Description

Technical Field

[0001] This invention relates to the field of testing technology for new concrete bricklaying materials, specifically to a pressure plate adjustable device for testing the compressive strength of new concrete bricklaying materials. Background Technology

[0002] Concrete bricklaying is a common building material. It is made from cement, sand, and stone as main raw materials, processed through mixing with water, molding, and curing to produce block-shaped building materials of specific shapes and sizes. Used in construction projects such as wall building, embankment construction, and floor paving, it possesses high compressive strength and durability, capable of withstanding significant loads and meeting the requirements of various building structures. The compressive strength of finished concrete bricklaying is a key indicator of its quality. Testing can directly determine whether the bricklaying meets the strength grade required by design and specifications. For example, conducting compressive strength tests on different batches of bricklaying during production can promptly identify substandard products, preventing the use of inferior bricks in construction projects and thus ensuring the overall quality of building materials.

[0003] The new concrete brick masonry compressive strength testing equipment applies uniform pressure to the concrete brick masonry through hydraulic or mechanical devices until the specimen breaks. The compressive strength is calculated based on the pressure value and the pressure area of ​​the specimen. However, when testing the compressive strength of finished concrete brick masonry, the unevenness and surface shape of the finished concrete brick masonry, as well as the unevenness of the surface of ordinary pressure plates, can lead to uneven pressure distribution and thus deviations in the test results.

[0015] This invention provides a compressive strength testing device for new concrete bricklaying materials with adjustable pressure plates. It has the following beneficial effects:

[0016] 1. This adjustable pressure plate concrete brick masonry compressive strength testing equipment is equipped with moving parts. Multiple pressure plate mechanisms are installed within the inner cavity of the fixed outer shell, dividing the pressure plate mechanism into several small blocks. Each small block can be independently adjusted in height. By adjusting the height of these small blocks, the pressure plate mechanism can better fit the surface of the brick, achieving sufficient contact and compression. Therefore, unlike ordinary pressure plates, it eliminates the need for frequent manual adjustments of the pressure plate position or the addition of shims and other auxiliary tools to adapt to different brick shapes and sizes. The fitting process can be completed quickly and automatically, saving test preparation time and improving overall testing efficiency.

[0017] 2. This adjustable pressure plate concrete new material brick masonry compressive strength testing equipment is equipped with a pressure plate mechanism. Pressure sensors are distributed at the bottom of the moving frame to monitor the pressure distribution between the pressure block and the brick in real time, providing data support for subsequent pressure adjustment. This ensures that the pressure block contacts the brick in the appropriate position and applies pressure, guaranteeing that the pressure is evenly distributed on the brick surface and avoiding inaccurate test results due to positional deviation. The pressure sensors can measure the pressure between the pressure block and the brick in real time.

[0018] 3. This adjustable pressure plate concrete brick masonry compressive strength testing device is equipped with a connecting component. The connecting component is located on the side of the pressure block. When the connecting frame drives the pressure sensor to press against the brick surface, and the pressure applied exceeds the tensile force of the first spring, the moving frame slides on the connecting sleeve via a sliding sleeve. This allows the moving frame to slide within the pressure block, preventing pressure sensor and bottom damage from compression. It also provides some protection for the brick masonry, preventing premature cracking or damage due to excessive or uneven pressure. The protective effect is particularly pronounced for bricks with low strength or high brittleness.

[0019] 4. This adjustable-plate concrete brick masonry compressive strength testing equipment is equipped with a cleaning component. After the compressive strength test of the brick masonry is completed, the fixed housing is moved upward by the output end of the transmission component. Then, by activating the drive mechanism, the telescopic rod of the drive mechanism drives the cleaning roller through the connecting block to move to the bottom of the fixed housing. This allows the cleaning roller to clean the bottom of the pressure block, the moving frame, and the pressure sensor, thus preventing a large amount of residual debris and dust from adhering to the bottom of the pressure block, the moving frame, and the pressure sensor after the compressive strength test, which would interfere with subsequent testing.

