Description

Technical Field

[0001] The invention relates to the technical field of MPPO preparation, and in particular to a system for preparing a flame-retardant MPPO composite material. Background Art

[0002] In the prior art, the MPPO composite material is mixed and hot-pressed, and the extruded soft material is stretched into a long strip and immersed and cooled. A small amount of toxic gases such as organic hydrocarbons will be released during the process of the material being discharged and contacting the air and cold water. The traditional method is to use ventilation and filtration equipment to absorb the slightly toxic gas in the working area as a whole, and then discharge it after filtering through the filter cartridge. However, due to the large temperature difference between the air and cooling water and the material after hot pressing, the concentration of harmful substances released from the material at the discharge port is easy to increase. Even if the workers wear basic safety measures such as protective masks, long-term work will endanger the health of the workers, and the filter element of the filter cartridge needs to be replaced frequently, resulting in increased costs.

[0003] In addition, the heated material will become soft and sticky, and usually needs to avoid contact with the inner wall of the cooling pool to avoid adhesion of impurities and affect the quality. Generally, after the material enters the cooling pool, it needs to pass through a rotating roller as a limiter. On the one hand, the stretched long strip material can be evenly immersed in the cooling pool, and on the other hand, the rotating roller can also assist in discharging the material. However, at present, when the material just comes out of the extrusion equipment, the material is exposed to the air, and usually people need to approach the discharge port to manually pull and thread the material. During the operation, workers can easily inhale and disturb the emitted toxic gases, which affects the normal removal of the toxic gases by the equipment and is not conducive to the purification of the working environment.

[0004] In view of this, the present invention proposes a flame retardant MPPO composite material preparation system to make up for and improve the deficiencies of the prior art. Summary of the invention

[0014] Preferably, the outlet direction of the exhaust scoop is vertically arranged relative to the hot press, and the position of the exhaust scoop corresponds to the discharge port at the bottom of the hot press.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Through the setting of the temperature transition mechanism, the protective cover is used to isolate the closed area, and then the hot air is introduced through the L-shaped tube. Since the outlet direction of the exhaust scoop on the L-shaped tube is set vertically relative to the hot press, the material at the outlet can be blown horizontally, and the material falls vertically downward, so the material can be cooled quickly without hindering the continuous output of the material, thereby reducing the time for the material to produce toxic gas and reducing the toxic gas content. In addition, the cooling water in the heating pool makes the air and water that the material contacts for the first time after being squeezed out of the hot press have a higher temperature than the room temperature, and then the normal water temperature is cooled. In this way, the temperature of the material is gradually reduced, which can reduce the decomposition of the material and the release of harmful gases caused by the rapid temperature change, thereby increasing the safety of the workers and reducing the frequent replacement of the filter cartridge, resulting in increased costs. In addition, slow cooling can help the material solidify more evenly, reduce internal stress, and improve the quality of the product.

[0017] 2. Through the setting of the right-angle frame and the right-angle scraper, the visual window can be completely scraped clean at one time, reducing the time of visual obstruction during workers' observation, which is conducive to workers' real-time observation of the discharge situation. In addition, the material drives the rubber roller to rotate, and the sleeve column is driven to rotate synchronously, so that the right-angle scraper can reciprocate to scrape off the fog or water vapor on the visual window without adding a driving source, reducing energy waste;

[0018] 3. Through the setting of the initial pulling mechanism, whenever the equipment is shut down and restarted, the worker can turn the hand wheel outside the protective cover to make the plastic rod automatically rotate a circle, wrap around the head of the material, and evenly and equidistantly pass a row of extruded materials through the nearest rubber roller. The semi-automatic implementation method avoids the worker's body being directly exposed to the toxic gas at the discharge port during manual operation in the prior art, effectively preventing the inhalation of toxic gases emitted by the material and the disturbance of the gas, which affects the normal absorption of toxic gases by the equipment. In addition, the plastic rod can pull out the material evenly and equidistantly, corresponding to the annular groove on the rubber shaft, which is convenient for sliding fit, and there is no need to adjust the material separately to avoid the situation where the material is of different thicknesses;

[0019] 4. Through the setting of the clamping plate and the counterweight block, the top of the clamping plate is designed to be an arc surface, and the two clamping plates form a circular slot, which is evenly arranged in the arc groove of the clamping plate with anti-slip pads, which can effectively increase the friction, stably clamp the plastic rod, and prevent the plastic rod from falling off during rotation. The counterweight block is located at the bottom of the flip plate, which can keep the clamped plastic rod always at the top and not be deflected by the water flow resistance, so that the plastic rod can maintain a sufficient rotation range when winding around the material, thereby improving the winding effect.

