Description

Technical Field

[0001] This invention relates to the field of gypsum board testing technology, and in particular to an impact testing device for impact-resistant paper-faced gypsum board. Background Technology

[0002] Paper-faced gypsum board is a type of board made from building gypsum as the main raw material, with appropriate additives and fibers mixed in as the core, and special paper as the facing. Paper-faced gypsum board is characterized by its light weight, sound insulation, heat insulation, strong processing performance, and simple construction method. Paper-faced gypsum board can be divided into four categories: ordinary, water-resistant, fire-resistant, and moisture-proof.

[0003] After gypsum board is manufactured, its strength needs to be tested. Currently available testing devices typically require manual placement of the gypsum board on the testing device, followed by testing, and then manual removal. This process is time-consuming, labor-intensive, and inefficient. Therefore, we propose an impact testing device for impact-resistant paper-faced gypsum board. Summary of the Invention

A mounting groove is opened above the position of the squeeze roller on the front side wall of the base. A squeeze plate is movably installed inside the mounting groove. The top wall of the squeeze plate is in contact with the top wall inside the conveyor belt. A squeeze spring is fixedly installed between the rear side of the top wall of the squeeze plate and the mounting groove. An impact roller is fixedly installed on the mounting shaft above. Four squeeze auxiliary rollers are embedded in a ring evenly distributed on the arc-shaped side wall of the impact roller.

[0006] Preferably, the front side wall of the base is provided with an adjustment groove, an adjustment block is movably installed inside the adjustment groove, an upper mounting shaft is embedded in the adjustment block, and an adjustment bearing is embedded in the top wall of the adjustment block.

[0007] Preferably, an adjusting shaft is fixedly installed on the inner ring of the adjusting bearing, and the top wall of the adjusting shaft extends through the top wall of the base, so that the adjusting shaft and the base are threadedly connected.

[0008] Preferably, a rotating plate is fixedly installed on the top wall of the adjusting shaft, the bottom wall of the rotating plate is in contact with the top wall of the base, and a handle is fixedly installed on the top wall of the rotating plate.

[0009] Preferably, an installation screw is fixedly installed on the rear side wall inside the impact roller. The installation screw is a cylindrical structure with threads on the side wall, and an extrusion block is movably installed on the front side wall of the impact roller.

[0010] Preferably, the extrusion block gradually decreases in size from front to back, and the rear side wall of the extrusion block is provided with a threaded groove that matches the mounting screw.

[0011] Preferably, a placement groove is provided in the middle of the outer wall of the conveyor belt, and the placement groove is an annular groove adapted to the conveyor belt.

[0012] Preferably, a collection box is fixedly installed on the left side wall of the base, and a feeding plate is fixedly installed on the right side of the top wall of the collection box. The feeding plate is a rectangular plate with a triangular cross-section. The upper right side wall of the feeding plate is in contact with the outer wall of the conveyor belt. A movable shaft is movably installed on the left side inside the collection box, and a sealing plate is sleeved on the movable shaft.

[0013] Preferably, the bottom wall of the sealing plate is curved, and a limiting groove is provided on the upper left side of the front wall of the base corresponding to the position of the sealing plate. The limiting groove extends backward through the front and rear side walls of the collection box and the front and rear side walls of the sealing plate, and a detachable limiting rod is movably installed in the limiting groove.

[0014] Beneficial effects This invention provides an impact testing device for impact-resistant gypsum board. It has the following advantages: (1) The impact testing device for impact-resistant gypsum board uses an external feeding device to transport the produced gypsum board onto a conveyor belt. The conveyor belt is sleeved on the mounting roller, which is fixedly mounted on the mounting shaft. A drive motor connected to the mounting shaft is mounted on the base. Starting the drive motor causes the mounting shaft to rotate, which in turn rotates the conveyor belt to transport the gypsum board. Simultaneously, starting the lower drive motor causes the lower mounting shaft to rotate, which in turn rotates the extrusion roller. An installation groove is provided on the base, and an extrusion plate is movably mounted in the groove via an extrusion spring. The extrusion plate is located above the extrusion roller and fits against the upper interior of the conveyor belt. The pressure roller has a special structure. When the pressure roller rotates, it continuously presses the pressure plate upwards, causing the pressure plate to move upwards inside the mounting groove and press the pressure spring. At the same time, the drive motor located above is activated, which causes the mounting shaft located above to rotate. The mounting shaft drives the impact roller to rotate, and the impact roller is embedded with a secondary pressure roller. When the gypsum board moves between the impact roller and the pressure plate, the secondary pressure roller on the impact roller and the pressure plate will squeeze and impact the gypsum board, thereby testing the strength of the gypsum board. Since the conveyor belt continuously transports the gypsum board, and the pressure plate and the secondary pressure roller are also constantly moving, the effect of rapid and uninterrupted testing of gypsum board is achieved, improving the efficiency of gypsum board testing.