[0020] 5. This adjustable-plate concrete bricklaying compressive strength testing equipment is equipped with a contact mechanism. Two large triangular plates and one small triangular plate are positioned on the side of the contact frame near the baffle plate. This allows the large and small triangular plates to clean the top of the placement plate as the contact frame moves across it. The triangular plates, with their angled shapes and edges, achieve a deeper cleaning effect compared to flat cleaning tools, ensuring the cleanliness of the placement plate and removing debris. This prevents debris from affecting the flatness of the contact between the brick and the placement plate, ensuring the brick is placed stably. This allows the brick to be evenly stressed during compressive strength testing, improving the accuracy of the test results. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-6 The present invention provides a technical solution: a pressure plate adjustable concrete new material brick masonry compressive strength testing device.

[0036] Please see Figures 1-6 The present invention provides a technical solution comprising:

[0037] The main body 1 has a control component 2 fixedly connected to its side, a transmission component 4 fixedly connected to its top, a fixing component 6 fixedly connected to the bottom of its inner cavity, and a cleaning component 7 fixedly connected to its inner side.

[0038] The moving part 5 is used to perform strength extrusion work on the finished concrete bricks. The top of the moving part 5 is fixedly connected to the output end of the transmission part 4, and the side of the moving part 5 is slidably connected to the inner side of the main body 1.

[0039] Please see Figure 4 The moving part 5 includes a fixed housing 51. The top of the fixed housing 51 is fixedly connected to the output end of the transmission part 4. The side of the fixed housing 51 is slidably connected to the inner side of the main body 1. The inner side of the fixed housing 51 is uniformly provided with pressure plate mechanisms 53. The bottom of the fixed housing 51 is fixedly connected to a connecting frame 52. The bottom of the connecting frame 52 is fixedly connected to a connecting frame 54 by a fixing bolt. When the concrete finished brickwork is being tested for strength, the output end of the transmission part 4 drives the fixed housing 51 to move downward, thereby causing the fixed housing 51 to drive the connecting frame 54 to move downward through the connecting frame 52, so that the pressure plate mechanism 53 abuts against the top of the concrete brickwork placed on the fixed part 6.

[0040] Please see Figure 5The pressure plate mechanism 53 includes a square plate 531. A drive assembly 532 is fixedly connected to the side of the square plate 531. The bottom of the drive assembly 532 is fixedly connected to the bottom of the inner cavity of the fixed housing 51. A moving rod 533 is fixedly connected to the output end of the drive assembly 532. The side of the moving rod 533 is slidably connected to the inner side of the connecting frame 52 and the connecting frame 54. A pressure block 534 is fixedly connected to the end of the moving rod 533 away from the drive assembly 532. A moving frame 535 is slidably connected to the inner side of the pressure block 534. A pressure sensor 536 is fixedly connected to the side of the moving frame 535 away from the pressure block 534. A connecting component 537 is fixedly connected to the side away from the pressure sensor 536, and the other end of the connecting component 537 is fixedly connected to the inner side of the pressure block 534. During the detection process, the pressure sensor 536 can accurately capture pressure changes and convert the pressure signal into a processable signal form such as an electrical signal, and send a command to the drive component 532. When the drive component 532 receives the command from the pressure sensor 536, the output end of the drive component 532 drives the pressure block 534 to move downward through the moving rod 533, so that the pressure block 534 can better fit the surface of the brick and achieve full contact compression.

[0041] Please see Figure 6 The connecting assembly 537 includes a connecting sleeve 5371, the side of which is fixedly connected to the inner side of the pressure block 534. A sliding sleeve 5372 is slidably connected to the side of the connecting sleeve 5371. The other side of the sliding sleeve 5372 is fixedly connected to the side of the moving frame 535 away from the pressure sensor 536. A first spring 5373 is sleeved on the connecting sleeve 5371. One end of the first spring 5373 is fixedly connected to the sliding sleeve 5372, and the other end of the first spring 5373 is fixedly connected to the connecting sleeve 5371. By providing the connecting assembly 537 in the side of the pressure block 534, the connecting frame 52 drives the pressure sensor 536. When the pressure is applied to the surface of the brickwork, if the compressive force on the movable frame 535 is greater than the tensile force of the first spring 5373, the movable frame 535 will slide on the connecting sleeve 5371 through the sliding sleeve 5372. This allows the movable frame 535 to slide inside the pressure block 534, thus avoiding compressive damage to the pressure sensor 536 and the bottom of the movable frame 535. At the same time, it can provide a certain degree of protection for the brickwork, preventing premature cracking or damage caused by excessive or uneven pressure. The protective effect is more obvious for some brickwork with low strength or high brittleness.