[0033] Embodiments of the present invention

[0034] Please refer to Figures 1 to 8 As shown:

[0035] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a flame-retardant MPPO composite material preparation system, including a raw material mixing module, a hot pressing molding module, a cooling and cutting module and a finished product detection module, wherein the cooling module includes a melting box 1, and a hot press 2 is fixedly installed on the top of the melting box 1. A flame-retardant MPPO composite material preparation system includes: a temperature transition mechanism 5 and an initial material pulling mechanism 6, the temperature transition mechanism 5 is located in the middle of the hot press 2, and the initial material pulling mechanism 6 is located at the bottom of the melting box 1;

[0036] The temperature transition mechanism 5 is used to slow down the cooling temperature of the composite material;

[0037] The initial material drawing mechanism 6 is used to quickly and evenly draw out the extruded composite material;

[0038] The temperature transition mechanism 5 includes a protective cover 52 fixedly installed at the bottom of the hot autoclave 2, a visual window 53 fixedly connected to the middle of the protective cover 52, an exhaust pipe 51 fixedly connected to the top of the protective cover 52, an air collecting cover 54 fixedly connected to the outer wall of the melting box 1, an L-shaped pipe 55 fixedly connected to the side of the air collecting cover 54 close to the protective cover 52, a side of the L-shaped pipe 55 away from the air collecting cover 54 fixedly penetrates the protective cover 52 and extends to the bottom of the hot autoclave 2, and a plurality of exhaust scoops 514 are fixedly connected to the side of the L-shaped pipe 55 close to the hot autoclave 2 at equal intervals;

[0039] The temperature transition mechanism 5 also includes a rotating rod 58 rotatably connected to the corner of the protective cover 52, a sleeve column 59 is fixedly connected to the middle of the rotating rod 58, a right-angle frame 510 is slidably connected to the outer wall of the sleeve column 59, a right-angle scraper 511 is fixedly connected to the outer wall of the right-angle frame 510, the outer wall of the right-angle scraper 511 is slidably connected to the inner wall of the visual window 53, a protrusion 513 is fixedly connected to the inner wall of the right-angle frame 510, a corrugated groove 512 matching the size of the protrusion 513 is opened on the outer wall of the sleeve column 59, the protrusion 513 is slidably connected in the corrugated groove 512, the rotating rod 58 rotates on the side close to the L-shaped tube 55 to penetrate the outer wall of the protective cover 52, a pulley 57 is fixedly connected to the outer wall of the edge of the rotating rod 58, and a frosted belt 56 is frictionally connected to the outer wall of the pulley 57;

[0040] The outlet direction of the exhaust scoop 514 is vertically arranged relative to the hot autoclave 2, and the position of the exhaust scoop 514 corresponds to the discharge port at the bottom of the hot autoclave 2;

[0041] Among them: the protective cover 52 extends from the bottom of one side of the autoclave 2 to an underwater position in the water pool 61. Because toxic gases such as organic hydrocarbons are not easily soluble in water, the protective cover 52 is equivalent to sealing the toxic gases in the discharge port area of ​​the autoclave 2 inside the protective cover 52. One end of the rubber roller 4 located inside the water pool 61 rotates through the water pool 61 and is fixedly connected to another pulley 57. The other pulley 57 is also frictionally connected to the inner surface of the frosted belt 56. The sleeve column 59 is used to drive the right-angle frame 510 to slide back and forth on the inner wall of the visual window 53 for defogger.

[0042] The effects achieved by this embodiment are as follows: in the prior art, the temperature difference between the air and cooling water and the temperature of the material after hot pressing is too large, so the concentration of harmful substances released from the material at the discharge port is easy to increase. Even if the workers wear basic safety measures such as protective masks, long-term work will endanger the health of the workers, and the filter element of the filter cartridge needs to be replaced frequently, resulting in increased costs. Compared with the prior art, through the implementation of this embodiment, the temperature transition mechanism 5 is set to cover the discharge area with a protective cover 52, accurately absorb toxic gases and prevent diffusion, and the hot air generated by the melting box 1 can be transported to the position of the discharge port of the hot press 2 and blown into the protective cover 52, and the heater 515 heats the cooling water in the water pool 61, so that after the material is squeezed out, the air and cooling water it contacts have a certain temperature, rather than directly at room temperature, to avoid the material emitting high concentrations of toxic gases due to a sudden drop in temperature, thereby ensuring the safety of the working environment.

