Abstract
Description
Technical Field
[0001] This utility model relates to the field of headstock technology, and in particular to a headstock machine for the production of calcium silicate boards. Background Technology
[0002] Calcium silicate board, as a new type of green and environmentally friendly building material, not only has the functions of traditional gypsum board, but also has the advantages of superior fire resistance, moisture resistance, and ultra-long service life. It is widely used in ceilings and partitions of industrial and commercial buildings, as well as in home decoration, furniture lining, billboard lining, warehouse shelving, raised floor, and wall panels for indoor projects such as tunnels. In the production process of calcium silicate board, a grouting machine is used to inject grout and then flatten the grout.
[0003] In the existing technology, traditional equipment has certain shortcomings in flattening slurry. Because the slurry contains colloidal components such as silica sol and cellulose ether, it has a certain viscosity. When the flattening roller flattens the slurry, the slurry adheres to the surface of the flattening roller. After the heat of the slurry is lost, it will solidify on the surface of the flattening roller, resulting in insufficient flatness of the flattening roller surface and inability to flatten continuously. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a headstock machine for the production of calcium silicate boards, which has the advantages of increasing slurry fluidity, elastic scraping, and brush cleaning, thus solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a flow mill for calcium silicate board production, comprising a base plate, a motor A fixedly mounted on the top of the base plate, support plates symmetrically fixedly mounted on both sides of the base plate, a drive roller rotatably mounted between the support plates adjacent to the motor A, a belt A drivingly connecting the output end of the motor A and the end of the drive roller, a driven roller rotatably mounted between the support plates adjacent to the drive roller, a conveyor belt drivingly connecting the outer rings of the drive roller and the driven roller, a cross plate fixedly connected between the support plates on the same side, an oil tank fixedly mounted on the surface of the base plate on the side of the motor A, a heating assembly provided inside the oil tank, a motor B fixedly mounted on the top of the oil tank, a gear pump fixedly mounted on the top of the base plate between the motor A and the oil tank, a scraping device fixedly mounted above the support plate on the side of the oil tank, and a brushing device fixedly mounted on the top of the scraping device.
[0006] Through the above structural design, and by setting up the cooperation between the flattening roller, the oil tank and the gear pump, the slurry in contact with the flattening roller maintains good fluidity and reduces viscosity. The slurry adhering to the surface of the flattening roller is removed by setting up scraping and brushing devices.
[0007] Preferably, the horizontal plate includes a vertical plate, and the vertical plate is provided in the middle of the horizontal plate near the oil tank. A flattening roller is rotatably installed inside the vertical plate above the conveyor belt. A belt B is connected between the end of the flattening roller and the output end of the motor B. A heat-conducting oil channel is opened inside the flattening roller.
[0008] With the above structural design, the heat transfer oil transfers heat to the surface of the flattening roller through the inner wall of the heat transfer oil channel, so that the surface of the flattening roller comes into flat contact with the slurry, thereby reducing the adhesion between the slurry and the surface of the flattening roller.
[0009] Preferably, an input pipe is fixedly connected between the input port of the gear pump and the oil tank, an output pipe is connected between the output port of the gear pump and one side of the flattening roller, the output pipe is rotatably connected to the flattening roller, and the output pipe and the flattening roller are mechanically sealed to each other, and a return pipe is connected between the other side of the flattening roller and the oil tank, the return pipe and the flattening roller are rotatably connected and mechanically sealed to each other.
[0010] With the above-mentioned structure, the heat transfer oil inside the oil tank is drawn out through the input pipe and then pumped into the heat transfer oil channel through the output pipe. The heat transfer oil flows inside the heat transfer oil channel to transfer heat to the surface of the flattening roller.
[0011] Preferably, the scraping device includes support legs, which are fixedly connected to the top of the support plate. An inner arc block is fixedly connected between the tops of the support legs. The inner surface of the inner arc block is arc-shaped. An elastic scraper is rotatably sleeved at the end of the inner arc block. One end of the elastic scraper is in contact with the outer ring of the flattening roller. A spring assembly is fixedly connected between the elastic scraper and the top of the inner arc block.
[0012] With the above structural design, the end of the elastic scraper is always in close contact with the surface of the flattening roller, scraping off the slurry adhering to the surface of the flattening roller. The scraped slurry falls from the outer wall of the elastic scraper and the inner arc surface of the inner arc block into the slurry to be flattened, thus avoiding slurry waste.
