Abstract

This utility model discloses a hot-press forming device for aluminum composite panel (ACP) production, relating to the field of ACP production technology. The utility model includes a support frame, with an upper pressure roller installed on the right side of the inner side of the support frame. This utility model utilizes the rotational cooperation between a rotating rod and a base to allow the correction platform to swing freely. When the ACP is conveyed off-center, it pushes the guide roller to rotate the correction platform. The swinging support rod rotates synchronously with the rotating rod, stretching or compressing the ring spring.

Description

Technical Field

[0001] This utility model belongs to the field of aluminum composite panel production technology, and in particular relates to a hot pressing forming device for aluminum composite panel production. Background Technology

[0002] As a new type of composite decorative material, aluminum composite panels (ACPs) are widely used in various fields such as building exterior wall decoration, interior partitions, advertising signs, and furniture manufacturing due to their lightweight, high strength, fire and water resistance, corrosion resistance, convenient processing, and excellent decorative effect. Market demand continues to rise, and the requirements for production efficiency and product quality are also constantly increasing. Hot pressing is the core process in the production of ACPs. Its main function is to hot press aluminum foil, adhesive film, and plastic core board and other multi-layer substrates under specific temperature and pressure conditions to make the substrate layers tightly bonded, forming a composite board that combines the decorative properties of the aluminum layer and the toughness of the plastic layer. The processing effect of this process directly determines the key performance indicators of ACPs such as peel strength, surface flatness, and dimensional accuracy.

[0003] However, when hot pressing the plastic sheet, it is usually necessary to guide and feed it to ensure the molding quality. Since the plastic sheet itself is relatively soft, if it is fed by rigid guide, it will increase the risk of scratching and damage to the edge of the sheet and reduce the subsequent hot pressing quality. Therefore, a hot pressing device for aluminum-plastic sheet production is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a hot-press forming device for aluminum composite panel (ACP) production. The device utilizes the rotational cooperation between a rotating rod and a base to allow the correction platform to swing freely. When the ACP is conveyed off-center, it pushes the guide roller to rotate the correction platform. The swinging support rod rotates synchronously with the rotating rod and stretches or compresses the ring spring. The elastic tension of the ring spring forms a reset force, causing the correction platform to adaptively return to center, achieving real-time elastic correction of the ACP. This reduces the risk of edge scratches and damage caused by rigid limiting. Two diagonally arranged ring springs ensure more even force distribution during correction, improving correction accuracy. Simultaneously, protective components wrap and protect the ring springs, reducing the impact of dust and debris on spring elasticity and extending component lifespan. This solves the problem that, during hot pressing of ACP, to ensure molding quality, it is usually necessary to guide the material. However, since the ACP material is relatively soft, rigid guiding increases the risk of edge scratches and damage, reducing the subsequent hot-press forming quality.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a hot pressing forming device for aluminum composite panel production, comprising a support frame, an upper pressure roller mounted on the right inner side of the support frame, a lower pressure roller mounted below the upper pressure roller, an auxiliary roller mounted on the left inner side of the support frame, and a feeding mechanism mounted on the support frame. The feeding mechanism includes a correction assembly mounted on the support frame, comprising a base fixed to the bottom inner side of the support frame, a correction platform mounted above the base, a rotating rod fixedly connected to the bottom of the correction platform, the bottom of the rotating rod rotatably connected to the top of the base, and a swinging support rod fixedly connected to the outer surface of the rotating rod, with sliding connections at both ends of the swinging support rod. The positioning ring has two annular springs sleeved on its outer surface. Two fixed brackets are fixedly connected to the outer surface of the positioning ring. Mounting brackets are respectively provided on the front and back of the top of the correction platform. Guide rollers are respectively connected to corresponding sides of the two mounting brackets through pins. Protective parts are respectively installed on the outside of the two annular springs. The two annular springs are arranged diagonally. The two fixed brackets are arranged front and back. The bottom of the two fixed brackets is fixedly connected to the front and back of the top of the base, respectively. The ends of the two annular springs are fixedly connected to the sides of the two fixed brackets, respectively. The sides of the two annular springs away from the fixed brackets are fixedly connected to the sides of both ends of the swing support rod, respectively.

[0007] Furthermore, the feeding mechanism also includes an adjustment component, which is installed on the correction platform. The adjustment component includes a scale line on the top left side of the correction platform. The front and back sides of the top of the correction platform are respectively provided with sliding grooves, and sliders are slidably connected inside each of the two sliding grooves. The tops of the two sliders are respectively fixedly connected to the bottom of the mounting bracket. Indicator needles are respectively fixedly connected to the left side of the two mounting brackets, and the indicator needles are set corresponding to the scale line. Racks are fixedly connected to the corresponding sides of the two sliders. A gear is connected to the center of the correction platform through a pin. The outer surface of the gear meshes with the corresponding sides of the two racks. The top and bottom of the racks are slidably connected to the top and bottom of the inner wall of the correction platform.