[0015] (2) The impact testing device for impact-resistant gypsum board has an installation screw fixedly installed inside the impact roller and an extrusion block movably installed on the front side of the impact roller. The extrusion block gradually decreases in size from front to back. The extrusion block and the installation screw are connected by a thread. Rotating the extrusion block causes it to move towards the impact roller on the installation screw. Since the extrusion block gradually decreases in size from front to back, it will extrude the extrusion auxiliary roller during the process of moving towards the impact roller, causing the extrusion auxiliary roller to move outward. This reduces the distance between the extrusion auxiliary roller and the conveyor belt, increasing the extrusion strength on the gypsum board and achieving the effect of adjustable extrusion strength on the gypsum board.

[0016] (3) The impact testing device for impact-resistant gypsum board has a drive motor and mounting shaft mounted on the upper part of the adjustment block, and the adjustment block is movably mounted inside the adjustment groove. The adjustment shaft is movably mounted on the adjustment block through the adjustment bearing. The top of the adjustment shaft passes through the base and is threadedly connected to the base. A rotating plate and a handle are also fixedly mounted on the adjustment shaft. When the handle is held and rotated, the handle will drive the rotating plate to rotate, and the rotating plate will drive the adjustment shaft to rotate. Since the adjustment shaft is threadedly connected to the base, the rotation of the adjustment shaft will cause the adjustment block to move inside the adjustment groove, thereby driving the impact roller and the extrusion roller to move upward, so that the extrusion roller will not extrude the gypsum board, thus achieving the effect of normal transportation of gypsum board when not testing.

[0017] (4) The impact testing device for impact-resistant paper-faced gypsum board has a collection box fixedly installed on the left side of the base, and a feeding plate installed on the collection box. The upper right side wall of the feeding plate is attached to the outer side wall of the conveyor belt, and a placement groove is opened on the conveyor belt. The placement groove can limit the gypsum board and prevent the gypsum board from moving around on the conveyor belt. After the gypsum board is tested, it will fall into the inside of the collection box along the inclined surface of the feeding plate, thereby achieving the effect of guiding and collecting the gypsum board after the test is completed.

[0018] (5) The impact testing device for impact-resistant paper-faced gypsum board has a sealing plate movably installed on the collection box via a movable shaft. The sealing plate is penetrated by a limiting groove, and a limiting rod is movably installed in the limiting groove. When the limiting rod is removed from the limiting groove, the sealing plate can be flipped to the left. At this time, the gypsum board inside the collection box can be taken out from the inside of the collection box, thereby achieving the effect of facilitating material removal.

[0027] A placement groove 21 is provided in the middle of the outer wall of the conveyor belt 6. The placement groove 21 is an annular groove adapted to the conveyor belt 6.

[0028] A collection box 22 is fixedly installed on the left side wall of the base 1. The collection box 22 is a hollow rectangular structure. A feeding plate 23 is fixedly installed on the right side of the top wall of the collection box 22. The feeding plate 23 is a rectangular plate with a triangular cross-section.

A detachable limiting rod 27 is movably installed in the limiting groove 26. The limiting rod 27 is a cylindrical structure.

