Description

Technical Field

[0001] This utility model relates to the technical field of extruded polystyrene board production equipment, specifically to an efficient mixing device for extruded polystyrene board raw materials. Background Technology

[0002] Extruded polystyrene (XPS) boards are widely used in the construction industry due to their high compressive strength, lightweight, non-absorbent, airtight, wear-resistant, and non-degradable properties. They are made primarily from polystyrene resin, supplemented with various additives, which are heated, mixed, and then extruded after a catalyst is injected. During the production process, the uniformity of the raw material mixing plays a decisive role in product quality. Uneven mixing can lead to unstable performance of the XPS board, such as insufficient compressive strength and reduced thermal insulation properties.

[0003] Chinese Patent Announcement No. CN220242051U discloses a mixing device for extruded raw materials, relating to the technical field of cable production equipment. The device includes a mixing tank and a hopper. A first stirring rod is installed on the inner wall of the mixing tank. The mixing tank is rotatably connected to a mounting base. The top of the mounting base is connected to a fixed plate. A mounting plate is rotatably installed at the opening of the mixing tank. A support is provided between the mounting plate and the fixed plate. An auger is horizontally installed on the support, located below the hopper. A drive assembly is fixedly installed along the axis of the mounting plate. This invention utilizes an auger and pressure sensor to control precise material feeding. The rotation of the mixing tank ensures the raw materials are evenly dispersed within the tank upon input. The second stirring rod rotates and rises / falls, enhancing the mixing effect. Spiral blades lift the raw materials upwards, resulting in more uniform mixing. The device also clears blockages in the discharge pipe, improving discharge efficiency and preventing clogging. This precise material dispensing and uniform mixing shortens mixing time, enhances mixing effectiveness, and improves work efficiency.

[0004] In the prior art, when the raw materials being used in an extrusion raw material mixing device are clumping, direct stirring may result in uneven mixing, affecting product quality, increasing stirring resistance, reducing stirring efficiency, and even damaging the stirring components. Therefore, we have made improvements to this issue and proposed an efficient mixing device for extruded polystyrene board raw materials. Utility Model Content

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0030] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. 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 communication of two components or the interaction between two components.

[0034] Example 1: Please refer to the appendix of the instruction manual. Figure 1-3 A high-efficiency mixing device for extruded polystyrene board raw materials includes a housing 1. Inside the housing 1 are two dispersing and stirring rods 11, both ends of which are inserted into and rotatably connected to the housing 1. A first gear 12 is fixedly installed on one side of each of the two dispersing and stirring rods 11, and the two first gears 12 mesh and are rotatably connected to the housing 1. A second servo motor 13 is fixedly installed inside the housing 1, and its output end is fixedly connected to one of the first gears 12. Multiple serrated impellers are fixedly installed on the outer sides of each of the two dispersing and stirring rods 11. A stirring structure is provided inside the housing 1, and a filter plate 14 is rotatably connected to the inside of the housing 1 via a rotating shaft.

[0035] In this embodiment of the utility model, the output end of the second servo motor 13 drives the first gear 12 connected to it to rotate. Since the two first gears 12 mesh with each other, they will drive the other first gear 12 to rotate in the opposite direction, thereby causing the two dispersing and stirring rods 11 to rotate in the opposite direction. During the rotation, the serrated impeller on the outside of the dispersing and stirring rod 11 performs preliminary dispersing treatment on the raw materials to prevent the raw materials from clumping and to provide a good foundation for subsequent stirring.

[0036] In this embodiment of the invention, this preliminary dispersing process effectively avoids the caking of raw materials from hindering the subsequent mixing process, allowing the raw materials to be mixed more quickly and thoroughly during subsequent mixing, greatly improving the efficiency of the entire mixing process, reducing mixing time, and increasing production efficiency.

[0037] Example 2: Please refer to the appendix of the instruction manual. Figure 1-5 In a preferred embodiment of this utility model, a feed inlet is provided on the box body 1.

A through groove is provided on the box body 1 to cooperate with the two feed pipes.

