Description

Technical Field

[0001] This invention relates to the field of coating equipment technology, and in particular to an automatic coating equipment for WPC door panels. Background Technology

[0002] WPC, or wood-plastic composite material, is an environmentally friendly material made by combining thermoplastic resin as a matrix with plant fiber fillers through a composite process. WPC door panels have many advantages such as being waterproof and moisture-proof, insect-proof and moth-proof, having strong dimensional stability, being environmentally friendly and formaldehyde-free, and being recyclable. They are widely used in interior decoration, kitchen and bathroom spaces, and customized furniture, and are a high-quality alternative to traditional wooden door panels.

[0003] Most existing lamination equipment has a single-sided lamination structure, which can only complete the lamination of one side of the door panel in a single feeding operation. If double-sided lamination of WPC door panels is required, the door panels need to be manually flipped over for a second feeding operation. This not only significantly increases the process time and reduces production efficiency, making it difficult to adapt to the needs of large-scale continuous production, but also easily causes scratches, wear, and dirt on the already laminated surface during the flipping process, resulting in a significant decrease in the yield of finished products. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an automatic film coating device for WPC door panels.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an automatic film coating device for WPC door panels, comprising a first conveyor for roller conveying, a box fixed on one side of the first conveyor, two hot press rollers rotatably connected to the box and capable of automatic heating being disposed through the side wall of the box, an electromagnetic coil being disposed inside the hot press roller, the electromagnetic coil generating eddy currents in the metal roller body to achieve self-heating of the roller body, two unwinding rollers rotatably connected to the box being disposed through the side wall of the box, and a drive mechanism for driving the two hot press rollers to rotate synchronously in opposite directions and the two unwinding rollers to rotate synchronously in opposite directions being disposed on the box.

[0006] By adopting the above technical solution, the film on the two unwinding rollers is first passed between the two hot press rollers. Then, the WPC door panel to be processed is placed on the top of the roller of the first conveyor, and the roller automatically moves the WPC door panel between the two hot press rollers. At this time, the two sides of the WPC door panel are respectively bonded to the two films. Under the action of the electromagnetic coil, the two hot press rollers heat themselves and act on the film. The molten layer on the film wall melts and adheres to the surface of the WPC door panel. At the same time, the driving mechanism drives the two unwinding rollers and the two hot press rollers to rotate synchronously, so as to realize the automatic movement and film coating of the two sides of the WPC door panel. Compared with the existing technology, which can only coat one side at a time, the film coating efficiency of the device is improved.

[0007] Furthermore, the driving mechanism includes a driving assembly, which includes a first worm gear that passes through the top of the housing and is rotatably connected to the housing, two first worm wheels that are respectively fixedly sleeved on two unwinding rollers, a second worm gear that passes through the top of the housing and is rotatably connected to the housing, and two second worm wheels that are respectively fixedly sleeved on two hot press rollers. The first worm gear has two meshing grooves of equal pitch and opposite rotation direction. The two first worm wheels are respectively disposed on the two meshing grooves and meshed together. The second worm gear has two meshing grooves of equal pitch and opposite rotation direction. The two second worm wheels are respectively disposed on the two meshing grooves and meshed together. The driving mechanism also includes a rotating assembly for driving the first worm gear and the second worm gear to move synchronously.

[0008] By adopting the above technical solution, the rotating component drives the first worm and the second worm to rotate, thereby driving the first worm wheel meshing with the first worm and the second worm wheel meshing with the second worm to rotate synchronously. Since the first worm has two meshing grooves with equal pitch and opposite rotation direction, the two first worm wheels are respectively set on the two meshing grooves and meshed together. The second worm has two meshing grooves with equal pitch and opposite rotation direction, and the two second worm wheels are respectively set on the two meshing grooves and meshed together. Thus, the operation of the two first worm wheels rotating synchronously in opposite directions and the two second worm wheels rotating synchronously in opposite directions can be realized.

[0009] Furthermore, the rotating assembly includes a drive housing fixed to the top of the housing and a rotary motor fixed to the top of the drive housing. The output end of the rotary motor passes through the top of the drive housing and is rotatably connected to the drive housing. The rotating assembly also includes a drive gear fixedly sleeved on the output end of the rotary motor and located inside the drive housing, and two driven gears respectively fixed to the upper ends of the first worm and the second worm and both located inside the drive housing. Both driven gears mesh with the drive gear.

