[0023] Laminated insulating paperboard (hereinafter referred to as laminated paperboard) is a key basic material in the fields of power equipment, electronic products and aerospace. Its performance is directly related to the operational reliability and service life of the end products. At present, the manufacturing process of laminated paperboard still follows the traditional production mode. Its core processes, such as adhesive coating, paperboard layup and hot pressing curing, are all completed manually. This production mode is relatively mature, workers are highly accepting of it, and it helps to save on labor training costs.

[0024] However, the applicant's observations and research revealed certain systemic flaws in the traditional production model. Specifically, differences in worker skills lead to significant unevenness in adhesive layer thickness. Furthermore, the manual placement of the glued cardboard onto the underlying cardboard during the lamination process makes precise control difficult, compromising the quality of the laminated cardboard. Simultaneously, the quality of laminated cardboard produced by each batch is inconsistent, with significant differences in quality stability between batches. Moreover, production time is difficult to manage, hindering efficiency. As insulation components evolve towards multi-functionality, high performance, and complex structures, this phenomenon indicates that the traditional manufacturing model is insufficient to meet the high-level requirements of modern industry for the quality and consistency of insulation components.

[0025] In view of this, the present invention proposes a laminated paperboard processing equipment to solve or at least alleviate the above-mentioned problems.

[0026] Please see Figures 1 to 5In one embodiment of this utility model, the laminated paperboard processing equipment includes a conveying device 1, a gluing device 2, and a laying device 3. The conveying device 1 includes a loading platform 11 and a transport component; the gluing device 2 includes a support 21 and a drive roller 22, a gluing roller 23, and a glue tank 24 mounted on the support 21, pointing from the bottom to the top of the support 21. The glue tank 24, the gluing roller 23, and the drive roller 22 are arranged alternately and parallel to each other. The glue tank 24 is used to hold glue liquid, and at least a portion of the gluing roller 23 is immersed in the glue liquid. A feed inlet 25 is formed between the gluing roller 23 and the drive roller 22. The transport component is used to feed the paperboard into the feed inlet 25; the laying device 3 includes a laying platform 31 and a positioning structure 32. The loading platform 11 and the laying platform 31 are respectively located on both sides of the feed inlet 25. The positioning structure 32 includes a positioning post 3224, which is used to abut against the edge of the paperboard.

[0027] Specifically, the handling component includes either a handling robot or a vacuum suction cup lifting device. After the cardboard is conveyed to the loading table 11, the handling component can feed one end of the cardboard into the feed port 25. In the production process of laminated paperboard, the laying table 31 is used to receive the glued paperboard. As the gluing roller 23 and the drive roller 22 rotate, the paperboard moves continuously towards the laying table 31. The positioning post 3224 is used to limit the movement direction of the paperboard and prevent the paperboard from deviating. After the paperboard is glued, it needs to be bonded to the base plate pre-placed on the laying table 31. The edge of the base plate is also aligned with the base of the positioning post 3224 to prevent the base plate from moving under the action of the paperboard. The base plate referred to here is the bottom paperboard, which can be the bottommost paperboard in the laminated paperboard or a multi-layer paperboard formed by bonding multiple layers of paperboard. The lay-up process refers to the process of applying glue to the bottom of the paperboard (or gluing) and laying it on the base plate and bonding it to the base plate.

[0028] According to the technical solution of this embodiment, the steps of the laminated paperboard processing equipment for processing laminated paperboard are as follows: the base plate is laid on the laying table 31, so that the positioning post 3224 abuts against the base plate; the laminated paperboard processing equipment is started, and the loading table 11 receives the paperboard that needs to be coated with glue; the conveying component feeds the paperboard into the feed inlet 25, so that the paperboard moves towards the laying table 31 under the action of the gluing roller 23 and the drive roller 22; during the movement of the paperboard, the gluing roller 23 drives the glue in the glue tank 24 to coat the bottom surface of the paperboard; during the movement of the paperboard towards the laying table 31, the conveying component can adsorb or clamp the paperboard and guide the paperboard to gradually descend in height to avoid the paperboard from curling; as the gluing roller 23 and the drive roller 22 rotate, the bottom of the paperboard is completely coated with glue, at which point the edge of the paperboard abuts against the positioning post 3224, and the conveying component releases the paperboard so that the paperboard is completely attached to the base plate.

