Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separation of modified plastic particles, in particular to a high-efficiency magnetic separation device for modified plastic particles. Background Art

[0002] During the production process of modified plastics, some metal components need to be added to the plastic to improve the rigidity of the plastic after modification and increase the structural strength of the finished product. However, some metal components are not fully integrated during the plastic modification and mixing process. Therefore, the modified plastic particles produced will contain some metal particles of similar size to the modified plastic. The modified plastic particles need to be poured into a magnetic separation device to separate and remove the metal particles in the modified plastic particles to ensure the quality of the modified plastic particles.

[0003] The Chinese patent "A magnetic device for collecting impurities in the production of modified plastics" with authorization announcement number "CN216173189U" uses a rotating rod, a stirring column, a sieve plate and a leakage hole to achieve uniform feeding of modified plastics, ensuring the magnetic separation effect of the magnetic separation device on modified plastic particles.

[0004] However, during the stirring process of the rotating rod and the stirring column, the modified plastic particles may gather around the leak hole. This accumulation may hinder the subsequent falling of the modified plastic particles and gradually form a blockage, thereby affecting the magnetic separation efficiency of the modified plastic particles.

[0005] Therefore, an efficient magnetic separation device for modified plastic particles is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present invention is to provide a high-efficiency magnetic separation device for modified plastic particles in order to solve the above problems, thereby improving the problem that the modified plastic particles are accumulated on the screen plate, thereby hindering the discharge of the modified plastic particles.

[0007] The present invention achieves the above-mentioned purpose through the following technical solutions: a high-efficiency magnetic separation device for modified plastic particles, comprising: a magnetic separation frame, the inner wall of the magnetic separation frame is rotatably connected to two first pulleys, a conveyor belt is connected between the surfaces of the two first pulleys, the inner wall of the magnetic separation frame is fixedly connected to an electromagnet, the front end of the magnetic separation frame is fixedly connected to a servo motor, the output shaft of the servo motor is fixedly connected to one end of one of the first pulleys, and the top of the magnetic separation frame is provided with an anti-blocking mechanism; wherein, the anti-blocking mechanism includes a feed frame fixedly connected to the top of the magnetic separation frame, the inner wall of the feed frame is rotatably connected to a toggle rod, the surface of the toggle rod is fixedly connected to an annularly distributed feed block, and the surface of the feed frame is provided with an anti-blocking component. By utilizing the toggle rod and the feed block, uniform feeding of the modified plastic particles in the feed frame is achieved, ensuring that the modified plastic particles are evenly dispersed on the conveyor belt, thereby ensuring the magnetic separation efficiency of the modified plastic particles.

[0008] Preferably, the anti-blocking assembly includes two first loosening blocks slidably connected to the inner wall of the blanking frame, with second loosening blocks fixedly connected to both sides of the first loosening blocks, and loosening rods fixedly connected to the tops of the second loosening blocks in equal rows. Utilizing the first and second loosening blocks and the loosening rods, the modified plastic particles in the blanking frame are loosened and unblocked, preventing blockage within the blanking frame and ensuring uniform material discharge within the blanking frame.

[0009] Preferably, the output shaft surface of the servo motor is fixedly connected to a second pulley, and there are two second pulleys, wherein the inner wall of one of the second pulleys is fixedly connected to the surface of the toggle rod, and a belt is connected for transmission between the surfaces of the two second pulleys.

[0010] Preferably, one end of the toggle lever is fixedly connected to an eccentric wheel, the front end of one of the first loosening blocks is fixedly connected to a driven frame, and one end of the eccentric wheel is slidably connected to the inner wall of the driven frame. Utilizing a servo motor, a second pulley, and a belt, the conveyor belt, the toggle lever, and the loosening rod operate simultaneously, ensuring consistent magnetic separation of the modified plastic particles. Utilizing the eccentric wheel and the driven frame, the first loosening block, the second loosening block, and the loosening rod can reciprocally loosen the modified plastic particles, ensuring uniform dispersion of the modified plastic particles within the blanking frame onto the conveyor belt.

[0011] Preferably, a stopper is fixedly connected to the inner side of the magnetic separation frame, so as to block the modified plastic particles falling onto the conveyor belt and prevent the modified plastic particles from splashing out of the magnetic separation frame.

