Description

Technical Field

[0001] The utility model relates to the technical field of aluminum composite plate processing devices, in particular to an extrusion device for producing aluminum composite plates. Background Art

[0002] Common composite aluminum plates include copper-aluminum composite plates. Since copper plates and aluminum plates will produce an electrochemical reaction after being welded and energized, an extrusion device is usually used during composite production to press the copper plates and aluminum plates coated with composite glue.

[0003] However, when the existing extrusion device for producing aluminum composite panels applies glue to the surfaces of copper plates and aluminum plates, the metal composite glue applied is in a fluid state, so the glue is easy to overflow from both sides of the composite plate when brushing, which easily causes unnecessary waste of glue; in addition, after the existing extrusion device completes the extrusion, it is usually dried in an air-drying manner to wait for the glue in the interlayer of the composite plate to dry thoroughly, and the natural air-drying method is time-consuming, resulting in a relatively time-consuming production of composite plates in assembly line operations, which increases the time cost of aluminum composite plate production. Utility Model Content

[0004] The purpose of the utility model is to provide an extrusion device for producing aluminum composite panels to solve the problems raised in the above background technology.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figures 1 to 4 As shown, the extrusion device for producing aluminum composite panels in this embodiment includes a base 15, one end of the base 15 is fixedly connected to a first vertical frame 1, a conveying roller 2 is installed on the top of the first vertical frame 1, a second vertical frame 3 is fixedly connected to the middle of the base 15, a glue coating roller 7 is installed on the top of the second vertical frame 3, a horizontal tube 6 runs through the middle of one side wall of the second vertical frame 3, a plurality of nozzles 5 are installed on the top and bottom of the horizontal tube 6, the other end of the base 15 is fixedly connected to a third vertical frame 10, and an extrusion roller 11 is installed on the top of the third vertical frame 10;

[0025] A side box 14 is fixedly connected to the middle of one side wall of the third vertical frame 10, a heat conducting plate 12 is engaged with the top of the side box 14, an air outlet 13 is provided at the top of the heat conducting plate 12, an electric heating plate 18 is installed on the inner wall of the side box 14, fans 21 are installed on both sides of the inside of the side box 14, a top box 9 is fixedly connected to the top of the base 15, and screens 8 are embedded on both sides of the top of the top box 9.

[0026] Specifically, the conveying roller 2 is used to convey the copper plate and the aluminum plate respectively, so that the plates have sufficient spacing before gluing, which is conducive to the subsequent gluing. The gluing roller 7 can roll the mist glue sprayed on the plate by the nozzle 5 again, so that the glue can be drawn, and can absorb and spread the glue accumulated into a fluid state, thereby reducing the probability of the glue in the middle of the plate forming a fluid state. The function of the cross tube 6 is to allow the nozzle 5 to be distributed and arranged horizontally, so that the glue sprayed by the nozzle 5 can be evenly distributed on the plate conveyed by the conveying roller 2, thereby realizing the glue coating. The function of the squeezing roller 11 is to extrude the copper plate and the aluminum plate after glue coating, so that the two are pressed into a composite plate. The top of the side box 14 is located between the two squeezing rollers 11. The heat conducting plate 12 allows the extruded composite board to slide smoothly to the heat conducting plate 12 on the top of the side box 14 to heat up, which is beneficial to the solidification of the glue in the interlayer of the composite board. The heat conducting plate 12 allows the heat of the electric heating plate 18 to be quickly transferred to the composite board, so that the glue in the composite board can be quickly solidified at a higher temperature. The air outlet 13 allows the heat to pass through the heat conducting plate 12 and directly contact the composite board, which is more conducive to the composite board absorbing heat. The fan 21 can accelerate the heat generated by the electric heating plate 18 to be blown out from the air outlet 13, thereby reducing heat loss. The function of the wire mesh 8 is to receive the fluid glue overflowing from both sides of the board and reduce the glue dripping on the base 15, thereby reducing unnecessary waste of glue.

