Description

Technical Field

[0001] The invention relates to the technical field of raw material conveying, and in particular to a raw material conveying and supplying device. Background Art

[0002] In today's era, the use of plastic products is everywhere. With the continuous expansion of the consumer market and the acceleration of product updates, the amount of waste plastics generated has risen sharply, resulting in a considerable amount of waste plastic resources. These waste plastics include various common plastic materials such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, etc., covering a variety of sources from daily packaging materials, plastic products to industrial plastic accessories. If these waste plastics are discarded at will, they will not only be difficult to degrade in the natural environment, exist for a long time and occupy a large amount of land resources, but also produce harmful substances through decomposition, causing serious pollution to the soil, water and air, and thus endangering the balance of the ecosystem and the survival and reproduction of organisms. Therefore, it is very important to recycle and reuse waste plastics.

[0003] At present, the main method of preliminary classification of plastics is through sorting equipment according to their types. Crusher is used to break large pieces of waste plastic into smaller pieces, and then impurities are removed with the help of cleaning equipment. After that, granulator is used to process the cleaned plastic fragments into recycled plastic particles, so as to facilitate the manufacture of various plastic products. However, these plastic particles are easily mixed with some metal impurities during the recycling process, or mixed with metal fragments produced by machine wear during the crushing process. During the injection molding or extrusion molding process, these metal impurities will cause defects in plastic products, reduce the mechanical properties of the products, and even damage the molding equipment.

[0012] As a further improvement of the above scheme, the magnetic separation component also includes a vibration mechanism, which includes a fixed plate and a vibration plate, the fixed plate is fixedly connected to the inside of the shell, the vibration plate is slidably connected to the inside of the shell and fits with the top inner wall of the conveyor belt, the top of the discharge box is symmetrically rotatably connected to a drive rod that penetrates into the shell, the drive rod and the cleaning roller are connected through a transmission system, the four corners on the upper surface of the fixed plate are fixedly connected to a limiting sleeve, a spring 2 is fixedly connected between the vibration plate and the limiting sleeve, and two cams are fixedly connected to the outside of the drive rod.

[0018] 1. The electromagnet located at the top of the raw material can be connected to electricity to form a larger magnetic field. When the raw material passes through the magnetic field, the metal impurities will be more fully affected by the magnetism and adsorbed on the electromagnet. In the process of the transmission belt driving multiple electromagnets to rotate in a cycle with the help of the mounting seat, new electromagnets will be continuously replaced to avoid the adverse effects of subsequent adsorption effects due to the adsorption of metal impurities on the electromagnet, thereby ensuring the treatment quality of metal impurities, further reducing the residual metal impurities, improving the quality of the finished plastic particles, and reducing the impact on the equipment.

[0019] 2. When the electromagnet moves to the inside of the discharge box, it will be powered off and demagnetized. In this case, larger metal impurities will fall accurately into the collection vehicle at the bottom due to their own greater gravity. However, smaller metal impurities cannot overcome the gradually decreasing magnetism of the electromagnet due to their own smaller gravity and will continue to move forward with the electromagnet. At this time, the cleaning roller that rotates synchronously with the electromagnet will drive the cleaning roller to rotate, thereby cleaning the fine raw materials at the bottom of the electromagnet and making them fall onto the screening plate at the bottom for screening, thereby improving the screening quality of metal impurities of different volumes.

[0020] 3. The rotating cleaning roller strikes the vibration plate through the cam on the driving rod, causing the vibration plate to start vibrating under the supporting connection of the second spring. The vibrating vibration plate will drive the top of the conveyor belt to vibrate, so as to separate the metal impurities from the raw materials, so that the electromagnet can more fully contact and adsorb the metal impurities, reducing the adverse effects of raw material accumulation on the electromagnet's adsorption of metal impurities.

DETAILED DESCRIPTION

[0035] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 7As shown, the present invention provides an embodiment: a raw material conveying and supplying device, including a shell 1, a conveyor belt 2 is arranged inside the shell 1, a lower hopper 3 is fixedly connected to the top of the shell 1, a magnetic separation component 4 is arranged on the top of the shell 1, and a collecting component 5 is arranged at the bottom of the magnetic separation component 4. The magnetic separation component 4 includes a support frame 1 41, a plurality of electromagnets 42, a support frame 2 43, a power supply mechanism 45 and a power receiving mechanism 46, the power supply mechanism 45 and the power receiving mechanism 46 are used to control the on and off of the electromagnet 42, the support frame 1 41 and the support frame 2 43 are fixedly connected to the top of the shell 1, the support frame 1 41 and the electromagnet 42 A transmission roller 48 is symmetrically connected to rotate between them, and a transmission belt 44 is symmetrically connected to the outer sides of the two transmission rollers 48. A plurality of mounting seats 49 are evenly and fixedly connected between the two transmission belts 44. The number of electromagnets 42 is equal to the number of mounting seats 49. The electromagnets 42 are fixedly connected to the outer side walls of the mounting seats 49. An annular groove is provided on the opposite sides of the support frame 1 41 and the support frame 2 43. The guide rod 461 and the power receiving seat 462 are respectively slidably connected in the two annular grooves. A stepper motor 6 is fixedly installed on the outer side of the support frame 1 41, and one end of one of the transmission rollers 48 is fixedly connected to the output end of the stepper motor 6.