[0042] Please see Figure 7 The present invention provides a technical solution:

[0043] The cleaning component 7 includes a cleaning housing 71, the side of which is fixedly connected to the inside of the main body 1. A mesh plate 72 is fixedly connected to the inside of the cleaning housing 71. A rotating rod 73 is rotatably connected to the inside of the cleaning housing 71. Cleaning rods 74 are evenly arranged on the side of the rotating rod 73, and the cleaning rods 74 are positioned above the mesh plate 72. A drive mechanism 75 is fixedly connected to both sides of the inner cavity of the cleaning housing 71. A telescopic rod 76 is fixedly connected to the output end of the drive mechanism 75. A connecting block 77 is fixedly connected to the end of the telescopic rod 76 away from the drive mechanism 75. Cleaning rollers 78 are rotatably connected to the inner sides of the two connecting blocks 77. There are two cleaning rollers 78. When cleaning... After the bricklaying compressive strength test is completed, the fixed housing 51 is moved upward by the output end of the transmission component 4. Then, the drive mechanism 75 is activated. The telescopic rod 76 of the drive mechanism 75 drives the cleaning roller 78 through the connecting block 77 to move to the bottom of the fixed housing 51. This allows the cleaning roller 78 to clean the bottom of the pressure block 534, the moving frame 535, and the pressure sensor 536. This avoids the phenomenon that a large amount of residual debris and dust will adhere to the bottom of the pressure block 534, the moving frame 535, and the pressure sensor 536 after the bricklaying compressive strength test, which would interfere with subsequent testing.

[0044] After the cleaning roller 78 finishes cleaning, the output end of the drive mechanism 75 moves into the inner cavity of the cleaning housing 71 via the telescopic rod 76 and the connecting block 77. At the same time, because the rotating rod 73 and the cleaning rod 74 are provided on the inner side of the cleaning housing 71, when the cleaning roller 78 enters the cleaning housing 71, the cleaning roller 78 rotates against the side of the cleaning rod 74, so that the cleaning rod 74 cleans the side of the cleaning roller 78. This avoids excessive impurities on the cleaning roller 78 during subsequent cleaning, which would interfere with the cleaning work. At the same time, the impurities that fall off the surface of the cleaning roller 78 can enter the inner cavity of the cleaning housing 71 through the mesh plate 72 for collection.

[0045] Please see Figures 8-12 The present invention provides a technical solution:

[0046] Please see Figure 8The fixing component 6 includes a placement plate 61, with a limiting mechanism 62 fixedly connected to the top of the placement plate 61 and a collection mechanism 63 fixedly connected to the bottom of the placement plate 61. The side of the collection mechanism 63 is fixedly connected to the bottom of the inner cavity of the main body 1. When the compressive strength of the brick is tested, the brick is placed stably on the placement plate 61, and the limiting mechanisms 62 on both sides clamp and limit the two sides of the brick, thereby ensuring that the center of the brick is aligned with the center of the moving component 5. When the output end of the transmission component 4 drives the moving component 5 to perform the compression test on the brick on the placement plate 61, the broken concrete brick fragments can be collected by opening the collection mechanism 63.

[0047] Please see Figure 9 The limiting mechanism 62 includes two limiting rods 621 and a sliding frame 625. An upper limiting block 622 is fixedly connected to the top of each limiting rod 621 and is fixedly connected to the side of the fixed housing 51. A lower limiting block 623 is slidably connected to the side of the limiting rod 621 away from the upper limiting block 622. The side of the lower limiting block 623 is fixedly connected to the inner side of the main body 1. A connecting rod 624 is rotatably connected to the bottom of the limiting rod 621. The side of the sliding frame 625 is slidably connected to the inner side of the placement plate 61. One end of the connecting rod 624 away from the limiting rod 621 is rotatably connected to the inner side of the sliding frame 625. A contact mechanism 626 is fixedly connected to the side of the sliding frame 625 away from the placement plate 61. The bottom of the contact mechanism 626 is slidably connected to the top of the placement plate 61. A third spring 628 is sleeved on the sliding frame 625, and one end of the third spring 628 is connected to the placement plate 625. The inner side of the plate 61 is fixedly connected, and the other end of the third spring 628 is fixedly connected to the side of the sliding frame 625. The bottom of the plate 61 is fixedly connected to the placement frame 627. When the output end of the transmission component 4 drives the fixed housing 51 to move towards the bricks on the placement plate 61, the fixed housing 51 drives the upper limit block 622 to move downward. At the same time, the upper limit block 622 drives the limit rod 621 to move downward on the lower limit block 623. This causes the limit rod 621 to pull the sliding frame 625 to move inside the plate 61 through the connecting rod 624. This causes the sliding frame 625 to pull the third spring 628 to move to one side of the limit rod 621. This causes the sliding frame 625 to pull the contact mechanism 626 to move to both sides of the plate 61. This avoids interference from the contact mechanism 626 when performing compressive strength testing on the bricks.

