[0019] Please refer to Figure 1-8 , the present invention provides a technical solution: a semi-automatic extruder for recycling and regenerating plastics, comprising a base 1, a screw cylinder 402, and an extrusion head 403. A first motor 2 is fixedly connected to the inner bottom of the base 1. The output end of the first motor 2 is fixedly connected to a rotating shaft 201. A crushing assembly is connected to the top of the rotating shaft 201. A vibration assembly is connected to the middle of the rotating shaft 201. A rotating assembly is connected to the bottom of the rotating shaft 201; A mixing cylinder 304 is fixedly connected to the top of the base 1. The crushing assembly is located inside the mixing cylinder 304. A storage bin 114 is arranged on one side of the base 1. A feeding assembly is arranged inside the storage bin 114. The feeding assembly corresponds to the mixing cylinder 304; A first filter plate 102, a second filter plate 103, and a collection plate 105 are arranged inside the base 1. The vibration assembly is located in the middle of the first filter plate 102 and the second filter plate 103 and corresponds to the first filter plate 102 and the second filter plate 103. The collection plate 105 is located at the bottom; A long rod 4 is connected to one side of the rotating assembly. A spiral blade 401 is connected to the outside of the long rod 4. The spiral blade 401 is located inside the screw cylinder 402. The screw cylinder 402 is connected to the extrusion head 403.
[0020] Specifically, when the staff is ready to start the recycled plastic treatment, initially, the recycled plastics are placed inside the storage bin 114. The staff turns on the feeding component to send the plastics onto the feeding component, and then the feeding component conveys the plastics upward and sends them into the mixing drum 304. At this time, the bottom of the mixing drum 304 is closed, and the recycled plastics are inside the mixing drum 304. Then the staff turns on the first motor 2, and the rotating shaft 201 rotates. When rotating, it drives the crushing component, the vibration component, and the rotating component to start operating. The crushing component crushes the plastics inside the mixing drum 304. After a while, the plastics inside the mixing drum 304 can be sent down for filtration. The qualified particles will be sent onto the second filter plate 103, and the over-sized particles will be on the first filter plate 102 and will be pushed into the storage bin 114 for re-crushing. When the crushing component is crushing, the vibration and rotation have started pre-operation. When the plastics are sent down, the filter plates start to filter. The vibration component sequentially knocks on the two filter plates to improve the filtering effect of the filter plates. At the same time, the metal impurities in the plastic particles are theoretically relatively small and will pass through the two layers of filter plates and be filtered into the collection plate 105. The qualified particles pass through the second filter plate 103 and are sent into the rotating component. There is heating inside, and the spiral blades 401 rotate and mix the particles inside, and finally extrude through the extrusion head 403. By setting up the feeding component and the crushing component, after the raw materials are conveyed to the mixing drum 304 by the feeding component, they are pre-crushed by the crushing component, and the unprocessed large particles are returned for re-treatment after vibration screening, ensuring the uniformity of the particles entering the rotating component. The processes of crushing, vibration, and rotation can be completed with only one first motor 2, reducing the production cost.
[0021] The first filter plate 102 has large apertures and is used for initially screening plastic particles. The second filter plate 103 has small apertures. Plastic particles of appropriate size remain on the surface of the second filter plate 103, filtering out the metal impurities therein. The second filter plate 103 is inclined. Both the first filter plate 102 and the second filter plate 103 are inserted into the inside of the base 1. Sealing blocks 104 are provided at the connection points of the first filter plate 102 and the second filter plate 103 with the rotating shaft 201.
[0022] Specifically, since it is recycled plastic with plastics of different sizes and shapes, it needs to be pretreated before being heated, stirred and extruded into the spiral blade 401, so that it can be extruded more evenly and the extrusion effect can be improved. Therefore, it is necessary to first break up the recycled plastic. However, during the breaking process, there will still be large chunks remaining. Therefore, the first filter plate 102 plays a role in initially screening the particles. The large chunks of plastic remain on the surface of the filter plate 102 and are then sent out of the base 1 and re-entered together with the plastic particles to be processed for breaking. The particles that fall onto the second filter plate 103 may also have some remaining metal impurities and the like. Such impurities will be filtered by the second filter plate 103 to the bottom collecting plate 105, while the plastic particles of appropriate size remain on the surface of the second filter plate 103. The second filter plate 103 is inclined, so that the plastic particles will slide along the angle and fall into the inside of the spiral cylinder 402. The first sealing block 104 is fixedly connected to the filter plate and rotationally connected to the rotating shaft 201, without affecting the rotation of the rotating shaft 201. By providing a double-layer filter plate, the particle size of the plastic particles is standardized, the energy fluctuation of heating and extrusion in the spiral cylinder 402 is reduced, the extrusion and plasticization uniformity is improved, and at the same time, large particles are prevented from being incompletely melted or small particles from being over-carbonized, reducing the defective rate.
