Description

Technical Field

[0001] This utility model relates to the field of paper-faced gypsum board processing technology, specifically to an automatic feeding and sanding device for paper-faced gypsum board. Background Technology

[0002] During the molding and drying process, issues such as stress release, uneven thickness, or equipment precision can cause slight unevenness, ripples, or burrs on the surface of gypsum board. This can lead to insufficient adhesion of paint, wallpaper, or veneer materials, affecting the bonding between the coating and the substrate and preventing peeling or cracking later.

[0003] According to Chinese Patent Publication No. CN222308287U, "An Automatic Feeding and Grinding Device for Paper-faced Gypsum Board," the device is mainly described as follows: An external automatic feeding mechanism, mounted above a conveying assembly, transports the paper-faced gypsum board to the left side of the conveying assembly. The conveying assembly then moves the paper-faced gypsum board directly below the mounting frame. At this point, based on the dimensions of the paper-faced gypsum board, the handwheels on both sides are rotated to clamp and fix the sides of the paper-faced gypsum board using clamping plates and rubber pads. A motor and a lead screw drive a cylinder to slide left and right, and the cylinder then drives the grinding disc downwards. This allows a second motor and a rotating shaft to drive the grinding disc to grind the paper-faced gypsum board. This semi-automatic grinding method replaces the traditional manual grinding method, resulting in high grinding efficiency and low labor intensity, making it suitable for production line use.

[0004] Common automatic gypsum board feeding and sanding devices use a transverse conveyor mechanism to move the gypsum board, and then a longitudinally moving sanding device to sand the surface of the cut gypsum board, thereby achieving a smooth surface. During this process, clamps provide limiting. However, when paper-faced gypsum board is cut, rough edges and chipped corners will also occur on the four sides, affecting the processing effect of the paper-faced gypsum board. Utility Model Content

[0005] In view of the deficiencies in the existing technology, this utility model provides an automatic feeding and sanding device for paper-faced gypsum board, so as to improve the uniformity of the four sides of the paper-faced gypsum board and improve the processing effect of the paper-faced gypsum board.

[0006] The technical solution adopted by this utility model to solve the technical problem is: an automatic feeding and sanding device for paper-faced gypsum board, including a fixed plate, a first conveying mechanism, and a transverse sanding mechanism. A second conveying mechanism is rotatably connected to one side of the fixed plate. Two conveyor belts are arranged on the second conveying mechanism. An electric push rod is fixedly connected to the side of the two fixed plates that are far apart from each other. A connecting plate is fixedly connected to the output end of the electric push rod. Two first motors are fixedly connected to the side of the connecting plate that is far from the fixed plate. A rotating rod is fixedly connected to the output end of each first motor. A second sanding wheel is fixedly connected to the rotating rod. A connecting frame is fixedly connected to the fixed plate above the rotating rod. The bottom end of the connecting frame is fixedly connected to... The device includes a hydraulic push rod, the output end of which is fixedly connected to a movable frame. A pressure roller is rotatably connected to the bottom end of the movable frame. A support plate is provided on the bottom side of the fixed plate located on the second conveying mechanism. Hydraulic rods are fixedly connected to both sides of the upper end of the support plate. A fixed frame is fixedly connected to the output end of the hydraulic rods.

A third motor is fixedly connected inside the movable block. A third grinding wheel is fixedly connected to the output end of the third motor.

[0007] As a preferred technical solution of this utility model, a support roller is rotatably connected between the two fixed plates. The support roller contacts the upper side of the conveyor belt. By setting the support roller, it is easy to provide support for the conveyor belt and facilitate the smooth movement of the paper-faced gypsum board.

[0008] As a preferred technical solution of this utility model, an electric telescopic rod is fixedly connected to one side of each of the two fixed plates. A clamping plate is fixedly connected to the output end of the electric telescopic rod. The clamping plate corresponds to the upper side of the conveyor belt. By setting the electric telescopic rod, the clamping plate can be driven to clamp the conveyor belt, thereby facilitating the clamping of the gypsum board.

[0009] As a preferred technical solution of this utility model, an adjusting rod is threadedly connected to the clamping plate, and a sliding ball is rotatably embedded at the bottom end of the adjusting rod. By setting the adjusting rod and the sliding ball, the limiting effect of the clamping plate can be further improved, and the stable movement of the gypsum board can be enhanced.

[0010] As a preferred technical solution of this utility model, the card plate is rotatably connected to a limiting wheel on one side of the adjusting rod. The limiting wheel is located on the upper side of the conveyor belt. By setting the limiting wheel, the side of the gypsum board can be limited, thereby improving the stability of the gypsum board movement.

