Description

Technical Field

[0001] The invention relates to the technical field of foaming and filling, and in particular discloses a production line for foaming and filling of aluminum profiles through extrusion molding. Background Art

[0002] In the aluminum profile processing industry, in order to improve the thermal insulation and sound insulation properties of the product, it is often necessary to fill the aluminum profile with foaming materials. The traditional foaming material preparation and mixing process often relies on manual operation or simple mechanical equipment, resulting in insufficient mixing uniformity of the foaming material, affecting the subsequent foaming effect. In the process from preparation to filling of the foaming material, due to the influence of factors such as the conveying pipeline and temperature control, the foaming material is prone to deterioration, thus affecting its filling effect and the performance of the final product. Summary of the invention

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a production line for aluminum profile extrusion molding, foaming and filling.

[0004] To achieve the above-mentioned purpose, the present invention provides an aluminum profile extrusion molding foaming filling production line, comprising a foaming material storage unit, a mixing unit and a filling unit, wherein the foaming material storage unit is connected to the mixing unit via a first connecting pipe body, and the mixing unit is connected to the filling unit via a second connecting pipe body, the foaming material in the foaming material storage unit is transported to the mixing unit via the first connecting pipe body, the mixing unit transports the mixed foaming material to the filling unit via the second connecting pipe body, and the filling unit performs a foaming material filling operation on the external aluminum profile;

[0005] The mixing unit includes a first barrel body, a stirring unit installed on the first barrel body, a vacuum unit, and a heating unit. The stirring unit includes a first driving member, a rotating shaft connected to the output end of the first driving member, and a plurality of spiral blades spirally wound on the outer wall of the rotating shaft. The spacing between the spiral blades increases continuously from the bottom of the first barrel body to the top of the first barrel body. The first driving member drives the rotating shaft to rotate to drive the spiral blades to rotate and stir the foaming material evenly. The vacuum unit vacuums the foaming material stirred by the stirring unit to remove bubbles generated during the foaming process of the foamed foaming material. The heating unit is arranged on the inner side of the first barrel body to adjust the temperature of the first barrel body to maintain the reaction temperature of the foaming material.

[0006] By integrating the foam material storage, efficient mixing and precise filling units, the uniform preparation and stable delivery of the foam material are achieved. In specific implementation, the mixing unit uses variable pitch spiral blades to enhance the stirring effect, combined with vacuum degassing and temperature control heating to ensure high-quality mixing of the foam material; then, through the pipe connection, the mixed material is accurately delivered to the filling unit to complete the efficient filling of the aluminum profile.

[0007] The heating unit comprises a heating plate installed on the side wall of the first barrel body, and a heat insulation layer is provided on the side of the heating plate facing the first barrel body side wall; the first barrel body side wall is provided with an avoidance groove for accommodating the heating plate, and the depth of the avoidance groove is the same as the thickness of the heating plate.

[0008] By installing a heating plate with an insulation layer on the side wall of the first barrel and cleverly setting an avoidance groove with the same thickness as the heating plate, the reaction temperature of the foaming material can be precisely controlled, and heat loss can be effectively prevented, thereby improving energy efficiency. In specific implementation, the heating plate fits tightly in the avoidance groove, and the heat it emits acts evenly on the foaming material in the first barrel, promoting the full reaction of the material; at the same time, the insulation layer effectively blocks the transfer of heat to the outer wall of the first barrel, reducing energy loss, making the entire heating process more efficient and energy-saving. This design not only improves the quality stability of the foaming material, but also further reduces production costs.

[0009] There are two groups of foaming material storage units, one group of foaming material storage units is used to store foaming raw materials, and the other group of foaming material storage units is used to store adhesives; the foaming material storage units include a second barrel body, a conveying pipe body installed on the second barrel body, the first connecting pipe body is connected to the mixing unit via the conveying pipe body, and the conveying pipe body is provided with a control valve for controlling the delivery of foaming materials.

[0010] By setting up two groups of foam material storage units, which are used to store foam raw materials and adhesives respectively, classified storage and flexible allocation of materials are achieved. In specific implementation, each group of storage units includes a second barrel and a conveying pipe body. The conveying pipe body is equipped with a control valve, which can accurately control the outflow of foaming materials to ensure that the materials are delivered to the mixing unit on demand and stably. This design not only improves the convenience and accuracy of material management, but also effectively avoids cross-contamination between different materials, laying a solid foundation for subsequent mixing and filling operations. At the same time, the precise regulation of the control valve also ensures the uniformity and stability of the foaming material during the mixing process, further improving the quality and performance of the final product.