[0043] For further examples, please refer to Figure 1 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown:

[0044] The initial material pulling mechanism 6 includes a pool 61 fixedly connected to the bottom of the melting box 1, and both sides of the inner surface of the bottom of the pool 61 are fixedly connected with fixed plates 66, and the middle parts of the two fixed plates 66 are rotatably connected with threaded rods 64, and the sides of the two threaded rods 64 away from the fixed plates 66 are rotatably connected to the outer wall of the pool 61, and the outer walls of the threaded rods 64 are threadedly connected with sliders 63, and the tops of the two sliders 63 are rotatably connected with rotating shafts 616, and the ends of the two rotating shafts 616 away from each other are fixedly connected with flat gears 67, and the ends of the rotating shafts 616 close to each other are fixedly connected with flip plates 610, and the bottoms of the two flip plates 610 are fixedly connected with counterweights 69, and both sides of the flip plates 610 are slidably connected with a pair of clamps 68, and the bottoms of the two clamps 68 are fixedly connected with reset springs 617, and the tops of the clamps 68 are fixedly connected with a plurality of anti-skid pads 618, and the outer walls of the anti-skid pads 618 are clamped with plastic rods 3;

[0045] The initial pulling mechanism 6 also includes a long strip 65 fixedly connected to both sides of the bottom of the pool 61, and a plurality of teeth 611 are fixedly connected to the side of the two long strips 65 away from the fixed plate 66, and the size of the teeth 611 is adapted to the flat gear 67. A pair of mounting plates 612 are fixedly connected to the outer wall of the pool 61, and a rotating rod 613 is rotatably connected to the middle of the mounting plate 612. Main bevel gears 615 are fixedly connected to both sides of the outer wall of the rotating rod 613, and the outer walls of the two main bevel gears 615 are meshed with auxiliary bevel gears 614. The two auxiliary bevel gears 614 are fixedly connected to the threaded rod 64 on the side away from the rotating rod 613, and the edge of the rotating rod 613 is fixedly connected to the hand wheel 62. A heater 515 is fixedly installed at the bottom of the pool 61, and the inner wall and the top of the pool 61 are rotatably connected to the rubber roller 4.

[0046] The top and middle of the clamping plate 68 are respectively provided with arc grooves adapted to the plastic rod 3 and the rotating shaft 616, and the anti-slip pads 618 are evenly arranged along the arc grooves on the top of the clamping plate 68;

[0047] Among them: when the flat gear 67 moves to the tooth 611 area, the flat gear 67 can rotate one circle, the plastic rod 3 is used to wrap the material just out of the hot press 2, so as to facilitate the synchronous stretching of the materials from multiple outlets, and the outer wall of the rubber roller 4 is equidistantly provided with multiple annular grooves adapted to the material, and the tooth 611 is arranged below the outlet of the hot press 2.

[0048] The effects achieved by this embodiment are as follows: In the prior art, when the material just comes out of the extrusion equipment, the material is exposed to the air, and it is usually necessary to manually approach the discharge port to manually pull and thread the material. During the operation, the worker can easily inhale and disturb the emitted toxic gas, which affects the normal absorption of the toxic gas by the equipment and is not conducive to the purification of the working environment. Compared with the prior art, through the implementation of this embodiment, the initial pulling mechanism 6 can enable the worker to turn the hand wheel 62 outside the protective cover 52, so that the plastic rod 3 automatically rotates one circle, wraps around the head of the material, and evenly and equidistantly passes a row of extruded materials through the nearest rubber roller 4. The semi-automatic implementation method avoids the worker's body being directly exposed to the toxic gas at the discharge port during manual operation in the prior art, and effectively prevents the inhalation of toxic gas emitted by the material and the disturbance of the gas, which affects the normal absorption of toxic gas by the equipment.

[0049] The complete usage steps and working principle of the above embodiment are as follows:

[0050] In the initial state: the return spring 617 is in a naturally relaxed state, the two clamping plates 68 are close to each other, the slider 63 is close to the fixed plate 66, and the flat gear 67 and the teeth 611 are separated from each other.

