Description

Technical Field

[0001] The invention relates to the technical field of layered product composite technology, in particular to continuous composite equipment and a composite method for producing aluminum-plastic composite panels. Background Art

[0002] Aluminum-plastic composite panels are a new type of decorative material, mainly made of aluminum and plastic. Depending on the specific application scenario and application requirements, the material combination of aluminum-plastic panels is also different. Taking interior decoration wall panels as an example, honeycomb aluminum panels are often used as core materials, and stone-plastic panels are compositely bonded on both sides of the core material. The surface of the composite panel formed in this way has the characteristics of beautiful and flatness. At the same time, honeycomb aluminum can have good heat insulation, noise reduction, lightweight and other characteristics. The production and processing system of the above-mentioned type of aluminum-plastic mainly includes the gluing work of the two panels, the positioning and stacking of the panels and core panels, the compounding of the hot pressing compounding machine, and the necessary maintenance and cutting work after compounding.

[0003] The current plate composite equipment includes one-time pressing equipment and continuous pressing equipment. The one-time pressing equipment mainly realizes pressing by driving the pressing plate downward through a hydraulic cylinder. After the pressing is completed, the pressing plate is controlled to move upward again and the plate is put back in. The continuous pressing equipment realizes pressing through a belt conveyor and an internal pressing roller, and can continuously put in the plate, which significantly improves the processing efficiency. Chinese patent application CN114714741A discloses a forming device for aluminum honeycomb composite panels, which can apply uniform pressing force to improve the pressing efficiency, but there are still certain shortcomings: the above-mentioned device and the existing continuous pressing equipment can only realize the continuity of the composite work. Since the composite of the plate cannot be loaded through a feeder like a flexible membrane material, the preparation work before the composite still needs to be done manually, and the core plate and the two substrates need to be manually stacked in advance. The manual operation efficiency is limited and the error is large, and it is difficult to ensure the efficiency and composite quality of continuous production.

DETAILED DESCRIPTION

[0039] The mounting frame 2 is sequentially installed with a lower plate conveyor 5, a core plate conveyor 6 and an upper plate conveyor 7 from bottom to top, the output end of the lower plate conveyor 5 corresponds to the input end of the transfer conveyor 3, and the output end of the transfer conveyor 3 corresponds to the input end of the compound machine body 1;

[0040] The top of the lower plate conveyor 5 is provided with a lower glue spraying assembly 8, the bottom of the upper plate conveyor 7 is provided with an upper glue spraying assembly 9, and the upper plate conveyor 7 is also provided with a fixed glue spraying assembly 10 at one end close to the compound machine body 1;

[0041] The grabbing mechanism 4 comprises a base plate 41 capable of horizontal and vertical movement, a suction cup 42 and a clamp 43 are arranged on the base plate 41, and the grabbing mechanism 4 is used to grab the core plate and the upper plate;

[0042] The lower plate conveyor 5, the core plate conveyor 6, the upper plate conveyor 7 and the transfer conveyor 3 are operated to drive the lower plate, the core plate and the upper plate to move toward the compound machine body 1 successively, and at the same time, the lower glue spraying assembly 8 is operated to spray glue on the top surface of the lower plate, and the upper glue spraying assembly 9 is operated to spray glue partially on the bottom surface of the upper plate;

[0043] When the lower plate is transported to the surface of the transfer conveyor 3, the grabbing mechanism 4 operates to clamp the core plate and stack it on the lower plate, and then the grabbing mechanism 4 operates again to grab the upper plate and move it along the conveying direction of the upper plate, while the fixed glue spraying assembly 10 operates to spray glue on the glue-free part of the upper plate, and then the grabbing mechanism 4 stacks the upper plate on top of the core plate;

[0044] The transfer conveyor 3 operates, forcing the stacked composite plates to move into the composite machine body 1;

