[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0034] See also Figures 1 to 4 ,in Figure 1 and Figure 5The "50" in the figure represents a cement board. The utility model provides a manufacturing device for a fiber cement board, comprising a working frame 10, a plastering mechanism 20 and a laying mechanism 30. Rollers 11 are rotatably provided at both ends of the top of the working frame 10. The two rollers 11 are rotatably connected by a conveyor belt 12. A plurality of support shafts 13 equidistantly distributed are rotatably connected at the top of the working frame 10 and located between the two rollers 11. There are two plastering mechanisms 20, which are arranged on the working frame 10 at intervals. The laying mechanism 30 is arranged on the working frame 10, and the laying mechanism 30 is located between the two plastering mechanisms 20, and is used to lay a fiber mesh cloth 34 on the surface of the cement board.
[0035] When in use, the cement boards that are adjacent to each other are conveyed on the conveyor belt 12. The first plastering mechanism 20 first applies a layer of cement on the surface of the cement board, thereby wetting the surface of the cement board and making the surface of the cement board sticky. Then, a layer of fiber mesh cloth 34 is laid on the first layer of cement on the cement board through the laying mechanism 30, so that the fiber mesh cloth 34 is attached to the first layer of cement on the surface of the cement board. After continued conveyance by the conveyor belt 12, the second plastering mechanism 20 further applies another layer of cement liquid on the fiber mesh cloth 34, so that the second layer of cement is applied on the fiber mesh cloth 34 and the first layer of cement, and the fiber mesh cloth 34 is fixed to finally form a fiber cement board. The entire application of cement liquid and the fiber mesh cloth 34 are automatically completed, so that the application thickness of cement can be controlled, and because the cement boards are adjacent to each other, the application of cement and the laying of fiber mesh cloth 34 are carried out continuously, which improves work efficiency.
[0036] See also Figure 5 , Figure 6 and Figure 7 The plastering mechanism 20 includes a storage tank 21, a plastering frame 22 and two adjusting parts 23. The two adjusting parts 23 form a group. The two groups of adjusting parts 23 are arranged on the work frame 10 at intervals. Each plastering frame 22 is suspended above the conveyor belt 12 through a group of adjusting parts 23. The two storage tanks 21 are arranged above the plastering frame 22 through a bracket 25. Among them, the front and rear sides of the plastering frame 22 are at a certain distance from the cement board, and the left and right sides of the plastering frame 22 are fitted and slid on the cement board, so that the cement liquid can be laid on the surface of the cement board. A layer of cement is also avoided from flowing out from the left and right sides of the plastering frame 22. The first plastering frame 22 is used to hold the first layer of cement liquid, and the second plastering frame 22 is used to hold the second layer of cement liquid, so that two layers of cement are laid on the surface of the cement board, and the fiber mesh cloth 34 is fixed on the surface of the cement board.
[0037] Specifically, the adjusting member 23 includes a first support frame 231, a cross bar 232 and a vertical bar 233. The two first support frames 231 in each group of adjusting members 23 are symmetrically arranged on both sides of the top of the working frame 10. Two spaced vertical bars 233 are provided on both sides of the plastering frame 22. A cross bar 232 is fixedly connected between the tops of the two vertical bars 233 on the same side. A driving member 24 is provided on the top of each first support frame 231, and the driving member 24 can drive the corresponding cross bar 232 to move up and down.
[0038] When the cement board is conveyed by the conveyor belt 12 into the bottom of the first plastering frame 22, cement liquid flows out from the bottom of the storage tank 21 into the first plastering frame 22. At this time, the cement liquid in the first plastering frame 22 covers the cement board, so that the cement liquid is laid on the surface of the cement board. As the conveyor belt 12 conveys the cement board, the front side of the cement board moves to the outside of the front side of the first plastering frame 22. Since the front and rear sides of the first plastering frame 22 have a certain gap from the cement board (the gap is the thickness of the first layer of cement on the surface of the cement board), a certain thickness of cement liquid solidifies on the surface of the cement board to form a first cement layer, and the excess cement liquid in the first plastering frame 22 is blocked by the front side of the plastering frame 22 and remains in the plastering frame 22 to apply a cement layer to the surface of the next cement board; the principle of the second plastering frame 22 is the same as that of the above-mentioned first plastering frame 22, and the second cement layer is applied on the first cement layer, so that the fiber mesh cloth 34 is fixed on the first cement layer.
