Description

Technical Field

[0001] This invention relates to the field of hot melt extrusion technology for plastic products, and more specifically, to a device for the hot melt rough processing and recycling of plastic products. Background Technology

[0002] Hot melt extrusion is a molding process that continuously extrudes plastic raw materials through heating, plasticizing, and pressurizing. It is widely used in the production of plastic pipes, sheets, films, profiles, and other products. The core processes are heating and conveying, and it is common in existing technologies to operate these two processes simultaneously.

[0003] During this process, the hot melting phenomenon cannot guarantee the uniformity of the melt, which often causes blockage near the mold. At this time, the user needs to stop the machine and clean the blockage melt inside the extrusion box. However, there is still a large amount of melt and plastic granules to be conveyed inside the extrusion box, which leads to a lot of waste. Summary of the Invention

[0010] In a preferred embodiment, a second receiving box is fixedly mounted on the inner wall of the first extrusion box, and a fourth bevel gear and a fifth bevel gear are rotatably mounted on the inner wall of the second receiving box. The fourth bevel gear and the fifth bevel gear mesh with each other, and the fourth bevel gear is coaxially fixed on the surface of the first conveying rod.

[0011] In a preferred embodiment, a third receiving box is fixedly mounted on the inner wall of the second extrusion box, and a sixth bevel gear and a seventh bevel gear are rotatably mounted on the inner wall of the third receiving box. The sixth bevel gear and the seventh bevel gear mesh with each other, and the sixth bevel gear is coaxially fixed on the surface of the second conveying rod.

[0012] In a preferred embodiment, a transmission rod is coaxially fixed between the fifth and seventh bevel gears, the fourth and sixth bevel gears are arranged opposite each other, and the fifth and seventh bevel gears are arranged opposite each other.

[0013] In a preferred embodiment, the material box is equipped with a shearing mechanism, which includes a feeding funnel fixed to the top of the material box.

[0015] The present invention provides a plastic product hot melt rough processing and recycling equipment, the beneficial effects of which include: 1. By setting up a plastic extrusion recycling mechanism, when the melt inside the first extrusion box becomes blocked, the spline sleeve gradually moves, thereby causing the first conveying rod to drive the first conveying auger to rotate in the opposite direction, so that the melt inside the first extrusion box is transported in the opposite direction to the inside of the hopper. This avoids the problem of wasting the melt at the front of the first extrusion box after the user removes and cleans the first extrusion box when the mold position becomes blocked.

[0016] 2. By setting up an alternative extrusion mechanism, when the first conveying rod and the first conveying auger rotate in the initial state, the second conveying rod and the second conveying auger rotate in opposite directions. This prevents the plastic particles that have been sheared and crushed inside the hopper from entering the interior of the second extrusion chamber. Furthermore, because the first and second conveying augers rotate in opposite directions, the centrifugal force on the plastic particles inside the hopper is greater, making it easier for the plastic particles to enter the interior of the first extrusion chamber.

