Description

Technical Field

[0001] This invention relates to the field of building material grade cellulose ether testing technology, specifically a cellulose ether performance testing system for building materials. Background Technology

[0002] Cellulose ethers are a class of polymeric compounds with ether structures obtained from natural cellulose through an etherification reaction. Cellulose itself is the most abundant natural polymer material on Earth. By introducing different substituents into the molecular chain, various types of cellulose ethers can be synthesized. These compounds typically possess good water solubility, thickening properties, water retention, and solution stability, and are therefore widely used in multiple industries. According to application fields, cellulose ethers can be divided into building material grade, pharmaceutical grade, food grade, and daily chemical grade. Among them, building material grade cellulose ethers occupy the main market due to their excellent performance and high demand in building materials. They are widely used in building materials such as premixed mortar, PVC, latex paint, and putty, mainly playing the roles of thickening, water retention, retarding, and improving workability. They are key additives for improving the quality of building materials and the ease of construction.

[0003] To ensure that cellulose ethers can effectively perform the aforementioned functions in building materials, performance testing is essential. This process not only verifies whether the product quality meets standards but also directly reflects its performance in actual use. In the performance testing of cellulose ethers in building materials, consistency and anti-slip properties are the two most critical items. These two properties are interconnected and mutually influential. Consistency reflects the material's fluidity and ease of construction, while anti-slip properties reflect its stability on vertical construction surfaces. Both of these indicators are usually tested to comprehensively evaluate the actual performance of cellulose ethers in mortar.

[0004] However, existing testing methods have many shortcomings: First, consistency and anti-slip properties are often tested separately in two independent devices, which are not interconnected in operation. After one test is completed, the sample must be manually transferred to another device for further testing, which is cumbersome and inefficient. Second, each test is generally limited to evaluating a single cellulose ether sample, making it impossible to compare multiple samples under uniform conditions, which affects the representativeness and applicability of the data. Furthermore, the anti-slip property test still relies on manual operation, such as manually spreading the sample, placing the tiles and pressing them, which can easily lead to uneven sample thickness and improper tile adhesion, making it difficult to unify the various variables in the test, ultimately affecting the stability and accuracy of the results. Summary of the Invention

[0005] This invention provides a performance testing system for cellulose ethers in building materials, which solves the problems of existing performance testing methods for cellulose ethers in building materials, which require separate operations for consistency and anti-slip properties in two independent sets of equipment. These methods are cumbersome, inefficient, and often only test a single sample, lacking comparability and failing to reflect the performance differences of different samples under the same conditions. Furthermore, the anti-slip property test still relies heavily on manual operation, which can lead to uneven sample thickness and poor adhesion. The test variables are difficult to unify, which seriously affects the accuracy of the results.

[0006] This invention provides a cellulose ether performance testing system for building materials, comprising a testing platform with a sliding frame mounted on its upper surface. A fusion testing unit is jointly provided between the sliding frame and the testing platform for sequentially testing the consistency and anti-slip properties of the building material cellulose ether. The fusion testing unit includes a parallel testing mechanism mounted on the testing platform for simultaneously testing and comparing the consistency of multiple building material cellulose ether samples, a feeding mechanism slidably mounted on the left side of the sliding frame for equally dispensing the building material cellulose ether samples onto the parallel testing mechanism, and a feeding mechanism slidably mounted on the right side of the sliding frame for directly feeding the parallel testing mechanism. A sliding test mechanism for anti-slip properties of building material cellulose ether samples is provided. The sliding test mechanism includes a mounting base plate installed on a sliding frame and several mounting frames fixedly connected at equal intervals to the lower end face of the mounting base plate. An inclined push plate for evenly spreading the building material cellulose ether sample is fixedly connected to the left side between the front and rear opposite sides of the mounting frame. Several scraping comb teeth are fixedly connected at equal intervals to the lower part of the inclined push plate. A guide unit for guiding and laying standard ceramic tiles on the spread building material cellulose ether sample is provided in the middle of the mounting frame. A rolling unit for automatically compacting the laid standard ceramic tiles is provided in the right side of the mounting frame.

[0007] In one possible implementation, the parallel detection mechanism includes several bearing seats that are fixedly connected at equal intervals to the upper surface of the detection platform and several support rods that are slidably connected through the bearing seats. The upper ends of the support rods are all fixedly connected to a connecting plate for reciprocating up and down vibration. Several sliding rods are fixedly connected at equal intervals to the upper surface of the connecting plate. Each sliding rod has a placement platform hinged to its upper part through a lug. The sliding rod is provided with a support unit for supporting and limiting the placement platform.