[0029] Working principle of the invention: In use, the produced gypsum boards are conveyed onto the conveyor belt 6 via an external feeding device. The conveyor belt 6 is fitted onto the mounting roller 5, which is fixedly mounted on the mounting shaft 3. A drive motor 4 connected to the mounting shaft 3 is mounted on the base 1. Starting the drive motor 4 causes the mounting shaft 3 to rotate, which in turn rotates the conveyor belt 6 to transport the gypsum boards. Simultaneously, starting the lower drive motor 4 rotates the lower mounting shaft 3, which in turn rotates the extrusion roller 7. The base 1 has an installation groove 8, within which an extrusion plate 9 is movably mounted via an extrusion spring 10. The extrusion plate 9 is located above the extrusion roller 7 and fits against the upper interior of the conveyor belt 6. Due to the special structure of the extrusion roller 7, when… When the extrusion roller 7 rotates, it continuously presses the extrusion plate 9 upwards, causing the extrusion plate 9 to move upwards inside the mounting groove 8 and press the extrusion spring 10. At the same time, the drive motor 4 located above is activated, causing the mounting shaft 3 located above to rotate. The mounting shaft 3 drives the impact roller 11 to rotate, and the impact roller 11 is inlaid with an extrusion auxiliary roller 12. When the gypsum board moves between the impact roller 11 and the extrusion plate 9, the extrusion auxiliary roller 12 on the impact roller 11 and the extrusion plate 9 will squeeze and impact the gypsum board, thereby testing the strength of the gypsum board. Since the conveyor belt 6 continuously transports the gypsum board, and the extrusion plate 9 and the extrusion auxiliary roller 12 are also constantly moving, the effect of rapid and uninterrupted testing of the gypsum board is achieved, improving the efficiency of gypsum board testing.

[0030] Since the mounting screw 19 is fixedly installed inside the impact roller 11, and the extrusion block 20 is movably installed on the front side of the impact roller 11, and the extrusion block 20 gradually decreases in size from front to back, the extrusion block 20 is also connected to the mounting screw 19 by a thread. Rotating the extrusion block 20 causes the extrusion block 20 to move towards the impact roller 11 on the mounting screw 19. Since the extrusion block 20 gradually decreases in size from front to back, it will extrude the extrusion auxiliary roller 12 during the process of moving into the impact roller 11, causing the extrusion auxiliary roller 12 to move outward. This reduces the distance between the extrusion auxiliary roller 12 and the conveyor belt 6, increasing the extrusion intensity on the gypsum board and achieving the effect of adjustable extrusion intensity on the gypsum board.

[0031] Since the drive motor 4 and mounting shaft 3 located above are embedded in the adjusting block 14, and the adjusting block 14 is movably installed inside the adjusting groove 13, the adjusting shaft 16 is movably installed on the adjusting block 14 through the adjusting bearing 15. The top of the adjusting shaft 16 passes through the base 1 and is threadedly connected to the base 1. The adjusting shaft 16 is also fixedly installed with a rotating plate 17 and a handle 18. When the handle 18 is held and rotated, the handle 18 will drive the rotating plate 17 to rotate, and the rotating plate 17 will drive the adjusting shaft 16 to rotate. Since the adjusting shaft 16 is threadedly connected to the base 1, the rotation of the adjusting shaft 16 will cause the adjusting block 14 to move inside the adjusting groove 13, thereby driving the impact roller 11 and the extrusion auxiliary roller 12 to move upward, so that the extrusion auxiliary roller 12 will not extrude the gypsum board, thus achieving the effect of normal transportation of gypsum board when not being tested.

[0032] Since a collection box 22 is fixedly installed on the left side of the base 1, and a feeding plate 23 is installed on the collection box 22, the upper right side wall of the feeding plate 23 is in contact with the outer side wall of the conveyor belt 6, and a placement groove 21 is provided on the conveyor belt 6. The placement groove 21 can limit the position of the gypsum board and prevent the gypsum board from moving around on the conveyor belt 6. After the gypsum board is tested, it will fall into the inside of the collection box 22 along the inclined surface of the feeding plate 23, thereby achieving the effect of guiding and collecting the gypsum board after the test is completed.

[0033] A sealing plate 25 is movably mounted on the collection box 22 via a movable shaft 24. The sealing plate 25 is penetrated by a limiting groove 26. A limiting rod 27 is movably mounted in the limiting groove 26. By removing the limiting rod 27 from the limiting groove 26, the sealing plate 25 can be flipped to the left. At this time, the gypsum board inside the collection box 22 can be removed from the inside of the collection box 22, thereby achieving the effect of facilitating material retrieval.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