[0027] Furthermore, a glue pump 4 is fixedly installed on the front of the second vertical frame 3, and the output end and input end of the glue pump 4 are both provided with connecting pipes 16. The function of the glue pump 4 is to pass the glue into the horizontal pipe 6, and then make the glue spray out from the nozzle 5 in the form of mist, thereby avoiding the use of brushing to apply the glue.

[0028] Furthermore, the connecting pipe 16 at the output end of the glue pump 4 is connected to the horizontal pipe 6, and a glue storage chamber 17 is provided inside the base 15. The glue storage chamber 17 can temporarily store an appropriate amount of glue and recycle the received glue to save production costs.

[0029] Furthermore, the top box 9 is communicated with the interior of the glue storage chamber 17, the connecting pipe 16 at the input end of the glue pump 4 is communicated with the interior of the glue storage chamber 17, and the top of the top box 9 is also located in the middle of the other side of the two extrusion rollers 11, so that the copper plate and the aluminum plate can be supported by the bottom of the top box 9 after being coated with glue, thereby facilitating the copper plate and the aluminum plate to slide into the extrusion roller 11 for extrusion.

[0030] Furthermore, a rotary motor 20 is fixedly installed at the junction of the third vertical frame 10 and the base 15. The output end of the rotary motor 20 and the shaft end of the extrusion roller 11 are both provided with a gear 19. The function of the gear 19 is to make the two extrusion rollers 11 rotate in opposite directions, thereby realizing the extrusion of the copper plate and the aluminum plate by the extrusion roller 11.

[0031] Furthermore, the gear 19 at the output end of the rotating motor 20 is meshedly connected with the gear 19 at the shaft end of the extrusion roller 11, and the extrusion roller 11 is movably connected to the third vertical frame 10 through the rotating motor 20. The rotating motor 20 can drive the extrusion roller 11 to rotate through the driving gear 19, thereby realizing the extrusion of copper plates and aluminum plates.

[0032] Furthermore, the fan 21 is movably connected to the electric heating plate 18, and the two fans 21 are respectively located on both sides of the electric heating plate 18, so that the heat of the electric heating plate 18 can be quickly blown out from the air outlet 13 in the middle, thereby accelerating the heat transfer.

[0033] The method of using this embodiment is as follows: before using the extrusion device for producing aluminum composite panels, it is necessary to first connect the device to an external power supply. At this time, the gear 19 at the shaft end of the extrusion roller 11 will be driven by the gear 19 at the output end of the rotating motor 20, and then the copper plate and the aluminum plate will pass through the conveying roller 2 respectively and enter the glue coating roller 7 and pass through the extrusion roller 11, and will be at the top and bottom of the glue coating roller 7 respectively. At this time, the glue pump 4 is started, so that the glue pump 4 draws the metal composite glue in the glue storage chamber 17 to the transverse tube 6, and then the glue will be sprayed from the nozzle 5 on the transverse tube 6 in the form of mist, and then fall between the copper plate and the aluminum plate, and then the copper plate and the aluminum plate sprayed with glue will contact the glue coating roller 7, and at this time the glue coating roller 7 will apply the glue on the plate again. The copper plate and the aluminum plate are flat, so that the accumulated fluid glue is evenly distributed on the surface of the copper plate and the aluminum plate, and the fluid glue is not easy to overflow from the two sides of the interlayer. When the copper plate and the aluminum plate enter the squeezing roller 11, the excess glue between the copper plate and the aluminum plate will flow along the gaps on both sides of the interlayer to the two sides of the top of the top box 9. At this time, the wire mesh 8 on the top of the top box 9 will receive the overflowing glue, so that the glue returns to the glue storage cavity 17 through the top box 9. After the copper plate and the aluminum plate are squeezed into a composite plate, they will slide out along the heat conducting plate 12 on the top of the side box 14. At the same time, the fan 21 inside the side box 14 blows out the heat generated by the electric heating plate 18 from the air outlet 13, so that the heat is absorbed by the composite plate, and the glue in the interlayer of the composite plate is quickly solidified.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
