Description

Technical Field

[0001] This utility model belongs to the field of calcium silicate board production technology, specifically relating to an integrated production line for fiber-reinforced calcium silicate boards. Background Technology

[0002] As a new type of green building material, fiber-reinforced calcium silicate board requires several key processes in its industrial production, including raw material preparation, slurry forming, roll compaction, wet blank cutting, and steam curing. Currently, the mainstream production lines in the industry adopt a modular, segmented layout, mainly consisting of four functional units: forming production line, cutting production line, drying production line, and steam curing production line.

[0003] In this process, the forming line and cutting line, as core upstream processes, are generally designed as separate units in existing technologies. This means that the roll-formed slabs are transported via a conveyor to a separately located cutting section for edge trimming. This discrete layout results in low equipment integration during actual operation. This is because the forming section requires large equipment such as a headbox, vacuum belt dewatering machine, and forming roll cylinders, while the cutting section requires a separate waterjet cutting system, positioning platform, and waste recycling device. A 5-10 meter long slab buffer conveyor belt needs to be reserved between the two sections, directly causing the total production line length to exceed 30 meters. This not only significantly increases the plant construction cost but also, due to the excessively long equipment spacing, causes longitudinal bending deformation during slab transport, directly affecting subsequent cutting accuracy. Secondly, because the forming and cutting lines are separate, the slabs need to be repositioned by a servo positioning mechanism when entering the cutting section. This process is time-consuming, and the positioning accuracy is affected by conveyor belt vibration.

[0004] To address the aforementioned issues, this utility model proposes an integrated molding and cutting production line for fiber-reinforced calcium silicate boards. By integrating molding and cutting processes, a continuous production unit is constructed, forming a compact production line layout that shortens equipment length and reduces floor space. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated production line for fiber-reinforced calcium silicate boards, comprising a forming roller, a roller press table, and a vacuum belt dewatering machine. A headbox is installed at the filter cloth feeding end of the vacuum belt dewatering machine. The roller press table is installed at the filter cloth unloading end of the vacuum belt dewatering machine. The forming roller is installed on the top end face of the roller press table. A belt conveyor is installed at the filter cloth unloading end of the vacuum belt dewatering machine on one side of the roller press table. A support frame is provided on the outside of the forming roller, and the bottom of the support frame is fixed to the frame of the vacuum belt dewatering machine and the roller press table. A first slab cutting assembly is installed on the feeding side of the forming roller, and a second slab cutting assembly is installed on the discharging side of the forming roller. An edge trimming assembly is installed on one side of the support frame next to the second slab cutting assembly.

[0006] As a preferred embodiment of this utility model, the conveying direction of the belt conveyor is the same as the conveying direction of the filter cloth of the vacuum belt dewatering machine.

[0007] As a preferred technical solution of this utility model, the first slab cutting assembly includes a rotating shaft, the two ends of the rotating shaft are rotatably connected to the two sides of the support frame, the shaft body of the rotating shaft is fixed with a first cutting blade, and a stepping drive mechanism is installed at one end of the rotating shaft.

[0008] As a preferred technical solution of this utility model, the second slab cutting assembly includes an eccentric shaft, the two ends of which are rotatably connected to both sides of the roller press table. A second cutter is fixed on one side of the eccentric shaft, and a cutting cylinder is installed on both ends of the eccentric shaft. The output end and the cylinder body of the cutting cylinder are rotatably connected to one side of the eccentric shaft and the roller press table, respectively.

[0009] As a preferred technical solution of this utility model, the edge trimming component includes a circular saw and a lifting cylinder. The circular saw is arranged on both sides of the belt conveyor. The cylinder body of the lifting cylinder is fixed on the support frame. A bracket is fixed to the output end of the lifting cylinder. A pressure cylinder is rotatably connected to the bottom end of the bracket.