[0045] Among them, the lower plate and the upper plate in this embodiment are both set to stone plastic plates with smooth surfaces, the core plate is set to a honeycomb aluminum plate, the transfer conveyor 3 is set to a belt conveyor, the lower plate conveyor 5 and the core plate conveyor 6 are both set to roller conveyors, the upper plate conveyor 7, the lower plate conveyor 5 and the core plate conveyor 6 have the same conveying direction, the fixed glue spraying component 10, the upper glue spraying component 9 and the lower glue spraying component 8 are all connected to the glue spraying system, and the glue spraying system is a common technology in composite plate processing, and will not be described in detail. An infrared counter-radiation sensor is provided on the transfer conveyor 3, and its transmitter and receiver are respectively installed on the edges of both sides of the transfer conveyor 3. The infrared counter-radiation sensor is connected to the driving motor of the transfer conveyor 3 through the PLC control system. When the infrared counter-radiation sensor detects that the lower plate on the transfer conveyor 3 moves to the specified position, the transfer conveyor 3 can be controlled to be stationary, thereby positioning the lower plate;

[0046] When in use, the lower plate is placed on the lower plate conveyor 5, the core plate is placed on the core plate conveyor 6, the upper plate is placed on the upper plate conveyor 7, and the lower plate conveyor 5, the core plate conveyor 6, the upper plate conveyor 7 and the transfer conveyor 3 are started. By setting the timing of placing the plates or the conveying speed of each conveyor, the lower plate, the core plate and the upper plate can be controlled to arrive at the ends of each conveyor in sequence. When the lower plate passes through the lower glue spraying assembly 8, the lower glue spraying assembly 8 is started to spray glue on the top surface of the lower plate. When the upper plate passes through the upper glue spraying assembly 9, the upper glue spraying assembly 9 is started to spray glue partially on the bottom surface of the upper plate.

[0047] The lower plate that first reaches the end of the lower plate conveyor 5 is directly conveyed to the transfer conveyor 3 and stops at the specified position, and then the grabbing mechanism 4 is started. The grabbing mechanism 4 drives the substrate 41 to move to the core plate conveyor 6, clamps the core plate on the core plate conveyor 6 through the clamp 43, and then places the core plate on the top of the lower plate on the transfer conveyor 3. Then the grabbing mechanism 4 continues to control the substrate 41 to move to the upper plate conveyor 7, fixes the upper plate by suction through the suction cup 42, and then drives the upper plate to move along the conveying direction of the upper plate conveyor 7. When the upper plate passes through the fixed glue spraying assembly 10, the fixed glue spraying assembly 10 sprays glue on the glue-free area at the bottom of the upper plate, and then the grabbing mechanism 4 places the glue-sprayed upper plate on the top of the core plate, thereby realizing the stacking of three plates. Finally, the core plate conveyor 6 is operated again to convey the stacked composite plates to the inside of the compounding machine body 1 to realize compounding;

[0048] The lower plate, core plate and upper plate are moved to the side of the compound machine in sequence through the lower plate conveyor 5, the core plate conveyor 6 and the upper plate conveyor 7, wherein the lower plate is sprayed with glue by the lower spray glue assembly 8 during the conveying process, and then conveyed to the transfer conveyor 3, and the upper plate is sprayed with glue twice by the upper spray glue assembly 9 and the fixed spray glue assembly 10, and the core plate and the upper plate are grasped and stacked on the lower plate in turn by the grasping assembly, thereby realizing the automated stacking preparation work before the compounding work, and the stacked composite plates are then compounded by the compounding machine body 1, which is more efficient and labor-saving than manual operation, and has high stacking accuracy and small error compared to manual operation, thereby improving the quality of the compounded product.

[0049] Further, see Figure 3 The lower glue spraying assembly 8 is fixed on the lower plate conveyor 5, and the upper glue spraying assembly 9 is fixed on the core plate conveyor 6. The lower glue spraying assembly 8 and the upper glue spraying assembly 9 have the same structure and both include a first slide 81. Both ends of the first slide 81 are fixedly connected with legs 82. A first slide seat 83 is installed on the first slide 81, and a first glue spraying gun 84 is fixed on the first slide seat 83.

