Description

Technical Field

[0001] This invention belongs to the field of polystyrene board production technology, specifically a polystyrene board production process and cutting equipment. Background Technology

[0002] Polystyrene board, also known as polystyrene foam board, is a type of board made from polystyrene resin through a special foaming process. It is lightweight, high-strength, heat-insulating, safe, and environmentally friendly, and is widely used in various fields.

[0003] The size requirements for polystyrene boards vary in different application scenarios. Therefore, some buyers will make size requests to polystyrene board manufacturers. Manufacturers use cutting equipment to cut polystyrene boards during production, thereby reducing waste caused by secondary processing of polystyrene boards by users. However, when cutting polystyrene boards with existing production and cutting equipment, the polystyrene boards are prone to displacement due to force, which leads to a decrease in cutting accuracy.

[0004] Therefore, the present invention provides a polystyrene board production process and cutting equipment. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is: a flange stamping process described in this invention, the specific steps of which are as follows: S1. Add the raw material granules mixed with foaming agent into the pre-expansion machine, and heat them with steam or hot water to make the granules expand into pre-expanded granules. S2. Let the pre-foamed granules sit for a period of time to mature, allowing air to fully penetrate into the granules. S3. The matured granules are fed into the forming machine through the fan system. Steam is added to control the time in the forming machine so that the granules melt and bond into the mold to form a board. Then, the cooling system is used to cool and solidify the board. S4. After molding, the polystyrene board is left to age for a period of time to allow the moisture and flammable foaming agent inside the board to evaporate further, thereby improving the stability and safety of the polystyrene board. S5. Finally, cut the polystyrene board using cutting equipment according to the required size and shape.

[0007] A polystyrene board cutting device is disclosed, applicable to the aforementioned polystyrene board production process. The cutting device includes a frame; a linear motor is fixedly connected to the top of the frame; an electric cylinder is fixedly connected to the output end of the linear motor; a connecting block is fixedly connected to the bottom of the output end of the electric cylinder; a cutting mechanism is installed in the middle of the connecting block; a pair of pressure rods are symmetrically arranged and rotatably connected to the bottom of the connecting block; a first spring is fixedly connected between the pair of pressure rods; a pair of second springs are symmetrically arranged and fixedly connected to the inner sidewall of the frame; and pressure tubes are fixedly connected to the bottom ends of the pair of second springs. Through this structure, the polystyrene board can be pressed during cutting, reducing the decrease in cutting accuracy caused by board misalignment. Simultaneously, the pressing force far from the cutting position is less than the pressing force near the cutting position, resulting in more concentrated pressure on the polystyrene board and further improving cutting accuracy.

[0008] Preferably, an air extractor is fixedly connected to the side wall of the frame; a filter box is fixedly connected to the side wall of the frame; the input end of the air extractor is connected to the filter box; a filter plate is fixedly connected inside the filter box; a conduit is fixedly connected to the middle of the filter box; the other end of the conduit is connected to a pressure pipe; an air inlet groove is opened on the side wall of the pressure pipe; a follow-up air inlet assembly is installed in the middle of the air inlet groove; with the above structure, some of the debris generated by cutting polystyrene boards can be cleaned, reducing the occurrence of debris residue on the processing table and reducing pollution to the working environment.

[0009] Preferably, the follow-up air intake assembly includes a diaphragm; both ends of the diaphragm are fixed to the inner ends of the pressure tube, and the diaphragm is fitted into the air intake groove; a telescopic rod is fixed to the bottom of the connecting block; a limiting post is fixed to the middle of the telescopic rod; the limiting post is located between the diaphragm and the air intake groove; through the above structure, the suction force at the cutting position can be increased, thereby further improving the cleaning effect of cutting debris, further reducing the occurrence of cutting debris residue on the processing table, and reducing pollution to the working environment.

