Description

Technical Field

[0001] The invention relates to the technical field of plastic material processing and molding, in particular to a multifunctional calendering molding device for a thermally conductive pad. Background Art

[0002] The main materials of silicone thermal pads include raw rubber, compounding agents, fiber materials and metal materials. Raw rubber is the basic material, and compounding agents are auxiliary materials added to improve certain properties of rubber products. Some even add fiber materials and metal materials as the skeleton materials of rubber products to enhance mechanical strength and limit product deformation. In the process of raw material preparation, the ingredients must be accurately weighed according to the formula, and the raw rubber and compounding agents must be processed, such as baking, cutting, crushing, screening, heating, melting, filtering impurities, etc., to ensure that they can be evenly mixed with each other. Once the mixed materials are ready, the next step is to shape them. The molding methods usually include pressing and extrusion. During the pressing process, the high-temperature material in the molten state is transported to the table of the calendering equipment through a pipeline. There are calendering rollers and material guide plates on the table to prevent the material from flowing to both sides. The material flows to the bottom of the calendering rollers and is formed after pressing. The upper and lower sides of the material are covered with plastic film or PEF release film to prevent the thermal conductive silicone sheet from being damaged or contaminated during processing or transportation. After cooling, cutting and other processing, the silicone thermal conductive gasket is obtained.

[0003] The silicone thermal pad for low-temperature application begins to soften above 80°C, and the material in the molten state of the silicone thermal pad is 100°C to ensure its fluidity. The material falling on the table is 100°C, which has greater fluidity and adhesion. Some materials are easy to adhere to the surface of the calendering roller when passing through the calendering roller, and rotate with the calendering roller, affecting the subsequent pressing of the material. The current solution to this problem is to set a scraper on the surface of the calendering roller. The length of the scraper is roughly the same as the length of the calendering roller. The two fit each other. The material will be cleaned up by the scraper in the process of rotating with the calendering roller, which will not affect the subsequent pressing work; however, the scraper has been attached to the surface of the calendering roller, which is worn, and the calendering roller has been in contact with the fluid high-temperature material. After the calendering roller absorbs heat for a long time, it collides and contacts with the scraper more closely, which will aggravate the wear of the two and shorten the service life. At the same time, it also affects the pressing work and causes excessive extrusion of the material; and the material removed by the scraper has long been cooled and solidified after being recycled, and cannot be directly put back into the equipment for pressing processing, which causes waste. Summary of the invention

[0004] The purpose of the present invention is to provide a multifunctional calendering forming device for thermally conductive gaskets, which can allow a scraper to perform cleaning work only when there is material adhering to the surface of the calendering roller, thereby preventing the scraper from being in contact with the calendering roller all the time and causing wear.

[0050] The detection and control mechanism 6 includes a first cylinder 61, a second cylinder 62, a support plate 613 and an installation long plate 614. The support plate 613 and the installation long plate 614 are both bolted to the frame 3. The first cylinder 61 is bolted to the top of the support plate 613, and the second cylinder 62 is bolted to the bottom of the installation long plate 614. A first piston 63 is slidably arranged on the inner wall of the first cylinder 61, and a second piston 66 is slidably arranged on the inner wall of the second cylinder 62. A first piston rod 64 is bolted to the other side of the first piston 63, and the other end of the first piston rod 64 extends to the outside of the first cylinder 61 and is bolted to a connecting block 65, and the connecting block 65 is bolted to the scraper block 4.

Sealing kits are provided at the inlet and outlet of the first cylinder 61 and the second cylinder 62 to ensure sealing when the connecting rod piston rod enters and exits the cylinder. A pressure block 611 is bolted to the top of the connecting plate 610, and a rotating cylinder 612 is rotatably connected to the bottom of the connecting plate 610. A first through pipe 68 and a second through pipe 69 are respectively connected on both sides of the surface of the first cylinder 61, and the other ends of the first through pipe 68 and the second through pipe 69 are connected to the second cylinder 62. Before working, the first cylinder 61, the second cylinder 62, the first through pipe 68 and the second through pipe 69 are filled with hydraulic oil.