[0039] The driving member 24 includes a box body 241, a worm 242, a worm wheel 243, a rotating sleeve 244 and a lifting screw 245. The box body 241 is fixedly provided on the top of each first support frame 231. The worm 242 is rotatably provided on one side of the box body 241. A supporting block 246 is fixedly provided on the other side of the box body 241. A first receiving groove 247 is provided on one side of the supporting block 246 close to the worm 242. A vertical rotating sleeve 244 is rotatably provided in the first receiving groove 247. The worm wheel 243 is fixedly sleeved on the outside of the rotating sleeve 244, and one side of the worm wheel 243 extends to the outside of the first receiving groove 247 and meshes with the worm wheel 243. The inner thread sleeve of the rotating sleeve 244 is provided with a lifting screw 245. The bottom of the lifting screw 245 rotates through the support block 246 and the bottom of the box body 241 and is rotated to the middle of the cross bar 232. The top of the lifting screw 245 rotates through the support block 246 and the top of the box body 241 and extends to the outside. Among them, the inner wall of the rotating sleeve 244 is provided with a limited sliding groove, and the outer wall of the lifting screw 245 is fixedly provided with a limited sliding block. The end of the limited sliding block is inserted into the limited sliding groove and slidably connected, so that the lifting screw 245 is limited to slide in the rotating sleeve 244 and can only move up and down.
[0040] Before use, the worm gear 242 is rotated to drive the worm wheel 243 to rotate, and the worm wheel 243 drives the rotating sleeve 244 to rotate. Due to the threaded connection between the rotating sleeve 244 and the lifting screw 245, the rotating sleeve 244 drives the lifting screw 245 to move up and down, and then the lifting screw 245 drives the two vertical rods 233 to rise and fall, so as to adjust the distance between the plastering frame 22 and the cement board, and then adjust the coating thickness of the first layer of cement. Moreover, the height of the second plastering frame 22 is slightly higher than the first plastering frame 22, so as to facilitate the coating of the second layer of cement on the cement board.
[0041] Preferably, one end of the worm 242 rotates through the side wall of the box body 241 and extends to the outside and is fixed with a knob 40, so that the worm 242 can be rotated more conveniently through the knob 40.
[0042] Furthermore, the front side of the plastering frame 22 along the conveying direction of the conveyor belt 12 is inclined so that the top opening area of the plastering frame 22 is smaller than the bottom opening area. The inclined front side of the plastering frame 22 is convenient for blocking the excess cement liquid inside the plastering frame 22, and the inclination of the front side of the plastering frame 22 makes it easier to apply and smooth the surface of the cement board.
[0043] like Figure 1 As shown, in this embodiment, the laying mechanism 30 includes a second supporting frame 31, a rotating shaft 32 and an auxiliary shaft 33. The second supporting frames 31 are fixedly provided on both sides of the top of the work frame 10, and the second supporting frames 31 are located between the two first supporting frames 231. A rotating shaft 32 is rotatably provided between the tops of the two second supporting frames 31, and a fiber mesh cloth 34 is wound around the outside of the rotating shaft 32. An auxiliary shaft 33 is fixedly provided between the bottoms of one side of the two second supporting frames 31, and the end of the fiber mesh cloth 34 is passed around the auxiliary shaft 33 before being laid on the surface of the cement board. Among them, the rotating shaft 32 and the auxiliary shaft 33 are not in the same vertical plane, and the auxiliary shaft 33 is close to the first plastering mechanism 20 relative to the rotating shaft 32, and the auxiliary shaft 33 is close to the surface of the cement board.
[0044] After the first layer of cement is applied to the cement board, the surface of the cement board is moistened, and then the end of the fiber mesh cloth 34 is laid on the first layer of cement. At this time, the fiber mesh cloth 34 will be attached to the surface on the front side of the first layer of cement. Since the auxiliary shaft 33 is close to the surface of the cement board, as the conveyor belt 12 conveys the cement forward, the fiber mesh cloth 34 is driven to move forward and stick to the first layer of cement. At this time, the fiber mesh cloth 34 continuously extends and unfolds from the rotating shaft 32, thereby realizing the continuous laying of the fiber mesh cloth 34 on the surfaces of multiple cement boards that are closely together.