[0008] In one possible implementation, the sliding frame includes two slide rail seats that are symmetrically fixed to the upper surface of the testing platform by means of a support column. Each slide rail seat is slidably connected to an electric slider, and each electric slider is fixedly connected to a support frame on its upper surface.

[0009] In one possible implementation, the feeding mechanism includes a storage box fixedly connected between two support frames and open at the top. Two bearing rings are symmetrically fixedly connected to the front and back of the lower end of the storage box. A rotating cylinder is rotatably connected between the two bearing rings. Several output pipes corresponding to the placement platform are equidistantly connected along the axial direction on the rotating cylinder. A strip-shaped through groove is opened on the outer wall of the rotating cylinder along its own axial direction. A strip-shaped discharge groove that cooperates with the strip-shaped through groove is opened at the bottom of the storage box cavity and directly above the rotating cylinder.

[0010] In one possible implementation, the guide unit includes a rectangular receiving frame fixedly connected between the front and rear opposite sides of the mounting frame, and an inclined guide plate fixedly connected between the front and rear opposite sides of the mounting frame and located on the left side of the rectangular receiving frame. The rectangular receiving frame has a C-shaped mounting groove. Two rotating shafts are symmetrically rotatably connected to the left wall of the C-shaped mounting groove. Baffles are fixedly connected to the outside of each rotating shaft. A gear ring is fixedly connected to the right side of the outer wall of the rotating shaft. A sliding plate is slidably connected through the right wall of the rectangular receiving frame. The sliding plate consists of two straight segments at different horizontal positions and staggered distribution, and an inclined segment fixedly connected between the two straight segments. A return spring is fixedly connected between the sliding plate and the C-shaped mounting groove. A rack that meshes with the gear ring is fixedly connected to each of the two straight segments of the sliding plate. The two racks are centrally symmetrically distributed.

[0011] In one possible implementation, the rolling unit includes sliding grooves formed on opposite sides of the mounting frame, each sliding groove having a sliding seat slidably connected thereto, a tension spring being fixedly connected between the sliding seat and the sliding groove, and a roller being fixedly connected between the two sliding seats.

[0012] In one possible implementation, the support unit includes an L-shaped support arm that is slidably connected to each sliding rod, and the upper part of the right end face of the sliding rod has an insertion groove into which the vertical section of the L-shaped support arm extends.

[0013] In one possible implementation, a limit spring is fixedly connected between the L-shaped support arm and the sliding rod, and a connecting rod is fixedly connected to the left end of the transverse section of the L-shaped support arm.

[0014] In one possible implementation, a pusher plate is symmetrically fixedly connected to the left end of the inclined pusher plate, and the left half of the pusher plate is a trumpet shape that gradually expands outward from right to left.

[0015] In one possible implementation, a fixing rod is fixedly connected between two adjacent sliding plates, and a pull ring is fixedly connected to the front side of the front sliding plate.

[0016] As can be seen from the above technical solutions, the present invention has the following advantages:

[0017] In this invention, the consistency of multiple building material cellulose ethers is simultaneously tested using equally spaced placement stages in a parallel testing mechanism. This allows for direct output of the consistency differences of each sample under the same benchmark, and facilitates lateral performance comparison and analysis after testing, thereby enhancing the reliability and comparability of the test results data.

[0018] In this invention, the inclined push plate, the guide paving unit, and the rolling unit in the sliding test mechanism work together to automate the entire process of building material cellulose ether samples from paving to tile bonding and compaction. This ensures consistent paving thickness, uniform tile bonding position, and controllable force application, guaranteeing uniformity of various variables in the test. It also facilitates the horizontal comparative analysis of multiple building material cellulose ether samples, thereby significantly reducing the test error rate and improving the reliability and accuracy of the entire testing process.

[0019] In this invention, the parallel detection mechanism and the sliding test mechanism in the integrated detection unit work together to achieve the sequential completion of consistency and anti-slip properties testing of cellulose ether samples of building materials at the same detection position. The test items are seamlessly connected, eliminating intermediate transfer and repeated preparation steps, making the detection process more compact, efficient, and continuous, significantly improving the overall detection efficiency. Furthermore, the two tests are completed continuously within the time window when the sample state is most stable, effectively maintaining the original performance of the sample and improving the timeliness and accuracy of the test results.

