Description

Technical Field

[0001] This invention relates to the technical field of recycled plastic extrusion, and more particularly to a semi-automatic extruder for recycling recycled plastics. Background Technology

[0002] Recycled plastic extrusion technology is the core process for realizing plastic recycling. Its key lies in transforming recycled waste plastics into reusable granules through steps such as melting, extrusion, and granulation.

[0003] Existing technology CN201921865385.2 includes a base, with a support column fixedly connected to the top of the base. A barrel is fixedly connected to the top of the support column, and a screw is rotatably connected inside the barrel. An upper pulley is positioned on one side of the barrel corresponding to the screw. This existing technology primarily addresses the automatic feeding of raw materials. However, in practical applications, recycled plastics are typically waste materials of various types and forms. When directly fed into the extruder, large particles, due to their small surface area, experience melting delays. When mixed with fine particles, they easily form unmelted lumps, affecting the final extrusion quality. Traditional equipment usually requires multiple drive devices to coordinate the plastic extrusion, significantly increasing equipment costs.

[0004] Therefore, it is necessary to provide a semi-automatic extruder for recycling plastics, which can achieve uniform mixing and save costs. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0022] 1. This invention, by incorporating a crushing component and a filter plate, ensures that incompletely crushed plastic particles, due to their large size, remain on the filter plate and are pushed back for continued crushing, thus guaranteeing uniform particle size entering the screw drum and reducing the scrap rate. The feeding component, via a conveyor belt, enables low-level feeding, eliminating the need for manual loading but eliminating the need for loading from higher positions. This semi-automatic operation improves safety and reduces manpower. Simultaneously, while the rotating shaft drives the crushing component, a scraping component cleans metal impurities from the inner wall of the mixing drum, and an adsorption component instantly removes metal debris, achieving simultaneous crushing and impurity removal.

The crushing component pre-crushes the recycled plastic before it enters the filtration stage. The rotating shaft drives the cam of the vibration component to rotate. The cam, positioned between two filter plates, impacts the two plates back and forth, thereby improving the filtration effect. By using two filter plates, the recycled plastic is sorted: the upper layer intercepts large, uncrushed particles, the middle layer of qualified particles enters the extrusion section, and the bottom layer collects metallic impurities. Finally, the rotating component performs rotational thermal extrusion of the plastic particles. The device uses only one motor to achieve crushing, vibration, and rotation, significantly saving costs and reducing equipment requirements. Attached Figure Description

[0035] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0036] Please see Figure 1-8 The present invention provides a technical solution: a semi-automatic extruder for recycling plastics, comprising a base 1, a screw cylinder 402, and an extrusion head 403. A motor 2 is fixedly connected to the bottom inner part of the base 1. A rotating shaft 201 is fixedly connected to the output end of the motor 2. A crushing component is connected to the top of the rotating shaft 201. A vibration component is connected to the middle part of the rotating shaft 201. A rotating component is connected to the bottom of the rotating shaft 201.

[0037] A mixing drum 304 is fixedly connected to the top of the base 1. The crushing component is located inside the mixing drum 304. A storage frame 114 is provided on one side of the base 1. A feeding component is provided inside the storage frame 114. The feeding component corresponds to the mixing drum 304.

[0038] The base 1 is equipped with a filter plate 102, a filter plate 103 and a collection plate 105. The vibration component is located in the middle of the filter plate 102 and the filter plate 103, corresponding to the filter plate 102 and the filter plate 103. The collection plate 105 is located at the bottom.

[0039] A long rod 4 is connected to one side of the rotating assembly, and a spiral blade 401 is connected to the outside of the long rod 4. The spiral blade 401 is located inside the spiral cylinder 402, and the spiral cylinder 402 is connected to the extrusion head 403.

