Description

Technical Field

[0001] The present invention belongs to the technical field of fiber cement board production, and in particular relates to a fiber reinforced cement board forming device and a forming method. Background Art

[0002] Fiber cement board is a building material primarily made of cement, fiber, and other reinforcing materials. These fibers typically include mineral fibers (such as asbestos or non-asbestos fibers), synthetic fibers, or natural organic fibers (such as wood fibers). The addition of fibers increases the board's strength and toughness, making it more durable and less prone to cracking.

[0003] The manufacturing process of fiber cement board includes multiple steps such as pulping, forming, pressing and curing. In the forming process, the fiber cement board 1 and the template 2 are usually stacked alternately. Figure 1 As shown, the presence of the template 2 can play an isolating role during the pressing process, preventing adjacent fiber cement boards 1 from sticking together.

[0004] After the forming step, the curing step begins. The curing step is generally performed by placing the fiber cement board 1 in a container of an autoclave so that high-pressure steam accelerates the rapid hardening of the board and enhances its mechanical properties.

[0005] Therefore, after the forming process and before entering the curing step, the alternately stacked fiber cement boards 1 and formwork 2 need to be separated by external force. However, a certain adsorption force will be generated between the fiber cement boards 1 and formwork 2 after pressing and draining, which makes it difficult to operate and the separation efficiency is low during the process of separating adjacent fiber cement boards 1 and formwork 2 one by one. Summary of the Invention

[0006] The present invention aims to solve the problems in the prior art and proposes the following technical solutions:

[0007] The present invention provides a fiber reinforced cement board forming device, comprising: a pressing plate and a base, on which fiber cement boards and templates are alternately stacked, and further comprising:

[0008] A separation assembly is provided on the base and includes a plurality of inserting plates and springs provided between adjacent inserting plates. The inserting plates are embedded in the gaps between adjacent templates when the pressing plate is pressed and formed. When the pressing plate is lifted, the springs are deformed to increase the distance between adjacent inserting plates, thereby separating the fiber cement board and the template.

[0009] A vertical pole is provided on the base, and the inserting plate is movably provided on the vertical pole, and the inserting plate can move along the axial direction of the vertical pole.

[0010] As a preferred embodiment of the above technical solution, it further includes a mounting frame movably arranged on the base plate, the mounting frame is located on both sides of the fiber cement board and the template, and the vertical pole is arranged on the mounting frame.

[0011] As a preferred embodiment of the above technical solution, the vertical pole is fixedly connected to the mounting frame, the plug plate is sleeved on the outside of the vertical pole, and a spring 1 is provided between adjacent plug plates, the spring 1 supports and separates adjacent plug plates, and before the pressure plate is press-formed, the plug plate is embedded in the gap between adjacent templates; during the pressure plate press-forming, the plug plate moves downward synchronously with the pressing action of the pressure plate and compresses the spring 1; after the pressure plate is press-formed, the adjacent plug plates are bounced off during the resetting process of the spring 1 to separate the adjacent templates.

[0012] As a preferred embodiment of the above technical solution, the vertical pole is rotatably connected to the mounting frame, the plug plate is sleeved on the outside of the vertical pole, and a distance block is fixedly sleeved on the vertical pole and located between adjacent plug plates. A mounting groove is provided on the top of the distance block, and a top block is movably embedded in the mounting groove by a spring. The top block has at least a first state and a second state as the vertical pole rotates:

[0013] First state: the top block compresses spring 2 and is embedded in the mounting groove, and the position of the top block is locked;

[0014] Second state: the second spring is reset, the top of the top block extends out of the mounting slot, and the top block is unlocked;

[0015] It also includes a limiting structure, which limits the plug plate and the top block to rotate synchronously with the vertical pole;

[0016] In the first state, the inserting plate is embedded in the gap between adjacent templates after the pressing plate is pressed and formed. After the inserting plate is inserted into the gap between adjacent templates, it switches to the second state, and the fiber cement board and the template are separated.

[0017] As a preferred embodiment of the above technical solution, a pin body is provided on the side of the top block close to the vertical pole, and an L-shaped limit groove is provided on the vertical pole at a position corresponding to the pin body, and the limit groove includes a vertical section and a horizontal section. When the pin body is located in the horizontal section, the top block is in a first state, and when the pin body is located in the vertical section, the top block is in a second state.

[0018] As a preferred embodiment of the above technical solution, extension plates are further provided on both sides of the pressing plate at positions corresponding to the inserting plates.

