Description

Technical Field

[0002] Aluminum composite panels are widely used in building curtain walls, interior decoration, advertising signs, transportation and other fields because of their light weight, high strength, corrosion resistance and excellent processing performance. Aluminum composite panels are generally made of two layers of aluminum plates and a layer of polyethylene or mineral core material through extrusion molding, heating and compounding, and cooling and shaping. The manufacturing process of these aluminum composite panels has high requirements for equipment and process control, especially the extrusion molding process. The precise extrusion molding of aluminum plates and core materials is the key to ensuring product quality; traditional extrusion molding equipment often lacks precise adjustment devices in the design of extrusion rollers and pressure roller systems, resulting in uneven force on the material during the extrusion process. The thickness and surface flatness of the aluminum composite plate after molding are difficult to guarantee, affecting product quality; traditional extrusion molding devices are usually composed of multiple independent components, including independent heating systems, cooling systems and pressure roller systems. These components are independent of each other, with a complex overall structure, occupying a large space and being difficult to install and maintain; during the production process, the extrusion rollers, heating system and cooling system need to be frequently adjusted according to material properties and process requirements; traditional equipment usually uses manual adjustment, which is not only time-consuming and labor-intensive, but also has low adjustment accuracy and is difficult to achieve precise control; the heating and cooling systems of traditional equipment have high energy consumption and lack efficient heat energy utilization and cooling methods, which increases production costs.

The long press rollers 44 and the upper roller member 21 are installed on a horizontal plane.

[0047] A side plate frame 45 is inserted on the side of the double plywood 42 away from the long pressure roller 44, and the end of the side plate frame 45 away from the double plywood 42 is inserted with the short threaded rod. The cold guide plate 41 is installed and lifted with the frame 1 through the side plate frame 45 and the short threaded rod as well as the servo motor 24 and the long screw rod 25. The side of the cold guide plate 41 away from the refrigeration fan 43 is provided with oblique air outlets 47 at equal intervals. The output end of the refrigeration fan 43 is connected to the oblique air outlets 47 through the cold guide plate 41. Both ends of the long pressure roller 44 are connected with cooling water pipes 46, one for inputting cooling water and the other for outputting cooling water, and the cooling water pipe 46 is used for an external cooling system.

[0048] When in use, the aluminum composite material including the aluminum plate and the core material enters the extrusion molding device through the feeding device, and then the connecting rod 27 is connected to an external power source, and the electric heater 28 electrically heats the interior of the upper roller 21 and the lower roller 22, and the aluminum composite material that is about to enter between the upper roller 21 and the lower roller 22 is heated by heat conduction to make the material reach a suitable extrusion temperature, and the temperature sensor 23 monitors the heating temperature in real time, and transmits the temperature data to the control system of the extrusion molding device through the temperature sensor 23 to ensure that the temperature is within the set range; then the extrusion mechanism 2 is activated to deliver the material from the feeding device to the The aluminum composite material between the upper roller 21 and the lower roller 22 is extruded, and the pressure parameters are set by activating the servo motor 24 to push the upper roller 21 to extrude the aluminum composite material, so that the material is formed between the extrusion rollers; the extruded aluminum composite material enters between the lower cold press roller assembly 3 and the upper cold press roller assembly 4, and the long press rollers 44 on the lower cold press roller assembly 3 and the upper cold press roller assembly 4 contact the surface of the material, and the first hydraulic cylinder 7 adjusts the vertically upward pressure applied by the lower cold press roller assembly 3, and under the cooperative roller pressure of the upper cold press roller assembly 4, the surface flatness and thickness uniformity of the aluminum composite material are ensured.

[0049] At the same time, before the extruded aluminum composite plate enters between the lower cold press roller assembly 3 and the upper cold press roller assembly 4, the cooling water pipe 46 connected to the lower cold press roller assembly 3 and the upper cold press roller assembly 4 is connected to the cooling system in advance, and the lower cold press roller assembly 3 and the upper cold press roller assembly 4 are installed at the outlet of the extrusion mechanism 2 in an upper and lower symmetrical shape, so as to use two rows of parallel long press rollers 44 to simultaneously perform water cooling and heat dissipation on the extruded aluminum composite plate. During this period, by simultaneously starting the refrigeration fan 43, the oblique air outlet 47 opened on the surface of the cold guide plate 41 continuously transmits the cold air flow through the long press roller 44 to the extruded aluminum composite plate, and the extruded aluminum composite plate is subjected to secondary air cooling and cooling treatment, so that the extruded aluminum composite plate can be quickly shaped and stabilized in size. Through the above operations, the extrusion forming process of the aluminum composite plate is completed.