[0010] As a preferred embodiment of this utility model, collection boxes are provided on both sides of the belt conveyor frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention integrates the molding and cutting processes, eliminating the 5-10 meter long slab buffer conveyor belt between the molding and cutting lines found in traditional split designs. This significantly shortens the overall length of the production line and allows for a more compact equipment layout. This not only reduces the need for factory space and lowers construction costs, but also reduces connection and maintenance costs between equipment due to the shorter equipment spacing, thus improving the company's economic efficiency. Furthermore, the slab does not require secondary positioning throughout the production process, avoiding positioning errors caused by conveyor belt vibration affecting the servo positioning mechanism and greatly improving cutting accuracy. Simultaneously, the continuous production unit reduces the risk of longitudinal bending deformation of the slab during transport, further ensuring the accuracy of product dimensions and the stability of slab quality, thereby improving product yield.

[0019] Example

[0020] Please see Figure 1 This utility model provides the following technical solution: an integrated production line for fiber-reinforced calcium silicate boards, including a forming roller cylinder 1, a roller press table 13, and a vacuum belt dewatering machine 2. A headbox 4 is installed at the filter cloth feeding end of the vacuum belt dewatering machine 2. The roller press table 13 is installed at the filter cloth unloading end of the vacuum belt dewatering machine 2. The forming roller cylinder 1 is installed on the top end face of the roller press table 13. A belt conveyor 3 is installed on one side of the filter cloth unloading end of the vacuum belt dewatering machine 2, located on the roller press table 13. A support frame 5 is provided on the outside of the forming roller cylinder 1. The bottom of the support frame 5 is fixed on the frame of the vacuum belt dewatering machine 2 and the roller press table 13. A first slab cutting assembly is installed on the feeding side of the forming roller cylinder 1, and a second slab cutting assembly is installed on the discharging side of the forming roller cylinder 1. An edge trimming assembly is installed on one side of the support frame 5 located on the second slab cutting assembly.

[0021] Please see Figure 1 In order to ensure a smooth transition of the slab between different devices and avoid displacement or deformation of the slab due to inconsistent conveying directions, thereby improving the stability and continuity of the production process, in this embodiment, as a preferred technical solution of the present invention, the conveying direction of the belt conveyor 3 is the same as the conveying direction of the filter cloth of the vacuum belt dewatering machine 2.

[0022] Please see Figure 3In order to accurately control the cutting position of the front end of the slab, the rotation angle of the rotating shaft 6 is precisely adjusted by the stepper drive mechanism, thereby ensuring the consistency of the front end length of the slab when the first cutter 7 cuts, and meeting the strict requirements of the starting size for producing slabs of different specifications. In this embodiment, as a preferred technical solution of the present invention, the first slab cutting assembly includes a rotating shaft 6, the two ends of the rotating shaft 6 are rotatably connected to the two sides of the support frame 5, the first cutter 7 is fixed on the shaft body of the rotating shaft 6, and a stepper drive mechanism is installed at one end of the rotating shaft 6.

[0023] Please see Figure 2 In order to achieve flexible and efficient cutting operation on the rear end of the slab, in this embodiment, as a preferred technical solution of the present invention, the second slab cutting assembly includes an eccentric shaft 9, the two ends of the eccentric shaft 9 are rotatably connected to both sides of the roller press table 13, a second cutter 10 is fixed on one side of the eccentric shaft 9, and a cutting cylinder 11 is installed on both ends of the eccentric shaft 9. The output end and the cylinder body of the cutting cylinder 11 are rotatably connected to one side of the eccentric shaft 9 and the roller press table 13, respectively.

[0024] Please see Figure 1 In order to prevent the slab from moving during the cutting process and ensure cutting accuracy when trimming the edge of the slab, and to efficiently remove the excess parts on both sides of the slab to ensure that the slab width meets the standard and improve product quality, in this embodiment, as a preferred technical solution of the present invention, the edge trimming component includes a circular saw 12 and a lifting cylinder 15. The circular saw 12 is set on both sides of the belt conveyor 3, the cylinder body of the lifting cylinder 15 is fixed on the support frame 5, the output end of the lifting cylinder 15 is fixed with a bracket 16, and the bottom end of the bracket 16 is rotatably connected to a pressure cylinder 8.