[0050] Among them, the legs 82 on the lower glue spraying assembly 8 are fixed to the edge of the lower plate conveyor 5, the legs 82 on the upper glue spraying assembly 9 are fixed to the edge of the core plate conveyor 6, the first slide 81 is set as an electric slide, and the moving direction of the first slide 83 is perpendicular to the conveying direction of each plate;

[0051] When in use, the first slide 81 operates, driving the first slide seat 83 to reciprocate along the first slide 81, thereby driving the first glue spraying gun 84 to reciprocate, and the first glue spraying gun 84 evenly sprays glue on the surface of the conveyed plate;

[0052] By providing the lower glue spraying assembly 8 and the upper glue spraying assembly 9 with the same structure, it is advantageous to spray glue on the top surface of the lower plate and the bottom surface of part of the upper plate so as to connect and compound with the core plate.

[0053] Further, see Figure 2-Figure 4, the upper plate conveyor 7 is provided with two, the two upper plate conveyors 7 are arranged opposite to each other, the upper plate conveyor 7 includes a shell 71, a plurality of evenly distributed driving shafts 72 are rotatably connected in the shell 71, one end of the driving shaft 72 penetrates the outside of the shell 71 and is fixedly connected to a roller 73, the driving shaft 72 is located inside the shell 71 and is fixed with a driving gear 74 at one end, and a plurality of evenly distributed driven shafts 75 are rotatably connected in the shell 71, the driven shaft 75 is located between adjacent driving shafts 72, a driven gear 76 is fixedly connected to the driven shaft 75, and the driven gear 76 is simultaneously meshed with the adjacent driving gears 74 on both sides, a first motor 77 is fixedly connected to the outer wall of the shell 71, and the output shaft of the first motor 77 is fixedly connected to one of the driving shafts 72, the fixed glue spraying assembly 10 includes a mounting plate 101, the mounting plate 101 is fixed to the end of the shell 71, and a second glue spraying gun 102 is fixedly connected to the mounting plate 101;

[0054] The rollers 73 on the two upper plate conveyors 7 are arranged in opposite directions and horizontally, a gap is arranged between the two groups of rollers 73, the position of the second glue gun 102 corresponds to the position of the rollers 73, and the spraying range of the second glue gun 102 is also set within the length range of the rollers 73. When in use, the upper plate is placed on the two groups of rollers 73, the edge of the upper plate is supported by the two groups of rollers 73, the first motor 77 is started, and the first motor 77 drives the driving shaft 72 to rotate when it is running, and then drives the driving gear 74 and the rollers 73 to rotate, and the main When the moving gear 74 rotates, it drives the driven gear 76 to rotate, thereby driving the adjacent driving gear 74 to rotate, thereby simultaneously driving all the driving shafts 72 and the rollers 73 on the driving shafts 72 to rotate, thereby pushing the upper plate to move, thereby realizing the horizontal transportation of the upper plate. When the upper plate passes through the upper glue spraying assembly 9, part of the bottom area is sprayed with glue, and the part of the bottom of the upper plate that contacts the rollers 73 is not sprayed with glue. When the upper plate moves under the action of the grabbing mechanism 4 and passes through the fixed glue spraying assembly 10, the second glue spraying gun 102 sprays glue on the glue-free area at the bottom of the upper plate;

[0055] By using two sets of upper plate conveyors 7 arranged opposite to each other, the edge of the upper plate is supported by rollers 73 and the upper plate is driven to move, which is conducive to the transportation of the upper plate. At the same time, an upper glue spraying component 9 and a fixed glue spraying component 10 are arranged to spray glue on the bottom of the upper plate twice, which can ensure that the bottom surface of the lower plate is fully adhered to glue and prevent the rollers 73 on the upper plate conveyor 7 from contacting the glue.

