Description

Technical Field

[0001] The invention relates to the technical field of material processing equipment, and in particular to an aluminum-plastic composite board production equipment for embedded light strips. Background Art

[0002] Recently, the architectural decoration industry has begun to popularize simple and light luxury styles, and a large number of lamps have been installed in cabinet furniture to make the cabinet brighter and more convenient to take items. There are more and more styles of lamps in the development of cabinet furniture, which have evolved from the previous way of installing a small lamp in the cabinet to the current way of installing a lamp on each shelf. The installation method of lamps is generally embedded to increase the aesthetics.

[0003] The conventional installation method of embedded light strips is to make grooves on the surface of the board of the cabinet furniture, then apply fixing glue around the grooves, and embed the aluminum alloy light troughs into them before the fixing glue dries. After the fixing glue dries, stick the back of the light strip on the aluminum trough, and finally cover it with a lampshade. The disadvantage of this method is that the board needs to be processed and grooved for a second time, and the aluminum alloy light trough is not firm enough to be fixed with glue, and the aluminum alloy light trough is a major accessory and it is difficult to omit it. At the same time, this method cannot maintain the overall unity and perfection of the building decoration surface, affecting the visual effect.

[0004] Aluminum-plastic composite panels are widely used in cabinet furniture panels due to their light weight, easy installation, good flatness, good weather resistance and rich colors. However, the problem is that embedded light strips cannot be directly installed on the aluminum-plastic composite panels, and only secondary processing by splicing can be used. This not only affects the overall appearance, but also increases the complexity of the process installation.

[0005] If aluminum-plastic composite panels with integrated lamp troughs are processed as needed before they leave the factory, the defect that embedded lamps cannot be directly installed when aluminum-plastic composite panels are used in cabinet furniture can be solved.

[0006] Therefore, it is necessary to design an online production equipment for aluminum-plastic composite panels for embedded light strips. Summary of the invention

[0007] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an aluminum-plastic composite board production device for embedded light strips.

[0008] A technical solution of the present invention to achieve the above object is:

[0009] A production device for aluminum-plastic composite panels for embedded light strips, comprising an aluminum-plastic composite panel strip forming sub-device, a light trough forming sub-device, and a plate shearing sub-device arranged in sequence along the production line; wherein the light trough forming sub-device comprises:

[0010] The plate chain conveyor is used to convey the formed aluminum-plastic composite plate strip along the production line; the aluminum-plastic composite plate includes a bottom aluminum plate, a core plate and a surface aluminum plate bonded to each other from bottom to top;

[0011] A first slotting device is arranged above the plate chain conveying device, and is used to continuously open a first groove along the production line direction on the surface aluminum plate with the end of the aluminum-plastic composite plate strip conveyed thereto as the starting point, so as to expose the surface of the core plate;

[0012] The second slotting device is arranged above the plate chain conveying device and in front of the first slotting device, and is used to hollow out the core plate below the surface aluminum plate with the end of the aluminum-plastic composite plate strip conveyed thereto as the starting point and through the notch of the first groove, so as to continuously open a second groove along the production line direction directly below the first groove to expose the surface of the bottom aluminum plate; wherein the width of the second groove is greater than the width of the first groove, so that the surface aluminum plate located above the second groove has a horizontal hanging portion extending from the notch end of the second groove to the notch end of the first groove;

[0013] The mobile flanging device is arranged above the plate chain conveyor device and in front of the second grooving device. It is used for taking the end of the aluminum-plastic composite board strip conveyed to it as the starting point and performing mobile and repeated downward pressing at a reciprocating speed matching the conveying speed of the plate chain conveyor device. Each downward pressing causes a fixed-length suspended portion connected during movement to bend to a vertical state that fits the cross-section of the core board, and causes the end face of the suspended portion to contact the surface of the underlying aluminum board, thereby forming a lamp trough structure on the entire length of the aluminum-plastic composite board strip.