[0025] Please see Figure 1 In order to effectively collect the waste generated during the edge trimming of the slab, in this embodiment, as a preferred technical solution of the present invention, collection boxes 14 are provided on both sides of the frame of the belt conveyor 3.

[0026] In this embodiment, the headbox 4 is a known technology widely used in daily life, generally consisting of a distributor, a weir, and a weir plate. The prepared mixed slurry is transported to the distributor through a pipeline. The distributor's function is to evenly distribute the slurry into the weir, ensuring a uniform flow rate and stable flow when the slurry enters the weir. The weir buffers and stabilizes the slurry, maintaining a relatively constant liquid level to ensure uniform discharge later. After the slurry stabilizes in the weir, it flows out through an adjustable-height weir plate. The height and shape of the weir plate determine the thickness and speed of the flowing slurry. Operators can precisely adjust the weir plate parameters according to the required slab thickness and forming process requirements, thereby evenly delivering the prepared raw materials to the filter cloth feeding end of the vacuum belt dewatering machine 2.

[0027] In summary, in the integrated production line for fiber-reinforced calcium silicate boards, firstly, during the raw material processing stage, the prepared raw materials are evenly fed to the filter cloth feeding end of the vacuum belt dewatering machine 2 via the headbox 4. The vacuum belt dewatering machine 2 utilizes the vacuum suction principle to quickly remove moisture from the raw materials, allowing the board blank to be initially formed. The board blank processed by the vacuum belt dewatering machine 2 is then output from the filter cloth unloading end of the vacuum belt dewatering machine 2 to the roller press table 13. At this time, the forming roller 1 located on the top end face of the roller press table 13 begins to work, further compacting the board blank and improving its density and structural strength.

[0028] During the slab forming process, the first slab cutting assembly plays a crucial role. The two ends of the rotating shaft 6 are rotatably connected to the sides of the support frame 5. A stepping drive mechanism is installed at one end of the rotating shaft 6, driving it to rotate intermittently at a set step distance. The first cutter 7, fixed to the shaft, rotates accordingly, performing a transverse cut on the front end of the slab during the slab feeding process to determine the initial length of the slab and ensure the consistency of the front end dimensions of each slab.

[0029] After being rolled by the forming roller 1, the slab is wound around the surface of the forming roller 1. Once a suitable thickness is reached, the second slab cutting assembly begins operation. The two ends of the eccentric shaft 9 are rotatably connected to both sides of the support frame 5. The output end and cylinder body of the cutting cylinder 11 are rotatably connected to the end of the eccentric shaft 9 and the support frame 5, respectively. When the cutting cylinder 11 actuates, it pushes the eccentric shaft 9 to swing around the connection point. The second cutter 10, fixed to one side of the eccentric shaft 9, swings and descends accordingly, performing a transverse cut on the slab to determine the rear end length of the slab.

[0030] The cut slab ends fall onto the surface of the roller press table 13. Through the rear end of the vacuum belt dewatering machine 2 and the forming roller press 1, the cut slab is continuously conveyed to the surface of the belt conveyor 3. The conveying direction of the belt conveyor 3 is the same as the conveying direction of the filter cloth in the vacuum belt dewatering machine 2, ensuring a smooth transition of the slab. During the slab conveying process, the edge trimming components located on both sides of the belt conveyor 3 begin to operate. The lifting cylinder 15 is fixed to the support frame 5, and the bottom end of the bracket 16 fixed to its output end is rotatably connected to the pressure cylinder 8. The lifting cylinder 15 pushes the bracket 16 and the pressure cylinder 8 down, and the pressure cylinder 8 presses the slab tightly onto the belt conveyor 3 to prevent displacement of the slab during the cutting process. Simultaneously, the circular saw 12 starts to cut and trim the edges of the slab on both sides, removing excess scrap material to bring the slab to the specified width. The waste generated during cutting falls by gravity into the collection boxes 14 on both sides of the belt conveyor 3 frame, achieving centralized collection and recycling of waste.
