formed at the top center of the cavity 7011. A second through hole 7013 that mates with the first through hole 7012 is provided inside the cavity 7011 and between the first through hole 7012 and the second through hole 7013. A backflow prevention plate 7014 is provided inside the anti-backflow prevention plate 7014. Several uniformly arranged disturbance channels are provided inside the anti-backflow prevention plate 7014. The disturbance channels are composed of two sets of inclined air inlet channels 70141. A disturbance block 70142 is provided on one side of the air inlet channel 70141. An arc-shaped surface 70143 is provided at the bottom end of the disturbance block 70142. This allows the gas entrained in the molten material to pass smoothly through the exhaust hole into the cavity inside the collar, achieving effective degassing. Under the action of the anti-backflow prevention plate 7014, the gas is obstructed and interfered with, making it difficult for it to pass smoothly, thereby ensuring the stability of the internal environment of the extrusion cylinder 3.

[0042] In addition, it should be noted that after the gas is extracted by the vacuum pump 704, the extracted gas is processed by a pre-set gas collection device or processing device. This is existing technology and will not be elaborated on here.

[0043] The working principle of the exhaust treatment mechanism 7 is as follows: During the plasticizing and conveying of raw materials, gas will be generated. The vacuum pump 704 is started, and the gas in the collar 701 is extracted through the first connecting pipe 703 and the second connecting pipe 705, so that a negative pressure is formed inside the collar 701. This promotes the gas generated to enter the collar 701 of the exhaust treatment mechanism 7 through the exhaust hole 304 on the outside of the extrusion cylinder 3. The gas enters the cavity 7011 through the first through hole 7012. When the gas passes through the anti-backflow plate 7014 in the cavity 7011, the backflow gas can be blocked by the cooperation of the baffle block 70142 and the arc surface 70143, thus preventing the gas from flowing back.

[0044] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0045] In practical applications, the operator first pours high-rigidity and high-toughness materials with different properties into the feeding and mixing mechanism 4. The feeding and mixing mechanism 4 evenly conveys the different materials to the extrusion cylinder 3. Then, the drive motor 5 is started to realize the conveying, mixing, heating and plasticizing of the materials. During the material plasticizing and conveying process, the generated gas is discharged through the exhaust treatment mechanism 7. After being fully mixed, plasticized and vented, the material is extruded from the other end of the extrusion cylinder 3 to form a product with a certain shape and size. During this process, the operator sets and adjusts the operating parameters of the entire device through the control box 6, such as heating temperature and feeding speed, to ensure the stable operation of the device and the stability of product quality.

[0046] In summary, with the help of the above-mentioned technical solution of this utility model, the structure of this utility model is reasonable and reliable. Through the uniform feeding of the feeding and mixing mechanism 4 and the stable extrusion function of the extrusion cylinder 3, the continuity and stability of the production process are ensured, and production efficiency is improved. The exhaust treatment mechanism 7 can timely and stably discharge the gas generated during the extrusion process, further improving product quality. By setting up the feeding and mixing mechanism 4, the mixing of raw materials is realized. The setting of multiple storage chambers 404 allows each storage chamber 404 to independently store different types or proportions of raw materials. This helps ensure that various raw materials enter the extruder accurately according to the preset ratio, and can also overcome the problem of preferential flow of some raw materials due to differences in the fluidity between different materials, ensuring uniform supply of raw materials and solving the problem of unstable feeding rate caused by differences in physical properties, thereby improving the performance consistency of the final product and giving the product better high rigidity and high toughness characteristics. By setting up the exhaust treatment mechanism 7, the gas entrained in the molten material can smoothly enter the cavity 7011 inside the collar 701 through the exhaust hole, achieving effective degassing. Under the action of the anti-backflow plate 7014, the gas is obstructed and interfered with, making it difficult for it to pass smoothly, thereby ensuring the stability of the internal environment of the extrusion cylinder 3.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