[0014] Furthermore, the plate chain conveying device is provided with a plurality of power rollers in parallel, and the power rollers are used to drive and convey the aluminum-plastic composite board strip.

[0015] Furthermore, the mobile flanging device is provided with a mobile punch, and the reciprocating speed of the punch matches the driving and conveying speed of the power roller.

[0016] Furthermore, the punch has a punch length corresponding to a fixed length of a section of the hanging portion targeted at each pressing operation, and has a punch width corresponding to a notch of the second groove.

[0017] Furthermore, the punch is in the shape of an inverted terrace, and the trapezoidal side surface of the terrace has an outwardly convex curvature.

[0018] Furthermore, the first slotting device is provided with a straight milling cutter.

[0019] Furthermore, the second slotting device is provided with a T-shaped milling cutter.

[0020] Furthermore, the molding sub-equipment includes:

[0021] Extrusion device, used for continuously extruding core board materials and pre-forming;

[0022] A film sticking device, used for sticking adhesive films on the upper and lower surfaces of the predetermined core plate material;

[0023] The unwinding device is used to unwind the two aluminum coils respectively until they are in contact with the upper and lower surfaces of the core plate material, thereby forming a surface aluminum plate and a bottom aluminum plate on the upper and lower surfaces of the core plate material respectively;

[0024] A thermal composite device is used to heat and laminate the bottom aluminum plate, the core plate and the surface aluminum plate through an adhesive film to form an aluminum-plastic composite plate strip;

[0025] The cooling device is used to cool the aluminum-plastic composite board strip after thermal compounding to form a shaped aluminum-plastic composite board strip.

[0026] Furthermore, a trimming device is provided on the production line between the film laminating device and the unwinding device for online trimming of the edges of the predetermined core plate material so that the width of the core plate material after the edge trimming corresponds to the width of the aluminum coil.

[0027] Furthermore, a protective film sticking device is provided in front of the movable flanging device, a driving traction device is provided between the protective film sticking device and the shearing sub-device, and a finished product collecting device is provided in front of the shearing sub-device.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] (1) By setting up a grooving device and a mobile flanging device online, the original aluminum plate material on the aluminum-plastic composite panel can be directly processed to form a lamp trough structure of an embedded light strip, so that the lamp trough and the aluminum-plastic composite panel surface are seamlessly combined, achieving the overall unity and perfection of the aluminum-plastic composite panel decorative surface and the lamp body, which is visually neater and more beautiful.

[0030] (2) By processing lamp troughs on the aluminum-plastic composite board production line, the defect that the aluminum-plastic composite board cannot be directly installed with embedded lamp bodies when used in cabinet furniture is solved. Compared with the traditional decorative board that uses secondary processing to cut grooves and then fix the aluminum alloy lamp trough with glue, it not only enhances the overall firmness of the lighting facilities, but also saves aluminum alloy lamp trough materials, thus having great market potential.

[0031] (3) By matching the straight milling cutter provided in the first slotting device with the T-shaped milling cutter provided in the second slotting device, and by setting a mobile flanging device to coordinate with the belt speed to perform mobile continuous stamping and flanging, a good connection between the two stampings is achieved, successfully solving the problem of processing the lamp trough in the entire length of the aluminum-plastic composite board strip, avoiding the inconvenience of secondary processing of the aluminum-plastic composite board after cutting to a fixed length, shortening the processing cycle, and saving costs.

[0032] (4) By setting up an online trimming device, the edge of the core plate material after pre-forming can be trimmed online so that the width of the core plate material after the edge is trimmed corresponds to the width of the aluminum coil, avoiding the subsequent overall trimming of the composite aluminum-plastic composite plate strip, and preventing the exposed core plate material from melting due to the excessively high temperature of the composite wheel during the hot composite bonding process, thereby preventing the exposed core plate material from bonding to the hot composite wheel and causing quality accidents. At the same time, it saves the loss of aluminum coils, improves material utilization, and saves production energy consumption for composite of excess materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to better understand the technical solution of the present invention, a detailed description is given below through specific embodiments.

