Description

Technical Field

[0001] This utility model relates to the technical field of cement board production equipment, and in particular to an automatic pressing device for cement board reinforcing fiber mesh. Background Technology

[0002] Cement board is widely used in modern construction, especially in walls, floors, and roofs. To improve its crack resistance, thermal insulation, and sound insulation properties, reinforcing materials such as fiberglass mesh are usually added to its surface. Fiberglass mesh effectively enhances the crack resistance of cement board, reducing cracking and aging during long-term use, and improving its overall performance and durability.

[0003] However, in cement board production, the pressing of reinforcing fiber mesh is usually done manually or with semi-automatic equipment. Manual operation has certain limitations, such as low efficiency, uneven quality, and high labor intensity; while traditional semi-automatic equipment, although improving production efficiency, still suffers from drawbacks such as low precision, equipment complexity, and difficult maintenance. Therefore, there is an urgent need to develop a highly efficient, stable, and precise automatic pressing device that can reduce manual intervention, ensure the uniformity and firmness of mesh pressing, and improve the overall quality and production efficiency of cement boards. Utility Model Content

[0004] To address the problems mentioned above, this utility model provides an automatic pressing device for cement board reinforced fiber mesh, which effectively solves the problems of low efficiency, uneven quality, and high labor intensity of manual pressing, as well as the problems of low precision, complex equipment, and difficult maintenance of traditional semi-automatic equipment.

[0005] This utility model adopts the following technical solution: an automatic pressing device for cement board reinforced fiber mesh, including a belt conveyor. Several cement molds are provided on the surface of the belt conveyor belt. Reciprocating gear mechanisms are provided on both sides of the top of the belt conveyor frame. Each reciprocating gear mechanism includes a base mounted on the top of the belt conveyor frame. Optical shafts are installed on both sides of the top of the base. Two gear frames are fixedly connected to the surfaces of the two optical shafts by bolts. Gears are installed inside the gear frames. A rotating shaft is connected to the center of each gear. Eccentric couplings are rotatably connected to both sides of the rotating shafts. The two gears mesh with each other. Connecting rods are rotatably connected to both ends of the two rotating shafts. A connecting rod is connected between the two inner connecting rods. Two connecting blocks are connected to the bottom of the connecting rod. A pressing plate is connected to the bottom of the two connecting blocks. The eccentric couplings are connected to a belt drive device via a drive shaft.

[0006] Furthermore, the eccentric coupling includes a first rotary bearing and a second rotary bearing, the first rotary bearing and the second rotary bearing are connected by a connecting key, the first rotary bearing is rotatably connected to the rotary shaft, and the second rotary bearing is rotatably connected to the gear carrier through the drive shaft.

[0007] Furthermore, the belt drive device includes a driven pulley connected to the drive shaft, a servo motor is installed on one side of the frame of the belt conveyor, the output end of the servo motor is connected to a driving pulley, and the driving pulley and the driven pulley are connected by belt drive.

[0008] Furthermore, the lower surface of the pressure plate is covered with an elastic pressure layer.

[0009] Furthermore, the gear teeth are provided with a wear-resistant coating.

[0010] The advantages of this invention are as follows: This device adopts a fully automated operation mode, enabling continuous production of cement boards, significantly improving production efficiency, and reducing the time and cost of manual operation. The design of a reciprocating gear mechanism and eccentric coupling allows the pressing plate to perform precise vertical reciprocating motion, ensuring that the mesh is evenly pressed into the cement board surface and guaranteeing consistent quality of the surface reinforcement layer on each cement board. Through the cooperation of a servo motor and belt drive, the drive device can smoothly and accurately transmit motion, achieving automated operation, reducing reliance on manual labor, and improving the level of automation in production. The use of an elastic pressing layer covering the lower surface of the pressing plate effectively adapts to the surface shape of the mesh, ensuring close contact between the mesh and the cement board surface, avoiding the poor pressing effect caused by uneven pressure in traditional methods.

Therefore, they should not be construed as limitations on this utility model.

[0018] See Figure 1-4As shown, an automatic pressing device for cement board reinforced fiber mesh includes a belt conveyor 1. Several cement molds 2 are arranged on the surface of the belt conveyor 1. Reciprocating gear mechanisms 3 are arranged on both sides of the top of the frame of the belt conveyor 1. Each reciprocating gear mechanism 3 includes a base 301 mounted on the top of the frame of the belt conveyor 1. Optical shafts 302 are mounted on both sides of the top of the base 301. Two gear frames 303 are bolted to the surfaces of the two optical shafts 302. Gears 303 are arranged inside the gear frames 303. 4. A rotating shaft 305 is connected to the center of the gear 304. An eccentric coupling 306 is rotatably connected to both sides of the rotating shaft 305. The two gears 304 mesh with each other. The two ends of the two rotating shafts 305 are rotatably connected to the connecting rods 307. A connecting rod 308 is connected between the two connecting rods 307 on the inner side. Two connecting blocks 309 are connected to the bottom of the connecting rod 308. A pressure plate 310 is connected to the bottom of the two connecting blocks 309. The eccentric coupling 306 is connected to a belt drive device 311 through a drive shaft 312.

[0019] The eccentric coupling 306 includes a first rotary bearing 3061 and a second rotary bearing 3062. The first rotary bearing 3061 and the second rotary bearing 3062 are connected by a connecting key 3063. The first rotary bearing 3061 is rotatably connected to the rotary shaft 305, and the second rotary bearing 3062 is rotatably connected to the gear carrier 303 through the drive shaft 312. The dual bearing structure disperses the radial load generated by the eccentric motion and reduces the risk of bearing deformation under stress.

[0020] The belt drive device 311 includes a driven pulley 3111 connected to the drive shaft 312. A servo motor 3112 is installed on one side of the frame of the belt conveyor 1. The output end of the servo motor is connected to a drive pulley 3113. The drive pulley 3113 and the driven pulley 3111 are connected by belt drive. The belt drive device 311 smoothly transmits the rotational motion of the servo motor 3112 to the drive shaft 312 and the eccentric coupling 306, ensuring the working stability of the entire device and avoiding the problem of excessive mechanical load caused by direct drive.

[0021] The lower surface of the pressure mesh plate 310 is covered with an elastic pressure mesh layer, which can provide sufficient pressure to ensure that the mesh is firmly embedded in the cement surface, thereby enhancing the crack resistance and structural strength of the cement board.

[0022] The tooth surface of gear 304 is coated with a wear-resistant coating, which resists corrosion in the alkaline environment of cement and reduces the wear rate of the gear.

[0023] Working principle: The belt conveyor 1 continuously transports the cement slab with the cement mold 2 fixed to the pressing station. The servo motor 3112 drives the drive shaft 312 to rotate through the belt drive device 311. The drive shaft 312 drives the second rotary bearing 3062 of the eccentric coupling 306 to rotate. The first rotary bearing 3061 is linked through the connecting key 3063. The eccentric coupling 306 converts the rotational motion into the eccentric oscillation of the gear 304. The two meshing gears 304 drive the connecting rods 307 on both sides to swing synchronously through the rotating shaft 305. The connecting rods 307 drive the connecting rod 308 and the pressing plate 310 to make vertical reciprocating motion. When the pressing plate 310 presses down, the elastic pressing layer 313 adheres to the surface of the mesh and presses it evenly into the cement. After pressing is completed, the pressing plate 310 returns to its original position with the connecting rod 307. The belt conveyor 1 moves the cement slab to the next station, and the device enters the next cycle.