[0038] The stirring structure includes a first rotating rod 2, a second rotating rod 3, and a third rotating rod 4. Both ends of the first rotating rod 2, the second rotating rod 3, and the third rotating rod 4 are inserted into the interior of the housing 1 and rotatably connected thereto. Multiple propeller-type stirring blades are fixedly installed on the outer side of the first rotating rod 2. Multiple arc-shaped stirring blades 5 are fixedly installed on the outer side of the second rotating rod 3 and the third rotating rod 4. A first servo motor 10 is fixedly installed inside the housing 1. A first sprocket 6 is fixedly installed at the output end of the first servo motor 10. The first sprocket 6 is fixedly installed on the outer side of the first rotating rod 2. A second sprocket 28 is fixedly installed on the outer side of the second rotating rod 3. Both the first sprocket 6 and the second sprocket 28 are rotatably connected to the housing 1. A chain 8 is driven to the outer side of the first sprocket 6 and the second sprocket 28. The arc-shaped stirring blades 5 adopt an asymmetrical hyperboloid shape.

[0039] A second gear 7 is fixedly installed on one side of the second rotating rod 3, and a third gear 9 is fixedly installed on one side of the third rotating rod 4. Both the second gear 7 and the third gear 9 are rotatably connected to the housing 1. The second gear 7 and the third gear 9 mesh. The second gear 7 and the second sprocket 28 have the same diameter. The diameters of the first sprocket 6, the second gear 7 and the third gear 9 increase sequentially.

[0040] Scrapers 27 are provided on both sides of the third rotating rod 4. Both scrapers 27 are fixedly connected to the arc-shaped stirring blade 5, and both scrapers 27 are slidably connected to the box body 1.

[0041] A third servo motor 16 is fixedly installed inside the housing 1. A fixed rod 17 is fixedly installed at the output end of the third servo motor 16. Two cams 18 are fixedly installed on the outside of the fixed rod 17. The fixed rod 17 and the two cams 18 are rotatably connected to the housing 1. A bracket 15 is fixedly installed on the top of one side of the filter plate 14. The two cams 18 are slidably connected to the bracket 15.

[0042] The bracket 15 is inserted into the interior of the housing 1 and slidably connected thereto. Multiple return springs 19 are fixedly installed at the bottom of the bracket 15. The ends of the multiple return springs 19 away from the bracket 15 are fixedly connected to the housing 1. An arc-shaped plate 20 is fixedly installed at the top of the filter plate 14. The arc-shaped plate 20 is inserted into the interior of the housing 1 and slidably connected thereto.

[0043] A controller 26 is embedded on one side of the housing 1. The controller 26 is electrically connected to the first servo motor 10, the second servo motor 13 and the third servo motor 16. A transparent window is provided on the housing 1. A door is provided on one side of the housing 1. The door is inserted into the interior of the housing 1 and is slidably connected to it. Multiple fixing bolts are provided on the side of the door away from the housing 1. All the fixing bolts are inserted into the interior of the housing 1 and are threadedly connected to it. All the fixing bolts pass through the door and are threadedly connected to it.

[0044] In this embodiment of the invention, the opening and closing of the feed inlet is achieved by sliding the baffle 21, and the compression spring can automatically reset the baffle 21 when it is not subjected to external force, thus ensuring the controllability of the feed.

[0045] The first sprocket 6 rotates under the drive of the first servo motor 10, and transmits power to the second sprocket 28 through the chain 8, thereby causing the second rotating rod 3 to rotate. The second gear 7 on the second rotating rod 3 meshes with the third gear 9 on the third rotating rod 4, driving the third rotating rod 4 to rotate. Because the diameters of the first sprocket 6, the second gear 7, and the third gear 9 increase sequentially, according to the gear transmission principle, the three rotating rods will rotate at different speeds. When the propeller-type stirring blades on the first rotating rod 2 rotate, they will generate axial thrust, pushing the raw materials to move axially. The arc-shaped stirring blades 5 with asymmetrical hyperboloid shape on the second rotating rod 3 and the third rotating rod 4 can not only generate strong tumbling and convection in the radial direction of the raw materials during rotation, but also use the different stirring forces brought by the asymmetrical shape to make the raw materials subject to forces in different directions, achieving all-round and multi-angle movement. At the same time, the scraper 27 on the third rotating rod 4 will slide close to the inner wall of the box 1, scraping off the material adhering to the wall of the box 1, so that it can re-participate in the mixing.