[0040] See also Figure 1 The aluminum-plastic composite board production equipment for embedded light strips of the present invention comprises an aluminum-plastic composite board strip forming sub-equipment, a light trough forming sub-equipment, and a plate shearing sub-equipment which are sequentially arranged along the production line.

[0041] The molding sub-equipment may include an extrusion device 10, a film laminating device 11, an unwinding device 13, a thermal compounding device 14, and a cooling device 15 which are sequentially arranged along the production line.

[0042] In a preferred embodiment, a trimming device 12 may be further provided on the production line between the film laminating device 11 and the unwinding device 13 .

[0043] The lamp trough forming sub-equipment may include a first grooving device 16, a second grooving device 17, and a movable flanging device 18 which are sequentially arranged along the production line.

[0044] In addition, a protective film sticking device 19 and a driving traction device 20 may be sequentially provided on the production line between the mobile flanging device 18 and the shearing sub-device 21 ; a finished product collecting device 22 may also be provided in front of the shearing sub-device 21 .

[0045] A plate chain conveying device is also provided between the cooling device 15 , the first slotting device 16 , the second slotting device 17 and the movable flanging device 18 .

[0046] Thus, in a preferred embodiment, an aluminum-plastic composite panel production device for embedded light strips of the present invention may include: an extrusion device 10, a film pasting device 11, a trimming device 12, an unwinding device 13, a thermal composite device 14, a cooling device 15, a first slotting device 16, a second slotting device 17, a mobile flanging device 18, a protective film pasting device 19, a driving traction device 20, a shearing sub-device 21, and a finished product receiving device 22 arranged in sequence along the production line, such as Figure 1 shown.

[0047] At the same time, multiple plate chain conveying devices can be configured, which can be set not only on the production line between the cooling device 15, the first slotting device 16, the second slotting device 17 and the mobile flanging device 18, but also on other necessary stations of the production line, such as between the film pasting device 11 and the unwinding device 13, between the thermal composite device 14 and the cooling device 15, between the mobile flanging device 18 and the protective film pasting device 19, between the shearing sub-device 21 and the finished product receiving device 22, etc. In addition, each plate chain conveying device can be synchronously driven or individually driven.

[0048] See also Figure 1 The extrusion device 10 is used to continuously extrude the core board material, for example, PE (polyethylene) plastic particles can be extruded to obtain a predetermined PE plastic core board. The predetermined PE plastic core board is finally shaped in the subsequent composite process with aluminum material to become a high-pressure low-density PE plastic core board.

[0049] The core board material may also be other commonly used fireproof core materials.

[0050] The extrusion device 10 may be an extruder.

[0051] The film pasting device 11 includes two film pasting machines, such as heat pasting machines, arranged on the upper and lower sides of the predetermined core board, for continuously pasting adhesive films on the upper and lower surfaces of the continuously extruded predetermined core board material.

[0052] The adhesive film may be, for example, a polymer adhesive film, which has excellent adhesive force when hot-melted.

[0053] See also Figure 2 In a preferred embodiment, the trimming device 12 is arranged on both sides above the output core plate 232 strip after film lamination, and includes two cutters (edge ​​cutting knives) 121, which are used to perform online cutting of the edges of the core plate 232 material after pre-forming and film lamination, so that the width of the core plate 232 material after edge cutting corresponds to the width of the subsequent aluminum coil.

[0054] Affected by the production environment of thermal expansion and contraction and the vibration accuracy error of the equipment, the PE plastic core plate 232 extruded by the extruder requires the width of the extruded core plate 232 to be adjusted to about 20mm wider than the standard setting width, and the upper and lower polymer adhesive films are pasted by the film pasting wheel of the thermal pasting machine, and then cooled and shaped, and then thermally composited with the upper and lower aluminum coils of the next process. The purpose of adjusting the width of the extruded core plate 232 to 20mm wider than the standard setting width is to ensure that the upper and lower polymer adhesive films can be completely pasted to the surface of the plastic core plate 232 during the film pasting process.