[0023] One side of the second filter plate 103 is fixedly connected with a deflector 110. A notch is provided on one side of the base 1. The deflector 110 passes through the notch. An opening is provided on one side of the top of the spiral cylinder 402, and the deflector 110 corresponds to the opening.
[0024] Specifically, the plastic particles on the second filter plate 103 will slide along the inclined direction, that is, along the direction of the deflector 110, into the inside of the spiral cylinder 402. In actual application, there is also a baffle above the deflector 110, which is similar to a funnel, and the plastic particles enter the inside of the spiral cylinder 402 along it.
[0025] A long groove 108 is provided on one side of the second filter plate 103. A long block 109 is provided on one side of the long groove 108 to facilitate the metal impurities to fall into the inside of the collecting plate 105. A first cylinder is provided on one side of the collecting plate 105. The output end of the first cylinder is connected with a first piston rod. A first pushing block is fixedly connected to one side of the first piston rod. A waste material groove 112 is provided on one side of the base 1, and the first pushing block corresponds to the waste material groove 112.
[0026] Specifically, metal impurities have a certain weight. Compared with plastics, normal metal impurities filter down to the bottom along the second filter plate 103. Since the second filter plate 103 is inclined, a small part of the metal impurities will move along the inclined direction. And the metal impurities are also relatively small. Therefore, when moving, when reaching near the long groove 108, they will fall from the long groove 108. The long block 109 plays a role in blocking, preventing metal impurities from reaching the diversion plate 110. The long block 109 is not set too high and will not block the moving direction of plastic particles.
[0027] Inside one side of the collection plate 105 is fixedly connected with the first cylinder. When working, the piston rod of the first cylinder extends out, and the push block pushes the impurities on the collection plate 105 to be cleared and sent out from the waste material groove 112, leaving the base 1. In the middle of the collection plate 105 passes through the rotating shaft 201. Therefore, there are two first cylinders, and this cleaning device is respectively arranged on both sides without affecting the rotating shaft 201. The staff can control the first cylinder to automatically clear the impurities inside the collection plate 105, reducing the manpower. Filter the metal impurities to avoid defects in the extruded products caused by metal contamination.
[0028] The crushing assembly includes the crushing pieces 202. The crushing pieces 202 are fixedly connected with the rotating shaft 201. One side of the rotating shaft 201 is connected with a scraping assembly, and the scraping assembly corresponds to the stirring cylinder 304. The top of the rotating shaft 201 is connected with a suction assembly; The vibration assembly includes the first gear 204. The first gear 204 is fixedly connected with the rotating shaft 201. One side of the first gear 204 is meshed and connected with the second gear 205. The top of the collection plate 105 is fixedly connected with the first support rod 106. A sealing block 107 is arranged at the connection between the first support rod 106 and the second filter plate 103. The second gear 205 is rotatably connected with the first support rod 106. The top of the second gear 205 is fixedly connected with the first bevel gear 206. One side of the first bevel gear 206 is meshed and connected with the second bevel gear 207. The inside of the second bevel gear 207 is fixedly connected with the cross bar 208. The cross bar 208 is rotatably connected with the inside of the base 1. Two cams 209 are fixedly connected to the outside of the cross bar 208, and the cams 209 correspond to the first filter plate 102 and the second filter plate 103; The rotating assembly includes the first pulley 210. The first pulley 210 is fixedly connected with the rotating shaft 201. The inner bottom of the base 1 is fixedly connected with the second support rod 101. The top of the second support rod 101 is rotatably connected with the third bevel gear 213. The top of the third bevel gear 213 is fixedly connected with the second pulley 211. A belt 212 is arranged outside the first pulley 210 and the second pulley 211. One side of the third bevel gear 213 is meshed and connected with the fourth bevel gear 214. The fourth bevel gear 214 is fixedly connected with the long rod 4.
[0029] Specifically, first, the recycled plastic is sent into the interior of the mixing drum 304. At this time, the bottom of the mixing drum 304 is closed. The first motor 2 is turned on, and the rotating shaft 201 rotates, driving the shredding piece 202 to rotate, so that the plastic inside can be shredded. The scraping component on one side can scrape the metal impurities adsorbed on the inner wall, and the adsorption component can suck out the metal impurities. After shredding for a while, the bottom of the mixing drum 304 is opened, and the plastic particles enter the next filtering stage. At this time, the vibration component and the rotating component at the bottom have started pre-operation.
[0030] When the rotating shaft 201 rotates, it drives the first gear 204 fixedly connected thereto to rotate. In this way, the meshing-connected second gear 205 can rotate. Since the second gear 205 is rotatably connected to the first support rod 106, the first support rod 106 provides a certain supporting force for the second gear 205. When the second gear 205 rotates, it drives the first bevel gear 206 to rotate. The meshing-connected second bevel gear 207 drives the fixedly connected cross bar 208 to rotate. Therefore, the cross bar 208 is rotatably connected inside the base 1 and can thus rotate. In this way, the two cams 209 will rotate. The cams 209 are located in the middle of the two filter plates. As the cams 209 rotate in circles, when the convex part of the cam 209 reaches the upper end, it strikes the upper filter plate 102, and when the convex part of the cam 209 reaches the lower end, it strikes the lower filter plate 103. Just like this, through reciprocating knocking, the particles on the filter plate are filtered more thoroughly, and at the same time, it is ensured that the particles on the filter plate 103, that is, the inclined plate, can be smoothly sent out. The functions of the second sealing block 107 and the first sealing block 104 are the same.
