Detailed implementation manners

[0038] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] Referring to Figures 1 - 11 : The present invention provides a technical solution: a foamed board, including a foamed board body 1, a polyurethane coating layer 7 is fixedly arranged on the outer wall of the foamed board body 1, a silicone coating layer 8 is fixedly arranged on the outer wall of the polyurethane coating layer 7, and the foamed board body 1 includes the following raw materials in parts by weight:

[0040] 10 - 15 parts of PVC resin, 5 - 10 parts of plasticizer, 8 - 16 parts of foaming agent, 10 - 20 parts of stabilizer and 15 - 20 parts of filler.

[0041] In this embodiment: The polyurethane coating layer 7 can form a tough protective film on the surface of the foamed board body 1, effectively preventing the erosion of chemical substances on the foamed board body 1 and increasing the corrosion resistance of the foamed board body 1. The silicone coating layer 8 has good high-temperature resistance and certain elasticity, can resist a certain degree of wear, and improves the high-temperature resistance and wear resistance of the foamed board body 1.

[0042] The manufacturing process of the foamed board includes the following steps:

[0043] Step 1. Raw material preparation and mixing: Prepare raw materials such as PVC resin, plasticizer, foaming agent, stabilizer and filler. Put the weighed raw materials into a high-speed mixer and stir and mix them to make the raw materials fully mixed evenly to obtain a mixed material;

[0044] Step 2. Extrusion molding: Put the mixed material into an extruder. Through the high temperature and pressure in the extruder, the material is melted and formed into a uniform melt, and the melt is extruded through a die to form a foamed board;

[0045] Step 3. Cooling and shaping: A cooling mechanism quickly cools the extruded foamed board to solidify the foamed board;

[0046] Step 4. Cutting and trimming: The solidified foamed board is conveyed to a cutting mechanism 4 through a roller conveyor 3 on a bottom plate 2. The cutting mechanism 3 trims and cuts the two sides of the foamed board, and cuts the foamed board into foamed board bodies 1 of different sizes. During the cutting process of the foamed board, a dust removal mechanism 6 cleans the debris generated by cutting. After cutting, through a waste collection mechanism 5, the cut waste is recycled and processed;

[0047] Step 5. Processing: The outer surface of the foamed board body 1 is painted through a painting machine to improve the performance of the foamed board body 1.

[0048] In this embodiment: The roller conveyor 3 is installed on the top of the outer wall of the bottom plate 2. Through the roller conveyor 3, it is used to convey the cured foamed plates, so as to facilitate the cutting mechanism 4 to continuously and efficiently cut the cured foamed plates, thereby improving the production efficiency. Through the cutting mechanism 4, the cured foamed plates can be trimmed and cut, and can flexibly meet the cutting requirements of foamed board bodies 1 of different sizes, further improving the production flexibility. Through the waste collection mechanism 5, the waste generated during the cutting process can be automatically collected, reducing the workload of manual cleaning and at the same time reducing the environmental treatment cost. Through the dust removal mechanism 6, the debris generated during the cutting of the foamed plates can be removed, avoiding the interference of debris accumulation on the equipment, thereby improving the cutting efficiency and accuracy, being able to keep the working environment clean, and reducing the impact of debris on the health of operators.

[0050] In this embodiment: Through the cutting mechanism 4, the cured foamed plates can be trimmed and cut, and can flexibly meet the cutting requirements of foamed board bodies 1 of different sizes, further improving the production flexibility. Through the trimming component on the mounting frame 401, the cured foamed plates can be trimmed to remove the uneven parts at the edges of the foamed plates, making the edges of the foamed plates neater and smoother, thereby improving the overall aesthetics of the product. Through the cutting component, the foamed plates can be cut to cut out foamed board bodies 1 of different sizes. Through the switching component, the trimming component and the cutting component can be quickly switched from the trimming mode to the cutting mode without replacing the tool or making complex adjustments, reducing manual intervention, thereby significantly reducing the tool change time and being able to quickly switch between different cutting requirements, improving the production efficiency of the foamed board body 1.

[0051] Specifically, the edge trimming component includes an edge trimming frame 402, two fixed platforms 403, two edge trimming knives 404, a first bidirectional threaded rod 405, and a first forward and reverse motor 406.

By the telescopic frame 608 moving within the rotating frame 601 and cooperating with the spring 609, the brush cylinder 610 on one of the dust removal cylinders 607 can closely adhere to the foamed board body 1 to facilitate the cleaning of the surface of the foamed board body 1. A control valve is provided on each dust removal pipe 613. Through each dust removal head 612, it is convenient to clean the debris generated by the trimming knife 404 cutting the foamed board. The power sources of the dust collector 611, the fourth reversible motor 504, the third reversible motor 415, the second reversible motor 411, the first reversible motor 406, and the roller conveyor 3 are from an external power source, which should be electrically connected to the external power source. The internal circuit principle structure belongs to the common knowledge of those skilled in the art and will not be introduced in detail here. Its model can be selected according to the actual usage situation.