[0055] Such conventional production process requires that the upper and lower aluminum coils in the subsequent process should also be loosened by 20mm to completely cover the plastic core plate 232 after bonding, so as to prevent the excessively high temperature of the composite wheel from melting the exposed PE plastic core plate 232 beyond the specification during the thermal composite bonding process, thereby causing the exposed PE core plate 232 to be bonded to the thermal composite wheel and cause quality accidents. However, the upper and lower aluminum coils that are loosened by 20mm must be sheared and wasted in the shearing process later, resulting in a waste of materials and energy consumption.

[0056] The characteristic of setting the trimming device 12 is that after the PE plastic core plate 232 is extruded by the extruder, the upper and lower polymer adhesive films are attached by the film attaching wheel of the heat attaching machine and then cooled and shaped, before the upper and lower aluminum coils are attached in the subsequent process, a set of trimming knife mechanisms that can adjust the distance and angle are installed to accurately cut the size of the core plate 232 to the standard size. In this way, the subsequent upper and lower aluminum coils can be bonded and laminated at high temperature using standard specifications and sizes. The advantage is that it not only saves the loss of aluminum coils, improves the material utilization rate, but also saves the production energy consumption of 20mm material composite.

[0057] In a preferred embodiment, the direction of the blade of the cutter 121 can be adjusted to an angle of 45 degrees to the opposite direction of the core plate 232, while ensuring that the blade can completely cut through the core plate 232.

[0058] The core board 232 is driven by the front pulling force on the core board 232 conveying shaft to move forward at a constant speed. The excess core boards 232 on both sides exceeding the standard set width are continuously and automatically cut off at the position of the cutter 121 and fall into the core board collection box for recovery.

[0059] In this way, the cut PE plastic core plate 232 and the subsequent upper and lower aluminum coils can be bonded and laminated at high temperature using standard specifications and sizes. In addition, the two side end surfaces of the trimmed PE plastic core plate 232 become smooth and flat.

[0060] See also Figure 1 The unwinding device 13 includes two unwinding machines, such as unwinding machines, arranged on the upper and lower sides of the core plate 232 after the output film is laminated, for unwinding the two aluminum coils to fit the upper and lower surfaces of the core plate 232 material, thereby forming a surface aluminum plate 233 and a bottom aluminum plate 231 on the upper and lower surfaces of the core plate 232 material (refer to Figure 3 ).

[0061] The heat-compounding device 14 includes a plurality of heat-compounding wheels arranged on the upper and lower sides of the plate strip having a sandwich structure of a bottom aluminum plate 231, a core plate 232 and a surface aluminum plate 233 output after unwinding, and is used to heat the bottom aluminum plate 231, the core plate 232 and the surface aluminum plate 233 to form an aluminum-plastic composite plate strip 23 (reference Figure 5 ).

[0062] The cooling device 15 includes a plurality of fans arranged in a box body, and is used to cool the output hot aluminum-plastic composite board strip 23 from the upper and lower sides to form the aluminum-plastic composite board strip 23 after final shaping.

[0063] In a preferred embodiment, the plate chain conveying device arranged in the lamp trough forming sub-equipment area may include a plate chain conveyor, which is provided with multiple power rollers in parallel and driven by the power rollers for conveying the aluminum-plastic composite board strip 23.

[0064] In a preferred embodiment, the first slotting device 16 and the second slotting device 17 may include two engraving devices, such as two engraving machines, which are separately arranged above the running line of the plate chain conveyor.

[0065] The engraving machine is equipped with a CNC computer equipped with engraving control software to coordinate and control the various hardware mechanisms of the engraving machine. It also includes an electrical control cabinet, which can directly drive the engraving machine to produce mechanical movement according to the control instructions sent by the CNC computer, and detect various states of the engraving machine, and feed back to the CNC computer and control software for identification and processing.