[0040] Specifically, when the staff prepares to begin processing recycled plastics, the recycled plastics are initially placed inside the storage bin 114. The staff opens the feeding assembly and feeds the plastics onto it. The feeding assembly then conveys the plastics upwards into the mixing drum 304. At this point, the bottom of the mixing drum 304 is closed, and the recycled plastics are inside. Then, the staff turns on motor 2, causing the rotating shaft 201 to rotate. This rotation drives the crushing assembly, vibration assembly, and rotating assembly to operate. The crushing assembly crushes the plastics inside the mixing drum 304. After a short time, the plastics inside the mixing drum 304 are then sent down for filtration. Qualified particles are fed onto filter plate 103, while oversized particles are fed onto filter plate 102 and pushed into the storage frame 114 for further crushing. During the crushing process, vibration and rotation have already begun pre-running. As the plastic is fed to the bottom, the filter plates begin filtering. The vibration component strikes the two filter plates sequentially to improve their filtration efficiency. Simultaneously, the relatively small metal impurities in the plastic particles will pass through the two filter plates and reach the collection plate 105. Qualified particles are then fed through filter plate 103 into the rotating component, where heating is provided. The spiral blades 401 rotate and mix the particles before extrusion through the extruder 403. With a feeding component and a crushing component, the raw material is conveyed to the mixing drum 304 by the feeding component and pre-crushed by the crushing component. Large, unprocessed particles are returned for further processing after vibrating screening, ensuring the uniformity of particles entering the rotating component. The crushing, vibration, and rotation processes can be completed by a single motor 2, reducing production costs.

[0041] Filter plate 102 has a large aperture for preliminary screening of plastic particles, while filter plate 203 has a small aperture, allowing appropriately sized plastic particles to remain on the surface of filter plate 203, thus filtering out metallic impurities. Filter plate 203 is placed at an angle. Both filter plate 102 and filter plate 203 are inserted into the base 1. Sealing block 104 is provided at the connection between filter plate 102 and filter plate 203 and the rotating shaft 201.

[0042] Specifically, since it's recycled plastic, which comes in various sizes and shapes, it undergoes pretreatment before being heated, stirred, and extruded into the spiral blade 401. This ensures more uniform extrusion and improves the extrusion effect. Therefore, the recycled plastic needs to be crushed first. During this crushing process, large pieces often remain. The first filter plate 102 acts as a preliminary sieve, leaving the large plastic pieces on its surface. These large pieces are then sent out of the base 1 and re-entered for crushing along with the remaining plastic particles. Particles falling onto the second filter plate 103, along with some residual metal impurities, are filtered by the second filter plate 103 to the bottom collection plate 105. Appropriately sized plastic particles remain on the surface of the second filter plate 103. Since the second filter plate 103 is inclined, the plastic particles slide down the angle and fall into the spiral drum 402. The sealing block 104 is fixedly connected to the filter plate but rotatably connected to the rotating shaft 201, without affecting the rotation of the shaft. By setting up a double-layer filter plate, the plastic particle size is standardized, reducing energy fluctuations in heating and extrusion within the spiral drum 402, improving the uniformity of extrusion plasticization, and preventing large particles from being incompletely melted or small particles from being over-carbonized, thus reducing the defect rate.

[0043] A guide plate 110 is fixedly connected to one side of the filter plate 2 103. A slot is opened on one side of the base 1, through which the guide plate 110 passes. An opening is opened on one side of the top of the spiral cylinder 402, and the guide plate 110 and the opening correspond to each other.

[0044] Specifically, the plastic particles on the filter plate 103 will slide down into the spiral cylinder 402 along the inclined direction, that is, along the direction of the guide plate 110. In actual application, there is also a baffle above the guide plate 110, which is similar to a funnel, and the plastic particles enter the spiral cylinder 402 through its interior.

[0045] A long groove 108 is provided on one side of the filter plate 103, and a long block 109 is provided on one side of the long groove 108 to facilitate metal impurities falling into the collection plate 105. A cylinder is provided on one side of the collection plate 105, and a piston rod is connected to the output end of the cylinder. A push block is fixedly connected to one side of the piston rod. A waste trough 112 is provided on one side of the base 1, and the push block and the waste trough 112 correspond to each other.

[0046] Specifically, metallic impurities have a certain weight. Compared to plastic, normal metallic impurities are filtered to the bottom along the filter plate 103. Because the filter plate 103 is inclined, a small portion of the metallic impurities will move along the inclined direction. Since these metallic impurities are relatively small, they will fall off the long trough 108 when they reach it. The long block 109 acts as a shield to prevent metallic impurities from reaching the guide plate 110. The long block 109 is not set too high to obstruct the movement of the plastic particles.

[0047] A cylinder is fixedly connected to one side of the collecting plate 105. During operation, the piston rod extends, and the pusher block pushes and removes impurities from the collecting plate 105, sending them out through the waste trough 112 and away from the base 1. The rotating shaft 201 passes through the middle of the collecting plate 105; therefore, there are two cylinders, each positioned on one side, without affecting the rotating shaft 201. Operators can control the cylinders to automatically remove impurities from inside the collecting plate 105, reducing manpower requirements. Metal impurities are filtered to prevent extrusion defects caused by metal contamination.