[0017] 3. By setting up a shearing mechanism, the user adds plastic granules into the inside of the feeding funnel, and at the same time, the first rotating rod and the second rotating rod rotate in opposite directions, thereby driving the first shearing plate and the second shearing plate to rotate in opposite directions, so that the plastic granules are crushed by centrifugal force. After the crushed plastic granules pass through the filter plate, they are heat-melted by the first conveying auger or the second conveying auger. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figures 1-9This invention provides a technical solution: a plastic product hot-melt rough processing and recycling device, including a workbench 1, a material box 2 on the top of the workbench 1, a plastic extrusion recycling mechanism on the material box 2, the plastic extrusion recycling mechanism including a first extrusion box 301 and a splined shaft 305, the first extrusion box 301 being disposed on the side wall of the material box 2, a first conveying rod 302 being rotatably disposed inside the first extrusion box 301, a first conveying auger 303 being disposed on the surface of the first conveying rod 302, a mold 304 being disposed on the side of the first extrusion box 301 away from the material box 2, the splined shaft 305 being coaxially fixed to the surface of the first conveying rod 302, a first receiving box 306 being fixed to the inner wall of the first extrusion box 301, and a rotatable part being disposed on the top of the inner wall of the first receiving box 306. A first bevel gear 307 is provided. A spline sleeve 308 is slidably fitted onto the surface of a spline shaft 305. A second bevel gear 309 and a third bevel gear 310 are coaxially fixed onto the surface of the spline sleeve 308. The second bevel gear 309 and the third bevel gear 310 are arranged opposite to each other. In the initial state, the third bevel gear 310 meshes with the first bevel gear 307. A first conveying rod 302 and a first conveying auger 303 penetrate into the inner cavity of the material box 2. The inner cavity of the first extrusion box 301 is connected to the inner cavity of the material box 2. The cross-section of the inner cavity of the first extrusion box 301 is circular. A first motor 311 is fixed to the top of the first extrusion box 301 by bolts and a mounting plate. The output end of the first motor 311 is fixedly connected to the first bevel gear 307 by a coupling. In the extrusion recycling mechanism, the user adds plastic granules into the feed hopper 2. After shearing, the first motor 311 is started. The rotation of the first bevel gear 307 causes the third bevel gear 310 to rotate, which in turn drives the spline shaft 305 to rotate via the spline sleeve 308. This causes the first conveying rod 302 to drive the first conveying auger 303 to rotate, allowing the crushed plastic granules to enter the interior of the first extrusion chamber 301. Heating wires are installed on the side wall of the first extrusion chamber 301, so that the plastic granules are melted into a molten substance while being conveyed by the first conveying auger 303. The molten substance is then formed into filaments and extruded at the die 304. When the molten substance inside the first extrusion chamber 301 becomes blocked... At this time, the spline sleeve 308 gradually moves until the teeth of the third bevel gear 310 and the first bevel gear 307 disengage, while the teeth of the second bevel gear 309 mesh with the teeth of the first bevel gear 307. This meshing of the second bevel gear 309 and the first bevel gear 307, due to their opposing arrangement, causes the second bevel gear 309 to drive the spline sleeve 308 to rotate in the opposite direction. This, in turn, causes the first conveying rod 302 to drive the first conveying auger 303 to rotate in the opposite direction, resulting in the melt inside the first extrusion box 301 being transported in the opposite direction to the inside of the material bin 2. This prevents the user from disassembling and cleaning the first extrusion box 301 when blockage occurs at the mold 304.To address the issue of wasted melt at the front of the first extrusion box 301, the user simply needs to continue rotating the first conveyor rod 302 after a blockage occurs. This will reverse the flow of melt that is not blocked, transporting it back to the material bin 2. Furthermore, if the blockage is not severe, the melt at the blocked location will also be transported in the reverse direction. When the first conveyor rod 302 and the first conveying auger 303 return to their initial rotation direction, the previously blocked melt is transported within the first extrusion box 301 while undergoing another heat-melting operation. Compared to existing technologies, this significantly reduces the costs incurred when blockage occurs at the mold 304. Reference Figures 1-9 A drive plate 312 is slidably disposed on the surface of the first conveying rod 302. A through groove 313 is formed on the drive plate 312, which is arc-shaped. A drive rod 314 is fixedly disposed on the side of the drive plate 312 near the spline sleeve 308. The drive rod 314 and the spline sleeve 308 are rotatably connected. Through the drive plate 312, the melt inside the first extrusion box 301, transported by the first conveying auger 303, passes over the drive plate 312 and is extruded through the mold 304. When the melt near the mold 304 becomes clogged, the accumulation of melt will squeeze the drive plate 312, causing the drive plate 312 to drive the drive rod 314 to move to the right. The drive rod 314 will drive the spline sleeve 308 to move to the right, thereby causing the teeth of the third bevel gear 310 to separate from the teeth of the first bevel gear 307, and the teeth of the second bevel gear 309 to mesh with the teeth of the first bevel gear 307, causing the first conveying rod 302 and the first conveying auger 303 to rotate in opposite directions. Reference Figures 1-9 A connecting box 315 is fixedly provided on the side of the first receiving box 306 near the drive plate 312. The drive rod 314 slides through the interior of the connecting box 315. A return plate 316 is fixedly provided on the surface of the drive rod 314. A spring 317 is provided between the return plate 316 and the inner wall of the connecting box 315. By providing the spring 317, when the melt that is blocked near the mold 304 is cleared, the spring force of the spring 317 causes the drive plate 312 and the spline sleeve 308 to return to their original positions. The meshing teeth of the second bevel gear 309 and the meshing teeth of the