[0056] Further, see Figure 4-Figure 7The grabbing mechanism 4 also includes a bracket 44, on which a horizontally arranged second slide 45 is fixed, on which a second slide seat 46 is installed, on which a vertically arranged cylinder 47 is fixed, and an output end of the cylinder 47 is fixedly connected to a base plate 41, on which two through grooves 48 are provided on the surface of the base plate 41, and the clamp 43 is provided with two and respectively located in the two through grooves 48, and the clamp 43 includes a slide rail 431, and two symmetrically distributed sliders 432 are slidably connected inside the slide rail 431, and a clamping rod 433 is fixedly connected to the bottom of the two sliders 432, and a bidirectional screw 434 is also provided inside the slide rail 431, and the bidirectional screw 434 passes through the two sliders 432 and is threadedly connected to the two sliders 432, and both ends of the bidirectional screw 434 are rotatably connected to the slide rail 431, and a second bevel gear 435 is fixed to the middle of the bidirectional screw 434, and the A second motor 436 is fixed to the top of the slide rail 431, and the output shaft of the second motor 436 is movably plugged into the inside of the slide rail 431 and fixed with a first bevel gear 437, which is meshed with the second bevel gear 435. An air pipe 49 is fixedly connected to the top of the base plate 41, and the air pipe 49 is connected to the suction cup 42. A vertically arranged piston sleeve 491 is also fixedly connected to the air pipe 49, and the piston sleeve 491 is communicated with the air pipe 49. A piston 492 is arranged in the piston sleeve 491, and a push spring 493 is fixedly connected between the top of the piston 492 and the inner top wall of the piston sleeve 491. A vertical rod 494 is fixedly connected to the bottom of the piston 492, and the bottom end of the vertical rod 494 is fixedly connected to the slide rail 431. A guide rod 495 is also fixedly connected to the top of the slide rail 431, and a collar 496 is movably sleeved on the guide rod 495, and the collar 496 is fixedly connected to the base plate 41.

[0057] Among them, the second slide 45 is set as an electric slide, one end of the second slide 45 extends to the top of the upper plate conveyor 7, and the other end of the second slide 45 extends to the top of the compound machine body 1. The sliding direction of the second slide 46 is consistent with the conveying direction of each conveyor. The width of the base plate 41 is smaller than the width of the gap between the two groups of upper plate conveyors 7. The surface of the bidirectional screw 434 is provided with two groups of symmetrical and oppositely rotating threads, and the two groups of threads are matched with the two sliders 432 respectively. The air pipe 49 is externally connected to the vacuum system so that the suction cup 42 has an adsorption function. The guide rod 495 and the collar 496 are set as two groups and are respectively distributed at both ends of the slide rail 431. The clamping rod 433 is vertically arranged. In the initial state, the push spring 493 is at its original length, and the height of the clamping rod 433 is lower than the height of the suction cup 42.

[0058] When in use, the second slide 45 drives the second slide seat 46 to slide after operation, driving the cylinder 47 and the base plate 41 to move above the core plate, and then the cylinder 47 operates to drive the base plate 41 to move downward. When the base plate 41 moves downward, it drives the clamping rod 433 on the clamp 43 to move downward. When the clamping rod 433 is inserted into the core plate, the second motor 436 is started. The operation of the second motor 436 drives the first bevel gear 437 to rotate. When the first bevel gear 437 rotates, it drives the second bevel gear 435 to rotate, and then drives the bidirectional screw 434 to rotate. When the bidirectional screw 434 rotates, it also drives the two sliders 432 to slide, and then drives the two clamping rods 433 to move at the same time, clamping and fixing the core plate, and then the second slide 45 and the cylinder 47 are started again, and the core plate can be moved and placed below. The upper plate is then moved to the core plate surface by the second slide 45 and the cylinder 47. The upper plate is then moved to the core plate surface by the second slide 45 and the cylinder 47.

[0059] By setting up a grasping mechanism 4, the core plate is fixed by the clamp 43 set on the base plate 41, and then the core plate is moved by the second slide 45 and the cylinder 47. Similarly, the upper plate is fixed by the suction cup 42 set on the base plate 41, and then the upper plate is moved by the second slide 45 and the cylinder 47. This is conducive to the stacking of the upper and lower plates. In addition, by setting up a piston sleeve 491, a piston 492 and a push spring 493 connected to the air pipe 49, when the suction cup 42 is running, the negative pressure in the air pipe 49 is used to drive the clamp 43 to move, thereby avoiding the clamp 43 interfering with the adsorption work of the suction cup 42.