[0029] According to the technical solution of this embodiment, during the processing of laminated paperboard, a base plate is pre-laid on the laying table 31. The paperboard on the loading table 11 can be automatically transported to the feed inlet 25 under the action of the conveying components. The gluing roller 23 and the transmission roller 22 rotate to drive the paperboard to continuously move towards the laying table 31. During this process, the gluing roller 23 continuously coats the bottom surface of the paperboard with the glue in the glue tank 24, realizing an automatic gluing process and improving the uniformity of the glue layer distribution. After the paperboard passes through the feed inlet 25, it can accurately align with the base plate under the limiting action of the positioning column 3224, preventing the paperboard from shifting relative to the base plate. In this way, automatic gluing and automatic layering of laminated paperboard are realized, which is beneficial to improving the processing efficiency of laminated paperboard, and automated processing is beneficial to improving the consistency of product quality.

[0030] In one embodiment of this utility model, please refer to Figures 6 to 8 The positioning structure 32 also includes a base frame 321 and a positioning component 322. The base frame 321 is mounted on the material spreading platform 31 and is used to support the positioning component 322. The positioning component 322 includes a first lead screw 3221, a second lead screw 3222, a connecting block 3223, and a positioning post 3224. The direction from the loading platform 11 to the material spreading platform 31 is defined as the first horizontal direction Y (see [reference]). Figure 1 or Figure 6 (The direction indicated by the middle arrow Y), the extension direction of the drive roller 22 is the second horizontal direction X (see [reference]). Figure 1 or Figure 6 (As indicated by the arrow X), the first horizontal direction Y and the second horizontal direction X are perpendicular to each other; then, the first lead screw 3221 is rotatably mounted on the base frame 321 along the first horizontal direction Y, the connecting block 3223 is sleeved on the first lead screw 3221 and threadedly connected to the first lead screw 3221, the second lead screw 3222 is slidably connected to the base frame 321 along the second horizontal direction X, the connecting block 3223 is sleeved on the second lead screw 3222 and rotatably connected to the second lead screw 3222, and the positioning post 3224 is sleeved on the second lead screw 3222 and threadedly connected to the second lead screw 3222.

[0031] Specifically, in this embodiment, the bottom end of the positioning post 3224 abuts against the top surface of the material spreading platform 31 to limit the position of the base plate. When the first lead screw 3221 rotates, it can drive the connecting block 3223 to move along the first horizontal direction Y, thereby causing the connecting block 3223 to drive the second lead screw 3222 to move along the first horizontal direction Y. The base frame 321 is used to support the second lead screw 3222 and prevent the end of the second lead screw 3222 from drooping towards the ground due to gravity. Specifically, a slider rotatably connected to the second lead screw 3222 can be sleeved on the second lead screw 3222, and the slider is slidably connected to the base frame 321, so that the slider can slide on the base frame 321 and support the end of the second lead screw 3222 to prevent drooping. Both ends of the first lead screw 3221 can be directly rotatably connected to the base frame 321, and the base frame 321 located on the side of the feed inlet 25 does not interfere with the feed inlet 25. The specific structure of the base frame 321 can be adjusted according to the needs of those skilled in the art. In this embodiment, rotating the first lead screw 3221 moves the positioning post 3224 along the first horizontal direction Y, thereby adjusting the position of the positioning post 3224 along the first horizontal direction Y. After the first lead screw 3221 is adjusted, rotating the second lead screw 3222 moves the positioning post 3224 along the second horizontal direction X. This configuration allows the position of the positioning post 3224 to be adaptively adjusted according to the dimensions of the base plate and the cardboard, enabling the laminated cardboard processing equipment to handle the processing of cardboard of various sizes.

[0032] Further, please refer to Figure 6 The positioning component 322 includes two positioning pins 3224, both of which are threadedly connected to the second lead screw 3222. Rotating the second lead screw 3222 causes the two positioning pins 3224 to move towards each other or away from each other. Specifically, in one embodiment, the positioning pins 3224 are provided with threaded holes, and the threads inside the threaded holes of the two positioning pins 3224 are in opposite directions, thereby enabling the function of rotating the second lead screw 3222 to cause the two positioning pins 3224 to move towards each other or away from each other.