[0011] This utility model has the following advantages: by installing a second conveying mechanism on one side of the first conveying mechanism and the transverse grinding mechanism, and by using an electric telescopic rod to drive the clamping plate to limit the gypsum board, and by using a pressure roller to provide compression and limiting on the upper side of the gypsum board, the gypsum board on the second conveying mechanism can be moved and ground by using a second grinding wheel and a third grinding wheel, which can improve the grinding effect.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Please refer to the following: Figure 1-3The illustrated automatic feeding and sanding device for paper-faced gypsum board includes a fixed plate 1, a first conveying mechanism 2, and a transverse sanding mechanism 3 (both the first conveying mechanism 2 and the transverse sanding mechanism 3 are consistent with the sanding structure in the application document, and can only sand the two end faces of the gypsum board; the transverse sanding mechanism 3 includes a first sanding wheel, which can sand both end faces of the gypsum board). A second conveying mechanism 4 is rotatably connected to one side of the fixed plate 1. The second conveying mechanism 4 is equipped with two conveyor belts. The rotation of the conveyor belts on the second conveying mechanism 4 can cause the gypsum board to move on the second conveying mechanism 4, so that the second sanding wheel 8 can sand the two edges of the gypsum board, the side of the two fixed plates 1 that are far apart. An electric push rod 5 is fixedly connected. When the electric push rod 5 retracts, it drives the rotating rod 7 and the second grinding wheel 8 to move towards the second conveying mechanism 4, causing the second grinding wheel 8 to contact the edge of the gypsum board. At this time, the first motor starts and drives the rotating rod 7 and the second grinding wheel 8 to rotate, thus grinding the edge of the gypsum board. Simultaneously, the second grinding wheel 8 is located between two fixed plates 1, allowing for replacement with different grinding wheels to improve the grinding effect. A connecting plate 6 is fixedly connected to the output end of the electric push rod 5. Two first motors are fixedly connected to the side of the connecting plate 6 away from the fixed plate 1. The output end of each first motor is fixedly connected to the rotating rod 7, and the second grinding wheel 8 is fixedly connected to the rotating rod 7. The fixed plate 1... A connecting frame 9 is fixedly connected to the upper side of the rotating rod 7. A hydraulic push rod 10 is fixedly connected to the bottom end of the connecting frame 9. A moving frame 11 is fixedly connected to the output end of the hydraulic push rod 10. The hydraulic push rod 10 can drive the moving frame 11 and the pressure roller 12 to press down, thereby contacting the plasterboard on the second conveying mechanism 4 and providing a limiting effect to facilitate stable grinding by the second grinding wheel 8. The pressure roller 12 is rotatably connected to the bottom end of the moving frame 11. A support plate 13 is provided on the bottom side of the fixed plate 1 on the second conveying mechanism 4. Hydraulic rods 14 are fixedly connected to both sides of the upper end of the support plate 13. The extension and retraction of the hydraulic rods 14 can drive the fixed frame 15 to move up and down. The extension can make the third grinding wheel contact the plasterboard. The edges correspond to each other, and under shrinkage conditions, it can reduce the obstruction of the movement of the gypsum board. The output end of the hydraulic rod 14 is fixedly connected to the fixed frame 15. The fixed frame 15 is fixedly connected to one side of the second motor. The second motor drives the lead screw 16 to rotate, which can cause the moving block 17 to move, making it easier to grind the other two edges of the gypsum board. The output end of the second motor is fixedly connected to the lead screw 16. The moving block 17 is threadedly connected to the lead screw 16. Folding sleeves 22 are fixedly connected to both sides of the moving block 17. The ends of the two folding sleeves 22 that are far apart are fixedly connected to the fixed frame 15. The moving block 17 is fixedly connected to the third motor. The output end of the third motor is fixedly connected to the third grinding wheel.

[0016] Among them, a support roller 18 is rotatably connected between the two fixed plates 1. The support roller 18 contacts the upper side of the conveyor belt. By setting the support roller 18 to contact the conveyor belt, the stability of the conveyor belt in conveying gypsum board can be improved.

[0017] Among them, electric telescopic rods 19 are fixedly connected to the opposite sides of the two fixed plates 1. The output end of the electric telescopic rods 19 is fixedly connected to a clamping plate 20. The clamping plate 20 corresponds to the upper side of the conveyor belt. By setting the electric telescopic rods 19 to drive the clamping plate 20 to extend and retract, when there is plasterboard on the conveyor belt, the clamping plate 20 can be extended to cover part of the plasterboard, thereby providing stable positioning.

[0018] The plate 20 is threaded with an adjusting rod 21. The bottom end of the adjusting rod 21 is fitted with a sliding ball. Rotating the adjusting rod 21 allows the sliding ball to contact the plasterboard on the conveyor belt, thereby cooperating with the conveyor belt and support roller 18 to provide a limit on the plasterboard and facilitate the movement of the plasterboard.

[0019] The clamping plate 20 is rotatably connected to the limiting wheel 23 on one side of the adjusting rod 21. The limiting wheel 23 is located on the upper side of the conveyor belt. By setting the limiting wheel 23 to contact the side of the gypsum board, the friction caused by direct contact between the gypsum board and the side of the clamping plate 20 is reduced.

[0020] in, Figure 1 The drive motor, electric push rod 5, hydraulic push rod 10, hydraulic rod 14, electric telescopic rod 19, first motor, second motor and third motor used to drive the rotation of the roller can all be purchased from the market, and the execution program is provided by the equipment itself.

[0021] Working principle: The paper-faced gypsum board moves on the first conveyor mechanism 2. Through the electric telescopic rod 19 and the clamping plate 20 on the left, and under the limiting effect of the adjusting rod 21, the clamping plate 20 and the limiting wheel 23, the end face of the gypsum board comes into contact with the first grinding wheel of the transverse grinding mechanism 3. After grinding is completed, the gypsum board on the first conveyor mechanism 2 moves, thereby moving the gypsum board to the second conveyor mechanism 4. At this time, the gypsum board is limited by the pressure roller 12, and the electric telescopic rod 19 and the clamping plate 20 on the right limit the gypsum board on the second conveyor mechanism 4. At this time, the electric push rod 5 retracts and causes the connecting plate 6 to move towards the conveyor belt on the right, so that the second grinding wheel 8 contacts the two sides of the gypsum board. At the same time, the hydraulic rod 14 extends and causes the fixed frame 15 to move upward. At this time, the third grinding wheel corresponds to the other two sides of the gypsum board. Under the action of the second motor and the lead screw 16, the third grinding wheel realizes the moving grinding of the other two sides of the gypsum board, thereby improving the grinding effect.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