[0037] The power supply mechanism 45 includes a power supply seat 451 fixedly connected to the bottom of the support frame 41, and power supply conductive strips 454 are symmetrically fixedly connected to the inner wall of the power supply seat 451. A power supply seat 452 is fixedly installed on the outer side of the power supply seat 451. The power supply seat 452 is electrically connected to the two power supply conductive strips 454 through the power supply sheet 453.

[0038] The power receiving mechanism 46 includes a guide rod 461 and a power receiving seat 462 which are symmetrically fixedly connected to the outer wall of the electromagnet 42. The power receiving seat 462 is symmetrically slidably connected to the power receiving ring 463 inside. The power receiving mechanism 46 also includes a power receiving sleeve 465 fixedly connected to the inside of the power receiving seat 462. The electromagnet 42 is electrically connected to the power receiving sleeve 465 through a wire 464. The inside of the power receiving sleeve 465 is symmetrically slidably connected with a conductive rod 466. The conductive rods 466 are fixedly connected to the power receiving ring 463. A spring 467 is fixedly connected between the power receiving ring 463 and the power receiving sleeve 465. The outer wall of the conductive rod 466 and the inner wall of the power receiving sleeve 465 are coated with conductive silver paste.

[0039] In practical application, the embodiment of the present invention is as follows: Figures 3 to 7As shown, when the transmission belt 44 rotates driven by the transmission roller 48, the electromagnet 42 on the mounting seat 49 moves accordingly. When the electromagnet 42 passes the position of the power supply mechanism 45, the power receiving seat 462 in the power receiving mechanism 46 slides in the annular groove and gradually approaches the power supply seat 451. As the distance approaches, the power receiving ring 463 in the power receiving seat 462 pushes the conductive rod 466 to approach the power supply strip 454 in the power supply seat 451 under the action of the spring 467. When the conductive rod 466 contacts the power supply strip 454, the current flows to the electromagnet 42 through the power supply seat 452, the power supply sheet 453, the power supply strip 454, the conductive rod 466, the power receiving ring 463, the power receiving sleeve 465 and the wire 464, so that the electromagnet 42 is energized to generate magnetism.

[0040] When the electromagnet 42 moves to the top of the housing 1 near the position above the conveyor belt 2, the energized electromagnet 42 generates an attraction force on the metal impurities in the raw materials on the conveyor belt 2, and the metal impurities are adsorbed on the surface of the electromagnet 42. As the transmission belt 44 continues to rotate, when the electromagnet 42 moves above the collection component 5, the power receiving mechanism 46 is separated from the power supply mechanism 45, the electromagnet 42 is powered off and loses its magnetism, and the metal impurities adsorbed on the electromagnet 42 fall into the collection component 5 under the action of gravity for collection;

[0041] Among them, the setting of multiple electromagnets 42 increases the adsorption area and adsorption points of metal impurities in the raw materials. When the raw materials on the conveyor belt 2 pass, more electromagnets 42 can contact the metal impurities more fully, thereby greatly improving the adsorption efficiency of the metal impurities, ensuring that as many metal impurities as possible are separated in time, and multiple electromagnets 42, driven by the transmission belt 44, can continuously adsorb and separate metal impurities. When a part of the electromagnets 42 are adsorbing metal impurities, the other part of the electromagnets 42 move to the collection component 5 to prepare for unloading, thereby improving the working efficiency of the entire classification and processing device, reducing the intermittent time caused by the operation of a single electromagnet 42, ensuring the smoothness of the processing process, and solving the problem that a single electromagnet 42 is prone to affect the subsequent adsorption effect due to the adsorption of too many metal impurities. In addition, multiple electromagnets 42 work together. Even if individual electromagnets 42 fail, other electromagnets 42 can continue to operate, and the entire classification and processing process will not be interrupted due to the failure of a single electromagnet 42, reducing the downtime and maintenance costs caused by equipment failure, and ensuring the screening efficiency and quality of the entire process.

[0042] like Figure 3 , Figure 8 , Fig.11 and Fig.12As shown, the collecting assembly 5 includes a discharge box 51 fixedly connected to the bottom of the supporting frame 1 41 and the supporting frame 2 43, the bottom of the discharge box 51 is slidably connected to the collecting vehicle 52, the top of the discharge box 51 is rotatably connected to the cleaning roller 54, the interior of the collecting vehicle 52 is fixedly connected to the partition 1 57, the interior of the discharge box 51 is fixedly connected to the screening plate 56 and the partition 2 58, the screening plate 56 is fixedly connected to the top of the partition 2 58 and is tilted, the cleaning roller 54 is connected to the driving roller 48 through the transmission system 2 55, the bottom of the discharge box 51 is symmetrically provided with square grooves, universal wheels 59 are fixedly installed at the four corners of the bottom of the collecting vehicle 52, the universal wheels 59 are slidably connected to the two square grooves in a group of two, and a handle 53 is fixedly connected to the outside of the collecting vehicle 52.