[0011] The filling unit includes a frame, a third barrel body arranged on the frame and a filling assembly. The third barrel body is provided with a feed port, one end of the second connecting tube body is connected to the mixing unit, and the other end of the second connecting tube body away from the mixing unit is connected to the feed port of the third barrel body. The foamed foaming material flows into the third barrel body through the second connecting tube body and waits for the filling assembly to perform a filling operation.

[0012] The third barrel on the frame is used as a transfer station to receive the foaming material from the mixing unit, and the filling operation is completed with the help of the filling component. In specific implementation, the second connecting pipe body stably transports the mixed foaming material from the mixing unit to the feeding port of the third barrel, where the material is temporarily stored and prepared for filling. This design not only ensures the stable storage of the foaming material before filling, but also makes the filling operation smoother and more efficient through the buffering effect of the third barrel. At the same time, the precise control of the filling component also ensures that the foaming material can be evenly and accurately filled into the aluminum profile, improving the overall quality and consistency of the product.

[0013] The filling assembly is provided with two groups. The first group of filling assemblies includes a first filling drive, a first liquid inlet tube and a first liquid outlet tube. One end of the first liquid inlet tube is connected to the third barrel body, and the end away from the third barrel body is connected to the first liquid outlet tube body. The first filling drive is connected to the first liquid outlet tube body. The mixed foaming material in the third barrel body flows from the first liquid inlet tube body to the first liquid outlet tube body. The first filling drive transports the foaming material in the first liquid outlet tube body to the filling part of the aluminum profile.

[0014] The filling unit also includes a liquid suction pump and a liquid suction tube body, and the second group of filling components includes a second filling drive, a second liquid inlet tube body, and a second liquid outlet tube body; one end of the liquid suction tube body is connected to the third barrel body, and the end away from the third barrel body is connected to the liquid suction pump, the second liquid inlet tube body is connected to the liquid suction pump, and the end away from the liquid suction pump is connected to the second liquid outlet tube body, the second filling drive is connected to the second liquid outlet tube body, the liquid suction pump extracts the mixed foaming material in the third barrel body from the third barrel body through the liquid suction tube body, the extracted foaming material flows to the second liquid outlet tube body through the second liquid inlet tube body, and the second filling drive transports the foaming material in the second liquid outlet tube body to the filling part of the aluminum profile.

[0015] The first group of filling components directly pushes the foaming material from the third barrel through the first liquid inlet pipe to the first liquid outlet pipe through the first filling drive to complete the filling operation. The second group of filling components innovatively introduces a liquid pump to extract the foaming material from the third barrel through the liquid pumping pipe, and then transports it to the second liquid outlet pipe through the second liquid inlet pipe, and the filling is completed by the second filling drive. This dual-path filling method can not only flexibly select the filling path according to actual needs, but also ensure the continuity of the production process when one group of components is maintained or fails. At the same time, the independent work of the two groups of filling components also greatly improves the filling efficiency, shortens the production cycle, and provides a strong guarantee for the efficient and high-quality production of aluminum profiles.

[0016] A heating unit is also provided inside the rotating shaft. When the rotating shaft rotates, the heating tube heats the foaming material along with the rotating shaft, thereby improving the foaming efficiency.

[0017] The first liquid outlet tube body and the second liquid outlet tube body both include a tube shell and a transmission shaft arranged in the tube shell, and the two groups of transmission shafts are respectively connected to the output ends of the first filling drive member and the second filling drive member; a plurality of groups of integrally formed fan blades are arranged at intervals on the outside of the transmission shaft, and the first filling drive member and the second filling drive member drive the transmission shaft to rotate, and the rotation of the transmission shaft drives the fan blades to rotate to transport the foaming material in the first liquid outlet tube body and the second liquid outlet tube body to the filling part of the aluminum profile.

[0018] The design of the first liquid outlet tube body and the second liquid outlet tube body further reflects the combination of efficiency and innovation. Both adopt a structure in which a transmission shaft is set inside the tube shell, and the transmission shaft is directly connected to the output ends of the first filling drive member and the second filling drive member, ensuring the effective transmission of power. Multiple sets of fan blades are integrally formed on the outside of the transmission shaft. These fan blades rotate when the transmission shaft rotates, playing a role similar to a screw conveyor, effectively pushing the foaming material from the liquid outlet tube body to the filling part of the aluminum profile.