[0033] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Please see Figure 1 and Figure 2This invention provides a technical solution: a building material cellulose ether performance testing system, including a testing platform 1, a sliding frame 2 installed on the upper surface of the testing platform 1, and a fusion testing unit for sequentially testing the consistency and anti-slip properties of building material cellulose ethers between the sliding frame 2 and the testing platform 1. The fusion testing unit includes a parallel testing mechanism 3 installed on the testing platform 1 for simultaneously testing and comparing the consistency of multiple building material cellulose ether samples, a feeding mechanism 4 slidably installed on the left side of the sliding frame 2 for equally distributing building material cellulose ether samples onto the parallel testing mechanism 3, and a sliding testing mechanism 5 slidably installed on the right side of the sliding frame 2 for directly testing the anti-slip properties of the building material cellulose ether samples on the parallel testing mechanism 3. The sliding frame 2 includes two slide rail seats 21 symmetrically fixed to the upper surface of the testing platform 1 by support columns. Each slide rail seat 21 is slidably connected to an electric slider 22, and each electric slider 22 is fixedly connected to a support frame 23 on its upper surface.

[0035] Please see Figure 2 and Figure 9 In this embodiment, the parallel detection mechanism 3 includes several bearing seats 31 equidistantly fixedly connected to the upper surface of the detection table 1, and several support rods slidably connected to the bearing seats 31. The upper ends of the support rods are all fixedly connected to a connecting plate for reciprocating up-and-down vibration. Several sliding rods 32 are equidistantly fixedly connected to the upper surface of the connecting plate. Each sliding rod 32 has a placement platform 34 hinged to its upper part via a lug. A support unit 35 for supporting and limiting the placement platform 34 is provided on the sliding rod 32. The support unit 35 includes an L-shaped component slidably connected to each sliding rod 32. The upper part of the right end face of the L-shaped support arm 351 and the sliding rod 32 is provided with an insertion groove 352 for the vertical section of the L-shaped support arm 351 to extend into. The L-shaped support arm 351 and the sliding rod 32 are fixedly connected together with a limit spring. The left end of the horizontal section of the L-shaped support arm 351 is fixedly connected with a connecting rod. The lower end face of the placement platform 34 is fixedly connected with a limiting plate that fits against the left side of the sliding rod 32. The limiting plate is used to prevent the placement platform 34, which is in a horizontal position, from rotating counterclockwise. The vertical section of the L-shaped support arm 351 touches the right side of the lower end face of the placement platform 34 so that the placement platform 34 is initially in a horizontal position.

[0036] Please see Figure 2 and Figure 8 The feeding mechanism 4 includes a storage box 41 fixedly connected between two support frames 23 and open at the top. Two bearing rings 42 are symmetrically fixedly connected to the front and back of the lower end of the storage box 41. A rotating cylinder 43 is rotatably connected between the two bearing rings 42. Several output pipes 44 corresponding to the placement platform 34 are equidistantly connected along the axial direction on the rotating cylinder 43. A strip-shaped through groove 45 is opened on the outer wall of the rotating cylinder 43 along its own axial direction. A strip-shaped discharge groove 46 that cooperates with the strip-shaped through groove 45 is opened at the bottom of the storage box 41 and directly above the rotating cylinder 43.

[0037] The cellulose ether sample for building materials is poured into the storage box 41. Initially, the output pipe 44 is in a horizontal position, and the strip discharge trough 46 is blocked by the outer wall of the rotating drum 43. Then, the electric slider 22 is controlled to move along the slide rail 21, driving the support frame 23 to move. The support frame 23 drives the feeding mechanism 4 to move directly above the placement platform 34. Then, the rotating drum 43 is manually rotated 90 degrees counterclockwise. The rotating drum 43 then drives the output pipe 44 to rotate until the output pipe 44 becomes vertical. At this time, the strip discharge trough 45 is also driven by the rotating drum 43. The drum 43 is connected to the strip discharge trough 46. Then, the building material cellulose ether sample in the storage box 41 flows into the drum 43 and is then placed onto the placement platform 34 through the output pipe 44. When the required amount of building material cellulose ether sample is delivered to the placement platform 34, the drum 43 is manually rotated clockwise. The drum 43 then drives the output pipe 44 to rotate, so that the output pipe 44 rotates to the horizontal position. At the same time, the strip passage 45 and the strip discharge trough 46 are misaligned, thereby ensuring that the amount of building material cellulose ether sample on the placement platform 34 is the same.