[0019] As a preferred embodiment of the above technical solution, the limiting structure includes a guide rod, which is arranged on the mounting frame and parallel to the vertical rod, and the inserting plate and the distance block are movably mounted on the guide rod.

[0046] The placement table 26 corresponds to the upper and lower positions of the pressing plate 12, and the hydraulic cylinder 13 drives the pressing plate 12 to move downward in the vertical direction to achieve the pressing action of the alternately stacked fiber cement boards 1 and templates 2;

[0047] The placement table 26 is used to support the alternately stacked fiber cement boards 1 and templates 2, and to adjust the height of the alternately stacked fiber cement boards 1 and templates 2; after the inserting plates 31 on both sides gradually approach the alternately stacked fiber cement boards 1 and templates 2, the inserting plates 31 are inserted into the gaps between adjacent templates 2 to play the role of pre-separating adjacent templates 2.

[0048] The mounting frame 22 can be driven by the electric push rod 25 to move closer to or farther away from the alternately stacked fiber cement boards 1 and templates 2 .

[0049] The sliding cooperation between the pulley 221 and the slide groove 211 ensures the stability of the mounting frame 22 during movement and reduces sliding friction.

[0050] Example 2

[0051] like Figure 4 、 Figure 5 As shown, Figure 4 Shown is an overall schematic diagram of Example 2; Figure 5 The figure shows a schematic diagram of the structure of the base and the separation component in Example 2;

[0053] The pressing assembly includes a frame 11, a hydraulic cylinder 13 is provided on the frame 11, and a pressing plate 12 is provided at the output end of the hydraulic cylinder 13. The hydraulic cylinder 13 drives the pressing plate 12 to move in the vertical direction;

[0055] The separation assembly 30 includes side plates 24 provided on the bottom plate 21 and located on both sides of the product, an electric push rod 25 is provided at one end of the side plates 24 close to each other, a mounting bracket 22 is provided at the output end of the electric push rod 25, a vertical rod 23 is provided at one end of the mounting bracket 22 close to each other, a plurality of inserting plates 31 are arranged at intervals on the vertical rod 23, the inserting plates 31 are movably sleeved on the vertical rod 23, the inserting plates 31 can move along the axial direction of the vertical rod 23, and a spring 41 is provided between adjacent inserting plates 31, the spring 41 supports and separates each inserting plate 31, before the pressing plate 12 is press-formed, the inserting plates 31 are embedded in the gap between adjacent templates 2; during the press-forming of the pressing plate 12, the inserting plates 31 move downward synchronously with the pressing action of the pressing plate 12 and compress the spring 41; after the press-forming of the pressing plate 12, the adjacent inserting plates 31 are bounced off during the resetting process of the spring 41 to separate the adjacent templates 2;

[0056] The structure is different from that of the first embodiment in that the separation assembly 30 and the inserting plate 31 are movably sleeved on the vertical rod 23, and a spring 41 is provided between adjacent inserting plates 31;

[0057] Through the movable inserting plates 31 and springs 141, multiple springs 141 support and separate multiple inserting plates 31.

[0062] The pressing assembly includes a frame 11, a hydraulic cylinder 13 is provided on the frame 11, and a pressing plate 12 is provided at the output end of the hydraulic cylinder 13. The hydraulic cylinder 13 drives the pressing plate 12 to move in the vertical direction;

[0065] like Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 As shown, Figure 7 The structure of the base and the separation component in Example 3 is shown. Figure 1 ; Figure 8 Shown is Figure 7 A schematic diagram of the structure at center A;

[0066] Figure 9 The structure of the base and the separation component in Example 3 is shown. Figure 2 ; Figure 10 Shown is

[0067] Figure 9 A magnified schematic diagram of the structure at point B in the middle; Figure 11 What is shown is a schematic diagram of the structure of the upper limit slot of the vertical pole;

[0068] The vertical rod 23 is rotatably arranged on the mounting frame 22, and the plug plate 31 is movably sleeved on the vertical rod 23. A distance block 51 is fixedly sleeved on the vertical rod 23 and located between adjacent plug plates 31. A mounting slot 52 is opened at the top of the distance block 51, and a plurality of springs 53 are arranged in the mounting slot 52. One end of the spring 53 is connected to the bottom of the mounting slot 52, and the other end is connected to a top block 54 sleeved on the vertical rod 23. The top block 54 is movably embedded in the mounting slot 52. A pin body 55 is provided on the side of the top block 54 close to the vertical rod 23. An L-shaped limiting slot 56 is provided at the position corresponding to the pin body 55 on the vertical rod 23. The limiting slot 56 includes a vertical section 561 and a horizontal section 562. A motor 57 is also provided at the bottom of the mounting frame 22. The output end of the motor 57 is connected to the bottom of the vertical rod 23. The motor 57 can drive the vertical rod 23 to rotate. The movably arranged vertical rod 23 makes the top block 54 have at least a first state or a second state;