[0008] Furthermore, a lead screw is rotatably connected to the front of the slider located on the front side. The lead screw passes through the correction platform and extends to the front side. The outer surface of the lead screw is threadedly connected to the front of the correction platform. A handwheel is provided on the front of the correction platform. The back of the handwheel is fixedly connected to the front of the lead screw. A pre-tension spring is sleeved on the outer surface of the lead screw. Both ends of the pre-tension spring are fixedly connected to limit plates. The back of the limit plate located on the back side is fixedly connected to the front of the correction platform. The front of the limit plate located on the front side is rotatably connected to the back of the handwheel. The pre-tension spring is initially in a relaxed state.

[0009] Furthermore, the two protective components include two protective sleeves, which are respectively fitted over the outside of the annular springs, and the two protective sleeves are configured in the same way as the components connected to the two annular springs.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model utilizes the rotational cooperation between the rotating rod and the base to allow the correction platform to swing freely. When the aluminum composite panel is conveyed off-center, it pushes the guide roller to drive the correction platform to rotate. The swinging support rod rotates synchronously with the rotating rod and stretches or compresses the ring spring. The elastic tension of the ring spring forms a reset force, driving the correction platform to adaptively return to center, realizing real-time elastic correction of the aluminum composite panel, reducing the risk of edge scratch damage caused by rigid limit. The two diagonally arranged ring springs make the correction force more uniform and improve the correction accuracy. At the same time, the protective component wraps and protects the ring spring, reducing the impact of dust and debris on the spring elasticity and extending the service life of the component. This correction structure requires no additional operation, adaptively responds to conveying offset, and improves the stability of feeding and conveying.

[0012] 2. This utility model utilizes the meshing of gears and two racks. When the handwheel is turned to drive the lead screw to rotate, the two sliders slide synchronously in opposite directions along the slide groove, realizing the synchronous adjustment of the distance between the two guide rollers. With the precise positioning of the scale line and indicator needle, it can quickly adapt to the production needs of aluminum composite panels of different widths. The adjustment steps are simple, improving the versatility of the equipment. At the same time, turning the handwheel compresses the pre-tension spring through the front limit plate. The pre-tension spring always applies a reverse thrust to the handwheel, keeping the thread surface of the lead screw in close contact, achieving the anti-rotation effect of the lead screw. This reduces the problem of lead screw rotation and guide distance deviation caused by vibration during long-term operation of the equipment, enhances the stability of the adjusted structure, reduces the frequency of maintenance, and improves production efficiency.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-6As shown, this utility model is a hot pressing forming device for aluminum composite panel production, including a support frame 111, an upper pressure roller 112 installed on the right side of the inner side of the support frame 111, a lower pressure roller 113 installed below the upper pressure roller 112, an auxiliary roller 114 installed on the left side of the inner side of the support frame 111, and a feeding mechanism 2 installed on the support frame 111. The feeding mechanism 2 includes a correction component 21, which is installed on the support frame 111. The correction component 21 includes a base 211 fixed to the bottom of the inner side of the support frame 111, and a correction platform 212 provided above the base 211. A rotating rod 213 is fixedly connected to the bottom, and the bottom of the rotating rod 213 is rotatably connected to the top of the base 211. A swing support rod 214 is fixedly connected to the outer surface of the rotating rod 213. Limiting rings 215 are slidably connected to both ends inside the swing support rod 214. Two annular springs 217 are sleeved on the outer surface of the limiting rings 215. Two fixed brackets 216 are fixedly connected to the outer surface of the limiting rings 215. Mounting brackets 219 are respectively provided on the front and back of the top of the correction platform 212. Guide rollers 210 are respectively connected to the corresponding sides of the two mounting brackets 219 through pins. Protective covers are respectively installed on the outside of the two annular springs 217. The system consists of two ring springs 217 diagonally positioned and two fixed supports 216 positioned front and rear. The bottoms of the two fixed supports 216 are fixedly connected to the front and back of the top of the base 211, respectively. The ends of the two ring springs 217 are fixedly connected to the sides of the two fixed supports 216, respectively. The sides of the two ring springs 217 away from the fixed supports 216 are fixedly connected to the sides of both ends of the swing support rod 214. The rotation of the rotating rod 213 in conjunction with the base 211 allows the correction platform 212 to swing freely. When the aluminum-plastic sheet deviates during conveying, it pushes the guide roller 210 to rotate the correction platform 212. 14 rotates synchronously with the rotating rod 213 and stretches or compresses the ring spring 217. The elastic tension of the ring spring 217 forms a reset force, driving the correction platform 212 to adaptively return to the center, realizing real-time elastic correction of the aluminum composite panel, reducing the risk of edge scratch damage caused by rigid limit. The two diagonally arranged ring springs 217 make the correction force more uniform and improve the correction accuracy. At the same time, the protective component wraps and protects the ring spring 217, reducing the impact of dust and debris on the spring elasticity and extending the service life of the component. This correction structure requires no additional operation, adaptively responds to conveyor offset, and improves the stability of feeding and conveying.

