Description

Technical Field

[0001] This utility model relates to the field of abrasion resistance testing technology for composite boards, and more specifically, it relates to an intumescent fireproof composite board abrasion resistance testing device. Background Technology

[0002] Intumescent fire-resistant composite panels are a high-performance building material primarily used to improve the fire resistance of buildings. When heated, these panels expand and form a heat-insulating carbonized layer, effectively preventing the spread of fire. After production and processing, intumescent fire-resistant composite panels require abrasion resistance testing to ensure their durability.

[0003] The patent document with publication number CN214952811U discloses an abrasion resistance testing device for composite panels, including a base, a motor, a test wheel, a connecting seat, a hinge, a fixing frame, a screw sleeve, an adjusting screw, a clamping plate, a handle, and a controller. The top of the base is fixedly connected to the motor, and the output end of the motor is provided with a drive shaft. The test wheel is fixedly mounted on the drive shaft through a fixing component. The base and the connecting seat are fixedly connected. The fixing frame and the connecting seat are hinged together by a hinge. The screw sleeve passes through the left end of the fixing frame. The adjusting screw is screwed through the screw sleeve. The left end of the clamping plate is provided with a threaded ring. The right end of the adjusting screw is rotatably mounted in the threaded ring. The left end of the adjusting screw is provided with a handle. The handle is fixedly connected to the top of the fixing frame. The controller is fixedly connected to the front end of the base. The test wheel and the controller are electrically connected.

[0004] However, the device lacks a debris collection component. Since the intumescent fireproof composite board generates a lot of debris during the abrasion resistance test, this debris will splash and contaminate the surrounding working environment. Secondly, during use, the worker needs to hold the handle and pull down the fixing frame to bring the composite board close to the test wheel, so that the test wheel can grind the composite board. The device cannot move the composite board automatically, which increases the workload of the workers and is very inconvenient to use. Utility Model Content

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] Please see Figures 1-5 An intumescent fireproof composite board abrasion resistance testing device includes an operating table 1, a protective shell 2 fixedly mounted on the operating table 1, a door 3 hinged to one side of the protective shell 2, a support base 4 fixedly mounted inside the protective shell 2, a first motor 5 fixedly mounted on the support base 4, a test wheel 6 mounted on the driving end of the first motor 5, a collection chamber 7 on the operating table 1, a discharge pipe 8 fixedly mounted at the lower end of the collection chamber 7, a toothed ring 9 rotatably mounted on the outer side of the discharge pipe 8, a second motor 10 fixedly mounted on the outer side of the discharge pipe 8, a gear 11 cooperating with the toothed ring 9 mounted on the driving end of the second motor 10, two connecting arms 12 mounted on the toothed ring 9, a scraper 13 fixedly mounted at the upper end of each connecting arm 12, and a collection box 14 movably mounted at the lower end of the discharge pipe 8.

[0031] In this embodiment, when it is necessary to protect and collect the debris generated during the abrasion resistance test of the intumescent fireproof composite board, the first motor 5 is started. The first motor 5 drives the test wheel 6 to rotate. The test wheel 6 contacts the intumescent fireproof composite board to conduct the abrasion resistance test. The generated debris is shielded by the protective shell 2 and the door 3 to prevent the debris from splashing into the surrounding environment. The debris falls into the collection chamber 7 and then enters the collection box 14 through the discharge pipe 8 for collection. The second motor 10 is started, and the second motor 10 drives the gear 11 to rotate. Since the gear 11 is meshed with the gear ring 9, the gear rotates around the rotating connection with the discharge pipe 8. The gear ring 9 drives the connecting arm 12 to rotate, and the connecting arm 12 drives the scraper 13 to rotate, so that the scraper 13 scrapes and cleans the waste debris adhering to the inside of the collection chamber 7 and the discharge pipe 8 and discharges it together.

[0032] Please see Figures 1-5 As an embodiment for automatically moving and testing intumescent fireproof composite panels that require abrasion resistance testing: A moving rod 15 is movably provided inside the protective shell 2. A fixed frame 16 is provided at one end of the moving rod 15. Two clamping plates 17 are movably provided inside the fixed frame 16. Two stops 18 are provided on one side of each clamping plate 17. A moving groove 19 is provided inside the fixed frame 16. A bidirectional lead screw 20 is rotatably provided inside the moving groove 19. A throttle 21 is fixedly provided at one end of the bidirectional lead screw 20 through the fixed frame 16. Two moving seats 22 are threaded onto the bidirectional lead screw 20. The upper ends of the two moving seats 22 are fixedly connected to the two clamping plates 17 respectively. A limiting shell 23 is fixedly provided on one side of the protective shell 2. A screw 24 is rotatably provided inside the limiting shell 23. One end of the moving rod 15 extends into the limiting shell 23 and is threadedly connected to the screw 24. A third motor 25 is fixedly provided on the outside of the limiting shell 23. The driving end of the third motor 25 extends into the limiting shell 23 and is fixedly connected to the screw 24.