[0046] The third servo motor 16 drives the fixed rod 17 and the two cams 18 to rotate. As the cams 18 rotate, their protrusions push the support 15 on one side of the filter plate 14 upward, causing the filter plate 14 to rotate around the axis at a certain angle. At this time, the return spring 19 is stretched. When the protrusion of the cam 18 moves away from the support 15, the filter plate 14 will quickly return to its original position under the elastic force of the return spring 19. This process is repeated, causing the filter plate 14 to vibrate at a high frequency. The dispersed material falls onto the filter plate 14. Under the action of vibration, the material that meets the particle size requirements will fall through the sieve holes of the filter plate 14, while the unqualified large particles will be intercepted on the filter plate 14, thus achieving effective filtration and separation of the material.

[0047] A controller 26 is embedded on one side of the housing 1, which is electrically connected to the first servo motor 10, the second servo motor 13 and the third servo motor 16 to control each motor. A transparent window is provided on the housing 1 to facilitate observation of the internal situation. A door is provided on one side, which is connected to the housing 1 by fixing bolts to facilitate equipment maintenance and cleaning.

[0048] Example 3: Please refer to the appendix of the instruction manual. Figure 2 , Figure 4 and Figure 6 In a preferred embodiment of this utility model, multiple temperature sensors are embedded in one side of the inner wall of the housing 1. Heating tubes are fixedly installed inside the housing 1 on both sides corresponding to the second rotating rod 3. A main pipe is provided on one side of the housing 1, and the main pipe is inserted into the housing 1 and fixedly connected to it. A first pipe, a second pipe, and a third pipe are fixedly installed on one side of the main pipe. The first pipe, the second pipe, and the third pipe are all fixedly connected to the housing 1. The main pipe communicates with the first pipe, the second pipe, and the third pipe. The first pipe and the second pipe are both fixedly connected to the third pipe, and the third pipe has a through groove that mates with the first pipe and the second pipe. The main pipe and the third pipe pass through one side of the housing 1 and are fixedly connected thereto. Both the main pipe and the third pipe are connected to an external circulating coolant device. A discharge pipe 25 is provided at the bottom of the housing 1. A through-hole plate is fixedly installed inside the discharge pipe 25. A flange 24 is fixedly installed on the outside of the discharge pipe 25. The flange 24 is inserted into the inside of the housing 1 and is slidably connected thereto. Multiple fixing bolts are provided at the bottom of the flange 24. All of the multiple fixing bolts are inserted into the inside of the housing 1 and are threadedly connected thereto. All of the multiple fixing bolts pass through the flange 24 and are threadedly connected thereto. A valve is provided on the outside of the discharge pipe 25. The controller 26 is electrically connected to the temperature sensor, the valve, the heating pipe and the external circulating coolant device.

[0049] In this embodiment of the invention, a temperature sensor on the inner wall of the housing 1 monitors the internal temperature in real time and feeds the temperature data back to the controller 26. When the temperature sensor detects that the temperature inside the housing 1 is lower than the set value, the controller 26 issues a command to start the heating tube. The heating tube begins to heat up and heats the raw materials inside the housing 1, causing the temperature to gradually rise. When the temperature exceeds the set value, the controller 26 controls the external circulating coolant device to start working. The coolant circulates inside the housing 1 through the main pipe, the first pipe, the second pipe, and the third pipe, carrying away excess heat and lowering the temperature. Through this dynamic adjustment process of heating and cooling, precise control of the internal temperature of the housing 1 is achieved.

[0050] In this embodiment of the invention, different extruded polystyrene board raw materials have different temperature requirements during the mixing process. Precise temperature control can ensure the stability of the physical and chemical properties of the raw materials, avoid changes in the performance of the raw materials due to unsuitable temperature, and ensure the reaction conditions of the raw materials during the mixing process, thereby improving product quality and production efficiency, and making the various performance indicators of the produced extruded polystyrene board meet the standard requirements.

[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