[0010] By adopting the above technical solution, the rotary motor drives the drive gear to rotate, which in turn drives the driven gear meshing with the drive gear, the first worm fixed to the driven gear, and the second worm to rotate synchronously. The method of driving through the same drive structure is beneficial to improving the synchronicity of the rotation of the unwinding roller and the hot pressing roller.

[0011] Furthermore, the housing is provided with a limiting mechanism, which includes two upper rollers that are both inserted through the side wall of the housing and rotatably connected to the housing, two lower rollers that are both inserted through the side wall of the housing and rotatably connected to the housing, two third worm gears that are respectively fixedly sleeved on the two upper rollers and located inside the housing, and two fourth worm gears that are respectively fixedly sleeved on the two lower rollers and located inside the housing. The first worm has a third meshing groove and a fourth meshing groove. The two third worm gears are symmetrically arranged about the axis of the first worm and are both meshed with the third meshing groove. The two fourth worm gears are symmetrically arranged about the axis of the first worm and are both meshed with the fourth meshing groove. The rotation direction of the third meshing groove is opposite to that of the fourth meshing groove, and the pitch of the third meshing groove is equal to that of the fourth meshing groove.

[0012] By adopting the above technical solution, when the first worm rotates, since the first worm's axis is symmetrically arranged and both are engaged with the fourth meshing groove, and the rotation direction of the third meshing groove is opposite to that of the fourth meshing groove, and the pitch of the third meshing groove is equal to that of the fourth meshing groove, the two third worm wheels and the two fourth worm wheels can rotate synchronously in opposite directions, thereby causing the two upper rollers and the two lower rollers to rotate synchronously in opposite directions. In practical use, the film on the upper unwinding roller is passed between the two upper rollers, and the film on the lower unwinding roller is passed between the two lower rollers, which can improve the stability of film conveying.

[0013] Furthermore, the housing is equipped with an air-cooling mechanism, which includes an air-cooling assembly. The air-cooling assembly includes an air-cooling box fixed to one side of the housing and having an internal hollow structure, two electric rollers (first type) rotatably installed inside the air-cooling box and having a self-rotating function, two exhaust shells (second type) fixed to the bottom wall and top wall of the air-cooling box respectively and having a hollow structure, and two electric rollers (third type) rotatably installed inside the air-cooling box and having a self-rotating function. The side walls on both sides of the air-cooling box are provided with conveying through holes for the WPC door panel to pass through after molding. The two electric rollers (first type) rotate in opposite directions, and the two electric rollers (second type) rotate in opposite directions. The side walls of the two exhaust shells that are close to each other are provided with ventilation holes. The air-cooling mechanism also includes a refrigeration assembly for supplying cold air to the two exhaust shells and discharging the cooled gas out of the air-cooling box.

[0014] By adopting the above technical solution, the WPC door panel after lamination first enters the air-cooling box through a conveying hole on one side, passes between two electric rollers rotating in opposite directions, then passes between two electric rollers rotating in opposite directions, and finally exits the air-cooling box through a conveying hole on the other side. During this process, the refrigeration unit supplies cold air to the two exhaust shells. The cold air on the two exhaust shells is discharged from the exhaust shells through the vent holes and acts on both sides of the WPC door respectively. Finally, the refrigeration unit discharges the hot air into the air-cooling box, which can accelerate the solidification speed of the WPC door after lamination.

[0015] Furthermore, the refrigeration assembly includes an air cooler fixed to the top of the air-cooled box, a first three-way pipe fixed and connected to the air inlet end of the air cooler, a second three-way pipe fixed and connected to the air outlet end of the air cooler, and a second conveyor fixed to the side wall of the air-cooled box away from the box body and used for roller conveying. The two ends of the second three-way pipe away from the air cooler are respectively connected to two exhaust shells, and the two ends of the first three-way pipe away from the air cooler are connected to the inside of the air-cooled box.

[0016] By adopting the above technical solution, the air cooler cools the air and discharges the cold air from its outlet to the second three-way pipe. Then, the cold air is discharged from the second three-way pipe into the two exhaust shells. Subsequently, the heated gas enters the exhaust shell through the vent and is discharged from the first three-way pipe to the air inlet of the air cooler, thus realizing the recycling of gas.