[0048] The crushing component includes a crushing component 202, which is fixedly connected to a rotating shaft 201. A scraping component is connected to one side of the rotating shaft 201, which corresponds to the mixing drum 304. A suction component is connected to the top of the rotating shaft 201.

[0049] The vibration assembly includes a gear 204, which is fixedly connected to a rotating shaft 201. A gear 205 is meshed with one side of the gear 204. A support rod 106 is fixedly connected to the top of the collecting plate 105. A sealing block 107 is provided at the connection between the support rod 106 and the filter plate 103. The gear 205 and the support rod 106 are rotatably connected. A bevel gear 206 is fixedly connected to the top of the gear 205. A bevel gear 207 is meshed with one side of the bevel gear 206. A crossbar 208 is fixedly connected inside the bevel gear 207. The crossbar 208 is rotatably connected to the inside of the base 1. Two cams 209 are fixedly connected to the outside of the crossbar 208. The cams 209 correspond to the filter plate 102 and the filter plate 103.

[0050] The rotating assembly includes a pulley 210, which is fixedly connected to the rotating shaft 201. A support rod 101 is fixedly connected to the inner bottom of the base 1. A bevel gear 213 is rotatably connected to the top of the support rod 211. A pulley 211 is fixedly connected to the top of the bevel gear 213. A belt 212 is provided on the outer side of the pulleys 210 and 211. A bevel gear 214 is meshed with one side of the bevel gear 213. The bevel gear 214 is fixedly connected to the long rod 4.

[0051] Specifically, the recycled plastic is first fed into the mixing drum 304, which is closed at the bottom. When motor 2 is turned on, the rotating shaft 201 rotates, causing the crushing 202 to rotate as well, thus crushing the plastic inside. A scraping component on one side removes any metal impurities adsorbed on the inner wall, while an adsorption component sucks them out. After crushing for a while, the bottom of the mixing drum 304 opens, and the plastic particles enter the next filtration stage. At this point, the vibration and rotation components at the bottom begin pre-operation.

[0052] When the rotating shaft 201 rotates, it drives the gear 204, which is fixedly connected to it, to rotate. This causes the meshing gear 205 to rotate. Because gear 205 and support rod 106 are rotatably connected, and support rod 106 provides support for gear 205, the rotation of gear 205 causes bevel gear 206 to rotate. The meshing bevel gear 207 then causes the fixedly connected crossbar 208 to rotate. Therefore, the crossbar 208 is rotatably connected inside the base 1, thus enabling… The two cams 209 rotate, and the cams 209 are located in the middle of the two filter plates. As the cams 209 rotate, the convex part of the cam 209 reaches the upper end and strikes the upper filter plate 102, and the convex part of the cam 209 reaches the lower end and strikes the lower filter plate 103. This repeated striking makes the particles on the filter plates more thoroughly filtered, while ensuring that the particles on the second filter plate 103, which is the inclined plate, can be smoothly discharged. The sealing block 107 and the sealing block 104 have the same function.

[0053] When the rotating shaft 201 rotates, it drives the pulley 210, which is fixedly connected to it, to rotate. Driven by the belt 212, the pulley 211 also rotates, which in turn drives the bevel gear 213. The bevel gear 213 is rotatably connected to the support rod 101, so its rotation drives the bevel gear 214, which in turn drives the long rod 4, which is fixedly connected to it, to rotate. The spiral blade 401 also rotates. During operation, the inside of the spiral cylinder 402 is heated to melt the plastic, and the rotation mixes the plastic. The side wall of the base 1 provides support for the long rod 4, and the inside of the spiral cylinder 402 also provides support, ensuring the long rod 4 can rotate normally. By using a single motor 2 to simultaneously drive the crushing, vibration, and rotation movements, costs are greatly reduced, and space is saved.

[0054] The scraping assembly includes a scraping block 203, which is fixedly connected to a rotating shaft 201. The upper part of the rotating shaft 201 is hollow. The scraping block 203 has multiple ventilation holes 218 inside. The interior of the scraping block 203 is connected to the upper part of the rotating shaft 201. A stop block 219 is connected to the bottom of the scraping block 203. Magnetic material is provided on the inner side of the stirring cylinder 304 to adsorb metal impurities.