[0066] The following is a detailed description of the usage method of the foamed board and its manufacturing process provided by the embodiments of the present invention. The usage method includes the following steps: Step 1, raw material preparation and mixing: Prepare raw materials such as PVC resin, plasticizer, foaming agent, stabilizer, and filler. Put the weighed raw materials into a high-speed mixer and stir and mix them to make the raw materials fully and evenly mixed to obtain a well-mixed material; Step 2, extrusion molding: Put the well-mixed material into an extruder. Through the high temperature and pressure in the extruder, the material is melted and formed into a uniform melt. The melt is extruded through a die to form a foamed board; Step 3, cooling and shaping: The cooling mechanism quickly cools the extruded foamed board to solidify the foamed board; Step 4, cutting and trimming: The solidified foamed board is conveyed to the cutting mechanism 4 by the roller conveyor 3 on the bottom plate 2. The cutting mechanism 4 trims and cuts the two sides of the foamed board and cuts the foamed board into foamed board bodies 1 of different sizes. During the cutting process of the foamed board, the dust removal mechanism 6 cleans the debris generated by cutting. After cutting, through the waste collection mechanism 5, the waste after cutting is recycled. According to the thickness of the foamed board, the third forward and reverse motor 415 is started. The third forward and reverse motor 415 drives the second bidirectional threaded rod 414 to rotate, which can make the two moving blocks 416 approach or move away from each other, can simultaneously adjust the position height of the trimming knife 404 and the cutting knife 410, and can adjust the cutting depth of the trimming knife 404 and the cutting knife 410 according to the thickness of the foamed board, so as to solve the problem of insufficient cutting depth resulting in incomplete trimming or cutting. Then start the first forward and reverse motor 406. The first forward and reverse motor 406 drives the first bidirectional threaded rod 405 to rotate, driving the two fixed platforms 403 to approach each other, and can adjust the distance between the two trimming knives 404. According to the production requirements of the foamed board body 1, adjust the width of the waste edge cutting of the foamed board. After adjustment, the fixed foamed board is conveyed to the lower part of the trimming frame 402 by the roller conveyor 3. The trimming knife 404 cuts the two sides of the foamed board to remove the uneven parts on the edge of the foamed board. After the trimming of the foamed board is completed, the roller conveyor 3 continues to convey it to the lower part of the cutting frame 407. When the foamed board reaches the position to be cut, the roller conveyor 3 stops conveying. Start the second forward and reverse motor 411. The second forward and reverse motor 411 drives the rotating plate 412 to rotate, which can change the positions of the two moving blocks 416. Each moving block 416 pulls each first connecting rod 417 to move, and each first connecting rod 417 pulls each connecting piece 418 to move, so that the trimming frame 402 rises and the trimming knife 404 leaves the foamed board, while the cutting frame 407 drives the cutting knife 410 to descend, so as to facilitate the cutting knife 410 to cut the foamed board. The cylinder 408 drives the mounting table 409 to move, so that the cutting knife 410 continues to cut the foamed board and cuts it into the foamed board body 1. After cutting, start the fourth forward and reverse motor 504. The fourth forward and reverse motor 504 drives one of the third bidirectional threaded rods 505 to rotate,Synchronously rotate another third bidirectional threaded rod 505 to drive the movable frame 507 to move on the guide rod 509, so that one end of each second connecting rod 508 is driven by the movable frame 507 to move, and the other end of the second connecting rod 508 pulls the support table 502, causing the support table 502 to rotate on the support frame 501, and the cut waste material to fall into the collection box 503, enabling the automatic collection of the waste material generated during the cutting process, reducing the workload of manual cleaning, and at the same time reducing the environmental treatment cost. During the cutting process, turn on the dust collector 611, and through the dust removal head 612 on the fixed table 403, the debris generated by the cutting edge knife 404 cutting the foamed board can be cleaned. When switching to the cutting knife 410 to cut the foamed board, the connecting piece 418 on the cutting frame 407 drives the rack 602 to move, which can drive the gear 603 to drive the movable shaft 604 to rotate on the mounting frame 401. Cooperating with the two second transmission wheels 605 and the second transmission belt 606, the rotating frame 601 can be rotated on the mounting frame 401, capable of changing the position of each dust removal cylinder 607. The dust removal cylinder 607 without the brush cylinder 610 can closely adhere to and press the foamed board and the waste edge, increasing the stability of the foamed board cutting, improving the cutting accuracy, ensuring the quality of the foamed board body 1. Through the dust collector 611, the dust removal pipe 613, and the dust removal cylinder 607 without the brush cylinder 610, the debris generated by the cutting knife 410 cutting the foamed board can be cleaned. When switching to the cutting edge knife 404, the dust removal cylinder 607 sleeved with the brush cylinder 610 can approach the cut foamed board body 1, and through the spring 609, the dust removal cylinder 607 sleeved with the brush cylinder 610 is closely attached to the foamed board body 1. When the roller conveyor 3 conveys the foamed board body 1, the dust removal cylinder 607 sleeved with the brush cylinder 610 can further clean the surface of the foamed board body 1 to avoid affecting the subsequent processing of the foamed board body 1 and improve the overall performance of the product; Step Five: Processing: Apply paint to the outer surface of the foamed board body 1 through a painting device, so that a polyurethane coating layer 7 and a silicone coating 8 are sequentially attached to the surface of the foamed board body 1 to improve the performance of the foamed board body 1.,

[0067] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.,