[0048] Please see Figures 10-11The contact mechanism 626 includes a contact frame 6261, the bottom of which is slidably connected to the top of the placement plate 61. Large triangular plates 6262 are fixedly connected to both sides of the contact frame 6261. The bottoms of the large triangular plates 6262, small triangular plates 6264, and scraper 6266 are all in contact with the top of the placement plate 61. A small triangular plate 6264 is fixedly connected to the contact frame 6261 near the middle of the two large triangular plates 6262. A round rod 6263 is slidably connected to one side of the contact frame 6261. A baffle plate 6265 is fixedly connected to the end of the round rod 6263 away from the contact frame 6261. A second spring 6267 is sleeved on the round rod 6263. One end of the second spring 6267 is fixedly connected to the inner side of the baffle plate 6265, and the other end of the second spring 6267 is fixedly connected to the inner side of the contact frame 6261. A scraper 6266 is fixedly connected to the side of the contact frame 6261 away from the baffle plate 6265. When the sliding frame 625 passes through… The third spring 628 is pulled back to reset, and the inner side of the placement plate 61 is moved back to reset. This causes the sliding frame 625 to drive the contact frame 6261 to move on the top of the placement plate 61. At the same time, two large triangular plates 6262 and one small triangular plate 6264 are set on the side of the contact frame 6261 near the abutment plate 6265. When the contact frame 6261 moves on the top of the placement plate 61, the large triangular plates 6262 and the small triangular plates 6264 can contact and clean the top of the placement plate 61. The triangular plates have certain angles and edges, which can achieve better depth cleaning effect compared with flat cleaning tools, ensuring the cleanliness of the placement plate 61 and removing debris from the placement plate 61. This can prevent these debris from affecting the flatness of the contact between the brick and the placement plate 61, ensuring that the brick is placed stably on the placement plate 61. Therefore, during the compressive strength test, the brick can be evenly stressed, improving the accuracy of the test results.

[0049] Please see Figure 12The collection mechanism 63 includes a suction mechanism 631 and a first filter plate 632. The bottom of the suction mechanism 631 is fixedly connected to the bottom of the inner cavity of the main body 1, and a second filter plate 633 is fixedly connected to the top of the suction mechanism 631. The side of the second filter plate 633 is fixedly connected to the inner side of the main body 1. The first filter plate 632 is disposed above the second filter plate 633, and the side of the first filter plate 632 is fixedly connected to the inner side of the main body 1. The top of the first filter plate 632 is fixedly connected to the bottom of the placement rack 627. When the contact mechanism 626 cleans the top of the placement plate 61... The suction mechanism 631 can be activated. After the suction mechanism 631 is activated, it will perform suction work, adsorbing the debris and dust that fall during the cleaning process through the first filter plate 632 and causing them to fall onto the second filter plate 633 for collection and storage. This prevents them from falling again or adhering to the placement plate 61, further improving the cleanliness of the placement plate 61 and achieving a more thorough cleaning effect. It also avoids the possibility that residual debris and dust on the placement plate 61 may cause uneven brick placement, resulting in uneven stress on the bricks during compressive strength testing and affecting the accuracy of the test results.

[0050] Specific workflow:

[0051] Based on the expected strength grade of the finished concrete brickwork and relevant standard requirements, set the test loading speed, maximum loading force and other parameters in the control component 2 of the pressure testing machine;

[0052] Place the prepared concrete brickwork specimen on the fixed part 6 of the main body 1, aligning the center of the specimen with the center of the moving part 5.