[0043] In actual application of the embodiment of the present invention, when the electromagnet 42 moves to the inside of the discharge box 51 and is powered off for demagnetization, the larger metal impurities fall accurately into the collection vehicle 52 under the action of their own gravity, while the smaller metal impurities cannot overcome the gradually decreasing magnetism of the electromagnet 42 due to their smaller gravity, and will continue to move with the electromagnet 42. At this time, the cleaning roller 54 that rotates synchronously with the electromagnet 42 rotates under the action of the transmission system 2 55 to clean the fine raw materials at the bottom of the electromagnet 42 and make them fall onto the screening plate 56 at the bottom. The screening plate 56 is tilted so that the smaller metal impurities that fall on it slide along its surface under the action of gravity. During the sliding process, metal impurities of different sizes are preliminarily screened under the action of the screening plate 56. Smaller metal impurities pass through the pores of the screening plate 56 or slide down to the specific area below the partition plate 58 along its inclined direction, while larger metal impurities are blocked above the screening plate 56 and gradually move to one side of the collecting vehicle 52. The universal wheels 59 at the four corners of the bottom of the collecting vehicle 52 slide in the square groove, so that the collecting vehicle 52 can move stably at the bottom of the unloading box 51, which is convenient for the operator to push out the full collecting vehicle 52 for subsequent processing, thereby improving the operating convenience and work efficiency of the entire classification processing device;

[0044] Partition 1 57 inside the collecting vehicle 52 serves to separate different types of raw materials, so that metal impurities of different sizes after screening can be stored separately, which is convenient for subsequent classification, recycling and reuse.

[0045] like Figures 8 to 10As shown, the magnetic separation component 4 also includes a vibration mechanism 47, which includes a fixed plate 474 and a vibration plate 475. The fixed plate 474 is fixedly connected to the inside of the shell 1, and the vibration plate 475 is slidably connected to the inside of the shell 1 and fits with the top inner wall of the conveyor belt 2. The top of the discharge box 51 is symmetrically rotatably connected to a drive rod 472 that penetrates into the shell 1. The drive rod 472 and the cleaning roller 54 are both connected by a transmission system 471. The four corners of the upper surface of the fixed plate 474 are fixedly connected to a limiting sleeve 476, and a spring 2 478 is fixedly connected between the vibration plate 475 and the limiting sleeve 476. Two cams 473 are fixedly connected to the outer side of the drive rod 472, and the four corners of the lower surface of the vibration plate 475 are fixedly connected to a limiting rod 477, and the limiting rod 477 penetrates the spring 2 478 and is slidably connected to the inner side of the limiting sleeve 476.

[0046] When the embodiment of the present invention is actually applied, when the cleaning roller 54 rotates, the driving rod 472 is driven by the transmission system 1 471 to rotate synchronously in the shell 1 and the unloading box 51. The cam 473 on the outer side of the driving rod 472 continuously contacts and separates from the vibration plate 475 as it rotates. When the protruding part of the cam 473 contacts the vibration plate 475, the vibration plate 475 is pushed to move upward against the elastic force of the spring 2 478. When the protruding part of the cam 473 rotates away from the vibration plate 475, the vibration plate 475 falls rapidly under the restoring force of the spring 2 478, so that the vibration plate 475 continuously reciprocates in the vertical direction. Since the vibration plate 475 fits the top inner wall of the conveyor belt 2, its vibration can be transmitted to the conveyor belt 2, so that the raw materials on the conveyor belt 2 also vibrate, which helps to loosen the raw materials and make the combination between the metal impurities and the raw materials looser, which is more conducive to the adsorption and separation of the metal impurities by the electromagnet 42.

[0047] Among them, the sliding of the limiting rod 477 in the limiting sleeve 476 plays a guiding and limiting role, ensuring that the vibration direction of the vibration plate 475 is stable and will not deviate or shake, thereby improving the working stability and reliability of the vibration mechanism 47.

[0048] As one case of an embodiment of the present invention, the vibration mechanism 47 can also adopt a vibration motor, an electromagnetic vibrator and a pneumatic vibrator to improve the separation effect between the metal impurities and the raw materials.

[0049] like Figure 3 and Fig. 9 As shown, the inner wall of the housing 1 is symmetrically provided with limiting grooves adapted to the conveyor belt 2, and the two ends of the conveyor belt 2 are respectively slidably connected in the two limiting grooves.

[0050] When the embodiment of the present invention is actually used, the limiting grooves symmetrically opened on the inner wall of the shell 1 and adapted to the conveyor belt 2 play a precise guiding and limiting role for the conveyor belt 2, effectively reducing adverse conditions such as deviation, swinging or twisting of the conveyor belt 2 during operation, and ensuring the smoothness and reliability of the conveying process.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
