Description

Technical Field

[0001] This utility model relates to the field of plastic processing, and in particular to a plastic particle iron removal machine. Background Technology

[0002] Plastic particles, also known as plastic granules, are raw materials for storing, transporting, and processing plastics in a semi-finished form. During the processing of plastic particles, small metal fragments may be mixed into the granulator. During the granulation process, smaller metal fragments may be mixed into the molten material and formed in the plastic particles. Therefore, it is necessary to remove iron from the plastic particles by screening.

[0003] For example, patent document CN222886152U discloses a plastic particle iron removal machine. The feeding mechanism divides the plastic particles into two parts and enters the iron removal mechanism. Under the action of the feeding mechanism, the plastic particles slide on the slide table in a flat manner. The magnetic blocks adsorb the metal fragments contained in the plastic particles. Multiple magnetic blocks work together to perform all-round iron removal screening of the plastic particles. The feeding mechanism moves the plastic particles through the feeding roller. Since a large number of plastic particles are concentrated at the feeding roller, the feeding roller will move a bunch of plastic particles when it rotates, which cannot make the plastic particles spread evenly. This may result in incomplete iron removal and affect the iron removal effect. Utility Model Content

[0004] The purpose of this invention is to provide a plastic particle iron removal machine to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A plastic particle iron removal machine includes two frame side plates, with a conveying mechanism and a discharge mechanism arranged between the frame side plates. A power mechanism is arranged on one side of the frame side plate, and a U-shaped frame is fixed on the frame side plate. The U-shaped frame is located above the conveying mechanism, and a dispersing mechanism is arranged inside the U-shaped frame. The dispersing mechanism includes two mounting plates distributed horizontally, and two dispersing plates distributed front and back are slidably connected between the two mounting plates. The bottom of the dispersing plates is set with a toothed structure, and the toothed structure density of the two dispersing plates is different. A rack is fixed on the adjacent surface of the two dispersing plates, and a gear meshes between the two racks. A drive shaft is fixed inside the gear, and both ends of the drive shaft are rotatably connected to the mounting plates. A conversion motor is fixed on one side of the mounting plate, and the output shaft of the conversion motor is fixedly connected to the drive shaft. A guide mechanism for moving the mounting plates is arranged on the top of the U-shaped frame, and a push-pull mechanism for driving the reciprocating motion of the guide mechanism is arranged on one side of the U-shaped frame.

[0007] Preferably, the guide mechanism includes a movable rod located above the U-shaped frame. Two sliders are fixedly connected to the movable rod. A through groove is provided at the top of the U-shaped frame. The sliders pass through the through groove and are fixedly connected to the mounting plate. The sliders are slidably connected in the through groove. A pin is fixed to the bottom of the end of the slider near the push-pull mechanism.

[0008] Preferably, the push-pull mechanism includes a first support, which is fixed to one side of the U-shaped frame. A drive motor is fixed to the top of the first support, and a turntable is fixed to the output shaft of the drive motor. A connecting rod is rotatably connected to the top edge of the turntable, and the other end of the connecting rod is rotatably connected to a pin.

[0009] Preferably, the conveying mechanism includes a conveying roller and a magnetic roller, which are rotatably connected between two frame side plates. A conveyor belt is fitted onto the conveying roller and the magnetic roller, with the magnetic roller located in front of the conveying roller.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-6 As shown, a plastic particle iron removal machine includes two frame side plates 1. A conveying mechanism 2 and a discharge mechanism 3 are arranged between the frame side plates 1. A power mechanism 8 is arranged on one side of the frame side plate 1. A U-shaped frame 4 is bolted to the frame side plate 1. The U-shaped frame 4 is located above the conveying mechanism 2. A dispersing mechanism 6 is arranged inside the U-shaped frame 4. The dispersing mechanism 6 includes two mounting plates 601 distributed horizontally. Two dispersing plates 602 distributed front-back are slidably connected between the two mounting plates 601. The bottom of the dispersing plates 602 is set with a toothed structure, and the toothed structure of the two dispersing plates 602 has a different density. By setting the toothed structure, the plastic particles can pass through in a single layer. When the dispersing plates 602 move back and forth, they can evenly disperse the plastic particles, making the plastic particles evenly spread. The adjacent surfaces of the two dispersing plates 602 are evenly distributed. A rack 603 is fixed, and a gear 604 meshes between the two racks 603. A drive shaft 605 is fixed inside the gear 604. Both ends of the drive shaft 605 are connected to the mounting plate 601 through bearings. A conversion motor 606 is bolted to one side of the mounting plate 601. The output shaft of the conversion motor 606 is fixedly connected to the drive shaft 605. The conversion motor 606 causes the gear 604 to rotate, and the gear 604 drives the two racks 603 to move in opposite directions, thereby switching the two dispersion plates 602. Since the tooth structure of the two dispersion plates 602 is different, it can adapt to plastic particles of different sizes and has stronger versatility. A guide mechanism 5 is provided on the top of the U-shaped frame 4 to drive the mounting plate 601 to move, and a push-pull mechanism 7 is provided on one side of the U-shaped frame 4 to drive the guide mechanism 5 to reciprocate.