[0019] Two sets of reciprocating and telescopic push rods are provided at one end of the two sets of transmission shafts away from the first filling drive member and the second filling drive member. The two sets of push rods are respectively connected to the output ends of the first filling drive member and the second filling drive member. The first filling drive member and the second filling drive member respectively drive the two sets of push rods to push the foaming material into the filling part of the aluminum profile.

[0020] The two sets of push rods are connected to the output ends of the first filling drive and the second filling drive respectively, which means that they can not only convey the foaming material through the rotation of the transmission shaft and the fan blades, but also further push the material into the filling part of the aluminum profile through the reciprocating extension and contraction of the push rods. This dual-action mechanism ensures that the foaming material can be filled into every corner of the aluminum profile more accurately and efficiently, thereby improving the quality and consistency of the product.

[0021] The heating plate includes a first metal plate, a second metal plate, a first heater and a second heater. The first metal plate and the second metal plate are both semi-cylindrical in shape and have an inner surface formed along the outer surface of the third barrel body; the first heater and the second heater are both semi-cylindrical in shape and in contact with the outer surfaces of the first metal plate and the second metal plate; the thermal insulation layer is a hollow cylindrical shape, and the thermal insulation layer and the metal plate jointly clamp the heater; the first metal plate and the second metal plate respectively protrude a first flange and a second flange outwardly toward the edges on both sides, and the first flange and the second flange are respectively clamped and arranged at the connection between the first heater and the second heater on both sides.

[0022] The heating plate consists of a first metal plate, a second metal plate, a first heater and a second heater. The first metal plate and the second metal plate are both semi-cylindrical in shape, and their inner surfaces are closely fitted to the outer surface of the third barrel, ensuring effective heat transfer. This design not only improves the heating efficiency, but also ensures the uniformity of heating, and avoids the degradation of the foaming material performance due to uneven heat distribution. The first heater and the second heater are also semi-cylindrical in shape, in close contact with the outer surfaces of the first metal plate and the second metal plate. This design not only ensures the maximum transfer of heat, but also makes the shape of the heater perfectly match the metal plate, improving the stability and durability of the structure. The design of the thermal insulation layer further improves the performance of the heating plate. The thermal insulation layer is a hollow cylinder, which clamps the heater together with the metal plate, effectively reducing heat loss and improving heating efficiency. At the same time, the thermal insulation layer also protects the heater and extends the service life of the heater. In terms of structural details, the first metal plate and the second metal plate protrude the first flange and the second flange outward to the edges on both sides respectively. The two flanges are respectively clamped at the connection points on both sides of the first heater and the second heater, which not only ensures the close connection between the heater and the metal plate, but also improves the stability of the structure and avoids the heater from falling off or being damaged due to vibration or external force.

[0023] The mixing unit also includes a sensor monitoring system for real-time detection of the viscosity, temperature and bubble content of the foaming material during the mixing process to ensure that the mixing process reaches the optimal foaming conditions, and feeds back the monitoring data to the central control system for automatic adjustment.

[0024] Beneficial effects of the present invention: The present invention realizes uniform preparation, stable transportation and efficient filling of foamed materials by integrating foamed material storage, efficient mixing and precise filling units. Among them, the mixing unit utilizes variable-pitch spiral blades to enhance the stirring effect, and combines vacuum degassing, temperature-controlled heating and a heating unit built into the rotating shaft to ensure high-quality mixing and efficient foaming of the foamed material; the filling unit adopts a dual-path filling method, combined with the rotation of the fan blades driven by the transmission shaft and the reciprocating extension and contraction of the push rod, to achieve precise and efficient filling of the foamed material. At the same time, the heating plate adopts a semi-cylindrical metal plate that fits tightly with the heater, and cooperates with a hollow cylindrical insulation layer, which not only improves the heating efficiency and uniformity, but also effectively prevents heat loss, further improving energy utilization efficiency and production cost control. This series of innovative designs jointly ensure the efficient and stable operation of the aluminum profile extrusion molding foaming and filling production line, and significantly improves the quality and performance of the product.

The stirring unit 7 includes a first driving member 11, a rotating shaft 12 connected to the output end of the first driving member 11, and a plurality of spiral blades 13 spirally wound on the outer wall of the rotating shaft 12. The spacing between the spiral blades 13 increases continuously from the bottom of the first barrel body 6 to the top of the first barrel body 6.

In specific implementation, the second connecting pipe body 5 stably transports the mixed foaming material from the mixing unit 2 to the inlet 23 of the third barrel 21, and the material is temporarily stored in the barrel and prepared for filling.
