Description

Technical Field

[0001] This application relates to the field of material processing equipment technology, and in particular to an automatic paper-faced gypsum board assembly machine. Background Technology

[0002] Paper-faced gypsum board, as a new type of lightweight building material, has been widely used in modern construction due to its advantages such as sound insulation, heat insulation, fire resistance, lightweight, and convenient construction. In the automated production process of gypsum board, a key step is flipping the wet gypsum board after it has been cut. Freshly cut gypsum board is usually in a state where the gypsum core layer is facing up and the facing paper (the future decorative surface) is facing down. To allow the facing paper to shrink freely during the subsequent drying process, thus achieving excellent flatness and a stable geometric shape, it must first be flipped 180° so that the facing paper is facing up. After drying, to protect the flat decorative surface from scratches or contamination during storage and transportation, two gypsum boards are usually stacked together. Therefore, efficient and reliable flipping and stacking equipment is one of the core pieces of equipment for ensuring the automation level of the gypsum board production line and the quality of the final product.

[0003] Currently, equipment used in the industry to achieve gypsum board flipping or lamination typically employs a large rotating cage structure. Six or more sets of flippers are evenly arranged around the circumference of the cage. During production, gypsum boards are continuously fed into the cage, and as the cage rotates synchronously, the boards are clamped by the flipper arms and flipped 180°. The advantage of this design is its ability to achieve continuous flipping at medium to high speeds. However, its inherent drawbacks are also significant: the equipment is bulky and occupies a large space. The rotating cage requires a sufficiently large diameter to accommodate the rotation path of the flipper arms, posing a serious challenge to the compact layout of modern production workshops. Secondly, the massive rotating cage structure generates a large moment of inertia. During frequent starts, stops, accelerations, and decelerations, it produces enormous impact loads. This not only severely tests the drive system, such as the servo motor and reduction gear, but also easily leads to mechanical vibration and fatigue damage to key components, thus affecting the long-term stable operation and service life of the equipment. Utility Model Content

[0004] To address the aforementioned issues, this application provides an automatic paper-faced gypsum board assembly machine that effectively improves product qualification rates.

[0005] To achieve the above objectives, this application designs an automatic gypsum board assembly machine, comprising a frame and a drive motor. Two flip-plate assemblies are symmetrically arranged on both sides of the frame. Each flip-plate assembly includes multiple plates, one end of which is pivotally connected to the frame. The drive motor is connected to each plate arm via a transmission mechanism to drive the plates of the two flip-plate assemblies to synchronously flip between a bearing position and an assembly position. In the bearing position, the plates of the two flip-plate assemblies are located on the same horizontal plane to form a conveying plane. In the assembly position, the plates of the two flip-plate assemblies flip upwards relative to the conveying plane and move closer to each other to form an assembly space. In the gypsum board conveying direction, the maximum flip angle of the plate arm of the upstream flip-plate assembly is greater than the maximum flip angle of the plate arm of the downstream flip-plate assembly.

[0006] Preferably, the transmission mechanism includes a tilting shaft, a crank-connecting rod mechanism, and a driven connecting rod mechanism. Two tilting shafts are rotatably provided on the frame corresponding to the two flip-plate assemblies. The middle positions of the plate arms are respectively connected to the corresponding tilting shafts through a driven connecting rod mechanism. The drive motor is connected to the two tilting shafts through the crank-connecting rod mechanism to drive the two tilting shafts to rotate synchronously, and converts the rotation of the tilting shafts into the tilting motion of the plate arms through the driven connecting rod mechanism.

[0007] Preferably, the driven linkage mechanism includes a swing arm and a threaded telescopic rod. One end of the swing arm is fixed to the flipping shaft, and one end of the threaded telescopic rod is hinged to the free end of the swing arm, while the other end is pivotally connected to the middle position of the plate arm.

[0008] Preferably, the drive motor is a hollow shaft geared motor.

[0009] Preferably, a plurality of first bearing seats are arranged on the frame along the axial direction of the flipping shaft, and the flipping shaft is rotatably mounted on the frame through the first bearing seats.

[0010] Preferably, the maximum flip angle of the flap arm of the upstream flap assembly is 95°; and the maximum flip angle of the flap arm of the downstream flap assembly is 85°.

[0011] Preferably, the frame is welded from a rectangular tube extending axially along the flip axis.

[0012] Preferably, a second bearing seat is fixedly provided on the top side of the frame, and multiple second bearing seats are arranged along the length direction of the frame, with one end of each plate arm pivotally connected to the frame through the corresponding second bearing seat.

[0013] Preferably, the length of the transport plane is 7200mm to 16000mm.

[0014] The automatic gypsum board laminating machine designed in this application uses a single drive motor to synchronously drive two flip-plate components with different maximum flip angles via a symmetrically arranged crank-connecting rod mechanism. This ensures smooth transfer and gentle acceptance of the gypsum board during the air flipping process, fundamentally avoiding board drop and reducing the possibility of damage to the board, thus effectively improving the product qualification rate. At the same time, the single-motor unidirectional rotation drive replaces the traditional multi-motor or motor forward and reverse control, simplifying the control system, eliminating current surges and transmission gap errors, improving the stability and reliability of equipment operation, and significantly reducing energy consumption.

[0019] The components include: frame 10, first bearing seat 11, second bearing seat 12, motor bracket 20, drive shaft 21, flip plate assembly 30, plate arm 31, transmission mechanism 40, flipping shaft 41, crank connecting rod mechanism 42, driven connecting rod mechanism 43, swing arm 431, threaded telescopic rod 432, bearing and conveying plane 100, and assembly space 200. Detailed Implementation

[0020] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0021] like Figures 1 to 4 As shown in the figure, the automatic gypsum board assembly machine described in this embodiment mainly includes a frame 10, a drive motor (not shown in the figure), and two flip-plate assemblies 30 symmetrically arranged on both sides of the frame 10.