[0045] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, a discharge pipe 211 is fixedly provided at the bottom of the storage tank 21, and a discharge valve 212 is provided on the discharge pipe 211. The discharge valve 212 is a prior art, and its opening and closing is controlled by a corresponding program. Through the control of the discharge valve 212, the cement liquid in the storage tank 21 will intermittently flow out of the discharge pipe 211 into the corresponding plastering frame 22, so as to avoid too much cement liquid remaining in the plastering frame 22.
[0046] A stirring motor 261 is fixedly provided on the top of the bracket 25, and the output shaft of the stirring motor 261 is vertically downward and fixedly provided with a stirring shaft 262. The bottom of the stirring shaft 262 passes through the top of the bracket 25 and extends into the storage tank 21, and a plurality of stirring blades 263 are fixedly provided on the outer side of the bottom of the stirring shaft 262. The stirring motor 261 is started to drive the stirring shaft 262 to rotate, thereby driving the stirring blades 263 to stir the cement liquid in the storage tank 21, so that the cement liquid in the storage tank 21 is more uniform.
[0047] like Figure 3 As shown, in this embodiment, a driving motor 14 is provided at the bottom of the output end of the work frame 10 through a support platform, one end of the roller 11 rotates through the top side wall of the work frame 10 and extends to the outside and is fixed with a sprocket 15, and the output shaft of the driving motor 14 is also fixed with a sprocket 15, and the two sprockets 15 are rotatably connected by a chain 16. By starting the driving motor 14, the roller 11 is driven to rotate through the transmission of the sprocket 15 and the chain 16, thereby driving the conveyor belt 12 to rotate and thus conveying the cement board on the work frame 10.
[0048] The working principle of the utility model is as follows: before use, the worm 242 is first rotated to drive the worm wheel 243 to rotate, and the height of the plastering frame 22 from the cement board is adjusted; then, multiple cement boards are conveyed by the conveyor belt 12, and when the first cement board moves to the bottom of the first plastering frame 22, the bottom of the storage tank 21 flows out into the first plastering frame 22, and at this time, the cement liquid in the first plastering frame 22 covers the cement board, so that the cement liquid is laid on the surface of the cement board, and as the conveyor belt 12 conveys the cement board, the front side of the cement board moves to the outside of the front side of the first plastering frame 22, so that a certain thickness of cement liquid solidifies on the surface of the cement board to form a first cement layer; then the end of the fiber mesh cloth 34 is laid on the first layer of cement, and as the conveyor belt 12 The forward transmission of cement drives the fiber mesh cloth 34 to move forward and stick to the first layer of cement. At this time, the fiber mesh cloth 34 continues to extend and unfold from the rotating shaft 32; when the cement board moves to the bottom of the second plastering frame 22, cement liquid flows out of the bottom of the second storage tank 21 into the second plastering frame 22. As the cement board moves, a second layer of cement is laid on the fiber mesh cloth 34 and the first layer of cement. At this time, the first fiber cement board is made; since multiple cement boards are adjacent to each other, multiple fiber cement boards are made in sequence; finally, the multiple fiber cement boards are sent to the subsequent coating process and cutting process, so that the fiber cement boards are coated and the membrane connecting the two cement boards is cut to form pieces of fiber cement boards.
[0049] Beneficial effects of the utility model: the manufacturing device of the fiber cement board arranges the laying mechanism 30 between the two plastering mechanisms 20, so that the surface of the cement board is first coated with a first layer of cement, and then the fiber mesh cloth 34 is laid on the first layer of cement, and then the second layer of cement is coated on the fiber mesh cloth 34, so that the fiber mesh cloth 34 is fixedly laid on the cement board to form a fiber cement board; the entire application of cement liquid and the fiber mesh cloth 34 are automatically completed, so that the application thickness of the cement liquid can be controlled, and because the cement boards are next to each other, the application of cement and the laying of the fiber mesh cloth 34 can be carried out continuously, thereby improving work efficiency.
[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