[0066] The engraving machine includes a first engraving machine belonging to the first slotting device 16 and a second engraving machine belonging to the second slotting device 17 .

[0067] The first engraving machine is used to continuously open the first groove 241 along the production line direction on the surface aluminum plate 233 with the end of the aluminum-plastic composite plate strip 23 delivered as the starting point (reference Figure 5 ), exposing the surface of the core plate 232.

[0068] When the first groove 241 is opened, the first engraving machine is set first: according to the standard position of the light bar installation required by the order, the fixed-point engraving position setting and the groove opening depth setting are performed.

[0069] See also Figure 3 In a preferred embodiment, the first engraving machine can be equipped with a straight milling cutter 161, such as a straight groove alloy milling cutter. The slotting depth setting needs to ensure that the slotting depth exceeds the thickness of the surface aluminum plate 233. The selection standard of the cutter head diameter size refers to the lamp slot 24 to be opened (reference Figure 6 ) is determined by the width of the

[0070] When the first engraving machine is slotting the surface aluminum plate 233, the power roller of the plate chain conveyor drives the front end of the aluminum-plastic composite board strip 23 to move forward to the bottom of the first engraving machine. The first engraving machine uses a straight groove alloy milling cutter to perform fixed-point slotting. The aluminum-plastic composite board strip 23 is driven by the power roller and pulled by the driving traction device 20 in front of the production line. When passing through the high-speed straight groove alloy milling cutter, a straight groove of the first groove 241 is automatically formed on the surface aluminum plate 233 of the aluminum-plastic composite board strip 23.

[0071] The second engraving machine is used to hollow out the core plate 232 below the facing aluminum plate 233 by taking the end of the aluminum-plastic composite plate strip 23 delivered to the conveyor as the starting point, and through the notch of the first groove 241, to continuously open the second groove 242 along the production line direction directly below the first groove 241 (refer to Figure 6 ), exposing the surface of the underlying aluminum plate 231.

[0072] See also Figure 4In a preferred embodiment, the second engraving machine may be equipped with a T-shaped milling cutter 171, for example, a straight shank T-slot alloy milling cutter. The slotting depth setting needs to ensure that the slotting depth does not damage the bottom aluminum plate 231. After slotting, the core material of the core plate 232 at the edges on both sides is exposed. The thickness of the cutter head is selected to be equivalent to the thickness of the plastic core plate 232 in the aluminum-plastic composite board, and the diameter of the cutter head is selected according to the width of the light trough 24 required when the light bar is finally installed.

[0073] When the second engraving machine is slotting (hollowing out) the plastic core plate 232, the power roller of the plate chain conveyor drives the front end of the aluminum-plastic composite board strip 23 to move forward to the position directly below the second engraving machine. The second engraving machine uses a straight-shank T-slot alloy milling cutter to perform fixed-point slotting along the position of the straight groove (first groove 241). The aluminum-plastic composite board strip 23 is driven by the power roller and pulled by the driving traction device 20 in front of the production line. When passing through the high-speed straight-shank T-slot alloy milling cutter, a T-slot is automatically processed on the middle plastic core plate 232 of the aluminum-plastic composite board strip 23. The T-slot includes a second groove 242 located in the core plate 232 layer and a first groove 241 connected to the surface aluminum plate 233 layer located directly above the second groove 242.

[0074] The width of the second groove 242 is greater than that of the first groove 241, so that the surface aluminum plate 233 located above the second groove 242 has a horizontal hanging portion 2331 extending from the notch end of the second groove 242 to the notch end of the first groove 241. The length of the hanging portion 2331 corresponds to the thickness of the core plate 232.

[0075] The mobile flanging device 18 is used to take the end of the conveyed aluminum-plastic composite board strip 23 as the starting point, and to move repeatedly downward at a reciprocating speed matching the conveying speed of the plate chain conveyor. Each downward pressure causes a fixed length (for example, 1000mm) of the suspended portion 2331 connected in the movement to bend to a vertical state that fits the cross-section of the core plate 232, and makes the end face of the suspended portion 2331 contact with the surface of the underlying aluminum plate 231, thereby forming a lamp trough 24 structure on the entire length of the aluminum-plastic composite board strip 23.