[0010] Preferably, a pair of magnets are fixed to the inner wall of the pressure tube; the pair of magnets are located above and below the air inlet groove respectively; a pair of metal strips are fixed to the inside of the diaphragm; through the above structure, the suction force at the limiting post is further enhanced, and the cleaning effect of cutting debris is further improved.

[0011] Preferably, a collection box is slidably connected to the middle of the filter box; the collection box is located below the filter plate; a pair of limiting plates are rotatably connected to the side wall of the filter box; through the above structure, the residue of debris inside the filter box is reduced, and the cleaning effect of debris is improved.

[0012] Preferably, a limiting rod is fixed to the bottom of the magnet; the limiting rod is located between a pair of pressure rods; with the above structure, when the pressure tube is pressed again, it is ensured that the bottoms of the pair of pressure rods can expand outward rather than move closer to each other, reducing the occurrence of obstruction to the cutting saw blade.

[0013] Preferably, a scraper is fixedly connected to the top of the limiting post; the scraper is in contact with the inner wall of the pressure tube; through the above structure, the debris residue inside the pressure tube is reduced, and the debris cleaning effect is improved.

[0014] Preferably, a plurality of rotating rollers are rotatably connected to the middle of the pressure rod; the plurality of rotating rollers are located above the pressure tube; with the above structure, when the pressure rod moves along the top of the pressure tube, the sliding friction between the pressure rod and the pressure tube can be converted into rolling friction, reducing the wear of the component and improving the service life of the component.

[0015] The beneficial effects of this invention are as follows: 1.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figure 1 As shown in the embodiment of the present invention, a polystyrene board production process is described, and the specific steps of the production process are as follows: S1. Add the raw material granules mixed with foaming agent into the pre-expansion machine, and heat them with steam or hot water to make the granules expand into pre-expanded granules. S2. Let the pre-foamed granules sit for a period of time to mature, allowing air to fully penetrate into the granules. S3. The matured granules are fed into the forming machine through the fan system. Steam is added to control the time in the forming machine so that the granules melt and bond into the mold to form a board. Then, the cooling system is used to cool and solidify the board. S4. After molding, the polystyrene board is left to age for a period of time to allow the moisture and flammable foaming agent inside the board to evaporate further, thereby improving the stability and safety of the polystyrene board. S5. Finally, cut the polystyrene board using cutting equipment according to the required size and shape.

[0021] like Figures 2 to 3As shown, a polystyrene board cutting device is applicable to the aforementioned polystyrene board production process. The cutting device includes a frame 1; a linear motor 12 is fixedly connected to the top of the frame 1; an electric cylinder 13 is fixedly connected to the output end of the linear motor 12; a connecting block 14 is fixedly connected to the bottom of the output end of the electric cylinder 13; a cutting mechanism is installed in the middle of the connecting block 14; a pair of pressure rods 15 are symmetrically arranged and rotatably connected to the bottom of the connecting block 14; a first spring 16 is fixedly connected between the pair of pressure rods 15; a pair of second springs 17 are symmetrically arranged and fixedly connected to the inner sidewall of the frame 1; a pressure tube 18 is fixedly connected to the bottom end of the pair of second springs 17; during operation, the polystyrene board to be cut is placed under the pressure tube 18, and when cutting the polystyrene board, the electric cylinder 13 is activated to drive the connecting block 14. As the cutting mechanism descends, the bottom of a pair of pressure rods 15 abuts against the top of the pressure tube 18, causing the pressure tube 18 to move downwards and press against the polystyrene board. Subsequently, the polystyrene board is cut by the cutting mechanism. As the linear motor 12 moves, the cutting mechanism moves, and the pressure rods 15 move accordingly, continuously pressing against the pressure tube 18 near the cutting position. This results in the polystyrene board near the cutting position bearing a larger pressing force, while the polystyrene board far from the cutting position bears a smaller pressing force. Through this structure, the polystyrene board can be pressed during cutting, reducing the decrease in cutting accuracy caused by polystyrene board offset. At the same time, the pressing force far from the cutting position of the polystyrene board is less than the pressing force near the cutting position, and the pressure on the polystyrene board is more concentrated, which can further improve the cutting accuracy.