[0033] In another embodiment, the threads of the second lead screws 3222 on both sides of the connecting block 3223 are opposite, and the threads of the threaded holes of the positioning pins 3224 are in the same direction. This structure can also realize the function of making the two positioning pins 3224 move towards each other or away from each other.

[0034] This design allows the gap between the two positioning posts 3224 to be adaptively adjusted according to the width of the cardboard and the base plate, enabling the cardboard and the base plate to precisely abut against the positioning posts 3224 and preventing displacement of the cardboard in the second horizontal direction X during the bonding process with the base plate.

[0035] It should be noted that the positioning post 3224 is cylindrical in shape. The cylindrical positioning post 3224 can play a certain guiding role on the cardboard through its arc-shaped outer periphery, so as to correct the posture of the cardboard as it moves toward the feeding table 31.

[0036] Furthermore, please refer to Figures 6 to 8 In one embodiment of this utility model, the number of positioning components 322 is two sets, and the two sets of positioning components 322 are arranged alternately. Specifically, in this embodiment, the number of first lead screws 3221, second lead screws 3222, and connecting blocks 3223 are all two, and correspondingly, the number of positioning posts 3224 is four. The two first lead screws 3221 are arranged alternately along the vertical direction Z (see the direction indicated by arrow Z in the figure), and the two second lead screws 3222 are arranged in layers along the vertical direction Z and alternately along the first horizontal direction Y. Through this arrangement, one set of positioning posts 3224 can be set at the end of the bottom plate away from the feed port 25, preventing the cardboard from applying a pushing force in the first horizontal direction Y to the bottom plate and causing the bottom plate to move in the first horizontal direction Y. The other set of positioning posts 3224 can be set on both sides of the bottom plate along the second horizontal direction X, so that the positioning posts 3224 can restrict the movement of the bottom plate and the cardboard in the second horizontal direction X. The technical solution provided in this embodiment can further improve the bonding accuracy between the cardboard and the baseboard, so as to minimize the cutting area of ​​the laminated cardboard edge and help control the material cost of producing laminated cardboard.

[0037] In one embodiment of this utility model, please refer to Figure 7 and Figure 8 The positioning assembly 322 also includes a crank handle 3225, with the crank handle 3225 installed at the ends of both the first lead screw 3221 and the second lead screw 3222. The crank handle 3225 allows the worker to manually crank the first lead screw 3221 or the second lead screw 3222. This allows the worker to directly hold the crank handle 3225 and quickly rotate the corresponding lead screw without tools, achieving positioning adjustment of the positioning column 3224 in the first horizontal direction Y and the second horizontal direction X. Manual drive eliminates the need for an additional power source and control system, resulting in a simple structure, low cost, low failure rate, and the ability to be started and stopped at any time, facilitating flexible operation in small-batch, multi-specification applications.

[0038] In one embodiment of this utility model, please refer to Figure 4 and Figure 5The support 21 includes a first sub-frame 211 and a second sub-frame 212 spaced apart. The glue tank 24, the glue roller 23, and the drive roller 22 are all connected at both ends to the first sub-frame 211 and the second sub-frame 212, respectively. The glue roller 23 and the drive roller 22 are rotatably connected to the first sub-frame 211 and the second sub-frame 212. This arrangement rotatably supports both ends of the glue tank 24, the glue roller 23, and the drive roller 22 on the spaced first sub-frame 211 and the second sub-frame 212, forming a simply supported structure with symmetrical ends. This significantly reduces the radial runout of the rollers when rotating at high speed, resulting in more uniform glue coating. Furthermore, the open space between the two sub-frames facilitates observation of the glue tank 24 level, rapid glue replenishment, and cleaning of residual glue, further improving the stability and efficiency of continuous production of laminated paperboard.