[0017] Furthermore, the first conveyor is equipped with a centering assembly, which includes a placement frame fixed to the end of the first conveyor away from the housing, two centering plates slidably disposed within the placement frame, a crossbar penetrating the side wall of the placement frame and slidably engaged with the placement frame, an electro-hydraulic push rod fixed to the side wall of the placement frame, and multiple rollers rotatably mounted on the bottom wall of the placement frame. The crossbar is fixed to the centering plate, the push rod end of the electro-hydraulic push rod penetrates the side wall of the placement frame and slidably engages with the placement frame, and the push rod end of the electro-hydraulic push rod is fixed to the centering plate. The number of centering plates, the number of crossbars, and the number of electro-hydraulic push rods are equal and their positions correspond one-to-one. The first conveyor is also equipped with a feeding mechanism for automatically moving the WPC door panels to be processed placed in the placement frame to the top of the first conveyor roller.

[0018] By adopting the above technical solution, the WPC door to be processed is first placed on the bottom wall of the placement rack and located between two centering plates. Then, the electric hydraulic push rods on both sides are activated and their ends are extended, thereby driving the two centering plates to move closer to each other and center the WPC door, so as to ensure that the feeding mechanism can accurately pick up or place the WPC door.

[0019] Furthermore, the feeding mechanism includes a moving component, which includes a frame fixed to the top of the first conveyor, two hollow movable boxes slidably disposed on the frame, a crossbar fixed between the two movable boxes, and a rack fixed to the top of the frame. The movable boxes are provided with limiting through holes for the rack to pass through. The feeding mechanism also includes a displacement component for driving the movable boxes to move automatically and a feeding component for automatically gripping and placing the WPC door panel.

[0020] By adopting the above technical solution, the operation displacement component drives the moving box to move automatically, and the feeding component can also move from above the first conveyor to above the placement rack to pick up the WPC door in the placement rack. Then, the operation displacement component drives the moving box to move automatically in the opposite direction and reset, and the feeding component moves from above the placement rack to above the first conveyor to place the WPC door to be processed on the roller of the first conveyor, thus realizing the purpose of automatic feeding of WPC doors and improving the processing efficiency of the device.

[0021] Furthermore, the number of displacement components is equal to the number of moving boxes and their positions correspond one-to-one. Each displacement component includes a drive rod rotatably installed inside the moving box, a displacement gear fixedly sleeved on the drive rod and meshing with a rack, and a displacement motor fixed on the moving box and driving the drive rod to rotate.

[0022] By adopting the above technical solution, the displacement motor drives the drive rod to rotate, which in turn drives the displacement gear fixed to the drive rod to rotate. The displacement gear rolls along the tooth surface of the rack, thereby realizing the movement of the entire moving box.

[0023] Furthermore, the feeding assembly includes a vertical rod that passes through the top of the cross frame and slides with the cross frame, a lifting plate fixed to the lower end of the vertical rod, an electric suction cup fixed to the bottom of the lifting plate, and an electric hydraulic push rod II fixed to the top of the cross frame. The push rod end of the electric hydraulic push rod II passes through the top of the cross frame and slides with the cross frame. The push rod end of the electric hydraulic push rod II is fixedly connected to the lifting plate.

[0024] By adopting the above technical solution, the second electro-hydraulic push rod extends and retracts at its end, which in turn drives the lifting plate fixed to the end of the second electro-hydraulic push rod, the vertical rod fixed to the lifting plate, and the electric suction cup fixed to the lifting plate to rise and fall until the suction end of the horizontal frame is in contact with the top of the WPC door. The horizontal frame then activates its power supply and suction-fixes the WPC door, ensuring its stability when gripping or placing. Furthermore, by adjusting the height of the lifting plate, it can accommodate gripping WPC doors in various stacking positions.

[0025] In summary, the present invention has the following beneficial effects: In this application, by improving the existing structure, the automatic moving film coating of both sides of the WPC door panel is realized. Compared with the prior art, which can only coat one side at a time, the film coating efficiency of the device is improved. Attached Figure Description