[0013] Preferably, the brushing device includes a fixed frame and a brush roller. The fixed frame is fixedly installed on the top of the scraping device. The brush roller is rotatably installed inside the fixed frame. The surface of the brush roller is uniformly provided with nylon bristles. A collection groove is opened inside the fixed frame below the brush roller. A transmission column is rotatably installed on one side of the fixed frame. The transmission column and the brush roller are located inside the fixed frame and are driven by gear meshing. A belt C is connected between the end of the transmission column and the end of the flattening roller.
[0014] With the above-mentioned structure, the brush roller rotates in a different direction from the flattening roller. The nylon bristles on its surface brush away any remaining residue in the gaps of the flattening roller, while sweeping any residual slurry from the edge of the flattening roller into the collection tank.
[0015] This utility model has the following advantages:
[0016] 1. This flow mill for calcium silicate board production continuously scrapes away slurry by incorporating an oil tank, heat transfer oil channels, a gear pump, a scraping device, and an elastic scraper. The gear pump pumps heat transfer oil from the oil tank into the heat transfer oil channels through input and output pipes. The heat transfer oil then transfers heat to the surface of the flattening roller through the inner wall of the heat transfer oil channels. Even after flattening, some slurry still adheres to the surface of the flattening roller. At this point, the side of the flattening roller with the adhered surface rotates to the scraping device. Due to the continuous contraction of the elastic spring assembly, one end of the elastic scraper remains in close contact with the surface of the flattening roller. The slurry remaining on the surface of the flattening roller is scraped away by the elastic scraper. The scraped slurry falls along the inner wall of the elastic scraper and the inner arc surface of the inner arc block into the flattened slurry, avoiding slurry waste and achieving the effect of reducing viscosity and uniform scraping.
[0017] 2. This flow mill for calcium silicate board production, through the setting of a brush removal device, brush roller, collection tank, etc., rotates the surface of the flattening roller, which has been scraped by the elastic scraper, to the brush removal device. When the flattening roller rotates, it drives the transmission column to rotate via belt C. The transmission column drives the brush roller to rotate in the opposite direction through gear transmission. Due to the different rotation directions of the brush roller and the flattening roller, the nylon bristles on the surface of the brush roller brush away the residue in the gaps not cleaned by the elastic scraper on the surface of the flattening roller. At the same time, it sweeps off any residual slurry at the edge of the elastic scraper, so that the brushed-off slurry is thrown into the collection tank for storage, avoiding contamination of the slurry to be flattened, and achieving the effect of uniformly brushing off the slurry.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-2 A flow mill for producing calcium silicate boards includes a base plate 1, a motor A2 fixedly mounted on the top of the base plate 1, support plates 11 symmetrically fixedly mounted on both sides of the base plate 1, a drive roller 12 rotatably mounted between the support plates 11 adjacent to the motor A2, a belt A21 drivingly connecting the output end of the motor A2 and the end of the drive roller 12, a driven roller rotatably mounted between the support plates 11 adjacent to the drive roller 12, a conveyor belt 13 drivingly connecting the outer ring of the drive roller 12 and the driven roller, a cross plate 3 fixedly connected between the support plates 11 on the same side, an oil tank 4 fixedly mounted on the surface of the base plate 1 on the side of the motor A2, the oil tank 4 containing heat transfer oil and a heating component, a motor B5 fixedly mounted on the top of the oil tank 4, a gear pump 6 fixedly mounted on the top of the base plate 1 between the motor A2 and the oil tank 4, a scraping device 7 fixedly mounted above the support plate 11 on the side of the oil tank 4, and a brushing device 8 fixedly mounted on the top of the scraping device 7.