[0076] In a preferred embodiment, the mobile flanging device 18 may include a mobile high-speed punching machine arranged above the running line of the plate chain conveyor. The straight-line moving distance of the punching machine along the production line is, for example, 2000 mm. The mobile flanging device 18 also includes a positioning sensing system, which adopts an xy-axis four-way positioning setting and is installed on both sides of the plate chain conveyor. And includes a numerical control computer to coordinate and control the positioning sensing system and various hardware mechanisms of the punching machine. It also includes an electrical control cabinet, which directly drives the punching machine to produce mechanical movement according to the control instructions sent by the numerical control computer, and detects various states of the punching machine, and feeds back to the numerical control computer and control software for identification and processing.

[0077] The positioning sensing system can adopt absolute positioning technology and is equipped with an absolute positioning sensor to sense the front edge of the plate strip. Two groups of four aluminum coil edge tracking sensors are installed on both sides of the plate chain conveyor running line, and the edge tracking sensors are connected to the positioning sensing system.

[0078] The first group of 2 aluminum coil edge tracking sensors are connected on the same horizontal line to form an X linear axis, which is arranged on both sides of the plate chain conveyor running line, and the position is consistent with the starting position of the straight-line movement distance of the punch press; the second group of 2 aluminum coil edge tracking sensors are also connected on the same horizontal line to form an X linear axis, which is arranged on both sides of the plate chain conveyor running line, and the position is kept at an accurate straight-line distance of 1000mm from the starting position of the straight-line movement distance of the punch press. In this way, the distance between two adjacent aluminum coil edge tracking sensors on one side of the plate chain conveyor running line is 1000mm, forming a Y linear axis on each side.

[0079] When the front end of the aluminum-plastic composite board strip 23 with the aluminum skin exposed after slotting moves to the punching machine station, the first group of two aluminum coil edge tracking sensors detect the aluminum skin and feedback to the positioning sensing system to locate the starting position. When the second group of two aluminum coil edge tracking sensors detect the aluminum skin, they feedback to the positioning sensing system. At this time, the distance between the two groups of edge tracking sensors is exactly the same as the punch length (i.e., fixed length) of the punching machine. The positioning sensing system feedbacks to the CNC computer (host), and the control instructions sent by the CNC computer directly drive the punching machine to produce mechanical movement. The punching machine starts the first mobile punching from the moving starting position (punching out a hanging part 2331 with a fixed length of 1000mm). After the punching machine completes the first punching, it quickly returns to the starting position and starts punching again (punching out a second hanging part 2331 with a fixed length of 1000mm, and connecting the first hanging part 2331 with a fixed length of 1000mm).

[0080] When the punching machine is performing mobile punching, the punching machine is set up first: the fixed-point punching setting is performed according to the standard position of the light bar installation required by the order, and the position setting is consistent with the slotting fixed-point setting; the moving speed of the punching machine is consistent with the line speed setting of the production line; the punching machine is adjusted to the side of the second engraving machine.

[0081] See also Figure 5 In a preferred embodiment, the punching machine is provided with a special mold, for example, a movable special guide punch 181, and the reciprocating speed of the punch 181 matches the driving conveying speed (linear speed) of the power roller. The punch 181 can be in an inverted terrace shape, and the trapezoidal side of the terrace has a convex arc.

[0082] The punch 181 has a length of the punch 181 corresponding to the fixed length of a section of the hanging portion 2331 targeted at each time of pressing, and has a width of the punch 181 corresponding to the notch of the second groove 242. For example, the length of the punch 181 can be 1000 mm. The width of the lower terrace of the punch 181 is preferably about 1 to 2 mm smaller than the diameter of the T-slot slot, and the width of the upper terrace of the punch 181 is preferably about 0.1 mm smaller than the diameter of the T-slot slot.