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-7As shown in the figure, this application discloses an automatic laminating device for WPC door panels, including a first conveyor 1, a drive mechanism 5, a limiting mechanism 6, an air-cooling mechanism 7, a centering component 9, and a feeding mechanism 10. The first conveyor 1 is a rolling conveyor. A housing 2 is fixed on one side of the first conveyor 1. Two hot press rollers 3, which are rotatably connected to the housing 2 and can be automatically heated, are installed through the side wall of the housing 2. An electromagnetic coil is installed inside the hot press roller 3. The electromagnetic coil generates eddy currents in the metal roller body, realizing the self-heating of the roller body. Two unwinding rollers 4, which are rotatably connected to the housing 2, are installed through the side wall of the housing 2. First, the film on the two unwinding rollers 4 is passed between the two hot press rollers 3. Then, the WPC door panel to be processed is placed on the top of the drum of the first conveyor 1, and the WPC door panel is automatically moved between the two hot press rollers 3 by the drum. At this time, the two sides of the WPC door panel are respectively bonded to the two films. Under the action of the electromagnetic coil, the two hot press rollers 3 heat themselves and act on the film. The molten layer on the film wall melts and adheres to the surface of the WPC door panel. At the same time, the driving mechanism 5 drives the two unwinding rollers 4 and the two hot press rollers 3 to rotate synchronously, so as to realize the automatic moving and film coating of the two sides of the WPC door panel. Compared with the existing technology, which can only coat one side at a time, the film coating efficiency of the device is improved.

[0030] A drive mechanism 5 is mounted on the housing 2. The drive mechanism 5 drives two hot press rollers 3 to rotate synchronously in opposite directions and two unwind rollers 4 to rotate synchronously in opposite directions. The drive mechanism 5 includes a drive assembly 51 and a rotation assembly 52. ​​The drive assembly 51 includes a first worm 511, a first worm wheel 512, a second worm 513, and a second worm wheel 514. The first worm 511 passes through the top of the housing 2 and is rotatably connected to the housing 2. Two first worm wheels 512 are provided. The first worm 511 has two meshing grooves with equal pitch and opposite directions of rotation. The two first worm wheels 512 are respectively mounted on the two meshing grooves and are meshed together. The two first worm wheels 512 are respectively fixedly sleeved on the two unwind rollers 4. The second worm 513 passes through the top of the housing 2 and is rotatably connected to the housing 2. Two second worm wheels 514 are provided, and the two second worm wheels 514 are respectively fixedly sleeved on the two hot press rollers 3. The second worm 513 has two meshing grooves with equal pitch and opposite directions of rotation. Two second worm wheels 514 are respectively disposed on the two meshing grooves and are meshed together. The rotating assembly 52 drives the first worm 511 and the second worm 513 to rotate, thereby driving the first worm wheel 512 meshing with the first worm 511 and the second worm wheel 514 meshing with the second worm 513 to rotate synchronously. Since the first worm 511 has two meshing grooves with equal pitch and opposite directions of rotation, and the two first worm wheels 512 are respectively disposed on the two meshing grooves and are meshed together, and the second worm 513 has two meshing grooves with equal pitch and opposite directions of rotation, and the two second worm wheels 514 are respectively disposed on the two meshing grooves and are meshed together, the operation of the two first worm wheels 512 rotating synchronously in opposite directions and the two second worm wheels 514 rotating synchronously in opposite directions can be realized.

[0031] The rotating assembly 52 drives the first worm gear 511 and the second worm gear 513 to move synchronously. The rotating assembly 52 includes a drive housing 521, a rotary motor 522, a driving gear 523, and a driven gear 524. The drive housing 521 is fixed to the top of the housing 2, and the rotary motor 522 is fixed to the top of the drive housing 521. The output end of the rotary motor 522 passes through the top of the drive housing 521 and is rotatably connected to the drive housing 521. The driving gear 523 is fixedly sleeved on the output end of the rotary motor 522 and located inside the drive housing 521. There are two driven gears 524, which are respectively fixed to the upper ends of the first worm gear 511 and the second worm gear 513 and are both located inside the drive housing 521. Both driven gears 524 mesh with the driving gear 523. The operation of the rotary motor 522 drives the drive gear 523 to rotate, which in turn drives the driven gear 524 meshing with the drive gear 523, the first worm 511 fixed to the driven gear 524, and the second worm 513 to rotate synchronously. The method of driving through the same drive structure is beneficial to improving the synchronicity of the rotation of the unwinding roller 4 and the hot pressing roller 3.