[0038] The electric slider 22 is controlled again to move the feeding mechanism 4 away from the top of the placement platform 34 along the slide rail 21. Then, the connecting plate is driven to vibrate up and down by the external reciprocating drive device. The connecting plate then drives the placement platform 34 to move up and down through the sliding rod 32. After the placement platform 34 vibrates up and down a certain number of times, it stops. The maximum diameter of the building material cellulose ether sample (i.e., mortar) after vibration and the vertical diameter are measured with a ruler or distance sensor. The average value is taken as the consistency. The consistency of the building material cellulose ether sample can be accurately detected by comparing the flow and spreading distance of the building material cellulose ether sample on each placement platform 34.

[0039] It should be noted that when using a distance sensor for measurement, vertical positioning plates need to be set at the edge after the mortar has flowed and spread. The distance sensor is fixed on the positioning plates, and the emitted signal passes through the center of the spread mortar and is then reflected back by other positioning plates. The maximum diameter and vertical diameter of the mortar after vibration are calculated by the time it takes for the signal to travel from transmission to reception and the speed of signal transmission (such as the speed of infrared light or the speed of ultrasonic waves). The diameter measurement by the distance sensor is more accurate than the diameter measurement by observing a ruler with the human eye.

[0040] It should be noted that the external reciprocating drive device can be an existing vibration device or a G-shaped cam driven by a motor. The cam is located directly below the connecting plate. When the G-shaped cam rotates, it touches the lower end face of the connecting plate and pushes the connecting plate upward. When the G-shaped cam rotates to the point where its notch contacts the lower part of the connecting plate, the connecting plate moves downward rapidly under its own weight and hits the notch surface of the G-shaped cam, thus vibrating the connecting plate. Then the G-shaped cam pushes the connecting plate upward again, and the above steps are repeated to complete the vibration process.

[0041] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the sliding test mechanism 5 includes a mounting base plate 51 fixedly connected between two support frames 23 and several mounting frames 52 fixedly connected at equal intervals to the lower end surface of the mounting base plate 51. An inclined push plate 53 for evenly spreading the building material cellulose ether sample is fixedly connected to the left side between the front and rear opposite sides of the mounting frame 52. Several scraping comb teeth 54 are fixedly connected at equal intervals to the lower part of the inclined push plate 53. A guide laying unit 55 for guiding the standard ceramic tile and laying it on the spread building material cellulose ether sample is provided in the middle of the mounting frame 52. A rolling unit 56 for automatically compacting the laid standard ceramic tile is provided on the right side of the mounting frame 52. A push plate 6 is symmetrically fixedly connected to the front and rear of the left end of the inclined push plate 53. The left half of the push plate 6 is a trumpet shape that gradually expands outward from right to left.

[0042] Please see Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 10 The guide unit 55 includes a rectangular receiving frame 551 fixedly connected between the front and rear opposite sides of the mounting frame 52, and an inclined guide plate 552 fixedly connected between the front and rear opposite sides of the mounting frame 52 and located on the left side of the rectangular receiving frame 551. A C-shaped mounting groove 553 is provided on the rectangular receiving frame 551. Two rotating shafts 554 are symmetrically rotatably connected to the left wall of the C-shaped mounting groove 553. Each rotating shaft 554 is fixedly connected to a baffle 555. A gear ring 556 is fixedly connected to the right side of the outer wall of the rotating shaft 554. A through-hole is formed on the right wall of the rectangular receiving frame 551. The sliding connection includes a sliding plate 557, which consists of two straight segments at different horizontal positions and staggered distribution, and an inclined segment fixedly connected between the two straight segments. A return spring is fixedly connected between the sliding plate 557 and the C-shaped mounting groove 553. A rack 558 that meshes with the gear ring 556 is fixedly connected to each of the two straight segments of the sliding plate 557. The two racks 558 are centrally symmetrically distributed. A fixing rod is fixedly connected between two adjacent sliding plates 557. A pull ring is fixedly connected to the front side of the sliding plate 557 located at the front.

[0043] Please see Figure 4 and Figure 5 The rolling unit 56 includes sliding grooves 561 on opposite sides of the mounting frame 52. Each sliding groove 561 is slidably connected to a sliding seat 562. A tension spring is fixedly connected between the sliding seat 562 and the sliding groove 561. A roller 563 is fixedly connected between the two sliding seats 562.

[0044] The standard tile used for anti-slip testing is placed on the inclined guide plate 552. The first standard tile from the right after placement slides to the right into the rectangular receiving frame 551 under the action of the inclined surface of the inclined guide plate 552 (the two baffles 555 in the rectangular receiving frame 551 are initially in a horizontally opposite state), and then is placed flat on the two baffles 555.