[0051] During the calendering process of the thermal conductive gasket, the material in the molten state enters the surface of the feed table 1 under the conveyance of the material pump, and flows along the surface of the feed table 1 to the calendering roller body 2. When the calendering roller body 2 is working, it is driven by the motor on the equipment, and the calendering roller body 2 rotates to squeeze and transport the material in the molten state. Then, the upper and lower surfaces of the material are pasted with plastic films under the action of other rollers to prevent the calendered thermal conductive silicone sheet from being damaged or contaminated during processing or transportation. During the rotation of the calendering roller body 2, the gravity of the pressing block 611 Under the action of the rotating drum 612, the rotating drum 612 contacts the surface of the calendering roller body 2, and the rotating drum 612 can rotate without generating severe friction with the surface of the calendering roller body 2. At the same time, the scraper block 4 does not contact the surface of the calendering roller body 2, and a small gap is left in the middle; when there is material adhering to the surface of the calendering roller body 2, the calendering roller body 2 will drive it to follow the rotation movement. When the rotating drum 612 contacts the protruding material, the rotating drum 612 will be lifted up a short distance, and the rotating drum 612 drives the connecting plate 610 to move toward the direction of the second cylinder 62, so that the second piston rod 67 moves toward the second cylinder 6 2 contracts slightly, and the second piston 66 pushes the upper part of the hydraulic oil into the second through-tube 69. Under the action of oil transmission, part of the hydraulic oil in the second through-tube 69 enters the first cylinder 61 on the side away from the connecting block 65, and then pushes the first piston 63 to move. The first piston 63 pushes the hydraulic oil on the other side of the first cylinder 61 and the first piston rod 64 to move, so that part of the hydraulic oil enters the first through-tube 68 and flows to the second cylinder 62, so that the connecting block 65 and the scraper block 4 are close to the rolling roller body 2, and the scraper block 4 is attached to the surface of the rolling roller body 2 and at the tip 5 With the cooperation of the rotary drum 612, the materials adhered to the surface of the rolling roller body 2 are scraped off, and only when the rotary drum 612 contacts the materials, the scraper block 4 can be attached to the surface of the rolling roller body 2 under the action of the oil transmission to perform cleaning work. The scraper block 4 itself does not need to be in contact with the rolling roller body 2 all the time, which reduces wear. After the rotary drum 612 does not contact the raised materials, that is, after the surface of the rolling roller body 2 is cleaned, the rotary drum 612 contacts the surface of the rolling roller body 2 again under the action of gravity, and uses the reverse oil transmission to make the scraper block 4 leave the surface of the rolling roller body 2 again, leaving a gap.

[0052] During the processing, the fan 18 can be turned on to generate negative pressure at the entrance, which allows external air to enter from the feed trough 7, and generates suction near the feed trough 7. The scraped material temporarily stays at the blade tip 5, cools down due to the flow of air, and gradually solidifies. Under the action of suction, it is adsorbed into the feed trough 7, and the scraped material enters the processing box 12 through the connecting pipe 8, the hose 9, the connecting pipe 10 and the cross pipe 11. Since the air in the processing box 12 flows upward, the material is intercepted by the blocking net 15, and the scraped material remains inside the processing box 12. As the fan 18 continues to be turned on, the upward airflow keeps the material on the surface of the blocking net 15; then the air flows through the upper outlet 13, the ventilation pipe 16 and the arc pipe 17 into the fan 18, and is discharged from the outlet of the fan 18 into the inside of the box 19.

Under the action of the reaction force of the first spring 249, the first blocking plate 248 is subjected to a force in the direction away from the first transverse groove 247, so that the first roller 2411 is fitted on the surface of the protruding disk 245. Similarly, under the action of the second spring 2414, the second roller 2416 is fitted on the surface of the recessed disk 246. Since the disk diameter of the recessed disk 246 is larger than the disk diameter of the protruding disk 245, the first blocking plate 248 is not completely inside the first transverse groove 247 at this time, so that the upper outlet 13 is in an open state, and the air sucked in by the fan 18 flows normally. The second blocking plate 2413 is mostly located in the second transverse groove 2412, so that the lower outlet 14 is in a closed state.When the vertical column 244 drives the protruding plate 245 and the recessed plate 246 to rotate synchronously, when the first roller 2411 contacts the convex part of the surface of the protruding plate 245, the second roller 2416 below contacts the concave part of the surface of the recessed plate 246, which makes the first roller 2411, the first movable rod 2410 and the first blocking plate 248 move toward the inside of the first transverse groove 247 to temporarily block the upper outlet 13, while the second roller 2416, the second movable rod 2410 and the first blocking plate 248 below are moved to the inside of the first transverse groove 247. 5. The second blocking plate 2413 moves in a direction away from the second transverse groove 2412, so that the lower outlet 14 is temporarily in an open state. Since the upper outlet 13 is temporarily closed, the air flow is temporarily cut off, which makes the material on the surface of the blocking net 15 fall downward and enter the interior of the inclined cylinder 254 from the lower outlet 14 and the feed pipe 251. When the first roller 2411 leaves the raised part of the surface of the protruding plate 245, the first blocking plate 248 is reset to open the upper outlet 13. The air flows again, allowing the subsequently shoveled materials to continue to enter the processing box 12, and the first roller 2411 below leaves the recessed part of the recessed plate 246, allowing the second blocking plate 2413 to block the lower outlet 14 again to prevent the materials entering the inclined cylinder 254 from being sucked back, so that the shoveled materials remain in the inclined cylinder 254, and most of the time, the upper outlet 13 is open and the lower outlet 14 is closed, and the air continues to flow to suck in the shoveled materials, and in a short period of time, the upper outlet 13 is closed. The outlet 13 is closed, the lower outlet 14 is opened, the air flow is temporarily cut off, and the material falls into the inclined cylinder 254; the upper and lower sides of the fixed frame 242 are bolted with fixed rods 2417, and the other end of the fixed rod 2417 is bolted with a sliding sleeve 2418, and the first movable rod 2410 and the second movable rod 2415 are respectively slidably connected with the inner walls of the sliding sleeves 2418 on the upper and lower sides, and the first movable rod 2410 and the second movable rod 2415 can slide along the inner wall of the sliding sleeve 2418 to increase the stability of the movement.