[0022] Specifically, the frame 10 is the supporting foundation for the entire device. In this embodiment, the frame 10 is made of a rectangular tube, such as a rectangular steel tube, extending axially along the flip axis 41, and the accuracy of each mounting surface is ensured after shaping to provide sufficient strength and stability.

[0023] Each of the flipping plate assemblies 30 includes multiple plate arms 31. A second bearing seat 12 is fixedly provided on the top side of the frame 10. Multiple second bearing seats 12 are arranged along the length direction of the frame 10. One end of each plate arm 31 is pivotally connected to the frame 10 through the corresponding second bearing seat 12, ensuring the smoothness and stability of its flipping action.

[0024] The drive motor provides power to the entire automatic laminating machine. It is connected to each of the plate arms 31 via a transmission mechanism 40, which drives the plate arms 31 of the two flipping assemblies 30 to flip synchronously between a bearing position and a laminating position. In this embodiment, the drive motor is a hollow shaft geared motor.

[0025] In specific implementation, such as Figure 2 , Figure 3 , Figure 4 As shown, the transmission mechanism 40 includes a tilting shaft 41, a crank-connecting rod mechanism 42, and a driven connecting rod mechanism 43. Two tilting shafts 41 are rotatably mounted on the frame 10 corresponding to the two flap assemblies 30, meaning one tilting shaft 41 corresponds to each flap assembly 30 on each side. Two crank-connecting rod mechanisms 42 are also provided corresponding to the tilting shafts 41. Multiple first bearing seats 11 are arranged along the axial direction of the tilting shaft 41 on the frame 10. The tilting shaft 41 is rotatably mounted on the frame 10 via the first bearing seats 11, ensuring its rotational accuracy and stability.

[0026] The drive motor is connected to the two tilting shafts 41 via the crank-connecting rod mechanism 42, driving the two tilting shafts 41 to rotate synchronously. The rotation of the tilting shafts 41 is then converted into the tilting motion of the plate arm 31 via the driven connecting rod mechanism 43. This method of single-motor centralized drive of two tilting shafts 41 effectively avoids the asynchronous problems that may occur with multi-motor drives, simplifies the control system, and reduces energy consumption. In specific implementation, such as... Figure 2 As shown, the drive motor is mounted on one end of the flip shaft 41 via the motor bracket 20 and is connected to the drive shaft 21. The two ends of the drive shaft 21 are respectively connected to the ends of the two flip shafts 41 via a crank-connecting rod mechanism 42.

[0027] like Figure 2 , Figure 3As shown, the middle positions of the plate arms 31 are respectively connected to the corresponding flipping shafts 41 via a driven linkage mechanism 43. The rotation of the flipping shafts 41 is converted into the flipping motion of the plate arms 31 through the driven linkage mechanism 43. In this embodiment, the driven linkage mechanism 43 preferably includes a swing arm 431 and a threaded telescopic rod 432, wherein one end of the swing arm 431 is fixed to the flipping shaft 41, one end of the threaded telescopic rod 432 is hinged to the free end of the swing arm 431, and the other end is pivotally connected to the middle position of the plate arms 31, so as to form a four-bar linkage structure, ensuring the smoothness and controllability of the flipping motion.

[0028] like Figure 3 As shown, in the bearing position, the arm 31 of the two flap assemblies 30 are located on the same horizontal plane to form a conveying plane 100. The length of the conveying plane 100 is preferably between 7200mm and 16000mm to accommodate the production needs of gypsum boards of different specifications.

[0029] like Figure 4 As shown, at the joining position, when the device flips and joins the pieces, the plate arms 31 of the two flip plate assemblies 30 will simultaneously flip upward relative to the transport plane 100 and move closer to each other to form a joining space 200.

[0030] In the conveying direction of the gypsum board, the maximum flip angle of the plate arm 31 of the upstream flip assembly 30 is greater than that of the plate arm 31 of the downstream flip assembly 30. Specifically, the maximum flip angle of the plate arm 31 of the upstream flip assembly 30 is 95°; the maximum flip angle of the plate arm 31 of the downstream flip assembly 30 is 85°.

[0031] This ensures that when the gypsum board flips from the upstream flip assembly 30 to its highest point or near its highest point, its center of gravity can smoothly transition to the plate arm 31 of the downstream flip assembly 30. Since the flip angle of the downstream plate arm 31 is relatively small, it forms an appropriate bearing slope, allowing the gypsum board to slide gently and smoothly from the upstream plate arm 31 to the downstream plate arm 31. This effectively avoids the common board-dropping phenomenon in the prior art and greatly protects the integrity and surface quality of the gypsum board.

[0032] The automatic gypsum board assembly machine provided in this application uses a single drive motor to synchronously drive two flip-plate assemblies with different maximum flip angles via a symmetrically arranged crank-connecting rod mechanism. This ensures smooth transfer and gentle acceptance of the gypsum board during the air flipping process, fundamentally avoiding board drop and reducing the possibility of damage to the board, thus effectively improving the product qualification rate. At the same time, the single-motor unidirectional rotation drive replaces the traditional multi-motor or motor forward and reverse rotation control, simplifying the control system, eliminating current surges and transmission gap errors, improving the stability and reliability of equipment operation, and significantly reducing energy consumption.