[0055] The suction assembly includes a dust pump 216, which is fixedly connected to one side of the mixing drum 304. A dust outlet pipe 217 is connected to one side of the dust pump 216, and a dust inlet pipe 215 is connected to the other side of the dust pump 216. The dust inlet pipe 215 is connected to the top of the rotating shaft 201.

[0056] Specifically, when the rotating shaft 201 rotates, the scraper block 203 rotates accordingly. The scraper block 203 adheres to the inner wall of the mixing drum 304. During the mixing process, metal impurities will be adsorbed onto the inner wall. Because there is a magnetic material (magnetic rubber liner) on the inner wall, the scraper block 203 can scrape them off. There is also a stop block 219 at the bottom of the scraper block 203 to prevent the metal impurities scraped onto the scraper block 203 from falling off. In this way, the metal impurities will at least fall onto the stop block 219, making it easier for the suction component to suction them off.

[0057] When suction is required, the dust pump 216 is turned on, the dust inlet pipe 215 draws in air, and then the air is drawn into the scraping block 203 through the inside of the top of the rotating shaft 201. The scraped metal impurities are then sucked away and removed through multiple vent holes 218. The dust outlet pipe 217 is connected to the impurity collection section.

[0058] By incorporating magnetic attraction and mechanical scraping, the impurity removal rate is improved. Combined with the suction component, this achieves effective removal of impurities.

[0059] Both the base 1 and the mixing drum 304 have discharge ports 113. The base 1 is fixedly connected to a cylinder 2. The output end of the cylinder 2 is connected to a piston rod 2. A closing block is fixedly connected to one side of the piston rod 2. The closing block corresponds to the discharge port 113.

[0060] Specifically, when the inside of the mixing drum 304 is being crushed, the discharge port 113 is closed. After crushing for a period of time, the cylinder 2 is opened, and the piston rod 2 at the output end retracts, taking the closing block away from the discharge port 113. That is, the closing block retracts into the inside of the upper plate of the base 1, and the cylinder is also fixed inside the upper plate. The staff controls the opening and closing of the discharge port 113.

[0061] A cylinder is provided on one side of the filter plate 102. A piston rod is connected to the output end of the cylinder. A feeding block is fixedly connected to one side of the piston rod. A feeding port 111 is opened on one side of the base 1. The feeding port 111 corresponds to the storage frame 114.

[0062] Specifically, a cylinder is fixedly connected to one side of the filter plate 102, which is also the side of the base 1. When it is necessary to feed the still relatively large plastic particles back for further crushing, the cylinder is opened, the piston rod at the output end extends, and the feeding block moves on top of the filter plate 102, thus pushing the particles to the feeding port 111 until they fall into the storage frame 114. The plastic particles inside the storage frame 114 are manually added to the feeding assembly by the operator. The rotating shaft 201 is located in the middle of the filter plate 102, so two cylinders are provided to scrape the filter plate 102 on both sides of the rotating shaft 201. By setting up the filter plate 102 and the feeding block, the incompletely crushed plastic particles are fed back for further crushing, ensuring the uniformity of the thermally extruded particles and improving the quality of the product.

[0063] The feeding assembly includes a second motor 3. The output end of the second motor 3 is fixedly connected to a rotating rod 301. The top of the storage frame 114 is fixedly connected to a side plate 306. The rotating rod 301 and the side plate 306 are rotatably connected. A first roller is fixedly connected to the outside of the rotating rod 301. A second roller is provided on the other side of the first roller. The second rotating rod is fixedly connected to the inside of the second roller. The second rotating rod and the side plate 306 are rotatably connected. A conveyor belt 302 is connected to the outside of the first roller and the second roller. Multiple long plates 303 are connected to the outside of the conveyor belt 302. The top of the mixing drum 304 is provided with a feed inlet 305, which corresponds to the long plates 303.

[0064] Specifically, when the staff prepares to load the material, they turn on motor 2 (3), and the rotating rod 1 (301) rotates. As the roller rotates, under the drive of the conveyor belt 302, the upper roller 2 also rotates. The rotating rod 2 rotates, and the long plates 303 on the outer side of the conveyor belt 302 move upward and downward one by one. At this time, the staff places the plastic on the long plates 303, which can then be conveyed to the top and delivered into the mixing drum 304. The device is not fully automated, but it eliminates the need for staff to directly feed the plastic to the top. They only need to load the material from below, saving manpower.