[0069] The first state is Figure 9 、 Figure 10 As shown;

[0070] First state: the top block 54 is embedded in the installation groove 52, the second spring 53 is compressed, and the pin body 55 is located in the horizontal section 562 of the limiting groove 56. The top block 54 cannot slide up and down outside the vertical rod 23, that is, the top block 54 is locked.

[0071] The second state is Figure 7 、 Figure 8 As shown;

[0072] Second state: the top block 54 extends out of the mounting slot 52, the second spring 53 is in a natural state, the pin 55 is located in the vertical section 561 of the limiting slot 56, and the top block 54 can slide up and down outside the vertical rod 23, that is, the top block 54 is in the unlocked state;

[0073] The positioning structure further includes a limiting structure, which limits the insertion plate 31 and the top block 54 to rotate synchronously with the vertical rod 23; the limiting structure includes a guide rod 42, which is arranged on the mounting frame 22 and parallel to the vertical rod 23, and the insertion plate 31 and the distance block 51 are both movably mounted on the guide rod 42;

[0074] Extension plates 58 are further provided on both sides of the pressing plate 12 at positions corresponding to the inserting plates 31;

[0075] When the top block 54 is in the first state, that is, the distance block 51 and the top block 54 are fixed, the distance block 51 and the top block 54 separate the plugboards 31 and can ensure that the distance between the plugboards 31 is constant;

[0076] Specifically, the working principle of this implementation is as follows:

[0077] During compression molding:

[0078] Before the pressing plate 12 presses the fiber cement board 1 into shape: the top block 54 is in the second state, that is, the top block 54 extends out of the mounting slot 52, the second spring 53 is in the natural state, the pin 55 is located in the vertical section 561 of the limiting slot 56, and the top block 54 can slide downward outside the vertical rod 23;

[0079] When the pressing plate 12 is pressing and forming the fiber cement board 1, the pressing plate 12 moves downward to press the alternately stacked fiber cement boards 1 and the template 2, while the extension plate 58 presses the inserting plate 31 downward; at this time, the inserting plate 31 presses the top block 54 downward, so that each top block 54 presses the spring 2 53 downward until the top block 54 is embedded in the installation groove 52, and at the same time, the pin body 55 of the top block 54 is located in the vertical section 561 of the limiting groove 56 near the end of the horizontal section 562, and then the motor 57 is turned on, and the motor 57 drives the vertical rod 23 to rotate, so that the pin body 55 enters the horizontal section 562, and the top block 54 is locked, switching to the first state;

[0080] After the pressing plate 12 presses and forms the fiber cement board 1, the pressing plate 12 moves upward and leaves the alternately stacked fiber cement board 1 and template 2. At this time, the inserting plate 31 approaches the alternately stacked fiber cement board 1 and template 2 and is inserted into the gap between the adjacent templates 2. Then the motor 57 is turned on again to drive the vertical rod 23 to rotate in the opposite direction, so that the pin body 55 enters the vertical section 561. As the pin body 55 slides in the vertical section 561, the spring 2 53 is reset, driving the top block 54 to pop out of the installation groove 52, thereby increasing the interval between adjacent inserting plates 31. The cooperation of the spring 2 53 and the top block 54 provides a force to pre-separate the fiber cement board 1 and the template 2, thereby facilitating the subsequent direct suction of the template 2 and the fiber cement board 1 by the negative pressure adsorption gripper.

[0081] A pulley 221 is provided at the bottom end of the mounting frame 22 , and a sliding groove 211 for the pulley 221 to slide is provided at the top end of the bottom plate 21 . The pulley 221 is in sliding engagement with the sliding groove 211 .

[0085] S2, making the insert plate 31 embedded in the gap between adjacent templates 2 during press forming;

[0086] S3. After forming, the pressing plate 12 is removed, and the spring is deformed to increase the distance between adjacent inserting plates 31, thereby pre-separating the fiber cement board 1 and the template 2.

[0087] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