[0033] Specifically, the intumescent fireproof composite board for wear resistance testing is placed between two clamping plates 17 within the fixed frame 16. The handle 21 is rotated, causing the bidirectional lead screw 20 to rotate. Since the bidirectional lead screw 20 has two threaded areas in opposite directions, the two moving seats 22 move in adjacent directions. The moving seats 22 move the clamping plates 17, so that the two clamping plates 17 cooperate to clamp and fix the composite board within the fixed frame 16. At the same time, the clamping plates 17 move the stop block 18, so that the stop block 18 blocks the outside of the composite board to prevent it from falling during the movement. The third motor 25 is started, and the third motor 25 drives the screw 24 to rotate. Since the screw 24 is threadedly connected to the moving rod 15, the moving rod 15 moves outward along the limiting shell 23. The moving rod 15 moves the fixed frame 16, and the fixed frame 16 moves the fixed composite board, so that the composite board moves to contact the test wheel 6.

[0034] Please see Figures 1-5 As one embodiment for placing the collection box 14: a protective cover 26 is fixedly provided on the discharge pipe 8, the lower end of the protective cover 26 is movably connected to the collection box 14, the lower end of the collection box 14 is provided with multiple rollers 27, the lower end of the operating table 1 is fixedly provided with four support legs 28, each of the four support legs 28 is fixedly connected with a base plate 29, the lower end of the collection box 14 is fixedly provided with two positioning plates 30, and the base plate 29 is fixedly provided with two limiting grooves 31 that cooperate with the rollers 27 and the positioning plates 30.

[0035] Specifically, the collection box 14 is pushed to rotate the roller 27, causing the roller 27 to move into the limiting groove 31. The positioning plate 30 positions the collection box 14. At this time, the collection box 14 moves to the lower end of the protective cover 26. When the discharge pipe 8 discharges the material, the waste will be blocked by the protective cover 26, so that all of it enters the collection box 14 and avoids spillage.

[0036] In summary, when using the overall equipment:

[0037] When the collection box 14 needs to be placed, push the collection box 14, and the roller 27 will rotate, causing the roller 27 to move into the limiting groove 31. The positioning plate 30 will position the collection box 14. At this time, the collection box 14 will move to the lower end of the protective cover 26. When the discharge pipe 8 discharges the material, the waste will be blocked by the protective cover 26, so that all of it will enter the collection box 14 and avoid spillage.

[0038] When it is necessary to fix and move the intumescent fireproof composite board, place the intumescent fireproof composite board for abrasion resistance testing between the two clamping plates 17 inside the fixed frame 16, turn the handle 21, the handle 21 drives the bidirectional lead screw 20 to rotate. Since the bidirectional lead screw 20 has two threaded areas in opposite directions, the two moving seats 22 move in adjacent directions. The moving seats 22 drive the clamping plates 17 to move, so that the two clamping plates 17 cooperate to clamp and fix the composite board inside the fixed frame 16. At the same time, the clamping plates 17 drive the stop block 18 to move, so that the stop block 18 blocks the outside of the composite board to prevent it from falling off during the movement. Start the third motor 25, the third motor 25 drives the screw 24 to rotate. Since the screw 24 is threadedly connected to the moving rod 15, the moving rod 15 moves outward along the limiting shell 23. The moving rod 15 drives the fixed frame 16 to move, the fixed frame 16 drives the fixed composite board to move, so that the composite board moves to contact the test wheel 6.

[0039] When waste debris needs to be collected during the abrasion resistance test, the first motor 5 is started. The first motor 5 drives the test wheel 6 to rotate. The test wheel 6 contacts the intumescent fireproof composite board to conduct the abrasion resistance test. The generated debris is shielded by the protective shell 2 and the door 3 to prevent the debris from splashing into the surrounding environment. The debris falls into the collection chamber 7 and then enters the collection box 14 through the discharge pipe 8 for collection. The second motor 10 is started, and the second motor 10 drives the gear 11 to rotate. Since the gear 11 is meshed with the gear ring 9, the gear rotates around the connection point with the discharge pipe 8. The gear ring 9 drives the connecting arm 12 to rotate, and the connecting arm 12 drives the scraper 13 to rotate, so that the scraper 13 scrapes and cleans the waste debris adhering to the inside of the collection chamber 7 and the discharge pipe 8 and discharges it together.

[0040] A controller is fixedly installed on the outside of the protective shell 2. Unless otherwise specified, all electrical components on the device are controlled by the controller. Since the device matched with the controller is a common device, its control principle and circuit connection are existing, well-known and mature technologies. Therefore, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