[0022] like Figures 2 to 5 As shown, an air extractor 2 is fixedly connected to the side wall of the frame 1; a filter box 21 is fixedly connected to the side wall of the frame 1; the input end of the air extractor 2 is connected to the filter box 21; a filter plate 22 is fixedly connected inside the filter box 21; a conduit 23 is fixedly connected to the middle of the filter box 21; the other end of the conduit 23 is connected to the pressure pipe 18; an air inlet groove 24 is opened on the side wall of the pressure pipe 18; a follow-up air inlet component is installed in the middle of the air inlet groove 24; during operation, the air extractor 2 is started to extract air, and the air near the pressure pipe 18 will enter the interior of the pressure pipe 18 through the air inlet groove 24. When the air flows, it will carry some of the debris generated during the cutting of polystyrene board into the interior of the pressure pipe 18. This debris will enter the interior of the filter plate 22 along the pressure pipe 18 and the conduit 23 and be blocked by the filter box 21. Through the above structure, some of the debris generated during the cutting of polystyrene board can be cleaned, reducing the occurrence of debris residue on the processing table and reducing pollution to the working environment.

[0023] like Figures 2 to 4As shown, the follow-up air intake assembly includes a diaphragm 3; both ends of the diaphragm 3 are fixed to the inner ends of the pressure tube 18, and the diaphragm 3 is fitted into the air intake groove 24; a telescopic rod 31 is fixed to the bottom of the connecting block 14; a limiting post 32 is fixed to the middle of the telescopic rod 31; the limiting post 32 is located between the diaphragm 3 and the air intake groove 24; during operation, as the linear motor 12 drives the cutting mechanism to move and cut the polystyrene board, the limiting post 32 moves with the connecting block 14, causing the diaphragm 3 to separate from the air intake groove 24 at the limiting post 32, thereby allowing more external air to be drawn into the pressure tube 18 from the limiting post 32, increasing the suction force at the cutting position. Through the above structure, the suction force at the cutting position can be increased, thereby further improving the cleaning effect of cutting debris, further reducing the occurrence of cutting debris remaining on the processing table, and reducing pollution to the working environment.

[0024] like Figures 2 to 4 As shown, a pair of magnets 4 are fixed to the inner wall of the pressure tube 18; the pair of magnets 4 are located above and below the air inlet groove 24 respectively; a pair of metal strips 41 are fixed to the inside of the diaphragm 3; during operation, the diaphragm 3 away from the limiting post 32 will adhere to the inner wall of the pressure tube 18 due to the attraction of the magnets 4 and the metal strips 41, and block this part of the air inlet groove 24, thereby further increasing the suction force at the limiting post 32 and further improving the cleaning effect of cutting debris.

[0025] like Figures 2 to 5 As shown, a collection box 5 is slidably connected to the middle of the filter box 21; the collection box 5 is located below the filter plate 22; a pair of limiting plates 51 are rotatably connected to the side wall of the filter box 21; during operation, some liquid is added inside the collection box 5, and the debris entering the filter box 21 through the conduit 23 will be impacted by the airflow onto the liquid surface inside the collection box 5 and be wetted, so that the debris is less likely to fly away with the airflow inside the filter box 21 or adhere to the bottom of the filter plate 22, thereby reducing the residue of debris inside the filter box 21 when the collection box 5 is pulled out to clean the debris, and improving the cleaning effect of debris.