[0060] Further, see Figure 4 The bottom of the shell 71 is slidably connected to the mounting frame 2, and the shell 71 is also fixedly connected to a base block 78. A stud 79 is provided on the mounting frame 2. The stud 79 penetrates the mounting frame 2 and is threadedly connected to the mounting frame 2. One end of the stud 79 is rotatably connected to the base block 78;

[0061] The sliding direction of the housing 71 and the mounting frame 2 is perpendicular to the conveying direction of the upper plate conveyor, and the axis of the stud 79 is also perpendicular to the conveying direction of the upper plate conveyor. When in use, the housing 71 can be pushed to slide by rotating the stud 79, so that the entire upper plate conveyor moves. At the same time, adjusting the position of the two upper plate conveyors can change the spacing between the two sets of rollers 73, and can also adjust the position of the fixed glue spraying assembly 10.

[0062] The positions of the two upper plate conveyors and the two fixed glue spraying assemblies 10 can be adjusted by rotating the studs 79, which is helpful for adapting to upper plates of different specifications.

[0063] Further, see Figure 1 and Figure 8 The feeding end of the compound machine body 1 is provided with a press edge assembly 11, and the press edge assembly 11 includes two support plates 111 fixed on the compound machine body 1, and a movable rod 112 is provided between the two support plates 111, and both ends of the movable rod 112 are respectively rotatably connected to the two support plates 111, and the end of the movable rod 112 is fixedly connected to a fourth gear 113, and a third motor 110 is fixed on one of the support plates 111, and a third gear 114 is fixed to the output shaft of the third motor 110, and the third gear 114 is meshed with the fourth gear 113, a roller frame 115 is provided on the movable rod 112, a pressure roller 116 is rotatably connected to the roller frame 115, an insertion rod 117 is fixedly connected to the roller frame 115, an end of the insertion rod 117 away from the roller frame 115 is movably plugged with the movable rod 112, an end of the insertion rod 117 away from the roller frame 115 is fixedly connected to an end block 118, a return spring 119 is fixedly connected between the end block 118 and the movable rod 112, and the return spring 119 is sleeved on the outside of the insertion rod 117;

[0064] In the initial state, the end of the insert rod 117 where the roller frame 115 is located is vertically upward, the movable rod 112 is located directly above the feeding end of the compound machine body 1, the insert rod 117, the breaking block and the return spring 119 are preferably arranged in two groups, and the diameter of the end block 118 is larger than the diameter of the insert rod 117;

[0065] When in use, when the lower plate, the core plate and the upper plate are stacked on the transfer conveyor 3 to form a composite plate, the third motor 110 is started. When the third motor 110 is running, it drives the third gear 114 to rotate. The rotation of the third gear 114 drives the fourth gear 113 to rotate. When the fourth gear 113 rotates, it drives the movable rod 112 to rotate. When the movable rod 112 rotates, it drives the insertion rod 117 to swing, and then drives the roller frame 115 and the pressure roller 116 at the end of the insertion rod 117 to move, so that the pressure roller 116 just presses on the top edge of the composite plate near one end of the compound machine body 1. Then, when the transfer conveyor 3 is running, the composite plate is driven to move toward the inside of the compound machine body 1. At the same time, the insertion rod 117 and the pressure roller 116 continue to move with the rotation of the movable rod 112, and the pressure roller 116 always keeps in contact with the composite plate. At this time, the movement of the insertion rod 117 includes the rotation around the movable rod 112 and the sliding relative to the movable rod 112. The sliding of the insertion rod 117 can pull the reset spring 119 to stretch the reset spring 119. Finally, when the pressure roller 116 moves with the composite plate to the point where it is about to enter the interior of the composite machine body 1, the third motor 110 stops running. When the composite plate completely enters the interior of the composite machine body 1, the third motor 110 controls the third gear 114 to rotate in the opposite direction, and similarly, it can drive the pressure roller 116 to reset.

[0066] By providing the edge pressing assembly 11, the pressure applied to the edge of the composite plate formed after stacking can be increased until the edge of the composite plate enters the interior of the composite machine body 1. This can effectively prevent the edge from curling due to the internal stress of the upper plate, thereby causing composite failure or reduced composite quality, thereby improving the stability and fault tolerance of the composite equipment during operation.