[0050] When the composite material is heated and extruded by the extrusion mechanism 2, the spherical phase change material 211 made of phase change material can balance the temperature of the upper roller 21 by itself, utilizing the property of the phase change material to absorb heat when the temperature rises and release heat when the temperature drops, thereby ensuring the uniformity of the heating of the aluminum composite material by the extrusion mechanism 2, ensuring the quality of the extrusion molding of the aluminum composite material, and effectively improving the quality and efficiency of the extrusion molding of the aluminum composite material by the extrusion mechanism 2.

[0051] During the use of the extrusion mechanism 2, the servo motor 24 can be used to drive the long lead screw 25 to rotate, so as to drive the upper roller 21 to be raised and lowered in the frame 1 of the frame 1 through the bolt fastener 29 threadedly mounted on the long lead screw 25, so as to change the distance between the upper roller 21 and the lower roller 22, thereby realizing the extrusion forming operation of the upper roller 21 and the lower roller 22 on the aluminum composite plates of different thicknesses.

[0052] During the use of the extrusion mechanism 2, not only can the aluminum composite material be pressurized and formed by the upper roller 21 and the lower roller 22, but the upper roller 21 can also be heated from the inside out by the electric heater 28 installed on the inner side of the upper roller 21, so that the extrusion mechanism 2 can heat and roll the aluminum composite material at the same time, achieving the dual effects of uniform rolling and heating. At the same time, the extrusion mechanism 2 in the prior art is combined with the heating mechanism, which saves the space occupied by the structure and reduces the overall size of the extrusion molding device, while also achieving a uniform and stable heating effect on the aluminum composite material.

[0053] The upper cold press roller assembly 4 is assembled with the upper roller member 21 through the side plate frame 45, so that the upper cold press roller assembly 4 can be synchronously lifted and lowered following the lifting and lowering adjustment of the upper roller member 21 on the frame 1, and the long press roller 44 can be synchronously lifted and lowered following the upper roller member 21 on the same plane, so as to be combined with the lower cold press roller assembly 3 to cool down and roll the aluminum composite plate after extrusion.

[0054] During the use of the lower cold pressing roller assembly 3 and the upper cold pressing roller assembly 4, not only can the extruded aluminum composite plate be cooled by circulating water through the long pressing roller 44, but the extruded aluminum composite plate can also be cooled by air through the coordinated use of the cold guide plate 41, the double clamping plate 42, the cooling fan 43 and the inclined air outlet 47. On the one hand, the extruded aluminum composite plate is flattened by two rows of long pressing rollers 44 to ensure the flatness and smoothness of the aluminum composite plate, and on the other hand, the aluminum composite plate is subjected to a double-effect cooling treatment to further reduce the temperature of the aluminum composite plate and ensure its dimensional stability and surface quality.

[0055] During this period, the first hydraulic cylinder 7 is activated to vertically lift the lower cold press roller assembly 3 so that the lower cold press roller assembly 3 moves along the slide cavity 101 and approaches the upper cold press roller assembly 4 on the frame 1. The flattening force is adjusted to pressurize the surface of the aluminum composite plate, thereby ensuring the thickness and flatness of the aluminum composite material and improving the forming quality of the aluminum composite plate after extrusion.

[0056] Through the above operation, it can be known that the extrusion molding device has a compact overall design, occupies a small space, is easy to install and use, can provide uniform and stable heat, ensure that the aluminum composite material is extruded and molded at an appropriate temperature, prevent the material from being overheated or overcooled, can provide precise extrusion force through the first hydraulic cylinder 7, ensure that the thickness and shape of the aluminum composite material are consistent, can flatten the surface of the material through a pair of cold pressing roller assemblies, ensure that the surface of the aluminum composite plate is smooth and flat, and meet high quality requirements; can combine water cooling and air cooling to quickly reduce the temperature of the formed aluminum composite plate to ensure its dimensional stability and surface quality, can realize the automation of the extrusion, heating, cooling and flattening processes, is easy to operate, improves production efficiency and product quality, and significantly improves production efficiency and product quality.

A movable cavity 53 is opened through the side of the surface of the arc plate 51 away from the large hole 52, and the upper roller 21 is movably installed with the arc plate 51 through the movable cavity 53.

The front rod 55 has the same structure as the rear rod 54. The rear rod 54 includes a servo motor 541 embedded in the frame 1.

The two arc plates 51 are installed in an opening and closing manner with the frame 1 through the cooperation of the servo motor 541 and the bidirectional threaded screw 542.