[0032] A limiting mechanism 6 is installed on the housing 2. The limiting mechanism 6 includes an upper roller 61, a lower roller 62, a third worm gear 63, and a fourth worm gear 64. There are two upper rollers 61, both of which penetrate the side wall of the housing 2 and are rotatably connected to the housing 2. There are two lower rollers 62, both of which penetrate the side wall of the housing 2 and are rotatably connected to the housing 2. There are two third worm gears 63, which are respectively fixedly sleeved on the two upper rollers 61 and located inside the housing 2. The first worm 511 has a third meshing groove and a fourth meshing groove. The two third worm gears 63 are symmetrically arranged about the axis of the first worm 511 and are both meshed with the third meshing groove. There are two fourth worm gears 64, which are respectively fixedly sleeved on the two lower rollers 62 and located inside the housing 2. Two fourth worm gears 64 are symmetrically arranged about the axis of the first worm 511 and are both engaged with the fourth meshing groove. The rotation direction of the third meshing groove is opposite to that of the fourth meshing groove, and the pitch of the third meshing groove is equal to that of the fourth meshing groove. When the first worm 511 rotates, because the first worm 511 is symmetrically arranged about its axis and is engaged with the fourth meshing groove, the rotation direction of the third meshing groove is opposite to that of the fourth meshing groove, and the pitch of the third meshing groove is equal to that of the fourth meshing groove, the two third worm gears 63 and the two fourth worm gears 64 can rotate synchronously in opposite directions, thereby causing the two upper rollers 61 and the two lower rollers 62 to rotate synchronously in opposite directions. In practical use, the film of the upper unwind roller 4 is passed between the two upper rollers 61, and the film of the lower unwind roller 4 is passed between the two lower rollers 62, which can improve the stability of film conveying.

[0033] The air-cooling mechanism 7 is mounted on the housing 2 and includes an air-cooling component 71 and a refrigeration component 72. The air-cooling component 71 includes an air-cooling box 711, a first electric roller 712, an exhaust casing 713, and a second electric roller 714. The air-cooling box 711 is fixed to one side of the housing 2 and has a hollow internal structure. Both side walls of the air-cooling box 711 have through-holes 8 for the WPC door panel to pass through after molding. Two first electric rollers 712 rotate in opposite directions, and there are two first electric rollers 712. Both first electric rollers 712 are rotatably mounted inside the air-cooling box 711 and have a self-rotation function. There are two exhaust casings 713. The two exhaust casings 713 are respectively fixed to the bottom and top walls of the air-cooling box 711 and have a hollow structure. There are two second electric rollers 714. Both second electric rollers 714 are rotatably mounted inside the air-cooling box 711 and have a self-rotation function. The two electric rollers 714 rotate in opposite directions, and ventilation holes are provided through the side walls of the two exhaust shells 713 that are close to each other. After the WPC door panel is coated, it first enters the air-cooling box 711 through the conveying hole 8 on one side, passes between the two electric rollers 712 that rotate in opposite directions, then passes between the two electric rollers 714 that rotate in opposite directions, and finally exits the air-cooling box 711 through the conveying hole 8 on the other side. During this process, the cooling component 72 supplies cold air to the two exhaust shells 713. The cold air on the two exhaust shells 713 is discharged from the exhaust shells 713 through the ventilation holes and acts on both sides of the WPC door respectively. Finally, the cooling component 72 discharges the air with heat into the air-cooling box 711, which can accelerate the solidification speed of the WPC door after coating.

[0034] The refrigeration assembly 72 supplies cold air to the two exhaust shells 713 and discharges the cooled gas out of the air-cooled box 711. The refrigeration assembly 72 includes an air cooler 721, a first three-way pipe 722, and a second three-way pipe 723. The air cooler 721 is fixed to the top of the air-cooled box 711, and the first three-way pipe 722 is fixed and connected to the air inlet end of the air cooler 721. The two ends of the second three-way pipe 723 away from the air cooler 721 are respectively connected to the two exhaust shells 713, and the second three-way pipe 723 is fixed and connected to the air outlet end of the air cooler 721. The two ends of the first three-way pipe 722 away from the air cooler 721 are connected to the inside of the air-cooled box 711, and a second conveyor 724 is fixed to the side wall of the air-cooled box 711 away from the box body 2 and is used for roller conveying. The air cooler 721 cools the air and discharges the cold air from its outlet to the second three-way pipe 723. Then, the air is discharged from the second three-way pipe 723 into the two exhaust shells 713. Subsequently, the heated gas enters the exhaust shell 713 through the vent and is discharged from the first three-way pipe 722 to the air inlet of the air cooler 721, thus realizing the recycling of the gas.