[0026] In practical applications, this device achieves good fluidity and reduces viscosity of the slurry in contact with the flattening roller 32 by coordinating the flattening roller 32, oil tank 4, and gear pump 6. When the flattening roller 32 is working, the gear pump 6 draws heated heat transfer oil from inside the oil tank 4 through the input pipe 61, and then pumps it into the heat transfer oil channel 33 through the output pipe 62. The heat transfer oil transfers heat to the surface of the flattening roller 32 through the inner wall of the heat transfer oil channel 33, reducing the viscosity between the slurry and the surface of the flattening roller 32 during the flattening process. Temperature control maintains good fluidity of the slurry and prevents it from solidifying on the surface of the flattening roller 32 due to heat loss. Subsequently, the heat transfer oil inside the heat transfer oil channel 33 flows back to the inside of the oil tank 4 through the return pipe 63, and is replenished again after heating. Through the linkage of the above structures, the temperature of the surface of the flattening roller 32 in contact with the slurry is maintained, and the viscosity between the flattening roller 32 and the slurry is reduced.
[0027] The slurry adhering to the surface of the flattening roller 32 is removed by setting up a scraping device 7 and a brushing device 8. When the scraping device 7 is working, the elastic scraper 73 is continuously contracted by the spring assembly 74, so that the end of the elastic scraper 73 is always in contact with the surface of the flattening roller 32. After the flattening roller 32 is flattened by the slurry, the excess slurry on the surface is scraped off by the elastic scraper 73. When the brushing device 8 is working, the brush roller 82 contacts the flattening roller 32, so that the brush roller 82 brushes away the gaps that the elastic scraper 73 did not clean, and sweeps off any slurry that may remain on the edge of the scraper. Thus, the slurry remaining on the surface of the flattening roller 32 is brushed off, so that the surface of the flattening roller 32 is clean when it is flattened by the slurry.
[0028] Please see Figures 1-4 The horizontal plate 3 includes a vertical plate 31. The vertical plate 31 is located in the middle of the horizontal plate 3 near the oil tank 4. A flattening roller 32 is rotatably installed inside the vertical plate 31 above the conveyor belt 13. A belt B51 is connected between the end of the flattening roller 32 and the output end of the motor B5. A heat-conducting oil channel 33 is opened inside the flattening roller 32.
[0029] When the flattening roller 32 is working, the output end of the motor B5 drives the flattening roller 32 through the belt B51, and the gear pump 6 pumps the heat-conducting oil with heat in the oil tank 4 into the heat-conducting oil passage 33 through the input pipe 61 and the output pipe 62. The heat-conducting oil transfers heat to the surface of the flattening roller 32 through the inner wall of the heat-conducting oil passage 33, so that the surface of the flattening roller 32 comes into flat contact with the slurry, reducing the adhesion between the slurry and the surface of the flattening roller 32.
[0030] Please see Figures 1-3An input pipe 61 is fixedly connected between the input port of the gear pump 6 and the oil tank 4. An output pipe 62 is connected to one side of the flattening roller 32. The output pipe 62 is rotatably connected to the flattening roller 32 and the output pipe 62 and the flattening roller 32 are mechanically sealed to each other. A return pipe 63 is connected between the other side of the flattening roller 32 and the oil tank 4. The return pipe 63 and the flattening roller 32 are rotatably connected and mechanically sealed to each other.
[0031] When the gear pump 6 is in actual operation, it draws the heat transfer oil from the oil tank 4 through the input pipe 61 and then pumps it into the heat transfer oil channel 33 through the output pipe 62. The heat transfer oil flows inside the heat transfer oil channel 33 to transfer heat to the surface of the flattening roller 32. When the heat transfer oil reaches the other end of the heat transfer oil channel 33, it flows back to the inside of the oil tank 4 through the return pipe 63, thus achieving the effect of heat transfer oil circulation.
[0032] Please see Figures 1-4 The scraping device 7 includes a support leg 71, which is fixedly connected to the top of the support plate 11. An inner arc block 72 is fixedly connected between the tops of the support legs 71. The inner surface of the inner arc block 72 is arc-shaped. An elastic scraper 73 is rotatably sleeved at the end of the inner arc block 72. One end of the elastic scraper 73 is in contact with the outer ring of the flattening roller 32. A spring assembly 74 is fixedly connected between the elastic scraper 73 and the top of the inner arc block 72.
[0033] When the scraping device 7 is working, the spring assembly 74 continuously contracts, causing the elastic scraper 73 to rotate inside the inner arc block 72. The end of the elastic scraper 73 is always in close contact with the surface of the flattening roller 32, scraping off the slurry adhering to the surface of the flattening roller 32. The scraped slurry falls from the outer wall of the elastic scraper 73 and the inner arc surface of the inner arc block 72 into the slurry to be flattened, avoiding slurry waste. The slurry scraped off by the elastic scraper 73 is all fluid slurry and will not affect the flattening effect.