[0026] The guide mechanism 5 includes a movable rod 501, which is located above the U-shaped frame 4. Two sliders 502 are welded on the movable rod 501. A through groove is provided at the top of the U-shaped frame 4. The sliders 502 pass through the through groove and are fixedly connected to the mounting plate 601. The sliders 502 are slidably connected in the through groove. A pin 503 is fixed at the bottom of one end of the slider 502 near the push-pull mechanism 7.

[0027] The push-pull mechanism 7 includes a first support 701, which is bolted to one side of the U-shaped frame 4. A drive motor 702 is bolted to the top of the first support 701. A turntable 703 is fixed to the output shaft of the drive motor 702. A connecting rod 704 is rotatably connected to the top edge of the turntable 703. The other end of the connecting rod 704 is rotatably connected to the pin 503. The drive motor 702 drives the turntable 703 to rotate, and the turntable 703 drives the connecting rod 704 to move. The connecting rod 704 drives the movable rod 501 to move back and forth. The movable rod 501 drives the mounting plate 601 to move back and forth through the slider 502, thereby causing the dispersing plate 602 to move back and forth.

[0028] The conveying mechanism 2 includes a conveying roller 201 and a magnetic roller 202, which are connected between two frame side plates 1 via bearings. A conveyor belt 203 is fitted onto the conveying roller 201 and the magnetic roller 202, with the magnetic roller 202 located in front of the conveying roller 201. A feed hopper 101 is screwed to the top of the frame side plate 1, located above the conveyor belt 203 and behind the U-shaped frame 4. Plastic particles fall onto the conveyor belt 203 through the feed hopper 101, and the conveyor belt 203 transports the plastic particles forward. The plastic particles are dispersed after passing through the dispersing plate 602. Plastic particles are evenly spread on the conveyor belt 203. When the plastic particles move to the magnetic roller 202, the iron impurities are adsorbed onto the conveyor belt 203 and transported to the bottom of the conveyor belt 203. When the iron impurities move away from the magnetic roller 202, they will automatically fall off. A guide plate 102 is fixedly connected between the two frame side plates 1. The guide plate 102 is located below the magnetic roller 202 and behind the discharge mechanism 3. The iron impurities fall onto the guide plate 102. An iron material box 9 is placed below the guide plate 102. Therefore, the iron impurities slide down the guide plate 102 into the iron material box 9, completing the collection of iron impurities.

[0029] The discharge mechanism 3 includes a drive roller 301 and a driven roller 302. The drive roller 301 and the driven roller 302 are connected between two frame side plates 1 by bearings. A discharge belt 303 is fitted on the drive roller 301 and the driven roller 302. The discharge belt 303 is located below the front end of the conveyor belt 203. The separated plastic particles fall directly from the conveyor belt 203 onto the discharge belt 303. The discharge belt 303 conveys the plastic particles forward and collects them manually.

[0030] The power mechanism 8 includes a second support 801, which is bolted to one side of the frame side plate 1. A conveyor motor 802 is bolted to the second support 801. The output shaft of the conveyor motor 802 is fixedly connected to the magnetic roller 202. A drive synchronous pulley 803 is fixed to one end of the magnetic roller 202. A synchronous belt 804 is connected to the drive synchronous pulley 803. A driven synchronous pulley 805 is connected to the lower end of the synchronous belt 804. The driven synchronous pulley 805 is fixedly connected to one end of the drive roller 301.

[0031] Working principle: The conveyor motor 802 drives the magnetic roller 202 to rotate. Through the transmission of the active synchronous pulley 803, the synchronous belt 804, and the driven synchronous pulley 805, the active roller 301 rotates synchronously with the magnetic roller 202, causing the conveyor belt 203 and the discharge belt 303 to operate synchronously, pouring plastic particles into the feed hopper 101. The plastic particles fall onto the conveyor belt 203 through the feed hopper 101, and the conveyor belt 203 conveys the plastic particles forward. When the plastic particles reach the dispersing plate 602, most of them are blocked, and a small portion of the plastic particles pass through the toothed structure at the bottom of the dispersing plate 602. At the same time, the drive motor 702 drives the turntable 703 to rotate. The turntable 703 drives the connecting rod 704 to move, and the connecting rod 704 drives the movable rod 501 to move back and forth left and right. The movable rod 501 drives the mounting plate 601 to move back and forth left and right through the slider 502, thereby causing the dispersing plate 602 to move back and forth left and right. The movement of the plastic particles ensures they are evenly distributed on the conveyor belt 203. When the plastic particles reach the magnetic roller 202, iron impurities are adsorbed onto the conveyor belt 203 and transported to the bottom. Once the iron impurities are away from the magnetic roller 202, they automatically fall off onto the feed hopper 101 and then slide down the guide plate 102 into the iron material box 9, completing the collection of iron impurities. The separated plastic particles fall directly from the conveyor belt 203 onto the discharge belt 303, which transports the plastic particles forward for manual collection. For plastic particles of different sizes, the switching motor 606 rotates the gear 604, which drives the two racks 603 to move in opposite directions, thereby switching the two dispersing plates 602. This ensures both the efficiency of plastic particle passage and the even distribution of the plastic particles.

[0032] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