first bevel gear 307 separate, and the third bevel gear 310 and the first bevel gear 307 mesh again. Reference Figures 1-9The feed hopper 2 is equipped with a substitute extrusion mechanism, which includes a second extrusion box 401. The second extrusion box 401 is disposed on the side wall of the feed hopper 2, and its inner cavity is connected to the inner cavity of the feed hopper 2. The second extrusion box 401 and the first extrusion box 301 are arranged adjacent to each other. A second conveying rod 402 is rotatably disposed inside the second extrusion box 401. A second conveying auger 403 is disposed on the surface of the second conveying rod 402. The spiral direction of the second conveying auger 403 is consistent with the spiral direction of the first conveying auger 303. The second conveying rod 402 and the second conveying auger 403 are connected. The auger 403 extends into the inner cavity of the material box 2. By setting up an alternative extrusion mechanism, when the first conveying rod 302 and the first conveying auger 303 rotate in the initial state, the second conveying rod 402 and the second conveying auger 403 rotate in opposite directions. This prevents the plastic particles that have been sheared and crushed inside the material box 2 from entering the interior of the second extrusion box 401. Furthermore, since the first conveying auger 303 and the second conveying auger 403 rotate in opposite directions, the centrifugal force of the plastic particles inside the material box 2 is greater, making it easier for the plastic particles to enter the interior of the first extrusion box 301. Reference Figures 1-9A second receiving box 404 is fixedly mounted on the inner wall of the first extrusion box 301. A fourth bevel gear 405 and a fifth bevel gear 406 are rotatably mounted on the inner wall of the second receiving box 404. The fourth bevel gear 405 and the fifth bevel gear 406 mesh with each other. The fourth bevel gear 405 is coaxially fixed on the surface of the first conveying rod 302. A third receiving box 407 is fixedly mounted on the inner wall of the second extrusion box 401. A sixth bevel gear 408 and a seventh bevel gear 409 are rotatably mounted on the inner wall of the third receiving box 407. The sixth bevel gear 408 and the seventh bevel gear 409 mesh with each other. The sixth bevel gear 408 is coaxially fixed on the surface of the second conveying rod 402. A transmission rod 410 is coaxially fixed between the fifth bevel gear 406 and the seventh bevel gear 409. The fourth bevel gear 405 and the sixth bevel gear 408 are arranged opposite each other. By setting the second receiving box 404 and the third receiving box 407, when the first conveying rod 302 rotates, it drives the fourth bevel gear 405 to rotate. The rotation of bevel gear 405, through the meshing connection of the fourth bevel gear 405 and the fifth bevel gear 406, causes the fifth bevel gear 406 to drive the seventh bevel gear 409 to rotate via the transmission rod 410. Through the meshing connection of the seventh bevel gear 409 and the sixth bevel gear 408, the sixth bevel gear 408 drives the second conveying rod 402 to rotate in the opposite direction to the first conveying rod 302. This causes the second conveying auger 403 and the first conveying auger 303 to rotate in opposite directions. When the first conveying auger 303 conveys plastic granules, the plastic granules will not enter the interior of the second extrusion box 401. When the interior of the first extrusion box 301 is blocked, the first conveying auger 303 reverses, causing the second conveying auger 403 to reverse as well. This allows the plastic granules inside the hopper 2 to continue the extrusion operation through the second extrusion box 401. This means that when the interior of the first extrusion box 301 is blocked, there is no need to immediately stop the machine to clean the first extrusion box 301, thus improving production efficiency. Reference Figures 1-9The material box 2 is equipped with a shearing mechanism, which includes a feeding funnel 501 fixed to the top of the material box 2. A bearing plate 502 is fixed to the top of the feeding funnel 501, and a protective shell 503 is fixed to the bottom of the bearing plate 502. A first rotating rod 504 and a second rotating rod 505 are rotatably arranged inside the protective shell 503. The first rotating rod 504 and the second rotating rod 505 are coaxially arranged. The first rotating rod 504 is sleeved on the surface of the second rotating rod 505. A bearing rod 506 is fixed to the surface of the first rotating rod 504, and a first shearing plate 5 is fixed on the bearing rod 506. 07. A second shearing plate 508 is fixed on the surface of the second rotating rod 505, and a filter plate 509 is provided on the inner wall of the material box 2. By setting a shearing mechanism, the user adds plastic granules into the inside of the feeding funnel 501, and at the same time, the first rotating rod 504 and the second rotating rod 505 rotate in opposite directions, thereby driving the first shearing plate 507 and the second shearing plate 508 to rotate in opposite directions, so that the plastic granules are crushed by centrifugal force. After the crushed plastic granules pass through the filter plate 509, they are heat-melted by the first conveying auger 303 or the second conveying auger 403. Reference Figures 1-9 An eighth bevel gear 510 is rotatably mounted inside the side wall of the protective shell 503. A ninth bevel gear 511 is coaxially fixed to the surface of the first rotating rod 504, and a tenth bevel gear 512 is coaxially fixed to the surface of the second rotating rod 505. Both the ninth and tenth bevel gears 511 and 512 mesh with the eighth bevel gear 510. The ninth and tenth bevel gears 511 and 512 are arranged opposite to each other. A second motor 513 is fixed to the top of the bearing plate 502 by bolts and a mounting plate. The output end of the second motor 513 is fixed to the second rotating rod 505 via a coupling. A fixed connection is established. By setting a second motor 513, the second motor 513 is started, driving the second rotating rod 505 to rotate. The second rotating rod 505 drives the tenth bevel gear 512 to rotate simultaneously. Through the meshing connection between the tenth bevel gear 512 and the eighth bevel gear 510, the eighth bevel gear 510 is rotated. Through the meshing connection between the eighth bevel gear 510 and the ninth bevel gear 511, and the relative arrangement of the ninth bevel gear 511 and the tenth bevel gear 512, the first rotating rod 504 and the second rotating rod 505 rotate in opposite directions.