[0045] The electric slider 22 drives the support frame 23 to move gradually to the left along the slide rail seat 21. The support frame 23 then drives the mounting frame 52 to move. The mounting frame 52 then drives the inclined push plate 53 to pass over the placement platform 34 from right to left. The inclined push plate 53 gradually spreads and flattens the building material cellulose ether sample to the left. Then, the scraper comb 54 is used to scratch several grooves on the surface of the spread building material cellulose ether sample to simulate the texture of mortar applied to the wall during actual tile installation.

[0046] Next, the support frame 23, through the mounting base plate 51, moves the rectangular receiving frame 551 to directly above the unfolded building material cellulose ether sample. At this point, manually pulling the pull ring moves the first sliding plate 557. The sliding plate 557 then moves the remaining sliding plates 557 synchronously through the fixing rod. The sliding plate 557 then moves the rack 558 forward, and the rack 558 then rotates the gear ring 556, causing the two gear rings 556 located in the C-shaped mounting groove 553 to rotate downwards in opposite directions. 56 then drives the rotating shaft 554 to rotate, which in turn drives the baffle 555 to rotate, causing both baffles 555 to rotate downwards to a vertical position. Finally, the standard ceramic tile on the baffle 555 falls down from the rectangular receiving frame 551 onto the building material cellulose ether sample. Then the pull ring is released, and the reset spring resets and drives the sliding plate 557 to move backwards. The sliding plate 557 then drives the rack 558 to move synchronously. The rack 558 then cooperates with the gear to indirectly drive the baffle 555 to reverse and reset to a horizontal position.

[0047] Then, the mounting frame 52 moves the roller 563 to the left, contacting the upper surface of the standard tile laid on the building material cellulose ether sample (the lower edge of the roller 563 in the initial position is slightly lower than the upper surface of the standard tile after laying). Then, the tension spring pulls the sliding seat 562 down, and the sliding seat 562 transmits the downward pressure to the roller 563. The roller 563 then presses the standard tile down, pressing the tile firmly onto the building material cellulose ether sample. When the rectangular receiving frame 551 moves to the left to the next empty space on the laid building material cellulose ether sample, the above steps of pulling the ring forward can be repeated again, and the two corresponding baffles 555 rotate downward again so that the next standard tile can be laid on the building material cellulose ether sample.

[0048] When the roller 563 moves to the left and moves away from the area directly above the placement platform 34, the connecting rod is first pulled to the left to move the L-shaped support arm 351 until the vertical section of the L-shaped support arm 351 finally slides into the insertion groove 352. At this time, the vertical section of the L-shaped support arm 351 loses its support for the lower side of the placement platform 34. Then, the placement platform 34 rotates clockwise around the hinge point with the sliding rod 32 under its own weight until it becomes vertical. After standing still for a period of time, the vertical distance of the standard ceramic tile sliding down is measured with a ruler or distance sensor to determine whether the anti-slip property of the building material cellulose ether sample is within the qualified range.

[0049] After the test is completed, manually push the L-shaped support arm 351 to the right and then lift the placement table 34 to rotate counterclockwise, so that the vertical section of the L-shaped support arm 351 touches the right side of the lower end face of the placement table 34 again. At the same time, control the electric slider 22 to drive the support frame 23 to move to the right. The support frame 23 then drives the sliding test mechanism 5 and the feeding mechanism 4 to move to the right and reset to the initial position.

[0050] During operation, the building material cellulose ether sample is first placed into the feeding mechanism 4. Then, the electric slider 22 is controlled to move the support frame 23 to the left. The support frame 23 then moves the feeding unit directly above the parallel detection mechanism 3. The feeding mechanism 4 then delivers the building material cellulose ether sample onto the placement platform 34 in the parallel detection mechanism 3. Subsequently, the electric slider 22 moves the feeding mechanism 4 away from the parallel detection mechanism 3. The parallel detection mechanism 3 is then controlled to perform consistency testing on the building material cellulose ether sample. After the consistency test is completed, the electric slider 22 is again controlled to indirectly... The sliding test mechanism 5 is moved to the left. During the leftward movement, the inclined push plate 53 inside the sliding test mechanism 5 evenly spreads the building material cellulose ether sample after consistency testing onto the placement platform 34. The guide unit 55 then lays the standard ceramic tile onto the spread-out placement platform 34. The rolling unit 56 compacts the laid-out standard ceramic tile. Finally, by controlling the support unit 35 to release the limit on the placement platform 34, the placement platform 34 is rotated clockwise to become vertical. After letting it stand for a period of time, the downward movement distance of the ceramic tile is measured, and the anti-slip property of the building material cellulose ether sample can be detected.