[0025] The feeding mechanism 2 also includes an adjustment component 22, which is installed on the correction platform 212. The adjustment component 22 includes a scale line 221 on the top left side of the correction platform 212. The front and back sides of the top of the correction platform 212 are respectively provided with slide grooves 222. Slider 226 is slidably connected inside each of the two slide grooves 222. The tops of the two sliders 226 are respectively fixedly connected to the bottom of the mounting bracket 219. Indicator needles 223 are respectively fixedly connected to the left side of the two mounting brackets 219. The indicator needles 223 are set corresponding to the scale line 221. The corresponding sides of the two sliders 226 are fixedly connected. A rack 224 is attached to the center of the correction platform 212 via a pin, and a gear 225 is connected to it. The outer surface of the gear 225 meshes with the corresponding side of the two racks 224. The top and bottom of the racks 224 are slidably connected to the top and bottom of the inner wall of the correction platform 212. A slider 226 located on the front is rotatably connected to a lead screw 227. The lead screw 227 passes through the correction platform 212 and extends to the front. The outer surface of the lead screw 227 is threaded to the front of the correction platform 212. A handwheel 228 is provided on the front of the correction platform 212, and the back of the handwheel 228 is fixed to the front of the lead screw 227. A preload spring 220 is fitted onto the outer surface of the lead screw 227. Limiting plates 229 are fixedly connected to both ends of the preload spring 220. The back of the limiting plate 229 on the back is fixedly connected to the front of the correction platform 212, while the front of the limiting plate 229 on the front is rotatably connected to the back of the handwheel 228. The preload spring 220 is initially in a relaxed state. Utilizing the meshing of gear 225 and two racks 224, when the handwheel 228 is rotated, causing the lead screw 227 to rotate, the two sliders 226 slide synchronously in opposite directions along the slide groove 222, achieving synchronous adjustment of the distance between the two guide rollers 210. The precise positioning of the scale line 221 and the indicator needle 223 allows for quick adaptation to the production needs of aluminum composite panels of different widths. The adjustment steps are simple, improving the versatility of the equipment. At the same time, rotating the handwheel 228 compresses the preload spring 220 through the front limit plate 229. The preload spring 220 always applies a reverse thrust to the handwheel 228, keeping the thread surface of the lead screw 227 in close contact. This achieves the anti-rotation effect of the lead screw 227, reducing the problem of lead screw 227 rotation and guide spacing deviation caused by vibration during long-term operation of the equipment. This enhances the stability of the structure after adjustment, reduces the frequency of maintenance, and improves production efficiency.

[0026] The two protective components include two protective rubber sleeves 218, which are respectively fitted onto the outside of the annular spring 217. The two protective rubber sleeves 218 are configured with the same components as the two annular springs 217.

[0027] A specific application of this embodiment is as follows: In use, the operator first adjusts the distance between the two guide rollers 210 according to the width of the aluminum composite panel to be processed. The handwheel 228 is turned to drive the lead screw 227 to rotate. The lead screw 227 drives the slider 226 on the front to slide along the slide groove 222. The slider 226 drives the rack 224 on the front to move. The rack 224 meshes with the gear 225 to drive the rack 224 and the slider 226 on the back to slide synchronously in opposite directions, thereby realizing the synchronous adjustment of the distance between the two guide rollers 210. During the adjustment process, the adjustment accuracy is controlled by the corresponding position of the indicator needle 223 and the scale line 221. After the adjustment is in place, the limiting piece 229 on the front squeezes the pre-tightening spring 220 during the rotation of the handwheel 228. The elastic thrust generated by the pre-tightening spring 220 always acts on the handwheel 228, so that the thread surface of the lead screw 227 is tightly fitted, reducing the situation of the lead screw 227 rotating on its own, and realizing the stable fixing of the distance.

[0028] When aluminum composite panels are being fed into the conveyor, the panels are conveyed by auxiliary rollers 114 to the space between two guide rollers 210. If a lateral deviation occurs during the conveying process, one guide roller 210 will be pushed to drive the correction platform 212 to rotate around the rotating rod 213. The rotating rod 213 will drive the swing support rod 214 to rotate synchronously. One end of the swing support rod 214 stretches the ring spring 217 and the other end compresses the ring spring 217. The elastic tension of the ring spring 217 forms a reset force, which drives the correction platform 212 to self-correct and return to the center position, thereby pushing the aluminum composite panel back to the center conveying position. This achieves real-time elastic correction and reduces the possibility of panels shifting into the hot pressing area, resulting in defective products.

[0029] During the correction process, the protective rubber sleeve 218 provides comprehensive protection for the ring spring 217, preventing dust and debris in the production environment from entering the gap of the ring spring 217, ensuring the elastic performance and service life of the spring, and at the same time preventing the ring spring 217 from directly contacting the sheet or equipment parts and causing scratch damage. After correction, the aluminum-plastic sheet is smoothly conveyed between the upper pressure roller 112 and the lower pressure roller 113 to complete the hot pressing process. The connection between feeding and hot pressing is smooth, effectively improving the finished product qualification rate.

[0030] When it is necessary to change to aluminum composite panels of different widths for production, simply turn the handwheel 228 again to overcome the thrust of the pre-tightening spring 220 and adjust the spacing of the guide rollers 210. The operation is convenient and highly adaptable.

[0031] It should be noted that the control of the upper pressure roller 112 and the lower pressure roller 113 in this application can be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.