[0031] When the rotating shaft 201 rotates, it drives the first pulley 210 fixedly connected thereto to rotate. Under the drive of the belt 212, the second pulley 211 will also rotate accordingly, driving the third bevel gear 213 to rotate. The third bevel gear 213 is rotatably connected to the second support rod 101. Therefore, the third bevel gear 213 can rotate, driving the fourth bevel gear 214 to rotate. The fixedly connected long rod 4 rotates, and the spiral blade 401 rotates. During operation, the inside of the spiral cylinder 402 is heated to heat the plastic, and rotation is used to mix the plastic. The side wall of the base 1 provides a certain support for the long rod 4, and the inside of the spiral cylinder 402 also provides a certain support for it to ensure that the long rod 4 can rotate normally. By using a single first motor 2 to drive three motions, namely shredding, vibration, and rotation, the cost is greatly saved, and at the same time, space is saved.
[0032] The scraping component includes a scraping block 203. The scraping block 203 is fixedly connected to the rotating shaft 201. The upper part of the rotating shaft 201 is hollow inside. A plurality of ventilation holes 218 are provided inside the scraping block 203. The inside of the scraping block 203 communicates with the upper part of the rotating shaft 201. A stop block 219 is connected to the bottom of the scraping block 203. A magnetic material is provided on the inner side of the mixing drum 304 for adsorbing metal impurities. The suction component includes a dust removal pump 216. The dust removal pump 216 is fixedly connected to one side of the mixing drum 304. An outlet pipe 217 is connected to one side of the dust removal pump 216. An inlet pipe 215 is connected to the other side of the dust removal pump 216. The inlet pipe 215 is connected to the top of the rotating shaft 201.
[0033] Specifically, when the rotating shaft 201 rotates, the scraping block 203 rotates accordingly. The scraping block 203 fits against the inner wall of the mixing drum 304. During the mixing process, metal impurities will be adsorbed on the inner wall. Since there is a magnetic material (magnetic rubber lining) on the inner wall, the scraping block 203 can scrape it. There is also a stop block 219 at the bottom of the scraping block 203 to prevent the metal impurities scraped onto the scraping block 203 from falling. In this way, the metal impurities at least fall on the stop block 219, facilitating the suction component to suck them out.
[0034] When suction is required, the dust removal pump 216 is turned on. The inlet pipe 215 sucks air, and then sucks through the inside of the top of the rotating shaft 201 into the inside of the scraping block 203. The scraped metal impurities are sucked away and removed through the plurality of ventilation holes 218. The outlet pipe 217 is connected to the part for collecting impurities.
[0035] By setting magnetic attraction plus mechanical scraping, the impurity removal rate is improved. Coupled with the suction component, effective removal of impurities is achieved.
[0036] Discharge ports 113 are provided at the joints between the base 1 and the mixing drum 304. A second cylinder is fixedly connected inside the base 1. The output end of the second cylinder is connected to a second piston rod. A closing block is fixedly connected to one side of the second piston rod. The closing block corresponds to the discharge port 113.
[0037] Specifically, when the inside of the mixing drum 304 is being crushed, the discharge port 113 is closed at this time. After crushing for a period of time, the second cylinder is opened at this time. The second piston rod at the output end retracts, driving the closing block away from the discharge port 113, that is, the closing block retracts into the upper plate of the base 1. The cylinder is also fixed inside the upper plate, and the staff controls the opening and closing of the discharge port 113.
[0038] A cylinder three is arranged on one side of the filter plate one 102, the output end of the cylinder three is connected to a piston rod three, one side of the piston rod three is fixedly connected to a feeding block, a feeding port 111 is opened on one side of the base 1, and the feeding port 111 corresponds to the storage frame 114.
[0039] Specifically, one side of the filter plate 102, that is, the side of the base 1, is fixedly connected with a cylinder 3. When the plastic particles with larger size need to be sent back for crushing, the cylinder 3 is opened, the piston rod 3 at the output end extends, and the feeding block moves on the top of the filter plate 102, thereby pushing the particles to the feeding port 111 until they fall into the inside of the storage frame 114. The plastic particles inside the storage frame 114 are manually added to the feeding assembly by the staff. The middle part of the filter plate 102 is the rotating shaft 201, so two cylinders 3 are provided to scrape the filter plate 102 on both sides of the rotating shaft 201. By providing the filter plate 102 and the feeding block, the plastic particles that are not completely crushed are sent back for crushing, which ensures the uniformity of the particles extruded by thermal extrusion and improves the quality of the product.