[0034] Please see Figures 1-5 The brushing device 8 includes a fixed frame 81 and a brush roller 82. The fixed frame 81 is fixedly installed on the top of the scraping device 7. The brush roller 82 is rotatably installed inside the fixed frame 81. The surface of the brush roller 82 is uniformly covered with nylon bristles. The contact depth between the nylon bristles and the flattening roller 32 is 3mm-5mm. A collection groove 83 is provided inside the fixed frame 81 below the brush roller 82. A transmission column 84 is rotatably installed on one side of the fixed frame 81. The transmission column 84 and the brush roller 82 are located inside the fixed frame 81 and are driven by gear meshing. A belt C85 is connected between the end of the transmission column 84 and the end of the flattening roller 32.
[0035] When the flattening roller 32 rotates, it is driven by the belt C85 connected between its end and the transmission column 84, which drives the brush roller 82 to rotate in the opposite direction. After the flattening roller 32 flattens the slurry, the slurry remaining on its surface will be initially scraped off by the elastic scraper 73. Then it rotates to the brush removal device 8, where the brush roller 82 rotates in the opposite direction to the flattening roller 32. The nylon bristles on its surface brush off the slurry residue in the gaps of the flattening roller 32 that has not been completely cleaned. The gap residue comes from the slurry in the tiny pits generated by the long-term use of the flattening roller 32. At the same time, it sweeps the slurry that may remain on the edge of the flattening roller 32 into the collection tank 83, avoiding it from falling on the elastic scraper 73 or inside the flattened slurry.
[0036] Working principle: A calcium silicate board coated or filled with slurry is placed on the surface of conveyor belt 13. Motor A2 is started, and its output drives the drive roller 12 and conveyor belt 13 to rotate via belt A21, causing the calcium board to be conveyed towards the flattening roller 32 on the surface of conveyor belt 13. Simultaneously, motor B5 and gear pump 6 are started. Motor B5's output drives the flattening roller 32 to rotate via belt B51. Gear pump 6 pumps the heat transfer oil from inside oil tank 4 into the heat transfer oil channel through input pipe 61 and output pipe 62. Inside the heat transfer oil channel 33, the heat transfer oil is used to transfer heat to the surface of the flattening roller 32 through the inner wall of the heat transfer oil channel 33. After the flattening roller 32 contacts and flattens the slurry on the surface of the calcium board, the surface of the flattening roller 32 has a temperature that is almost the same as that of the slurry. When the flattening roller 32 flattens the slurry, the slurry in contact with its surface maintains good fluidity, reducing the viscosity between the slurry and the flattening roller 32. Then, the heat transfer oil inside the heat transfer oil channel 33 flows back to the inside of the oil tank 4 through the return pipe 63, so as to achieve the effect of circulating and heating the flattening roller 32.
[0037] When the flattening roller 32 is flattened at a constant temperature, a certain amount of slurry will still adhere to its surface. At this time, the side of the flattening roller 32 with the adhered surface rotates to the scraping device 7. Due to the continuous contraction of the elastic spring assembly 74, the elastic scraper 73 keeps one end in close contact with the surface of the flattening roller 32. The slurry remaining on the surface of the flattening roller 32 is scraped off by the elastic scraper 73. The scraped slurry falls into the flattened slurry along the inner wall of the elastic scraper 73 and the inner arc surface of the inner arc block 72, thus avoiding slurry waste.
[0038] After being scraped by the elastic scraper 73, the surface of the flattening roller 32 rotates to the brushing device 8. When the flattening roller 32 rotates, it drives the transmission column 84 to rotate via the belt C85. The transmission column 84 drives the brush roller 82 to rotate in the opposite direction via gear transmission. Due to the different directions of rotation of the brush roller 82 and the flattening roller 32, the nylon bristles on the surface of the brush roller 82 brush away the gaps and residues that the elastic scraper 73 did not clean on the surface of the flattening roller 32. At the same time, it sweeps off any residual slurry that may remain on the edge of the elastic scraper 73, so that the brushed-off slurry is thrown into the collection tank 83 for storage, so as to avoid contaminating the slurry to be flattened.