[0012] Preferably, a plurality of limiting rods are fixedly connected to the top of the magnetic separation frame, and the inner wall of the driven frame is slidably connected to the surface of the limiting rods. The limiting rods are used to limit the moving driven frame and ensure that the driven frame does not deviate during movement.

[0013] Preferably, the surface of the digging block is curved in an arc shape. The digging block with an arc shape ensures that the digging block uniformly diverts the modified plastic particles during rotation, thereby ensuring the stability and continuity of the digging block in diverting the modified plastic particles.

[0014] Preferably, the top of the loosening rod is truncated cone-shaped, and the second loosening block is shaped like an isosceles triangle. Utilizing the truncated cone-shaped loosening rod and the isosceles triangle-shaped second loosening block prevents the modified plastic particles from being retained on the second loosening block and the loosening rod, thereby ensuring uniform discharge of the modified plastic particles within the discharge frame.

[0015] The beneficial effects of the utility model are:

[0016] By utilizing the toggle rod and the toggle block, the modified plastic particles in the blanking frame are uniformly discharged, ensuring that the modified plastic particles are evenly dispersed on the conveyor belt, thereby ensuring the magnetic separation efficiency of the modified plastic particles. By utilizing the first loosening block, the second loosening block and the loosening rod, the modified plastic particles in the blanking frame are loosened and unblocked, avoiding blockage in the blanking frame and ensuring uniform discharge in the blanking frame.

By using the eccentric wheel and the driven frame, the first loosening block, the second loosening block and the loosening rod can reciprocate to loosen the modified plastic particles, ensuring that the modified plastic particles in the unloading frame are evenly dispersed onto the conveyor belt.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] When implementing: Figure 1-4 As shown, a high-efficiency magnetic separation device for modified plastic particles includes: a magnetic separation frame 1, the inner wall of the magnetic separation frame 1 is rotatably connected to two first pulleys 2, a conveyor belt 3 is transmission-connected between the surfaces of the two first pulleys 2, the inner wall of the magnetic separation frame 1 is fixedly connected to an electromagnet 4, the front end of the magnetic separation frame 1 is fixedly connected to a servo motor 5, the output shaft of the servo motor 5 is fixedly connected to one end of one of the first pulleys 2, and the top of the magnetic separation frame 1 is provided with an anti-blocking mechanism 6; wherein, the anti-blocking mechanism 6 includes a blanking frame 61 fixedly connected to the top of the magnetic separation frame 1, the inner wall of the blanking frame 61 is rotatably connected to a toggle rod 62, the surface of the toggle rod 62 is fixedly connected to an annularly distributed toggle block 63, the surface of the blanking frame 61 is provided with an anti-blocking component 64, and the surface of the toggle block 63 is curved in an arc shape.

[0025] Two collecting frames are fixedly connected to the inner side of the magnetic separation frame 1 , and a scraper is fixedly connected to the inner side of the magnetic separation frame 1 , and the surface of the scraper contacts the surface of the conveyor belt 3 .

[0026] It should be noted that the electromagnet 4 and servo motor 5 described above are both relatively mature components in existing technology. The servo motor 5 can control speed and position with high accuracy, converting voltage signals into torque and speed to drive the controlled object. The specific model can be selected based on actual needs. The servo motor 5 and electromagnet 4 can be powered by either an internal power supply or mains electricity. The specific power supply method is selected based on the specific situation and is not detailed here.

[0027] When it is necessary to magnetically separate the modified plastic particles, the servo motor 5 and the electromagnet 4 are manually turned on. The output shaft of the servo motor 5 rotates to drive the corresponding first pulley 2 to rotate and drive the toggle rod 62 to rotate. The corresponding first pulley 2 rotates to drive the conveyor belt 3 to transport and pour the modified plastic particles into the blanking frame 61. The toggle rod 62 rotates to drive the modified plastic particles in the blanking frame 61 to be evenly transferred to the bottom of the blanking frame 61, so that the modified plastic particles are evenly dispersed on the conveyor belt 3. During the transmission, the conveyor belt 3 drives the modified plastic particles to be transported to the collection frame. At this time, the electromagnet 4 begins to adsorb the metal particles. The plastic particles that are not adsorbed fall into one of the collection frames due to their own gravity. When the metal particles adhered to the conveyor belt 3 are transported to the bottom of the blanking frame 61, the magnetic force of the electromagnet 4 located below the blanking frame 61 is weak, and then they are scraped to another collection frame by the scraper. When it is no longer necessary to magnetically separate the modified plastic particles, the servo motor 5 and the electromagnet 4 are manually turned off.