[0059] When in use, by activating the servo motor 2 541 to drive the bidirectional threaded screw 542 to rotate clockwise, it can drive a pair of arc plates 51 to approach each other and close to the middle of the frame 1 while activating the rear rod 54 and the front rod 55 at the same time, thereby reducing the width of the guide section of the composite material, thereby controlling the width of the aluminum composite plate extruded by the extrusion mechanism 2. Combined with the free adjustment function of the servo motor 1 24 for the extrusion thickness of the aluminum composite plate, the pressurized forming device can realize the extrusion forming operation of aluminum composite plates of different thicknesses and widths.

[0063] The first electric telescopic rod and the second electric telescopic rod are activated in sequence to perform a movement of first extending and then retracting. When the first electric telescopic rod retracts, the second electric telescopic rod is synchronously activated to extend. When the second electric telescopic rod retracts, the first electric telescopic rod is connected to extend. The operation is cyclically performed in this way. Under the guidance of the structure in which the ball head 67 rotates around the locating pin at the bottom of the bucket plate 66, the sleeve roller 63 can actively push the aluminum composite material guided by the feeding device to the extrusion mechanism 2, thereby helping to speed up the feeding speed of the aluminum composite material between the upper roller member 21 and the lower roller member 22, and while helping the aluminum composite material to quickly enter the extrusion process, the extrusion forming efficiency of the aluminum composite material by the extrusion mechanism 2 is improved, and the uniformity and continuity of the aluminum composite material entering the extrusion mechanism 2 are ensured.

[0064] When the second electric telescopic rod and the first electric telescopic rod are activated in sequence to perform a movement of first extending and then retracting, and when the second electric telescopic rod is extended, the first electric telescopic rod is synchronously activated to retract, and when the first electric telescopic rod is extended, the second electric telescopic rod is connected to retract, and the operation is cyclically performed. Under the guidance of the structure in which the ball head 67 rotates around the locating pin at the bottom of the bucket plate 66, the sleeve roller 63 can actively push part of the aluminum composite material back to the feeding device, thereby realizing the lagging push and conveying of part of the aluminum composite material, and can reduce the total amount of aluminum composite material fed into the extrusion mechanism 2 per unit area according to the required thickness of the aluminum composite plate, thereby realizing the auxiliary material control function of the extrusion molding of the aluminum composite plate, preventing the uniformity of the thickness of the aluminum composite plate caused by excessive use of aluminum composite materials, and eliminating unnecessary workload for the subsequent uniform rolling of the thickness of the aluminum composite plate, thereby playing a role in assisting in improving the extrusion molding efficiency of the aluminum composite plate.

[0065] By combining the two usage modes of the material shifting assembly 6 with the second hydraulic cylinder 8 on the sleeve roller 63, the material shifting assembly 6 as a whole can not only assist in accelerating the efficiency of extruding and conveying the aluminum composite material to the extrusion mechanism 2, but can also adaptively help the extrusion molding device to control the total amount of aluminum composite material entering the extrusion mechanism 2 per unit time according to the specific thickness of the aluminum composite plate to be manufactured, so as to facilitate the subsequent adjustment of the flatness of the aluminum composite plate after extrusion molding, reduce the subsequent workload, and improve the operating efficiency of the extrusion molding device.

[0066] During the use of the material-selecting assembly 6, the motorized roller 62 can be used to drive the sleeve roller 63 to rotate, and the sleeve roller 63 can be used to rotate around the motorized roller 62 to increase the flexibility of the sleeve roller 63. This allows the sleeve roller 63 to push part of the aluminum composite material toward the feeding device or toward the extrusion mechanism 2, thereby further accelerating the efficiency of the sleeve roller 63 in pushing the aluminum composite material. At the same time, it also plays a role in smoothing and organizing the aluminum composite material, preventing part of the aluminum composite material from passing over the top of the surface of the upper roller 21 and not fully participating in the extrusion molding process, thereby ensuring that the aluminum composite material can be completely guided into the extrusion mechanism 2 and extruded smoothly.

[0067] At the same time, during the telescopic adjustment of the second hydraulic cylinder 8, the pushing and rolling depth of the electric roller 62 in the aluminum composite material conveyed by the feeding device can be changed autonomously, and the aluminum composite material that is about to enter the extrusion mechanism 2 can be smoothed in advance, and the flatness of the top of the aluminum composite material entering the extrusion mechanism 2 can be smoothed, so that the aluminum composite material can be smoothly extruded and formed by the extrusion mechanism 2, eliminating the defects that may occur during the extrusion forming of the aluminum composite material by the extrusion mechanism 2, and ensuring the quality of the aluminum composite plate after extrusion forming.