[0083] When the punching machine is punching, the pressure of the punch press changes the shape (angle) of the hanging portion 2331 retained at the groove of the surface aluminum plate 233 of the metal composite plate through the punch 181, so that the hanging portion 2331 of the surface aluminum plate 233 is continuously moved closer to the cross-section of the plastic core plates 232 on both sides until it is tightly fitted with the exposed core material surface, so as to achieve the effect of covering the exposed core material.

[0084] During stamping production, when the positioning sensing system senses that the front end of the aluminum-plastic composite board strip 23 after slotting reaches the position directly below the punch 181 of the punching machine, the control starts the mobile stamping. The punching machine performs stamping at an average speed of no more than 20 mm / s. After the stamping is in place, it is statically pressed for a few seconds, and then the punch 181 is lifted, and the punching machine returns to its original position to continue the second mobile stamping. That is, during stamping production, the hanging part 2331 on the entire length of the upper aluminum plate 233 of the moving strip is continuously stamped and bent in sections, and this is repeated until the tail end of the strip. Moreover, during each stamping, the punch 181 moves forward 1000mm synchronously with the aluminum-plastic composite board strip 23, and completes a complete stamping step during the movement to form a lamp trough section with a fixed length of 1000mm, and then lifts up and retreats to the initial position for a second synchronous movement stamping to continue to form a new lamp trough section with a fixed length of 1000mm, and the two lamp trough sections formed by the two stampings are connected end to end.

[0085] In a preferred embodiment, a protective film sticking device 19 may be provided on the production line in front of the punching machine, such as a conventional film sticking machine.

[0086] In a preferred embodiment, a driving and traction device 20 may be provided on the production line between the protective film sticking device 19 and the shearing sub-device 21, such as a conventional driving and traction machine.

[0087] The shearing sub-equipment 21 may include a conventional sizing shearing machine.

[0088] In addition, a finished product receiving device 22 may be provided in front of the shearing sub-equipment 21 for receiving and stacking the finished aluminum-plastic composite panels having an integrated lamp trough 24 structure and used for embedded light strips after being cut to a fixed length by the shearing machine.

[0089] See also Figure 6, which shows a finished structure of an aluminum-plastic composite panel for an embedded light strip processed by the aluminum-plastic composite panel production equipment for an embedded light strip of the present invention.

[0090] In a preferred embodiment, the finished aluminum-plastic composite panel for embedded light strips includes, from bottom to top, a bottom aluminum plate 231, a core plate 232, and a surface aluminum plate 233 bonded by thermal bonding, and a lamp trough 24 is processed downward from the surface of the surface aluminum plate 233, and the bottom surface of the lamp trough 24 is used to install the embedded light strip.

[0091] The two sides of the lamp trough 24 are covered with the hanging parts 2331 (aluminum material) of the surface aluminum plate 233 after the above-mentioned stamping and flanging, and the bottom surface of the lamp trough 24 is formed by the upper surface of the exposed bottom aluminum plate 231. Since the reserved length of the hanging parts 2331 corresponds to the thickness of the core plate 232 when the trough is opened, the hanging parts 2331 can completely cover the core plate 232 after stamping and bending, so as to avoid the core material of the core plate 232 being exposed. At the same time, the cross section of the core plate 232 also plays a good supporting role for the hanging parts 2331, thereby preventing the deformation of the lamp trough 24.

[0092] Therefore, the present invention realizes a new technology for online processing of lamp troughs 24 on aluminum-plastic composite panels, reducing the burden of secondary processing on cabinet furniture companies. In addition, the finished aluminum-plastic composite panel with an integrated lamp trough 24 structure and used for embedded light strips produced by the present invention can maintain the overall unity and perfection of the building decoration surface, can be seamlessly combined with the decorative panel surface, and is more neat and beautiful visually.

[0093] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