[0028] like Figure 2-3 As shown, the anti-blocking component 64 includes two first loose blocks 649 slidably connected to the inner wall of the blanking frame 61, and the two sides of the first loose block 649 are fixedly connected to the second loose blocks 641. The top of the second loose block 641 is fixedly connected to the loose rods 642 distributed in an equal row. The top of the loose rod 642 is truncated. The shape of the second loose block 641 is an isosceles triangle. The output shaft surface of the servo motor 5 is fixedly connected to the second pulley 643. The number of the second pulley 643 is two, one of which is fixed to the second pulley 643. The inner wall of the second pulley 643 is fixedly connected to the surface of the toggle rod 62, and a belt 644 is connected between the surfaces of the two second pulleys 643. One end of the toggle rod 62 is fixedly connected to the eccentric wheel 646. The front end of one of the first loose blocks 649 is fixedly connected to the driven frame 645, and one end of the eccentric wheel 646 is slidably connected to the inner wall of the driven frame 645. Several limiting rods 648 are fixedly connected to the top of the magnetic separation frame 1, and the inner wall of the driven frame 645 is slidably connected to the surface of the limiting rod 648.

[0029] The output shaft of the servo motor 5 rotates to drive the corresponding second pulley 643 to rotate, and the corresponding second pulley 643 rotates to drive another second pulley 643 to rotate through the belt 644. The rotation of the second pulley 643 drives the toggle rod 62 and the eccentric wheel 646 to rotate. The rotation of the toggle rod 62 drives multiple toggle blocks 63 to rotate. The rotation of the eccentric wheel 646 drives the driven frame 645 to rise and fall back and forth. The reciprocating rise and fall of the driven frame 645 drives the first loosening block 649, the second loosening block 641 and the loosening rod 642 to reciprocately loosen the modified plastic particles in the blanking frame 61, so that the modified plastic particles fall evenly onto the conveyor belt 3.

[0030] like Figure 2As shown, a stopper 647 is fixedly connected to the inner side of the magnetic separation frame 1. The stopper 647 is used to prevent the modified plastic particles on the conveyor belt 3 from falling out of the blanking frame 61.

[0031] When the utility model is in use, the servo motor 5 and the electromagnet 4 are manually turned on, the output shaft of the servo motor 5 rotates to drive the corresponding first pulley 2 and the corresponding second pulley 643 to rotate simultaneously, the corresponding second pulley 643 rotates to drive the toggle rod 62 and the eccentric wheel 646 to rotate, the corresponding first pulley 2 rotates to drive the conveyor belt 3 to transport, and the modified plastic particles are poured into the blanking frame 61, the toggle rod 62 rotates to drive the modified plastic particles in the blanking frame 61 to be evenly transferred to the bottom of the blanking frame 61, and the eccentric wheel 646 rotates to drive the first loose block 649 and the second loose block 641 through the driven frame 645. The modified plastic particles in the discharge frame 61 are loosened reciprocally with the loosening rod 642, so that the modified plastic particles are evenly dispersed on the conveyor belt 3. The conveyor belt 3 drives the modified plastic particles to be transported to the collection frame during transportation. At this time, the electromagnet 4 begins to adsorb the metal particles. The plastic particles that are not adsorbed fall into one of the collection frames due to their own gravity. When the metal particles adhered to the conveyor belt 3 are transported to the bottom of the discharge frame 61, the magnetic force of the electromagnet 4 located below the discharge frame 61 is weak, and then the particles are scraped to another collection frame through the scraper. When there is no need to magnetically separate the modified plastic particles, the servo motor 5 and the electromagnet 4 are manually turned off.

[0032] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