[0053] Start the transmission component 4, which drives the moving component 5 to gradually approach the specimen and begin applying pressure. Apply the load to the specimen slowly and evenly according to the preset loading speed. During the loading process, closely observe the specimen and the equipment to ensure that the pressure testing machine runs smoothly and that the data acquisition system records the load and deformation data normally.

[0054] The data acquisition system of the compression testing machine records the load and deformation data of the specimen in real time during the compression process. This data includes the load value at each moment and the vertical deformation of the specimen.

[0055] When the specimen reaches the failure limit and completely loses its load-bearing capacity, and the load value of the pressure testing machine no longer increases or even begins to decrease, stop loading, turn off the power to the pressure testing machine, and ensure that the equipment is in a safe state.

[0056] Test data is exported from the data acquisition system of the compression testing machine, and the data is processed and analyzed in accordance with the requirements of relevant standards and specifications. The compressive strength of the specimen is calculated, which is generally obtained by dividing the failure load by the compression area of ​​the specimen. At the same time, the mechanical properties of the finished concrete brickwork are comprehensively evaluated based on the recorded failure mode and deformation data.

[0057] After the concrete finished brick masonry compressive strength test is completed, the transmission component 4 drives the moving component 5 to move upward to reset, and the cleaning component 7 can clean the bottom of the moving component 5 at the same time.

[0058] When the concrete brickwork is being tested for strength, the output end of the transmission component 4 drives the fixed housing 51 to move downward, so that the fixed housing 51 drives the connecting frame 54 to move downward through the connecting frame 52, so that the pressure plate mechanism 53 abuts against the top of the concrete brickwork placed on the fixed component 6.

[0059] By providing multiple pressure plate mechanisms 53 in the inner cavity of the fixed outer shell 51, the pressure plate mechanism 53 is divided into multiple small blocks, and the height of each small block can be adjusted independently. By adjusting the height of these small blocks, the pressure plate mechanism 53 can better fit the surface of the brickwork and achieve full contact compression.

[0060] Pressure sensors 536 are distributed at the bottom of the movable frame 535 to monitor the pressure distribution between the pressure block 534 and the brick in real time, providing data support for subsequent pressure adjustment, ensuring that the pressure block 534 contacts the brick in the appropriate position and applies pressure, ensuring that the pressure is evenly distributed on the brick surface, and avoiding inaccurate detection results due to position deviation. The pressure sensor 536 can measure the pressure between the pressure block 534 and the brick in real time.

[0061] During the detection process, the pressure sensor 536 can accurately capture pressure changes and convert the pressure signal into a processable signal form such as an electrical signal. It sends a command to the drive component 532. When the drive component 532 receives the command from the pressure sensor 536, the output end of the drive component 532 drives the pressure block 534 to move downward through the moving rod 533, so that the pressure block 534 can better fit the surface of the brick and achieve full contact compression.

[0062] Therefore, unlike ordinary pressure plates, there is no need for frequent manual adjustment of the pressure plate position or the addition of auxiliary tools such as shims to adapt to different brick shapes and sizes. The adaptation process can be completed quickly and automatically, saving test preparation time and improving overall test efficiency.

[0063] By providing a connecting component 537 on the side of the pressure block 534, when the connecting frame 52 drives the pressure sensor 536 to press against the surface of the brick, when the pressure is applied, the pressure on the moving frame 535 is greater than the tensile force of the first spring 5373, so the moving frame 535 slides on the connecting sleeve 5371 through the sliding sleeve 5372, thereby allowing the moving frame 535 to slide inside the pressure block 534, thus avoiding pressure damage to the pressure sensor 536 and the bottom of the moving frame 535, and at the same time providing a certain degree of protection for the brick, preventing premature cracking or damage to the brick due to excessive or uneven pressure. The protective effect is more obvious for some bricks with low strength or high brittleness.

[0064] When testing the compressive strength of the brickwork, the brickwork is placed stably on the placement plate 61, and the two sides of the brickwork are clamped and limited by the limiting mechanism 62 on both sides, thereby ensuring that the center of the brickwork is aligned with the center of the moving part 5. When the output end of the transmission part 4 drives the moving part 5 to perform the compression test on the brickwork on the placement plate 61, the broken concrete brickwork fragments can be collected by opening the collection mechanism 63.