One end of the second delivery pipe 264 is connected to the outlet of the supply pump 263, and the other end of the second delivery pipe 264 is connected to the through cavity 255. The other side of the surface of the storage box 261 is also connected to a return pipe 265, and the other end of the return pipe 265 is connected to the through cavity 255. The interior of the storage box 261 is filled with heat transfer oil. The heating mechanism 26 also includes a first delivery pipe 262 and a second delivery pipe 264. The frame 266 inside the body 19 has a heating refrigerator 267 fixed on the inner side of the frame 266. The heating refrigerator 267 is a Peltier TEC1-12708 high-power semiconductor refrigeration plate, which can withstand a high temperature of 150°C, a heating temperature of 150°C, and a cooling temperature of minus 40°C. The heating surface of the heating refrigerator 267 faces upward, and the cooling surface of the heating refrigerator 267 faces downward. A plurality of first copper plates 268 are bolted to the top of the frame 266, and the first copper plates 268 penetrate into the interior of the storage box 261. A plurality of first through holes 269 are formed on the surface of the first copper plates 268. When the heating refrigerator 267 and the supply pump 263 are turned on, the heating surface of the heating refrigerator 267 is heated. The temperature generated is about 130℃, and the temperature generated by the refrigeration surface is about minus 20℃. The first copper plate 268 transfers heat to the inside of the storage box 261, so that the heat-conducting oil inside the storage box 261 is heated to about 120℃. The supply pump 263 is turned on, so that the heat-conducting oil inside the storage box 261 passes through the first delivery pipe 262, the supply pump 263, and the second delivery pipe 264 into the through cavity 255. The high-temperature heat-conducting oil transfers heat to heat the material entering the inclined cylinder 254, so that the temperature of the material exceeds 100℃ (the equipment mainly produces silicone thermal pads, and silicone thermal pads for low-temperature applications. The silicone thermal pads for low-temperature applications are 8 The material recovered in the inclined cylinder 254 gradually melts, and after a long period of operation, a certain amount of material is accumulated, such as one hour. At this time, the material inside the inclined cylinder 254 is completely melted and in a molten state. The drive motor 253 is turned on, and the drive motor 253 drives the auger blade 257 to rotate, so as to transport the molten recycled material and discharge it to the feed table 1 through the discharge pipe 258, so as to realize the recycling of the material and reduce the waste of materials. The heat transfer oil after heat release returns to the interior of the storage box 261 through the return pipe, and passes through the first through hole 269 to obtain the heat from the first copper plate 268.

The number of second through holes 272 is several and they penetrate the surface of the second copper plate 271. The cooling surface of the heating refrigerator 267 transfers the cold energy to the second copper plate 271. The wind discharged from the fan 18 enters the lower part of the box body 19 and passes through the second through hole 272 to absorb the cold energy from the second copper plate 271 to generate cold wind. The cold wind passes through the exhaust hood 20, the air supply pipe 21, the connecting pipe 22 and the air outlet hood 23 and then blows to the surface of the rolling roller body 2 to prevent the rolling roller body 2 from absorbing heat for a long time and expanding, causing excessive extrusion. At the same time, the rolling roller body 2 absorbs heat while being cooled by wind, which can also prevent the continuous wind cooling from causing a large contraction of itself. The cold wind can also blow to the surface of the rotating drum 612 and the scraper block 4 to prevent these two components from overheating and expanding.