[0035] The centering assembly 9 is mounted on the first conveyor 1 and includes a placement frame 91, a centering plate 92, a crossbar 93, an electro-hydraulic push rod 94, and rollers 95. The placement frame 91 is fixed to the end of the first conveyor 1 away from the housing 2. There are two centering plates 92. Both centering plates 92 are slidably mounted inside the placement frame 91. The crossbar 93 passes through the side wall of the placement frame 91 and slides in cooperation with the placement frame 91. The crossbar 93 is fixed to the centering plate 92. The electro-hydraulic push rod 94 is fixed to the side wall of the placement frame 91. The push rod end of the electro-hydraulic push rod 94 passes through the side wall of the placement frame 91 and slides in cooperation with the placement frame 91. The push rod end of the electro-hydraulic push rod 94 is fixed to the centering plate 92. The number of centering plates 92, the number of crossbars 93, and the number of electro-hydraulic push rods 94 are equal and their positions correspond one-to-one. There are multiple rollers 95. Multiple rollers 95 are rotatably mounted on the inner bottom wall of the placement rack 91. First, the WPC door to be processed is placed on the inner bottom wall of the placement rack 91 and positioned between two centering plates 92. Then, the electric hydraulic push rods 94 on both sides are activated and their ends are extended, thereby driving the two centering plates 92 to move closer to each other and center the WPC door, ensuring that the feeding mechanism 10 can accurately pick up or place the WPC door.

[0036] A feeding mechanism 10 is mounted on the first conveyor 1. The feeding mechanism 10 automatically moves the WPC door panels to be processed, placed in the placement rack 91, to the top of the rollers of the first conveyor 1. The feeding mechanism 10 includes a moving component 101, a displacement component 102, and a feeding component 103. The moving component 101 includes a frame 1011, a moving box 1012, a crossbar 1013, and a rack 1014. The frame 1011 is fixed to the top of the first conveyor 1. Two moving boxes 1012 are provided. The two moving boxes 1012 are slidably mounted on the frame 1011 and have a hollow structure. The crossbar 1013 is fixed between the two moving boxes 1012. The rack 1014 is fixed to the top of the frame 1011, and a limiting through hole 11 is provided through the moving box 1012 for the rack 1014 to pass through. The operation displacement component 102 drives the moving box 1012 to move automatically, and can also move the feeding component 103 from above the first conveyor 1 to above the placement rack 91, and pick up the WPC door in the placement rack 91. Then, the operation displacement component 102 drives the moving box 1012 to move automatically in the reverse direction and reset, and the feeding component 103 moves from above the placement rack 91 to above the first conveyor 1, and places the WPC door to be processed on the roller of the first conveyor 1, thus realizing the purpose of automatic feeding of WPC doors, which is conducive to improving the processing efficiency of the device.

[0037] The displacement assembly 102 is used to drive the movable box 1012 to move automatically. The number of displacement assemblies 102 is equal to the number of movable boxes 1012, and their positions correspond one-to-one. The displacement assembly 102 includes a drive rod 1021, a displacement gear 1022, and a displacement motor 1023. The drive rod 1021 is rotatably mounted inside the movable box 1012.

The displacement motor 1023 is fixed on the movable box 1012 and drives the drive rod 1021 to rotate. When the displacement motor 1023 operates, it drives the drive rod 1021 to rotate, which in turn drives the displacement gear 1022, which is fixed to the drive rod 1021, to rotate. The displacement gear 1022 rolls along the tooth surface of the rack 1014, thereby realizing the overall movement of the movable box 1012.

[0038] The loading assembly 103 automatically clamps and places the WPC door panel. The loading assembly 103 includes a vertical rod 1031, a lifting plate 1032, an electric suction cup 1033, and a second electric hydraulic push rod 1034. The vertical rod 1031 passes through the top of the horizontal frame 1013 and slides in engagement with the horizontal frame 1013. The lifting plate 1032 is fixed to the lower end of the vertical rod 1031. The electric suction cup 1033 fixes the bottom of the lifting plate 1032, and the second electric hydraulic push rod 1034 is fixed to the top of the horizontal frame 1013. The push rod end of the second electric hydraulic push rod 1034 passes through the top of the horizontal frame 1013 and slides in engagement with the horizontal frame 1013. The push rod end of the second electric hydraulic push rod 1034 is fixedly connected to the lifting plate 1032. The operation of the second electro-hydraulic push rod 1034 causes its push rod end to extend and retract, which in turn drives the lifting plate 1032, the vertical rod 1031, and the electric suction cup 1033, all fixed to the end of the push rod 1034, to rise and fall until the suction end of the crossbeam 1013 is in contact with the top of the WPC door. The crossbeam 1013 then activates its power supply and suctions and fixes the WPC door in place, ensuring the stability of the WPC door during gripping or placement. Furthermore, by adjusting the height of the lifting plate 1032, it can accommodate gripping WPC doors in various stacking positions.