[0023] Specifically, the working process or principle of this plastic product hot melt rough processing and recycling equipment is as follows: During use, the user adds plastic granules into the feeding funnel 501, starts the second motor 513, which drives the second rotating rod 505 to rotate. The second rotating rod 505 drives the tenth bevel gear 512 to rotate simultaneously. Through the meshing connection between the tenth bevel gear 512 and the eighth bevel gear 510, the eighth bevel gear 510 rotates. Through the meshing connection between the eighth bevel gear 510 and the ninth bevel gear 511, and the relative arrangement of the ninth bevel gear 511 and the tenth bevel gear 512, the first rotating rod 504 and the second rotating rod 505 rotate in opposite directions, thereby driving the first shearing plate 507 and the second shearing plate 508 to rotate in opposite directions. The rotation proceeds in the opposite direction, causing the plastic granules to be broken down by centrifugal force. After passing through the filter plate 509, the first motor 311 is activated. The rotation of the first bevel gear 307 causes the third bevel gear 310 to rotate, which in turn drives the spline shaft 305 to rotate via the spline sleeve 308. This causes the first conveying rod 302 to drive the first conveying auger 303 to rotate, allowing the broken plastic granules to enter the interior of the first extrusion box 301. Heating wires are installed on the side wall of the first extrusion box 301, so that the plastic granules are melted into a molten substance while being conveyed by the first conveying auger 303. The molten substance inside the first extrusion box 301 is transported by the first conveying auger 303, passing over the drive plate 312 and... The extrusion process is performed through mold 304, forming filaments at the mold 304 and extruding them. When the first conveying rod 302 rotates, it drives the fourth bevel gear 405 to rotate. Through the meshing connection between the fourth bevel gear 405 and the fifth bevel gear 406, the fifth bevel gear 406 drives the seventh bevel gear 409 to rotate via the transmission rod 410. Through the meshing connection between the seventh bevel gear 409 and the sixth bevel gear 408, the sixth bevel gear 408 drives the second conveying rod 402 to rotate in the opposite direction to the first conveying rod 302. This causes the second conveying auger 403 and the first conveying auger 303 to rotate in opposite directions. When the first conveying auger 303 conveys the plastic granules, the plastic granules will not enter the second extrusion box 40. Inside 1, when the melt inside the first extrusion box 301 becomes clogged, especially near the mold 304, the accumulated melt will compress the drive plate 312, causing it to move the drive rod 314 to the right. The drive rod 314 then moves the spline sleeve 308 to the right, causing the teeth of the third bevel gear 310 to separate from the teeth of the first bevel gear 307, while the teeth of the second bevel gear 309 mesh with those of the first bevel gear 307. This causes the first conveying rod 302 and the first conveying auger 303 to rotate in opposite directions, resulting in the melt inside the first extrusion box 301 being transported in the opposite direction to the inside of the material box 2. The reversal of the first conveying auger 303 causes the second conveying auger 403 to reverse as well.This allows the plastic granules inside the feed hopper 2 to continue the extrusion process through the second extrusion chamber 401.