[0067] Working principle: When in use, put the lower plate on the lower plate conveyor 5, put the core plate on the core plate conveyor 6, put the upper plate on the upper plate conveyor 7, and start the lower plate conveyor 5, the core plate conveyor 6, the transfer conveyor 3 and the two sets of upper plate conveyors 7. When the upper plate conveyor 7 is running, the first motor 77 is started. When the first motor 77 is running, it drives the driving shaft 72 to rotate, and then drives the driving gear 74 and the roller 73 to rotate. When the driving gear 74 rotates, it drives the driven gear 76 to rotate, and then drives the adjacent driving gear 74 and the roller 73 to rotate. The gear 74 rotates, thereby simultaneously driving all the drive shafts 72 and the rollers 73 on the drive shafts 72 to rotate, thereby pushing the upper plate to move, thereby realizing horizontal conveying of the upper plate. By setting the timing of placing the plate or the conveying speed of each conveyor, the lower plate, the core plate and the upper plate can be controlled to arrive at the ends of each conveyor in sequence. When the lower plate passes through the lower glue spraying assembly 8, the lower glue spraying assembly 8 is started to spray glue on the top surface of the lower plate. When the upper plate passes through the upper glue spraying assembly 9, the upper glue spraying assembly 9 is started to spray glue on a part of the bottom surface of the upper plate.

[0068] The lower plate that first arrives at the end of the lower plate conveyor 5 is directly conveyed to the transfer conveyor 3 and remains stationary at the designated position. At this time, the second slide 45 and the cylinder 47 are started. After the second slide 45 is operated, the second slide 46 is driven to slide, driving the cylinder 47 and the base plate 41 to move above the core plate. When the cylinder 47 is operated, the base plate 41 is driven to move downward. When the base plate 41 moves downward, the clamping rod 433 on the clamp 43 is driven to move downward. When the clamping rod 433 is inserted into the core plate, the second motor 436 is started. The operation of the second motor 436 drives the first bevel gear 437 to rotate. When the first bevel gear 437 rotates, it drives the second bevel gear 435 to rotate, and then drives the bidirectional screw 434 to rotate. When the bidirectional screw 434 rotates, it simultaneously drives the two sliders 432 to slide, and then drives the two clamping rods 433 to move at the same time, clamping and fixing the core plate. Similarly, the core plate can be moved and placed on the lower plate by the second slide 45 and the cylinder 47 again.

[0069] The second slide 45 and the cylinder 47 are operated again to place the substrate 41 on the upper plate. When the clamp rod 433 on the clamp 43 contacts the surface of the upper plate, it remains stationary and compresses the push spring 493. At the same time, the adsorption function of the suction cup 42 is activated. The suction cup 42 generates suction when it is in operation, fixes the upper plate when it contacts the upper plate, and there is negative pressure inside the air pipe 49 when the suction cup 42 is in operation. The negative pressure causes the piston 492 to move, further compressing the compressed spring, and the movement of the piston 492 also drives the vertical rod 494 and the entire clamp 43 to move, thereby The clamping rod 433 on the clamp 43 is separated from the surface of the upper plate, and then the upper plate is driven to move along the upper plate conveyor 7 by the second slide 45 and the cylinder 47. When the upper plate passes through the fixed glue spraying assembly 10, the fixed glue spraying assembly 10 is operated, and the glue-free area at the bottom of the upper plate is sprayed with glue by the second glue spraying gun 102. Finally, the upper plate is driven to move and placed on the top surface of the core plate by the second slide 45 and the cylinder 47. The stacked lower plate, core plate and upper plate form a composite plate, and the transfer conveyor 3 is started to convey the composite plate to the composite machine body 1, thereby realizing the composite work;

[0070] The lower plate, core plate and upper plate are moved to the side of the compound machine in sequence through the lower plate conveyor 5, the core plate conveyor 6 and the upper plate conveyor 7, wherein the lower plate is sprayed with glue by the lower spray glue assembly 8 during the conveying process, and then conveyed to the transfer conveyor 3, and the upper plate is sprayed with glue twice by the upper spray glue assembly 9 and the fixed spray glue assembly 10, and the core plate and the upper plate are grasped and stacked on the lower plate in turn by the grasping assembly, thereby realizing the automated stacking preparation work before the compounding work, and cooperating with the compounding machine body 1, it can realize the continuous compounding work of the composite plate material, which is more efficient and labor-saving than manual operation, and has high stacking accuracy and small error compared with manual operation, thereby improving the quality of the compounded product.