[0039] In one embodiment of this utility model, please refer to Figures 1 to 5 The bracket 21 also includes a support frame (not shown), which is connected to the first sub-frame 211 and the second sub-frame 212 respectively. The support frame is located on the side of the glue tank 24 away from the glue roller 23. The glue applicator 2 also includes at least two cantilever rods 26. One end of the cantilever rod 26 is connected to the support frame, and the other end of the cantilever rod 26 is a cantilever end. The cantilever rod 26 extends along the direction from the loading platform 11 to the spreading platform 31. The cantilever rod 26 is used to undergo elastic deformation after receiving at least part of the cardboard. With this arrangement, at least two cantilever rods 26 can form a stable elastic support frame. When the cardboard coated with glue moves towards the spreading platform, the cantilever rod 26 can directly support the cardboard. Under the action of the cardboard's gravity, the cantilever end undergoes elastic downward deformation, allowing the cardboard to slowly slide down along the first horizontal direction Y until the cardboard slides to the position where it abuts against the positioning post 3224. During this process, the buffer ramp formed by the cantilever 26 prevents the cardboard from drooping directly towards the laying board, thus avoiding misalignment between the cardboard and the base plate. Simultaneously, the conveying components guide and support the cardboard as it slides.

[0040] Furthermore, the gluing device 2 also includes a drive assembly (not shown), which is used to move the cantilever rods 26 closer together or further apart. Specifically, in one embodiment, the fixed end of the cantilever rod 26 is connected to a slider, the slider has a threaded hole, and the support frame has a slide rail for the slider to slide. The slider is driven to slide by a screw motor, thereby causing the cantilever rod 26 to translate along the second horizontal direction X. There are two sets of cantilever rods 26, each set having at least one cantilever rod 26, and the two sets of cantilever rods 26 move towards each other or away from each other. After the cardboard is completely coated with glue, the cardboard falls completely onto the cantilever rods 26. At this time, the screw motor drives the slider to slide, causing the slider to drive the cantilever rods 26 to slide to both sides of the cardboard, so that the cardboard can fall completely and bond with the base plate.

[0041] In another embodiment, the fixed end of the cantilever 26 is connected to the slider, and a slide rail is provided on the support frame for the slider to slide. The slider is driven to slide by a telescopic cylinder or electric cylinder, thereby causing the cantilever 26 to translate along the second horizontal direction X. This also enables the two sets of cantilever 26 to move closer or further apart. The specific structure of the drive assembly can be determined according to the actual needs of those skilled in the art.

[0042] In one embodiment of this utility model, please refer to Figure 1 The laminated paperboard processing equipment also includes a protective cover 4 and an exhaust device. The protective cover 4 forms a working chamber 41, which covers the gluing device 2 and the laying device 3. The gluing device 2 and at least part of the laying device 3 are housed in the working chamber 41. The exhaust device is connected to the working chamber 41 and is used to create a negative pressure inside the working chamber 41. The exhaust device includes a blower and an exhaust pipe connected to the blower. The blower is used to draw the irritating gas volatilized from the adhesive in the working chamber 41 into the exhaust pipe, and the exhaust pipe is used to discharge the gas into the waste gas treatment system. The exhaust device needs to be continuously turned on during the lamination process to prevent the irritating gas from escaping. The protective cover 4 does not need to be strictly sealed; it has an opening on the side facing the feeding plate to allow the paperboard to enter the feed inlet 25. The protective cover 4 also has an openable and closable protective door at the end away from the feeding table 11. After the paperboard and the base plate are bonded, the worker opens the protective door and pulls out the laying table 31 to transport the paperboard and the base plate to the hot press for the hot pressing process. Then, another base plate is placed into the material spreading platform 31, and the material spreading platform 31 is pushed into the working chamber 41 for the next round of material spreading. The material spreading platform 31 is provided with a sliding fit between itself and the ground, such as the fit between the slide rail and the slider, so as to facilitate the pulling out and pushing in of the material spreading platform 31, improve work efficiency, and at the same time prevent the material spreading platform 31 from shifting.

[0043] In one embodiment of this utility model, the loading platform 11 is as follows: Figure 9 As shown, a conveyor chain (not shown) is installed on the top surface of the loading platform 11. The conveyor chain is used to move the cardboard horizontally. The conveyor chain is connected to an external transmission system to receive the cardboard and move it horizontally. In this way, the automation level of the laminated cardboard processing equipment can be further improved, avoiding the problem of low operating efficiency caused by manual handling of cardboard.

[0044] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