[0065] When the output end of the transmission component 4 drives the fixed housing 51 to move towards the bricks on the placement plate 61, the fixed housing 51 simultaneously drives the upper limit block 622 to move downward. At the same time, the upper limit block 622 drives the limit rod 621 to move downward on the lower limit block 623. This causes the limit rod 621 to pull the sliding frame 625 to move inside the placement plate 61 via the connecting rod 624. This causes the sliding frame 625 to pull the third spring 628 to move to one side of the limit rod 621. This causes the sliding frame 625 to pull the contact mechanism 626 to move to both sides of the placement plate 61, thereby preventing the contact mechanism 626 from interfering with the compressive strength testing of the bricks.

[0066] After the compressive strength test of the brickwork is completed, the output end of the transmission component 4 drives the fixed housing 51 to move upward to reset. This causes the fixed housing 51 to move downward on the lower limit block 623 via the upper limit block 622, which in turn causes the sliding frame 625 to move downward on the inner side of the placement plate 61 by the reset pull of the third spring 628. This causes the sliding frame 625 to drive the contact mechanism 626 to make contact movement at the top of the placement plate 61 after the compressive strength test.

[0067] When the sliding frame 625 is pulled back by the third spring 628, it moves to the inside of the placement plate 61, thereby causing the sliding frame 625 to drive the contact frame 6261 to move on the top of the placement plate 61. At the same time, two large triangular plates 6262 and one small triangular plate 6264 are provided on the side of the contact frame 6261 near the abutment plate 6265. When the contact frame 6261 moves on the top of the placement plate 61, the large triangular plates 6262 and the small triangular plates 6264 can contact and clean the top of the placement plate 61. The triangular plates have certain angles and edges, which can achieve a better depth cleaning effect compared with flat cleaning tools, ensuring the cleanliness of the placement plate 61 and removing debris from the placement plate 61. This can prevent these debris from affecting the flatness of the contact between the brick and the placement plate 61, ensuring that the brick is placed stably on the placement plate 61. Therefore, during the compressive strength test, the brick can be evenly stressed, improving the accuracy of the test results.

[0068] When testing the compressive strength of the brickwork, the brickwork is placed stably on the placement plate 61, and the abutment plate 6265 abuts against the two sides of the brickwork. The abutment plate 6265 is supported by the tension of the second spring 6267, so that the round rod 6263 drives the abutment plate 6265 to abut against the two sides of the brickwork, thereby ensuring that the center of the brickwork is aligned with the center of the moving part 5.

[0069] When the contact mechanism 626 cleans the top of the placement plate 61, the suction mechanism 631 can be activated. After the suction mechanism 631 is activated, it will perform suction to absorb the debris and dust that fall during the cleaning process through the first filter plate 632 and collect and store them on the second filter plate 633. This prevents them from falling or adhering to the placement plate 61 again, further improving the cleanliness of the placement plate 61 and achieving a more thorough cleaning effect. It also prevents the debris and dust remaining on the placement plate 61 from causing uneven brick placement, resulting in uneven stress on the bricks during the compressive strength test and affecting the accuracy of the test results.

[0070] After the compressive strength test of the brickwork is completed, the fixed housing 51 is moved upward by the output end of the transmission component 4. Then, the drive mechanism 75 is activated. The telescopic rod 76 of the drive mechanism 75 drives the cleaning roller 78 through the connecting block 77 to move to the bottom of the fixed housing 51. This allows the cleaning roller 78 to clean the bottom of the pressure block 534, the moving frame 535, and the pressure sensor 536. This avoids the phenomenon that a large amount of residual debris and dust will adhere to the bottom of the pressure block 534, the moving frame 535, and the pressure sensor 536 after the compressive strength test of the brickwork, which would interfere with subsequent testing.

[0071] After the cleaning roller 78 finishes cleaning, the output end of the drive mechanism 75 moves into the inner cavity of the cleaning housing 71 via the telescopic rod 76 and connecting block 77. Simultaneously, a rotating rod 73 and a cleaning rod 74 are provided inside the cleaning housing 71, causing the cleaning roller 78 to rotate against the side of the cleaning rod 74 when it enters the cleaning housing 71. This allows the cleaning rod 74 to clean the side of the cleaning roller 78, preventing excessive impurities on the cleaning roller 78 from interfering with subsequent cleaning. Furthermore, any impurities removed by the cleaning rod 74 from the surface of the cleaning roller 78 can be collected inside the cleaning housing 71 via the mesh plate 72.