[0026] like Figure 3 As shown, the bottom of the magnet 4 is fixedly connected to a limiting rod 6; the limiting rod 6 is located between a pair of pressure rods 15; during operation, when the connecting block 14 rises with the retraction of the electric cylinder 13, the pair of pressure rods 15 no longer press the pressure tube 18, and the pair of pressure rods 15 will approach each other under the pull of the first spring 16. After the pair of pressure rods 15 approach each other to a certain extent, they will be blocked by the limiting rod 6, so that the distance between the bottom of the pair of pressure rods 15 is greater than the distance between the top, thereby ensuring that when the pressure tube 18 is pressed again, the bottom of the pair of pressure rods 15 can expand outward rather than approach each other, reducing the occurrence of obstruction to the cutting saw blade.

[0027] like Figures 2 to 4 As shown, a scraper 7 is fixedly connected to the top of the limiting post 32; the scraper 7 is in contact with the inner wall of the pressure tube 18; during operation, as the limiting post 32 moves, the scraper 7 will scrape off the debris attached to the inner wall of the pressure tube 18, reducing the debris residue inside the pressure tube 18 and improving the debris cleaning effect.

[0028] like Figure 3 As shown, a plurality of rotating rollers 8 are rotatably connected to the middle of the pressure rod 15; the plurality of rotating rollers 8 are located above the pressure tube 18; through the above structure, when the pressure rod 15 moves along the top of the pressure tube 18, the sliding friction between the pressure rod 15 and the pressure tube 18 can be converted into rolling friction, thereby reducing the wear of the component and improving the service life of the component.

[0029] During operation, the polystyrene board to be cut is placed under the pressure tube 18. When cutting the polystyrene board, the electric cylinder 13 is activated, causing the connecting block 14 and the cutting mechanism to descend. As the connecting block 14 descends, the bottoms of a pair of pressure rods 15 press against the top of the pressure tube 18, causing the pressure tube 18 to move downwards and press against the polystyrene board. The polystyrene board is then cut by the cutting mechanism. As the linear motor 12 moves, driving the cutting mechanism, the pressure rods 15 move accordingly and continuously press against the pressure tube 18 near the cutting position, causing the polystyrene board near the cutting position to bear a greater compressive force, while the board further away... The polystyrene board away from the cutting position experiences a smaller compressive force. The air extraction fan 2 is activated to extract air. Air near the pressure pipe 18 enters the interior of the pressure pipe 18 through the air inlet groove 24. As the air flows, it carries some debris generated during the polystyrene board cutting into the pressure pipe 18. This debris then travels along the pressure pipe 18 and the guide tube 23 into the filter plate 22 and is blocked by the filter box 21. As the linear motor 12 operates, it drives the cutting mechanism to move and cut the polystyrene board. The limiting post 32 moves with the connecting block 14, causing the diaphragm 3 to separate from the air inlet groove 24 at the limiting post 32, thus allowing the outer... A significant amount of air can be drawn into the pressure tube 18 from the limiting post 32, increasing the suction force at the cutting position. The diaphragm 3, far from the limiting post 32, will be attracted to the inner wall of the pressure tube 18 by the magnet 4 and the metal strip 41, blocking this part of the air inlet groove 24, thereby further increasing the suction force at the limiting post 32. Some liquid is added inside the collection box 5. The debris entering the filter box 21 through the conduit 23 will be impacted by the airflow and wetted on the liquid surface in the collection box 5, making it difficult for the debris to fly away with the airflow inside the filter box 21 or adhere to the bottom of the filter plate 22. This reduces the amount of debris remaining inside the filter box 21 when the collection box 5 is pulled out to clean the debris. When the connecting block 14 rises with the retraction of the electric cylinder 13, the pair of pressure rods 15 no longer press the pressure tube 18, and the pair of pressure rods 15 will approach each other under the pull of the first spring 16. After the pair of pressure rods 15 approach each other to a certain extent, they will be blocked by the limiting rod 6, so that the distance between the bottom of the pair of pressure rods 15 is greater than the distance between the top. As the limiting post 32 moves, the scraper 7 will scrape off the debris attached to the inner wall of the pressure tube 18, reducing the amount of debris remaining inside the pressure tube 18.