[0051] Working process: When in use, the MPPO composite material is squeezed from a row of outlets of the hot press 2 and falls freely in a soft and viscous state. The movement trajectory is that it first contacts the air, then immerses in the cooling water of the water pool 61, and then the worker manually passes the material through the rubber roller 4 underwater. The material is continuously stretched by the worker to be parallel to the bottom of the water pool 61, and then emerges from the water surface after a bend of the rubber roller 4, and can enter the next cooling pool. When continuously discharging, the hot air emitted from the exhaust of the melting box 1 can be discharged into the L-shaped tube 55 through the air collecting hood 54, and is evenly discharged through the exhaust scoop 514 of the L-shaped tube 55. Since the outlet direction of the exhaust scoop 514 is vertically arranged relative to the hot press 2, and its position corresponds to the bottom outlet of the hot press 2, the hot air discharged from the exhaust scoop 514 will blow horizontally on a row of materials at the outlet for initial cooling, and the hot air continuously enters the protective cover 52, so that the temperature inside the protective cover 52 will also be higher than the external room temperature, which can ensure that the material is first contacted The air temperature will not be too low, and there is a certain constant temperature effect. Then, the cooling water in the water pool 61 is heated by the heater 515, and the temperature can be adjusted according to the actual situation, so that the material enters the water for a second cooling, and the heated water can also enter the protective cover 52 for insulation due to the rising heat. The combination of the two can make the material have a temperature transition in the water pool 61, which can greatly reduce the generation of toxic gases. When the material then enters the normal temperature cooling water, basically no toxic gases will be generated, which increases the safety of the working environment. By setting the protective cover 52 away from the bottom of one side of the autoclave 2 and extending to the underwater position in the water pool 61, because toxic gases such as organic hydrocarbons are not easily soluble in water, the protective cover 52 is equivalent to sealing the toxic gases in the discharge port area of ​​the autoclave 2 inside the protective cover 52, so that the toxic gases with the highest concentration generated at the moment of contact between the material and the water are basically gathered inside the protective cover 52, which is convenient for being discharged by the exhaust pipe 51, and the remaining trace gases are discharged through the external ventilation system;

[0052] Furthermore, during operation, the temperature difference between the inside and outside of the protective cover 52 may cause fog to form on the visual window 53. As the material is continuously discharged, it will be pulled by the rear driving device to slide on the rubber roller 4, causing the rubber roller 4 to roll continuously. Therefore, the rubber roller 4 is used to drive the bottom pulley 57 to rotate, and then the frosted belt 56 is rotated, thereby driving the top pulley 57 to rotate. Since the top pulley 57 is fixedly connected to the rotating rod 58, the rotating rod 58 and the sleeve column 59 rotate synchronously therewith. The projection 513 slides in the corrugated groove 512 on the sleeve column 59. The corrugated groove 512 is in a corrugated shape around the sleeve column 59. Therefore, when the sleeve column 59 rotates, the projection 513 can drive the right-angle frame 510 to slide back and forth on the sleeve column 59, and then drive the right-angle scraper 511 to reciprocate synchronously through the right-angle frame 510, that is, the right-angle scraper 511 slides back and forth on the inner surface of the visual window 53 to scrape off fog or water vapor, keep the visual window 53 clear and visible, which is conducive to workers observing the state of the material;

[0053] Please refer to the above working process Figures 1 to 5 .

[0054] Furthermore, whenever the equipment is shut down and restarted, the material needs to be re-passed through the rubber rollers 4 in multiple cooling pools. First, the plastic rod 3 is clamped in the clamp plate 68. Through the concave arc design on the top of the clamp plate 68, the two clamp plates 68 form an arc groove, and the anti-skid pads 618 are equidistantly arranged in the arc groove, which can effectively increase the friction. With the elastic stretching of the reset spring 617, the plastic rod 3 can be stably fixed in the position above the flip plate 610. Then the worker turns the hand wheel 62 to drive the rotating rod 613 and the main bevel gear 615 to rotate together, and then the main bevel gear 615 drives the secondary bevel gear 614 and the threaded rod 64 to rotate together, and then the threaded rod 64 is rotated to move the slider 63 from the initial position toward the direction of the hand wheel 62. Through the gravity of the counterweight block 69, the water resistance is resisted, so that the plastic rod 3 basically maintains its position underwater, and the manual rotation of the hand wheel 62 prevents the plastic rod 3 from moving too fast, so the plastic rod 3 basically does not deform until the flat gear 67 reaches the gear When the tooth 611 reaches the position, the flat gear 67 rotates one circle through the meshing of the tooth 611, and the turning plate 610, the clamping plate 68 and the anti-skid pad 618 rotate one circle together through the rotating shaft 616, and this position is maintained to wait for the material to be discharged. Since the tooth 611 is set at the lower position of the outlet of the hot press 2, when the employee observes the material falling into the water through the visual window 53, the worker reversely rotates the hand wheel 62. Similarly to the above, the flat gear 67 on the tooth 611 can make the plastic rod 3 rotate one circle, and the soft material head is wrapped around the surface of the plastic rod 3. The hand wheel 62 is continued to be rotated in the opposite direction. The plastic rod 3 can evenly and equidistantly pass a row of materials through the nearest rubber roller 4, and then the worker can use tools or wear gloves to continue to stretch the plastic rod 3 that has been wrapped with the material forward, and enter the following process. The material can be quickly and easily pulled out evenly. The plastic rod 3 can be recycled as a raw material after use, and the worker performs the operation of stretching the material outside the protective cover 52, which is highly safe and prevents the toxic gas emitted by the material from being inhaled and disturbed;
